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 and markers for inability, absence findings, tool availability, explicit failures, and blocked work. Observation findings require an "any" qualifier and an allowed absence object.
Sentence-level incompletion detection
internal/agent/guardrails.go
selfReportedIncompletion now applies failure precedence, sentence lookahead, topic-shift handling, counted-label filtering, and conditional tool-grant exemptions.
Incompletion regression coverage
internal/agent/guardrails_false_admission_test.go, internal/agent/guardrails_test.go
Tests cover honest caveats, tool limitations, blocked objectives, failure polarity, sentence boundaries, impersonal inability, exhaustive findings, counted headings, and genuine admissions.

Estimated code review effort: 4 (Complex) | ~45 minutes

Merge Risk: 🟡 Moderate · up to 1a6e9

The revised detector narrows several allowance patterns, but the current head can still treat admissions of guessing or fabrication as complete and can flag successful reports that use ordinary completion phrases. These are concrete correctness defects in reported results, so merge should wait for the exemption and phrase-matching fixes with regression coverage.

@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.

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_false_admission_test.go#L217-L237: add success-form cases using as requested and what was asked to the non-admission table.

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.

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.

@jatmn The current-head classifier findings are addressed as one clause-local precedence repair at eae209e.

Shared repair

  • Capability exemptions now skip only the specific tool-caveat inability, never the whole sentence.
  • A later inability starts a new scope, so it cannot borrow an earlier delivered fallback.
  • Substitute delivery now requires a completion-bearing verb in the relevant clause; bare location text such as an error being in the answer is not delivery.
  • Attempt and delivery order is preserved, so an earlier failed attempt does not erase a later completed fallback.
  • Counted labels exempt only a standalone heading or markdown bucket; same-line prose/admissions remain inspectable.
  • Consequence parsing starts after the matched inability, keeps weak separators inside a negated that-proposition, and recognizes causal because/since abandonment.

Regression proof

  • Added end-to-end completionPolicy matrix for seven incomplete and seven complete clause/polarity cases.
  • Applying only that matrix to old head 7906c00 failed 10 cases: all seven false completions and three false incompletions.
  • Current head passes the matrix, all internal/agent tests, and internal/agent race.

Repository validation

  • fmt, vet, release build, smoke, static analysis, govulncheck, diff check: PASS.
  • Full repository suite: every package passes except the same two internal/cli doctor tests that reproduce on clean current main 1b5db17.

Merged current main. No dependency or third-party integration change. Please rereview the current head.

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

Findings

  • [P1] Do not let a fallback activity mask a stated incomplete result
    internal/agent/guardrails.go:426-447, 990-993
    The new clause-local fallback path treats any matching alternative marker plus a generic completion verb as proof that the unavailable operation was successfully replaced. In particular, deliveredAlternativeAfter accepts I checked ... by hand, and the third exemption at line 992 immediately continues before the normal blockedWorkMarkers / unambiguousFailureStates handling runs. A final response such as I could not run the tests because no test tool is available, so I checked the style by hand, but the tests remain unverified. therefore reaches CompletionComplete: the tool caveat and style check match the exemption, while the explicit admission that the required tests were not verified is never considered. This is a root-cause issue in the exemption's evidence model: it uses an unrelated substitute activity as evidence that the failed objective was delivered, then makes that exemption terminal. Please make completion evidence objective- and scope-aware: a fallback should exempt only the inability it actually completes, and an explicit blocked/unverified outcome in that same inability scope must take precedence. Preserve legitimate capability footnotes and genuine completed read-only/bookkeeping alternatives; add regression coverage for both the blocked-outcome case and a valid substitute-delivery case.

  • [P2] Inspect the content of counted-label bullets before suppressing them
    internal/agent/guardrails.go:870-879, 912-915
    countedLabelSentence classifies a fragment as a Markdown bucket whenever the counted heading is followed by - , and selfReportedIncompletion then skips the whole fragment. That makes the label parser suppress more than its intended label. For example, **Unable to verify (1):** - I could not complete the audit; the work remains unverified. matches the heading expression, has a - remainder, and is discarded before either i could not complete or remains unverified can be classified; the run can consequently finalize as complete. The nearby comment says prose or another admission on the same line must be inspected, but the current predicate has no way to distinguish a benign bucket entry from an admission-bearing one. Please separate label recognition from content suppression: exempt only the heading syntax and run the attached bullet text through normal admission detection (or otherwise prove that the attached entry is not an admission). Keep standalone headings and benign counted finding bullets exempt, and add paired regression tests showing that a benign label remains complete while an admission inside its bullet is incomplete.

@jatmn Addressed the current-head review in 0cf06b53.

  • Fallback evidence is now objective- and scope-aware. A completion marker such as “by hand” is no longer enough by itself. The failed operation and substitute must share a deliberately bounded operation class, or the fallback must explicitly refer back to that recognized operation with “it”. Thus checking style cannot satisfy an inability to run tests, while the existing formatter → “checked it by hand” and plan → “wrote it into this answer” cases remain valid.
  • Blocked outcomes outrank all tool/fallback exemptions in the same inability scope. This covers unverified, unresolved, unfinished, handed-off, and related blocked-state markers.
  • Counted labels no longer swallow their bullet. Only the heading syntax is removed; same-line bullet content is sent through the normal admission classifier. Standalone headings and benign finding bullets remain complete.

One evidence nuance: the exact sentence ending “the tests remain unverified” was already caught by the earlier unambiguous-consequence guard on eae209e8. I still retained it in the matrix. The demonstrated pre-fix hole was the broader root class: eae209e8 classified both an unrelated style fallback and the same fallback followed by a handoff as complete. The new regressions fail on that old head and pass on 0cf06b53; the admission-bearing counted bullet also fails on the old head.

Validation:

  • full internal/agent tests and focused race run pass
  • formatting, vet, release build, smoke, static analysis (0 issues), vulnerability scan, and diff hygiene pass
  • full repository suite passes except the same two internal/cli doctor failures independently reproduced on current main

No dependency or third-party module changes. Please rereview current head 0cf06b53.

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

Findings

  • [P1] Do not treat an available tool as a harmless capability caveat
    internal/agent/guardrails.go:322
    The grant marker list includes positive availability forms, including tool available, tool is available, and tool was available. The grant-context and direct-caveat checks accept any one of those markers after an inability stem in the same clause; they never require the tool to be unavailable. The limited-plan exemption has the same polarity defect. A final answer that says it could not run a test tool available in its toolset, or could not record a plan while update_plan is available, therefore reaches an exemption. With no separate blocked-state marker, the classifier returns no reason and the completion policy finalizes the admitted failure as complete.

    Address the root cause by giving capability-state parsing one explicit contract: distinguish unavailable or grant-limited capability statements from positive availability, then use that predicate consistently for every exemption. Add regression cases for positive availability beside the existing read-only, missing-tool, and contracted-unavailable cases so later marker changes cannot invert that polarity.

  • [P1] Do not let a fallback for one operation complete a multi-operation failure
    internal/agent/guardrails.go:478
    The alternative-delivery path passes all words between one inability stem and its fallback clause to its operation matcher. That matcher returns after its first shared operation group. In a report that says it could not run tests or deploy a release because no tools are available, but checked the tests by hand, the fallback matches test. The same preceding scope also contains deploy and release, but that unfinished work is ignored after the early return. The alternative exemption skips the sole inability stem, and no later stem remains to make the completion policy return incomplete.

    Address the root cause by representing the failed operations covered by an inability as obligations, rather than using an existential keyword match over the whole clause. Either split coordinated failures before evaluating alternatives or require substitute evidence for every recognized failed operation. Keep the valid one-operation fallback behavior, and add paired coverage with one covered and one uncovered operation in both orders.

  • [P1] Apply the next-sentence blocked-state check before a tool exemption
    internal/agent/guardrails.go:968
    The classifier builds blocked context from the current and following sentences, but evaluates it only after direct-tool, limited-action, and alternative-delivery exemptions. Each exemption can skip classification first. A response that says it could not record a plan because update_plan is unavailable, followed by a sentence that the task remains incomplete, takes the limited-action exemption for the first sentence. The following explicit incomplete state has no inability stem of its own, so it is never classified and the whole response finalizes complete. The same ordering applies to a delivered fallback followed by an explicit handoff or unresolved outcome.

    Make scope and precedence explicit: before making an exemption final, evaluate whether the matched inability plus its permitted following consequence says work remains blocked. Keep that guard within the existing consequence and topic-shift boundary so an unrelated follow-up sentence cannot turn a valid capability footnote into an incomplete run. Add paired same-sentence and next-sentence blocked-state tests, plus an unrelated-topic control.

Addressed all three current-head findings in ff1811b.

  • Split capability recognition from capability polarity. Positive availability remains locatable but only an explicit unavailable/grant-limited state can grant an exemption; possession-denial and update_plan-unavailable forms have explicit handling.
  • Reworked fallback matching from “any shared operation” to obligations: every recognized failed-operation group must be covered by the delivered fallback. A singular pronominal fallback is accepted only for one failed operation.
  • Applied same/next-sentence blocked-state precedence before every tool/limited/fallback exemption, retaining the existing topic-shift boundary so unrelated follow-up text does not poison a valid completion.

End-to-end completion-policy regressions cover positive availability, both multi-operation orders, same/next-sentence blocked states, the valid single-operation fallback, unavailable update_plan bookkeeping, and an unrelated-topic control.

Validation: gofmt, diff check, full internal/agent tests, focused race tests, go vet, and go build ./... pass. No dependency or third-party integration changes. Please re-review current head.

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

Findings

  • [P1] Do not exempt a failed operation merely because its unavailable tool appears later in the same clause
    internal/agent/guardrails.go:573
    The new toolCaveatAt exemption is intended for capability footnotes such as an unavailable update_plan tool that was not required for the completed task. It currently also exempts a failed operation when the capability phrase is expressed with an unlisted connective. For example, I could not run the migration with no migration tool available. leaves clauseContaining with the entire sentence because with is not a structural boundary. The later tool available marker and no migration tool available polarity then satisfy toolCaveatAt, while no alternate delivery is required on this exemption path. The only I could not admission is skipped, so completionPolicy.evaluate returns CompletionComplete and the headless loop finalizes a run which explicitly says the migration was not run.

    Please address the root cause by making the exemption prove that the inability itself is a harmless capability footnote rather than inferring that from an unavailable-tool phrase elsewhere in its clause. In particular, do not rely on a growing list of connective spellings: preserve the capability-only update_plan/read-only cases, but require explicit substitute completion (or an otherwise bounded bookkeeping action) before an inability to run a substantive operation can be exempted. Add regression coverage for non-punctuation formulations such as with no … tool available and when no … tool is available, alongside the existing causal and punctuation variants.

  • [P1] Require fallback evidence to satisfy the failed operation, not just share its keyword
    internal/agent/guardrails.go:513
    deliveredAlternativeAfter accepts a fallback whenever it has a delivery verb and marker such as manually; alternativeMatchesFailedWork then considers it equivalent when both clauses contain a term from the same coarse group. Consequently, I could not run the migration because no migration tool is available, so I wrote the migration plan manually. is accepted: both sides match the migration group, although writing a plan does not execute the migration. This skips the admission and lets the headless completion path report success. The same root problem applies to other same-group non-substitutes, such as checking test documentation after being unable to run tests.

    Please fix the root cause by modeling the obligation that failed separately from incidental subject vocabulary. A fallback should clear an inability only when it demonstrably completes the failed operation (or a documented equivalent), not when it merely discusses, plans, documents, or reviews that operation. Keep valid narrowly scoped alternatives—such as the existing formatterchecked it by hand and plan → wrote it into this answer cases—but add paired regressions for same-keyword non-substitutes, including migration plan/report/documentation and test documentation/style, so future group expansion cannot reintroduce this false completion.

Addressed the current-head completion-policy findings and completed a full contract review.

  • Capability footnotes no longer exempt substantive failures under "with no ... tool available" / "when no ... tool is available" wording.
  • Fallback evidence must now prove that the failed operation itself completed; plans, reports, documentation, and style-only changes do not substitute.
  • Negated or incidental operation wording is rejected.
  • Added focused positive and negative regression coverage, including cases that failed on the prior head.

Validation:

  • go test ./internal/agent -count=1
  • go test -race ./internal/agent -count=1
  • repeated focused completion/admission regressions
  • format check, vet, release build, smoke test, static lint, and vulnerability scan

The full repository test run passes apart from the same two host-dependent local doctor tests (TestRunDoctorFormatsRedactedProviderDiagnostics and TestRunDoctorConnectivityProbesProvider), which are unchanged and outside this diff. No dependency or third-party integration changes.

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

Overall guidance

These findings are separate failure paths, but they come from the same design problem: the detector is deciding whether work completed by combining independent substring matches over a sentence. It has lists for inability stems, success-negation prefixes, absence objects, tool/capability wording, clause boundaries, fallback markers, action groups, and blocked states. Each list can identify useful vocabulary, but none by itself establishes the relationship the completion exemption needs to prove:

  • whether the negated verb describes a successful observation or failure to produce the requested deliverable;
  • whether an unavailable-tool phrase is a harmless note about an unused capability or the reason substantive work could not be performed;
  • whether later text completed the same failed operation, merely mentioned it, or completed only part of it.

The current control flow makes that distinction critical. Once an exemption branch matches, it continues past the matched inability. That means a false positive in an exemption does not merely lower confidence—it converts an explicit admission into CompletionComplete. Adding individual terms or connectors can make a supplied sentence pass, but it cannot reliably preserve those relationships across another ordering, connective, object, or scope qualifier. That is why the review keeps surfacing opposite-polarity cases after prior point fixes.

Please address this as one bounded classifier repair rather than another expansion of the marker lists. This does not require a general natural-language parser. A practical shape is:

  1. Normalize punctuation once and split each supported sentence into clause spans while preserving offsets and separators.
  2. For the matched inability, identify its failed operation and scope. Keep the action, object, and qualifiers together—produce a report, run the full test suite, and record a plan are different obligations.
  3. Classify a capability statement, successful absence, blocked outcome, and alternative delivery only within the relevant clause/span. A capability note should be exempt only when it is itself the harmless statement or when a bounded substitute proves completion.
  4. Make exemptions positive proofs, not absence of a known bad marker. A successful negative finding needs both a supported observation verb and an object whose absence is the result. A fallback needs evidence it completed every failed obligation at the required scope.
  5. Apply precedence before the continue: direct current-work failure, blocked outcome, or unproven substitute must win over an allowance. Preserve the explicitly intended cases—read-only bookkeeping notes, successful negative findings, and actual manual equivalents—through paired positive and negative tests.

Build the regression corpus as a table of semantic pairs, exercised through completionPolicy.evaluate as well as helper-level tests. For each supported class, cover the success case and its closest failure counterpart: observation versus requested production; unused capability versus inaccessible substantive work; completed substitute versus attempted, documented, reported, unrelated, partial, or multi-operation substitute; and simple versus qualified scopes such as smoke test versus full suite. This will make the contract reviewable and prevent another round where the next natural phrasing simply falls between independently maintained lists.

Findings

  • [P1] Do not treat a failed production as a completed negative finding
    internal/agent/guardrails.go:198-214, 1227-1235
    The new produce any success prefix turns a direct failure into an allowed negated finding. For I could not produce any report., the inability loop reaches produce any; hasAnyPrefix accepts it, while strongAbsence rejects report because it is not an allowed absence object. The final condition only turns that non-strong result back into an admission if a second, redundant blocked-work marker is present. Because this sentence has none, selfReportedIncompletion returns no reason and the headless path finalizes it as success.

    The root cause is that successNegationTails establishes only the shape of a negative statement, while strongAbsence establishes whether its object makes absence a successful result—but the final decision lets the first predicate win when the second fails. Keep the legitimate observation forms, but make the success exemption require a recognised successful-absence proposition. In particular, a failure to produce the requested output must fall through to the ordinary inability result without requiring extra words such as unverified or blocked. Add paired tests for successful observations (could not produce any crash) and failed requested output (could not produce any report) so the verb family cannot regress by object.

  • [P1] Do not exempt a substantive access failure as a capability footnote
    internal/agent/guardrails.go:692-707
    toolCaveatAt exempts any I don't have stem when a tool marker occurs later in the same structural clause. It does not establish that the stem is merely the harmless capability note that this branch is meant to permit. With I don't have access to the repository with no read tool available., with is not a structural boundary, so clauseContaining returns the whole sentence. The later tool available marker is found, the only inability is skipped at the exemption branch, and no fallback or completion evidence is required. The completion gate consequently accepts a run that explicitly lacks the access needed to do its work.

    The root cause is relationship-free scope: membership in the same clause is being used as proof that an inability is a harmless footnote. Extending the boundary list one connective at a time would leave the same defect at every unlisted formulation. Instead, make this exemption prove its narrower contract: either it is a direct, capability-only grant note such as the supported update_plan/read-only case, or bounded substitute work demonstrably completed the affected bookkeeping action. A substantive inability to access, inspect, run, edit, or otherwise perform work should remain an admission unless that proof exists. Add paired tests for the supported capability footnotes and for unavailable repository, file, credential, service, and tool-access failures expressed with both punctuation and ordinary connectives.

  • [P1] Require fallback evidence to complete the same full obligation
    internal/agent/guardrails.go:489-601
    The fallback exemption is still based on lexical overlap instead of proof that the failed work was completed. deliveredAlternativeAfter returns true for did not need without linking it to the failed operation. In fallbackCompletesObligation, the format/review/write/document/plan groups take the default return true as soon as the fallback repeats a group term; the test branch accepts a test action without retaining the failed scope. Consequently, an unrun migration plus I did not need the formatted output, an unapplied edit plus I reported the change manually, formatter documentation after failing to format code, or manually testing only a smoke test after failing the full suite can all skip the inability and finalize as complete.

    The root cause is that the classifier models related vocabulary rather than a completed obligation. A substitute should clear an admission only when it is tied to the same failed operation and covers its required scope; mentioning, planning, documenting, reporting, or partially checking that operation is not an equivalent. Represent the failed operation (including coordinated operations and qualifiers such as full suite) separately from the fallback, then require completion evidence for every failed obligation before granting the exemption. Preserve the valid narrow cases such as writing a plan into the answer when only planning was unavailable, or manually checking a formatter result, and add opposite-polarity tests for unrelated not needed, reports/docs/plans, partial suites, and multi-operation failures.

Findings

  • [P1] Do not let a capability footnote skip a coordinated objective failure
    internal/agent/guardrails.go:678-700, 1155-1159
    I don't have a write tool available, and I did not complete the task. is finalized as complete. The first I don't have claim is restricted to the capability clause, so hasObjectiveFailure cannot see the coordinated second clause; capabilityOnlyToolFootnote then returns true. The later I did not complete matches neither an inability stem nor a high-signal self-report phrase, so no subsequent pass can reverse that exemption. This is PR-introduced: the base classifier flags the possession-denial stem instead.

    The root cause is making a local capability exemption terminal while final-text failure evidence can occur in a related clause. Before accepting a capability-only exemption, account for an explicit objective-failure outcome in its permitted sentence/consequence scope. Keep the narrow read-only and update_plan footnotes working, but add paired tests for a harmless capability note, a same-sentence coordinated failure, and an unrelated later statement.

  • [P1] Carry a next-sentence blocked result through the strong-absence exemption
    internal/agent/guardrails.go:1149-1153
    I could not find any bugs. The fix remains unverified. returns complete. selfReportedIncompletion builds blockedContext from the current and next sentence specifically to recognize a separated consequence, but the strong-absence branch bypasses that context and reads only reportedConsequence from the first sentence. With no same-sentence separator, it exempts the inability; the second sentence has no inability stem and is never reclassified. This is an incomplete claimed fix: the PR adds and documents next-sentence blocked-context handling to stop an allowance from swallowing an admission, but the strongest absence form bypasses it.

    The root cause is divergent precedence for strong and non-strong negative observations. Apply the existing bounded next-sentence consequence policy before finalizing a strong-absence exemption, retaining carriesTheConsequence so a topic-shifted, out-of-scope, or unrelated follow-up does not turn a valid negative finding into an incomplete run. Cover both the explicit-unverified case and the existing unrelated-topic controls.

  • [P1] Apply the tool-limitation blocked-state check across its permitted next-sentence consequence
    internal/agent/guardrails.go:1246-1249
    No write tool is available. The change remains unapplied. also returns complete. The direct unavailable-tool path calls reportedConsequence(sentence, 0), which can only inspect the first sentence; it therefore sees no state. The second sentence has neither a tool predicate nor an inability stem, so it cannot independently produce an incomplete decision. This is another incomplete claimed fix: the PR adds this direct tool-limitation check to catch unapplied/unverified outcomes, but only for a same-sentence spelling.

    The root cause is a second consequence path that does not use the classifier's already-built bounded next-sentence context. Use one scoped consequence/blocked-state policy for both inability claims and direct unavailable-tool statements. Preserve the current same-sentence cases and capability-only notes, and add tests for same-sentence, next-sentence, and explicit topic-shift forms.

  • [P1] Do not treat a semicolon-separated unresolved result as part of a negated that proposition
    internal/agent/guardrails.go:991-1004
    I could not find any evidence that the fix works; the fix remains unverified. is accepted as complete. strongAbsence correctly recognizes that finding no evidence is normally a valid negative observation. But once reportedConsequence sees that, it skips every later non-causal boundary—including ; —and returns no asserted outcome. The strong-absence exemption therefore never sees remains unverified, despite it being a separate, explicit clause. This is an incomplete claimed fix in the PR's new negated-proposition parser.

    The root cause is treating all post-that non-causal boundaries as though they remain embedded in the negated proposition. Distinguish sentence/clause terminators from wording that can remain inside that proposition: at minimum, a semicolon must begin a reported outcome here. Preserve the intended I could not find any evidence that the issue is unresolved. case, and add paired tests for an embedded that state and a semicolon-separated state.

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

Findings

  • [P1] Preserve the requested deployment target when accepting a fallback
    internal/agent/guardrails.go:576-588, 1178-1195
    I could not deploy the release to production because no deployment tool is available, so I deployed it to staging manually instead. is accepted as complete. The fallback reaches the deploy group, and fallbackCompletesObligation accepts its first-person deployed action. But fallbackCoversRequiredScope only preserves test-suite and repository-wide qualifiers, so it drops the material production target and concludes that a staging deployment completed the failed obligation. A headless run can therefore finalize successfully after explicitly not performing the requested production deployment.

    The root cause is that fallback equivalence is modeled as an operation match plus a small fixed list of scope phrases, rather than preserving the material qualifiers of that operation. Keep target/environment qualifiers attached to the failed obligation when deciding whether an alternate action completes it. A regression matrix should distinguish production from staging (and analogous target-specific operations) while retaining valid alternatives that truly satisfy the same target.

  • [P1] Restrict the capability-footnote exemption to capability-only text
    internal/agent/guardrails.go:678-700, 1178-1189
    The terminal footnote exemption only validates text before its first tool-capability marker. For I don't have write tools available to modify the production configuration., between is only write , so it passes the denylist and returns true without considering to modify the production configuration. Likewise, in I don't have a browser tool available, so the required UI was never inspected., the first clause is exempted and the passive second clause does not contain a second first-person inability stem or a recognized blocked-state marker. Both reports are consequently accepted as complete even though they explicitly state that required work was not performed.

    The root cause is making a local capability check terminal before evaluating the rest of the report's obligation and outcome. Restrict this exemption to an actual capability-only footnote; if following text names the required operation or an unmet result, continue through the ordinary incompletion checks. Preserve the narrow read-only and update_plan caveats, and add paired tests for a harmless toolset note, an operation following the tool phrase, and a passive missed-result consequence.

All six blocking items across the three reviews are closed, and I checked each rather than taking the commit messages for it. Still requesting changes, because the new allowance machinery re-opens the same class in the other direction.

Everything below was driven through agent.Run(ctx, ..., Options{RequireCompletionSignal: true}) into completionPolicy.evaluate and selfReportedIncompletion on both trees, not through the helpers. No guardrail or completion test skips on this platform.

Closed

Mine. toolCaveatIsTheStatement is gone. capabilityOnlyToolFootnote at guardrails.go:721 now scopes to the clause, requires a possession-denial stem, requires the marker to follow that stem, and rejects on clause boundaries and operation words. All six reversed-order phrasings I gave are INCOMPLETE at head, and both controls are unchanged. The comma, paren and "and"-inside-the-noun-phrase case is closed by containsClauseBoundary.

@anandh8x. causalExcuseMarkers is gone repo-wide, zero grep hits, so the exemption is structural rather than a phrase list. The semicolon, colon and dash forms are all INCOMPLETE.

@jatmn. Your exact string, "...deployed it to staging manually instead", is INCOMPLETE, and the same-target alternative you asked to keep stays COMPLETE. Both strings from your second P1 are INCOMPLETE, and both footnotes you asked to preserve still pass.

The widening: seven cases where head says COMPLETE and base says INCOMPLETE

1. The new boundedNegativeObservationTails entries swallow bare admissions (guardrails.go:1237). "I could not find the root cause." / "I could not locate the migration script." / "I was unable to determine where the regression was introduced." All flagged by base, all waved through here. The "where" family is the intended fix and is pinned, but "find the", "find it", "find that", "locate the", "locate it" and "found the" also head the objective itself, and nothing in the sentence has to claim success to qualify. Base's successNegationTails contained none of these.

2. The same tails plus a consequence clause. exempt()'s weak branch at :1264 returns before the check the last commit added:

"I could not find any evidence, so the change was never applied."  -> INCOMPLETE
"I could not locate the file, so the change was never applied."    -> COMPLETE

Identical consequence, different tail. 704d2c1b strengthened only the branch these tails bypass. Adding && !hasReportedFailureConsequence(...) flips all ten realistic multi-sentence cases I drove and breaks nothing in the committed suite, so nothing pins the current behaviour either way.

3. harmlessToolLimitation lets the model self-certify past its own admission (:790-802). The gate is an OR, so possessionDenialStem alone satisfies it with no tool named anywhere, which is not what the doc comment says. "I do not have the network access I needed, but the task is complete." is COMPLETE, while the sibling stem "I could not run the migration, but the task is complete." is INCOMPLETE.

4. hasObjectiveFailure is inert across " and " (:852-853). "I do not have a write tool available in this context and could not complete the task." is COMPLETE; restore the dropped "I" and it is INCOMPLETE. capabilityOnlyToolFootnote uses the same boundary list to ignore the clause that this override needs to see, so one fact reaches two functions with opposite conclusions. That is the exact class the override exists to close.

5. countedLabelContent (:1191-1197). A bare heading such as "Unable to complete the task (1):" returns ("", true) and is skipped before hasObjectiveFailure is consulted. Worse, the same-line-bullet branch hands "Unable to verify (1): - the migration was never run" to a classifier with no stem and no tool context, so it is COMPLETE, while the identical text without the hyphen is INCOMPLETE. The verdict turns on a markdown hyphen the model wrote.

6. A fallback followed by an explicit failure is accepted. "...so I ran it manually instead, but it failed." is COMPLETE, as are the ". It failed." and "and it failed." forms. clauseBounds cuts on ", but ", so the failure text is never inspected, and neither "failed" nor "did not work" is in blockedWorkMarkers or unambiguousFailureStates. In-vocabulary consequences such as "but the migration is unverified" are caught, so it is the failure vocabulary that is short rather than the ordering logic.

7. @jatmn's target fix only holds for bare nouns (materialOperationTargets, :611-617). "...to our production cluster ... so I deployed it to our staging cluster manually instead." is COMPLETE, with failedTargets=[our] and fallbackTargets=[our]. A determiner or adjective eats the environment noun. Same for my/your/their, for "the main", and for prod to dev.

Smaller

capabilityOnlyToolFootnote screens the text before the marker with a deny-list and the text after it with an allow-list, so "I do not have the API key or the tools available in this session." is exempt while only "credentials" is caught. The phrasings are stilted, but that screen fails open for any noun nobody thought of, and this file's own comments elsewhere argue for allow-lists precisely because the branch grants an exemption.

guardrails_test.go:558-562 says "find the" and "confirm any" pre-date blockedWorkMarkers. They do not; this PR adds them. That comment is a large part of why the widening reads as pre-existing when it is not.

Discarded, because base does the same

"The migration was never applied because no migration tool is available." is COMPLETE on both trees. "I ran out of time, so the migration is unfinished." is COMPLETE on both. The "can not proceed" spelling missing from unambiguousFailureStates while present in blockedWorkMarkers is real drift, but head still catches the "cannot" spelling that base misses, so that one runs toward safety and I am not raising it.

Checked and correct

Build, vet, gofmt, GOOS=linux and GOOS=darwin all clean. Every guardrail, admission, fallback and completion-policy test passes, including TestCompletionAdmissionPreservesTargetsAndCapabilityOnlyScope and TestFallbackPreservesMaterialOperationTargets. The full-package failures on my box reproduce byte-identically on base, so no new failure is attributable to this PR. The exemptions @jatmn asked to preserve and the intended tightenings, including "I could not reproduce the crash, so the fix is unverified", are all pinned.

One structural note for whoever writes the fix: TestFallbackPreservesMaterialOperationTargets calls alternativeMatchesFailedWork directly rather than through the production path. It is covered elsewhere through selfReportedIncompletion today so it is not a live gap, but as this file grows, helper-level tests are exactly how a call-path regression hides.

Addressed all seven current-head false-completion classes in 3386d37:

  • narrowed bare negative-observation allowances and enforced failure-consequence precedence
  • required real unavailable-tool context and made capability subjects fail-closed by allow-list
  • detected coordinated objective failures, counted-label admissions, explicit failed/did-not-work fallback outcomes, and qualified deployment targets
  • added production Run(... RequireCompletionSignal: true) regressions plus completion controls

Validation: focused agent race tests; Windows compile-only check; full go test ./...; release build and smoke; static lint (0 issues); govulncheck (no findings); diff check. No dependency or third-party integration changes.

Please rereview the new head.

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

Findings

  • [P1] Do not treat a failed required action as a negative finding
    internal/agent/guardrails.go:1281
    The new find/locate/determine where allowance is unconditional. For I could not find where to apply the fix., successfulNegativeObservation returns true solely from the find where prefix, so inabilityClaim.exempt bypasses the ordinary i could not admission and the headless completion gate finalizes the run as successful. The base classifier rejects the same text. This has the opposite meaning from the motivating absence report (I could not find where X is set in production code): the first says that the agent could not perform a required action, while the second reports that a searched-for production occurrence does not exist. Address the root cause by making this exemption depend on evidence that the clause establishes an absence, rather than granting it from a verb prefix alone; keep the valid source-location absence case working and add paired regression coverage through Run(... RequireCompletionSignal: true).

  • [P1] Preserve the complete destination when accepting a fallback
    internal/agent/guardrails.go:581
    materialOperationTargets retains only the first non-determiner word after a target preposition. As a result, I could not deploy to the primary production environment … so I deployed to the primary staging environment manually instead. is accepted: both targets reduce to primary, and fallbackCoversRequiredScope declares the fallback equivalent. The same failure applies to destinations such as an internal production registry versus an internal staging registry. This defeats the PR's new target-preservation contract and lets a headless run report success after completing the wrong environment. Address the root cause by comparing the complete normalized destination (or another representation that preserves every material target component), rather than a single leading token; retain valid same-target manual fallbacks and cover both one- and multiword destinations.

  • [P1] Do not let a counted label erase a failed operation
    internal/agent/guardrails.go:1221
    countedLabelContent strips Unable to … (1): before classification. For Unable to deploy (1): - production deployment failed. and **Unable to verify (1):** - the migration did not run, the remaining bullet has neither an inability stem nor one of containsUnambiguousFailureState's narrow passive forms, so the scanner returns no reason and the headless gate accepts the run. The base correctly rejects the unstripped subjectless unable to admission; the new heading exemption introduces the gap. Address the root cause by retaining the heading context, or by applying a complete failure-consequence classifier to same-line bullet content before discarding it. Preserve ordinary counted audit headings and benign entries such as truncated-source claims, but add regression coverage for active missed work and generic operation failure as well as the existing passive forms.

Addressed all three current-head completion-gate findings in e168abb9.

  • Replaced the unconditional find/locate/determine where allowance with a bounded source-location observation that requires passive location evidence; I could not find where to apply the fix is now incomplete.
  • Preserve and normalize the complete multiword operation destination, so production/staging mismatches no longer collapse to the same leading token while same-target fallbacks still pass.
  • Keep counted-heading context when same-line content reports a generic failure or active missed work, covering failed deployment and migration-did-not-run forms.
  • Added production Run(... RequireCompletionSignal: true) regressions for each rejected admission and the valid same-target control.

Validation:

  • go test -race ./internal/agent
  • make fmt-check
  • make vet
  • go test ./... -count=1
  • release build and smoke
  • static lint: 0 issues
  • govulncheck: no vulnerabilities
  • Windows compile-only coverage for internal/agent

No dependency or third-party integration changes.
