   broken classifier must never mute the bot; the budget gate already
   bounds spend. Its verdict gates BEFORE the main call, the
   envelope's answer_needed still gates after — two independent nets.
+- **D-020** — Web search via Exa (FDB-022, SPEC-015): a `web_search`
+  tool alongside fetch_url/IGDB/codex/get_news, filling the "look it up
+  on the open web" gap. Exa (not a raw search-engine scrape) because it
+  returns clean title+url+text in one call — no SSRF surface of our own
+  (we call one fixed API endpoint, not arbitrary hosts), and it pairs
+  with fetch_url for the full article. Key is a host secret
+  (`exa-api-key`, env `EXA_API_KEY` fallback), never repo-side; results
+  sanitized like every other external-text tool; off by default
+  (`enable-web-search`), metered per user.
+- **D-019** — News memory + on-demand tool (SPEC-013 NEWS-07..12):
+  the news pipeline now carries item summaries (feed descriptions,
+  HTML-stripped) and persists every fetched item into a deduped `news`
+  table (schema v6), pruned to a rolling window (`news-keep`). Both the
+  kroa digest run and the ggg posting run write to it, so the store is
+  a single searchable source across both models. A `get_news` tool
+  reads that store (topic/source-filtered, metered, sanitized) rather
+  than re-fetching feeds live: the ambient `{news}` digest stays a
+  small always-on snapshot, while the tool gives unbounded on-demand
+  reach without a fresh network round-trip per call. The store is the
+  same `bot.db` (WAL) the bot uses; the cron process opens it
+  independently — concurrent reader/writer is what WAL is for.
 - **D-018** — Codex Mechanicus search (FDB-019, SPEC-014): Luma's
   lore is grounded in the priest's real archive at binaric.tech via a
   `codex_search` tool over the site's public `search-index.json`, not

+# Operator runbook — Fjærkroa / Luma bot
+
+One page for "something is wrong, what do I do". Two deployments of one
+codebase, both on **uberspace** (push-based deploy from the dev machine —
+there is no git checkout on the hosts).
+
+| | Fjærkroa (café) | Luma (GGG clan) |
+| --- | --- | --- |
+| SSH host | `ssh fjerkroa` (pictor.uberspace.de) | `ssh ggg` |
+| Service | `kroa` | `luma` |
+| Config | `~/fjerkroa_bot/kroa.toml` | `~/fjerkroa_bot/ggg.toml` |
+| Staff channel | `#kassa` | `#mods` |
+| Language / persona | Norwegian, café host | German, "Luma" |
+
+Common paths on each host: bot code `~/fjerkroa_bot`, venv `~/venv-bot`,
+database `~/fjerkroa_bot/history/bot.db` (SQLite, WAL), our snapshots
+`~/backups/<kroa|luma>/`, logs under `~/logs` and `~/tmp`.
+
+## From Discord (staff channel only, prefix `!bot`)
+
+No SSH needed for day-to-day control. Type `!bot help` in the staff
+channel for the full, grouped list. The essentials:
+
+- `!bot pause` / `!bot resume` — stop / start all replies.
+- `!bot quiet <minutes>` — go silent for a while, then auto-resume.
+- `!bot status` — replies/images/tasks flags + quiet time left.
+- `!bot spend` — today's estimated USD spend, tokens, images, budget.
+- `!bot images on|off`, `!bot tasks on|off` — kill-switches.
+
+`!help` works in **any** channel (for everyone) and lists only what is
+usable there. `!forgetme` and `!privacy` also work everywhere, even
+while the bot is paused.
+
+## Restart / check health (SSH)
+
+```sh
+ssh <host>
+supervisorctl status <kroa|luma>          # RUNNING + uptime
+supervisorctl restart <kroa|luma>
+tail -n 40 ~/tmp/<kroa|luma>-stderr*.log   # discord login / errors
+tail -n 40 ~/logs/supervisord.log          # "We have logged in as ..."
+```
+
+A healthy start shows a fresh `connected to Gateway` + `We have logged
+in as ...` line within ~15 s.
+
+## Deploy a release / roll back
+
+From the **dev machine** (`~/Repos/FjerkroaBot`), tags only:
+
+```sh
+git tag -m "<msg>" vX.Y.Z && git push --tags        # cut the release first
+bash deploy/deploy.sh ggg vX.Y.Z                    # luma
+DEPLOY_FORCE=1 bash deploy/deploy.sh fjerkroa vX.Y.Z # kroa (see window)
+```
+
+- kroa refuses to deploy **11:00–22:00 Europe/Oslo** (restaurant hours);
+  `DEPLOY_FORCE=1` overrides. Café is closed Mondays.
+- The script backs up `bot.db` → `bot.db.pre-<tag>` before restart, then
+  smoke-tests (RUNNING + fresh login) and fails loudly if either misses.
+- **Rollback** = deploy the previous tag. If the schema version moved
+  between the two tags, restore the matching `bot.db.pre-<newtag>` first
+  (see below) so the older code meets a schema it understands.
+
+## Restore the database
+
+Three independent daily backup layers exist — pick the freshest good one.
+
+```sh
+ssh <host>
+supervisorctl stop <kroa|luma>
+DB=~/fjerkroa_bot/history/bot.db
+
+# 1) uberspace nightly backup of the whole home (read-only):
+#    /backup = current + daily.0..7 + weekly.1..7  (15 restore points)
+cp /backup/daily.1/home/<user>/fjerkroa_bot/history/bot.db "$DB"
+
+# 2) our own rotated gzip snapshot (03:17 UTC cron, keep 14):
+gunzip -c ~/backups/<kroa|luma>/bot-YYYYMMDD-HHMMSS.db.gz > "$DB"
+
+# 3) the pre-deploy snapshot for a given release:
+cp "$DB".pre-vX.Y.Z "$DB"
+
+rm -f "$DB"-wal "$DB"-shm    # drop stale WAL sidecars after a restore
+supervisorctl start <kroa|luma>
+```
+
+`<user>` is `fjerkroa` or `ggg`. The DB holds conversation history,
+structured memory, usage ledger, image cache index, tasks, and the news
+store — all regenerable, none critical. That is why there is no off-host
+backup: uberspace `/backup` + the on-host snapshots are enough.
+
+## Rotate a secret
+
+Secrets live only in the host `*.toml` (never in the repo). Edit in
+place and restart:
+
+```sh
+ssh <host>
+# OpenAI: edit  openai-token = "sk-..."   in kroa.toml / ggg.toml
+# Discord: edit discord-token = "..."     (get a new token from the
+#          Discord developer portal → Bot → Reset Token first)
+supervisorctl restart <kroa|luma>
+```
+
+After rotating an OpenAI key, revoke the old one in the OpenAI dashboard.
+Keep a `*.toml` backup before editing; a broken TOML crash-loops the
+service (validate: `~/venv-bot/bin/python -c 'import tomlkit; tomlkit.load(open("kroa.toml"))'`).
+
+## Scheduled jobs (crontab -l)
+
+| Host | When (server time) | Job |
+| --- | --- | --- |
+| both | `17 3 * * *` | `backup_db.py` → `~/backups/<bot>/` (keep 14) |
+| kroa | `5 * * * *` | news digest → `{news}` file + news store |
+| ggg | `*/15 * * * *` | news poster → #news/#newsjp webhooks + store |
+
+Logs: `~/backups/<bot>/backup.log`, `~/backups/<bot>/news*.log`.
+
+## Quick triage
+
+- **Bot silent everywhere** → `!bot status` (paused/quiet?), else
+  `supervisorctl status`; if not RUNNING, `restart` and read stderr.
+- **Bot silent in one channel** → check the host config `ignore-channels`
+  / `short-path` rules for that channel (a stray `short-path` rule can
+  archive messages without replying).
+- **Repeated API errors** → the bot posts a rate-limited alert to the
+  staff channel after 5 consecutive OpenAI failures (OPS-16); check
+  `!bot spend` (budget hit?) and the OpenAI status/key.
+- **Bad deploy** → roll back to the previous tag (above).

+
+`parse_feed` also captures each item's short description — RSS

+# SPEC-015 — Web search (Exa)
+
+A `web_search` function tool for general "look it up on the internet"
+questions the other tools do not cover: IGDB is games, the Codex is
+Adeptus Mechanicus lore, the news store is the configured feeds, and
+`fetch_url` needs a URL the user already has. Web search fills the gap
+and pairs with `fetch_url` (search → pick a link → read it). Results are
+external text and are sanitized (SAF-03); the Exa key is a host secret,
+never in the repo. Active only when `enable-web-search = true` and a key
+is present.
+
+### WEB-01 — web_search is offered as a tool (coverage: test)
+
+When `enable-web-search` is true **and** an Exa key is available
+(`exa-api-key` in config, else `EXA_API_KEY` env), the chat call's
+`tools` list includes a `web_search` function (`query` string, optional
+`num_results`). With the flag off or no key it is absent.
+
+### WEB-02 — Results are reduced and sanitized (coverage: test)
+
+Each Exa result becomes `{title, url, snippet, published}`; `title` and
+`snippet` pass through `sanitize_external_text` (snippet capped at
+`web-snippet-chars`, default 400) so a web page can neither inject an
+`@everyone` nor smuggle control characters into the prompt.
+
+### WEB-03 — Result count is bounded (coverage: test)
+
+`num_results` is clamped to 1..`MAX_RESULTS` (10) before the request, so
+neither a huge fan-out nor a zero/negative count reaches the API.
+
+### WEB-04 — Missing key and API failure are reported, not raised (coverage: test)
+
+With no key the tool returns an `{error: ...}` result without a network
+call. A request that raises (network, non-2xx, bad JSON) is logged and
+returns an `{error: ...}` dict — `search` never raises into the loop.
+
+### WEB-05 — Searches are metered per user (coverage: test)
+
+Each `web_search` increments a per-user daily counter; over
+`web-daily-per-user` (default 30) the tool refuses with an error result
+without calling the API. The budget gate (SAF-04) still applies to the
+surrounding model calls.
