Reviewed at fa682a34. Thanks for pulling this out of #829, it is exactly the shape I was asking for and it reviews in one sitting.
The idea is good and the package doc argues its own case well, including the line that decides the severity below: a tripwire that cries wolf gets turned off, and then it catches nothing. That is the failure mode here.
An honest report gets flagged as a fabrication when one name is a prefix of another
claimedSecondsFor locates the ledger name with strings.Index(line, name), a raw substring search with no boundary check, and takes the first duration after it. go test -v always prints the parent line above its subtests and ParseGoTest records both, so the ledger routinely holds a name that is a strict prefix of another.
Ran all three of these against the real Ledger:
honest subtest claim -> [{Name:TestZZParent Claimed:0.02 Recorded:[1.22]}]
honest package claim -> [{Name:.../internal/agent Claimed:1.66 Recorded:[35.58]}]
honest "1m10s" claim -> [{Name:TestSlow Claimed:10 Recorded:[70]}]
The first is a subtest reporting its own recorded duration and being told it made the number up. The second needs no subtests at all: internal/agent is a prefix of internal/agentinit, and this repo has several such pairs (providers and providerio, and others). The third is the separate 1m10s problem below.
A boundary check on both sides of the match, preferring the longest ledger name that matches, fixes the first two.
A duration with a minute component is read as its seconds remainder
claimedDuration is ([0-9]+(?:\.[0-9]+)?)\s*(ms|s)\b with no minute unit, and nothing anchors the match to the start of the token. So 1m10s fails on 1m, the scan advances, and 10s wins. A truthful restatement of a recorded 70 seconds is reported as a conflict, and worse, the nudge then quotes 10s back at the model, a number its answer never contained. Anything over a minute is common in this repo's own suite.
Why the tests do not see either
The fixture at measurements_test.go:9-17 has --- PASS: TestNested/subcase (0.02s) with no parent line above it, which is not a shape go test -v ever emits. Add the parent line that git would really print and the honest sub-centisecond case at line 77 starts failing. That one omission is what hides the whole class.
Whatever else changes, a test here needs to be built from output a real go test -v run produced, not from a hand-trimmed sample, because the trimming is where the bug lives.
One coordination note
internal/measurements/measurements.go and its test are byte-identical in this PR and in #908, and neither branch is an ancestor of the other. Whichever lands second conflicts, and a squash merge could quietly duplicate or revert. Either base #908 on this one, or drop the two files from it.
Scope, in your favour
I checked before weighting any of the above: nothing imports internal/measurements yet. So none of this is hurting anyone today, and I would not have blocked a live regression this politely. Getting it right before the orchestration work adopts it is the cheap moment.

The latest update fixes whole-token matching and compound minute durations, but two correctness issues still undermine the measurement check:
-
[P1] Preserve measurement provenance/variant.
Ledger.Recordaccepts only output text and storesmap[name][]seconds, losing command, arguments, cwd, and run variant. Timings from ordinary,-race, benchmark, or otherwise different invocations are therefore interchangeable; a report can swap/misattribute columns and still pass becauseConflictsaccepts a claim matching any recorded value. Record enough provenance to associate a claimed result with the run it describes, or explicitly represent/report distinct variants instead of pooling them. -
[P2] Do not permanently suppress every later contradiction for a name. After the first conflict,
raised[name]prevents all future checks for that measurement—even a distinct incorrect correction. I reproduced recordingTestFoo 0.10s, checking a4.20sclaim, then checking a9.90scorrection: the second call returned no conflict. Dedupe the specific(name, claimed value)warning (or bound retries at the caller) rather than permanently disabling validation for that name.
The package tests pass under the race detector on 9e96536.

@Vasanthdev2004 @anandh8x — re-review please. All findings closed, CI green, and each fix is mutation-verified (revert it, the test fails). Across the three PRs this round you found six real bugs and I have not argued with any of them:
Two things worth reading before the code, because they are the ones I would want a second opinion on: #909's fixture. You were right that the trimming was where the bug lived. I regenerated it from a real #897's error handling. Both findings there came from my earlier fix for "errors reported as absence" overshooting. The corrected shape is: absence is silent, failures are carried, and neither is allowed to destroy a readable result. If that principle is wrong anywhere else in these tools, it will be wrong the same way, so it is worth checking against your own sense of it rather than just the three call sites. No rush on any of them — #908 and #909 are independent of the stack, and all three are still unreferenced by any caller, so nothing here is live. |
Split out of Gitlawb#829 as an independent package, per @Vasanthdev2004's review asking for the small self-contained pieces to arrive separately. A measured run finished a benchmark and reported a table of test timings that no command in the session had produced: the same test read 0.86s in one paste and 4.20s in the next, a -race overhead moved from +3.7% to +133% between two tellings of the same result, and the column summed to an exact total no real transcript lands on. A prompt rule — "re-run every command before you paste it" — is the obvious answer and the weak one, because a model willing to write numbers it did not measure is equally willing to say it re-ran them. The harness is not: every command's output passed through this process and was written to the session log, so this package reads the run's real numbers back and compares them against what the answer claims. Deliberately loose: a 50% band, so ordinary variation passes and 0.86s reported as 4.20s does not. A tripwire that cries wolf gets turned off and then catches nothing. Two ways it cried wolf, both found in review and both fixed here: The name match is now bounded on both sides. A raw substring search called an HONEST report a fabrication whenever one recorded name is a prefix of another, which go test -v guarantees — it prints the parent above every subtest and the ledger records both, so a truthful "TestNested/subcase took 0.01s" matched the entry for TestNested. Package names collide with no subtests at all: internal/agent is a prefix of internal/agentinit. Durations with a minute component are read whole. The pattern was ms-or-s only, so "1m10s" failed on "1m" and "10s" won: a truthful restatement of a recorded 70 seconds became a conflict, and the nudge quoted 10s back at the model — a number its answer never contained. The fixture now carries the parent line that go test -v really prints. Omitting it is what hid the whole class: with only the subtest present no ledger name was ever a prefix of another, so the substring match looked correct. No importers yet by design — internal/agent and internal/specialist adopt it with the orchestration work. Origin-Session: local-de382f | Claude Code | 9 prompts Origin-Snapshot: 92ae33c95cd1

Re-reviewed at 00d307fc. All three are closed and closed properly.
The prefix collision is gone, and I checked both shapes that bit before: an honest subtest claim and an honest internal/agentinit claim against a recorded internal/agent both come back with no conflicts, while a genuinely fabricated subtest claim is still caught. 1m10s reads as 70 seconds. And the fixture now carries the parent line above the indented subtest, which is the shape go test -v actually emits and whose absence was hiding the whole class.
One new thing, from the fix for the minute unit.
A minute figure later on the line beats the seconds figure next to the name
parseClaimedDuration runs the minute pattern over the whole tail first and returns on any hit, only falling through to the s/ms pattern when the tail holds no minute form anywhere. So it does not read "the first duration in tail" the way its comment says; it reads the first minute-form duration anywhere in the tail.
"TestChattyChild took 0.86s (package total 1m20s)"
-> [{Name:TestChattyChild Claimed:80 Recorded:[0.86]}]
That is a truthful sentence. TestChattyChild really did take 0.86s and the package really did take 1m20s, and the nudge now tells the model its answer said 80s about a test its answer said 0.86s about. Same failure class as the one just fixed: the tripwire cries wolf, and a tripwire that cries wolf gets turned off.
Picking whichever pattern matches earliest, rather than minute-first, fixes it. FindStringSubmatchIndex on both and prefer the minute form only when it starts no later than the seconds form. I checked that keeps the legitimate cases, including 1m10s (was 65s) where the minute form genuinely comes first.
Being precise about the reach, because I checked rather than assumed: of the three shapes I tried, only the parenthetical-total one reproduces through Conflicts. A table row and a two-clause sentence both came back clean, so this is narrower than it first looks. It is still the most natural way anyone writes a per-test timing next to a package total.
TestAMinuteDurationIsReadWhole only exercises minute-first tails, which is why the suite is green. A case with an s/ms figure ahead of a minute figure is what would have caught it.
Scope, unchanged from last time
Nothing imports internal/measurements yet, so none of this is firing in the product. Same reason I am raising it now rather than after the orchestration work adopts it.
…shaped one Raised by @Vasanthdev2004 against the minute support added in the previous commit. Trying the minute pattern over the whole tail before the seconds pattern let it reach past a nearer figure to claim a later one: "TestChattyChild took 0.86s (package total 1m20s)" -> [{Name:TestChattyChild Claimed:80 Recorded:[0.86]}] The claim is the test's own 0.86s; the 1m20s is the package total that `go test` prints after it. Reading the far number as the claim invents a conflict against a number the model got RIGHT, then quotes it back as a correction — the one failure this package exists to avoid, and worse than the miss it was fixing, because a missed conflict is silence while this is a confident wrong accusation. Both patterns are now located with FindStringSubmatchIndex and position decides: the minute form wins only when it starts no later than the seconds form. Group 2 is optional, so a bare "1m" reports index -1 rather than an empty span, which is why the check is `>= 0` and not a string test. Every case in TestAMinuteDurationIsReadWhole put the minute figure first, so it passed against this. The new test fails without the fix on both a trailing package total and a trailing budget ("450ms, well under the 2m budget" -> 120), and still catches a fabricated 5m00s when a seconds figure sits nearby.

Re-reviewed at 66fcdca3. The minute-ordering problem is closed, and I checked the three shapes that produced it plus the two that had to keep working:
"TestChattyChild took 0.86s (package total 1m20s)" -> []
"| TestChattyChild | 0.86s | 1m20s total |" -> []
"TestChattyChild took 0.86s, TestSlow took 1m20s." -> []
"TestSlow took 1m10s." -> []
"TestSlow took 1m10s (was 65s)" -> []
The earlier prefix collision stays closed at the same time, both for a subtest against its parent and for internal/agentinit against a recorded internal/agent, and a genuinely fabricated claim is still caught. That last check is the one worth keeping, since every fix in this package moves in the direction of accusing less.
Also good: the follow-up test now asserts the parent's own duration rather than only the subtest's, which was the vacuous half I mentioned but did not block on.
Approving. This package is going to be load-bearing for whether a report can be trusted, and it now behaves like something that has been argued with.

The latest parent-fixture, prefix-boundary, minute-duration, and nearest-duration fixes are correct. Three correctness issues remain:
-
[P1] Bound each parsed duration to its own measurement clause.
claimedSecondsForscans the entire remainder of a line after a matched name. I recordedTestFoo=0.10sandTestBar=4.20s, then checked the truthful lineTestFoo passed; TestBar took 4.20s; it produced a fabricated conflict forTestFooby borrowingTestBar's duration. -
[P1] Preserve run provenance/variant.
Recordaccepts only output text and pools values inmap[name][]seconds, losing command, arguments, cwd, and variants such as ordinary versus-race. A claim labelled as the normal run can silently borrow a race-run value because matching any pooled value is accepted. -
[P2] Do not permanently disable validation after one warning.
raised[name]suppresses every later contradiction for that name. RecordingTestFoo=0.10s, checking4.20s, then checking the distinct bad correction9.90sreports only the first conflict. Dedupe the specific warning/value, or bound retries at the caller.
The package tests pass under the race detector on 66fcdca.
…d its own value All three from @anandh8x, all reproduced before changing anything. The package has no callers yet, so the data model could be fixed rather than worked around. A DURATION BELONGS TO THE NAME BESIDE IT. claimedSecondsFor searched the whole remainder of the line, so one name took another's number: recorded: TestFoo 0.10s, TestBar 4.20s claim: "TestFoo passed; TestBar took 4.20s" -> [{Name:TestFoo Claimed:4.2 Recorded:[0.1]}] Every word of that claim is true. This is the same failure as reading a package total as a test's own timing, reached through the name binding instead of the pattern order — and it is the one this package must never produce, because a missed conflict is silence while this is a confident wrong accusation. The clause now ends where the next recorded name begins; the ledger knows those names, so they are passed in rather than guessed at from punctuation. TIMINGS FROM DIFFERENT COMMANDS ARE DIFFERENT MEASUREMENTS. Everything pooled into map[name][]seconds, losing which command produced what, so a claim about an ordinary run was satisfied by a value only `go test -race` ever printed — and -race is routinely several times slower, which is the size of discrepancy this exists to catch. Record and Conflicts now take the Run, and the ledger is keyed by run FIRST so a future caller cannot reintroduce the pooling by forgetting to pass it. A zero Run is still a legitimate "this caller does not distinguish runs", but the call site now says so out loud instead of it being the only thing the type could express. The nudge names the command, so the model is told which run to repeat. A SECOND WRONG NUMBER IS A SECOND THING TO SAY. Suppression keyed on the name alone switched the check off for that test permanently: after one bad 4.20s, a later and differently bad 9.90s was silent. It keys on the claimed value too, so re-reading the SAME answer still says nothing — which is all the dedupe was for, and what keeps a correction fed back to the model from looping. Each mutation-checked: unbinding the clause, pooling the runs, and suppressing by name alone each fail the test that covers them.

Reviewed at e589153d. The package has roughly tripled since I approved 66fcdca3, so this is a fresh look rather than a re-check, and the three earlier defects are all still closed.
One blocker in the new clause-bounding layer.
A full stop does not end a clause, so the next sentence's number is charged to the previous sentence's test
clauseSeparators is {";", ",", " and ", " but ", " while ", " whereas ", " though "}. No sentence terminator. When the following sentence's subject is an ordinary noun phrase rather than a name the ledger knows or something name-shaped, nothing bounds the clause and the second sentence's duration is read as the first sentence's claim:
"TestNested is green. The full run took 34.249s."
-> [{Name:TestNested Claimed:34.249 Recorded:[0.03]}]
"TestChattyChild passed. Total wall time 34.249s."
-> [{Name:TestChattyChild Claimed:34.249 Recorded:[0.86]}]
Both sentences are true. Both numbers were really measured, and the writer attached each to the right subject. The report is accused of fabricating a number it reported correctly, which is the failure your own package doc says gets the tripwire turned off.
Scope, measured rather than assumed, because it is narrower than it first looks:
- Only when the first sentence carries no duration of its own.
"TestNested passed in 0.03s. The full run took 34.249s."is clean, because the first duration in the clause wins. - Only within one line. A newline bounds it.
- Not every shape leaks. A colon did not, and neither did
"TestChattyChild ok. Package total 34.249s."So there is something else bounding some of these, and I did not chase which.
The bounds that do exist work, which is worth saying since it localises the fix. All of these stay silent:
"TestNested is green, and the full run took 34.249s." (separator)
"TestNested is green. github.com/Gitlawb/zero/internal/cli took 34.249s." (recorded name)
"TestNested passed in 0.03s. The full run took 34.249s." (first duration)
And a genuine fabrication is still caught. Adding sentence terminators to the separator list looks like the whole fix, and per your own comment every bound can only shorten the search, so it can cost a detection but cannot invent one.
Not verified, passing on as a lead
The review also flagged that ConflictsAcrossRuns merges every run's values for a name but names only one command in the nudge, so the sentence attributes the union to a single run. I did not stand that one up myself. Worth a look since it is the new cross-run entry point.
Still closed
The prefix collision, the 1m10s parse, and the minute-beats-earlier-seconds ordering are all fine at this head, and a fabricated claim is still caught. Four rounds in, nothing that was fixed has come back.
…es no single command Both reproduced before changing anything. A FULL STOP ENDS A CLAUSE. @Vasanthdev2004's blocker. clauseSeparators had no sentence terminator, so when the next sentence's subject was an ordinary noun phrase — not a recorded name, not name-shaped — nothing bounded the clause and its number was charged to the previous sentence's test: "TestNested is green. The full run took 34.249s." -> [{Name:TestNested Claimed:34.249 Recorded:[0.03]}] Both sentences are true, both numbers were really measured, and the writer attached each to the right subject. Accusing a correct report is the failure this package's own doc says gets the tripwire switched off. A decimal point is not a terminator and neither is the dot in an import path: a terminator is followed by whitespace or the end of the line and never sits between two digits. A colon is now a separator too. One correction to the review, since it changes the scope rather than the fix: he reported "TestChattyChild ok. Package total 34.249s." as NOT leaking, and it does leak at this head — I measured it. The bound covers it either way, but the shape was not as narrow as it looked. A MERGED RESULT NAMES NO SINGLE COMMAND. @anandh8x's P1. ConflictsAcrossRuns merges every run's values for a name, and labelling that union with one run said that command reported a number it never printed: `go test ./a` in this session reported 0.1s, 0.2s where 0.2s came only from ./b. Choosing the run deterministically fixed the reshuffling and left the attribution just as untrue. With more than one run behind the values the label is dropped and the nudge names the session; with one run it is kept, which is the useful case because the model is told exactly what to re-run. Both mutation-checked: removing the terminator bound brings back three bleeds, and removing the attribution guard brings back two false attributions.

@Vasanthdev2004 @anandh8x — head The full stop. One correction, because it widens the scope rather than the fix. You reported The merged attribution — @anandh8x, you were right that deterministic selection removed the reshuffling without making the attribution true. With more than one run behind the values the label is now dropped and the nudge names the session; with one run it is kept, which is the useful case since the model is told exactly what to re-run. Two rounds ago I told you Mutation-checked: removing the terminator bound brings back three bleeds, removing the attribution guard brings back two false attributions. |

Reviewed at 36c79cdf. The clause-bleed class is closed. One separator is still missing, and it is the last thing I have.
The full stop fix works, and so does everything around it:
ok "TestNested is green. The full run took 34.249s."
ok "TestChattyChild passed. Total wall time 34.249s."
ok "TestNested passed. Everything else finished inside 34.249s."
control "TestNested is green, and the full run took 34.249s."
control "TestNested passed in 0.03s. The full run took 34.249s."
caught "TestNested took 9.99s."
caught "TestChattyChild took 12.00s."
Honest reports cleared, controls silent, fabrications still caught.
The ASCII hyphen still leaks
I walked nine separator shapes to find out whether this was a class or an instance. It is an instance:
ok "TestChattyChild passed. the suite took 34.249s."
ok "TestChattyChild passed; the suite took 34.249s."
ok "TestChattyChild passed: the suite took 34.249s."
ok "TestChattyChild passed, the suite took 34.249s."
ACCUSED "TestChattyChild passed - the suite took 34.249s."
ok "TestChattyChild passed — the suite took 34.249s."
ok "TestChattyChild passed – the suite took 34.249s."
ok "TestChattyChild passed (the suite took 34.249s)"
ok "TestChattyChild passed | suite 34.249s"
Eight of nine bound correctly. The em dash and en dash are both fine, which is what makes the plain hyphen worth fixing rather than shrugging at: it is the one everyone actually types.
I want to be consistent about this, because on #912 I told you not to grow a list per counterexample and I am now asking you to add a list entry. The difference is that clause punctuation is a closed set you can enumerate and be done with, while the ways a person can admit defeat in English are not. clauseSeparators already has the semicolon, the colon and the comma. The hyphen belongs beside them, and after that the set is finished.
Nothing else outstanding. The prefix collision, the 1m10s parse, the minute-ordering and the full-stop bleed are all closed, and the merged-result naming from the last round appears to have been picked up in the same commit.
…follows it @Vasanthdev2004 found the ASCII hyphen still leaking. Walking the same nine shapes here found FIVE that leak, not one — the finding is a class, not an instance: ACCUSED "TestChattyChild passed - the suite took 34.249s." ACCUSED "TestChattyChild passed — the suite took 34.249s." ACCUSED "TestChattyChild passed – the suite took 34.249s." ACCUSED "TestChattyChild passed (the suite took 34.249s)" ACCUSED "TestChattyChild passed | suite 34.249s" The review reported the em dash, en dash, parenthetical and pipe as bounding correctly. They do not at 36c79cd; each is quoted above from a run against that head. This does not change his recommendation, only its size: clause punctuation is still a closed set, and it is now enumerated. PUNCTUATION ALONE IS NOT THE BOUNDARY. Adding the missing separators outright cost real detections, because the same marks are how a test's OWN number gets written: "TestChattyChild (9.99s)" "TestChattyChild passed - 9.99s" What makes a mark a break is a SUBJECT named after it, so the test is whether any word appears between the separator and the next duration. That rule also recovers two detections the pre-existing comma and colon separators were already costing silently — "TestChattyChild passed, 9.99s" and "…passed: 9.99s" were both MISSED at 36c79cd and are caught now. Measured on the widened set: 11 bleed shapes bound, 10 own-number shapes read, none lost. Mutation-checked both halves — removing the new separators leaks 7 shapes, and removing the subject rule loses 8 detections. Reviewed adversarially before committing: hyphenated test names and import paths still parse, the minute and millisecond forms are read after a separator and bounded before one, and a truncated "(" or trailing "-" is inert.

Reviewed latest head 7bdb761. The remaining ASCII-hyphen clause bleed is fixed, along with sentence terminators, unrecorded neighboring names, cross-run deduplication, and merged-run attribution. Punctuation carrying the test's own duration remains readable, while following-subject durations no longer bleed backward. The package passes under the race detector and git diff --check is clean.
The package is intentionally not wired into callers in this independent split, as disclosed. I found no remaining correctness or architectural blocker. Good to merge after the normal CI requirements.

@Vasanthdev2004 — head Your finding was right, and larger than reported. Walking the same nine shapes here found five leaking, not one: You had the em dash, en dash, parenthetical and pipe down as bounding correctly. They do not at Adding them outright cost real detections, which is what took the extra step. The same marks are how a test's OWN number gets written — That rule also recovers two detections the comma and colon were already costing silently: 11 bleed shapes bound, 10 own-number shapes read, none lost. Mutation-checked both halves. I ran the review pass before committing this time; it flagged two cases that turned out to be my own badly-built fixtures — I had made the claim agree with the record — and re-testing with disagreeing values showed hyphenated names, import paths, and the minute and millisecond forms all behaving. |

…disarmed CodeRabbit's findings on the current head, all verified before changing anything. HOURS COUNT, for the reason minutes did one round earlier. Without an hour form "1h10m0s" matched only its minute remainder and read as 600s, so a truthful restatement of a recorded 4200s was reported as a fabrication — the accusation this package exists to avoid, one unit further up. The hour form is its OWN pattern rather than an optional prefix on the minute one. Making every part optional lets the expression match the EMPTY string, which regexp then finds at offset 0 ahead of any real duration: that version read "1h10m0s" as 0s, which is worse than the bug it was fixing. I shipped it that way for one iteration and the round-trip table caught it. A TEST THIS PR HAD DISARMED. The stability assertion recorded the SAME name under both runs, which makes the report a merged one — and the merged-attribution fix earlier in this same PR drops the label for merged reports. So it watched an always-empty string and could not have failed. A production change silently disabled a test guarding a different property, which is the fourth time in this series that a green test was asserting nothing. It now uses one name per run, so a single run stands behind the conflict and a label exists to be stable, and it fails outright if the label is ever empty again. Also from the review: ConflictsAcrossRuns is asserted nil-safe alongside the other two entry points, the dedupe doc now says name AND VALUE rather than name alone, and the unused outer ledger is gone from the honest-reporting table. The plain-seconds fall-through now checks for nil rather than relying on the branch conditions above it to guarantee non-nil. That was provably safe and provable-by-argument is what this file has already paid for once. Mutation-checked: disabling the hour branch reports 1h10m0s as 600s and 1h2m3s as 123s, and recording one name under both runs fails the stability test outright.

420-446: 📐 Maintainability & Code Quality | 🟡 Minor | ⚡ Quick winThis loop pins label stability, not the "lowest run key wins" rule.
TestOnlyPlainis recorded by one run, somergedhas exactly one candidate run for that name. The selection is unique before the sort at measurements.go Lines 684-688 does anything, and the label is stable for that reason alone.The sort matters only when two runs recorded the same name. In that case
seen.runs > 1setsattributed = Run{}(measurements.go Lines 736-739), so the chosen run never reaches the caller. So the rule the comment at measurements.go Lines 678-683 describes — the lowest run key wins, to stop the nudge naming a different command between passes — is unobservable through the exported API, because attribution-dropping already prevents that outcome.The sort is still worth keeping as defence against a future change to the attribution rule. Update the comment at measurements.go Lines 678-683 so it does not claim to fix a user-visible instability that a different rule prevents, and keep this loop's stated purpose to what it checks: a single-run conflict keeps its label.

Two CI checks fail on this package, and the guidelines treat them as hard requirements.
Smoke (windows-latest) and Security & code health both report unreachable func for ParseGoTest (Line 120), Run.Label (Line 80) and Run.key (Line 74). The cause is the deliberate absence of importers stated in the PR description: no entry point reaches the package, so every exported symbol reads as dead, including Run.key and Run.Label, which the package itself calls.
The PR description reports formatting, vetting, building, tests and race checks clean, but not these two checks. Resolve one of these before merge:
- add the
internal/agentorinternal/specialistcall site in this PR, which removes the finding at its root; or - record the exact failing check output in the PR description and obtain maintainer direction on an exclusion.
As per coding guidelines, "Formatting, vet, tests, build, smoke, diff hygiene, and vulnerability checks are hard requirements; report exact environment or unrelated external failures and obtain maintainer direction rather than silently ignoring them."

Reviewed at db58dbf6. The hyphen is closed and so is everything around it. Six separator shapes, all clean, and a fabrication still caught:
ok "TestChattyChild passed. the suite took 34.249s."
ok "TestChattyChild passed; the suite took 34.249s."
ok "TestChattyChild passed: the suite took 34.249s."
ok "TestChattyChild passed, the suite took 34.249s."
ok "TestChattyChild passed - the suite took 34.249s."
ok "TestChattyChild passed (the suite took 34.249s)"
Approving.
Worth noting what you did in the same commit without being asked: re-arming a test this PR had disarmed. That is the failure mode I have spent most of this week finding in other people's branches, and catching it in your own is harder than catching it in someone else's.
Five rounds, and every round closed what it was asked to close. The prefix collision, the 1m10s parse, the minute-beats-seconds ordering, the full-stop clause bleed and the hyphen are all shut, and the honest-report side never regressed once while that was happening. That last part is the one that mattered: this package accusing a truthful report is how it gets turned off.
…ge parses
CodeRabbit's finding on the current head, verified before changing anything.
separatorBreaksClause locates the next duration to decide whether a separator
introduces a new subject, and it knew the seconds and minute patterns but not the
hour one added a commit earlier. So it read the "h" of "9h" as the first letter
of a new subject, turned the punctuation into a clause boundary, and cut the
test's own number away from its name:
"TestVerySlow - 9h" missed
"TestVerySlow passed - 9h" missed
"TestVerySlow (9h)" missed
"TestVerySlow: 9h" missed
"TestVerySlow took 9h" caught, because no separator was involved
A duration this package can PARSE has to be one this scan can SEE, or the two
disagree about where a clause ends — and the disagreement is silent, because the
answer it produces is the same shape as an honest bound.
Both bounds still hold: an hour figure belonging to another subject
("…passed - the whole suite took 9h") stays that subject's, and a truthful
1h10m0s restatement of a recorded 4200s is not a conflict.
NOT DONE, with the reason. The review also asked for a real ParseGoTest call site
from internal/agent or internal/specialist to clear an unreachable-function
finding. ParseGoTest is called by Record at measurements.go:213, and the
integration that calls Record lives in Gitlawb#829 — this split branch deliberately has
no caller, which is the same for Run.key and Run.Label. Adding one here to quiet
a reachability scan would put the wiring in the wrong PR.
Mutation-checked: dropping the hour pattern from the scan misses all four
separator spellings again.

Reviewed at 7acb3661. Eleven honest report shapes, none accused; three fabrications, all caught.
That covers everything raised across six rounds in one pass: the prefix collision on both a subtest and a package path, the 1m10s parse, the minute-beats-earlier-seconds ordering, the full-stop clause bleed, the ASCII hyphen, and the leading-duration case. Plus the six separator forms.
Approving. No live review from anyone else on this head; I checked before posting.
Six rounds is a lot, and worth saying why it was not wasted: every round here closed something real and none of it was churn. The thing that makes this package worth the trouble is the asymmetry it is built on, that a false accusation is more expensive than a missed one, and the honest-report side never regressed once while the detection side kept tightening.

@anandh8x — head Since your review: the cross-run attribution no longer names one command for a merged result, the clause bound gained the sentence terminator and the punctuation class, the hour form is read whole, and the clause scan now sees every duration the parser can parse. Each is mutation-checked. |

Reviewed latest head 7acb366. Hour and compound durations are parsed whole, the clause scan recognizes every supported duration form, and all earlier prefix, punctuation, sentence-boundary, cross-run attribution, provenance, and deduplication findings remain closed. Honest-report and fabrication controls pass, and the package is clean under the race detector. The zero-value Ledger concern is nonblocking because this package documents and exposes NewLedger, and no caller currently bypasses it. Good to merge after normal CI requirements.

Split out of #829 — independent package
Fourth piece of the split @Vasanthdev2004 asked for. Not stacked on #891/#897 — it builds and tests against current
mainon its own.What it is for
A measured run finished a benchmark and reported a table of test timings that no command in the session had produced:
0.86sin one paste and4.20sin the next, with nothing said about the difference-raceoverhead moved from+3.7%to+133%between two tellings of the same resultWhy a prompt rule is not the fix
"Re-run every command before you paste it" is the obvious answer and the weak one: a model willing to write numbers it did not measure is equally willing to say it re-ran them. The check has to live somewhere the model cannot assert its way past.
The harness qualifies. Every command's output passed through this process and was written to the session log, so the run's real numbers are already there — this package reads them back and compares them against what the answer claims.
Deliberately loose
Timings vary for honest reasons: a loaded machine, a warm cache, a different
-count. The tolerance is a 50% band, which lets ordinary variation through and still catches0.86sreported as4.20s.That asymmetry is on purpose. A tripwire that cries wolf gets turned off, and then it catches nothing; a false negative costs one uncaught number. So it errs firmly toward silence.
Note on importers
None in this PR, by design —
