 4. `directorProfiles()` is the spawn catalog (`default-agents.ts`) — closed set minus skywalker. Plugin and local `.agents/agents/` profiles still load, but closed `DIRECTOR_IDS` cannot be overridden or aliased.
 5. Primary chat role is Skywalker: `buildChatRole()` → `createSkywalkerSystemPrompt()`. Product mutation tools (`write_file` / `edit_file` / `delete_file`) live in CORE (and `SKYWALKER_TOOLS`) so they are advertised on the primary without a `tool_search` round-trip. DIY tiny/bounded edits on the parent; spawn builder/docs directors for substantial work — a prompt judgment call, not a toolset strip. `PRIMARY_DENIED_PRODUCT_TOOLS` is gone. Shell file-writes stay denied; MCP tools are not re-filtered by a product-write deny list. There is no static per-profile write-path lock (CL-6952).
 
+   **Grok infer envelope.** `loadSessionChatPrompt` always appends `loadAgentContextExtensions` (`AGENTS.md`, capped at `MAX_AGENTS_MD_BYTES`) and advertises CORE+CATALOG full schemas via `advertisedToolNamesForSessionMode`. That assembly is family-agnostic — Grok does not substitute the trimmed director prompt (`buildSubAgentSystemPrompt` + `formatDirectorSystemPrompt`). Workers already use that trimmed path (no `AGENTS.md`, mounted-tool schemas only). Keep the infer envelope on Grok; do not strip `AGENTS.md` or core schemas. Measure in `src/agent/prompt-sizes.ts` (`assembleSkywalkerInferEnvelope` vs `assembleDirectorPrompt("skywalker", "grok")`).

    **Codex tool proxies.** When the active provider is Codex (`isCodexProviderName`), `createAgentToolset` and `runSubAgent` mount `apply_patch`, `shell`, and `update_plan` stringTools from `createCodexToolProxies`, all forwarding through the same posix `ToolRunner` seam (`runTool`) so permission plugins still apply. `apply_patch` parses the Codex envelope and forwards each op (`write_file` / `delete_file` / `read_file`). `shell` — the native Codex name is `shell`, not `exec_command` — normalizes Codex's `command` (string or `["bash","-lc",script]`-style argv array), `workdir`, and `timeout_ms` onto `run_shell`'s `{command, cwd?, timeout?}` and is gated by `allowShellFromCapabilities` (mirrors `allowDeleteFromCapabilities` against `run_shell`). `update_plan` maps Codex's `plan: [{step, status}]` onto `manage_tasks(action: "create")`; `pending`/`in_progress`/`completed` map to `todo`/`doing`/`done` — `manage_tasks`'s `cancelled` status has no Codex equivalent and is never produced by this proxy. Primary strips `apply_patch` after mount (Corbits DIY stays on `write_file` / `edit_file` / `delete_file`); `shell` and `update_plan` stay on primary (same classification as `run_shell` / `manage_tasks`). Build and docs worker allowlists (`BUILD_TOOLS` / `DOCS_TOOLS`) include `apply_patch` so Codex workers keep the proxy after the capability filter. `CORE_TOOL_NAMES` does not list it.
 
 6. There is no static write-path declaration on packages or profiles (CL-6952 removed it — no shipped director ever set one). Instead, `agent-fleet.ts` tracks each running dispatch by cwd; a new mutating dispatch that lands on the same cwd as a live mutating peer (`pending_init`/`running`, and not a declared read-only `modelRole` of `explore`/`plan`/`review`/`test`) records at most one `concurrent-lane-overlap` entry per cwd wave in `intervention-log.ts` (class `conflict`). The wave flag clears when no live mutating writer remains for that cwd. Terminal-but-unsettled lanes (for example cancelled with `finishedAt` set while the run promise has not reached `finally`) are pruned from the map and do not warn. This is advisory only — it never blocks the spawn, since cwd overlap does not prove the two lanes touch the same files.

 #### Background shell mode
 
-`run_shell` accepts `background: true` (shell-guard plugin, after the permission chain — a denied command spawns nothing). The starting call resolves `cwd` as usual and applies a per-call `timeout` only when passed (no 120s default on background), skips the pwd probe, spawns a detached process group via the registry in `src/shell/background-shell.ts`, and returns `{shell_id, status: "running"}` immediately; the retained shell cwd is never mutated by a background run. Limits: 8 running, 8 completed entries (ring; evicted ids collect as not-found — truncated output is spilled to a `tool-output:///bg-shell-<id>` blob named in the completion message). On process exit the host delivers `buildShellBackgroundMessage(exit)` (exit status, timed-out marker, ~2KB output preview, spill URI) through the same continuation channel as compaction — wired in all three loop hosts (TUI, exec, sub-agent). `shell_collect` (`{shell_id, action: "collect"|"cancel", wait_ms?}`, default non-blocking) retrieves status/output or kills the process group; it is ungated by design (cancel only kills the session's own child). Timeout keeps its meaning: expiry kills the group and reports exit code 124 with `timed_out: true`. The tool watchdog exempts background starts and `shell_collect` (same list as `spawn_agent`/`wait_agents`/`ask_director`). Toolset dispose calls `disposeAll("session closed")` before the posix teardown, so `/clear`, interrupt, and reload kill every live background process group.

Timeout keeps its meaning: expiry kills the group and reports exit code 124 with `timed_out: true`. The tool watchdog exempts background starts and `shell_collect` (same list as `spawn_agent`/`wait_agents`/`ask_director`) because collect's own wait cap bounds the poll. Surfaces that do not mount `shell_collect` (intern, migrator) do not advertise `background: true` and the registry is unwired — background starts fail closed. Parent abort, deadline, and `close_agent` release parked collect waiters and dispose live background groups; `interrupt_agent` only releases waiters so the session (and its children) stay resumable. Toolset dispose calls `disposeAll("session closed")` before the posix teardown, so `/clear`, interrupt, and reload kill every live background process group.
 
 - **Alt+Enter** queues a follow-up (kind `"queue"`) delivered only on **session-idle** — parent-idle **and** no live fleet lanes (`run` goes idle). Session-idle Alt+Enter is a no-op. **Ctrl+C** stops the run.
 
-Idle-with-fleet is shipped: after a non-blocking `spawn_agent` dispatch the parent turn can settle while workers keep running. The runner emits a `fleet` event carrying the live-lane count (same liveness rule as the progress strip: interrupted leftovers are not live); the bridge holds the run busy on that count, so mid-hold Enter upgrades to a new primary turn (sent immediately) instead of queueing a steer, follow-ups keep waiting for true session-idle, and any steer left pending at the hold's engagement delivers immediately — the parent it was steering has already stopped. While the hold is up and the parent is not processing, occupancy flushes mailbox mail (`driveMailboxMail` + `buildMailboxMailMessage`) on store subscribe and idle-with-fleet settle — one child done while siblings run is enough. Skip that shot when a fleet-dry open-task continuation is latched. Exec-primary `wait_agents` mounts with no yield predicate (`createWaitAgentsTool({ sessions, fleetRecords })`) and blocks to ready/timeout/abort; `shouldYieldWait` remains a supported-but-unwired tool option (no production mount passes it).

The workflow idle rail honors live helper occupancy, not the TUI idle-with-fleet seed: a live fleet is not a stuck parent, an empty fleet still auto-continues slash workflows, and occupancy / mailbox / operator inbounds reset the workflow idle counter. While the hold is up and the parent is not processing, occupancy flushes mailbox mail (`driveMailboxMail` + `buildMailboxMailMessage`) on store subscribe and idle-with-fleet settle — one child done while siblings run is enough. Skip that shot when a fleet-dry open-task continuation is latched. Both wakes wait for send to settle as accepted before taking reports; a pending Promise is not a continuation, and a failed or uncertain send idles the parent. Exec-primary `wait_agents` mounts with no yield predicate (`createWaitAgentsTool({ sessions, fleetRecords })`) and blocks to ready/timeout/abort; parent interrupt/abort cancels that parked waiter via the tool AbortSignal (`timed_out`, workers stay running) rather than a second waiter table. `interrupt_agent` on a child unblocks wait as interrupted through the mailbox overlay. `shouldYieldWait` remains a supported-but-unwired tool option (no production mount passes it).

An in-flight TUI `shell_collect` or `ask_director` is still bounded by the TUI stall watchdog, including after a tool batch resolves and after compact continuation re-entry, so a typical poll does not pin the turn. Concurrent same-name `shell_collect` calls still collide in `callIdByName` (one slot per name); a sibling collect finishing can drop the mapping and the remaining poll can lose that stall bound — a residual of the name-keyed tracker, not a hole in the post-tool / post-compact abort. `wait_agents` is exec-primary only and is not mounted on TUI.
   - `waitForApproval` (default **true** when unset) — freeze that budget while a permission prompt is open so a late approve still runs the tool. **Settings → Tools** toggles this live for the next tool call and persists it here. When **false**, the budget keeps ticking during the prompt; on expiry the tool is skipped and the modal is auto-dismissed. The freeze is bounded: after **30 minutes** with the prompt still unanswered the budget resumes ticking on its own, so a prompt that never becomes visible (overlay open, UI gone) cannot hang a tool run indefinitely.
 
   Optional `mcp` block bounds MCP tool calls (`mcp__*` names) specifically — unlike `tools.*`, this arms **unconditionally** even with no settings at all, defaulting to **5 minutes**, since a wedged MCP server otherwise hangs a call forever with nothing to bound it (CL-6895):
