Fixes all 109 golangci-lint findings (106 contextcheck, 1 gocritic,
2 gosec) that accumulated after D2 wired dbgen (whose queries take ctx)
under ctx-less db.DB wrappers while CI lint was quota-dead. No nolint
comments added; every finding fixed by genuinely threading context.
- db: all 138 hand-written db.DB methods take ctx first; the dbCtx()
Background shim is deleted; raw Query/QueryRow/Exec/Begin use their
Context variants; the four redundant ctx-less passthroughs removed.
db.Auditor/WriteAudit gain ctx.
- Seams: permissions.Checker (DB iface, HasChannelPerm,
RequireChannelAccess) and the service.Store interface mirror the new
signatures (ws.EventStore and plugin.PluginStore already did).
- Callers: api/admin handlers use r.Context(); ws per-message paths use
the connection ctx via DispatchV2; hub loops and startup wiring use
context.Background(); service methods thread ctx where they have one
and Background where no ctx exists. Public service surface reached by
ctx-holding chains (PermissionService.HasChannelPerm/GetRoleForUser/
RequireChannelAccess, message/dm/block/invite/profile methods) is now
ctx-first.
- Detached (context.WithoutCancel) where cancellation would break an
invariant, found by a 3-lens adversarial review of the diff:
* voice-leave background retries (a dead webhook/connection ctx killed
retry 2 before it ran, leaving ghost capacity-holding voice rows)
* rollbackVoiceJoin's compensating delete (its trigger IS the cancel)
* post-2FA-change DeleteOtherSessions and logout DeleteSession (the
security tail of a committed change must not die with the request)
* all api/ws audit writes (a banned user could suppress their own
login_blocked_banned row by aborting the request mid-bcrypt)
* admin backup VACUUM INTO (an interrupt left a truncated .db that
the backup list presented as restorable)
* post-commit message/edit refetches (a committed message must still
fan out when the sender disconnects)
* hub settings-cache refresh (one dead connection could pin stale
values for the 30s TTL)
- gocritic rangeValCopy fixed (index iteration); gosec G306 excluded in
config with justification (generated source must stay world-readable)
instead of flipping genprotocol output to 0o600.
Verified: gofmt/vet, all four build-tag variants, full suite, deadlock
pass, full -race pass, golangci-lint 0 issues uncapped.

Protocol codegen (decision D4, audit A-2026-07-08):
- Add docs/protocol-schema.json as the real single source of truth for
WS message-type constants, making the long-standing 'generated from'
comment in both constant files true.
- Add Server/scripts/genprotocol, a generator emitting both
Server/ws/message_types.go and Client .../lib/protocolTypes.ts
(constants byte-for-byte value-identical to before; only headers,
ordering alignment, and provenance comments changed).
- Add make protocol-generate / protocol-verify and wire protocol-verify
into CI next to sqlc-verify.
Quick wins (decision D8):
- admin: log LogAudit write failures in the backup handlers instead of
discarding them (prior audit #10).
- api: fix self-contradictory upload Cache-Control to 'private,
no-cache' per remediation plan W3-4; drop the now-unused
fileCacheMaxAgeSeconds constant; update test.
- ws: route the hub settings cache through db.GetSetting instead of
inline SQL.
- ws: fix a latent data race — main.go wires SetEventPersister and
SetEventStore after NewRouter has already started the hub Run loop,
which reads those fields on the broadcast/replay paths. They (and
pluginSink, which one test sets post-Run) are now atomic pointers;
the remaining pre-Run-only setters reject late calls with an error
log instead of racing silently.
Update the audit closure table and decisions doc statuses accordingly.

Install and configure mutation testing (Stryker for client, go-gremlins
for server), load testing (k6), chaos testing (toxiproxy), WAF middleware
(Coraza with OWASP rules, opt-in via waf_enabled config), and Zod for
runtime schema validation. All tools verified building cleanly.
