Mark the round-1 safety claim as superseded.
This text says that a pre-boot temp cannot belong to a live PID. devlog/_plan/260819_response_state_temp_reclaim/011_audit_round2.md later identifies this claim as false for shared volumes, suspend behavior, and network filesystem timestamps.
Keep this audit history, but label the paragraph as superseded or replace the claim with the corrected safety argument.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win
Align the phase-1 documentation with the corrected implementation. The boot-time pseudocode must disable the floor for non-finite or future boot times rather than clamp them to the current time, because clamping can make the floor maximally aggressive. The crash-path explanation should also state that a process which produced a temp has already performed the one-shot reclaim; the defect is that the pass runs only once, grace hides predecessor temps, and per-pass limits restrict progress.

Define one truthful result contract for report and reclaim modes.
result.matched cannot support the text on Line 45. In src/responses/state.ts:565-642, matched increments after the filename match and before the regular-file, age, boot-floor, current-process, and liveness checks. A live-PID file, young file, current-process file, directory, or invalid match can therefore make the report say that abandoned files exist.
The sample also reads result.bytes, but the supplied result has bytesRemoved, not bytes. Line 70 through Line 71 introduce wouldRemove and bytesReclaimable, but the plan does not add or aggregate those fields in ResponseStateTempRecoveryResult and reclaimAbandonedResponseStateTemps at src/responses/state.ts:978-997. This can cause a type error or an incorrect report.
Define and initialize the dry-run fields, aggregate them across both directories, and use them in the report. Make inspectAbandonedResponseStateTemps() call the same wrapper with dryRun: true; do not create a second selection implementation.

Align reclaim output with recovery accounting.
In src/responses/state.ts:565-642, an ENOENT race increments removed but does not increment bytesRemoved. Line 42 can therefore report reclaimed 1 file(s), 0 B freed. This is valid only if bytesRemoved means bytes unlinked by this invocation, not bytes freed globally. State that meaning or add separate accounting for files that were already absent.
The same code increments failed for every non-ENOENT unlink error. The text on Line 43 is too narrow for permission or I/O failures. Use “could not be removed” unless the result records error categories. Add doctor output tests for ENOENT and a non-ENOENT failure.

Report scan truncation instead of claiming a complete inventory.
The dry-run branch does not increment removed or failed, so it can bypass maxCleanups. The existing loop in src/responses/state.ts:565-642 still stops at maxEntries and at deadlineMs when configured. Unless inspectAbandonedResponseStateTemps() explicitly overrides those limits, the doctor can undercount files or report “none abandoned” after an incomplete scan.
Add truncated metadata with a reason such as maxEntries or deadline, and print a partial-scan warning. Alternatively, define a separate operator scan budget with an explicit completeness guarantee. Add tests for both limits.

Do not treat pre-boot mtime as proof of process ownership.
The implementation and the round-1 audit rely on the same incomplete identity model. A PID can be reused across or within a boot, and shared-volume writers are not represented by the local boot clock.

Make periodic scans progressive and enforce one tick budget.
Each reclaim call starts directory iteration from the beginning and stops at maxEntries. If a directory contains more than 512 non-matching entries before a stale temp, stable directory ordering can prevent that temp from ever being inspected. The plan says the next tick resumes, but this implementation has no cursor or continuation state.
The wrapper also resets maxEntries, maxCleanups, and deadlineMs for every directory. Two directories can therefore consume 1,024 entries, 128 cleanup attempts, and two 25 ms windows in one liveness tick.
Carry scan progress between ticks and carry the remaining entry, cleanup, and deadline budgets across directories. Add a regression test with more than 512 leading entries and a stale temp after the boundary.

retain per-directory scan cursors between periodic ticks, resume after
maxEntries, and reset cursors when a directory scan completes or becomes
invalid. Track one shared remaining entry, cleanup, and deadline budget across
all directories in a single reclaim call rather than reusing the configured
limits for each directory. Add a regression test covering more than 512 leading
non-matching entries followed by a stale temp, verifying a later tick reclaims
it.

Make the grace-period test enter the boot-floor path.
Lines 1667-1673 create a file at the current time and set bootTime to 24 hours earlier. The file does not predate boot. recoverStaleResponseStateTemps therefore calls isProcessAlive instead of bypassing liveness through predatesBoot.
The test passes even if the grace check is removed. Set the fixture mtime so that predatesBoot is true while the file age remains below the 15-minute grace period. Use the injected clock or inspection seam if needed.

In `@tests/responses-state.test.ts` around lines 1664 - 1677, Update the test
around recoverStaleResponseStateTemps so the temporary file’s mtime predates the
injected bootTime while remaining younger than the 15-minute grace period, using
the available clock or file-mtime seam. Preserve the existing assertions that
the file is matched but not removed, ensuring the test exercises the boot-floor
path and grace-period ordering.
…cates An early break abandons the enumeration generator instead of resuming it, so the finally that closes the directory handle never runs. The periodic reclaim truncates by design -- entry cap, cleanup cap, wall-clock deadline -- which turned that into one leaked handle per truncated tick. Route every early exit through a stopScan() helper that calls iterator.return() before returning, and add a regression that fails when the fix is reverted. Also repairs the deadline test's oracle. Its fake clock started at 0 while the fixtures carried real epoch mtimes, making every computed age negative, so the files survived the 15-minute grace whether or not a deadline check existed -- the test passed against its own ablation. Anchor the clock to real time and add an explicit unbounded-run assertion so the deadline is the only reason nothing is removed.

Summary
Abandoned
responses-state.json.ocx.<pid>.<seq>.tmpfiles could accumulate without bound — a field report described ~19.6 GB on one machine, growing per reboot.recoverStaleResponseStateTempswas already correct. The defect was when it runs and what it skips:schedulePersistsite (:897,:929,:956,:971,:1214) is downstream ofensureLoaded, so a process that abandons a temp has already had its only look. The 15-minute grace then hides the temp its predecessor's crash just produced, andmaxCleanupscaps one pass below a large backlog. A restart loop accumulates monotonically.This PR fixes both:
