@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 The headline is that you were right and the number is worse than "broad": 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 ( 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:
-
[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-markercontinuechecks onlyobjectiveFailureMarkers, so it bypasses the later blocked-work handling. Do not apply that exemption when the same sentence carries a blocked-work marker. -
[P1] An explicit
anyis not always a successful absence finding.I could not find any solution, so the migration remains unresolved.also returns no incompletion reason.strongAbsenceTailsunconditionally 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 everyfind anyprefix 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.

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 Your finding 1 was already fixed when you reviewed — your review is against Your finding 2 was live and is now fixed. Both carry the explicit 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 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 |

@Vasanthdev2004 @anandh8x — head 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 — 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: 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 You were right that the object cannot outrank the state. The absence protection exists for ownership and follow-up wording, where Same-sentence only, deliberately. A state in the next sentence may belong to another subject — @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 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, 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 @anandh8x — you caught the opposite polarity of the case I fixed one commit earlier, which is the part worth dwelling on: A successful negative finding, marked as an admission. What separates the two is position, exactly as you said. After a consequence boundary the state is being asserted; inside a 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. |

[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.
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. |

[P1] Do not exempt a failed operation merely because its unavailable tool appears later in the same clause
internal/agent/guardrails.go:573
The newtoolCaveatAtexemption is intended for capability footnotes such as an unavailableupdate_plantool 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.leavesclauseContainingwith the entire sentence becausewithis not a structural boundary. The latertool availablemarker andno migration tool availablepolarity then satisfytoolCaveatAt, while no alternate delivery is required on this exemption path. The onlyI could notadmission is skipped, socompletionPolicy.evaluatereturnsCompletionCompleteand 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.

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:
- Normalize punctuation once and split each supported sentence into clause spans while preserving offsets and separators.
- 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, andrecord a planare different obligations. - 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.
- 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.
- 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.

[P1] Do not treat a failed production as a completed negative finding
internal/agent/guardrails.go:198-214, 1227-1235
The newproduce anysuccess prefix turns a direct failure into an allowed negated finding. ForI could not produce any report., the inability loop reachesproduce any;hasAnyPrefixaccepts it, whilestrongAbsencerejectsreportbecause 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,selfReportedIncompletionreturns no reason and the headless path finalizes it as success.The root cause is that
successNegationTailsestablishes only the shape of a negative statement, whilestrongAbsenceestablishes 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 asunverifiedorblocked. 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
toolCaveatAtexempts anyI don't havestem 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. WithI don't have access to the repository with no read tool available.,withis not a structural boundary, soclauseContainingreturns the whole sentence. The latertool availablemarker 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.deliveredAlternativeAfterreturns true fordid not needwithout linking it to the failed operation. InfallbackCompletesObligation, the format/review/write/document/plan groups take the defaultreturn trueas soon as the fallback repeats a group term; the test branch accepts a test action without retaining the failed scope. Consequently, an unrun migration plusI did not need the formatted output, an unapplied edit plusI 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 unrelatednot needed, reports/docs/plans, partial suites, and multi-operation failures.

The fallback reaches thedeploygroup, andfallbackCompletesObligationaccepts its first-persondeployedaction. ButfallbackCoversRequiredScopeonly preserves test-suite and repository-wide qualifiers, so it drops the materialproductiontarget 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

ForI don't have write tools available to modify the production configuration.,betweenis onlywrite, so it passes the denylist and returns true without consideringto modify the production configuration. Likewise, inI 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.

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.

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.

The same failure applies to destinations such as an internal production registry versus an internal staging registry.

The base correctly rejects the unstripped subjectlessunable toadmission; 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.

I found issues that need to be addressed before this is ready.
Overall guidance
These are not five unrelated missing phrases, and I do not think another round of adding individual words to the existing lists will close the review. The repeated findings come from three shared structural problems in the classifier:
- An exemption consumes more text than its evidence proves. A capability-only clause, counted heading, or fallback clause can establish one narrow fact, but the caller then returns or continues past the whole inability. Failure evidence in a coordinated clause, in the heading that was stripped, or after the fallback is no longer evaluated.
- The failed obligation is reduced too aggressively. Fallback matching keeps a coarse action group such as
test,publish, ordeploy, plus a few hard-coded scope phrases and prepositional targets. It loses the direct object, coordinated duties within one group, broad quantifiers, and the result polarity. Once those fields are gone, different or partial work can look equivalent to the failed work. - The same relationship is reconstructed independently from vocabulary in several paths. Negative observations, blocked consequences, fallback outcomes, capability clauses, and counted labels each have separate marker/boundary lists. A phrase can therefore be recognized as a failure in one path and become invisible in another, or change classification solely because its connective, modifier, or formatting changed.
The fix does not need to become a general natural-language parser. A bounded repair can stay conservative:
- Treat each inability and each coordinated clause as a claim span. An exemption should clear only the span it proves harmless; scanning must continue through the rest of the sentence/report.
- Build one small failed-obligation representation before testing a fallback: operation class, material object, destination/environment, quantifier or required breadth, coordinated components, and outcome polarity. A fallback should exempt only when it affirmatively completes every material component of that same obligation.
- Centralize outcome polarity. Negated, attempted, partial, unsuccessful, crashed, or otherwise failed work must not become completion evidence merely because a past-tense action word appears.
- Preserve counted-heading context while classifying attached content. The heading and content have separate roles, but discarding either before their relationship is known recreates the same gap.
- Use one bounded consequence decision for strong and weak negative observations. It should identify whether blocked-state text is the result/cause of the search, not depend on enumerating each connective separately.
Please add paired end-to-end coverage through Run(... RequireCompletionSignal: true) for the structural matrix, not only helper-level tests or the exact strings below:
| Contract | Must remain complete | Must remain incomplete |
|---|---|---|
| Capability note | Direct update_plan/read-only capability footnote with no failed objective |
Same footnote followed by a coordinated, subject-elided required-action failure |
| Fallback identity | Same operation, object, target, breadth, and coordinated duties completed manually | Different object/target, a subset of coordinated duties, or smoke coverage substituted for every test |
| Fallback result | Affirmatively completed equivalent work | Negated, partial, unsuccessful, crashed, attempted-only, or otherwise failed substitute work |
| Counted label | Benign audit bucket whose attached content reports a finding | Attached content reporting that the counted operation was rejected or did not complete |
| Negative observation | Exhaustive absence finding with no blocked outcome | Search that found nothing because the run exhausted its time or otherwise remained blocked |
Those pairs should be mutation-checked through the production completion gate. In particular, reverting the relationship or scope fix—not merely deleting one marker—should make the opposite-polarity case fail. That is the evidence needed to avoid another round where a supplied sentence turns green but an equivalent ordering, object, modifier, or connective remains open.

internal/agent/guardrails.go:433-574
alternativeMatchesFailedWorkreduces the failed clause to one or more broad operation groups.fallbackCompletesObligationthen proves only that the fallback contains an action associated with each group, whilefallbackCoversRequiredScoperetains two enumerated breadth families and targets introduced by a short preposition list. The material object and multiplicity inside a group are not represented. As a result, this head accepts all four of the following as complete while the merge base rejects them: publishing release notes after admitting the package could not be published; publishingfor stagingafter an admittedfor productionfailure; running only unit tests after admitting unit and integration tests could not run; and running a smoke test after admitting every test could not run.Please address the obligation model rather than adding these nouns, prepositions, or quantifiers to more lists. Capture the material object, destination, required breadth, and every coordinated component before the fallback is evaluated, then require affirmative completion of the same complete obligation. Preserve the valid controls where the exact same object/target and full required scope were completed manually.

The problem is thatinabilityClaim.exemptthen treats that local result as terminal. The coordinatedcould not applyclause has no repeatedI, so it is not one of the outer scan's first-person inability stems; it also does not match the enumerated task/objective phrases used byhasObjectiveFailure. Nothing examines the explicit required-action failure after the capability clause is exempted.Please make exemptions span-local: exempt the capability clause, then continue classifying the coordinated remainder, including subject-elided inability forms governed by the same subject. Do not solve this by enumerating
apply,deploy, or other objective verbs inobjectiveFailureMarkers; the missing contract is continued clause scanning, and the existing directupdate_plan/read-only footnotes must remain complete. -
[P1] Require affirmative success from delivered fallback evidence
internal/agent/guardrails.go:433-438, 500-554, 687-699
The fallback path treats an action word as completion evidence without first establishing positive outcome polarity. The initial negative-form check omitsnever; the specific-action branches accept words such asdeployedwithout consideringunsuccessfullyorpartially; andfallbackPronounCompletesObligationcan match the substringdeployed itinsideI never deployed it. Failure handling after the fact is also vocabulary-limited. The head therefore finalizes a manual migration followed bybut it crashed,I unsuccessfully deployed it,I partially deployed it, andI never deployed it manually instead; the merge base rejects every case.Please decide success polarity once, before either the specific-action or pronoun path may satisfy an obligation. Only an affirmative completed action should count. Negated, attempted, partial, unsuccessful, crashed, or otherwise failed outcomes should remain admissions regardless of which verb or pronoun form they use. Keep the positive controls where equivalent manual work actually completed.

[P1] Keep the counted inability attached to operational failure content
internal/agent/guardrails.go:1235-1257, 1341-1349
**Unable to publish (1):** - registry rejected the request.is accepted as complete at this head, while the merge base rejects the subjectless inability.countedLabelContentremoves theUnable to publishheading. Becauseregistry rejectedis not incontainsFailureConsequence's narrow vocabulary, it returns onlyregistry rejected the requestas benign counted content;selfReportedIncompletionreplaces the sentence with that fragment, which contains no inability stem. The formatting operation has therefore erased the context that makes the operational rejection an admission.Please preserve the relationship between a counted heading and attached content until the content has been classified. A standalone or benign audit bucket should remain exempt, but attached text reporting that the counted operation was rejected or did not complete must retain the subjectless inability context. Adding
rejectedalone would leave the same defect at the next operational failure synonym, so the regression should prove the heading/content relationship rather than one vocabulary entry. -
[P1] Make blocked negative observations independent of connective spelling
internal/agent/guardrails.go:1113-1171, 1318-1325
The PR correctly catchesI could not find any issues because I ran out of time., but accepts the equivalentI could not find any issues due to running out of time.as complete.

Re-verified at e7054c3. Every verdict below comes from agent.Run with RequireCompletionSignal, on this head, on base, and on the 704d2c1 classifier I reviewed last time. My exact strings all fail closed now and the pins hold under reversion, so the fixes are real. But each closer is a word list, and the neighbouring phrasing reaches the same swallow while base catches all of it, so I am keeping request changes. jatmn and I are asking for the same thing, so one answer for both of us: the polarity and consequence gates need to be affirmative allow-lists, not lists of failure words.
Closed:
- Bare admissions through the bounded tails. "I could not find the root cause.", "I could not locate it." and "I could not find where to apply the fix." are all INCOMPLETE, the "where" controls stay COMPLETE, and restoring the old tail list fails the pinned test at completion_gate_test.go:246.
- The possession leg of harmlessToolLimitation, the adjacent "and could not complete the task" form, and the determiner-eaten targets. Each now has two independent layers, and each reversion fails its pin on the property line.
Open, all COMPLETE on this head and INCOMPLETE on base:
- The consequence vocabulary is closed. "I could not find where the flag is set, so the task is not done.", the same with "so the fix has not been applied.", and "I could not find the value being set, so I made no change."
- The surviving return in harmlessToolLimitation self-certifies any inability once the sentence mentions an unavailable tool. "I could not run the migration because no migration tool is available, but the task is complete." passes, which the function's own comment says it must not.
- The subject-elided scan needs the stem right after the connector, so one adverb defeats it. jatmn's own string with "therefore" inserted, "I don't have a write tool available in this context and therefore could not apply the fix.", passes.
- A counted heading with its bullet on the next line, the ordinary markdown layout. "Unable to deploy (1):" followed by "- production deployment failed." on its own line passes; the same text on one line is caught. The verdict that used to turn on a hyphen now turns on a newline.
- Fallback followed by an explicit failure is a deny-list. "I could not run the migration because no migration tool is available, so I ran it manually instead, but it timed out." passes. jatmn's ask, affirmative success from the delivered fallback evidence, is the fix; this head shipped the opposite.
Two new regressions from the three commits after 704d2c1, both fail-closed, both COMPLETE on base and on 704d2c1:
- explicitFailureConsequencePattern makes its subject optional, so the adjective counts. "I could not find any issues; the failed test in CI is a known flake." is INCOMPLETE here.
- activeMissedWorkPattern flips a read-only audit's ordinary next sentence. "I could not find any remaining issues. I did not modify any files." is INCOMPLETE here. Removing that pattern leaves every completion-gate test green, so nothing pins it and these flips are its only observed effect.

I found issues that need to be addressed before this is ready.
Overall guidance
I do not want to continue dripping one neighboring sentence per review round. The nine findings below are the complete verified set on the current head, but they are not nine unrelated vocabulary omissions. They come from five shared structural problems in the classifier:
- An exemption consumes more text than its evidence proves. A capability-only clause or a bare completion declaration proves, at most, one narrow fact. The caller then exempts the whole inability and stops before a coordinated failed-action clause is classified.
- Fallback success is inferred negatively.
fallbackOutcomeIsAffirmativeasks whether a small failure-word list is absent. That makes a past-tense verb look successful even when the fallback is counterfactual, timed out, cancelled, unfinished, or explicitly unsuccessful. - The failed obligation is reduced before equivalence is decided. Operation groups, a breadth boolean, and filtered component words lose distinctions such as full suite versus smoke test. Once that information is discarded, a different or partial substitute can look equivalent.
- Normalization destroys relationships that classification still needs. Sentence/newline splitting detaches a counted operational heading from the bullet that explains its failure, so neither fragment carries enough information to classify correctly.
- Outcome polarity is reconstructed independently from vocabulary. Negative observations, blocked consequences, and read-only statements are decided by separate regex/marker lists rather than by whether the later text is actually the outcome of the current inability. This creates both false success and false incompletion.
Please address those decision boundaries once rather than add the supplied words, modifiers, or punctuation to more lists. A bounded repair does not need to become a general natural-language parser. It can remain local to this completion classifier:
- Treat each inability and coordinated clause as a claim span. An exemption should clear only the span it proves harmless, and classification should continue through the remainder.
- Retain a small failed-obligation representation until fallback equivalence is decided: operation kind, material object, destination/environment, required breadth, and coordinated duties.
- Require positive evidence that the same obligation completed successfully. Negated, conditional, attempted, partial, cancelled, timed-out, or otherwise failed substitutes must never become completion evidence merely because an action verb appears.
- Preserve counted heading/content attachment through normalization and classify the relationship before discarding either side.
- Make one bounded consequence decision: is the failure/no-change text the asserted result of this inability, part of the proposition being negated, or a separate/topic-shifted statement?
For the next revision, please add paired end-to-end cases through Run(... RequireCompletionSignal: true), not only helper-level examples. Each structural fix should have both a must-complete and must-incomplete control, including reordered clauses, ordinary modifiers, punctuation/newline variants, equivalent outcome wording, and same/different obligation scope. Mutation-check the decision itself—for example, reverting span continuation, affirmative polarity, obligation preservation, or heading attachment—not merely deleting one newly added marker. That is the evidence needed to close this as one coherent fix rather than another exact-string round.
The positive contracts must remain intact: direct read-only/update_plan capability notes, genuinely completed same-obligation fallbacks, benign counted audit buckets, exhaustive absence findings, failure text inside a negated proposition, explicit topic shifts, and successful read-only reports.
Findings
-
[P1] Require affirmative success before accepting a fallback
internal/agent/guardrails.go:601-615
Current behavior:fallbackOutcomeIsAffirmativereturns true unless the fallback contains one of a finite set of negative/failure words. Both the specific-action and pronoun paths may then use a past-tense action substring as completion evidence. The production gate therefore acceptswould have deployed it,but it timed out,was cancelled,did not finish,was not successful, andwas incomplete; every example reachesCompletionCompleteon this head while the merge base rejects the original inability.Root cause and required outcome: absence of recognized failure vocabulary is not affirmative success. Decide outcome polarity once before either fallback-matching path can grant an exemption, and require evidence that the substitute action actually completed. Preserve positive controls where the same obligation was affirmatively completed manually. The regression matrix should cover conditional/counterfactual, negated, attempted-only, partial, cancelled, timeout, error, crash, and successful forms without making any one synonym the implementation boundary.
-
[P1] Preserve the required validation kind as well as breadth
internal/agent/guardrails.go:578-665
Current behavior:requiredBreadthreduces scope to a boolean.materialObligationComponentsthen discardsfull,suite, and the test operation words, leaving no failed component that distinguishes a full suite from smoke coverage.I could not run the full test suite ... so I ran a full smoke test manually insteadis consequently finalized as complete. Repeatingfullon the substitute does not make the validation equivalent.Root cause and required outcome: the failed obligation loses its validation kind before equivalence is checked. Retain enough identity to distinguish suite, integration, unit, smoke, package, object, target, and coordinated duties where they are material. A fallback should earn the exemption only when it affirmatively covers the same required obligation. Preserve the existing positive case where the full suite itself was run manually; do not solve this by special-casing the word
smoke. -
[P1] Continue scanning modifier-bearing coordinated failures
internal/agent/guardrails.go:837-889
Current behavior: aftercapabilityOnlyToolFootnoteexempts the first clause,hasUnexemptedSubjectElidedInabilitysearches only exactconnector + inability stemstrings.I don't have a write tool available in this context and therefore could not apply the required fixinserts an ordinary modifier, so the capability clause is accepted and the failed-action clause is never classified. The same sentence withoutthereforeis covered, which means verdict depends on modifier placement rather than meaning.Root cause and required outcome: the exemption is span-local but its caller treats it as terminal, and continuation scanning recognizes only one surface form. Exempt the capability span, then continue classifying coordinated text governed by the same subject, with or without an intervening modifier. Keep a direct capability footnote complete when no failed objective follows. Test exact, modifier-bearing, reordered, and separately punctuated forms through the production gate.
-
[P1] Do not let a completion declaration self-certify failed work
internal/agent/guardrails.go:951-969
Current behavior:harmlessToolLimitationreturns true whenever a later substring matchescompletedObjectiveMarkers, without showing that the admitted operation was unnecessary or completed another way.I could not run the migration because no migration tool is available, but the task is completetherefore passes. The model's conclusion overrides the concrete evidence in the same sentence.Root cause and required outcome: a bare completion assertion is being used as proof instead of being reconciled with the failed obligation. Limit this exemption to genuinely non-objective bookkeeping such as an unnecessary
update_planstep, or require affirmative equivalent delivery for the admitted operation. Preserve valid read-only and plan-tool caveats; do not enumerate migration/deploy/build verbs as special failures. -
[P1] Keep multiline counted headings attached to their failure content
internal/agent/guardrails.go:1380-1404,1540-1548
Current behavior:admissionSentencessplits on newlines beforecountedLabelContentruns. With ordinary Markdown—**Unable to deploy (1):**followed on the next line by- production deployment failed—the first fragment is dropped as a standalone counted heading and the second has no inability stem. The same words are rejected only when placed on one line, so formatting alone changes the completion decision.Root cause and required outcome: normalization discards the relationship before classification. Keep a counted heading attached to its following content long enough to decide whether it is a benign audit bucket or an operational inability whose entry reports failure. Preserve standalone/benign verification buckets and count-free subjectless admissions. Cover same-line, newline bullet, multiple-bullet, and harmless audit layouts through the production gate.
-
[P1] Bound negative-observation exemptions to their actual outcome
internal/agent/guardrails.go:1268-1317,1479-1500
Current behavior: the PR newly exempts boundedfind where ... is setandfind the ... being ...observations. The consequence path then recognizes only listed result phrases, soI could not find where the flag is set, so the task is not done,so the fix has not been applied, andI made no changeall finalize as complete here while the merge base rejects them. The bounded observation is valid only if finding the location was itself the completed task; these sentences explicitly say it was not.Root cause and required outcome: the classifier grants the observation exemption before establishing whether later text reports its blocked result. Make the consequence decision about the relationship, not a closed vocabulary: asserted blocked outcome versus text inside the proposition being negated versus an unrelated/topic-shifted statement. Preserve exhaustive findings such as
could not find any issues, negated propositions such ascould not find evidence that the issue is unresolved, and clearly separate follow-up work. -
[P2] Do not treat an adjectival
failednoun as the search outcome
internal/agent/guardrails.go:1313-1317
Current behavior: the subject inexplicitFailureConsequencePatternis optional. InI could not find any issues; the failed test in CI is a known flake, the adjectivefailedis therefore matched as if the report assertedit failed, and a legitimate negative finding is downgraded. The merge base accepts the same report.Root cause and required outcome: the regex recognizes a token rather than a failure predicate tied to the current claim. Require an asserted predicate with an owned subject/relationship while preserving real consequences such as
it failed,that failed, orthe operation failed. Add paired noun-phrase and predicate cases; do not special-caseknown flake. -
[P2] Do not infer blocked work from a read-only no-change statement
internal/agent/guardrails.go:1237-1244,1555-1564
Current behavior: the next-sentence lookahead appliesactiveMissedWorkPatternwithout establishing that modification was an obligation.I could not find any remaining issues. I did not modify any files.is marked incomplete even though no issue was found and no edit was required—the expected result of a completed read-only review. The merge base accepts it.Root cause and required outcome: no-change wording is treated as an unambiguous blocked state independent of the task/claim relationship. Require evidence that a mutating obligation remained unmet before treating
did not modifyas failure. Preserve real admissions such as a required fix remaining unapplied, while allowing read-only audits, no-op fixes, and explicit topic shifts. Test both same-sentence and next-sentence forms. -
[P2] Preserve singular recognized-object negative findings
internal/agent/guardrails.go:1071-1150,1468-1485
Current behavior: the PR removes the merge base's broadfind aallowance, but its replacement recognizes onlyfind anyobjects plus boundedfind the/find whereforms.I could not find a bug after inspecting every changed pathis now reported incomplete, although a completed search finding no bug is the same result as finding no issues. At the same time,I could not find a solutionmust remain an admission.Root cause and required outcome: grammatical number/determiner was changed without carrying the recognized-object distinction into the singular form. Apply the existing absence-object classification to valid singular results while continuing to reject deliverables such as solution, fix, or workaround. Do not restore the old unconditional
find aprefix; add paired recognized/unrecognized object cases at helper and production-gate levels.

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
mainon 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:
Some of the ten:
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, …).The motivating case still passes as a finding:
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
blockedWorkMarkersputs 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 currentmain.Part of #829.
