The comment corrections are accurate and in scope: verified against scan.go that hashWorker's results-send branch is reachable and that stop() cancels before draining, the walkClock and poolUnwind
claims hold, and the constant rename is complete with its value
unchanged. Three policy defects block merge.
The commit message body contains a bare #6 ("re-review of #6").
Bare issue references are not allowed outside the required (closes #N) title suffix. Acceptable: the full URL https://git.eeqj.de/sneak/sfdupes/issues/6.
The new TODO.md Completed Steps entry is four physical lines; the
limit is three (what landed, date, link). Acceptable: drop the
branch name — it is not part of what-landed/date/link — so the entry
wraps to three lines or fewer.
The commit message body runs to roughly 142 words against the
~120-word ceiling. Acceptable: tighten the body below it.
Disclosure: make check did not complete within my time budget under
shared-host lock contention, so I did not confirm a green gate; the
change is comments plus one constant rename with no remaining
references to the old name, so no compiled behaviour changes.

Re-checked against next, which changed the code under four comments:
walkClock: now also covers the mid-hash tests, whose cancellation lands in the hash phase, not the walk.
walkCancelInFlightFiles: described as an upper bound, since the walk now stops mid-directory on cancellation.
hashWorker note: claims only its own two branches are tested, not every pool branch, because two walk checks have no test that fails without them (filed as #81); also dropped "freed by the drain", since a parked worker leaves on the cancellation itself.
File header: scan_test.go is now over 1,600 lines.

cancel_test.go, the paragraph added to the TestHashWorkerDropsQueuedRuns doc comment: it says TestScanHashWriteFailureUnwindsPool strands every worker on a full results channel and that both of hashWorker's cancellation branches have a test. On the current tree neither is true. The results channel is not always full when stop() runs, so that test reaches the results-send branch in some runs only. No test fails when that branch is removed, because stop()'s drain frees a parked worker anyway. TestHashWorkerDropsQueuedRuns catches removal of the other branch (the drop check) only about half the time: a cancelled worker that hashes the run anyway then picks at random between sending the result and leaving. Acceptable: say that the results-send branch is reachable through stop() and that the test reaches it only when the workers fill the results channel first; drop "strands every worker" and "both ... have a test"; file the missing tests as an issue, the way #81 was filed.
cancel_test.go, the poolUnwind comment: it says the tests that use it turn a pool that ignored its cancellation into a failed assertion. TestInterruptContextCatchesSIGTERM uses it to bound a signal cancelling the scan's context, which involves no pool. Acceptable: a comment that is true of every use.
PR body: item 2 of the definition of done in #33 asks for the mutation re-check to be repeated and reported in the PR. The PR skips it as a judgement call, and that check is what finds item 1. Acceptable: repeat it on the rebased tree and say so in one line in the PR body.
The branch no longer rebases cleanly onto next: TODO.md Completed Steps conflicts. Acceptable: rebase, with this entry at the top.

Fix the comments the re-review of
#6 found misdescribing their
tests; no test's behaviour changes.
State the property the walkClock tests rely on, that the index load's
Done cost does not grow with the record count, instead of a wrong fixed
figure. Describe poolUnwind so it is true of every use, and mark the
tests that have no bound. Record that hashWorker's results-send exit is
reachable through stop but has no test that fails without it. Rename
walkCancelInFlightDirs to walkCancelInFlightFiles, since it counts
files. Note at the top why the file departs from the
one-test-file-per-source-file convention.

Rewritten: the results-send exit is reachable through stop(); the tests that stop a scan mid-hash reach it in some runs only (a panic injected there fires in TestRunScanInterruptedMidHash as well as TestScanHashWriteFailureUnwindsPool, so the comment names no single test); no test fails without it; TestHashWorkerDropsQueuedRuns catches a removed drop check in some runs only. Missing tests filed as #83.
poolUnwind comment now true of every use, the SIGTERM wait included, and no longer claims every unbounded test says so (the mid-hash scans are unbounded too).
