Server boundaries — database-call and lifecycle inventory

Written: 2026-08-29 (B3-0), measured at dev ad4defc2. Re-measured: 2026-08-30 (B3-2) — the first table and the auth slice's after-state at fe1d11b8 (pre-squash; the squash SHA is in the plan's B3-2 evidence block); 2026-08-30 (B3-3) — the first table again, and the hub lifecycle section's after-state rows, on feat/b3-3-lifecycle. Owner: the B3 plan, plans/b3-server-architecture-guardrails-2026-08-29.md. Regenerate the first table: cd Server && go run ./cmd/dbinventory and paste its output between the markers below. The tool exits non-zero when a file imports db without a row, or a row names a file that no longer imports it — the same two failures go test ./invariants/ reports.

This is the inventory the roadmap's B3 entry gate asks for ("hotspots and direct database call sites have an owned inventory") and the evidence its exit gate consumes ("every direct database use above the domain layer is justified or removed"). It answers three questions for every production Go file above the domain layer: does it import db; what does it use db for; and what happens to that use — one of four dispositions from the layout-refactor supplement:

Disposition	Meaning	Rows
move	persistence or a domain decision that belongs behind a service; Family names the service B3-8 (or B3-2) builds	26
adapter	a transport adapter that uses db types or pure helpers only — response shapes, status helpers — no persistence call	17
boundary	an explicit composition or transaction boundary that legitimately owns a handle (process entry, CLIs, health probe)	12
remove	the import is unnecessary and goes	0

The rows live in code, not only here: Server/invariants/db_import_boundary.go holds them as DBImportAllow, the db-import-boundary rule fails any new importer that has no row, and TestDBImportAllowIsLive fails any row whose file stopped importing db. The list only shrinks — B3-2 deleted the two auth handler rows (28 → 26 move), B3-8 deletes a family's rows as it moves.

How the measurement works

Server/cmd/dbinventory is syntactic (go/parser + go/ast, no type information), like the invariants package. It records three things per file:

• db.* types — selectors that db declares as types (db.User, db.Channel, …). A file whose only use is types is type-only: it shapes data, it does not persist.
• db.* funcs and sentinels — package-level functions (db.WriteAudit(), db.Open()) and values (db.ErrNotFound). Pure helpers such as db.StatusForViewer() and db.BroadcastStatus() land here too; they are computations over already-loaded rows, not queries.
• *db.DB method calls — calls whose receiver is an identifier declared *db.DB in the file (parameter, result, var, or assigned from db.Open*), or a selector whose final field is declared *db.DB anywhere in the same package (h.db.X, s.deps.DB.X). This is the persistence surface the dispositions are about.

A shape the walker cannot see (a *db.DB reaching a file through an untyped interface, say) would show up as a row with an import and nothing recorded — which is a row worth reading, and none exists today.

56 files import db outside db/ and service/ (. 1, admin 16, api 10, auth 2, cmd/gendocs 1, cmd/seed 2, internal/app 6, plugin 1, ws 17); 17 are type-only; 0 unlisted. Dispositions: adapter 17, boundary 13, move 26. Move targets: auth 7, channel 6, connection 1, role 1, settings-ops 4, upload 2, user 2, voice 3.

Reading the table:

• Type-only files (14) need no service; they stay adapter. The db types they use are the wire and response shapes. Whether those types should live outside db is a B3-8 question per family, not a boundary violation.
• ws/serve_ready.go (45 references, 7 distinct queries) is the single heaviest reader: the ready snapshot reads channels, overrides, unreads, DM channels, members, roles and voice states in one place. B3-5 keeps it as the "fresh-connect initialisation" file and B3-8's channel family gives it a snapshot service.
• Two raw SQL escapes exist above the domain layer: api/upload_handler.go (QueryRowContext) and admin/handlers_backup.go (SQLDb for VACUUM INTO). Both are move; the backup one may end as an explicit boundary once settings-ops owns backups — the row is decided when that family moves, not now.
• Duplicated persistence is visible in the families: API-token CRUD in admin/handlers_tokens.go and token_cli.go; owner-role reads in admin/middleware.go (OC-0345) and api/middleware.go; voice state in ws/hub_sweep.go, voice_join.go, voice_moderation.go. One service per family removes each duplicate.
• ws/serve.go is the one connection row: it is not a domain family but the connect/disconnect lifecycle that touches four of them. B3-5 splits it by responsibility first; the pieces then join their families' rows.

Hub lifecycle inventory

Input to B3-3 (internal/app/) and B3-4 (constructor options). The before-state was measured at ad4defc2; the after-state rows are B3-3's, on feat/b3-3-lifecycle, and are what B3-4 starts from.

Construction and setters (S-11) — before B3-3

ws.NewHub(database, limiter, svc) was called once, inside api.NewRouter (Server/api/router.go:106) — not in main.go. The seven post-construction setters and where they were called:

Setter	Declared	Called from	Required before Run?
SetPluginRegistry	ws/hub_events.go:60	api/router.go:325	only when plugins are enabled — optional collaborator
SetPluginEventSink	ws/hub_events.go:70	api/router.go:328	same
SetLiveKit	ws/hub_livekit.go:10	api/router.go:342	yes for voice: every voice join needs the token signer; nil means voice silently fails
SetLiveKitProcess	ws/hub_livekit.go:48	api/router.go:360	only when the supervised LiveKit process is configured
SetEventPersister	ws/hub_events.go:40	main.go:453	yes when persistence is on: events emitted before it is set are not persisted
SetEventStore	ws/hub_events.go:48	main.go:454	yes for replay: resume without a store answers a full ready
SetPendingVoiceModFlags	ws/voice_moderation.go:599	voice moderation paths at runtime	no — genuinely replaceable runtime state; stays a setter

Two owners (the router and main.go) set collaborators on one hub, and the hub started (hub.Run, ws/hub.go:273) with no check that the required ones were present.

Construction and setters (S-11) — after B3-3

ws.NewHub is called from app.StartRuntime (Server/internal/app/hub.go), which also applies every setter that must land before hub.Run and then starts the dispatch goroutine. api.NewRouter takes the built hub as part of api.Runtime and returns only the handler and its cleanup.

Setter	Called from (before)	Called from (after)	Still required before Run?
SetPluginRegistry	api/router.go:325	internal/app/hub.go (wirePlugins)	optional
SetPluginEventSink	api/router.go:328	internal/app/hub.go (wirePlugins)	optional
SetLiveKit	api/router.go:342	internal/app/hub.go (startVoice)	yes for voice
SetLiveKitProcess	api/router.go:360	internal/app/hub.go (startVoice)	when supervised
SetEventPersister	main.go:453	internal/app/persistence.go (startEventPersister)	yes when persistence is on
SetEventStore	main.go:454	internal/app/persistence.go (startEventPersister)	yes for replay
SetPendingVoiceModFlags	voice moderation paths at runtime	unchanged	no

One owner: every row is now inside internal/app. Two of them are still in a second file — the persister and the store are set where the persister is built, one lifecycle stage after the hub, because both setters are explicitly safe to call after Run has started (ws/hub_events.go) and moving them earlier would reorder the boot. B3-4 is what collapses them into validated HubOptions at the single construction point; the router is no longer one of the places that has to change for it.

Locks

Five locks on Hub, all syncutil (so the -tags deadlock pass sees them):

Lock	Declared	Guards (from the field comment)
mu	ws/hub.go:25	the client registry and subscriptions
seqMu	ws/hub.go:58	seq assignment + replay insertion + delivery order, serialised together
settingsMu	ws/hub.go:122	the cached server settings
keyHolderMu	ws/hub.go:130	the voice E2EE key-holder map
presenceMu	ws/hub.go:135	presence coalescing state

The lock order is not written down anywhere — not in Server/CLAUDE.md, docs/architecture/websocket.md, or hub.go. It is proven only by the -tags deadlock -count=10 ./ws/ pass. B3-5 records the order in hub.go's package comment before it moves a single function, so every pure-move commit has something to be checked against.

Start, drain, stop — before B3-3 (main.go run, main.go:107)

Start order, then the defer stack that undid it (LIFO — the last started was the first stopped):

#	Start (main.go)	Stop (defer, in registration order — ran in reverse)
1	background context	bgCancel() :118
2	runOpenDatabase → db.OpenWithMaxReaders :314-322	database.Close() :148
3	runInitDatabase → db.Migrate :333-347	—
4	runInitTelemetry :369	telemetryStop() :156
5	runInitPlugins :392	runClosePlugins :161
6	api.NewRouter → hub built here :164	routerCleanup() :165, then hub.GracefulStop() :172
7	runStartEventPersistence :435 (sets persister/store)	runStopEventPersistence :176
8	runStartAuditWriter :488	runStopAuditWriter :186
9	runStartACME :505	via runShutdownServers :667
10	runStartMaintenance :527	maintenanceStop() :207
11	signal.NotifyContext :214	stop() :215
12	runServeAndWait :629 → runShutdownServers :667	srv.Shutdown, acmeSrv.Shutdown, hub drain

Three facts B3-3's composite close had to preserve, each already encoded in a comment at the cited line: the audit writer's stop is registered after database.Close so it flushes before the handle goes (:183-186); event persistence stops before the LIFO-later database.Close so no prune is still running (:476); hub.GracefulStop must run even on an early return so the supervised LiveKit process is not orphaned (:168-172). Any early return err between steps 2 and 12 relied on this defer stack — there was no single close function, which is exactly what B3-3's failure-injection test now pins.

Start, drain, stop — after B3-3 (App.stages() / App.Close)

Server/internal/app/lifecycle.go declares the start sequence as a list, and App.Close walks the close step each stage registered in the reverse of that order. There is no defer stack and no second teardown path: App.Run closes on every return — a failed start, a serve error and a clean shutdown alike.

#	Stage (App.stages())	Close step, and what it does
1	(in Run) bgCtx	background-context — cancels bgCtx; registered first, so it runs last
2	data-dir	—
3	tls	—
4	database	database — database.Close(), registered before the migration runs
5	migrate	—
6	telemetry	telemetry — bounded OTel shutdown
7	plugins	plugins — registry.Close
8	hub	hub — GracefulStopContext, the only caller of LiveKitProcess.Stop
9	router	router — the rate-limiter cleanup goroutine
10	event-persistence	event-persistence — drains the persister, cancels bgCtx, joins the pruner
11	audit-writer	audit-writer — drains the audit queue
12	maintenance	maintenance — joins the maintenance loop
13	acme	— (shut down by the http step, in the order the drain requires)
14	http	http — ACME shutdown, then in-flight handlers, then the hub, on one 30s budget
15	signals	signals — unregisters the signal handler; registered last, so it runs first

Close order is therefore signals, http, maintenance, audit-writer, event-persistence, router, hub, plugins, telemetry, database, background-context. All three facts hold, and now hold because of the ordering rule rather than because of where a defer happened to sit:

• the audit writer and event persistence both start after the database opens, so both stop before database.Close;
• the http step runs first, so in-flight handlers drain while the hub and the event persister are still live — which is why ACME and the HTTP server start one stage after the maintenance loop rather than before it;
• the hub step is reached on every return from Run, so a supervised livekit-server process is never orphaned (OC-0027).

App.Close reports the first error and still runs every later step: the steps below a failing one are the ones that release the database handle, the LiveKit process and the audit queue. internal/app/close_test.go pins the order, the first-error rule and idempotence; internal/app/lifecycle_failure_test.go fails each stage in turn — the table is generated from App.stages(), so a new stage is covered the day it is added — and asserts on every row that the error names the stage, no goroutine is left running, the database handle is closed and the listener is not left bound.

Auth slice — before-state dependency graph

The three files B3-2 moves, and what they depend on at ad4defc2. The after-state table follows it.

File	Imports (module-internal)	db symbols used
api/auth_handler.go	auth, db, permissions, service	types DB, Session, User; funcs WriteAudit, IsUniqueConstraintError; sentinels ErrLastAdmin, ErrNotFound; methods CreateSession, CreateUserWithInvite, DeleteAccount, DeleteSession, GetSetting, GetUserByID, GetUserByUsername, UpdateUserCustomStatus
api/totp_handler.go	auth, db	types DB, Session, User; func WriteAudit; methods DeleteOtherSessions, GetUserByID, UpdateUserTOTPSecret
auth/*.go (10 files)	db (types only, in helpers.go, resolve.go), config, syncutil	types User, Session, APIToken, Role — no method calls; auth is a leaf that computes and does not persist

Eleven distinct *db.DB methods across the two handlers (ten after de-duplicating GetUserByID). That was the upper bound set for the interface api/auth_deps.go declares in B3-2.

Auth slice — after-state dependency graph

Measured at fe1d11b8 (B3-2, pre-squash). The handlers import db nowhere; api goes from 12 db importers to 10.

File	Imports (module-internal)	db symbols used
api/auth_deps.go	service	none — nine-method AuthService interface naming service.Principal, RegisterInput, LoginInput, AuthResult, TOTPChangeResult
api/auth_handler.go	auth, service	none — auth for ValidateUsername/ValidatePasswordStrength; service for the interface's types, the Err* categories writeAuthError switches on, and SanitizeText (imported before B3-2 too)
api/totp_handler.go	auth, service	none — auth for ExtractBearerToken; service for TOTPChangeResult and the Err* categories
api/middleware.go	auth, db, permissions, service (new)	unchanged row (move, auth): gained principal(r), which reads the *db.User/*db.Session it already stores on the context and hands them to the handlers as service.Principal
api/profile_handler.go	unchanged	unchanged row (move, upload): now hosts userResponse/toUserResponse, the one converter that names db.User, which /me and the auth responses share with PATCH /users/me
service/auth.go	auth, db, permissions	funcs WriteAudit, IsUniqueConstraintError; sentinels ErrLastAdmin, ErrNotFound; the ten methods, through service.Store: CreateSession, CreateUserWithInvite, DeleteAccount, DeleteOtherSessions, DeleteSession, GetSetting, GetUserByID, GetUserByUsername, UpdateUserCustomStatus, UpdateUserTOTPSecret
auth/ratescale.go	—	none — the auth rate multiplier, moved from api/constants.go so the route mounts and the service's login accounting read one value

Honest reading of the plan's target ("handlers importing neither db nor service directly"): met for db, not for service. Both handlers import service because the consumer-owned interface is expressed in the service's input and result types and its Err* values — the alternative, an api-side copy of every type, would have been a second definition of the same shapes. The dependency direction is still api → service → db; what the handlers no longer see is the database.

Client baselines are not here

The supplement's Phase 1 item 5 (client native-import, Rust-command, import-cycle, timer/listener, bundle, coverage and mutation baselines) is B7's entry work, recorded there. Nothing under Client/ was measured for this document.
