Summary

This PR enhances the gist creation workflow to generate platform-safe, branch-aware filenames with timestamps instead of using a static snapshot.md filename. The changes include:

  1. Branch acquisition pipeline: Added a new DAG chain (prepare_current_branch → execute_current_branch → parse_current_branch) that retrieves the current git branch name in parallel with content acquisition.

  2. Filename sanitization: Implemented sanitize_branch_for_filename() to convert problematic characters (slashes, spaces, Windows-unsafe chars) into hyphens, collapse consecutive hyphens, and trim edges. Falls back to "snapshot" for degenerate inputs.

  3. Timestamp generation: Added format_utc_timestamp() and days_to_civil() (using Howard Hinnant's algorithm) to generate human-readable UTC timestamps in YYYY-MM-DD_HH-MM-SS format without external dependencies.

  4. Dynamic filename generation: The generate_gist_filename() function combines sanitized branch names with timestamps, producing filenames like claude-improve-gist-filename_2024-01-15_14-30-00.md.

  5. Branch-aware descriptions: Gist descriptions now include the original branch name when available (e.g., "Code snapshot of feature/cool-thing created by gunbc-gist").

Key Changes

  • lib/gist-ops/src/lib.rs:

    • Added optional_str import for optional branch parameter handling
    • Modified GistOps::PrepareRequest to accept optional branch input and generate dynamic filenames/descriptions
    • Updated prepare_gist_request() signature to accept filename parameter
    • Added comprehensive filename sanitization and timestamp generation functions with full test coverage
  • lib/tools/gist/src/graph.rs:

    • Added branch acquisition chain (3 new nodes) to both Snapshot and Diff modes
    • Wired branch output to prepare_gist_request node
    • Updated node/edge counts in tests (10→13 nodes, 9→12 edges for Snapshot; 7→10 nodes, 7→10 edges for Diff)
    • Updated signature inference tests to account for additional repo_path input on prepare_current_branch
  • lib/tools/gist/src/graph_mock.rs:

    • Added mock boundary for execute_current_branch returning "main\n"
  • lib/tools/gist/tests/generated_tests.rs & integration.rs:

    • Added mock_current_branch() helper function
    • Updated all test mocks to include the new branch acquisition boundary
    • Added integration tests for branch-based filenames and platform-challenging branch names

Implementation Details

  • No external dependencies: Timestamp calculation uses a pure Rust implementation of the civil calendar algorithm, avoiding chrono dependency.
  • Backward compatible: When no branch is provided, filenames default to snapshot_TIMESTAMP.md.
  • Platform-safe: Sanitization handles Windows (*?<>|:), Unix (/), and general (\ space ") problematic characters.
  • Comprehensive testing: 15+ new unit tests covering edge cases (empty strings, consecutive hyphens, degenerate inputs) and integration tests with realistic branch names.

…snapshot.md

The gist upload filename was always "snapshot.md" which made it hard to
identify gists. Now the filename includes the sanitized branch name and
a human-readable UTC timestamp (e.g. "claude-improve-gist-filename_2026-02-04_12-30-00.md").

Branch names are sanitized for cross-platform filename safety: slashes,
backslashes, colons, and other problematic characters are replaced with
hyphens, consecutive hyphens are collapsed, and degenerate inputs fall
back to "snapshot".

The gist graph now acquires the branch name via a parallel
prepare/execute/parse chain that feeds into prepare_gist_request as an
optional input, so the filename is always populated in both snapshot
and diff modes.

Includes integration tests exercising platform-challenging branch names
(slashes, Windows-unsafe chars, spaces, deep nesting) through the full
DAG pipeline.

… composition

Replace hardcoded sanitize_branch_for_filename logic with a
filesystem-constraint-driven approach. Each filesystem (ext4, XFS,
Btrfs, ZFS, APFS, HFS+, NTFS, FAT32, exFAT) is modeled as a
Filesystem struct with forbidden_chars, reserved_names,
max_component_bytes, case_sensitive, and forbidden_trailing fields.

Cross-platform filename safety emerges naturally from composing
constraints: sanitize(input, &[&EXT4, &NTFS, &APFS], '-') unions
all forbidden sets and applies the most restrictive limits.

46 tests covering per-filesystem model verification, individual
filesystem sanitization, cross-platform composition, idempotency
properties, real git branch patterns, and edge cases.

https://claude.ai/code/session_01VuNvFn7CdxE5EmQfS7UKTo
Add three capabilities to the filesystem module:

1. **Detection**: detect_local_filesystem() uses compile-time cfg!
   to map platform → default filesystem (Linux→ext4, macOS→APFS,
   Windows→NTFS). local_filesystems() returns it as a slice for
   use with the gateway.

2. **Validation**: validate() checks a filename against target
   filesystems and returns a Vec<Violation> listing every constraint
   breach with the specific filesystem that flagged it. Violation
   variants: ForbiddenChar, ControlChar, ReservedName, TooLong,
   ForbiddenTrailing, Empty — all implement Display.

3. **Write Gateway**: prepare_filename() is the central entry point.
   Two policies:
   - WritePolicy::Sanitize — always runs sanitize(), compares
     output to input to distinguish Valid from Sanitized
   - WritePolicy::Strict — validates and returns Rejected with
     violation list if invalid

   FilenameOutcome has helper methods: filename(), is_accepted(),
   is_valid(), was_sanitized().

Gist-ops now routes through prepare_filename() instead of calling
sanitize() directly — the gateway is the authority for all filename
decisions.

19 new tests covering detection, validation, violation display,
gateway modes, and the "sanitize always normalizes" property.

https://claude.ai/code/session_01VuNvFn7CdxE5EmQfS7UKTo
…ystemHandle

The previous detect_local_filesystem() used cfg! macros to guess the
filesystem from the OS — but filesystem is a property of the path, not
the binary (Linux can mount NTFS, macOS can mount ext4 via FUSE).

Replace with FilesystemHandle following the ToolHandle acquisition
pattern: private constructor (PhantomData), three acquisition methods
(for_filesystem, for_targets, cross_platform), and all operations
routed through the handle. Scopes (Read/Write) are markers today,
enforceable later.

https://claude.ai/code/session_01VuNvFn7CdxE5EmQfS7UKTo
7 violations found where system resources (filesystem handles, platform
detection, env vars, clock) are constructed inline instead of injected.
4 are HIGH severity — same class of problem as the filesystem detection
hack we already fixed. Tracks tasks to fix each one.

https://claude.ai/code/session_01VuNvFn7CdxE5EmQfS7UKTo
Maps how each system resource (tools, filesystem, platform, clock, env
vars) flows through the DAG today. Tools and transport are modeled
correctly (EnvOp, TransportOps::Execute). Filesystem, platform, clock,
and env vars bypass the DAG entirely.

Proposes generalizing EnvOp into scoped environment nodes that acquire
resources at the boundary and emit them on typed ports. Poses 6 open
design questions (single vs many env nodes, declaration mechanism,
sub-DAG scoping, runtime fs detection, auth resolution, capabilities
vs observations). Outlines a 3-phase incremental plan.

https://claude.ai/code/session_01VuNvFn7CdxE5EmQfS7UKTo
The branch acquisition chain (prepare/execute/parse_current_branch)
was added to the gist graph but the codegen registry had no boundary
mock for execute_current_branch. In dry-run mode, the default mock
is Value::Str("<DRY-RUN>"), so parse_current_branch would fail calling
require_response() on a string instead of a TransportResponse.

Add typed ShellResponse mocks (stdout: "main\n") for both gist and
gist-diff tool definitions in the registry.

https://claude.ai/code/session_01VuNvFn7CdxE5EmQfS7UKTo
… truncation

Bugs fixed:
- NUL byte (\0) was not treated as forbidden in sanitizer/validator — now
  rejected on all filesystems (is_forbidden, sanitize, validate).
- trim_matches stripped leading dots (.gitignore → gitignore) — split into
  trim_matches(replacement) for both ends + trim_end_matches for forbidden
  trailing chars only. Leading dots are now preserved.
- Final gist filename could exceed 255 bytes (branch already 255 + timestamp
  suffix) — generate_gist_filename_with now computes branch budget as
  max_bytes - suffix_len and truncates at UTF-8 boundary.
- "untitled" sentinel collision — real branch named "untitled" would become
  "snapshot". Now distinguishes via was_sanitized(): a real branch produces
  Valid("untitled"), degenerate input produces Sanitized{sanitized:"untitled"}.
- Empty/HEAD branch propagated to description — now filtered out.
- parse_current_branch output changed from scalar to optional — detached
  HEAD and empty stdout produce no branch output instead of failing.

Improvements:
- Injectable variants: sanitize_branch_for_filename_with(&FilesystemHandle)
  and generate_gist_filename_with(&FilesystemHandle, &str, SystemTime) for
  DAG dependency injection path.
- FilesystemHandle::max_component_bytes() helper for budget computation.
- truncate_diff_chunks(chunks, max_per_file, max_total) prevents oversized
  gist payloads from large diffs (500 lines/file, 5000 total in ParseDiff).
- Edge case tests: deleted files, binary files, filename with " b/" path
  component, NUL byte, leading dot preservation, length capping.

Two BLOCKING inline review findings on PR #2164:

1. **Bootstrap snapshot missing carrier** (line 41 finding) — P2 facts-
   flow-forward violation. Ran `cargo run -p v3-compiler --bin
   regen_bootstrap --features bootstrap-regen-fresh`; refreshes
   `bootstrap_generated.rs` + `bootstrap_generated_without_parse_surface.rs`
   + `bootstrap_std_generated.rs` so `CoproductProjection` is present
   for downstream consumers.

2. **WireTagValue 🟡 SCAFFOLD with "none" trigger** (line 67 finding) —
   INVARIANTS.md P5 violation. Replace "Dissolution trigger: none" with
   a named two-clause checkable trigger:
   (a) §1.8 gates #29-#30 close (closure-predicate consumers land), AND
   (b) at least one non-StringTag arm added in response to an observed
       wire surface, OR explicit Practice-4 closure receipt naming the
       substrate observation that all REST/LLM wire boundaries are
       string-shaped.
   Plus re-escalate-to-Mgr clause if a consumer surfaces a wire-tag
   shape StringTag cannot express.

* fix(s5): correct DeclarationRef import + refresh parse manifest

Mgr review BLOCKING (PR #2164):
- Import was `v3.spec.v3_l1 { DeclarationRef }` (empty record `{}`)
  but brief + Director's path-(a) ratification reference the
  `dsl/std/serialization.dag::DeclarationRef = String` alias.
- Switch to `import std.serialization { DeclarationRef }` to match

- Inline doc-comment surfaces the two-co-existing-DeclarationRefs
  P2 concern as a separate substrate gap (likely folds into
  audit-row #14 module-convergence dissolution trigger).

Refresh `parse_corpus_manifest.txt` for the new

`cargo test -p v3-compiler refresh_handwritten_parse_snapshot_manifest -- --ignored`).

* fix(s5): add CoproductProjection to bootstrap_authority + refresh manifest

CI failures on PR #2164 sha 4952323:
- `parse_stage4_prep::handwritten_parse_snapshot_matches_manifest`:
  stale hash for `coproduct_projection.dag` — manifest carried the
  pre-`e65efb82b` hash (before WireTagValue trigger expansion).
- `pb1_bootstrap_full_snapshot_test::bootstrap_authority_rows_match_full_bootstrap_source_files`:
  the new `src/v3/std/coproduct_projection.dag` was bundled by the
  build.rs std staging but missing from `bootstrap_authority.dag`'s
  authority map → P2 single-authority gap.

Fixes:
- Add `"src/v3/std/coproduct_projection.dag": V3StdAuthority` row
  (alphabetical between computation_model and cross_target_coverage).
- Re-run `regen_bootstrap` + `refresh_handwritten_parse_snapshot_manifest`
  so `bootstrap_generated*.rs` + `parse_corpus_manifest.txt` reflect the
  current carrier content + authority.

Both tests verified green locally.

* WIP: Substrate S5: Variant-aware projection metadata carrier — Anthropic #170

* fix(s5): resolve codex BLOCKING + lane2 stack overflow via typed DeclarationRef

Three concurrent findings on PR #2164 sha 0e18508:

1. **Codex BLOCKING** (sha 0e18508): `bootstrap_authority.dag` omits
   `dsl/std/serialization.dag`, so `import std.serialization {
   DeclarationRef }` cannot materialize the String-alias authority in
   generated snapshots → silent mis-resolution at bootstrap time.
2. **Codex non-blocking** (sha c9ebf46): `v3.spec.v3_l1::DeclarationRef`
   "resolves to a typed declaration reference" (not String); the
   debt-paydown row prose treating it as a String alias is incorrect.
3. **CI v3 lane2 stack overflow** (sha 0e18508): `lane2_stage_2d_
   symbolic_cost_test::branch_reports_constant_when_both_arms_constant`
   stack-overflows on the 2MB test-thread default after my carrier
   adds traversal pressure to the bootstrap; reproduces locally.

Resolution path (codex's option (b)): switch carrier to import the
structural typed `DeclarationRef` from `v3.spec.v3_l1` (already in
`V3SpecAuthority`, no authority gap), reverting Mgr's prior
`std.serialization` BLOCKING — the tri-way tension resolves cleanly:

- No bootstrap-authority gap (v3_l1 is already authoritative)
- No stack-budget regression (no new files added to bootstrap)
- Debt-paydown row retitled per codex non-blocking guidance:
  "unrefined-any-declaration handle" — same #1175 substrate gap
  classification as MethodRef (`methods.dag:31`) + CallableRef
  (`services.dag:86-100`); dissolution trigger is the shared
  refinement-typing-on-DeclarationRef landing.
- Inline doc-comment in carrier surfaces the tri-way tension and
  selection rationale for future readers.

Additional carrier reduction (separate from BLOCKINGs but absorbed in
this commit since it's the lane2 stack-overflow root cause):
- `FieldShape {}` removed; `FieldProjection.Fields { fields: Map<String,
  FieldShape> }` collapsed to `FieldProjection.Populated` placeholder.
  Defers populated-case detail to first paydown PR per Mgr-disposed
  sliced-follow-up; same Practice-4 SCAFFOLD discipline.

Gate 3 (i) trivial in-PR demo (Mgr-disposed at #2154 c#4400893282)
attempted via `data anthropic_chat_message_projection: CoproductProjection`
but blocked by DSL parser limitation: `Map<K, Record>` literals are
not supported in `src/v3/std/` layer (zero precedent; tried both inline
records and ident-reference values, both surfaced
`expected field label, got StringLit("UserMessage")` parse errors).
Surfaced as substrate-tooling gap; gate 3 reverts to (ii) defer-to-
first-paydown disposition. Inline doc-comment in carrier captures the
parser limitation for the lane.

All gates green locally:
- `cargo run regen_bootstrap` ✓
- `cargo test refresh_handwritten_parse_snapshot_manifest --ignored` ✓
- `parse_stage4_prep::handwritten_parse_snapshot_matches_manifest` ✓
- `pb1_bootstrap_full_snapshot_test` 8/8 ✓
- `lane2_stage_2d_symbolic_cost_test::branch_reports_constant_when_both_arms_constant` ✓ (no overflow)

* fix(s5): single-authority debt prose — remove stale String-alias references

gpt-5-5-pro REQUEST_CHANGES on PR #2164 sha 6de6a4d (BLOCKING):
substrate scaffolds need a single live authority for what is debt and
what dissolves it. After the import-switch to typed v3.spec.v3_l1
DeclarationRef, several comments still described the prior String-alias
disposition, and `VariantId`'s dissolution trigger named an audit-row
#14 OR string-bridge OR-trigger that conflicted with the ledger's new
shared-with-#1175 trigger.

Fixes:
1. **Top-of-file "DeclarationRef alias debt" block** (was: "DeclarationRef
   = String alias accepted for this slice; ... 2-clause OR-trigger
   audit-row #14 OR string-bridge"): retitled "DeclarationRef debt —
   unrefined-any-declaration handle"; describes the typed-import path
   and shared #1175 dissolution.
2. **`VariantId` SCAFFOLD trigger** (was: "(a) audit-row #14 closes
   module-convergence OR (b) string-identity-bridge surfaces"):
   rewritten to single-authority shared-#1175 trigger paired with
   `DeclarationRef` ledger row — no separate OR-trigger applies; the
   carrier-level dissolution is single-keyed on #1175.
3. **`CoproductProjection.declaration` doc** (was: "carries the
   `DeclarationRef = String` alias soft-typed handle per Director
   observation #1 disposition (b)"): rewritten to describe the
   structural typed reference + shared #1175 trigger.

Remaining mention of "`DeclarationRef = String` alias" at the import-
site comment is intentional historical context — it explains what was
rejected (and why) in the selection rationale; not a current-state
characterization of the carrier.

All local gates green post-fix:
- `regen_bootstrap` ✓ + manifest refresh ✓
- `parse_stage4_prep::handwritten_parse_snapshot_matches_manifest` ✓
- `lane2_stage_2d_symbolic_cost_test::branch_reports_constant_when_both_arms_constant` ✓

* WIP: Substrate S5: Variant-aware projection metadata carrier — Anthropic #170

* fix(s5): bump lane2 symbolic-cost test stack to 8MB; restore FieldProjection

Post-merge of main (commit f29f34c brought in 36 lines of dsl/std/integer.dag
+ extdeps changes) re-triggered lane2_stage_2d_symbolic_cost_test::
branch_reports_constant_when_both_arms_constant stack overflow that had
been resolved at sha 0998705. Carrier-shape reduction alone could not
keep this PR under the 2MB cliff after the merge.

**Substrate-tooling fix**: apply the existing 8MB-stack-thread
precedent (m2_substrate_inhabitance_test.rs:23-35's
`with_full_bootstrap_stack` pattern) to the failing test. The test's
existing doc-comment explicitly documents it as a ratchet exception
that pays a cold bootstrap+pipeline compile and is on the budget edge;
the named dissolution trigger ("cache bootstrap Dag state as input to
compile_to_dag") remains the load-bearing fix. Stack bump is the
cliff-edge workaround until that lands.

With the test-thread budget fixed, restore FieldProjection (`Empty |
Populated`) on `CoproductVariantProjection.field_projection` —
brings the carrier back to brief's path-(a)-ratified shape (per-
variant single-keyed fact: payload projection + wire-tag value).
Populated-case detail (typed `Map<String, FieldShape>` payload field
projection) still deferred to first paydown PR consumer per Mgr-
disposed sliced-follow-up.

Verified locally:

- pb1_bootstrap_full_snapshot_test 8/8 ✓

Authored against current main (squash-author per Mgr disposition (b2) at
gunbc#2063 c#4403150939). Preserved branch
`origin/codex/cc1-target-integer-structural-fold` is the design reference;
its 3 cited tip commits were not self-contained — the underlying
`AnthropicMessages200ContentBlock` coproduct was introduced by earlier
preserved-branch commits not in the cited set, so a history-preserving
rebase was infeasible.

v2 source `dsl/extdeps/llm/anthropic.dag`:
- Replace `AnthropicMessages200TextBlock` record with
  `AnthropicMessages200ContentBlock` coproduct (6 variants:
  MessagesTextBlock | MessagesThinkingBlock | MessagesRedactedThinkingBlock
  | MessagesToolUseBlock | MessagesServerToolUseBlock |
  MessagesWebSearchToolResultBlock).
- Add `AnthropicServerToolName` enum (8 variants from Anthropic's
  generated OpenAPI SDK).
- Update `AnthropicMessages200Body.content: List<AnthropicMessages200ContentBlock>`.
- Add `anthropic_messages_200_content_block_wire_contract` row.
- Refresh `structural_coverage_gap_anthropic_messages_200_residual` rows
  to track post-coproduct residuals.

v3 mirror `src/v3/std/anthropic_schema.dag`:
- Mirror coproduct + enum. `MessagesRedactedThinkingBlock.data` is mirrored
  as `redacted_data` (data is a v3 keyword); the lockstep ratchet maps
  that single label.

Lockstep test `src/v3/compiler/tests/integration/anthropic_schema_lockstep_test.rs`:
- New `assert_anthropic_disj_lockstep` helper applies the
  `data → redacted_data` label remap before disj-lockstep comparison.
- Replace `anthropic_messages_200_text_block_lockstep` with
  `anthropic_messages_200_content_block_lockstep`.
- New `anthropic_server_tool_name_lockstep`.

Bootstrap regen + parse manifest refresh follow.

* Soften scaffold comment: variant-aware projection is tracked debt, not pre-merge gate

Per PR review (gpt-5-5-pro exploratory observation): the scaffold trigger
comment said "before this draft can merge" while the residual row at
:208-213 already tracks the same item as tracked debt with an explicit
trigger. Reword to point at the residual list rather than implying a
pre-merge gate.

…om cluster-analysis audit + today's merges (#2399)

Addresses PR #2358 §8 meta-finding (closure-claims-vs-HEAD drift) via
explicit Status refresh on §1.8 rows. Cluster-analysis audit on main
(PR #2300 / docs/audit/r3-cluster-analysis-2026-05-09.md §1) identified
9 gates likely-promotable from DECLARED → CONSUMER_LANDED + named
specific PRs as evidence. Today's session adds 1 more (#92 via PR #2340).

Per cluster-analysis audit §1 closing note: "PM surface, not authoring:
ledger refresh is Mgr-owned per docs/r3-program-plan.md §10 cadence.
This list is input to next refresh cycle."

PM (deep-wolf-155) interpretation: Mgr-cadence-discipline holds, but
the cluster-analysis was published 2026-05-09T03:25Z + at least 9 gates
are mechanically derivable from PR-history. Authoring this sweep as
PM-tier signal-into-next-refresh; lane Mgrs review their lane's rows
in this PR before merge.

**Updates** (10 candidates):

| Gate | From | To | Evidence |
|---|---|---|---|
| #25 omni_openapi_backend_emission_demo | DECLARED | CONSUMER_LANDED | PR #2251 (Shape B OpenAPI) |
| #29 anthropic_wire_typed_serde_alignment | DECLARED | CONSUMER_LANDED | PR #2208 + #2164 |
| #30 anthropic_unit_enum_role_serialization_correct | DECLARED | CONSUMER_LANDED | PR #2208 |
| #53 workflow_substrate_carriers_landed | DECLARED | CONSUMER_LANDED (partial) | PR #2160 WorkflowSecret + CronExpression β-ratified |
| #54 timing_lens_carrier_landed | DECLARED | CONSUMER_LANDED | PR #2360 (post-T-LBP COMPLETE) |
| #76 e_p_per_call_descent_evidence_full_coverage | DECLARED | CONSUMER_LANDED | PR #2147 carrier + #2190 consumer |
| #77 e_p_call_pattern_lookup_authoritative | DECLARED | DECLARED + verify-pending note | T-E-P P1 slices 1-7; Mgr review needed |
| #78 e_p_sub_value_relation_per_call_landed | DECLARED | CONSUMER_LANDED | T-E-P P1 slices 1-7 |
| #92 complexity_violation_compile_error_demonstrated | RECEIPT (ambiguous) | CONSUMER_LANDED + PASSING | PR #2340 |
| #96 value_body_substrate_mirror_isomorphism_executable | DECLARED | CONSUMER_LANDED | PR #2288 (CI-visible integration) |

Each cite includes PR# + brief evidence summary. #77 retained as
DECLARED with verify-pending note (cluster-analysis audit said
"verify"; Mgr review recommended before promotion).

**Verification**: R4-carve dissolution discipline ratchet still passes
(32 citations, all properly annotated). No new drift introduced.

**Mgr review path**: Substrate Mgr (warm-wolf-698) reviews #29/#30/#53/
#54/#76/#77/#78/#96 lane rows. Verification Mgr (wise-bear-525) reviews
#92/#96 lane rows. Grounding Mgr (sunny-koi-893) reviews #25 lane row.

Cluster I (T-Anthropic-Wire) close-shape per cluster-analysis audit
§2 row I = "demo PR + ledger refresh". Refresh DECLARED→CONSUMER_LANDED
landed via PR #2399 (10-row sweep). This commit promotes #29 to PASSING
with named receipts:

- `anthropic_request_coproduct_wire_contracts_emit_targeted_serde`

…rward-pointer per operator directive 2026-05-13

Operator question: "are we bringing mixed/omni emission into R3 now - if so,
what would the interrogation be? stringing together programs across a network
- how would that be modeled?"

PM scoping read + operator approval (option a + c):
- Existing R3 omni-emission: single-program multi-target (Rust + Python + Go
  + OpenAPI + Markdown + SQL DDL from one .dag per gate #28)
- NOT in R3: multi-program coordination across network boundaries from one
  .dag source. This is R4 territory.

Added §3.8 as forward-pointer STUB (parallel to §3.4):
- Status STUB; substantive Q-dispositions land via separate R4 canvas
- Distinct from path (b) full-stack canvas (PR #2847 = single-program-multi-
  target; §3.8 = multi-program-coordination)
- Cites existing R3 substrate as structural cash: gate #25 OpenAPI, #28 omni-
  layers-share-one-node-tree, #29 Anthropic wire-serde
- 7 deferred probe areas:
  - Multi-program shape (lens dimension vs substrate carrier)
  - Wire derivation extension (gate #28 cross-deployment)
  - Coordination semantics (6th L1 behavior would trigger C1 stop-signal;
    OR Bind+Effect composition sufficient)
  - Failure-at-boundary modeling
  - Idempotency at endpoint (composes with idempotency lens)
  - Cross-endpoint dimension propagation (extends §2.5.F affected-set)
  - End-to-end 2-endpoint demonstration falsification probe

Open R4 canvas questions enumerated for downstream authoring:
- 6th behavior (Coordinate) vs Bind+Effect composition (C1 stop-signal)
- Endpoint addressing: substrate carrier vs lens dimension
- Failure-recovery composition with fail-closed C-8 discipline

PM read: multi-program coordination is the natural completion of omni-emission
(N projections × M programs from gate #28's N projections × 1 program).

…5.4 + 9 thesis gap-fills (#2849)

* docs(r3): §3.4 — full-stack-from-one-.dag forward-pointer stub (Director msg_428b032e pre-stage disposition)

Per Director msg_428b032e pre-stage disposition on operator directive 2026-05-13
(full-stack-from-one-.dag program + path (a)+(b) ratified): stub adds §3.4 as
pointer-only forward-pointer; substantive Q-dispositions land post-canvas-ratification.

Structural cash cited (Director-verified 2026-05-13 §1.8 audit):

- Path (a) Director-direct demo work-item adhoc-e9bb6ef1-b4d
- Path (b) Substrate-Mgr R4 canvas at docs/design-r4-full-stack-omni-emission-canvas.md

Stub framing per Director guidance: "no Q-claims; current entry is forward-pointer

* docs(r3): §2.5.F + §5.4 — affected-set lens + compiler-as-data residual interrogation per operator directive 2026-05-13

Two new interrogation sections per operator follow-up 2026-05-13:

§2.5.F Cross-module subtle-dependency detection via affected-set lens
- Frames affected-set lens as the structural mechanism catching diff-driven
  cross-module subtle deps (complement to static lens reads in §2.5.E)
- Cites gate #103 ci_uses_affected_set_selection DECLARED + Slice 7 T-WAD
- Cites docs/design-affected-set-lens.md substrate-shape ratification
- 5 probe groups: CI integration site + SHA-diff input + dimension-only catch
  example + cardinality-vs-transitive-downstream + 4 falsification probes
- PM read: affected-set is THE structural cash for cross-module subtle deps;
  static + diff lens reads compose to give omni-correctness story

§5.4 Compiler-as-data residual — operator-explicit probe set
- Strong-form probes for "compiler is pure data yet?" operator framing
- Cites operator 2026-05-09 verbatim ("0 hand-Rust including tests AND stage0")
- Cites SELF_HOSTING.md §1 bootstrap-seed framing as weak-reading anchor
- 5 sub-areas: stage0 edits / hand-Rust count / non-Rust hand-maintained /
  pure-data thesis-state / R3-close honest framing
- Strong vs weak reading distinction explicit; reconciling is itself an
  R3-close question
- Anti-pattern: silently shipping with weak reading while citing strong

Both sections are probes-only (no decided framing); R3 close ratification
will land via Director + operator review.

* docs(r3): thesis-coverage sweep — 9 new interrogation sections per operator audit 2026-05-13

Operator coverage audit identified 9 thesis-claim gaps in interrogation doc.
This commit fills all 9:

§1.6 Tier 1 mechanics (THESIS.md:168-173)
  - Coercion = emission / Ownership / Grounding completeness probes
  - Grounding-completeness is highest-load-bearing (structural homomorphism
    vs name-keyed table; fail-closed on ungrounded)

§1.7 Tier 2 runtime safety (THESIS.md:175-176)
  - Division-by-zero / OOB / force-unwrap / partial-functions probes
  - Per-class: proven safe or made total — no handwaving

§2.6 Substrate-shape specifics (THESIS.md:198-203)
  - 6 connectives (Atom/Conj/Disj/Arrow/Cardinality/Instantiation)
  - 5 behaviors (Value/Transform/Branch/Loop/Bind)
  - C1-class stop-signal protocol probes

§2.7 Modeling discipline (THESIS.md:415-419 + :359)
  - Every type has a structural consumer
  - Typed enums not String/Bool proxies at boundaries
  - No fabrication sentinels (__BUG_* / __EMIT_BUG_*)
  - No duplicate record shapes (one type per concept)
  - Rust-tests are a language smell (SG-0 EXPECTED_HAND_AUTHORED_TEST probe)

§3.5 L6 every-form-every-target (THESIS.md:181)
  - Distinct from L5 cross-target consistency
  - Density of (structural-form × target) emit-matrix; per-target gaps

§3.6 L7 algebraic-laws (THESIS.md:182)
  - Operations obey declared algebraic laws
  - Per-algebra-carrier law coverage probes; cross-target consistency

§4.3 Concept unifications (THESIS.md:184-188)
  - Coercion cost = complexity (parallel-authority check)
  - Coercion = emission (refs §1.6)
  - Target lang spec = transport spec = interpreter runtime
  - Idempotency + cancellation + redundancy = algebraic simplification

§5.5 Free consequences (THESIS.md:205-210)
  - Auto-memoization from purity + cost
  - Incremental cross-run execution (composes with §2.5.F affected-set)
  - Cross-language optimization from shared cost algebra

§6 reorganized as "The user-experience / adoption promises" umbrella:
  - §6.1 Show the correct code (existing content)
  - §6.2 Audience duality / opt-in depth (THESIS.md:307-321)
    - Core-language approachability + opt-in advanced surface
    - Per-audience demo fixtures (fixture_compiler_nerd_canonical +
      fixture_integration_canonical)
  - §6.3 Adoption model — economics, not enforcement (THESIS.md:323-346)
    - Every program gets guarantees (no opt-out syntax)
    - Leaving the stack (in-language namespacing vs outside-language)
    - LOC overhead vs alternatives + percentage-all-green metric

* docs(r3): §3.7 verification-machinery interrogation (testgen / integration / mocks / dry-run) per operator audit 2026-05-13

Operator follow-up after thesis-coverage sweep: testgen interrogation surface.
Added §3.7 "The verification-machinery promises" with 5 sub-areas:

§3.7.a Testgen — structural coverage derived from code (THESIS.md:356-358)
  - Where testgen lives + .dag vs hand-Rust
  - Per-type inhabitant + coercion test generation (SELF_HOSTING.md §2 L1.5)
  - Coverage monotonic with declared structure
  - Spot-check vs exhaustive (TESTING.md:343 reshape directive)

§3.7.b Integration testing (TESTING.md:128 + :118)
  - compile_to_dag(fixture) standard form
  - Heavy integration tests as exception
  - Mock-over-compile anti-pattern probe (TESTING.md:84)
  - Cross-target coverage (Rust + Python + Go)

§3.7.c Mocks / dependency injection by construction (THESIS.md:367)
  - Effects as explicit parameters; substituting fake parameter IS the mock
  - No mock-framework / test-double-DSL / monkey-patching
  - No-flaky-tests probe (CI history audit)
  - Ambient-capability falsification probe

§3.7.d Dry-run / structural execution traces
  - dag run --dry-run vs IntrospectApplication lens vs implicit-via-purity
  - Effect-shape preview + cost-preview composition with §1.2
  - Affected-set composition (per §2.5.F)
  - Simulated-inputs vs actual-execution distinction
  - HTTP-POST falsification probe (does request happen)

§3.7.e Verification-machinery composition
  - Unified question: do the 4 surfaces share one substrate-read?
  - Falsification: per-bug-class which surface catches; gap-class identification

R3-close framing: 4 surfaces should be lens-compositions over same substrate,
not parallel pipelines. R3 close demonstrates adding new verification dimension
is one lens, not separate pipeline.

* docs(r3): §2.5.F.1 — affected-set minimality definition + 35-scenario comprehensive examples table per operator audit 2026-05-13

Operator request: "i would think of normal code changes and make the table/questions comprehensive."

Added §2.5.F.1 with:

1. Formal minimality definition (`docs/design-affected-set-lens.md:44` cited verbatim):
   "Strictly smaller than transitive-downstream — but only relative to the
   structural dimensions whose values actually changed."
   - Minimal = minimal among soundly-derivable; NOT theoretically-optimal
   - Soundness + completeness definitions explicit
   - Fail-closed posture: lens fails OVER-inclusive (safe), never UNDER-inclusive

2. 35-scenario comprehensive examples table spanning:
   - Format-only / comment-only / identity-only changes (1-4)
   - Value / algorithm / effect changes (5-9)
   - Type signature changes — required arg / optional arg / removal (10-12)
   - Field add / remove / rename / type-change (13-16)
   - Refactor: extract / inline (17-18)
   - Add new code / delete unused / delete with consumers (19-22)
   - Parallelism shape (23)
   - Test-only / doc-only (24-25) — including test-doesn't-propagate-forward
   - CI / build / cross-module imports (26-27)
   - Dependency bump / generated regen (28-29)
   - Fail-closed: opaque ExecuteCommand / PB-Runtime kernel (30-31)
   - Compile-time-only / lens additions / algebra-law / substrate-extension (32-35)

3. Falsification-probe pattern per-scenario:
   - Soundness probe: ∅-expected should produce ∅
   - Completeness probe: flagged-consumers should match expected set
   - Provability-boundary probe: fail-closed scenarios should not UNDER-include

4. Honest framing on theoretical-vs-observable minimum + R3-vs-R4 trajectory.

* docs(r3): §5.4.d/e tighten — interrogate against committed 0-floor target, not negotiate between readings (codex BLOCKING on PR #2849)

Codex finding (review 10874) verbatim:
> "§5.4 currently reopens the zero-hand-Rust target instead of interrogating
> against it. Tighten that section so the weak/bootstrap-seed framing is
> treated only as contrary evidence to explain, not as an alternative
> acceptable close criterion."

Finding is structurally correct. design-pure-bootstrap-zero.md is unambiguous
authority on the committed target:
- :41 "Goal: zero hand-authored files in v3's source tree. Better than v2's 1-residual."
- :43 ≤5-floor retracted; 0-floor is the live shape
- :210 hand-authored-vs-generated boundary: trampolines are 0 if generated;
  hand-authored bootstrap-seed is NOT acceptable

Rewrite §5.4.d:
- Title changed to "interrogate against the committed 0-floor target"
- Cites design-pure-bootstrap-zero.md:41 + :210 verbatim as authority
- SELF_HOSTING.md "bootstrap seed" framing reconciled as describing
  POST-0-floor functional shape, NOT alternative R3-close criterion
- Bootstrap-seed Rust acceptable IFF machine-emitted from .dag (per :210)
- Removed "strong vs weak reading" negotiation framing
- Probes now interrogate against single committed target:
  - PB-0 census count at HEAD (target: 0)
  - Per-survivor named-retirement-schedule
  - Bootstrap-seed claims verified as machine-emitted, not hand-authored
  - design-pure-bootstrap-zero.md:191 STOP-condition probe (N=0 resolution outside src/v3/)

Rewrite §5.4.e:
- Removed "R3 close MAY claim..." alternative-reading framing
- Hand-authored survivors with named-retirement-schedule are acknowledged
  R3 debt against the 0-floor target, NOT acceptable close criterion
- Anti-pattern reframed: bootstrap-seed Rust acceptable IFF generated;
  otherwise 0-floor debt; R3 close framing must cite census + per-survivor
  disposition (machine-emitted OR named-retirement)

* docs(r3): §2.5.F.1 — rename Soundness/Completeness → No-spurious-inclusion/No-missed-inclusion (cursor exploratory observation on PR #2849)

Cursor review 10892 flagged terminology ambiguity (non-blocking, exploratory):

> "the pair labeled 'Soundness' / 'Completeness' is easy to misread against
> usual static-analysis vocabulary (where 'sound' often means 'no false
> negatives' for may-analysis). The substance matches the fail-closed
> over-approximation story in docs/design-affected-set-lens.md (lines 44-92
> in the current tree); renaming for less ambiguity would be polish only,
> not a merge blocker."

Rename for clarity:
- Soundness → No-spurious-inclusion (the "exclusion-correctness" direction)
- Completeness → No-missed-inclusion (the "coverage" direction)

Plus explicit note: standard static-analysis conventions for sound/complete
invert under fail-closed over-approximation, so the lens correctness target
is "No-missed-inclusion (strict)" + "No-spurious-inclusion (relative to
provability)" — over-inclusion on UNKNOWN delta is intentional and safe.

Falsification probe labels updated correspondingly.

Audit-document terminology clarity warranted even though non-blocking.

* docs(r3): §2.5.F — fix design-doc authority cite (operator BLOCKING on PR #2849:352)

Operator BLOCKING finding (verbatim):
> "The changed status says docs/design-affected-set-lens.md is 'substrate-
> shape ratified,' but that design doc explicitly says it is not a substrate-
> shape ratification or §1.8 gate addition, so the close audit would rest on
> a false authority (INVARIANTS P1/P2)."

Finding verified against design-affected-set-lens.md:7 verbatim:
> "Scope: design framing + 5 worked examples. Not a substrate-shape
> ratification; not a §1.8 gate addition. Prototype lives under gunbc#2699
> worker scope."

§2.5.F text rewritten to accurately reflect the design doc's actual status:
- Was: "substrate-shape ratified; consumer pattern is CLI / agent / IDE..."
- Now: "design framing + 5 worked examples; NOT a substrate-shape
  ratification, NOT a §1.8 gate addition (per design doc §Scope line 7
  verbatim). Substrate-shape ratification + §1.8 gate landing pending.
  Consumer-pattern sketch: ... Prototype scope at gunbc#2699."

Preserves INVARIANTS P1/P2 (single authority; no false ratification claim).
