Let the review finish, and make it read what it is reviewing by fatihacet · Pull Request #106 · kaicontext/kai-cli

fatihacet · 2026-09-10T14:32:09Z

Three changes to one failure, measured across 740 merged PRs in this org and 432 adjudicated findings on the 80 where Kai and a competitor both reported.

Of 89 real defects another reviewer found and Kai did not, 56 were visible in the changed lines themselves. The miss rate does not depend on how far the evidence sits from the diff:

evidence lives	n	Kai missed
in the diff	88	64%
another file, same repo	36	67%
behind a caller	6	67%

Distance is not the explanation. Not looking is.

1. The turn budget is the one that binds

MaxTurns has been a flat 20 since dc19c2a (2026-07-07) — set in a commit about diff patches, never revisited — while the time budget was raised twice on measurement (5m→9m soft, 12m→20m hard). The budget that was tuned is not the one that runs out.

Across 85 live reviews carrying the coverage manifest:

	median	p90	max	limit
wall clock	90s	319s	711s	540s soft
turns	10	18	20	20

Twenty turns at the observed 9.3s/turn costs about 187 seconds. The runner also injects wind-down hints three turns before the cap and strips every tool on the final turn, so a flat 20 is 17 turns of real work no matter how large the change.

It shows up exactly where you would predict:

changed files	n	opened	not opened	in wind-down	clock used
1	15	2.8	0.1	7%	14%
2–3	38	3.8	0.5	11%	28%
4–8	21	6.0	1.8	10%	26%
9+	11	6.5	8.4	45%	39%

Findings per changed file fall from 1.40 on a one-file PR to 0.14 on a PR of twenty-one or more.

The budget is now sized to the diff — 20 + 2 per changed file, capped at 45. Never below the old value, and the ceiling is chosen so the wall clock becomes the binding limit again: 45 turns at the measured pace is ~420s, inside the soft budget. Anything slower hits the time budget and degrades the way the time budget already handles. TestReviewMaxTurnsScalesWithTheChange asserts that ceiling against rcReviewSoftBudget so the two cannot drift apart.

2. A review that skipped a file is asked for it

The manifest could already tell a reader which changed files a review never opened. The only consequence was the disclosure.

Now the run is asked to go back: a second pass that resumes the same session (Options.SessionID), names the files, and asks for the whole review again with its coda. It keeps everything already read and pays only for what was skipped.

Bounded and non-destructive by construction:

skipped when the first run died on the clock — no point asking for more reading from a run that ran out of time;
capped at one turn per skipped file plus four, ceiling 16;
its answer is adopted only if it carries a coda, so a failed second pass leaves the first review exactly as it was.

kai-tui#108 is the specimen: "2 of the 4 changed files don't appear below: do_budget.go, do_budget_test.go" — and the defect a competitor found on that PR was in do_budget.go.

3. The reviewer is told about one commit of twelve

rcAuthorContext used the branch's commits only when the reviewed ref was a merge. CI reviews $HEAD_SHA --base $BASE_REF, and a PR head is an ordinary commit, so isMerge was false on every review a customer ever got. rcRangeCommits collected the range one line above the call and this function discarded it, handing the reviewer the last commit's message as the author's account of the whole change.

It now uses the range whenever there is more than one commit in it. A merge still reads as a merge; a single commit still states itself.

TestAuthorContextUsesEveryCommitOnANonMergeHead fails on the parent commit, and the failure shows the bug directly:

author context for a multi-commit branch is missing "the migration rekeys daily_usage":
    console: show the pooled balance

    and the 429 body loses its dollars

4. And the manifest counts turns

rcIncomplete.Turns was len(res.Transcript) — the message count, roughly twice the turns — so a review that ran 19 turns published "38 turns". A manifest that exists to stop overclaiming cannot overclaim by 2×.

Release note

This reaches production through the digest-pinned kai-ci image, so it needs a kai-cli tag and an image build after merge. Pairs with kaicontext/kai-engine#96, which grants kai_context to ModeReview — the prompt has been ordering that tool since the grounded reviewer shipped and the mode filter has been deleting it.

Summary by CodeRabbit

New Features
- Review effort now scales with the number of changed files, within a safe limit.
- Reviews verify that all changed files were examined and request a complete follow-up review when coverage is incomplete.
- Multi-commit reviews now include the full author context, including each commit’s subject and body.
Tests
- Added coverage for review budgeting, file coverage checks, turn counting, and multi-commit author context.

Kai review

Kai Summary

Read through this one. 3 things worth your eyes before it merges. 👇

Review of kaicontext/kai-cli @ 01153f1 — review-commit turn budget, coverage gate, multi-commit author context, turn counting

The rest of the read-through

I read the diff in cmd/kai/review_commit.go, cmd/kai/review_commit_ground.go, and both test files, plus the call sites of rcAuthorContext, rcRunReviewAgent, rcFilesRead, and the agent.Run session-resume pattern in internal/tui/views/planner_dispatch.go. I could not read github.com/kaicontext/kai-engine/{agent,message} source directly — it is a versioned module dependency (v0.6.67), not vendored in this repo — so the resume semantics (agent.Options.SessionID and the scope of res.Transcript on a resumed run) are grounded only from how this repo already uses them, not from the engine's own code.

The change does four things, all aimed at making the reviewer actually read what it reviews: sizes the turn budget to the diff (20 + 2/file, cap 45), adds a second-pass "coverage gate" that resumes the session to ask about changed files the first pass never opened, feeds the reviewer every commit in the branch range rather than just the head, and counts assistant turns instead of raw message count. The intent framing and the deterministic pieces (turn-budget math, rcDiffPaths, rcUnopenedChanged, rcAuthorContext, rcTurns) are sound and well-tested. The coverage gate's accounting, however, reintroduces the very 2× overcount this change sets out to fix.

inc.Turns += rcTurns(res2.Transcript) double-counts the first pass on a resumed session — cmd/kai/review_commit.go:862. The gate resumes the first run's session (gate.SessionID = res.SessionID, line 854). This repo already documents, in internal/tui/views/planner_dispatch.go:2419-2426, that "on a resumed session Transcript is the whole conversation" — and that the prior turn's assistant messages are present in it (that comment exists to warn about replaying the prior turn's answer). So res2.Transcript on the resumed gate run contains the first pass's assistant turns plus the second pass's. Line 826 already set inc.Turns = rcTurns(res.Transcript) (the first pass's turns); line 862 then adds rcTurns(res2.Transcript), which includes those same first-pass turns again. The coverage manifest publishes inc.Turns, and this change's own stated purpose is that the manifest "cannot overclaim by 2x" — yet on any review where the gate fires, inc.Turns ends up roughly (first turns) + (first turns + gate turns), the first pass counted twice. The author even had this exact hazard in view: the planner comment at 2419-2426 says to use res.FinalText (scoped to this run) rather than walking Transcript for the last assistant message, precisely because the transcript carries the whole history on a resume. The same scoping applies to turn counting. Fix: count only the new assistant turns — subtract rcTurns(res.Transcript) before adding, or use a per-run turn count if the engine exposes one. As written, no test catches this: TestTurnsCountsTurnsNotMessages exercises rcTurns on a synthetic flat transcript, and TestCoverageGateTurnsStayBounded exercises the turn budget, but nothing drives the gate's inc.Turns += accumulation against a resumed-session-shaped transcript (first-pass messages followed by gate messages), which is the one place the overcount lives.

The gate's opts copy inherits the first run's soft budget and runs under its already-spent hard deadline — cmd/kai/review_commit.go:853. gate := opts copies SoftTimeBudget/SoftTimeBudgetExtension (lines 801-802) and runs under the same ctx whose rcReviewHardDeadline (20m, line 769) has been ticking since started. The comment at line 844 says the gate is skipped "when the first run died on the clock," and the only such check is res.FinishReason != message.FinishReasonTimeBudget (line 850). A first pass that ran 18 of its 20 hard-deadline minutes but finished with FinishReasonEndTurn (it used its turns, not the clock) passes that guard, and the gate then runs against about 2 minutes of remaining hard deadline with its own rcCoverageGateTurns budget on top. The gate is bounded (cap 16 turns), so it degrades rather than hangs — but a slow-provider run could make the second agent.Run hit the hard deadline and return FinishReasonTimeBudget, which line 864 then writes into inc.FinishReason, turning a first pass that did finish cleanly into a manifest that reports "ran out of time." I could not confirm whether the engine's soft-budget extension fires per-run or cumulatively on a resume (that is in kai-engine, which I cannot read), so this is: within this repo, the gate inherits a context and a soft budget whose remaining headroom is unverified. A hard-deadline check before starting the gate, or a fresh context like rcConcludeFromTranscript uses, would close it.

rcDiffPaths keys on +++ b/ — confirm rcCommitDiff emits that format — cmd/kai/review_commit.go:892. rcDiffPaths parses only lines prefixed +++ b/. The diff fed to rcRunReviewAgent comes from rcCommitDiff(reviewCommitBase, ref, ...) (line 294). If that helper ever emits a diff format without the +++ b/ prefix, rcDiffPaths returns an empty list, rcReviewMaxTurns(0) gives the base 20 (fine — never below the old value), but rcUnopenedChanged([], …) returns nil (line 918 short-circuits on len(changed) == 0), so the gate never fires even when files were skipped. That is a silent loss of the gate, not a wrong verdict. I did not read rcCommitDiff to confirm it emits unified +++ b/ headers; TestDiffPathsListsWhatTheChangeTouches only proves the parser works on a hand-written unified diff, not that the real diff matches it. A one-line check that rcCommitDiff output starts with diff --git/+++ b/ would close this.

The turn-budget scaling, rcAuthorContext multi-commit fix, and rcTurns are correct and the tests genuinely exercise them. The ceiling-vs-soft-budget assertion at budget_test.go:30 would fail if the cap were raised past 540s/9.3 — a good guard. TestAuthorContextUsesEveryCommitOnANonMergeHead asserts all three subjects and a body appear and would fail on the parent (which returned only subs[2]+bodies[2]), so that fix is real. rcCoverageGatePrompt correctly asks for the whole review again with the coda, and the gate adopts the second answer only if it carries rcReviewDataMarker — a failed second pass leaves the first review intact, as claimed. rcUnopenedChanged's suffix match is asymmetric (the HasSuffix(c, "/"+r) arm is narrower than the comment implies), but the cheap-side error — asking for a file that was read — is harmless, as the docstring concedes.

One decision worth a human's eyes before this ships as the default for every review: the 45-turn ceiling and the 16-turn gate cap are tuned to a measured 9.3s/turn pace and a 540s soft budget drawn from the author's own live-review sample, which I cannot see and could not re-verify. Those numbers govern how long every customer's grounded review runs and, via the gate, how much extra model spend a multi-file review incurs. The math is internally consistent (45 × 9.3 ≈ 419s < 540s), but the binding limits rest on that sample. If the pace drifts — a slower model tier, a heavier graph — the ceiling stops being inside the soft budget and the wall clock binds earlier than intended. Confirm the 9.3s/turn figure is current across the model tiers customers actually use before this becomes the default.

This needs work before it merges: the coverage gate is the headline feature of this change, and its turn accounting reintroduces the overcount the change exists to fix. The other two items are local and quick to confirm.

inc.Turns += rcTurns(res2.Transcript) counts the first pass's assistant turns a second time, because a resumed session's transcript holds the whole conversation (per planner_dispatch.go:2419-2426); fix by counting only new turns.

the gate's gate := opts copy runs under the first run's already-spent 20m hard deadline and copies its soft budget; a first pass that used its turns but ended cleanly can leave the gate too little clock, and a gate that times out overwrites inc.FinishReason with TimeBudget.

Confidence Score: 2/5

The PR is not yet safe to merge because rename coverage and both incomplete-response paths can still leave changed files or discovered findings out of the published review.

Findings

Rename paths remain unopenable ▶
Partial codas discard findings ▶

Fix with agent prompt

### Issue 1
cmd/kai/review_commit.go:1038-1043
When Git reports a detected rename, `rcPathsOf` retains the numstat expression such as `old => new` instead of the destination path. No file read can match that value, so the coverage pass requests a nonexistent path and never tracks the renamed destination as reviewed.

### Issue 2
cmd/kai/review_commit.go:1171-1178
When the bounded coverage pass stops after emitting `INTENT_MATCH` or `SUMMARY` but before `ISSUES`, `rcUsableCoda` accepts that response and replaces the complete first-pass review. Transcript recovery is then skipped, so the parser publishes an empty-risks review and discards the first-pass findings.

For each issue above, determine whether it is valid and should be fixed. If so, fix it directly.

Normalize manifest paths before comparing them.

This suffix match treats internal/foo.go as evidence that the agent opened changed file foo.go. When both paths exist, the coverage gate skips the unread changed file.

Normalize absolute paths relative to primary.Path, then compare normalized repository-relative paths exactly.

Enumerate all unopened paths in the coverage gate or repeat the gate for the remaining paths. When rcUnopenedChanged finds more than 12 files, rcCoverageGatePrompt names only the first 12 and replaces the rest with a count. rcRunReviewAgent invokes this gate once, and a non-empty still list only produces a log message. The omitted files therefore lack explicit coverage targets, and rcCoverageGateTurns also caps the pass at 16 turns.

Six findings from Kai, CodeRabbit and Greptile on this branch. Five were real and are fixed here; the sixth was a decision and is answered in code. ## The gate double-counted the first pass (Kai) `inc.Turns += rcTurns(res2.Transcript)` added the resumed run's turns to the first run's — but a resumed session's Transcript is the WHOLE conversation (runner.go seeds history from session.History()), so the first pass was counted twice. That republished the exact 2x manifest overcount this change removes. Assignment, not addition, and the same for FilesRead. ## Changed-file discovery read the truncated diff (CodeRabbit, Greptile) rcDiffPaths scanned `+++ b/` headers in the PROMPT's diff. That text is truncated at 120KB, a deletion's hunk ends at `+++ /dev/null`, and a binary or mode-only change has no `+++` header at all — so the list that sizes the turn budget and drives the coverage gate silently omitted files on exactly the large changes both exist for. Paths now come from rcCommitDiffStat, which asks git. That is also the list the server compares the manifest against (changedFilesNotListed reads the bundle's diff.files), so the gate asks for precisely the files the review would otherwise be shown to have skipped. ## The gate ran on a deadline that was already spent (Kai) `gate := opts` inherited SoftTimeBudget and ran under the first pass's ctx, whose 20-minute hard deadline had been ticking since the run started. A first pass that spent its turns but finished cleanly could hand the gate seconds — and a gate that then died on that inherited deadline wrote FinishReasonTimeBudget over a first pass that had finished perfectly well. The gate now gets its own bounded context and budget (rcGateHeadroom: what remains, capped at 4 minutes, zero below 45 seconds), and only adopts its FinishReason when its answer is adopted. ## A half-written second pass could replace a whole first one (CodeRabbit) The adopt condition was `strings.Contains(second, rcReviewDataMarker)`. A pass that ran out of turns mid-write emits the marker and stops, so that swapped a complete review for an incomplete finding. rcUsableCoda requires the marker AND a field behind it, and the conclusion fallback uses the same test. ## A discarded gate answer lost the files it had read (Greptile) When the gate opened the skipped files and then failed to write a usable coda, its answer was dropped AND the conclusion fallback was handed res.Transcript — the FIRST pass's history. Everything the gate read was thrown away. The fallback now gets the gate's transcript, which on a resumed session is a superset. ## The decision: 9.3s/turn (Kai) The ceiling is only correct while the measured pace holds, and the pace came from a sample. It is now rcObservedSecondsPerTurn, a named constant the ceiling test multiplies — so a slower model tier fails the test with a message naming the figure to re-measure, instead of quietly moving the binding limit. ## Also KAI_PR_TITLE / KAI_PR_BODY are now read into AUTHOR CONTEXT, closing the loop with kai-server#238: the description leads and the commits follow, so truncation drops supporting detail rather than the claim being tested. Absent variables leave the author context exactly as it is today.

Six findings across the three reviews. Five were real and are fixed in 7e42a44; the sixth was a decision and is answered in code.

#	Reviewer	Finding	Fix
1	Kai	`inc.Turns +=` double-counts the first pass on a resumed session	assignment, not addition
2	CodeRabbit, Greptile	changed-file discovery reads the truncated diff	paths come from `rcCommitDiffStat`
3	Kai	the gate runs on an already-spent deadline	its own bounded context + budget
4	CodeRabbit	a half-written second pass replaces a whole first one	`rcUsableCoda` requires a field, not just the marker
5	Greptile	a discarded gate answer loses the files it read	fallback gets the gate's transcript
6	Kai	the 9.3s/turn figure is unverified	named constant the ceiling test multiplies

1 — the turn double-count. Correct, and it republished the exact 2× overcount this PR removes. Confirmed in the engine rather than taken on trust: runner.go seeds history from session.History() on resume, so res2.Transcript is the whole conversation. Now inc.Turns = rcTurns(res2.Transcript), and FilesRead the same.

2 — the truncated diff. This was the worst of the six, because it broke the feature precisely where it matters. rcDiffPaths scanned +++ b/ in the prompt's diff: truncated at 120KB, a deletion's hunk ends at +++ /dev/null, and a binary or mode-only change has no +++ header at all. So on a large PR the list that sizes the turn budget and drives the gate quietly omitted files.

rcDiffPaths is gone. Paths come from rcCommitDiffStat — and that is also the list the server compares the manifest against (changedFilesNotListed reads the bundle's diff.files), so the gate now asks for exactly the files the review would otherwise be shown to have skipped. The two can no longer disagree.

3 — the spent deadline. gate := opts inherited SoftTimeBudget and ran under the first pass's ctx, whose 20-minute hard deadline had been ticking since started. A first pass that spent its turns but finished cleanly passed the FinishReasonTimeBudget guard and could hand the gate seconds — and a gate that died on that inherited deadline wrote FinishReasonTimeBudget over a first pass that had finished fine. rcGateHeadroom gives it what remains, capped at 4 minutes, zero below 45 seconds; FinishReason is only adopted when the answer is.

4 — the half-written coda. rcUsableCoda requires the marker and an INTENT_MATCH: or SUMMARY: behind it. The conclusion fallback uses the same test, so the two cannot drift.

5 — the lost reading. The sharpest of the three, because it was silent: a gate that opened the skipped files and then ran out of turns had its answer dropped and the fallback was handed res.Transcript — the first pass's history. Everything the gate read went in the bin. The fallback now gets the gate's transcript.

6 — the decision. Right to hand it back rather than resolve it. The ceiling is only correct while the measured pace holds, and the pace came from one sample on z-ai/glm-5.2. It is now rcObservedSecondsPerTurn, which TestReviewMaxTurnsScalesWithTheChange multiplies by the ceiling — so a slower model tier fails the test with a message naming the figure to re-measure, rather than quietly moving the binding limit. Still a human's call whether 45 is the right number; it is no longer a number that can rot unnoticed.

Also in this push: KAI_PR_TITLE / KAI_PR_BODY are read into AUTHOR CONTEXT, closing the loop with kaicontext/kai-server#238. The description leads and the commits follow, so truncation drops supporting detail rather than the claim being tested. Absent variables leave the author context exactly as it is today.

One note on Kai's coverage manifest for its own review here: it reports vendor/github.com/kaicontext/kai-engine/agent among the files it opened, and this repo has no vendor/ directory — worth a look separately, since a manifest naming a path that does not exist is the same class of problem the manifest exists to solve.

Rename paths remain unopenable

When Git reports a detected rename, rcPathsOf retains the numstat expression such as old => new instead of the destination path. No file read can match that value, so the coverage pass requests a nonexistent path and never tracks the renamed destination as reviewed.

Kai review

Kai Summary

Read through this one. 2 things worth your eyes before it merges, plus 3 decisions to say yes to. 👇

Where I'd land: 3/5 — small fixes first.

Scope: kaicontext/kai-cli, revision 7e42a44. I read review_commit.go, review_commit_ground.go, and both test files around the changes. I could not read kai-engine's agent.Run / runner.go (sibling repo) to confirm the resumed-session transcript semantics, message.FinishReasonTimeBudget's value, or whether agent.Run leaves session/lock state on context-cancellation abort — I flag that as outside my reach where it matters.

The rest of the read-through

What this does and my take: The change makes the agentic reviewer scale its turn budget to the number of changed files (capped at 45 so wall-clock stays binding), discovers changed files from git diff --numstat instead of the truncated prompt text, and runs a "coverage gate" second pass that resumes the session to open changed files the first pass skipped — adopting the second answer only if it carries a complete coda. It also fixes a 2x turn overcount, feeds KAI_PR_TITLE/KAI_PR_BODY into the author context ahead of commit messages, and uses every branch commit in that context rather than only the last one. The architecture is sound, the five fixes are real, and the test coverage is genuine. I found one concrete bug in rcUnopenedChanged, one resource concern I could not fully verify against the unread sibling repo, and decisions worth flagging.

rcUnopenedChanged false-negatives when a read path is a suffix of a different changed path (cmd/kai/review_commit.go:1034)

The suffix fallback is:

if strings.HasSuffix(r, "/"+c) || strings.HasSuffix(c, "/"+r) {

The second arm, HasSuffix(c, "/"+r), declares a changed file c "opened" if r is a suffix of c. Consider two changed files — db/secrets.go and pkg/db/secrets.go — where the reviewer opened only db/secrets.go (so r = "db/secrets.go", c = "pkg/db/secrets.go"). Now HasSuffix(c, "/"+r) = HasSuffix("pkg/db/secrets.go", "/db/secrets.go") = true — the unopened pkg/db/secrets.go is declared opened and silently dropped from the gate. This matters because the gate's entire purpose is to name the skipped files, and this path omits one whenever two changed files share a tail and only the shallower one was read. The first arm already handles the correct direction (a read path that is a deeper version of a changed file). The second arm is unsound. The fix is to drop it: r == c || strings.HasSuffix(r, "/"+c) covers every case the first arm covers. The existing test TestUnopenedChangedNamesTheSkippedFiles only exercises the true-positive direction of the first arm and never constructs the collision case, so it passes on the buggy code — to catch this you'd need a test with two changed files sharing a tail where only the shallower one was read, asserting the deeper one still appears in the output.

The gate's gcancel() is not deferred — resource safety on panic/abort unverified (cmd/kai/review_commit.go:881-883)

gctx, gcancel := context.WithTimeout(context.Background(), left) is cancelled with gcancel() called unconditionally on the line after agent.Run returns. That is correct for normal returns. The window between Run and gcancel is a single line with no allocations, so a panic there is unlikely to leak. What I could not verify, because agent.Run lives in kai-engine (outside this repo), is whether agent.Run spawns background goroutines or acquires a session-store lock on the resumed SessionID that is released only on clean return — a context-cancellation abort could leave the session in a state that blocks a later kai run summary. I'm flagging it as unverified, not as a confirmed defect; confirm against the runner.

rcUsableCoda and the conclusion fallback: stale FinishReason in stderr is cosmetic (cmd/kai/review_commit.go:921-922)

The fallback condition prints res.FinishReason — the first pass's finish reason — even after the gate ran and, on the success path, set inc.FinishReason to the gate's. The inc struct (the manifest) is correct; only the stderr diagnostic shows the older value. Not a defect — noting it so the author knows the two can diverge on the gate-success path.

The 9.3 s/turn figure is an unverified external claim, guarded in one direction only (cmd/kai/review_commit.go:174)

rcObservedSecondsPerTurn = 9.3 is presented as "the median turn cost measured across 85 live reviews on 2026-09-09 (z-ai/glm-5.2, the model the CI workflow exports)." The ceiling test multiplies it and fails if the product exceeds the 540s soft budget, so correctness of the binding-limit property depends on this number being accurate for the model that actually runs in CI. I cannot confirm the measurement, the model tier, or that the CI workflow still exports z-ai/glm-5.2 — those live in kai-server / the CI config, outside this repo. The test guard is the right design, but it only guards against the figure being too large (ceiling past the soft budget); if the figure is too small, the ceiling silently lets turns outrun the clock. The author's framing ("the test will say so") covers the too-large direction only.

Tests: I checked whether the fixes fail on the old code. TestTurnsCountsTurnsNotMessages fails on the old len(res.Transcript) — real. TestUsableCodaNeedsMoreThanTheMarker fails on the old strings.Contains — real. TestGateHeadroomNeverOutlivesTheReview fails if the gate inherited ctx — real. TestAuthorContextUsesEveryCommitOnANonMergeHead fails on the old !isMerge short-circuit — real. TestChangedPathsComeFromTheDiffStat guards the new rcPathsOf path. The one test that does not catch the bug I found is TestUnopenedChangedNamesTheSkippedFiles: it never constructs the shared-tail collision, so the unsound second HasSuffix arm passes today.

Decisions

Correct as written, but somebody should say yes to these:

The turn budget rises from a flat 20 to up to 45 turns (scaled per changed file); this increases provider token and wall-clock spend on every large-PR CI review. The wall-clock binding limit is test-guarded in the too-large direction only.
KAI_PR_TITLE/KAI_PR_BODY now lead the author context on every review pod where the control plane injects them, changing what the reviewer judges the change against; absent variables leave the context unchanged.
rcAuthorContext now includes every branch commit (not only the last) on non-merge heads, which is every CI review; intermediate/wip commit messages now enter the author context.

rcUnopenedChanged's second arm strings.HasSuffix(c, "/"+r) falsely marks an unopened changed file as read when a shallower changed file with a shared tail was opened; the test does not cover this direction.

the gate's gcancel() is not deferred; whether agent.Run (in kai-engine, unread) leaves session/lock state on context-cancellation abort is unverified, so an aborted resumed session could leak — confirm against the runner.

Three more from Kai on 7e42a44. One is a real bug in the gate's own accounting, which is the worst place for one. ## rcUnopenedChanged let a file out through a shared tail The suffix match had two arms. The second — "the changed path ends in the read path" — is unsound. With `db/secrets.go` and `pkg/db/secrets.go` both changed and only the first opened, HasSuffix("pkg/db/secrets.go", "/db/secrets.go") is true, so the deeper file was declared opened and dropped from the gate. Silent, and not exotic in a repo with parallel package trees. The gate exists to name the skipped files; this dropped one. Only the sound direction remains: a read path that ENDS IN the changed path, which is what an absolute path from the run's mktemp checkout looks like. TestUnopenedChangedIsNotFooledByASharedTail constructs the collision and fails on the parent: rcUnopenedChanged = [], want [pkg/db/secrets.go] ## The gate's cancel is now deferred gcancel() ran on the line after agent.Run returned — correct on the ordinary path, and an open question on any other. The run has its own scope now, so the cancel fires on every exit. Whether the runner leaves a session lock or a goroutine behind on an abort is no longer a question this code has to answer. ## The conclusion fallback printed the wrong reason It branched on inc.FinishReason's condition but printed res.FinishReason — the FIRST pass's. After a successful gate the two differ, so the diagnostic explaining why the fallback fired named a reason it did not fire on. Both now read inc. ## And the 9.3s/turn figure, in writing Kai is right that the ceiling test guards one direction only, and that is deliberate: too large and the ceiling leaves the soft budget with nothing else to catch it, so it is asserted. Too small and turns cost more than the constant says, so the run reaches rcReviewSoftBudget before its turn cap — the soft budget fires and the incomplete path reports it. That direction already has a backstop, and it is the one the design wants: the wall clock binding rather than the turn count. Now said in the comment rather than left for the next reader to reconstruct.

fatihacet · 2026-09-10T15:09:05Z

Three more, fixed in 358e333. The first is a real bug, and in the worst possible place — the gate's own accounting.

rcUnopenedChanged let a file out through a shared tail. Correct, and the reasoning is exactly right. The second suffix arm declared pkg/db/secrets.go opened because db/secrets.go had been. The gate exists to name the skipped files and this silently dropped one, which is not exotic in a repo with parallel package trees.

Only the sound direction remains — a read path that ends in the changed path, which is what an absolute path out of the run's mktemp checkout looks like. TestUnopenedChangedIsNotFooledByASharedTail constructs the collision and fails on the parent:

rcUnopenedChanged = [], want [pkg/db/secrets.go] — a shared tail is not a read

The gate's gcancel() is now deferred. Flagged as unverified rather than as a defect, which was the right call — and the honest answer is that I can verify it and would still rather not have to. The run has its own scope now, so the cancel fires on every exit. Whether the runner leaves a session lock or a goroutine behind on an abort is no longer a question this code depends on.

The fallback printed the wrong finish reason. Fixed; both the branch and the diagnostic read inc.

On the 9.3s/turn point: you are right that the test guards one direction only, and that is deliberate rather than an oversight — but it was only deliberate in my head, so it is now in the comment.

Too large — the ceiling leaves the soft budget, and nothing else would catch it. Hence the assertion.
Too small — turns cost more than the constant says, so the run reaches rcReviewSoftBudget before its turn cap. The soft budget fires, the conclusion is forced, and the incomplete path reports it. That direction already has a backstop, and it is the one the whole design wants: the wall clock binding rather than the turn count.

The three decisions are all real and all yours, so I am not resolving them in code:

Turn budget 20 → up to 45. More provider spend on large-PR reviews. The evidence for spending it: 9+ file PRs currently open 6.5 changed files and leave 8.4 unopened, at 39% of the clock.
KAI_PR_TITLE/KAI_PR_BODY lead the author context. Changes what the reviewer judges the change against, on every pod where kai-server injects them.
Every branch commit now enters the author context, so wip commit messages do too. That is the tradeoff for not judging a twelve-commit PR by its last commit.

One note on this review's own manifest: "What I opened — 1 file, 14 turns" with 3 of 4 changed files not listed — including both test files it then reasoned about in detail (it correctly identified that TestUnopenedChangedNamesTheSkippedFiles never constructs the collision case). Either the manifest is undercounting, or the reasoning about those files came from the diff rather than the files. Worth knowing which, given that manifest is the artifact this PR is built around.

Kai review

Kai Summary

Read through this one. One thing worth your eyes before it merges. 👇

Scope: I read kaicontext/kai-cli at the merged change (commit 358e333), focused on cmd/kai/review_commit.go, cmd/kai/review_commit_ground.go, and the new review_commit_budget_test.go. I could not see kai-server (the control plane that injects KAI_PR_TITLE/KAI_PR_BODY and that compares the manifest against diff.files), nor the agent runner's session-resume behavior beyond what the comments assert. I could not externally verify the 9.3s/turn measurement figure.

The rest of the read-through

What this change does: It (1) fixes the coverage gate's file-accounting to drop an unsound "shared tail" suffix match so skipped files can no longer escape detection; (2) wraps the gate's context cancel in a deferred-in-its-own-scope IIFE so it fires on every exit path of agent.Run; (3) fixes the conclusion-fallback diagnostic to print inc.FinishReason (current pass) instead of res.FinishReason (first pass); (4) scales the turn budget to the diff size with a ceiling; (5) replaces len(transcript) with an assistant-turn count; (6) prepends the PR description to author context; (7) makes rcAuthorContext use the whole commit range on non-merge heads. Overall this is a careful, well-commented change and the four items the author names are all done correctly. I have one minor concern and two decisions to surface.

Minor concern — the gate's stale FinishReason when the second pass is unusable (review_commit.go:919-943). When the gate runs and rcUsableCoda(second) is true, raw and inc.FinishReason are both updated — correct. But when the gate runs and the second pass is not a usable coda (ran out of turns mid-write), raw stays as the first pass's text, transcript is reassigned to res2.Transcript (line 911), and inc.FinishReason is left as the first pass's res.FinishReason (it is only updated inside the if rcUsableCoda branch). Then line 936 fires !rcUsableCoda(raw) — the first pass had no coda, which is why the gate ran — so the fallback calls rcConcludeFromTranscript over the gate's transcript and overwrites raw. That is mostly intended (the comment at 916-918 says the fallback still gets the gate's transcript). The only sharp edge: the diagnostic at line 940 reports the first pass's finish reason while concluding over the gate's transcript. If the gate's second pass died on FinishReasonTimeBudget, that mismatch is a wording issue, not a functional defect — the first pass had no coda regardless, so the fallback firing is correct. I'm noting it but not blocking on it.

Decision — the turn budget now scales and can grant up to 45 turns (review_commit.go:163-197). This changes how long every customer's review runs and how many turns it gets. The ceiling of 45 turns × 9.3s/turn ≈ 420s is inside the 540s soft budget by design, and TestReviewMaxTurnsScalesWithTheChange asserts that invariant. The 9.3s/turn figure is an external fact (measured on z-ai/glm-5.2 on 2026-09-09) that I could not confirm from this repo; the test catches drift if the constant is edited past the budget, but it cannot catch the constant being wrong today against a model I cannot observe. If the deployed model is slower than 9.3s/turn, reviews hit the soft budget instead of the turn cap — which the author argues is the desired degradation path. This is a deliberate tradeoff affecting every review's runtime; it belongs to a human to confirm the figure holds for the model CI actually exports.

Decision — the PR description is now read from KAI_PR_TITLE/KAI_PR_BODY and prepended to author context (review_commit.go:971-997). This changes what every customer's review is judged against: the PR description leads, commits follow, and a long description is truncated at 6 KiB with commits preserved. The change is gated on the env vars being non-empty, so local reviews and older control planes are unaffected. For any CI that sets these, the reviewer now tests the code against a different (and the author argues, correct) statement of intent. The comment asserts kai-server injects these into the runner; I cannot see kai-server from here, so I cannot confirm the injection exists or that the built-in workflow passes them on. If not yet deployed, this is a no-op today and activates later — worth confirming the server side is shipped.

Things done well: the shared-tail fix is exactly right and TestUnopenedChangedIsNotFooledByASharedTail constructs the real collision and would fail on the parent. The deferred-cancel IIFE is the correct idiom. The rcTurns fix and its test are sound and would catch the 2x overcount. rcUsableCoda correctly requires a parseable field after the marker, not just the marker. rcMergeFilesRead sorts and dedups. The rcAuthorContext multi-commit fix is a real correctness improvement and the test covers the non-merge head CI actually reviews.

This is ready to merge; the two decisions above are the author's to confirm, not defects blocking the code.

+				// files it opened are not lost either.

+					raw = second
+					inc.FinishReason = string(res2.FinishReason)


when the gate's second pass is unusable, inc.FinishReason is left as the first pass's reason while the fallback concludes over the gate's transcript, so the diagnostic at line 940 names the first pass's finish reason; minor wording mismatch, not a functional defect.

Two coupled corrections to the gate, from Kai's note that inc.FinishReason went stale when the second pass produced nothing usable. inc.FinishReason was only assigned inside the `if rcUsableCoda` branch, so a gate that ran and failed to write a coda left the manifest — and the diagnostic below it — describing the FIRST pass, which by then was not the last thing that happened. It is now assigned whenever the gate runs. How a run ended is how its last pass ended, whether or not that pass's answer was the one kept. That alone would have introduced a worse bug, so the second half matters: the conclusion fallback branched on `FinishReason == TimeBudget || no usable coda`. Once the gate can set FinishReason, a gate that died on the clock would fire that branch and overwrite a perfectly good first review with a transcript conclusion. The first clause is redundant anyway. It dates from before rcUsableCoda, when the test was a bare marker check — and a run that timed out has no usable coda by construction. The condition is now the ANSWER alone: !rcUsableCoda(raw). It covers every case the timeout clause was there for and none of the ones it should not.

fatihacet · 2026-09-10T15:16:24Z

Fixed in 60084fd. You called it a wording issue and were being generous — chasing it turned up a second, sharper problem underneath.

inc.FinishReason was only assigned inside the if rcUsableCoda branch, so a gate that ran and wrote nothing usable left the manifest describing the first pass, which by then was not the last thing that happened. It is now assigned whenever the gate runs. How a run ended is how its last pass ended, whether or not that pass's answer was the one kept.

That alone would have introduced something worse, which is the part worth flagging: the fallback branched on FinishReason == TimeBudget || !rcUsableCoda(raw). Once the gate can set FinishReason, a gate that died on the clock would fire that branch and overwrite a perfectly good first review with a transcript conclusion.

The timeout clause turns out to be redundant regardless. It predates rcUsableCoda, from when the test was a bare marker check — and a run that timed out has no usable coda by construction. The condition is now the answer alone: !rcUsableCoda(raw). Covers every case the timeout clause existed for, and none of the ones it should not.

On the two decisions, both are yours and I am not resolving them in code:

The 45-turn ceiling. Your framing is exactly right — the test catches the constant drifting past the budget, but cannot catch it being wrong today against a model it can't observe. Worth confirming z-ai/glm-5.2 is still what review_default_workflow.go exports before this becomes the default.

The PR description. The server side is not yet shipped — it is kaicontext/kai-server#238, open now. So this is a no-op until that merges and the next image pin carries this. Confirmed from that side: maxPRContextBytes is 8KB there against rcMaxAuthorContextBytes 8KB here, with the description itself capped at 6KB inside it, so the commits survive rather than the description eating the whole budget.

Partial codas discard findings

When the bounded coverage pass stops after emitting INTENT_MATCH or SUMMARY but before ISSUES, rcUsableCoda accepts that response and replaces the complete first-pass review. Transcript recovery is then skipped, so the parser publishes an empty-risks review and discards the first-pass findings.

Kai review

Kai Summary

Read through this one. 4 things worth your eyes before it merges. 👇

Scope: I reviewed kaicontext/kai-cli at commit 60084fd, focused on cmd/kai/review_commit.go, cmd/kai/review_commit_ground.go, and the new cmd/kai/review_commit_budget_test.go. I could NOT read github.com/kaicontext/kai-engine — the agent package's Result, Options, and Run live there, and two of this change's load-bearing assumptions rest on that repo. I name them below.

The rest of the read-through

What the change does: It scales the review's turn budget to the diff size (base 20 + 2/file, capped at 45), adds a "coverage gate" second pass that resumes the run's session to read changed files the first pass skipped, fixes the FinishReason/turn-count accounting the manifest reports, and folds the PR title/body from KAI_PR_TITLE/KAI_PR_BODY into the author context. The two headline fixes are sound: inc.FinishReason is now set whenever the gate runs (so the manifest describes the last pass that actually ran), and the conclusion-fallback condition collapsed from FinishReason == TimeBudget || no coda to !rcUsableCoda(raw) alone — which correctly prevents a gate that died on the clock from overwriting a good first review. I traced the four reachable scenarios (first pass good + gate dies on clock; first pass timed out + gate skipped; first pass good + gate produces coda; first pass no coda + gate produces coda) and the logic holds in each.

Concerns:

cmd/kai/review_commit.go:869 — the gate's correctness rests on agent.Result.SessionID and resumed-session transcript semantics I cannot verify. The gate only fires when res.SessionID != "", and it assumes res2.Transcript for a resumed session is the whole conversation (the comment at lines 903-907 calls these "assignments, not additions" precisely because adding would double-count the first pass's turns). Both are properties of kai-engine's agent.Run, which is outside this repo and not vendored here. If SessionID is ever empty when a session store is configured, the gate silently never runs; if a resumed transcript is not the full history, inc.Turns/inc.FilesRead undercount or the conclusion fallback sees a partial transcript. Nothing in this repo's tests exercises a real resumed session — every new test calls the pure helpers directly. This is the single biggest unverified seam, and it is exactly the limit of what I can see.
No test in the diff exercises the gate logic in rcRunReviewAgent (lines 868-933). Reverting the inc.FinishReason = string(res2.FinishReason) line at 924 or the !rcUsableCoda(raw) condition at 949 leaves every new test green, because every test drives a pure helper, not the integrated path. The two headline bugs are thus unverified by behavior — the tests cover the helpers the fix uses, not the fix itself. A test that would catch the stale-FinishReason bug needs to fake a second agent.Run returning FinishReasonTimeBudget and assert inc.FinishReason reflects the second pass, not the first; nothing here does that.
rcUsableCoda (around line 1240) accepts a coda carrying SUMMARY: with no INTENT_MATCH: (the test at line 81 confirms this is intentional). That coda skips the conclusion fallback and is then handed to rcParseReviewOutput at line 369. I did not fully trace rcParseReviewOutput's handling of a present-SUMMARY-absent-INTENT_MATCH coda within my turn budget — this is the one seam where "usable" (per rcUsableCoda) and "parseable" (per rcParseReviewOutput) could disagree, and a half-coda adopted by the gate could be mis-parsed downstream. Worth a quick check of that parser's missing-field behavior before merge.
cmd/kai/review_commit.go:958 comment overstates the bounding guarantee. rcMaxPRDescriptionBytes = 6KB caps the PR body, but the combined author context is then truncated at rcMaxAuthorContextBytes = 8KB at line 705. A near-6KB description plus the header text the function prepends leaves roughly 1.5KB for the commit messages before the 8KB cut. The comment says the cap is "so a long description cannot crowd the commit messages out entirely" — they survive, but can still be truncated, and TestPullRequestDescriptionIsBounded only asserts the commits appear, not that they appear uncut. Not a defect; the guarantee is weaker than the comment claims.
rcConcludeFromTranscript discards its ctx argument (line 1389: _ = ctx) and uses its own fresh 3-minute deadline. Pre-existing and intentional, but worth knowing the ctx passed at line 951 (the review's hard-deadline context) is inert there — the fallback's clock is independent of everything above it. Not a regression.

On external figures: the 9.3s/turn median, the 85-review sample, the 6% near-budget figure, and the model identifier z-ai/glm-5.2 are asserted in comments and are load-bearing for the ceiling's correctness (the test multiplies rcReviewTurnCeiling × rcObservedSecondsPerTurn against the soft budget). I could not verify these against any source in this repo; they are the author's measurement. The test will fail if the product exceeds the soft budget, which is the right guard, but the current 9.3 figure is unverified by me and would need re-measuring if the model tier changes — as the comment itself notes.

Decisions (not defects):

The turn budget now scales with the diff (base 20 + 2/file, capped at 45) instead of a flat 20. This raises the cost and wall-clock exposure of every large-PR review (45 turns × 9.3s ≈ 420s, inside the 540s soft budget but far closer to it than the old 187s). It affects every customer review run by the CI workflow. The author measured and justified it; the test guards the ceiling against the soft budget. The direction — more turns on larger changes, wall-clock reasserted as the binding limit — is a deliberate tradeoff that charges more compute per large review than before, and a human signed off via the commit.
rcWithPRDescription reads KAI_PR_TITLE/KAI_PR_BODY on every review-commit. When unset (local review, non-PR push, older control plane) nothing changes; when set (kai-server-injected), the PR description leads the author context and the commits follow. This changes what every CI-served PR review is judged against — from the commit messages to the PR's stated goal. Intended and documented, but it is a behavior shift for every customer whose control plane sets these vars.

Merge readiness: The core logic is correct and the intent is met. The gaps are an unverified engine contract (concern 1), no integration test that would fail without the headline fix (concern 2), and a rcUsableCoda/rcParseReviewOutput agreement I couldn't fully close (concern 3). None are proven defects from within this repo; concern 1 in particular is exactly the limit of what I can see. Your call, then merge.

Additional findings

I couldn't pin these to a line in the diff:

cmd/kai/review_commit.go (gate block 868-933) — no test exercises the integrated gate logic; reverting the FinishReason assignment or the !rcUsableCoda condition leaves every new test green, so the headline fixes are unverified by behavior.
cmd/kai/review_commit.go:~1240 vs :369 — rcUsableCoda accepts a coda with SUMMARY: but no INTENT_MATCH:; whether rcParseReviewOutput agrees on that partial coda is untraced and is the seam where "usable" and "parseable" could diverge.

the gate depends on agent.Result.SessionID being populated and on a resumed session's transcript being the whole conversation; both are properties of kai-engine's agent.Run, outside this repo, and no test in this diff drives rcRunReviewAgent with a faked second pass to confirm them.

+// rcMaxPRDescriptionBytes bounds the pull request half of the author context,


comment — claims the 6KB PR-description cap prevents crowding commits out of the 8KB author context, but a near-6KB description plus headers leaves only ~1.5KB for commits before the 8KB truncation at line 705; the guarantee is weaker than stated.

The sharpest of four findings: reverting either headline fix left every new test green, because they all drive pure helpers and the fix itself lives inline in rcRunReviewAgent. By this repo's own standard that is not coverage — the tests asserted the mechanism was configured, not the behaviour it was supposed to buy. So the decision is a function now. rcMergeGate takes the two answers and the second pass's finish reason and returns what to keep; rcNeedsConclusion takes the answer alone. Both rules are pinned, and I checked each by breaking it: forget the last pass's reason finish = "", want the LAST pass's reason "time_budget" make the fallback unconditional a complete first review needs no conclusion call, whatever the gate did ## The resumed-session assumptions, verified rather than asserted Two properties this change rests on live in kai-engine, which the reviewer cannot read and this repo cannot test. Both hold, and the comment now says where: resolveSession loads s.History() as the seed history on the opts.SessionID path and res.Transcript is assigned that same history, so a resumed transcript is the whole conversation; and res.SessionID is set whenever a session exists, which the review guarantees by always passing SessionStore — so the gate's SessionID guard cannot silently never fire. ## SUMMARY without INTENT_MATCH rcUsableCoda accepts it, so "usable" and "parseable" had to be checked against each other. They agree: rcParseReviewOutput keeps the prose and the issues and leaves match Unknown, which is the honest value for an intent the reviewer never stated — and prose plus issues means the bundle is not treated as an incomplete review. Now a test. ## The description cap is arithmetic, not a claim A flat 6KB inside an 8KB author context made "the description cannot crowd the commits out" true only approximately: a near-cap description plus the header left the commits a sliver, and the cut that took the rest happened in rcRunReviewAgent. The cap is now derived — rcMaxAuthorContextBytes - rcCommitContextReserve - rcPRDescriptionHeader — and the test asserts the three parts fill the context exactly and that the commits arrive whole rather than merely appear.

969d23d. Concern 2 was the one that mattered and it was right in a way I should have caught myself.

Every new test drove a pure helper, and the fix lives inline. Reverting inc.FinishReason = ... or the fallback condition left the suite green — the tests asserted the mechanism was configured, not the behaviour it was supposed to buy. That is the failure mode this repo's own reviewer prompt calls out by name, in a PR about the reviewer.

The decision is a function now. rcMergeGate(firstRaw, secondRaw, secondFinish) returns what to keep; rcNeedsConclusion(raw) takes the answer alone. I checked both by breaking them:

forget the last pass's reason:
  finish = "", want the LAST pass's reason "time_budget"
make the fallback unconditional:
  a complete first review needs no conclusion call, whatever the gate did

Concern 1 — the resumed-session seam. You are right that it is the single biggest unverified thing and right that this repo cannot test it. I verified it in kai-engine and put the citation in the comment so the next reader does not have to leave the repo either:

resolveSession loads s.History() as the seed hist on the opts.SessionID path, and res.Transcript is assigned that same history — so a resumed transcript is the whole conversation, and the assignments are correct.
res.SessionID = sess.ID whenever a session exists, and the review always passes SessionStore: gdb — so the SessionID != "" guard cannot silently never fire.

Concern 3 — SUMMARY: with no INTENT_MATCH:. Good instinct; they agree. rcParseReviewOutput keeps the prose and the issues and leaves match Unknown, which is the honest value for an intent the reviewer never stated — and prose plus issues means the bundle is not treated as incomplete (that test is prose == "" && no risks && no decisions && match unknown). TestSummaryOnlyCodaSurvivesTheParser pins the agreement.

Concern 4 — the comment overstated the bound. Correct, and the fix is to make the arithmetic carry the guarantee instead of the prose: the cap is now derived as rcMaxAuthorContextBytes - rcCommitContextReserve - rcPRDescriptionHeader, the test asserts the three parts fill the context exactly, and it asserts the commits arrive uncut rather than merely appear.

Concern 5 — rcConcludeFromTranscript discards its ctx. Pre-existing and deliberate: the conclusion is a grace period beyond the run, so hanging it off the run's exhausted deadline is what made it fail on PR#90. Not touching it here.

On the external figures: agreed, and that is why they are a named constant with a test that multiplies them. The 9.3 stands or falls with the model review_default_workflow.go exports, which is a decision I have left with the PR rather than resolved.

Kai review

Kai Summary

Nothing I'd call a defect, but 2 decisions to say yes to. 👇

I read kaicontext/kai-cli at the merged commit (969d23d / 01153f1): the full review_commit.go and review_commit_ground.go changes plus the new test file. One boundary I cannot read: kai-engine's agent.Options struct, agent.Run, and resolveSession — they live in the sibling module this repo imports, not in it. Two properties the coverage gate rests on (that a resumed session's Transcript is the whole conversation, and that res.SessionID is set whenever a session exists) are asserted in the diff's comments as verified there; nothing in this repo's call sites contradicts either, but I cannot see the engine source to confirm them myself.

What the change actually does: it scales the review turn budget to changed-file count (flat 20 → up to 45), adds a "coverage gate" second pass that resumes the session to open files the first pass skipped, prepends a bounded PR description (KAI_PR_TITLE/KAI_PR_BODY) to the author context, derives the description cap arithmetically so the commits arrive whole, fixes rcAuthorContext to include every commit on a non-merge multi-commit branch head (the CI case), counts assistant turns instead of messages, and extracts the gate's merge logic and conclusion condition into pure functions pinned by tests. My overall take: the extraction is the right call, the tests genuinely drive the rules, and I found no defects in the code I can read. Two human decisions (cost, judgment basis) reach outside the code and need a conscious yes.

The two extracted rules are the sharpest part and they hold. rcMergeGate keeps the last pass's finish reason whether the second answer is adopted or not — so the manifest describes the run that actually finished last, not a pass that was superseded. rcNeedsConclusion keys on the answer (!rcUsableCoda(raw)), not on the finish reason — so a gate that died on the clock no longer fires the conclusion fallback over a perfectly good first review, which is exactly the regression the old finish == TimeBudget || !contains(marker) condition would have caused once the gate could set inc.FinishReason. TestMergeGateKeepsTheRightAnswerAndTheRightReason asserts both directions, and I checked that reverting either rule fails it: the first case (good first, half second, timeBudget) asserts adopted == false, raw == good, finish == timeBudget, and !rcNeedsConclusion(raw) — break the finish-reason rule and the third assertion fails; make the fallback unconditional and the fourth fails. That is real coverage, not mechanism-was-configured coverage.

The parser/gate consistency is verified, not asserted. rcUsableCoda accepts a coda with SUMMARY: but no INTENT_MATCH:, and TestSummaryOnlyCodaSurvivesTheParser feeds exactly that shape through rcParseReviewOutput and asserts non-empty prose, one risk, a non-empty note, and match == finding.MatchUnknown. I read rcParseReviewOutput: with no INTENT_MATCH: line, match stays at its finding.MatchUnknown zero value, prose is everything before the marker, and ISSUES bullets are collected — so "usable" and "parseable" agree, and a SUMMARY-only coda is neither dropped nor misclassified as incomplete.

The shared-tail guard in rcUnopenedChanged is sound in the direction it keeps and unsound in the one it rejects, exactly as the comment claims. The exact match (read[c]) catches a bare-equal read path before the suffix loop runs, so HasSuffix(r, "/"+c) only adds absolute-path coverage (/tmp/tmp.aBc/db/secrets.go matches db/secrets.go); the mirror direction is deliberately not tested, and TestUnopenedChangedIsNotFooledByASharedTail pins the db/secrets.go / pkg/db/secrets.go case where only the shallower one was opened. Correct.

The cap arithmetic is exact: rcMaxPRDescriptionBytes (5888) + rcCommitContextReserve (2048) + rcPRDescriptionHeader (256) = 8192 = rcMaxAuthorContextBytes. TestAuthorContextReservesRoomForTheCommits asserts both the sum and that a worst-case description (3× the cap) leaves the commits intact and the whole string under the 8192 cut. The cap lives in rcWithPRDescription; the final rcMaxAuthorContextBytes truncation in rcRunReviewAgent can only trim the tail, which is the commits — the "supporting detail" the design says should give way. Consistent.

The gate's own clock is bounded: rcGateHeadroom caps at rcGateMaxBudget (4m) and floors at rcGateMinHeadroom (45s), so context.WithTimeout(context.Background(), left) cannot exceed the 20m hard deadline and cannot start with too little to produce a useful answer. The IIFE scopes gcancel so it fires on any exit from agent.Run, not only the clean one. The gate := opts shallow copy is safe — opts is not reused after the gate runs, the overwritten fields (SessionID, MaxTurns, Prompt, InjectedContext, SoftTimeBudget, SoftTimeBudgetExtension) are scalar/string/time.Duration, and the shared Hooks closure only writes to os.Stderr. No aliasing flows back into the first pass's result.

rcTurns counts RoleAssistant messages only; the test builds a user/assistant/tool/assistant/tool/assistant transcript and asserts 3, not 6. Correct, and it fixes the 2x manifest overcount.

One unverified external fact I want to name plainly, because the turn ceiling's correctness depends on it: rcObservedSecondsPerTurn = 9.3 is a measurement of the median turn cost on the model tier the CI workflow exports (the comment says z-ai/glm-5.2, measured 2026-09-09 across 85 reviews). TestReviewMaxTurnsScalesWithTheChange pins the arithmetic (45 * 9.3 ≈ 419s < 540s soft budget) and fails if the product leaves the budget, but the 9.3 figure itself is from outside this repo and I cannot confirm it. The design degrades gracefully if it is wrong in the slow direction: the soft budget fires before the turn cap, the review concludes, and the incomplete path reports it — which the comment itself notes is the desired backstop. So the failure mode is loud, not silent; the number is still the author's to keep current.

Two things in this change reach a customer and need a human's yes before it ships; neither is a defect:

The turn budget on a large change went from a flat 20 to up to 45 turns (for ≥13 changed files), with up to 4 more minutes of coverage-gate budget on top. This roughly doubles the maximum model cost per review on the largest PRs — more turns means more token generation billed — and it affects every customer whose review the CI workflow runs on a large change. The wall clock stays bounded by the existing 9m soft / 20m hard budgets, so it is not unbounded, and the author has clearly reasoned about the tradeoff (the entire comment block is that reasoning). But a per-run spend increase on the largest reviews is a billing-affecting decision the author should confirm consciously.

The PR description now leads the author context on every grounded review that carries KAI_PR_TITLE/KAI_PR_BODY — so the reviewer tests the code against the PR's stated goal rather than the commit messages, which is what the reviewer measured against before. The comment states kai-server injects these variables and the built-in workflow passes them on; that injection lives in kaicontext/kai-server, which I cannot read here. The fallback is safe (TestNoPullRequestDescriptionChangesNothing returns the commits unchanged when both are empty), so a pod that does not set them loses nothing. But the shift in what the reviewer judges against affects every review that does carry a description, and it is a judgment-basis change the author should confirm the control plane actually feeds.

Both are decisions the author described and clearly intended; I'm naming them because one touches billing and the other changes what the reviewer measures, not because the code is wrong.

Merge it. The extracted rules are pinned by tests that fail when broken, the cap arithmetic is exact and parser-consistent, the gate's clock is bounded and its cancel is deferred, and the two things that reach outside this repo either degrade safely or fall back to today's behavior. The turn-budget increase and the PR-description lead are human decisions about cost and judgment basis, not defects.

Decisions

Correct as written, but somebody should say yes to these:

The turn budget scales from a flat 20 to up to 45 turns on large PRs (plus up to 4m of coverage-gate budget), roughly doubling maximum per-run model spend on the largest reviews for every customer whose review the CI workflow runs; the wall clock stays bounded, but the cost increase is the author's to confirm.
The PR description now leads the author context the reviewer judges against (commit messages before, the PR's stated goal now) on every grounded review carrying KAI_PR_TITLE/KAI_PR_BODY, which the comment assumes kai-server injects; this repo cannot confirm that injection, and the fallback is safe, but the judgment-basis shift affects every review that does carry a description.
