Step B of the #2923 plan: move the idle maintenance tick's work onto wakes and deadlines, so C can remove the tick. One PR with separate commits, as proposed in #2923; each commit can be reviewed and measured on its own.

The session part moved to #3265. Session maintenance (run_due_maintenance, planned here as commit 3) gets its deadlines in its own PR under #3265, using the due times MDK already saves, with no migration. It stays on the 15 s tick in this PR. The tick stays: removing it is PR C.

Commits

0. 77c4719 rewraps the housekeeping batch's doc comment (the nit from Stop repeating finished housekeeping on an idle maintenance tick #3035's review).

1. 397a6bb: the KeyPackage read-only check, and per-account wakes.

   • Engine::discard_private_key_packages opened a writer transaction on the session database on every tick, whether or not a KeyPackage had expired. It now reads first and writes only when one is to go. The received side's expiry DELETE checks first too.
   • The worker's storage telemetry only observed the app database, so Stop repeating finished housekeeping on an idle maintenance tick #3035's idle test could not see that writer. The engine's connection now records its writer begins under a new runtime operation, storage_session_write_begin, and the idle test asserts it stays at zero.
   • Presentation wakes were app-wide: one account's chat-list, message, avatar or attachment change ran every account's passes. Each account now has its own wake. Shared profile and directory changes, and attachment controls, still wake every account.

2. 0a1f1e5: the per-account timer for recovery and post-join, the watchdog, and compaction spacing.

   • The tick no longer runs the recovery seam and the post-join advance. Each runs once when the worker opens, then when an event wakes it, and again 15 s later while it still has work. With none, it rests.
     • Recovery has work while an epoch-gap arm write is buffered, the replay generation is not authorized, delivery loss blocks the cursor, or the ledger holds an epoch-backfill intent or a recovery demand.
     • Post-join has work while a collection is in progress, or a group's post-join fetch or catch-up is open. A new storage read, post_join_work_owed, answers that in one query instead of reading every group.
     • Wakes: the receive and convergence seams already run the recovery seam inline, and a join advances post-join inline. The client flags each inline run and the worker re-arms from it. A new replay generation wakes recovery; maintenance pausing or resuming wakes post-join.
   • The watchdog: each tick checks every scheduled job. One with work but no wake and no deadline pending is a missed wake: it is counted under its own runtime operation, logged once per job per worker, and run. Runtime operations have no dimensions, so the job is in the name: watchdog_missed_wake_recovery, watchdog_missed_wake_post_join (and, from commit 4, one per pass).
   • Compaction spacing: a rolled-back VACUUM waits 1 minute before its next attempt, then 10 minutes. The third rollback still ends the attempts for the ownership (MAX_COMPACTION_ROLLBACKS), so the 1 h step from the proposal would never be reached; I left the cap alone rather than raise it.

3. (moved to Stop the 15-second maintenance wake on idle accounts #3265) Session maintenance's deadlines. The numbering is kept so earlier review comments still match.

4. 6c6510f: the attachment, avatar and presentation passes get their own deadlines.

   • The tick no longer sets the passes due. Each runs when an event wakes it, and otherwise at the deadline its data gives, armed after a run that left nothing to repeat at once:
     • attachment: the earliest acquisition due among its candidates (a request, a lease end, a retry, a deferral or a readmission backoff), the earliest acquisition expiry, and the earliest partial prune time with the storage-parked exemption; and at least hourly;
     • avatar: the earliest avatar acquisition due;
     • presentation: nothing timed.
   • Work no column announces is still polled every 15 s while it exists: a staged upload, a row parked for free disk space (nothing signals free space), a media sweep batch still running, and presentation rows that cannot be applied yet. A row already due that the pass could not take (no permit or slot free) waits for the completion that frees one, or 15 s.
   • The watchdog checks the passes too. New storage reads: attachment_work_schedule, avatar_work_schedule, chat_presentation_work_pending.
   • After a failed unlink or another connection's commit, the media sweep now runs at the next attachment pass, at most an hour later instead of within 15 s: this avoids retrying a stuck file every tick, and the only effect of the wait is an orphaned file staying on disk a little longer.

5. 7625b32: every remaining tick job moves onto the worker's own schedule. Each runs when an event wakes it and at the deadline its data gives, and the watchdog checks each:

   • local submissions keep their own wake and retry; a failed read now retries in 15 s instead of waiting for the tick;
   • the content-report backfill and legacy promotion run batch after batch until done, then never again for the opened database; a failure retries in 15 s;
   • device pairing runs every 15 s only while pairing state exists (in memory, or a row in device_groups, device_group_joins, device_group_moves or device_links), and never with pairing compiled out or device groups off;
   • the compaction and housekeeping batch run at their in-memory deadlines (keep-media, the hourly recheck, a compaction retry), every 15 s while a migration, the startup truncate, keep-media more or a flagged compaction needs it, after each attachment pass, and within 15 s of a media row deletion elsewhere;
   • the KeyPackage catch-up runs at the refresh deadline its lifecycle holds (refresh_at, or a week after publication; new key_package_maintenance_next_due), and is woken by what changes it without time passing (below);
   • push samples fetch time every 15 s only while a join window is open, an announce is owed or a repair ask is held. The fetch clock counts only when sampled, so this is polling by design. An idle account no longer samples it, so a token change outside a join window goes out at once as a plain self-update, the always-valid form MDK already uses after a reconnect, and the announce it owes follows within about 30 s; no notification is missed, at the cost of one extra commit per group on a token change (an_idle_token_change_goes_out_plain_and_its_announce_follows);
   • history dispatch runs at its earliest upload, fetch, backup-pass or condemned-blob deadline, after each media completion, and when a history delivery is owed, parked or backed off. The delivery due columns (blossom_due_at, fetch_due_at) have no index; the reads scan tables that hold one row per group and sibling at most. An index may be needed once device groups ship.

   The tick now runs only session maintenance (run_due_maintenance, which Stop the 15-second maintenance wake on idle accounts #3265 moves) and the watchdog. Its redundant subscription-refresh fallback goes: every worker turn already rechecks it.

   KeyPackage catch-up triggers that aren't timed:

   • a sign-in check that finds the slot superseded or emptied: wakes it (a_foreign_publication_in_its_own_slot_is_replaced asserts the wake, and that a check finding nothing does not wake it);
   • the slot's withdrawal at sign-out: wakes it (asserted in the sign-out test);
   • a capability or device-tag change: these happen inside session maintenance, and every maintenance pass wakes the catch-up. Not tested on its own;
   • consumption by a Welcome is not a trigger: a consumed current KeyPackage stops the catch-up rather than starting it.

   None that I found fails to wake the worker.

6. 4d1ed51: failed history retries are spaced, and the watchdog test is steadier. A history upload or fetch that failed without writing its deferral arms a 15 s retry instead of being woken again at once. A later completion that wakes dispatch may retry it sooner, at most once per completion.

7. c314ddc: docs. The telemetry rows for the housekeeping batch and the passes describe the scheduled triggers, and storage-format-v2.md describes legacy promotion's cadence: one batch per worker turn until the sweep completes, behind the worker's commands, inbound delivery, convergence and passes, each a short transaction that releases the write lock.

8. 16ed525: housekeeping's deadlines run on tokio's clock, and the idle test settles startup work (see "Idle test" below).

9. 15df181: the push clock, housekeeping and wall-clock deadlines stay honest when idle (see "Second review fixes" below).

10. d01d1ba: the push clock's staleness boundary, and tests for the watchdog's push read, the announce after a token change and the housekeeping retry (see "Third review fixes" below).

Rebased on master

Rebased onto master at a7bcb48cf. #3374 now wakes the worker when an upload promotion finishes, and #3380 has it run a follow-up pass after a skipped batch, so the attachment pass no longer polls for a running promotion or a held promotion cursor (commit 4), #3375 changed create_group to return the members it resolved, so two tests on this branch take the group from its operation (commit 9). Both CHANGELOGs keep master's entries and these, and the telemetry doc lists a promotion batch's completion among the pass's triggers.

Third review fixes

From an independent review of 9acfeda06:

• Staleness boundary: a last look counts only while it is less than 30 s old, so a look exactly one step old no longer counts, and the worker test rests for three quiet samples, past that boundary (it failed about once in 27 runs sitting on it).
• Watchdog for push: the_worker_samples_push_timing_only_while_owed now writes an owed announce straight to storage with the worker's own per-turn wake turned off in the test, and the next tick's watchdog counts one missed wake and runs the Push job. It first waits two quiet steps, so a 15 s retry left armed by the run that sent the announce has fired and cannot run the job before the watchdog looks. It fails with the watchdog's Push read disabled, and passed 250 of 250 stress runs.
• Token changes: both token-change tests now assert that the announce follows once the device can fetch again and that the group owes no announce afterwards. After a suspend, no announce goes out on the first look after the gap.
• Housekeeping retry kept: a media row deleted outside the attachment pass, such as an abandoned upload, wakes no job, so housekeeping still looks again within 15 s after a deletion. a_media_deletion_outside_the_pass_brings_housekeeping_back_within_15_s fails without the retry.
• Test override: the push clock's test override is keyed by the account's data directory and removed by a drop guard, so a failed test leaves nothing behind for another.

Second review fixes

From an independent review of 622d32db5:

• Push fallback: an idle worker stops looking at the push fetch clock, so a clock that settled once stayed settled however long it went unread, and a token change could go out as an announce after the device lost its relays or was suspended. A last look more than one step (30 s) old now says nothing about now, and a gap longer than a step restarts the watched stretch. a_token_change_after_idle_and_lost_relays_goes_out_plain and a_token_change_after_a_suspend_goes_out_plain cover both.
• Repair replies use the same check, so after a suspend gap a repair decision also waits for 15 s of watched time again (a_repair_decision_waits_for_a_fresh_watch_after_a_suspend).
• Worker push test: the_worker_samples_push_timing_only_while_owed drives the real worker on a held clock: a token change goes out plain, wakes the Push job once, and its announce follows within two 15 s samples, one run per sample, with no missed wake. It fails with the per-turn wake or the re-arm disabled; the watchdog's owed read is now one function, and the_watchdog_reads_owed_push_timing fails with its Push check disabled.
• Housekeeping: its schedule and the watchdog's owed read come from one function, which owes nothing with cursors frozen or the account's storage unreadable, where the batch never runs (housekeeping_owes_nothing_where_its_batch_cannot_run).
• Suspend: deadlines stored as wall time (the avatar and attachment passes, history dispatch, the KeyPackage catch-up) became a timer once, on a clock that stops while the device is suspended. A job now carries its wall time beside its deadline: the worker sleeps toward it at most 15 minutes before looking again, runs it once wall time reaches it, and the watchdog compares wall with wall, so a suspend neither delays the work by more than that nor counts a miss.
• Idle test: every watchdog counter is checked from the first tick, warm-up included.

First review fixes

From an independent review of the previous head, 3263bdfb1:

• Relay fence (Wake the recovery runner when a late EOSE fences a group #3349): every move of the adapter's fence ticket now sends on the owner's replay watch. The replay supervisor admitted boundaries with no send of its own, and with the tick's recovery pass gone an idle account would not have noticed. admitting_a_fence_wakes_the_replay_watch fails without the send.
• Watchdog rule: a missed wake is work due with no wake pending and no deadline within 15 s. Before, any deadline hid a miss, and the attachment pass, housekeeping and history dispatch always arm one (up to an hour for attachments). owed_work_behind_a_far_deadline_is_a_missed_wake covers it.
• Push: the trade-off above, with its test. The push fetch clock now reads its time through a test-only hook, so the test steps it 15 s per sample instead of waiting real time; the test timing baseline is unchanged.
• Bisectability: the reconnect re-arm and the account-wake label fix now live in the commits that introduced those bugs (2 and 1); every commit builds and passes clippy on its own.
• Cleanups: per-account wake entries no longer outlive their worker; the recovery seam answers whether it left work from its own reads, so a receive no longer repeats them; comments on the replay wake, the implicit yield after a batch and history retry spacing are corrected.

Not changed, for C to know: post-join stays owed for groups its advance skips (no route, nothing required, unrecoverable), and recovery stays owed while offline or while a demand backs off. Neither is new, but those accounts do not go idle.

Idle test

idle_ticks_take_no_writer_and_spawn_no_housekeeping failed about once in fifty runs under load, on this branch and on 3263bdfb1 alike, with one housekeeping run inside its measured ticks. Two causes, both fixed in commit 8:

• Housekeeping's deadlines (keep-media, the hourly recheck, compaction spacing, the sweep rescan) ran on the real clock while the worker's schedule and the test run on tokio's, which the test holds and steps 15 s per tick in a few real milliseconds. They now use tokio::time::Instant, which is the real monotonic clock in the shipped app. The keep-media sweep's work budget stays on the real clock, since it bounds real work in a blocking task.
• The attachment pass polls while its startup sweep or promotion runs, and those finish in real time, so under load its last poll could land one tick after them, inside the window, and wake housekeeping. The test settled a fixed two ticks; it now ticks until four in a row run no pass and no housekeeping.

After both: 25 of 25 under a parallel cargo build, and 15 of 15 rounds of the runtime and attachment tests run in parallel (before: one failure in six). The test's failure message now names, for each housekeeping run in its window, its trigger, the poll flag that held, its deadlines, and the held and real time since the worker opened.

Separately, automatic_group_recovery_tests::app_retry_rearms_halted_job fails under parallel load on this branch (1 in 10) and on 3263bdfb1 (2 in 10) alike, Pending { attempts: 1 } against Pending { attempts: 0 }. It passes alone, and is not touched here. Likewise chat_list_window::tests::archive_and_anchor_loss_recover_neighbors_then_reset_without_stale_splicing failed once in 10 parallel rounds on this branch, against 0 in 10 on master, and passed 100 of 100 alone; it has one account, for which this branch's per-account wake reaches the same worker as the app-wide one did.

The tick and the watchdog in C

After commit 5 the tick runs only session maintenance, which #3265 moves, and the watchdog's fallback. Once #3265 lands, C deletes the tick and the watchdog together, once every watchdog_missed_wake_* counter has stayed at zero through the nightly soak. It does not keep a slower fallback timer: by then the counters have shown it has nothing to catch, and a slow fallback would only hide a missed wake added later. The counters go with it.

#3238

#3238 is fixed on master by #3262, and this PR is rebased onto it. Commit 2's recovery wake path never depended on it: while the adapter is inactive (offline, or no relays) the replay generation never authorizes, so recovery stays "owed" and keeps the tick's 15 s cadence. Since #3262 each of those repeat passes returns early and writes nothing. The idle test's replay-flush exclusion went with #3262; it now asserts no app or session writer at all.

Writer transactions on idle ticks

Offline idle account (the idle-tick test: no relays, three ticks after startup), every BEGIN IMMEDIATE on any connection captured with its call stack (a local measurement patch, not committed). Counts are over the three ticks.

On master as it now stands (4d1fee0, with #3262):

Source	Database	master	this PR (ac08e6b)
KeyPackage discard (Engine::discard_private_key_packages)	session	3	0
Total		3	0

Before #3262 the same test showed what each commit changed (master at 8e0cd0f, three ticks):

Source	Database	master	commit 1	commit 2	commit 4	commit 5
#3238: replay flush via the recovery seam	app	9	9	9	9	9
#3238: replay flush via the runner turn	app	6	6	6	6	4
KeyPackage discard	session	3	0	0	0	0
Total		18	15	15	15	13

Commits 2, 4 and 5 cut work more than writers: on an idle tick, post-join, the three passes and every job the tick used to run no longer run at all, which the idle test asserts, and recovery runs only while it has work (on an offline account it still does, read-only since #3262).

Tests

• idle_ticks_take_no_writer_and_spawn_no_housekeeping: no app or session writer outside the replay flush; no housekeeping batch, media sweep or upload promotion; no attachment or presentation pass; no post-join run; none of the jobs the tick used to run (backfill, promotion, compaction, KeyPackage catch-up, push, history dispatch); every watchdog_missed_wake_* counter at zero; recovery once per tick offline (Idle-cost regression since #3104: an inactive adapter repeats the runner replay flush and takes five writers per idle tick #3238).
• work_created_without_a_wake_is_counted_and_run_by_the_watchdog: an avatar request written straight to storage wakes nothing; the next tick's watchdog counts one missed wake and runs the pass.
• another_accounts_wake_runs_no_pass_here, an_account_wake_reaches_only_that_account.
• schedule::tests: a job re-arms 15 s after a run while owed and rests otherwise; a missed wake is owed work with nothing pending, logged once.
• compaction_rollbacks_are_spaced_1_min_then_10_min; a_rolled_back_compaction_is_tried_again_later now waits out the spacing.
• a_foreign_publication_in_its_own_slot_is_replaced and the sign-out withdrawal test assert the KeyPackage catch-up wakes.
• Storage: a_fresh_account_owes_no_pairing_or_push_timing, post_join_work_is_owed_only_while_a_fetch_or_catch_up_is_open, attachment_work_schedule_names_the_earliest_timed_candidate, avatar_work_schedule_is_the_earliest_acquisition_due, and chat_presentation_work_pending in the presentation backfill test.
• Mutations, each caught: an unconditional KeyPackage transaction (3 session writers over 3 ticks); wake_account waking every account; a job that never re-arms while owed (3 missed wakes over 3 ticks).

Verification

On 9acfeda (master at 0786bca), with CI's features:

• Every commit passes cargo fmt --check and cargo clippy -p marmot-app -p transport-nostr-adapter --all-targets -D warnings on its own; workspace clippy, the naming gate, the tracing audit and the test timing ratchet pass.
• nextest for marmot-app and transport-nostr-adapter: 3,492 of 3,492 passed.
• The idle test passed 15 of 15 rounds of the runtime and attachment tests run in parallel.
• Earlier on the first review's fixes: marmot-session and cgka-engine passing, relay_runtime (--test-threads 1) 192 of 192.

Summary by CodeRabbit

• Improvements
  • Background maintenance runs when work is due or an account-specific event occurs, rather than relying on a regular tick for every task.
  • Idle maintenance skips storage writes when there are no matching KeyPackages to remove.
  • Outstanding work is retried on a schedule, with periodic checks for missed work. Compaction retries are spaced out and stop after repeated failures.
  • Presentation updates wake only the affected account’s maintenance worker.
• Documentation
  • Updated release notes and runtime documentation to describe maintenance scheduling and storage behavior.

Walkthrough

The account worker now schedules maintenance from wakes and deadlines and checks for missed wakes. Presentation wakes can target individual accounts. SQLite adds work-state queries. Attachment compaction retries are spaced, and KeyPackage cleanup skips writes when no records match.

Merge Risk: Low · previous review 9c224

The change moves idle maintenance onto per-account wakes. Accounts with large legacy message history may run promotion batches back to back, which can contend with ingest writes. Two telemetry doc rows are also stale. Neither blocks merge, but both are worth fixing first.

Full details: Title check

Explanation

The title names the main change: idle maintenance jobs move from the shared 15-second tick onto per-account wakes and deadlines. The raw summary shows this through the new account-worker schedule module, per-account presentation wakes, and the watchdog. The title's reference to mdk#2923 step B fits the objectives, which describe the change as one step toward removing the tick. The title does not mention the compaction retry spacing or the new storage queries, but it does not need to cover every detail.

- Around line 1980-1982: Update the media-completion dispatch around
complete_media_http so HistoryDispatch is woken immediately only for settled
history completions or non-history completions. For an unsettled history
completion, preserve the retry backoff by scheduling dispatch at the established
retry deadline instead of waking it immediately; retain the existing completion
and deferral safeguards.

3538-3542: Trivial · Maintainability & Code Quality · Poor tradeoff

Synchronize the negative checks with worker progress.

A pass caused by Bob’s wake can start after the 200 yields. The negative assertion can then pass, and that pass can satisfy the later check for Alice’s wake. The watchdog test has the same fixed-yield gap.

Use a test checkpoint that acknowledges only after pending wakes and their due passes have been processed. Drain alone does not provide that ordering.

Replace the fixed-yield synchronization around the negative wake assertion with
a test checkpoint that acknowledges only after pending wakes and their due
passes have been processed; apply the same synchronization to the watchdog test.
Ensure the checkpoint orders the assertion after Bob’s wake work and cannot let
that pass satisfy the later Alice-wake check; `Drain` alone is insufficient.

- Around line 2921-2928: Update the LegacyPromotion scheduling match so a
Pending batch waits for the existing retry interval regardless of whether the
outcome is success or failure, instead of scheduling the next batch immediately.
Preserve the existing Complete and Halted behavior.

Review comments at @docs/marmot-architecture/runtime-latency-telemetry.md:
- Around line 87-88: Update the `worker_maintenance_housekeeping_batch` and
`worker_presentation_pass`, `worker_avatar_pass`, and `worker_attachment_pass`
descriptions to match the step B scheduling: describe housekeeping as its own
scheduled job, remove the maintenance tick as a pass trigger, and describe the
watchdog setting passes due only after a missed wake. Remove or correct the
claim that comparing pass counts with `worker_maintenance` shows how many passes
each tick sets off.
