A consultant could search two letters of their own name, open the row, send a message, and lose the thread on refresh. Four symptoms, two defects, and neither of them is "you can talk to yourself".

What was actually wrong

The label. search-appointments is correctly scoped — the caller must be the consultee or the consultant on every row it returns — but it labelled every row consultantName. On a consultee's dashboard that names the other party; on a consultant's it names the viewer. The channelId underneath was always right. ChannelSearch then grouped rows by that display name, which is how one person's consultation and subscription collapsed into a single row subtitled "Consultation & Subscription".

The phantom channel. ChannelSearch opened a result with client.channel(type, id).watch() on a browser-computed id. In stream-chat, watch() posts to the channel query endpoint — the same endpoint create() posts to; channel.create() is literally query({ created_by_id }). So watching an id that does not exist creates it, and created that way with no members array the caller becomes created_by and is not a member.

That one fact explains all four symptoms at once:

symptom cause
header shows dm-cmqb… channelUtils filters the viewer out of the members, finds nobody, falls through to channel.id
"No members" same zero
"hi" sends fine the creator can post
gone on refresh the sidebar queries { members: { $in: [me] } }

It reproduces identically against a stranger. The phantom is not a property of the pair — it is a property of the id not existing.

Why the id was missing. The three answers to "are these two connected?" disagreed:

statuses
checkUserRelationship APPROVED, SCHEDULED (+ subscription window open)
getDmPairsForUser (reconciler) APPROVED, SCHEDULED
the two search routes APPROVED, APPROVED_PENDING_PAYMENT, SCHEDULED, COMPLETED

Search was widest, so it offered rows the create path had never fired for. And checkUserRelationship — the only implementation of the rule, with a full unit-test suite — had zero production call sites. createDirectMessageChannel validated two non-empty strings: no session, no relationship query, not even a !== b. It was safe by accident, because every caller happened to be a booking-approval or payment-success path.

What changed

Eligibility is one definition, and it gates. DM_ELIGIBLE_STATUSES lives in a Prisma-free module so the reconciler, both search routes and the gate cannot drift apart again. Ever-transacted and permanent; the subscription scheduling window is gone, because a thread that closes at midnight on the renewal date closes mid-conversation and then looks stale to the reconciler. PENDING stays out, or anyone opens a channel by requesting a booking they never pay for.

⚠️ Widening the status set without widening MANAGED_CHANNEL_PREFIXES's expected set is the #1134 P0-7 failure mode. Both move in this commit, together.

The client never names a channel. POST /api/stream/channels/open takes a person or an event and re-derives the id server-side. A client-supplied channel id would be an authz bypass by construction — the id is a pure function of the two user ids, so anyone who can name a pair could name their channel. Both arms are idempotent and create with the full member list atomically, which is the whole difference from what watch() was doing.

Other holes closed on the way:

  • getDmChannelId throws on a self-pair. createChannel de-dupes members through a Set, so dm-a-a became a one-member channel with nobody to render and nobody to reply.
  • CreateChannelDialog stopped creating custom channels client-side, bypassing the admin/staff gate in the create route entirely. The option is now hidden for callers who cannot use it.
  • ChannelInfoAndManageDialog adds members through addMemberToChannel — the server-side gate that had been written for exactly this and never called.
  • searchUsersWithRelationships filters instead of ranking. hasRelationship was a sort key, so a two-character query returned every matching user on the platform; and the no-profile branch returned the full unfiltered match set precisely when the check could not run.
  • isEventOwner compared client.user.role against "CONSULTANT". That is the Stream role, which mapRoleToStream collapses to "user" for every consultant — so the host's remove-member control never rendered.

dmo- and dmh- were never registered, and "dmo-".startsWith("dm-") is false. getChannelTypeFromId returned "team" for org DMs created as messaging (four call sites addressed the wrong type), isDMChannel missed two of the three forms, and the reconciler never saw them. The block route now finds the DM by members: { $eq: [a, b] } instead of deriving the personal id it could never match for an org thread — and bans across every shared DM, since a block that leaves one thread writable is not a block.

Stream-side grants. scripts/stream/ensure-chat-type-grants.ts mirrors ensure-call-type-grants: dry-run default, --apply, --restore-user-create, and a refusal to apply without --open-route-is-deployed. Revokes create-channel and update-channel-members from user and guest, and sets user_search_disallowed_roles. guest matters as much as userguest_user_creation_disabled is false, so guest sessions are mintable with the public API key alone. Unlike call types there is no grandfathering problem: grants are evaluated per request against the type, so existing channels pick up the change.

Decisions recorded

Full rationale in docs/decisions/2026-08-15-chat-eligibility-and-client-channel-creation.md.

  • Consultation and subscription share one channel — confirmed, and already true since Stream SDK subsystem audit v2 — the webhook pipeline has never run, and any signed-in user can join any call #1134 P0-7. 04-chat-implementation.md still documented two separate formats; it now says what the code does.
  • Org scoping stays app-side. Stream's native multi-tenant teams is Elevate-tier and this app is on the free Maker account, so the org stays in the channel key plus custom.organization_id. ADR 19 needs the split anyway.
  • ADMIN/STAFF keep Stream admin — kept as-is, with the cost stated plainly (a staff token can read any DM from the browser) and the two rejected alternatives recorded in 07-user-management.md so the next reader has them.

Also dropped four stale facts about the sync cron from that doc: 03:30 not 03:40, two wrong paths, hard-delete documented where the code soft-deletes, and a personal account listed as hardcoded-excluded that is not in the code.

Verification

  • npx tsc --noEmit clean; eslint clean on the changed surface.
  • Full suite: 2957 passing. The 19 failures are the same 4 env-dependent suites (Razorpay keys, Supabase URL) that fail identically on a clean tree in this container — verified by stashing.
  • New: __tests__/security/dm-eligibility.test.ts (100% coverage of the gate) and __tests__/security/dm-channel-prefix-coverage.test.ts. The two reconciler assertions that pinned the narrow status set now reference the shared constant, so the drift that caused this cannot recur silently.

Not yet verified against the live app — worth doing before merge, since this subsystem has repeatedly looked correct in code and been broken in production:

  1. Sign in as a consultant, search a consultee's name → the row shows the consultee.
  2. Click it → header shows a name, two members; post; refresh; the thread persists.
  3. Derive a DM id for an unrelated pair by hand and watch() it from devtools → refused.
  4. npx tsx scripts/stream/ensure-chat-type-grants.ts (dry run), read the pre-image, then --apply --open-route-is-deployed. Dev, preview and prod share one Stream app — check the diff before writing.

📝 Walkthrough

Walkthrough

The change centralizes DM eligibility, supports additional DM channel ID formats, and moves channel creation and membership updates to server-side flows. Chat search, blocking, event reconciliation, Stream permissions, schemas, tests, and documentation now use the updated behavior.

Changes

DM security and channel management

Layer / File(s) Summary
Eligibility policy and enforcement
lib/stream/dm-eligibility*, actions/stream/chat/*.action.ts, __tests__/security/*, __tests__/stream/*-actions.test.ts
Shared eligible statuses now govern DM checks, search, and reconciliation. Bidirectional consultation and subscription relationships permit messaging. Self-pairs and ineligible pairs are rejected before channel creation.
DM identifiers and classification
lib/stream-channel-ids.ts, lib/stream-utils.ts, __tests__/security/dm-channel-prefix-coverage.test.ts
dm-, dmo-, and dmh- identifiers resolve to messaging channels and participate in reconciliation. Self-pair ID generation now throws an error.
Server-owned channel flow
app/api/stream/channels/open/route.ts, components/chat/ChannelSearch.tsx, components/chat/CreateChannelDialog.tsx, components/chat/ChannelInfoAndManageDialog.tsx
The server validates DM and event requests, derives channel IDs, authorizes access, and performs idempotent Stream updates. Clients no longer create channels directly.
Search, moderation, and channel display
app/api/stream/channels/search-appointments/route.ts, app/api/stream/search-consultees/route.ts, app/api/stream/search/route.ts, app/api/stream/users/block/route.ts, schemas/stream-search.ts, components/chat/*
Search uses session-derived identity, relationship filtering, counterparty fields, deterministic results, and race-safe requests. Blocking covers all shared DM channels. Phantom DMs are filtered and do not expose raw IDs.
Permissions and cleanup operations
scripts/stream/ensure-chat-type-grants.ts, scripts/stream/purge-memberless-dms.ts, .gitignore, providers/StreamProviderImpl.tsx
Stream permission changes and phantom-DM cleanup support dry runs, backups, restoration, deployment checks, pagination, and batched deletion. Stream connection deferral uses a 300 ms timeout.
Documentation and tests
docs/decisions/*, docs/stream/*, __tests__/*, .github/workflows/ci.yaml
Documentation records eligibility, server-owned channel flows, permissions, reconciliation, retention, role mapping, and soft deletion. Tests cover eligibility, channel prefixes, search races, phantom DMs, blocking, and authorization behavior.

Estimated code review effort: 5 (Critical) | ~120 minutes

Merge Risk: 🟠 High · up to 3f74c

This PR centralizes DM creation and expands server-side chat controls, but the current head can still let a caller add unauthorized users to direct messages and may cross-contaminate cached access tokens between users. These are high-impact security and data-isolation risks that should be fixed before merging.

Poem

A rabbit checks each booking line,
Then guards the channel gate.
IDs hop through Stream, neat and fine,
While self-pairs wait outside the gate.
Search finds friends, not ghosts in view,
And server paws make channels true.

Inline comments:
In `@actions/stream/chat/channel.action.ts`:
- Around line 170-174: Update the endpoint reference in the comment near the
relationship/session gate to use POST /api/stream/channels/open, matching the
route implemented by the open channel flow and used by ChannelSearch.

In `@actions/stream/chat/user.action.ts`:
- Around line 434-443: Adjust the user search flow around usersWithRelationships
so the Prisma query retrieves enough matches before applying the relatedUserIds
filter, then limit the filtered results to 20. Preserve the existing name
ordering and relationship metadata while ensuring eligible related users are not
removed by the pre-filter cap.

In `@app/api/stream/channels/open/route.ts`:
- Around line 126-136: Apply the existing rate-limit wrapper used by other
Stream routes to the POST handler, preserving the current requireApiAuth flow
and request behavior while limiting authenticated callers before database
queries or Stream operations execute. Reuse the established
wrapper/configuration rather than introducing a new rate-limiting
implementation.
- Around line 72-124: Update isEventParticipant to apply the same allowed status
constraint as the search route to both prisma.webinar.findFirst and
prisma.class.findFirst, while preserving the existing participant and owner
predicates.
- Around line 160-174: In app/api/stream/channels/open/route.ts lines 160-174,
use the channelId returned by createDirectMessageChannel and remove the
redundant getDmChannelId call and unused import. In lines 194-204, handle
DmNotPermittedError with a 403 response before Sentry capture; preserve the
existing handling for other errors.

Apply the same fix in `@app/api/stream/channels/open/route.ts` around lines 194 -
204.

In `@app/api/stream/users/block/route.ts`:
- Around line 68-81: Update the Stream lookup error path in the block route’s
query catch so lookup failures return a 5xx response directly instead of
assigning an empty dmChannels array and falling through to the 403 policy
response; preserve the existing 403 response only when the lookup succeeds with
no conversation.
- Around line 83-91: Update the ban loop around dmChannel.banUser to use
Promise.allSettled, allowing every channel ban attempt to complete. Continue to
prisma.moderationReport.create when at least one ban succeeds, and surface the
collected failures while preserving the existing all-failed error behavior.
- Around line 57-67: Update the shared-DM query in the block handler around
chatClient.queryChannels to paginate until all matching channels are fetched,
rather than limiting processing to the first 30 results. Preserve the exact
members.$eq filter and ensure query failures are caught and returned as a 5xx
response instead of falling through to the existing 403 response.

In `@components/chat/ChannelSearch.tsx`:
- Around line 241-245: Add type="button" to both result buttons in
ChannelSearch, including the button rendering handleConversationClick and the
event button near the corresponding second result block, to satisfy the
button-has-type rule and explicitly mark them as non-submit buttons.
- Around line 159-161: Update openResolvedChannel to use the discriminated
request-body shape instead of Record<string, unknown>, and guard the DM flow by
returning early when conversation.counterpartyUserId is missing or empty before
opening the channel. Ensure handleEventClick narrows or casts result.type to the
event-specific union so consultation and subscription values remain type-safe.
- Around line 171-181: Update the non-OK handling in openResolvedChannel to
provide visible non-error feedback, such as setting an openError message
rendered inside the dropdown, while preserving the existing 403 semantics. Clear
openError when openResolvedChannel starts and whenever a new search begins so
stale messages do not persist.

In `@components/chat/CreateChannelDialog.tsx`:
- Around line 167-197: Update the channel-creation branching in
CreateChannelDialog so the custom-channel request executes only when
selectedEvent is "custom" and canCreateCustomChannel is true. Reject or block
submission when selectedEvent is null, and preserve the existing webinar/class
selection requirements for non-custom events.

In `@docs/stream/07-user-management.md`:
- Around line 535-539: Update the documented erasure-gap section to state the
soft-delete retention window and identify who can still read the retained Stream
data, then explicitly state whether hard deletion should be triggered by the
erasure request or deferred to issue `#535`. Keep the existing references to the
DPDP §12 path and stream-sync reaper context.
- Around line 523-533: Update Step 5 in the deletion strategy documentation to
show user and messages configured for soft deletion, matching the sync job
implementation. Move the hard-deletion user/messages pair into the “Alternative
Options” section.

In `@lib/stream/dm-eligibility.ts`:
- Around line 53-125: Extract the identical direction-building logic from
hasConsultationLink and hasSubscriptionLink into a shared helper, then reuse it
in both functions while preserving the existing direction ordering and
empty-result behavior. Keep the Prisma query differences in each function,
including their respective model and plan relation keys.

In `@scripts/stream/ensure-chat-type-grants.ts`:
- Around line 180-183: Update scripts/stream/ensure-chat-type-grants.ts:180-183
so the opts.restore branch restores the preImage grants or removes only
permissions this script revoked, rather than re-adding all REVOKED_PERMISSIONS;
update scripts/stream/ensure-chat-type-grants.ts:229-229 to restore the preImage
user_search_disallowed_roles value or filter only USER_SEARCH_DISALLOWED_ROLES
instead of writing an empty array. Give the preImage written at
scripts/stream/ensure-chat-type-grants.ts:260 a stable, discoverable path so
later runs can load it.
- Around line 148-217: Reduce the cognitive complexity of ensureChatTypeGrants
by extracting computeGrants(existingGrants, opts) for grant calculation,
logGrantDiff(channelType, existingGrants, grants) for the per-role diff table,
and a helper for the app-settings logic currently handled later in the function.
Keep argument/configuration gating, apply/dry-run behavior, grant updates,
logging, and return behavior unchanged.
- Line 231: Update the sort calls in the comparison near canonical and inside
canonical to pass the existing byCodeUnit comparator explicitly, preserving the
current code-unit ordering and avoiding localeCompare.

Two live bugs found testing the branch, plus CodeRabbit's 18 comments.

The "Unavailable conversation" you could still type into was a fair hit: the
previous commit only changed the LABEL. channelUtils stopped printing the raw
channel id, which is cosmetic, and left the row selectable, openable and
writable. Renaming a broken thing does not fix it.

- isUsableDmChannel filters messaging channels with fewer than 2 members out of
  the sidebar at all three entry points (initial fetch, pagination, incremental
  refresh), so a phantom never reaches the rendered list. `team` is exempt: a
  webinar channel legitimately holds only its host until someone registers.
  Pagination still measures the RAW response length against the limit — a
  filtered count would report no-more-pages the moment one phantom is dropped.
- scripts/stream/purge-memberless-dms.ts deletes the ones already on Stream.
  Dry-run default, pre-image written BEFORE the delete (unlike the grants
  script, a delete is unrecoverable), paged at Stream's real 30-per-call cap.

The dropdown was partly mine: openResolvedChannel returned early on a non-OK
response, skipping the reset at the end of the function, so a 403 left the panel
open with no explanation. Outside-click and Escape never existed at all. Both
fixed, and the refusal is now rendered in the dropdown instead of console.error.

Review comments, all verified against current code:

- searchUsersWithRelationships applied `take: 20` BEFORE the relationship filter,
  so a common surname returned twenty strangers, filtered to zero, and never saw
  the actual client at position twenty-one. Over-fetch to 200, filter, slice to
  20. The two limits are now separate constants because they were competing for
  one budget.
- ensure-chat-type-grants' --restore-user-create re-added every entry in
  REVOKED_PERMISSIONS to every role and wrote [] for
  user_search_disallowed_roles — a rollback that grants access the change never
  removed, and wipes a setting it never set. Now restores from a pre-image at a
  stable repo-relative path (the old one was pid-suffixed in tmpdir and written
  AFTER the write, so it was unfindable on the later run that needs it, and
  absent entirely if the run failed halfway). Refuses to restore without one
  rather than guessing upward. Function split into computeGrants /
  logGrantDiff / syncUserSearchSetting for the complexity threshold.
- open route: isEventParticipant now applies the same status filter as
  search-appointments (a row you can see but cannot click is the same class of
  drift this PR exists to fix); uses the channelId createDirectMessageChannel
  returns instead of deriving it a second time; maps DmNotPermittedError to 403
  instead of 500+Sentry; rate-limited with streamApiLimiter, which already
  existed and had no callers.
- block route: a Stream lookup failure returned the 403 "you can only block
  users you have a conversation with" — an outage reported as a policy decision,
  at the exact moment someone needs the button to work. Now 503. The ban loop is
  Promise.allSettled so one transient failure no longer skips the remaining
  channels and the moderation report.
- CreateChannelDialog: `selectedEvent` initialises to null and the else branch
  caught it, so submitting without choosing posted a custom channel — which a
  consultant is not permitted to create. Three states now named explicitly.
- ChannelSearch: typed request body matching the route's discriminated union,
  guard on a missing counterpartyUserId, narrowed event type, button types,
  grouping extracted for the complexity threshold.
- dm-eligibility: buildDirections extracted; both link checks carried
  byte-identical copies, which is how a fix lands in one and not the other.
- 07-user-management: a second hard-delete block I missed, and the erasure gap
  now states the retention window, who can still read the data, and that hard
  deletion is deferred to #535.

Not changed, with the reasoning recorded for the thread: paginating the block
route past limit: 30. The filter matches channels whose membership is exactly
one pair — one personal thread plus at most one per org, and organizationLimit
is 5. Six is the ceiling; 30 is already 5x headroom.

.github/workflows/ci.yaml records the two-round review policy and its drawback:
stopping at two means a genuine round-3 finding gets a reply rather than a fix
here, which is the accepted cost of not looping on a profile that always finds
something.

.stream-backups/ is gitignored — the pre-images are snapshots of production
Stream configuration, not source.

Full suite 2967 passing, up from 2957 with the new tests. The 19 failures are
the same 4 env-dependent suites that fail on a clean tree in this container.

Persist failed channel IDs for retry, and return an explicit partial result or failure until every shared DM is blocked. Add a regression test with one fulfilled and one rejected ban result.

Round 2 of the agreed two. Four of the six findings are consequences of round
one's own fixes, which is what the second round is for.

- ChatSidebar pagination broke when I added the phantom filter. The offset was
  `directMessages.length`, which is now the FILTERED length, so every dropped
  phantom shifted the next page back by one: page two re-fetched rows already on
  screen and the tail became unreachable. The filter had silently eaten the
  pagination. Offset now comes from a ref holding the raw fetched count per
  list. Auto-select on load also read `dmResponse[0]` — the raw response — so it
  could open a phantom on arrival; it reads the filtered list now.

- purge-memberless-dms would have deleted collaborator channels. `messaging` is
  not the same as "DM": `collab-<webinar|class>-<planId>` is also `messaging`,
  and a collab channel legitimately sits at one member while co-host invitations
  are pending. Candidates are now gated on `isDMChannel(channel.id)` first —
  which only works because `dmo-`/`dmh-` were registered there earlier in this
  PR. A dry run reports DM-prefixed count separately from total scanned.

- ensure-chat-type-grants overwrote its own pre-image. Applying twice captured
  the already-modified state as the rollback target, so the second run quietly
  redefined "before" as "after" and --restore-user-create became a no-op that
  reports success — invisible until the day someone needs it. An existing
  pre-image is now kept unless --rebaseline is passed, and the write is
  write-then-rename so an interrupted run cannot leave a truncated file where a
  valid one was.

- A partial block was reported as a block. Switching the ban loop to
  allSettled in round 1 stopped it abandoning the remaining channels, but the
  route still answered success: true however many bans had actually landed — and
  the UI branches on response.ok alone, so it rendered "This user can no longer
  message you" over a thread they could still post in. Partial now answers 502
  with the counts and a message naming the shortfall; the moderation report is
  still written, because the attempt happened and the audit trail should not be
  conditional on a clean outcome. The client surfaces the server's message
  instead of a generic "Failed to block user".

- 07-user-management contradicted itself: a code comment promising a 30-day
  grace period two lines from prose explaining that nothing enforces it.

New: __tests__/security/block-partial-failure.test.ts pins all three outcomes
(all-succeed, some-succeed, none-succeed) plus the 503-not-403 lookup failure
and the genuine no-conversation 403.

SonarCloud's Reliability gate went D → A on the round-1 push.

Full suite 2973 passing, up from 2967. Same 19 pre-existing env failures.

Correcting my own bookkeeping. Round 2 fixed the `isDMChannel` scoping on this
file and I described the accompanying cognitive-complexity finding as
"addressed alongside" it — it was not. The function was untouched at complexity
30 against a limit of 15, and the review thread was resolved on that false
claim.

Split into the three things it was doing: toCandidate (is this deletable, and
what do we record), scanForCandidates (page and collect), reportCandidates
(print what an operator reads before applying), deleteCandidates (snapshot, then
batch delete). The orchestrator is now 30 lines with three branches.

toCandidate keeps the ordering that matters: prefix test before member count,
because a collab channel is `messaging` too and legitimately sits at one member
while co-host invitations are pending.

No behaviour change. SonarCloud's gate was already green — this is a
maintainability finding, not the reliability one — so this is finishing round 2
honestly rather than opening a round 3.

Neither problem was missing debouncing — there was already 300ms of it. More
would have made it slower without making it more accurate.

"No results found for michael" while Michael Chen sat in the list underneath:
the empty state was gated on `!loading`, but `setLoading(true)` runs INSIDE the
search, which fires 300ms after the keystroke. For that whole window `loading`
was false and no request existed, so the component announced failure before it
had looked — on every keystroke. Now gated on `settledQuery`, which tracks the
query the displayed results actually answer, so the empty state can only appear
after a real answer.

An empty search box with a stale result still listed: no AbortController and no
latest-wins guard, so `setSearchResults` committed whichever response landed
last regardless of which query it answered. Both now, per the same shape as
hooks/scheduling/useCalendarData.ts — abort stops the network work for a query
nobody is waiting on, and a requestId ref bumped before the first await guards
every state commit including the `loading` reset, because a response already
parsed is past cancelling and a stale reply's `finally` otherwise clears a
spinner a newer request is still waiting on.

Also in ChannelSearch: `openError` was cleared AFTER the short-query early
return, so a 403 refusal outlived the input that produced it and kept the
dropdown up over a blank search box — a second route to the "won't close"
report. And the "No results" box was a separate absolutely-positioned element
carrying the same `absolute z-50 mt-1 w-full` classes as the dropdown, so the
two overlapped whenever an error coexisted with an empty result set. One panel
now, three mutually exclusive states.

AddMembersDialog had all the same defects — hand-rolled setTimeout, no guard,
unconditional setState — plus `existingMemberIds` (an array prop) in the
callback deps, which re-armed the debounce timer on every render. Same
treatment, keyed on a joined string. Deliberately NO minimum-length guard
there: an empty term is a real query in that dialog, listing everyone the
consultant may add, and gating it would leave it blank until you typed. The
plan said to add one; that was wrong.

Both components now use `use-debounce`, already a dependency and already the
pattern in five other search inputs. These two were the only hand-rolled ones.

search-appointments ran its four findMany calls as sequential awaits, so every
keystroke paid the SUM of four round-trips to a remote database for queries
that never read each other's results. Promise.all pays the slowest one. Each
also gains a deterministic orderBy: with `take: 10` and no ordering, Postgres
returned an arbitrary ten and the `slice(0, 20)` cut a set that could differ
between two identical requests.

Rows now show the plan title. The route matches on plan titles as well as
names, so "michael" legitimately surfacing a conversation with Robert Brown —
who booked a plan called "Michael's…" — read as a broken search when only the
counterparty's name was on screen.

New __tests__/chat/channel-search-race.test.tsx resolves responses OUT of order
and asserts on the settled DOM; in-order tests cannot see either bug. One of
them caught a real fault first time, in the test helper rather than the
component: `Object.assign`-ing `name` onto a DOMException throws, because it is
a getter-only accessor, so the abort listener died and the promise never
rejected.

Deferred on purpose: pg_trgm indexes (none of the five searched columns is
indexed and ILIKE '%q%' cannot use btree, but this is already roadmapped at
50K-consultant scale) and search-consultees, which has no `take` at all and
filters in JS after loading every booking — logged as B2-4, needs its own fix
rather than a Promise.all over the top.

Full suite 2980 passing, up from 2973. Same 19 pre-existing env failures.

152-185: 🎯 Functional Correctness | 🔵 Trivial | ⚡ Quick win

Report partial add results and refresh the list after a failure.

The loop awaits each addMemberToChannel in sequence. If one call rejects, the loop stops. Members added before the rejection stay added, loadMembers() never runs, and AddMembersDialog shows one generic error. The operator cannot tell which members were added.

Attempt every id, then refresh and report the shortfall. This matches the partial-failure handling that app/api/stream/users/block/route.ts now uses.

…e the eager sync

The Messages skeleton was not the sync — my first guess was wrong. The sync is
already `void`-ed; `setChatConnected(true)` fires 29 lines before it is kicked
off. The skeleton clears when the socket connects, and nine serial round-trips
plus a deliberate idle wait gate that.

Two of the nine were dead. `useUserData` has exactly one consumer,
StreamProviderImpl, which destructures `{ userDetails, isLoading }` — but for a
CONSULTANT the hook fetched consultant-details and then reviews, SERIALLY, and
returned them for nobody to read. The connect is hard-gated on `isLoading`, so
two cold-lambda round-trips for discarded data sat directly between page load
and the chat socket. Removed, along with the state and imports they needed.

The idle deferral was `requestIdleCallback(..., { timeout: 2000 })`. On a cold
load that is not a ceiling but the actual wait: the main thread is saturated by
dashboard hydration and by evaluating the Stream chunk, so the browser never
finds an idle period and fires at the deadline every time. Kept the deferral —
it stops the handshake competing with first paint — at 300ms.

Separately, and this one IS mine: including COMPLETED in DM_ELIGIBLE_STATUSES
made the sync unbounded. COMPLETED is absorbing, so getDmPairsForUser returns
every consultation ever finished, neither query has a `take`, and the add pass
made a Stream call per pair five at a time on every cold load — 100 serial
waves for a consultant with 500 completed bookings, growing forever.

So the add pass is retired. syncUserEventChannels now computes the expected set
and runs the reconcile-and-remove pass only. Creation lives where it is needed:
POST /api/stream/channels/open provisions the one channel someone opens, and
booking approval and payment success still provision at transaction time. The
removal half stays on the sync because nothing else notices that a membership
ought to be revoked. addUserToDmChannel deleted with the pass — it duplicated
createDirectMessageChannel and, unlike it, ran no eligibility check.

Review round on fe240bd, 7 threads plus 4 outside-diff items:

- getDmChannelId throws on a self-pair, and search-appointments calls it in a
  loop over results, so ONE legacy self-booked row returned 500 for the whole
  query. I added that throw; the loops now skip such rows. This may be a
  second, uglier cause of the "No results found" report than the debounce
  flash I attributed it to.
- A full page of phantom DMs stranded the rest of the list: the filter empties
  `directMessages` while `hasMoreDMChannels` stays true, and the load-more
  button lived inside the non-empty branch, so the empty state rendered over an
  unreachable list. Load-more is now tied to hasMoreDMChannels alone and the
  empty state only claims emptiness when there is nothing left to fetch. Rated
  Major, correctly — also mine.
- A 5xx rendered as "No results found", which tells you the person does not
  exist. Failure is now its own state with its own panel.
- use-debounce v10 does not cancel on unmount; both components now call
  `.cancel()` alongside the abort.
- `exclude` was interpolated unencoded, so a member id containing & or + or a
  space corrupted the exclusion set.
- Partial-block Sentry reports carried a synthetic error and counts; they now
  carry the actual Stream rejection.
- Member adds are allSettled with a partial-result toast, matching the block
  route.
- purge-memberless-dms writes its pre-image write-then-rename, matching the
  grants script.
- Added the all-fail block test the suite header promised and did not have.

One test rewritten rather than kept green: "should handle partial failures
gracefully" asserted the add pass's success/fail tally. That pass no longer
exists, so it now asserts the opposite — that no Stream writes happen — while
still pinning that both pairs stay in the expected set, because narrowing that
set is how the reconciler evicts live conversations.

Full suite 2981 passing, up from 2980. Same 19 pre-existing env failures.

Two live bugs found testing the branch, plus CodeRabbit's 18 comments.

The "Unavailable conversation" you could still type into was a fair hit: the
previous commit only changed the LABEL. channelUtils stopped printing the raw
channel id, which is cosmetic, and left the row selectable, openable and
writable. Renaming a broken thing does not fix it.

- isUsableDmChannel filters messaging channels with fewer than 2 members out of
  the sidebar at all three entry points (initial fetch, pagination, incremental
  refresh), so a phantom never reaches the rendered list. `team` is exempt: a
  webinar channel legitimately holds only its host until someone registers.
  Pagination still measures the RAW response length against the limit — a
  filtered count would report no-more-pages the moment one phantom is dropped.
- scripts/stream/purge-memberless-dms.ts deletes the ones already on Stream.
  Dry-run default, pre-image written BEFORE the delete (unlike the grants
  script, a delete is unrecoverable), paged at Stream's real 30-per-call cap.

The dropdown was partly mine: openResolvedChannel returned early on a non-OK
response, skipping the reset at the end of the function, so a 403 left the panel
open with no explanation. Outside-click and Escape never existed at all. Both
fixed, and the refusal is now rendered in the dropdown instead of console.error.

Review comments, all verified against current code:

- searchUsersWithRelationships applied `take: 20` BEFORE the relationship filter,
  so a common surname returned twenty strangers, filtered to zero, and never saw
  the actual client at position twenty-one. Over-fetch to 200, filter, slice to
  20. The two limits are now separate constants because they were competing for
  one budget.
- ensure-chat-type-grants' --restore-user-create re-added every entry in
  REVOKED_PERMISSIONS to every role and wrote [] for
  user_search_disallowed_roles — a rollback that grants access the change never
  removed, and wipes a setting it never set. Now restores from a pre-image at a
  stable repo-relative path (the old one was pid-suffixed in tmpdir and written
  AFTER the write, so it was unfindable on the later run that needs it, and
  absent entirely if the run failed halfway). Refuses to restore without one
  rather than guessing upward. Function split into computeGrants /
  logGrantDiff / syncUserSearchSetting for the complexity threshold.
- open route: isEventParticipant now applies the same status filter as
  search-appointments (a row you can see but cannot click is the same class of
  drift this PR exists to fix); uses the channelId createDirectMessageChannel
  returns instead of deriving it a second time; maps DmNotPermittedError to 403
  instead of 500+Sentry; rate-limited with streamApiLimiter, which already
  existed and had no callers.
- block route: a Stream lookup failure returned the 403 "you can only block
  users you have a conversation with" — an outage reported as a policy decision,
  at the exact moment someone needs the button to work. Now 503. The ban loop is
  Promise.allSettled so one transient failure no longer skips the remaining
  channels and the moderation report.
- CreateChannelDialog: `selectedEvent` initialises to null and the else branch
  caught it, so submitting without choosing posted a custom channel — which a
  consultant is not permitted to create. Three states now named explicitly.
- ChannelSearch: typed request body matching the route's discriminated union,
  guard on a missing counterpartyUserId, narrowed event type, button types,
  grouping extracted for the complexity threshold.
- dm-eligibility: buildDirections extracted; both link checks carried
  byte-identical copies, which is how a fix lands in one and not the other.
- 07-user-management: a second hard-delete block I missed, and the erasure gap
  now states the retention window, who can still read the data, and that hard
  deletion is deferred to #535.

Not changed, with the reasoning recorded for the thread: paginating the block
route past limit: 30. The filter matches channels whose membership is exactly
one pair — one personal thread plus at most one per org, and organizationLimit
is 5. Six is the ceiling; 30 is already 5x headroom.

.github/workflows/ci.yaml records the two-round review policy and its drawback:
stopping at two means a genuine round-3 finding gets a reply rather than a fix
here, which is the accepted cost of not looping on a profile that always finds
something.

.stream-backups/ is gitignored — the pre-images are snapshots of production
Stream configuration, not source.

Full suite 2967 passing, up from 2957 with the new tests. The 19 failures are
the same 4 env-dependent suites that fail on a clean tree in this container.

… blocks

Round 2 of the agreed two. Four of the six findings are consequences of round
one's own fixes, which is what the second round is for.

- ChatSidebar pagination broke when I added the phantom filter. The offset was
  `directMessages.length`, which is now the FILTERED length, so every dropped
  phantom shifted the next page back by one: page two re-fetched rows already on
  screen and the tail became unreachable. The filter had silently eaten the
  pagination. Offset now comes from a ref holding the raw fetched count per
  list. Auto-select on load also read `dmResponse[0]` — the raw response — so it
  could open a phantom on arrival; it reads the filtered list now.

- purge-memberless-dms would have deleted collaborator channels. `messaging` is
  not the same as "DM": `collab-<webinar|class>-<planId>` is also `messaging`,
  and a collab channel legitimately sits at one member while co-host invitations
  are pending. Candidates are now gated on `isDMChannel(channel.id)` first —
  which only works because `dmo-`/`dmh-` were registered there earlier in this
  PR. A dry run reports DM-prefixed count separately from total scanned.

- ensure-chat-type-grants overwrote its own pre-image. Applying twice captured
  the already-modified state as the rollback target, so the second run quietly
  redefined "before" as "after" and --restore-user-create became a no-op that
  reports success — invisible until the day someone needs it. An existing
  pre-image is now kept unless --rebaseline is passed, and the write is
  write-then-rename so an interrupted run cannot leave a truncated file where a
  valid one was.

- A partial block was reported as a block. Switching the ban loop to
  allSettled in round 1 stopped it abandoning the remaining channels, but the
  route still answered success: true however many bans had actually landed — and
  the UI branches on response.ok alone, so it rendered "This user can no longer
  message you" over a thread they could still post in. Partial now answers 502
  with the counts and a message naming the shortfall; the moderation report is
  still written, because the attempt happened and the audit trail should not be
  conditional on a clean outcome. The client surfaces the server's message
  instead of a generic "Failed to block user".

- 07-user-management contradicted itself: a code comment promising a 30-day
  grace period two lines from prose explaining that nothing enforces it.

New: __tests__/security/block-partial-failure.test.ts pins all three outcomes
(all-succeed, some-succeed, none-succeed) plus the 503-not-403 lookup failure
and the genuine no-conversation 403.

SonarCloud's Reliability gate went D → A on the round-1 push.

Correcting my own bookkeeping. Round 2 fixed the `isDMChannel` scoping on this
file and I described the accompanying cognitive-complexity finding as
"addressed alongside" it — it was not. The function was untouched at complexity
30 against a limit of 15, and the review thread was resolved on that false
claim.

Split into the three things it was doing: toCandidate (is this deletable, and
what do we record), scanForCandidates (page and collect), reportCandidates
(print what an operator reads before applying), deleteCandidates (snapshot, then
batch delete). The orchestrator is now 30 lines with three branches.

toCandidate keeps the ordering that matters: prefix test before member count,
because a collab channel is `messaging` too and legitimately sits at one member
while co-host invitations are pending.

No behaviour change. SonarCloud's gate was already green — this is a
maintainability finding, not the reliability one — so this is finishing round 2
honestly rather than opening a round 3.

…rips

Neither problem was missing debouncing — there was already 300ms of it. More
would have made it slower without making it more accurate.

"No results found for michael" while Michael Chen sat in the list underneath:
the empty state was gated on `!loading`, but `setLoading(true)` runs INSIDE the
search, which fires 300ms after the keystroke. For that whole window `loading`
was false and no request existed, so the component announced failure before it
had looked — on every keystroke. Now gated on `settledQuery`, which tracks the
query the displayed results actually answer, so the empty state can only appear
after a real answer.

An empty search box with a stale result still listed: no AbortController and no
latest-wins guard, so `setSearchResults` committed whichever response landed
last regardless of which query it answered. Both now, per the same shape as
hooks/scheduling/useCalendarData.ts — abort stops the network work for a query
nobody is waiting on, and a requestId ref bumped before the first await guards
every state commit including the `loading` reset, because a response already
parsed is past cancelling and a stale reply's `finally` otherwise clears a
spinner a newer request is still waiting on.

Also in ChannelSearch: `openError` was cleared AFTER the short-query early
return, so a 403 refusal outlived the input that produced it and kept the
dropdown up over a blank search box — a second route to the "won't close"
report. And the "No results" box was a separate absolutely-positioned element
carrying the same `absolute z-50 mt-1 w-full` classes as the dropdown, so the
two overlapped whenever an error coexisted with an empty result set. One panel
now, three mutually exclusive states.

AddMembersDialog had all the same defects — hand-rolled setTimeout, no guard,
unconditional setState — plus `existingMemberIds` (an array prop) in the
callback deps, which re-armed the debounce timer on every render. Same
treatment, keyed on a joined string. Deliberately NO minimum-length guard
there: an empty term is a real query in that dialog, listing everyone the
consultant may add, and gating it would leave it blank until you typed. The
plan said to add one; that was wrong.

Both components now use `use-debounce`, already a dependency and already the
pattern in five other search inputs. These two were the only hand-rolled ones.

search-appointments ran its four findMany calls as sequential awaits, so every
keystroke paid the SUM of four round-trips to a remote database for queries
that never read each other's results. Promise.all pays the slowest one. Each
also gains a deterministic orderBy: with `take: 10` and no ordering, Postgres
returned an arbitrary ten and the `slice(0, 20)` cut a set that could differ
between two identical requests.

Rows now show the plan title. The route matches on plan titles as well as
names, so "michael" legitimately surfacing a conversation with Robert Brown —
who booked a plan called "Michael's…" — read as a broken search when only the
counterparty's name was on screen.

New __tests__/chat/channel-search-race.test.tsx resolves responses OUT of order
and asserts on the settled DOM; in-order tests cannot see either bug. One of
them caught a real fault first time, in the test helper rather than the
component: `Object.assign`-ing `name` onto a DOMException throws, because it is
a getter-only accessor, so the abort listener died and the promise never
rejected.

Deferred on purpose: pg_trgm indexes (none of the five searched columns is
indexed and ILIKE '%q%' cannot use btree, but this is already roadmapped at
50K-consultant scale) and search-consultees, which has no `take` at all and
filters in JS after loading every booking — logged as B2-4, needs its own fix
rather than a Promise.all over the top.

Full suite 2980 passing, up from 2973. Same 19 pre-existing env failures.

… funding context, session-scoped search

Background design review + CodeRabbit triage on this PR surfaced six gaps,
all fixed here:

- canDirectMessage's shared-slot arm made any two attendees of one event
  mutually eligible; the /open route this PR adds would have been a
  user-reachable path to consultee↔consultee DMs, which the moderation ADR
  forbids. Arm removed from the gate and from searchUsersWithRelationships'
  related-user builder (search and gate must agree); tests flipped.
- POST /api/stream/channels/open validated nothing about the client-supplied
  organizationId: any org id could be minted into a dmo- key, and omitting it
  for an org-funded booking produced a personal-id channel the reconciler
  immediately evicts. Contexts are now read from the pair's own bookings via
  pairBookingContexts (bookingOrgId precedence) and validated/derived.
- isEventParticipant gains F-HIGH-2's retention guard: a COMPLETED event past
  the org's retention window no longer resurrects its hard-deleted channel.
- OPENABLE_EVENT_STATUSES moves to dm-eligibility-statuses and both search
  routes now import DM_ELIGIBLE_STATUSES/dmEligibleStatusFilter — killing the
  last hardcoded copies of the sets this PR exists to unify.
- user.action.ts: searchUsersWithRelationships derives identity from the
  session (the currentUserId parameter was a client-controlled impersonation
  handle); ungated checkUserRelationship (relationship oracle) and deprecated
  searchUsers (global PII search) exports removed with their tests.
- purge-memberless-dms keeps message-bearing channels by default;
  --purge-with-messages opts into destroying history. Grants script dry-run
  now exits non-zero on drift.

Rebased onto dev@2133454f (#1226/#1231): channel.action.ts keeps dev's
no-use-server header + adopt-on-duplicate-create alongside this PR's
assertCanDirectMessage gate; event-channel retires addUserToDmChannel while
keeping the sync session gate and retention filters.

…ng channels

A consultant could search two letters of their own name, open the row, send a
message, and lose the thread on refresh. Four symptoms, two defects, neither of
them "you can talk to yourself".

The label. search-appointments is correctly scoped — the caller must be the
consultee or the consultant on every row — but it labelled every row
`consultantName`. On a consultant's dashboard that names the viewer. The
channelId underneath always pointed at the real consultee. ChannelSearch then
grouped by that name, collapsing a consultation and a subscription into one row
subtitled "Consultation & Subscription". Rows now carry the counterparty
relative to the caller, group by channelId rather than by a display string, and
a consultant can finally search by their client's name.

The phantom channel. ChannelSearch opened results with
`client.channel(type, id).watch()` on a browser-computed id. `watch()` posts to
the channel query endpoint — the same one `create()` posts to — so watching an
id that does not exist creates it, with the caller as created_by and NO members.
That is the raw-id header (channelUtils finds no counterparty and falls through
to channel.id), the "No members", the message sending fine, and the
disappearance on reload (the sidebar lists `members: {$in: [me]}`). It
reproduces identically against a stranger.

The id was missing because the three answers to "are these two connected?"
disagreed — the reconciler and the gate used APPROVED/SCHEDULED while search
also accepted APPROVED_PENDING_PAYMENT and COMPLETED. And checkUserRelationship,
the only implementation of the rule, had zero production call sites:
createDirectMessageChannel validated two non-empty strings, with no session, no
relationship query, and no `a !== b`.

- DM_ELIGIBLE_STATUSES is now the single definition, in a Prisma-free module so
  the reconciler, both search routes and the gate cannot drift apart again.
  Ever-transacted and permanent; the subscription scheduling window is gone,
  because a thread that closes at midnight on the renewal date closes
  mid-conversation and then looks stale to the reconciler.
- POST /api/stream/channels/open takes a person or an event and re-derives the
  id server-side. A client-supplied channel id would be an authz bypass by
  construction, the id being a pure function of the two user ids.
- getDmChannelId throws on a self-pair. createChannel de-duplicates members
  through a Set, so `dm-a-a` became a one-member channel with nobody to render
  and nobody to reply.
- CreateChannelDialog stopped creating custom channels client-side, which
  bypassed the admin/staff gate in the create route entirely; the option is now
  hidden for callers who cannot use it. ChannelInfoAndManageDialog adds members
  through addMemberToChannel, the server-side gate that had never been called.
- searchUsersWithRelationships filters instead of ranking. hasRelationship was a
  sort key, so a two-character query returned every matching user on the
  platform, and the no-profile branch returned the full unfiltered match set
  precisely when the check could not run.

dmo- and dmh- were never declared in stream-channel-ids, and "dmo-" does not
start with "dm-": getChannelTypeFromId returned "team" for org DMs created as
messaging, isDMChannel missed two of the three forms, and the reconciler never
saw them. Registered, with MANAGED_CHANNEL_PREFIXES widened in the same change
as the status set so the sweep cannot outrun the expected set. The block route
now finds the DM by `members: {$eq: [a, b]}` instead of deriving the personal id
it could never match for an org thread, and bans across every shared DM.

isEventOwner compared client.user.role against "CONSULTANT"; that is the Stream
role, which mapRoleToStream collapses to "user" for every consultant, so the
host's remove-member control never rendered.

scripts/stream/ensure-chat-type-grants.ts mirrors ensure-call-type-grants:
dry-run default, --apply, --restore-user-create, and a refusal to apply without
--open-route-is-deployed. Revokes create-channel and update-channel-members from
user and guest on messaging and team, and sets user_search_disallowed_roles.
guest matters as much as user — guest_user_creation_disabled is false, so guest
sessions are mintable with the public API key alone. Unlike call types there is
no grandfathering problem: grants are evaluated per request against the type.

Org scoping stays app-side. Stream's native multi-tenant `teams` is Elevate-tier
and this app is on the free Maker account, so the org stays in the channel key
plus custom.organization_id, which ADR 19 needs anyway.

Docs: 04-chat-implementation still documented consultation-/subscription-
channels that #1134 P0-7 deleted, and a DM example missing its own dm- prefix.
07-user-management records the decision to keep ADMIN/STAFF on Stream `admin`
along with the two rejected alternatives, and drops four stale facts about the
sync cron (03:30 not 03:40, wrong paths, hard delete not soft, and a personal
account listed as hardcoded-excluded that is not in the code).

Full suite: 2957 passing. The 19 failures are the same 4 env-dependent suites
that fail on a clean tree (missing Razorpay and Supabase env in this container).

Two live bugs found testing the branch, plus CodeRabbit's 18 comments.

The "Unavailable conversation" you could still type into was a fair hit: the
previous commit only changed the LABEL. channelUtils stopped printing the raw
channel id, which is cosmetic, and left the row selectable, openable and
writable. Renaming a broken thing does not fix it.

- isUsableDmChannel filters messaging channels with fewer than 2 members out of
  the sidebar at all three entry points (initial fetch, pagination, incremental
  refresh), so a phantom never reaches the rendered list. `team` is exempt: a
  webinar channel legitimately holds only its host until someone registers.
  Pagination still measures the RAW response length against the limit — a
  filtered count would report no-more-pages the moment one phantom is dropped.
- scripts/stream/purge-memberless-dms.ts deletes the ones already on Stream.
  Dry-run default, pre-image written BEFORE the delete (unlike the grants
  script, a delete is unrecoverable), paged at Stream's real 30-per-call cap.

The dropdown was partly mine: openResolvedChannel returned early on a non-OK
response, skipping the reset at the end of the function, so a 403 left the panel
open with no explanation. Outside-click and Escape never existed at all. Both
fixed, and the refusal is now rendered in the dropdown instead of console.error.

Review comments, all verified against current code:

- searchUsersWithRelationships applied `take: 20` BEFORE the relationship filter,
  so a common surname returned twenty strangers, filtered to zero, and never saw
  the actual client at position twenty-one. Over-fetch to 200, filter, slice to
  20. The two limits are now separate constants because they were competing for
  one budget.
- ensure-chat-type-grants' --restore-user-create re-added every entry in
  REVOKED_PERMISSIONS to every role and wrote [] for
  user_search_disallowed_roles — a rollback that grants access the change never
  removed, and wipes a setting it never set. Now restores from a pre-image at a
  stable repo-relative path (the old one was pid-suffixed in tmpdir and written
  AFTER the write, so it was unfindable on the later run that needs it, and
  absent entirely if the run failed halfway). Refuses to restore without one
  rather than guessing upward. Function split into computeGrants /
  logGrantDiff / syncUserSearchSetting for the complexity threshold.
- open route: isEventParticipant now applies the same status filter as
  search-appointments (a row you can see but cannot click is the same class of
  drift this PR exists to fix); uses the channelId createDirectMessageChannel
  returns instead of deriving it a second time; maps DmNotPermittedError to 403
  instead of 500+Sentry; rate-limited with streamApiLimiter, which already
  existed and had no callers.
- block route: a Stream lookup failure returned the 403 "you can only block
  users you have a conversation with" — an outage reported as a policy decision,
  at the exact moment someone needs the button to work. Now 503. The ban loop is
  Promise.allSettled so one transient failure no longer skips the remaining
  channels and the moderation report.
- CreateChannelDialog: `selectedEvent` initialises to null and the else branch
  caught it, so submitting without choosing posted a custom channel — which a
  consultant is not permitted to create. Three states now named explicitly.
- ChannelSearch: typed request body matching the route's discriminated union,
  guard on a missing counterpartyUserId, narrowed event type, button types,
  grouping extracted for the complexity threshold.
- dm-eligibility: buildDirections extracted; both link checks carried
  byte-identical copies, which is how a fix lands in one and not the other.
- 07-user-management: a second hard-delete block I missed, and the erasure gap
  now states the retention window, who can still read the data, and that hard
  deletion is deferred to #535.

Not changed, with the reasoning recorded for the thread: paginating the block
route past limit: 30. The filter matches channels whose membership is exactly
one pair — one personal thread plus at most one per org, and organizationLimit
is 5. Six is the ceiling; 30 is already 5x headroom.

.github/workflows/ci.yaml records the two-round review policy and its drawback:
stopping at two means a genuine round-3 finding gets a reply rather than a fix
here, which is the accepted cost of not looping on a profile that always finds
something.

.stream-backups/ is gitignored — the pre-images are snapshots of production
Stream configuration, not source.

Full suite 2967 passing, up from 2957 with the new tests. The 19 failures are
the same 4 env-dependent suites that fail on a clean tree in this container.

… blocks

Round 2 of the agreed two. Four of the six findings are consequences of round
one's own fixes, which is what the second round is for.

- ChatSidebar pagination broke when I added the phantom filter. The offset was
  `directMessages.length`, which is now the FILTERED length, so every dropped
  phantom shifted the next page back by one: page two re-fetched rows already on
  screen and the tail became unreachable. The filter had silently eaten the
  pagination. Offset now comes from a ref holding the raw fetched count per
  list. Auto-select on load also read `dmResponse[0]` — the raw response — so it
  could open a phantom on arrival; it reads the filtered list now.

- purge-memberless-dms would have deleted collaborator channels. `messaging` is
  not the same as "DM": `collab-<webinar|class>-<planId>` is also `messaging`,
  and a collab channel legitimately sits at one member while co-host invitations
  are pending. Candidates are now gated on `isDMChannel(channel.id)` first —
  which only works because `dmo-`/`dmh-` were registered there earlier in this
  PR. A dry run reports DM-prefixed count separately from total scanned.

- ensure-chat-type-grants overwrote its own pre-image. Applying twice captured
  the already-modified state as the rollback target, so the second run quietly
  redefined "before" as "after" and --restore-user-create became a no-op that
  reports success — invisible until the day someone needs it. An existing
  pre-image is now kept unless --rebaseline is passed, and the write is
  write-then-rename so an interrupted run cannot leave a truncated file where a
  valid one was.

- A partial block was reported as a block. Switching the ban loop to
  allSettled in round 1 stopped it abandoning the remaining channels, but the
  route still answered success: true however many bans had actually landed — and
  the UI branches on response.ok alone, so it rendered "This user can no longer
  message you" over a thread they could still post in. Partial now answers 502
  with the counts and a message naming the shortfall; the moderation report is
  still written, because the attempt happened and the audit trail should not be
  conditional on a clean outcome. The client surfaces the server's message
  instead of a generic "Failed to block user".

- 07-user-management contradicted itself: a code comment promising a 30-day
  grace period two lines from prose explaining that nothing enforces it.

New: __tests__/security/block-partial-failure.test.ts pins all three outcomes
(all-succeed, some-succeed, none-succeed) plus the 503-not-403 lookup failure
and the genuine no-conversation 403.

SonarCloud's Reliability gate went D → A on the round-1 push.

Correcting my own bookkeeping. Round 2 fixed the `isDMChannel` scoping on this
file and I described the accompanying cognitive-complexity finding as
"addressed alongside" it — it was not. The function was untouched at complexity
30 against a limit of 15, and the review thread was resolved on that false
claim.

Split into the three things it was doing: toCandidate (is this deletable, and
what do we record), scanForCandidates (page and collect), reportCandidates
(print what an operator reads before applying), deleteCandidates (snapshot, then
batch delete). The orchestrator is now 30 lines with three branches.

toCandidate keeps the ordering that matters: prefix test before member count,
because a collab channel is `messaging` too and legitimately sits at one member
while co-host invitations are pending.

No behaviour change. SonarCloud's gate was already green — this is a
maintainability finding, not the reliability one — so this is finishing round 2
honestly rather than opening a round 3.

…rips

Neither problem was missing debouncing — there was already 300ms of it. More
would have made it slower without making it more accurate.

"No results found for michael" while Michael Chen sat in the list underneath:
the empty state was gated on `!loading`, but `setLoading(true)` runs INSIDE the
search, which fires 300ms after the keystroke. For that whole window `loading`
was false and no request existed, so the component announced failure before it
had looked — on every keystroke. Now gated on `settledQuery`, which tracks the
query the displayed results actually answer, so the empty state can only appear
after a real answer.

An empty search box with a stale result still listed: no AbortController and no
latest-wins guard, so `setSearchResults` committed whichever response landed
last regardless of which query it answered. Both now, per the same shape as
hooks/scheduling/useCalendarData.ts — abort stops the network work for a query
nobody is waiting on, and a requestId ref bumped before the first await guards
every state commit including the `loading` reset, because a response already
parsed is past cancelling and a stale reply's `finally` otherwise clears a
spinner a newer request is still waiting on.

Also in ChannelSearch: `openError` was cleared AFTER the short-query early
return, so a 403 refusal outlived the input that produced it and kept the
dropdown up over a blank search box — a second route to the "won't close"
report. And the "No results" box was a separate absolutely-positioned element
carrying the same `absolute z-50 mt-1 w-full` classes as the dropdown, so the
two overlapped whenever an error coexisted with an empty result set. One panel
now, three mutually exclusive states.

AddMembersDialog had all the same defects — hand-rolled setTimeout, no guard,
unconditional setState — plus `existingMemberIds` (an array prop) in the
callback deps, which re-armed the debounce timer on every render. Same
treatment, keyed on a joined string. Deliberately NO minimum-length guard
there: an empty term is a real query in that dialog, listing everyone the
consultant may add, and gating it would leave it blank until you typed. The
plan said to add one; that was wrong.

Both components now use `use-debounce`, already a dependency and already the
pattern in five other search inputs. These two were the only hand-rolled ones.

search-appointments ran its four findMany calls as sequential awaits, so every
keystroke paid the SUM of four round-trips to a remote database for queries
that never read each other's results. Promise.all pays the slowest one. Each
also gains a deterministic orderBy: with `take: 10` and no ordering, Postgres
returned an arbitrary ten and the `slice(0, 20)` cut a set that could differ
between two identical requests.

Rows now show the plan title. The route matches on plan titles as well as
names, so "michael" legitimately surfacing a conversation with Robert Brown —
who booked a plan called "Michael's…" — read as a broken search when only the
counterparty's name was on screen.

New __tests__/chat/channel-search-race.test.tsx resolves responses OUT of order
and asserts on the settled DOM; in-order tests cannot see either bug. One of
them caught a real fault first time, in the test helper rather than the
component: `Object.assign`-ing `name` onto a DOMException throws, because it is
a getter-only accessor, so the abort listener died and the promise never
rejected.

Deferred on purpose: pg_trgm indexes (none of the five searched columns is
indexed and ILIKE '%q%' cannot use btree, but this is already roadmapped at
50K-consultant scale) and search-consultees, which has no `take` at all and
filters in JS after loading every booking — logged as B2-4, needs its own fix
rather than a Promise.all over the top.

Full suite 2980 passing, up from 2973. Same 19 pre-existing env failures.

…e the eager sync

The Messages skeleton was not the sync — my first guess was wrong. The sync is
already `void`-ed; `setChatConnected(true)` fires 29 lines before it is kicked
off. The skeleton clears when the socket connects, and nine serial round-trips
plus a deliberate idle wait gate that.

Two of the nine were dead. `useUserData` has exactly one consumer,
StreamProviderImpl, which destructures `{ userDetails, isLoading }` — but for a
CONSULTANT the hook fetched consultant-details and then reviews, SERIALLY, and
returned them for nobody to read. The connect is hard-gated on `isLoading`, so
two cold-lambda round-trips for discarded data sat directly between page load
and the chat socket. Removed, along with the state and imports they needed.

The idle deferral was `requestIdleCallback(..., { timeout: 2000 })`. On a cold
load that is not a ceiling but the actual wait: the main thread is saturated by
dashboard hydration and by evaluating the Stream chunk, so the browser never
finds an idle period and fires at the deadline every time. Kept the deferral —
it stops the handshake competing with first paint — at 300ms.

Separately, and this one IS mine: including COMPLETED in DM_ELIGIBLE_STATUSES
made the sync unbounded. COMPLETED is absorbing, so getDmPairsForUser returns
every consultation ever finished, neither query has a `take`, and the add pass
made a Stream call per pair five at a time on every cold load — 100 serial
waves for a consultant with 500 completed bookings, growing forever.

So the add pass is retired. syncUserEventChannels now computes the expected set
and runs the reconcile-and-remove pass only. Creation lives where it is needed:
POST /api/stream/channels/open provisions the one channel someone opens, and
booking approval and payment success still provision at transaction time. The
removal half stays on the sync because nothing else notices that a membership
ought to be revoked. addUserToDmChannel deleted with the pass — it duplicated
createDirectMessageChannel and, unlike it, ran no eligibility check.

Review round on fe240bd, 7 threads plus 4 outside-diff items:

- getDmChannelId throws on a self-pair, and search-appointments calls it in a
  loop over results, so ONE legacy self-booked row returned 500 for the whole
  query. I added that throw; the loops now skip such rows. This may be a
  second, uglier cause of the "No results found" report than the debounce
  flash I attributed it to.
- A full page of phantom DMs stranded the rest of the list: the filter empties
  `directMessages` while `hasMoreDMChannels` stays true, and the load-more
  button lived inside the non-empty branch, so the empty state rendered over an
  unreachable list. Load-more is now tied to hasMoreDMChannels alone and the
  empty state only claims emptiness when there is nothing left to fetch. Rated
  Major, correctly — also mine.
- A 5xx rendered as "No results found", which tells you the person does not
  exist. Failure is now its own state with its own panel.
- use-debounce v10 does not cancel on unmount; both components now call
  `.cancel()` alongside the abort.
- `exclude` was interpolated unencoded, so a member id containing & or + or a
  space corrupted the exclusion set.
- Partial-block Sentry reports carried a synthetic error and counts; they now
  carry the actual Stream rejection.
- Member adds are allSettled with a partial-result toast, matching the block
  route.
- purge-memberless-dms writes its pre-image write-then-rename, matching the
  grants script.
- Added the all-fail block test the suite header promised and did not have.

One test rewritten rather than kept green: "should handle partial failures
gracefully" asserted the add pass's success/fail tally. That pass no longer
exists, so it now asserts the opposite — that no Stream writes happen — while
still pinning that both pairs stay in the expected set, because narrowing that
set is how the reconciler evicts live conversations.

Full suite 2981 passing, up from 2980. Same 19 pre-existing env failures.

… funding context, session-scoped search

Background design review + CodeRabbit triage on this PR surfaced six gaps,
all fixed here:

- canDirectMessage's shared-slot arm made any two attendees of one event
  mutually eligible; the /open route this PR adds would have been a
  user-reachable path to consultee↔consultee DMs, which the moderation ADR
  forbids. Arm removed from the gate and from searchUsersWithRelationships'
  related-user builder (search and gate must agree); tests flipped.
- POST /api/stream/channels/open validated nothing about the client-supplied
  organizationId: any org id could be minted into a dmo- key, and omitting it
  for an org-funded booking produced a personal-id channel the reconciler
  immediately evicts. Contexts are now read from the pair's own bookings via
  pairBookingContexts (bookingOrgId precedence) and validated/derived.
- isEventParticipant gains F-HIGH-2's retention guard: a COMPLETED event past
  the org's retention window no longer resurrects its hard-deleted channel.
- OPENABLE_EVENT_STATUSES moves to dm-eligibility-statuses and both search
  routes now import DM_ELIGIBLE_STATUSES/dmEligibleStatusFilter — killing the
  last hardcoded copies of the sets this PR exists to unify.
- user.action.ts: searchUsersWithRelationships derives identity from the
  session (the currentUserId parameter was a client-controlled impersonation
  handle); ungated checkUserRelationship (relationship oracle) and deprecated
  searchUsers (global PII search) exports removed with their tests.
- purge-memberless-dms keeps message-bearing channels by default;
  --purge-with-messages opts into destroying history. Grants script dry-run
  now exits non-zero on drift.

Rebased onto dev@2133454f (#1226/#1231): channel.action.ts keeps dev's
no-use-server header + adopt-on-duplicate-create alongside this PR's
assertCanDirectMessage gate; event-channel retires addUserToDmChannel while
keeping the sync session gate and retention filters.
Rebase kept two intents that textually merged but semantically broke: dev
removed channel.action.ts's directive (F-HIGH-1) while this PR wires
addMemberToChannel into a client dialog. Without the boundary the dialog
pulled auth-server (next/headers) into the client bundle and next build
failed. The action now lives in member.action.ts — a gated, client-callable
action file, the sanctioned shape per channel.action's header — with its
session read upgraded to getSession(true) for parity with the token gate.

…-field reliability

- addMemberToChannel (now client-callable via member.action) rejects
  direct-message channels outright: DM membership is pair-derived through
  canDirectMessage, and a creator naming a third member would have bypassed
  that eligibility gate with server credentials.
- ChannelInfoAndManageDialog reads the creator from created_by.id with
  created_by_id as fallback — queried channels populate the object form, so
  the host's remove/truncate controls silently vanished after a reload.
- ChannelSearch dismiss clears the term too, instead of swapping results for
  a false 'No results found'.
- createConsultationChannel/createSubscriptionChannel skip legacy self-booked
  rows instead of letting getDmChannelId's throw 500 the booking path.
- purge pre-images are per-run files (a retry can no longer overwrite the
  record of earlier batches), and an unconfigured Stream exits non-zero.
- pairBookingContexts pinned by tests; this PR's ADR records why the group
  arm was removed rather than claiming it still exists.
The self-pair guards widened createConsultationChannel/createSubscriptionChannel
to nullable returns; full-project tsc (stricter than the scoped run) flagged
the two happy-path assertions.
