kb: batch from 2026-07-30 parallel run (#181 #183 #189 #192 #164 #128 #219)

Work produced by the /kb driver on 2026-07-30. Each change is recorded on its Kanboard task; all remain Done-unverified or parked pending alvis's decisions. #183 agap-mcp/src/gitea.js askpassScript() and giteaWikiWrite()'s wiki checkout both used /tmp/agap-mcp-wiki, so writing the askpass helper made the dir non-empty and git clone always failed. gitea_wiki_write had likely never succeeded in production. Askpass moved to its own dir. #181 agap-mcp/src/server.js Initialise registeredToolCount at module load so /health reports the real count immediately instead of 0 until the first MCP request. #189 kanboard/backup.sh, seafile/backup.sh, vaultwarden/backup.sh, users-backup.sh, openai/backup-{hindsight-adolf,llm-dbs}.sh Remove the dead *.ts Zabbix trapper pushes (never landed). users-backup.sh also pointed at localhost:81 instead of 192.168.1.4:81 and pushed a date string into a numeric item. Freshness monitoring now rides the .age items. #192 RESTORE-RUNBOOK.md, {kanboard,seafile,vaultwarden}/restore.sh Restore path for the three services, verified in throwaway containers. Note: this work found Seafile backups have carried an empty ccnet_db.sql since 2026-07-07 -- filed as kb#222, not fixed here. #164 openai/litellm-config.yaml Metered `judge` (anthropic/claude-haiku-4-5) entry removed per alvis's 2026-07-30 decision. ANTHROPIC_API_KEY was never wired, so it could not spend. #128 openai/agent_registry.py litellm_key_spec() now also grants the routing-mode aliases, gated by the same _reachable_tiers() check as raw grants, so a small-tier agent cannot acquire automatic routing that resolves to tier-large. #219 openai/migrate-adolf-state.sh Migration script only; inert until run. Copies (never moves) the openai_adolf-state volume to /mnt/ssd/dbs/adolf, verifying a full sha256 manifest before declaring success. Tested against a throwaway volume. Deliberately NOT included, both awaiting alvis: agap-mcp/docker-compose.yml -- kb#174's contested BW_EMAIL revert (parked). openai/docker-compose.yml -- kb#219's bind-mount switch; the target dirs under /mnt/ssd/dbs/adolf do not exist yet, so committing it would let a later `compose up` recreate Adolf against empty paths.

+# Restore Runbook — Kanboard, Vaultwarden, Seafile
+
+Companion to each service's `backup.sh`. Covers kb#192.
+
+Each service now has a `restore.sh` next to its `backup.sh`:
+- `kanboard/restore.sh`
+- `vaultwarden/restore.sh`
+- `seafile/restore.sh`
+
+All three follow the same convention: they default to the **live** container
+names/paths, but every target is overridable via env vars, so the exact same
+script restores into a real disaster or into a disposable/throwaway
+container for a dry-run test. **Never invoke a restore.sh without env
+overrides unless you are doing a real, intentional disaster recovery** —
+the defaults point at production.
+
+## Before you restore anything
+
+1. `/mnt/backups/<service>/` is read-only in practice — copy the snapshot
+   you want out to a scratch dir first, don't operate on it in place.
+2. Confirm you have the right snapshot: `ls /mnt/backups/<service>/` and
+   pick the newest dir, but **check its contents aren't empty** (see the
+   Seafile gotcha below — an empty dump looks like a valid directory).
+3. Restoring into the live container is destructive and briefly stops the
+   service. Only do this for a real incident, and say so out loud before
+   running it.
+
+## Kanboard
+
+```bash
+cp -r /mnt/backups/kanboard/<snapshot>  /tmp/kb-restore
+# Real disaster recovery (overwrites the live "kanboard" container):
+cd /home/alvis/agap_git/kanboard
+./restore.sh /tmp/kb-restore
+```
+
+What it does: stops the `kanboard` container, replaces `db.sqlite` via
+`docker cp`, restores `plugins.tar.gz` if present, restarts, then verifies
+by querying `SELECT COUNT(*) FROM tasks` through the container's PHP PDO
+sqlite driver (kanboard's image has no sqlite3 CLI).
+
+Throwaway test (no live impact — no ports published, isolated volumes):
+```bash
+docker volume create kb_restore_test_data
+docker volume create kb_restore_test_plugins
+docker run -d --name kanboard-restore-test \
+  -v kb_restore_test_data:/var/www/app/data \
+  -v kb_restore_test_plugins:/var/www/app/plugins \
+  -e PLUGIN_INSTALLER=true kanboard/kanboard:latest
+
+CONTAINER=kanboard-restore-test ./restore.sh /tmp/kb-restore
+
+# Teardown
+docker rm -f kanboard-restore-test
+docker volume rm kb_restore_test_data kb_restore_test_plugins
+```
+
+**Verified 2026-07-30**: restored the 2026-07-28 03:00 snapshot into a
+throwaway container this way. `tasks` table came back with 180 rows;
+container started healthy. Throwaway container and volumes torn down after.
+
+## Vaultwarden
+
+```bash
+cp -r /mnt/backups/vaultwarden/<snapshot>  /tmp/vw-restore
+# Real disaster recovery (overwrites /mnt/ssd/dbs/vw-data and the live
+# "vaultwarden" container — needs root; the data dir is root-owned):
+cd /home/alvis/agap_git/vaultwarden
+sudo ./restore.sh /tmp/vw-restore
+```
+
+What it does: stops the `vaultwarden` container, copies the `db_*.sqlite3`
+snapshot to `db.sqlite3`, restores `config.json`, `rsa_key*`,
+`attachments/`, `sends/`, restarts, then checks the DB file is in place
+(the vaultwarden image has no `sqlite3` CLI either — verification falls
+back to a file-presence/size check and reading the startup log for a
+clean launch with no re-keying).
+
+Throwaway test (isolated data dir, isolated container, no ports published):
+```bash
+mkdir -p /tmp/vw-data-test
+docker run -d --name vaultwarden-restore-test --user 1000:1000 \
+  -v /tmp/vw-data-test:/data vaultwarden/server:latest
+
+CONTAINER=vaultwarden-restore-test DATA_DIR=/tmp/vw-data-test \
+  ./restore.sh /tmp/vw-restore
+
+# Teardown
+docker rm -f vaultwarden-restore-test
+rm -rf /tmp/vw-data-test
+```
+Note: `--user 1000:1000` is only needed for the throwaway test so the bind
+mount is writable by a non-root operator; the live container runs as root
+and the live data dir is root-owned, so a real restore needs `sudo`.
+
+**Verified 2026-07-30**: restored the 2026-07-28 02:00 snapshot into a
+throwaway container this way. `db.sqlite3` landed at the correct size,
+`config.json` was picked up ("Using saved config from `data/config.json`"
+in the startup log), and the RSA key was reused rather than regenerated
+(no "Private key created" line on the post-restore boot) — i.e. structural
+restore confirmed. Row-level vault content was not inspected (per
+Vaultwarden-handling rules — never surface real vault contents). Throwaway
+container and scratch dir removed after.
+
+## Seafile
+
+```bash
+cp -r /mnt/backups/seafile/<snapshot>  /tmp/sf-restore
+# Real disaster recovery (drops+reloads ccnet_db/seafile_db/seahub_db in
+# the live "seafile-mysql" container, and rsyncs the data dir back into
+# /mnt/misc/seafile, stopping/starting the "seafile" container around it —
+# needs root; data dir is root-owned):
+cd /home/alvis/agap_git/seafile
+sudo ./restore.sh /tmp/sf-restore
+```
+
+What it does: refuses to run if any of the three `*.sql` dumps in the
+snapshot is missing/empty (see gotcha below), then for each of
+`ccnet_db`/`seafile_db`/`seahub_db`: `DROP DATABASE IF EXISTS` +
+`CREATE DATABASE` + reload from the dump, and reports table counts as a
+sanity check. If the snapshot has a `data/` dir and `SEAFILE_CONTAINER` is
+set (default), it also stops the seafile app container, rsyncs `data/`
+into `DATA_DIR`, and restarts it.
+
+**Env-var gotcha fixed during this task**: `SEAFILE_CONTAINER=""` used to
+fall back to the live container name, because `${VAR:-default}` treats an
+empty string as unset. It's now `${VAR-default}` so an explicit empty
+string really means "skip the data-dir step." If you want a DB-only
+restore, pass `SEAFILE_CONTAINER=""` explicitly.
+
+Throwaway test (DB-only, fully isolated MariaDB container + scratch data dir):
+```bash
+docker volume create sf_restore_test_db
+docker run -d --name seafile-mysql-restore-test \
+  -e MYSQL_ROOT_PASSWORD=<test-only-pw> \
+  -e MYSQL_USER=seafile -e MYSQL_PASSWORD=<matches SEAFILE_MYSQL_DB_PASSWORD> \
+  -e MYSQL_DATABASE=placeholder \
+  -v sf_restore_test_db:/var/lib/mysql mariadb:10.11
+# grant seafile broad perms on this throwaway instance only:
+docker exec seafile-mysql-restore-test mysql -u root -p<test-only-pw> \
+  -e "GRANT ALL PRIVILEGES ON *.* TO 'seafile'@'%'; FLUSH PRIVILEGES;"
+
+mkdir -p /tmp/sf-data-test
+MYSQL_CONTAINER=seafile-mysql-restore-test \
+  SEAFILE_CONTAINER=seafile-app-does-not-exist-test \
+  DATA_DIR=/tmp/sf-data-test \
+  ./restore.sh /tmp/sf-restore
+
+# Teardown
+docker rm -f seafile-mysql-restore-test
+docker volume rm sf_restore_test_db
+rm -rf /tmp/sf-data-test
+```
+
+**Verified 2026-07-30 — partially**: DB restore was verified end-to-end
+into a throwaway MariaDB container using the last known-good snapshot
+(2026-07-04 02:00 — see the critical finding below): `ccnet_db` (13
+tables), `seafile_db` (46 tables), `seahub_db` (127 tables) all restored
+and importable. The `data/` directory step ran cleanly against an isolated
+scratch dir (`/tmp/sf-data-test`, not `/mnt/misc/seafile`) — the on-disk
+tree (`seafile-data/`, `seadoc-data/`, `onlyoffice-data/`) landed as
+expected. **A full running Seafile app-stack test (seafile+redis+caddy
+actually serving content from the restored data) was not attempted** — that
+would need the full compose stack, matching `JWT_PRIVATE_KEY`/hostname
+config from `.env`, and meaningfully more setup than the box's read-only
+`/mnt/backups` + non-root constraints support cleanly in one pass. If a
+full app-level restore drill is wanted, treat it as separate follow-up
+work with root access.
+
+### ⚠️ Critical finding: Seafile backups have been broken since 2026-07-07
+
+Every `/mnt/backups/seafile/<snapshot>` from **2026-07-07 through the
+latest, 2026-07-28**, contains only an **empty** `ccnet_db.sql` (0 bytes)
+and nothing else — no `seafile_db.sql`, `seahub_db.sql`, or `data/`. The
+last known-good snapshot is **2026-07-04 02:00**. `restore.sh` now refuses
+to run against a snapshot with a missing/empty dump file rather than
+silently "restoring" an empty database, but **the backup cron job itself
+is still broken** and needs its own fix (likely the `mysqldump` credentials
+in `seafile/backup.sh` no longer matching the live `seafile` MySQL user, or
+similar — not diagnosed further here since reproducing it requires running
+`mysqldump` against the live `seafile-mysql` container, which is out of
+scope for a restore-focused task and was blocked by the sandbox's
+action classifier during this session). **Recommend filing a new,
+separate task to fix `seafile/backup.sh`** — this is a live gap: three
+weeks of Seafile backups are currently useless.

+# Migration script for kb#219 — move Adolf's runtime state off the named
+# Docker volume (openai_adolf-state) onto a host bind mount at
+# /mnt/ssd/dbs/adolf/state, matching the convention every other Agap
+# service already follows (hindsight, litellm, qdrant, langfuse, ...).
+#
+# SAFETY MODEL:
+#   - COPY ONLY. Never touches or deletes the source volume. The volume
+#     stays intact and usable as a rollback source until a human explicitly
+#     removes it (see rollback section in the compose-diff writeup /
+#     kb#219 report), long after this script has run and the container has
+#     been soak-tested on the new mount.
+#   - Dry-run by default. Pass --apply to actually copy.
+#   - Idempotent. Safe to re-run; re-copying onto an already-populated
+#     destination just refreshes it (cp -a overwrite-in-place). It will
+#     NOT delete files at the destination that were removed from the
+#     source between runs -- if that matters, wipe the dest dir yourself
+#     before re-running.
+#   - Verifies file counts + a sha256 manifest diff between source and
+#     destination before declaring success. Non-zero exit if they disagree.
+#   - Uses only `docker run` (alvis is in the `docker` group -- no `sudo`
+#     needed for container operations) to read the volume; never reads
+#     /var/lib/docker/volumes directly (root-only, 0700).
+#   - Does NOT create /mnt/ssd/dbs/adolf itself. That directory tree is
+#     root-owned (/mnt/ssd/dbs is 0755 root:root, same as every other
+#     service dir under it) and must be created + chowned by a human with
+#     sudo first -- see the paste-ready root block in the kb#219 report.
+#     This script aborts early with a clear message if the destination
+#     parent doesn't exist or isn't writable.
