Phase 3.1 closes the cross-process gap the Phase 3 smoke surfaced —
streaming events (msg_start/thinking/delta/complete/curated) flow
from agent-runner → chamber via valkey pub/sub rather than the
SQLite bridge (too high-volume + ephemeral for the DB).
New service: `althing-valkey` (stock `valkey/valkey:8-alpine`).
Internal-only — no exposed port, no volume. chamber + agent-runner
reach via docker DNS at `valkey:6379` on the compose default
network. healthcheck via `valkey-cli ping` (5s interval). chamber
+ agent-runner gain `depends_on: valkey: service_healthy` so the
bridge is up before either side starts publishing or subscribing.
Forseti unchanged — never publishes Phase 3 events.
Operational properties (per forseti's deployment notes):
- Mixed-state safe at every step. Missing valkey.url config key
→ chamber + runner stay on v3.0 / Phase 2 equivalent paths.
- Backward path is single config-key delete + restart.
- streaming_enabled: true (set on agent-runner 2026-05-17) is
unaffected by this change.
README's services table + playbook header + verify section all
extended to reflect the four-service shape. Forseti's contract
at vh/althing:docs/contracts/phase3_1_valkey_bridge.contract.md
carries the wire-protocol spec.
Phase 2 daemon added to the althing-chamber stack per forseti's request
(vh/althing@5cd088a..ad1d025). Polls floor_grants WHERE consumed_at IS
NULL AND agents.driver='worldtree', claims via atomic UPDATE, calls
Worldtree's conversation API, posts the response back through the bus
as a broadcast.
Shape matches the existing forseti daemon:
- Same ${ALTHING_IMAGE} (the binary is already in [project.scripts]
as of ad1d025)
- command: ["althing-agent-runner"]
- Same shared SQLite bind-mount at /app/data
- No port, no healthcheck (CLI doesn't expose one; same liveness
story as forseti)
Safe to enable preemptively per forseti — when no driver=worldtree
handles are declared in config, the runner sleeps at
poll_interval_seconds. Multi-instance safe via the atomic claim
primitive (no flock needed).
Compose top comment, README "Services in this stack" table, playbook
header + verify steps all extended to reflect the three-service
shape. Will land on ana-docker on vh/althing's next push (compose
deployed via the elway playbook's upload step; image already carries
the binary).
Two-service compose (chamber + forseti sidecar daemon) sharing a single
SQLite store via bind-mount under /opt/docker/conf/althing-chamber/data.
eventbus.bridge_from_db is the cross-process glue — forseti's commits
reach chamber's SSE subscribers via the bridge.
Pattern matches task-board's build-on-host deploy:
- elway playbook clones vh/althing into /opt/docker/build/
- docker build -t althing-chamber:local . (no registry)
- playbook uploads compose + seeds .env one-time, brings both
services up, polls /health
- Gitea Actions workflow lives in vh/althing; reference copy here.
Internal tooling — host port 7881 (chamber's default of 7878 collides
with task-board). LAN-direct, no Traefik. Container always listens on
8000 internally.
Scaffold will fail to bring the chamber container up healthy until
galdrabok-side commits land:
- Dockerfile at vh/althing repo root (two-stage: uv-bookworm-slim
build → python:3.12-slim runtime, locked per open_questions §2
of the v1 contract).
- GET /health endpoint on the chamber app (200, no DB read).
- ALTHING_BIND / ALTHING_PORT env-var support in
core.cli.chamber_serve / core.chamber.cli (env > config.yaml >
defaults precedence).
