Status: NOT READY TO MERGE — experimental machinery stays here. Extracted so far: routing + cite-by-location → #118 (merged, released as v0.35.83); structured review publication (per-allegation results, code-assembled review, incomplete status) → #119 (open, for the merge decision). What remains only here: mandatory runtime classification, fidelity experiments, relevance flags and assertion-to-verdict derivation, with the red missing-directory regression preserved as a known limitation. Audit and plan: docs/review-pr117-audit-and-evaluation-plan.md.

Why

kai review-commit's publication challenge validated evidence by having the model reproduce excerpts byte-for-byte; one bad citation invalidated the whole review. The system already holds every source.

What changed

Structural gate: cite by location; structured per-allegation results; remedies gated by status (withheldRemedy otherwise); mandatory requires_runtime; decisions assessed from the draft; summary/incomplete derived from final results; readiness only ever capped; status carried through bundle incomplete + structured challenge record, CLI Status: INCOMPLETE, nonzero exit; one format-repair nudge, substantive failures never retried.

Evidence contract: review_shell fidelity mode executes the generated string unchanged and preserves the complete record of every attempt (completed vs not_run, each assertion's expected/observed). An experiment citation must connect to the allegation (addresses_allegation, covers_alleged_inputs, expectation, tested) and name the recorded assertion(s) it offers; the observation is derived from those only. Four rules: an observed violation can support; a passing example refutes only on the alleged inputs and never over an observed violation; an experiment that doesn't address the allegation leaves it unresolved; one that couldn't run supplies no conclusion. Verdicts are never flipped. Stated narrowly: the construction is model-authored, and relevance/coverage/expectation/selection are model judgment — recorded, not checkable.

Model separation (9a4a1ff): the fast path drafts with a substituted non-reasoning model but the challenge now uses the configured review model; each bundle records per-phase configured / requested / upstream provider (served model left unknown to the process). Regression TestFastDraftDoesNotSubstituteChallenger. The submission schema now requires decisions, matching the validator.

Evidence

  • Deterministic (container): the actual #429 statement, vendored verbatim, is misdirected for $, $(…), backtick and correct for space/quotes; forensic replays pin the earlier wrong-verdict mechanism.

  • Correction: every e2e row before 9a4a1ff — including the preserved wrong-verdict run — was challenged by Haiku, because the fast path handed the challenge its substituted draft model. Only the unit-specimen live tests were GLM.

  • 9a4a1ff, three fully captured CLI→bundle→render attempts, GLM-5.2 confirmed as challenger from response metadata (model: z-ai/glm-5.2; DeepInfra/StreamLake):

    • Completion 3/3 (one incomplete); no timeouts, no rejections.
    • Confirmed defects 0/3.
    • Missed defects 3/3 — draft alleged the defect 1/3 (attempt 2); twice by draft omission (the Haiku draft never alleged the quoting defect; challenger not exercised; review published "4/5 — your call, then merge"), once by the challenger (defect class alleged and reproduced — exit 2, pwd /tmp — but GLM supplied none of the relevance fields, so the gate correctly left it unresolved).
    • Incorrect verdicts 0/3 — two correct refutations of false guard allegations.
    • All three bundles render correctly through the real server path.
  • 9a4a1ff, deep path (--deep), GLM-5.2 drafting and challenging (both confirmed from response metadata for every answered call; one cancelled-and-resent conclusion request left "unknown"), same captured snapshot b8f5add6821e for all three attempts (store bytes differ per attempt — run bookkeeping only; documented):

    • Completion 0/3 — bundles emitted 3/3, every one incomplete (host-dependent allegations left unresolved), exit 1; no timeouts, no rejections; one format-repair nudge (attempt 1).
    • Draft detection 3/3 — every deep draft alleged the JSON.stringify quoting defect.
    • Confirmed defects 3/3 — the challenger supported it each time with model-supplied relevance fields; verdicts correct, but attempt 1 rested on one of two citations (the other asserted command text in stdout) and attempt 2 on one of three (two mislabelled real misdirection as conformance). Only attempt 3's citations were all well-formed.
    • Incorrect verdicts 1/3 (corrected from 0/3): attempt 3 also published, as a confirmed finding, that cd … && "silently aborts" when the workspace is missing — the requirement's own behavior for that case, "silently" contradicted by the record's stderr, with a remedy (cd … ;) that would run the command in the wrong directory. Rendered: "did not finish… treat as not reviewed" banner, readiness 3/2/2.
    • Fast→deep draft detection (1/3→3/3) is confounded: model and workflow changed (harness with tool access, intent step, conclusion fallback authored every deep draft). Differences are tabulated in the record.
  • Review of the deep captures (no new runs): 3 of 5 unresolved allegations are host-contract limitations the repo can never resolve — the deep prompt (review_commit.go:64) orders out-of-reach dependencies to be filed as findings and the REVIEW-DATA coda has no limitations slot, so they become allegations and every such review is incomplete by construction. The other 2 are gate downgrades of mislabelled evidence. Evidence trace: observation() reads only offered pass/fail + the expectation label; an assertion that can never pass (command text in stdout) counted as a violation, and reversed labels turned real misdirection into "conformance" — the verdict survived on one sound citation each time; the reversal under a refuted verdict is still the old false-negative path. Chosen smallest change (not implemented): a draft LIMITATIONS coda slot for out-of-reach dependencies, carried verbatim into the published review, never an allegation. It fixes completion, not the incorrect-verdict or evidence findings — stated in the record.

  • Missing-directory case preserved as a RED regression (testdata/pr429/deep-attempt3-missing-dir.json, review_commit_missingdir_test.go): the challenger's exact inputs and submission; TestStoppingAfterFailedCdIsNotPublishedAsADefect fails by design until behavior is assessed against the requirement; fixture-identity and quoting-verdict guards are green. Limitations-to-complete: not adopted.

  • Proposal (not implemented), corrected after two counterexamples: the old/new-shape rule (regression-shaped → decision) would demote a genuine regression, and the remedy-equality rule would refuse a valid fix that restores the previous outcome — both withdrawn; old/new runs are observations, not desirability. Kept: system-side source classing (author context = requirement; the intent reconstruction laundered the author's "safely quoted" claim and is not requirement-class); a runtime verdict must state the requirement's expected behavior for the tested input and cite the requirement-class clause, with the offered assertions as that statement made testable; a remedy is a correction only if executed and the same requirement-derived assertions pass, else a suggestion; stderr_* assertion kinds; clause + expected + observed + stderr published with every finding and remedy. Experiment budget unchanged. Requirement interpretation stays model judgment, named as such — evaluated directly against "the command must not execute in the wrong directory", the original cd && conforms (does not execute; stderr says why) and the cd … ; remedy violates it (runs in /tmp); with a faithful statement the red regression's acceptance holds, with an unfaithful one the contradiction is published on the page, not caught.

  • Display-only rendering of the bad submission (in the record): with the evidence block added and the gate frozen, the page still says "2 confirmed findings", "needs work", keeps the "silently aborts" headline two lines above the stderr that refutes it, and keeps cd … ; under Remedy (relabelled unverified); Atlas sees none of the block. Decision: the intended outcome is prevention, not inspectability — the acceptance test says "not published as a confirmed defect". Candidates recorded, not implemented: (1) a supported runtime verdict with no requirement-anchored expectation → unresolved; (2) confirm observations, not defects — runtime findings published as observed behavior + the challenger's reading + your call, not counted as confirmed defects, remedies as suggestions (redefines "confirmed" for the class; the true quoting defect gets the same label). Regression stays red.

  • Independent adjudication pass (testdata/pr429/adjudication/, throwaway harness, gate untouched): fresh GLM-5.2 given requirement + diff + recorded executions (incl. pre-change code and the remedy executed) + allegation + remedy, prior verdict/readiness withheld, violation and remedy asked separately, 4 cases × 3 attempts, every call preserved, model confirmed. Valid findings and fixes retained 9/9 (quoting defect; genuine regression whose fix restores the pre-change outcome; requirement-flipped control accepting cd … ; — it reads the requirement, not the pattern). Harmful cd … ; remedy rejected 2/3, endorsed 1/3; the false violation was never adjudicated "conforms" (0/3) — the same model read "cd into the workspace before running the command" three different ways on identical evidence. A second judgment does not reliably prevent the false finding; the disagreement is in requirement reading, not evidence.

  • Case 5 — same case, one clarification added to the requirement ("If the workspace cannot be entered, do not execute the command in another directory; report the failure."), everything else identical, 3 attempts preserved: cd … ; remedy rejected 3/3 for the right reason, citing its recorded run. Violation label "violation" 3/3 — but attempts 1 and 3's reasoning concludes the code conforms (one literally says "Wait — re-evaluating … it conforms") with the structured field left as violation; attempt 2 reads "report the failure" as an application-level report the shell's stderr does not satisfy. Acceptance half met: harmful correction not published; false defect still labelled a violation. Second instance in this record of a model's structured field inverting its own correct prose.

Not done / open

Original #418 false positive unexplained. Expectation interpretation deliberately unchanged (a prior run misdeclared direction and lost a reproduced defect). The draft's failure to allege the known defect dominates effectiveness and is outside the challenger. Atlas rendering of the structured record, partial-review headline wording, and Stage 2 are separate.

🤖 Generated with Claude Code

The publication challenge validated each finding's evidence by asking the
model to reproduce a source excerpt byte-for-byte, then substring-matching it
against the stored source. Publication depended on copying accuracy, not just
reasoning: a whitespace, escaping, or source-number slip failed validation, and
one bad citation invalidated the entire review. A single bounded correction did
not close the gap — a second citation failing in the corrected answer withheld
the whole draft.

Cite by location instead. Each source is shown with numbered lines; a citation
is a source number and a line range, and the system extracts those exact lines
itself. The reviewer already holds the source, so no finding depends on the
model re-typing it.

Judge each allegation on its own evidence:
- An out-of-range/out-of-bounds citation is dropped and logged — it costs that
  one citation, never the review.
- A supported/refuted verdict with no usable citation is downgraded to
  unverified rather than failing the run.
- A runtime allegation (behavior source inspection cannot establish) must be
  backed by a successful review_shell experiment; the condition is whether the
  claim needs runtime evidence, not whether a sandbox is configured. Without the
  experiment it stays unverified — missing evidence is never license to
  substitute reasoning.
- Unverified allegations no longer withhold the review: independently supported
  findings publish, each unresolved allegation is preserved and listed, and the
  review is marked incomplete with MERGE_READY capped.

Structural failures still fail closed (malformed response, unknown/duplicate/
missing check, a revised review that drops a supported finding or reintroduces a
refuted one). The one-shot citation-correction loop is removed: cite-by-location
plus per-finding tolerance makes it unnecessary.

…tput, mandatory runtime flag

Three gaps from the review of the cite-by-location change:

1. "Incomplete" was prose-only. The challenge returned success and only wrote a
   warning into the body, so Atlas/CI read a partial review as completed.
   rcChallengeReview now returns the unresolved allegations; rcRunReviewAgent
   carries them on rcIncomplete.Unresolved and the fast path returns them too.
   runReviewCommit sets the bundle's `incomplete` flag and exits non-zero
   whenever anything is unresolved, while still publishing the supported
   findings.

2. Downgraded/refuted claims could survive in the surrounding prose and summary.
   The published review is now ASSEMBLED by the system from the validated
   results — the challenger returns structured fields (assessment, per-supported
   finding text, intent_match, merge_ready, summary, decisions) and the system
   builds the prose and coda. Only supported findings become defect prose, so a
   refuted or unresolved allegation cannot appear as a confident description or
   recommended fix. Replaces the earlier bullet-stripping approach.

3. requires_runtime was optional and defaulted to false, letting a model skip
   the classification to dodge the experiment requirement. It is now a mandatory
   per-check field (*bool); a missing classification fails the challenge closed,
   for structured and plain-JSON responses alike.

…reasons

Follow-up to the review of bc4470e.

- The model-authored review-level text (assessment, summary, decisions) could
  still assert an allegation the challenge did not support — a rejected claim
  surviving as a confident statement even though its per-finding section was
  gone. rcValidateChallenge now fails closed if the assessment, summary, or any
  decision contains a non-supported allegation verbatim. Per-finding defect prose
  was already system-sourced from supported checks only.

- The incomplete banner described every unresolved claim as missing a runtime
  sandbox, even one downgraded for an invalid citation. Each unresolved
  allegation now carries its actual reason (no usable citation / requires a
  runtime experiment / the model's own reason for an unverified verdict), and the
  banner prints it per claim. The outer diagnostic no longer hardcodes "runtime".

Regression tests: summary/assessment/decision asserting a non-supported finding
fails closed; the incomplete banner reports the correct, distinct reason for a
citation-invalid vs a runtime-unbacked downgrade.

Kai review

Kai Summary

Read through this one. 2 things worth your eyes before it merges, plus 1 decision to say yes to. 👇

Where I'd land: 3/5 — small fixes first.

Cite-by-location, per-finding tolerance, and incomplete-but-published plumbing are sound and well-tested, but the leakage guard that is this change's stated capstone misses the model-authored per-finding finding text, so a refuted or unresolved allegation can still reach the published review verbatim.

Decisions

Correct as written, but somebody should say yes to these:

  • An all-unresolved review caps MERGE_READY at 4 ("decide then merge"); every reviewer consumer (Atlas/CI badge, inbox, PR comment) will read a review that settled nothing as a soft yes, mitigated only by the incomplete banner and non-zero exit.

Full read-through

Scope: kaicontext/kai-cli, revision 3d584eb (review: finish gap 2…). I read cmd/kai/review_commit_challenge.go, the fast and deep review paths in review_commit.go and review_commit_fast.go, the full test suites in review_commit_challenge_test.go and review_commit_citation_test.go, and docs/review-evidence.md. I could not read the finding package — it lives in the kai-engine module, not in this repo's tree — so I inferred Readiness/Match ordering and the Valid() bound from usage and tests; that boundary is named where it matters.

What this does: It replaces the byte-for-byte citation-reproduction gate with cite-by-location ({source, line_start, line_end} the system extracts), makes each allegation fail or succeed on its own evidence, downgrades un-citeable or un-experimented runtime claims to "unverified" instead of failing the whole review, assembles the published review from validated structured fields, marks a review with unresolved allegations as incomplete (non-zero exit, capped MERGE_READY), and threads an unresolved []string up through both the fast and deep paths to runReviewCommit. The one-shot citation-correction retry is removed. The new return value is threaded consistently through every call site, and the removed symbols (rcValidateOrRepairCitation, rcCitationError) have no remaining references in the repo. The doc matches the implemented behavior.

Confirmed defects

rcAssembleReview publishes the model-authored finding text verbatim, but the leakage guard doesn't scan it (review_commit_challenge.go:367-377, 420). The INTENT states the gate "must not let a rejected or unresolved allegation leak into the published review through model-authored free text," and the system prompt at line 41 instructs the model that "finding" is "for a SUPPORTED verdict only: the published defect description and recommended fix." A supported finding's finding field is model-authored free text, published verbatim under ### {issue} (line 420), and a model can name a refuted or unresolved allegation inside it — e.g. finding A's prose reads "Unlike {issue B} which was also a defect, …" where B was refuted or downgraded. The guard at lines 368-377 only scans answer.Assessment, answer.Summary, and answer.Decisions; it skips the finding text of kept issues (the continue at line 370). So a non-supported allegation can still reach the published review as confident prose, which is what the change set out to prevent. This is a real defect in the core behavior the change is about, and it's local to fix — extend the freeText scan to include each supported finding's finding text checked against the other issues (every non-kept issue, not the one the finding belongs to), and fail closed on a verbatim hit.

The refuted→unverified downgrade direction is not directly tested (review_commit_citation_test.go:107-140). The PR description promises "both directions" for TestReviewChallengeRuntimeClaimNeedsExperiment, but the test only exercises the supported verdict (with and without an experiment). The refuted runtime claim shares the same downgrade branch (review_commit_challenge.go:336-344, the else covering both supported and refuted), so it works today, but the system prompt explicitly requires ("A 'requires_runtime' verdict of 'supported' or 'refuted' must be backed by a successful review_shell experiment") the refuted-runtime-claim-without-experiment downgrade, and there is no test that would fail if that shared branch were accidentally narrowed to supported only. No test in the suite combines Verdict: "refuted" with RequiresRuntime: truercCDChecks uses refuted with rcBool(false), and TestReviewChallengeIncompleteBannerGivesPerClaimReason uses supported with rcBool(true). A single additional test case with a refuted verdict, requires_runtime: true, a valid citation, and no experiment would guard this branch.

Design judgment (not a defect)

An all-unresolved review caps MERGE_READY at 4 ("decide then merge"), which reads as a soft green for a review that established nothing (review_commit_challenge.go:381-389). When every allegation is unresolved (len(kept) == 0, len(unresolved) > 0), there are zero supported findings yet the review still publishes readiness 4. TestReviewChallengeUnverifiedThroughProvider and TestFastReviewReportsUnresolved both confirm this: MergeReady: 4, all-unverified, marked incomplete. The incomplete banner and non-zero exit mitigate it, and the "decide for yourself" score is a defensible design choice — it is a judgment call about how a review that settled nothing should read downstream, not a mechanical consequence of the per-finding logic.

Limitations of this review

I could not read the finding package source (it is in the kai-engine Go module, outside this repo's tree), so the correctness of the readiness-coherence comparisons at review_commit_challenge.go:381-389 rests on Readiness being an ordered numeric type where ReadinessUnknown is outside the valid 1-5 range (so readiness.Valid() rejects it at line 295, and the >/< comparisons against ReadinessSmallFixes(3) and ReadinessDecideThenMerge(4) behave as the test expectations imply). If ReadinessUnknown compared as a low-but-valid value, the all-unresolved cap could behave differently; the tests do not contradict the assumed ordering, but I did not confirm it from the type definition.

Notes on what's solid

The unresolved []string plumbing is consistent end to end: rcChallengeReviewrcRunFastReview/rcRunReviewAgent (inc.Unresolved) → runReviewCommit (line 412 sets incomplete = true, lines 549/563 return rcErrIncompleteReview for non-zero exit). TestFastReviewReportsUnresolved verifies the fast path surfaces unresolved and marks the body incomplete; TestReviewChallengeUnverifiedThroughProvider does the same for the deep path. The deep-path salvage branch (review_commit.go:398-407) does not double-fire when unresolved is non-empty, because the assembled review always carries prose, a known match, and kept risks. Per-citation tolerance (review_commit_challenge.go:316-328) drops one out-of-bounds citation and logs it without failing the review, as the doc states. The mandatory requires_runtime classification (line 313) and the "supported needs a finding" check (line 348) fail closed, and TestReviewChallengeFailsClosed covers both plus the unknown-verdict, unknown-issue, duplicate, and bad-readiness cases. The experiment map correctly tracks which appended source numbers are review_shell results, and source numbering stays stable across turns. Removed symbols have no dangling callers. docs/review-evidence.md matches the code — assembled output, cite-by-location, per-citation tolerance, mandatory runtime classification, incomplete-as-bundle-state, and the three-minute ceiling.

Merge readiness: the leakage-guard gap is a real defect in the core behavior the change is about (preventing non-supported allegations from reaching the published review), and it's local to fix. The missing test coverage for the refuted-runtime-claim direction is a test gap, not a code defect. With the leakage guard addressed this is ready.

TestReviewChallengeRuntimeClaimNeedsExperiment only covers the supported direction; the refuted-runtime-claim-without-experiment downgrade has no test that fails if the shared branch is narrowed.

…limitations

The previous guard only caught a non-supported allegation repeated verbatim. A
paraphrase ("Multiline commands execute in the wrong directory." for a refuted
"later lines run outside the workspace after a successful cd") passed it. String
matching cannot establish semantic consistency, so stop relying on it.

Remove the free-form fields instead. The challenger's contract now has:
- no assessment field: review-level prose is a structured scope list and a
  structured limitations list, which describe coverage, not outcomes;
- no summary field: the coda SUMMARY is derived by the system from the final
  supported/refuted/unresolved counts and statuses (rcDeriveSummary);
- decisions preserved explicitly as a separate list, in both the prose and the
  DECISIONS coda.

Every allegation's outcome is expressed only through its check, and a refuted or
unresolved allegation gets no section and no place in the summary. A stray
"summary"/"assessment" key from the model is unknown to the struct and is
discarded. The verbatim substring guard is deleted.

Stated precisely (the earlier "fully system-controlled" overstated it): the
system controls structure and selection — which allegations get a section, and
what the summary and coda say. The text inside a supported finding's section,
and the scope/limitations/decision items, remains model-authored.

Regressions: the reviewer's paraphrase specimen is discarded and the published
SUMMARY is the derived one; a refuted allegation surfaces nowhere; decisions are
preserved (blanks dropped); per-claim unresolved reasons still distinguish a
citation-invalid downgrade from a runtime-unbacked one.

…decisions assessed

Close the review-publication gap end to end.

1. Every allegation's final result is structured data (rcAllegationResult):
   id, supported/refuted/unresolved status, validated evidence references
   (each marked whether it is an experiment from this challenge), the
   unresolved reason, and any proposed remedy.

2. Remedies attach to allegation ids. A remedy is published as actionable only
   when its allegation is supported; a fix proposed for a non-supported
   allegation is recorded as withheldRemedy and never published as advice.

3. The unrestricted "Decisions" path is gone. The challenger cannot introduce
   a decision; it can only assess the decisions the DRAFT made, each with a
   verdict and a citation, like an allegation. A decision the draft never
   made is dropped and logged; a draft decision left unassessed fails closed.
   A different heading can no longer carry repair advice around the evidence
   requirement. Genuine draft decisions are preserved when supported.

4. Summary and incomplete status are generated from the final results.
   Supported findings are preserved when others remain unresolved. The status
   travels: the bundle carries the incomplete flag and the full structured
   challenge record; text-mode CLI prints an explicit Status: INCOMPLETE
   line; the run exits non-zero.

5. The log records the FINAL validated verdict, including any downgrade —
   not the verdict the model submitted.

Live evaluation caught a real defect: with no sandbox, the model asks for
review_shell anyway, and treating that as fatal withheld every finding. It is
now answered with an error tool result and the challenge continues; the
initial message also states no sandbox is available. The 4-call cap bounds
any loop; a genuinely unknown tool remains fatal.

Regressions from the observed failures: an unresolved cd allegation cannot
publish brace-wrapping advice under Decisions; a model claiming an absent
experiment (phantom source, or a non-experiment source with a runtime
verdict) is downgraded and its remedy withheld; one invalid citation leaves
only that finding unresolved while a supported one remains; partial results
reach the emitted bundle as incomplete with the structured record attached.

Live #418 and #429 evaluations (anthropic/claude-opus-5) pass in all four
configurations: with a digest-pinned alpine sandbox the false cd is refuted
and the escaping and JSON.stringify defects are supported via experiments
with remedies actionable; without a sandbox every runtime claim is
unresolved, the review incomplete, and remedies withheld. Limitation: the
alpine sandbox has no JS runtime, so in #429 the claim that JSON.stringify
leaves $ unescaped rested on the source comment plus shell semantics rather
than an observed JSON.stringify call — the model reported this itself.

…e correcting

Record, not a fix. docs/review-evidence-glm-runs.md preserves each GLM-5.2
attempt on #418 with the Node sandbox, its exact failure output, what was not
captured, and the revision made in reaction — so later outcomes are judged
against what happened, not against a final passing run.

Code in this commit is the state reached through those reactions:
- R1: readiness coherence fail-closed → clamp. As written this includes a
  RAISE clause that makes a contradictory answer more permissive; it is
  wrong and is corrected in the next commit.
- R2: embedded-JSON extraction; one bounded "call submit_review" nudge under
  the original deadline with tools restricted to submit_review; full
  revalidation afterward.
- R3: log malformed final-answer head and each experiment's output.
- R4: prompt states an experiment counts only if its numbered source is
  cited. UNTESTED at this commit.

Without-sandbox #418/#429 and with-sandbox #429 passed on first attempt with
no code change. With-sandbox #418 failed on attempts 1, 2, and 3 (readiness
contradiction; prose final answer; no experiment cited). See the record.

Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>
…t answers

Corrections to R1 and R2 (see docs/review-evidence-glm-runs.md):

- Readiness is only ever CAPPED from the final statuses, never raised. R1's
  clamp had a clause that raised a cautious score to decide-then-merge —
  turning a contradictory answer into a more permissive recommendation. It
  is removed. A confirmed defect caps at small-fixes; an open decision or an
  unresolved claim caps at decide-then-merge; a score lower than the results
  would justify is left alone.

- A final answer containing more than one decodable top-level JSON object —
  even with prose between them — is an ambiguity and is not treated as a
  submission; the gate does not guess which answer the model intended. A
  single object with trailing prose is still a submission.

The single format-repair nudge is unchanged: original deadline, no new
evidence, tools restricted to submit_review, full revalidation afterward.

…ic failures never retried

Revision R5, reacting to the preserved end-to-end GLM-5.2 run in which the
submit_review payload carried "checks" as a JSON string and the gate failed
closed with no bundle.

An unparseable payload is a FORMAT failure (errRCMalformedAnswer). It earns
the single format-repair nudge already used for a prose non-submission: the
exact parse error is fed back as an error tool result, under the original
context deadline, with tools restricted to submit_review and no new evidence;
the resubmission is fully revalidated. The budget is one nudge total across
both forms. A payload that parses but fails validation (unknown issue,
missing check, bad verdict…) is substantive and is never retried. The
malformed payload's head is now logged so the next such run is diagnosable.

…ith expected results

Replays GLM-5.2's own experiments from e2e R5 attempt 3 in the real Node
container and pins what each actually shows: its hand-escaped cd tests succeed
because they tested an escaped literal (construction error); its JSON.stringify
printout shows $/backtick unescaped (sound experiment, misread); the corrected
variant with real JSON.stringify output misdirects the cd and fails (the defect
reproduces); double quotes do not suppress expansion (its stated shell fact
was wrong). No gate change.

Replaces the "all assertions passed" citation rule, which could discard
evidence of a defect and let a passing example on an irrelevant input support
a wrong conclusion (docs/review-evidence-glm-runs.md).

An experiment citation now carries the model's connection to the allegation:
addresses_allegation, covers_alleged_inputs, expectation ("intended" if the
assertions encode the intended behavior, "defect" if they encode the alleged
defect), and tested. The gate DERIVES the observation from the record rather
than trusting the conclusion: an intended-behavior assertion that failed, or a
defect assertion that passed, is the alleged violation observed; the converse
is conformance for the input tested. Four rules follow, and a verdict is never
flipped — one the observations do not carry becomes unresolved with the
reason recorded:
  1. an observed violation by a relevant experiment can SUPPORT the defect;
  2. a passing example establishes behavior for that example only — it can
     REFUTE only if it covered the alleged inputs, and never when a relevant
     experiment observed the violation;
  3. an experiment that does not address the allegation, or was never
     connected to it, leaves it unresolved;
  4. an experiment that could not run supplies no runtime conclusion.

The relevance and coverage bits remain model judgment; the fields make the
claim explicit and auditable in the bundle. No formatting retries added.

Validated against the PRESERVED wrong-verdict run: the fixture in
testdata/pr429/wrong-verdict-run.json was extracted from that run's bundle by
script. Its cited experiment (a double quote, all assertions passed) observed
conformance and did not cover the alleged inputs, so under these rules it can
neither support nor refute the allegation; GLM's actual "supported" verdict
becomes unresolved and its "no code change needed" remedy is withheld, with
or without an honest covers flag. The one remaining path to the wrong
conclusion is a false coverage declaration, which is recorded on the
citation rather than hidden.

…ize the unrelated-assertion gap; record 0/3 GLM bundles

Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>
…g rejected payloads

Assertion-selection bug (demonstrated in the preserved characterization):
under expectation "intended" the observation was derived from ANY failed
assertion, so an unrelated failure could establish support. Each experiment
citation now names, by number, the recorded assertion(s) it offers as evidence
for that allegation; the observation is derived from those only; the others
are preserved on the record but do not count for this allegation. A citation
that offers none, or one that does not exist, yields no observation. What was
offered is recorded on the citation (assertionsOffered). The rendered source
numbers its assertions so the model can reference them.

Regression: TestUnrelatedFailedAssertionCannotSupportDirectoryAllegation —
directory equality passes, an unrelated stdout check fails, the directory
assertion is offered: not supported; the failed assertion is preserved;
offering the unrelated assertion is recorded and visible.

Diagnosis of the three live failures from their full logs (record in
docs/review-evidence-glm-runs.md): attempt 2 was a model response failure
against the tool contract (construct mode misused, then a fifth call over the
cap), fully determinable; attempts 1 and 3 were validator rejections whose
rejected values were never logged — a diagnosability failure, not a protocol
conclusion. No retry added; no validation loosened.

Diagnosability only: the validator now logs a rejected submission payload in
full on any structural rejection, and the conflated "omitted reasoning,
duplicated a check, or checked an unknown issue" message is split into three
that name the offending value (likewise for decisions).

… the fast-path challenger was Haiku, not GLM

Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>
…s per phase; require decisions in the schema

Captured live requests showed every fast-path CHALLENGE call going to the
model substituted for the DRAFT (a non-reasoning stand-in for a reasoning
review model), because rcRunFastReview received one model and passed it on.
The publication gate must use the configured review model regardless of what
the one-call skim was drafted with.

- rcRunFastReview takes the draft model and the challenge model separately;
  runReviewCommit passes the substituted fast model for the draft and the
  configured review model for the challenge, and logs both.
- Each result records, per phase (draft, challenge): configured, requested,
  and the upstream provider when the gateway reports it. The SERVED model is
  not exposed by the provider layer and is left empty (unknown); a request
  proves only what was asked for, and effective is confirmed only from
  response/provider metadata.
- Regression: TestFastDraftDoesNotSubstituteChallenger — the draft is
  requested from the fast substitute, every challenge request carries the
  review model, and both phases are recorded.
- The submission schema now requires "decisions" (an empty array when the
  draft has none), matching what the validator enforces; the prompt says so.
  A live rejection came from exactly this schema/validator mismatch.

Expectation interpretation is unchanged. No retries added; deadline unchanged.

The fixture is deep attempt 3's exact challenger inputs and submission.
TestStoppingAfterFailedCdIsNotPublishedAsADefect is the acceptance
condition and fails today by design; the fixture-identity and
quoting-verdict guards are green. The proposal (source classing,
regression shape by executing the pre-change construction, executed
remedies refused when they reproduce the pre-change outcome, stderr
assertions) is recorded with what is mechanical vs judgment; its
mechanical checks were executed in the sandbox image on the case's

Kai review

Kai Summary

Read through this one. 2 things worth your eyes before it merges, plus 1 decision to say yes to. 👇

Where I'd land: 3/5 — small fixes first.

The gate overhaul is structurally sound and well-tested, but the decisions coda/record split and the decision-unresolved-counts-as-incomplete path are local defects worth fixing before merge.

Decisions

Correct as written, but somebody should say yes to these:

  • The readiness cap makes any unresolved allegation — including host-contract limitations the repo can never resolve — cap merge-ready at 4 and mark the review incomplete; this affects every deep review of a change with an out-of-reach dependency, which the author's own evidence shows is common, and is a policy tradeoff worth a human's yes.

Full read-through

I have enough to write the review. Let me verify one final concern — whether the published DECISIONS coda in the assembled review only carries supported decisions while the bundle's structured Decisions carries all of them, which could create an inconsistency between what Atlas/CI parse and what the coda says. I've confirmed the structure from the code I've read.

Review

I reviewed kaicontext/kai-cli at revision 9a4a1ff — the review-commit publication gate overhaul (cmd/kai/review_commit.go, cmd/kai/review_commit_challenge.go, cmd/kai/review_commit_fast.go, cmd/kai/review_commit_sandbox.go, and their tests). I could read everything the change touches inside this repo; the model/provider behavior the author cites (GLM-5.2 latencies, served-model metadata) is outside this repo and I did not re-verify it.

The change replaces a free-form "reproduce the excerpt byte-for-byte" challenge with location-based citation extraction, structured per-allegation results, system-derived experiment observations, mandatory decision assessment, conservative readiness capping, and a structured rcChallengeResult that travels in the bundle. It also fixes the fast path so the draft-model substitution never reaches the challenge phase. The design is sound and the test coverage is genuinely aimed at the observed failures (the four verdict rules, the absent-experiment downgrade, the unavailable-sandbox-is-not-fatal case, the single-nudge format repair). I found two real defects and one decision worth surfacing.

Concerns

1. rcAssembleReview publishes only supported decisions in the DECISIONS: coda, but the bundle's structured Decisions carries refuted and unresolved ones too — and rcParseReviewOutput re-parses the coda. (cmd/kai/review_commit_challenge.go:951-963 vs :764-769, :800)

The coda's DECISIONS: section is built from keptDecisions (supported only). But res.Decisions on the rcChallengeResult — which is what the bundle's challenge field carries for Atlas/CI — contains every draft decision with its final status (supported/refuted/unresolved). So the published text a human reads lists only the decisions that need a human's call, while the machine record carries the full assessment. That split is arguably intentional (a refuted decision needs no call), but it creates a real inconsistency: downstream code that ingests the review (runReviewCommit calls rcParseReviewOutput(raw) at review_commit.go:382 to get decisions for the bundle's top-level fields) will see only the supported decisions in raw, because raw = res.Review and the coda only lists supported ones. So the bundle gets two different views of decisions — the parsed-coda decisions (supported only) and challenge.Decisions (all). If any consumer keys off the parsed decisions rather than challenge.Decisions, a refuted decision silently vanishes from their view. The fix is to be deliberate about which is canonical: either document that the coda's DECISIONS: is "decisions needing your call" only (and ensure all consumers read challenge.Decisions for the full record), or emit the full set in the coda. Given the author's stated goal that "Atlas and CI read the same verdicts the gate decided," the current split works against that for decisions.

2. A draft decision assessed unverified with no citation becomes unresolved, which sets Incomplete and caps readiness — but the decision assessment has no requires_runtime gate, so a non-runtime decision that merely lacked a citation is treated identically to a runtime one. (cmd/kai/review_commit_challenge.go:734-745)

For allegations, the runtime path (*check.RequiresRuntime) is what triggers the experiment-relevance checks; a non-runtime allegation with no citation is downgraded to unresolved at line 677, which is correct. For decisions, there is no requires_runtime field and no experiment-relevance logic at all — line 734 calls rcResolveCitations but discards the rel (second return) entirely, and lines 735-740 only handle the empty-refs and unverified cases. So a decision that the challenger left unverified (or cited nothing usable) becomes unresolved, contributing to len(unresolved) at line 755 and thus Incomplete and the readiness cap at line 783. That is conservative and probably fine, but it means a draft decision the challenger simply couldn't be bothered to cite (a non-runtime judgment call) marks the whole review incomplete and drops merge-ready to ≤4, exactly as a genuinely unsettled runtime allegation would. The author should confirm that's the intended behavior — the comment at line 770 frames "unresolved" as an unsettled claim, and a decision is not a claim of runtime behavior. If a decision can be a "genuine design choice present in the change" that the challenger supports on reading alone, then withholding-citation should not necessarily make the review incomplete. At minimum, decisions that downgrade to unresolved for lack of citation should not count toward Incomplete the same way; or the decision path needs the same requires_runtime distinction.

3. (Decision) The readiness cap makes "any unresolved allegation" cap merge-ready at 4 — so a single unsettled low-stakes allegation on an otherwise clean change can never publish a 5, and the fast path's own ceiling already caps at 4. (review_commit_challenge.go:783-785)

This is the author's call, not a defect: the cap is conservative and only ever lowers. But note the interaction: an unresolved allegation that is a host-contract limitation (the author's own evidence notes 3 of 5 deep-path unresolveds are things the repo can never resolve) forces Incomplete and readiness ≤4 on every deep review of such a change. The author already flags this in their context. The consequence is that deep reviews of changes with any out-of-reach dependency will be incomplete-by-construction and never read as clean merges. That is a policy decision worth a human's yes — it trades "never over-claim completeness" for "deep reviews are almost always incomplete on real-world changes." Name it; don't weigh it.

What's done well

The verdict-rules logic in rcResolveCitations / observation correctly ties the verdict to what was observed rather than what the model guessed, and the four rules are each covered by a dedicated test case in TestReviewChallengeVerdictConnectsTestedAndObserved that would fail if the rule were inverted. The notRun experiments being preserved on the record with Source: 0 (so they can't be cited as evidence) is a clean touch. The format-vs-substantive nudge split is exactly right: a parse error gets one repair, a validation rejection never does, and both are tested. The fast-path model separation is pinned by TestFastDraftDoesNotSubstituteChallenger, which checks the per-phase Requested/Provider record — that test would fail if the challenge request went to the draft substitute.

Bottom line

Two real but local defects — a decisions-canonical-view split and the decision-unresolved-counts-as-incomplete path — both fixable in the validator/assembly without touching the core gate. The design is sound and the regression tests are aimed at the right things.

…e by location (#118)

Two independent fixes extracted from the cite-by-location work (#117), on
top of main:

Routing. The fast pass may substitute a non-reasoning draft model
(KAI_FAST_MODEL / rcFastModel); that substitute was also handed to the
publication challenge, so every fast-path challenge ran on the draft
substitute instead of the configured review model. rcRunFastReview now
takes the challenge model separately; the caller passes the configured
model; the run logs which model was requested for each phase. Regression:
TestFastDraftDoesNotSubstituteChallenger.

Citations by location. The challenger cites a source number and a
one-based line range; every source is shown with numbered lines and the
system copies the cited lines itself. This removes the requirement that
the model reproduce an excerpt byte-for-byte — the failure that withheld
whole reviews over a mis-copied quotation. A location that does not exist
(unknown source, range before line 1, reversed, past the last line) still
fails validation with a precise diagnostic and keeps the base's single
bounded correction. It does not check that the cited lines support the
claim; review accuracy is not established by this change. Regressions:
TestReviewCitationIsExtractedBySystem, TestReviewCitationDiagnostics,
TestReviewCitationCorrection (adapted to locations).

Everything else in the base is unchanged: the model still writes the
revised review, an unverified allegation still withholds the review,
review_shell is script-only, deadlines are the base's.

Kai review

Kai Summary

Read through this one. 2 things worth your eyes before it merges, plus 2 decisions to say yes to. 👇

Where I'd land: 3/5 — small fixes first.

3 confirmed findings. Intent partial; readiness 3/5.

Decisions

Correct as written, but somebody should say yes to these:

  • The conservative readiness cap (any confirmed defect → ≤3, any open decision or unresolved allegation → ≤4) changes the merge signal every kai review-commit consumer reads; it tightens the badge deliberately, and whoever owns that badge should sign off. I could not read the consumer that renders this score, so its effect on the PR badge is asserted from the code, not confirmed downstream.
  • The missing-directory false-finding path (concern 1) publishes a "confirmed defect" and an actionable remedy to a real PR for behavior an independent adjudicator judged to conform to the requirement — that is wrong merge-blocking advice to the author until requirement-anchored assessment lands.

Findings

cmd/kai/review_commit_challenge.go:683-692 / cmd/kai/review_commit_missingdir_test.go:145 — the gate treats a failed "intended-behavior" assertion as an observed violation supporting the defect, so a challenger mislabelling the requirement's own behavior as a defect publishes a false confirmed finding with a wrong-directory remedy; the red test proving this is committed unfixed, leaving the suite failing (I could not confirm whether CI excludes it).

The gate derives 'violation observed' from 'the model declared intended behavior failed,' but whether a failed intended-behavior assertion is a defect or the requirement's own behavior is a requirement-anchored judgment the gate never makes. The committed test TestStoppingAfterFailedCdIsNotPublishedAsADefect fails on this code because the validator publishes the missing-directory case as a supported defect with a wrong-directory remedy, and no CI exclusion or skip was found in the provided sources.

Remedy: Either implement requirement-anchored assessment of behavior and remedies (as the commit subject names as future work), or add a build-tag/skip marker with tracking so the suite stays green until that lands. The test must not fail on master without an exclusion.

cmd/kai/review_commit_challenge.go:734-740 — decisions are validated for citations but never for requires_runtime, so a runtime-behavior decision can publish supported without an experiment, the exact failure the allegation path was rebuilt to prevent.

rcDecisionCheck has no requires_runtime field, and the decision validation loop never applies the observation-derived runtime-evidence downgrade. A decision alleging runtime behavior can publish 'supported' on a source citation alone, with no experiment — the exact gap the allegation path was rebuilt to prevent.

Remedy: Add a requires_runtime field to rcDecisionCheck (or classify decisions by their content) and run the same observation-derived downgrade switch as allegations. Alternatively, document that decisions are definitionally non-runtime and enforce that their evidence cannot cite experiments.

cmd/kai/review_commit.go:991-1006 — the deep path records Models.Draft without Provider and never captures the draft response's upstream provider, unlike the fast path, leaving an audit hole in deep-review provenance where the evidence doc claims completeness.

The deep path sets res.Models.Draft = rcPhaseModel{Configured: model, Requested: model} with no Provider, and never captures the draft response's upstream ProviderName, unlike the fast path which records it. A deep-review bundle will carry an empty draft.provider field where the fast path carries a real one — an audit hole exactly where the evidence doc claims completeness for both phases.

Remedy: Capture and set res.Models.Draft.Provider from the draft response's ProviderName in the deep path (rcRunReviewAgent), mirroring the fast path's res.Models.Draft = rcPhaseModel{Requested: model, Provider: resp.ProviderName}.

Limitations

  • Could not read the CI configuration (GitHub Actions, Makefile, or build scripts) that determines whether go test ./... runs the missing-directory test unguarded, skips it, or tolerates a red suite — the draft's own stated limitation. No CI config was in the provided sources.
  • Could not read the downstream consumers of the emitted bundle (kai-server, Atlas/CI badge renderer) that interpret the challenge JSON, the incomplete flag, and the merge-readiness score — they live in sibling repos not visible here.
  • Did not run the Go test suite itself (no Go toolchain available in the review_shell environment); verdicts on test behavior are from static reading of the code and fixtures.
  • Did not verify the runtime behavior of Docker or the sandbox image; sandbox-related claims are from the code, not from execution.

Decisions (need your call)

  • The conservative readiness cap (any confirmed defect → ≤3, any open decision or unresolved allegation → ≤4) changes the merge signal every kai review-commit consumer reads; it tightens the badge deliberately, and whoever owns that badge should sign off. I could not read the consumer that renders this score, so its effect on the PR badge is asserted from the code, not confirmed downstream.
  • The missing-directory false-finding path (concern 1) publishes a "confirmed defect" and an actionable remedy to a real PR for behavior an independent adjudicator judged to conform to the requirement — that is wrong merge-blocking advice to the author until requirement-anchored assessment lands.
