Closes the gap between "invite flow UI exists" and "two users in the
same space actually see each other's data". Three pieces land together
because they're meaningless without each other.
mana-auth — new internal endpoint:
GET /api/v1/internal/users/:userId/memberships
Returns [{organizationId, role}, ...] for the user. mana-sync uses
this to populate the multi-member RLS session config.
mana-sync — membership lookup:
new internal/memberships package with an HTTP client + 5 min
per-user cache, fail-open (empty list = pre-Spaces behavior).
Config gets MANA_AUTH_URL (default http://localhost:3001).
Handler.NewHandler takes the Lookup. Every Push/Pull/Stream call
now passes spaceIDsFor(userID) to Store methods.
GetChangesSince + GetAllChangesSince extend their WHERE clause:
WHERE (user_id = $1 OR space_id = ANY($memberSpaces))
so co-members see each other's rows, not just the author.
apps/web — encryption skip for shared-space records:
encryptRecord now checks record.spaceId:
- `_personal:<userId>` sentinel OR no active shared space → encrypt
with user master key (E2E as today).
- Active space resolves to non-personal type AND spaceId matches
that space → skip encryption; write lands plaintext.
decryptRecord is unchanged because its per-field isEncrypted() guard
already passes plaintext through.
Phase-1 compromise: shared-space data is protected by server RLS
only, not E2E. Phase 2 adds per-Space shared keys with per-member
wrap — tracked in docs/plans/spaces-foundation.md.
Plus docs/plans/shared-space-smoketest.md: step-by-step Zwei-User-Test
mit erwarteten Ergebnissen und Debugging-Hinweisen bei Problemen.
Build + go test + web check all green.
