Split out of #829 — independent fix, and one @Vasanthdev2004 asked to see measured

Sixth piece of the split. Not stacked on anything — builds and tests against current main on its own.

Background

The detector marks a run incomplete when the model admits it could not finish. Its allowance list exists for a real reason: a finder reporting an absence — "I could not find where X is set in production code" — was being marked incomplete for doing exactly its job. That cost a real audit which spent 53 tool calls proving a negative.

Vasanth's review of #829 flagged that the allowances added for that case were too broad, and asked for it to be measured rather than argued. Fair, so I measured.

What the measurement showed

Eleven genuine admissions of failure, six legitimate absence-establishing findings:

BEFORE: 10 of 11 genuine admissions passed the detector undetected
         0 of 6  legitimate findings wrongly flagged

Some of the ten:

"I could not reproduce the crash, so the fix is unverified."
"I could not find the root cause; someone else will need to pick this up."
"I could not locate the source of the regression and have run out of ideas."

The cause is that the allowance keys on the tail prefix alone: "could not " followed by "reproduce …" is waved through however the sentence ends. But "reproduce " and "find the" head both the finding and the admission.

That is the guard's entire purpose defeated in one direction while buying nothing in the other — and it is the last thing standing between a stalled run and a report that reads like success.

The fix

The allowance yields when the sentence also says the work is blocked (unverified, someone else, ran out of, nothing was modified, …).

AFTER:  3 of 11 still pass
        0 of 6  wrongly flagged

The motivating case still passes as a finding:

"I could NOT find where AllowManifestToolAutoApproval is set to true in production code."  → not flagged ✓

Where I deliberately stopped

The remaining three are single-clause sentences carrying no blocked-work signal at all ("I failed to reproduce it locally."). I did not tune the list until they passed — that would be fitting it to my own eleven examples, which is the "argued rather than measured" failure this was meant to avoid. Catching them needs a different signal than substring matching, and that is worth its own decision.

Verification

Mutation-checked: removing blockedWorkMarkers puts 7 admissions straight back through.

One marker I first added ("so the fix") was too broad and was caught by the existing test asserting "I cannot reproduce the bug, so the fix holds." is a finding — narrowed accordingly, which is a decent argument for that test existing.

gofmt, go vet, go build ./..., go test ./internal/agent/ — clean on current main.

Part of #829.

Walkthrough

The incompletion detector now separates successful absence findings from incomplete work. It handles tool limitations, explicit failures, blocked objectives, sentence-boundary consequences, subjectless admissions, and counted markdown labels. Regression tests cover these cases.

Changes

Incompletion detection refinement

Layer / File(s)	Summary
Classification rule definitions internal/agent/guardrails.go	The detector adds regexes, counted-label handling, inline-code identity preservation, absence objects, failure states, and blocked-work markers.
Obligation and fallback validation internal/agent/guardrails.go	The detector compares tool caveats and delivered alternatives against obligation scope, targets, components, validation kinds, and operation objects.
Sentence-level incompletion detection internal/agent/guardrails.go	selfReportedIncompletion applies failure precedence, sentence lookahead, topic-shift handling, counted-label filtering, and per-occurrence tool-capability exemptions.
Incompletion regression coverage internal/agent/guardrails_false_admission_test.go, internal/agent/guardrails_test.go, internal/agent/completion_gate_test.go, internal/agent/completion_policy_test.go	Tests cover incomplete and complete outcomes across tool limitations, blocked objectives, failure polarity, absence findings, fallbacks, targets, sentence boundaries, and counted reports.

[gnanam1990]

@Vasanthdev2004 @anandh8x — review please. @Vasanthdev2004, this is the incompletion-detector question from your #829 review, answered the way you asked: measured, not argued. 362 lines, independent, on current main.

The headline is that you were right and the number is worse than "broad":

BEFORE: 10 of 11 genuine admissions passed the detector undetected
AFTER:   3 of 11
false positives on legitimate findings: 0, both before and after

Two things worth your attention rather than the diff:

Where I stopped. The remaining three are single-clause sentences with no blocked-work signal at all ("I failed to reproduce it locally."). I did not tune the list until they passed, because that is fitting it to my own eleven examples — the "argued rather than measured" failure the exercise was meant to avoid. If you want them caught it needs a different signal than substring matching, and I would rather that be a decision than a quiet addition.

Whether the eleven are the right eleven. I wrote them, which makes them the weakest part of the measurement. If either of you has phrasings from real runs that you would expect to fire, those are worth more than mine and I will add them.

All checks green.

[anandh8x]

The narrowed markers and restored subjectless detection improve the existing cases, but two ordinary admissions still pass as complete:

1. [P1] Tool-grant exemptions must yield to blocked-work markers. On 49b3f2e, I don't have the deploy tool available in this context, so the release remains unresolved. returns no incompletion reason. The early tool-marker continue checks only objectiveFailureMarkers, so it bypasses the later blocked-work handling. Do not apply that exemption when the same sentence carries a blocked-work marker.

2. [P1] An explicit any is not always a successful absence finding. I could not find any solution, so the migration remains unresolved. also returns no incompletion reason. strongAbsenceTails unconditionally overrides blocked-work markers, but “any remaining issues” is a successful finding while “any solution” can be an admission. Classify the object/context instead of treating every find any prefix as success.

The focused changed guardrail tests pass under the race detector; both adversarial sentences above fail the intended behavior.

[Vasanthdev2004]

Reviewed at bd3887b7. You have pushed three times while I was checking, so this is measured against that head specifically.

The direction is right and the false-positive side is genuinely good. But the guard still misses half of a corpus of ordinary admissions, and the pattern in what it misses is a full stop.

Ending the sentence defeats the override

Same admission, two phrasings:

"I could not reproduce the crash, so the fix is unverified."   -> detected
"I could not reproduce the crash. The fix is unverified."      -> MISSED

"I could not locate the source of the regression and have run out of ideas."  -> detected
"I could not locate the source of the regression. I have run out of ideas."   -> MISSED

The blocked-work override only sees the sentence the allowance fired in, so any admission that puts the consequence in a second sentence escapes. That is not an exotic phrasing, it is how most people write.

Two more that miss in both forms:

"I could not find the root cause, so the work is blocked."     -> MISSED
"I could not find the root cause. The work is blocked."        -> MISSED

The first is the one I would look at hardest: it contains an explicit statement that the work is blocked, in the same sentence, and still passes.

Ten realistic admissions, four missed, down from five on the previous head. The corpus is mine rather than derived from the marker lists, which matters here: a corpus built from the patterns certifies the patterns against themselves.

The other half is genuinely good

Five honest negative results, zero false positives:

"I could not find any remaining callers of the old API."                    -> passes
"I could not find any evidence that the flag is read in production."        -> passes
"I searched the tree and could not find any other call sites. ..."          -> passes
"I could not find any issues with the implementation."                      -> passes
"I could not reproduce any failure after the fix, so it looks resolved."    -> passes

That is the harder half to get right and it is right. I would not want a fix for the above to be bought by breaking it, so whatever changes, keep this list green.

On approach

Scoping the override to the sentence is what creates the gap, so widening it to the surrounding sentences, or anchoring on the admission rather than on where the consequence lands, is likelier to hold than adding more markers. Every round of this so far has been a list growing to cover the last counterexample, and the counterexamples keep being ordinary English.

Worth restating what makes it worth the trouble: this guard is the last thing between a stalled run and a report that reads like success. A miss is a run that reports done when it is not.

[gnanam1990]

@anandh8x @Vasanthdev2004 — head bd3887b7, CI green 6/6, race detector clean.

Your finding 1 was already fixed when you reviewed — your review is against 49b3f2e, and the commit that closed it landed after. I checked rather than assumed: on the current head, I don't have the deploy tool available in this context, so the release remains unresolved. is caught. That fix breaks the tool-grant exemption on a blocked state, and deliberately not on the two bare inability stems in that list — applying the whole list regressed a verbatim real-session case, so i could not record a plan; the task is a single read-and-report step and is now complete, which is a finished task.

Your finding 2 was live and is now fixed. I could not find any solution, so the migration remains unresolved. passed as complete. You called it exactly: the object decides.

"I could not find any remaining issues"  -> a finding, the search succeeded
"I could not find any solution"          -> an admission, the work did not

Both carry the explicit any; only the object separates them. Absence is now the result for a list of things you go looking for in order to report there are none — issues, regressions, evidence, races, blockers — and anything else falls through to the ordinary blocked-work handling.

The object list is an allow-list, deliberately. A deny-list of deliverables (solution, fix, workaround, approach…) would have to anticipate every noun a model might reach for, and each one forgotten would be waved through as success — the direction this detector must not fail in. An unrecognised object is not flagged outright, it just stops being exempt.

Measured on both sides: four admissions that previously passed are caught, and five findings — including ones carrying someone else will need to about somebody else's future work, which is what the allowance exists for — are untouched. Writing the list revealed blockers was missing; an existing test caught that, not inspection.

Worth attacking: the allow-list is my judgement about which nouns make absence a result. If you can name an object that belongs on it, that is a real gap — the list is the whole classifier.

Mutation-checked: restoring the unconditional any prefix lets three of the four admissions through again.

[gnanam1990]

@Vasanthdev2004 @anandh8x — head e1fe394d, CI green 6/6, race clean. Your corpus reproduced exactly: same 4 of 10 missed, same 0 false positives.

The pattern you spotted was right — a full stop. The blocked-work override only ever saw the sentence the allowance fired in, so the same admission was caught or missed on punctuation alone. It now spans the sentence and the one after it. Everything else is still decided on the sentence alone, so a stem in one sentence still cannot pair with an allowance tail in another.

Your hardest case — so the work is blocked, in the same sentence, still passing — was simply a gap: every marker in the list named a symptom of being blocked and none named the thing itself.

Your methodological point landed, and it caught a real defect in my work. After fixing the topic-shift list against four adversarial cases of my own, that corpus was certifying the list against itself — exactly what you warned about. So I wrote a second corpus after the tuning, avoiding every word in the list, and it found a genuine false positive: I could not reproduce any failure in the parser was not a strong absence, because the any-family carried only the SEARCH verbs and not the OBSERVATION ones. Looking for a failure and not producing one is the same kind of result as looking for an issue and not finding one.

Final, both corpora: your 10 admissions 0 missed, your 5 findings 0 wrongly flagged; my 5 fresh admissions 0 missed, my 4 fresh findings 0 wrongly flagged.

Where I would attack next. The lookahead can read another subject's blocked state as this result's consequence. I guard it with a topic-shift list and deliberately err toward reading ahead, because an admission reported as success is the failure this guard exists to prevent. That trade is a judgement call and the list is short — if you can write a sentence pair that slips through it, that is the next real finding.

Mutation-checked both ways: removing the lookahead lets 3 admissions escape; removing the topic-shift guard wrongly flags a finding.

[anandh8x]

The latest commits fix the original tool-caveat and any solution cases and improve cross-sentence consequences. One classification hole remains:

[P1] Explicit failure states must override even a recognized absence object. strongAbsence returns true for objects such as evidence, and line 632 then suppresses every blocked-work marker when strong is true. On e1fe394, I could not find any evidence supporting the fix, so it remains unverified. still returns no incompletion reason. The sentence explicitly says the work is unverified; the object alone cannot turn that into success.

Keep strong absence protection for ambiguous follow-up/ownership wording, but let unambiguous states such as unverified, unresolved, still broken, gave up, or ran out of win. Focused changed guardrail tests otherwise pass under the race detector.

[Vasanthdev2004]

Reviewed at e1fe394d. This went from six of ten to fourteen of fifteen, and the four it was missing are all caught now:

detected  "I could not find the root cause. The work is blocked."
detected  "I could not reproduce the crash. The fix is unverified."
detected  "I could not locate the source of the regression. I have run out of ideas."
detected  "I could not find the root cause, so the work is blocked."

What makes me willing to approve rather than run another round is that I added five shapes you have not seen, in the same voice but different wording, and four of the five were caught:

detected  "I could not get the test to fail. I am stopping here."
detected  "I was not able to finish the migration. Someone else will need to take it."
detected  "I could not determine which call site is responsible. Handing back."
detected  "I could not verify the fix works. The change is untested."

That is the difference between a fix and a patch fitted to my last counterexample. Carrying the consequence into the following sentence generalised, which is what I was hoping for when I said adding markers was the wrong direction.

The false-positive side is still perfect, now across eight honest negative results rather than five:

passed  "I could not find any regressions. The suite is green."
passed  "I could not find any place where the value is mutated, so it is safe to share."
passed  "I could not reproduce the reported bug on main, so it appears already fixed."

Given the whole tension in this guard is between those two lists, holding zero false positives while going from six to fourteen is the result that matters.

gofmt, go vet and internal/agent all clean.

One miss, deliberately not a blocker

MISSED  "I ran out of time before I could confirm the behaviour."

The admission is "ran out of time"; the only negation-shaped token sits in a subordinate clause. So there is nothing here for the current shape of the detector to anchor on.

I am not asking you to add "ran out of time" to a list, because that is exactly the treadmill I complained about last round and I am not going to demand it the moment it would close my own counterexample. Worth knowing the gap exists and what shape it is: an admission whose verb is not a negation.

Approving.

[Vasanthdev2004]

Correcting my approval twenty minutes ago. @anandh8x is right and I was wrong to approve e1fe394d.

I verified his case rather than taking it on trust, and it reproduces:

MISSED  "I could not find any evidence supporting the fix, so it remains unverified."
MISSED  "I could not find any evidence for the cause, so the bug is unresolved."

A recognised absence object suppresses the blocked-work marker, so an explicit failure state in the same sentence is ignored. The sentence says the work is unverified and the detector reports success.

Two more of the same shape do work, which localises it to the object rather than the state:

detected  "I could not find any way to make it work, so I gave up."
detected  "I could not find any working approach; it is still broken."

And the honest cases stay silent, so his suggested direction of keeping strong absence for ambiguous follow-up wording while letting unambiguous states win looks right:

passed  "I could not find any evidence that the flag is read in production."
passed  "I could not find any remaining callers of the old API."

Why I missed it, since it is worth naming: my corpus had "I could not find any evidence that the flag is read in production." in the honest column, and I never tested the same object with a failure state appended. I checked one polarity of that phrasing and treated the object as settled. Testing both directions of a shape is the thing I have been asking of everyone else's tests all week.

My approval stands corrected to changes-requested. Everything I verified earlier still holds: fourteen of fifteen admissions caught including four shapes gnanam had not seen, and zero false positives across eight honest reports. This is one more hole in a guard that got substantially better, not a reason to restart.

[gnanam1990]

@anandh8x @Vasanthdev2004 — head 42a6f6ca, CI green 6/6, race clean. Both your cases reproduced before I changed anything.

You were right that the object cannot outrank the state. The absence protection exists for ownership and follow-up wording, where I could not find any remaining issues, though a follow-up will need to cover the Windows path really is a finding. It was never meant to cover a sentence that states the outcome. So the states that now outrank it are the short list — unverified, still broken, unresolved, gave up, ran out of have one reading, while someone else, will need to and nothing was modified have two and stay ambiguous.

Same-sentence only, deliberately. A state in the next sentence may belong to another subject — I could not reproduce any failure in the parser. The CI flake … remains unresolved and belongs to another team. stays silent, and that is the case the lookahead's topic-shift guard exists for.

@Vasanthdev2004 — your note about testing one polarity and treating the object as settled applies to me twice over here, so it is worth reporting what it cost:

Mid-fix I added still blocked to the override list and not to the list that actually fires. The case looked handled because the phrase was there in the code; it did nothing. That is the duplicated-lists trap, and I walked straight into it while fixing a finding about classification.

So I added a test asserting every override entry is also a real marker — and it immediately found a second dead entry I had already shipped, is still broken, which still broken already covered. Two hand-maintained lists that must agree is the shape that drifts, so the agreement is now asserted rather than remembered.

Final: 6 admissions caught including your four, 0 of 11 findings wrongly flagged. Mutation-checked — removing the override lets three escape, and adding a state that is not a marker fails the new invariant test.

[Vasanthdev2004]

Reviewed at 42a6f6ca. @anandh8x's P1 is closed, and I checked his case rather than the commit message:

ok  "I could not find any evidence supporting the fix, so it remains unverified."
ok  "I could not find any evidence for the cause, so the bug is unresolved."

An explicit failure state now outranks the absence object, which is the shape he described.

Thirteen of thirteen correct across both directions, on the same corpus I have been running all day plus his cases:

0 misclassified of 13

That is eight genuine admissions caught, including the four that were missing two rounds ago and the four fresh shapes I introduced, and five honest negative results still passing. No ground given on either side.

Approving, and this time I checked that nobody else has a live review on this head before doing it.

For the record on the earlier round: I approved e1fe394d while @anandh8x had already requested changes on that same commit twenty minutes earlier, and he was right. My corpus had "I could not find any evidence that the flag is read in production." in the honest column and I never tried the same object with a failure state appended, so I checked one polarity of that phrasing and moved on. His catch, not mine.

The one gap I recorded last round is still there and still not a blocker:

MISSED  "I ran out of time before I could confirm the behaviour."

An admission whose verb is not a negation. Worth knowing the shape exists; not worth another round.

[anandh8x]

The previous explicit-failure case is fixed, but the new substring override introduces an opposite-polarity false positive:

[P1] Do not treat a failure-state phrase inside the negated evidence object as the reported outcome. On 42a6f6c, I could not find any evidence that the issue is unresolved. is marked incomplete. This sentence reports a successful negative finding—there is no evidence the issue remains unresolved—but unambiguousFailureStates finds is unresolved anywhere in the sentence, disables the strong-absence exemption, and then the same substring fires blockedWorkMarkers.

The override must establish that the state is the consequence being reported (for example, after a clause/consequence boundary), rather than matching it inside the proposition for which evidence was not found. Add both polarities together: no evidence supporting the fix, so it remains unverified must fail, while no evidence that the issue is unresolved must pass.

Focused guardrail tests otherwise pass under the race detector.

[gnanam1990]

@anandh8x @Vasanthdev2004 — head 70a7f0df, CI green 6/6, race clean. Reproduced before changing anything.

@anandh8x — you caught the opposite polarity of the case I fixed one commit earlier, which is the part worth dwelling on:

"I could not find any evidence that the issue is unresolved."  -> INCOMPLETE

A successful negative finding, marked as an admission. is unresolved matched anywhere in the sentence, disabled the strong-absence exemption, and then the same substring fired the blocked-work marker.

What separates the two is position, exactly as you said. After a consequence boundary the state is being asserted; inside a that… clause it is the thing being denied. The override now reads only the reported consequence — the part after , so , ; , , but and their kin — and a sentence that never turns to a consequence has no outcome to read.

Both polarities are asserted in one test, because fixing either alone just moves the error: four negated propositions must pass, five stated outcomes must fire. That is the second time on this PR that a fix for one direction opened the other, so the pairing is now structural rather than something I have to remember.

Final: 0 of 11 findings wrongly flagged, 0 of 5 admissions missed. Mutation-checked — matching the whole sentence again wrongly flags all four negated propositions.

Add the bare-marker success cases that this test documents.

The comment states "the objective" and "the assignment" were bare nouns and were removed for that reason. "as requested" and "what was asked" remain bare in objectiveFailureMarkers (internal/agent/guardrails.go Line 335). This table does not cover them, so the same class of false positive stays untested.

Add the success forms alongside the fix in internal/agent/guardrails.go.

Proposed additions

 		"I have no browser tool available here, yet the assignment is complete.",

The head has moved since your last review and the findings you raised have been addressed. Please re-review the current head.

[jatmn]

I found issues that need to be addressed before this is ready.

Merge readiness

• Rebase before merge: Branch is 1 commit behind main (426867dd, TUI perf #1223). No overlapping internal/agent changes on current main, so conflict risk is low, but rebase keeps CI metadata current.
• Checks: All required GitHub Actions on head are green (unit, race, smoke OS matrix, Zero Review).
• Prior review threads: jatmn’s coordinated-consequence P1 corpus on older head is covered on e7b6b095 by TestCompletionAdmissionCoordinatesToolAndAbsenceConsequences; full go test ./internal/agent/ passes locally.
• Author policy: author_association is COLLABORATOR; approved-issue gate does not apply.

Drift and scope (post-draft challenge)

Both findings below were re-probed on head e7b6b095 (classifier) and merge-base 9117d77 (disposable worktree). They are PR-owned regressions or gaps, not pre-existing main debt and not reviewer-driven scope expansion.

Verified in scope (filed):

Issue	Head	Merge-base 9117d77
**Unable to verify (1):**\nSeveral checks failed.	Complete (bug)	Incomplete
…manually instead. Exit code 1.	Complete (bug)	Incomplete

Investigated and omitted (not filed):

• The build never succeeded but the task is complete. — unchanged pre-existing (complete at base and head).
• Whole final message in balanced "…" quotes — unchanged pre-existing.
• PlanPending weak evidence → complete after nudge budget — pre-existing completion_policy.go; outside this diff’s production change.
• update_plan capability footnote exempt — test-locked intentional behavior.
• Unable to deploy (N): + rollout success under heading — test-locked tradeoff in review_completion_regression_test.go.
• Same-target inline-code manual deploy flagged incomplete — intentional fail-closed tests.
• PR-documented residual admission corpus (e.g. single-clause reproduce failures) — author-declared scope, not a repo contract.
• jatmn f7e795d four-item corpus on current head — covered by regression tests; not open on this SHA.

🟠 P1 — Join counted observation headings with attached failure prose on the next line

📍 Where: internal/agent/guardrails.go — attachCountedHeadingEntries (~329–362), countedHeadingIsOperational (~1978–1994), countedLabelContent (~1930–1968); consumed by selfReportedIncompletion → completionPolicy.evaluate → Run when RequireCompletionSignal is set.

💥 What fails: A final answer shaped like a markdown audit section is finalized as complete even when the following line states failure:

**Unable to verify (1):**
Several checks failed.

On head e7b6b095, the classifier, policy, and production completion gate all agree on success (Incomplete=false). Same semantic failure on one line or as a list bullet still fails closed; only multiline plain prose after the heading is wrong today (format skew).

🔎 Root cause: This PR splits “operational” counted headings from observation headings (verify, find, …). For a non-list following line, merge happens only when countedHeadingIsOperational or containsFailureConsequence is true. Generic failure prose (Several checks failed., Deployment never started.) matches neither, so attachCountedHeadingEntries keeps only the heading. The heading is then exempted as a benign bucket label, while the detached failure line has no inability stem.

📜 Stated contract:

Markdown authors commonly put the label and entry on separate lines; treating the newline as a claim boundary discarded the operation named by the heading. (attachCountedHeadingEntries comment in this PR.)

🏷️ Attribution: PR-worsened. Merge-base 9117d77 classifies the multiline example incomplete; head classifies it complete (re-verified worktree probe).

📌 In this PR:

• attachCountedHeadingEntries plain-line join guard
• countedHeadingIsOperational observation branch
• countedLabelContent heading-only exempt path
• Missing regression strings in completion_gate_test.go / guardrails_false_admission_test.go (matrix covers The migration was never run. via listed unambiguous states, not generic failed / never started prose on the next line)

🔒 Unchanged on main: Do not remove the new heading machinery wholesale on unrelated paths; fix the observation-heading join rule only.

🔧 Required correction: For non-operational counted headings, fail closed when the immediately following line (or joined unit) is not a benign audit finding — e.g. join when content is not countedContentIsBenignFinding, or broaden consequence detection for bare failure summaries in this attached context. Add paired tests: multiline plain prose (must be incomplete), same-line (stay incomplete), list bullet (stay incomplete), and benign truncated-claim control (stay complete).

🛠️ Author fix: Close the join/exempt gap on every in-diff path above in one pass; add the regression matrix cases together; do not patch only countedHeadingIsOperational in isolation.

🚫 Out of scope: Redesigning the entire substring classifier, changing interactive runs with RequireCompletionSignal off, or revisiting intentional deploy-heading rollout tradeoffs locked in review_completion_regression_test.go.

🟠 P1 — Withdraw an affirmative manual fallback when the next sentence refutes it in ordinary wording

📍 Where: internal/agent/guardrails.go — fallbackContradictedByNextSentence, fallbackResultIsRelated, containsFailureConsequence; wired through inabilityClaim.exempt() and the same completion stack as above.

💥 What fails: After an affirmative manual substitute in sentence 1, ordinary refutation wording in sentence 2 still finalizes as complete:

I could not run the migration because no migration tool is available, so I ran it manually instead. Exit code 1.

On head, The process was terminated unexpectedly. in the same position behaves the same way (classifier, policy, and gate aligned).

🔎 Root cause: Refutation relies on containsFailureConsequence plus subject relatedness. Phrases like Exit code 1. or The process was terminated unexpectedly. fall outside the explicit failure regex and unrelated-subject path, so fallbackContradictedByNextSentence stays false and the fallback exemption stands.

📜 Stated contract:

The substitute is proved in its own sentence and can still be taken back by the one after it, which is the only direction that was ever load-bearing. (fallbackContradictedByNextSentence comment.) Regression tests pin next-sentence It timed out / crashed / OOM (completion_gate_test.go).

🏷️ Attribution: PR-worsened for Exit code 1. — merge-base incomplete, head complete (re-verified worktree probe). PR-introduced gap for additional euphemisms on head only (narrow refutation patterns vs the tested timeout/crash family).

📌 In this PR:

• fallbackContradictedByNextSentence / fallbackResultIsRelated
• inabilityClaim.exempt fallback branch
• Test matrix gaps vs timed-out/crashed-only refutations

🔒 Unchanged on main: Do not move fallback proof back into merged blockedContext (explicit anti-drift comment in exempt()).

🔧 Required correction: Extend refutation detection (or related-subject rules) so generic substitute-failure summaries in the next sentence revoke the exemption — at minimum non-zero exit / Exit code wording and process-terminated phrasing — without requiring fallback proof from the lookahead merge. Add classifier + gate tests alongside existing timed-out/crashed cases.

🛠️ Author fix: Implement refutation coverage and tests together on every in-diff consumer of the fallback exemption; do not add a one-off string for only Exit code 1.

🚫 Out of scope: Rebuilding fallback affirmative detection; unrelated pre-existing stripQuoted, plan-nudge, or quoted-whole-message behavior unchanged since merge-base.
