# POST /api/v1/{context_id}/chat

`POST /api/v1/{context_id}/chat`

Phase 7.5 — Spectron-as-agent chat endpoint. Stores the user message via /facts, retrieves context via the unified /query router, calls the configured LLM provider, stores the assistant response via /facts, and emits a response_trace. Set `stream=true` for SSE.

## Path parameters

- `context_id` string, required

## Request body

- ChatRequestJson
  - `bypassCache` boolean — Phase 7.6 — when `true` skips the tier-2 response cache and forces a fresh tier-3 call. Defaults to `false`.
  - `labels` string[] — Descriptive labels for rows the chat persists.
  - `message` string, required
  - `model` string, nullable
  - `scopes` array[] — A DNF scope selector: an OR of conjunctive clauses. Each clause is an array of scope paths, ALL of which a reader must cover (AND); the outer array is the OR. E.g. [["team/a"],["team/b","clearance/secret"]] means team/a OR (team/b AND clearance/secret). Empty means unscoped (the caller's default region). A bare string is also accepted as a singleton clause.
    - string[]
  - `sessionId` string, nullable
  - `stream` boolean
