operator help: complete + context-aware (ops-17): !bot help full grouped list, !help for everyone per-channel

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).

   envelope's answer_needed still gates after — two independent nets.
+- **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

+# SPEC-013 — News digest
+
+Replaces the broken pre-1.0-openai `news_feed.py`. A CLI
+(`python -m fjerkroa_bot.news --config <cfg>`) fetches 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 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.

+# SPEC-014 — Codex Mechanicus search
+
+Luma is an Adeptus Mechanicus tech-priest; her lore has a real home —
+the priest's own Codex Mechanicus at `binaric.tech` (an Astro/MDX
+archive, five tongues). A `codex_search` function tool lets her consult
+that archive and answer from sourced inscriptions instead of inventing
+lore. The index is public but still untrusted by the time it reaches a
+prompt: the fetch is SSRF-guarded (SPEC-011 shares `guard_url`),
+size-bounded, and every returned field is sanitized (SAF-03). Luma-only;
+active only when `enable-codex = true`.
+
+### CDX-01 — codex_search is offered as a tool (coverage: test)
+
+When `enable-codex` is true, the chat call's `tools` list includes a
+`codex_search` function (`query` string, optional `lang`) next to any
+IGDB / fetch_url tools. When false, it is absent.
+
+### CDX-02 — The index is fetched safely and cached (coverage: test)
+
+The index URL (`codex-index-url`, default
+`https://binaric.tech/search-index.json`) passes the SSRF guard before
+any network call, is read under a byte cap (`codex-max-bytes`, default
+4 MB) with a download timeout, and is cached in memory for
+`codex-cache-ttl` (default 3600 s) so repeated searches do not re-fetch.
+
+### CDX-03 — Ranking weights title over summary over body (coverage: test)
+
+The query is tokenized (stopwords dropped); each inscription is scored
+by term hits weighted title (8) > summary (3) > body (1). Results are
+returned highest-score first, each as `{title, summary, collection,
+url}`, with `url` absolute against the site origin.
+
+### CDX-04 — Language is preferred, with fallback (coverage: test)
+
+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.
