beh-11: addressed-only channels — silent unless mentioned, replied to, or named; scheduled tasks skip them

search_games used `where name ~ "<q>"*`: prefix-only, diacritic- and
word-order-sensitive -- "MARVEL Tōkon" found nothing though IGDB has
it. Switch to IGDB's native `search` clause (relevance-ranked,
diacritic-insensitive).

fetch_url and image downloads read bodies with content.read(n), which
returns only the first buffered chunk (~7 KB): pages collapsed to
their <title>. httpread.read_capped collects chunks up to the byte
cap; image downloads read limit+1 so over-limit files are still
rejected instead of cached truncated (IMG-10).

DECISIONS.md

@@ -60,6 +60,57 @@ Decisions inside the set architecture. D-NNN, never renumbered.
   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-021** — Health monitoring (FDB-012, SPEC-012 OPS-18/19): a
+  separate `monitor_loop` (own cadence, default 300 s) rather than
+  folding checks into the 60 s task loop — monitoring is coarse and
+  should not run every minute. Checks are edge-triggered (alert on the
+  rising edge, re-arm on recovery) so a standing condition never spams;
+  they reuse the existing rate-limited staff-alert path. Metrics are
+  the cheap, high-signal ones (spend vs budget, free disk, task-queue
+  depth); each is independently skippable when it has no data, so a
+  deployment without a budget or store still runs the others. Opt-in
+  (`enable-monitoring`) like every other operational rollout.
+- **D-021** — Responses API behind `use-responses-api` (FDB-028,
+  ENV-22..24, resolves D-006): the responder path can use
+  `/v1/responses`, which allows tools + `reasoning_effort` (the
+  chat/completions 400 from ENV-21) and keeps one chain of thought
+  across tool rounds. Stateless by choice: `store=false` +
+  encrypted reasoning items passed back — GDPR posture unchanged, no
+  server-side conversation retention. Flag defaults off; rollback is
+  a config toggle (hot-reload), not a deploy. Classifier /
+  consolidation / task-gen stay on chat/completions (no tools, no
+  reasoning need — not worth the churn).
+- **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
+  a bot-side copy — the index stays a single source of truth, refreshed
+  by the site's own publish rite, and the bot caches it in memory
+  (TTL). It reuses SPEC-011's `guard_url` + `read_capped` (fetch is
+  SSRF-guarded and byte-bounded) and sanitizes every returned field:
+  one's own web content is still untrusted by the time it reaches a
+  prompt. Luma-only (`enable-codex`, off elsewhere) — the Adeptus
+  Mechanicus archive has no place in Fjærkroa's café persona.
 - **D-017** — All human-behavior knobs default to off/v3.0.0
   semantics; behavior changes are config rollouts per deployment, not
   code flips. The classifier's `factual` flag is the only coupling

+# 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).

+(as `text.format`), tools in the flat Responses shape, and

+Classifier, consolidation and task-proposal calls stay on
+chat/completions.

+### ENV-23 — Responses tool loop is stateless and keeps reasoning (coverage: test)
+
+The Responses path runs with `store=false` and
+`include=["reasoning.encrypted_content"]` (nothing retained
+server-side). On a function call, the reasoning and function_call
+output items are passed back as input — reduced to their input-shape

+unknown parameters (live 400, 2026-07-17) — together with one

+Attachments live in a content-hash cache

+

+
+Every image attachment is downloaded immediately (timeout, size cap
+`image-max-bytes` default 8 MB) and stored under its content hash.
+Only sniffed png/jpeg/gif/webp bytes are accepted — extension and
+declared MIME are ignored (attacker-controlled). Rejected content is
+dropped and logged (D11 root fix + cache-abuse hardening).
+
+### IMG-11 — Vision reads from the cache, never CDN URLs (coverage: test)
+
+Vision parts are `data:` URLs built from cached bytes. Discord's
+signed, expiring CDN URLs never reach the model or the history.
+
+### IMG-12 — The cache is capped and aged (coverage: test)
+
+`image-cache-mb` (default 500) LRU-evicts oldest-first;
+`image-cache-ttl-days` (default 90) ages entries out. Eviction always
+removes file and index row together.
+
+### IMG-13 — picture_edit edits the newest channel images (coverage: test)
+
+`picture_edit=true` calls `images.edit` with up to the 4 newest
+cached images of the answer channel as inputs (API max is 16; 4 keeps
+prompts sane). An empty cache falls back to plain generation — the
+flag alone must never fail a reply.
+
+### IMG-14 — Deletion propagates to the cache (coverage: test)
+
+Deleting a Discord message purges its cached images; `!forgetme`
+purges all of the user's images — files and rows (extends
+SAF-08/MEM-09).

+### IMG-15 — Generated images join the cache (coverage: test)
+

+### IMG-17 — Image-only messages are cached (coverage: test)
+

+the cache and recorded as an observation, even though no reply is
+produced — the image must be available for later `picture_edit` and
+vision follow-ups. (Previously the empty-text early-return dropped
+such posts entirely.)
+
+### IMG-16 — The prompt announces editable images (coverage: test)
+
+When the answer channel has cached images, the context suffix states

+# SPEC-005 — Self-tasking
+
+The sigmoid "boreness" loop becomes a persistent task queue (schema
+v5): generators propose, a scheduler executes — through the normal
+responder path, so every SAF gate, quota and kill-switch applies.
+**Default off** (`tasks-enabled`, kitchen stays quiet unless opted
+in); generators are individually selectable per persona
+(`tasks-generators`). Marked experimental per plan v4.
+
+### TSK-01 — Tasks are persistent queue rows (coverage: test)
+
+A task is a store row: kind, channel, due-at, payload (the prompt the
+responder will run), state (`queued`/`approval`/`done`/`cancelled`/
+`failed`). Enqueued tasks survive restarts.
+
+### TSK-02 — Due tasks run through the responder path (coverage: test)
+
+The scheduler executes due queued tasks as system messages via the
+normal respond flow (inheriting budget, gates, envelope), marks them
+`done`/`failed`, and records the outcome as an observation so memory
+learns what the bot did on its own.
+
+### TSK-03 — Off by default (coverage: test)
+
+Without `tasks-enabled = true` nothing is generated and nothing is
+executed. A restaurant server does not improvise unless asked to.
+
+### TSK-04 — Per-channel daily cap (coverage: test)
+
+At most `tasks-max-per-channel-per-day` (default 2) task executions
+per channel per day, counted in the ledger; further due tasks stay
+queued for the next day.
+
+### TSK-05 — Approval mode (coverage: test)
+
+With `tasks-approval = true`, generated tasks enter state `approval`
+and a staff alert announces them; `!bot task-approve <id>` moves them
+to the queue, `!bot task-cancel <id>` kills them (works for queued
+tasks too). Staged-rollout path from the review.
+
+### TSK-06 — Kill-switches govern execution (coverage: test)
+
+Task execution respects `bot_initiated_allowed()` — `!bot tasks off`,
+pause, quiet mode and quiet hours all stop the scheduler tick.
+
+### TSK-07 — Idle-impulse generator (boreness, demoted) (coverage: test)
+
+When the chat channel has been idle longer than
+`idle-impulse-hours` (default 12), the generator enqueues one
+impulse task with the configured boreness prompt — deterministic
+threshold instead of the old 7-second sigmoid dice loop, bounded by
+TSK-04. The `on_boreness` loop is gone.
+
+### TSK-08 — Follow-up generator proposes from memory (coverage: test)
+
+Periodically (`taskgen-interval-hours`, default 6) the follow-up
+generator asks `memory-model` (strict structured outputs) whether the
+recent episodes/facts warrant one follow-up task (channel, prompt,
+due-in-hours). A null/failed proposal enqueues nothing.

+# SPEC-011 — URL reading
+
+A `fetch_url` tool alongside IGDB: the model decides when to read a
+link (user pastes a URL + question; a news item links an article
+Luma wants details on). Web pages are the number-one injection
+vector, so everything fetched is sanitized (SAF-03) and the fetch
+itself is SSRF-guarded — the bot runs on shared hosting. Active only
+when `enable-url-reading = true`.
+
+### URL-01 — fetch_url is offered as a tool (coverage: test)
+
+When `enable-url-reading` is true, the chat call's `tools` list
+includes a `fetch_url` function (url string param) next to any IGDB
+tools. When false, it is absent.
+
+### URL-02 — Only http/https are fetched (coverage: test)
+
+`file:`, `ftp:`, `data:`, `gopher:` and schemeless inputs are
+refused before any network call, with an error result the model can
+relay.
+
+### URL-03 — SSRF guard blocks non-public addresses (coverage: test)
+
+Before fetching, the host is resolved and every resulting IP is
+checked; the fetch is refused when any is private, loopback,
+link-local, or otherwise non-global (RFC1918, 127/8, 169.254/16,
+::1, fc00::/7, etc.). A URL literal that is already such an IP is
+refused without DNS.
+
+### URL-04 — Redirects are re-validated (coverage: test)
+
+Redirects are followed manually; each hop's target passes URL-02 and
+URL-03 again. A public URL that 302-redirects to `localhost` or an
+internal IP is refused at the redirect, not fetched. **HTML
+meta-refresh** redirects (link shorteners, the old getnews stubs) are
+also followed — the target is SSRF-re-guarded and fetched, so the
+reader returns the real article, not the "Redirecting…" stub.
+
+### URL-05 — Fetched text is bounded and sanitized (coverage: test)
+
+Responses are capped at `url-max-bytes` (default 2 MB) with a
+download timeout; HTML is reduced to readable text (script/style
+dropped, tags stripped, whitespace collapsed) and passed through
+`sanitize_external_text` before it reaches the model, truncated to
+`url-max-chars` (default 6000).
+
+### URL-06 — Page images feed the cache (coverage: test)
+
+Up to `url-max-images` (default 2) prominent images (og:image, then
+large `<img>`) are ingested into the ImageCache for the requesting
+channel (SSRF-guarded like the page), so the model can see them and
+`picture_edit` can remix them. Ingestion failures are skipped, never
+fatal to the text result.
+
+### URL-07 — Fetches are metered and capped (coverage: test)
+
+Each fetch increments a per-user daily counter; over
+`url-daily-per-user` (default 20) `fetch_url` refuses with an error
+result. The budget gate (SAF-04) still applies to the surrounding
+model calls.
+
+### URL-08 — Main-content extraction (coverage: test)
+
+`fetch_url` text drops page chrome: content inside
+`nav`/`header`/`footer`/`aside`/`form`/`select`/`button` is skipped
+like scripts, and text blocks dominated by link text (over 60 % of a
+block's characters inside `<a>` and the block shorter than 200 chars
+— menus, related-article lists, tag clouds) are treated as
+boilerplate and removed. Body paragraphs with inline links survive.
+The default `url-max-chars` cap rises to 8000 now that the budget is
+spent on content, not chrome.
+
+### URL-09 — Fetched images become vision input (coverage: test)
+
+The images the URL reader already caches from a fetched page
+(`og:image` first, then body images, `url-max-images` cap, every
+candidate SSRF-guarded and magic-byte-sniffed by the image cache) now
+travel to the model as image input alongside the tool result — the
+model sees the picture, not just an `images_cached` count. A URL
+whose response is itself an image (content-type `image/*`) is
+ingested directly and returns text `(image)`; a body at the byte cap
+is treated as possibly truncated and not ingested. The data URLs
+ride in a `vision` key that the responder detaches before the JSON
+tool text is built (a base64 data URL would blow the 8000-char
+sanitizer cap): they are appended as `input_image` items on the
+Responses path and as `image_url` parts on the legacy path. Vision
+is per-turn — nothing extra is historised; the file stays in the
+image cache for later `picture_edit` (IMG-15).

+sqlite3 online-backup API — consistent even while the bot writes
+(WAL-safe) — with 0600 permissions. Restoring a snapshot yields a

+are deleted. Timestamped names sort chronologically so rotation is a
+pure list operation.
+
+### OPS-15 — Backup cron on each host (coverage: manual)
+
+Each host runs `backup_db.py` daily via cron, writing to
+`~/backups/<bot>/` (outside `~/fjerkroa_bot`, so deploys and service
+restarts never touch it). Verified by presence of the cron line and a
+fresh snapshot.
+
+### OPS-16 — Repeated API errors alert staff (coverage: test)

+`api-error-alert-threshold` (default 5) in a row it fires one staff
+alert (rate-limited like all staff alerts) so a silently-broken bot
+(cf. the gpt-5.6 tools/reasoning incident) surfaces within minutes
+instead of hours. A success resets the counter.
+
+### OPS-18 — Health monitor watches spend, disk, task-queue (coverage: test)
+
+When `enable-monitoring` is true, a loop wakes every `monitor-interval`
+(default 300 s) and checks three thresholds, alerting the staff channel
+when one is crossed: daily spend at or above `monitor-spend-alert-frac`
+(default 0.8) of `daily-budget-usd`; free disk below `monitor-disk-min-mb`
+(default 500 MB); open task-queue depth at or above `monitor-taskqueue-max`
+(default 20). A check with no data to evaluate (no budget set, no store,
+a failed disk read) is skipped, never fatal. With the flag off the loop
+does nothing.
+
+### OPS-19 — Alerts fire once per crossing and re-arm on recovery (coverage: test)
+
+Each metric alerts only on the rising edge — the first tick that finds
+it over its threshold — and stays silent while it remains over, so a
+persistent condition does not repeat every interval. When the metric
+falls back below the threshold the alert re-arms silently, ready to fire
+again on the next crossing. All alerts still pass through the

+`news-feeds` and writes a compact digest to the `news` file that
+`AIResponder.message` injects into the `{news}` slot. Feeds are
+external input and operator-configured.
+
+### NEWS-01 — RSS (2.0 and 1.0/RDF) and Atom parse to items (coverage: test)
+
+`parse_feed(bytes, label)` extracts `{title, link, source}` from both
+RSS (`<item>`) and Atom (`<entry>`) documents, tolerates malformed
+XML (returns an empty list, logs), and never raises.
+
+### NEWS-02 — Digest is sanitized and bounded (coverage: test)
+
+`render_digest` caps at `news-max-items`, and every headline passes
+`sanitize_external_text` (SAF-03) — a feed cannot inject `@everyone`
+or control characters into the prompt via a headline.
+
+### NEWS-03 — Feeds are SSRF-guarded and deduped (coverage: test)
+
+`NewsFetcher.collect` skips any feed URL the SSRF guard rejects,
+skips feeds that fail to fetch (one bad feed never sinks the run),
+and drops duplicate headlines across feeds.
+
+## Webhook posting (ggg model)
+
+`--post` mode fetches feeds mapped to channels and posts NEW items to
+the channel's Discord webhook — replacing the py3.8 `getnews.py`
+(dead play3 feed, 35 MB substring-scan state file, HTML-redirect
+cruft). Config: `news-post-feeds = [[url, label, channel], …]`,
+`news-post-webhooks = {channel = url}`, `news-post-state`.
+
+### NEWS-04 — Only unseen items post, then are marked seen (coverage: test)
+
+`NewsPoster.run_post` posts each item whose key (link, else title) is
+not in the seen-set, adds it to the set, and posts to the mapped
+channel's webhook. Re-runs over the same feed post nothing new.
+
+### NEWS-05 — First run seeds without flooding (coverage: test)
+
+With no prior state file (`seed_only`), every current item is marked
+seen but nothing is posted — migrating off getnews.py never dumps a
+backlog into the channels. `news-post-max-per-run` caps steady-state
+posts per run.
+
+### NEWS-06 — Post failures and bad channels are survived (coverage: test)
+
+A feed the SSRF guard rejects, a feed that fails to fetch, an item
+whose channel has no configured webhook, and a webhook POST that
+raises are each logged and skipped — one failure never sinks the
+run, and the seen-set still advances for successfully-processed
+items.
+
+### NEWS-07 — Item summaries are extracted (coverage: test)
+
+`parse_feed` also captures each item's short description — RSS
+`<description>`, Atom `<summary>` or `<content>` — with HTML stripped,
+entities unescaped, and whitespace collapsed, so an item carries what
+it is about, not only a headline. Missing descriptions yield an empty
+summary, never an error.
+
+### NEWS-08 — The digest carries summaries (coverage: test)
+
+`render_digest` appends the sanitized, length-capped
+(`news-summary-chars`, default 200) summary after each headline, so
+the bot's ambient `{news}` context knows the gist of each story, not
+just its title. A zero cap restores the title-only digest.
+
+### NEWS-09 — Fetched news is stored, deduped, and rolled over (coverage: test)
+
+Both the digest run (kroa) and the posting run (ggg) upsert every
+fetched item into a `news` table keyed by link (or title), so the same
+story is stored once. After each run the store is pruned to the newest
+`news-keep` rows (default 400), a rolling window that bounds growth
+while keeping recent history searchable.
+
+### NEWS-10 — get_news is offered as a tool (coverage: test)
+
+When `enable-news-tool` is true and a store is configured, the chat
+call's `tools` list includes a `get_news` function (optional `topic`,
+`source`, `limit`) next to the other tools. Without a store or the
+flag it is absent.
+
+### NEWS-11 — get_news retrieves filtered, sanitized items (coverage: test)
+
+`get_news` returns recent stored items, newest first, optionally
+narrowed by `topic` (every keyword must appear in the title, summary,
+or source label — so `topic: "Nordland"` finds items from that source)
+and/or an exact `source`; `limit` is clamped to 1..30. Each result's title and
+summary are passed through `sanitize_external_text`. The bot can then
+`fetch_url` a returned link for the full article.
+
+### NEWS-12 — get_news is metered per user (coverage: test)
+
+Each `get_news` call increments a per-user daily counter; over
+`news-daily-per-user` (default 30) the tool refuses with an error
+result without touching the store. The budget gate (SAF-04) still
+applies to the surrounding model calls.
+
+### NEWS-13 — Topic misses degrade softly, never empty-handed (coverage: test)
+
+A `topic` whose AND-match (NEWS-11) finds nothing falls back to an
+any-term match, ranked by how many keywords hit (ties: newest first);
+if that too is empty, the newest stored items are returned instead.
+Both fallbacks set a `note` field naming the degradation so the model
+can answer honestly ("nothing on that exactly, but…"). A model
+passing a multi-word or wrong-language topic (the live
+`"Nordland road accident"` → `[]` case) thus still gets usable
+context. Exact matches return no `note`.

+Results are filtered to the requested `lang` (en, de, eo, no, uk;
+default en; unknown codes fall back to en) by the language segment in
+each inscription URL. If no inscription in that tongue matches, the
+search falls back to all tongues rather than returning nothing.
+
+### CDX-05 — Results are sanitized and failure is reported (coverage: test)
+
+Each `title` and `summary` is passed through `sanitize_external_text`
+and length-capped (`codex-summary-chars`, default 500). An index that
+cannot be fetched or parsed returns an `{error: ...}` dict the model can
+relay — `search` never raises.
+
+### CDX-06 — Searches are metered per user (coverage: test)
+
+Each `codex_search` increments a per-user daily counter; over
+`codex-daily-per-user` (default 50) the tool refuses with an error
+result without touching the index. The budget gate (SAF-04) still
+applies to the surrounding model calls.
+
+### CDX-07 — Luma cites the codex, not invention (coverage: manual)
+
+With the persona grounding line, when a pilgrim asks Cult Mechanicus
+lore Luma consults `codex_search` and answers from it, offering the
+`binaric.tech` link to read the full inscription rather than
+hallucinating. Verified live on ggg.

+# 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.

+# SPEC-016 — Weather tool (get_weather)
+
+Both personas talk about weather (the sea over the skerries, rain on
+patch day) but had to guess it. `get_weather` grounds that in the
+free MET Norway Locationforecast API (api.met.no, User-Agent
+required, no key). Locations are host-configured coordinates — the
+model picks by name, it never supplies raw URLs, so there is no SSRF
+surface (one fixed API host).
+
+### WEA-01 — Tool offered only when configured (coverage: test)
+
+The chat call's tools include `get_weather` only when
+`enable-weather` is true AND `weather-locations` (a list of
+`[name, lat, lon]` entries) is non-empty. Otherwise it is absent.
+
+### WEA-02 — Compact sanitized forecast (coverage: test)
+
+The tool reduces the MET compact timeseries to: the named location,
+current conditions (temperature °C, wind m/s, symbol), and a small
+set of forecast points (next hours / tomorrow) with temperature,
+symbol and precipitation. Location names pass
+`sanitize_external_text`; numbers are numbers. Nothing else from the
+API response reaches the prompt.
+
+### WEA-03 — Location matched by name, defaults to first (coverage: test)
+
+The `location` argument matches configured entries
+case-insensitively by substring; no or unknown location = the first
+configured entry. Coordinates never come from the model.
+
+### WEA-04 — Errors return, never raise; calls are metered (coverage: test)
+
+API/network failures return an `{error}` dict (the responder keeps
+running). Each call counts against a per-user daily cap
+(`weather-daily-per-user`, default 30) like the other tools.
