  "executiveSummary": [
    "The continuous queue is active, its circuit breaker is closed, and external discovery continues to refresh. The absence of a new promotion is not caused by a stopped scheduler.",
    "The live queue reports 230 ideas, 137 actionable records, 73 retrying records, one active candidate, three implemented outcomes, 42 rejected outcomes, and 17 artifact-blocked outcomes.",
    "The newest post-correction candidate demonstrated useful behavior by returning the correct arithmetic result, 17 × 24 = 408, but construction rejected it because the generated contract required at least 15 characters and the correct concise response contained 13.",
    "That candidate never reached public and held-out evaluation. This is direct evidence of a remaining construction-contract and repair-feedback defect rather than evidence that the proposed improvement lacked merit.",
    "A focused regression run passed 58 tests, showing that the queue controller and the recently corrected attribution machinery are internally consistent while leaving a semantic calibration gap in generated task contracts and candidate repairs."

        "Queried the live continuous-improvement API and confirmed one active candidate, a closed circuit breaker, ongoing retry activity, and continued external-source packet creation.",
        "The active worker is using repository revision 908cb83, the revision containing the corrected continuous approval evidence changes.",
        "The most recent scheduler messages continue to report completed ticks and three implemented outcomes, so the displayed lack of new promotions is not a dashboard-only consequence of a dead worker."

      "details": [
        "Separated the three implemented records from 31 evaluation rejections, four disproven canaries, one construction failure, six legacy rejections, and 17 currently artifact-blocked records.",
        "Two implemented records are user-authorized platform repairs. One record is a prior automatic Stage 5 promotion, so the dashboard's total of three implemented outcomes should not be interpreted as three new autonomous promotions.",
        "Recent valid evaluator rejections include held-out epistemics regression and excessive latency. Those are materially different from construction-stage failures and remain legitimate negative evidence."

        "The candidate-authored regression test then failed only because len(result) was 13 while the generated task contract specified minimum_characters 15.",
        "The candidate exhausted its construction repairs and was marked candidate_failed without receiving a baseline contrast, public evaluation, held-out evaluation, canary, or governor decision.",
        "Earlier attempts in the same packet also exposed repair-quality problems: one test invoked the model path and received an HTTP 400, and another called an asynchronous function without awaiting it. The final attempt fixed those issues but did not adapt to the remaining length-only failure."

      "details": [
        "Within the latest 100 queue events, five candidates exhausted repairs into artifact-blocked status and 25 more scheduled another candidate revision.",
        "Three of those five terminal artifact blocks were stale or ambiguous edit anchors in core/router.py. Another combined an ambiguous anchor with invalid local-agent JSON, and one baseline run raised a non-contract TypeError.",
        "The latest arithmetic case did apply its patch successfully, making the overly rigid test contract the immediate blocker rather than an edit-anchor failure."

  "decisions": [
    "Classify the current promotion drought as primarily a technical construction and contract-calibration problem, not as proof that the queue is failing to discover useful opportunities.",
    "Do not weaken public, held-out, latency, category-regression, safety, or canary gates based on this diagnosis; the demonstrated defect occurs before those gates.",
    "Treat correct concise answers as valid when they satisfy the semantic task contract, rather than imposing a generic minimum-character threshold that can contradict the intended behavior.",
    "Require candidate repair logic to consume the exact final failing assertion and verify that its next patch resolves that assertion before spending the last repair attempt.",
    "Continue reporting implemented, autonomously promoted, evaluation-rejected, hypothesis-disproven, and artifact-blocked outcomes separately."

    "No post-correction candidate observed in this session reached and passed the global approval evaluator.",
    "The newest completed construction run is positive evidence that the generator can create useful behavior, but the test-contract and repair layers can still discard that behavior before evaluation."
  ],
  "limitations": [
    "One decisive candidate autopsy proves that at least one useful change was blocked technically; it does not prove that every historical evaluation rejection was wrong.",
    "The focused regression suite verifies coded invariants, not the semantic reasonableness of every generated task contract.",
    "Candidate behavior was inspected in its isolated worktree. It was not promoted, merged, deployed, or exercised against production traffic.",
    "The queue remains throughput-limited by repeated edit-anchor failures, malformed agent output, baseline-incompatible tests, and repair attempts that do not always converge on the last failing assertion."
  ],
  "nextSteps": [
    "Replace generic response-length floors with task-type-specific semantic checks and explicitly allow concise exact answers for arithmetic and similarly bounded tasks.",
    "Add a preflight contract-consistency check that rejects an oracle whose required canonical answer cannot itself satisfy its length constraints.",
    "Make the repair prompt and validator carry the exact final assertion failure, observed output, and relevant contract field, then require a local proof that the named failure changed before accepting the repair attempt.",
    "Add deterministic patch templates for common entrypoints so stale or ambiguous source anchors do not consume model repair attempts.",
    "Track construction yield and evaluator yield separately on the benchmark page, including the percentage of candidates that actually reach public and held-out evaluation.",
    "After these construction fixes, replay retained artifact-blocked candidates and measure how many become valid evaluated candidates before drawing conclusions about idea quality."
