Slice: api-routes-schemas

Purpose

The FastAPI surface of RoboCo: every HTTP route under roboco/api/routes/ (the operator/panel api/* CRUD + dashboard/orchestrator/a2a/live bridges) and the agent-gateway api/v1/flow/* (intent verbs) + api/v1/do/* (content tools), with Pydantic request/response schemas under roboco/api/schemas/. Routes are thin handlers that resolve services via Depends and return typed responses; all agent-gateway verbs funnel through the Choreographer.

Data Flow

Request hits nginx (port 3000) -> FastAPI app (api/app.py) registers routers under /api/* plus /api/v1/flow/* and /api/v1/do/*. Middleware chain (CorrelationId -> RequestLogging) attaches a correlation ID and logs; exception handlers intercept 422/HTTP/RobocoError/generic. Router-level Depends resolves DbSession + agent context (HMAC-verified from X-Agent-* headers) and, on agent-gateway routes, the role guard. The thin handler pulls a service via Depends (TaskService, Choreographer, ContentActions, GitService, OptimalService, ReleaseProposalService...) and returns a typed Pydantic response; flow/do verbs return the Choreographer Envelope via envelope_to_response. SSE (EventSourceResponse) is used for live-chat streams and a2a send-stream.

Dependencies

• FastAPI + sse-starlette (SSE), pydantic v2.
• roboco/api/deps.py — shared deps (DbSession, agent context, HMAC, orchestrator).
• roboco/api/middleware.py — exception handlers + correlation/log middleware.
• roboco/services/* — TaskService, GitService, OptimalService, AgentOrchestrator, Choreographer, ContentActions, ReleaseProposalService, PrompterService, SecretaryService, MetricsService, XPostService, XCredentialsService, RoadmapService, etc.
• roboco/api/auth/* (auth_backend, get_user_manager, resolve_session_user, mount_cloud_auth) — cloud auth, consumed by deps.get_agent_context's dual-path and the WS panel-token gate.
• roboco/foundation/identity.py (Role) + roboco/agents_config.py (verify_agent_token, CEO_AGENT_ID).
• roboco/api/websocket.py + websocket_bridge.py (WS event forwarding).

Entry Points

• roboco/api/app.py create_app() builds the FastAPI app, mounts all routers under /api (prefix) + /ws (WS router).
• roboco/api/routes/v1/_role_dep.py is imported by every flow router + do + a2a for HMAC/role guards and envelope_to_response.
• roboco/api/routes/orchestrator.py router constructed with dependencies=[Depends(_require_ceo)] (router-wide CEO gate).

Config Flags

• Auth-gate mode: _auth_required() (env-driven; HMAC mandatory in prod-ish, optional in dev) — api/deps.py.
• Feature-flag routes are inert when their backing engine is off: release.py (ROBOCO_RELEASE_MANAGER_ENABLED), prompter_live.py MegaTask batch, optimal.py learnings (ROBOCO_ORG_MEMORY_ENABLED), research.py (ROBOCO_RESEARCH_ENABLED), provider.py grok/self-hosted (ROBOCO_GROK / self-hosted), CI-watch/dep-update originate elsewhere but surface via orchestrator/tasks.

Gotchas

• do + a2a routers are token-only (any authenticated role), not role-asserted — any signed agent can call any content verb; service-layer scope is the only gate.
• request_validation_handler scrubs secrets from the log but the 422 response body echoes the client's submission unchanged (comment explicit) — secrets can still leak to the caller if the caller is not the legitimate owner.
• SSE live-chat bridges open one session per query/stream and rely on require_panel_token (CEO HMAC injected by nginx); a missing/invalid token in dev mode is tolerated (_auth_required() false) — prod must arm it.
• StrList BeforeValidator is load-bearing: without it the Claude SDK's XML-nested list input crashes i_will_plan/delegate with 422 (MegaTask memory Bug 3).
• orchestrator.py and release.py use two different _require_ceo implementations (HMAC header vs agent.role==CEO from context) — keep their semantics aligned.
• WS endpoints live on /ws/* (separate router in websocket.py), not under /api; the bridge subscribes to StreamEventBus and forwards per resource-id.
• /api/tasks PATCH is not a single admin surface: _pm_editor_scope (tasks.py:256) routes cell_pm/main_pm to a content-only allowlist (_PM_LIGHTER_UPDATE_FIELDS: title/description/acceptance_criteria/priority, zero status changes) enforced by _enforce_pm_lighter_fields (tasks.py:278), while CEO/Board/Auditor keep the unrestricted admin bypass; a cell_pm editing a task outside its own team 403s before the field check even runs.
• GET /api/tasks/summary and GET /api/secretary/tasks both call the same TaskService.search_tasks (ILIKE title/description + id-prefix) but through different auth (agent-context view-scope vs Secretary-or-CEO role check) and different response shapes (trimmed TaskSummaryResponse vs a hand-built dict list) — don't assume one route's pagination/limit semantics apply to the other.

Drift from CLAUDE.md

• CLAUDE.md lists pr_pass/pr_fail under pr_reviewer verbs and the in-path gate; code matches (flow_pr_reviewer.py exposes claim_gate_review, pr_pass, pr_fail). No drift found.
• CLAUDE.md says agent comms use say/dm/notify via do_server; code matches (v1/do.py exposes all three). No drift.
• CLAUDE.md lists sync_branch as a developer verb; present in flow_dev.py:125. No drift.
• CLAUDE.md's verb table omits flow_pr_reviewer.post_pr_review (external PR comment) — present in code; additive, not contradictory.
• None material.

Changes Since Baseline

git log fd10cc86..HEAD -- roboco/api/routes/ roboco/api/schemas/:

• 15effce0 Chore: 141 Gaps fill-in (#283) — broad route/schema hardening pass (the only logic-touching commit in range at the time this section was last refreshed).

Post-snapshot: many further commits touch this slice (536bbb64, df87fcf0, a8cb2470, 0ca9d91b, cfde4369, 0f1ed3cc, 1c87a4e4, and the three below) — only the wave-1/2/2c ones relevant to this pass are itemized; a full re-audit of the intervening route/schema history is still owed.

• d1cf6ecb Wave 1 (#295) — adds GET /api/tasks/summary?q= search (TaskService.search_tasks), GET /api/prompter/live/{id}/search-tasks (intake memory), GET /api/secretary/tasks?q= (Secretary task-by-name lookup), and the Secretary edit directive action.
• da563487 Wave 2 (#297) — adds the CEO-only /api/a2a/chat/admin/{conversations,conversations/{id}/messages,conversations/{id}/reply} routes (_require_ceo) for the A2A live view + reply-as-CEO.
• 876e19b3 Wave 2c (#298) — adds /api/a2a/chat/admin/pairs (the switchboard, same _require_ceo gate); tightens /api/tasks PATCH so cell/main PM roles get a content-only field allowlist instead of the unrestricted CEO/Board/Auditor admin bypass (_pm_editor_scope / _enforce_pm_lighter_fields, roboco/api/routes/tasks.py:256,278) — closes an over-permission hole where PM identities could edit any-team tasks via the ASSIGN-holding bypass.

Regression Risks

Title	File:Line	Claim	Severity
do/a2a any-role token gate	v1/do.py:43, a2a.py:114	require_any_authenticated_agent only verifies HMAC + that the agent exists; it does NOT assert the role matches the verb's intended role family — a QA-signed token could call do/commit, or any agent could call the participant-scoped a2a routes (send/conversations) for a pair it has no policy access to (only the gateway's can_a2a_direct/validate_a2a_access matrix, a service-layer check, stops it). Service-layer scope is the sole guard on these paths; a missed service check = privilege escape. Correction: the /chat/admin/* routes (org-wide live view + reply-as-CEO) are NOT on this gate — they carry their own router-level _require_ceo guard, added in wave 2 (da563487) and extended to /chat/admin/pairs in wave 2c (876e19b3); a non-CEO agent 403s before reaching the service layer on those.	High
422 response echoes secrets	middleware.py:407	_scrub_secrets redacts only the log body; the JSON response still contains body with the caller's original secret fields. A 422 on git_token/api_key returns the secret back to the client (and to any MITM/log of the response).	High
orchestrator CEO gate vs release CEO gate divergence	orchestrator.py:37 vs release.py:32	Two independent _require_ceo implementations: orchestrator uses HMAC header verification, release uses agent.role == CEO from CurrentAgentContext. If one path's HMAC/context resolution drifts, the two CEO surfaces enforce different identities.	Medium
SSE transport errors swallowed	prompter_live.py:122, secretary_live.py:61, a2a.py:195	EventSourceResponse streams run long-lived; a Choreographer/orchestrator raise mid-stream is caught by contextlib suppress but can drop the stream silently without a terminal event to the panel.	Medium
Cross-repo PR collision via /api/work-sessions/{id}/pr/merge	work_session.py:259	PR merge by global pr_number (no project_id scoping in the route signature) — the same class of cross-repo collision already fixed in cell_pm_complete could recur if this endpoint is wired to merge.	Medium
Dashboard/metrics endpoints role-gating	dashboard.py:58+	/ceo, /auditor, /scorecard/* rely on CurrentAgentContext but the route-level gating is weak (no explicit require_pm_or_above); a non-CEO agent calling /dashboard/ceo is filtered only by service-layer logic, not the router.	Medium
WS panel-token vs agent-token dual gate	websocket.py / deps.py	/ws/* endpoints use a WS-specific _require_panel_token for panel streams but agent-id keying for /ws/agents/{id}; mismatched HMAC secret rotation between the two could grant panel read of agent streams or vice-versa.	Low-Med
flow i_will_plan StrList crash recurrence	schemas/v1/flow.py:20	If a new LLM-authored list[str] field is added to a flow schema without StrList, the SDK XML-nesting crash reappears (silent 422 loop). Reviewer-only by inspection.	Low-Med

Health

The route layer is thin, consistently organized (one router per domain, one schema file per router), and the agent-gateway HMAC guard is centralized in _role_dep.py + deps.py. Main risks are the any-role do/a2a gate (relies on service-layer scope), the 422 response echoing secrets, and the two divergent CEO guards — all addressable without structural change. SSE live-chat streams are the fragile transport path.
