docs(r3): Lane 2 corpus seed shape spec — BoundDeclaration-leveraged authoring (research)

[briansrls]

Dispatch (R3 Verification Mgr → calm-gull-455)

Pre-authors Lane 2 corpus seed shape against merged import contract (#1421/#1443/#1444) + extension spec (#1412) while #1449 is still OPEN.

Contents

• §1 — Expected BoundDeclaration sum from feat(v3): add BoundDeclaration substrate carrier #1449 (StaticBound(Interval<Int>) | PlatformDependent) with explicit verify-on-merge caveat.
• §2 — Substrate honesty: carrier does not collapse Mechanism (a) program (source, file_name) / claim_name join; optional §P1 composition later.
• §3 — Illustrative add_then_branch shared-module sketch + optional bound adjunct after consumers exist.
• §4 — CI ratchet (TestClaimValue / assert_eq! on source+file_name), OnceLock + cached_compile, ClaimResult shape asserts, DB‑3/DB‑20 pointer.
• §5 — Path receipt (+ note to add this file to loop post-merge); post‑feat(v3): add BoundDeclaration substrate carrier #1449 rg smoke.

Constraints respected

• Docs only — no substrate, fixtures, or TestPredicate edits.

Manager review — APPROVE; principled "no fit" finding preserves substrate-state honesty

Strong execution. The load-bearing finding is §2's honest "no fit" answer to the BoundDeclaration unification question — dispatch invited exploring whether BoundDeclaration could enable a tighter corpus shape; you honestly answered NO and preserved Mechanism (a) paired-string authority.

Substantive findings

1. Pre-merge honesty preserved (§Status + §1):
   • Explicit "Does not claim PR feat(v3): add BoundDeclaration substrate carrier #1449 is merged."
   • Post-merge re-verification step in §1 ("re-verify §1 against src/v3/std/substrate.dag at origin/main HEAD").
   • Honesty footnote: "git grep -n '^type BoundDeclaration' src/v3/std/substrate.dag on origin/main before feat(v3): add BoundDeclaration substrate carrier #1449 returns nothing — that is expected."
   • §5 smoke check requires confirming the two-variant sum lands as expected.
   • feedback_verify_thesis_claims discipline applied at spec-authoring time.
2. §1 Expected carrier shape — BoundDeclaration = StaticBound(Interval<Int>) | PlatformDependent taken from PR feat(v3): add BoundDeclaration substrate carrier #1449 summary; semantics commentary explicit ("Slice A is carrier-only: no parser/lowerer syntax, no Grounding projection reader, no per-target inhabitance population in the same PR"). Bounded scope respected.
3. §2 No-fit finding (load-bearing): "BoundDeclaration answers coercion-fold bind-shaped bounds over Interval<Int>, not corpus program text. It does not replace Mechanism (a)'s paired program authority or merge source + file_name + row key into one nominal at feat(v3): add BoundDeclaration substrate carrier #1449."
   • Dispatch invited exploration; you honestly answered NO rather than forcing a fit. That preserves substrate-state honesty (feedback_verify_thesis_claims at architectural level) — BoundDeclaration is a different concern (static value-domain bounds, not corpus authoring).
   • Forward-looking option flagged in same section: "If strict rows need machine-checked static bounds alongside program text, a Director-ratified substrate record could compose paired program identity with bound metadata carried as BoundDeclaration after coercion-fold consumers exist — not a fixture workaround (INVARIANTS §P1)." Doesn't force now; preserves option later.
4. §3 Pre-authored seed shape:
   • §3.1: Mechanism (a) paired-binding pattern with illustrative path (src/v3/compiler/tests/fixtures/corpus/r3_certification_corpus.dag) + per-row paired binding sketch.
   • §3.2: Optional BoundDeclaration adjunct as orthogonal post-§P1 consumer (sketch-only; doesn't replace Mechanism (a)).
   • Ground-truth bytes today: sidecar add_then_branch_seed.v3 remains byte authority until generator (b) replaces.
5. §4 CI ratchet shape concrete — TestClaimValue::from_declaration projection + assert_eq! source + file_name. ClaimResult variant-shape-only assertions per TESTING.md. DB-3/DB-20 posture preserved.
6. §5 Live-path verification receipt — 11-path git cat-file -e shell loop covering all hyperlinked paths. Path-grounding discipline applied.
7. §6 Re-engagement triggers explicit — (1) feat(v3): add BoundDeclaration substrate carrier #1449 merge → verify §1-§3; (2) fixture/module PR → implement §3.1 or fall through to (b). Concrete dispatch boundaries.

Discipline respected

• No substrate edits ✓
• No new TestPredicate variants ✓
• No fixture authoring ✓
• Doesn't claim feat(v3): add BoundDeclaration substrate carrier #1449 merged ✓
• Honest "no fit" finding preserves substrate-state honesty ✓
• INVARIANTS §P1 routing for any future composition ✓
• Path-grounding discipline (§5 git cat-file shell loop) ✓
• DB-3/DB-20 posture preserved ✓
• TESTING.md shape-only assertion discipline ✓

Manager observations

• The §2 "no fit" finding is the kind of substrate-state honesty that prevents future architectural drift. Dispatch invited a fit; you said "no fit, here's why" with concrete reasoning. That's better than fabricating a forced unification.
• §3.2 "Optional BoundDeclaration adjunct" preserves the forward option (Tier-2 strict rows with machine-checked static bounds) without forcing it now. Future-flexible without speculative coupling.
• Post-feat(v3): add BoundDeclaration substrate carrier #1449 smoke check (§5 final paragraph) — "if Substrate adjusts naming/payload during review, update §1 before relying on this brief for implementation dispatch" — anchors the spec-revision trigger explicitly.

Status: approved. Lane 2 corpus seed pre-authoring lands as the dispatch-ready spec; one-shot dispatchable post-#1449 merge with explicit verify-against-merged-shape caveat. cool-crab + loyal-ibex stay on hold pattern per Director ratification.

Verdict: APPROVE

Docs-only proposal, explicitly marked research-only, with bounded non-goals and re-engagement triggers for #1449 / fixture implementation. I didn’t see concrete violations of the pinned modeling, coding, or testing discipline in the diff.

Non-blocking — Improvements (fix in-PR if easy, else defer to roadmap)

• docs/briefs/r3-v-lane2-corpus-seed-shape-spec.md In §4, say the join is TestClaim.name projected through TestClaimValue.claim_name, since claim_name is not a field on TestClaim; defer with the Fixture/module PR lane if not fixed here.

✅ No blocking concerns; the brief stays research-only, preserves the paired program identity authority, and correctly keeps BoundDeclaration separate from corpus text.

Verification (calm-gull-455) — APPROVE relay vs PR tip

Re-read origin/docs/r3-lane2-corpus-seed-shape-spec @ 349c48f01 (PR #1453, still OPEN): manager bullets match landed prose — §Status does not claim #1449 merged; §1 expected two-variant BoundDeclaration + carrier-only Slice A boundary + git grep honesty + post-merge §1 refresh; §2 no-fit alignment (coercion-fold / Interval<Int> vs Mechanism (a) paired program authority + claim_name join); §3.1/§3.2 seed sketch + orthogonal adjunct; §4 TestClaimValue::from_declaration + assert_eq! + ClaimResult shape / TESTING / DB‑1–C‑5 / DB‑3–DB‑20 pointers; §5 11-path git cat-file loop + post-merge self-path note + §5 rg smoke caveat; §6 re-engagement triggers.

No further commit — APPROVE consistent with branch tip pending merge.

Codex NON-BLOCKING (§4 join key) — fixed

§4 step 2 now states the cross-lane join is **** on substrate and **** is **** projected through **** (no separate claim_name on .dag TestClaim).

Codex NON-BLOCKING (§4 join key) — fixed

§4 now states the cross-lane join is substrate TestClaim.name, and TestClaimValue.claim_name is name projected through TestClaimValue::from_declaration (there is no separate claim_name field on the .dag TestClaim record).

Findings

None. The diff only adds docs/briefs/r3-v-lane2-corpus-seed-shape-spec.md. It is labeled as research/proposal, does not treat unmerged work (#1449) as landed, and points at post-merge verification. Nothing here contradicts INVARIANTS.md or docs/modeling-discipline.md in a concrete way: it reinforces single-authority corpus pairing (P2), optional future composition with explicit triggers, and ratchet guidance that matches TESTING.md (match ClaimResult by variant, avoid diagnostic substring pinning — see the §4 bullets and rust/assert sketch). CODING.md does not apply (no Rust).

Verdict

APPROVE — Narrowly scoped research brief; careful about dependencies and receipts; no documented invariant or testing-discipline violations in this diff.

Exploratory observations (optional)

• §1 vs §3.2 terminology: §1 frames StaticBound over Interval<Int>, while the §3.2 sketch uses BoundedInterval { lower, width }. That is consistent with “illustrative / PROPOSAL” but could be clarified later so readers do not read two different carriers for the same idea — non-blocking, doc-polish only.

Correction (calm-gull-455) — garbled PR comment in relay

The relayed thread text with empty bold markers was from an earlier gh pr comment --body "..." attempt where the shell interpreted backticks. The brief itself was never wrong after 8ed81fe7e.

Authoritative §4 step 2 on branch docs/r3-lane2-corpus-seed-shape-spec reads:

Join: locate structural TestClaim declarations whose substrate name field matches across lanes (verification.dag). TestClaimValue.claim_name is name projected through TestClaimValue::from_declaration — there is no separate claim_name field on the .dag TestClaim record.

Tip: merge 8ed81fe7e; ignore empty-bold artifacts from shell-mangled --body paste on the same thread.

Verification (calm-gull-455) — composer-2 APPROVE @ 8ed81fe7 + exploratory

Scheduled review has no blocking findings; narrow docs-only PR stays consistent with PROPOSAL posture, #1449 honesty, P2 pairing, and TESTING-style harness bullets.

Exploratory (§1 vs §3.2): Addressed in d136efa78 — §3.2 now states BoundedInterval { lower, width } is the bounded variant inside substrate Interval<Int> (sibling Unbounded), i.e. the same carrier StaticBound(Interval<Int>) from §1, not a separate nominal.

Review complete: the diff only adds docs/briefs/r3-v-lane2-corpus-seed-shape-spec.md (research brief). No Rust, tests, or substrate edits.

Findings: None. Nothing in the diff contradicts INVARIANTS.md, docs/modeling-discipline.md, CODING.md, or TESTING.md in a way that needs a cited violation: the brief is explicitly PROPOSAL/research-only, defers §1 to post–#1449 verification (docs/briefs/r3-v-lane2-corpus-seed-shape-spec.md lines 3–4, 26–27), keeps program identity authority separate from BoundDeclaration (lines 36–38), and §4 points harness expectations at TESTING-style assertions (variant shape, not diagnostic substrings) (lines 79–84).

Verdict: APPROVE — Narrow documentation addition; rubric-aligned framing (honesty about unmerged upstream, P1/P2 citations, explicit non-goals and re-engagement triggers). No actionable invariant or style breach in this diff.
