Rides the existing `<@id>` token: `everyone` already matches the parser's
`[a-zA-Z0-9_-]+`, so the markdown pre-processor, the inline renderer and the
badge pick it up with no second syntax. User ids are snowflakes, so the
literal `everyone` cannot collide with one.
Gated on a new MENTION_EVERYONE permission rather than being open to all —
otherwise a role can never take it away. Granted to @everyone by default: on
a small instance the ping is a convenience, not a weapon, and an owner who
disagrees can deny it and grant it to a role instead.
Two things that would each have made the gate a no-op:
- DEFAULT_EVERYONE_PERMISSIONS only applies at space creation, so spaces
that predate the bit would have had every @everyone mention silently
stripped. A boot-time backfill ORs the bit into @everyone roles only
(`id = space_id`), leaving other roles alone so a later denial is not
overruled on the next restart. Verified against a copy of the production
database: three roles moved by exactly 2^15, non-@everyone roles
untouched, second pass a no-op.
- Enforcement covers edit as well as create; without that, posting a plain
message and editing it is the way around the permission.
A message that lacks the permission is not rejected — losing what someone
wrote over one token is worse than posting it. The token is demoted to the
literal `@everyone` text they typed: the message reads the same and rings
nobody.
Code spans and fences never ping. People paste payloads and snippets into
chat, and a paste should not ring everyone's client. The same rule decides
the row highlight and the notification sound, so the three cannot disagree.
Verified: web build, server typecheck, 504 web tests, 804 server tests.

Records who changed what, and is the mechanism statistics will read — one
event table rather than two logs that drift apart.
The table is deliberately generic (action + target + JSON metadata) so a new
action needs no migration. Writes never throw: a kick must not fail because
its log entry could not be written, since the kick already happened.
Leaving is recorded as a different action from being removed. The same route
serves both, and a log that conflates them misleads exactly when it matters.
Actor is nullable with ON DELETE SET NULL: the event outlives the account, and
a log that vanished with its actor would be worthless. Reads are gated on
MANAGE_SPACE rather than a new permission bit, which would default to nobody
until every role was re-edited. Paging uses the snowflake id, stable even for
two events in the same millisecond, and an action this build does not know
still renders a row.
- Add Activity, ActivityType, ActivityTimestamps, ActivityAssets types to shared types
- Add activity_update client event and activities field on presence_update server event
- Add userActivities to ready payload and showActivity to User/UpdateUserRequest
- Create shared activities.ts with ACTIVITY_LIMITS, ACTIVITY_PRIORITY, getPrimaryActivity
- Add show_activity column to users table (schema + migration)
- Update sanitizeUser with isSelf parameter; only include showActivity for self
- Fix .map(sanitizeUser) calls to use arrow wrapper to prevent index-as-boolean bug
- Mark auth routes (register/login) as isSelf=true since they return own user data
- Add Backspace-design-prototype.html: finalized "Aether Drift" design
language with warm matte surfaces and subtle frosted glass accents
- Update CLAUDE.md with DESIGN SYSTEM section and remove Discord clone references
- Rename all Opencord references to Backspace across the full codebase
- Archive outdated design experiments and Discord-specific assets
- Add science-backed accessibility fallback (prefers-reduced-transparency)
Replace string-based role checks (role === 'admin') with a bitwise BigInt
permission system. Adds computePermissions() resolution engine following
Discord's model: @everyone base → role union → admin shortcut → channel
overrides (role deny/allow → member deny/allow). Ready payload now filters
channels by VIEW_CHANNEL and attaches per-user myPermissions to each
server and channel. Includes channel_overrides table, @everyone role
auto-creation, migration for existing servers, and override CRUD API.
