Two things: the new desktop API (chimera/api) got its first adversarial review, and the frontend's types are now generated from the backend so they can't drift.

Fixed — 8 findings from the 17th adversarial review (2 security-relevant)

  • 🔒 .env write couldn't be injected via a value. The config-write endpoint allowlisted the key but not the value — a newline in a value could inject extra .env lines (e.g. a provider key). Values with \r/\n are now rejected.
  • 🔒 Read endpoints are guarded when a token is set. With CHIMERA_SERVER_TOKEN configured, transcripts / memory / config now require the token too (not just mutations). The token is injected into the SPA only for a loopback client, so the local browser authenticates while a remotely-exposed instance never hands the secret to remote clients.
  • The token guard reads settings fresh, so a token set at runtime takes effect immediately.
  • Concurrent turns on the same session serialize behind a per-session lock (no more racing the transcript).
  • The live-session cache is LRU-bounded (no unbounded growth from random session ids).
  • memory search k is clamped; an unknown /api/* path returns 404 instead of the SPA; the in-flight-cost-on-disconnect limit is documented.

Clean: SSE auth, secret masking, session/SPA path-traversal, project HITL (no token spend on approve/deny).

Added

  • The frontend API types are generated from the backend's OpenAPI schema (python -m chimera.api.schema_dump → npm run gen:api), and a CI job fails if they drift — a backend model change becomes a TypeScript build error, not a silent runtime mismatch.

Gate: 1482 passed / 4 skipped, mypy + ruff green; frontend build clean; OpenAPI types in sync.

Upgrade: `pip install --upgrade 'chimera-agent[desktop]'`
