Phase 4 — everything needed to flip the Mission Key-Grant feature on
safely per deployment. No new behaviour; purely operational plumbing.
- PUBLIC_AI_MISSION_GRANTS feature flag (default off). hooks.server.ts
injects window.__PUBLIC_AI_MISSION_GRANTS__, api/config.ts exposes
isMissionGrantsEnabled(). Grant UI (dialog + status box) and the
Workbench "Datenzugriff" tab both hide when the flag is off.
- PUBLIC_MANA_AI_URL added to the injection set so the webapp can reach
the new audit endpoint from production.
- Prometheus alerts (new mana_ai_alerts group):
- ManaAIServiceDown (warning, 2m)
- ManaAIGrantScopeViolation (critical, 0m) — MUST stay at 0; any
increment pages immediately
- ManaAIGrantSkipsHigh (warning, 15m) — flags keypair drift
- ManaAIPlannerParseFailures (warning, 10m) — prompt/LLM drift
- Runbook in docs/plans/ai-mission-key-grant.md: initial keypair gen,
leak-response procedure (rotate + invalidate all grants + audit),
scope-violation triage.
- User-facing doc in apps/docs security.mdx: new "AI Mission Grants"
section with the three hard constraints (ZK users blocked, scope
changes invalidate cryptographically, revocation is one click) plus
an honest threat-model comparison column showing where grants shift
the tradeoff.
Rollout remaining (not code): generate keypair on Mac Mini, provision
MANA_AI_PRIVATE_KEY_PEM + MANA_AI_PUBLIC_KEY_PEM via Docker secrets,
flip PUBLIC_AI_MISSION_GRANTS=true starting with till-only.

Foundation for Phase 2+ of the Mission Key-Grant flow: lets mana-ai
execute missions that depend on encrypted inputs (notes/tasks/events/
journal/kontext) without needing an open browser tab. Opt-in per
mission, Zero-Knowledge users excluded.
- Canonical HKDF-SHA256 derivation (scope-bound via tables + recordIds
in the HKDF info string → scope changes invalidate the grant
cryptographically, not just via a runtime check)
- Mission.grant field on the shared Mission type
- Golden snapshot + drift-guard test so webapp wrap path and mana-auth
wrap endpoint can't silently diverge
- Ideas backlog at docs/future/AI_AGENTS_IDEAS.md
- Full rollout plan at docs/plans/ai-mission-key-grant.md
- COMPANION_BRAIN_ARCHITECTURE.md §21 captures the flow + privacy
guarantees + non-goals
