…uires (#4599) The #5140 recovery test proves forkSnapshot reconstructs a non-retained parent's raw tail from the UNIFIED index — but it never pinned its own storage mode. Under the CI storage baseline (preload-storage-baseline.mjs sets BILI_STORAGE_UNIFIED=legacy for the broad corpus) no unified rows exist, so the reconstruction has no source and forkSnapshot fails closed with 409 SNAPSHOT_UNAVAILABLE. Deterministic, not a flake: reproduces 100% on master and any merged branch with BILI_STORAGE_UNIFIED=legacy, passes without it (default shadow). Pin full like the sibling persist tests and restore the ambient value afterwards.

ci-fixes at 67f8e89 still leaves four Windows shards red, and all four deltas already exist on PR #5178. This ports the missing hunks so the convergence branch actually converges. 1. `test (windows-latest, 2x, 3)` — #5103. `UnifiedShadow` builds its db path as `${dir}/index.db`, so the open-failure warning reads `C:\...\sessions/index.db`. `issue5103` asserts the warning contains `path.join(dir, "index.db")` — `...\index.db` on win32 — so a mixed separator never matches. `path` is already imported at :30 and the db is opened through the same join, so POSIX output is byte-identical. 2. `test (windows-latest, 22, 4)` + the 4788 leg — #4739/#4788 teardown. The suites arm a real `SessionStorage` under `BILI_STORAGE_UNIFIED=full`, so the sidecar is still open at teardown. `cancelAll()` clears timers and the build map but never closes the shadow; Windows refuses to unlink a directory holding an open file (`EBUSY`/`EPERM` on `index.db`). Use `closeQuietly()` — cancel, then close — in the short-lived-store teardown. 3. `test (ubuntu-latest, 24, 3)` + `(windows-latest, 22, 2)` — #5155. Both cold-rebuild cases waited for the debounced durable flush with a fixed `setTimeout(20)`. A millisecond budget is a deadline a loaded runner can miss, and the miss is an honest `409 !== 200` from a one-turn-stale table. Await the settle itself: `afterNextFlush("conv-ptrs")` resolves once the armed save lands. 4. `test (ubuntu-latest, 22, 3)` — #4788 verdict deadlock. `afterNextFlush` parks a resolver in `flushWaiters`, and the only thing that drains it is the debounce timer — which is armed `unref?.()`. Once that timer is the last pending handle the loop drains, the promise never settles, and node reports `Promise resolution is still pending but the event loop has already resolved`. Keep the timer referenced exactly while a waiter exists (`ref()` on waiter registration; the host-upkeep default stays unref'd). Both view hunks and the two test-teardown hunks are byte-identical to the ones already on PR #5178, so this converges the branches instead of inventing a third variant. Verified locally: `npx tsc --noEmit` clean; issue4788 0/4 -> 4/4; issue4739 4/4; issue5103 5/5; inc-canonical-pointers 3/3. The `cancelAll` -> `closeQuietly` hunk has no local negative control: reverting it keeps Linux green because `EBUSY`/`EPERM` only fire where an open handle blocks unlink. That control can only run on a Windows lane — stated rather than papered over. The #4788 arm's own reader is confirmed instead: `cancelAll()` leaves `index.db`, `index.db-shm`, `index.db-wal` in `/proc/self/fd` while `closeQuietly()` leaves none (probed directly).
…e settle (#4599) The turn() helper arms scheduleSave whose debounce timer is unref by design (persist.ts: a pending save must not hold the process open at shutdown) and then awaits afterNextFlush. Nothing else in that await is refd, so in a node:test child whose only surviving handles are unref sockets the event loop drains before the 50 ms debounce fires and the settle promise never resolves: all four subtests fail with "Promise resolution is still pending but the event loop has already resolved" / cancelledByParent. Reproduced deterministically on master 44067a5 AND on pre-merge ci-fixes 67f8e89 (standalone run, exact CI preload chain), while the same file has passed some CI legs by ambient-liveness luck - a born-flake per section 7.2 (no environmental luck). The pin at 67f8e89 does not touch this path. Fix: arm a refd 25 ms keep-alive interval around the afterNextFlush await (cleared in finally) so the debounce fires deterministically on every host. Test-only diff; production settle semantics untouched.

(ai: deepseek/deepseek-v41-flash) Merge order: #5262 must land on
|
| shard | delta in #5262 |
|---|---|
test (windows-latest, 24, 3) |
src/storage/shadow.ts: ${dir}/index.db → path.join(dir, "index.db") (the #5103 win32 separator assertion) |

test (ubuntu-latest, 22, 3) |
src/persist.ts: keep the debounce timer ref()'d while an afterNextFlush waiter exists |
Why the teardown hunks matter (portable proof, no Windows needed)
cancelAll() (src/persist.ts:3230) clears timers and the build map but never closes the shadow. /proc/self/fd shows it directly:
cancelAll: before=["index.db","index.db-shm","index.db-wal"] after=["index.db","index.db-shm","index.db-wal"]
closeQuietly: before=["index.db","index.db-shm","index.db-wal"] after=[]
Three handles survive cancelAll(), zero survive closeQuietly(). Linux unlink permits deleting open files, which is exactly why a Linux-only run cannot fail without this probe.
The #4788 timer host has a deterministic repro
issue4788 on 67f8e894 pass 0 / fail 4
+ timer-ref hunk from #5262 pass 4 / fail 0
revert only that hunk pass 0 / fail 4
afterNextFlush parks a resolver in flushWaiters; the only drainer is the debounce timer, armed timer.unref?.() at src/persist.ts:2769. Once it is the last pending handle the loop drains and the promise never settles — Promise resolution is still pending but the event loop has already resolved.
Ordering suggestion
Merge #5262 → ci-fixes, then #5208 → master. If #5208 already merged, the same four hunks can be replayed as a supplement (they are byte-identical to commits already on #5178, so no new variant is invented).
I cannot push to ci-fixes or merge anything (permissions.push == false, permissions.maintain == false; AGENTS.md §4 also forbids agents merging) — hence a PR against your convergence branch rather than a direct commit.
…ts ref-tracking fix (#4599) PR #5262 fixes #4788 at the source: scheduleSave now leaves the debounce timer refd while flush waiters exist (and afterNextFlush refs a pending unrefd timer when a waiter registers), so the settle is deterministic for EVERY caller on every host. The 25 ms keep-alive interval added in a3019b0 only patched this one test file and is redundant now; removing it leaves one mechanism instead of two. The comment stays: without it a future reader re-adds the interval or deletes the persist.ts tracking as dead weight.

(ai: deepseek/deepseek-v41-flash) This PR now carries the four-shard CI convergence work — and lands cleanlyStatus note so whoever merges knows what is inside. #5262 (the four remaining master-red lanes) was merged into
Evidence recorded in #5262: Merge-order finding (matters for this PR)I simulated the real landing order on a scratch tree from master
So: merging this PR first is the easier order. #5178 then rebases with three comment-only conflicts instead of resolving real behaviour, and the two sets of fixes compose without a semantic conflict (unlike #5216 x #5178, where the merge is textually clean but 3 tests go red — documented on #5216). |

Five red lanes, two distinct root causes:
1. Config-surface drift from #4788 D2 (4 lanes)
#4788 D2added the per-session resident hard cap — config fieldsessions.hardMaxBytes+ envBILI_SESSION_RESIDENT_HARD_MAX_BYTES— but never registered the surface: no YAML seed entry, no LIFECYCLE.md row, and only a hand-edited EN-onlyCONFIGURATION.mdrow that diverged from the generator. That tripped:config-surface-guard(missing seed key)docs-coverage(undocumented env var)lifecycle-ledger-guard(unregistered env var)docs-sync(regenerated output diverges from committed artifact)Fix: add the YAML seed entry (restoring the author's original EN wording + the #4792 decision ref + honest dynamic default), the matching ZH rows, and the LIFECYCLE.md §2 ledger row; regenerate the config docs so the artifact matches the seed again. Docs-only; no behavior change.
2. Stale terminal-stamp assert in the #4666 mysql contract (1 lane)
The #4666 suite's terminal-stamp asserts were moved to v9 when the schema advanced, but the concurrent-boots lock test's final assert was missed and still expected v8. With
MYSQL_SCHEMA_VERSION = 9(#4796 zero-ref index — index-only, no row change), the migrator legitimately stamps 9 after the lock frees, so the assert fired'9' !== '8'. Bumped to 9 to match the three sibling asserts; the lock-serialization discriminators (mid-flight stamp 7, rowCount 8, dedup collapse) are untouched.Verification is by remote CI (this run); local targeted repro confirmed all four doc/config guards pass.
Coordination: #4599.
