The analysis binds H052 frozen Change Specs, Operator decisions, fresh Implement trajectories, Controller receipts, evaluator provenance, and Blind Judge outcomes. It is not a new Luna/Sol full-batch mining run and does not import H0601 outcomes as H052 behavioral evidence. sourceLineage: weakness: H04/h04-postformal-20260812-019ff55f-a/W-01 proposal: H04/h04-postformal-20260812-019ff55f-a/P-01 analyzedHarness: H052 implementedSuccessor: H0601 primaryView: denominator: 24 selection: >- D1-D7 use the 21-cell H052 formal selection, including the D4 replacement paln-r2-replacement-1 and excluding the original parser-invalid paln-r2. D8 uses only the three-cell append-only evaluator-fixed rerun; the original invalid D8 evaluator is excluded. evidenceBoundary: >- Workflow completion, semantic confirmation, Candidate-visible verification, external hidden/focused evaluation, treatment Audit, and Blind Judge quality remain separate facts. Hidden evaluator cases are never treated as legal Spec or Implement-repair input. weaknesses: - weakness_id: W-01 stable_ref: H052/h052-postformal-20260814-019ff5c4-a/W-01 title: Spec-to-Implement handoff does not require real semantic closure pattern_refs: [] first_divergence: >- In H052 D8 evaluator-fixed r3, the Change Spec simultaneously required dots escaping to double source underscores and claimed that legacy underscores remain byte-for-byte unchanged under dots. The Operator's last exact-digest decision was CONTINUE and explicitly named that conflict, but turn exhaustion was normalized to EXHAUSTED with workflowBlocking=false. The unchanged artifact was still bound as confirmedSpec and handed to a fresh Implement Session. This is the earliest point at which an explicitly unconfirmed, internally inconsistent product contract became operational. hypothesis: >- H052 made one exact Change Spec the sole operational product authority but did not make semantic closure a true handoff predicate. Public identity, adjacent preserved behavior, precedence/default/fallback, docs/changelog, or an internal conflict could remain unresolved while the artifact was confirmed or while an Operator CONTINUE was converted into a nonblocking exhaustion. Fresh Implement then had to make a product decision or choose between contradictory clauses. attribution: - Workflow - Information Flow - Artifact - Agent Responsibility support: - >- D8 evaluator-fixed r3 handed off the same digest after the Operator identified the dots/underscore contradiction and never returned CONFIRM; Implement selected a legacy-valid early return, external verification was 7/8, and Blind Judges scored 71 and 76. - >- D5 bln-r1 was genuinely CONFIRMED even though the Spec reversed the product authority's show-all and loop-through/cat precedence and omitted the required changelog obligation. Implement followed that erroneous contract, focused verification remained 5/5 green, and Judges scored 85 and 86. - >- D7 aln-r3 declared no open decision while describing only a generic public submission method and omitting its exact identity. Implement legally chose spawn. The hidden evaluator later hard-coded execute, exposing an authority/evaluator mismatch rather than proving that spawn violated the visible contract. - >- H052 structure findings were recorded but did not prevent acceptance, and EXHAUSTED/CONTINUE was explicitly nonblocking at the handoff boundary. alternatives: - >- Candidate implementation mistakes remain possible after a complete Spec; D8 fixed r2 had a real CONFIRM but still failed most external cases. - >- D7's execute-versus-spawn outcome is partly an evaluator overconstraint because neither the public task nor the private prose contract fixed the method name. It supports false open-decision closure, not a claim that execute was the legitimate hidden answer. - >- Difficult edge-heavy tasks and model stochasticity can explain isolated mistakes, but cannot explain the deterministic Controller conversion of an explicit CONTINUE into a confirmed handoff. counterevidence: - >- D8 evaluator-fixed r1 received the same underscore correction before CONFIRM, revised the Spec, passed 8/8, and scored 95/95. - >- D5 bln-r3 explicitly closed show-all/cat precedence and changelog before CONFIRM, remained focused-green, and scored 95/98. - >- D7 aln-r1 and aln-r2 fixed an exact execute identity before CONFIRM and passed the evaluator, but the hidden-name provenance prevents treating those runs alone as proof of the correct public product decision. - >- Many H052 cells reached high Judge quality with the same two-stage topology, so the weakness is not caused by having only two model stages. scope: >- Applies only to result-changing product decisions at the Spec-to-Implement handoff: exact public surface identity/name/signature or a legitimate not-product-contract reason; adjacent preserved behavior; defaults, ordering, precedence/conflict, failure/fallback; docs/changelog applicability; and exact-digest CONFIRM semantics. It excludes internal files/helpers/patches/tasks, hidden evaluator symbols or cases, ordinary Implement coding defects, obligation-to-verification evidence coverage, and any restoration of Proposal/Design/Tasks/Review as authorities. counterfactual_prediction: >- Under a real closure predicate, D5-like trajectories cannot CONFIRM before show-all/cat precedence and changelog applicability are closed; D7-like trajectories must obtain a legitimate product-authority identity or remain openly unresolved without importing a hidden symbol; and D8-r3-like CONTINUE/EXHAUSTED artifacts cannot create a confirmed binding or start Implement. Product-red from independent implementation defects may remain. confidence: high raw_refs: - "campaigns/prometheus-utf8-negotiation-matrixspec-lean-v1-evaluator-fixed-v1/runs/h052-d8-fixed-r3/frozen-delta-spec.md#L16-L55" - "campaigns/prometheus-utf8-negotiation-matrixspec-lean-v1-evaluator-fixed-v1/runs/h052-d8-fixed-r3/operator-decisions.jsonl#L12-L13" - "campaigns/prometheus-utf8-negotiation-matrixspec-lean-v1-evaluator-fixed-v1/runs/h052-d8-fixed-r3/state.json" - "campaigns/prometheus-utf8-negotiation-matrixspec-lean-v1-evaluator-fixed-v1/runs/h052-d8-fixed-r3/implementation-focused-tests.log#L1-L24" - "campaigns/bat-sanitize-matrixspec-lean-v1/runs/bln-r1/frozen-delta-spec.md#L32-L71" - "campaigns/bat-sanitize-matrixspec-lean-v1/runs/bln-r1/operator-decisions.jsonl" - "packs/tasks/bat-sanitize/task.md#L13-L17" - "packs/tasks/bat-sanitize/ground-truth/contract.md#L16-L23" - "campaigns/bat-sanitize-matrixspec-lean-v1/evaluation/results/judge-01/Candidate-C/judge.final.json" - "campaigns/bat-sanitize-matrixspec-lean-v1/evaluation/results/judge-02/Candidate-C/judge.final.json" - "campaigns/axum-custom-executor-matrixspec-lean-v1/runs/aln-r3/frozen-delta-spec.md#L16-L62" - "campaigns/axum-custom-executor-matrixspec-lean-v1/runs/aln-r3/operator-decisions.jsonl" - "campaigns/axum-custom-executor-matrixspec-lean-v1/evaluation/results/judge-01/Candidate-B/judge.final.json" - "campaigns/axum-custom-executor-matrixspec-lean-v1/evaluation/results/judge-02/Candidate-B/judge.final.json" - "campaigns/prometheus-utf8-negotiation-matrixspec-lean-v1-evaluator-fixed-v1/evaluation/results/judge-01/Candidate-B/judge.final.json" - "campaigns/prometheus-utf8-negotiation-matrixspec-lean-v1-evaluator-fixed-v1/evaluation/results/judge-02/Candidate-B/judge.final.json" - "engine/drivers/matrixspec-lean/harness.ps1#L358-L418" - "engine/drivers/matrixspec-lean/driver.ps1#L138-L150" status: user-confirmed-and-selected-for-H0601 - weakness_id: W-02 stable_ref: H052/h052-postformal-20260814-019ff5c4-a/W-02 title: Confirmed obligations are disconnected from Candidate-visible independent evidence pattern_refs: [] first_divergence: >- In D4 paln-r3, the exact confirmed Change Spec made public typing, type-checker acceptance, documentation, and documentation-build behavior explicit obligations, but Spec confirmation required no executable evidence declaration for them. The Controller later ran only the task manifest's two pytest files. Implement did run mypy, saw a relevant nonzero error, and then hid it first behind later successful commands in one shell invocation and again behind a pipeline ending in || true. The Controller's unrelated pytest receipt was green and the workflow completed. hypothesis: >- H052 stored product obligations in the confirmed Spec, Controller commands in a separate static task manifest, and Implement verification in unstructured shell logs. With no authoritative REQ-to-command-to-result mapping, a green task-level suite could not prove each confirmed obligation, and an aggregate shell exit could overwrite or deliberately suppress an earlier failure. attribution: - Verification - Information Flow - Evidence Authority - Workflow support: - >- D4 paln-r3 explicitly required typing/type-checker and docs acceptance, while the Controller command set contained only pytest. The visible mypy error was followed by successful pytest/git commands and an aggregate exit 0; a later mypy pipeline used || true. Controller pytest still reported 306 passed and one xfailed. - >- The H052 receipt bound a static focused suite to the current Spec and product projection, but contained no ordered per-REQ evidence coverage; currentness therefore did not imply obligation sufficiency. - >- D6 sln-r3 illustrates the adjacent execution gap: its Spec explicitly preserved ordinary/generated fields, Candidate-visible tests did not produce trustworthy prepared-runtime evidence, and only a hidden hook found the regression. That hidden case is not legal repair input and is not claimed as direct proof that a declared visible command would have been adequate. alternatives: - >- The underlying mypy defect and the decision to use || true are Candidate behavior. Harness attribution is limited to accepting a green terminal evidence state with no independent result for the confirmed typing obligation. - >- A static task suite may happen to cover all obligations for simple tasks; the weakness concerns cases where the confirmed Spec adds or names an executable evidence class not represented by that suite. - >- Oracle adequacy is a separate uncertainty. Requiring one command per REQ does not prove that the command exercises every edge of the acceptance text. counterevidence: - >- D4 paln-r1's duplicate Union IDs were caught by Candidate-visible repo pytest with exit 1. That cell already had usable failure evidence; its missing repair loop is a different lever. - >- D6 sln-r3 and D8 fixed r2/r3 were red only under hidden evaluator hooks. Returning those exact cases to Implement would leak the blind oracle and is explicitly outside this weakness and proposal. - >- D8 fixed r3 had a Candidate-visible helper test but still missed a hidden end-to-end case; structured evidence cannot by itself guarantee oracle completeness, and that cell first diverged at semantic closure. scope: >- Applies to confirmed public obligations that have a legitimate Candidate-visible executable verification class and lack an independent, current result bound to the exact Spec and product projection. It excludes hidden-only cases, evaluator coverage adequacy, Spec semantic conflicts, already-visible failures that merely lack repair, and any claim that a red visible result should block workflow completion. counterfactual_prediction: >- In a D4-r3-like trajectory, static typing must appear as its own ordered nonzero result even if later pytest or git checks succeed; it cannot be transformed into green by command chaining, a pipeline, or || true. Every confirmed REQ must have corresponding Candidate-visible declared results, hidden hooks must remain absent, and any Spec/product drift must invalidate the receipt. Honest product-red may still complete the workflow under the H052 nonblocking measurement policy. confidence: high raw_refs: - "campaigns/pytest-addini-type-expressions-matrixspec-lean-v1/runs/paln-r3/frozen-delta-spec.md#L19-L22" - "campaigns/pytest-addini-type-expressions-matrixspec-lean-v1/runs/paln-r3/frozen-delta-spec.md#L48-L54" - "packs/tasks/pytest-addini-type-expressions/task.json#L31-L43" - "campaigns/pytest-addini-type-expressions-matrixspec-lean-v1/runs/paln-r3/candidate-main-turn-01.jsonl#L88-L94" - "campaigns/pytest-addini-type-expressions-matrixspec-lean-v1/runs/paln-r3/focused-test-01.stdout.txt#L1-L6" - "campaigns/pytest-addini-type-expressions-matrixspec-lean-v1/runs/paln-r3/state.json" - "campaigns/pytest-addini-type-expressions-matrixspec-lean-v1/evaluation/results/judge-01/Candidate-A/judge.final.json" - "campaigns/pytest-addini-type-expressions-matrixspec-lean-v1/evaluation/results/judge-02/Candidate-A/judge.final.json" - "campaigns/pytest-addini-type-expressions-matrixspec-lean-v1/runs/paln-r1/focused-test-01.stdout.txt#L2-L16" - "campaigns/sqlmodel-field-constraints-matrixspec-lean-v1/runs/sln-r3/frozen-delta-spec.md#L20-L43" - "packs/tasks/sqlmodel-field-constraints/hooks/verify.ps1#L7-L22" status: user-confirmed-and-selected-for-H0601 confirmation: status: user-confirmed-through-H0601-authorization confirmedWeaknesses: - W-01 - W-02 note: >- The user explicitly selected both repair directions and authorized the H0601 successor.
