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.

@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.

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.

Gitlawb#911 and Gitlawb#912 both moved when CodeRabbit's findings were fixed, so this branch
was behind again in two more packages:

  internal/sandbox  the concurrency test was not concurrent — instrumented over
                    200 runs, 194 peaked at ONE simultaneous holder — and its
                    helper skipped outright on Windows
  internal/agent    "the objective" and "the assignment" were bare nouns, so a
                    finished answer reporting success was read as admitting
                    failure; and a tool caveat excused blocked work

Same check as before: all 17 files the five split branches touch are
byte-identical to their split heads. Full suite, fmt-check, vet, release build
and smoke pass.

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.

@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.

@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.

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.

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.

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.

@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.

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.

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.

@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.

335-335: 🎯 Functional Correctness | 🟠 Major | ⚡ Quick win

Bare objective markers break the tool-grant exemption on successful answers. "as requested" and "what was asked" are not verb-anchored, so a sentence that names a tool grant and then reports success loses the exemption and fires on the inability stem.

  • internal/agent/guardrails.go#L335-L335: replace both bare entries with verb-anchored failure forms.
  • internal/agent/guardrails_false_admission_test.go#L217-L237: add success-form cases using as requested and what was asked to the non-admission table.

613-621: 🎯 Functional Correctness | 🔵 Trivial | ⚡ Quick win

countedLabelSuffix matches a count anywhere in the sentence.

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:

Unable to complete the task (2 attempts); the build never succeeded.

Anchor the count to the label prefix instead, so only heading shapes match.

Proposed fix
-var countedLabelSuffix = regexp.MustCompile(`\(\s*\d+\s*\)`)
+// The count must close the LABEL, optionally followed by markdown emphasis and
+// the separating colon: "**Unable to verify (1):**".
+var countedLabelSuffix = regexp.MustCompile(`^[-*#>\s]*unable to [^;(]*\(\s*\d+\s*\)\s*[:*]`)

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.

 		"I have no browser tool available here, yet the assignment is complete.",
+		"I don't have a browser tool available in this specialist context; the report is formatted as requested.",
+		"No shell tool is available in this context, and the summary covers what was asked.",
 	} {

Re-checked at 367831fa, against the merge base (main at 6937a309), same harness as before.

The first ring is closed, and closed the right way. All thirteen of my strings hold, and all ten of the neighbours that regressed against base last time now match base. The three that still swallow are the three base swallows, so on those thirty-two strings this branch is now exactly base. More to the point, the commit does the three inversions I asked for rather than lengthening the lists: subjectElidedFailure classifies from the predicate instead of naming the adverbial, markdownListEntryPattern takes any CommonMark marker and tolerates a blank line, and boundedObservationHasUnresolvedConsequence is written incomplete-by-default with an affirmative allow-list as the release. That is the shape. Thank you for doing it that way.

So I went one ring further out, with eighteen strings that have never appeared in any review of this PR: connectors outside the boundary list, verbs outside the missed-work list, heading labels other than "Unable to", and affirmative controls that have to stay complete so the inversion is not just "everything after an inability fails". Head against base:

base this branch
wrong 5 of 18 12 of 18

Seven are new here. Five of the seven swallow work base catches:

I could not find where the flag is set, which leaves it broken.
I could not find where the flag is set, meaning nothing was changed.
I could not find where the flag is set and it stays wrong.
I could not find where the flag is set. It is still wrong.
I don't have a write tool available in this context and so never touched the file.
I don't have a write tool available in this context and accordingly did not land it.

(That is six; the seventh is the other direction, below.)

Why: the inversion is behind a word list

The incomplete-by-default rule only engages once hasExplicitConsequenceBoundary says a consequence is present, and that is decided by this:

func explicitConsequenceBoundary(boundary string) bool {
	return strings.HasPrefix(boundary, ";") ||
		strings.Contains(boundary, " so ") || strings.Contains(boundary, " but ") ||
		strings.Contains(boundary, "therefore") || strings.Contains(boundary, "leaving") ||
		strings.Contains(boundary, "because") || strings.Contains(boundary, "since")
}

"which", "meaning", a bare "and", and a sentence break are not in it, so for those the code falls through to containsFailureConsequence, which is the deny-list again. The allow-list default is real, but it sits behind a connector list, so the same defect moved one level up. The comment on boundedObservationHasUnresolvedConsequence says "a consequence stays incomplete by default; only an affirmative result or an explicit topic shift releases it", and that is the right rule; it is just not what happens outside the list.

The two elided ones are subjectElidedMissedWorkPattern, a verb list: "touched" and "land" are not in it. The negation is the signal there, not the verb.

The seventh, going the other way

I could not find any leftover references; the cleanup is complete.     base COMPLETE   here INCOMPLETE

affirmativeObservationConsequencePattern keys the release on a noun list, and "cleanup" is not on it. This is the safe direction, and I would rather have this than the reverse, but it is the exact class this PR exists to reduce and base gets it right, so it is worth saying out loud. I am not blocking on it alone.

Not on this PR

Five of the eighteen are wrong on base as well, and identically here: **Failed (1):** and **Not done (1):** are never counted headings because countedLabelHeading is ^unable to; the two fallbacks with no first-person opener; and "the rename is already done" over-fires on both trees. Pre-existing, filed under things I am not asking you to fix here.

The ask

Narrow, and it is the same sentence as the comment you already wrote: after a bounded inability, treat whatever follows in that sentence and the next as the consequence, whichever connector introduces it, and release only on the affirmative allow-list or a topic shift. That makes explicitConsequenceBoundary unnecessary rather than longer. For the elided scan, match "never" or "did not" followed by any verb; enumerating verbs is the deny-list shape in a smaller box.

Keeping request changes for the six swallows, because base catches every one of them and this is the safety direction. The structure is right now, this is the last word list in the path, and I will re-run all fifty strings the moment it moves.

Self-review of the requested-change fixes at 2f3d28cdaea06e35b681595ed9f03bc4e6784709, based on current main 6937a309cf00825572210a7610a1f3ea8b74c2f9. The scoped completion-classification findings are addressed.

What changed

  • Removed the connector allow-list as the gate for bounded-observation consequences. Once an inability introduces a same-sentence or next-sentence consequence, it now remains incomplete by default; only an affirmative result or an explicit topic shift releases it.
  • Changed subject-elided missed work from a hand-maintained action list to the structural forms never <verb>, did not <verb>, and didn't <verb>, so unlisted actions such as touched and land cannot bypass the guard.
  • Recognized leftover as an absence qualifier, preserving the affirmative cleanup result.
  • Preserved exhaustive search evidence such as after carefully reviewing all registration paths as a completed observation, while a failed exhaustive attempt remains incomplete.

Regression proof

Before the production fix, the expanded end-to-end completion-gate matrix failed all six reported blocker examples plus the affirmative cleanup control. After the fix:

  • go test ./internal/agent -run '^TestCompletionGateStructuralReviewerMatrix$' -count=50 — pass
  • go test -race ./internal/agent -count=1 — pass
  • isolated HOME / file credential store go test -p 1 ./... -count=1 — pass
  • make fmt-check — pass
  • go vet ./... — pass
  • go build ./... — pass
  • go run ./cmd/zero-release build — pass
  • go run ./cmd/zero-release smoke — pass
  • Windows amd64 compile of ./internal/agent — pass
  • make vulncheck — pass, no vulnerabilities found
  • git diff HEAD^ --check — pass

make lint-static reports four advisory QF findings in internal/installtest/workflow_permissions_test.go, internal/proxydial/proxydial.go, and internal/tools/web_fetch.go. Those files are byte-identical to live main for this branch and are outside this two-file fix.

No dependency, external service, or third-party integration changes are included.

These checks were rerun on the exact final head. No evidence-backed defects found in this reviewed fix scope. Native Windows execution was not performed locally; remote CI and independent re-review must cover this head. This is a self-review, not an independent approval.

Re-checked at 2f3d28cd against the merge base (main at 6937a309), same harness, and this time with a third ring on top of the fifty strings from the earlier rounds: connectors beyond the second ring, elided forms with a verb phrase rather than a bare verb, affirmative results on nouns no list names, the new exhaustive-search release in both directions, and the new "leftover" qualifier placed where it must not release a stated failure.

The structure is right now. boundedObservationHasUnresolvedConsequence keeps a same-sentence or next-sentence consequence incomplete unless something affirmatively releases it, with no connector list in front of it, and the elided scan matches never, did not and didn't before any verb. Every third-ring connector fails closed ("which means", "hence", a sentence break, a bare "and", "so that"), every verb phrase does too ("never got to it", "did not manage to apply it", "didn't get around to the change"), and the exhaustive-search release goes the right way in both directions: "after carefully checking every caller ... the deletion is safe" is complete, "after tracing all the registration paths I could not find where the flag is set, so the bug remains" is not.

Sixty-eight strings, head against base:

base this branch
swallowed (false complete) 9 8
over-fired (false incomplete) 1 4

Every swallow on this branch is also a swallow on base, so no false complete is new here, and one of base's is fixed ("could not find any leftover callers, but the build is still broken" is incomplete now). The seven regressions from my last round are gone.

The three new over-fires are the cost of the inversion I asked for, and the direction I said I would take:

I could not find any stale entries; the sweep is complete.           INCOMPLETE
I could not find anything else to change; everything is in order.    INCOMPLETE
I could not find any leftover entries; the cleanup is complete.      INCOMPLETE

affirmativeObservationConsequencePattern keys the release on a noun list, and "sweep", "in order" and "entries" are not on it ("references" is, which is why the same sentence with "references" passes). A false incomplete costs a turn; a false complete ships unfinished work saying it is done. I would rather grow that one affirmative list over time than have the deny-list back, so I am not asking for anything here, only noting that this is now the only list in the path and it will want the odd word added as reports come in.

Not on this PR, for the record. Base and head both swallow "I could not find any leftover references, so it remains unfixed": the absence object wins over the stated failure because "remains unfixed" is not in unambiguousFailureStates (it has "unfinished" and "unresolved", not "unfixed"). Your own rule that an explicit failure state outranks an absence object is the right one and this is a gap in its vocabulary, so it is a small follow-up rather than a blocker, and it predates this branch. The other pre-existing ones are unchanged: headings not spelled "Unable to", and fallbacks with no first-person opener.

Approving. Thank you for doing it as an inversion rather than a longer list; the third ring is what shows the difference.

lgtm at 2f3d28cd. The inversions landed the way Vasanthdev asked — consequences stay incomplete by default with no connector list in front, and the elided scan matches never/did not/didn't before any verb. Every remaining over-fire is the safe direction, and nothing swallows that base catches.

Approving.
