fix(rooms): take a deleted bot out of the rooms it was in - #2123
AdityaUmale wants to merge 1 commit into
Conversation
Deleting a bot removed its record, transcripts and workspace but left its id
in every room's memberIds. The room then counted it on Manage members'
"Save · N bots" (5 for 4 visible bots), the roster check refused every save
from that panel ("unknown room member"), and a room the bot led kept
pointing its default responder at a bot that no longer existed.
deleteBot now removes the bot from each room it was in, lets the room's lead
fall back to the next member, and saves and announces the rooms. Startup
repairs rooms that already list a deleted bot, but only when the bot list was
actually read, so an unreadable bots.json can never empty rooms. Bot-to-bot
channels keep their pair.
Fixes MOCA-264

- Line 1914: Update Store.deleteBot so a saveGroups() failure preserves a
retryable deletion operation and retry resumes cleanup,
transcript/workspace/skill-state/bot-folder removal, and event emission even if
the bot was already removed from this.bots. Use a transactional recovery
sequence or durable deletion record, and add a failure-path test verifying
cleanup can complete after saveGroups() throws.

Make bot deletion recoverable when saveGroups() fails.
deleteBot persists the bot removal and updates this.bots before it saves the modified rooms. If saveGroups() throws, deletion stops before transcript, workspace, skill-state, and bot-folder cleanup. No deletion events are emitted.
A direct retry of Store.deleteBot returns false because the bot is already absent. For reviewed deletions, the persisted receipt can make a retry return the saved result without resuming cleanup.
Use a transactional recovery sequence or a durable deletion record so a group-save failure does not lose the cleanup operation. Add a failure-path test for saveGroups().

What changed
server/store.tsdeleteBot: after the bot list is saved, the deleted bot is removed from every room'smemberIds. A room it led falls back to its next member (normalizeGroupDefaultResponder), and the rooms are saved and announced with agroupchange. Bot-to-bot channels (dm) keep their pair.bots.jsonwas actually read, so an unreadable bot list can never empty rooms.Why
MOCA-264: "when adding the bots to a chat its showing the incorrect number (5 instead of 4)".
Deleting a bot removed its record, transcripts and workspace, but left its ID in every room. As a result:
checkedMemberIds) refused every save from that panel with "unknown room member", so the room's members couldn't be edited at all.How it was verified
Before and after on isolated fixture servers. A room with 4 bots, then its lead (Ben) deleted:
mainHeadless UI on this branch (
control-omb ui launch): after deleting a member, the header and the panel both say 3 bots, and the button says "Save · 3 bots". Unticking a bot gives "Save · 2 bots", and saving updates the header and server to 2.New tests in
server/store.test.ts:groupchange is emitted; and it survives a restart.bots.jsonnever empties rooms.1 and 2 fail on
main; 3 passes on both.Passed:
pnpm exec vitest runon store, independent-task-store, group-tasks, bot-deletion-write-failure e2e, chief-rooms e2e, room-coordination e2e, bot-visibility (unit and e2e), comms, delegations, decider-rooms e2e and team-setup-requests (12 files, 404 tests), pluspnpm typecheckandpnpm lint.I didn't run the full
pnpm test.Related: MOCA-265 (bots disappearing after a message, same reporter) didn't reproduce. A room carrying a deleted member may explain it.
Screenshots (UI changes)
None. The client is unchanged; the count is correct once the server stops keeping deleted members.
