Refresh Current-state repo line after committing the Phase 3 spec

docs/spark-control-integration.md: the SSH command contract (status via
docker inspect; restart via docker restart; update via git fetch + reset
--hard origin/master + docker compose up -d --build) plus the one-time
conversion of the Spark's ~/matrix-bridge to a Gitea clone. No bot code
change. Update source = git-pull-from-Gitea; rides Spark Control's existing
SSH into spark-32d0 (no new key). Corrected the infra note: Spark is on the
LAN with the Start9/Gitea host, so Spark->Gitea resolves directly.

+- **WireGuard (`starttunnel`) for Mac↔Spark:** Mac `10.59.211.5`; Spark (`spark-32d0`, user `modelo`)
+  `10.59.211.6`. The Mac↔Spark seam runs over WireGuard (not the Mac's LAN subnet). The Spark *is*
+  on the LAN, same as the Start9 host (`immense-voyage`) — so Spark→Gitea (`immense-voyage.local:59916`)
+  resolves and works directly.
+- **Spark → Mac:** SSH alias `mac-bridge` → the Mac as user `macpro`, dedicated key
+  (`~/.ssh/id_ed25519` on the Spark, in the Mac's `authorized_keys`). The Spark host's `~/.ssh/config` needs `IdentitiesOnly yes` because a
+  `Host *` rule shadows the default key; the container regenerates a clean config from `config.toml [mac]`.
+- **Mac → Spark:** no authorized key — direct Mac-initiated Spark ops stay owner-run. (This is *not*
+  what Phase 3 closes: Spark Control already has its own SSH channel into `spark-32d0`, so its
+  status/update/restart buttons ride that, not a Mac→Spark key.)
+- **Matrix:** homeserver `https://matrix.gilliam.ai` (StartOS Synapse), bot `@agent:matrix.gilliam.ai`,
+  device `matrix-bridge-bot`. The bot reuses the stored access token (`.env`) — never re-logs in
+  (avoids device churn). No E2EE (D9); bot↔Synapse is clearnet TLS, softening D9's WireGuard-only rationale.
+- **Mac env:** `claude` lives in `~/.local/bin`, on PATH only via `~/.zprofile` — so every wrapper is
+  `#!/bin/zsh -l` (a non-login SSH shell loads neither `.zprofile` nor `.zshrc`).
+- **Interactive-launch prereqs:** Mac logged into its desktop + a one-time Terminal Automation grant
+  (TCC). If the grant resets, a launch stalls — the bot reports it fail-loud rather than hanging.
+- **Folder-trust gate:** the first `claude` run in a repo it has never been opened in stalls on the
+  trust prompt; already-used repos are trusted. Affects unattended interactive launches and ask mode.

-  message text free of `'`/`"`* — the typed SSH command line breaks on them (PS2 `>` hang); the
-  Phase-1 bot avoids this via `shlex.quote`.
-- **Phase 0 — PROVEN / DONE (2026-06-15).** N=3 by-hand runs succeeded across multiple rooms
-  (recap, spark-control, premier-gunner): each opened a Terminal in the right repo, started `claude`
-  on the message, and pushed a drivable session to the phone. The deterministic core holds.
-  Added session naming: `launch-claude.sh` now runs `claude -n "<repo> - <topic>"` (topic from the
-  message, overridable via `$MB_SESSION_NAME`) so Remote Control's phone index is readable —
-  confirmed `-n` drives the phone app's conversation label.
-- **Next: Phase 1 — the matrix-nio bot.** Container on the Spark, logged in as `@agent` (token in
-  `.env`), listening in the 9 mapped rooms; on a message it runs `ssh mac-bridge gui-launch.sh
-  <repo_dir> <message>` (built with `shlex.quote`) and reports failures back to the room. See
-  ROADMAP Phase 1 (also: bake key+config into the image, curated `$MB_SESSION_NAME` topic, fail-loud).

+| Fact | Value |
+|---|---|
+| Host | `spark-32d0` (`10.59.211.6` on WireGuard), user **`modelo`** |
+| Project dir | `/home/modelo/matrix-bridge` (`~/matrix-bridge` for modelo) |
+| Compose service | `bot` |
+| Container name | `matrix-bridge` (fixed via `container_name:`) |
+| Image | `matrix-bridge-bot` |
+| Lifecycle | host networking, `restart: unless-stopped` (survives Spark reboot) |
+| Secrets | `.env`, `config.toml` — **gitignored**, live only on the Spark, never in git |
+
+Spark Control already SSHes into `spark-32d0`, so these ride the existing channel — **no new
+key needed.** All commands below assume they run **as `modelo`** (owner of the dir, member of
+the `docker` group). If Spark Control's channel connects as a different user, wrap each command
+in `sudo -iu modelo bash -lc '<command>'` — running `git` in modelo's repo as root trips git's
+"dubious ownership" guard, so don't skip this.
+
+---
+
+## One-time prerequisites (owner, not Spark Control dev)
+
+The bot dir on the Spark was originally populated by `scp` of loose files. To make
+git-pull-based updates work it must become a git clone of the Gitea repo **without disturbing
+the gitignored secrets** (`.env`, `config.toml`). Because those two files are gitignored,
+`git reset --hard` never touches them — so we can convert the existing dir in place.
+
+**0a. Confirm the Spark can reach + authenticate to Gitea (fail loud here, not at first button press):**
+
+```sh
+git ls-remote ssh://git@immense-voyage.local:59916/grant/matrix-bridge.git >/dev/null \
+  && echo "gitea reachable" || echo "FIX gitea access first"
+```
+
+The Spark is on the same LAN as the Start9 host running Gitea, so `immense-voyage.local`
+resolves directly — this should just work. If it doesn't, the only likely gap is a key
+authorized for read on the Gitea repo available to `modelo` (deploy key or existing key).
+Don't proceed until `git ls-remote` succeeds.
+
+**0b. Convert `~/matrix-bridge` to a clone tracking `master` (run as `modelo`):**
+
+```sh
+cd /home/modelo/matrix-bridge
+git init -b master
+git remote add origin ssh://git@immense-voyage.local:59916/grant/matrix-bridge.git
+git fetch origin
+git reset --hard origin/master          # secrets are gitignored → untouched
+git branch --set-upstream-to=origin/master master
+```
+
+Verify the secrets survived and the container still comes up clean:
+
+```sh
+ls -la /home/modelo/matrix-bridge/.env /home/modelo/matrix-bridge/config.toml   # both present
+git -C /home/modelo/matrix-bridge status                                        # .env/config.toml show as ignored, tree clean
+docker compose up -d --build && docker ps --filter name=^/matrix-bridge$
+```
+
+`master` is the release branch (today `master == phase-1`). Track whatever you treat as the
+release line; the commands below assume `origin/master`.
+
+---
+
+## The contract — commands behind each control
+
+Run from `/home/modelo/matrix-bridge` as `modelo`. Each is idempotent and fail-loud
+(non-zero exit ⇒ surface it on the panel; don't swallow).
+
+### Status (poll for the badge)
+
+```sh
+docker inspect -f '{{.State.Status}}|{{.State.StartedAt}}|{{.RestartCount}}' matrix-bridge
+```
+
+- Output e.g. `running|2026-06-15T18:02:11.4Z|0`. Parse field 1 for the badge:
+  - `running` → green/up. Field 3 (`RestartCount`) climbing while status flips to
+    `restarting` ⇒ **crash loop** — show it; that's the most useful signal a dashboard gives here.
+  - `exited` → stopped/crashed.
+  - `restarting` → unhealthy / boot-looping.
+- **Non-zero exit** (`No such object: matrix-bridge`) ⇒ **not deployed** — distinct from
+  "stopped". Show that state rather than erroring out.
+
+Friendlier one-liner for a human-readable badge (empty string when not running):
+
+```sh
+docker ps --filter name=^/matrix-bridge$ --format '{{.Status}}'   # e.g. "Up 2 hours"
+```
+
+### Logs (optional "view logs" action — handy for diagnosing a red badge)
+
+```sh
+docker logs --tail 100 matrix-bridge
+```
+
+### Restart (no code change)
+
+```sh
+docker restart matrix-bridge
+```
+
+### Update (pull latest code + rebuild + recreate) — the headline button
+
+```sh
+cd /home/modelo/matrix-bridge \
+  && git fetch origin \
+  && git reset --hard origin/master \
+  && docker compose up -d --build
+```
+
+- `git reset --hard origin/master` is the deploy-box "always match remote" semantic: never gets
+  stuck on divergence, and gitignored secrets are preserved. (If you'd rather detect divergence,
+  `git pull --ff-only` is the gentler alternative — but then a wedged tree needs manual help.)
+- `docker compose up -d --build` rebuilds the image and recreates the container only if the
+  build changed. First build after a base-image bump is slow (minutes); subsequent builds hit
+  the layer cache. **Treat update as long-running**: stream/await output, set a generous
+  timeout (≥10 min), and don't block the dashboard on it.
+
+### Stop / Start (optional)
+
+```sh
+docker stop matrix-bridge                                    # stop
+cd /home/modelo/matrix-bridge && docker compose up -d        # start (recreates if needed)
+```
+
+---
+
+## Spark Control-side wiring (for the dev)
+
+Map the above onto however Spark Control already registers a managed Spark/service:
+
+1. **Register `matrix-bridge`** as a managed service (a tile), targeting `spark-32d0` over the
+   existing SSH channel, commands run as `modelo`.
+2. **Status badge** ← poll the *Status* command on the panel's normal refresh cadence; map the
+   four states above (running / exited / restarting / not-deployed) to your existing badge
+   vocabulary. Surface `RestartCount` if your tile can show a secondary metric — a climbing
+   count is the crash-loop tell.
+3. **Buttons:** `Update`, `Restart` (required for the exit criterion); `Logs`, `Stop`/`Start`
+   (optional, nice-to-have).
+4. **Fail-loud, surfaced.** Every command's non-zero exit + stderr must reach the panel, not a
+   silent failure — this mirrors matrix-bridge's own discipline (a bad launch reports back into
+   the room rather than hanging). Especially: a failed `git fetch` (Gitea unreachable) or a
+   failed build should show the error, not a stuck spinner.
+5. **`Update` is long-running** — see the timeout/streaming note above.
+
+What I deliberately left generic: the tile's exact place in Spark Control's code, its UI, and
+its config schema — that's yours to fit to the existing pattern. If a precise drop-in matters,
+share how a Spark is currently registered (config entry + the command-runner seam) and I'll
+tailor steps 1–5 to it.
+
+---
+
+## Acceptance (maps to the ROADMAP exit)
+
+- [ ] Status tile shows the bot's live state and flips correctly across a manual
+      `docker stop` / `docker start` on the Spark.
+- [ ] `Restart` from the panel cycles the container (status returns to `running`).
+- [ ] `Update` from the panel pulls a new commit, rebuilds, and recreates the container — and
+      surfaces a clear error if Gitea is unreachable or the build fails.
+
+---
+
+## Note — optional future enhancement (not required for Phase 3)
+
+The *Status* command reports container liveness (process up), not Matrix connectivity — the bot
+can be `running` yet disconnected from Synapse. A truer signal would need a Docker `HEALTHCHECK`
+backed by a bot-side liveness signal (e.g. the bot touches a file or exposes a tiny endpoint on
+each successful sync loop), after which Status could read `{{.State.Health.Status}}`. That's a
+matrix-bridge-side change, out of scope here — flag it if/when "running but silent" actually bites.
