Integration prompt — ai-ahu-chatbot: close the last X-User-Id gaps (internal staff surface + query-time embeddings)

Paste into a Claude Code session inside the ai-ahu-chatbot repo. Follow-up to e12ae68 (per-actor X-User-Id + per-turn trace id) — that closed the PUBLIC path; this closes the two gaps the live audit trail still shows. No gateway change; additive/dormant-safe.

Why (grounded in the live observatory data, last 3 days)

The per-actor security analytics is live and now resolves public chat to real users. Two attribution gaps remain, measured from ai_calls:

surface / op real user id blank
public / chat 42 11
internal / chat 2 66
internal / embed 0 16
public / embed 0 3

So: the internal (staff) surface is essentially unattributed — which is the higher-value target (insider/misuse detection is about staff, not anonymous public), and embeddings carry no actor on either surface. The mechanism to fix both already exists — this is extending its coverage, not building anew.

The existing seam (from e12ae68 — reuse it, don't reinvent)

dash/gateway.py: a user_id_var ContextVar, seeded by RequestIdMiddleware from the incoming X-User-Id, injected into every agno/embedder call by GatewayHeaders/gateway_default_headers(). Staff identity = an opaque non-PII HMAC of the verified-JWT email (lib/auth/actor-id.ts), injected server-side by the dash-proxy (overriding any client value). Public = req.sessionId.

Gap 1 — internal staff chat is unattributed (66/68 blank)

e12ae68 injected the staff HMAC actor id for the data-dash path (apps/internal-agent/dash/…, "Generasi Laporan Data via NLP"). But the general internal assistant surface ("Asisten Panduan Layanan AHU") — and any other internal-web → internal-agent / internal-web → gateway LLM egress that isn't the dash-proxy — does not seed user_id_var, so those calls reach the gateway with no X-User-Id.

  • Find every internal egress path that produces engine=ahu-chatbot, surface=internal audit events (start from the internal chat/assistant route(s) and their agent calls; the 66 blank calls are chat ops, so trace the staff assistant request flow).
  • Seed the same staff HMAC actor id (actor-id.ts, from the verified staff JWT) into user_id_var on those paths — reuse the dash-proxy injection pattern; do not invent a second identity source. Server-side derived, never client-trusted, non-PII.
  • Result: internal chat attributes to the staff member (as an opaque stable id), exactly like the data-dash path already does.

Gap 2 — embeddings carry no actor

Every operation=embed event is blank. Decide per call-path, don't blanket-fix:
- Query-time retrieval embeddings (an embedding computed to serve a live user/staff request) SHOULD carry that request's actor — they're part of the user's footprint (same rule as the RAG /search identity work). If user_id_var isn't seeded in the embedder's execution context for these, seed it (the embedder already reads gateway_default_headers() → user_id_var; the gap is the var being empty when the embedder runs).
- Offline reingest / knowledge-refresh embeddings (no user in scope) are legitimately actor-less — but make them an honest machine actor rather than ambiguous blank: seed user_id_var with system:reingest (mirrors the OCR engine's system:<stage> convention) so the audit distinguishes "batch machine work" from "we failed to attribute a user."
- The deciding question per path: is there an authenticated human on this request? Human → their id; no human → system:reingest.

Dormancy + verification

  • Additive X-* only; with the gateway unflipped the headers are ignored — behavior unchanged.
  • Tests: internal assistant chat call carries the staff HMAC X-User-Id; a query-time embedding carries the requesting actor; a reingest embedding carries system:reingest; none carry PII.
  • Post-deploy check (observatory): re-run the table above — internal/chat should now be dominated by real ids, embed should split into real-actor (query-time) + system:reingest (batch), and the Security view's internal actors should resolve to staff ids instead of "unattributed".

Report back

Which internal egress paths were seeding-gapped and how you closed them; the query-time-vs-reingest split you found for embeddings and how each is now tagged; confirmation the staff id is the existing actor-id.ts HMAC (not a new source); and the refreshed attribution numbers.
