docs(r3-close): Gap 9 substrate-landed status update — sum-variant Correction carrier verified at HEAD (Phase 2.5) - #3070
Conversation
…m-variant Correction carrier verified at HEAD; consumer-tier work activates
Phase 2.5 per dispatch plan §1 task table — original deliverable was "author Gap 9 substrate-shape canvas as PM-direct deliverable for Director + Substrate Mgr sign-off." Substrate-state grep 2026-05-14 surfaced that the canvas-authoring step is ALREADY DONE.
src/v3/std/diagnostics.dag contains the spec-matching substrate:
- `type Correction = LiveCorrection { witness: CorrectionWitness } | DeferredCorrection { reason: String, retirement_plan: RetirementPlan }` (lines 67-69)
- `type CorrectionWitness { description, span, new_source }` (lines 37-44)
- `type RetirementPlan { owner, exit_condition }` (lines 49-52)
- `type Diagnostic { ..., correction: Correction }` — mandatory field (line 154)
Matches Gap 9 §4 spec exactly (sum-variant Correction, NOT Option<Witness>); per feedback_state_space_vs_behavioral_invariants + feedback_practice_2_vs_4_same_variant_vs_cross_variant discipline. §1.8 gate #106 also landed per PR #3027.
Gap 9 Plan-to-cash + sub-program updated to reflect substrate-landed status:
- HEAD evidence: substrate carriers LANDED with line citations
- What's missing: now consumer-tier (per-diagnostic-class audit + test-corpus ratchet absolute-100% LiveCorrection)
- Owner: warm-wolf-698 (substrate DONE) → still-moth-538/tidy-ram-467 (Verification Mgr; consumer audit + ratchet enforcement)
- Sub-program: substrate-step DONE; consumer-step ACTIVE; remaining steps reframed
Test-corpus ratchet (absolute 100% per operator §4 Item 4 IN-R3 ratification 2026-05-13): every fired Diagnostic value carries LiveCorrection variant; count(DeferredCorrection) = 0 across test corpus.
Operator visibility net: Gap 9 is MORE-progressed than close plan currently documents — substrate landed; show-correct-code worker brief dispatch is now unblocked at substrate-prereq tier (was previously documented as canvas-authoring-blocked).
Phase 2.5 per dispatch plan §1.

reconciled with substrate-landed state + Status upgrade DECLARED → CANVAS_RATIFIED codex BLOCKING #11733 at PR #3070 — §1.8 row #106 narrated OLD shape ("Diagnostic { ... fixes: List<Correction> }" + "SELF_HOSTING.md still names correction: Option<Correction>") as CURRENT state while my PR's close-plan Gap 9 update claimed substrate landed. P2 single-authority violation: close-plan Gap 9 said "Substrate carriers LANDED at HEAD" but §1.8 row #106 said old shape current. Verified per feedback_corrections_must_grep_verify_source: - src/v3/std/diagnostics.dag:154 carries `correction: Correction` (mandatory; landed) - lines 67-69 carry the ratified sum: LiveCorrection { witness: CorrectionWitness } | DeferredCorrection { reason: String, retirement_plan: RetirementPlan } - lines 37-44 + 49-52 carry CorrectionWitness + RetirementPlan respectively - src/v3/SELF_HOSTING.md lines 1829 + 1916 align (mandatory `correction: Correction`; NO `Option<Correction>` text present at HEAD — codex's claim about SELF_HOSTING.md was outdated, but the §1.8 row #106's CLAIM about SELF_HOSTING.md was the stale text) Fix (in same PR per codex's directive "if this PR wants to claim substrate-landed status is now HEAD truth, ledger entry needs updating in same change"): - Status field: DECLARED → CANVAS_RATIFIED per the row's own status progression ("CANVAS_RATIFIED when the Substrate Mgr canvas ratifies the mandatory sum carrier" — which has happened) - Description section: replace stale "current substrate carries fixes: List<Correction>" + "SELF_HOSTING.md still names Option<Correction>" with substrate-landed citation (line numbers + actual carrier shape); historical framings marked superseded; row continues rejecting any future nullable/list-revival - Ratified shape section: "Ratified substrate-shape proposal" → "Ratified substrate-shape (now LANDED)"; Witness → CorrectionWitness (precise type name) Both close-plan Gap 9 (this PR's docs/r3-actual-close-plan.md edits) + §1.8 row #106 (this commit) now describe the same substrate-landed state — single-authority ledger restored.

docs/r3-program-plan.mdstatus promotion relied on stale substrate-state evidence → either land the referencedCorrection/Diagnostic/SELF_HOSTINGsource updates in the stack/base or keep #106 in the pre-landed DECLARED/proposed state until the source authority actually changes.

(1) **Substrate-level (primary)**: collapse `Lookup<C>::Miss` → `Witness<C>::Violates { reason, at }` across the 70 sites; Phase 1 cost.dag + complexity.dag bundle (50 sites; canonical pattern — `complexity_of` + `symbolic_cost_of` lens read-channel + helpers), Phase 2 monomorphized accessor sweep (substrate.dag 3 + algebra.dag 3 + infer_helpers.dag 3 = 9 sites; `miss_*_lookup` / `hit_*_lookup` constructor pairs at `substrate.dag:691,695` + `algebra.dag:225,229` + `Lookup<DeclarationId>` return-type at `infer_helpers.dag:141` + doc references at `algebra.dag:219` + `infer_helpers.dag:77,88`), Phase 3 lookup.dag terminal carrier deletion (11 sites + carrier itself). (2) **Testgen-level (companion)**: per-lens TestClaim asserting universal coverage `∀ bind ∈ bootstrap. lens_read(bind) ∈ Inhabits(_)`; fail-closed on `Violates`. Violates set becomes structural test fixture (named-reason enumeration of legitimate exclusions). Without (2), (1) leaves regression window; without (1), (2) has nothing to test. **Two-part predicate** (per Director ratification): Part A (terminal, primary) = `git grep -nE "Lookup<" src/v3/lenses/ src/v3/std/ ; expected = 0` (terminal state after Phase 3 lookup.dag deletion); Part B (regression guard) = `git grep -nE "::Miss\b" src/v3/compiler/src/lens_*_generated.rs ; expected = 0`. Both must pass = green. **Status progression**: DECLARED → CONSUMER_LANDED requires BOTH (a) Substrate Mgr brief authored covering ≥3 lens carriers AND (b) at least one universal-coverage TestClaim landed → PASSING requires Part A + Part B predicates both zero. **Canvas-framing** (operator-surfaced 2026-05-12 23:09Z; relayed to Substrate Mgr in brief): Q-MissOrError (why Miss instead of Error → answer: Miss carries neither reason nor at, forces caller to ignore or fabricate; correct shape is `Witness<C>::Violates { reason: <named diagnostic>, at: <port behavior> }`); Q-WhyTestgenMissed (3 structural gaps: (a) TestClaim rows scenario-driven not universal-property-driven, (b) parity tests pin frozen v2-oracle snapshots not v3-coverage sweeps, (c) lens-discipline ratchet didn't exist — fix substrate, testgen has property to enforce). **Authority chain**: operator 2026-05-11 + audit §0/§3.1/§3.4 + design-lens-framework.md:51,326,382-384 + design-emission-model.md:958,1206 + R4.D §4 (WISHLIST.md:147 from PR #2800) + R4.D faithfulness framework. **Origin**: Director's 2026-05-12 complexity-lens dump (msg_32a3775e) surfaced concrete evidence of 15 Miss returns at algebra.dag bind layer; operator surfaced the audit-doc precedent; Director provided concrete grep counts (msg_cefcbe05; subsequently superseded — see scope correction below); PM proposed §1.8 row (msg_054e2a43); Director ratified (b) with refinements (msg_915aa2c1). **Scope correction at PR #2807** (codex BLOCKING #4276876807): Director's relayed 64-count omitted 2 files (`algebra.dag` 3 + `infer_helpers.dag` 3 = 6 missing sites). PM verified Part A predicate at `7a7c19d3` HEAD = 70 matches; algebra.dag inclusion is structurally required since `algebra.dag:225 miss_symbolic_cost_lookup()` is the canonical `Lookup<SymbolicCost>::Miss` constructor at the bind layer that emits the 15 Miss returns Director's dump surfaced — excluding it would have left the row's own terminal predicate red post-migration.

@codex schedule-review summary on commit `6427173b` (177s wall) — same finding as the inline BLOCKING I just refuted at `docs/r3-program-plan.md:333`. Per dashboard verification protocol, claim factually contradicted by grep-verified source: Codex claim: "status promotion relied on stale substrate-state evidence" — i.e., Verified at HEAD:
Substrate ratified shape IS LANDED on origin/main. The §1.8 row #106 CANVAS_RATIFIED status accurately reflects source authority at HEAD; no drift between row #106 and source. See full grep verification in my prior reply at PR #3070 (`#issuecomment-4449143930`). codex's specific line citations (37/129/1906) point at unrelated content (CorrectionWitness; LensInstanceKindWitness; correction-pattern prose) — codex may be reading stale ledger snapshots or hallucinating line refs.

1. Story of the diffThis PR is a docs/status reconciliation for R3 Gap 9, not an implementation change. It updates the close plan from “the diagnostic-correction substrate is missing” to “the substrate carrier has landed; consumer-tier audit and ratchets are now the remaining work,” with the load-bearing shape recorded as a mandatory 2. Invariant categories
Compliant — the diff does not modify substrate declarations directly, but it treats the substrate as the authority and records the landed carrier shape rather than introducing a parallel planning shape:
Compliant — illegal-states-unrepresentable / fail-closed discipline is preserved: the diff explicitly rejects nullable/list authority and records that no
N/A — diff is Markdown planning/status only; no Rust implementation, helper placement, method/free-function shape, or error/result API is changed.
Compliant — no tests are required for the doc-only status update itself, and the diff keeps the future test obligation concrete: every fired diagnostic must carry
N/A — no locked design document is changed. The changed docs preserve the thesis-level diagnostic promise quoted in the close plan, rather than relaxing it (
Compliant — 2.5. Top-down PM intent reviewCompliant — this PR preserves the PM-level intent behind Gap 9. The thesis promise remains “diagnostics should point to the structurally correct program,” and the diff does not convert that into optional guidance: it records 3. VerdictAPPROVE. The diff is a clean status reconciliation: it removes stale “missing substrate” framing, records the landed sum-variant carrier as the single authority, and keeps the remaining consumer/test work explicitly bounded rather than silently declaring the gap closed. |

Summary
Phase 2.5 of corrective sweep per dispatch plan §1.
Substantive discovery 2026-05-14: The Gap 9 substrate-shape canvas that the close plan documented as "needs Mgr canvas authoring before worker dispatch" is ALREADY LANDED at
src/v3/std/diagnostics.dag:type Correction = LiveCorrection { witness: CorrectionWitness } | DeferredCorrection { reason: String, retirement_plan: RetirementPlan }(lines 67-69)type CorrectionWitness { description, span, new_source }(lines 37-44)type RetirementPlan { owner, exit_condition }(lines 49-52)type Diagnostic { ..., correction: Correction }— mandatory field (line 154)Matches the close-plan Gap 9 §4 spec exactly (sum-variant Correction, NOT
Option<Witness>; perfeedback_state_space_vs_behavioral_invariants+feedback_practice_2_vs_4_same_variant_vs_cross_variant). §1.8 gate #106 also landed per PR #3027.Changes
Operator visibility net positive
Gap 9 is MORE-progressed than the close plan currently documents — substrate landed; show-correct-code worker brief dispatch is unblocked at substrate-prereq tier. Originally documented as canvas-authoring-blocked; actually consumer-tier ready.
