Removes `updatedAt` from the wire protocol and from every Local-prefixed
record type. Replaced by two orthogonal mechanisms — deriveUpdatedAt()
for read-side public-facing values, _updatedAtIndex shadow for indexed
sorts.
Local-side:
- New `_updatedAtIndex` shadow column. Stamped by the Dexie creating /
updating hook on every write. Stripped from the pending-change payload
so it never travels to mana-sync. Indexed in Dexie v53 on the 22 tables
that previously indexed `updatedAt`.
- `deriveUpdatedAt(record)` in sync.ts returns max(__fieldMeta[*].at) so
the public-facing Task / Note / etc. shape keeps an `updatedAt: string`
property without holding it as data.
- Type-converters across ~60 module/queries.ts and types.ts files now
call `deriveUpdatedAt(local)` instead of reading `local.updatedAt`.
Module-store sweep:
- Regex codemod removed `updatedAt: new Date().toISOString()` /
`: now` / `: now()` / `: nowIso()` stamping from 121 store files
(~382 call sites total). Single-property update calls
(`{ updatedAt: now }`) collapsed to `{}`; touch-only patterns
(writing/drafts, writing/generations) kept the call as a no-op
because the hook now stamps `_updatedAtIndex` automatically on
any Dexie modification.
- Local* interfaces stripped of `updatedAt: string` (43 types.ts files).
Public-facing types (Task, Note, Mission, Agent, …) keep
`updatedAt: string` as a computed read-side property.
- Companion's chat conversation now sorts on a real
`lastMessageAt` data field instead of touching `updatedAt`.
- Session-only stores (times/session-alarms, session-countdown-timers)
stamp `updatedAt: now` directly because they're not in Dexie and
have no field-meta layer to derive from.
Sync engine:
- applyServerChanges sets `_updatedAtIndex` itself when applying
server changes (max of server-field times for updates, recordTime
for inserts) so server-replays land orderable.
- Dropped the legacy `localUpdatedAt` fallback — every record now has
`__fieldMeta`, the per-field at is the canonical source.
- Soft-delete tombstone path stops stamping `updatedAt: serverTime`,
uses `_updatedAtIndex` instead.
Server-side:
- mana-ai iteration-writer no longer emits `updatedAt` in
sync_changes.data; receivers derive it from the field-meta map.
- mana-sync types: no change (the wire format already uses
`field_meta` / `at` from F1).
Out of scope: backend Drizzle schemas (mana-credits, mana-events, …)
keep their `updated_at` columns. Those are pure server-internal — not
part of the sync_changes / __fieldMeta mechanism F3 cleans up.
Tests + checks:
- 0 svelte-check errors over 7652 files.
- 29/29 sync.test.ts (vitest).
- 61 mana-ai bun tests.
- mana-sync go test ./... cached green.
Plan: docs/plans/sync-field-meta-overhaul.md F3.
