docs(audit): T-V2 inventory follow-up — unified census + C-data split by briansrls · Pull Request #1850 · gunb-ai/gunbc

briansrls · 2026-05-06T18:30:35Z

Summary

Follow-up to merged PR #1848 addressing codex BLOCKING review at sha `3c326909` (review arrived 2 min after merge). Both findings valid:

Search authority was split — `\bv2_compiler(_tests)?\b` matches only underscored module paths and misses hyphenated Cargo dep names (`v2-compiler`). Replaced with single unified census:

```sh
grep -rEln 'src/v2/|\bv2[-_]compiler(_tests|-tests)?\b' src/ Cargo.toml dsl/
```

Surfaced one previously-missed file: `dsl/gunbc/tools/ci_runner.dag:16` (doc-comment with `cargo run -p v2-compiler` example).
`.dag` configuration-data misclassified — `dsl/gunbc/compiler.dag:53` `data compiler_source: SourceRoot = { path: "src/v2" }` is a typed value consumed by the compile pipeline, not a doc-comment. Silently rewriting it during a cosmetic G-2 sweep would either invalidate `compiler_source` or quietly retarget the compile root. Reclassified into new C-data row (§1.3 C.3) with named G-2 routing to S-1 (input-packet Decision 6 scope coverage) rather than C-cosmetic "sweep at G-2" default.

Net impact

G-1 closure surface count: still 4 (unchanged).
Population C cosmetic count: 10 → 11 (added `ci_runner.dag`).
Population C-data: new sub-class, 1 entry (`compiler.dag:53`).
Search command: split → unified single-grep.

Constraints honored

✅ No `src/v2/` deletion
✅ No Cargo edge removal
✅ No code touched
✅ No disposition decided (compiler.dag:53 routing is explicitly flagged for S-1, not chosen here)

Test plan

Unified grep command runs cleanly on current tree
Surfaces all previously-enumerated rows + the missed `ci_runner.dag:16`
Cargo dep edges (`v2-compiler` / `v2-compiler-tests`) now caught by single command

Follow-on to 23274a5 — completes the PB-owned `r3-pb-*.md` sweep. File: docs/briefs/r3-pb-regen-lens-consumer-audit.md (4 cells across "Documentation surface (authority chain)" and "Handoff points" tables; ~14 individual bare refs collapsed into stable section anchors). Drift fix while sweeping: the row at line 90 cited `r3-structure.md:26, :52, :107` as "T-LensProducer-Retirement sub-gate 3 acceptance"; lines 52 and 107 had drifted off-target ("Lens framework" / `anthropic_wire_*` respectively). Replaced with the canonical anchors that actually carry sub-gate 3 acceptance: §"Summary" item 2, §"Acceptance — `.dag` gates" T-LensProducer-Retirement (`regen_lens_dot_rs_retired` row), and §"Lane structure" T-LensProducer-Retirement row.

Address BLOCKING review on PR #1831 (briansrls 2026-05-06T09:25Z). The previous sweep at 23274a5 preserved a drifted target: bare `r3-structure.md:59` / `:60` lived in §"Lane gating summary" (the 14-of-18 evaluator-gating roll-up), but the brief was citing them as authority for the `pb_self_compile_fixed_point` two-horizon semantics. That authority actually lives at r3-structure.md:89-90 under §"Acceptance — `.dag` gates" T-FixedPoint entry, "Two-horizon clarification" sub-bullet. Sweep preserved the drift instead of fixing it — same failure class as the r3-structure.md:52/:107 drift caught in 10e0355 on the regen-lens audit. Conversions (3 sites in the brief, all corrected): - §"Two-horizon framing": cite §"Acceptance — `.dag` gates" T-FixedPoint entry ("Two-horizon clarification" sub-bullet) - §"Acceptance gate (`.dag`)" intro: cite §"Acceptance — `.dag` gates" T-FixedPoint entry (`pb_self_compile_fixed_point` row + Two-horizon clarification) - "Two-horizon authority" footer cross-ref: same anchor Verification: `grep -n "Lane gating summary" docs/briefs/r3-pb-t-fixedpoint-worker.md` → 0 matches. `grep -nE '\.md:[0-9]+' docs/briefs/r3-pb-*.md` → 0 matches.

Per PB Mgr dispatch on inbox #1768 (sleek-eagle-514). Refreshes the per-surface inventory from `docs/audit/t-v2-retirement-migration-matrix.md` §2 against current `origin/main` HEAD. Docs-only; no code touched. No `src/v2/` deletion, no Cargo edge removal. Inventory + grep receipts only. Findings (refresh-class only — structural map unchanged): - Population A: 15 → 16 files (new: pb_method_template_projection_ consumability.rs). Same G-2 unit-retirement disposition. - Population B test-file line citations drifted (m2 L991→L1209 etc.); Cargo edge citations drifted (Cargo.toml L32-33 → L37-38). Constructs unchanged. - Population C dag.rs line set drifted (6 → 1 doc-comment at L1793). - 10 additional cosmetic files surfaced (gap-fill vs matrix §2.3). - Root `Cargo.toml` v2 references (L6/L8/L58/L61) inventoried — not previously listed in matrix. - G-1 closure surface count: 4 (unchanged). No new substantive v2_compiler consumer since matrix authoring at 66edec5. Cross-links every Population B/C row to migration-matrix § + S-1 input-packet decision row.

Thinking: 36s wall

Findings

docs/audit/t-v2-mechanical-inventory-2026-05-06.md:18 and :21 claim the canonical unified command is grep -rEln ... and that it “catches every surface enumerated below in one pass,” but -l only prints filenames, not line-level matches. That contradicts the later claim at :219 that the “unified single-grep census ... produces line-level enumeration.” This violates INVARIANTS.md’s “Documentation Describes Live State” / fail-closed bar: the reproducibility command as written cannot mechanically reproduce the line-numbered inventory the doc presents.

Verdict: REQUEST_CHANGES. The review-driven update is close, but the new “single unified census” methodology is overstated as written because the documented command cannot generate the line-level receipts the file now relies on.

Address codex REQUEST_CHANGES on PR #1850 sha f783475: `-l` prints filenames only, contradicting the doc's claim that the unified command produces "line-level enumeration" (§3 Δ7). The matrix cites `-rEln` because matrix is file-level inventory; this doc shifted to line-level but kept the `l` flag. Drop `l` → `-rEn`. Added a one-line note explaining the flag delta vs the matrix-cited form. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

Findings: None. The diff only updates docs/audit/t-v2-mechanical-inventory-2026-05-06.md: it tightens the canonical grep (-rEn, paths, regex), explains why line-level receipts need -n without -l, splits load-bearing data rows into C-data with explicit G-2 / S-1 routing (aligned with boundary / single-authority thinking in the rubric rather than contradicting it), and refreshes line-level inventory notes. Nothing here touches compiler substrate, Rust style (CODING.md), or tests (TESTING.md).

Verdict: APPROVE — Narrowly scoped audit follow-up; no diff-grounded violations of INVARIANTS.md, docs/modeling-discipline.md, CODING.md, or TESTING.md.

BLOCKING (1)

Root Cause

docs/audit/t-v2-mechanical-inventory-2026-05-06.md C-data routing conflates src/v3/compiler dev-dependency deletion with root workspace package removal → keep test_package routed only to G-2/root workspace removal, or name a separate S-1 G-2 decision for the CI test package.

⚠️ One routing contradiction needs correction before this audit can be the planning source.

+| Surface | Construct | Role | Population | G-1 / G-2 routing |
+|---|---|---|---|---|
+| `dsl/gunbc/compiler.dag:53` | `data compiler_source: SourceRoot = { path: "src/v2" }` | Configuration row pointing the compiler-source `SourceRoot` at the v2 source tree. Consumed as compile input; not a Rust import. | **C-data** (not C-cosmetic) | **G-2 prerequisite**, not G-1. Disposition is **routed to S-1** (PM-authored worker brief): does `compiler_source.path` retarget to a v3-side root when v2 retires, or does `compiler.dag`'s self-compile target itself refactor under T-FixedPoint / SG-0 = 0 closure? **No disposition proposed here**; flagged so S-1 enumerates it explicitly rather than letting it slip into a Population C cleanup pass that would silently drop the path value. |
+| `dsl/gunbc/compiler.dag:270` | `data test_package: NonEmptyStr = "v2-compiler-tests"` | Configuration row naming the Cargo test package the compiler-pipeline test driver invokes (`cargo test -p v2-compiler-tests …`). Consumed as a typed string constant; not a Rust import. | **C-data** (not C-cosmetic) | **G-2 prerequisite**, not G-1. Disposition is **routed to S-1**: does `test_package` retarget to a v3-side test crate (e.g. `v3-compiler-tests`) when `v2-compiler-tests` is removed, or does the test-driver authoring change shape under T-FixedPoint? Tied to Cargo edge §B.2 retirement: when the Cargo dep is deleted (Decision 3), this constant either points at a stale crate name or must be retargeted in the same PR. **No disposition proposed here**; flagged for S-1 scope coverage. |


…edge Address codex BLOCKING on PR #1850 (sha 15faffa): the C-data row at `dsl/gunbc/compiler.dag:270` (`test_package = "v2-compiler-tests"`) was incorrectly tied to §B.2 Decision 3 (G-1 dev-dep edge retirement). That conflates two distinct removals: - G-1 / §B.2 Decision 3: deletes the dev-dep edge in `src/v3/compiler/Cargo.toml` — consumer-side dependency removed, but the `v2-compiler-tests` Cargo package itself still exists at workspace root. - G-2 / root workspace removal: deletes `src/v2/tests` workspace member (§1.4 root Cargo.toml L8) — the published package name goes away. The data row points at a *package name*, which remains valid post-G-1 and only becomes stale at G-2. Re-routed to a separate S-1 G-2 decision (CI test package retargeting), explicitly not tied to B.2/Decision 3. Updated both §1.3 C.3 row and §2 cross-ref row to reflect the correction.

Findings

None that clearly violate INVARIANTS.md, docs/modeling-discipline.md, CODING.md, or TESTING.md. This diff only adjusts an audit markdown file (implementation-layer documentation, not substrate). Nothing touches fail-closed paths, duplicate compiler authority, Rust style, or tests.

Verdict

APPROVE — The changes tighten census methodology (unified grep, -rEn vs -rEln, broader src/v2\b coverage), split typed data rows into C-data with explicit G-2 / S-1 routing (consistent with boundary / single-authority thinking for retirement planning), and clarify compiler.dag:270 vs G-1 edge deletion. No actionable rubric breach found.

Exploratory observations (optional)

§2 vs §1.3 line anchors: docs/audit/t-v2-mechanical-inventory-2026-05-06.md still lists pb_method_template_projection_dag_emit_test.rs:28,54 in the §2 cross-reference table while §1.3 C.2 and summary item 7 include L24 as well. That line appears as unchanged context in the diff hunk around the §2 table edits; updating the §2 row to mention L24 would match the rest of the inventory (pure doc hygiene, not a principle violation).

cursor optional nit on PR #1850: §2 cross-reference table listed `pb_method_template_projection_dag_emit_test.rs:28,54` while §1.3 C.2 and §3 Δ7 include L24 too. Pure doc hygiene; line set now consistent (L24,28,54). Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

Findings: None. The diff only updates docs/audit/t-v2-mechanical-inventory-2026-05-06.md. Nothing here conflicts with INVARIANTS.md or docs/modeling-discipline.md in a concrete way: it is an audit artifact that tightens search methodology and separates cosmetic mentions from load-bearing .dag data rows (migration routing / scope clarity, not new compiler substrate). CODING.md and TESTING.md do not apply to this documentation-only change.

Verdict: APPROVE — The updates are narrowly scoped: unified grep recipe (-rEn, expanded paths/pattern), C-data vs C-cosmetic split for compiler.dag:53 and :270, and line-completeness notes. Spot-checking the cited references against the current tree shows compiler.dag and p0_std_render_repeat_string_test.rs match the documented lines.

Exploratory observations (optional): The opening still says every cell cites 2d26ed2b3 while the new HEAD verified paragraph describes follow-up methodology validated after the #1848 merge; a future refresh could align that sentence with the “re-pin HEAD” guidance so readers are not left wondering whether every line number is strictly pinned to one commit. Non-blocking documentation polish only.

cursor optional polish on PR #1850: intro said "Every cell below cites a live grep / file/line on 2d26ed2" while the HEAD verified note acknowledges follow-up validations after #1848. Aligned the two: initial cells pinned to 2d26ed2; follow-up additions validated post-#1848 merge; future refreshes should re-pin HEAD before citing.

Findings: None. The diff only updates docs/audit/t-v2-mechanical-inventory-2026-05-06.md. Nothing here changes substrate, Rust, or tests, so INVARIANTS.md, docs/modeling-discipline.md, CODING.md, and TESTING.md do not surface a concrete violation tied to this diff. The C-data split and explicit S-1 / G-2 routing are documentation that reinforces boundary/single-authority thinking for retirement scope rather than introducing a second code path.

Verdict: APPROVE — Narrow, mechanical audit follow-up (unified grep recipe, line-level completeness, C-data vs cosmetic). Framing that HEAD pins and line anchors can drift is appropriate for a living main tree.

That conflates two distinct removals: - G-1 / §B.2 Decision 3: deletes the dev-dep edge in `src/v3/compiler/Cargo.toml` — consumer-side dependency removed, but the `v2-compiler-tests` Cargo package itself still exists at workspace root. - G-2 / root workspace removal: deletes `src/v2/tests` workspace member (§1.4 root Cargo.toml L8) — the published package name goes away. The data row points at a *package name*, which remains valid post-G-1 and only becomes stale at G-2. Re-routed to a separate S-1 G-2 decision (CI test package retargeting), explicitly not tied to B.2/Decision 3. Updated both §1.3 C.3 row and §2 cross-ref row to reflect the correction.

Re-grep at HEAD 530c76e shows the migration already landed: - src/v3/compiler/src/dag.rs:1789-1791 doc comment names dsl/std/algebra.dag as the semantic authority and demotes v2 stage0 to "drift ratchet". - src/v3/compiler/src/dag.rs:3596-3605 typed accessor reads the lowered data kernel_algebra_profile Map directly. - src/v3/compiler/tests/integration/m2_substrate_inhabitance_test.rs:1239 v3_kernel_algebra_profile_reads_lowered_dag_map_authority ratchets v3 reading the lowered-Dag Map authority (P0 invariant).

Two findings; both valid: (1) Search authority was split across narrower greps. The matrix-cited `\bv2_compiler(_tests)?\b` only matches underscored module paths (v2_compiler / v2_compiler_tests) and misses the hyphenated Cargo dep names (v2-compiler / v2-compiler-tests). Receipts in §1.2 B.2 used a separate Cargo-only grep to compensate, but the cited "search authority" header didn't reflect that. Replaced with a single unified census: grep -rEln 'src/v2/|\bv2[-_]compiler(_tests|-tests)?\b' src/ Cargo.toml dsl/ This catches every surface in one pass. Also surfaced one missed file under the broader pattern: `dsl/gunbc/tools/ci_runner.dag:16` (doc-comment with `cargo run -p v2-compiler` invocation example). (2) `.dag` configuration-data refs were misclassified as Population C cosmetic. `dsl/gunbc/compiler.dag:53` `data compiler_source: SourceRoot = { path: "src/v2" }` is a typed data declaration consumed by the compile pipeline — silently rewriting it during a cosmetic G-2 sweep would either invalidate `compiler_source` or quietly retarget the compile root without an authoring-time decision. Reclassified as a new C-data row (§1.3 C.3) with named G-2 routing to S-1 (input-packet Decision 6 scope coverage) rather than C-cosmetic "sweep at G-2" default.

Reviewer claimed the unified grep `\bv2[-_]compiler(_tests|-tests)?\b` misses three sites; verified directly: regex catches all three. The substantive issue is **inventory line-completeness**, not regex coverage — earlier passes enumerated FILES not all line-hits within files. Fixes: - Population B `p0_std_render_repeat_string_test.rs`: add L25 body-of- test call to `v2_compiler::v2_std_core::diagnostic_to_message` (matrix §3.1 only listed `use`-decls L9-L11; this is a 4th substantive line in the same file). Same Decision 1 disposition. - Population C `pb_method_template_projection_dag_emit_test.rs`: add L24 (was L28/L54). - Population C `SELF_HOSTING.md`: add L1178 (`cargo test -p v2-compiler-tests ci_freshness` doc reference). - Population C-data: add 2nd row, `dsl/gunbc/compiler.dag:270` `data test_package: NonEmptyStr = "v2-compiler-tests"` — typed config naming the Cargo test crate, tied to Cargo edge §B.2 retirement. Same C-data class as compiler.dag:53; routed to S-1. Net G-1 closure surface count: still 4 (unchanged — L25 is in an already-counted Population B file). C-data sub-class: 1 → 2 entries.

The new §Delta (2026-05-06) table inadvertently used `-rcE` (count-only). Aligned with the rest of the file; flag now consistent across all 8 grep invocations in §A and §Delta tables. Non-blocking nit only; no semantic change. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * docs(briefs): clarify markdown-table escape note in §Delta grep cells Address codex REQUEST_CHANGES on merged PR #1926 (sha c68800f, openai-pro review 2026-05-07T00:27Z): \`\|\` inside table cells under \`grep -E\` is ambiguous in raw markdown source — \`\|\` is a markdown-table escape that renders as \`|\`, but a reader copying the raw source into a shell would get a literal pipe (no alternation). Verified both parses at HEAD \`2c7d82031\`: - as-written (literal \`\|\`): 0 matches - as-rendered/alternation (\`|\`): 0 matches The audit's "no material delta" verdict holds under either parse. The \`\|\` convention is load-bearing across the file (§Population A row cells at L25/L35/L45/L55, prior §Delta table at L183-186) — so the fix is to add a clarifying note above the §Delta table explaining the markdown-table escape, not to break the existing convention. Followup PR (since #1926 already merged before review arrived).
