Address security-review finding: the host-side legal-chat-service was
binding 0.0.0.0:8770 with no authentication. The service spawns the
claude CLI, whose tool set includes Bash + Edit — so an unauthenticated
/chat/start is effectively RCE. Oracle Cloud's security list closes the
port externally, but defense-in-depth requires two independent layers:
1. Bind defaults to 10.0.1.1 (docker0 bridge gateway). Reachable from
containers on docker bridges (the legal-ai container has a route via
the coolify network), invisible to anything outside the host. The
--host flag is still configurable for local-dev (127.0.0.1) or
special-case deployments, but 0.0.0.0 is explicitly discouraged in
the docstring.
2. /chat/start requires Authorization: Bearer <LEGAL_CHAT_SHARED_SECRET>.
The secret is loaded from /home/chaim/.legal-chat-service.env (chmod
600, off-repo) by the pm2 ecosystem and mirrored as a Coolify env
var so the FastAPI chat_proxy sends a matching header. hmac.compare_digest
prevents timing oracles. /health stays unauthenticated (static OK,
no subprocess) so the FastAPI proxy can probe liveness without the
secret.
The service refuses to start if LEGAL_CHAT_SHARED_SECRET is empty or
shorter than 24 chars — no silent fallback to an open mode.
When the Infisical MCP comes back, migrate the secret into the vault
at /_GUIDELINES per the project secrets policy.

Six-phase upgrade of /training from a read-only dashboard into a full
Style Studio for managing Daphna's style corpus.
- Upload Sheet on /training: file → proofread preview → commit (no more
CLI-only `upload-training` skill).
- Rich corpus metadata: GET /api/training/corpus returns summary, outcome,
key_principles, page_count, parties (regex), legal_citation, lessons_count.
PATCH endpoint for chair edits. CorpusDetailDrawer with 4 tabs (details
/content/lessons/patterns) replaces the bare table row.
- LLM metadata enrichment: style_metadata_extractor + MCP tools
(style_corpus_enrich, style_corpus_pending_enrichment) fill summary
/outcome/key_principles via claude_session (free, host-side).
- Per-decision lessons: new decision_lessons table + 4 REST endpoints +
LessonsTab in drawer; hermes-curator now auto-posts findings as
decision_lessons(source=curator).
- Curator Portrait tab: prompt rendered with link to Gitea, recent
curator findings, style_analyzer training prompts, propose-change
form that writes proposals to data/curator-proposals/ for manual
chair review (no auto-mutation of the agent file).
- Style chat tab: SSE-streamed conversations with the style agent.
New host-side pm2 service (legal-chat-service, port 8770) wraps
claude CLI with stream-json + --resume continuation; FastAPI proxies
via host.docker.internal. Zero API cost — uses chaim's claude.ai
subscription. chat_conversations + chat_messages persist history.
Architecture: keeps the existing rule that claude_session only runs
on the host (not the container). The new legal-chat-service is the
canonical bridge between the container and the local CLI for the chat
feature; everything else (upload, metadata, lessons) stays within the
container's existing capabilities.
Audit script (scripts/audit_training_corpus.py) included for verifying
which corpus rows still need enrichment.
