Make team import additive-only: allowlist boundary + numbered name collisions

[milind-soni]

Threat model

A team manifest is untrusted input: it can arrive from the remote team catalog, a GitHub URL, or a .json file someone shared. Whatever such a file claims, importing it must be additive-only — it may create new bots, and nothing else. It must never update, merge into, or grant anything on records the user already has, and an imported member must never arrive holding a privilege the user didn't hand it.

Audit of the current path found imports could not overwrite existing records (fresh newId() per member, zod strips unknown member keys, the v1 room block is parsed but never applied) — but the guarantee was implicit across three accidental layers with zero test coverage, and one real gap: a member wearing an existing bot's display name was created as an exact duplicate. Display names are identity wherever bots address each other (@mention resolution in rooms, the Chief of Staff roster, peer-approval prompts), so a shared file could plant an impostor that gets mentioned, granted, or listed as if it were the user's own bot.

What changed

• importedMemberProfile() (server/team-manifest.ts) is now the single boundary where a parsed member becomes bot fields. It's an allowlist built field by field — name, title, description, color, mascotExpression — so every privilege-bearing BotRecord field (autoApprove, alwaysAllow, chiefOfStaff, approvePeerComms, composio, computer, cloudBackend, cwd) is absent by construction, whatever the file claimed. A future manifest field can't reach a bot record without consciously widening this return type. The route still forces composio: false after creation — the one privilege where absence means allowed.
• Name collisions are numbered, never merged: "Mira" arrives as "Mira 2" (case-insensitive, hidden bots included, batch-internally unique, capped at the 100-char member limit) — the same convention the name generator already uses when its pool runs out.
• Documented behaviors: re-importing the same file creates a second, freshly numbered set and never reaches back into the first (user edits to imported bots survive). Replace-mode archival is unchanged and manifest-independent — the mode parameter the user chose decides it, and it touches only hidden/chiefOfStaff on their own bots.
• The import route in server/index.ts now goes through the boundary and carries the rationale.

Test plan

• Parse layer (team-manifest.test.ts): a member smuggling id, threadId, autoApprove, alwaysAllow, chiefOfStaff, approvePeerComms, composio, computer, cloudBackend, cwd, hidden, modelSelection parses to exactly the five persona fields (toEqual, so nothing extra can survive).
• Profile layer: allowlist output, collision numbering, case-insensitive + batch-forward numbering, max-length stem trimming.
• Route layer (index.test.ts): against an armed existing bot (every privilege ON, chief of staff, a room), a smuggling manifest creates a fresh-id bot with every privileged field at its safe default; the existing bot is untouched field for field; the single-Chief invariant holds; a legacy v1 room block neither creates nor mutates rooms; re-import after user edits leaves the edits intact and creates a new numbered record.
• Mutation-checked every guard: temporarily broke each one (dedup off; composio force removed; per-field write-through for all 6 patchable privileged fields; chief grab; merge-on-name-collision; loosened schema + raw spread; profile spread) and confirmed the corresponding test fails, then restored.
• pnpm typecheck and full pnpm test (vitest 112 files / 1076 passed, broker, updater, packaged-server smoke) green.

Summary by CodeRabbit

• Improvements
  • Team imports now create new bots without overwriting existing bots or user-edited settings.
  • Imported bots use safe default settings and only retain supported persona details.
  • Conflicting names are automatically adjusted with numbered suffixes, including case-insensitive matches.
  • Repeated imports create separate records, while legacy room data and untrusted manifest fields are ignored.

📝 Walkthrough

Walkthrough

Team imports now sanitize untrusted members into persona-only profiles, resolve case-insensitive name collisions, and create fresh bots with safe defaults. Tests cover additive behavior, rejected privileged fields, preserved existing state, repeated imports, and post-import edits.

Changes

Team import security and behavior

Layer / File(s)	Summary
Profile sanitization and collision handling server/team-manifest.ts, server/team-manifest.test.ts	importedMemberProfile allowlists persona fields, preserves optional mascot expressions, and creates unique names within the length limit.
Additive import wiring and defaults server/index.ts	Team imports track existing names and create fresh, non-greeting bots with Composio disabled. Existing bots and rooms are not modified or merged.
Import behavior integration coverage server/index.test.ts	Integration tests validate additive imports, safe defaults, identity handling, preserved edits, ignored legacy room data, and repeated imports.

Estimated code review effort: 3 (Moderate) | ~25 minutes

Merge Risk: 🟡 Moderate · up to 7722e

Concurrent imports or bot renames can still produce duplicate display names because collision checks occur before an asynchronous step, making mentions and roster entries ambiguous. Merge should wait for this bounded race to be closed.

2674-2697: 🩺 Stability & Availability | 🟠 Major | ⚡ Quick win

Take the takenNames snapshot after the await, not before it.

Line 2680 reads store.bots before await defaultSelection() on line 2682. That await yields the event loop. Another request can create a bot or rename one during the await window, for example a second POST /api/teams/import or a PATCH /api/bots/:id that sets name. The import loop then numbers against a stale name set and can create a bot whose display name duplicates an existing bot.

Display names are identity for @mention resolution and the Chief of Staff roster, so a duplicate name defeats the "no name captures" rule this code documents. The creation loop itself is synchronous, so moving the snapshot to just before the loop closes the window.

🔒️ Proposed fix: snapshot names after the last await

       const importedBots: ReturnType<typeof store.createBot>[] = [];
-      // Names already in use, hidden bots included: an archived bot can be
-      // un-archived later, and a revived duplicate would be just as
-      // ambiguous then. In replace mode this means re-importing your own
-      // export numbers the newcomers ("Mira 2") — the old team is only
-      // hidden, not gone, and Undo must never surface two bots wearing the
-      // same name.
-      const takenNames = new Set(store.bots.map((bot) => bot.name.trim().toLowerCase()));
       try {
         const selection = await defaultSelection();
+        // Names already in use, hidden bots included: an archived bot can be
+        // un-archived later, and a revived duplicate would be just as
+        // ambiguous then. In replace mode this means re-importing your own
+        // export numbers the newcomers ("Mira 2") — the old team is only
+        // hidden, not gone, and Undo must never surface two bots wearing the
+        // same name.
+        // Read AFTER the last await: the creation loop below is synchronous,
+        // so no concurrent request can add a name between this snapshot and
+        // the records it decides.
+        const takenNames = new Set(store.bots.map((bot) => bot.name.trim().toLowerCase()));
         for (const member of manifest.team.members) {
