Closes #4188

Issue #4188 | Hub #4138 | Spec #4137

Summary

Anyone allowed to add people to a Channel can now add a member directly, and that person gets access immediately, even to a private or role-only Channel. Each membership records how it was granted, so access follows that basis.

channelHumanAdd {channelId, humanId}           caller needs addMembers (Owner, channels.manageAll,
                                                Channel owner/admin, or everyone when allowed)
  → membership basis = invited                  stays until the person is removed
browse-and-join / roles visibility
  → membership basis = role                     ends when the granting role is revoked
channelMemberCandidates {channelId, query?}    → [{humanId, displayName, username}] (≤100, active non-members)
refusal                                        → permission-required, details.permission = 'addMembers'
CLI  channels add-member <id> <username> · channels member-candidates <id> --query <text>   (--as)
migration  channel-membership-basis (appended to the ledger)
 Members panel (Channel subpanel)
+  <AddPeopleAction>        shown only to people who may add members
+    <AddPeopleDialog>      search → choose → Add; plain-words refusal
   "Invite member" → "Invite a Bot"   (the old button invites Bots; renamed so the two are not confused)
 Team mode, Channel without Bots
+  members panel now shows (it was hidden, leaving no way to add people)
+  badge counts people and Bots; only your own row says "You"; other members see the Owner as "Owner"

Evidence

Real isolated Host on d33debd97, Owner + Alice + Bob, Web Client driven by UI and CLI. "Plans" is a private Channel whose addMembers is first admins:

Owner: Add people Owner: Alice added
Alice sees and reads the private Channel at once Alice (plain member, admins-only adding): no Add people
After --add-members everyone, Alice adds Bob
alice sees Plans before invitation              → false
owner Add people → Alice                        → Alice row in members; Alice's list shows Plans without reload
alice reads marker message                      → true
alice members panel (addMembers = admins)       → no Add people button
alice CLI channels add-member Plans bob         → permission-required, details {permission: addMembers}
policy → everyone; alice Add people → Bob       → Bob sees Plans, reads marker; bob CLI channels lists it
  • Host/CLI acceptance (Codex, Owner + two members, 68 CLI calls): private/roles/public invitation reads in list, stream, timeline and search; role-joined member loses access on role revoke while the name-invited member keeps it; persisted basis readback; refusals with --as.
  • All CI-selected affected suites (--maxWorkers=2): 7,489 passed, 16 skipped. Two failures in that run were checked: group-mention timed out under load and passes on rerun; memory-restore-report was a stale inventory hash after formatting, fixed in c63865494 (57/57 pass).
  • New tests: channel-add-people.test.ts (candidate parsing, payloads, who sees Add people, refusal text, select → refuse → add, member names from the viewer's side); M14 core regressions 14/14.
  • pnpm typecheck, pnpm lint, pnpm e2e:smoke pass.
  • Not run: scripts/e2e-group-management.mjs / e2e-client-interactions.mjs (only their button selector text changed to "Invite a Bot"; the label is covered by localization.test.ts). Installed Desktop and native mobile not checked; Web evidence only.
  • Known, out of scope: members see Owner-authored messages and previews as "Human" (legacy author name); tracked for Team mode: IM-style workspace pass (auto-join visible Channels, per-user sections) #4222.

Merge Danger

Door: one-way

Migration channel-membership-basis classifies existing memberships (documented in the M14 runtime notes). M7 (#4258) and M8 (#4165) also append ledger entries after migration-ledger; whichever lands later re-appends its entries by id.

Blast Radius: moderate

Channel membership reads and role-revoke cleanup; the members panel layout for Bot-less Channels in Team mode; the Bot invite button label.

Summary by CodeRabbit

  • New Features

    • Added controls for authorized team members to find and invite people to Channels, including private Channels.
    • Invitations grant immediate access and persist when a person’s roles change. Access based on Channel roles ends when those roles no longer qualify.
    • Added CLI commands to search for people available to add and invite them to a Channel.
    • Updated Channel member lists to include people alongside Bots.
    • Clarified the separate controls for inviting people and inviting Bots.
  • Documentation

    • Updated Channel and team-mode guidance in English and Chinese.
  • Bug Fixes

    • Updated membership handling so role-based access changes are reflected when roles or Channel visibility change.

Issue: #4188
Agent-Task: codex/local/01a1e0d6-b8e8-7961-81e3-9a956fccfd7f
Co-Authored-By: Codex <noreply@openai.com>
People who may add members to a Channel (Owner, all-Channels managers,
Channel owner and admins, or everyone when the Channel allows it) get an
Add people button. It searches the members they can add and gives the
chosen person access at once, even to a private Channel; an addMembers
refusal is explained in plain words. The Bot invite button is renamed
Invite a Bot so the two are not confused.

…mode

Without Bots the members panel was hidden, so nobody could reach Add
people. In Team mode it now shows, counts people as well as Bots, marks
only your own row as You, names the Owner for other members, and drops
the empty and managed-by-you notes when they do not apply.

Walkthrough

The change distinguishes named Channel invitations from role-based membership. It adds candidate search and invitation APIs, migrates existing memberships, ends role-based access when eligibility ends, and adds a client people picker with updated member displays and documentation.

Changes: Channel Invitations and Membership Access

Layer / File(s) Summary
Membership basis and role access
packages/core/src/database/schema-plan.ts, packages/core/src/team/channel-contract.ts, packages/core/src/team/channels.ts, packages/core/src/team/roles.ts, packages/core/src/team/service.ts, packages/core/src/plugin.ts, packages/core/test/*, docs/architecture/team-mode*
Channel memberships record role or invited as their basis. The migration classifies existing memberships. Role assignment, deletion, visibility changes, and ownership transfer end ineligible role-based memberships. Tests cover migration, access changes, and roster updates.
Candidate search and invitation APIs
packages/core/src/team/*, packages/core/src/bridge/rpc.ts, packages/core/src/bots/*, packages/core/test/*, docs/bot-cli*, .agents/skills/verify-deepseekbot/features/team-mode.md, changes/4188-channel-invitations.md, scripts/schema-migrations.json
The bridge and CLI add candidate search. The service checks addMembers authorization and returns up to 100 active people who are not Channel members. Tests cover candidate queries, invitations, authorization, and access behavior. Documentation describes the commands and verification checks.
Member picker and Channel panel
packages/client/src/client/*, packages/client/test/*, packages/browser/lib/client.js, packages/computer/lib/client.js, docs/channel-sidebar/groups*, scripts/e2e-*, scripts/verification-inventory.json
The Channel panel adds a people picker with candidate search and invitation feedback. Member counts and human-member labels are updated, and the members dock entry is shown in Team mode. Localized labels, invite-control documentation, and E2E selectors are updated.

Merge Risk: Low · up to 76197

The CLI help index suggests a channels list form that fails with a usage error. This misleads users but does not affect access control or data, and a one-line text fix resolves it. The rest of the change looks mergeable.

Full details: Title check

Explanation

The title "feat(team): Channel invitations grant access (M14)" matches the main change. The changeset adds direct Channel member invitations (channelHumanAdd), an invitation-basis membership that grants access regardless of visibility, member-candidate lookup, and the add-member CLI. The title is short, specific, and states the primary behavior.

Full details: Description check

Explanation

The description follows the repository template. It has a Closes #4188 line, a Summary, Evidence with real Host and CLI checks, and a Merge Danger section covering reversibility, blast radius, and review focus. It lists tests run, the tests not run (the two E2E scripts, Desktop, and native mobile), and the known out-of-scope issue. Two template parts are only partly met. The CI test plan mode (affected, full, or none) is not named. The description also does not say whether a scripts/ci-plan.mjs rule was updated, although the PR adds test files. The UI screenshots are embedded via R2 URLs as the template asks. Overall the description is mostly complete.

Full details: Linked Issues check

Explanation

[#4188] Requirements were checked against the whole-PR summary (merge base 52c5544 to head 7619779) and the listed code paths. No repository inspection was run, so the findings rely on summaries and author-reported acceptance evidence.

(1) Invitation grants access, any visibility: channels.ts adds requireAddMembers, checks the caller's addMembers right, and inserts members with membership_basis = 'invited'. The target no longer needs role eligibility. channelRoleEligibleSql in channel-contract.ts allows invited members. channelHumanAdd is in MEMBER_GLOBAL_METHODS and excluded from the channelId guard in bridge-access.ts. Tests in team-mode.test.ts and team-channel-membership-live.test.ts cover invited access to private and roles Channels.

(2) Access follows its basis: channelRoleMembershipExitSql ends role-based memberships. roles.ts runs it on role delete ('all') and on role set ('human'). channels.ts ends role memberships on visibility change. service.ts handles owner transfer. The channel-membership-basis migration classifies existing rows. Tests cover role-join removal and name-invited retention.

(3) Refusal: the summary states refusals return permission-required with details.permission = 'addMembers'. The client maps this to plain-language text (addPeopleErrorText). The dialog test covers refusal, then success.

(4) Picker and CLI: channelMemberCandidates is added to rpc.ts and bridge.ts (query capped at 200 characters). cli-team.ts adds member-candidates with --query. AddPeopleAction and AddPeopleDialog provide search and selection. cli-team.test.ts and bridge-rpc.test.ts cover the endpoints. The CLI add-member path is described in docs and the CLI search index.

(5) Immediate visibility: plugin.ts publishes a roster update on channels topic changes. The live roster test checks the changed event without another message.

(6) Real-Host and CLI verification with two members: the PR reports 68 CLI calls and UI evidence. This is author-reported and was not re-run here.

Uncertainty: channelRoleEligibleSql no longer grants eligibility through the owner/admin branch. The summary does not show whether Owners and admins keep access in role-visible Channels through another path. This was not verified in code. No concrete unmet requirement is shown. Non-coding items (manual testing, release coordination) are not assessed.

Full details: Out of Scope Changes check

Explanation

Changes were compared from merge base 52c5544 to head 7619779. Each group maps to #4188 or to a stated PR objective:

  • Core access and migration (channels.ts, channel-contract.ts, roles.ts, service.ts, schema-plan.ts, schema-migrations.json, bridge-access.ts, member-methods.ts): direct implementation of membership basis, role-based exit, and invitation authorization.
  • Bridge and CLI (rpc.ts, bridge.ts, cli-team.ts, bot-create-cli.ts): required CLI and bridge parity. The CLI search index entry describes the new commands.
  • Client UI (channel-add-people.tsx, team-channels-bridge.ts, locale.ts, group-member-controls.tsx, bot-main.tsx, channel-sidebar-builtins.tsx, channel-sidebar-icon.tsx): Add people action, dialog, member candidate loading, members panel visibility in Team mode for Bot-less Channels, and badge count. The PR objectives list these as in scope.
  • Bot invite relabel (locale.ts, e2e scripts, localization.test.ts, docs): disclosed in the PR. It separates the Bot invite control from Add people.
  • Member name display (memberHumanName): supports viewer-side member naming covered by the new tests. It does not change legacy message author labels, which the PR marks out of scope (#4222).
  • Generated bundle files packages/browser/lib/client.js and packages/computer/lib/client.js: add the user-plus glyph used by the Add people control. They are build outputs tied to the UI change.
  • Tests, docs, changelog, skill guide, and verification inventory: supporting changes for the above. Test changes to team-approvals and team-space-role-references adjust fixtures for the new access model.

No demonstrated unrelated change was found. Ignored files were not present in the inputs, and no excluded content was inspected.

Unverified finding
Verification ran but could not confirm this finding. It is shown for review, not as a verified issue.

Find the picker controls by role and accessible name.

The data-attribute lookups still succeed if the candidate button or Add button loses its accessible name. Use role-and-name queries scoped to the dialog, such as the candidate button named “Carol @carol” and the button named by channelPeople.submit.

This checks how users identify the controls and removes dependence on test-only attributes. Based on learnings, prefer “text content, ARIA roles, or accessible labels” over non-semantic test selectors.

- Line 231: Update the Add button’s submitDisabled condition to disable
submission whenever loadFailed is true, even if chosen still contains a
candidate from earlier results. Preserve the existing chosen-based disabling
behavior when loading has not failed.

Review comments at @packages/client/src/client/group-member-controls.tsx:
- Line 549: Update memberHumanName to determine the Owner label from the
member’s owner identity, not its display name. Keep the self-member path using
humanLabel, and use humanLabel for non-owner members named “Human”; apply the
Owner label only when the member matches the established owner identity.

Review comments at @packages/core/src/bots/bot-create-cli.ts:
- Line 2520: Update the channels search entry description so it advertises that
invoking channels with no arguments lists channels, rather than suggesting the
unsupported list action. Preserve the existing add-member and member-candidates
forms.

- Add is disabled when a later candidate search fails, so a hidden earlier
  choice cannot be submitted.
- Only the Owner's legacy row is named Owner; another member without a
  stored name stays Human.
- The channels CLI search entry shows the working list form.
