fix(agent): stop the incompletion allowances from swallowing genuine admissions

[gnanam1990]

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.

countedLabelSentence anchors the inability phrase to the sentence start, but it searches the whole sentence for the count. A real admission that carries any parenthesised number is then exempted:

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.

[Vasanthdev2004]

Re-reviewed at 1e2d3f74. All eleven from my last round are closed, and this time they are closed the way I hoped: each of the six helpers was inverted rather than extended.

• a paragraph under an operational heading attaches unless it affirmatively reports success, instead of only when it matches a failure word;
• the bookkeeping exemption holds only when the action is followed directly by its capability explanation, so a comma, nor, as well as, plus or along with in front of a second duty all fail closed;
• an execution verb covers only the components it governs, and any other word ends its reach, so skipped, left for later and deferred are all uncovered without being listed;
• the obligation keeps the head noun of its object, so release notes, release docs and a release candidate checklist are not the release;
• a code span that is not identifier shaped becomes an opaque token that declines the equivalence.

Reverting each of the five fails its named subtests. My forty seven strings went from twelve false completes to one, and that one is the remains unfixed case that main also swallows and I said I was not asking for. Package green, vet and gofmt clean, CI 9 of 9.

I then ran a second ring of twenty three, different words on the same six mechanisms, head against main:

	main	this head
swallowed (false complete)	0	2
over-fired (false incomplete)	9	4

Two false completes are left, and both are the same relationship jatmn's first finding named: an affirmative fragment clearing an explicit admission it does not belong to.

1. **Unable to deploy (1):** followed by Rollback completed successfully. is complete. affirmativeOutcomeParagraphPattern accepts any subject of up to four words, so a success about something else releases the heading, and a deployment that failed and was rolled back reads as done. An operational heading with a nonzero count is the admission on its own. I would drop the affirmative release for that case entirely: your control, the same heading followed by Production rollout completed successfully., is a report that contradicts itself, and a contradiction costing a turn is the right side to fail on.
2. I could not find where the flag is set; the source is the parser and the fix is outstanding. is complete. The adversative boundaries (but, though, yet) are handled structurally now, but affirmativeObservationConsequencePattern matches a fragment, so anything joined on with and rides through behind the source is. Requiring the matched fragment to be the whole consequence, nothing after it but punctuation, closes it without a word list.

The four false incompletes I am not asking about, for the record, since each only costs a turn: ran both the unit and the integration tests, ran the unit tests and then the integration tests, a repeated multiword code span (deliberate, per your comment), and a neutral next sentence after a substitute (Logs are attached below., It finished without errors.).

Same caveat as last time: both rings are drawn from where this branch's exemptions live, so they are biased against it, and main scores zero swallows on the second ring only because it exempts nothing there and pays nine false incompletes for it.

[jatmn]

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

Merge readiness

• All required GitHub checks are green on head 1e2d3f7487385b4629236b5aed0d6507eb7f252f, merge-base matches live main (99721c762), and there are no unresolved review threads. Author is a COLLABORATOR (approved-issue gate not applicable).
• Prior jatmn / anandh8x / Vasanthdev2004 threads on older heads appear addressed in the current matrices; re-verify the three findings below on this head rather than re-opening closed comment text verbatim.

Findings

• [P2] Apply the same capability-footnote contract to shell/browser grant wording as to update_plan
  Attribution: PR-introduced (capabilitySubjectOnly / capabilityOnlyToolFootnote on this branch).
  Stated contract: TestTheGrantExemptionStillCoversWhatItWasBuiltFor — a run naming its tool grant (read-only specialist context) must not be marked incomplete; TestAnHonestCaveatInsideDeliveredWorkIsNotAnAdmission (a statement about the tool grant).
  Root cause: capabilitySubjectOnly allow-lists update_plan / formatter / test vocabulary but not parallel specialist footnotes (browser, shell), so possession-denial stems fire even when the sentence only discloses the grant alongside read-only tools.
  What fails: I don't have a shell tool available in this specialist context; only read-only tools were provided. (and the browser-shaped variant) finalize as incomplete while the structurally parallel update_plan footnote is complete.
  In this PR (must close together):

  • capabilitySubjectOnly noun allow-list
  • capabilityOnlyToolFootnote / inabilityClaim.exempt capability branch
  • completion_policy_test.go / completion_gate_test.go paired complete controls for shell/browser footnotes (mirror existing update_plan rows)
    Unchanged on main: merge-base had no this footnote path.
    Required correction: treat read-only specialist grant disclosures consistently—either generalize the allow-list / polarity check beyond update_plan, or share one predicate for “grant-only footnote with read-only tools provided” so shell/browser match the passing controls. Add paired regressions through selfReportedIncompletion and completionPolicy.evaluate.
    Author fix: close the root cause on every in-diff row above in one pass; do not patch only update_plan strings in tests.

  Stated contract: TestCompletionPolicyToolExemptionPolarityAndObligations — I could not run the formatter because no formatter tool is available, so I checked it by hand. must decide CompletionComplete; file comments state false positives (marking finished work incomplete) are the worse failure mode.
  Root cause: when sentence i+1 is appended to blockedContext without a topic-shift marker, deliveredAlternativeAfter evaluates fallback success on the merged tail; a neutral follow-on (Documentation is outdated.) makes fallbackOutcomeIsAffirmative fail, so the earlier i could not stem is treated as a hard admission.
  What fails: formatter manual-check answers that are complete on their own become incomplete if the model adds an ordinary second sentence that is not blocked work and does not use an exact topicShiftMarkers phrase.
  In this PR (must close together):

  • selfReportedIncompletion blocked-context construction
  • deliveredAlternativeAfter / inabilityClaim.exempt tool-fallback branch
  • regression pair: manual fallback alone (complete) vs same + neutral follow-on (should stay complete) vs blocked follow-on (tests remain unverified, incomplete)
    Unchanged on main: merge-base lacked this cross-sentence blocked context.
    Required correction: scope fallback proof to the inability sentence (or the clause that contains the substitute), and use blockedContext only for blocked-state / consequence detection—not to re-score affirmative manual fallbacks. Keep existing Separately, / topic-shift controls that detach genuinely unrelated tails.
    Author fix: implement scoped fallback evaluation and add the paired tests above in one commit.
    Out of scope: removing next-sentence consequence detection for genuine admissions (keep The fix remains unverified. cases).

  Stated contract: TestCompletionGateRejectsCurrentHeadReviewAdmissions — I do not have the network access I needed, but the task is complete. must remain incomplete; TestCompletionGateStructuralReviewerMatrix (completion declaration cannot self certify) — I could not run the migration … but the task is complete. must remain incomplete.
  Root cause: the direct tool-limitation path only treats explicit blocked-state vocabulary as consequential; No write tool is available … so the fix is complete. has no inability stem and no blocked marker, so both selfReportedIncompletion and completionPolicy.evaluate return complete.
  What fails: models can assert the fix/task is complete solely because a write tool was unavailable, without substitute-work evidence—opposite polarity to the self-certification cases the gate already rejects when an inability stem is present.
  In this PR (must close together):

  • hasReportedFailureConsequence / blocked-state detection for tool-grant-only sentences
  • selfReportedIncompletion early tool-limitation branch
  • completion_gate_test.go / completion_policy_test.go paired rows: tool grant + fix/task is complete (incomplete) vs legitimate read-only completion footnotes (still complete)
    Unchanged on main: merge-base lacked this fast path.
    Required correction: reuse the same “self-certified completion without proof” rule already applied to migration/task is complete pairs—treat bare … the fix is complete / … the task is complete after an unavailable-tool statement as incomplete unless bounded substitute evidence exists (manual execution, harmless bookkeeping pattern, or explicit affirmative outcome). Do not regress update_plan bookkeeping-complete cases covered in the matrix.
    Author fix: close every in-diff row together with symmetric tests.
    Out of scope: semantic-check loop changes.

[gnanam1990]

All three findings are closed on 350d663f. Each was reproduced through selfReportedIncompletion before changing anything, and each fix was confirmed to fail with itself reverted.

[P1] A tool grant can no longer self-certify completion

No write tool is available, so the fix is complete. returned complete: no inability stem, no blocked marker, so nothing looked at it. The gate's existing self-certification rule — the one that refuses I could not run the migration … but the task is complete. — only ran inside the stem loop.

The discrimination is the connective, which is doing real work rather than matching keywords. A causal connective offers the absent tool as the cause of completion, which is the non sequitur. A concessive one asserts the opposite relationship — the tool was missing and the work finished anyway, so it was not needed — and those are legitimate. That split is what separates the new incomplete rows from three sentences already in the suite that must stay complete:

sentence	why
No write tool is available, so the fix is complete.	causal + bare declaration → incomplete
I have no browser tool available here, yet the assignment is complete.	concessive → complete
No write tool is available to me, so the objective was achieved by reading alone.	causal but names the substitute → complete
The assignment is complete; no shell was needed.	no tool-grant context → complete

Only a remainder that is the bare declaration and nothing else is treated as self-certification, so a sentence that accounts for the work is never caught. I could not call update_plan because that tool is unavailable, but the task is complete. is unaffected — concessive, and it keeps its existing stem exemption.

[P2] The capability footnote covers the whole grant

capabilitySubjectOnly allow-listed update_plan, formatter and test vocabulary but not shell or browser, so the structurally identical read-only specialist footnote finalized as incomplete for those two while the update_plan row passed. Same stem, same qualifier, same meaning; the list had simply never been given those nouns. They name tools in the grant rather than a missing resource, which is the distinction the allow-list exists to draw — I don't have the network access I needed is a resource and still never reaches this path, because it carries no tool marker.

[P2] A neutral next sentence no longer withdraws a manual fallback

blockedContext appends the following sentence so a consequence stated next door stays visible. That is right for detecting blocked state and wrong for re-scoring an affirmative substitute: evaluated on the merged pair, …so I checked it by hand. stopped being exempt the moment any ordinary sentence followed it, because Documentation is outdated. simply failed to re-affirm the fallback. Finished work became an admission, which this file calls the expensive direction.

Proof now comes from the inability sentence. The lookahead keeps the power to refute — that asymmetry is the whole correction, and it is load-bearing: It timed out., It was cancelled., It crashed. and The run was killed by the OOM killer. must all still land, and do.

That last one is caught structurally rather than by adding killed to a deny-list, for the reason fallbackHasUnprovenAdversativeOutcome already gives: a new failure synonym must not become completion evidence by being absent from a list. What it carries is a back-reference subject — it is a report on the substitute — and a report on the substitute that does not affirm it takes it back. Documentation is outdated. has no such subject and is left alone, which is precisely the neutral follow-on being protected.

Blocked-state detection still reads blockedContext, so …so I checked it by hand. Tests remain unverified. remains incomplete.

Coverage

Paired rows for all three run through both selfReportedIncompletion (completion_gate_test.go) and completionPolicy.evaluate (completion_policy_test.go), so the two consumers cannot drift: causal/concessive/method-naming tool grants, shell and browser footnotes mirroring the update_plan row, and the fallback triple — alone, with a neutral follow-on, with a blocked follow-on — plus a refuted-fallback row.

Reverting each fix fails its rows: the self-certification rule removed; concessives added to the causal list; shell/browser dropped from the allow-list; fallback proof put back on the merged tail; and the lookahead's power to refute removed.

Validation

fmt-check, go vet ./..., git diff --check, full go test ./..., zero-release build and smoke all clean on 350d663f, merge-base 99721c76.

Two environment notes, both verified against unmodified main so neither is this branch: /Users/kratos/dev here is a symlink to the real checkout, and running the suite through it fails internal/sandbox credential tests that pass from the real path — everything above was run from the real path. And make lint-static reports 4 staticcheck issues in files outside the module (~/Documents/Codex/...), from a stale golangci-lint cache; unused is clean, which is what mattered for the dead-code question here.

[Vasanthdev2004]

Re-reviewed at 350d663f. jatmn's three are closed, and each one holds when I take it back out: removing the shell and browser nouns fails both footnote rows, reading the fallback proof from the merged pair again fails the neutral follow-on row, and skipping the self-certification check fails all three causal rows. The back-reference rule earns its place too, since without it killed by the OOM killer goes back to passing. Package green, vet clean, CI 9 of 9.

Two things keep this at changes requested.

1. My two from last round are untouched. Both still finalize complete here and incomplete on main:

• **Unable to deploy (1):** followed by Rollback completed successfully.
• I could not find where the flag is set; the source is the parser and the fix is outstanding.

The asks stand as written: no affirmative release under an operational heading with a nonzero count, and the affirmative-observation pattern has to be the whole consequence, not a fragment of it.

2. This round's follow-on rule lets through a substitute that fell short. The fallback is now proved in its own sentence, and the next sentence can only take it back if it hits the failure vocabulary or opens with it, that, this, they or the <word>. Any other subject is read as a change of topic. After I could not run the formatter because no formatter tool is available, so I checked it by hand.:

second sentence                              main         1e2d3f74     this head
Several files are still unformatted.         incomplete   incomplete   complete
Two files still need formatting.             incomplete   incomplete   complete
Formatting is only partly done.              incomplete   incomplete   complete
I only got through half of the files.        incomplete   incomplete   complete
Unfortunately the check was interrupted.     incomplete   incomplete   complete

Those five are new this round. The same anchor is why jatmn's second finding is closed for his spelling only: Documentation is outdated. now completes, The documentation is outdated. does not, and neither do It is documented in the README., This matches the style guide. or The README explains the style rules. The opening word is standing in for the question that matters, which is whether the sentence is about the substitute's work. The gate already works out what that work was when it checks the substitute, the blocked activity and its object, so the follow-on can be asked the same thing: if it names that activity or its object, or it is the same first person carrying on, it has to affirm. If it shares nothing, it is neutral whatever word it opens with. That is one rule for both columns, and no list.

Not blocking. selfCertifiedCompletionAfterToolGrant is an exact match on twenty three declarations behind eleven connectives. Thirteen neighbours all finalize complete: so the fix is finished, so the bug is fixed, so the fix is complete now, so the patch is complete, so everything is done, so I consider the task complete, consequently the task is complete, meaning the task is complete, which means that the task is complete, the split ... available. So the fix is complete., the fronted Since no write tool is available, ..., the reversed The fix is complete because ..., and the declaration with a tail. Main swallows all thirteen as well, plus jatmn's original, so none of it is a regression and this head is one better. It is the list shape again, though. The sentence you protect, so the objective was achieved by reading alone, passes because it says how, and testing for that, a remainder that carries no account of the work, closes the class instead of one spelling of it.

Totals on the forty three strings I ran, false completes then false incompletes: main 14 and 13, 1e2d3f74 16 and 10, this head 20 and 5. Thirteen of the false completes on every tree are that self-certification ring, and main and the last head also have the original string jatmn reported. Beyond those, main has none, the last head had my two, and this head has seven.

Same caveat as before: the strings are drawn from where this branch's exemptions live, so they are biased against it, and main's clean column on the follow-ons is only because it exempts nothing there and pays for it on the right.

[jatmn]

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

Merge readiness

• Head 350d663f is mergeable against current main 99721c762 with no stale-base or release-metadata drift. All ten GitHub checks pass and the review threads are resolved. GitHub's review decision is CHANGES_REQUESTED, so approval remains blocked.
• This is an independent split from the still-open, broader #829. Its current diff is limited to the completion classifier and four test files; I did not find a newer PR that supersedes this scoped work.

Findings

• [P1] Keep a failed counted operation when a different operation succeeds
  internal/agent/guardrails.go:328-345
  Attribution: PR-introduced. **Unable to deploy (1):** followed by Rollback completed successfully. is complete at this head and incomplete at the merge base/current main.
  Stated contract: the changed countedHeadingIsOperational comment says the heading is retained for write/migrate/deploy/publish entries; the changed gate tests reject a counted deployment whose rollout failed and allow one whose rollout itself succeeded.
  Root cause: attachCountedHeadingEntries discards the operational heading whenever the next prose line matches a generic affirmative outcome, without checking whether that outcome clears the counted operation. countedLabelContent then drops the standalone heading. The first prose line is just how this appears; the rule belongs to the counted heading and its attached entries.
  What fails: a headless deployment run can report one failed deployment plus a successful rollback and finalize as successful. Moving the same text into a Markdown bullet makes it incomplete.
  In this PR (close together): the prose join and affirmative-outcome path in attachCountedHeadingEntries; the inline/bullet path in countedLabelContent; the operational-heading and same-operation-success rows in completion_gate_test.go. Check multi-entry headings so a successful entry cannot erase a separate failed one.
  Required correction: retain the nonzero operational failure unless the attached result actually resolves that operation. Keep the existing completed-rollout control complete, and add a failed-deploy/successful-rollback regression across the affected entry formats.
  Author fix: close this heading-identity rule in every in-diff row above in one pass; do not patch only line 335 or one Markdown shape. Keep the change within this PR's classifier and tests.
  Out of scope: changing Markdown rendering or the unchanged completion-policy framework.

• [P1] Classify the whole observation outcome, including what the search negated
  internal/agent/guardrails.go:1783-1810,2037-2065
  Attribution: PR-introduced false completion and PR-worsened false incompletion. I could not find where the flag is set; the source is the parser and the fix is outstanding. is complete here but incomplete on the merge base/current main. Conversely, I could not find any evidence of an unverified fix is incomplete here but complete on both baseline trees.
  Stated contract: the existing acceptance-gate test says an admission that the objective was not met must be incomplete. The changed guardrails comment says, “THE STATE HAS TO BE THE OUTCOME, NOT PART OF WHAT WAS NEGATED,” and the changed gate test says an affirmative observation cannot erase unfinished work.
  Root cause: the bounded-observation path treats the source is as affirmative even when the rest of the same asserted consequence says the fix is outstanding. The strong-absence path makes the inverse scope error: it treats unverified inside the searched-for of an unverified fix object as an asserted failure, while recognizing only a literal that proposition as negated.
  What fails: headless runs can accept a final answer that says the fix remains outstanding, while a completed negative-evidence audit can be marked failed and retried.
  In this PR (close together): observationConsequenceIsAffirmative / boundedObservationHasUnresolvedConsequence; strongAbsenceHasBlockedOutcome / reportedConsequence; the paired bounded-observation and negative-proposition tests in completion_gate_test.go and guardrails_false_admission_test.go. The changed policy test should cover the same decisions.
  Required correction: judge the full asserted observation result and keep failure-state words inside the negated search proposition from becoming outcomes. Add paired and the fix is outstanding and evidence of an unverified/unapplied ... cases while preserving the existing affirmative-source and that controls.
  Author fix: close both polarity errors at all listed in-diff paths in one pass; do not add only outstanding to a deny-list or only of to one example. Keep the change within this PR's classifier and tests.
  Out of scope: rewriting the completion policy or changing unrelated negative-search behavior on main.

• [P1] Require proof that a manual substitute actually completed the work
  internal/agent/guardrails.go:871-904,1991-2030
  Attribution: PR-introduced. After I could not run the formatter ... so I checked it by hand, follow-ons such as Several files are still unformatted, Formatting is only partly done, and I only got through half of the files are complete here but incomplete at the merge base/current main. A same-sentence migration fallback with only 30 of 100 rows moved is also complete here and incomplete at baseline.
  Stated contract: the changed fallbackOutcomeIsAffirmative comment says a past-tense action is not completion evidence when the bounded fallback says it was partial or failed afterwards. The changed policy and gate tests require partial, failed and next-sentence blocked substitutes to remain incomplete.
  Root cause: same-sentence fallback proof accepts a positive action while missing quantitative partial results (only 30 of 100, 70 rows remain pending). The next-sentence check uses failure-word lists and sentence-opening words as a proxy for whether the follow-on reports on the substitute. Neither path proves that the formatter or migration work finished.
  What fails: the headless completion gate can finalize unfinished substitute work as success. The current next-sentence rule also depends on wording rather than whether the follow-on names the substitute's action or object.
  In this PR (close together): deliveredAlternativeAfter / fallbackOutcomeIsAffirmative for same-sentence result polarity; fallbackContradictedByNextSentence for related follow-ons; the changed fallback rows in completion_gate_test.go and completion_policy_test.go. Cover formatter and migration examples, same-sentence quantitative partial results, and related next-sentence results.
  Required correction: require an affirmative completed result for the failed obligation across the substitute clause and any related follow-on. Keep neutral unrelated follow-ons neutral and successful substitutes complete; add paired tests for those controls.
  Author fix: close the result-proof rule on every in-diff path above in one pass; do not patch only the first follow-on phrase or add a few failure synonyms. Keep the existing policy/gate and unrelated main paths unchanged.
  Out of scope: a general redesign of the natural-language classifier.

[euxaristia]

An honest partial fix: the allowance now yields when the sentence also states blocked-ness, measured (undetected admissions 10/11 down to 3/11 with zero false positives on the corpus) and regression-tested, but it is still an English-string heuristic that rephrasing defeats, and the PR is candid that it stopped there. Merge-worthy as an improvement as long as the claim stays reduced, not fixed.
