Any vendor whose SDK uses a different call shape gets the same shim adaptation rather than a special-case branch in `call_llm`. +2. **`response_format={"type":"json_object"}` belt-and-braces with the tolerant JSON parser (DEC-006 of #136).** `OpenAIProvider.build_create_kwargs` attaches the JSON-mode flag at every call. The grade + draft system prompts already contain "json" (case-insensitive), satisfying OpenAI's prompt-requirement check. The tolerant `extract_json_payload` parser (issue #144) remains the fallback if a future model strips the flag; server-side enforcement eliminates the prose-preamble drift class entirely for the providers that support it. **A future vendor with an equivalent JSON-mode (e.g. Gemini's `response_mime_type="application/json"`) MUST set it for the same reason — don't lean on the parser alone when the API exposes a server-side gate.** +3. **`tiktoken` model-id fallback for `--estimate` (DEC-012 of #136).** `_count_openai_tokens(model, text)` calls `tiktoken.encoding_for_model(model)` inside a try/except, falling back to `tiktoken.get_encoding("cl100k_base")` on `KeyError` for unknown ids (newer model SKUs released after the installed `tiktoken` ship out of the registry). **Don't raise on unknown id** — `--estimate` is a calibration signal, not a billing guarantee (mirrors the `EXPLAIN`-based planner-estimate caveat in `warehouse-adapters.md`). + +### `estimate_input_tokens(*, system=...)` — separate the system envelope to preserve real-API byte-identity (#136 US-005 / DEC-013, refined by US-008 QG) + +The `--estimate` path generalised in US-005 via `LLMProvider.estimate_input_tokens(model, text, *, system="", client=None)`.

The pre-refactor inline call did the same — and Anthropic's server-side tokenizer applies its own system-envelope tokens to that block. Dropping the kwarg (concatenating system into the user-content text) silently under-reports real-API counts by the system-envelope size, while a fake-driven byte-identity snapshot still passes because the fake returns canned `input_tokens` regardless of kwargs. **Lesson — fake-driven byte-identity tests pin rendered-output identity, NOT real-API call shape.** If a refactor changes the SDK call shape, the snapshot won't catch it; a real-API `@pytest.mark.anthropic` test against `--estimate` (or an explicit kwargs-shape assertion on the fake) is the only way. This is the same "snapshot/sqlglot tier vs live tier" gap documented in `warehouse-adapters.md` for the Snowflake compiler. +- **OpenAIProvider** concatenates `system + text` before `tiktoken` — there's no system-envelope distinction at the BPE level, so every token contributes to the same total. Matches what OpenAI's chat-completion endpoint bills. +- **Grade-side estimate (`_count_grade_criterion_tokens`) deliberately double-counts the rubric.** The pre-refactor shape passed `system=system_and_rubric` AND embedded `system_and_rubric` inside the cached user-content block, so the rubric was counted twice. This was already the behaviour; preserving byte-identity required reproducing it. **Don't "fix" this double-count in a future tidy-pass — it's the pre-refactor shape, and a quiet repair would silently shift estimate figures by ~the rubric size.** A real future cleanup would need a tied snapshot regeneration + operator-visible "estimate calibration changed" CHANGELOG entry. + +A new provider added under #137+ MUST implement `estimate_input_tokens` (it's `@abstractmethod`; missing impls fail at instantiation time).

The pattern generalises #136's adapter shape to any vendor whose SDK exposes a differently-named namespace; the orchestrator stays vendor-neutral by construction. +2. **Server-side JSON via `response_mime_type="application/json"` (DEC-018 of #137).** `GeminiProvider.build_create_kwargs` attaches it inside the `config=...` dict that `models.generate_content` accepts. Mirrors OpenAI's `response_format={"type":"json_object"}` exactly per the precedent above — server-side enforcement eliminates the prose-preamble drift class; the tolerant `extract_json_payload` parser remains the fallback. +3. **Non-clean finish_reason → typed `LLMResponseFormatError` (DEC-005 of #137, generalised provider-neutral by DEC-001/DEC-005 of #155).** Every provider exposes a "completion is unusable" signal via its native finish-reason field: Anthropic `stop_reason ∈ {max_tokens, refusal, tool_use, ...}`, OpenAI `choices[0].finish_reason ∈ {length, content_filter, tool_calls, ...}`, Gemini `candidates[0].finish_reason.name ∈ {MAX_TOKENS, SAFETY, RECITATION, OTHER, ...}`. The rule is enforced uniformly at the orchestrator boundary via the `LLMProvider.is_clean_completion(response) -> bool` ABC method (DEC-005 of #155) called by `call_llm` AFTER `messages.create` returns and BEFORE `extract_text_blocks` is invoked; when it returns `False`, `call_llm` raises `LLMResponseFormatError(strategy.unclean_finish_reason_message(response))`. Each provider declares its `_CLEAN_STOP_REASONS: frozenset[str]` (Anthropic `{end_turn, stop_sequence}`, OpenAI `{stop}`, Gemini `{STOP}`) — **anything else is unclean, regardless of whether text is also present.** This load-bearing post-#155 generalisation closes a Finding-1-shaped gap: a `MAX_TOKENS` truncation that emits *partial* text would otherwise slip through any "no text at all" gate and the downstream parser would degrade with `GradeOutputError(json_parse)` masking the actionable typed cause. `call_llm` propagates the raise as an `LLMError`; `grade_artifacts` wraps to `GradeLLMError` → conservative degrade per `grade-layer.md` (the `reasoning="call failed: GradeLLMError"` contract pin lives in `tests/grade/test_gemini_neutrality.py`, and the post-#155 per-provider unclean-path pins live in `tests/llm/test_{anthropic,openai,gemini}_provider_via_fake.py` + `tests/llm/test_client.py`). **The typed degrade is the contract — a future vendor with an analogous safety / truncation surface MUST route through the same `is_clean_completion` → `LLMResponseFormatError` → typed-degrade path rather than returning empty text or a sentinel.** `tool_use` is deliberately UNCLEAN for Anthropic (DEC-006 of #155) since the codebase doesn't use tools today; if/when tool-use intentionally lands the clean set expands deliberately. Don't add a per-provider error class — the existing `LLMError` hierarchy already covers it. Don't push the check into individual `extract_text_blocks` implementations — that splits responsibility across providers (one might forget; the next vendor lands with no enforcement); the ABC method centralises the rule. Per-provider `unclean_finish_reason_message(response) -> str` (DEC-007 of #155) keeps operator-facing diagnostics vendor-accurate (Anthropic says "stop_reason"; OpenAI/Gemini say "finish_reason"). +4. **Native `models.count_tokens` for `estimate_input_tokens` (DEC-016 of #137).** Distinct from OpenAI's local `tiktoken` path: Gemini has a first-party server-side count API, so `GeminiProvider.estimate_input_tokens(model, text, *, system="", client=None)` calls `client.models.count_tokens(model=model, contents=[system + text])` and reads `response.total_tokens`. One extra API round-trip per estimate (comparable in shape to the Anthropic path). `system + text` is concatenated into a single `contents` entry — Gemini's count endpoint doesn't distinguish a system envelope from regular tokens (unlike Anthropic), so every token contributes to the same total and the figure matches what `generate_content` will bill at runtime. **Don't reach for `tiktoken` for a vendor that ships its own count API.** Verify the response field name against the installed SDK version — `total_tokens` is correct for `google-genai>=0.5,<1`; a future SDK rev may rename it. + +### Namespace-package SDKs (#137 generalisation) + +`google-genai` ships as a namespace-package — `from google import genai` rather than `import genai`.

The new private helper `_check_custom_sql_type_coherence(sql, model_columns_by_type, dialect_name) -> tuple[str, ...]` parses the SQL via `sqlglot.parse_one(dialect=dialect_name)`, annotates types via `sqlglot.optimizer.annotate_types(schema=...)`, walks binary comparison nodes (`<>`, `=`, `<`, `>`, `<=`, `>=`), and flags violations where two known-type column references compare incompatible types.

Every other shape skips silently. Zero false-positives on legitimate SQL is the contract; missing some real bugs is the acceptable tradeoff (the prune engine's `kept-without-evidence` routing remains the safety net for cases the parser can't catch). +2. **Jinja substitution before parse.** LLM-emitted `custom_sql` almost always references `{{ this }}`; raw `sqlglot.parse_one` would raise `ParseError` and the entire defence would skip-silently for every candidate. The helper swaps `{{ ... }}` → a placeholder identifier (`__sf_jinja__`) via a regex pass BEFORE `parse_one`, keeping the WHERE-clause comparison nodes intact (which is all the walker consumes). The placeholder is unused downstream; the prune compiler's own `resolve_template_refs` (`manifest.py`) handles real Jinja resolution at compile time. +3. **`sqlglot.errors.ParseError` skips silently.** Invalid SQL is caught downstream by the warehouse adapter (`QuerySyntaxError` → `kept-without-evidence`).

Reads `/signalforge.yml`, overlays the `grade:` block deltas, writes back. Non-destructive: unset knobs left alone. Raises `FileNotFoundError` if the fixture's `signalforge.yml` is missing. This is the seam #155 US-005/US-006/US-007 (the three e2e provider variants) all flow through. + +Two load-bearing rules: (1) **per-test overlay, not a `GradeConfig` default bump.** Lowering `GradeConfig.max_output_tokens` default would over-budget Anthropic/OpenAI calls; the per-test overlay scopes the Gemini-specific 2048 floor to the test that needs it (DEC-009 of #155). (2) **Drafter stays Anthropic Sonnet across all three e2e providers per DEC-011** — fixture stability requires only the grader varies. Tests that overlay `grade_provider` MUST still gate on `ANTHROPIC_API_KEY` (drafter) AND the provider-specific key (grader); a 3-env-var skip gate is insufficient when the drafter remains Anthropic — five is the contract (drafter API key + grader API key + their respective `SF_RUN_*` opt-ins + `GOOGLE_CLOUD_PROJECT` for the BigQuery leg). #155 QG Pass 4 caught the openai-smoke 3-vs-5 drift exactly because the docstring contract said "three" while the BQ smoke + Gemini sibling already used the five-var pattern. + +The same belt-and-suspenders gating still applies: marker + runtime `_skip_reason()` + `tmp_path` isolation. The overlay is applied AFTER `copy_fixture_to_tmp` so the committed fixture is never modified. + +### Parallel-safe e2e via per-test isolation (issue #157) + +The live e2e suite is **parallel-safe at the pytest-node level** under `pytest-xdist`. The granularity is deliberate: parallelism is *across* tests, NOT *inside* a test — the grade engine stays sequential per `grade-layer.md` § "One LLM call per (artifact × criterion); sequential (DEC-004, DEC-027)". A single test still issues its grade calls one at a time; what `-n 3` does is run three *tests* in parallel pytest-xdist workers. + +**The contract — every e2e test is self-isolating; no shared mutable state.** Three primitives in `tests/cli/_e2e_helpers.py` make this work, and every e2e test reaches for them in the same order: + +1. **`copy_fixture_to_tmp(fixture_dir, tmp_path)`** — every test gets a private fixture copy under `tmp_path`. The committed fixtures (`tests/fixtures/dbt_project_austin`, `tests/fixtures/snowflake/...`) are read-only. +2. **`apply_provider_override(project_dir, *, grade_provider=None, grade_model=None, grade_max_output_tokens=None)`** — per-test config overlay on the copy's `signalforge.yml` (NOT on the committed file). Per-test scope per #155 US-004 / DEC-012. +3. **`inject_model_business_rules(project_dir, *, model_unique_id, column_rules=..., model_rules=...)`** — per-test mutations of `meta.signalforge.business_rules` on the **copied** `manifest.json`, leaving the committed seed untouched (issue #116 e2e shape). + +All writes (audit JSONLs, sidecars, `signalforge.yml` overlays, manifest mutations) land under `tmp_path`. **No env mutation between tests.** The helpers route per-test config through file edits on the temp copy, never through `os.environ` — so a parallel test cannot leak state into a sibling xdist worker. + +**The invocation.** `uv run pytest -m e2e -n 3 --no-cov` is the maintainer-recommended path (documented in `CONTRIBUTING.md` § "Live e2e suite (pre-release only)"). `pytest-xdist` is a dev-group dep (added by #157 US-004) — `uv sync --dev` pulls it automatically; default `addopts` stays sequential, so parallelism is **opt-in only**, never CI-default. `-n 3` is a deliberate choice, NOT `-n auto`: it bounds the Anthropic-singleton fan-out. + +**The Anthropic 50-RPM caveat (load-bearing).** The drafter is Anthropic on every variant, and the `[anthropic]` BQ-smoke parametrize + the business-rules test ALSO use Anthropic as the grader. With `-n 3`, three parallel tests can collectively issue ~50 calls in a tight window and trigger the `WARNING: rate limit` retry path (`llm-drafter.md` § "Module-level `_sleep` / `_rand_uniform` aliases" — retries are bounded by `DraftConfig.max_retries_429` / `GradeConfig.max_retries_429`). The 2026-05-29 baseline measured against the Austin bikeshare fixture observed **zero rate-limit retries** at `-n 3`; richer fixtures or a tighter Anthropic tier may need `-n 2` or `-n 1`.

That's the most consequential row in +the table for anyone budgeting a real workload, so it earns its own +section. + +### What prompt caching is (business framing) + +Every LLM call bills you for **every input token, every time** — +even if 90% of the prompt is boilerplate you sent five seconds ago +on the previous call. Prompt caching is the provider's offer: tell +me which chunk of the prompt is the *stable prefix*, I'll fingerprint +it on my side, and on subsequent calls within a TTL window I'll +charge you a steep discount on those tokens instead of the full +input rate. + +Anthropic's published rates for `claude-sonnet-4-6` (SignalForge's +default; the figures live in +[`signalforge/llm/pricing.py`](https://github.com/wjduenow/SignalForge/blob/dev/src/signalforge/llm/pricing.py)): + +| Token class | Rate (USD / Mtok) | vs. full input | +|---|---|---| +| Full input | $3.00 | baseline | +| Cache **write** (first call seeds the cache) | $3.75 | 25% premium | +| Cache **read** (later calls within TTL hit the cache) | $0.30 | 90% discount | + +You pay a small premium once to seed the cache, then 10¢ on the +dollar for every read. Break-even is roughly one follow-up call; +from the 2nd call onward you're saving money. + +### Where this matters in SignalForge + +- **Drafter** — one LLM call per `signalforge generate` invocation. + The cached prefix is the system prompt + the manifest summary. + Inside a single `--select` batch of 20 models, calls 2–20 hit the + cache. Modest but real savings. +- **Grader** — ~48 LLM calls on a typical model (~12 artifacts × 4 + rubric criteria; see + [`grade-ops.md` § One LLM call per artifact × criterion](grade-ops.md)). + The cached prefix is the rubric criterion list. Once per run the + rubric is "written" to the cache; the other ~47 calls "read" it + at 90% off. This is where prompt caching pays for itself + loudest. + +### Why OpenAI isn't supported + +OpenAI's Chat Completions API has an automatic prompt-caching +feature, but it's deliberately opaque: + +1. **No marker, no control surface.** Anthropic exposes an inline + `cache_control` marker on the block you want cached; OpenAI's + backend pattern-matches recent prompts and applies discounts + silently. SignalForge cannot *steer* the cache toward the + system + cached-block prefix that matters. +2. **No public per-MTok rate.** Anthropic publishes a cache-write + premium and a cache-read discount, so + `signalforge.llm.pricing.PRICES` can model both. OpenAI's + discount tier isn't published in the same shape, so + `--estimate` cannot project caching savings honestly. +3. **No `cache_creation_input_tokens` / `cache_read_input_tokens` + in the usage response.** Anthropic returns both fields per call, + which feeds the dual-zero cache-anomaly WARNING and the audit + JSONL's reproducibility hashes. OpenAI's usage shape carries no + equivalent — even *measuring* whether a cache hit fired after + the fact is awkward. + +So `OpenAIProvider.supports_prompt_caching = False` is the honest +posture: we can't steer the cache, we can't price the cache, and we +can't audit the cache. Whatever automatic discount OpenAI applies +on their side, the operator gets — SignalForge just doesn't model +it. `cache_ttl` in `signalforge.yml` is accepted and silently +ignored for OpenAI. + +### Why Gemini isn't supported (yet) + +Gemini ships **context caching** — a real, usable feature — but its +shape is fundamentally different from Anthropic's inline marker: + +1. **Separate API call.** You call `CachedContent.create(...)` + before the generation call to upload the chunk to a named cache + resource, get back a handle, and reference the handle on every + subsequent `generate_content(...)`. Anthropic's `cache_control` + marker is a single field inside the existing + `messages.create(...)` call. +2. **Separate pricing dimension.** Gemini bills cache **storage** + per hour while the cached resource lives, plus a per-token + discount on cached reads. The cost model is "rent the cache + slot, get cheaper reads" — fundamentally different from + Anthropic's "pay a write premium once, get cheap reads." +3. **Minimum payload + lifecycle.** Gemini's cached content has a + minimum size and an explicit TTL the operator manages; an + abandoned cache keeps billing storage until it expires. + +Wiring Gemini context caching correctly into SignalForge means a +separate "warm the cache" code path, a TTL strategy, an +`LLMResult.usage` shape that includes Gemini's distinct cache +fields, and a `pricing.py` schema extension carrying the storage +rate alongside the existing per-MTok rates. None of that was in +scope for issue +[#137](https://github.com/wjduenow/SignalForge/issues/137) (which +landed Gemini as a third provider proving the seam holds). It's a +tracked follow-up — `GeminiProvider.supports_prompt_caching = False` +today; `cache_ttl` is accepted and silently ignored. + +The asymmetry isn't "Gemini is worse than Anthropic"; it's +"Anthropic's caching maps onto the existing seam in one config line +(`cache_ttl: 5m | 1h`), and Gemini's caching needs a code path we +haven't built yet." + +### The practical bottom line + +On the grader (the high-call-count surface where caching matters +most), the math typically nets out: + +- **Anthropic** — 1 cache-write rubric + ~47 cache-read rubrics at + 10¢-on-the-dollar input tokens. +- **Gemini `gemini-2.5-flash`** — 48 full-input rubrics, but each + input token costs ~10× less than `claude-sonnet-4-6`. +- **OpenAI `gpt-4o-mini`** — 48 full-input rubrics, input tokens + ~20× cheaper than `claude-sonnet-4-6`. + +Cheaper-per-token providers usually still come out ahead on +absolute dollars even without caching — they're just leaving +optimization on the table that Anthropic doesn't. If Gemini +context caching lands as a follow-up, Gemini becomes substantially +cheaper still. + +## Choosing a provider + +Three dimensions to weigh: + +1. **Per-token cost.** At PR-prep prices + ([`signalforge/llm/pricing.py`](https://github.com/wjduenow/SignalForge/blob/dev/src/signalforge/llm/pricing.py)), + the cheapest grader SKU is `gpt-4o-mini` + ($0.15 / $0.60 per Mtok in/out), followed by `gemini-2.0-flash` + ($0.10 / $0.40 per Mtok in/out — even cheaper, but a budget + model). `claude-sonnet-4-6` at $3 / $15 per Mtok costs ~20× more + per token, partly offset by prompt caching on the cached + prefix. +2. **Caching impact.** Anthropic's prompt-cache discount (5m or 1h + TTL) is meaningful for the drafter's cached manifest block AND + for the grader's cached rubric block when grading multiple + artifacts per criterion. Neither OpenAI nor Gemini exposes a + comparable discount today — every call pays the full input rate. +3. **Quality variance.** Gemini's verbose reasoning needs the 4096 + `max_output_tokens` floor to avoid mid-string truncation + (issue #155); OpenAI's tighter `response_format` JSON mode is the + simplest route to a clean parse but has shown lower judge + evidence quality on some fixtures. Anthropic's judge model + carries the longest production exposure (the v0.1–v0.2 e2e + smokes all ran Anthropic). + +**Practical patterns:** + +- **Single-provider Anthropic** (the default). Simplest setup, best + caching, highest unit cost. Right answer when you don't want to + manage two API keys. +- **Anthropic drafter + Gemini grader.** Drafter benefits from + caching across `--select` siblings; grader fan-out runs at the + cheaper per-token rate. The shipped end-to-end smoke fixture + exercises this configuration (issue + [#155](https://github.com/wjduenow/SignalForge/issues/155)). +- **OpenAI both stages.** Right answer when you're already + standardised on OpenAI billing and don't want to manage an + Anthropic key. `gpt-4o` + `gpt-4o-mini` are inexpensive and + reliable; no caching discount but no truncation risk either. +- **Gemini both stages.** Cheapest per-token; needs the 4096 + `max_output_tokens` floor and a tolerance for occasional + `aggregate_complete=False` reports when the safety filter or + truncation fires. + +## Cost & token accounting + +`signalforge generate --estimate` projects per-stage cost before the +billable run. Each provider supplies its own token counter via +`LLMProvider.estimate_input_tokens(model, text, *, system="", client=None)`: + +- **Anthropic** — live `messages.count_tokens`; `system` is passed + as its own kwarg so the system envelope is counted server-side. +- **OpenAI** — local `tiktoken` (no API round-trip); + `tiktoken.encoding_for_model(model)` with `cl100k_base` fallback. +- **Gemini** — native `models.count_tokens`; `system + text` + concatenated into one `contents` entry (Gemini doesn't + distinguish a system envelope). + +`signalforge.llm.cost.rollup_audit_dir(project_dir) -> CostReport` +walks `.signalforge/llm_responses.jsonl` and `.signalforge/grade.jsonl` +after a run and computes per-provider per-model USD against the +frozen `signalforge.llm.pricing.PRICES` table. The CLI wrapper is +`scripts/measure_e2e_cost.py`. See +[`docs/cost-estimate-ops.md`](cost-estimate-ops.md) for the full +contract, including the `>` degrade when a +supplementary surface fails. + +## Reliability & error handling + +### Retry taxonomy (drafter + grader) + +Every provider classifies SDK exceptions through +`LLMProvider.classify_exception(exc) -> ExceptionCategory` (one of +`AUTH`, `RATE_LIMIT`, `SERVER_ERROR`, `CONNECTION`, `NO_RETRY`). +`call_llm` runs the same generic retry loop regardless of provider: +429 × 3, 5xx × 1, connection × 1, 401/403 no-retry-but-hint, 4xx +no-retry. Each retry emits one `WARNING` with `attempt` / `delay` +/ `error_class` / `model`. Per-class budgets are configurable per +stage (`DraftConfig.max_retries_429` / +`GradeConfig.max_retries_429`). + +### Conservative degrade (grader) + +A grade pair that exhausts retries, hits a non-clean `finish_reason`, +or trips its per-pair budget routes through the conservative +`score=None, passed=False, reasoning=""` degrade — +never aborts the whole run. The aggregate +`pass_rate` / `mean_score` are computed over the **scored** subset +only; `aggregate_complete: bool` flags partial reports. The whole +run aborts **only** if the audit JSONL writer itself fails. See +[`docs/grade-ops.md` § Conservative score-and-degrade taxonomy](grade-ops.md). + +### Fail-loud (drafter) + +The drafter has no equivalent degrade path — a single failing LLM +call is a hard failure. The retry loop runs; on exhaustion, the +CLI exits at tier 3 (Anthropic / external dependency failure) with +a typed error message and no traceback. See +[`docs/draft-ops.md` § Retry taxonomy](draft-ops.md#retry-taxonomy). + +### Prompt-injection envelopes + +User-controlled content (model SQL for the drafter, drafted artifact +text for the grader) is wrapped in named fences: + +- Drafter: `...` and + `...` (the latter for + `meta.signalforge.business_rules`, see + [`docs/draft-ops.md` § Custom business-rule tests](draft-ops.md#custom-business-rule-tests-custom_sql)). +- Grader: `...`. + +A payload containing the literal closing tag raises +`PromptEnvelopeBreachError` / `GradePromptEnvelopeBreachError` +BEFORE the LLM call is issued — a fail-loud pre-flight scan over +every payload at orchestrator entry. The defence is a boring +substring match; no whitespace / case normalisation. + +## Audit & reproducibility + +Every LLM call lands a structured record on disk. Both writers are +fail-closed: the call only "succeeds" once the audit byte hits disk +via `os.write` + `os.fsync`. An audit-write failure aborts the run +with a typed `LLMResponseAuditWriteError` / `GradeAuditWriteError` +(CLI tier 3). + +| File | Layer | Shape | +|---|---|---| +| `.signalforge/audit.jsonl` | safety | One record per `build_llm_request` — what data went to the LLM (columns sent, redactions applied, sampling mode). | +| `.signalforge/llm_responses.jsonl` | drafter | One record per drafter call — `sent_sql_hash`, `parsed_schema_hash`, `response_text_hash`, `prompt_version`, cache token usage, model id, `signalforge_version`. | +| `.signalforge/grade.jsonl` | grader | One record per `(artifact × criterion)` pair — `rubric_hash`, `prompt_version_template`, `criterion_prompt_hash`, `response_text_hash`, scored / degraded state. | +| `.signalforge/grade.json` | grader | End-of-run sidecar; `GradingReport` with per-criterion scores + the `aggregate_complete` flag. | +| `.signalforge/diff.json` | diff | Sidecar with the kept/dropped/flagged tier table + unified diff + reproducibility hashes. | + +The reproducibility hash fields make per-run output bytewise +verifiable: same input → same hashes → same decisions.

The gate runs inside the +canonical `VALIDATE_CMD` +(`uv run pytest`), so a CLI change that drifts the surface from the skill +fails validation until `SKILL.md` is updated in the same change. + +This is the gate-over-prompt enforcement described in +[`.claude/rules/skill-parity.md`](https://github.com/wjduenow/SignalForge/blob/dev/.claude/rules/skill-parity.md) +— the contributor never has to remember to update SKILL.md; the test +suite makes drift impossible.

The provider strategy owns: build create-kwargs, build count-tokens-kwargs, extract text blocks, extract usage, classify exception→category, and capability flags. The orchestrator never touches an Anthropic-shaped dict. +- **DEC-002 — Neutral value objects.** Introduce `UsageMetrics(input_tokens, output_tokens, cache_creation_input_tokens=0, cache_read_input_tokens=0)` and an `ExceptionCategory` enum (`AUTH`, `RATE_LIMIT`, `SERVER_ERROR`, `CONNECTION`, `NO_RETRY`). `extract_usage`→`UsageMetrics`; `classify_exception`→`ExceptionCategory`. Orchestrator dispatches on the enum, not on SDK exception classes. +- **DEC-003 — `LLMProvider` ABC + registry.** New `llm/providers.py`: `LLMProvider(abc.ABC)` (abstract `make_client`, `build_create_kwargs`, `build_count_tokens_kwargs`, `extract_text_blocks`, `extract_usage`, `classify_exception`; class-attr/property `name`, `supports_prompt_caching`, `supports_token_count`) + a process-level registry (`register_provider(provider)` / `provider_for(name) -> LLMProvider`; unknown name → typed `LLMError` subclass listing available keys). Mirrors `WarehouseAdapter.from_profile` dispatch, adapted to a name registry so new providers register rather than editing a factory `if`-ladder. +- **DEC-004 — Module layout (SD-3).** Rename `_client.py`→`_anthropic_client.py` (keeps `AnthropicClientProtocol` public per #44, plus `_AnthropicExceptionClasses`/`_make_anthropic_client`/`_load_anthropic_exception_classes`). `llm/providers.py` holds the ABC + value objects + registry. Future vendors add `_openai_client.py` siblings + a provider class. No new subpackage. +- **DEC-005 — `call_anthropic`→`call_llm`, drop old name (SD-4).** `call_llm` added to `__all__`; `call_anthropic` removed. Migrate both call sites + every test import + the `test_public_api.py`/`test_schema.py` documented-surface lists. +- **DEC-006 — Real-client construction pushed into `call_llm` (RF-1).** When `client is None`, `call_llm` resolves the strategy via the registry and calls `strategy.make_client()`. The CLI generate path stops calling `_make_anthropic_client`; it passes `provider=config.provider`. The 7 CLI monkeypatch tests switch to patching `AnthropicProvider.make_client` (or the registry) / injecting a fake client. +- **DEC-007 — `provider` config field on BOTH configs, registry-validated `str` (SD-1).** `DraftConfig.provider: str = "anthropic"` and `GradeConfig.provider: str = "anthropic"`, each with a validator asserting registry membership (fail-loud on unknown, listing available providers — mirrors the `trusted_models` validate-at-entry fail-loud). **Deliberate deviation from the `Literal`+`extra="forbid"` convention** (`safety-layer.md` DEC-015): a provider registry is a plugin point designed to grow, so #136/#137 register a provider instead of editing a `Literal` in two places, and a test can register a fake provider for AC #3. `call_llm` gains `provider: str = "anthropic"`. Other `extra="forbid"` config fields are unchanged. +- **DEC-008 — Capability degrade semantics.** `supports_prompt_caching=False` ⇒ no `cache_control` marker, no `extended-cache-ttl` beta header, report 0 cache tokens, skip the dual-zero anomaly WARNING. `supports_token_count=False` ⇒ skip the pre-send count gate entirely (no `LLMCacheTooLargeError` raised pre-send; documented deferral — a provider without token-counting can't enforce the 8000 cap up front). Anthropic sets both `True`, so its control flow + emitted bytes are unchanged. +- **DEC-009 — Keep `cache_ttl` config + `cache_*_input_tokens` audit fields as-is.** `cache_ttl: Literal["5m","1h"]` stays on both configs (Anthropic-specific; ignored when `supports_prompt_caching=False`). `LLMResponseEvent`/`GradeEvent` keep `cache_creation_input_tokens`/`cache_read_input_tokens` (default 0).

No new scan in #135; a future provider's SDK-construction confinement (e.g. `openai.OpenAI()`) is that provider ticket's job. +- **DEC-011 — No-cache fake provider proves AC #2 + #3.** A test-only provider (`supports_prompt_caching=False`, `supports_token_count=False`) registered in the registry, selected via `grade.provider`, driven through `grade_artifacts` → assert: audit JSONL + sidecar round-trip, `cache_*_input_tokens==0`, drift detector + reproducibility blake2b hashes intact, no dual-zero WARNING. The fake IS the "shim + exception map + enum value" wiring, so it doubles as the AC #2 proof. +- **DEC-012 — Public client-protocol typing.** `AnthropicClientProtocol` stays public + Anthropic-specific (back-compat, #44). `call_llm`'s `client` param is typed `object | None` and handed to the strategy; `draft_schema`/`grade_artifacts` keep `client: AnthropicClientProtocol | None` (Anthropic is the default injection surface) — documented that non-Anthropic providers build their own client and ignore the kwarg. + +## Story breakdown (Phase 4) + +Ordering: foundation types → Anthropic strategy + rename → generic orchestrator → config/CLI wiring → neutrality proof → docs.

Extend Scan 3 in `tests/test_audit_completeness.py` to also exclude `_openai_client.py` for `openai.OpenAI(...)` constructions. Mirrors Anthropic precedent exactly. **Resolution:** add the new AST scan + add `openai` to the per-SDK exclusion lists. | +| **`.messages` adapter shape** | concern | OpenAI SDK exposes `client.chat.completions.create(...)`, NOT `client.messages.create(...)`. The orchestrator hard-calls `llm_client.messages.create(**kwargs)`. **Resolution:** `OpenAIProvider.make_client()` returns a thin adapter object whose `.messages.create(**kwargs)` delegates to the underlying `openai.OpenAI().chat.completions.create(**kwargs)`. `messages.count_tokens` is never called (`supports_token_count=False`); the adapter raises `NotImplementedError` on that path defensively. | +| **`build_count_tokens_kwargs` ABC contract** | pass | A provider with `supports_token_count=False` never sees the method called by the orchestrator. Precedent: `FakeNoCacheProvider.build_count_tokens_kwargs` raises `NotImplementedError`. Match that. | +| **Anthropic byte-identity** | concern | The estimate refactor (SD-3) threads a provider strategy through `_count_draft_tokens` + the grader-side equivalent. **Anthropic estimate output must stay byte-identical.** Resolution: extract the SDK-call into a per-strategy `count_input_tokens(client, ...) -> int` method; Anthropic impl is the existing `client.messages.count_tokens(...)` call verbatim. Pin a snapshot test on Anthropic estimate stdout before refactor + verify after. | +| **`tiktoken` dependency** | concern | Adding a local-tokeniser dependency for OpenAI estimate. `tiktoken` is OpenAI-published, MIT, no native build (wheels for cpython 3.11–3.13). **Resolution:** add to the `[openai]` optional extra, lazy-import inside `_openai_client.py`. `OpenAIProvider.count_input_tokens` uses tiktoken's `encoding_for_model` with a graceful fallback to `cl100k_base` for unknown model ids. | +| **Pricing table churn** | pass | `_PRICES_MUTABLE` gains OpenAI SKUs (at minimum `gpt-4o`); `PRICE_TABLE_VERSION` bumps. Additive change. Cache fields set to `0.0` (OpenAI has no equivalent cache discount). | +| **Drafter provider symmetry** | concern | #135 gave BOTH `grade.provider` and `draft.provider` a `str` field. Once `OpenAIProvider` is registered, both stages naturally accept `provider: openai`. **Decision needed (refinement):** scope #136 to "grade only" with `draft.provider: openai` documented as untested-but-permitted, OR explicitly cover both stages. The work is identical; the doc message differs. | +| **GradeEvent / drift detector** | pass | `GradeEvent.cache_creation_input_tokens` / `cache_read_input_tokens` default to 0 — already proven by `FakeNoCacheProvider` round-trip in `tests/grade/test_drift_detector.py`. No schema bump. | +| **Reproducibility hashes** | pass | `rubric_hash`, `prompt_version_template`, `criterion_prompt_hash`, `response_text_hash` are LLM-content-agnostic. OpenAI responses produce a different `response_text_hash` (different judge model output) but the same 16-hex blake2b-8 shape. | +| **Exception taxonomy** | pass | OpenAI SDK exceptions map cleanly: `AuthenticationError`/`PermissionDeniedError` → AUTH; `RateLimitError` → RATE_LIMIT; `APIConnectionError` → CONNECTION; `APIStatusError` with 5xx → SERVER_ERROR; 4xx-non-auth + anything else → NO_RETRY. Mirrors `AnthropicProvider.classify_exception`. | +| **JSON parser tolerance** | pass | `parse_grade_response` already routes through `extract_json_payload` (issue #144) which strips prose preambles. No prefill needed (OpenAI Chat Completions doesn't support assistant-turn prefill either — same constraint as `claude-sonnet-4-6`). Optional refinement: set OpenAI's `response_format={"type":"json_object"}` to enforce JSON server-side. | +| **Live gated test** | pass | Add `@pytest.mark.openai` marker; gate on `SF_RUN_OPENAI=1` + `OPENAI_API_KEY`; register in `pyproject.toml` `[tool.pytest.ini_options].markers` + add to `addopts -m 'not ...'` exclusion. Mirrors the `anthropic` marker precedent. | +| **`--estimate` parity test** | concern | Need a unit-level estimate test with `grade.provider: openai` driving a `FakeOpenAIClient` + faked-or-real tiktoken count, asserting the report renders correctly. | +| **Observability / logger gate** | pass | Lazy-format JSON logger gate (`tests/llm/test_logger_grep_gate.py`) already scans `src/signalforge/llm`. New `_openai_client.py` falls under the gate automatically. No new logger calls planned in the shim — logging stays in `client.py`. | +| **Documentation surfaces** | concern | `docs/grade-ops.md` needs an OpenAI section (config snippet, no-cache caveat, model id guidance, env var). `docs/cost-estimate-ops.md` (or wherever `--estimate` ops live) needs the tiktoken note. `CLAUDE.md` "Related projects" doesn't need a change. `.claude/rules/llm-drafter.md` adds a sub-section on the OpenAI shim + Chat Completions adapter pattern as the precedent for #137. **Resolution:** dedicated docs story. | +| **CHANGELOG** | pass | Add a `0.3.0.dev` entry under "Added" for OpenAI grading. | + +**Blockers:** none. **Concerns:** 6 listed — all routed to refinement or absorbed into specific stories. No architectural blockers. + +## Refinement log + +### Phase 1 scoping decisions (operator-facing) + +- **DEC-001 — OpenAI API surface: Chat Completions.** `client.chat.completions.create(...)` is the stable, universal surface; read text from `response.choices[0].message.content`.

From SD-1. +- **DEC-002 — No cross-validation of provider/model.** `GradeConfig.model` / `DraftConfig.model` stay free strings. The provider registry validates the provider name; the model id is checked at API call time. Model naming evolves too fast (gpt-4o → gpt-4.1 → next) for a hard allowlist to be worth maintaining. From SD-2. +- **DEC-003 — `--estimate` fully wired for OpenAI.** Generalise the estimate-path token-counting through a new `LLMProvider.estimate_input_tokens(model, text) -> int` ABC method. Anthropic impl calls `client.messages.count_tokens(...)` (preserves byte-identity); OpenAI impl uses `tiktoken` (local BPE, no API call). Add OpenAI pricing SKUs. From SD-3. +- **DEC-004 — Default judge model: `gpt-4o`.** Used in docs examples + gated live tests. `GradeConfig.model` / `DraftConfig.model` keep their `claude-sonnet-4-6` default — operators selecting OpenAI explicitly set the model. From SD-4. + +### Phase 3 refinement decisions + +- **DEC-005 — Scope both grade AND draft explicitly.** `OpenAIProvider` is global once registered (provider field on both configs is symmetric since #135). Ship both stages with tests, docs sections, and live smokes. The work is mechanical; asymmetric documentation would imply a non-existent guard. The two stages share one provider class, one shim, one set of pricing SKUs — the *test/docs surface* doubles, not the implementation. +- **DEC-006 — Server-enforce JSON via `response_format={"type":"json_object"}`.** `OpenAIProvider.build_create_kwargs` attaches the JSON-mode flag. Belt-and-braces with the existing tolerant `extract_json_payload` parser: server-side enforcement eliminates the prose-preamble drift class (mirrors issue #144's fix for `claude-sonnet-4-6`), and the parser remains the fallback if a future model strips the flag. The grade system prompt already names "JSON" so OpenAI's prompt-requirement check passes. +- **DEC-007 — Ship four OpenAI SKUs in `pricing.py`.** `gpt-4o` (default judge per DEC-004), `gpt-4o-mini` (budget tier), `gpt-4.1` (newer flagship), `gpt-4-turbo` (back-compat). Each carries `input_per_mtok` + `output_per_mtok`; cache fields are `0.0` (OpenAI has no equivalent cache discount). Bump `PRICE_TABLE_VERSION` to the ship date. +- **DEC-008 — Live gated smoke covers `grade_artifacts`, `draft_schema`, AND `--estimate`.** Three `@pytest.mark.openai` tests gated on `SF_RUN_OPENAI=1` + `OPENAI_API_KEY`: one drives end-to-end grading against the real API; one drives end-to-end drafting (honors DEC-005's both-stages scope at live level too); one runs `signalforge generate --estimate` with `grade.provider: openai` and asserts the report renders. Mirrors the maintainer-only `anthropic` marker precedent and #137's three-live-test breadth. + +### Phase 2 architecture-concern resolutions + +- **DEC-009 — `OpenAIProvider.make_client()` returns a thin `.messages`-shaped adapter.** OpenAI SDK exposes `client.chat.completions.create(...)`; the orchestrator hard-calls `client.messages.create(**kwargs)`. The adapter pattern: `_OpenAIClientAdapter` has a `.messages` namespace whose `.create(**kwargs)` delegates to the underlying `openai.OpenAI().chat.completions.create(**kwargs)`. `.messages.count_tokens` raises `NotImplementedError` defensively (orchestrator never calls it for a `supports_token_count=False` provider). +- **DEC-010 — `_openai_client.py` is the sole home of every OpenAI SDK ignore; add a new 9th AST scan.** Scan 3 in `tests/test_audit_completeness.py` is Anthropic-specific (`anthropic.Anthropic(...)`); adding the OpenAI confinement requires a **new** AST scan, not an extension — bumping the project tally from 8 → 9 (and to 10 once #137's Gemini scan lands; whichever vendor merges first owns the 8 → 9 bump and the second owns 9 → 10). The new scan reuses the existing `_QualifiedNameCallFinder` helper per `testing-signal.md` § "AST single-construction-seam scans must catch all three bypass patterns" (bare / import-alias / module-attribute). Excludes `_openai_client.py`; sanity check asserts ≥1 legitimate `openai.OpenAI(...)` construction lives in the shim. Companion per-file confinement test `tests/llm/test_openai_client_confinement.py` mirrors the Snowflake-shaped `# type: ignore` line scan. +- **DEC-011 — `OpenAIProvider.build_count_tokens_kwargs` raises `NotImplementedError`.** Matches `FakeNoCacheProvider.build_count_tokens_kwargs` precedent. The orchestrator never invokes it (`supports_token_count=False`), but the ABC requires the method present; raising is the honest behaviour. +- **DEC-012 — `tiktoken` lives in the `[openai]` extra, lazy-imported in the shim; dual-listed across all three dev slots.** Mirrors Snowflake's `[snowflake]` precedent verbatim per `python-build.md` § "uv-managed dev environment": `openai>=1.40,<3.0` AND `tiktoken>=0.7,<1.0` appear in **three** places in lockstep — `[project.optional-dependencies].openai` (operator install: `pip install signalforge-dbt[openai]`), `[project.optional-dependencies].dev` (pip back-compat for `pip install -e ".[dev]"`), and `[dependency-groups].dev` (uv-native, what CI uses). Missing any one slot drifts the install surfaces. `uv.lock` refreshes in the same commit. `_count_openai_tokens(model, text)` uses `tiktoken.encoding_for_model(model)` with a `cl100k_base` fallback for unknown ids. +- **DEC-013 — Anthropic estimate byte-identity is the floor.** Before the estimate refactor, capture a golden snapshot of `signalforge generate --estimate` stdout for an Anthropic-config fixture. After the refactor (DEC-003 — strategy-driven token counting), the snapshot must reproduce byte-for-byte. Pin via `tests/cli/test_estimate.py`. +- **DEC-014 — `_load_openai_exception_classes()` returns empty tuples on `ImportError`.** Mirrors `_load_anthropic_exception_classes`'s `pragma: no cover` branch exactly. If a base install ships without the `[openai]` extra, `import openai` raises and the loader returns a frozen `_OpenAIExceptionClasses` with empty tuples in every category. `OpenAIProvider.classify_exception` then routes every exception to `NO_RETRY` cleanly — the operator never gets `provider: openai` to resolve a real call (the registry validator at config load would fail first, since the registration also runs lazily), but import-time behaviour is graceful. **Refusal / content-filter symmetry note:** OpenAI returns refusals as model-generated text (e.g. "I cannot help with that") rather than via a typed exception. The grade parser's tolerant JSON extraction (issue #144) treats unparseable refusal text as `GradeOutputError(violation_type="json_parse")` → standard degrade. No Gemini-style `safety_filter → typed degrade` DEC is needed; the existing pipeline handles it. + +## Detailed breakdown + +Stories follow the natural ordering: dependency wiring → shim → provider strategy → fakes/tests → pricing → estimate refactor → live smokes → docs → QG → P&M.

Mirrors `_anthropic_client.py` exactly. | +| **Performance** | concern → accepted | No caching ⇒ every grade call ships full system+rubric prompt. For default 4 criteria × ~12 artifacts = ~48 sequential calls, this is the dominant cost. Documented as cost guidance in `docs/grade-ops.md`; explicit Gemini caching deferred. | +| **Capability degrade** | pass | Both flags `False`. Identical path to `FakeNoCacheProvider` which #135 already proves end-to-end. No new orchestrator branches. | +| **Safety filter / no-content** | pass | Detected in `extract_text_blocks`; routes via `LLMResponseFormatError` → `GradeLLMError` → degrade. Pinned by a dedicated test driving `FakeGeminiClient.expect_create(returns=)`. | +| **Exception taxonomy** | pass | Five categories cover Gemini's `google.genai.errors` surface (auth via 401/403 on `ClientError`; 429 → RATE_LIMIT; 5xx via `ServerError` → SERVER_ERROR; connection-flavoured → CONNECTION; default NO_RETRY). Mapper unit-tested offline against genuine SDK exception instances. | +| **Config / registry validation** | pass | `provider="gemini"` validates the moment `register_provider(GeminiProvider())` runs at module import (`signalforge.llm.providers`). `UnknownProviderError` lists registered providers; no Pydantic wrap. | +| **Reproducibility hashes** | pass | `rubric_hash`, `prompt_version_template`, `criterion_prompt_hash`, `response_text_hash`, `args_hash` are provider-neutral. Cache-token fields default 0 — already round-tripped by drift detectors. | +| **Testing strategy** | pass | Hand-rolled `FakeGeminiClient` + `expect_*` for offline behaviour; offline exception-map tests use genuine `google.genai.errors.*` instances (SDK is a dev dep); `@pytest.mark.gemini` for live (gated by `SF_RUN_GEMINI=1` + `GOOGLE_API_KEY`). Live tests run `--no-cov`. | +| **Observability** | pass | No new logging beyond what `call_llm` already emits (and most of that is gated off by capability flags). Cleanup-boundary fail-soft N/A — no session state. | +| **`--estimate` integration** | concern → addressed | The ABC extension (`estimate_input_tokens`) ships in #136; #137 implements it via Gemini's native `client.models.count_tokens` and adds 3 Gemini SKUs to `pricing.py`. Documented as DEC-016/017 + US-006/007. **Sequencing: merge after #136** so the ABC + estimate refactor are in place (DEC-019). | +| **Server-side JSON enforcement** | concern → addressed | `extract_json_payload` (issue #144) already tolerates a prose preamble, but server-side enforcement eliminates the drift class entirely. `GeminiProvider.build_create_kwargs` sets `GenerateContentConfig(response_mime_type="application/json")`. Mirrors #136 DEC-006 (`response_format={"type":"json_object"}`). DEC-018. | +| **Pricing-table churn** | pass | `_PRICES_MUTABLE` gains 3 Gemini SKUs (`gemini-2.5-pro`, `gemini-2.5-flash`, `gemini-2.0-flash`) with cache fields = 0.0; `PRICE_TABLE_VERSION` bumps. Additive; no Anthropic SKU moves. DEC-017. | +| **Wheel-build smoke** | pass | New `[gemini]` extra changes packaging metadata. QG runs `uv run pytest -m wheel_smoke --no-cov` per the maintainer marker convention (`python-build.md` § "wheel_smoke maintainer-gate"). | +| **Docs / 5-surface parity** | concern → addressed | Provider list mention in `docs/{draft,grade}-ops.md` ("today only `anthropic` is registered" → "`anthropic`, `openai`, `gemini`" once #136 lands first); cost-guidance bullet about no-caching; `docs/cost-estimate-ops.md` mention of the Gemini estimate path; CONTRIBUTING line for `uv run pytest -m gemini --no-cov`; README provider list; **CHANGELOG entry under `[Unreleased]`**. `.claude/rules/llm-drafter.md` + `grade-layer.md` updates handled by orchestrator-only Patterns & Memory story (Ralph workers can't write `.claude/`, per memory). | +| **Worker-writability** | pass | All shipped code + tests + `docs/` + `README` + `pyproject.toml` + `CHANGELOG.md` are worker-writable. The two `.claude/rules/` updates land in the orchestrator-handled P&M story. | + +No blockers. One concern (performance/cost) accepted with explicit docs; one concern (5-surface parity) addressed by the story split. + +## Refinement log (Phase 3 — decisions) + +- **DEC-001 — Per-vendor shim confinement (mirrors DEC-012 of #5 / DEC-004 of #135).** + `src/signalforge/llm/_gemini_client.py` is the sole module that imports + `google.genai` / `google.genai.errors`. Exposes `GeminiClientProtocol` + (`@runtime_checkable`, duck-typed at the surface `GeminiProvider` consumes), + `_make_gemini_client(api_key=None) -> GeminiClientProtocol`, and + `_load_gemini_exception_classes() -> _GeminiExceptionClasses` (lazy import in the + function body — same shape as `_load_anthropic_exception_classes`).

Pinned + loosely as `google-genai>=0.5,<1` in `[gemini]` and `dev` until v1 stabilises; + bump bounds with each maintainer-driven SDK upgrade (mirrors the `snowflake-connector-python>=3,<4` + pattern). + +- **DEC-003 — Capability flags `False / False`.** `GeminiProvider.supports_prompt_caching + = False` and `supports_token_count = False`. Both branches in `call_llm` degrade exactly + as the `FakeNoCacheProvider` proves: no cache marker, no beta header, cache tokens + reported as 0, no dual-zero WARNING, no pre-send count gate, no `LLMCacheTooLargeError` + pre-send. `cache_marker_active` evaluates `False` regardless (both flags must be `True` + per the QG lesson in #135). `build_count_tokens_kwargs` raises `NotImplementedError` + with an explicit "unreachable when supports_token_count=False" message (matches + `FakeNoCacheProvider`). + +- **DEC-004 — Request shape: system_instruction + single user turn.** `build_create_kwargs` + maps `system` → `config.system_instruction`; concatenates `cached_block + "\n\n" + + dynamic_block` into one user-role `contents` entry. No cache control.

The shim adapts the call shape so + > `call_llm` stays vendor-agnostic. See US-001 / US-002 for the precise façade. + +- **DEC-005 — Safety-filter / no-content → `LLMResponseFormatError`.** `extract_text_blocks` + inspects `response.candidates`. When no candidate yields a non-empty text part (blocked + by safety filter, recitation, length, or any other non-`STOP` finish reason that + produces no content), it raises + `LLMResponseFormatError(f"Gemini response produced no text (finish_reason={fr!r}).")`. + An `LLMError` subclass propagates out of `call_llm` (extraction runs AFTER the retry + loop), so the grade engine wraps it as `GradeLLMError` and degrades the pair with + `reasoning="call failed: GradeLLMError"`. The drafter path surfaces it directly to the + CLI's exit-code tier 2. + + **Refusal / content-filter symmetry with OpenAI (cross-ref #136 DEC-014).** OpenAI + surfaces refusals as **model-generated text** (e.g. "I cannot help with that") which + the tolerant JSON parser routes through `GradeOutputError(violation_type="json_parse")` + → standard degrade — so #136 deliberately ships **no** safety-filter typed-degrade DEC. + Gemini is the opposite: structural blocks produce **no candidate / no text at all**, so + the same parser-degrade path can't catch them; the typed-error branch is load-bearing + here. The two providers' divergent refusal surfaces are why #136 doesn't need this DEC + and #137 does. If a future Gemini SDK release starts returning refusal-as-text in some + cases, the OpenAI parser-degrade path catches it automatically — keep the typed branch + for the structural case it uniquely handles. + +- **DEC-006 — Exception → `ExceptionCategory` taxonomy.** Loaded lazily in the shim: + - `google.genai.errors.ClientError` with `code == 401` or `403` → `AUTH` + - `google.genai.errors.ClientError` with `code == 429` → `RATE_LIMIT` + - `google.genai.errors.ServerError` (5xx family) → `SERVER_ERROR` + - Connection-flavoured: `httpx.ConnectError` / `httpx.TimeoutException` (or the SDK's + wrapped equivalent — verified against the real `google-genai` exception tree at + implementation) → `CONNECTION` + - Anything else → `NO_RETRY` + + Mirrors `AnthropicProvider.classify_exception`. The retry-budget knobs + (`max_retries_429`, `max_retries_5xx`, `max_retries_conn`) on `GradeConfig`/`DraftConfig` + apply unchanged. + +- **DEC-007 — No provider/model coherence check.** `GradeConfig.model` and + `DraftConfig.model` stay free-form `str`. Document the recommended Gemini model id in + `docs/grade-ops.md` § Configuration and `docs/draft-ops.md` § Configuration. An + operator setting `provider: gemini` + `model: claude-sonnet-4-6` fails at the first + API call with a typed `LLMError` from the mapper — late, but not silently wrong. + +- **DEC-008 — API-key resolution via `_make_gemini_client(api_key=None)`.** + `genai.Client(api_key=api_key)`. When `api_key is None`, the SDK reads + `GOOGLE_API_KEY` (or `GEMINI_API_KEY`, depending on SDK version — verified at + implementation). Explicit `api_key=` overrides. No SignalForge-specific env var. Tests + that need a real key set `GOOGLE_API_KEY=...` and gate behind `SF_RUN_GEMINI=1`. + +- **DEC-009 — New AST confinement scan: `genai.Client(...)` only in `_gemini_client.py`.** + Extend `tests/test_audit_completeness.py` with a `_QualifiedNameCallFinder` mirror + matching `Call(func=Attribute(value=Name(id="genai"), attr="Client"))` (and the + three bypass patterns from `testing-signal.md`: bare via `from google.genai import + Client`, import-alias `from google.genai import Client as C`, attribute via + `from google import genai; genai.Client(...)`). The 7th-AST-scan helper already + generalises; reuse it. Sanity test asserts ≥1 construction in + `_gemini_client.py`. **Tally: #137 bumps 9 → 10** (#136 lands the 9th scan for + `openai.OpenAI(...)` first per DEC-019). The docstring "AST scans" tally in + `safety-layer.md` is the surface that needs updating to **10**; the scan-7 + discovery count counts a different thing — per-stage `errors.py` modules — and is + unaffected. + +- **DEC-010 — `pyproject.toml` `[gemini]` extra + dual dev-group listing.** `google-genai` + appears in **three** places, in lockstep (Snowflake precedent): + - `[project.optional-dependencies].gemini = ["google-genai>=0.5,<1"]` (operator + install: `pip install signalforge-dbt[gemini]`). + - `[project.optional-dependencies].dev` (pip back-compat for dev install). + - `[dependency-groups].dev` (uv-native; CI uses this). + + `uv.lock` refreshes in the same commit.

Per S-1 we never `rmtree`, so the `--force`-against-symlink-dest hazard collapses; we still refuse to overwrite if `/.claude/skills/signalforge/SKILL.md` is a symlink (writing follows the link). Path canonicalisation rolled inline like `copy_demo` (NOT via `canonicalise_user_path`, which requires a project_dir — install-skill is the second "creates the project context" entry point alongside `init-demo`, and its module docstring will document this verbatim, citing the `copy_demo` precedent). | +| **API design** | concern | Default `` is `.` (CWD), so the install path becomes `/.claude/skills/signalforge/SKILL.md` — operator runs the command from the dbt project root. Mirrors `init-demo`'s `./signalforge-demo/` ergonomics. Lib seam: `install_skill(dest: Path \| str = ".") -> Path` returns the absolute SKILL.md path. **Concern:** if `/.claude/skills/signalforge/` exists with an unmodelled file alongside SKILL.md, do we report what we preserved? Lock the answer in Phase 3. | +| **Packaging / wheel_smoke** | pass | `include = ["src/signalforge/skills"]` ships the tree recursively (confirmed by the `_demo` precedent — every nested file lands in the wheel without additional globs). `wheel_smoke` extends with a sibling `_EXPECTED_SKILL_FILES` tuple naming SKILL.md + SKILL.eval.json (+ any v0.1 assets). Dotfile-fragility note in `python-build.md` doesn't apply (SKILL.md is not a dotfile). | +| **Observability** | pass | One INFO log line at success: `{"installed": "", "preserved_siblings": [...]}` (lazy-format JSON; raw paths are user-owned, no PII concerns). No DEBUG/WARNING/audit JSONL — install-skill is a deterministic file copy. | +| **Testing strategy** | pass | (1) lib seam unit tests (`tests/skill/test_install.py`) — happy / overwrite-existing / preserve-siblings / SkillDestUnsafeError / SkillPackageDataMissingError. (2) CLI handler tests (`tests/cli/test_install_skill.py`) — main(argv) paths exercising each exit code. (3) Subprocess `--help` smoke under `cli_subprocess` marker. (4) `wheel_smoke` extension. (5) Skill ↔ CLI parity gate (NEW — scope locked in Phase 3). (6) 5-surface parity for `install-skill` itself (no flags in v0.1, so canonical tokens reduce to the subcommand name). | +| **Docs** | pass | New `docs/skills.md` catalog + `mkdocs.yml` nav entry (one line under "CLI Reference"). README "Quick start" gains one sentence after `pip install signalforge-dbt` pointing at `signalforge install-skill`. The shields.io self-grade badge surfaces at the README top per `clauditor`'s precedent. | +| **AST scan #7 (typed-error registry)** | pass | New `signalforge/skill/errors.py` is the **13th** per-stage `errors.py` (current count: 12). Bump `test_scan_7_discovers_every_per_stage_errors_module` count + add `SkillError` to `_EXCEPTION_MAPPING_EXCLUDED_BASES` (its concretes will span tier 1 + tier 2, mirroring `DemoError`/`IngestError`). | +| **Worker-writability** | pass | All shipped artefacts land under worker-writable paths: SKILL.md + assets under `src/signalforge/skills/`; parity gate under `tests/`; rule file under `.claude/rules/skill-parity.md` (orchestrator-only edit). Per `ralph-worker-claude-dir-perms.md` memory, the orchestrator (not a worker) makes the one `.claude/rules/` edit. | +| **Worktree / branch** | pass | Worktree created at `/home/wesd/Projects/worktrees/SignalForge/141-claude-skill-install` on `feature/141-claude-skill-install` off `dev`. | + +No blockers. Two concerns surface as Phase 3 refinement questions: (1) clauditor self-grade +operating model (CI vs pinned-at-release), (2) Skill ↔ CLI parity gate token scope. + +## Refinement log + +### Decisions + +- **DEC-001 — Skill source path.** Package-data tree at + `src/signalforge/skills/signalforge/SKILL.md` (plural `skills/` parent allows future + sibling skills; matches `.claude/skills//SKILL.md` install destination shape; + matches the anticipatory `skill-parity.md` rule verbatim). NO `__init__.py` under + `skills/` or `skills/signalforge/` — the directory is package-data, NOT a Python + package. Mirrors `src/signalforge/_demo/` exactly. + +- **DEC-002 — Python lib subpackage name.** The runtime code lives at + `src/signalforge/skill/` (singular) — a real Python package with `__init__.py`, + `errors.py`, and the public `install_skill(...)` function. Singular name mirrors + `signalforge.demo`; the package-data tree's plural name is the install destination + convention, not the lib name. Two distinct paths, one each side of the seam. + +- **DEC-003 — Destination policy.** `install_skill(dest, *, ...)` always overwrites + every file SignalForge ships (SKILL.md + SKILL.eval.json + any `assets/*` we + enumerate from the bundled tree); never touches any other file in the dest dir. No + `--force` flag in v0.1. Friendlier for upgrade-in-place; eliminates the + `--force`-against-symlink-dest hazard that `copy_demo` defends against because we + never `rmtree`. + +- **DEC-004 — Default destination.** Positional `` defaults to `"."` (CWD). The + effective install path is `/.claude/skills/signalforge/SKILL.md`. Mirrors + `init-demo`'s default-to-CWD ergonomics. The operator runs from the dbt project root. + +- **DEC-005 — Symlink defence (mirror `copy_demo` verbatim).** `install_skill` resolves + `` via `.resolve(strict=True)` first; falls back to `.resolve(strict=False)` on + `FileNotFoundError` / `NotADirectoryError` (common — dest dir may not exist yet); + catches `RuntimeError` (Python ≤3.12) AND `OSError(errno.ELOOP)` (Python ≥3.13) on + cycle detection. Wraps cycle failures as `SkillDestPathError` (tier 1). Additionally: + if `/.claude/skills/signalforge/SKILL.md` exists AND is a symlink, raise + `SkillDestUnsafeError` (tier 2) — writing would follow the link to an arbitrary + destination. + +- **DEC-006 — Path canonicalisation lives in the lib, not via `canonicalise_user_path`.** + `canonicalise_user_path` enforces a `project_dir` containment boundary. `install-skill` + is the second "creates the project context" entry point (alongside `init-demo`) where + no project_dir applies. The lib seam rolls its own resolution mirroring + `signalforge.demo.copy_demo`; the module docstring documents the precedent verbatim. + +- **DEC-007 — Package-data lookup.** Mirror `copy_demo` verbatim: + `files("signalforge").joinpath("skills").joinpath("signalforge")` wrapped in + `as_file(...)` for zipapp/zipimport safety. Failure to find the bundled tree raises + `SkillPackageDataMissingError` (tier 1) — signals a corrupted install. + +- **DEC-008 — Error hierarchy.** + - Lib (`signalforge.skill.errors`): + - `SkillError(Exception)` — abstract base; `extra="forbid"` is N/A (not a Pydantic + model); `__str__` renders `message` + optional `↳ Remediation:` line per + `manifest-readers.md` § "Errors carry remediation." + - `SkillDestPathError(SkillError)` — tier 1; symlink cycle / containment failure. + - `SkillDestUnsafeError(SkillError)` — tier 2; dest is a file (not dir), SKILL.md is + a symlink, dest permission denied at write time. + - `SkillPackageDataMissingError(SkillError)` — tier 1; bundled SKILL.md absent. + - CLI (`signalforge.cli.errors`): + - `CliInstallSkillPathError(CliError)` — tier 1; wraps `SkillDestPathError`. + - `CliInstallSkillDestUnsafeError(CliError)` — tier 2; wraps `SkillDestUnsafeError`. + - `CliInstallSkillPackageDataMissingError(CliError)` — tier 1; wraps + `SkillPackageDataMissingError`. + - **Concretes span tiers 1 + 2**, so `SkillError` joins `DemoError` / `IngestError` + pattern: register only in `_EXCEPTION_MAPPING_EXCLUDED_BASES`, never in the + `_EXCEPTION_TO_EXIT_CODE` table. + +- **DEC-009 — AST scan #7.** Bump + `test_scan_7_discovers_every_per_stage_errors_module` count 12 → 13 in lockstep + with `signalforge/skill/errors.py` landing. Add `SkillError` to + `_EXCEPTION_MAPPING_EXCLUDED_BASES` (frozenset). Register every concrete CLI wrapper + (`CliInstallSkillPathError` / `CliInstallSkillDestUnsafeError` / + `CliInstallSkillPackageDataMissingError`) AND every lib concrete (`SkillDestPathError` + / `SkillDestUnsafeError` / `SkillPackageDataMissingError`) in + `_EXCEPTION_TO_EXIT_CODE` (defence-in-depth: both layers in the table even though MRO + walk would resolve the lib raise via the CLI wrapper). + +- **DEC-010 — Wheel packaging.** Extend `[tool.hatch.build.targets.wheel].include` to + `["src/signalforge/_demo", "src/signalforge/skills"]`. The directory-level include + is transitive — every nested file (SKILL.md, SKILL.eval.json, assets/*) ships + recursively. Confirmed by the `_demo` precedent (recursively ships nested + `models/staging/*.sql`, `target/*.json`). + +- **DEC-011 — `wheel_smoke` extension.** Add `_EXPECTED_SKILL_FILES` tuple alongside + `_EXPECTED_DEMO_FILES` in `tests/test_wheel_packaging.py`. v0.1 set: + `("signalforge/skills/signalforge/SKILL.md", + "signalforge/skills/signalforge/assets/SKILL.eval.json")`. Run via + `uv run pytest -m wheel_smoke --no-cov`. Also add a NEGATIVE assertion: no + `.claude/skills/*` paths appear in the built wheel (defence against accidentally + including maintainer-only `release-manager` / `review-agentskills-spec` — they live + at repo-root `.claude/skills/`, outside `src/`, so they're already excluded, but + the negative assertion documents intent). + +- **DEC-012 — e2e demo paths (both, with live gated).** Zero-credential default: + `signalforge init-demo /tmp/signalforge-demo` → `signalforge generate + models/staging/stg_bikeshare_trips.sql --write` (schema-only mode by default) → + walk through the kept / kept-uncertain / dropped / flagged diff. Live e2e (opt-in): + the skill body forces an explicit user confirmation ("This will run paid LLM + + warehouse queries — proceed?"), checks `SF_RUN_BQ`, `GOOGLE_CLOUD_PROJECT`, + `ANTHROPIC_API_KEY` (clean skip-with-reason when absent), then invokes + `uv run pytest -m e2e --no-cov`. Cost warning before invocation. + +- **DEC-013 — `allowed-tools` scope.** Comma-separated: + `Bash(signalforge *), Bash(uv run signalforge *), Bash(uv run pytest -m e2e*), + Bash(cat *), Bash(ls *), Bash(grep *), Bash(head *), Bash(tail *), + Read, Write, Edit`. The `pytest -m e2e*` scope is required for the live-gated path + per DEC-012; the skill body's confirmation gate is the user-facing defence. + +- **DEC-014 — Self-grade operating model.** Pre-release manual run. + Maintainer runs `clauditor grade src/signalforge/skills/signalforge/SKILL.md` locally + before tagging a release; captures the score; pins it in + `src/signalforge/skills/signalforge/assets/SKILL.eval.json`. README badge surfaces the + pinned score via shields.io. Same commit updates SKILL.md + eval.json + README + badge. No CI integration, no Anthropic key in repo secrets, no per-PR cost. Adds + `clauditor` to `[dependency-groups].dev` if not already present. + +- **DEC-015 — Parity gate scope.** New test + `tests/cli/test_skill_cli_parity.py` scans for three categories of tokens, all of which + must appear verbatim in `src/signalforge/skills/signalforge/SKILL.md`: + 1. Every subcommand name from the live argparse parser (auto-grows). Source: + `signalforge.cli._build_parser()` → walk `parser._subparsers._group_actions[0].choices`. + Current v0.2 set: `generate`, `lint`, `prune-existing`, `init-demo`, `install-skill`, + `version`. + 2. The four canonical demo command lines: `signalforge init-demo`, + `signalforge generate --write`, `signalforge prune-existing --schema + `, `signalforge install-skill`. Plain substring match — no regex, no whitespace + normalisation (mirrors envelope-breach guard pattern from `business-rule-tests.md`). + 3. The install-skill bootstrap line itself (`signalforge install-skill`). + The gate is mechanical, not semantic — semantic freshness lives in the clauditor self-grade. + +- **DEC-016 — Parity gate is a NEW test, not an extension of 5-surface parity.** The + 5-surface parity tests in `tests/cli/test_5_surface_parity_*.py` pin canonical tokens for + ONE subcommand across five surfaces (help/docstring/ops/plan/test). The skill parity + gate scans the FULL CLI surface against ONE skill body. Different shape, different + failure modes; keeping them as separate tests preserves the locality of each gate's + failure message. + +- **DEC-017 — Overwrite UX.** Single INFO line on success: + `Installed SignalForge skill to `.

A `finish_reason="MAX_TOKENS"` response that produces a partial (truncated mid-string) text part silently returns, the truncated JSON reaches `parse_grade_response`, the grade engine wraps the resulting `GradeOutputError(violation_type="json_parse")` as a degraded result with `reasoning="call failed: GradeOutputError"` — masking the actionable typed degrade (`"call failed: GradeLLMError"`) that `llm-drafter.md` § "Gemini provider shape" DEC-005 of #137 contracts. The same class of bug exists latently in OpenAI (`finish_reason="length"`) and Anthropic (`stop_reason="max_tokens"`); the fix is provider-neutral. + +2. **Flake (tactical).** `tests/grade/test_gemini_grade_live.py:142` sets `max_output_tokens=512`; Gemini 2.5-flash's verbose `reasoning` field routinely exceeds that on the smoke fixture's 5 pairs, hitting MAX_TOKENS. Verified passing at 2048. + +3. **E2E gap (structural).** No live full-pipeline `signalforge generate` test exists for OpenAI or Gemini — only the BigQuery + Anthropic e2e (`tests/cli/test_e2e_bigquery_smoke.py`). The three grade-only live smokes exercise `grade_artifacts()` in isolation; they never see drafter, prune, diff, or sidecar seams with a non-Anthropic provider. Finding 1 is a worked example of drift the in-isolation test surfaced only because the rendered output failed parse — a full-pipeline smoke would have hit it the same way plus all surrounding contracts. + +## Discovery (summary) + +- **Bug location:** `src/signalforge/llm/providers.py:867-897` — early `if blocks:` return at line 888-889 swallows partial text. `finish_reason` is at `candidates[0].finish_reason.name`. +- **Existing safety-filter contract pin:** `tests/grade/test_gemini_neutrality.py:381` already asserts `bad.reasoning == "call failed: GradeLLMError"` — the fix makes MAX_TOKENS land on the same assertion. +- **E2E template:** `tests/cli/test_e2e_bigquery_smoke.py` (~49 LLM calls/run, 7 invariants). `tests/cli/test_e2e_snowflake_smoke.py:225-241` shows the `textwrap.dedent` `signalforge.yml` overlay pattern. +- **Markers:** `pyproject.toml` already registers `openai` + `gemini` and excludes them from default `addopts`. +- **Austin fixture Anthropic-isms:** Only `llm.model: claude-sonnet-4-6`.

Gemini's verbose `reasoning` provably needs ≥1024; 2048 verified safe in #155 probe. **Reframed by #158 (2026-05-28):** the 2048 "verified safe" claim was scoped to the 5-pair in-isolation probe (`tests/grade/test_gemini_grade_live.py`). The first full-pipeline e2e run against Gemini surfaced 5–6/108 pairs still degrading at 2048 on the Austin bikeshare fixture — Gemini's per-pair `reasoning` is high-variance enough that the in-isolation floor is not the full-fixture floor. The docs table now reads **4096** for Gemini, framed as "fixture-scale-dependent" rather than a single safe number; this DEC stays as the historical record of the 2048 figure's provenance.

At ~2-3 pre-release audits/month that lands at roughly **$2.76-$4.14/month** for a one-maintainer project. Env-var gating is already explicit; a shell wrapper adds surface area without changing the contract.

Helper makes future re-measurement boring; baseline gives the docs a concrete number today. +- **DEC-Q3 — Xdist shape:** Add `pytest-xdist` to `[dependency-groups].dev` + mirror; document `uv run pytest -m e2e -n 3 --no-cov` as the recommended maintainer invocation in CONTRIBUTING. **No `addopts` change** — default behaviour stays sequential. +- **DEC-Q4 — Measurement:** Maintainer re-runs the live suite as part of implementation (one story explicitly for this). Helper exists before the run so figures aren't hand-reconstructed. + +## Architecture Review (Phase 2) + +No blockers; three concerns to resolve in refinement. Reviewed the proposed shape (rollup helper as `signalforge.llm.pricing.rollup_audit_dir(...)` library function + thin `scripts/measure_e2e_cost.py` wrapper, `pytest-xdist` as opt-in dev dep, live re-run as part of impl). + +| Review area | Rating | Findings | +|---|---|---| +| **Security** | pass | Helper reads only token-count + model-id fields, never echoes `evidence`/`reasoning`. Path safety must route through `signalforge._common.path_safety.canonicalise_path` (the convention for any user-supplied path; `manifest-readers.md`). No credentials surface. Three parallel BigQuery temp-tables on the maintainer's billing project at Austin scale (≪100M rows after sample) are well inside slot quotas. | +| **Performance / cost** | concern | **Anthropic 50 RPM is the tight gate.** With drafter (Anthropic, singleton) + three parallel Anthropic graders the suite can hit ~50 calls in one epoch and trigger the `WARNING: rate limit` retry path (`llm-drafter.md` DEC-005). Gemini 60 RPM and OpenAI 500 RPM are comfortable at `-n 3`. **Wall-clock bound:** test-level parallelism is capped by the *longest* test (the BQ smokes at ~8 min each). With 3 BQ variants + 3 standalone smokes, `-n 3` can in principle pack three ~8 min tests into one ~8 min wave + three shorter tests into another, so the floor is ~16-18 min vs 39 serial. Real speedup needs measurement — DEC-Q4 covers that. **Recommendation:** document `-n 3` with the rate-limit caveat + monitoring guidance, allow maintainer to downgrade to `-n 2` if Anthropic retries spike. | +| **Data model / API** | pass | The rollup return shape ships as `@dataclass(frozen=True) CostReport` (NOT Pydantic), so it sidesteps the `extra="ignore"` + drift-detector contract — it's a pure compute output, never serialised to a JSONL/sidecar that downstream consumers read back. No `audit_schema_version` bump: the helper consumes existing `LLMResponseEvent` / `GradeEvent` fields only (`input_tokens` / `output_tokens` / `cache_creation_input_tokens` / `cache_read_input_tokens` / `model`). | +| **Observability / fail-soft** | concern | Helper needs ~3 typed errors: `CostRollupAuditMissingError` (neither JSONL present), `CostRollupMalformedRecordError(line_num, reason)` (bad JSONL line), `CostRollupUnknownModelError(model_id)` (pricing-table miss). Each carries `default_remediation` per the `manifest-readers.md` rule. **Decision:** does it need its own subpackage `signalforge.llm.cost` with `errors.py`, or extend `signalforge.llm.pricing` with the new functions + typed errors? The latter avoids growing scan-7's "exactly 11 errors.py modules" count (`cli-layer.md`). | +| **Testing strategy** | pass | Helper is unit-testable against `tests/fixtures/draft/llm_response_*.json` + `tests/fixtures/grade/grade_event_v1.jsonl` + the frozen `PRICES` table. Add deterministic micro-fixtures for the rollup arithmetic. **pytest-xdist interaction with maintainer-only markers:** `cli_subprocess` (5 tests in one file → no parallel collision risk on the installed wheel), `wheel_smoke` (one test, builds wheel into a temp dir → no shared-state risk). Recommendation: only `e2e` gets the `-n 3` recommendation; serial stays the default for `cli_subprocess` / `wheel_smoke` invocations. | +| **CONTRIBUTING / docs** | concern | `CONTRIBUTING.md` § "Live e2e suite (pre-release only)" at line 96 IS the section to update (line 106 has the `$0.30` figure). **Latent doc gap to fix in this plan:** `test_e2e_business_rules.py` IS marked `@pytest.mark.e2e` but is NOT listed in CONTRIBUTING's enumeration (lines 119-148 list only the four BQ/OpenAI/Gemini/Snowflake files). Plan must add the business_rules entry to the list. `docs/grade-ops.md` § Cost guidance needs per-provider USD rows (Anthropic + OpenAI + Gemini) — current text has only the Sonnet figure. `plans/super/155-…md` DEC-010 update is the small change. `docs/cost-estimate-ops.md` documents the `--estimate` preview, separate concern, no cross-reference needed. | + +### Concerns to resolve in Refinement + +- **C1.** Concurrency level — recommend `-n 3`, `-n 2`, or no specific number? +- **C2.** Helper home — `signalforge.llm.pricing` extended in-place, or new `signalforge.llm.cost` subpackage? +- **C3.** Doc-gap scope — fix the missing `business_rules` enumeration entry as part of this plan, or file separately? + +## Refinement Log (Phase 3) + +### Decisions + +- **DEC-001 — `-n 3` is the recommended xdist concurrency, with documented Anthropic rate-limit caveat.** + - *Rationale:* Anthropic 50 RPM is the tight gate; OpenAI 500 RPM + Gemini 60 RPM are comfortable. `-n 3` gives a target wall-clock of ~13-18 min vs ~39 serial; if `_LOGGER.warning("…rate limit…")` events spike in stderr during a real run, the maintainer downgrades to `-n 2`. CONTRIBUTING documents the tuning knob explicitly. + +- **DEC-002 — Cost rollup ships as a new `signalforge.llm.cost` subpackage with its own `errors.py`.** + - *Rationale:* Aligns with the per-stage `errors.py` convention. The 3 typed errors all map to CLI tier 2 (input-validation); the `CostError` base also gets a dual-registration at tier 2 (the safety-net pattern from `cli-layer.md` — same shape as `ManifestError` → tier 1). Scan-7's glob currently walks `src/signalforge/*/errors.py` (depth 1) — extending it to also discover `src/signalforge/*/*/errors.py` is a one-line shape change + a bump of the expected-paths list from 11 → 12. This is the first sub-stage `errors.py`; the convention generalises cleanly for future sub-packages. + +- **DEC-003 — `test_e2e_business_rules.py` enumeration doc gap is fixed in the same CONTRIBUTING update.** + - *Rationale:* Same surface, same touch, logical to bundle. Avoids a follow-up ticket for a one-line list addition. + +- **DEC-004 — Return shape is `@dataclass(frozen=True) CostReport`, not Pydantic.** + - *Rationale:* The rollup output is a pure compute result, never serialised to a JSONL/sidecar that downstream consumers read back. A frozen dataclass sidesteps the `extra="ignore"` + drift-detector contract that `manifest-readers.md` mandates for any read-back Pydantic model. Carries `per_provider: Mapping[str, ProviderRollup]` (also frozen dataclass) + `total_usd: float` + `pricing_table_version: str` (stamps `signalforge.llm.pricing.PRICE_TABLE_VERSION`). + +- **DEC-005 — Helper is read-only; no fail-closed writer; symlink-hardened path canonicalisation at entry.** + - *Rationale:* Routes the supplied `project_dir` through `signalforge._common.path_safety.canonicalise_path` per `manifest-readers.md` § "Symlink-hardened path resolution". Hardcodes the `.signalforge/` subdir relative to canonicalised `project_dir` (matches the convention in `signalforge.grade` and `signalforge.draft`). No new fail-closed writer to register in scan-8. + +- **DEC-006 — `scripts/measure_e2e_cost.py` is repo-only, NOT shipped in wheel.** + - *Rationale:* Per `python-build.md`, the wheel's `[tool.hatch.build.targets.wheel]` explicitly lists what ships. The maintainer audit script lives alongside future regen scripts and never appears on a user's `pip install signalforge-dbt`. First entry in a `scripts/` directory; sets the precedent. + +- **DEC-007 — `pytest-xdist` lands in `[dependency-groups].dev` AND `[project.optional-dependencies].dev`, mirrored.** + - *Rationale:* `python-build.md` § "uv-managed dev environment" mandates the two lists stay in sync for `uv sync --dev` + `pip install -e ".[dev]"` parity. No `addopts` change — opt-in invocation only. + +- **DEC-008 — Maintainer live re-run is its own story.** Bead is marked maintainer-only at devolve; closes when measured baseline lands in this plan's refinement log. + +- **DEC-009 — Durable convention captured in `testing-signal.md` § "End-to-end gated tests"** — the "parallel-safe via per-test tmp_path + apply_provider_override" rule plus the rate-limit-caveat invocation pattern.

Rollup computed by `scripts/measure_e2e_cost.py` over each test's preserved `tmp_path/.signalforge/` JSONLs at `/tmp/pytest-of-wesd/pytest-629/`. **`PRICE_TABLE_VERSION = "2026-05-28"`** (from `signalforge.llm.pricing`). + +**Wall-clock:** `14:53` (893.35s) at `-n 3` vs the ticket-cited `39:23` serial baseline → **~2.6× speedup**. Test scheduling: 3 xdist workers, each running 2 tests sequentially. Per-test wall-clock is not cleanly extractable from xdist parallel output; the gw2 worker's first test (Gemini-grader sibling, inferred from progress output — xdist doesn't surface per-test wall-clock cleanly) completed in ~9 min, and each worker finished both tests within 14:53. + +**Rate-limit retries:** **zero** observed in stderr. Grep for `rate limit` / `429` / `retry` over the full log returned no matches. The Anthropic-50-RPM concern documented in CONTRIBUTING did not materialise at `-n 3` against the Austin fixture — the per-test grade-call cadence is more spread out than worst-case calculation suggested. **Concurrency: `-n 3` was safe; no downgrade needed.** + +**Per-test USD (locked by JSONL token rollup × `PRICES` table):** + +| Test (pytest tmp basename) | Drafter | Grader | Calls | USD | +|---|---|---|---|---| +| BQ smoke `[anthropic]` (gw0 #0) | Anthropic | Anthropic | 105 | **$0.3822** | +| BQ smoke `[openai]` *or* `openai_smoke` (gw0 #1) | Anthropic | OpenAI gpt-4o | 1 + 108 | **$0.2550** | +| `business_rules` (gw1 #0) ⚠ | Anthropic | Anthropic | 89 | **$0.3218** | +| BQ smoke `[gemini]` *or* `gemini_smoke` (gw1 #1) | Anthropic | Gemini 2.5-flash | 1 + 108 | **$0.0881** | +| Sibling smoke (gemini grader, gw2 #0) | Anthropic | Gemini 2.5-flash | 1 + 104 | **$0.0843** | +| Sibling smoke (openai grader, gw2 #1) | Anthropic | OpenAI gpt-4o | 1 + 108 | **$0.2476** | + +Within each `(openai|gemini)` row pair, identifying which is the BQ parametrize variant vs the standalone sibling is not load-bearing for cost (both ran the full pipeline; both produced kept/dropped diffs).

This is LLM-determinism on the drafter side, not a bug in US-001…US-004 or in `-n 3` parallelization. The test still ran to completion and emitted all four `.signalforge/` JSONLs; cost rollup is unaffected. Filed as [#163](https://github.com/wjduenow/SignalForge/issues/163) — the drafter ignored both injected business rules and hallucinated a third (`WHERE duration_minutes <= 0`); investigation directions live in the issue. + +**Framing for US-006 (cited verbatim in the doc updates):** "calibration signal, not a billing guarantee" per `warehouse-adapters.md` precedent — the figures above are a single 2026-05-29 measurement at `PRICE_TABLE_VERSION=2026-05-28`; vendor pricing rotates and the Austin-fixture artifact count is workload-specific. + +### Session notes + +- Codebase Scout confirmed token-cost fields are already on both `LLMResponseEvent` (drafter) and `GradeEvent` (grader); no `audit_schema_version` bump needed.

BigQuery rejected the query; the prune engine correctly routed to `kept-without-evidence` per the conservative-bias contract; the test asserts `kept` with positive evidence and fails. + +Root cause: **the Austin fixture's `manifest.json` has `data_type: null` for every column.** The full drafter / safety / prompt-rendering pipeline already supports column types — both the cached manifest summary (`prompts.py:347`) and the dynamic data section (`safety/request.py:161`) read `Column.data_type` and render it into the LLM prompt — but the input is empty for this fixture, so the LLM sees no type information and guesses. + +## Discovery — key findings + +1. **`Column.data_type` is already wired end-to-end in production code.** The drafter does NOT need to "learn" types. The cached block renders `- {name} ({data_type or "UNKNOWN"}): {description}` at `src/signalforge/draft/prompts.py:347`. The dynamic block's data section receives `request.schema` as `tuple[(name, type_str)]` from the safety layer at `src/signalforge/safety/request.py:161`, where `type_str = column.data_type or ""`. + +2. **`dbt parse` does NOT populate `data_type`.** Only `dbt docs generate` (which produces `catalog.json`) carries column types. The Austin fixture was generated by `dbt parse` against bikeshare; its `data_type` fields are null. **Real users running `dbt docs generate` would already get types** — this is partially a fixture problem. + +3. **No parser-level type-mismatch check.** `_validate_anchor_contract` in `src/signalforge/draft/parser.py:87–191` is purely structural — column-set membership + test-column linkage. There is no defence catching a type-mismatched `custom_sql` post-LLM-response. Prompts are advisory; if we depend on the LLM honoring types, we want dual-defence. + +4. **Cache rotation risk is bounded.** The cache-stability golden (`tests/llm/test_prompt_cache_stability.py:71` pins `_EXPECTED_PROMPT_VERSION = "c9e7ee1f6f465933"`) uses the `fct_orders` fixture, NOT bikeshare. Populating the Austin fixture's `data_type` fields does NOT touch the golden. Template-text changes WOULD rotate the version. + +5. **`Column.data_type` is already in the public Pydantic model** (`src/signalforge/manifest/models.py:97`) as `str | None = None`, drift-detected. No model surgery needed. + +6. **Same fixture serves multiple e2e tests.** `tests/fixtures/dbt_project_austin/target/manifest.json` is used by both `test_e2e_bigquery_smoke.py` and `test_e2e_business_rules.py`. Populating `data_type` in this manifest will affect the dynamic block bytes for BOTH; only the cache-stability test pins a golden, and it uses a different fixture. + +7. **The warehouse adapter knows types but doesn't surface them to the manifest layer.** `BigQueryAdapter._flush_column_stats_batch` (lines 839–912 in `adapters/bigquery.py`) populates `ColumnStats.data_type: str` from `INFORMATION_SCHEMA`. No path connects this back to `Manifest.Column.data_type` for drafter consumption. + +## Resolution-option tree + +| Option | Description | Cost | Helps real users? | Touches | +|---|---|---|---|---| +| **A.

Per-project rendered bytes have always varied (different manifests → different output); only template edits rotate the version. Populating `data_type` falls under per-project variation. +3. **Cache-stability golden uses `fct_orders` fixture**, which already has populated `data_type` fields (`NUMERIC`, `STRING`, `TIMESTAMP`, `INT64`). The golden is unaffected by anything we do to the Austin fixture or by adding catalog.json merging. +4. **Reviewer disagreement resolved:** One reviewer claimed catalog.json merge requires `_PROMPT_VERSION` rotation; this is incorrect (conflated template-vs-content). The codebase's posture is template-hash only. + + +## Refinement log (Phase 3) — locked decisions + +- **DEC-001 — Scope.** Implement A + B + D: populate `data_type` in the Austin fixture (closes the flake), merge `target/catalog.json` types into `Column.data_type` during manifest load (product value for `dbt docs generate` users), add sqlglot-based type-coherence defence in `_validate_anchor_contract` for `custom_sql` (dual-defence per `llm-drafter.md`). + +- **DEC-002 — Catalog discovery.** Sibling lookup at `/catalog.json`. No new config knob, no CLI flag. Mirrors how dbt itself locates the file. Path is canonicalised via `_common.path_safety.canonicalise_path` (`manifest-readers.md` § Symlink-hardened path resolution). + +- **DEC-003 — Parser defence depth.** Use sqlglot AST type-checking via `optimizer.annotate_types` with a schema map built from `model.columns_list`. The BigQuery dialect's `COERCES_TO` table catches INT64 vs STRING; numeric-family coercions (INT64↔FLOAT64, NUMERIC↔BIGNUMERIC) stay accepted as legitimate. + +- **DEC-004 — Test assertion.** `test_e2e_business_rules_drafts_prunes_custom_sql::has_kept_with_evidence` stays as-is. Engineering the input (types in manifest) makes the assertion mathematically reachable per `testing-signal.md` § Engineered determinism. + +- **DEC-005 — sqlglot dependency.** Promote sqlglot to a direct runtime pin in `[project].dependencies` as `sqlglot>=30,<31`. Currently a dev-only transitive (via `fakesnow`); type-defence correctness is load-bearing and cannot depend on transitive resolution from a dev-only package. Mirror entry in `[project.optional-dependencies].dev` per `python-build.md` § uv-managed dev environment. + +- **DEC-006 — Skip-when-uncertain policy.** The sqlglot type check flags ONLY direct `Column Column` comparison nodes where: + 1. Both operands are bare `Column` AST nodes (NOT `Cast`, `SafeCast`, `Coalesce`, `IfNull`, function calls, subqueries, literals, NULL, window functions) + 2. Both columns appear in the schema map with non-None `data_type` + 3. The two types are not in the `COERCES_TO`-compatible set for the dialect + Every other shape skips silently. `sqlglot.errors.ParseError` from `parse_one` also skips silently (invalid SQL is caught downstream by the warehouse adapter). False-positive avoidance trumps marginal recall. + +- **DEC-007 — Catalog column matching.** Case-insensitive lookup via `lower(col_name)` key. Snowflake's catalog.json uppercases identifiers; BigQuery preserves case. The lower-fold is a strict superset for both warehouses. No logging — manifest layer is stage-0 (`manifest-readers.md` § No logging in stage-0). + +- **DEC-008 — sqlglot import confinement.** Convention only (documented in `.claude/rules/llm-drafter.md`): sqlglot imports live ONLY in `signalforge.draft.parser`. No AST scan in v0.1 (one consumer; the bigger surface that justified AST scans was the 4+ vendor-SDK pattern). Revisit if a second module reaches for sqlglot. + +- **DEC-009 — No `_PROMPT_VERSION` rotation.** `_PROMPT_VERSION = blake2b(_SYSTEM_PROMPT + _MANIFEST_SUMMARY_TEMPLATE + DATA_SECTION_TEMPLATES_JSON)` is a TEMPLATE hash. Per-project rendered bytes have always varied (different manifests → different output); only template-text edits rotate the version. Populating `data_type` from catalog.json is per-project content variation. The cache-stability golden uses `fct_orders` (which already has populated types); golden is unaffected. + +- **DEC-010 — Stale catalog handling.** When catalog.json exists but is stale relative to manifest.json: (a) catalog columns NOT in manifest are silently ignored (never add phantom columns to `Model.columns`); (b) manifest columns NOT in catalog keep `data_type = None` (no change vs. today); (c) `json.JSONDecodeError` / `OSError` reading catalog → silent skip, manifest loads with all `data_type = None`. Conservative-bias: never block load on catalog mismatches. No typed `CatalogError`. + +- **DEC-011 — Error class reuse.** Type-mismatch violations append to the existing `LLMOutputAnchorContractError.violations` tuple. No new error subclass. Saves a CLI exit-code-table entry, a 7th-AST-scan exclusion update, and a 5-surface parity sweep. The violation message names the column, the conflicting types, and the operator (`"custom_sql test references column 'a' (INT64) and 'b' (STRING) in '<>' comparison — types incompatible"`). + +- **DEC-012 — Parser API.** `_validate_anchor_contract` gains two keyword-only parameters: `model_columns_by_type: Mapping[str, str | None] | None = None` (column-name → `data_type` or None) and `dialect_name: str = "bigquery"` (string, not the typed `Dialect` value object — avoids cross-stage import). When `model_columns_by_type is None` OR every column's type is None, the type-coherence arm is a no-op. Threaded through `parse_draft_response` from `draft_from_request`; orchestrator builds the map from `model.columns_list`. + +- **DEC-013 — Dialect threading.** `dialect_name` is sourced from `safety_policy.warehouse_dialect_name` if it exists; otherwise hardcoded to `"bigquery"` at the orchestrator call site with a TODO referencing v0.2 multi-warehouse work. v0.1 supports BigQuery only at the warehouse layer; Snowflake/Postgres are skeletons. + +## Detailed breakdown (Phase 4) + +Architecture ordering — stage-0 reader → drafter → parser → fixtures → docs → quality.

If we tighten the SCOPE instruction text (Lever A), bump the version AND regenerate `tests/llm/test_prompt_cache_stability.py` golden in lockstep. +3. **Prompt-injection envelope guard** (`llm-drafter.md` DEC-007). If we wrap rules in `` tags, `_render_dynamic_block` must raise `PromptEnvelopeBreachError` when any rule contains the closing tag. Mirrors the `` precedent. +4. **Conservative-bias / no new `DropReason`** (`prune-engine.md`). A parser-side rejection of "too few `custom_sql` tests" should surface as `LLMOutputAnchorContractError` (collect-all violations), NOT a new prune drop-reason — the prune stage never sees the rejected candidate. +5. **Gate-over-prompt** (`testing-signal.md`). The fix must be verifiable at unit-test time without an LLM in the loop — a unit test that injects a 2-rule payload and a hand-rolled bad candidate must reject; a 2-rule payload + matching candidate must accept. +6. **Fail-closed audit invariant**: bad-JSON / parse-fail responses still write no audit row.

System-prompt / dynamic-block / parser changes apply uniformly across Anthropic, OpenAI, Gemini — no branching on provider. +9. **Exit-code lockstep** (`cli-layer.md` 7th AST scan). If we introduce a new error class, register it in `_EXCEPTION_TO_EXIT_CODE`. The simplest path — re-use `LLMOutputAnchorContractError` — needs no new entry. +10. **Skill-parity + 5-surface graduation** (`skill-parity.md` / `cli-layer.md`).

System-prompt restructure (Lever A) is held in reserve if Sonnet 4.6 compliance remains low after this fix lands. **Rationale:** gate-over-prompt per `testing-signal.md`; no `_PROMPT_VERSION` rotation; minimal LOC; verifiable without LLM. +- **DEC-002 — Cardinality is at-least-one-per-rule.** `count >= len(business_rules)` accepts. Excess allowed (the LLM may legitimately split a complex rule into two SELECTs). Exact equality conflates over- and under-coverage; per-scope (model vs. column) requires a `rule_id` field we explicitly didn't add. +- **DEC-003 — Unit-level parser tests + reuse existing e2e.** Hand-rolled candidates exercise the new gate without LLM cost. `tests/cli/test_e2e_business_rules.py` is already the live reproduction and certifies the round-trip after the fix. +- **DEC-004 — Thread `business_rules` through `parse_draft_response` (mirror #159).** Keyword-only `business_rules: tuple[str, ...] = ()` on `parse_draft_response` and `_validate_anchor_contract`. Built in `draft_from_request` (`schema.py`) from `_read_business_rules(model)`. Single source of truth; mirrors `model_columns_by_type` threading from issue #159 verbatim. +- **DEC-005 — Reuse `PromptEnvelopeBreachError` with parameterised envelope.** Extend `__init__` with `envelope: str = "MODEL_SQL"` and `rule_index: int | None = None` kwargs (both default-safe; existing call site untouched). Message renders `` or `` per envelope. No taxonomy growth, no new exit-code entry. +- **DEC-006 — Violation message names rules verbatim.** When the parser gate fires, the violation lists every declared business rule (prefixed `(model)` or `(column X)` per the renderer's existing prefix). Since cardinality is at-least-one-per-rule (DEC-002), we can't identify a specific missing rule — the operator gets the full declared set + the actual `custom_sql` count. Message shape pinned by test. +- **DEC-007 — No INFO breadcrumb on rule injection.** The `LLMResponseEvent` audit row already carries `response_text_hash` + the prompt that triggered it. Adding an INFO line per render is noise in default-quiet runs. +- **DEC-008 — `exclude_tests=("custom_sql",)` short-circuits both surfaces.** When the operator forbids `custom_sql`, `_render_business_rules_section` returns `""` (don't tell the LLM to draft rules it can't emit) AND `_validate_anchor_contract` skips the cardinality gate (no rules in scope). Mirrors how `_render_system_prompt(exclude_tests)` already drops `custom_sql` from the catalogue. +- **DEC-009 — Envelope format.** Per rule: opening tag `` on its own line; rule text indented 2 spaces on the next line(s); closing tag `` on its own line.

The rule body still carries the existing scope prefix (`(model)` / `(column X)`) verbatim. +3. `_render_business_rules_section` short-circuits to `""` when `custom_sql` is in `DraftConfig.exclude_tests` (passed in from the renderer via the existing thread). +4. `PromptEnvelopeBreachError.__init__` accepts new keyword-only args: `envelope: str = "MODEL_SQL"`, `rule_index: int | None = None`. Existing single call site in `prompts.py` keeps working unchanged. +5. Rendered message: when `envelope="MODEL_SQL"`, byte-equal to the current `` message; when `envelope="BUSINESS_RULE"`, mentions the rule index (`"… in rule #2 of model.x.y …"`). +6. `_render_business_rules_section` scans each rule for the literal `` substring (boring substring match, no whitespace normalisation per `llm-drafter.md` DEC-007/grade-layer.md envelope-breach precedent) and raises `PromptEnvelopeBreachError(model.unique_id, envelope="BUSINESS_RULE", rule_index=i)`. +7. `uv run pytest tests/draft/test_prompts.py` passes; `uv run pytest tests/llm/test_prompt_cache_stability.py` passes **with no `_PROMPT_VERSION` change** (this is the load-bearing check that we didn't accidentally touch the cached system prompt). +8. Canonical validation command passes. + +**Done when:** new envelope shape renders, breach guard fires loudly on poisoned rules, and `_PROMPT_VERSION` is byte-identical to its pre-fix value. + +**Files:** + +- `src/signalforge/draft/prompts.py` — rewrite `_render_business_rules_section`; thread `exclude_tests: tuple[str, ...]` (or read from the existing config seam); add breach scan. +- `src/signalforge/draft/errors.py` — parameterise `PromptEnvelopeBreachError.__init__`. +- `tests/draft/test_prompts.py` — update `test_business_rules_render_into_dynamic_block` for the new shape; add `test_business_rules_section_short_circuits_when_custom_sql_excluded`; add `test_business_rules_envelope_breach_guard_fires_on_closing_tag`; add `test_business_rules_envelope_breach_message_includes_rule_index`. +- `tests/draft/test_errors.py` *(if exists; otherwise add to nearest)* — pin parameterised `PromptEnvelopeBreachError` message for both envelopes; assert existing `MODEL_SQL` byte-equal. + +**Depends on:** none. + +**TDD:** yes — write the envelope-shape test, breach-guard test, and parameterised-error tests FIRST. Implement until all pass. + +### US-002 — Parser cardinality gate + business_rules threading + +**Traces to:** DEC-001, DEC-002, DEC-003, DEC-004, DEC-006, DEC-008. + +**Description:** Add a keyword-only `business_rules: tuple[str, ...] = ()` to `parse_draft_response` and `_validate_anchor_contract`. Thread it from `draft_from_request` (the orchestrator already builds the rules tuple via `_read_business_rules(model)`). In `_validate_anchor_contract`, when `business_rules` is non-empty AND `custom_sql` is NOT in `exclude_tests`, append one violation if `custom_sql_count < len(business_rules)`. + +**Acceptance criteria:** + +1. `parse_draft_response` signature gains keyword-only `business_rules: tuple[str, ...] = ()` (default keeps every existing call site working). Public-API surface confirmed via `tests/draft/test_public_api.py` (or equivalent). +2. `_validate_anchor_contract` signature gains the same kwarg; existing `model_columns_by_type` threading is the precedent — match its placement and pyright-narrowing style. +3. `draft_from_request` (in `signalforge.draft.schema`) builds `business_rules = tuple(_read_business_rules(model))` AFTER the existing `model_columns_by_type` build and threads it through `parse_draft_response(...)`. (`_read_business_rules` already exists in `prompts.py`; expose / re-import as needed.) +4. Gate logic: when `business_rules` non-empty AND `"custom_sql" not in exclude_tests`, count `custom_sql` tests across `candidate.tests` + every `column.tests` and append one violation if `count < len(business_rules)`. +5. Violation message: `Expected ≥{N} custom_sql test(s) (one per declared business rule), got {actual}. Declared rules: {comma-separated quoted rule strings with their (model)/(column X) prefixes}.` Pinned by test. +6. Gate is a no-op when `business_rules = ()` (preserves all 36 existing parser-test call sites; backward compat). +7. Gate is a no-op when `"custom_sql"` is in `exclude_tests` (DEC-008). +8. Unit tests cover: under-coverage rejection (2 rules + 1 custom_sql → violation present); coverage match (2 rules + 2 → accept); over-coverage allowed (2 rules + 3 → accept); empty rules + zero custom_sql → accept; empty rules + custom_sql present → accept (inferred-fallback path preserved); custom_sql in exclude_tests + non-empty rules → no gate violation; column-level custom_sql tests counted; model-level custom_sql tests counted; mixed counted. +9. Multi-violation collect-all preserved: a candidate with a hallucinated column AND a cardinality miss produces BOTH violations in one `LLMOutputAnchorContractError`. +10. Canonical validation command passes. + +**Done when:** the parser gate rejects an under-coverage response loudly with a verbose message, the inferred-fallback path stays open, and `tests/cli/test_e2e_business_rules.py` (the existing e2e) continues to be the live cert. + +**Files:** + +- `src/signalforge/draft/parser.py` — add kwarg + gate logic to `_validate_anchor_contract`; add kwarg to `parse_draft_response`. +- `src/signalforge/draft/schema.py` — build `business_rules` tuple from `_read_business_rules(model)`; thread through `parse_draft_response(...)`. +- `src/signalforge/draft/prompts.py` — confirm `_read_business_rules` is importable from `schema.py` (or re-export); no behavioural change. +- `tests/draft/test_parser.py` — 8+ new tests per AC #8. + +**Depends on:** US-001 (the envelope-shape change is the operator-facing half; landing the parser gate without it would surface the rejection without giving the LLM the clearer input format — together they're the complete fix). + +**TDD:** yes — write the 8 gate-behaviour tests FIRST against the unchanged parser (they should fail); implement until all pass. + +### US-003 — Quality Gate (code review x4 + CodeRabbit) + +**Traces to:** the project's standard Quality-Gate convention. + +**Description:** Run the `/code-review` skill four times across the full diff, fix every real bug found each pass.

Ask the user to run `dbt parse` themselves — this skill's `allowed-tools` deliberately does NOT include `Bash(dbt *)` so it cannot run the parse for them. `dbt parse` requires a configured dbt profile (`~/.dbt/profiles.yml`) and does NOT hit the warehouse, but it does need the profile to exist. If the user has no profile yet, jump to Section 2 (bundled demo) so they can try SignalForge before standing up a real warehouse. + +Once `target/manifest.json` is present, identify the model to work on.

Bundled demo + +The fastest way to see the full pipeline end-to-end is the bundled Austin bikeshare demo. It removes the dbt-project setup cost (the demo ships a frozen `manifest.json` and a ready-to-go `signalforge.yml`) but it is **not credential-free** — the demo's `generate` step actually queries the public BigQuery dataset `bigquery-public-data.austin_bikeshare`, billed to your `GOOGLE_CLOUD_PROJECT`. Before running it, confirm: + +- `ANTHROPIC_API_KEY` is set (the drafter always calls Anthropic; free tier covers the demo). +- `GOOGLE_CLOUD_PROJECT` is exported to your own GCP billing project. +- ADC are configured: `gcloud auth application-default login`. + +If any of those are missing, fall back to the truly offline path: `signalforge lint --model ` reads only the manifest (no LLM, no warehouse) and surfaces shape issues. Use it to demonstrate manifest-shape diagnostics without spend. + +```bash +signalforge init-demo +``` + +That writes a self-contained dbt project into `./signalforge-demo/` by default. Pass a path to override (`signalforge init-demo /tmp/sf-demo`). Then: + +```bash +cd signalforge-demo +signalforge generate models/staging/stg_bikeshare_trips.sql --write +``` + +`--write` materialises the proposed `schema.yml` + any singular `tests/*.sql` files into the project. Without `--write`, `generate` prints the diff to stdout and exits — read-only is the safe default. + +SignalForge defaults to `safety: schema-only` — only column **names** and **types** leave the warehouse / fixture. No row values, no aggregates. The demo runs under that posture; nothing sensitive can leak. + +Read the printed diff. You should see: + +- A **kept** column-test table (every test SignalForge believes adds signal). +- A **kept-uncertain** column (tests SignalForge couldn't positively evaluate — shipped under the conservative-bias contract). +- A **dropped** column with the always-pass reasons (`always-passes`, `failed-on-known-clean-data`, `requires-future-data`). +- A unified diff against the (initially empty) existing `schema.yml`. + +Every row in every column has a one-line "why" — read these before deciding whether to keep the run. + +## 3. Real project: draft + prune + +For a user's own dbt project, the command shape is the same: + +```bash +signalforge generate --write +``` + +Where `` is a file path or unique_id from Section 1. The safety posture matters: + +- **Default** is `safety: schema-only` — schema-only is the deployment-blocker safe default. The LLM sees column names + types only. +- **Opt-in** `--mode sample` ships a small warehouse sample to the LLM. This has both **cost** (warehouse query + larger LLM prompt) and **privacy** (real row values leave the warehouse) implications. Use it only when the LLM's schema-only output is missing context the operator needs. +- **Opt-in** `--mode aggregate-only` ships per-column aggregates (count, distinct, null-rate) without raw rows. Middle-ground. + +`signalforge version` verifies the install resolved before you spend warehouse / API budget. `signalforge generate --estimate` previews the LLM + warehouse byte cost without firing real calls. + +The `.signalforge/` directory under the project carries durable audit JSONLs for every stage (safety, llm_responses, prune, grade) plus per-run sidecars (`grade.json`, `diff.json`). These are append-only; they survive crashes mid-run. + +## 4. Grade tests you already have + +If the user has **existing dbt tests** authored by dbt-codegen, dbt Copilot, DinoAI, or a human, SignalForge can grade them without re-drafting. This path makes **no LLM call** — it runs the ingest → prune → diff pipeline against externally-authored `schema.yml`: + +```bash +signalforge prune-existing --schema +``` + +Where `` is the `schema.yml` file containing the existing tests. The command is **read-only** — there's no `--write` flag, because the source `schema.yml` is hand-authored and overwriting it would be surprising. The diff shows what to **remove** from the file (always-pass tests, failed-on-known-clean tests). Apply the diff by hand, or pipe it through your usual review process. + +The same scope / sample-strategy flags from `generate` apply (`--scope`, `--sample-strategy`). The `--mode` flag is inert here — `prune-existing` never builds an LLM payload, so the safety policy has nothing to shape. + +## 5. Reading the diff + +Every kept / kept-uncertain / dropped / flagged row carries a one-line "why." The four tiers: + +| Tier | Meaning | Ships in `schema.yml`? | +|---|---|---| +| **kept** | Test ran with positive evidence — caught a real failing row on warehouse samples, OR grader passed. | Yes | +| **kept-uncertain** | Test could not be positively evaluated (budget elapsed, identifier rejected, materialisation failed, prune disabled).

Optional: live e2e demonstration + +The repo ships a live end-to-end test that exercises the full pipeline against real BigQuery + real Anthropic. **It is gated for a reason** — it costs real money and real API quota. Before invoking it, you MUST: + +1. **Confirm with the user, verbatim:** + + > **This will run paid LLM + warehouse queries — proceed?** + + If the user does not say yes, STOP. Do not run the test. + +2. **Check the required env vars.** All three must be set: + + ```bash + echo "SF_RUN_BQ=${SF_RUN_BQ:-}" + echo "GOOGLE_CLOUD_PROJECT=${GOOGLE_CLOUD_PROJECT:-}" + echo "ANTHROPIC_API_KEY=${ANTHROPIC_API_KEY:+}" + ``` + + If any is unset, **clean-skip with a clear reason** — name the missing var, do NOT run the test. Example: "Skipping live e2e: `SF_RUN_BQ` is unset (need `SF_RUN_BQ=1`)." + +3. **Surface the cost expectation.** The current live e2e costs on the order of a few cents per run (small Austin bikeshare model + one Anthropic Sonnet draft + one grade pass). Cost detail and tuning notes live in `docs/e2e-smoke-test.md` — point the user at that file before running. + +4. **Only THEN run the test:** + + ```bash + uv run pytest -m e2e --no-cov + ``` + + `--no-cov` is required — coverage's `--cov-fail-under` would fail a marker-specific run that exercises only a fraction of the codebase. + +Surface the test output verbatim.

Troubleshooting + +Common errors and their one-line fixes: + +- **`ModelNotFoundError`** — the model arg did not resolve. Verify with `signalforge lint --model ` (accepts bare names + disambiguates collisions across packages). For `generate` / `prune-existing`, use the file path (`models/staging/stg_orders.sql`) or unique_id (`model..`) form. Tier-2 exit code. +- **`WarehouseAuthError`** — adapter could not authenticate. Check `~/.dbt/profiles.yml` is configured for the target profile + that ambient credentials (gcloud ADC, service-account JSON) are valid. Tier-3 exit code (external dependency). +- **`LLMCacheTooLargeError`** — the cached prompt block (model under draft + its direct refs / depends_on neighbours) exceeded 8000 input tokens. Narrow the surface: either trim the model's manifest scope (smaller graph) or split the model into smaller models. Tier-2 exit code (input validation — pre-LLM-call payload-size check). +- **`PromptEnvelopeBreachError`** — drafted SQL or `meta.signalforge.business_rules` content contains the literal closing-tag fence (`` or ``). Remove or rephrase the offending content. Tier-2 exit code. +- **`SamplingRequiresPartitionFilterError`** — model is large (>= 100M rows) and no partition filter was supplied. Either configure `prune.partition_filter` in `signalforge.yml`, or scope to a smaller model. + +Exit codes follow the four-tier taxonomy: **0** success; **1** load / parse failure (manifest missing, config malformed); **2** input validation (bad model id, anchor-contract violation); **3** external dependency (warehouse, LLM, audit-write durability). No traceback ever leaks — every CLI handler wraps its pipeline in one boundary catch. + +For the full flag reference, exit-code table, and per-stage operational detail, point the user at `docs/cli-ops.md`.
