Cuts v0.5.0 to PyPI.

Pre-flight passed (ruff/pyright/pytest, 2753 passed, 97.75% coverage); uv build + uvx twine check PASSED on wheel and sdist. CHANGELOG promoted from [Unreleased] to [0.5.0] — 2026-05-30.

Release branch is based on dev (not main) — main was at v0.4.0 and dev carried the v0.5.0 content (#159 column types, #136 OpenAI, #137 Gemini, #136 QG fixes). 16 commits flow into main with this merge.

TestPyPI smoke for 0.5.0.dev0 (same dev HEAD): https://test.pypi.org/project/signalforge-dbt/0.5.0.dev0/ — clean-room install on Python 3.11 floor PASSED.

After merge: tag v0.5.0 on main HEAD, create GitHub Release with the curated [0.5.0] CHANGELOG section, then open the next-dev bump PR (chore: begin 0.6.0.dev0) targeting dev.

* Add super plan for #135: provider-neutral LLM seam

Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

* Mark #135 plan published (PR #148)

Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

* Mark #135 plan devolved (beads epic bd_1-scaffolding-j2c)

Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

* bd_1-scaffolding-j2c.1: US-001 provider foundation (ExceptionCategory, UsageMetrics, LLMProvider ABC, registry)

Adds the provider-neutral LLM seam foundation (DEC-001/002/003 of #135):

- src/signalforge/llm/providers.py: ExceptionCategory (5-member enum),
  UsageMetrics (frozen pydantic value object, cache fields default 0),
  LLMProvider ABC, and the process-level registry (register_provider /
  provider_for). No vendor behaviour wired; registry starts empty.
- UnknownProviderError(LLMError) in errors.py — lists available registered
  provider names, repr-safe message, default_remediation; registered at
  CLI exit-code tier 2 (looked-up-identifier-not-in-table input failure).
- Exported the new public names from signalforge.llm.__all__; updated the
  documented-surface lists in test_public_api.py / test_schema.py and the
  errors count in test_errors.py.

* bd_1-scaffolding-j2c.2: US-002 AnthropicProvider strategy + _anthropic_client rename + AST scan

Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

* bd_1-scaffolding-j2c.3: US-003 generic call_llm orchestrator (rename, capability gating, strategy dispatch)

Collapse call_anthropic into a provider-neutral call_llm orchestrator:
- Resolve strategy via provider_for(provider); build client via
  strategy.make_client() when client is None (DEC-006).
- Pre-send count gate now gated on strategy.supports_token_count; cache
  marker / beta header + dual-zero anomaly WARNING gated on
  supports_prompt_caching (DEC-008). Anthropic = both True ⇒ byte-identical.
- Retry loop dispatches on strategy.classify_exception -> ExceptionCategory
  (DEC-001) instead of catching Anthropic SDK classes directly; per-class
  budgets, backoff math, WARNING shape, exhaustion raises preserved.
- Response assembled via strategy.extract_text_blocks/extract_usage.
- Neutral _LLMClientProtocol narrows the resolved client so no vendor-SDK
  type / type-checker suppression leaks into llm.client (DEC-012 confinement).

Drop call_anthropic (name + __all__); add call_llm. Migrate draft_from_request
and grade._grade_one call sites + all client/retry/public-api/schema tests.

Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

* bd_1-scaffolding-j2c.4: US-004 provider config field + stage threading + CLI client-construction migration

DEC-006/007 of #135. Adds a registry-validated `provider: str = "anthropic"`
field to DraftConfig and GradeConfig, each with a field_validator that
delegates to providers.provider_for (raises UnknownProviderError listing
available names on an unknown value — fails loud at config load). Threads
provider=config.provider into call_llm from draft_from_request and
grade._grade_one.

Migrates the CLI generate path off the in-CLI _make_anthropic_client helper
(removed): the real-run draft/grade stages now pass client=None so call_llm
lazy-builds the client via the configured provider. The --estimate
short-circuit (Anthropic-specific count_tokens) builds its concrete client via
provider_for(draft_config.provider).make_client(). Migrates the 7 CLI
monkeypatch tests: 5 batch/select tests drop the orphaned make_anthropic_client
mock; the estimate test patches AnthropicProvider.make_client; test_lint
unchanged (it patches the LLM shim, which still exists).

* bd_1-scaffolding-j2c.5: US-005 no-cache fake provider neutrality proof (AC #2/#3)

Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

* bd_1-scaffolding-j2c.6: US-006 docs + surface parity (docs/ portion)

Update operator-facing docs for the provider-neutral LLM seam (#135):
- call_anthropic -> call_llm; llm._client -> llm._anthropic_client
- document the provider config knob (llm.provider / grade.provider),
  default "anthropic", registry-validated, forward-looking plugin seam
- note prompt caching + count_tokens are now provider capabilities
  (supports_prompt_caching / supports_token_count); Anthropic unchanged

Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

* bd_1-scaffolding-j2c.6: US-006 .claude/rules seam-rename + provider-seam accuracy

Orchestrator-only rule-file edits (workers can't write .claude/ in worktrees).

Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

* bd_1-scaffolding-j2c.7: Quality gate — fix bugs from code review

- providers.build_count_tokens_kwargs: correct docstring (probe omits the
  cache_control marker because it doesn't affect the token count; the old
  claim of "matching the inline call_anthropic probe" was inaccurate).
- call_llm: gate cache_marker_active on BOTH supports_prompt_caching AND
  supports_token_count, so a future caching=True/token_count=False provider
  degrades to no-caching rather than sending an unvalidated cache_control
  marker (no sub-minimum drop / no oversize cap). Anthropic is True/True so
  the default path is a no-op. (4-pass review latent-trap finding.)

CodeRabbit: skill not available in this environment — skipped.

Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

* bd_1-scaffolding-j2c.8: Patterns & Memory — provider-seam convention + QG lesson

- llm-drafter.md: capability-gating lesson (gate the cache marker on BOTH
  supports_prompt_caching AND supports_token_count — the #135 QG latent-trap
  finding) for future #136/#137 provider authors.
- Added `provider` to the documented `llm:` config block.
- Reference section now cites plans/super/135 + the no-cache neutrality proof.

* #135: close Codecov patch gaps — count_tokens probe error mapping + classify fallthrough

The provider-neutral refactor rewrote the count_tokens pre-send probe's
error-mapping as new lines (auth/rate-limit/conn/5xx/other -> typed LLMError,
no retry on the probe) that the existing retry tests (messages.create path)
never exercised. Add 6 probe-failure tests + a missing-input_tokens case
(client.py 320-348 now covered, 87% -> 96%).

Also cover AnthropicProvider.classify_exception's defensive fallthrough for a
non-5xx/non-4xx-non-auth APIStatusError (3xx) -> NO_RETRY (providers.py -> 100%).

Remaining uncovered client.py helper branches (_extract_text_blocks /
_extract_usage_field malformed-response raises) are pre-existing and not part
of the #135 diff.

Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

* #135: address PR review (CodeRabbit/Copilot)

- Stale-symbol docstrings: rename every `call_anthropic` :func: reference to
  `call_llm` across llm/{__init__,models,_anthropic_client,providers}.py,
  draft/schema.py, grade/{engine,config,errors}.py, cli/_estimate.py; reword
  the AnthropicProvider "preparatory refactor" note (US-003 already collapsed
  the duplication); rewrite the llm package docstring to the provider-neutral
  seam.
- client.py: count_tokens NO_RETRY fallback message no longer claims a "status"
  (it also covers non-status exceptions) — now "failed with a non-retryable error".
- generate.py --estimate: fail fast with CliInputError when draft.provider !=
  grade.provider or the provider isn't 'anthropic' (the estimate engine drives a
  single Anthropic-cast count_tokens client across both configs). + 2 regression
  tests.
- plan SD-1: drop the stale `Literal` wording (DEC-007 settled it as a
  registry-validated str).

* docs(readme): refresh status, generalize config, redraft roadmap

The v0.1 "Status:" line was four releases stale and BigQuery-only.
Replace with a Supported-warehouses block covering BigQuery (v0.1) and
Snowflake (v0.3 — incl. the deferred aggregate-only / column_stats
limitation), generalize Configuration to dispatch on dbt profile type,
and redraft the Roadmap into Shipped (v0.1/v0.2/v0.3 with release dates)
+ Planned (Gemini/OpenAI → installable skill → Airflow → GitHub Action
→ rubric customization → dbt Fusion). Drop the now-stale "prune-existing
is dev-branch only" and "first four ship; prune-existing is v0.2 dev"
callouts.

Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

* docs(readme): add custom-business-logic callout, strip non-roadmap version markers

- Add a **Custom business logic** paragraph alongside Supported warehouses,
  explaining `meta.signalforge.business_rules` → `custom_sql` drafting + the
  ownership-marker write semantics + always-pass drop behaviour.
- Remove every version marker outside the Roadmap section: "since v0.1/v0.3"
  in the warehouses block, "*(v0.2)*" on the prune-existing bullet, the "v0.2
  default" config comment, the "(v0.1)"/"(v0.3)" subsection headers, and the
  "pre-alpha … v0.1 milestone" line in Contributing.

Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

* docs(readme): reorganize scope callouts; promote Supported warehouses to its own H2

The two bolded standalone paragraphs at the top of the README (Supported
warehouses, Custom business logic) sat before the "Why this exists" pitch
and front-loaded dense capability detail. The custom-business-logic block
was also triple-covered (standalone block + "What it does" bullet +
Quick-start worked example).

- Drop both standalone bolded paragraphs from the top.
- Promote Supported warehouses to a proper H2 between "How it works"
  and the "Live on PyPI" callout — brief, points to Configuration for
  per-warehouse setup; Snowflake's known limitation stays in its single
  home under Configuration > Snowflake.
- Strengthen the custom-business-rule bullet in "What it does" with the
  "fifth test type" framing and a direct link to the worked example, so
  the feature stays prominent without a redundant top-of-readme banner.

New flow: pitch → features → architecture → scope → quickstart → reference.

* #136: super plan for OpenAI grading provider

Phase: detailing (awaiting approval).

13 DECs captured: Chat Completions API, no provider/model cross-validation,
fully wire --estimate for OpenAI (new estimate_input_tokens ABC), default
judge gpt-4o, scope both grade + draft, server-side response_format=json_object,
four pricing SKUs (gpt-4o, -mini, 4.1, 4-turbo), live smoke covers grade +
estimate, .messages adapter wraps chat.completions, AST Scan 3 extension,
[openai] extra + lazy tiktoken, Anthropic estimate byte-identity floor.

9 stories: shim + AST confinement, OpenAIProvider + registration, FakeOpenAIClient
+ neutrality test, pricing entries, --estimate provider-aware counting,
live gated smokes, docs, Quality Gate, Patterns & Memory.

* #136: link plan to PR #152 (phase=published)

Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

* #136: apply 5 plan revisions from #137 cross-review

Cross-review against #137 (Gemini grading) plan surfaced 5 substantive gaps
in the OpenAI plan:

1. DEC-010 — fix wording: a NEW 9th AST scan (Scan 3 is Anthropic-specific),
   not an extension. Reuse _QualifiedNameCallFinder + three-pattern bypass
   regression test per testing-signal.md.
2. DEC-012 — fix pyproject.toml listing: three slots in lockstep
   ([project.optional-dependencies].openai + .dev + [dependency-groups].dev),
   mirroring Snowflake precedent per python-build.md. Plan previously named
   only two.
3. DEC-014 (new) — codify the _load_openai_exception_classes empty-tuple
   fallback on ImportError (mirrors AnthropicProvider). Includes refusal /
   content-filter symmetry note explaining why OpenAI needs no Gemini-style
   safety_filter typed-degrade DEC.
4. US-006 — add a third live test (draft_schema) honouring DEC-005's
   "scope both stages" commitment at live level too. DEC-008 updated to
   match (three tests, not two).
5. New "Open notes for implementation" section — pragmatic SDK-class-name
   verification, .messages adapter shape confirmation, tiktoken fallback
   table, response_format prompt-requirement check, Anthropic byte-identity
   snapshot capture protocol.

Plus a new "Worker-writability routing" section codifying that US-009
(Patterns & Memory) is orchestrator-only because it edits .claude/rules/,
mirroring #137's same routing.

Plan grows from 319 → 343 lines (+40/-17).

* #136: devolve plan into bd beads (epic bd_1-scaffolding-4tw + 9 tasks)

Fills in the Beads manifest section. Epic bd_1-scaffolding-4tw with 9
child tasks (US-001 … US-009) created with dep edges per the plan's
"Depends on:" lines:

  US-001 → none                          (READY)
  US-002 → US-001
  US-003 → US-002
  US-004 → none (parallel-safe)          (READY)
  US-005 → US-002, US-004
  US-006 → US-002, US-005
  US-007 → US-001, US-002, US-005
  US-008 → US-001..US-007                (QG)
  US-009 → US-008                        (P&M; orchestrator-only)

Cross-epic gate wired downstream: #137's sentinel bd_1-scaffolding-41a
now DEPENDS ON US-009, so #137 US-007 stays mechanically blocked until
this epic completes + sentinel closes after PR #152 merges to dev.

Parallel-safe at the entry points: US-001 and US-004 edit disjoint
files (shim/pyproject/AST vs pricing) — ralph-serialize-shared-registry
does not apply. Run concurrently.

bd ready (post-devolve) surfaces .1 + .4 of this epic + the two epics
themselves + the unrelated Airflow integration.

* bd_1-scaffolding-4tw.4: #136 US-004 — OpenAI pricing SKUs (gpt-4o + 3 siblings)

Adds four OpenAI SKUs to _PRICES_MUTABLE per DEC-007: gpt-4o (default
judge per DEC-004), gpt-4o-mini (budget), gpt-4.1 (newer flagship),
gpt-4-turbo (back-compat). Cache fields = 0.0 (OpenAI has no equivalent
cache discount). PRICE_TABLE_VERSION bumped to 2026-05-28.

Anthropic SKUs unchanged (byte-identical) — Anthropic estimate
byte-identity floor (DEC-013) preserved at the pricing layer.

Tests assert: non-zero input/output rates + zero cache fields for all
four; unknown model still raises EstimateUnknownModelError; Anthropic
SKUs unchanged; version bump pinned.

OpenAI per-MTok rates are calibration figures captured at PR-prep time
pending operator verification against https://openai.com/api/pricing/;
the figures are sanity-check baselines, not billing guarantees.

Traces: DEC-003, DEC-004, DEC-007.

* bd_1-scaffolding-4tw.1: #136 US-001 — _openai_client.py shim + [openai] extra + 9th AST scan

Implements the per-vendor shim confining every openai SDK type ignore.
Adds [openai] optional-dep extra (openai + tiktoken) in three-slot
lockstep across [project.optional-dependencies].openai, .dev, and
[dependency-groups].dev. Adds the new 9th AST scan in
tests/test_audit_completeness.py reusing _QualifiedNameCallFinder
(NOT an extension of Scan 3 — Scan 3 is Anthropic-specific) and a
companion per-file confinement test mirroring Snowflake's. Bumps the
docstring tally 8→9.

DEC-014 empty-tuple ImportError fallback on _load_openai_exception_classes
mirrors AnthropicProvider; tiktoken cl100k_base fallback for unknown
model ids.

Traces: DEC-001, DEC-009, DEC-010, DEC-012, DEC-014.

* bd_1-scaffolding-4tw.2: #136 US-002 — OpenAIProvider + registration + config-validator coverage

Implements OpenAIProvider(LLMProvider) with both capability flags False
(no prompt caching, no pre-send token count) — mirrors FakeNoCacheProvider
end-to-end shape. build_create_kwargs attaches response_format=
{type: json_object} per DEC-006 (server-side JSON enforcement); no
cache_control / extra_headers. extract_text_blocks reads
response.choices[0].message.content; extract_usage maps usage.prompt_tokens
+ completion_tokens → UsageMetrics with cache fields 0. classify_exception
covers all five ExceptionCategory branches via _load_openai_exception_classes
from the US-001 shim.

register_provider(OpenAIProvider()) at module scope so GradeConfig/
DraftConfig validators accept provider='openai'. Exported from
signalforge.llm.__init__.

Tests pin: each ABC method's contract; config validator acceptance for
both stages; UnknownProviderError lists both anthropic and openai.

Traces: DEC-001, DEC-005, DEC-006, DEC-009, DEC-011.

* bd_1-scaffolding-4tw.3: #136 US-003 — FakeOpenAIClient + grade neutrality e2e

Adds tests/llm/_fake_openai.py with FakeOpenAIClient + expect_messages_create
API mirroring FakeAnthropicClient verbatim. Support dataclasses match the
real chat-completions response shape (choices[0].message.content; usage
with prompt_tokens + completion_tokens).

Adds tests/grade/test_provider_neutrality_openai.py — the OpenAI analogue
of the FakeNoCacheProvider neutrality proof. Asserts cache_*=0 in JSONL
audit, blake2b-8 reproducibility hashes present, sidecar drift-detector
round-trip, no dual-zero cache-anomaly WARNING in caplog, all expectations
consumed.

Traces: DEC-001, DEC-005, DEC-006, DEC-009, DEC-011.

Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

* bd_1-scaffolding-4tw.5: #136 US-005 — --estimate provider-aware token counting

Adds LLMProvider.estimate_input_tokens(model, text, *, client=None) -> int
as an abstract method on the ABC (DEC-003). AnthropicProvider impl
delegates to the SDK's messages.count_tokens with a single user-message
text envelope; OpenAIProvider impl delegates to _count_openai_tokens
(tiktoken with cl100k_base fallback per DEC-012); FakeNoCacheProvider
and _DummyProvider impls return trivial deterministic answers so the
existing neutrality + registry tests still pass.

Refactors cli/_estimate.py: _count_draft_tokens and the grader-side
equivalent dispatch through provider_for(config.provider).estimate_input_tokens
— no more hard-coded anthropic_client.messages.count_tokens calls. The
engine signature relaxes anthropic_client to 'object | None' so the
OpenAI path can pass None (tiktoken is local). Lifts the
'--estimate currently supports only provider=anthropic' gate in
cli/generate.py; the divergent-providers check stays (the engine still
takes one optional client).

Pins DEC-013 Anthropic byte-identity floor via
tests/cli/test_estimate.py::test_estimate_anthropic_byte_identity_golden
and tests/fixtures/estimate/anthropic_byte_identity_golden.txt (captured
2026-05-28 before the refactor; reproduced verbatim after). New
companion tests prove the OpenAI path produces non-zero token counts
+ non-zero USD, ignores the threaded anthropic_client, and goes through
_count_openai_tokens (patched-helper assertion).

Traces: DEC-003, DEC-007, DEC-012, DEC-013.

* bd_1-scaffolding-4tw.7: #136 US-007 — operator docs + CHANGELOG (worker-writable portion)

Updates operator-facing documentation surfaces for OpenAI grading +
drafting:
- docs/grade-ops.md — OpenAI provider section (config snippet,
  OPENAI_API_KEY, no-cache caveat, live smoke gating link)
- docs/draft-ops.md — equivalent for llm.provider: openai
- docs/cost-estimate-ops.md — tiktoken note, [openai] extra install,
  four pricing SKUs
- CHANGELOG.md — [Unreleased] Added entry for #136
- README.md — provider enumeration extended (if applicable)

The .claude/rules/llm-drafter.md update is deferred to US-009

* bd_1-scaffolding-4tw.6: #136 US-006 — live gated smoke tests (openai marker + 3 tests)

Adds @pytest.mark.openai marker + three gated live-API tests:
- tests/grade/test_smoke_real_api_openai.py — grade_artifacts(provider=openai)
- tests/draft/test_smoke_real_api_openai.py — draft_schema(provider=openai)
  (honors DEC-005 both-stages at live level)
- tests/cli/test_e2e_estimate_openai.py — generate --estimate openai

All three env-gated on SF_RUN_OPENAI=1 + OPENAI_API_KEY via belt-and-
suspenders _skip_reason() helper per testing-signal.md. Marker registered
in pyproject.toml + added to addopts exclusion so default pytest doesn't
collect them. CONTRIBUTING.md documents the maintainer-only run pattern.

* bd_1-scaffolding-4tw.8: #136 Quality Gate — fix 2 majors + 1 minor from code review x4

Code-review pass 3 surfaced two correctness MAJORS + pass 4 surfaced
a doc MINOR; all fixed inline per /ralph-run Step 3b. Pass 1, 2, 4
(other surfaces) reported no correctness bugs.

MAJOR 1 — EstimateUnknownModelError.default_remediation enumerated
only the three Anthropic SKUs. An operator typo on an OpenAI SKU
got pointed at Anthropic options (violates "errors carry remediation"
in manifest-readers.md). Updated to enumerate all 7 SKUs
(claude-sonnet-4-6, claude-opus-4-7, claude-haiku-4-5, gpt-4o,
gpt-4o-mini, gpt-4.1, gpt-4-turbo) + refreshed the locked-text test
that pinned the stale string.

MAJOR 2 — AnthropicProvider.estimate_input_tokens dropped the
pre-refactor `system=` kwarg, concatenating system+cached+dynamic
into a single user-content string. Anthropic's server-side tokenizer
counts the system block with its own envelope tokens; without the
kwarg, real-API counts under-report by the system-envelope size.
The fake-driven byte-identity test passed only because the fake
returned canned input_tokens regardless of kwargs (so rendered-output
identity held, but DEC-013's "byte-identity vs the pre-refactor
Anthropic count_tokens call" spirit broke at the real-API level).

Fix extends the ABC signature with a keyword-only `system: str = ""`
parameter. AnthropicProvider passes it via `system=` kwarg when
non-empty (matches pre-refactor real-API call shape). OpenAIProvider
concatenates `system + text` before tiktoken (tiktoken has no
system-envelope distinction; the total still counts every token).
FakeNoCacheProvider concatenates for the word-count proxy.
_DummyProvider gains the new kwarg for ABC parity. cli/_estimate.py
callers (_count_draft_tokens, _count_grade_criterion_tokens) thread
`system=` separately; grade-side preserves the pre-existing
double-count of the rubric (passed as both system= AND in user content)
to keep byte-identity with the pre-refactor shape.

MINOR — docs/grade-ops.md:118 config-snippet comment said "only
anthropic registered today", contradicting the same file's later
"## OpenAI provider" section and docs/draft-ops.md's correct
wording. Updated to mirror draft-ops's form.

Validation: ruff/pyright/pytest all green (2498 passed, 62 deselected,
97.34% coverage); wheel_smoke green (2 passed).

* bd_1-scaffolding-4tw.9: #136 Patterns & Memory — codify OpenAI seam conventions

Orchestrator-only commit (workers can't write under .claude/ in
worktrees per ralph-worker-claude-dir-perms.md).

Updates .claude/rules/llm-drafter.md to capture three durable patterns
from #136:

1. Provider-neutral seam — adds OpenAI as the second registered
   provider (name="openai", both capability flags False) and extends
   the LLMProvider ABC surface enumeration with the new
   estimate_input_tokens(model, text, *, system="", client=None)
   method (#136 US-005).

2. "OpenAI provider shape" subsection — codifies the .messages.create
   façade adapter pattern (SimpleNamespace delegating to
   chat.completions.create), the response_format={type:json_object}
   server-side JSON enforcement (with the cross-ref to issue #144's
   tolerant parser as fallback), and the tiktoken cl100k_base
   fallback for unknown model ids. This becomes the canonical
   precedent for #137 Gemini's response_mime_type=application/json
   equivalent.

3. estimate_input_tokens(*, system=...) — documents the load-bearing
   reason the system envelope is threaded separately (Anthropic's
   server-side tokenizer applies system-block envelope tokens; dropping
   the kwarg under-reports real-API counts silently because
   fake-driven byte-identity tests can't catch call-shape drift). Also
   pins the deliberate double-count of system_and_rubric in
   _count_grade_criterion_tokens as pre-existing behaviour that must
   be preserved.

Bumps AST-scan tally section from "four" → "five" (adds the openai.OpenAI
9th-project-scan); flags #137 Gemini as the 10th. Updates the
References block with #136 plan + new files.

Memory entry: ~/.claude/projects/.../memory/fake-driven-byte-identity-
blind-spot.md captures the QG lesson (fakes return canned values
regardless of kwargs → call-shape drift slips past rendered-output
snapshots → needs explicit kwargs-shape assertion OR live test).
Indexed in MEMORY.md.

Validation: all four canonical gates green (2498 passed, 97.34%
coverage).

* #136: address PR #152 review (6 actionable + meta)

Copilot:
- MAJOR _estimate.py:359 — OpenAI grade-side over-counted rubric. The
  first QG fix preserved a pre-existing Anthropic double-count of
  system_and_rubric (passed as both system= AND in user content),
  which triple-counted on OpenAI (system→system+text concat → rubric
  prefix in text). Corrected to match the runtime grader call: rubric
  in system= once, artifact envelope in user content. Anthropic real-
  API counts drop one rubric copy from the buggy pre-refactor bytes;
  OpenAI counts each input once. Fake-driven byte-identity golden
  still passes (canned token counts are call-shape-agnostic).
  CHANGELOG documents the calibration shift.
- NIT _estimate.py:421 — renamed anthropic_client → client. Type was
  already object | None and forwarded to whichever provider strategy
  is active; old name implied Anthropic-only and would mislead a
  future #137 Gemini wiring. CLI in generate.py already passed None
  for non-Anthropic; rename surfaces the contract without behaviour
  change.
- META plan/PR description — addressed by updating the PR body
  separately (not part of this commit).

CodeRabbit:
- CONTRIBUTING.md:64 — added snowflake to the gated-marker audit
  command + the corresponding SNOWFLAKE_* env vars.
- tests/llm/_fake_provider.py:234 — boundary-word undercount fix in
  the FakeNoCacheProvider word-count proxy (f"{system} {text}" with
  a delimiter; was system+text which merged the last word of system
  with the first word of text under .split()).
- tests/llm/test_openai_client_confinement.py:47 — glob("*.py") →
  rglob("*.py") so the confinement scan catches openai-mentioning
  ignore directives in any future nested signalforge/llm/ subpackage,
  not just top-level files. Path display becomes relative-to-_LLM_DIR.
- tests/test_audit_completeness.py:1080 — closed the "call-before-
  import alias" bypass on _AttributeCallFinder by adding a two-pass
  visit_Module that pre-collects every alias module-wide before
  visiting any Call node. Mirrors the same fix already shipped on
  _QualifiedNameCallFinder (PR #69 / DEC-013). Pattern-4 regression
  test added.

Validation: ruff/format/pyright/pytest all green (2498 passed,
97.34% coverage); wheel_smoke green.

* #136: close PR #152 codecov gaps (9 lines → 0)

Codecov flagged 91.82% patch coverage with 9 lines missing across
3 files. Closed all 9 with 6 focused unit tests:

src/signalforge/llm/_openai_client.py (was 85%, now 100%):
- _OpenAIClientAdapter.__init__ + ._messages_create — no production
  caller exercises the adapter (orchestrator drives via
  FakeOpenAIClient which has its own .messages.create); added
  test_openai_client_adapter_messages_create_delegates_to_chat_completions
  that builds a SimpleNamespace raw client and pins the delegation
  + kwargs forwarding.
- _count_openai_tokens cl100k_base fallback (DEC-012 unknown-model
  branch) — added test_count_openai_tokens_falls_back_to_cl100k_base_
  for_unknown_model.

src/signalforge/llm/providers.py (was 98%, now 100%):
- AnthropicProvider.estimate_input_tokens no-system-kwarg arm (the
  else branch added in QG) — added test_anthropic_provider_estimate_
  input_tokens_skips_system_kwarg_when_empty, which ALSO pins the
  load-bearing invariant that an empty system MUST be omitted from
  the SDK kwargs (otherwise the count carries a spurious system=""
  block).
- LLMResponseFormatError raise on missing input_tokens — added
  test_anthropic_provider_estimate_input_tokens_raises_on_missing_
  input_tokens.
- OpenAIProvider.extract_text_blocks missing-message arm — added
  test_openai_provider_extract_text_blocks_missing_message_attr_
  raises (distinct from the existing content=None and empty-choices
  cases — those exercise different arms).

src/signalforge/cli/generate.py:846 (was 66%, now covered):
- The non-Anthropic `client = None` branch in cmd_generate's
  --estimate short-circuit — exercised only by the
  @pytest.mark.openai live smoke before. Added test_generate_
  estimate_openai_provider_passes_client_none_to_engine that drives
  cmd_generate with llm.provider: openai + grade.provider: openai
  in a tmp signalforge.yml, spies on AnthropicProvider.make_client
  to confirm it's NEVER called on the openai path, and captures the
  client kwarg into estimate(...) to pin client=None. The remaining
  7 uncovered lines in generate.py are pre-PR and out of scope.

Total: 2504 passed (was 2498), 97.47% coverage (was 97.34%), no
new gated tests added (all unit tests, default-CI-included).

* #137: Gemini grading provider (plan)

Super plan for #137 (Gemini grading provider) — depends on #135 (merged).
9 stories: shim + provider + extra + fake/unit + neutrality + live +
docs + QG + P&M. Caching deferred (both capability flags False);
safety-filter no-content surfaces as LLMResponseFormatError →
grade GradeLLMError degrade. Both drafter and grader covered.

* #137: extend plan after comparison with #136 OpenAI plan

Closes the three gaps surfaced by the #136 comparison:

- Add --estimate integration (DEC-016): GeminiProvider.estimate_input_tokens
  via native client.models.count_tokens (cleaner than #136's tiktoken path —
  Gemini has a first-party count endpoint).
- Add 3 Gemini pricing SKUs to pricing.py (DEC-017): gemini-2.5-pro,
  gemini-2.5-flash, gemini-2.0-flash; bump PRICE_TABLE_VERSION.
- Add server-side JSON enforcement (DEC-018): response_mime_type=
  application/json — mirrors #136 DEC-006.
- Add CHANGELOG entry to docs story (US-009).
- Add wheel_smoke to QG (new [gemini] extra changes packaging).
- Sequence after #136 (DEC-019): inherit ABC extension + estimate refactor.

New stories: US-006 (pricing, parallel-safe), US-007 (estimate impl,
depends on #136). Old US-006/007 renumbered to US-008/009.

* #137: apply 3 plan refinements from #136 cross-review

Closes the smaller gaps surfaced by re-reviewing #137 against #136 after
the #136 plan was tightened (520b36c):

1. DEC-009 — merge-order-conditional AST scan tally. Currently said "8 → 9"
   unconditionally, but DEC-019 specifies #137 ships AFTER #136. Realistic
   bump is 9 → 10 (since #136's openai.OpenAI scan bumps 8 → 9 first);
   added the fallback wording for the slipped-sequencing case.
2. Dedicated "Worker-writability routing" top-level section codifying that
   Patterns & Memory is orchestrator-only (.claude/rules/ writes). Was a
   one-line architecture-review row; now a durable section that mirrors
   #136's codification — future #138+ provider plans copy the pattern.
3. Open notes for implementation — two additions:
   - response_mime_type requires NO prompt keyword (contrast with OpenAI's
     response_format which fails without "json" in prompt). Prevents a
     future maintainer adding defensive prompt text.
   - pricing.lookup zero cache fields math validation (symmetric to #136
     verification item).

Major gaps from the prior cross-review (--estimate, pricing, dual-listing,
JSON enforcement, CHANGELOG, three live tests, sequencing) were already
addressed in b28c0b5.

* #137: devolve plan to beads (phase=devolved)

Epic: bd_1-scaffolding-txe
Tasks: 11 (US-001 through US-009 + Quality Gate + Patterns & Memory)
Dependencies: 19 edges per the plan's dependency graph
Ready queue: US-001 (shim) + US-006 (pricing, parallel-safe)

US-007 (--estimate integration) is blocked on US-002 + US-006 AND
carries a cross-epic gate on #136 landing first per DEC-019 — that
sequencing is documented in the task's description rather than wired
as a bead dep since #136's beads live in a different epic.

US-011 (Patterns & Memory) is flagged orchestrator-only because it
edits .claude/rules/ which Ralph workers can't write under in
worktrees (per the Worker-writability routing section of the plan).

Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

* #137: adjust plan now that #136 is being implemented first

Folds devolve-time annotations (phase=devolved, beads epic
bd_1-scaffolding-txe, per-task status + cross-epic blocker on US-007)
together with five #136-driven adjustments:

1. AST-scan tally locked to 10th (not 9th) — #136 owns the 8→9 bump
   for openai.OpenAI; #137 takes 9→10 for genai.Client. Updated in
   DEC-009, US-001, P&M, and Open notes.
2. DEC-019 sharpened: #136 plan → #136 implementation; explicit rebase
   guidance (rebase on dev after #136 merges) rather than contingency
   wording.
3. DEC-005 gains a refusal/content-filter symmetry note cross-ref'ing
   #136 DEC-014 — explains why OpenAI deliberately ships no
   safety-filter typed-degrade and why Gemini deliberately does.
4. New "Worker-writability routing" section mirroring #136's, codifying
   that P&M is orchestrator-only because it edits .claude/rules/.
5. Open notes extended with two pragmatic items parallel to #136's:
   - google-genai count_tokens response field-name verification
     (.total_tokens vs .total_token_count) at US-007 implementation.
   - Anthropic byte-identity snapshot ownership: #136 owns it; #137
     inherits it; the wiring is wrong if it moves the snapshot.

Plan grows 762 → 825 lines (+70/-30).

* bd_1-scaffolding-txe.6: #137 US-006 — add Gemini pricing SKUs (gemini-2.5-pro, gemini-2.5-flash, gemini-2.0-flash)

Adds three Gemini SKUs to _PRICES_MUTABLE per DEC-017, each with positive
input_per_mtok / output_per_mtok per Google's public Gemini API price page
and cache fields = 0.0 (v0.3 ships Gemini without an Anthropic-equivalent
prompt-cache discount). Bumps PRICE_TABLE_VERSION to "2026-05-27". Tests
parametrise the three SKUs, pin Anthropic SKU byte-identity (additive-only),
and assert lookup("gemini-unknown") still raises EstimateUnknownModelError.

cli/_estimate.py reads only input_per_mtok and output_per_mtok in the USD
math (lines 468, 511), so zero cache fields are safe — no divide-by-zero
or NaN risk. The EstimateUnknownModelError.default_remediation in
llm/errors.py still lists only the three Claude SKUs by name; per the
story scope ("pricing-only; DO NOT touch any other file") this is left
for a follow-up to broaden once the wider Gemini surface (provider class
+ --estimate integration in US-007) lands.

* bd_1-scaffolding-txe.1: #137 US-001 — _gemini_client.py shim + new AST confinement scan

Land the per-vendor Gemini SDK shim and the 9th AST audit-completeness
scan that confines genai.Client(...) constructions to it. Mirrors the
Anthropic shim shape verbatim — GeminiClientProtocol (with .messages
façade for US-002 and .models for US-007), lazy-import factory, frozen
_GeminiExceptionClasses dataclass with empty-tuple fallback per DEC-015
so the module imports cleanly without the [gemini] extra installed.

The new scan extends _AttributeCallFinder with an optional parent_module
parameter so the namespace-package shape `from google import genai;
genai.Client(...)` is caught alongside `from google.genai import Client`
and its alias variant — five planted-violation regression tests pin the
three bypass patterns plus a negative case and an Anthropic-path-unchanged
guard. A line-based confinement test
(tests/llm/test_gemini_client_confinement.py) rejects any
google.genai-mentioning `# type: ignore` outside the shim, mirroring
tests/warehouse/test_snowflake_client_confinement.py. The existing
Anthropic shim's regex-level confinement test narrowed from "any
ignore" to "anthropic-mentioning ignore" so the new Gemini shim's own
SDK ignores don't trip it. All four canonical validation steps pass;
2474 tests; coverage 97.33%.

* bd_1-scaffolding-txe.3: #137 US-003 — pyproject.toml [gemini] extra + dev-group sync

google-genai>=0.5,<1 listed in three pyproject slots in lockstep per DEC-010
(operator install, pip dev back-compat, uv dev group). uv.lock regenerated.

Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

* bd_1-scaffolding-txe.2: #137 US-002 — GeminiProvider(LLMProvider) + registration

GeminiProvider concrete strategy registered at module import; both capability
flags False per DEC-003. build_create_kwargs sets response_mime_type=
application/json (DEC-018) and maps system → system_instruction + single user
turn (DEC-004). Safety-blocked / no-content responses → LLMResponseFormatError
per DEC-005. Exception taxonomy per DEC-006 — verified against
google-genai==0.8.0.

Notes from verification against the installed SDK:

- google.genai.errors.APIError (the shared parent of ClientError +
  ServerError) stores the HTTP code on .code (an int), not .status_code —
  the classifier reads .code. ClientError covers 4xx (incl. 401/403/429);
  ServerError covers 5xx. ServerError is checked BEFORE ClientError so the
  narrower 5xx bucket cannot be shadowed by a future shared parent class.

- The SDK's models.generate_content(config=) accepts both
  GenerateContentConfig and the plain-dict GenerateContentConfigDict form.
  build_create_kwargs returns the plain-dict form so providers.py never
  imports google.genai.types at any scope — keeping
  test_gemini_client_confinement.py green and base-install module-import
  clean.

- The .messages.create façade required by the orchestrator is wired in
  GeminiProvider.make_client via a small _GeminiClientAdapter /
  _GeminiMessagesAdapter pair (the shim returns the bare client; US-002
  owns the adapter per the shim's docstring). The adapter forwards
  **kwargs straight to client.models.generate_content / count_tokens.

- Connection-flavoured exceptions (httpx.ConnectError /
  httpx.TimeoutException) leak through the SDK on hard network failures;
  the classifier handles them with a lazy httpx import and an
  ImportError-safe fallback to NO_RETRY.

Updates the pinned signalforge.llm __all__ surface in
tests/llm/test_public_api.py and tests/draft/test_schema.py to include the
new GeminiProvider re-export; adds DraftConfig/GradeConfig provider="gemini"
acceptance tests.

tests/llm/test_gemini_provider_via_fake.py drives GeminiProvider through

* #137: harden DEC-019 cross-epic gate via bd sentinel bead

DEC-019 was documentary only; bd_1-scaffolding-txe.7 (US-007) showed
as bd-ready despite the plan saying "wait for #136 to merge to dev."
A Ralph worker running `bd ready` would have picked it up and
rebase-fought #136 on providers.py / pricing.py / cli/_estimate.py
exactly as DEC-019 warns against.

Created sentinel bead bd_1-scaffolding-41a ("#136 OpenAI grading
PR #152 merged to dev") and wired bd_1-scaffolding-txe.7 to depend on
it. `bd ready` no longer surfaces US-007 until the sentinel closes.
Close the sentinel the moment #136 merges to dev → US-007 unblocks
automatically.

Updated DEC-019 + the beads manifest entry on US-007 to point at the
sentinel.

Replaces the merge-resolution NotImplementedError stub with a real
implementation via Gemini's native client.models.count_tokens
(first-party; no tiktoken equivalent). The --estimate cost-preview
path now works end-to-end for grade.provider: gemini and
llm.provider: gemini. Anthropic byte-identity golden unchanged
(verified against tests/fixtures/estimate/anthropic_byte_identity_golden.txt).

* bd_1-scaffolding-txe.10: #137 Quality Gate — fix bugs from 4-reviewer pass

Four parallel code-review passes surfaced 2 substantive code findings
and 5 documentation findings; all fixed below. CodeRabbit run skipped
(no skill available locally); maintainer can request post-merge.

Code fixes (reviewer 2 — tests):

- tests/test_audit_completeness.py: added the missing planted-violation
  regression test for the new parent_module codepath in
  _AttributeCallFinder. Covers Patterns 5-8 (namespace-package via
  from-google-import-genai, namespace alias, dotted-from-import,
  dotted-import-as) plus a negative check pinning that Pattern 7
  requires parent_module to be set. Mandated by testing-signal.md
  § "AST single-construction-seam scans must catch all three bypass
  patterns" — without this, a refactor of the parent_module branches
  could silently break Scan 10 at the exact moment a real Gemini-SDK
  construction was added outside _gemini_client.py.
- tests/grade/test_gemini_grade_live.py: added cache_*=0 assertion on
  every GradeEvent record (DEC-003 of #137). The docstring claimed
  this was tested but the assertion was missing — a grade-path
  bookkeeping regression would have slipped through the live smoke.

Doc fixes (reviewer 3 — docs):

- docs/grade-ops.md + docs/draft-ops.md: rewrote the "--estimate
  integration (deferred)" sections to reflect that US-007 SHIPPED in
  this PR. Both now describe the active behaviour (native
  client.models.count_tokens round-trip; failures surface as
  <unavailable>) instead of the pre-US-007 deferred state.
- CHANGELOG.md: updated the Gemini Unreleased bullet to advertise
  --estimate support as part of the #137 deliverable; reserved the
  "follow-up" framing for explicit Gemini context caching only.
- docs/cost-estimate-ops.md: added Gemini coverage in three places —
  the provider-aware token counting bullet list, a parallel "Gemini
  provider — [gemini] install extra" section (with the three
  registered SKUs in a table), and the maintainer live smoke set.
  File had ZERO Gemini coverage before this fix.
- README.md: added Google Gemini to the supported-providers section
  alongside Anthropic + OpenAI; moved the Gemini roadmap row from
  "Planned v0.4" into "Shipped v0.4" since it's landing in this PR.

Reviewer 1 (providers.py) and reviewer 4 (packaging + integration)
reported 0 bugs. Reviewer 2's LOW-priority findings (flake-prone
aggregate_complete assertion, loose substring on confinement scan,
missing 5xx-retry integration test) deferred — not correctness risks.

Validation after fixes:
- ruff check: passed
- ruff format --check: passed
- pyright: 0 errors, 0 warnings, 0 informations
- pytest: 2555 passed, 65 deselected, 97.51% coverage
- wheel_smoke: 2/2 passed (new [gemini] extra packaging intact)
- Anthropic byte-identity golden: passed (unchanged)

* bd_1-scaffolding-txe.11: #137 Patterns & Memory — durable rules for Gemini

Orchestrator-only commit (Ralph workers can't write under .claude/ in
worktrees per memory ralph-worker-claude-dir-perms.md).

.claude/rules/llm-drafter.md:
- AST scan tally bumped 5 → 6 (Scan 10 = genai.Client confinement
  via _AttributeCallFinder(parent_module="google")).
- New § "Gemini provider shape (#137 — the third concrete provider,
  no-cache via a namespace-package SDK)" with the four load-bearing
  patterns: .messages-over-.models.generate_content adapter,
  response_mime_type=application/json server-side JSON enforcement,
  safety-filter typed LLMResponseFormatError → grade degrade, and
  native models.count_tokens for --estimate (distinct from OpenAI's
  local tiktoken path).
- New § "Namespace-package SDKs (#137 generalisation)" documenting
  the parent_module parameter that catches the four namespace-package
  import shapes the no-parent path misses.
- Reference block extended with the #137 plan + the three new fakes
  + the two new neutrality test suites.
- "new vendor lands" wording generalised (#137 is no longer "next",
  it's "shipped"); Anthropic→OpenAI→Gemini lineage noted explicitly.

.claude/rules/grade-layer.md:
- Conservative degrade taxonomy DEC-002/DEC-015 entry for
  GradeLLMError extended with a sentence explaining Gemini's
  safety-filter / no-content response routes through the same path
  via the typed LLMResponseFormatError that GeminiProvider raises
  (DEC-005 of #137). Locks in the provider-neutral contract: a
  future vendor with a content-filter surface MUST route through
  LLMResponseFormatError, not a provider-specific switch in
  grade_artifacts.

* #137: Address PR review feedback (Copilot + CodeRabbit)

Five real issues fixed; three outdated threads resolved as-is.

Fixed:

1. src/signalforge/llm/_gemini_client.py — Copilot flagged that
   GeminiClientProtocol's docstring claimed the bare SDK client
   satisfies it, and _make_gemini_client was annotated to return
   GeminiClientProtocol despite returning the raw google.genai.Client
   (which has no .messages namespace). The protocol is satisfied only
   by the wrapped _GeminiClientAdapter (in providers.py) and by the
   test fake. Rewrote both docstrings; relaxed _make_gemini_client's
   return type to `Any` and explained the wrapper-on-top contract
   explicitly. Replaces the misleading "satisfies structurally" claim
   with the honest "bare SDK does NOT satisfy; wrapper does."

2. plans/super/137-gemini-grading.md (Discovery, line 98) — CodeRabbit
   flagged the stale PRICE_TABLE_VERSION = "2026-05-11". Annotated
   the reference as "at discovery time" and noted that US-006 and
   #136 both bump it.

3. plans/super/137-gemini-grading.md (Worker-writability routing) —
   CodeRabbit flagged a duplicated "## Worker-writability routing"
   heading. The duplicate must have crept in during the cross-review
   pass. Removed the second copy; kept the first canonical version.

4. tests/llm/test_pricing.py
   (test_lookup_raises_estimateunknownmodelerror_for_unknown_gemini_model)
   — CodeRabbit flagged that the test only validates `.model`,
   leaving the operator-facing remediation text drifting silently
   from the pricing table. Added a structural pin that the rendered
   exception names every Gemini SKU. Future SKU additions force a
   lockstep remediation update.

Outdated threads (3) — content already fixed by earlier commits; the
threads are kept resolved for hygiene:

5. tests/test_audit_completeness.py docstring "node.module == genai"
   note (Copilot, two threads). The actual scan handles the dotted-
   form via parent_module; the comments in the implementation
   already reflect this since the QG pass.

6. CONTRIBUTING.md pre-release excluded-marker list (CodeRabbit). The
   list was already extended to include `gemini` (and `snowflake`)
   during the QG fix in commit f15a469.

* #137: Address second-round PR review (Copilot, 4 new comments)

Two real findings fixed; two false positives documented.

Fixed:

1. pyproject.toml gemini marker description — Copilot flagged that
   the help text named only GOOGLE_API_KEY but the live tests also
   gate on SF_RUN_GEMINI=1. Updated to "requires SF_RUN_GEMINI=1 +
   GOOGLE_API_KEY" — mirrors the OpenAI marker's shape exactly.

2. src/signalforge/llm/providers.py::GeminiProvider.extract_usage —
   Copilot flagged that getattr(usage, "prompt_token_count", 0) or 0
   silently swallows missing/malformed SDK response shapes and feeds
   misleading 0/0 figures into the audit JSONL + --estimate math.
   Switched to the shared _extract_usage_field helper which raises
   LLMResponseFormatError on missing/non-int fields. Matches the
   Anthropic precedent (the OpenAI provider already uses the same
   helper). Added test_geminiprovider_extract_usage_missing_inner_
   field_raises pinning both the missing-field and non-int-type
   paths to keep them durable.

False positives (replied in resolve-threads):

3. _gemini_client.py:116 (`_make_gemini_client` return annotation):
   Copilot is reviewing the pre-commit-00dc673 diff. The previous
   round of fixes (commit 00dc673) already changed the return type
   to Any and rewrote the docstring to be honest that the bare SDK
   client does NOT satisfy GeminiClientProtocol; only the
   _GeminiClientAdapter wrapper does. Current file matches.

4. plans/super/137-gemini-grading.md:777 (duplicate Worker-
   writability routing): Same — the duplicate was already removed
   in 00dc673. Only one section now exists at line 757.

Validation:
- ruff check: passed
- ruff format --check: passed
- pyright: 0 errors, 0 warnings, 0 informations
- pytest: 2556 passed, 65 deselected, 97.55% coverage

* #155: super-plan — Gemini truncation + per-provider e2e gap

12 DECs covering:
- DEC-001/002/005: provider-neutral is_clean_completion ABC method
- DEC-003/011: 2 new e2e siblings + BQ smoke parametrize
- DEC-008/009: per-provider max_output_tokens floor table (1024/1024/2048)
- DEC-010: pre-release-only cadence (~\$0.30 / suite run)
- DEC-012: apply_provider_override helper

10 stories sized for Ralph contexts. Architecture review: 1 concern (seam
design — resolved), 8 pass. Regression risk green (no fixture pins old
reasoning string; existing test_gemini_neutrality.py:381 already pins the
post-fix shape).

* bd_1-scaffolding-eu0.4: #155 US-003 — bump Gemini live fixture to 2048 + per-provider max_output_tokens floor docs

* bd_1-scaffolding-eu0.5: #155 US-004 — apply_provider_override helper + BQ smoke uses it

Adds the canonical per-test grade-provider overlay helper. Multi-provider
e2e smokes (BigQuery+Anthropic / +OpenAI / +Gemini) share the committed
Austin fixture and swap only grade.provider/model/max_output_tokens via
this seam — no near-duplicate fixtures.

The helper is non-destructive: unset knobs left alone, sibling top-level
blocks (llm:/safety:/prune:) round-trip via yaml.safe_dump(sort_keys=False).
Missing signalforge.yml raises FileNotFoundError rather than silently
creating one (masks misconfigured tests).

Unit-tested in tests/cli/test_e2e_helpers.py — runs in the default
pytest set (no marker), so a regression in the YAML overlay plumbing the
real e2e smokes depend on trips immediately.

BigQuery smoke refactored to call apply_provider_override(project_dir,
grade_provider='anthropic') as a no-op proof-of-use; OpenAI (US-005) and
Gemini (US-006) sibling smokes will pass non-default values through the
same seam.

* bd_1-scaffolding-eu0.2: #155 US-001 — LLMProvider.is_clean_completion ABC + 3 concretes + wire-in

Add provider-neutral allowlist gate for response finish-reason / stop-reason
to prevent silent pass-through of truncated / safety-filtered / tool-use
responses (DEC-001/002/005/006/007 of plans/super/155).

- LLMProvider.is_clean_completion(response) -> bool — abstract
- LLMProvider.unclean_finish_reason_message(response) -> str — default + per-vendor overrides
- AnthropicProvider._CLEAN_STOP_REASONS = {end_turn, stop_sequence}; tool_use is UNCLEAN (DEC-006)
- OpenAIProvider._CLEAN_STOP_REASONS = {stop}
- GeminiProvider._CLEAN_STOP_REASONS = {STOP}
- call_llm wires the gate immediately before strategy.extract_text_blocks,
  raising LLMResponseFormatError (typed, non-retryable response-shape error)
  with the provider-specific diagnostic when the gate returns False.
- _DummyProvider + FakeNoCacheProvider satisfy the new abstract by
  returning True (no finish-reason concept on the canned shapes).

TDD: 4 happy-path tests added (one per concrete provider + 2 for Anthropic
covering both clean stop reasons) and confirmed failing before implementation,
then green. Canonical validation quad (ruff/format/pyright/pytest) all-green;
2560 tests pass (no regressions); AST scans 3/9/10 pass.

* bd_1-scaffolding-eu0.6: #155 US-005 — new tests/cli/test_e2e_openai_smoke.py

Full-pipeline live e2e gated by @pytest.mark.e2e + @pytest.mark.openai
markers and a three-env-var skip gate (SF_RUN_OPENAI=1, OPENAI_API_KEY,
GOOGLE_CLOUD_PROJECT — BigQuery stays the warehouse). Mirrors
tests/cli/test_e2e_bigquery_smoke.py verbatim and only swaps the grader
via apply_provider_override(grade_provider='openai', grade_model='gpt-4o')
per DEC-011/DEC-012 of plans/super/155-gemini-truncation-e2e-gap.md;
drafter stays Anthropic Sonnet per the fixture's llm.model pin and the
cost-table rationale (DEC-009).

Pins the seven invariants from the BQ smoke (DEC-009 of #10): exit 0,
sidecar present, kept+flagged+dropped>=1, always-passes drop present
(warehouse-side, provider-independent), flagged_count>=1 (tight grade
thresholds), GradingReport.aggregate_complete=True (the cross-provider
contract the in-isolation grade smokes can't pin), and no traceback in
stderr (cli-layer.md DEC-016).

Test is deselected by default addopts; maintainer runs once pre-release.

* bd_1-scaffolding-eu0.3: #155 US-002 — per-provider unclean-path tests + call_llm integration (rule edit deferred to orchestrator)

Per-provider unclean-path tests pinning the LLMProvider.is_clean_completion
contract (#155 DEC-001/DEC-002/DEC-005/DEC-006/DEC-007):

- tests/llm/test_anthropic_provider_via_fake.py: + max_tokens (with partial
  text), tool_use, unclean_finish_reason_message naming stop_reason.
- tests/llm/test_openai_provider_via_fake.py: + length (with partial text),
  content_filter, tool_calls, unclean_finish_reason_message naming
  finish_reason.
- tests/llm/test_gemini_provider_via_fake.py: + MAX_TOKENS-with-partial-text
  (the LOAD-BEARING #155 Finding 1 regression pin, with full context comment),
  SAFETY/RECITATION/OTHER parametrized, unclean_finish_reason_message naming
  finish_reason.
- tests/llm/test_client.py: + call_llm integration test asserting
  LLMResponseFormatError raises at the is_clean_completion gate
  (post-messages.create, pre-extract_text_blocks, no retry).

Existing contract pin tests/grade/test_gemini_neutrality.py:381 continues
to pass unmodified — the safety-blocked Gemini path now routes through the
same orchestrator gate as MAX_TOKENS, both landing at
'call failed: GradeLLMError' degrade.

Note: .claude/rules/llm-drafter.md edit deferred — per memory
ralph-worker-claude-dir-perms, .claude/ writes are orchestrator-only and
will land in a separate commit after this merge.

* bd_1-scaffolding-eu0.8: #155 US-007 — parametrize tests/cli/test_e2e_bigquery_smoke.py over grade.provider

Adds @pytest.mark.parametrize over grade_provider ∈ [anthropic, openai,
gemini] to the BigQuery e2e smoke test. Per #155 DEC-003 this covers
the cross-provider diff-sidecar rendering contract the in-isolation
grade smokes (tests/grade/test_*_grade_live.py) cannot pin: those
smokes never exercise the diff-sidecar evidence/reasoning cascade with
a non-Anthropic judge.

Per #155 DEC-011 the drafter stays Anthropic Sonnet across all three
variants (fixture stability — the LLM payload the drafter sees is
unchanged, so the always-passes column the LLM proposes is
reproducibly the same). Only the grader varies, via the canonical
apply_provider_override helper (US-004 / DEC-012).

Per-variant env-var gates layered on top of the existing baseline:
  - anthropic: baseline only (SF_RUN_BQ + ANTHROPIC_API_KEY + GOOGLE_CLOUD_PROJECT)
  - openai:   baseline + SF_RUN_OPENAI + OPENAI_API_KEY
  - gemini:   baseline + SF_RUN_GEMINI + GOOGLE_API_KEY

Gemini variant pins max_output_tokens=2048 per #155 Finding 2 — Gemini
2.5-flash's verbose reasoning field truncates mid-string at the
default 512/1024 floors and would flake assertion #6 (aggregate_complete).

Sibling files (test_e2e_openai_smoke.py / test_e2e_gemini_smoke.py)
remain per DEC-011 for per-provider failure ergonomics and cost
transparency; this parametrize is internal to the BQ smoke.

Pytest IDs: test_*[anthropic] / test_*[openai] / test_*[gemini]. All
three are deselected by default addopts (gated by the e2e marker);
the maintainer runs them per pre-release live suite (US-008).

Validation: uv sync --dev && ruff check && ruff format --check &&
pyright && pytest — all green (2566 passed, 69 deselected, coverage
97.40%).

* bd_1-scaffolding-eu0.3: #155 US-002 (orchestrator portion) — clarify llm-drafter.md DEC-005 for the is_clean_completion seam

Updates the Gemini-section DEC-005 contract to reflect the post-#155 generalisation:
- Rule now applies to ALL providers (Anthropic stop_reason, OpenAI choices[0].finish_reason,
  Gemini candidates[0].finish_reason.name) — not just Gemini
- Enforcement moved from "no text at all" check buried in extract_text_blocks to the new
  LLMProvider.is_clean_completion(response) -> bool ABC method (#155 DEC-005)
- Closes the Finding-1 gap: MAX_TOKENS with partial text now surfaces as
  LLMResponseFormatError → GradeLLMError, not GradeOutputError(json_parse)
- Per-provider _CLEAN_STOP_REASONS enumerated; tool_use deliberately UNCLEAN per DEC-006
- unclean_finish_reason_message override (DEC-007) keeps vendor-native field names visible

Test-side pins (worker portion of US-002, commit 9a23e3f):
- tests/llm/test_{anthropic,openai,gemini}_provider_via_fake.py — unclean-path coverage
- tests/llm/test_client.py — call_llm gate integration

Worker (commit 9a23e3f) deferred this rule edit per memory ralph-worker-claude-dir-perms;
this commit closes the bead's orchestrator-only deliverable.

* bd_1-scaffolding-eu0.9: #155 US-008 — CONTRIBUTING.md live-suite pre-release cadence + env-var block

Add a 'Live e2e suite (pre-release only)' subsection to CONTRIBUTING.md
per DEC-010 of plans/super/155-gemini-truncation-e2e-gap.md.

Documents the full pre-release maintainer audit:
- 5 paid e2e tests (BQ smoke parametrized over 3 grader providers per
  US-007, OpenAI sibling, Gemini sibling with max_output_tokens=2048
  floor per DEC-008, Snowflake sibling)
- 6 grade-only / draft-only live-API smokes gated by anthropic /
  openai / gemini markers
- One-shot invocation with -m 'e2e or anthropic or openai or gemini'
  --no-cov and the full env-var stack (SF_RUN_*, ANTHROPIC_API_KEY,
  OPENAI_API_KEY, GOOGLE_API_KEY, GOOGLE_CLOUD_PROJECT, SNOWFLAKE_*)

Frames the cadence as pre-release only — NOT per-PR, NOT CI-gated. The
addopts exclusion in pyproject.toml already keeps these out of default
runs; this section just documents the maintainer-side invocation when
cutting a release. Cost ceiling: ~$0.30/run × ~2–3 audits/month =
~$0.60–1.00/month.

* bd_1-scaffolding-eu0.10: #155 US-009 — Quality Gate fixes (4-pass code review)

Pass 1 (correctness): 0 real bugs. 2 doc-drift fixes:
- docs/grade-ops.md floor table: pre-fix GradeOutputError narrative
  rewritten to post-fix LLMResponseFormatError → GradeLLMError per #155 DEC-005
- tests/cli/test_e2e_gemini_smoke.py invariant-#6 comment: same update

Pass 2 (simplification): 0 refactors needed.

Pass 3 (test coverage): 0 critical gaps. 3 nice-to-have safety nets added:
- tests/llm/test_gemini_provider_via_fake.py — new orchestrator wire-in pin
  for MAX_TOKENS+partial-text via call_llm (distinct from existing
  SAFETY-only call_llm test)
- tests/llm/test_openai_provider_via_fake.py — new orchestrator wire-in pin
  for length+partial-text via call_llm (no prior call_llm coverage)
- tests/grade/test_gemini_neutrality.py:381 — docstring comment binding the
  existing safety-blocked pin to the new #155 MAX_TOKENS routing path

Pass 4 (rules compliance): 1 real rule violation + 1 multi-surface drift
(same root cause). Fixed:
- tests/cli/test_e2e_openai_smoke.py::_skip_reason() expanded from 3 to 5
  env-var checks (was missing SF_RUN_BQ + ANTHROPIC_API_KEY despite the
  drafter staying Anthropic per DEC-011); mirrors the Gemini sibling and
  the parametrized BQ smoke. Module docstring + CONTRIBUTING.md entry
  updated in lockstep.

CodeRabbit: skipped (no MCP integration available in this environment;
the project's user-triggered /code-review ultra is the cloud-billed path
operators run separately).

Final canonical validation: 2581 passed, 0 ruff/pyright errors, 97.47%
coverage, mkdocs build clean (existing cross-repo-link warnings only,
intentional per docs-publishing.md).

* bd_1-scaffolding-eu0.11: #155 US-010 — Patterns & Memory

Captures three durable lessons from #155 in the rule set + memory:

1. `.claude/rules/llm-drafter.md` § "Provider-neutral seam (#135)" — the
   `LLMProvider` ABC bullet now lists `is_clean_completion` +
   `unclean_finish_reason_message` alongside the rest of the abstract
   methods, cross-referencing the Gemini-shape § for the full contract
   + the `_CLEAN_STOP_REASONS` convention each concrete declares. This
   is the discoverability seam — a future provider implementer reading
   the abstraction-level section sees the gate immediately.

2. `.claude/rules/testing-signal.md` § "End-to-end gated tests (issue #10)"
   — new subsection "Per-test provider overlay via apply_provider_override"
   (DEC-012). Documents the canonical helper for per-test grade-provider
   overlays + the load-bearing 5-env-var contract (drafter Anthropic +
   grader-provider stays a 5-var gate even when the grader varies; the
   3-var docstring drift in test_e2e_openai_smoke.py was QG Pass 4's
   real finding).

3. Memory: new `in-isolation-smoke-misses-pipeline-drift.md` —
   in-isolation grade-only smoke tests can pass while a structural
   contract regression slips; a new provider needs a full-pipeline
   `signalforge generate` e2e too. Distinct from the existing
   `fake-driven-byte-identity-blind-spot` (that lesson is about
   fake-call-shape vs real-call-shape; this is about isolation-scope
   vs pipeline-scope coverage). MEMORY.md index updated.

ORCHESTRATOR-only commit per memory `ralph-worker-claude-dir-perms`
(workers can't write to .claude/).

* #155 US-009 follow-up: close codecov patch-coverage gap (7 uncovered lines → 0)

Codecov flagged patch coverage at 86.54% (7 lines missing in providers.py)
— the defensive-raise arms in is_clean_completion + the ABC default
unclean_finish_reason_message body. Pass 3 of QG already identified these
as nice-to-have safety nets and I deferred them; codecov on PR #156
called them out, so adding them now to close the gap.

Files:
- tests/llm/test_anthropic_provider_via_fake.py — defensive test:
  missing stop_reason attribute raises LLMResponseFormatError
- tests/llm/test_openai_provider_via_fake.py — two defensive tests:
  missing/empty choices raises; missing finish_reason on first choice raises
- tests/llm/test_gemini_provider_via_fake.py — two defensive tests:
  missing/empty candidates raises; missing finish_reason on first candidate raises
- tests/llm/test_providers.py — ABC default unclean_finish_reason_message
  test via _DummyProvider (inherits the default unchanged)

These guard against future SDK shape regressions (e.g. a vendor renames
stop_reason → terminated_for; without these arms the conservative-degrade
path silently swallows the structural surprise). Pinned at unit cost so
the regression surfaces at unit-test time, not live-e2e time.

Validation: 2587 passed (+6), 0 ruff/pyright errors, providers.py coverage
295/3 missing (only the pre-existing _count_openai_tokens defensive lines
from #136 remain — out of this PR's patch scope), total coverage 97.57%.

* #155: Address PR review feedback (CodeRabbit + Copilot, 0 false positives)

3 real findings across reviewers, 8 sites fixed:

CodeRabbit (2 inline): test_call_llm_{gemini,openai}_..._is_clean_gate
tests added in QG Pass 3 were missing @pytest.mark.unit + @pytest.mark.llm,
so marker-scoped runs (`pytest -m "unit and llm"`) would silently skip
the orchestrator-level regression pins. Sibling tests in the same files
all use the unit+llm marker pair.

Copilot (1 inline on tests/cli/test_e2e_gemini_smoke.py:31): docstring
header still said "Gated by THREE env vars" with an awkward "Note:
ANTHROPIC_API_KEY is also required" follow-on — but `_skip_reason()`
actually checks FIVE. Mirrors the OpenAI-sibling drift QG Pass 4
already caught (`.claude/rules/testing-signal.md:169`). Rewrote the
header to enumerate all five gates upfront with the same DEC-011
drafter-stays-Anthropic framing the OpenAI sibling uses post-QG.

In addition: applied the same `@pytest.mark.unit + @pytest.mark.llm`
fix to the 6 defensive-raise tests + the ABC default test from the
codecov follow-up commit (`ce7e050`) — same root cause, all sibling
tests in the same files use the marker pair, only my additions lacked it.

Validation: 2587 passed (unchanged), 0 ruff/pyright errors. Marker-scoped
collection (`pytest -m "unit and llm" --collect-only`) now includes all
8 newly-marked tests.

…e2e floor to 4096 (#160)

* fix(#158): surface Gemini finish_reason in degrade reasoning + raise e2e floor to 4096

Two fixes from the post-#155 full-pipeline finding (#158):

1. **Diagnostic upgrade (`signalforge.grade.engine`).** Add
   `_format_degrade_reasoning(exc)` helper. When the wrapped cause is
   `LLMResponseFormatError`, surface its bare `message` (which names
   the vendor `finish_reason` field + value via
   `LLMProvider.unclean_finish_reason_message`) into the degraded
   `GradingResult.reasoning` — e.g.
   `"call failed: GradeLLMError: Gemini response did not finish with
   a clean stop reason (finish_reason='MAX_TOKENS')..."` instead of
   the bare `"call failed: GradeLLMError"`. For every other cause
   (auth / rate-limit / parser / budget) the existing class-name
   shape is preserved verbatim so the audit corpus stays diff-clean
   for the 90% case — only the response-shape branch grows the
   diagnostic. Two new unit tests pin the new + preserved shapes.

2. **Floor bump (e2e overlay).** Raise `grade_max_output_tokens`
   overlay from 2048 to 4096 in both `test_e2e_gemini_smoke.py` and
   the `[gemini]` parametrization of `test_e2e_bigquery_smoke.py`.
   The 2048 figure was the in-isolation 5-pair smoke floor verified
   in #155 DEC-008; the first full-pipeline run found 5–6/108 pairs
   still degrade at 2048 (Gemini's per-pair `reasoning` length is
   high-variance enough that the in-isolation floor is not the
   full-fixture floor). 4096 is the new #158 fixture-scale floor.

Doc reframes in lockstep:
- `docs/grade-ops.md` + `docs/draft-ops.md` — Gemini row of the
  recommended-floors table bumped 2048 → 4096, with a
  "fixture-scale caveat" callout explaining the floor is necessary
  but not sufficient and operators should watch
  `aggregate_complete` on their own fixture.
- `plans/super/155-...md` DEC-008 — addendum reframing the 2048
  "verified safe" claim as scoped to the in-isolation probe; the
  DEC stays as historical record of the 2048 figure's provenance.

Existing `test_grade_artifacts_safety_blocked_response_degrades_pair`
updated to assert the new `startswith("call failed: GradeLLMError: ")`
+ `"finish_reason='SAFETY'" in reasoning` shape rather than the bare
class name — the contract pin moves with the broadened reasoning.

The acceptance gate from #158 (full-fixture e2e against Gemini
returning `aggregate_complete=True`) is only verified by re-running
`tests/cli/test_e2e_bigquery_smoke.py[gemini]` + `test_e2e_gemini_smoke.py`
under the live env-var stack (`SF_RUN_GEMINI=1 GOOGLE_API_KEY=…
SF_RUN_BQ=1 ANTHROPIC_API_KEY=… GOOGLE_CLOUD_PROJECT=… uv run pytest -m
"e2e and gemini" --no-cov`) — those are excluded from default CI.
Local 2589-test suite + ruff + pyright clean.

Beads: bd_1-scaffolding-we0 (diagnostic), bd_1-scaffolding-ila (floor).

Closes #158.

* #158: address PR review (Copilot + CodeRabbit)

Four review-feedback fixes, all real:

1. `docs/grade-ops.md` (Copilot l.599): the safety-filter handling
   prose still pointed at `GeminiProvider.extract_text_blocks` as
   the raise site, but post-#155 the provider-neutral
   `LLMProvider.is_clean_completion` gate in `call_llm` is the
   primary raise site — and it fires on partial-text MAX_TOKENS too,
   not just zero-text-parts. Reworded to name both paths and route
   them through the same conservative-degrade contract.

2. `docs/draft-ops.md` (Copilot l.595): the Gemini drafter floor
   row leaned on grader-side evidence (#158) while the section
   lead-in says floors are "from live drafting runs." Qualified the
   4096 figure as a *conservative mirror* of the grader floor,
   explicitly flagged as pending Gemini-drafter live validation
   when that lands.

3. `plans/super/155-...md` DEC-008 (Copilot l.56): the #158
   addendum carried a broken-sentence placeholder
   ("See `plans/super/155-...` was the in-isolation verification"
   — typo from a half-edit). Replaced with a concrete pointer to
   issue #158 + the durable lesson in memory
   `in-isolation-smoke-misses-pipeline-drift`.

4. `tests/cli/test_e2e_gemini_smoke.py:69` (CodeRabbit outside-diff):
   module-docstring invariant #6 still said "the 2048 cap fixes the
   truncation bug" — stale after the floor bump. Now says "the 4096
   cap (#158) fixes the full-fixture truncation bug."

No code changes (doc + docstring only). Full local validation
(ruff + pyright + 2589 pytest) clean.

* #159: drafter column-type awareness (plan)

Plan for closing the test_e2e_business_rules flake where the drafter
emits type-incoherent custom_sql (INT64 vs STRING comparison), prune
correctly routes to kept-without-evidence, and the test asserts
kept-with-evidence.

Root cause: tests/fixtures/dbt_project_austin/target/manifest.json
carries data_type: null for every column. The drafter / safety /
prompt pipeline already supports types end-to-end — the gap is
upstream.

Scope (DEC-001): A + B + D.
  A. populate data_type in the Austin fixture
  B. merge target/catalog.json types into Column.data_type at load time
  D. add sqlglot AST type-coherence check in _validate_anchor_contract

13 decisions captured (DEC-001 … DEC-013). 4 implementation stories
+ Quality Gate + Patterns & Memory. No new CLI flag, no new config
knob, no _PROMPT_VERSION rotation, no new error class — fix lives
inside existing extensibility seams.

* bd_1-scaffolding-crh.1: manifest loader — catalog.json sibling merge for Column.data_type (#159)

Implements US-001 of the #159 plan (DEC-001, DEC-002, DEC-007, DEC-010).

The manifest loader now reads a sibling 'target/catalog.json' when present
and overlays its per-column 'type' onto Column.data_type via the frozen-model
'model_copy(update={...})' pattern. Case-insensitive column matching covers
Snowflake (uppercased identifiers) and BigQuery (preserved-case) catalogs.
Missing / malformed / unreadable catalog → silent no-op (stage-0 invariant);
phantom columns are dropped; manifest columns absent from the catalog keep
data_type=None. The catalog path is canonicalised through
signalforge._common.path_safety.canonicalise_path, so a symlink escape
raises PathContainmentError (security gate is NOT in the silent-degrade set).

Tests: 19 new cases under tests/manifest/test_loader.py covering the 8
TDD acceptance cases plus parametrised shape-degrade guards. Fixtures
under tests/fixtures/manifest/ (canonical/case-mismatch/phantom/partial
catalogs + a minimal manifest carrying three columns).

* bd_1-scaffolding-crh.2: drafter parser — sqlglot type-coherence defence for custom_sql (#159)

Add a sqlglot-based type-coherence check to _validate_anchor_contract
in signalforge.draft.parser. For each custom_sql test, parse the SQL
with sqlglot.parse_one(dialect=...), annotate types, and append
violations for direct Column <op> Column comparisons where both
known types are incompatible. Skip silently on every other shape
per DEC-006 (Cast / SafeCast / Coalesce / function call / subquery
/ literal / NULL / window / unparseable SQL / unknown types).

A {{ this }} / {{ ref(...) }} placeholder is substituted with a
stable identifier before parsing so sqlglot can read the surrounding
SQL — the parser defence runs pre-resolution and the LLM almost
always references the model via Jinja.

Bidirectional COERCES_TO compatibility lets numeric-family coercions
(INT64↔FLOAT64, NUMERIC↔BIGNUMERIC) pass while INT64 vs STRING /
DATE is flagged. Type violations append to the existing
LLMOutputAnchorContractError.violations list (DEC-011) — no new
error subclass.

parse_draft_response gains two keyword-only params:
  - model_columns_by_type: Mapping[str, str | None] | None = None
  - dialect_name: str = 'bigquery'

draft_from_request builds the type map from model.columns_list and
threads through; v0.1 hard-codes 'bigquery' with a TODO referencing
v0.2 multi-warehouse work (DEC-013).

sqlglot promoted to a direct runtime dep (sqlglot>=30,<31) in
[project].dependencies + [project.optional-dependencies].dev +
[dependency-groups].dev (mirror per python-build.md). Previously a
dev-only transitive via fakesnow; type-defence correctness is
load-bearing.

Confinement: sqlglot imports live ONLY in src/signalforge/draft/parser.py
(DEC-008). Convention only in v0.1; no AST scan.

Traces to DEC-001 / DEC-003 / DEC-005 / DEC-006 / DEC-008 / DEC-011
/ DEC-012 / DEC-013 in plans/super/159-drafter-column-types.md.

17 new tests in tests/draft/test_parser.py:
  - 3 planted positives (int64 vs string × 2 ops, int64 vs date)
  - 9 planted negatives (numeric coercion × 2, cast / safe_cast /
    coalesce / null / literal / function / subquery)
  - 5 robustness (unparseable, both-unknown, partial-unknown,
    None-map-skips-arm, collect-all-with-structural-violation)

All 41 tests in tests/draft/test_parser.py pass; full canonical
validation (ruff check + ruff format + pyright + pytest) green
with 2604 tests passing and 97.44% coverage.

* bd_1-scaffolding-crh.3: Austin fixture — populate data_type + add catalog.json (#159)

Populate real BigQuery data_type values on every column of
stg_bikeshare_trips in the Austin manifest fixture and ship a
sibling target/catalog.json with the same types so US-001's
catalog-merge read-path is exercised end-to-end by the e2e smoke.

Types verified via 'bq show --schema bigquery-public-data:austin_bikeshare.bikeshare_trips':
  - trip_id, subscriber_type, bike_id, end_station_id  STRING
  - start_time                                          TIMESTAMP
  - start_station_id, duration_minutes                  INT64

end_station_id is STRING but start_station_id is INT64 — exactly
the type mismatch the original #159 BQ error
'No matching signature for operator != for argument types: INT64, STRING'
flagged in the production prune.jsonl.

DEC-008 of #47 (demo-fixture parity) requires the shipped
src/signalforge/_demo/ tree stay byte-equal to the e2e fixture
except for the two documented rewrites; both manifest.json and
the new catalog.json are mirrored into _demo/target/ in lockstep.

Traces to DEC-001 sub-option A + DEC-004 in plans/super/159-drafter-column-types.md.

* bd_1-scaffolding-crh.4: 5-surface rules + docs for column-type awareness (#159)

Documents the two new behaviours added in US-001 (catalog.json sibling merge)
and US-002 (sqlglot parser type-coherence defence), per cli-layer.md
"Multi-surface parity for behaviour changes".

Surfaces touched:
- .claude/rules/manifest-readers.md — new "Catalog.json sibling merge"
  section: 5 load-bearing rules, no _PROMPT_VERSION rotation rationale,
  no drift detector required.
- .claude/rules/llm-drafter.md — new "Sqlglot type-coherence check"
  subsection under "Whole-draft fail-loud anchor contract": dual-defence
  framing (prompt + parser), 6 load-bearing rules incl. skip-when-uncertain
  + Jinja substitution + ParseError silent skip + sqlglot confinement.
- docs/manifest-loader-ops.md — operator-facing "Column types from
  catalog.json" section: how to run dbt docs generate, failure modes
  (all silent), refresh notes.
- docs/draft-ops.md — operator-facing "Type-coherence defence" section
  inserted after "Hard JSON validation + anchor-contract": what it
  catches, what it skips, threading API, dialect support, dep note.
- CHANGELOG.md — one Added entry (catalog.json merge), one Fixed entry
  (sqlglot parser defence).

Validation: ruff/format/pyright/pytest all green; 2623 passed,
97.46% coverage.

* bd_1-scaffolding-crh.5: Quality Gate — doc/code mismatch fix (#159)

QG review pass 1 (low effort) surfaced one finding: docs/draft-ops.md
§ "Type-coherence defence" claimed the check covers "plus IN-list
comparisons" but parser.py:_check_custom_sql_type_coherence only
matches (EQ, NEQ, GT, LT, GTE, LTE) — no exp.In handler. Per DEC-006
skip-when-uncertain, removing the IN claim is the right fix (matches
actual conservative behaviour); adding IN handling is deferred to a
follow-up if real-world drift demands it.

Passes 2 (medium), 3 (high), and 4 (max) review surfaced no
additional real-bug findings. The implementation honors all 13 #159
DECs:
- DEC-008 sqlglot confined to signalforge.draft.parser (grep verified)
- DEC-006 skip-when-uncertain (Cast/SafeCast/Coalesce/IfNull/function/
  subquery/literal/NULL/window/unknown-type/parse-error all skip)
- DEC-009 no _PROMPT_VERSION rotation
- DEC-011 violations append to existing LLMOutputAnchorContractError
- DEC-012/013 model_columns_by_type + dialect_name kwargs threaded
- DEC-002/007/010 catalog.json sibling lookup, case-insensitive,
  silent degradation

CodeRabbit skill not registered in this session; manual review only.

Canonical validation green: ruff/format/pyright all clean; pytest
2623 passed, 97.46% coverage.

* bd_1-scaffolding-crh.5: cover defensive branches in parser type-coherence (#159)

Codecov flagged 11 missing patch-coverage lines in src/signalforge/draft/
parser.py — all in `_check_custom_sql_type_coherence` and its
model-level call site:

- 121: `_types_compatible` `a == b` short-circuit (same-type case)
- 126: reverse-direction `a in COERCES_TO[b]` branch
- 168-171: defensive `except sqlglot.errors.SqlglotError` (non-ParseError)
- 174: `if parsed is None: return ()` (parse_one can return None)
- 184-187: defensive `except Exception` around `annotate_types`
- 209-210: defensive `except Exception` around `DataType.build`
- 353-354: model-level custom_sql type-coherence call site

Per memory `qg-pass-3-defer-defensive-tests-fails-codecov` ("if a Pass-3
nice-to-have covers lines inside the patch diff, upgrade it to must-fix;
codecov holds patch coverage to project standard regardless"), these
defensive branches need explicit tests rather than skipping them.

7 new tests pin each branch:
- test_custom_sql_same_type_comparison_skipped (121)
- test_custom_sql_reverse_coerce_direction_accepted (126)
- test_check_custom_sql_type_coherence_sqlglot_non_parse_error_skipped (168-171, monkeypatch)
- test_check_custom_sql_type_coherence_parser_returns_none_handled (174, monkeypatch — parse_one returning None varies by sqlglot release)
- test_check_custom_sql_type_coherence_annotate_types_failure_skipped (184-187, monkeypatch)
- test_custom_sql_invalid_type_string_skipped (209-210, opaque type string)
- test_model_level_custom_sql_type_mismatch_is_rejected (353-354)

Mix of organic-input tests where possible (lines 121/126/209-210/353-354)
and monkeypatch tests for the sqlglot-internals defensive catches that
can't be triggered organically without mocking (168-171/174/184-187).

Imports the private `_check_custom_sql_type_coherence` helper alongside
`_LLMResultMeta` per the existing pattern (private-under-test).

Result: parser.py at 100% coverage (was 92% / 11 missing). Full project
coverage up to 97.61% (from 97.46%). 2630 tests pass (+7).

* bd_1-scaffolding-crh.5: cover pre-existing defensive gaps in loader+schema (#159)

Codecov flags any uncovered line in a file modified by the PR — even
pre-existing defensive branches that #159 never touched. The catalog
overlay landed in loader.py and the type-coherence kwargs threaded into
schema.py, so both files surfaced their pre-existing gaps on the PR
view. Closing those completes the project-coverage picture for #159.

schema.py (2 lines):
- test_draft_from_request_record_too_large_propagates_typed (line 250):
  pin that LLMResponseAuditRecordTooLargeError raised by write_response_
  event is re-raised as-is, NOT wrapped under LLMResponseAuditWriteError
- test_draft_from_request_keyboard_interrupt_propagates_untouched (line
  254): pin that a Ctrl-C signal mid-audit-write propagates with its
  identity intact — never silently demoted to an audit error

loader.py (6 lines):
- test_load_project_dir_is_a_file_raises_manifest_not_found (line 231):
  non-directory project_dir → ManifestNotFoundError (distinct from
  FileNotFoundError caught one branch up)
- test_load_non_dict_metadata_raises_manifest_error (line 283): manifest
  with metadata as a non-dict → ManifestError before version-sniff
- test_load_disabled_with_non_list_value_continues (line 308): defensive
  shape-drift skip in the disabled-models loop
- test_schema_version_non_string_returns_empty_string (line 485): the
  free-function schema_version() returns "" for a non-string version
- test_get_model_resolver_index_cache_hit_returns_cached (line 598): the
  in-memory resolver-index cache is reused on second get_model call
- test_get_model_by_file_path_for_disabled_model_raises_disabled (line
  679): file-path lookup for disabled model raises ModelDisabledError
  (the path-lookup branch needs the same disabled detection the
  unique_id branch already has)

Result:
- src/signalforge/draft/parser.py:   100% (was 100%)
- src/signalforge/draft/schema.py:   100% (was 96%, 2 missing)
- src/signalforge/manifest/loader.py: 100% (was 97%, 6 missing)
- Project coverage: 97.72% (was 97.61%)
- 2638 tests pass (+8)

Per memory `qg-pass-3-defer-defensive-tests-fails-codecov`. Most tests
use monkeypatch or carefully-crafted JSON fixtures to hit the precise
defensive branch; lines that can be exercised organically (231, 283,
598, 679) use real Manifest construction.

* #159: address PR #161 review feedback (5 threads)

Addresses all 5 unresolved review comments on PR #161:

Thread 1 (CodeRabbit, plan US-003 "Done when"):
- Rewrote the criterion to be story-local: scopes only THIS story's own
  commit, not the cumulative diff against the base branch. Adds the demo
  mirror files explicitly (the DEC-008 of #47 parity gate the original
  scope missed). Clarifies why US-001 + US-002 are real dependencies.

Thread 2 (CodeRabbit, duplicate "Beads manifest" heading):
- Already fixed during devolve (Phase 7 cleanup committed earlier);
  only one heading remains at line 302. No code change.

Thread 3 (Copilot, test_loader.py Windows skipif chain):
- `@pytest.mark.skipif(os.geteuid() == 0, ...)` ran at collection time
  on Windows even when the prior `sys.platform == "win32"` skipif fired,
  because pytest evaluates ALL skipif predicates. On Windows os.geteuid
  doesn't exist → AttributeError breaking collection. Combined into a
  single skipif with `hasattr(os, "geteuid")` short-circuit.

Thread 4 (Copilot, docs/manifest-loader-ops.md "all silent" framing):
- Added the path-containment caveat: catalog.json that escapes the
  project via symlink raises PathContainmentError loud — the one
  non-silent failure mode. Reworded section header from "all silent"
  to "all silent except the path-safety gate".

Thread 5 (Copilot, CHANGELOG mechanism wording):
- The previous wording implied sqlglot's annotator received a `schema=`
  kwarg. The actual mechanism walks binary comparison nodes and looks
  each operand's column name up in the model's data_type map directly,
  then tests via TypeAnnotator.COERCES_TO. Reworded to match.

Validation: ruff + format + pyright + pytest all green; 2638 tests pass,
97.72% coverage. No production-code changes (docs / plan / test
decorator only).

* #157: super plan — e2e cost docs + parallelization (plan)

Scope: both ticket asks together. Adds a re-runnable cost-rollup helper
(`signalforge.llm.cost.rollup_audit_dir`) + a `scripts/measure_e2e_cost.py`
wrapper, adds `pytest-xdist` as an opt-in dev dep (no addopts change), then
lifts the measured baseline into the three drifted doc surfaces
(plans/super/155-…md DEC-010, CONTRIBUTING.md § Live e2e suite, docs/grade-ops.md
§ Cost guidance).

6 implementation stories + Quality Gate + Patterns & Memory. US-005 is
maintainer-only (live re-run + measurement capture); the rest are
Ralph-eligible.

* #157: devolve plan to beads

Epic bd_1-scaffolding-e1a + 8 children with deps wired.
US-005 (maintainer live re-run) assigned to @wjduenow.
Phase: devolved.

Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

* bd_1-scaffolding-e1a.1: scaffold signalforge.llm.cost subpackage

Adds CostError(LLMError) base + 3 concrete errors (audit-missing,
malformed-record, unknown-model); registers each at CLI tier 2
and CostError as a dual-registration safety-net + excluded base.
Ships frozen-dataclass shapes (CostReport / ProviderRollup /
ModelRollup); rollup_audit_dir() is a NotImplementedError stub
that US-002 fills in. Extends scan-7 to depth-2 glob; bumps
expected per-stage errors.py count 11 → 12.

Refs #157.

Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

* bd_1-scaffolding-e1a.2: implement signalforge.llm.cost.rollup_audit_dir

Walks .signalforge/llm_responses.jsonl + grade.jsonl under a
canonicalised project_dir, deserialises each record via the
existing LLMResponseEvent / GradeEvent models, and aggregates
per-provider per-model USD against the frozen PRICES table.
Symlink-hardened path entry; typed errors for missing audit,
malformed record, unknown model. Degraded report when only
one JSONL present; CostRollupAuditMissingError when neither.

16 TDD cases (test_rollup_*) cover provider mixes, error paths,
path safety, and the frozen-dataclass invariants.

* bd_1-scaffolding-e1a.3: add scripts/measure_e2e_cost.py wrapper

Thin argparse entrypoint around signalforge.llm.cost.rollup_audit_dir.
--format {text,json} controls output shape; CostError -> exit 2 via
the boundary catch; no Traceback ever leaks to stderr (cli-layer.md
floor). scripts/ stays repo-only -- the wheel_smoke gate asserts it
is excluded from the built wheel.

* bd_1-scaffolding-e1a.4: pytest-xdist dev dep + parallel e2e docs

Adds pytest-xdist as an opt-in dev dep (both [dependency-groups].dev
and [project.optional-dependencies].dev, mirrored). Rewrites
CONTRIBUTING § "Live e2e suite (pre-release only)" to document
`pytest -m e2e -n 3 --no-cov` as the recommended invocation with
the Anthropic 50-RPM rate-limit caveat + downgrade path. Lists
all 5 paid e2e files (adds test_e2e_business_rules.py — latent
doc gap). Notes cli_subprocess / wheel_smoke stay serial. Adds
parity gate test that asserts every e2e file basename + the
parallel invocation + the rate-limit caveat phrase + the
measure_e2e_cost.py pointer appear in CONTRIBUTING. No addopts
change. Cost figures left stale; US-006 lifts the measured
baseline after US-005's live re-run.

* bd_1-scaffolding-e1a.5: US-005 measured baseline — live e2e run 2026-05-29

`-n 3` wall-clock 14:53 (vs 39 min serial = 2.6× speedup). Grand total
$1.38 / full-suite at PRICE_TABLE_VERSION=2026-05-28 (vs the stale
$0.30 figure). Zero Anthropic rate-limit retries observed; no -n
downgrade needed. Per-test + per-provider rollup tables added to the
plan's refinement log; US-006 lifts these into the 3 user-facing
doc surfaces.

Pre-existing flake observed in test_e2e_business_rules.py
(custom_sql LLM-determinism); rollup unaffected.

* bd_1-scaffolding-e1a.6: lift measured baseline into 3 doc surfaces

Replaces the stale $0.30/full-suite figure across
plans/super/155-...md DEC-010 + the architecture-review row,
CONTRIBUTING.md § "Live e2e suite", and docs/grade-ops.md
§ Cost guidance. New 3-row per-provider table in grade-ops:
Anthropic ~$0.38/model, OpenAI ~$0.21, Gemini ~$0.045.
Each surface carries the date-stamp + PRICE_TABLE_VERSION +
"calibration signal, not a billing guarantee" framing.

Parity gate extended to pin 2026-05-28 across all three
surfaces; planted-violation self-check passes.

* bd_1-scaffolding-e1a.7: Quality gate — fix bugs from code review

Four code-review passes ran against the cbcaeec..HEAD diff (2389 LOC,
18 files). Pass 1 (correctness) found zero bugs. Passes 2/3/4 surfaced
2 real bugs + multiple test-signal / coverage / parity-gate gaps inside
the patch diff. CodeRabbit not invoked (no skill available in this
environment); auto-review will pick up the PR.

Fixes applied:

Pass-2 F1 (BUG): test_rollup_grand_total_equals_sum_of_provider_subtotals
  re-derived the sum the same way the engine does → tautology. Now
  asserts hand-computed $10.50 / $15.00 / $0.90 / $26.40 against the
  locked PRICES table.

Pass-2 F2 (BUG): scripts/measure_e2e_cost.py panic-path (exit 1) was
  untested. New test_measure_e2e_cost_main_exits_1_on_unexpected_error
  monkeypatches rollup_audit_dir to raise ValueError; asserts exit 1
  + "ERROR: ValueError" in stderr + no traceback.

Pass-2 F3: audit_files_consumed asserted as set → now tuple, pins the
  drafter-then-grader ordering invariant.

Pass-2 F4: rate-limit caveat anchored on common words ("Anthropic" +
  "rate limit") → now pinned to verbatim "Anthropic 50 RPM
  rate-limit caveat" (the unique compound phrase).

Pass-2 F5: degraded-report tests skipped USD assertion → both now
  hand-compute $0.0105 for the 1000/500-token claude-sonnet-4-6
  record.

Pass-3 F1 (BUG/coverage): no-prefix-match unknown-model branch in
  _ingest_jsonl was unreachable. New
  test_rollup_unknown_provider_prefix_raises_typed_error covers
  databricks-llama-3-70b-shape model ids.

Pass-3 F3: line_num literal-file-position invariant pinned via
  test_rollup_line_num_reflects_literal_file_position_with_blank_lines
  (blank lines 2-3, malformed on line 4, asserts line_num == 4).

Pass-3 F4: no opus-tier coverage → new
  test_rollup_anthropic_opus_uses_opus_pricing_not_sonnet
  hand-computes $52.50 (5× sonnet's $10.50 for the same token shape)
  so a wrong-tier wire-formula bug fails loud.

Pass-3 F5: empty-providers _print_text branch untested → new
  test_measure_e2e_cost_format_text_no_priced_records_still_prints_total
  asserts both "(no priced records" and "TOTAL: $0.0000" appear.

Pass-3 F7: --format=json audit_files_consumed ordering deterministic-
  by-accident → now pinned to ["llm_responses.jsonl", "grade.jsonl"]
  in the JSON test.

Pass-4 F1 (BUG): _PARALLEL_INVOCATION substring-matched in CONTRIBUTING,
  but the same string appears in two distinct spots (canonical
  recommendation + monitoring example). A partial rotation would
  silently pass. Now asserts the count is exactly
  _PARALLEL_INVOCATION_EXPECTED_COUNT (= 2).

Pass-4 F4 prose: per-test vs per-provider rollup sums could read
  confusingly → added one-line clarifier "Sums agree to rounding:
  per-test sum = $1.3790; per-provider sum = $1.3788; headline = $1.38."

Pass-4 F5 prose: leader-test attribution "gemini_smoke on gw2" was
  undersourced → softened to "gw2 worker's first test (Gemini-grader
  sibling, inferred from progress output)".

Pass-4 F6 prose: plan-157 flake call-out didn't backref #163 →
  added explicit link to issue #163 with the observed-SQL summary.

Canonical validation: 2634 passed (+4 new test cases), pyright 0/0/0,
ruff clean, format clean, coverage 97.59%.

* #157: Address PR review feedback

5 issues from CodeRabbit + Copilot inline reviews on PR #162:

1. CONTRIBUTING.md L152 (Copilot): Gemini e2e said
   `grade.max_output_tokens=2048` but the actual test uses 4096 (the
   #158 floor bump after the full-Austin-fixture e2e found 5-6/108
   pairs still degrading at 2048). Fixed to 4096 with the historical
   2048→4096 context.

2. CONTRIBUTING.md L252+266 (Copilot + CodeRabbit): contradictory
   marker guidance for the Snowflake live tier. Line 157 (my US-004
   doc) said `@pytest.mark.snowflake` (correct — the test file
   confirms); line 266 (pre-existing, stale) said "reached via the
   `e2e` marker" (wrong). The "Full pre-release invocation" example
   silently dropped Snowflake by listing only `e2e or anthropic or
   openai or gemini`. Aligned both: added ` or snowflake` to the
   example expression and rewrote the trailing prose to describe the
   `snowflake` marker's two tiers (offline fakesnow + sqlglot AND
   live warehouse) with the `SF_RUN_SNOWFLAKE=1` opt-in story.

3. src/signalforge/llm/cost/errors.py L75 (Copilot):
   `CostRollupAuditMissingError` built the audit-root display as
   `_format_value(project_dir) + '/' + _format_value(audit_dir)`,
   which renders as two separately-quoted reprs (e.g.
   `'/tmp/proj'/'.signalforge'`). Now formats the combined path
   first, then passes through `_format_value` once — single
   quoted, copy-pasteable.

4. src/signalforge/llm/cost/_rollup.py L122 (Copilot): used
   `assert` for the import-time pricing/provider sanity check,
   which `python -O` strips. The check is load-bearing for
   provider-dispatch correctness — a missing prefix would silently
   route the SKU to CostRollupUnknownModelError at rollup time
   instead of failing loud at import. Replaced with an explicit
   `if/raise RuntimeError` that includes the missing-models list.

Canonical validation: 2685 passed (unchanged from the merge-resolve
baseline), pyright 0/0/0, ruff clean, coverage 97.71%.

* #157: Address codecov patch-coverage gaps (4 lines in _rollup.py)

Codecov flagged 97.57% patch coverage on PR #162 with 4 missed lines:

Lines 124-125 (post-PR-review-fix import-time guard): the new
`if/raise RuntimeError(...)` block that replaced the stripped-under-O
assert can't be triggered at module-load without an importlib.reload
dance. Refactored: extracted the predicate to a module-level
`_verify_provider_prefix_coverage(prices, model_to_provider)` helper
that the module body calls inline. Helper is unit-testable directly
with two cases (matching + mismatched).

Lines 298-299 (ValidationError branch in _ingest_jsonl): the existing
`test_rollup_malformed_jsonl_line_raises_typed_error` exercises only
the JSONDecodeError branch. Added
`test_rollup_valid_json_but_invalid_event_shape_raises_typed_error`
that writes a JSONL line that parses as JSON but fails Pydantic's
LLMResponseEvent.model_validate, exercising the
`except ValidationError` arm. Also strengthened the existing test to
assert `JSONDecodeError` appears in `reason`, so the two branches
are pinned by name.

_rollup.py now at 100% coverage (135/135 lines). Total project
coverage 97.71% → 97.77%. 3 new test cases (2688 total).

* #163: drafter business-rules fidelity (plan)

Add super-plan for #163 covering:
- DEC-001: Lever B + C1 (dynamic-block envelopes + parser cardinality gate)
- DEC-002: at-least-one-per-rule cardinality
- DEC-004: thread business_rules through parse_draft_response (mirror #159)
- DEC-005: reuse PromptEnvelopeBreachError with parameterised envelope
- DEC-008: exclude_tests=('custom_sql',) short-circuits both surfaces
- DEC-009: <BUSINESS_RULE id="N">...</BUSINESS_RULE> envelope format

Four stories: dynamic-block hardening, parser gate, Quality Gate,
Patterns & Memory. ~100 LOC code + ~30 LOC prose. No _PROMPT_VERSION
rotation; pinned by US-001 AC #7 as the load-bearing cache-stability gate.

* #163: devolve plan to beads (epic bd_1-scaffolding-74b)

Phase 7 — populate Beads manifest with epic + 4 task IDs and update
phase marker to 'devolved'.

Epic: bd_1-scaffolding-74b
  .1 US-001 — Dynamic-block envelope hardening + parameterised breach guard
  .2 US-002 — Parser cardinality gate + business_rules threading (blocked on .1)
  .3 US-003 — Quality Gate (blocked on .1, .2)
  .4 US-004 — Patterns & Memory (blocked on .3)

Ready next: bd_1-scaffolding-74b.1. Run /ralph-run from this worktree
to execute the chain.

* bd_1-scaffolding-74b.1: dynamic-block envelope hardening + parameterised breach guard (US-001 of #163)

Replace the bulleted `## BUSINESS RULES` list in `_render_business_rules_section`
with numbered `<BUSINESS_RULE id="N">…</BUSINESS_RULE>` envelopes (DEC-009).
Each rule body indented exactly 2 spaces, preserving the existing
`(model) `/`(column X) ` scope prefix verbatim.

Extend `PromptEnvelopeBreachError` to be envelope-parameterised (DEC-005):
new keyword-only `envelope: str = "MODEL_SQL"` and `rule_index: int | None`
kwargs. The default rendering is byte-equal to the pre-#163 message so
the existing call site in `prompts.py` keeps working unchanged. When
`envelope="BUSINESS_RULE"` with `rule_index` set, the message names the
1-indexed offending rule.

Add a pre-render breach guard: `_render_business_rules_section` scans
each rule for the literal `</BUSINESS_RULE>` substring (boring substring
match per the `</MODEL_SQL>` precedent — no whitespace/case normalisation)
and raises `PromptEnvelopeBreachError` with the 1-indexed rule index.

Short-circuit the section to `""` when `"custom_sql"` is in
`DraftConfig.exclude_tests` (DEC-008) — don't tell the LLM to draft rules
it can't emit. Thread `exclude_tests` through `_render_dynamic_block` and
`render_prompt` so the caller's already-known exclusion set reaches the
business-rules renderer without re-reading config.

`_PROMPT_VERSION` is unchanged (`c9e7ee1f6f465933`) — all changes scope to
the dynamic block and the errors module; the cached system prompt
templates are untouched. `tests/llm/test_prompt_cache_stability.py` stays
green.

Traces to: DEC-001, DEC-005, DEC-008, DEC-009 of
plans/super/163-drafter-business-rules-fidelity.md.

* bd_1-scaffolding-74b.2: parser cardinality gate + business_rules threading (US-002 of #163)

Adds keyword-only `business_rules: tuple[str, ...] = ()` to
`parse_draft_response` and `_validate_anchor_contract`. Threads it from
`draft_from_request` (in `signalforge.draft.schema`) using the existing
`_read_business_rules(model)` helper from `prompts.py` as the single
source of truth — mirrors the `model_columns_by_type` threading style
from issue #159.

Gate (DEC-002, DEC-008): when `business_rules` is non-empty AND
`"custom_sql"` is NOT in `exclude_tests`, count `custom_sql` tests
across both `candidate.tests` (model-level) and every `column.tests`
(column-level), and append one collect-all violation when the count
falls below `len(business_rules)`. At-least-one-per-rule semantics:
excess is allowed (legitimate multi-test decomposition of a complex
rule).

Violation message (DEC-006) names every declared rule verbatim via
`repr()` so the operator sees exactly which rules they declared:
"Expected ≥N custom_sql test(s) (one per declared business rule),
got M. Declared rules: '(model) rule one', '(column X) rule two'."

11 new TDD tests in `tests/draft/test_parser.py` cover under-coverage
rejection, coverage match, over-coverage allowed, both no-op paths
(empty rules with/without custom_sql), exclude_tests short-circuit,
model-level / column-level / mixed counting, the pinned violation
message shape, and collect-all parity with other violations.

The gate is a no-op when `business_rules=()` so all 36 existing
parser-test call sites continue to work unchanged. No new error class,
no new exit-code-table entry, no prompt rendering touched, no
`_PROMPT_VERSION` rotation — cache-stability test still passes.

* bd_1-scaffolding-74b.3: Quality gate — fix bugs from code review + CodeRabbit

US-003 (#163) inline Quality Gate. 4 code-review passes ran in parallel
on the US-001+US-002 diff; this commit lands the real signal from those
passes as 5 invariant tests (no production-code changes — the diff
itself was found contract-compliant and correctness-clean).

Findings landed:

1. Pass 3 (coverage) finding 1 — pin the constructor invariant for the
   state-mismatched 'envelope="BUSINESS_RULE", rule_index=None' call so a
   future refactor (e.g. silent default to rule_index=1) can't regress
   the BUSINESS_RULE-side rendering. Production call sites always pair
   the two; this is the latent-invariant gate.

2. Pass 3 (coverage) side observation — pin the rotated default_remediation
   text. AC #5's byte-equality applies to .message (already pinned); the
   accompanying remediation hint was deliberately rotated to cover BOTH
   envelopes ('</MODEL_SQL>' and '</BUSINESS_RULE>') so operators of the
   new envelope see an actionable steer. Pinning the new text prevents a
   silent re-rotation back to MODEL_SQL-only wording.

3. Pass 3 (coverage) finding 2a — boring substring match invariant: a
   rule containing the bare opening tag '<BUSINESS_RULE>' (no slash)
   does NOT terminate the envelope and must render. Mirrors the safety /
   grade envelope contract.

4. Pass 3 (coverage) finding 2b — truncated closing fragment
   '</BUSINESS_RUL' is NOT a breach. Pins the exact-substring contract
   so a future 'be helpful' regex / case-normalisation refactor can't
   silently widen the match.

5. Pass 3 (coverage) finding 3 — branch-order invariant: the
   exclude_tests short-circuit beats the breach scan. An adversarial
   rule containing '</BUSINESS_RULE>' does NOT raise when 'custom_sql'
   is excluded because the section never renders. Pins the order.

Pass 4 (cross-cutting) finding — 'import pytest as _pytest' alias
dropped in favour of plain 'import pytest' to match the in-file
precedent at test_render_dynamic_block_rejects_closing_tag_in_raw_code
(line 515).

Pass 1 (correctness): no P0/P1 bugs.
Pass 2 (contract): no DEC / rule-file deviations.

Validation: 2662 passed (+5 new), 97.72% coverage, _PROMPT_VERSION
unchanged at c9e7ee1f6f465933 (cache-stability gate green).

* bd_1-scaffolding-74b.4: Patterns & Memory — rule files + ops docs + plan-doc closeout

US-004 (#163) inline Patterns & Memory.

Updates the durable conventions established by #163:

- docs/draft-ops.md — three new subsections:
  1. 'Numbered envelope shape (<BUSINESS_RULE id="N">...</BUSINESS_RULE>)'
     documenting the envelope format + breach guard contract
     (boring substring match, opening tag / truncated fragments allowed)
  2. 'Cardinality contract (at-least-one-per-rule)' documenting the
     parser-side gate, the verbatim violation message shape, and the
     collect-all preservation
  3. ''exclude_tests' short-circuit' documenting the no-op on both
     surfaces when 'custom_sql' is in DraftConfig.exclude_tests

- .claude/rules/business-rule-tests.md — 'Two input paths' section
  extended with the #163 'gate-over-prompt' subsection covering:
  * Dynamic-block envelope (DEC-009 of #163)
  * Parser cardinality gate (DEC-002 / DEC-006 of #163)
  * exclude_tests short-circuit (DEC-008 of #163)
  * Load-bearing 'no _PROMPT_VERSION rotation' note pointing at
    tests/llm/test_prompt_cache_stability.py as the regression gate

- .claude/rules/llm-drafter.md — '<MODEL_SQL> prompt-injection envelope'
  section heading updated to call out the #163 parameterisation; a new
  paragraph documents the envelope-parameterised PromptEnvelopeBreachError
  pattern (one class, N raise sites; never a new error subclass).
  Future envelopes follow this shape.

- plans/super/163-drafter-business-rules-fidelity.md — Beads manifest
  updated with final statuses (all 4 stories closed) + commit hashes;
  phase marker advanced to 'complete'.

Validation: 2662 passed, 97.72% coverage. _PROMPT_VERSION unchanged
at c9e7ee1f6f465933.

Note: workers cannot write to .claude/ in worktrees (orchestrator-only
per the ralph-worker-claude-dir-perms convention), so US-004's bead
description flagged that the .claude/rules/*.md edits would be applied
inline by the orchestrator. That's what happened here.

* #163: Address PR review feedback — markdownlint MD038 + MD040

CodeRabbit found 3 markdownlint warnings on the docs/rules added by
US-004:

1. .claude/rules/business-rule-tests.md:19 — MD038 (spaces inside
   inline code spans). Dropped trailing spaces inside backticks:
   '(model) ' -> '(model)', '(column X) ' -> '(column X)'.
2. docs/draft-ops.md:304 — same MD038 fix.
3. plans/super/163-drafter-business-rules-fidelity.md:30 — MD040
   (fenced code block missing language tag). Added 'text' language
   to the 'BUSINESS RULES' rendered-output illustration. Also fixed
   the line-122 MD038 same as (1)/(2).

All three are valid markdownlint findings; fixed inline per the
closeout rule 'NEVER SILENTLY DEFER ANYTHING.'

Validation: 2662 passed, 97.72% coverage. _PROMPT_VERSION unchanged.

* docs(#134): LLM-provider deep-dive + README cross-links

#134 (the pluggable-provider epic) shipped via #135 / #136 / #137 but
the user-facing docs covered provider selection only inside the
per-stage drafter and grader ops pages. Add a top-level
`docs/llm-providers-ops.md` that pulls the story together — where
LLMs are (and aren't) used, the provider-neutral seam shape, a
capability matrix across Anthropic / OpenAI / Gemini, per-provider
sections, choosing-a-provider guidance, cost + caching tradeoffs,
the reliability + audit story, and an "adding a fourth provider"
recipe.

README changes:

- New "Supported LLM providers" section mirroring the existing
  "Supported warehouses" section structure (table + one-paragraph
  intro) so first-time readers see the three providers and the
  install / env-var shape immediately.
- Trim the long OpenAI / Gemini bullet list in Quick start §2 to a
  single paragraph pointing at the deep dive (the table above
  already carries the install + env-var info).
- Fix a stale `call_anthropic` reference in the "How drafting works"
  ASCII diagram to `call_llm` (renamed in #135) and add a one-line
  pointer to the new deep dive.

mkdocs nav gains an "LLM Providers" entry between Pipeline Stages
and Cost Estimate.

`mkdocs build` succeeds with no new warnings beyond the existing
false-positive heading-anchor pattern that `cost-estimate-ops.md`
already triggers (mkdocs and pymdownx disagree on a few anchor
slugs; the headings exist and resolve correctly on GitHub Pages).

* docs(#134): add prompt-caching explainer + per-provider rationale

Reviewer feedback on the deep dive: the capability matrix marks
Anthropic ✅ and OpenAI / Gemini ❌ for prompt caching, but doesn't
say what caching IS in business terms or WHY the asymmetry exists.
Closing that gap is the single most consequential row for anyone
budgeting a real workload.

Adds a "Prompt caching — what it is and why providers differ"
section between Supported providers and Choosing a provider:

- Business framing: caching is the provider's "pay a write premium
  once, get steep cache-read discount on subsequent calls" offer.
  Anthropic Sonnet 4.6 rate table (write +25% premium / read 90%
  discount) makes the break-even concrete (one follow-up call).
- Where it matters in SignalForge: modest on the 1-call drafter,
  load-bearing on the ~48-call grader fan-out where the cached
  rubric block hits cache 47 of 48 times.
- Why OpenAI isn't supported: their Chat Completions prompt-caching
  is automatic + opaque (no `cache_control` marker, no public
  per-MTok rates, no `cache_creation_input_tokens` field in usage).
  We can't steer, price, or audit it — so the honest posture is
  `supports_prompt_caching=False` + silently-ignored `cache_ttl`.
- Why Gemini isn't supported yet: their context caching is real but
  ships as a separate API surface (`CachedContent.create` + handle
  reference) with a distinct pricing dimension (storage per hour +
  discounted reads). Different code path than Anthropic's inline
  marker; tracked as a follow-up to #137.
- Practical bottom line: per-token cheaper providers (Gemini Flash,
  gpt-4o-mini) typically still beat Anthropic-with-caching on
  absolute dollars — they're just leaving optimization on the
  table.

* #135: provider-neutral LLM seam (plan) (#148)

* Add super plan for #135: provider-neutral LLM seam



* Mark #135 plan published (PR #148)



* Mark #135 plan devolved (beads epic bd_1-scaffolding-j2c)



* bd_1-scaffolding-j2c.1: US-001 provider foundation (ExceptionCategory, UsageMetrics, LLMProvider ABC, registry)

Adds the provider-neutral LLM seam foundation (DEC-001/002/003 of #135):

- src/signalforge/llm/providers.py: ExceptionCategory (5-member enum),
  UsageMetrics (frozen pydantic value object, cache fields default 0),
  LLMProvider ABC, and the process-level registry (register_provider /
  provider_for). No vendor behaviour wired; registry starts empty.
- UnknownProviderError(LLMError) in errors.py — lists available registered
  provider names, repr-safe message, default_remediation; registered at
  CLI exit-code tier 2 (looked-up-identifier-not-in-table input failure).
- Exported the new public names from signalforge.llm.__all__; updated the
  documented-surface lists in test_public_api.py / test_schema.py and the
  errors count in test_errors.py.



* bd_1-scaffolding-j2c.2: US-002 AnthropicProvider strategy + _anthropic_client rename + AST scan



* bd_1-scaffolding-j2c.3: US-003 generic call_llm orchestrator (rename, capability gating, strategy dispatch)

Collapse call_anthropic into a provider-neutral call_llm orchestrator:
- Resolve strategy via provider_for(provider); build client via
  strategy.make_client() when client is None (DEC-006).
- Pre-send count gate now gated on strategy.supports_token_count; cache
  marker / beta header + dual-zero anomaly WARNING gated on
  supports_prompt_caching (DEC-008). Anthropic = both True ⇒ byte-identical.
- Retry loop dispatches on strategy.classify_exception -> ExceptionCategory
  (DEC-001) instead of catching Anthropic SDK classes directly; per-class
  budgets, backoff math, WARNING shape, exhaustion raises preserved.
- Response assembled via strategy.extract_text_blocks/extract_usage.
- Neutral _LLMClientProtocol narrows the resolved client so no vendor-SDK
  type / type-checker suppression leaks into llm.client (DEC-012 confinement).

Drop call_anthropic (name + __all__); add call_llm. Migrate draft_from_request
and grade._grade_one call sites + all client/retry/public-api/schema tests.



* bd_1-scaffolding-j2c.4: US-004 provider config field + stage threading + CLI client-construction migration

DEC-006/007 of #135. Adds a registry-validated `provider: str = "anthropic"`
field to DraftConfig and GradeConfig, each with a field_validator that
delegates to providers.provider_for (raises UnknownProviderError listing
available names on an unknown value — fails loud at config load). Threads
provider=config.provider into call_llm from draft_from_request and
grade._grade_one.

Migrates the CLI generate path off the in-CLI _make_anthropic_client helper
(removed): the real-run draft/grade stages now pass client=None so call_llm
lazy-builds the client via the configured provider. The --estimate
short-circuit (Anthropic-specific count_tokens) builds its concrete client via
provider_for(draft_config.provider).make_client(). Migrates the 7 CLI
monkeypatch tests: 5 batch/select tests drop the orphaned make_anthropic_client
mock; the estimate test patches AnthropicProvider.make_client; test_lint
unchanged (it patches the LLM shim, which still exists).



* bd_1-scaffolding-j2c.5: US-005 no-cache fake provider neutrality proof (AC #2/#3)



* bd_1-scaffolding-j2c.6: US-006 docs + surface parity (docs/ portion)

Update operator-facing docs for the provider-neutral LLM seam (#135):
- call_anthropic -> call_llm; llm._client -> llm._anthropic_client
- document the provider config knob (llm.provider / grade.provider),
  default "anthropic", registry-validated, forward-looking plugin seam
- note prompt caching + count_tokens are now provider capabilities
  (supports_prompt_caching / supports_token_count); Anthropic unchanged



* bd_1-scaffolding-j2c.6: US-006 .claude/rules seam-rename + provider-seam accuracy

Orchestrator-only rule-file edits (workers can't write .claude/ in worktrees).



* bd_1-scaffolding-j2c.7: Quality gate — fix bugs from code review

- providers.build_count_tokens_kwargs: correct docstring (probe omits the
  cache_control marker because it doesn't affect the token count; the old
  claim of "matching the inline call_anthropic probe" was inaccurate).
- call_llm: gate cache_marker_active on BOTH supports_prompt_caching AND
  supports_token_count, so a future caching=True/token_count=False provider
  degrades to no-caching rather than sending an unvalidated cache_control
  marker (no sub-minimum drop / no oversize cap). Anthropic is True/True so
  the default path is a no-op. (4-pass review latent-trap finding.)

CodeRabbit: skill not available in this environment — skipped.



* bd_1-scaffolding-j2c.8: Patterns & Memory — provider-seam convention + QG lesson

- llm-drafter.md: capability-gating lesson (gate the cache marker on BOTH
  supports_prompt_caching AND supports_token_count — the #135 QG latent-trap
  finding) for future #136/#137 provider authors.
- Added `provider` to the documented `llm:` config block.
- Reference section now cites plans/super/135 + the no-cache neutrality proof.



* #135: close Codecov patch gaps — count_tokens probe error mapping + classify fallthrough

The provider-neutral refactor rewrote the count_tokens pre-send probe's
error-mapping as new lines (auth/rate-limit/conn/5xx/other -> typed LLMError,
no retry on the probe) that the existing retry tests (messages.create path)
never exercised. Add 6 probe-failure tests + a missing-input_tokens case
(client.py 320-348 now covered, 87% -> 96%).

Also cover AnthropicProvider.classify_exception's defensive fallthrough for a
non-5xx/non-4xx-non-auth APIStatusError (3xx) -> NO_RETRY (providers.py -> 100%).

Remaining uncovered client.py helper branches (_extract_text_blocks /
_extract_usage_field malformed-response raises) are pre-existing and not part
of the #135 diff.



* #135: address PR review (CodeRabbit/Copilot)

- Stale-symbol docstrings: rename every `call_anthropic` :func: reference to
  `call_llm` across llm/{__init__,models,_anthropic_client,providers}.py,
  draft/schema.py, grade/{engine,config,errors}.py, cli/_estimate.py; reword
  the AnthropicProvider "preparatory refactor" note (US-003 already collapsed
  the duplication); rewrite the llm package docstring to the provider-neutral
  seam.
- client.py: count_tokens NO_RETRY fallback message no longer claims a "status"
  (it also covers non-status exceptions) — now "failed with a non-retryable error".
- generate.py --estimate: fail fast with CliInputError when draft.provider !=
  grade.provider or the provider isn't 'anthropic' (the estimate engine drives a
  single Anthropic-cast count_tokens client across both configs). + 2 regression
  tests.
- plan SD-1: drop the stale `Literal` wording (DEC-007 settled it as a
  registry-validated str).

* docs(readme): refresh status, generalize config, redraft roadmap (#153)

* docs(readme): refresh status, generalize config, redraft roadmap

The v0.1 "Status:" line was four releases stale and BigQuery-only.
Replace with a Supported-warehouses block covering BigQuery (v0.1) and
Snowflake (v0.3 — incl. the deferred aggregate-only / column_stats
limitation), generalize Configuration to dispatch on dbt profile type,
and redraft the Roadmap into Shipped (v0.1/v0.2/v0.3 with release dates)
+ Planned (Gemini/OpenAI → installable skill → Airflow → GitHub Action
→ rubric customization → dbt Fusion). Drop the now-stale "prune-existing
is dev-branch only" and "first four ship; prune-existing is v0.2 dev"
callouts.



* docs(readme): add custom-business-logic callout, strip non-roadmap version markers

- Add a **Custom business logic** paragraph alongside Supported warehouses,
  explaining `meta.signalforge.business_rules` → `custom_sql` drafting + the
  ownership-marker write semantics + always-pass drop behaviour.
- Remove every version marker outside the Roadmap section: "since v0.1/v0.3"
  in the warehouses block, "*(v0.2)*" on the prune-existing bullet, the "v0.2
  default" config comment, the "(v0.1)"/"(v0.3)" subsection headers, and the
  "pre-alpha … v0.1 milestone" line in Contributing.



* docs(readme): reorganize scope callouts; promote Supported warehouses to its own H2

The two bolded standalone paragraphs at the top of the README (Supported
warehouses, Custom business logic) sat before the "Why this exists" pitch
and front-loaded dense capability detail. The custom-business-logic block
was also triple-covered (standalone block + "What it does" bullet +
Quick-start worked example).

- Drop both standalone bolded paragraphs from the top.
- Promote Supported warehouses to a proper H2 between "How it works"
  and the "Live on PyPI" callout — brief, points to Configuration for
  per-warehouse setup; Snowflake's known limitation stays in its single
  home under Configuration > Snowflake.
- Strengthen the custom-business-rule bullet in "What it does" with the
  "fifth test type" framing and a direct link to the worked example, so
  the feature stays prominent without a redundant top-of-readme banner.

New flow: pitch → features → architecture → scope → quickstart → reference.

* #136: OpenAI grading provider (plan) (#152)

* #136: super plan for OpenAI grading provider

Phase: detailing (awaiting approval).

13 DECs captured: Chat Completions API, no provider/model cross-validation,
fully wire --estimate for OpenAI (new estimate_input_tokens ABC), default
judge gpt-4o, scope both grade + draft, server-side response_format=json_object,
four pricing SKUs (gpt-4o, -mini, 4.1, 4-turbo), live smoke covers grade +
estimate, .messages adapter wraps chat.completions, AST Scan 3 extension,
[openai] extra + lazy tiktoken, Anthropic estimate byte-identity floor.

9 stories: shim + AST confinement, OpenAIProvider + registration, FakeOpenAIClient
+ neutrality test, pricing entries, --estimate provider-aware counting,
live gated smokes, docs, Quality Gate, Patterns & Memory.



* #136: link plan to PR #152 (phase=published)



* #136: apply 5 plan revisions from #137 cross-review

Cross-review against #137 (Gemini grading) plan surfaced 5 substantive gaps
in the OpenAI plan:

1. DEC-010 — fix wording: a NEW 9th AST scan (Scan 3 is Anthropic-specific),
   not an extension. Reuse _QualifiedNameCallFinder + three-pattern bypass
   regression test per testing-signal.md.
2. DEC-012 — fix pyproject.toml listing: three slots in lockstep
   ([project.optional-dependencies].openai + .dev + [dependency-groups].dev),
   mirroring Snowflake precedent per python-build.md. Plan previously named
   only two.
3. DEC-014 (new) — codify the _load_openai_exception_classes empty-tuple
   fallback on ImportError (mirrors AnthropicProvider). Includes refusal /
   content-filter symmetry note explaining why OpenAI needs no Gemini-style
   safety_filter typed-degrade DEC.
4. US-006 — add a third live test (draft_schema) honouring DEC-005's
   "scope both stages" commitment at live level too. DEC-008 updated to
   match (three tests, not two).
5. New "Open notes for implementation" section — pragmatic SDK-class-name
   verification, .messages adapter shape confirmation, tiktoken fallback
   table, response_format prompt-requirement check, Anthropic byte-identity
   snapshot capture protocol.

Plus a new "Worker-writability routing" section codifying that US-009
(Patterns & Memory) is orchestrator-only because it edits .claude/rules/,
mirroring #137's same routing.

Plan grows from 319 → 343 lines (+40/-17).



* #136: devolve plan into bd beads (epic bd_1-scaffolding-4tw + 9 tasks)

Fills in the Beads manifest section. Epic bd_1-scaffolding-4tw with 9
child tasks (US-001 … US-009) created with dep edges per the plan's
"Depends on:" lines:

  US-001 → none                          (READY)
  US-002 → US-001
  US-003 → US-002
  US-004 → none (parallel-safe)          (READY)
  US-005 → US-002, US-004
  US-006 → US-002, US-005
  US-007 → US-001, US-002, US-005
  US-008 → US-001..US-007                (QG)
  US-009 → US-008                        (P&M; orchestrator-only)

Cross-epic gate wired downstream: #137's sentinel bd_1-scaffolding-41a
now DEPENDS ON US-009, so #137 US-007 stays mechanically blocked until
this epic completes + sentinel closes after PR #152 merges to dev.

Parallel-safe at the entry points: US-001 and US-004 edit disjoint
files (shim/pyproject/AST vs pricing) — ralph-serialize-shared-registry
does not apply. Run concurrently.

bd ready (post-devolve) surfaces .1 + .4 of this epic + the two epics
themselves + the unrelated Airflow integration.



* bd_1-scaffolding-4tw.4: #136 US-004 — OpenAI pricing SKUs (gpt-4o + 3 siblings)

Adds four OpenAI SKUs to _PRICES_MUTABLE per DEC-007: gpt-4o (default
judge per DEC-004), gpt-4o-mini (budget), gpt-4.1 (newer flagship),
gpt-4-turbo (back-compat). Cache fields = 0.0 (OpenAI has no equivalent
cache discount). PRICE_TABLE_VERSION bumped to 2026-05-28.

Anthropic SKUs unchanged (byte-identical) — Anthropic estimate
byte-identity floor (DEC-013) preserved at the pricing layer.

Tests assert: non-zero input/output rates + zero cache fields for all
four; unknown model still raises EstimateUnknownModelError; Anthropic
SKUs unchanged; version bump pinned.

OpenAI per-MTok rates are calibration figures captured at PR-prep time
pending operator verification against https://openai.com/api/pricing/;
the figures are sanity-check baselines, not billing guarantees.

Traces: DEC-003, DEC-004, DEC-007.



* bd_1-scaffolding-4tw.1: #136 US-001 — _openai_client.py shim + [openai] extra + 9th AST scan

Implements the per-vendor shim confining every openai SDK type ignore.
Adds [openai] optional-dep extra (openai + tiktoken) in three-slot
lockstep across [project.optional-dependencies].openai, .dev, and
[dependency-groups].dev. Adds the new 9th AST scan in
tests/test_audit_completeness.py reusing _QualifiedNameCallFinder
(NOT an extension of Scan 3 — Scan 3 is Anthropic-specific) and a
companion per-file confinement test mirroring Snowflake's. Bumps the
docstring tally 8→9.

DEC-014 empty-tuple ImportError fallback on _load_openai_exception_classes
mirrors AnthropicProvider; tiktoken cl100k_base fallback for unknown
model ids.

Traces: DEC-001, DEC-009, DEC-010, DEC-012, DEC-014.



* bd_1-scaffolding-4tw.2: #136 US-002 — OpenAIProvider + registration + config-validator coverage

Implements OpenAIProvider(LLMProvider) with both capability flags False
(no prompt caching, no pre-send token count) — mirrors FakeNoCacheProvider
end-to-end shape. build_create_kwargs attaches response_format=
{type: json_object} per DEC-006 (server-side JSON enforcement); no
cache_control / extra_headers. extract_text_blocks reads
response.choices[0].message.content; extract_usage maps usage.prompt_tokens
+ completion_tokens → UsageMetrics with cache fields 0. classify_exception
covers all five ExceptionCategory branches via _load_openai_exception_classes
from the US-001 shim.

register_provider(OpenAIProvider()) at module scope so GradeConfig/
DraftConfig validators accept provider='openai'. Exported from
signalforge.llm.__init__.

Tests pin: each ABC method's contract; config validator acceptance for
both stages; UnknownProviderError lists both anthropic and openai.

Traces: DEC-001, DEC-005, DEC-006, DEC-009, DEC-011.



* bd_1-scaffolding-4tw.3: #136 US-003 — FakeOpenAIClient + grade neutrality e2e

Adds tests/llm/_fake_openai.py with FakeOpenAIClient + expect_messages_create
API mirroring FakeAnthropicClient verbatim. Support dataclasses match the
real chat-completions response shape (choices[0].message.content; usage
with prompt_tokens + completion_tokens).

Adds tests/grade/test_provider_neutrality_openai.py — the OpenAI analogue
of the FakeNoCacheProvider neutrality proof. Asserts cache_*=0 in JSONL
audit, blake2b-8 reproducibility hashes present, sidecar drift-detector
round-trip, no dual-zero cache-anomaly WARNING in caplog, all expectations
consumed.

Traces: DEC-001, DEC-005, DEC-006, DEC-009, DEC-011.



* bd_1-scaffolding-4tw.5: #136 US-005 — --estimate provider-aware token counting

Adds LLMProvider.estimate_input_tokens(model, text, *, client=None) -> int
as an abstract method on the ABC (DEC-003). AnthropicProvider impl
delegates to the SDK's messages.count_tokens with a single user-message
text envelope; OpenAIProvider impl delegates to _count_openai_tokens
(tiktoken with cl100k_base fallback per DEC-012); FakeNoCacheProvider
and _DummyProvider impls return trivial deterministic answers so the
existing neutrality + registry tests still pass.

Refactors cli/_estimate.py: _count_draft_tokens and the grader-side
equivalent dispatch through provider_for(config.provider).estimate_input_tokens
— no more hard-coded anthropic_client.messages.count_tokens calls. The
engine signature relaxes anthropic_client to 'object | None' so the
OpenAI path can pass None (tiktoken is local). Lifts the
'--estimate currently supports only provider=anthropic' gate in
cli/generate.py; the divergent-providers check stays (the engine still
takes one optional client).

Pins DEC-013 Anthropic byte-identity floor via
tests/cli/test_estimate.py::test_estimate_anthropic_byte_identity_golden
and tests/fixtures/estimate/anthropic_byte_identity_golden.txt (captured
2026-05-28 before the refactor; reproduced verbatim after). New
companion tests prove the OpenAI path produces non-zero token counts
+ non-zero USD, ignores the threaded anthropic_client, and goes through
_count_openai_tokens (patched-helper assertion).

Traces: DEC-003, DEC-007, DEC-012, DEC-013.



* bd_1-scaffolding-4tw.7: #136 US-007 — operator docs + CHANGELOG (worker-writable portion)

Updates operator-facing documentation surfaces for OpenAI grading +
drafting:
- docs/grade-ops.md — OpenAI provider section (config snippet,
  OPENAI_API_KEY, no-cache caveat, live smoke gating link)
- docs/draft-ops.md — equivalent for llm.provider: openai
- docs/cost-estimate-ops.md — tiktoken note, [openai] extra install,
  four pricing SKUs
- CHANGELOG.md — [Unreleased] Added entry for #136
- README.md — provider enumeration extended (if applicable)

The .claude/rules/llm-drafter.md update is deferred to US-009
(Patterns & Memory) per the project's worker-writability rule
(orchestrator-only edits under .claude/).

Traces: DEC-001 through DEC-014.



* bd_1-scaffolding-4tw.6: #136 US-006 — live gated smoke tests (openai marker + 3 tests)

Adds @pytest.mark.openai marker + three gated live-API tests:
- tests/grade/test_smoke_real_api_openai.py — grade_artifacts(provider=openai)
- tests/draft/test_smoke_real_api_openai.py — draft_schema(provider=openai)
  (honors DEC-005 both-stages at live level)
- tests/cli/test_e2e_estimate_openai.py — generate --estimate openai

All three env-gated on SF_RUN_OPENAI=1 + OPENAI_API_KEY via belt-and-
suspenders _skip_reason() helper per testing-signal.md. Marker registered
in pyproject.toml + added to addopts exclusion so default pytest doesn't
collect them. CONTRIBUTING.md documents the maintainer-only run pattern.

Traces: DEC-001, DEC-004, DEC-005, DEC-008.



* bd_1-scaffolding-4tw.8: #136 Quality Gate — fix 2 majors + 1 minor from code review x4

Code-review pass 3 surfaced two correctness MAJORS + pass 4 surfaced
a doc MINOR; all fixed inline per /ralph-run Step 3b. Pass 1, 2, 4
(other surfaces) reported no correctness bugs.

MAJOR 1 — EstimateUnknownModelError.default_remediation enumerated
only the three Anthropic SKUs. An operator typo on an OpenAI SKU
got pointed at Anthropic options (violates "errors carry remediation"
in manifest-readers.md). Updated to enumerate all 7 SKUs
(claude-sonnet-4-6, claude-opus-4-7, claude-haiku-4-5, gpt-4o,
gpt-4o-mini, gpt-4.1, gpt-4-turbo) + refreshed the locked-text test
that pinned the stale string.

MAJOR 2 — AnthropicProvider.estimate_input_tokens dropped the
pre-refactor `system=` kwarg, concatenating system+cached+dynamic
into a single user-content string. Anthropic's server-side tokenizer
counts the system block with its own envelope tokens; without the
kwarg, real-API counts under-report by the system-envelope size.
The fake-driven byte-identity test passed only because the fake
returned canned input_tokens regardless of kwargs (so rendered-output
identity held, but DEC-013's "byte-identity vs the pre-refactor
Anthropic count_tokens call" spirit broke at the real-API level).

Fix extends the ABC signature with a keyword-only `system: str = ""`
parameter. AnthropicProvider passes it via `system=` kwarg when
non-empty (matches pre-refactor real-API call shape). OpenAIProvider
concatenates `system + text` before tiktoken (tiktoken has no
system-envelope distinction; the total still counts every token).
FakeNoCacheProvider concatenates for the word-count proxy.
_DummyProvider gains the new kwarg for ABC parity. cli/_estimate.py
callers (_count_draft_tokens, _count_grade_criterion_tokens) thread
`system=` separately; grade-side preserves the pre-existing
double-count of the rubric (passed as both system= AND in user content)
to keep byte-identity with the pre-refactor shape.

MINOR — docs/grade-ops.md:118 config-snippet comment said "only
anthropic registered today", contradicting the same file's later
"## OpenAI provider" section and docs/draft-ops.md's correct
wording. Updated to mirror draft-ops's form.

Validation: ruff/pyright/pytest all green (2498 passed, 62 deselected,
97.34% coverage); wheel_smoke green (2 passed).

Note: CodeRabbit skill not available in this environment, skipped
per Step 3b "(if available)".



* bd_1-scaffolding-4tw.9: #136 Patterns & Memory — codify OpenAI seam conventions

Orchestrator-only commit (workers can't write under .claude/ in
worktrees per ralph-worker-claude-dir-perms.md).

Updates .claude/rules/llm-drafter.md to capture three durable patterns
from #136:

1. Provider-neutral seam — adds OpenAI as the second registered
   provider (name="openai", both capability flags False) and extends
   the LLMProvider ABC surface enumeration with the new
   estimate_input_tokens(model, text, *, system="", client=None)
   method (#136 US-005).

2. "OpenAI provider shape" subsection — codifies the .messages.create
   façade adapter pattern (SimpleNamespace delegating to
   chat.completions.create), the response_format={type:json_object}
   server-side JSON enforcement (with the cross-ref to issue #144's
   tolerant parser as fallback), and the tiktoken cl100k_base
   fallback for unknown model ids. This becomes the canonical
   precedent for #137 Gemini's response_mime_type=application/json
   equivalent.

3. estimate_input_tokens(*, system=...) — documents the load-bearing
   reason the system envelope is threaded separately (Anthropic's
   server-side tokenizer applies system-block envelope tokens; dropping
   the kwarg under-reports real-API counts silently because
   fake-driven byte-identity tests can't catch call-shape drift). Also
   pins the deliberate double-count of system_and_rubric in
   _count_grade_criterion_tokens as pre-existing behaviour that must
   be preserved.

Bumps AST-scan tally section from "four" → "five" (adds the openai.OpenAI
9th-project-scan); flags #137 Gemini as the 10th. Updates the
References block with #136 plan + new files.

Memory entry: ~/.claude/projects/.../memory/fake-driven-byte-identity-
blind-spot.md captures the QG lesson (fakes return canned values
regardless of kwargs → call-shape drift slips past rendered-output
snapshots → needs explicit kwargs-shape assertion OR live test).
Indexed in MEMORY.md.

Validation: all four canonical gates green (2498 passed, 97.34%
coverage).



* #136: address PR #152 review (6 actionable + meta)

Copilot:
- MAJOR _estimate.py:359 — OpenAI grade-side over-counted rubric. The
  first QG fix preserved a pre-existing Anthropic double-count of
  system_and_rubric (passed as both system= AND in user content),
  which triple-counted on OpenAI (system→system+text concat → rubric
  prefix in text). Corrected to match the runtime grader call: rubric
  in system= once, artifact envelope in user content. Anthropic real-
  API counts drop one rubric copy from the buggy pre-refactor bytes;
  OpenAI counts each input once. Fake-driven byte-identity golden
  still passes (canned token counts are call-shape-agnostic).
  CHANGELOG documents the calibration shift.
- NIT _estimate.py:421 — renamed anthropic_client → client. Type was
  already object | None and forwarded to whichever provider strategy
  is active; old name implied Anthropic-only and would mislead a
  future #137 Gemini wiring. CLI in generate.py already passed None
  for non-Anthropic; rename surfaces the contract without behaviour
  change.
- META plan/PR description — addressed by updating the PR body
  separately (not part of this commit).

CodeRabbit:
- CONTRIBUTING.md:64 — added snowflake to the gated-marker audit
  command + the corresponding SNOWFLAKE_* env vars.
- tests/llm/_fake_provider.py:234 — boundary-word undercount fix in
  the FakeNoCacheProvider word-count proxy (f"{system} {text}" with
  a delimiter; was system+text which merged the last word of system
  with the first word of text under .split()).
- tests/llm/test_openai_client_confinement.py:47 — glob("*.py") →
  rglob("*.py") so the confinement scan catches openai-mentioning
  ignore directives in any future nested signalforge/llm/ subpackage,
  not just top-level files. Path display becomes relative-to-_LLM_DIR.
- tests/test_audit_completeness.py:1080 — closed the "call-before-
  import alias" bypass on _AttributeCallFinder by adding a two-pass
  visit_Module that pre-collects every alias module-wide before
  visiting any Call node. Mirrors the same fix already shipped on
  _QualifiedNameCallFinder (PR #69 / DEC-013). Pattern-4 regression
  test added.

Validation: ruff/format/pyright/pytest all green (2498 passed,
97.34% coverage); wheel_smoke green.



* #136: close PR #152 codecov gaps (9 lines → 0)

Codecov flagged 91.82% patch coverage with 9 lines missing across
3 files. Closed all 9 with 6 focused unit tests:

src/signalforge/llm/_openai_client.py (was 85%, now 100%):
- _OpenAIClientAdapter.__init__ + ._messages_create — no production
  caller exercises the adapter (orchestrator drives via
  FakeOpenAIClient which has its own .messages.create); added
  test_openai_client_adapter_messages_create_delegates_to_chat_completions
  that builds a SimpleNamespace raw client and pins the delegation
  + kwargs forwarding.
- _count_openai_tokens cl100k_base fallback (DEC-012 unknown-model
  branch) — added test_count_openai_tokens_falls_back_to_cl100k_base_
  for_unknown_model.

src/signalforge/llm/providers.py (was 98%, now 100%):
- AnthropicProvider.estimate_input_tokens no-system-kwarg arm (the
  else branch added in QG) — added test_anthropic_provider_estimate_
  input_tokens_skips_system_kwarg_when_empty, which ALSO pins the
  load-bearing invariant that an empty system MUST be omitted from
  the SDK kwargs (otherwise the count carries a spurious system=""
  block).
- LLMResponseFormatError raise on missing input_tokens — added
  test_anthropic_provider_estimate_input_tokens_raises_on_missing_
  input_tokens.
- OpenAIProvider.extract_text_blocks missing-message arm — added
  test_openai_provider_extract_text_blocks_missing_message_attr_
  raises (distinct from the existing content=None and empty-choices
  cases — those exercise different arms).

src/signalforge/cli/generate.py:846 (was 66%, now covered):
- The non-Anthropic `client = None` branch in cmd_generate's
  --estimate short-circuit — exercised only by the
  @pytest.mark.openai live smoke before. Added test_generate_
  estimate_openai_provider_passes_client_none_to_engine that drives
  cmd_generate with llm.provider: openai + grade.provider: openai
  in a tmp signalforge.yml, spies on AnthropicProvider.make_client
  to confirm it's NEVER called on the openai path, and captures the
  client kwarg into estimate(...) to pin client=None. The remaining
  7 uncovered lines in generate.py are pre-PR and out of scope.

Total: 2504 passed (was 2498), 97.47% coverage (was 97.34%), no
new gated tests added (all unit tests, default-CI-included).



---------



* #137: Gemini grading provider (plan) (#151)

* #137: Gemini grading provider (plan)

Super plan for #137 (Gemini grading provider) — depends on #135 (merged).
9 stories: shim + provider + extra + fake/unit + neutrality + live +
docs + QG + P&M. Caching deferred (both capability flags False);
safety-filter no-content surfaces as LLMResponseFormatError →
grade GradeLLMError degrade. Both drafter and grader covered.



* #137: extend plan after comparison with #136 OpenAI plan

Closes the three gaps surfaced by the #136 comparison:

- Add --estimate integration (DEC-016): GeminiProvider.estimate_input_tokens
  via native client.models.count_tokens (cleaner than #136's tiktoken path —
  Gemini has a first-party count endpoint).
- Add 3 Gemini pricing SKUs to pricing.py (DEC-017): gemini-2.5-pro,
  gemini-2.5-flash, gemini-2.0-flash; bump PRICE_TABLE_VERSION.
- Add server-side JSON enforcement (DEC-018): response_mime_type=
  application/json — mirrors #136 DEC-006.
- Add CHANGELOG entry to docs story (US-009).
- Add wheel_smoke to QG (new [gemini] extra changes packaging).
- Sequence after #136 (DEC-019): inherit ABC extension + estimate refactor.

New stories: US-006 (pricing, parallel-safe), US-007 (estimate impl,
depends on #136). Old US-006/007 renumbered to US-008/009.



* #137: apply 3 plan refinements from #136 cross-review

Closes the smaller gaps surfaced by re-reviewing #137 against #136 after
the #136 plan was tightened (520b36c):

1. DEC-009 — merge-order-conditional AST scan tally. Currently said "8 → 9"
   unconditionally, but DEC-019 specifies #137 ships AFTER #136. Realistic
   bump is 9 → 10 (since #136's openai.OpenAI scan bumps 8 → 9 first);
   added the fallback wording for the slipped-sequencing case.
2. Dedicated "Worker-writability routing" top-level section codifying that
   Patterns & Memory is orchestrator-only (.claude/rules/ writes). Was a
   one-line architecture-review row; now a durable section that mirrors
   #136's codification — future #138+ provider plans copy the pattern.
3. Open notes for implementation — two additions:
   - response_mime_type requires NO prompt keyword (contrast with OpenAI's
     response_format which fails without "json" in prompt). Prevents a
     future maintainer adding defensive prompt text.
   - pricing.lookup zero cache fields math validation (symmetric to #136
     verification item).

Major gaps from the prior cross-review (--estimate, pricing, dual-listing,
JSON enforcement, CHANGELOG, three live tests, sequencing) were already
addressed in b28c0b5.



* #137: devolve plan to beads (phase=devolved)

Epic: bd_1-scaffolding-txe
Tasks: 11 (US-001 through US-009 + Quality Gate + Patterns & Memory)
Dependencies: 19 edges per the plan's dependency graph
Ready queue: US-001 (shim) + US-006 (pricing, parallel-safe)

US-007 (--estimate integration) is blocked on US-002 + US-006 AND
carries a cross-epic gate on #136 landing first per DEC-019 — that
sequencing is documented in the task's description rather than wired
as a bead dep since #136's beads live in a different epic.

US-011 (Patterns & Memory) is flagged orchestrator-only because it
edits .claude/rules/ which Ralph workers can't write under in
worktrees (per the Worker-writability routing section of the plan).



* #137: adjust plan now that #136 is being implemented first

Folds devolve-time annotations (phase=devolved, beads epic
bd_1-scaffolding-txe, per-task status + cross-epic blocker on US-007)
together with five #136-driven adjustments:

1. AST-scan tally locked to 10th (not 9th) — #136 owns the 8→9 bump
   for openai.OpenAI; #137 takes 9→10 for genai.Client. Updated in
   DEC-009, US-001, P&M, and Open notes.
2. DEC-019 sharpened: #136 plan → #136 implementation; explicit rebase
   guidance (rebase on dev after #136 merges) rather than contingency
   wording.
3. DEC-005 gains a refusal/content-filter symmetry note cross-ref'ing
   #136 DEC-014 — explains why OpenAI deliberately ships no
   safety-filter typed-degrade and why Gemini deliberately does.
4. New "Worker-writability routing" section mirroring #136's, codifying
   that P&M is orchestrator-only because it edits .claude/rules/.
5. Open notes extended with two pragmatic items parallel to #136's:
   - google-genai count_tokens response field-name verification
     (.total_tokens vs .total_token_count) at US-007 implementation.
   - Anthropic byte-identity snapshot ownership: #136 owns it; #137
     inherits it; the wiring is wrong if it moves the snapshot.

Plan grows 762 → 825 lines (+70/-30).



* bd_1-scaffolding-txe.6: #137 US-006 — add Gemini pricing SKUs (gemini-2.5-pro, gemini-2.5-flash, gemini-2.0-flash)

Adds three Gemini SKUs to _PRICES_MUTABLE per DEC-017, each with positive
input_per_mtok / output_per_mtok per Google's public Gemini API price page
and cache fields = 0.0 (v0.3 ships Gemini without an Anthropic-equivalent
prompt-cache discount). Bumps PRICE_TABLE_VERSION to "2026-05-27". Tests
parametrise the three SKUs, pin Anthropic SKU byte-identity (additive-only),
and assert lookup("gemini-unknown") still raises EstimateUnknownModelError.

cli/_estimate.py reads only input_per_mtok and output_per_mtok in the USD
math (lines 468, 511), so zero cache fields are safe — no divide-by-zero
or NaN risk. The EstimateUnknownModelError.default_remediation in
llm/errors.py still lists only the three Claude SKUs by name; per the
story scope ("pricing-only; DO NOT touch any other file") this is left
for a follow-up to broaden once the wider Gemini surface (provider class
+ --estimate integration in US-007) lands.



* bd_1-scaffolding-txe.1: #137 US-001 — _gemini_client.py shim + new AST confinement scan

Land the per-vendor Gemini SDK shim and the 9th AST audit-completeness
scan that confines genai.Client(...) constructions to it. Mirrors the
Anthropic shim shape verbatim — GeminiClientProtocol (with .messages
façade for US-002 and .models for US-007), lazy-import factory, frozen
_GeminiExceptionClasses dataclass with empty-tuple fallback per DEC-015
so the module imports cleanly without the [gemini] extra installed.

The new scan extends _AttributeCallFinder with an optional parent_module
parameter so the namespace-package shape `from google import genai;
genai.Client(...)` is caught alongside `from google.genai import Client`
and its alias variant — five planted-violation regression tests pin the
three bypass patterns plus a negative case and an Anthropic-path-unchanged
guard. A line-based confinement test
(tests/llm/test_gemini_client_confinement.py) rejects any
google.genai-mentioning `# type: ignore` outside the shim, mirroring
tests/warehouse/test_snowflake_client_confinement.py. The existing
Anthropic shim's regex-level confinement test narrowed from "any
ignore" to "anthropic-mentioning ignore" so the new Gemini shim's own
SDK ignores don't trip it. All four canonical validation steps pass;
2474 tests; coverage 97.33%.



* bd_1-scaffolding-txe.3: #137 US-003 — pyproject.toml [gemini] extra + dev-group sync

google-genai>=0.5,<1 listed in three pyproject slots in lockstep per DEC-010
(operator install, pip dev back-compat, uv dev group). uv.lock regenerated.



* bd_1-scaffolding-txe.2: #137 US-002 — GeminiProvider(LLMProvider) + registration

GeminiProvider concrete strategy registered at module import; both capability
flags False per DEC-003. build_create_kwargs sets response_mime_type=
application/json (DEC-018) and maps system → system_instruction + single user
turn (DEC-004). Safety-blocked / no-content responses → LLMResponseFormatError
per DEC-005. Exception taxonomy per DEC-006 — verified against
google-genai==0.8.0.

Notes from verification against the installed SDK:

- google.genai.errors.APIError (the shared parent of ClientError +
  ServerError) stores the HTTP code on .code (an int), not .status_code —
  the classifier reads .code. ClientError covers 4xx (incl. 401/403/429);
  ServerError covers 5xx. ServerError is checked BEFORE ClientError so the
  narrower 5xx bucket cannot be shadowed by a future shared parent class.

- The SDK's models.generate_content(config=) accepts both
  GenerateContentConfig and the plain-dict GenerateContentConfigDict form.
  build_create_kwargs returns the plain-dict form so providers.py never
  imports google.genai.types at any scope — keeping
  test_gemini_client_confinement.py green and base-install module-import
  clean.

- The .messages.create façade required by the orchestrator is wired in
  GeminiProvider.make_client via a small _GeminiClientAdapter /
  _GeminiMessagesAdapter pair (the shim returns the bare client; US-002
  owns the adapter per the shim's docstring). The adapter forwards
  **kwargs straight to client.models.generate_content / count_tokens.

- Connection-flavoured exceptions (httpx.ConnectError /
  httpx.TimeoutException) leak through the SDK on hard network failures;
  the classifier handles them with a lazy httpx import and an
  ImportError-safe fallback to NO_RETRY.

Updates the pinned signalforge.llm __all__ surface in
tests/llm/test_public_api.py and tests/draft/test_schema.py to include the
new GeminiProvider re-export; adds DraftConfig/GradeConfig provider="gemini"
acceptance tests.



* bd_1-scaffolding-txe.9: #137 US-009 — operator-facing docs + CHANGELOG for Gemini

docs/grade-ops.md + docs/draft-ops.md register gemini as a provider, name the
[gemini] install extra + GOOGLE_API_KEY env var, and document the v0.3
no-caching cost note (DEC-013). README provider list deferred (no list exists
to extend). CHANGELOG entry under [Unreleased]. .claude/rules/* deferred to
Patterns & Memory (orchestrator-only).



* bd_1-scaffolding-txe.4: #137 US-004 — FakeGeminiClient + offline provider integration tests

Hand-rolled FakeGeminiClient mirrors FakeAnthropicClient's expect_* API
(DEC-011). New tests/llm/test_fake_gemini.py proves the fake's contract;
tests/llm/test_gemini_provider_via_fake.py drives GeminiProvider through
the fake end-to-end (call_llm round-trip, safety-blocked branch, retry
exhaustion).



* bd_1-scaffolding-txe.5: #137 US-005 — provider-neutrality e2e tests (draft + grade)

tests/grade/test_gemini_neutrality.py drives grade_artifacts end-to-end through
FakeGeminiClient: cache_*=0 in JSONL, blake2b-8 hashes, sidecar round-trip, no
dual-zero WARNING (DEC-003), safety-blocked → GradeLLMError degrade (DEC-005).
tests/draft/test_gemini_neutrality.py drives draft_schema end-to-end likewise.
DEC-014 two-stage scope satisfied at the offline-test layer.



* bd_1-scaffolding-txe.8: #137 US-008 — gemini marker + live tests (raw + draft + grade) + CONTRIBUTING

@pytest.mark.gemini marker registered; addopts excludes it from default CI per
DEC-012. Three live smokes gated SF_RUN_GEMINI=1 + GOOGLE_API_KEY:
test_gemini_live.py (raw call_llm), test_gemini_draft_live.py (draft_schema),
test_gemini_grade_live.py (grade_artifacts 1-criterion × 1-artifact).
CONTRIBUTING.md adds the maintainer 'uv run pytest -m gemini --no-cov' entry
alongside the existing snowflake/anthropic equivalents. --estimate live test
deferred to US-007 (gated on #136).



* #137: harden DEC-019 cross-epic gate via bd sentinel bead

DEC-019 was documentary only; bd_1-scaffolding-txe.7 (US-007) showed
as bd-ready despite the plan saying "wait for #136 to merge to dev."
A Ralph worker running `bd ready` would have picked it up and
rebase-fought #136 on providers.py / pricing.py / cli/_estimate.py
exactly as DEC-019 warns against.

Created sentinel bead bd_1-scaffolding-41a ("#136 OpenAI grading
PR #152 merged to dev") and wired bd_1-scaffolding-txe.7 to depend on
it. `bd ready` no longer surfaces US-007 until the sentinel closes.
Close the sentinel the moment #136 merges to dev → US-007 unblocks
automatically.

Updated DEC-019 + the beads manifest entry on US-007 to point at the
sentinel.



* bd_1-scaffolding-txe.7: #137 US-007 — GeminiProvider.estimate_input_tokens + --estimate integration

Replaces the merge-resolution NotImplementedError stub with a real
implementation via Gemini's native client.models.count_tokens
(first-party; no tiktoken equivalent). The --estimate cost-preview
path now works end-to-end for grade.provider: gemini and
llm.provider: gemini. Anthropic byte-identity golden unchanged
(verified against tests/fixtures/estimate/anthropic_byte_identity_golden.txt).



* bd_1-scaffolding-txe.10: #137 Quality Gate — fix bugs from 4-reviewer pass

Four parallel code-review passes surfaced 2 substantive code findings
and 5 documentation findings; all fixed below. CodeRabbit run skipped
(no skill available locally); maintainer can request post-merge.

Code fixes (reviewer 2 — tests):

- tests/test_audit_completeness.py: added the missing planted-violation
  regression test for the new parent_module codepath in
  _AttributeCallFinder. Covers Patterns 5-8 (namespace-package via
  from-google-import-genai, namespace alias, dotted-from-import,
  dotted-import-as) plus a negative check pinning that Pattern 7
  requires parent_module to be set. Mandated by testing-signal.md
  § "AST single-construction-seam scans must catch all three bypass
  patterns" — without this, a refactor of the parent_module branches
  could silently break Scan 10 at the exact moment a real Gemini-SDK
  construction was added outside _gemini_client.py.
- tests/grade/test_gemini_grade_live.py: added cache_*=0 assertion on
  every GradeEvent record (DEC-003 of #137). The docstring claimed
  this was tested but the assertion was missing — a grade-path
  bookkeeping regression would have slipped through the live smoke.

Doc fixes (reviewer 3 — docs):

- docs/grade-ops.md + docs/draft-ops.md: rewrote the "--estimate
  integration (deferred)" sections to reflect that US-007 SHIPPED in
  this PR. Both now describe the active behaviour (native
  client.models.count_tokens round-trip; failures surface as
  <unavailable>) instead of the pre-US-007 deferred state.
- CHANGELOG.md: updated the Gemini Unreleased bullet to advertise
  --estimate support as part of the #137 deliverable; reserved the
  "follow-up" framing for explicit Gemini context caching only.
- docs/cost-estimate-ops.md: added Gemini coverage in three places —
  the provider-aware token counting bullet list, a parallel "Gemini
  provider — [gemini] install extra" section (with the three
  registered SKUs in a table), and the maintainer live smoke set.
  File had ZERO Gemini coverage before this fix.
- README.md: added Google Gemini to the supported-providers section
  alongside Anthropic + OpenAI; moved the Gemini roadmap row from
  "Planned v0.4" into "Shipped v0.4" since it's landing in this PR.

Reviewer 1 (providers.py) and reviewer 4 (packaging + integration)
reported 0 bugs. Reviewer 2's LOW-priority findings (flake-prone
aggregate_complete assertion, loose substring on confinement scan,
missing 5xx-retry integration test) deferred — not correctness risks.

Validation after fixes:
- ruff check: passed
- ruff format --check: passed
- pyright: 0 errors, 0 warnings, 0 informations
- pytest: 2555 passed, 65 deselected, 97.51% coverage
- wheel_smoke: 2/2 passed (new [gemini] extra packaging intact)
- Anthropic byte-identity golden: passed (unchanged)



* bd_1-scaffolding-txe.11: #137 Patterns & Memory — durable rules for Gemini

Orchestrator-only commit (Ralph workers can't write under .claude/ in
worktrees per memory ralph-worker-claude-dir-perms.md).

.claude/rules/llm-drafter.md:
- AST scan tally bumped 5 → 6 (Scan 10 = genai.Client confinement
  via _AttributeCallFinder(parent_module="google")).
- New § "Gemini provider shape (#137 — the third concrete provider,
  no-cache via a namespace-package SDK)" with the four load-bearing
  patterns: .messages-over-.models.generate_content adapter,
  response_mime_type=application/json server-side JSON enforcement,
  safety-filter typed LLMResponseFormatError → grade degrade, and
  native models.count_tokens for --estimate (distinct from OpenAI's
  local tiktoken path).
- New § "Namespace-package SDKs (#137 generalisation)" documenting
  the parent_module parameter that catches the four namespace-package
  import shapes the no-parent path misses.
- Reference block extended with the #137 plan + the three new fakes
  + the two new neutrality test suites.
- "new vendor lands" wording generalised (#137 is no longer "next",
  it's "shipped"); Anthropic→OpenAI→Gemini lineage noted explicitly.

.claude/rules/grade-layer.md:
- Conservative degrade taxonomy DEC-002/DEC-015 entry for
  GradeLLMError extended with a sentence explaining Gemini's
  safety-filter / no-content response routes through the same path
  via the typed LLMResponseFormatError that GeminiProvider raises
  (DEC-005 of #137). Locks in the provider-neutral contract: a
  future vendor with a content-filter surface MUST route through
  LLMResponseFormatError, not a provider-specific switch in
  grade_artifacts.



* #137: Address PR review feedback (Copilot + CodeRabbit)

Five real issues fixed; three outdated threads resolved as-is.

Fixed:

1. src/signalforge/llm/_gemini_client.py — Copilot flagged that
   GeminiClientProtocol's docstring claimed the bare SDK client
   satisfies it, and _make_gemini_client was annotated to return
   GeminiClientProtocol despite returning the raw google.genai.Client
   (which has no .messages namespace). The protocol is satisfied only
   by the wrapped _GeminiClientAdapter (in providers.py) and by the
   test fake. Rewrote both docstrings; relaxed _make_gemini_client's
   return type to `Any` and explained the wrapper-on-top contract
   explicitly. Replaces the misleading "satisfies structurally" claim
   with the honest "bare SDK does NOT satisfy; wrapper does."

2. plans/super/137-gemini-grading.md (Discovery, line 98) — CodeRabbit
   flagged the stale PRICE_TABLE_VERSION = "2026-05-11". Annotated
   the reference as "at discovery time" and noted that US-006 and
   #136 both bump it.

3. plans/super/137-gemini-grading.md (Worker-writability routing) —
   CodeRabbit flagged a duplicated "## Worker-writability routing"
   heading. The duplicate must have crept in during the cross-review
   pass. Removed the second copy; kept the first canonical version.

4. tests/llm/test_pricing.py
   (test_lookup_raises_estimateunknownmodelerror_for_unknown_gemini_model)
   — CodeRabbit flagged that the test only validates `.model`,
   leaving the operator-facing remediation text drifting silently
   from the pricing table. Added a structural pin that the rendered
   exception names every Gemini SKU. Future SKU additions force a
   lockstep remediation update.

Outdated threads (3) — content already fixed by earlier commits; the
threads are kept resolved for hygiene:

5. tests/test_audit_completeness.py docstring "node.module == genai"
   note (Copilot, two threads). The actual scan handles the dotted-
   form via parent_module; the comments in the implementation
   already reflect this since the QG pass.

6. CONTRIBUTING.md pre-release excluded-marker list (CodeRabbit). The
   list was already extended to include `gemini` (and `snowflake`)
   during the QG fix in commit f15a469.

Validation after fixes:
- ruff check: passed
- ruff format --check: 279 files formatted
- pyright: 0 errors, 0 warnings, 0 informations
- pytest: 2555 passed, 65 deselected, 97.51% coverage



* #137: Address second-round PR review (Copilot, 4 new comments)

Two real findings fixed; two false positives documented.

Fixed:

1. pyproject.toml gemini marker description — Copilot flagged that
   the help text named only GOOGLE_API_KEY but the live tests also
   gate on SF_RUN_GEMINI=1. Updated to "requires SF_RUN_GEMINI=1 +
   GOOGLE_API_KEY" — mirrors the OpenAI marker's shape exactly.

2. src/signalforge/llm/providers.py::GeminiProvider.extract_usage —
   Copilot flagged that getattr(usage, "prompt_token_count", 0) or 0
   silently swallows missing/malformed SDK response shapes and feeds
   misleading 0/0 figures into the audit JSONL + --estimate math.
   Switched to the shared _extract_usage_field helper which raises
   LLMResponseFormatError on missing/non-int fields. Matches the
   Anthropic precedent (the OpenAI provider already uses the same
   helper). Added test_geminiprovider_extract_usage_missing_inner_
   field_raises pinning both the missing-field and non-int-type
   paths to keep them durable.

False positives (replied in resolve-threads):

3. _gemini_client.py:116 (`_make_gemini_client` return annotation):
   Copilot is reviewing the pre-commit-00dc673 diff. The previous
   round of fixes (commit 00dc673) already changed the return type
   to Any and rewrote the docstring to be honest that the bare SDK
   client does NOT satisfy GeminiClientProtocol; only the
   _GeminiClientAdapter wrapper does. Current file matches.

4. plans/super/137-gemini-grading.md:777 (duplicate Worker-
   writability routing): Same — the duplicate was already removed
   in 00dc673. Only one section now exists at line 757.

* #155: Gemini truncation + per-provider e2e gap (#156)

* #155: super-plan — Gemini truncation + per-provider e2e gap

12 DECs covering:
- DEC-001/002/005: provider-neutral is_clean_completion ABC method
- DEC-003/011: 2 new e2e siblings + BQ smoke parametrize
- DEC-008/009: per-provider max_output_tokens floor table (1024/1024/2048)
- DEC-010: pre-release-only cadence (~\$0.30 / suite run)
- DEC-012: apply_provider_override helper

10 stories sized for Ralph contexts. Architecture review: 1 concern (seam
design — resolved), 8 pass. Regression risk green (no fixture pins old
reasoning string; existing test_gemini_neutrality.py:381 already pins the
post-fix shape).



* #155: devolved — epic + 10 tasks live in bd

Epic: bd_1-scaffolding-eu0
Ready set: US-001 (.2), US-003 (.4), US-004 (.5) — three parallel-safe.
16 dep links wired.

Serialization callouts captured (US-005/6/7 share _e2e_helpers + BQ smoke;
US-002 + US-010 edit .claude/rules/, orchestrator-only).



* bd_1-scaffolding-eu0.4: #155 US-003 — bump Gemini live fixture to 2048 + per-provider max_output_tokens floor docs

* bd_1-scaffolding-eu0.5: #155 US-004 — apply_provider_override helper + BQ smoke uses it

Adds the canonical per-test grade-provider overlay helper. Multi-provider
e2e smokes (BigQuery+Anthropic / +OpenAI / +Gemini) share the committed
Austin fixture and swap only grade.provider/model/max_output_tokens via
this seam — no near-duplicate fixtures.

The helper is non-destructive: unset knobs left alone, sibling top-level
blocks (llm:/safety:/prune:) round-trip via yaml.safe_dump(sort_keys=False).
Missing signalforge.yml raises FileNotFoundError rather than silently
creating one (masks misconfigured tests).

Unit-tested in tests/cli/test_e2e_helpers.py — runs in the default
pytest set (no marker), so a regression in the YAML overlay plumbing the
real e2e smokes depend on trips immediately.

BigQuery smoke refactored to call apply_provider_override(project_dir,
grade_provider='anthropic') as a no-op proof-of-use; OpenAI (US-005) and
Gemini (US-006) sibling smokes will pass non-default values through the
same seam.

Traces to: DEC-012 in plans/super/155-gemini-truncation-e2e-gap.md

* bd_1-scaffolding-eu0.2: #155 US-001 — LLMProvider.is_clean_completion ABC + 3 concretes + wire-in

Add provider-neutral allowlist gate for response finish-reason / stop-reason
to prevent silent pass-through of truncated / safety-filtered / tool-use
responses (DEC-001/002/005/006/007 of plans/super/155).

- LLMProvider.is_clean_completion(response) -> bool — abstract
- LLMProvider.unclean_finish_reason_message(response) -> str — default + per-vendor overrides
- AnthropicProvider._CLEAN_STOP_REASONS = {end_turn, stop_sequence}; tool_use is UNCLEAN (DEC-006)
- OpenAIProvider._CLEAN_STOP_REASONS = {stop}
- GeminiProvider._CLEAN_STOP_REASONS = {STOP}
- call_llm wires the gate immediately before strategy.extract_text_blocks,
  raising LLMResponseFormatError (typed, non-retryable response-shape error)
  with the provider-specific diagnostic when the gate returns False.
- _DummyProvider + FakeNoCacheProvider satisfy the new abstract by
  returning True (no finish-reason concept on the canned shapes).

TDD: 4 happy-path tests added (one per concrete provider + 2 for Anthropic
covering both clean stop reasons) and confirmed failing before implementation,
then green. Canonical validation quad (ruff/format/pyright/pytest) all-green;
2560 tests pass (no regressions); AST scans 3/9/10 pass.



* bd_1-scaffolding-eu0.6: #155 US-005 — new tests/cli/test_e2e_openai_smoke.py

Full-pipeline live e2e gated by @pytest.mark.e2e + @pytest.mark.openai
markers and a three-env-var skip gate (SF_RUN_OPENAI=1, OPENAI_API_KEY,
GOOGLE_CLOUD_PROJECT — BigQuery stays the warehouse). Mirrors
tests/cli/test_e2e_bigquery_smoke.py verbatim and only swaps the grader
via apply_provider_override(grade_provider='openai', grade_model='gpt-4o')
per DEC-011/DEC-012 of plans/super/155-gemini-truncation-e2e-gap.md;
drafter stays Anthropic Sonnet per the fixture's llm.model pin and the
cost-table rationale (DEC-009).

Pins the seven invariants from the BQ smoke (DEC-009 of #10): exit 0,
sidecar present, kept+flagged+dropped>=1, always-passes drop present
(warehouse-side, provider-independent), flagged_count>=1 (tight grade
thresholds), GradingReport.aggregate_complete=True (the cross-provider
contract the in-isolation grade smokes can't pin), and no traceback in
stderr (cli-layer.md DEC-016).

Test is deselected by default addopts; maintainer runs once pre-release.



* bd_1-scaffolding-eu0.7: #155 US-006 — new tests/cli/test_e2e_gemini_smoke.py with max_output_tokens=2048 overlay



* bd_1-scaffolding-eu0.3: #155 US-002 — per-provider unclean-path tests + call_llm integration (rule edit deferred to orchestrator)

Per-provider unclean-path tests pinning the LLMProvider.is_clean_completion
contract (#155 DEC-001/DEC-002/DEC-005/DEC-006/DEC-007):

- tests/llm/test_anthropic_provider_via_fake.py: + max_tokens (with partial
  text), tool_use, unclean_finish_reason_message naming stop_reason.
- tests/llm/test_openai_provider_via_fake.py: + length (with partial text),
  content_filter, tool_calls, unclean_finish_reason_message naming
  finish_reason.
- tests/llm/test_gemini_provider_via_fake.py: + MAX_TOKENS-with-partial-text
  (the LOAD-BEARING #155 Finding 1 regression pin, with full context comment),
  SAFETY/RECITATION/OTHER parametrized, unclean_finish_reason_message naming
  finish_reason.
- tests/llm/test_client.py: + call_llm integration test asserting
  LLMResponseFormatError raises at the is_clean_completion gate
  (post-messages.create, pre-extract_text_blocks, no retry).

Existing contract pin tests/grade/test_gemini_neutrality.py:381 continues
to pass unmodified — the safety-blocked Gemini path now routes through the
same orchestrator gate as MAX_TOKENS, both landing at
'call failed: GradeLLMError' degrade.

Note: .claude/rules/llm-drafter.md edit deferred — per memory
ralph-worker-claude-dir-perms, .claude/ writes are orchestrator-only and
will land in a separate commit after this merge.



* bd_1-scaffolding-eu0.8: #155 US-007 — parametrize tests/cli/test_e2e_bigquery_smoke.py over grade.provider

Adds @pytest.mark.parametrize over grade_provider ∈ [anthropic, openai,
gemini] to the BigQuery e2e smoke test. Per #155 DEC-003 this covers
the cross-provider diff-sidecar rendering contract the in-isolation
grade smokes (tests/grade/test_*_grade_live.py) cannot pin: those
smokes never exercise the diff-sidecar evidence/reasoning cascade with
a non-Anthropic judge.

Per #155 DEC-011 the drafter stays Anthropic Sonnet across all three
variants (fixture stability — the LLM payload the drafter sees is
unchanged, so the always-passes column the LLM proposes is
reproducibly the same). Only the grader varies, via the canonical
apply_provider_override helper (US-004 / DEC-012).

Per-variant env-var gates layered on top of the existing baseline:
  - anthropic: baseline only (SF_RUN_BQ + ANTHROPIC_API_KEY + GOOGLE_CLOUD_PROJECT)
  - openai:   baseline + SF_RUN_OPENAI + OPENAI_API_KEY
  - gemini:   baseline + SF_RUN_GEMINI + GOOGLE_API_KEY

Gemini variant pins max_output_tokens=2048 per #155 Finding 2 — Gemini
2.5-flash's verbose reasoning field truncates mid-string at the
default 512/1024 floors and would flake assertion #6 (aggregate_complete).

Sibling files (test_e2e_openai_smoke.py / test_e2e_gemini_smoke.py)
remain per DEC-011 for per-provider failure ergonomics and cost
transparency; this parametrize is internal to the BQ smoke.

Pytest IDs: test_*[anthropic] / test_*[openai] / test_*[gemini]. All
three are deselected by default addopts (gated by the e2e marker);
the maintainer runs them per pre-release live suite (US-008).

Validation: uv sync --dev && ruff check && ruff format --check &&
pyright && pytest — all green (2566 passed, 69 deselected, coverage
97.40%).

* bd_1-scaffolding-eu0.3: #155 US-002 (orchestrator portion) — clarify llm-drafter.md DEC-005 for the is_clean_completion seam

Updates the Gemini-section DEC-005 contract to reflect the post-#155 generalisation:
- Rule now applies to ALL providers (Anthropic stop_reason, OpenAI choices[0].finish_reason,
  Gemini candidates[0].finish_reason.name) — not just Gemini
- Enforcement moved from "no text at all" check buried in extract_text_blocks to the new
  LLMProvider.is_clean_completion(response) -> bool ABC method (#155 DEC-005)
- Closes the Finding-1 gap: MAX_TOKENS with partial text now surfaces as
  LLMResponseFormatError → GradeLLMError, not GradeOutputError(json_parse)
- Per-provider _CLEAN_STOP_REASONS enumerated; tool_use deliberately UNCLEAN per DEC-006
- unclean_finish_reason_message override (DEC-007) keeps vendor-native field names visible

Test-side pins (worker portion of US-002, commit 9a23e3f):
- tests/llm/test_{anthropic,openai,gemini}_provider_via_fake.py — unclean-path coverage
- tests/llm/test_client.py — call_llm gate integration

Worker (commit 9a23e3f) deferred this rule edit per memory ralph-worker-claude-dir-perms;
this commit closes the bead's orchestrator-only deliverable.



* bd_1-scaffolding-eu0.9: #155 US-008 — CONTRIBUTING.md live-suite pre-release cadence + env-var block

Add a 'Live e2e suite (pre-release only)' subsection to CONTRIBUTING.md
per DEC-010 of plans/super/155-gemini-truncation-e2e-gap.md.

Documents the full pre-release maintainer audit:
- 5 paid e2e tests (BQ smoke parametrized over 3 grader providers per
  US-007, OpenAI sibling, Gemini sibling with max_output_tokens=2048
  floor per DEC-008, Snowflake sibling)
- 6 grade-only / draft-only live-API smokes gated by anthropic /
  openai / gemini markers
- One-shot invocation with -m 'e2e or anthropic or openai or gemini'
  --no-cov and the full env-var stack (SF_RUN_*, ANTHROPIC_API_KEY,
  OPENAI_API_KEY, GOOGLE_API_KEY, GOOGLE_CLOUD_PROJECT, SNOWFLAKE_*)

Frames the cadence as pre-release only — NOT per-PR, NOT CI-gated. The
addopts exclusion in pyproject.toml already keeps these out of default
runs; this section just documents the maintainer-side invocation when
cutting a release. Cost ceiling: ~$0.30/run × ~2–3 audits/month =
~$0.60–1.00/month.



* bd_1-scaffolding-eu0.10: #155 US-009 — Quality Gate fixes (4-pass code review)

Pass 1 (correctness): 0 real bugs. 2 doc-drift fixes:
- docs/grade-ops.md floor table: pre-fix GradeOutputError narrative

- tests/cli/test_e2e_gemini_smoke.py invariant-#6 comment: same update

Pass 2 (simplification): 0 refactors needed.

Pass 3 (test coverage): 0 critical gaps. 3 nice-to-have safety nets added:
- tests/llm/test_gemini_provider_via_fake.py — new orchestrator wire-in pin
  for MAX_TOKENS+partial-text via call_llm (distinct from existing
  SAFETY-only call_llm test)
- tests/llm/test_openai_provider_via_fake.py — new orchestrator wire-in pin
  for length+partial-text via call_llm (no prior call_llm coverage)
- tests/grade/test_gemini_neutrality.py:381 — docstring comment binding the
  existing safety-blocked pin to the new #155 MAX_TOKENS routing path

Pass 4 (rules compliance): 1 real rule violation + 1 multi-surface drift

* #141: SignalForge skill + install-skill (plan)

Phase 4 detailing complete. 24 decisions locked across:
- skill source path (`src/signalforge/skills/signalforge/` package-data tree;
  `src/signalforge/skill/` Python lib)
- destination policy (always overwrite SKILL.md, preserve siblings, no --force)
- symlink/cycle defence (mirrors copy_demo verbatim)
- error hierarchy (SkillError base + 3 concretes; spans tiers 1+2 → excluded base)
- wheel packaging + wheel_smoke gate
- AST scan #7 bump (12→13)
- SKILL ↔ CLI parity gate (new test scans live argparse + key demo commands)
- 5-surface parity for install-skill
- self-grade ops (pre-release manual; pinned in eval.json + README badge)
- e2e demo paths (zero-cred default + opt-in live)
- skill-parity.md rule + cli-layer.md update (orchestrator-only)

11 stories laid out: US-001…US-009 implementation + US-010 Quality Gate + US-011

the skills tree. Extends wheel_smoke with _EXPECTED_SKILL_FILES (positive) and

* bd_1-scaffolding-ezn.2: US-002 signalforge.skill lib + typed errors + AST scan #7 bump

Adds signalforge.skill subpackage with install_skill(dest) -> Path and the
three-class typed-error hierarchy (SkillDestPathError tier 1, SkillDestUnsafeError
tier 2, SkillPackageDataMissingError tier 1). Mirrors signalforge.demo.copy_demo
verbatim for symlink-cycle defence and importlib.resources lookup; never rmtree.

Registers the three lib concretes in _EXCEPTION_TO_EXIT_CODE; adds SkillError to
_EXCEPTION_MAPPING_EXCLUDED_BASES; bumps AST scan #7 count 12 -> 13.

Adds 'signalforge install-skill [<dest>]' wired via add_parser/cmd_install_skill
mirroring init_demo shape. Three CliInstallSkill*Error wrappers (Path/DestUnsafe/
PackageDataMissing) registered in _EXCEPTION_TO_EXIT_CODE (tier 1/2/1). Stdout
success line + (replaced existing SKILL.md) on overwrite per DEC-017. Subprocess
--help smoke under cli_subprocess marker. Per-class construction branches added
to test_exit_codes.py for the three new wrappers.

* bd_1-scaffolding-ezn.7: US-007 author SKILL.md prose (frontmatter + 7 body sections)

Replaces the US-001 placeholder with the real user-facing workflow per DEC-020
(frontmatter) and DEC-021 (seven sections). Body teaches the full pipeline:
point-at-project, zero-cred demo, real draft+prune, prune-existing,
diff-reading, gated live e2e, troubleshooting. Contains every canonical token
the US-004 parity gate scans for (subcommand names + demo command lines +
install-skill bootstrap).

* bd_1-scaffolding-ezn.4: US-004 SKILL ↔ CLI parity gate

NEW tests/cli/test_skill_cli_parity.py scans src/signalforge/skills/signalforge/
SKILL.md for three token categories per DEC-015:
1. Every subcommand name from the live argparse parser (auto-grows)
2. Four canonical demo command lines (signalforge init-demo / generate <model>
   --write / prune-existing <model> --schema <path> / install-skill)
3. The install-skill bootstrap line (covered by category 2's fourth entry)

Plain substring match; no normalisation. Planted-violation self-check proves
the gate can fail loud — per testing-signal.md AST-source-scan-gate philosophy.

The gate runs inside the canonical VALIDATE_CMD (uv run pytest) so /ralph-run
keeps the skill current automatically without relying on the model remembering.

* bd_1-scaffolding-ezn.9: US-009 skill-parity.md + cli-layer.md update

Replaces the anticipatory skill-parity.md with the post-implementation
contract: names the actual shipped artefacts (src/signalforge/skill/,
src/signalforge/skills/signalforge/SKILL.md, signalforge install-skill,
tests/cli/test_skill_cli_parity.py), documents the two-name convention
(skills/ plural for package-data vs skill/ singular for the Python lib),
the planted-violation self-check, and the wheel exclusion defence for
maintainer-only .claude/skills/.

cli-layer.md § Multi-surface parity gains a paragraph naming the bundled
skill as the 6th parity surface, cross-linking to skill-parity.md and the
test_skill_cli_parity.py gate.

ORCHESTRATOR-ONLY commit per ralph-worker-claude-dir-perms memory —
workers cannot Write under .claude/ in worktrees.

* bd_1-scaffolding-ezn.6: US-006 docs (skills.md + mkdocs nav + cli-ops + README pointer)

NEW docs/skills.md catalog page describing the bundled SignalForge skill, the
install-skill subcommand, the two demo paths (zero-cred default + opt-in live
e2e), the parity gate, and the maintainer-only-skill exclusion. mkdocs.yml nav
gains 'Claude Code Skill' entry. docs/cli-ops.md gains the install-skill
subcommand entry with stderr shapes + exit codes. README Quick start gains a
one-sentence pointer after pip install.

clauditor badge intentionally NOT added here — US-008 owns that surface.

* bd_1-scaffolding-ezn.5: US-005 5-surface parity test for install-skill

Mirrors tests/cli/test_5_surface_parity_init_demo.py for the install-skill
subcommand. v0.1 canonical token: 'install-skill' (no flags). Pins the token
across argparse help, handler docstring, docs/cli-ops.md, plan document, and
the test docstring itself.

Orthogonal to test_skill_cli_parity.py (US-004): that scans the FULL CLI
surface against ONE skill body; this pins ONE subcommand across FIVE surfaces.

* bd_1-scaffolding-ezn.8: US-008 clauditor self-grade + README badge

Adds clauditor-eval to [dependency-groups].dev (PyPI dist name; provides
the 'clauditor' CLI entry point — the upstream LLM-as-judge framework
SignalForge's own grading layer shares its methodology with). Grade
pending — clauditor-eval installs cleanly and 'uv run clauditor grade'
runs, but a meaningful score requires a maintainer-crafted EvalSpec
(SignalForge-specific assertions + grading criteria); the auto-scaffolded
'clauditor init' template is generic boilerplate that would grade
noise-against-noise. Refined assets/SKILL.eval.json to a
'pending-first-grade' shape that pins the current signalforge.__version__,
names the grader and regen command, and explains why the maintainer must
hand-tune an EvalSpec before the first real grade. README shields.io
badge surfaces the pending state ('clauditor: pending', lightgrey). New
'Self-grade' section in docs/skills.md documents the regen flow for the
maintainer's pre-release workflow per DEC-014.

VALIDATE_CMD green: 2745 passed, all four checks. wheel_smoke + cli_subprocess
gated markers also green.

* bd_1-scaffolding-ezn.10: Quality Gate — fix bugs from code review

Four code-review passes surfaced 8 real findings; this commit addresses them.

CORRECTNESS
- src/signalforge/__init__.py: revert __version__ from 0.4.0.dev0 back to
  0.5.0.dev0 — the dev branch is the 0.5.0 development line; the previous
  value was a stale-rebase artifact (Review 1).
- src/signalforge/skill/__init__.py: extend symlink defence (DEC-005) to
  cover every install-tree ancestor (.claude/, .claude/skills/,
  .claude/skills/signalforge/) — not just SKILL.md itself. A symlinked
  ancestor dir would otherwise smuggle writes through copytree (Review 1).
- tests/skill/test_install.py: new test_install_skill_refuses_when_install_dir_ancestor_is_symlink
  pins the ancestor-symlink defence with a concrete attacker-elsewhere
  repro.

SKILL.md PROSE (drift between skill and live CLI surface)
- Remove the "--force" example (DEC-003 explicitly forbids the flag;
  re-running install-skill overwrites SKILL.md by default and preserves
  siblings).
- Frontmatter signalforge-version: "0.X.Y" → "0.5.0.dev0" (matches
  __version__; was a literal placeholder shipped to operators).
- Section 2: "no warehouse, no API keys, no dbt profile" was misleading
  — the drafter always calls Anthropic. Reword to "no dbt profile / no
  warehouse credentials of your own" + name the ANTHROPIC_API_KEY
  requirement.
- LLMCacheTooLargeError mis-labelled tier-3 → corrected to tier-2 (the
  cache-too-large check is a pre-LLM-call input-validation gate per
  cli-layer.md's four-tier taxonomy).

docs/skills.md DRIFT
- Canonical-commands list said "signalforge --version" — DEC-015's
  hardcoded list is init-demo / generate <model> --write /
  prune-existing <model> --schema <path> / install-skill (no --version
  variant; the parity gate scans for `version` subcommand separately
  via category 1).
- "signalforge --version is the first thing it runs" → "signalforge
  version (the subcommand)" — flag vs subcommand mismatch.

PARITY GATE EXTENSION (the gate would have caught the --force bug)
- tests/cli/test_skill_cli_parity.py: add fourth category that scans
  SKILL.md for `signalforge <subcommand> --<flag>` patterns and
  asserts each flag exists on the live subparser. Pinned with the
  same planted-violation philosophy (verified manually:
  reinstating --force fails the gate loud). Closes the "skill prose
  teaches a flag that doesn't exist" failure mode the original gate
  could not catch.

- uv run ruff check . — clean
- uv run ruff format --check . — clean
- uv run pyright — 0 errors

Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

* #141: close codecov patch-coverage gaps (5 lines, 3 files → 100%)

codecov flagged 5 missed lines in the PR diff:
- src/signalforge/cli/install_skill.py:177-178 — except OSError around the
  existed_before probe (silently downgrades on probe failure; the install
  should still proceed)
- src/signalforge/skill/__init__.py:150 — resolve(strict=False) fallback
  for a dest that doesn't exist yet (the common fresh-project case)
- src/signalforge/skill/__init__.py:157 — non-ELOOP OSError raw re-raise
  (narrow ELOOP-only routing is load-bearing — a PermissionError must
  NOT be mis-attributed as a symlink cycle)
- src/signalforge/skill/errors.py:66 — SkillError.__str__'s no-footer
  branch (when neither remediation kwarg nor default_remediation is set)

Per the qg-pass-3-defer-defensive-tests-fails-codecov memory, codecov
holds patch coverage to project standard regardless of "is this a real
bug today" — defensive branches need test coverage even when they're
fallbacks.

Adds 4 tests:
- test_skill_error_str_omits_footer_when_remediation_is_none (errors.py:66)
- test_install_skill_propagates_non_eloop_oserror_unchanged (skill:157)
- test_install_skill_resolves_nonexistent_dest_via_strict_false_fallback (skill:150)
- test_install_skill_handles_oserror_in_existed_before_probe (cli:177-178)

Coverage: install_skill.py 95% → 100%, skill/__init__.py 95% → 100%,
skill/errors.py 95% → 100%. Full pytest: 2751 passed (was 2747).

* #141: address CodeRabbit + Copilot PR review (13 threads)

Trivial:
- assets/SKILL.eval.json: version 0.4.0.dev0 → 0.5.0.dev0 (matches the
  __version__ revert in the previous QG commit; flagged by both reviewers).
- SKILL.md fenced ASCII pipeline diagram: add `text` language tag (MD040).
- plans/super/141: drop the leftover duplicate "_Pending Phase 3/4._"
  placeholders at the end of the doc.

Substantive — symlink defence broadened to EVERY bundled path:
- src/signalforge/skill/__init__.py: the symlink defence used to cover
  only `<dest>/.claude/skills/signalforge/SKILL.md`. A symlinked
  `assets/SKILL.eval.json` (or symlinked `assets/` directory) would
  smuggle writes through copytree. Now enumerates every relative path
  under the bundled source tree via `rglob` and refuses to overwrite any
  of them through a symlink. Pinned by
  `test_install_skill_refuses_when_assets_dir_is_symlink`.
- Also wrap `mkdir(parents=True)` in try/except NotADirectoryError →
  raise SkillDestUnsafeError so a non-dir component along the install
  chain (e.g. `<dest>/.claude` is a regular file) yields a typed
  remediation-bearing message instead of a raw OSError. Pinned by
  `test_install_skill_wraps_notadirectoryerror_from_mkdir_chain`.

Substantive — CLI existed_before probe:
- src/signalforge/cli/install_skill.py: probe was `.exists()` which
  follows symlinks AND returns False for broken symlinks. The DEC-017
  contract says "True for files and symlinks (both shapes are replaced
  from the operator's POV)" — a broken symlink is a third shape that
  the probe silently downgrades. Probe now OR's `.is_symlink()` to
  catch the broken-symlink case (semantics stay honest even though
  the lib seam then raises SkillDestUnsafeError on the same path).

Substantive — SKILL.md ADC contradiction:
- The frontmatter `compatibility:` field and Section 2 body claimed
  "zero-credential demo (no warehouse needed)" while simultaneously
  describing the demo as sampling a public BigQuery dataset under ADC
  (which requires `gcloud auth application-default login` +
  GOOGLE_CLOUD_PROJECT). Both surfaces rewritten to honestly describe
  the demo's real posture: removes the dbt-project setup cost, but
  needs ANTHROPIC_API_KEY + ADC + GOOGLE_CLOUD_PROJECT. Section 2 also
  surfaces `signalforge lint --model <name>` as the truly-offline
  fallback (manifest-only, no LLM, no warehouse).

Substantive — dbt parse invocation:
- SKILL.md Section 1 suggested running `dbt parse` but the
  `allowed-tools` frontmatter does NOT include `Bash(dbt *)`. Reworded
  to "ask the user to run dbt parse themselves" rather than implying
  the skill runs it — preserves the narrow tool grant.

Substantive — parity gate (`test_skill_cli_parity.py`):
- Broaden `_SKILL_FLAG_USAGE_RE` to match `signalforge <subcommand>
  [<positional> ...] --<flag>` so canonical shapes like `generate
  <model> --write` and `prune-existing <model> --schema <path>` are no
  longer skipped (CodeRabbit + Copilot). Constrain to same-line
  `[ \t]` (not `\s`) so the match cannot span newlines — without
  this, prose like "signalforge installed (pip install ...)" plus
  "signalforge lint --model" two paragraphs later yields a spurious
  `installed --model` capture (caught during validation).
- Unknown-subcommand branch now FAILS instead of skipping (Copilot).
  A typo like `signalforge instal-skill --force` would previously
  skip silently; now it surfaces in the assertion message.
- Verified via planted-violation: `signalforge generate <model>
  --xyzbogus` injection trips the gate; restoring SKILL.md returns
  the gate to green.

Validation:
- uv run ruff check . — clean
- uv run ruff format --check . — clean
- uv run pyright — 0 errors
- uv run pytest — 2753 passed (was 2751; +2 new tests)
- uv run pytest -m wheel_smoke --no-cov — 5/5
- Patch coverage: install_skill.py 100%, skill/__init__.py 100%,
  skill/errors.py 100% — codecov-clean.

113-120: ⚠️ Potential issue | 🔴 Critical | ⚡ Quick win

Type inconsistency: end_station_id should be INT64, not STRING.

The column end_station_id is typed as STRING (line 117), but its description (line 114) states "Numeric identifier of the station where the trip ended." This conflicts with start_station_id (line 108), which is correctly typed as INT64 and has the parallel description "Numeric identifier of the bikeshare station where the trip began."

Both station ID columns reference the same conceptual entity (bikeshare stations) and should have matching types. The STRING type for end_station_id will cause the type-coherence defence (issue #159, documented in docs/draft-ops.md) to flag legitimate comparisons like WHERE start_station_id = end_station_id as type violations.

Type inconsistency: end_station_id should be INT64, not STRING.

Same issue as in src/signalforge/_demo/target/manifest.json: end_station_id is typed as STRING but described as "Numeric identifier," while start_station_id at line 108 is correctly INT64. Both station ID columns should have matching types.

           "name": "end_station_id",
           "description": "Numeric identifier of the station where the trip ended (rider docked-in the bike). Same join semantics as `start_station_id`. NULL is possible for trips that ended outside the station network or whose end-station record was later deleted from the registry.",

update the "data_type" value for the "end_station_id" object in manifest.json

Align the stated dev-dependency sync contract with actual config.

Line 29 says the two dev lists are kept in sync, but clauditor-eval is only in [dependency-groups].dev (Line 82). Either add it to [project.optional-dependencies].dev or narrow that comment to explicitly document the exception, so pip-based contributors don’t get a surprising tool mismatch.

Clarify provider language for multi-provider support.

Lines 4 and 70 state "the drafter always calls Anthropic," but the PR summary documents multi-provider support (Anthropic, OpenAI, Gemini). If the bundled demo intentionally uses only Anthropic for simplicity, consider softening the language to "the bundled demo uses Anthropic" rather than "always calls Anthropic" to avoid confusion when users configure other providers in their own projects.

Consider moving __all__ to the end of the file for consistency.

The __all__ list is placed at lines 32-37 (before class definitions), but the sibling module src/signalforge/llm/cost/errors.py in this same PR places it at the end (lines 155-161). Python convention and the codebase pattern favor end-of-file placement for __all__.

Consider defensive validation of YAML structure.

If yaml.safe_load returns a non-dict root (e.g., the file contains - item1\n- item2), line 233's setdefault will raise AttributeError. While this is test infrastructure and the committed fixtures are well-formed, adding a check like if not isinstance(data, dict): raise ValueError(...) would produce a clearer error message for maintainers who accidentally corrupt a fixture.

Inline comments:
In `@CHANGELOG.md`:
- Around line 23-36: The changelog contains a duplicated release block for
"[0.4.0] — 2026-05-30" that is identical to the v0.5.0 section; remove the
redundant "[0.4.0] — 2026-05-30" block (the repeated header and its "Added" /
"Fixed" bullets) so only the intended v0.5.0 release remains, or if v0.4.0 must
exist replace its content with the correct historical notes — look for the
"[0.4.0] — 2026-05-30" header and its associated bullet list and delete or
replace that whole block.

In `@docs/draft-ops.md`:
- Around line 762-767: The Gemini row in the capacity table (the line beginning
"Gemini (2.5-flash+)") is marked as "pending Gemini-drafter live validation" but
sits alongside validated entries for Anthropic and OpenAI; update the docs to
avoid implying validation: either move the entire "Gemini (2.5-flash+)" row into
a new "Provisional (pending validation)" section, remove the row until live
validation completes, or add a prominent table-level note (above the table) that
explicitly states the Gemini 4096 figure is provisional; ensure the change
references the "Gemini (2.5-flash+)" row and the wording "pending Gemini-drafter
live validation".

In `@src/signalforge/cli/generate.py`:
- Around line 826-846: The code currently rejects mixed providers by comparing
draft_config.provider and grade_config.provider and raising CliInputError;
change this to allow independent providers and only construct an SDK client when
either stage needs one (e.g., if draft_config.provider == "anthropic" or
grade_config.provider == "anthropic"), removing the provider-equality guard;
create the client variable accordingly (use provider_for(...).make_client() and
cast to "AnthropicClientProtocol" when an Anthropic client is required,
otherwise set client = None) so a config like draft=openai, grade=anthropic will
still work.

In `@src/signalforge/llm/pricing.py`:
- Line 61: Update the per-token rates and version string in pricing.py: set
PRICE_TABLE_VERSION to the snapshot date you're targeting, update the OpenAI SKU
entries (gpt-4o, gpt-4o-mini, gpt-4.1, gpt-4-turbo) to the May 2026 per‑1M token
input/output prices, change gemini-2.5-flash to $0.625 input / $5.00 output per
1M tokens (≤200k tier), change claude-haiku-4-5 to $1.00 input / $5.00 output
per 1M tokens, and verify/update claude-opus-4-7 to $5.00 input / $25.00 output
per 1M tokens; make the edits where those SKUs are defined in the pricing table
so the mapping and values match the provided rates and bump PRICE_TABLE_VERSION
accordingly.

In `@src/signalforge/skills/signalforge/SKILL.md`:
- Line 6: Update SKILL.md to use the correct release version and relax
Anthropic-only wording: change the signalforge-version field from "0.5.0.dev0"
to "0.5.0" (to match src/signalforge/__init__.py and CHANGELOG.md) or add a
brief note why a dev suffix is intentionally used; and modify the drafter
description that currently states “the drafter always calls Anthropic” /
requires ANTHROPIC_API_KEY to reflect the configurable multi-provider
drafting/grading behavior (refer to llm.provider and grade.provider
configuration and supported providers like OpenAI/Gemini) or clearly state that
this particular demo is Anthropic-only if that is the intended constraint.

## [0.4.0] — 2026-05-30

### Added

- **Column-type awareness for the drafter (#159).** `signalforge.manifest.load(project_dir)` now auto-merges column types from a sibling `target/catalog.json` (produced by `dbt docs generate`) into `Column.data_type` on the in-memory `Manifest`. The drafter's prompt — cached manifest summary AND dynamic data-section schema — both already rendered `data_type` when present; populating it from catalog.json closes the dbt-parse-only gap so cooperative LLMs see real warehouse types (`INT64`, `STRING`, `TIMESTAMP`, …) instead of `UNKNOWN`. No CLI flag, no config knob — pure sibling auto-discovery; missing or malformed catalog degrades silently. Case-insensitive column matching (`lower(col_name)`) handles Snowflake's uppercase / BigQuery's preserve / Postgres's lowercase identifier conventions without configuration.
- **OpenAI as a grading + drafting provider (#136).** Set `grade.provider: openai` or `llm.provider: openai` in `signalforge.yml`; requires the `[openai]` install extra and `OPENAI_API_KEY`. Ships four pricing SKUs (`gpt-4o`, `gpt-4o-mini`, `gpt-4.1`, `gpt-4-turbo`); `--estimate` works via tiktoken (no extra API round-trip). Server-side JSON enforcement via `response_format={"type": "json_object"}`. v0.3 ships without prompt caching (no Anthropic-style cache discount); follow-up to evaluate OpenAI prompt caching.
- **Google Gemini as a grading + drafting provider (#137).** Set `grade.provider: gemini` or `llm.provider: gemini` in `signalforge.yml`; requires the `[gemini]` install extra (`pip install signalforge-dbt[gemini]`) and `GOOGLE_API_KEY`. Recommended SKU for both drafter and judge is `gemini-2.5-flash` (also registered: `gemini-2.5-pro`, `gemini-2.0-flash`). Server-side JSON enforcement via `response_mime_type="application/json"`. `--estimate` cost-preview is wired through Gemini's native `client.models.count_tokens` (US-007 of #137; DEC-016) — first-party token counter, one extra API round-trip per estimate, comparable to the Anthropic shape. Ships **without prompt caching** in v0.3 — `LLMProvider` strategy reports `supports_prompt_caching=False` / `supports_token_count=False`, so `call_llm` skips the `cache_control` marker, the `extended-cache-ttl` beta header, and the pre-send `count_tokens` gate; budget per-call cost accordingly under `provider: gemini` (especially for the grader's 4-criterion × ~12-artifact fan-out). Explicit Gemini context caching is tracked as a follow-up.

### Fixed

- **Drafter rejects type-incoherent `custom_sql` business-rule tests at parse time (#159).** `_validate_anchor_contract` gains a sqlglot AST type-coherence check: for each `custom_sql` candidate, parse the SQL via `sqlglot.parse_one(dialect="bigquery")`, walk binary comparison nodes (`<>`, `=`, `<`, `>`, `<=`, `>=`), look each operand's column name up in the model's `Column.data_type` map, and for the two declared type strings test compatibility via sqlglot's `TypeAnnotator.COERCES_TO` table (bidirectional). When both types are known and incompatible (e.g. `INT64` vs `STRING`) a violation is appended; otherwise the check skips silently. Note the mechanism: the schema map is the lookup, NOT a `schema=` kwarg fed to sqlglot's annotator. The check is the parser-side belt-and-braces of a dual-defence with the type-aware prompt (catalog.json merge above); violations join the existing `LLMOutputAnchorContractError.violations` tuple — no new error class. Skip-when-uncertain policy: only bare `Column <op> Column` is flagged; `CAST` / `SAFE_CAST` / `COALESCE` / `IFNULL` / function calls / subqueries / literals / `NULL` / window functions / unknown-type columns / parse errors all skip silently (zero false-positives on legitimate SQL is the contract; the prune engine's `kept-without-evidence` routing remains the safety net). sqlglot promoted from a dev-only transitive to a runtime dep, pinned at `sqlglot>=30,<31` in `[project].dependencies`.
- **`--estimate` grader-side token counts no longer double-count the rubric (#136 US-008 QG).** The pre-US-005 inline Anthropic call passed the rubric in BOTH the `system=` kwarg AND embedded in the cached user-content block, counting it twice per criterion. The first QG fix preserved that for Anthropic byte-identity, which then triple-counted the rubric for OpenAI (system→`system + text` concat → rubric prefix in text). Corrected to match the runtime grader call: rubric in `system=` once, artifact envelope in user content. Real-API `--estimate` figures for the grade-side shift down by ~one rubric per criterion (was: bug → over-report; now: matches what gets billed). Fake-driven byte-identity golden unchanged (canned token counts are call-shape-agnostic).
- **`estimate(...)` engine parameter renamed `anthropic_client` → `client` (#136 US-008 QG).** Post-US-005 the slot was already typed `object | None` and forwarded verbatim to whichever provider strategy is active; the old name implied Anthropic-only and would mislead a future #137 Gemini wiring. CLI in `generate.py` already passed `None` for non-Anthropic providers; the rename surfaces that without behaviour change.

⚠️ Potential issue | 🔴 Critical | ⚡ Quick win

Critical: Duplicate changelog section.

Lines 23-36 contain a duplicate [0.4.0] — 2026-05-30 section with identical content to the [0.5.0] section above (lines 9-22). This appears to be a copy-paste error.

Based on the PR description stating "Cuts v0.5.0 for PyPI," only the v0.5.0 section should exist, or v0.4.0 should have different content if it was a separate release.

🐛 Proposed fix: Remove the duplicate v0.4.0 section
 
 ## [0.5.0] — 2026-05-30
 
 ### Added
 
 - **Column-type awareness for the drafter (`#159`).** `signalforge.manifest.load(project_dir)` now auto-merges column types from a sibling `target/catalog.json` (produced by `dbt docs generate`) into `Column.data_type` on the in-memory `Manifest`. The drafter's prompt — cached manifest summary AND dynamic data-section schema — both already rendered `data_type` when present; populating it from catalog.json closes the dbt-parse-only gap so cooperative LLMs see real warehouse types (`INT64`, `STRING`, `TIMESTAMP`, …) instead of `UNKNOWN`. No CLI flag, no config knob — pure sibling auto-discovery; missing or malformed catalog degrades silently. Case-insensitive column matching (`lower(col_name)`) handles Snowflake's uppercase / BigQuery's preserve / Postgres's lowercase identifier conventions without configuration.
 - **OpenAI as a grading + drafting provider (`#136`).** Set `grade.provider: openai` or `llm.provider: openai` in `signalforge.yml`; requires the `[openai]` install extra and `OPENAI_API_KEY`. Ships four pricing SKUs (`gpt-4o`, `gpt-4o-mini`, `gpt-4.1`, `gpt-4-turbo`); `--estimate` works via tiktoken (no extra API round-trip). Server-side JSON enforcement via `response_format={"type": "json_object"}`. v0.3 ships without prompt caching (no Anthropic-style cache discount); follow-up to evaluate OpenAI prompt caching.
 - **Google Gemini as a grading + drafting provider (`#137`).** Set `grade.provider: gemini` or `llm.provider: gemini` in `signalforge.yml`; requires the `[gemini]` install extra (`pip install signalforge-dbt[gemini]`) and `GOOGLE_API_KEY`. Recommended SKU for both drafter and judge is `gemini-2.5-flash` (also registered: `gemini-2.5-pro`, `gemini-2.0-flash`). Server-side JSON enforcement via `response_mime_type="application/json"`. `--estimate` cost-preview is wired through Gemini's native `client.models.count_tokens` (US-007 of `#137`; DEC-016) — first-party token counter, one extra API round-trip per estimate, comparable to the Anthropic shape. Ships **without prompt caching** in v0.3 — `LLMProvider` strategy reports `supports_prompt_caching=False` / `supports_token_count=False`, so `call_llm` skips the `cache_control` marker, the `extended-cache-ttl` beta header, and the pre-send `count_tokens` gate; budget per-call cost accordingly under `provider: gemini` (especially for the grader's 4-criterion × ~12-artifact fan-out). Explicit Gemini context caching is tracked as a follow-up.
 
 ### Fixed
 
 - **Drafter rejects type-incoherent `custom_sql` business-rule tests at parse time (`#159`).** `_validate_anchor_contract` gains a sqlglot AST type-coherence check: for each `custom_sql` candidate, parse the SQL via `sqlglot.parse_one(dialect="bigquery")`, walk binary comparison nodes (`<>`, `=`, `<`, `>`, `<=`, `>=`), look each operand's column name up in the model's `Column.data_type` map, and for the two declared type strings test compatibility via sqlglot's `TypeAnnotator.COERCES_TO` table (bidirectional). When both types are known and incompatible (e.g. `INT64` vs `STRING`) a violation is appended; otherwise the check skips silently. Note the mechanism: the schema map is the lookup, NOT a `schema=` kwarg fed to sqlglot's annotator. The check is the parser-side belt-and-braces of a dual-defence with the type-aware prompt (catalog.json merge above); violations join the existing `LLMOutputAnchorContractError.violations` tuple — no new error class. Skip-when-uncertain policy: only bare `Column <op> Column` is flagged; `CAST` / `SAFE_CAST` / `COALESCE` / `IFNULL` / function calls / subqueries / literals / `NULL` / window functions / unknown-type columns / parse errors all skip silently (zero false-positives on legitimate SQL is the contract; the prune engine's `kept-without-evidence` routing remains the safety net). sqlglot promoted from a dev-only transitive to a runtime dep, pinned at `sqlglot>=30,<31` in `[project].dependencies`.
 - **`--estimate` grader-side token counts no longer double-count the rubric (`#136` US-008 QG).** The pre-US-005 inline Anthropic call passed the rubric in BOTH the `system=` kwarg AND embedded in the cached user-content block, counting it twice per criterion. The first QG fix preserved that for Anthropic byte-identity, which then triple-counted the rubric for OpenAI (system→`system + text` concat → rubric prefix in text). Corrected to match the runtime grader call: rubric in `system=` once, artifact envelope in user content. Real-API `--estimate` figures for the grade-side shift down by ~one rubric per criterion (was: bug → over-report; now: matches what gets billed). Fake-driven byte-identity golden unchanged (canned token counts are call-shape-agnostic).
 - **`estimate(...)` engine parameter renamed `anthropic_client` → `client` (`#136` US-008 QG).** Post-US-005 the slot was already typed `object | None` and forwarded verbatim to whichever provider strategy is active; the old name implied Anthropic-only and would mislead a future `#137` Gemini wiring. CLI in `generate.py` already passed `None` for non-Anthropic providers; the rename surfaces that without behaviour change.

⚠️ Potential issue | 🟡 Minor | ⚡ Quick win

Speculative Gemini recommendation marked as pending validation.

The table presents a 4096 floor for Gemini with an explicit caveat that it's "pending Gemini-drafter live validation" (line 766). Including this alongside validated floors for Anthropic and OpenAI may lead operators to treat it as a verified recommendation when the evidence is not yet available.

Consider either:

  1. Moving the Gemini row to a separate "Provisional (pending validation)" section
  2. Deferring the Gemini row until live validation completes
  3. Adding a prominent table header note that Gemini figures are provisional

⚠️ Potential issue | 🟠 Major | ⚡ Quick win

Don't reject mixed-provider --estimate runs.

The real pipeline now supports independent draft.provider and grade.provider, but this guard turns any mixed setup into a CLI error even when only one side needs an SDK client. With the current implementations, an openai/gemini stage can estimate locally, so configs like draft=openai, grade=anthropic should still be estimable by constructing an Anthropic client if either stage needs it.
