Purpose

The AgentOrchestrator is the runtime brain of RoboCo: it owns the per-agent Docker container lifecycle, the per-tick dispatcher that matches tasks to agents, the stale-claim reaper, the provider rate-limit/overload park-and-probe recovery loop, and the default-off background engines (self-heal, CI-watch, dep-update, release-manager, strategy, external-PR poll, X-engine mentions poll, board roadmap engine, video render loop). It claims tasks on behalf of agents before spawning, injects briefings/manifests/git context at spawn time, provisions a per-spawn sandbox (postgres/redis/mongo via the engine registry) when opted in, captures per-session token usage, and persists durable runtime state (WaitingRecord, respawn_tracker) across restarts.

/Users/renzof/Documents/GitHub/ZZZ/roboco-master/roboco/roboco/runtime/orchestrator.py	Single 11485-line module: module helpers + the AgentOrchestrator class — container lifecycle, dispatchers, reaper, provider-parking, interactive intake/secretary spawns, background engine loops, token/cost capture, durable-state restore.	11485

Key Symbols

Name	Kind	File:Line	Responsibility
_system_api_headers	function	roboco/runtime/orchestrator.py:127	System-identity headers (X-Agent-ID/Role/Token) for the orchestrator's internal self-API calls so silent recovery ops pass auth-required.
_is_coordination_task	function	roboco/runtime/orchestrator.py:395	True for branchless tasks (product fan-out, ad-hoc cell map, MegaTask umbrella) via is_branchless_coordination; gates git-exemption sites.
_branch_is_expected	function	roboco/runtime/orchestrator.py:428	True iff a code task should already have a branch_name (claimed/in_progress/verifying, non-coordination); gates the missing-branch readiness/stuck condition.
_agent_worktree_path	function	roboco/runtime/orchestrator.py:473	Per-task worktree path under the clone root (F123) so parallel roots/tasks never clobber one shared checkout.
_agent_cwd_path	function	roboco/runtime/orchestrator.py:487	ONE formula for the container cwd + Edit/Write allowlist scope (worktree when branch present, else clone root) so -w and the allowlist never drift.
_build_manifest_for_agent	function	roboco/runtime/orchestrator.py:560	Write the per-role gateway SpawnManifest JSON to disk and return the host bind-mount path; None for non-gateway roles.
gateway_pre_spawn_check	function	roboco/runtime/orchestrator.py:687	Consult trigger_filter spawn-cooldown + provider rate-limit tracker; returns spawn/queue/drop, degrades to spawn on any error.
AgentReadinessError	class	roboco/runtime/orchestrator.py:796	Raised when spawn_agent refuses (task not ready / human role / worktree fatal); caller logs and moves on.
_SpawnAbortedDuringShutdown	class	roboco/runtime/orchestrator.py:804	Signals a non-blocking intake/secretary spawn completed docker run after shutdown began; raiser already removed the container.
AgentOrchestrator.new	method	roboco/runtime/orchestrator.py:909	Pre-initialize _instances = {}, _last_audit_spawn_at = None, and _notification_spawn_at = {} so tests/helpers that construct an orchestrator via bare AgentOrchestrator.__new__(...) to bypass __init__ do not crash when _is_agent_active, _dispatch_audit_work, or notification-cooldown paths read those attributes. __init__ still re-initializes _instances for normal construction.
AgentOrchestrator.init	method	roboco/runtime/orchestrator.py:920	Initialize instance/waiting/bg-task registries, locks (dispatch, supersede, intake/secretary spawn, respawn-persist), TTLs from settings, grok backoff state.
AgentOrchestrator.start	method	roboco/runtime/orchestrator.py:972	Ensure agent image, restore WaitingRecord + respawn_tracker, reconcile orphan claims, readopt running containers, launch all background loops.
AgentOrchestrator.stop	method	roboco/runtime/orchestrator.py:1057	Idempotent shutdown: cancel loops, stop agents (release_claim=True, skip provider-parked), drain bg writes, set _stopped.
AgentOrchestrator._drain_bg_tasks	method	roboco/runtime/orchestrator.py:1031	Bounded wait for fire-and-forget bg writes to commit before exit; cancels past _SHUTDOWN_DRAIN_TIMEOUT_SECONDS.
AgentOrchestrator._ensure_agent_image	method	roboco/runtime/orchestrator.py:1110	Build/pull base + role-specialized agent Docker images; idempotent; registry-mode pulls pre-built images.
AgentOrchestrator._get_role_permissions	method	roboco/runtime/orchestrator.py:1313	Build the Edit/Write/Read allowlist scoped to the agent's cwd (worktree or clone root) and cell workspace for documenters.
AgentOrchestrator._fable_hook_groups	method	roboco/runtime/orchestrator.py:1414	Default-off (fable_mode_enabled) Claude-path hook groups for 5 vendored fable-mode scripts (stop-gate/bash-discipline/honesty-nudge/prompt-nudge/precompact); appended AFTER RoboCo's own per-event hooks inside _generate_agent_settings.
AgentOrchestrator._task_git_context	method	roboco/runtime/orchestrator.py:1685	Build SpawnGitContext from a task payload; sets task_short_id (first 8 chars) only when a branch exists.
AgentOrchestrator._safe_spawn	method	roboco/runtime/orchestrator.py:1816	Build SpawnInputs and delegate to the resolved AgentProvider (grok) or built-in _spawn_container path.
AgentOrchestrator._prepare_agent_spawn	method	roboco/runtime/orchestrator.py:1930	Resolve project/team/cwd, ensure worktree, generate settings/permissions, write briefing + MCP config, compose prompt, ensure image, register STARTING instance.
AgentOrchestrator._ensure_worktree_before_spawn	method	roboco/runtime/orchestrator.py:2001	Idempotently re-attach a pruned task worktree before -w lands on it; fatal WorkspaceError releases claim + aborts, transient aborts without release.
AgentOrchestrator.spawn_agent	method	roboco/runtime/orchestrator.py:2141	Chokepoint spawn entry: validate path-segment, refuse human-only roles, readiness gate, resolve git context, provider-park pre-check, TOCTOU re-check, prepare + launch.
AgentOrchestrator._resolve_host_paths	method	roboco/runtime/orchestrator.py:2297	Compute host bind-mount paths for containerized vs host runtime (docs/workspaces/claude/mcp/grok-usage/prompt/settings/briefing).
AgentOrchestrator._spawn_container	method	roboco/runtime/orchestrator.py:2664	Run the Claude Code SDK container via docker with all mounts/env/manifest/cwd args; returns container id.
AgentOrchestrator._generate_mcp_config	method	roboco/runtime/orchestrator.py:2779	Write the per-agent MCP servers config (flow/do/git-readonly/optimal/docs) to disk and return the path; delegates the role-scoped extras to _append_role_scoped_mcp_servers.
AgentOrchestrator._append_role_scoped_mcp_servers	method	roboco/runtime/orchestrator.py:3541	Registers roboco-docs (documenter/PM/board roles), roboco-search (Board+PM roles, research_enabled), and playwright (fe-qa/ux-qa ONLY — role-gated via agent_role == "qa" + team in {frontend, ux_ui}, not image-gated, so ux-dev never sees it despite sharing agent-ux's image) — command: /app/scripts/playwright-mcp-entrypoint.sh, no args (the wrapper resolves the image's own baked chromium-headless-shell). Split out of _generate_mcp_config to keep it under the xenon complexity budget.
AgentOrchestrator._generate_composed_prompt	method	roboco/runtime/orchestrator.py:2946	Compose the spawn prompt (identity + task briefing + ambient conventions block + tool-load block) via compose_prompt.
AgentOrchestrator._resolve_conventions_ambient	method	roboco/runtime/orchestrator.py:2998	Resolve the in-scope projects for the ambient architectural-conventions block (single repo / product / ad-hoc cell map).
AgentOrchestrator._readiness_gate	method	roboco/runtime/orchestrator.py:3104	Pre-flight refusal: missing project/cell-map, missing AC, role/status mismatch, missing git token, bad task shape, unmet dependencies.
AgentOrchestrator._write_agent_briefing	method	roboco/runtime/orchestrator.py:3431	Fetch task + institutional memory + workflow state and render the per-agent briefing markdown at the cwd path.
AgentOrchestrator.start_intake_session	method	roboco/runtime/orchestrator.py:3612	Open the intake relay + schedule the guarded spawn of the single persistent intake container.
AgentOrchestrator._spawn_intake_container	method	roboco/runtime/orchestrator.py:3715	Spawn the intake container under _intake_spawn_lock: clone intake scope, build cmd, run, abort-if-shutdown, register instance, record usage session.
AgentOrchestrator._spawn_secretary_container	method	roboco/runtime/orchestrator.py:3918	Spawn the secretary container under _secretary_spawn_lock with authenticated identity env; same abort-if-shutdown shape as intake.
AgentOrchestrator._reap_idle_interactive_sessions	method	roboco/runtime/orchestrator.py:4038	Reap idle intake/secretary containers past interactive_idle_reap_seconds.
AgentOrchestrator._clone_intake_scope	method	roboco/runtime/orchestrator.py:4137	Clone the intake chat's project/product/multi-project scope into the intake workspace; returns cwd + cloned slug list.
AgentOrchestrator.stop_agent	method	roboco/runtime/orchestrator.py:4412	Stop a container; release_claim=True hands the claimed task back to the pool now (skips provider-parked); finalizes usage session.
AgentOrchestrator._release_stopped_agent_claim	method	roboco/runtime/orchestrator.py:4517	Idempotent unclaim_for_reaper on a stopped agent's task; best-effort, reaper backstops.
AgentOrchestrator._persist_respawn_record	method	roboco/runtime/orchestrator.py:4658	Atomic ON CONFLICT DO UPDATE upsert of one respawn_tracker row under _respawn_persist_lock so commits land in logical schedule order.
AgentOrchestrator._record_spawn_session	method	roboco/runtime/orchestrator.py:4804	Insert an agent_spawn_sessions row + pin its id on the instance for usage attribution.
AgentOrchestrator._finalize_spawn_session	method	roboco/runtime/orchestrator.py:5059	Resolve final token usage (Claude transcript or grok usage.json), update the spawn session row, publish USAGE_SNAPSHOT, evict instance.
AgentOrchestrator._sweep_token_snapshots	method	roboco/runtime/orchestrator.py:5262	Periodic live-usage snapshot sweep across active agents; finalizes stopped ones; budget-exceeded termination.
AgentOrchestrator._enforce_grok_cost_budget	method	roboco/runtime/orchestrator.py:4952	Kill live grok containers whose captured cost exceeds grok_max_cost_usd; release_claim=True.
AgentOrchestrator.restore_waiting_records	method	roboco/runtime/orchestrator.py:5479	Repopulate _waiting_records from the WaitingRecordTable at startup.
AgentOrchestrator.restore_respawn_tracker	method	roboco/runtime/orchestrator.py:5561	Repopulate _pm_respawn_tracker from respawn_tracker rows, re-stamping last_check/last_status to live values, evicting terminal/missing rows.
AgentOrchestrator._partition_respawn_rows	method	roboco/runtime/orchestrator.py:5515	Split restored respawn rows into restorable vs evict (terminal/missing task).
AgentOrchestrator.resolve_wait	method	roboco/runtime/orchestrator.py:5606	Resume a waiting agent: respawn FIRST then tear down the record only once a container launched (keeps record through a provider re-park bail).
AgentOrchestrator._health_loop	method	roboco/runtime/orchestrator.py:5728	Periodic _check_health pass over all instances.
AgentOrchestrator._sweeper_loop	method	roboco/runtime/orchestrator.py:5739	Periodic _run_sweep: superseded PRs, dangling images, transcript retention, budget exceeded.
AgentOrchestrator._check_health	method	roboco/runtime/orchestrator.py:6256	Per-agent docker inspect; on exit, route through _maybe_park_for_exit_error / _crash_retry_or_escalate / _handle_stopped_container.
AgentOrchestrator._inspect_container_state	method	roboco/runtime/orchestrator.py:6014	docker inspect with _DOCKER_INSPECT_TIMEOUT_SECONDS; returns (is_running, exit_code); per-agent failure skips that agent.
AgentOrchestrator._resolve_container_id	method	roboco/runtime/orchestrator.py:6047	Resolve a container id by name for re-adoption so _check_health sees the real id.
AgentOrchestrator._probe_gateway_health	method	roboco/runtime/orchestrator.py:6077	Out-of-band docker exec gateway-venv import probe for broken-but-alive agents; timed via _DOCKER_EXEC_TIMEOUT_SECONDS.
AgentOrchestrator._maybe_park_for_exit_error	method	roboco/runtime/orchestrator.py:6115	Detect session-limit/overload markers in dead container output + transcript tail; park provider instead of crash-retrying.
AgentOrchestrator._maybe_recover_broken_gateway	method	roboco/runtime/orchestrator.py:8689	Kill + evict a broken-but-alive agent past gateway_health_grace_seconds so it falls through to release + respawn.
AgentOrchestrator._strategy_engine_loop	method	roboco/runtime/orchestrator.py:6360	Default-off strategy engine tick loop (gated by strategy_engine_enabled).
AgentOrchestrator._external_pr_poll_loop	method	roboco/runtime/orchestrator.py:6383	Poll inbound external PRs for review (external_pr_enabled / internal_pr_enabled).
AgentOrchestrator._self_heal_loop	method	roboco/runtime/orchestrator.py:6411	Single-repo self-heal CI-watch tick loop (self_heal_enabled).
AgentOrchestrator._ci_watch_loop	method	roboco/runtime/orchestrator.py:6446	Multi-repo CI-watch tick loop (ci_watch_enabled); _load_ci_watch_set one per (repo, workflow).
AgentOrchestrator._dep_update_loop	method	roboco/runtime/orchestrator.py:6534	Dependency-update bot tick loop (dep_update_enabled); _load_dep_update_set one per (repo, command).
AgentOrchestrator._release_manager_loop	method	roboco/runtime/orchestrator.py:6576	Gated release-manager readiness sweep tick loop (release_manager_enabled).
AgentOrchestrator._projects_one_per_key	method	roboco/runtime/orchestrator.py:6665	Collapse projects to one canonical (by slug) per distinct key (repo / (repo,workflow) / (repo,command)).
AgentOrchestrator._rate_limit_probe_loop	method	roboco/runtime/orchestrator.py:6926	Probe parked providers every 30s; resume waiting agents on success; orphan-provider fallback for untracker-listed parks.
AgentOrchestrator._provider_spawn_parked	method	roboco/runtime/orchestrator.py:7016	True when the provider is currently rate-limited/overloaded parked (spawn short-circuit).
AgentOrchestrator._park_provider_unavailable	method	roboco/runtime/orchestrator.py:7172	Park an agent + provider: stop container, register rate_limit_lifted WaitingRecord, persist it, activate tracker.
AgentOrchestrator._park_grok_rate_limited	method	roboco/runtime/orchestrator.py:7233	Park a grok agent on xAI 429 (exit 75) with exponential re-park backoff within one episode.
AgentOrchestrator._park_grok_auth_unavailable	method	roboco/runtime/orchestrator.py:7268	Park a grok agent on missing/expired auth token (exit 78).
AgentOrchestrator._on_probe_failure	method	roboco/runtime/orchestrator.py:7350	Count failed probes; CEO-notify once at threshold; past _PROBE_GIVE_UP_THRESHOLD fall back to time-expiry optimism (clear park + resume).
AgentOrchestrator._readopt_running_agents	method	roboco/runtime/orchestrator.py:8547	At startup, re-adopt surviving containers into _instances as ACTIVE with real container ids; inert when nothing runs.
AgentOrchestrator._should_skip_live_reap	method	roboco/runtime/orchestrator.py:8750	Spare a live container from reaping UNLESS wedged (grok) or gateway-broken past grace (those kill+evict).
AgentOrchestrator._assignee_is_provider_parked	method	roboco/runtime/orchestrator.py:8527	True if a task's assignee is provider-parked; reaper skips it so the claim survives for probe-resume.
AgentOrchestrator._reap_with_service	method	roboco/runtime/orchestrator.py:8770	Inner stale-claim reaper: skip live (unless wedged/broken), skip provider-parked, unclaim_for_reaper the rest.
AgentOrchestrator._sandbox_available_services	method	roboco/runtime/orchestrator.py:2223	On-demand model (2026-07-08): availability probe only — which services this spawn's project opted into (sandbox_db_enabled + sandbox_services); [] if off/not-opted, byte-for-byte legacy path. No provisioning happens here anymore (see ensure_sandbox), so a spawn never fails on sandbox infra.
AgentOrchestrator.ensure_sandbox	method	roboco/runtime/orchestrator.py:2251	On-demand model: idempotent provision called by the request_sandbox do-verb. Cache hit (_sandbox_info, keyed by agent slug) covering the requested services returns the same creds; a miss provisions via SandboxProvisioner.provision (pre-clear tears down stale same-named containers) and caches the result. Evicted at teardown and by the janitor sweep; in-memory only — an orchestrator restart forgets it (next call re-provisions).
AgentOrchestrator._append_sandbox_marker_env	staticmethod	roboco/runtime/orchestrator.py:2846	On-demand model: replaces the old eager _append_sandbox_env — injects only a cheap informational marker (ROBOCO_SANDBOX_SERVICES_AVAILABLE=<csv>), never creds, naming the services request_sandbox() will provision on demand. Called INSTEAD OF _append_gate_env for an opted-in project's spawn.
AgentOrchestrator._sandbox_janitor_sweep	method	roboco/runtime/orchestrator.py:9426	Best-effort: remove sandbox containers whose owner agent is gone; rides the reaper tick, error-isolated.
AgentOrchestrator._x_mentions_poll_loop	method	roboco/runtime/orchestrator.py:7431	Default-off X-engine mentions-poll tick loop (x_engine_enabled); release-post drafts are event-driven, not from this loop.
AgentOrchestrator._run_x_mentions_cycle	method	roboco/runtime/orchestrator.py:7453	One mentions-poll pass: get_x_engine(db).run_cycle() + commit; testable without the sleep.
AgentOrchestrator._x_feature_spotlight_loop	method	roboco/runtime/orchestrator.py:7571	Default-off X-engine feature-spotlight tick loop (x_engine_enabled AND x_feature_spotlight_enabled); opens one held Head-of-Marketing exploration task per x_feature_spotlight_interval_seconds (default 3d).
AgentOrchestrator._run_x_feature_spotlight_cycle	method	roboco/runtime/orchestrator.py:7591	One feature-spotlight pass: get_x_engine(db).open_feature_spotlight_exploration() + commit; testable without the sleep.
AgentOrchestrator._roadmap_engine_loop	method	roboco/runtime/orchestrator.py:7462	Default-off board roadmap-engine tick loop (roadmap_engine_enabled); opens one held exploration cycle per interval.
AgentOrchestrator._run_roadmap_engine_cycle	method	roboco/runtime/orchestrator.py:7484	One roadmap-engine pass: get_roadmap_engine(db).run_cycle() + commit; testable without the sleep.
AgentOrchestrator._dispatch_roadmap_exploration	method	roboco/runtime/orchestrator.py:10284	One-shot Product-Owner spawn to author a themed roadmap cycle; bypasses the two-reviewer board-review-pair machinery (PO-solo in v1).
AgentOrchestrator._dispatch_feature_spotlight_exploration	method	roboco/runtime/orchestrator.py:10424	One-shot Head-of-Marketing spawn to investigate + call propose_feature_spotlight once; _dispatch_pm_work routes source=x_feature_exploration to it before the generic board-review check, mirroring the roadmap source's own early branch.
AgentOrchestrator._build_feature_spotlight_prompt	method	roboco/runtime/orchestrator.py:12827	Render the one-shot feature-spotlight exploration prompt (investigate CHANGELOG/flags/docs/charter/KB, call propose_feature_spotlight once, then i_am_idle).
AgentOrchestrator._dispatch_all_work	method	roboco/runtime/orchestrator.py:10906	Reset tick-handled set, reap stale claims, enforce grok budget, run all 18 dispatchers (added vault_curation_work) under one httpx client with per-dispatcher isolation.
AgentOrchestrator._dispatch_vault_curation_work	method	roboco/runtime/orchestrator.py:12057	Obsidian-vault root-completion hook (obsidian_vault_enabled): reads TaskService.list_completed_roots_pending_vault_curation and spawns the Auditor once per candidate via _maybe_spawn_vault_curation. Owns only this trigger — distinct from _dispatch_audit_work's scheduled sweeps.
AgentOrchestrator._maybe_spawn_vault_curation	method	roboco/runtime/orchestrator.py:12080	One-shot Auditor spawn for one completed root: _board_dispatched in-memory one-shot guard + a durable vault_curation_dispatched marker (survives a restart) before spawning WITHOUT a bound task_id (mirrors _dispatch_audit_work's alert spawn — the root is already completed, binding would trip the readiness gate) — the task id is named in the prompt, curate_vault takes it as an explicit argument.
AgentOrchestrator._vault_intake_loop	method	roboco/runtime/orchestrator.py:8106	Default-off tick loop (BOTH obsidian_vault_enabled AND vault_intake_enabled); calls _run_vault_intake_cycle → VaultIntakeEngine.run_cycle() every vault_intake_interval_seconds.
AgentOrchestrator._vault_janitor_loop	method	roboco/runtime/orchestrator.py:8142	V2: gated on obsidian_vault_enabled alone; ticks hourly (JANITOR_LOOP_INTERVAL_SECONDS, no config knob) calling _run_vault_janitor_cycle → VaultJanitor.run_cycle(), which itself only does real work when a RoboCo/_meta/.janitor_state.json state file says a sweep/report is actually due.
AgentOrchestrator._vault_kb_loop	method	roboco/runtime/orchestrator.py:8174	V2: gated on BOTH obsidian_vault_enabled AND vault_kb_enabled; ticks every vault_kb_interval_seconds (default 900) calling _run_vault_kb_cycle → VaultKBEngine.run_cycle(), embedding changed RoboCo/Notes notes into IndexType.VAULT_NOTES.
AgentOrchestrator._pending_claim_blocked	method	roboco/runtime/orchestrator.py:11586	Dispatch-time probe reusing TaskService.is_pending_claim_blocked (the exact claim-gate predicate — dependency OR sequence) so _route_unassigned_pm_task (called from _dispatch_pm_work per PENDING coordination-root task) can filter a doomed later-wave/sequence-held task before attempting the raw claim, instead of one failed claim per tick. Fails open (False) on any lookup error — the claim attempt itself is the safety net.
AgentOrchestrator._pm_respawn_should_gate	method	roboco/runtime/orchestrator.py:8915	Per-(slug,task) respawn circuit breaker; tracing_gap rule-following resets (bounded) + durable persist; CEO notify once when tripped.
AgentOrchestrator._handle_pm_assigned_task	method	roboco/runtime/orchestrator.py:9084	Spawn/respawn the PM for an assigned coordination root subject to the respawn gate.
AgentOrchestrator._AUTO_SUBMIT_VERB_BY_ROLE	ClassVar[dict]	roboco/runtime/orchestrator.py:10650	Wave-1 PR-gate turn cut: maps cell_pm -> (cell_pm, submit_up) and main_pm -> (main_pm, submit_root), the flow route+verb that assembles the parent's PR for each coordinator role.
AgentOrchestrator._auto_submit_target	method	roboco/runtime/orchestrator.py:10655	Resolve (role, route, verb, pm_uuid) for an auto-submittable parent; None when the parent is branchless coordination (no PR to assemble), the role has no submit verb, or no PM identity resolves. Unconditional otherwise — no flag (the pr_gate_auto_submit_enabled kill-switch was removed post-0.19.0).
AgentOrchestrator._try_auto_submit	method	roboco/runtime/orchestrator.py:10677	PR-gate turn cut: run the owning PM's submit_up/submit_root verb system-side via the internal flow API (no PM spawn) when every child of an assembled parent is terminal; True on gate acceptance (fires task.auto_submitted audit + _mark_task_handled), False on ANY refusal (branchless parent, unmapped role, gate rejection, or transport error) so the caller falls back to the classic PM closure spawn with the refusal reason threaded into its prompt.
AgentOrchestrator._closure_handled_without_pm	method	roboco/runtime/orchestrator.py:10740	Recover an auto-paused/blocked parent's status first (so the next actor lands on an actionable in_progress parent), then try _try_auto_submit; True skips the PM closure spawn entirely.
AgentOrchestrator._maybe_spawn_pm_closure	method	roboco/runtime/orchestrator.py:10768	If this parent task is ready for closure, try the system-side submit turn cut first (_closure_handled_without_pm); only spawn its PM when that declines (debounced via _is_recently_paused).
AgentOrchestrator._dispatch_dev_work	method	roboco/runtime/orchestrator.py:9733	Fetch pending/needs_revision/in_progress/claimed code tasks and route each through _dev_dispatch_one.
AgentOrchestrator._dev_dispatch_one	method	roboco/runtime/orchestrator.py:9861	Per-task dev dispatch: HITL skip, role/type mismatch guard, existing-owner respawn or pending spawn.
AgentOrchestrator._spawn_pending_dev	method	roboco/runtime/orchestrator.py:9800	Validate + spawn a dev for a pre-assigned pending task; applies the per-dev lane barrier _blocked_by_earlier_lane_sibling.
AgentOrchestrator._blocked_by_earlier_sibling	method	roboco/runtime/orchestrator.py:10183	MERGE barrier: hold a higher-sequence same-team sibling's review/merge until earlier siblings land (shared cell branch ordering).
AgentOrchestrator._blocked_by_earlier_lane_sibling	method	roboco/runtime/orchestrator.py:10234	Per-dev LANE barrier: hold a dev's higher-sequence code leaf until its own lower-sequence code siblings under the same parent are terminal.
AgentOrchestrator._dispatch_pm_review_work	method	roboco/runtime/orchestrator.py:10299	Dispatch awaiting_pm_review to cell/main PM; applies _blocked_by_earlier_sibling; human-role skip + respawn gate.
AgentOrchestrator._dispatch_a2a_work	method	roboco/runtime/orchestrator.py:10904	Spawn targets of unacknowledged a2a_request notifications; skips human-only roles (CEO/prompter/secretary).
AgentOrchestrator._dispatch_audit_work	method	roboco/runtime/orchestrator.py:12948	Spawn the auditor on reactive HIGH-priority ALERT notifications or on a scheduled sweep when ROBOCO_AUDIT_INTERVAL_SECONDS has elapsed and recent delivery activity exists.
AgentOrchestrator._build_dev_prompt	method	roboco/runtime/orchestrator.py:11053	Render the dev spawn prompt with workflow state + instructions.
is_unattributed_delivery_spawn	function	roboco/runtime/orchestrator.py:415	True when a delivery-role (developer/qa/documenter) spawn carries no task_id; warns on unattributed usage without noise from intentionally taskless roles.
AgentOrchestrator._flush_respawn_tracker	method	roboco/runtime/orchestrator.py:1105	Unbounded flush of the full in-memory PM-respawn snapshot called after _drain_bg_tasks in stop() so a deadline-cancelled fire-and-forget persist can't leave the durable count lagging.
AgentOrchestrator._confirm_resume_liveness	method	roboco/runtime/orchestrator.py:5798	Tears down a resumed agent's WaitingRecord only after confirming the container is still alive past _resume_confirm_delay (30s); a container that dies immediately keeps its record for the probe-resume orphan fallback.
AgentOrchestrator._new_strategy_loop_state	method	roboco/runtime/orchestrator.py:6538	Factory for _StrategyLoopState (consecutive-failure tracking for _strategy_engine_loop).
AgentOrchestrator._strategy_engine_cycle	method	roboco/runtime/orchestrator.py:6541	One strategy-engine pass; resets the failure counter on success and CEO-notifies once per failure episode past _STRATEGY_FAIL_CEO_NOTIFY_THRESHOLD.
AgentOrchestrator._notify_strategy_engine_failure	method	roboco/runtime/orchestrator.py:6568	Send one CEO alert that the strategy engine is persistently failing.
AgentOrchestrator._repo_key	method	roboco/runtime/orchestrator.py:6839	Normalized repo identity (delegates to converters.repo_key): strips .git, trailing slash, lowercases — shared by the poll-set collapse and the DB dedupe queries so ci-watch/dep-update use one normalization.
AgentOrchestrator._agent_holds_live_claim	method	roboco/runtime/orchestrator.py:8755	True when a slug owns a non-terminal task; used by _readopt_running_agents to skip zombie containers whose claim was already released.
AgentOrchestrator._stuck_claude_slug	method	roboco/runtime/orchestrator.py:8953	Slug of an ACTIVE non-GROK container holding a task with heartbeat stale past claude_stuck_kill_seconds; None when not eligible.
AgentOrchestrator._maybe_kill_stuck_claude	method	roboco/runtime/orchestrator.py:8988	Kill + evict a stuck non-GROK container past claude_stuck_kill_seconds so the reaper can release its task; called from _should_skip_live_reap.

Data Flow

Inputs: the dispatcher loop polls the orchestrator's own HTTP API (httpx AsyncClient with _system_api_headers) for tasks by status (pending/awaiting_qa/blocked/awaiting_pm_review/...) and for notifications (a2a_request/escalation/approval/audit); it also reads Docker state (docker inspect/exec/run) and Redis (RateLimitStateTracker) and the DB (TaskTable, WaitingRecordTable, RespawnTrackerTable, GatewayTriggerTable, agent_spawn_sessions, daily_usage_rollups) via get_session_factory / get_db_context. Control: _dispatcher_loop ticks every dispatcher_interval (30s) or on _dispatch_wake.set() from API routes (trigger_dispatch). Each tick: _reap_stale_claims -> _enforce_grok_cost_budget -> 17 dispatchers in order, each fetching tasks and calling spawn_agent (or _spawn_assigned_qa / _spawn_pending_dev / etc.). spawn_agent: readiness gate -> resolve git context -> provider-park pre-check (cheap, via _resolve_agent_route + _provider_spawn_parked) -> self._lock TOCTOU re-check -> _prepare_agent_spawn (writes settings/permissions/briefing/MCP config/manifest, ensures worktree via WorkspaceService.ensure_worktree_for_resume, ensures image) -> _launch_spawn -> _safe_spawn -> _spawn_container (docker run) or provider (grok). Outputs: registered AgentInstance in _instances, agent_spawn_sessions row pinned for usage, audit_log agent.spawned event, container running with mounted manifest + briefing + cwd at the worktree. On container exit: _check_health reads docker inspect, _maybe_park_for_exit_error parks the provider on session-limit/overload markers (registering a rate_limit_lifted WaitingRecord + persisting it + activating the tracker), else _crash_retry_or_escalate / _handle_stopped_container; _finalize_spawn_session resolves tokens from the Claude transcript (/usage/sync) or grok usage.json, updates daily_usage_rollups, publishes USAGE_SNAPSHOT to /ws/system. Recovery: _rate_limit_probe_loop probes parked providers every 30s, on success _on_probe_success clears the tracker + resume waiting agents via resolve_wait (respawn FIRST, delete record only after a real launch). Durable state: _persist_respawn_record / _persist_waiting_record write through to DB under respawn_persist_lock; restore*_at startup repopulates the in-memory registries. Callers: the FastAPI lifespan (roboco/api/bootstrap) constructs and starts/stops the singleton; API routes call trigger_dispatch, spawn_agent, stop_agent, start_intake_session, spawn_secretary_session, supersede_external_pr, get_status_summary.

Logical Tree

• AgentOrchestrator
  • Startup (start): restore WaitingRecord + respawn_tracker → reconcile orphan claims → _readopt_running_agents → launch background loops
  • Dispatch: _dispatch_all_work (reap → grok budget → 17 dispatchers under one httpx client) ticked by _dispatcher_loop (30s or _dispatch_wake.set()); includes _dispatch_audit_work for reactive auditor ALERTs and scheduled sweeps
  • Spawn: spawn_agent chokepoint → _readiness_gate → provider-park pre-check → _prepare_agent_spawn (worktree/permissions/briefing/MCP/manifest) → _safe_spawn → _spawn_container or GrokCliProvider
  • Health/reaper: _check_health (docker inspect) → _maybe_park_for_exit_error | _crash_retry_or_escalate | _handle_stopped_container; _reap_stale_claims via _should_skip_live_reap + _maybe_recover_broken_gateway
  • Rate-limit/overload park-and-probe: _park_provider_unavailable (+ grok 75/78 variants) → _rate_limit_probe_loop (30s) → _on_probe_success/_on_probe_failure → resolve_wait
  • Gateway-health: _probe_gateway_health → _gateway_broken_past_grace → _maybe_recover_broken_gateway (kill+evict)
  • Respawn tracker: _pm_respawn_should_gate → _persist_respawn_record (durable upsert) + restore_respawn_tracker at startup
  • PM closure / PR-gate turn cut: _maybe_spawn_pm_closure → _closure_handled_without_pm (recover paused/blocked status) → _try_auto_submit (system-side submit_up/submit_root via _AUTO_SUBMIT_VERB_BY_ROLE, unconditional — no flag); only a gate refusal falls through to an actual PM spawn, with the refusal reason threaded into its prompt
  • Default-off loops: _self_heal_loop, _ci_watch_loop, _dep_update_loop, _release_manager_loop, _strategy_engine_loop, _external_pr_poll_loop, _x_mentions_poll_loop, _roadmap_engine_loop
  • Interactive: start_intake_session / _spawn_intake_container / _spawn_secretary_container / _reap_idle_interactive_sessions
  • Shutdown (stop): cancel loops → stop_agent(release_claim=True) (skip provider-parked) → _drain_bg_tasks → _stopped

Dependencies

• Internal: roboco.config.settings; roboco.db.base.get_session_factory; tables RespawnTrackerTable, WaitingRecordTable, TaskTable, GatewayTriggerTable, agent_spawn_sessions, daily_usage_rollups; roboco.events.get_event_bus; roboco.llm.providers (ClaudeCodeProvider, GrokCliProvider, grok_auth); roboco.services.gateway (RateLimitStateTracker, role_config, claim_guards); WorkspaceService, TaskService, GitService, ConventionsService, SequencingService, CiWatchEngine, DepUpdateEngine, ReleaseManagerEngine, ReleaseReadinessService, MemoryDistiller; roboco.runtime.sandbox.SandboxProvisioner; roboco.services.x_engine.get_x_engine; roboco.services.roadmap_engine.get_roadmap_engine; roboco.runtime.compose_prompt; AGENT_IMAGES.
• External: Docker daemon (inspect/exec/run/rm); Redis; PostgreSQL+pgvector; Ollama; Claude Code SDK container image; grok CLI + ~/.grok/auth.json; the orchestrator's own HTTP API (/tasks, /notifications, /audit) via httpx with _system_api_headers.

Entry Points

• FastAPI lifespan start → AgentOrchestrator.start() (bootstrap constructs singleton).
• FastAPI lifespan shutdown → stop() (idempotent; bootstrap finally re-calls as safety net).
• _dispatcher_loop tick (30s or _dispatch_wake.set() from API trigger_dispatch), including _dispatch_audit_work for reactive auditor ALERTs and scheduled sweeps.
• _health_loop (per-instance inspect), _sweeper_loop (superseded PRs, dangling images, transcript retention, grok budget), _rate_limit_probe_loop (30s).
• Default-off loop ticks: self-heal / ci-watch / dep-update / release-manager / strategy / external-PR poll.
• API routes: spawn_agent, stop_agent, start_intake_session, spawn_secretary_session, supersede_external_pr, get_status_summary.

Config Flags

• ROBOCO_OVERLOAD_BREAK_ENABLED (default-on) — park on 529/500/503 + Claude session-limit 429.
• ROBOCO_GATEWAY_HEALTH_ENABLED (default-on) — broken-gateway probe + kill past grace.
• ROBOCO_SELF_HEAL_ENABLED + ROBOCO_SELF_HEAL_ORIGINATE_ENABLED — single-repo CI-watch loop.
• ROBOCO_CI_WATCH_ENABLED (+ _INTERVAL_SECONDS / _MAX_OPEN_TASKS / _MAX_PER_CYCLE / _DEFAULT_WORKFLOW) — multi-repo CI-watch.
• ROBOCO_DEP_UPDATE_ENABLED (+ _INTERVAL_SECONDS default 604800) — dependency-update bot.
• ROBOCO_RELEASE_MANAGER_ENABLED (+ _MIN_COMMITS / _INTERVAL_SECONDS) — gated release manager.
• ROBOCO_STRATEGY_ENGINE_ENABLED, ROBOCO_RESEARCH_ENABLED, ROBOCO_EXTERNAL_PR_REVIEW_ENABLED / ROBOCO_INTERNAL_PR_REVIEW_ENABLED — strategy / research / external-PR poll.
• ROBOCO_GROK_MAX_COST_USD — grok budget kill-switch; _GROK_RATE_LIMIT_EXIT_CODE=75, _GROK_AUTH_EXIT_CODE=78, _PROBE_GIVE_UP_THRESHOLD=30.
• ROBOCO_CLAUDE_STUCK_KILL_SECONDS (default 3600, min 600) — heartbeat-stale kill threshold for non-GROK agents; controls _maybe_kill_stuck_claude.
• ROBOCO_AUDIT_INTERVAL_SECONDS (default 21600) — cadence for scheduled auditor sweeps; 0 disables. Controls _dispatch_audit_work scheduled path.
• ROBOCO_DISPATCHER_INTERVAL_SECONDS (30), ROBOCO_INTERACTIVE_IDLE_REAP_SECONDS, ROBOCO_GROK_* backoff constants.
• ROBOCO_SANDBOX_DB_ENABLED (default off) — master switch for the sandboxed per-agent test DB/Redis/Mongo. On-demand model (2026-07-08): nothing is provisioned at spawn — _sandbox_available_services only probes+names the project's opted-in set (marker env), and ensure_sandbox provisions idempotently when an agent calls the request_sandbox do-verb (ContentActions.request_sandbox, gateway/content_actions.py). Teardown (_sandbox_janitor_sweep + every container-removal path) is unchanged. A project participates only when its sandbox_services column is also set. The service set is the SANDBOX_ENGINES registry (postgres / redis / mongo); adding an engine needs no orchestrator or env-emitter change.
• ROBOCO_DB_NETWORK_ISOLATED (default off; set by the compose topology that carries the roboco_data network) — suppresses the legacy _append_gate_env prod-creds injection when postgres/redis are unreachable from the agent mesh.
• ROBOCO_CLOUD_AUTH_ENABLED (+ _EMAIL/_PASSWORD/_SECRET/_COOKIE_MAX_AGE, default off) — cloud auth master switch; read by roboco.api.deps.get_agent_context/roboco.api.auth.*, not the orchestrator itself, but gates whether a spawned agent's own HMAC-token identity path is the sole non-CEO auth route.
• ROBOCO_X_ENGINE_ENABLED (+ _mentions_interval_seconds / _mentions_max_per_cycle / _mentions_min_engagement / _max_open_posts / _account_user_id / _request_timeout_seconds, default off) — gates _x_mentions_poll_loop.
• ROBOCO_ROADMAP_ENGINE_ENABLED (+ _interval_seconds default 604800 / _min_items_per_cycle / _max_items_per_cycle, default off) — gates _roadmap_engine_loop.
• ROBOCO_X_FEATURE_SPOTLIGHT_ENABLED (+ _interval_seconds default 259200/3d, default off, sub-switch of x_engine_enabled) — gates _x_feature_spotlight_loop.
• ROBOCO_FABLE_MODE_ENABLED (default off) — gates _fable_hook_groups (Claude-path hook install) and, via roboco/agents/factories/_base.py, the fable_doctrine_layer prompt layer; off = byte-for-byte unchanged spawn path.
• No flag — the PR-gate turn cut is unconditional: when every child of an assembled parent is terminal, _try_auto_submit always runs the owning PM's submit_up/submit_root gate system-side instead of spawning the PM for that turn; a gate rejection (freshness/integrity/AC-coverage/race) falls back to the classic PM closure spawn (the sole safety net), with the reason threaded into the PM's closure prompt. The pr_gate_auto_submit_enabled kill-switch that gated this through 0.19.0 has been removed.
• ROBOCO_OBSIDIAN_VAULT_ENABLED (default off; both compose files set true) — gates _dispatch_vault_curation_work (the vault-curation Auditor-spawn trigger), _vault_intake_loop's outer check, and (V2) _vault_janitor_loop's sole gate. ROBOCO_VAULT_INTAKE_ENABLED (default off; both compose files set true) — the _vault_intake_loop's own switch, consulted only when the vault master switch is also on. V2: ROBOCO_VAULT_ARCHIVE_DAYS (default 30) / ROBOCO_VAULT_REPORT_ENABLED (default true) tune the janitor's archival pass and weekly report, both folded into _vault_janitor_loop with no separate loop. ROBOCO_VAULT_KB_ENABLED (+ _KB_DIRS default RoboCo/Notes / _KB_INTERVAL_SECONDS default 900, default off; NAS compose sets it true, registry compose leaves it false) — the second, independent switch _vault_kb_loop checks alongside the vault master switch.
• No flag — _pending_claim_blocked (the dependency/sequence claim-gate prefilter) is unconditional, mirroring TaskService.claim's own always-on sequence gate; it is a pure dispatch-time optimization (fails open on lookup error) with no behavior change vs. attempting and failing the claim.

Gotchas

• Respawn-tracker rows are restored at startup and re-stamped to live values; terminal/missing-task rows are evicted, so a stale row can't gate a fresh task. The upsert is race-free but fire-and-forget persists are ordered by _respawn_persist_lock acquisition (= schedule order); a stale persist resolving after a fresh one would otherwise re-burn the strike threshold on restart.
• _instances is reconciled-from-Docker at startup (_readopt_running_agents), NOT persisted — a surviving container is re-adopted as ACTIVE with its real container id so _check_health (which skips container_id is None) sees it.
• Session-limit 429 parking reads the Claude Code SDK transcript tail, not docker logs — _maybe_park_for_exit_error detects the marker in the dead container output + transcript; docker logs alone miss it.
• Grok exit 78 (auth missing/expired) parks with kind="auth_missing"; grok_auth.refresh_if_stale mints a fresh token per dispatch tick, and the entrypoint backstop refuses start instead of hanging at an interactive login prompt.
• Human-only roles (CEO/prompter/secretary) are never spawned: spawn_agent refuses and _dispatch_a2a_work skips notification targets that are human roles — a2a requests to them are silently dropped (no delivery lifecycle).
• _dispatch_a2a_work's _fetch_notifications(..., "a2a_request") sets pending_ack_only=True, so it only ever sees a2a_request rows with requires_ack=True. A2A_REQUEST's ACK_REQUIRED_BY_TYPE default is False, so this dispatcher was structurally dead for every a2a_request row until wave 3 (2026-07-17): A2AService._maybe_wake_ceo_recipient (docs/map/a2a-audit-journal-permissions.md) is the only producer that opts a row in, via a per-row requires_ack override on NotificationService.send_a2a_notification/CreateNotificationParams — and only for a CEO-authored DM to a read_a2a-capable recipient. Ordinary agent-to-agent dm and the legacy create_a2a_notification path still create requires_ack=False rows invisible to this poll.
• Fire-and-forget _bg_tasks (respawn_tracker upserts, audit rows) are drained at shutdown under _SHUTDOWN_DRAIN_TIMEOUT_SECONDS; past the deadline they're cancelled, so a cancelled persist degrades to in-memory-only (can only suppress a spawn, never manufacture one).
• Budget-kill (_enforce_grok_cost_budget) finalizes the spawn session BEFORE popping the instance so captured usage/cost isn't lost; the reaper then releases the freed claim.
• _should_skip_live_reap short-circuits like the original and: when not live, none of the three kill checks is awaited. The three kill paths are: _maybe_kill_wedged_grok (grok idle TTL), _maybe_kill_stuck_claude (non-GROK agent stuck past claude_stuck_kill_seconds, default 3600s), and _maybe_recover_broken_gateway. A Claude agent stuck in a genuine verb loop (still firing gateway verbs, so heartbeat advances) remains spared — the stuck-claude TTL only catches heartbeat-stale containers.
• Tests/helpers that construct AgentOrchestrator via AgentOrchestrator.__new__(AgentOrchestrator) to bypass __init__ rely on __new__ pre-initializing _instances, _last_audit_spawn_at, and _notification_spawn_at. Any refactor that moves those initializations out of __new__ or adds new instance attributes read by _dispatch_audit_work/_is_agent_active/notification-cooldown paths without also pre-initializing them will re-break those helpers. __init__ must continue to re-initialize _instances so normal construction is unaffected.
• _auto_submit_target requires BOTH branch_name and project_id on the parent — a MegaTask umbrella (branchless coordination) always fails this check and falls through to the classic PM closure spawn, which is correct (an umbrella assembles no PR) but means the turn cut never applies to the top of a MegaTask tree, only its root-subtasks.

Drift from CLAUDE.md

• None material. The orchestrator runs the six default-off loops CLAUDE.md lists (self-heal, CI-watch, dep-update, release-manager, strategy, external-PR poll); ROBOCO_ORG_MEMORY_ENABLED has no orchestrator loop (capture/retrieval live in TaskService/EvidenceRepo, by design). Respawn-tracker durability (migration 051), _instances reconciled-from-Docker, and the park-and-probe shape all match the prose.

Changes Since Baseline

git log fd10cc862c..HEAD -- roboco/runtime/orchestrator.py (+1370/-361):

• 15effce0 Chore: 141 Gaps fill-in (#283) — bulk gap closure; orchestrator touchups across spawn/readiness/dispatch paths.
• 3aff6e04 Chore: Close gaps (#285) — MegaTask per-cell project map: _ambient_projects_for_task + _resolve_subtask_project fan-out generalized to first-distinct-project-of-map-or-product; multi-cell root-subtask intake/cloning wired.

Post-snapshot updates (since 2026-06-29):

• 536bbb64 Chore/all/logical gaps sweep (#286) — Cluster O hardening: _confirm_resume_liveness fixes the park/probe revival race (#71); _flush_respawn_tracker called unbounded after _drain_bg_tasks in stop() to fix re-burn on restart (#74); _maybe_kill_stuck_claude + _stuck_claude_slug + _agent_holds_live_claim added to kill non-GROK agents stuck past claude_stuck_kill_seconds (#73); _should_skip_live_reap now chains three kill checks (grok-wedged, stuck-claude, gateway-broken); _strategy_engine_loop refactored into _strategy_engine_cycle + _notify_strategy_engine_failure with consecutive-failure CEO alert (#193); is_unattributed_delivery_spawn + _TASKLESS_SPAWN_SUSPECT_ROLES warn on delivery-role spawns with no task_id (#11); _repo_key delegates to converters.repo_key for git_url normalization; spawn_agent human-role guard uses is_human_only_role() from foundation.identity; _ensure_worktree_before_spawn now heals a vanished clone root via WorkspaceService._is_workspace_healthy + ensure_workspace before ensure_worktree_self_heal.
• d34bc1a7 ci-watch/dep-update dedupe: _repo_key normalizes git_url (strip .git, trailing slash, lowercase) and empty-string workflow treated as default so the DB dedupe and the orchestrator poll-set collapse agree.
• 7be10057 Agent image: stop baking VIRTUAL_ENV=/app/.venv — comment in _generate_mcp_config updated to drop the stale VIRTUAL_ENV reference.
• 6b441e42 Converters: InvalidIdentifierError now caught explicitly in _release_stopped_agent_claim with a structured warning log instead of a silent broad-except return.
• d1cf6ecb Wave 1: PR-gate turn cut, task search, trace timestamps, Secretary edits + e2e scenarios 2–3 (#295) — adds config.pr_gate_auto_submit_enabled (default True) + _AUTO_SUBMIT_VERB_BY_ROLE / _auto_submit_target / _try_auto_submit / _closure_handled_without_pm, wired into _maybe_spawn_pm_closure so an assembled, all-children-terminal parent is submitted to the PR gate system-side instead of always spawning the PM for that turn; fires a new task.auto_submitted audit event.
• v0.18.0 (2026-07-04): Fable mode — _fable_hook_groups (orchestrator.py:1414) appends 5 vendored hook scripts after RoboCo's own inside _generate_agent_settings, gated by fable_mode_enabled (default off). X feature-spotlight — _x_feature_spotlight_loop/_run_x_feature_spotlight_cycle (mirrors _x_mentions_poll_loop's shape) + _dispatch_feature_spotlight_exploration/_build_feature_spotlight_prompt (mirrors the roadmap engine's one-shot board-solo dispatch) open a held Head-of-Marketing exploration task every x_feature_spotlight_interval_seconds, gated by x_feature_spotlight_enabled (sub-switch of x_engine_enabled, both default off).
• 89b68786 (PR #502, 2026-07-13): Added AgentOrchestrator.__new__ to pre-initialize _instances for __init__-bypass construction used by e2e helpers. Fixes AttributeError in _dispatch_audit_work when the reactive/scheduled auditor dispatch path calls _is_agent_active on a bare-__new__ orchestrator. __init__ still re-initializes _instances, so normal construction is unchanged.
• 49b93248 (PR #504, 2026-07-13): Extended AgentOrchestrator.__new__ to also pre-initialize _last_audit_spawn_at and _notification_spawn_at. Hardens the __init__-bypass construction path against AttributeError when the auditor-dispatch and notification-cooldown paths read those attributes; the existing _fresh_orchestrator helper's explicit initialization is now defensive rather than required. __init__ still re-initializes the registries for normal construction.

Regression Risks

Title	File:Line	Claim	Severity
Park/probe revival race	orchestrator.py:5798	resolve_wait respawns FIRST and deletes the WaitingRecord only after a real launch; if the respawn succeeds but the container dies immediately the record is gone and the task strands until the reaper's TTL. FIXED (536bbb64): _confirm_resume_liveness keeps the record past the launch and tears it down only once the agent is confirmed alive past 30s; a dead container keeps its record for the probe-resume orphan fallback.	medium resolved
Gateway-health over-reap of live containers	orchestrator.py:8689	_maybe_recover_broken_gateway kills a live container past gateway_health_grace_seconds; a transient-but-recurring probe miss (None clears the mark, but a flaky false-broken streak) could kill a healthy agent mid-long-edit.	medium-high
Readopt liveness false-positive	orchestrator.py:8796	_readopt_running_agents registers ACTIVE for any running roboco-agent-{slug} container at startup, including a zombie from a prior orchestrator that already released the claim — blocks re-spawn until the stale container is noticed. FIXED (536bbb64): _agent_holds_live_claim is now called for each running container; a container whose slug holds no non-terminal task is identified as a zombie and skipped (not registered ACTIVE) so the spawn gate can immediately re-dispatch.	medium resolved
Stalled-claim reaper live-skip blind spot	orchestrator.py:9078	_should_skip_live_reap spares any live container that is neither grok-wedged nor gateway-broken; a Claude agent alive but stuck in a non-verb loop keeps its claim forever. MITIGATED (536bbb64): _maybe_kill_stuck_claude added as a third kill check — a non-GROK container with heartbeat stale past claude_stuck_kill_seconds (default 3600s) is now killed + evicted. Residual: a Claude agent stuck in a long verb loop (heartbeat still advancing via gateway calls) remains spared.	medium low
Budget-kill / shutdown claim release timing	orchestrator.py:1105	stop() calls stop_agent(release_claim=True) for every instance then _drain_bg_tasks; a respawn persist cancelled by the drain deadline leaves the durable count lagging in-memory (re-burn on next restart). FIXED (536bbb64): _flush_respawn_tracker is called unbounded AFTER the bounded drain in stop(), so a drain-cancelled persist is overwritten by the flush before the process exits.	medium resolved
Fire-and-forget _bg_tasks persist ordering	orchestrator.py:4658	_persist_respawn_record upsert is race-free but commits land in lock-acquisition order; if the lock isn't the first await at a future edit, a stale count could again win the durable row.	low
Grok re-park retry_after back-off reset	orchestrator.py:7233	_park_grok_rate_limited resets _grok_repark_count to 0 after a 25-min episode gap; a single slow re-park keeps the default 60s cycle — recovery latency is fine, but a borderline gap can flatten backoff mid-window.	low
Human-only-role spawn skip drops a2a	orchestrator.py:10904	_dispatch_a2a_work skips human-only notification targets; a future a2a request that expects a human-side action (CEO sign-off relay) is silently dropped, not surfaced.	medium
Respawn-tracker durable restore evicts too eagerly	orchestrator.py:5561	restore_respawn_tracker evicts rows whose task is terminal/missing; a task that transitioned terminal mid-restart (race) drops its strike count, so a still-wedged PM respawns from 0.	low
Reaper live-skip falls back to Docker on registry miss	orchestrator.py:8597	_assignee_container_running returns False on any inspect error (no docker binary / test ctx), so in a real-Docker failure the reaper releases a live agent's claim — mitigated by the instance-registry authoritative path.	low

Health

The orchestrator is the most behaviour-critical module in RoboCo and it shows: every race-prone path (respawn-tracker upsert, park-and-probe resume, readopt liveness, broken-gateway kill) carries an explicit docstring naming the live incident it prevents and the failure mode it degrades to, and the durable-state paths mirror the hardened WaitingRecord pattern (best-effort, can only suppress a spawn). Post-536bbb64, four previously medium risks are resolved: the park/probe revival race, the readopt zombie registration, the shutdown respawn-tracker re-burn, and the non-GROK stuck-agent blind spot (now caught by _maybe_kill_stuck_claude past 3600s). The residual exposure is the strategy-engine failure alert threshold (a misconfigured assess() could still silently fail for up to _STRATEGY_FAIL_CEO_NOTIFY_THRESHOLD ticks before surfacing) and the restart-window race where a terminal transition landing mid-restore drops a strike count. Net: integrity is high and well-instrumented.
