+# P0 execution report: 2026-10-28
+
+**Status: blocked by provider billing. No GO, PARTIAL or NO-GO decision.**
+The owner requested delivery of the fixes and this report now, with the remaining paid calls deferred.
+
+## What ran
+
+The owner explicitly authorized sending the 65 textbook passages and corresponding Lean code
+through the existing DashScope endpoint to `qwen-max`, at temperature 0 and a cumulative ceiling
+of 400 HTTP requests. The run issued **131 HTTP requests**. Provider responses accounted for
+**37,699 input tokens and 7,790 output tokens**, 45,489 total. These are recorded token counts,
+not an invoice or a monetary cost estimate. The client counted 89 received model responses;
+a received response is not necessarily a usable detector result.
+
+| Coverage | Count |
+|---|---:|
+| Original cohort | 65 |
+| Items with both detectors complete | 42 |
+| Items with one or both detectors missing | 23 |
+| Successful role-extraction/alignment components | 45 |
+| Successful judge components | 43 |
+| Missing role components | 20 |
+| Missing judge components | 22 |
+| Remaining request reservations | 269 |
+
+DashScope returned HTTP 400 with error code `Arrearage` and its overdue-payment reference.
+The first runner implementation recorded the failures and continued through the cohort, so
+65 saved rows did not mean 65 successful items. The scorer rejected these incomplete outputs.
+No partial-sample gate decision or performance comparison has been produced.
+
+## Inputs and labels
+
+The default `items.jsonl` export omitted `source_text`. All 65 original passages were recovered
+from the matching detection spans and checked byte-for-byte against the archived private
+`review.json`. Item IDs and Lean code were unchanged. The recovery tool also verifies every
+exported field against the archive, normalizing the archive's JSON-encoded imports field.
+Source-inclusive inputs and the regenerated labeling HTML remain in the ignored data directory.
+
+The owner replaced the planned Kimi/human labeling with Codex annotation. All 65 labels were
+frozen before the first detector request. They contain 30 faithful, 25 wrong, 7 minor drift and
+3 not-formalizable verdicts. This is one AI annotator, **not human gold**. The annotator saw the
+detector implementation and aggregate compilation counts, but not per-item compiler outcomes
+or detector outputs. Syntax/proof defects were ignored when the intended semantics were recoverable;
+no compiler or API-name audit was performed. Independent human auditing remains necessary before
+using these labels as evidence for paper-level claims.
+
+## Execution repairs
+
+- Empty passages and mismatched frozen inputs/labels are rejected before paid calls.
+- Each HTTP attempt reserves cumulative budget before sending, including transport and JSON retries.
+  Model, endpoint, temperature, input/label/prompt hashes and cumulative token usage are persisted.
+- Billing/authentication errors now stop immediately, preserving partial results.
+- Resume keeps every successful detector component and retries only missing components. Existing
+  rows are replaced atomically rather than duplicated. A budget stop also preserves completed work
+  within the current item. A lock prevents concurrent writers.
+- `--audit-only` reconciles saved metadata without API calls. It confirmed 42 complete items,
+  23 incomplete items, 42 missing components and 131 already-consumed request reservations.
+- Scoring requires complete results and unchanged frozen-label/result hashes. It restores the
+  preregistered complementary-signal PARTIAL rule and uses wrong versus faithful for primary metrics;
+  minor drift is included as positive only in the secondary comparison.
+- Detector prompts, matching thresholds, the concept table and frozen annotations were not tuned
+  against these outputs. Recovery changes concern transport, persistence and accounting only.
+
+The private first-attempt output and metadata were backed up before reconciliation. The results
+hash and the frozen-label hash did not change during the offline audit.
+
+## Validation and next action
+
+149 offline unit tests passed, including billing-stop and partial-resume regressions; repository-wide
+Ruff and diff checks passed. These checks did not compile Lean or build Docker locally.
+The initial PR revision passed Python tests and real Lean validation on
+`ubuntu24.04-x64-lean4.35`, runner 7, in [CI #427](https://gitea.entroia.com/Zayden-Jung/lean-bench/actions/runs/427).
+The image job was skipped by the PR workflow. The recovery revision passed [CI #433](https://gitea.entroia.com/Zayden-Jung/lean-bench/actions/runs/433).
+The recovery changes from PR #6 are consolidated with the semantic schema and review page
+in PR #9; the combined head is checked separately there.
+
+After the owner confirms billing recovery, resume the existing run with the same inputs, frozen
+labels and cumulative budget. There are 42 missing components; retries may consume more requests.
+Do not change model or prompts to work around the provider block. Only after all 65 items have
+successful outputs should the scorer produce the registered decision and disagreement report.
+Phase 1 has not started.

 Owner amendment (2026-10-28, in the execution chat): Codex now handles preparation,
 annotation, detector execution and reporting; Kimi's participation is no longer required.
