Remove superseded events automatically. New databases shrink in background batches; existing databases can enable this with t3 doctor --fix. Reconnects fall back to snapshots after history cleanup.

CommandBehavior
t3 doctorChoose repairs; recommended set preselected
t3 doctor --dry-runPreview repairs; overrides --fix
t3 doctor --fixApply recommended repairs without prompting

Web/desktop Storage settings and mobile Maintenance show a dismissible notice when an older database has at least 1 GiB to reclaim. The copied command includes that environment's data directory. The CLI shows a stage bar and elapsed time during repairs. Doctor restores a service it paused even after repair failure/cancellation, leaves already-stopped and other environments' services alone, and documents the workflow in a dedicated user guide. Desktop/manual servers must be closed first.

Measured on a copy of the maintainer's database

Delete 898,925 obsolete events6 min 12 s
VACUUM + checkpoint4 min 6 s

Deletion alone reduced the full-history scan to 2.08 s; VACUUM reduced it further to 1.01 s. Automatic deletion starts after one minute and repeats every six hours, in 50-row batches. Full VACUUM is explicit and offline. Converted/new databases reclaim up to 1,024 pages per minute while running.

Method: Node 24.21.0 / SQLite 3.53.4, Apple M4 Max, 64 GB RAM. Medians of 3 scan/ANALYZE runs, 5 count runs, and 11 recent-range runs. Cache state was not controlled. Full-history scanning is a diagnostic upper bound; normal reconnects are capped. The same recent range returned 1,000 rows before and 331 after deletion. Startup optimize took 7.4 ms before and 1.2 ms after; the original 30-second delay was not reproduced.

Limitation: The guarded CLI refused one pre-existing unreadable thread projection. Benchmarks therefore invoked the underlying compactor and VACUUM directly on the disposable copy. The live database was untouched.

Validation: original 146 focused tests; 45 focused tests for doctor, database maintenance, storage status, scheduling, authorization and instrumentation. Server/web/mobile typechecks and targeted lint pass. 77 focused CLI/service/database tests cover selection, automatic service handling, dry-run isolation and progress. Isolated CLI dry run confirmed while the server was running.

UI verification is pending: the built-in browser timed out twice on snapshots. No screenshots are claimed.

Implemented with GPT-6.1 Sol via Codex.

Approvability

Verdict: Not approved

Macroscope's review found this PR not approvable — This XL PR adds default background database compaction/reclamation, an offline repair CLI, cross-client replay changes, and service lifecycle handling rather than making a small isolated fix. It also touches an auth package, suppresses a static-analysis diagnostic, and has an unresolved high-severity concern about services remaining stopped after restart failure.

Not approved because:

📝 Walkthrough

This change adds database inspection, space reclamation, and event-history compaction. It adds a t3 doctor command and settings notices for database maintenance. Pull-request link synchronization now emits link-specific events, and replay uses snapshots when event history has been compacted.

Changes: Database Storage and Event History Maintenance

Layer / File(s)Summary
Inspect and reclaim database space
apps/server/src/persistence/DatabaseStorage.ts, apps/server/src/persistence/Sqlite.ts, packages/shared/src/databaseStorage.ts, packages/contracts/src/settings.ts		Adds database size and reclaimable-space reporting, incremental page reclamation, and the compaction recommendation predicate. New databases enable incremental auto-vacuum.
Emit and apply pull-request link updates
packages/contracts/src/orchestrationV2.ts, packages/shared/src/threadPullRequests.ts, apps/server/src/orchestration-v2/Orchestrator.ts, apps/server/src/orchestration-v2/ProjectionStore.ts, apps/server/src/orchestration-v2/PullRequestSyncReactor.ts, apps/server/src/orchestration-v2/ThreadSettlementService.ts, apps/server/src/relay/AgentAwarenessRelay.ts, packages/client-runtime/src/state/orchestrationV2Projection.ts		Pull-request link and watch sync commands emit link-specific events. Server and client projections update the matching link while retaining other links. Event consumers handle the new event type. Tests cover projection rebuild and compaction.
Compact superseded events and record watermark
apps/server/src/orchestration-v2/ProjectionMaintenance.ts, apps/server/src/persistence/OrchestrationEventStore.ts, apps/server/src/ws.ts		Compaction uses smaller pages, removes superseded link-update events, and records a compaction watermark. Replay statistics report compacted ranges, which trigger snapshot fallback.
Run scheduled storage reclamation and event compaction
apps/server/src/orchestration-v2/EventCompaction.ts, apps/server/src/server.ts, apps/server/src/orchestration-v2/EventCompaction.test.ts		The runtime starts storage reclamation after one minute and repeats it every minute. It starts event compaction after one minute and repeats it every six hours.
Inspect and compact databases with t3 doctor
apps/server/src/persistence/DatabaseMaintenance.ts, apps/server/src/cli/doctor.ts, apps/server/src/cli/doctorProgress.ts, apps/server/src/cloud/bootService.ts, apps/server/src/binCli.ts, docs/user/doctor.md		Adds database inspection and compaction, repair selection, dry-run and fix modes, progress output, and service stop-and-restore behavior. Tests cover maintenance, CLI behavior, and service restoration.
Deliver storage status and display notices
packages/contracts/src/rpc.ts, apps/server/src/ws.ts, packages/client-runtime/src/state/server.ts, apps/web/src/components/settings/*, apps/mobile/src/features/settings/*		Adds a database-storage status RPC and environment capability. Web and mobile settings show compaction notices for eligible environments and store dismissals.

Separate service construction from its layer. This module constructs DatabaseStorage inside Layer.effect instead of defining a private make before layer. Extract the construction effect so the module follows the required service shape. As per coding guidelines, “One module per service, in this order: imports, errors and schemas, the Context.Service tag with its interface inline, make, then layer.” As per path instructions, “Follow the prescribed service-module structure and import conventions.”

🌐 Web query:

Effect acquireUseRelease release behavior when acquisition fails or is interrupted official documentation

💡 Result:

1**Short answer:** `release` runs only if `acquire` successfully produces a resource.
2
3- **Acquisition fails:** There is no acquired resource to pass to `release`, so it is not run. The acquisition failure propagates.
4- **Interrupted during acquisition:** Effect’s resource-management docs say acquisition is **uninterruptible**. So interruption is deferred until acquisition completes; if it succeeds, the resource is released as the interrupted operation exits. This follows from the documented acquisition guarantee, rather than an explicit `acquireUseRelease` interruption example. ([effect.website](https://effect.website/docs/v4/resource-management/scope))
5- **Use fails or is interrupted:** Once acquisition succeeds, `acquireUseRelease` releases the resource even if using it errors; Effect’s finalization documentation also says cleanup runs on interruption. ([effect.website](https://effect.website/docs/v4/resource-management/introduction))
6
7The official `acquireUseRelease` page states the success/use/release pattern, but doesn’t spell out acquisition-failure behavior separately. ([effect.website](https://effect.website/docs/v4/resource-management/introduction))

systemctl stop timeout service already stopped systemd official documentation launchctl bootout --wait timeout official documentation

💡 Result:

1If you’re comparing “stop this service and wait until it’s stopped” across systemd and macOS:
2
3- **systemd:** `systemctl stop name.service` waits for the stop job by default; `--no-block` enqueues it and returns without waiting. The service’s `TimeoutStopSec=` controls how long systemd waits during shutdown before taking the configured timeout action. If the unit is already inactive, systemd defines that state as stopped; the docs don’t promise a special message or exit status specifically for stopping an already-stopped unit. ([man7.org](https://man7.org/linux/man-pages/man1/systemctl.1.html?utm_source=openai))
4- **macOS `launchctl`:** `bootout` removes a service or domain from launchd. The cited `launchctl` manual describes its target forms, but does **not** document a `--wait` option or a timeout for `bootout`. So `launchctl bootout --wait ...` isn’t established by this source as supported syntax. ([keith.github.io](https://keith.github.io/xcode-man-pages/launchctl.1.html?utm_source=openai))
5
6The `launchctl` source is an Xcode man-page mirror, not Apple’s official documentation; its page identifies an Xcode 27.2 beta 2 manual set. I couldn’t verify the behavior against an Apple-hosted manual. ([keith.github.io](https://keith.github.io/xcode-man-pages/?utm_source=openai))

Restore the service when stopping fails.

withStopped uses the stop steps as the acquisition of Effect.acquireUseRelease. A stop command timeout or non-zero exit fails acquisition, so activate does not run. A stop command can fail after it has started changing the service state, which can leave the service down or partially transitioned.

The interruption claim is not applicable here because Effect acquisition is uninterruptible. The fix should still cover stop failures:

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Make the copied command usable in Windows Command Prompt. On win32, Line 26 still surrounds baseDir with single quotes. If the path contains spaces, cmd.exe splits the argument, so the copied t3 doctor command cannot select that database. Generate a Command Prompt-safe command or label the command as PowerShell-only.

Enable incremental vacuum for migrated V2 databases.

layerConfig calls initializeV2Database(dbPath) before layerFromPath(dbPath). When a legacy state.sqlite exists, the initializer copies its tables into the V2 destination. The later empty-schema check then skips PRAGMA auto_vacuum = INCREMENTAL, so the migrated database does not receive scheduled page reclamation. Handle the auto-vacuum mode before copying the schema, or explicitly convert the copied database with VACUUM.

Rebuilt as a stack. This PR found the real problem and the shape of the fix: superseded whole-payload events dominate the database, and existing databases need an offline VACUUM to switch to incremental auto-vacuum. The measurements here made the case.

It mixed three separable concerns, so it is replaced by:

  • #19435 — background compaction, incremental auto-vacuum for new databases, online reclaim
  • #19436 — t3 doctor offline compaction + VACUUM, pausing and restoring this home's background service
  • #19437 — server.getDatabaseStorage and the web/desktop Storage and mobile Maintenance notice

I compared the original diff against the stack. Changes from the original:

  • Replay boundary dropped. The global event-compaction marker sent a full snapshot to every client reconnecting with an older cursor. Compaction now keeps each message, node and PR link's oldest and newest event, which keeps replays correct and in order without it. thread.deleted is no longer compacted, and visit/mark-unread events supersede only each other.
  • withStopped reworked. It no longer turns a restart failure into a defect. It restores the service after a failed stop, stops crash-looping or throttled services too, and doesn't enable a disabled service.
  • Doctor simplified. Detection is the exclusive SQLite lock instead of the pid file, it uses the configured database path, and output is plain Console instead of the ANSI progress module.
  • Copied command fixed. It uses the desktop CLI launcher when t3 isn't on PATH, and PowerShell quoting on Windows.
  • Small leftovers. A retried MCP metadata update falls back after compaction. Docs moved into the background service guide. The recommendation helper moved into contracts.
  • Tests: roughly 27 test cases became 6 new tests plus 3 extended ones.

Nothing from the original was dropped without a replacement, apart from the stage progress bar.
