feat(fleet): F4 Phase 2a — Matrix CS-API connector client + factory (#616)
Implements the Matrix connector behind the F4 abstraction (stacked on #617).
Speaks the Matrix client-server API directly over HTTPS (injectable fetch, no
SDK) so it is homeserver-agnostic (Conduit default, Synapse alt).

- MatrixConnector implements OrchestratorConnector:
  - send  → PUT /_matrix/client/v3/rooms/{room}/send/m.room.message/{txn}
            (thread-aware via m.thread relation), returns event_id.
  - subscribe → /sync long-poll loop driven by the pure parseSyncResponse
            (skips the orchestrator's own echoes; carries threadId).
  - health → /_matrix/client/versions (reachable) + /account/whoami (authed).
- Pure helpers buildMessageBody + parseSyncResponse → send/receive unit-testable.
- registerMatrixConnector(env) registers the factory; the access token comes from
  MATRIX_ACCESS_TOKEN, never the roster.

Verified: 13 Matrix + 7 registry = 20 connector tests green; tsc/eslint/prettier
clean. Still a self-contained connectors/ module (no fleet.ts changes).

Stacked on #617 (F4 Phase 1). Merge order: #617 -> this; rebases onto main after.

F4 — Orchestrator chat connector + Matrix (#616)

  • Issue: #616 · Branch: feat/f4-matrix-connector (off main; independent of #615) · Doctrine: north-star #613.

Phase 1 (this PR) — abstraction + scaffold

  • src/fleet/connectors/types.ts: OrchestratorConnector (send/subscribe/health) + message/config types; thread-aware via optional threadId; DEFAULT_CONNECTOR_KIND=tmux.
  • src/fleet/connectors/registry.ts: extensible factory registry; resolveConnectorKind (defaults tmux, back-compat); createConnector throws ConnectorNotImplementedError until Phase 2 registers factories.
  • roster.schema.json: optional connector block (tmux|discord|matrix; matrix homeserver/user/room; secrets via env, never roster).
  • Design doc docs/fleet/f4-matrix-connector.md: interface, config, Matrix CS-API mapping, Conduit-default infra, phasing.
  • No fleet.ts changes → self-contained, zero conflict with stacked #615.

Verification

  • 7 connector tests green; tsc/eslint/prettier/sanitize clean; schema valid JSON.

Phase 2+ (follow-ups, in the doc)

Matrix CS-API client (fetch send/sync/health) + factory; init/configure connector-selection UX + roster-parse wiring; systemd launch wiring; Conduit deploy guide; first-party Mosaic Discord (threads) as a connector.

Phase 2a (feat/f4-matrix-client, stacked on #617) — Matrix CS-API client

  • src/fleet/connectors/matrix.ts: MatrixConnector implements OrchestratorConnector over the Matrix client-server API (injectable fetch, no SDK). send → PUT m.room.message (thread-aware); subscribe → /sync long-poll loop using the pure parseSyncResponse; health → /versions + /whoami. registerMatrixConnector(env) registers the factory (token from MATRIX_ACCESS_TOKEN, never roster).
  • Pure helpers buildMessageBody + parseSyncResponse make send/receive unit-testable.
  • 13 Matrix tests + 7 registry = 20 connector tests green; tsc/eslint/prettier clean.
  • Remaining Phase 2: init/configure connector-selection UX + roster-parse wiring (touches fleet.ts — after #615); systemd launch wiring; Conduit deploy guide.
