Adds POST /api/dm/space-invite which fetches a space-invite snapshot
server-to-server from the space's home instance, ensures a 1-on-1 DM
between the caller and a friend, and posts a type='system' message
carrying SpaceInviteSystemPayload. Snapshot is never trusted from the
client. Rate-limited 30/60s per caller. Federation relay queued when the
recipient is on a remote instance (system message type forwarded by
Tasks 1-3).
Adds an `ensureOneOnOneDmChannel` helper that mirrors the dedup-or-create
behavior of the existing POST /api/dm handler — including federatedId
computation and the dm_channel_created notification payload — without
modifying that handler. Duplication is intentional; consolidation is a
separate follow-up.
Other namespaces use 'update' (users.update, spaces.update, channels.update,
roles.update); the new 'invites.patch' breaks the pattern. Renamed before
Tasks 17-19 import it. Plan updated to match.
The original test seeded the DB with the schema default (1) and asserted
the response was true after a partial PATCH. That passes both for
'untouched' and 'reset to default' — doesn't distinguish them. Now the
test toggles the DB column to false BEFORE the PATCH, then asserts the
false value survives both in the response AND in the DB row directly.
Surfaces the federatedRegistrationOpen flag (Task 1 schema column) on the
admin settings GET/PATCH endpoints and the public /api/instance/info
endpoint. Closes the 3 deferred TypeScript errors from Task 2 by
populating the now-required InstanceAdminSettings/InstanceInfoResponse
field.
Adds smoke tests (routes/instance.test.ts, routes/settings.test.ts) that
lock in the JSON contract the Connections UI (Task 21) and admin
RegistrationPanel (Task 15) consume, plus boolean-validation coverage
for the PATCH path. Updates docs/systems/admin.md with the new field in
both InstanceAdminSettings and the public info response schema.
Quality-review polish on Task 11:
1. One-line comment near the federatedRegistrationOpen default behavior
noting that the missing-row case is unreachable post-migration but
falls federation-closed defensively (asymmetric with registrationOpen
which falls back to env config — by design).
2. The "federated gate blocks token registration" test now sets ONLY
federatedRegistrationOpen=0, isolating the federated-gate-alone
effect rather than a both-gates-closed compound.
3. New test: open registration + revoked token → 201 (silently ignored).
Locks the spec §5.7 invariant "no validation when registration is open"
against future "let's just validate it for safety" regressions.
4. auth.md prose explicitly notes that federated stub upgrade and new-
account paths do NOT enter redeemInvite — surfacing the structural
enforcement of spec §1.3 "tokens never unlock federated creation".
The /api/auth/register handler now branches on homeInstance:
- Local path (no homeInstance): gated by registrationOpen. When closed, a
valid inviteToken bypasses the gate and is consumed atomically inside
redeemInvite()'s transaction (user insert + usedCount bump + redemption
row all commit together, or all roll back). When open, inviteToken is
silently ignored.
- Federated path (homeInstance set): gated by federatedRegistrationOpen.
Token is ignored entirely on this path -- tokens never unlock federated
creation. Closed → 403 with "Federated registration is closed".
InviteUnavailableError thrown by redeemInvite() (concurrent revoke,
last-slot race, expiry between check-invite and submit) is mapped to 403
"Invalid or expired invite". The in-txn re-derive closes the TOCTOU window.
9 new tests cover the toggle matrix from spec §5.6 + invite consumption
semantics + federated-gate independence + last-slot race rejection.
Updates docs/systems/auth.md: rewrites the Registration Gate section to
describe the three-path model (open / invite / federated), adds the toggle
matrix, adds an Invite Tokens subsection with the atomic-redemption shape,
notes that the federated stub upgrade is always gated by
federatedRegistrationOpen, never by an invite token.
Per quality review: replace per-property assertions with toEqual()
object-equality on the invalid-response bodies. Locks the enumeration-
shield contract — revoked/unknown/malformed/missing must all return the
SAME body, not just bodies that happen to satisfy individual assertions.
Quality-review polish on Task 8:
1. InviteUnavailableError gains a typed public readonly `reason` field
(the union 'not found' | 'revoked' | 'expired' | 'exhausted'). Task 11
route handler can switch on the discriminant to produce user-facing
copy without parsing the message string.
2. The original "aborts transaction if insertUser throws" test was
vacuous — the callback threw before any DB write, so SQLite ROLLBACK
never fired and the post-conditions were trivially true. Replaced
with two tests: one that explicitly validates the synchronous
short-circuit (no DB work happens at all), and a second that writes
a real users row inside the callback then throws AFTER the write,
proving the SQLite ROLLBACK actually reverts the in-callback write.
Quality-review polish: a one-line comment over the empty-updates guard
in reinstateInvite explains why removing it would re-leak a confusing
Drizzle error. A new test verifies that when Path A (revoked->active)
fails its post-state check, the original token is preserved by the
SQLite transaction rollback (not replaced by the would-be new token).
Inside patchInvite/revokeInvite txn bodies, all reads now go through
the tx proxy. Pre-Task-7 hygiene: locks in the consistent pattern that
reinstateInvite (Task 7) and redeemInvite (Task 8) will copy.
Createinvite test failures now pin to InviteValidationError, catching
regressions where the wrong error class would otherwise pass silently.
Both functions wrap their read-modify-write in a Drizzle better-sqlite3
db.transaction((tx) => ...) with in-txn re-fetch so concurrent admin
mutations are serialized by SQLite's writer lock.
- patchInvite: 404 on missing, 409 on revoked, 400 on maxUses < usedCount,
allows expiresAt to be moved into the past (effective soft-shut).
- revokeInvite: 404 on missing, 409 on already-revoked (explicit reject,
not silent no-op).
Also extracts foldUsername() to collapse the duplicated
(username, isDeleted) -> display string fold across resolveCreatorUsername,
listInvites, and listRedemptions (deferred refactor from Task 5 review).
Note: the plan's example used db.transaction(cb)() with an IIFE,
which is the raw better-sqlite3 signature. Drizzle's wrapper
returns the callback's return value directly, so we use the
(tx) => ... form consistent with the rest of the codebase
(userDeletion, federation, channels, etc.).
Tests: 36 invite-service tests pass (27 prior + 9 new).
Full server suite: 40 files / 311 tests pass.
Adds two query helpers to inviteService:
- listInvites(filter): single-query LEFT JOIN against users to surface
createdByUsername, with status filtered in TS via the canonical
inviteStatus() derivation. Avoids N+1 the spec calls out (§3.1).
'archived' = expired | exhausted | revoked. Sort: createdAt DESC.
- listRedemptions(inviteId): LEFT JOIN against users via userId to
expose currentUsername alongside the registrantUsername snapshot.
Three null-handling branches per spec §3.1: live (username),
tombstoned ('Deleted User', isDeleted=true), and hard-deleted
(userId null, currentUsername null, isDeleted false).
Sort: redeemedAt DESC.
Also fixes a mistitled DB-miss test in getInviteByToken: the original
'returns null when token not found' used a 24-char string that fails
the format regex *before* the DB lookup. Split into two tests covering
both the format-reject path and the well-formed-but-missing path.
40 files / 302 tests passing.
Storage panel's max-upload-size input now accepts any positive integer
(bounded only by JS safe-integer ceiling) and offers an MB/GB unit
toggle. Multipart limit relaxed to MAX_SAFE_INTEGER — actual cap is
enforced per-request from the DB setting, not at the framework layer.
