* [fastapi-guard] Phase 1a: gated config flags for the HTTP security layer Adds the ROBOCO_GUARD_* settings (all default-off / secure-default) for the upcoming fastapi-guard 7.2.0 hardening — guard_enabled (master switch), guard_fail_secure (fail-closed default; NAS overrides to false), guard_telemetry_enabled + guard_agent_api_key + guard_project_id (guard-agent telemetry, opt-in), guard_emergency + guard_emergency_whitelist (lockdown kill switch). Inert until consumed: nothing reads them yet, so the request path is unchanged. Foundation for v0.16.0. * [fastapi-guard] Phase 1b: security foundation module + gated wiring Add fastapi-guard 7.2.0 + guard-core 3.3.0 (bare, unpinned) and roboco/security.py: - build_security_config() from settings — behind-nginx real-IP (trusted_proxies + trust_x_forwarded_proto), HSTS/CSP headers, threat-ban + 404-sweep rules, redis-backed state, exclude_paths (/ws + health + docs), env-driven enforce_https, fail_secure (secure default), emergency lockdown, guard-agent telemetry (opt-in), passive-mode calibration switch. - guard_deco singleton (SecurityDecorator) for per-route decorators (Phase 2+). - Three custom content validators guard's WAF can't cover: prompt-injection / role-override, secret-exfil / credential-in-body, internal-SSRF. - apply_guard(app) + guarded_lifespan() wired into create_app AFTER settings. guard_passive_mode config flag added. Entirely gated by ROBOCO_GUARD_ENABLED (default off): create_app mounts nothing and returns the unchanged app when off (verified). make quality GREEN (cov 95.32%, pip-audit clean, import-linter 2/0). 12 new unit tests. * [fastapi-guard] Phase 2: critical-path decorators Apply guard decorators to the highest-value endpoints (metadata-only; enforced only when the middleware is mounted, so no-op while ROBOCO_GUARD_ENABLED is off): - provider keys (ollama/grok/self-hosted writes): strict rate_limit + max_request_size + block_clouds (no datacenter IP should touch secret writes). - settings write + release approve/reject (CEO-gated): strict rate_limit. - intake chat (prompter start/messages/events): rate_limit + max_request_size + custom_validation(prompt_injection_validator) — the prompt-facing free-text ingress gets the injection/role-override/secret-exfil content scan. make quality GREEN (cov 95.32%, contracts 2/0). App builds with guard off, decorators inert (verified). * [fastapi-guard] Phase 3: wide decorator coverage across ingress + sensitive routes Targeted-wide application (metadata-only; no-op until ROBOCO_GUARD_ENABLED). The global SecurityMiddleware already rate-limits + WAF-scans every request, so this adds the custom content validators on free-text ingress + tight limits on sensitive ops (not blanket per-route rate_limit on reads): - agent gateway do verbs (note/say/commit/dm/pitch/progress/draft_playbook/...): rate_limit + max_request_size + custom_validation(secret_exfil or prompt_injection). - a2a message/send + chat writes: rate_limit + size + prompt_injection. - optimal/RAG (kb/search, rag/query, mentor/ask, errors/decisions/standards/ learnings): prompt_injection on searches, secret_exfil on record writes; docs index → internal_ssrf. - tasks: create/update → prompt_injection; QA/doc/PM transitions → secret_exfil; CEO-gated verbs → tight rate_limit. - secretary chat → prompt_injection; research → internal_ssrf; orchestrator spawn/mutations → rate_limit; git ops + flow verbs → tight rate_limit. Pure GET/reads left to the global middleware. Applied via a Sonnet workflow, then verified: app builds with guard off (decorators inert), make quality GREEN (cov 95.37%, contracts 2/0). Decoy/honeypot-path surface deferred (needs verified guard ban-API integration — not rushed). * [fastapi-guard] Phase 5: arm the NAS composes in passive/log-only mode Arm ROBOCO_GUARD_ENABLED=true + ROBOCO_GUARD_PASSIVE_MODE=true + ROBOCO_GUARD_FAIL_SECURE=false on the two NAS composes (docker-compose.yaml + .yml). Passive = guard mounts and logs what it WOULD block but blocks nothing, so the next NAS deploy calibrates against real traffic; flip PASSIVE_MODE off after the false-positive review to enforce. fail_secure=false keeps a guard-internal error from 500ing the personal deploy. The registry (user-facing) compose is deliberately left unarmed so its published default stays conservative. Phase 4 (passive calibration) is the operational step this enables. * feat(security): Phase 3b — full-arsenal per-route guard enrichment Stack the applicable guard decorators per surface instead of the minimal rate_limit/max_request_size/custom_validation triad: content_type_filter on every JSON-body write, honeypot_detection form-traps on human-facing POSTs, block_clouds on key-writes + CEO release ops, behavior_analysis runaway-rate rules on the agent flow/do verbs, suspicious_detection + usage_monitor on the sensitive surfaces. Nine distinct decorators now applied thoughtfully per endpoint. All metadata-only — no-op while ROBOCO_GUARD_ENABLED is off. * fix(a2a): permit PR reviewer to deliver gate verdicts to the owning PM can_a2a_direct had no pr_reviewer rule, so a reviewer (team=board, or a cell team) fell through to the cell-member path and was cross-cell-denied when the in-path gate delivered a pr_fail change-request to main-pm (or a cross-cell cell-pm): "Cannot A2A main-pm ... Ask None to coordinate with None". The delivery is best-effort, so pr_fail still transitioned but the verdict never reached the owning PM — the blind-re-submit signal-gap the pr_fail fix closes. Add an explicit pr_reviewer handler: it may A2A only cell_pm / main_pm (its sole comms surface — everything else it posts on the PR itself), with a matching route hint. The cell reviewers kept same-team access by coincidence; this scopes every reviewer to PM-only, the correct model, with no other A2A caller affected. Refresh uv.lock to the current resolution. * feat(models): adopt Claude Sonnet 5 as the sonnet tier Point the 'sonnet' alias at claude-sonnet-5 (MODEL_MAP) and give pr_reviewer its own opus tier in ROLE_MODEL_MAP — it was falling through to the sonnet default, and the role gates untrusted external/fork PRs plus root→master, which warrants opus. Price claude-sonnet-5 at the promotional 33% off Sonnet 4.6 ($2.01 / $10.05, cache 0.201 / 0.5025) through 2026-08-31 via a dedicated pricing fragment that beats the bare 'sonnet' alias; revert to full rate when the promo ends. Bare 'sonnet' stays full-rate as a conservative fallback (prod prices the resolved claude-sonnet-5 id from the transcript). Update the model docs and the billing / usage / manifest / spawn tests. * feat(security): calibrate the guard WAF for RoboCo traffic + document the layer The first end-to-end run of the fastapi-guard layer showed active enforcement would block ~50% of legitimate agent traffic — RoboCo request bodies are code, SQL, diffs, file paths, HTML, and URLs, which the stock signature WAF reads as attacks. build_security_config now excludes RoboCo's free-text top-level body fields (derived from the real request models, including the free-form container fields whose nested prose is stringified and scanned) from WAF scanning, dropping the active-mode false-positive rate to zero while keeping the WAF on every non-excluded (id/enum/slug/branch) field and leaving the prompt-injection / secret-exfil / internal-SSRF validators — which run independently of the exclusion — fully in force. enable_penetration_detection is made explicit. Only excluded_detection_body_fields is reliable on guard 7.2.1: the per-route categories knob is bypassed for JSON bodies, and the body scanner excludes top-level keys only (scanning str(value) of every non-excluded field), so free-form container fields must be excluded wholesale. Adds tests/unit/test_security_middleware.py — the first end-to-end exercise of the middleware (mounts it, drives guard's lifespan, fires real requests): proves passive mode is log-only, active mode does not false-positive on realistic agent payloads, threats are still blocked inside excluded fields, and the WAF still fires on non-excluded fields. Docs: CHANGELOG (Unreleased); a user-facing Optional-subsystems page + nav + env reference for the HTTP security layer; the agent-facing RAG corpus (what it is + why a request could be blocked); and the roboco mapping (api-core-websocket / deployment-tooling / _complete_map). * feat(security): Surface N — scanner honeytrap (guard /api auto-ban + nginx edge-drop) Turns scanner probes against the scanner, in two layers matched to where traffic lands. Behind nginx only /api, /ws, /health, /ready reach the orchestrator, so guard can only see (and ban) scanner probes on those paths; the classic root probes (/.env, /wp-login.php, /phpmyadmin, /.git/config) hit the panel. So: - build_security_config's threat_ban_config gains recon / sensitive_file / cms_probing categories. A scanner probing those fingerprints on an /api path is detected on the URL-path scan; repeated probes from one IP trip an adaptive per-IP auto-ban (redis-backed, 24h). Only bans in active mode (passive logs the recon hit) and needs redis (the 24h ban exceeds the in-memory cap). The spec's decoy-route file is redundant — the WAF url-path scan bans regardless of a registered route — so it is intentionally omitted. - docker/nginx.conf drops the classic root scanner paths at the edge with 444 (connection closed, no response) before they reach the panel, anchored to known scanner fingerprints so /.well-known and every real panel/API route are untouched. Always on, independent of ROBOCO_GUARD_ENABLED. Tests: 2 unit (the exclusion set + the scanner-ban categories are present) and 2 integration (a decoy path is blocked in active mode, passes in passive). The nginx regex was validated against 15 scanner + 19 legit paths (0 false positives). Docs: CHANGELOG, the HTTP-security page, the roboco mapping, and the agent-facing RAG corpus. * Token optimization — per-role observability, compute policy, spawn preflight (#291) * test(models): lock the sonnet→claude-sonnet-5 MODEL_MAP invariant * feat(usage): surface cache tokens + cache_hit_rate in usage breakdowns * feat(usage): add per-role usage breakdown endpoint * feat(usage): add spawn-waste signal (per-role unproductive rate + respawn strikes) * feat(panel): surface per-role cost/cache + spawn-waste on the metrics page * feat(routing): Phase 2 per-role compute policy — qa→haiku, main_pm→sonnet, per-role effort env mechanism (default-inert) * feat(orchestrator): Phase 3 flag-gated spawn preflight — refuse non-gateway delivery roles (respawn-forever guard) * chore(compose): arm ROBOCO_SPAWN_PREFLIGHT_ENABLED on the NAS composes * docs: per-role usage observability, per-role compute policy, and spawn preflight --------- Co-authored-by: Renn F <rennf93@users.noreply.github.com> * fix(panel): pin outputFileTracingRoot so the standalone build isn't broken by stray lockfiles * feat(routing): populate ROLE_EFFORT_MAP + wire the verified --effort flag (cell_pm/board/auditor to medium) * feat(gateway): omit empty context_briefing sections (Phase 4 payload compaction) * refactor(orchestrator): extract spawn chokepoint guards to restore xenon rank B on spawn_agent --------- Co-authored-by: Renn F <rennf93@users.noreply.github.com>

HTTP Security Guard
What It Is
RoboCo's HTTP request layer is protected by fastapi-guard (v7.2.1), implemented in roboco/security.py and wired into the app in roboco/api/app.py's create_app.
Enable/Disable
| Variable | Default | Effect |
|---|---|---|
ROBOCO_GUARD_ENABLED |
false |
Master switch. Off = completely inert — no middleware is mounted, the request path is entirely unchanged, and nothing is logged or blocked. |
ROBOCO_GUARD_PASSIVE_MODE |
see below | When the guard is enabled, controls whether it blocks matching requests or only logs them. |
As of 2026-07-01 the guard is built on the feature/fastapi-guard-hardening branch, gated off by default, and wherever it is enabled at all it is running in passive/log-only mode — so no agent request is currently being blocked by it anywhere.
When Armed
With ROBOCO_GUARD_ENABLED=true, a SecurityMiddleware sits outermost in the middleware stack, and per-route decorators add rate limits, request-size caps, content-type filters, a signature-based WAF (detects SQL injection, XSS, path traversal, and suspicious URL patterns), security response headers, cloud-provider/honeypot checks, and an emergency lockdown switch.
On top of those generic checks, three RoboCo-specific custom validators run against request bodies:
| Validator | Blocks |
|---|---|
| Prompt-injection detection | Bodies attempting to inject instructions |
| Secret-exfil detection | Bodies carrying literal credential-shaped strings (e.g. sk-ant-..., ghp_..., postgres connection URLs) or phrasing like "reveal your api keys" |
| Internal-SSRF detection | Fetch-type bodies targeting internal/metadata hosts (e.g. 169.254.169.254, roboco-* internal service hostnames) |
Enforcement Posture
ROBOCO_GUARD_PASSIVE_MODE decides what happens on a match: true (passive) detects and logs only, and never blocks a request — this is how the NAS production deploy is armed today. false (enforce) actually blocks the matching request.
A blocked request gets a generic 400 or 403 response — no rule or signature detail is returned, so the response body can't be used to fingerprint what tripped the guard.
WAF Calibration for Agent Traffic
Agent traffic legitimately carries code, SQL, diffs, file paths, HTML snippets, and URLs — for example inside note / commit / say bodies. To avoid false positives, the free-text body fields on those routes are excluded from WAF signature scanning via excluded_detection_body_fields in build_security_config, so normal code/SQL/diff/HTML payloads from agents are not flagged by the WAF layer.
The three custom validators above are not covered by that exclusion — they scan those same bodies regardless of the WAF exclusion. See docs/rag/troubleshooting/blocked-http-requests.md for what this means in practice and what not to put in a request body.
Scanner Auto-Ban
A separate layer targets automated scanners (not agents — agents run on Docker-internal IPs). Repeated probes to scanner fingerprints on /api paths (recon/sensitive_file/cms_probing categories) trip a per-IP auto-ban in active mode, and nginx drops the classic root scanner paths (/.env, /wp-login.php, /.git/config, …) at the edge with 444. This does not affect legitimate agent traffic to the gateway verbs.
