-# Team Expansion (Recursive Workspaces)
-
-When a workspace is expanded into a team, it gains sub-workspaces while its own agent remains as the **team lead** (coordinator). This is recursive — sub-workspaces can themselves be expanded into teams, infinitely deep.
-
-## How It Works
-
-When Developer PM is expanded into a team:
-
-```
-Business Core
- |
- +-- Developer PM (agent stays, becomes coordinator)
- |
- +-- Frontend Agent (sub-workspace, private scope)
- +-- Backend Agent (sub-workspace, private scope)
- +-- QA Agent (sub-workspace, private scope)
-```
-
-- Developer PM's agent **still exists** and acts as coordinator
-- Developer PM receives incoming A2A messages from Business Core
-- Developer PM's agent decides how to delegate to sub-workspaces
-- Sub-workspaces talk to Developer PM and to each other (same level)
-- Sub-workspaces **cannot** talk to Business Core or any workspace outside the team
-
-## Communication Rules
-
-| Direction | Allowed? | Example |
-|-----------|----------|---------|
-| Parent level -> team lead | Yes | Business Core -> Developer PM |
-| Team lead -> sub-workspaces | Yes | Developer PM -> Frontend Agent |
-| Sub-workspace -> team lead | Yes | Frontend Agent -> Developer PM |
-| Sub-workspace <-> sibling | Yes | Frontend Agent <-> Backend Agent |
-| Outside -> sub-workspace directly | No (403) | Business Core -> Frontend Agent |
-| Sub-workspace -> outside directly | No | Frontend Agent -> Business Core |
-
-The team lead (Developer PM) is the **only** bridge between the team's internal world and the outside.
-
-## Scoped Registry
-
-Sub-workspaces register in the platform registry but with a **private scope**. The registry knows about them but enforces access control.
-
-```
-Registry:
- Business Core :8001 scope: public
- Developer PM :8002 scope: public
- Frontend Agent :8010 scope: private, parent=Developer PM
- Backend Agent :8011 scope: private, parent=Developer PM
- QA Agent :8012 scope: private, parent=Developer PM
-```
-
-- The platform can always discover any workspace (for provisioning, monitoring)
-- The parent workspace can discover its sub-workspaces
-- Sub-workspaces can discover their siblings (same parent)
-- Outside workspaces get a **403 Forbidden** if they try to discover a private sub-workspace
-
-## How to Expand
-
-Expansion is triggered via `POST /workspaces/:id/expand`. The platform reads the `sub_workspaces` list from the workspace's config and provisions each one. On the canvas, users right-click a workspace node and select "Expand into team."
-
-Collapsing is the inverse: `POST /workspaces/:id/collapse`. Sub-workspaces are stopped and removed.
-
-## What Happens on Expansion
-
-When Developer PM is expanded into a team, the hierarchy changes but the outside view doesn't. Business Core's parent/child relationship to Developer PM is unaffected — Developer PM still responds to the same A2A endpoint.
-
-The events fired:
-- `WORKSPACE_EXPANDED` with the new `sub_workspace_ids` in the payload
-- `WORKSPACE_PROVISIONING` for each new sub-workspace
-- `WORKSPACE_ONLINE` for each sub-workspace as they come up
-
-Communication rules are automatically derived from the new hierarchy — no manual wiring needed.
-
-## Canvas Behavior
-
-- Children render as embedded mini-cards (`TeamMemberChip`) inside the parent node, not as separate canvas nodes
-- Each mini-card shows full status: gradient bar, name, tier badge, skills pills, active tasks, descendant count
-- **Recursive rendering** up to 3 levels deep (`MAX_NESTING_DEPTH = 3`) — sub-cards can contain their own "Team" sections
-- Parent node dynamically resizes: 210-280px (no children), 320-450px (children), 400-560px (grandchildren)
-- Eject button (sky-blue arrow icon) on hover extracts a child from the team
-- "Extract from Team" also available in the right-click context menu
-- Double-click a team node to zoom/fit to the parent area
-- The parent workspace node shows a badge with total descendant count
-
-## Collapsing a Team
-
-The inverse of expansion, triggered via `POST /workspaces/:id/collapse`:
-
-1. Each sub-workspace agent wraps up current work and writes a handoff document to memory
-2. Sub-workspaces are stopped and removed
-3. The team lead's agent goes back to handling everything directly
-4. A `WORKSPACE_COLLAPSED` event fires
-
-Sub-workspace memory is cleaned up based on backend (see [Memory — Cleanup](../architecture/memory.md#cleanup-on-workspace-deletion)).
-
-## Deleting a Team Workspace
-
-When a team workspace is deleted:
-1. Platform shows a warning listing all sub-workspaces that will be deleted
-2. User can **drag sub-workspaces out** of the team before confirming (promotes them to the parent level)
-3. On confirmation, cascade delete removes the parent and all remaining sub-workspaces
-4. `WORKSPACE_REMOVED` events fire for each deleted workspace

+// class1_ast_gate_test.go — generic Class 1 leak gate per #2867 PR-A.
+//
+// What this gate prevents:
+// The tenant-hongming leak class — a handler iterates a YAML-derived
+// slice (ws.Children, sub_workspaces, etc.) and calls
+// `INSERT INTO workspaces` inside the loop body without first
+// checking whether a workspace with the same (parent_id, name) is
+// already there. Each call to such a handler doubles the tree.
+//
+// Why this is broader than TestCreateWorkspaceTree_CallsLookupBeforeInsert:
+// The existing gate is hard-coded to org_import.go's createWorkspaceTree.
+// That catches the specific function that triggered the original
+// incident — but a future handler written from scratch in a different
+// file would not be covered. This gate walks every production handler
+// .go file and applies a structural rule that does not depend on
+// function or file names.
+//
+// The rule (verbatim from #2867 PR-A):
+//
+// "No handler in handlers/ may iterate a slice (any RangeStmt) AND
+// call INSERT INTO workspaces inside the loop body without a
+// preceding SELECT id FROM workspaces WHERE name=$1 AND parent_id IS
+// NOT DISTINCT FROM $2 in the same function (== a lookupExistingChild
+// call, OR an ON CONFLICT clause baked into the same INSERT, OR an
+// explicit allowlist annotation)."
+//
+// Allowlist mechanism: a function whose body contains the exact comment
+// string `// class1-gate: idempotent-by-design` is treated as safe.
+// Use this only after writing a unit test that pins WHY the function
+// is safe. The annotation is intentionally awkward to type — it should
+// be rare.

+// Why these are NOT plain unit tests
+// ----------------------------------
+// The strict-sqlmock unit tests in storage_test.go pin which SQL
+// statements fire — they are fast and let us iterate without a DB. But
+// sqlmock CANNOT detect bugs that depend on the actual row state after
+// the SQL runs. In particular:
+//
+// - the WITH … DELETE … RETURNING CTE used by Sweep depends on
+// Postgres' `make_interval` function and the table's CHECK
+// constraints. sqlmock would happily accept a hand-written SQL
+// literal that Postgres rejects at runtime.
+// - the partial index `idx_pending_uploads_unacked` (created by the
+// Phase 1 migration) only catches a wrong WHERE predicate at real-
+// query-plan time.
+//
+// These tests close those gaps by booting a real Postgres, running the
+// production helpers, and SELECTing the row to verify the observable
+// state matches the expected outcome.

+// sweeper.go — periodic GC for the pending_uploads table.
+//
+// The platform's poll-mode chat-upload handler creates a row in
+// pending_uploads for every chat-attached file the canvas sends to a
+// poll-mode workspace. The workspace's inbox poller fetches the bytes
+// and acks the row, but two failure modes leak rows long-term:
+//
+// 1. Workspace fetches but never acks (network hiccup between GET
+// /content and POST /ack; workspace crashed between the two).
+// Phase 1's Get refuses to re-serve an acked row, but a never-
+// acked row could in principle be fetched repeatedly until expires_at.
+// Phase 2's workspace-side fetcher is idempotent; the worry is
+// only disk usage on the platform side.
+//
+// 2. Workspace never fetches at all (workspace was offline when the
+// row was written; the upload's TTL elapsed).
+//
+// This sweeper handles both. It runs every SweepInterval, deletes rows
+// in either category, and emits structured logs + Prometheus counters
+// so a stuck-fetch dashboard can spot the leak class.
+//
+// Failure isolation: a transient DB error must NOT crash the sweeper.
+// We log + continue; the next tick retries. ctx cancellation cleanly
+// shuts the loop down for graceful shutdown.

+"""Poll-mode chat-upload fetcher + URI cache for the standalone path.
+
+Companion to ``inbox.py``. When the workspace's inbox poller sees an
+``activity_logs`` row with ``method='chat_upload_receive'`` (written by
+the platform's ``uploadPollMode`` handler — workspace-server
+``internal/handlers/chat_files.go``), this module:
+
+ 1. Pulls the bytes from
+ ``GET /workspaces/:id/pending-uploads/:file_id/content``.
+ 2. Writes them to ``/workspace/.molecule/chat-uploads/-``
+ — same on-disk shape as the push-mode handler in
+ ``internal_chat_uploads.py``, so anything downstream that already
+ resolves ``workspace:/workspace/.molecule/chat-uploads/...`` URIs
+ works unchanged.
+ 3. POSTs ``/workspaces/:id/pending-uploads/:file_id/ack`` so Phase 3
+ sweep can clean up the platform-side ``pending_uploads`` row.
+ 4. Records a ``platform-pending:/ →
+ workspace:/workspace/.molecule/chat-uploads/...`` mapping in a
+ process-local cache so the chat message that arrives later
+ (referencing the platform-pending URI) gets rewritten before the
+ agent sees it.
+
+URI rewrite ordering — the chat message containing the
+``platform-pending:`` URI is logged by the platform AFTER the
+``chat_upload_receive`` row, so the inbox poller sees the upload-receive
+row first (lower activity_logs.id) and stages the bytes before the chat
+message arrives in the same poll batch (or a later one). The URI cache
+is therefore populated before the message_from_activity path needs it.
+A miss (network race, restart with stale cursor) is handled by keeping
+the original ``platform-pending:`` URI in the rewritten body — the agent
+will see something it can't open, which is preferable to silently
+dropping the URI.
+
+Auth — same Bearer token the inbox poller uses (``platform_auth.auth_headers``).
+Both endpoints are on the wsAuth-gated route, so this module can never
+read another tenant's bytes even if a token is misrouted.

+
+ Why this exists: the inbox poll loop used to call ``fetch_and_stage``

+ multiple files into chat at once), the loop blocked for
+ ``N × per_fetch_latency`` before processing the chat message that

+ before the agent saw the user's prompt. ``BatchFetcher`` runs the
+ fetches on a small thread pool (default 4 workers) so the stall is
+ bounded by ``ceil(N/W) × per_fetch_latency`` instead.
+
+ Connection reuse: one ``httpx.Client`` is shared across every fetch
+ in the batch. httpx clients carry a connection pool, so a second
+ fetch to the same platform host reuses the TCP+TLS handshake from
+ the first — measurable win when fetches happen back-to-back.
+
+ Correctness invariant the caller MUST preserve: the inbox loop is
+ expected to call ``wait_all()`` before processing the chat-message
+ activity row that REFERENCES one of these uploads. Without the
+ barrier, the URI cache is empty when ``rewrite_request_body`` runs
+ and the agent sees the un-rewritten ``platform-pending:`` URI. The

+ pins this end-to-end.

+"""RFC #2873 iter 3 — drift gate + behavior tests for the post-split surface.
+
+The bulk of the heartbeat / resolver behavior is exercised by
+``test_mcp_cli.py`` and ``test_mcp_cli_multi_workspace.py`` through the
+``mcp_cli._symbol`` back-compat aliases. This file pins:
+
+ 1. The split is **behavior-neutral via aliasing** — every previously-
+ exposed ``mcp_cli._foo`` symbol is the SAME callable as the new
+ module's authoritative function. If a refactor accidentally drops
+ an alias or points it at a stale copy, this fails.
+
+ 2. ``mcp_inbox_pollers.start_inbox_pollers`` works for both single-
+ workspace (legacy back-compat) and multi-workspace shapes.
+ ``mcp_cli`` had no direct test for this branch before the split.
