BotRecord.teamId already references another team: either reject those bots or
implement an explicit atomic move that updates the previous team’s roster,
inherited channels, and related events. Ensure validation occurs before applying
changes and preserve the no-duplicate-bots invariant.
- Around line 82-86: Complete the team-deletion flow by clearing teamId from
surviving BotRecord entries, and when detaching channels, clear
GroupRecord.teamId while setting an explicit standalone rosterMode and

DELETE /api/teams/:id only removes the team and does not implicitly delete
channel transcripts.
- Line 117: The membership-mutation plan should use one validated store
operation for every write to memberIds, including inherited and custom roster
edits, bot deletion, and legacy /api/groups updates. Ensure this operation
enforces DM/team constraints, repairs and persists defaultResponder for both
roster modes, and is used by all affected routes and assignment flows.
- Around line 143-151: The team roster mutation flow must emit one standard
group event for every inherited channel whose materialized GroupRecord changes,
after the atomic update. Keep group events authoritative for channel state and
define their ordering relative to team and team.deleted events, ensuring a
team-only event is not used for propagated channel changes.
- Line 52: Update the plan’s existing-room attachment sections to explicitly
define the resulting roster mode, reconciliation of current memberIds with the
team roster, and defaultResponder normalization. Specify an atomic migration
operation that preserves the transcript and prevents active members from
changing silently, and require this behavior before PR 5.
- Around line 275-280: Resolve the channel-ordering decision before finalizing
PR 2: either define persisted manual ordering along with its API and event
behavior, or remove “reorder” from the PR 2 scope so it matches the selected
ordering model and avoids non-durable sidebar behavior.
- Around line 197-210: The resource lease policy must prevent Bot A and Bot B
from concurrently acquiring the same host computer. Update the “This computer”
resource definition and its acquisition/enforcement rules to key exclusivity by
host-computer identity, or explicitly model separate isolated computer resources
with unique identities, consistent with the plan’s exit-condition requirements.

Specify attach-existing-room roster behavior.
The plan promises attachment without transcript loss, but does not define whether the room becomes inherit or custom, how its current memberIds reconcile with the team roster, or how defaultResponder is normalized. Require an explicit mode and an atomic migration operation before PR 5. Otherwise attachment can silently change active members.

Define conflicts when assigning a bot to a second team.
BotRecord.teamId is single-valued, but team creation accepts existing bots and only validates that IDs are unique and exist. Selecting a bot already assigned to another team can remove it from the old team's effective roster and inherited channels. Reject assigned bots or require an explicit move that updates affected channels and events atomically.

Complete the team deletion contract.
TeamRecord derives its roster from BotRecord.teamId, but deletion only defines channel behavior. Clear teamId from surviving bots when the team is removed. When channels detach, clear GroupRecord.teamId and rosterMode or define a standalone mode while preserving memberIds. Also expose the separate explicit channel-delete operation; DELETE /api/teams/:id must not ambiguously delete transcripts.

Use one validated path for every membership mutation.
The plan scopes defaultResponder normalization to inherited refreshes, but custom roster edits, bot deletion, and legacy /api/groups writes also change memberIds. The existing server/store.test.ts contract at Lines 71-83 requires membership changes to repair and persist defaultResponder. Route all such writes through one store operation that validates DM/team constraints and normalizes the responder for both roster modes.

Emit channel events for propagated roster changes.
A team roster mutation updates each inherited channel's materialized GroupRecord. Existing group events are authoritative for channel changes, and server/store.test.ts Lines 426-440 verifies that group writes emit them. Require one normal group event per changed channel after the atomic update, and define ordering with team and team.deleted. A team event alone leaves client channel state stale.

Key the host-computer lease by resource identity.
The table marks This computer as Exclusive per bot. Bot A and Bot B can therefore acquire the same host computer concurrently. This contradicts the exit condition in Lines 293-300 and can corrupt shared computer or session state. Use one exclusive lease per host computer, or define separate isolated computer resources and enforce their identities.

Resolve the channel-ordering decision before PR 2.
PR 2 includes reorder, but Open Decisions leaves manual ordering unresolved and also permits sorting by recent activity. If manual ordering remains, define persisted ordering plus API and event behavior. Otherwise remove reorder from PR 2. This contradiction can produce non-durable sidebar behavior.

Hey Milind — nice to see this stacked on #342. The “same roster, several projects, don’t clone the bots” sentence is the right product. A few notes from living in the team-switcher model, in case they’re useful before the implementation slices: How #342 works today, as a workflow. You pick a team at the top of the sidebar (or All bots). That team is the place you are standing. New bot and new room both join that team — they get its That is why the current UI feels straightforward. A team is a separate roster you work inside, not one squad you drag through several project chats. Why that loop matches the harness. Today a bot is one turn and one computer. Create a bot in Launch, then switch teams, and you are looking at different people — so “busy” and “which Designer is this?” stay obvious. You never have to promise that the same agent is in two chats at once. Stand in a team, new bot and new room join it, switch and that cast is gone, All bots if you need the whole house: that is a rule that fits the runtime we actually have. A nested tree that treats a team as a reusable cast across Switcher vs channels. #342 is a filter: pick a team, the sidebar shows that roster. Rooms stay a flat list. This plan is a hierarchy: pick a team, then pick a project conversation under it. That’s a real product step, not a small delta on the switcher. I’d treat the nested sidebar as replacing the switcher UX rather than rebasing it in place — otherwise people learn two different meanings of “team.” (Yours: same bots in What Busy vs the promise. You already call this out: a nested list that still uses global The rest I would keep: #342 still has merge conflicts and a couple of integrity follow-ups in flight. If it’s easier, extracting just Thanks for writing it down in the open. |

First usable Channels slice shipped in #390: existing rooms migrate in place to Channels, users can create and move them under Work/Personal/project contexts, and the #381 rename/member editor carries over. The broader same-bot concurrency and resource-isolation phases in this plan remain follow-up work. |

Reviewed — looks good. The strongest part is 'Why this is not only a sidebar feature': calling out that runGroupMemberTurn's busy-guard is load-bearing (interruption, computer backends, cleanup all assume one active turn per bot) is exactly the honest framing that keeps an implementer from shipping crossed streams. Extending GroupRecord//api/groups rather than building a parallel engine, and keeping channel-busy state visible instead of hiding it until multi-turn safety actually lands, are the right calls. Planning-only scope, green CI — ready to merge as direction-setting.

The remaining plan has a compatibility problem with what already shipped, and a workflow collision if the later phases land on that language unchanged. I would not merge this as direction-setting until those two meanings are split.
What already shipped vs what this doc still promises
#390 productized rooms as Channels: New Channel, context (Work / Personal / a project), move between contexts, same transcript/folder/roster as today’s groups. It explicitly does not promise the same bot working in two conversations at once. bot.busy stays the safety boundary.
This plan still defines a Channel as something else: a project conversation under a reusable team roster, with inherited vs custom membership, and a definition of done that requires the same bot to stream in two channels at once.
Users who get #390 will learn: a channel is a room with a context label. If later PRs keep this document’s meaning, they will be taught: a channel is one of several projects for the same saved squad, and Mira in #website-launch is the same Mira in #acme-renewal and can be busy in both. Those are not the same product. Shipping the second on the first’s name is the bug.
#342 (if it ever lands) is a third meaning of team: a filter you stand in. New bot / new room join that roster; switch teams and you are looking at different people. This plan’s team is the opposite: one squad you reuse across many # chats. Same word, opposite navigation rule. The doc currently says to treat #342 as foundation for PR 1. That would bake the collision into the store (teamId on bots and on groups, with different owners).
#384 already files rooms and bots under shared section labels. #390’s contexts sit on that same axis. Nested Teams → #channels is a second hierarchy on the same sidebar.
Workflow that actually breaks
Not “people might not want Slack.” The break is:
-
Busy is global.
runGroupMemberTurnstill bails whenbot.busy. The plan is honest that a nested list without conversation-scoped turns is a fake. #390 shipped the nested-ish language (Channel) while keeping that guard. Fine for now. Unsafe if PR 2 of this plan presents inherited channels as “your Launch team, several projects” while Mira greys out in every other channel because she is typing next door. That is a workflow lie: the UI says she is a member of both; the runtime says she can only exist in one. -
Inherited roster vs explicit members. Today a channel/room has
memberIds. You add/remove people; that is the membership. Live inheritance (“team roster changes propagate”) means adding a bot to Launch silently puts them in#website-launchand#q4-kickoff. That is a different mental model from #390/#381, where you edit this conversation’s members. Mixing inherit + custom + “reset to team” on top of the editor users just got will fight that editor. -
Same bot, two computers/folders. Even without parallel reasoning, the plan’s later leases exist because one
BotRecordstill owns one Local VM / host-computer grant. Putting that identity in two project folders without leases is how two channels edit one checkout. That is a compatibility issue with the current one-bot-one-computer assumption, not a sidebar issue.
Proper fix
Do not use this document as the Channels roadmap anymore. Channels already means #390. Rewrite the leftover work as two separate follow-ups, neither of which redefines Channel or Team against the shipped UI.
Follow-up A — roster template (no runtime change).
A named list of bot ids. “New channel” can copy that list into memberIds once. After create, membership is the channel’s, edited with the existing #381 panel. No live inheritance, no rosterMode, no nested Teams tree. This is the “don’t clone Mira for the next client” workflow. It fits today’s bot.busy and today’s Channel.
Follow-up B — conversation-scoped turns (only if A is actually painful).
TurnKey = botId:threadId, then leases for the same folder / this computer. Do this because Scout has two tasks or two channels and the user is blocked, not because the sidebar looks like Slack. Until B exists, the UI must not promise parallel work. Status is “Mira is in #website-launch” — same as today.
Do not: rebase this plan onto #342 as if teamId meant the same thing; nest # under Teams in the sidebar while #390 contexts/sections already group channels; keep “same bot, two live streams” in the definition of done for a nav slice.
I would close this planning PR or retitle it to “roster templates + optional parallel turns” with an explicit note that Channel is already shipped in #390 and must not change meaning. Direction-setting that disagrees with the last merge is how we get two products in one sidebar.
