codex mechanicus search (spec-014): ground warhammer lore in binaric.tech via codex_search tool

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 — ADR log
+
+Decisions inside the set architecture. D-NNN, never renumbered.
+
+- **D-001** — SDD+BDD+TDD adopted (2026-07-13). SPEC-system port:
+  numbered requirements in `specs/`, coverage classes
+  feature/test/manual, `tools/trace.py` enforcement in `make check`.
+  Process is binding — see SPEC-000.
+- **D-002** — BDD runs at the responder seam, not against live
+  services. `FakeModelResponder` scripts model output; Discord-event
+  behavior is unit-tested with mocked discord.py objects. Rationale:
+  Discord ToS forbids test-account automation and LLM output is
+  nondeterministic — a live-BDD lane would be flaky by construction.
+- **D-003** — Packaging = uv + pyproject only (2026-07-13). setup.py,
+  requirements.txt and pytest.ini removed; single source of truth,
+  locked via uv.lock. Python `>=3.11` floor keeps the kitchen host
+  (py3.11) deployable until FDB-016 lands.
+- **D-004** — openai SDK pinned `<2` (1.109.x). The v2 SDK migration
+  happens together with the FDB-005 envelope rewrite (structured
+  outputs / Responses API) — one breaking change, one test cycle,
+  instead of two.
+- **D-005** — `--strict-markers` stays on; requirement tags from
+  `.feature` files are registered as pytest markers dynamically in
+  `tests/conftest.py`.
+- **D-006** — FDB-005 stays on chat.completions + structured outputs;
+  the Responses API migration is deferred to FDB-007, where history
+  handling gets redesigned anyway — one conversation-state reshape
+  instead of two.
+- **D-007** — openai SDK bumped to 2.x together with the envelope
+  rewrite (supersedes the D-004 pin). `multiline` dependency dropped —
+  strict schema output made relaxed-JSON parsing dead code.
+- **D-008** — Operator runtime flags (pause/images/tasks/quiet) are
+  in-memory only; a restart resets to config defaults. Persistence
+  arrives with the FDB-011 task store if staff practice demands it.
+- **D-009** — `translate()` still keys off `fix-model` although the
+  repair path is gone; the whole translate-before-draw step dies in
+  FDB-009 (gpt-image-2 is multilingual). Not worth a config rename
+  for one phase. *(Closed 2026-07-13: FDB-009 deleted translate();
+  the fix-model config key is now fully dead and can be dropped from
+  live configs.)*
+- **D-010** — Persistence uses stdlib `sqlite3` via
+  `asyncio.to_thread`, not aiosqlite: no new dependency, and a
+  connection-per-operation with WAL is plenty at this message volume.
+- **D-011** — `save_history` replaces the channel's rows wholesale
+  per message instead of appending: histories are capped at
+  `history-limit` (~200-350 rows) and trims must be reflected;
+  correctness over micro-optimization.
+- **D-012** — Budget spend is *estimated* from configured per-token/
+  per-image prices, not fetched from the billing API: deterministic,
+  testable, no extra scopes. Dashboard hard limits (FDB-001) stay the
+  outer safety net; this ledger is the inner, immediate one. User
+  image quota counts at grant time (reservation), global image spend
+  at generation time.
+- **D-013** — `!forgetme` v1 purges history rows only; the
+  single-string channel memory cannot be selectively cleaned. Full
+  fact-level erasure ships with FDB-007 structured memory — stated in
+  the user-facing confirmation, not hidden. (Superseded by D-014:
+  erasure now covers facts, observations and episode traces.)
+- **D-016** — The reply/ignore classifier fails open (BEH-03): a
+  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-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
+  (delay bypass) and defaults to false without a classifier.
+- **D-015** — Deploys are push-based from the dev machine
+  (`git archive <tag> | ssh`), not pull-based: no deploy keys or git
+  state on the hosts, the artifact is exactly the tag tree, untracked
+  live config survives in-place extraction. Trade-off: deploys need
+  the dev machine; acceptable for a one-operator project.
+- **D-014** — Structured memory (FDB-007): observations are the only
+  consolidation feed (independent of history trimming); consolidation
+  returns NEW facts only (no wholesale rewrite — the lossiness of the
+  old memoize path is exactly what we're removing); self-authorship
+  is enforced in code (fact subject must be an observation author),
+  not just in the prompt; memory reads run on the loop (small indexed
+  SQLite queries), writes off-loop. Legacy memory strings survive as
+  episodes; the memory table stays as a read-only legacy fallback for
+  deployments without memory-model.

+# Fjerkroa Bot Development Guide
+
+This document outlines the development setup and workflows for the Fjerkroa Bot project.
+
+## Development Tools Setup
+
+### Prerequisites
+
+- Python 3.11 (required - use `python3.11` and `pip3.11` explicitly)
+- Git
+
+### Quick Start
+
+```bash
+# Install development dependencies
+make install-dev
+
+# Or manually:
+pip3.11 install -r requirements.txt
+pip3.11 install -e .
+pre-commit install
+```
+
+## Available Development Commands
+
+Use the Makefile for all development tasks. Run `make help` to see all available commands:
+
+### Installation
+- `make install` - Install production dependencies
+- `make install-dev` - Install development dependencies and pre-commit hooks
+
+### Code Quality
+- `make lint` - Run linter (flake8)
+- `make format` - Format code with black and isort
+- `make format-check` - Check if code is properly formatted
+- `make type-check` - Run type checker (mypy)
+- `make security-check` - Run security scanner (bandit)
+
+### Testing
+- `make test` - Run tests
+- `make test-fast` - Run tests without slow tests
+- `make test-cov` - Run tests with coverage report
+
+### Combined Operations
+- `make all-checks` - Run all code quality checks and tests
+- `make pre-commit` - Run all pre-commit checks (format, then check)
+- `make ci` - Full CI pipeline (install deps and run all checks)
+
+### Utility
+- `make clean` - Clean up temporary files and caches
+- `make run` - Run the bot (requires config.toml)
+- `make run-dev` - Run the bot in development mode with auto-reload
+
+## Tool Configuration
+
+All development tools are configured via `pyproject.toml` and `.flake8`:
+
+### Code Formatting (Black + isort)
+- Line length: 140 characters
+- Target Python version: 3.8+
+- Imports sorted and formatted consistently
+
+### Linting (Flake8)
+- Max line length: 140
+- Max complexity: 10
+- Ignores: E203, E266, E501, W503, E306 (for Black compatibility)
+
+### Type Checking (MyPy)
+- Strict type checking enabled
+- Checks both `fjerkroa_bot` and `tests` directories
+- Ignores missing imports for external libraries
+
+### Security Scanning (Bandit)
+- Scans for security issues
+- Skips known safe patterns (pickle, random) for this application
+
+### Testing (Pytest)
+- Configured for async tests
+- Coverage reporting available
+- Markers for slow tests
+
+## Pre-commit Hooks
+
+Pre-commit hooks are automatically installed with `make install-dev`. They run:
+
+1. Built-in checks (trailing whitespace, file endings, etc.)
+2. Black code formatter
+3. isort import sorter
+4. Flake8 linter
+5. Bandit security scanner
+6. MyPy type checker
+7. Fast tests
+
+To run pre-commit manually:
+```bash
+pre-commit run --all-files
+```
+
+## Development Workflow
+
+1. **Setup**: Run `make install-dev`
+2. **Development**: Make your changes
+3. **Check**: Run `make pre-commit` to format and check code
+4. **Test**: Run `make test` or `make test-cov` for coverage
+5. **Commit**: Git will automatically run pre-commit hooks
+
+## Continuous Integration
+
+The `make ci` command runs the complete CI pipeline:
+- Installs all dependencies
+- Runs linting (flake8)
+- Checks formatting (black, isort)
+- Runs type checking (mypy)
+- Runs security scanning (bandit)
+- Runs all tests

+# IGDB Integration Setup Guide
+
+The bot now supports real-time video game information through IGDB (Internet Game Database) API integration. This allows the AI to provide accurate, up-to-date information about games when users ask gaming-related questions.
+
+## Features
+
+- **Game Search**: Find games by name with fuzzy matching
+- **Game Details**: Get comprehensive information including ratings, platforms, developers, genres, and summaries
+- **AI Integration**: Seamless function calling - the AI automatically decides when to fetch game information
+- **Smart Formatting**: Game data is formatted in a user-friendly way for the AI to present
+
+## Setup Instructions
+
+### 1. Get IGDB API Credentials
+
+1. Go to [Twitch Developer Console](https://dev.twitch.tv/console)
+2. Create a new application:
+   - **Name**: Your bot name (e.g., "Fjerkroa Discord Bot")
+   - **OAuth Redirect URLs**: `http://localhost` (not used but required)
+   - **Category**: Select appropriate category
+3. Note down your **Client ID**
+4. Generate a **Client Secret**
+
+### 2. Configure the Bot
+
+Update your `config.toml` file:
+
+```toml
+# IGDB Configuration for game information
+igdb-client-id = "your_actual_client_id_here"
+igdb-client-secret = "your_actual_client_secret_here"
+enable-game-info = true
+```
+
+With the client secret configured, the bot fetches an app access token from
+Twitch itself and refreshes it automatically before it expires (Twitch app
+tokens live ~60 days) — no manual token handling needed.
+
+Alternatively, a static token still works (legacy setup — it expires after
+~60 days and then game lookups fail with 401 until you replace it):
+
+```bash
+curl -X POST 'https://id.twitch.tv/oauth2/token' \
+-H 'Content-Type: application/x-www-form-urlencoded' \
+-d 'client_id=YOUR_CLIENT_ID&client_secret=YOUR_CLIENT_SECRET&grant_type=client_credentials'
+```
+
+```toml
+igdb-client-id = "your_actual_client_id_here"
+igdb-access-token = "your_actual_access_token_here"
+enable-game-info = true
+```
+
+### 3. Update System Prompt (Optional)
+
+The system prompt has been updated to inform the AI about its gaming capabilities:
+
+```toml
+system = "You are a smart AI assistant with access to real-time video game information through IGDB. When users ask about games, game recommendations, release dates, platforms, or any gaming-related questions, you can search for accurate and up-to-date information."
+```
+
+## Usage Examples
+
+Once configured, users can ask gaming questions naturally:
+
+- "Tell me about Elden Ring"
+- "What are some good RPG games released in 2023?"
+- "Is Cyberpunk 2077 available on PlayStation?"
+- "Who developed The Witcher 3?"
+- "What's the rating of Baldur's Gate 3?"
+
+The AI will automatically:
+1. Detect gaming-related queries
+2. Call IGDB API functions to get real data
+3. Format and present the information naturally
+
+## Technical Details
+
+### Available Functions
+
+The integration provides two OpenAI functions:
+
+1. **search_games**
+   - Parameters: `query` (string), `limit` (optional integer, max 10)
+   - Returns: List of games matching the query
+
+2. **get_game_details**
+   - Parameters: `game_id` (integer from search results)
+   - Returns: Detailed information about a specific game
+
+### Game Information Included
+
+- **Basic Info**: Name, summary, rating (critic and user)
+- **Release Info**: Release date/year
+- **Technical**: Platforms, developers, publishers
+- **Classification**: Genres, themes, game modes
+- **Extended** (detailed view): Storyline, similar games, screenshots
+
+### Error Handling
+
+- Graceful degradation if IGDB is unavailable
+- Fallback to regular AI responses if API fails
+- Proper error logging for debugging
+
+## Troubleshooting
+
+### Common Issues
+
+1. **"IGDB integration disabled"** in logs
+   - Check that `enable-game-info = true`
+   - Verify client ID and access token are set
+
+2. **Authentication errors**
+   - Prefer `igdb-client-secret` — the bot then refreshes tokens itself
+   - With a static `igdb-access-token`: regenerate it (they expire)
+   - Verify client ID matches your Twitch app
+
+3. **No game results**
+   - IGDB may not have the game in their database
+   - Try alternative spellings or official game names
+
+### Rate Limits
+
+- IGDB allows 4 requests per second
+- The integration includes automatic retry logic
+- Large queries are automatically limited to prevent timeouts
+
+## Disabling IGDB
+
+To disable IGDB integration:
+
+```toml
+enable-game-info = false
+```
+
+The bot will continue working normally without game information features.

+Feature: Response envelope handling
+  The responder parses the model's JSON envelope and decides what the
+  bot says, where, and whether staff is alerted. (SPEC-001)
+
+  Background:
+    Given a responder with history limit 10
+
+  @ENV-01
+  Scenario: Model answer reaches the user
+    Given the model answers with answer "Hei! Velkommen." and answer_needed "true"
+    When user "alice" sends "Hei bot" in channel "chat"
+    Then the response answer contains "Hei! Velkommen."
+    And the response is marked as needed
+
+  @ENV-02
+  Scenario: Suppressed answer stays silent
+    Given the model answers with answer "irrelevant musing" and answer_needed "false"
+    When user "alice" sends "talking to bob" in channel "chat"
+    Then the response is not marked as needed
+
+  @ENV-03
+  Scenario: Staff note forces delivery
+    Given the model answers with answer "Et oyeblikk!" and staff note "Guest at table 4 needs a waiter"
+    When user "guest" sends "Can somebody help us?" in channel "chat"
+    Then the response staff note is "Guest at table 4 needs a waiter"
+    And the response is marked as needed
+
+  @ENV-04
+  Scenario: Direct messages are always answered
+    Given the model answers with answer "Svar." and answer_needed "false"
+    When user "alice" sends "hei" directly to the bot
+    Then the response is marked as needed
+
+  @ENV-05
+  Scenario: Short-path rules skip the model
+    Given a short-path rule for channels "spam.*" and users "bob.*"
+    When user "bobby" sends "noise noise" in channel "spam-corner"
+    Then the model was not called
+    And the response is empty
+    And the history contains the message from "bobby"
+
+  @ENV-07
+  Scenario: History is trimmed to the limit
+    Given a responder with history limit 4
+    And 6 prior history entries in channel "chat"
+    And the model answers with answer "ok" and answer_needed "true"
+    When user "alice" sends "hei" in channel "chat"
+    Then the history length is at most 4
+
+  @ENV-08
+  Scenario: Markdown links are unwrapped
+    Given the model answers with answer "Se [menyen](https://fjerkroa.example/meny) her" and answer_needed "true"
+    When user "alice" sends "meny?" in channel "chat"
+    Then the response answer contains "https://fjerkroa.example/meny"
+    And the response answer does not contain "[menyen]"
+
+  @ENV-09
+  Scenario: Missing channel falls back to the message channel
+    Given the model answers with answer "ok" and no channel
+    When user "alice" sends "hei" in channel "kitchen-talk"
+    Then the response channel is "kitchen-talk"

+# SPEC-000 — Development process (binding)
+
+This repo is developed spec-driven + behaviour-driven + test-driven.
+
+## The three loops
+
+1. **Spec-driven**: every behavior exists first as a numbered
+   requirement (`<AREA>-NN`) in `specs/SPEC-NNN-*.md`. No code without
+   a requirement. Requirements are never deleted — a dead requirement
+   is marked `(withdrawn: <successor or reason>)` in its title line
+   and keeps its ID forever.
+2. **Behaviour-driven**: every *user-visible* requirement gets at
+   least one Gherkin scenario tagged `@<ID>` in `features/*.feature`,
+   executed by pytest-bdd.
+3. **Test-driven**: implementation starts at a red test. Unit tests
+   cover the non-visible requirements (arithmetic, invariants,
+   parsing).
+
+Change flow: spec change → feature/test red → implementation green →
+refactor.
+
+## Requirement format
+
+```
+### ENV-01 — Model answer reaches the user (coverage: feature)
+
+Normative statement first. Rationale after.
+```
+
+Coverage classes:
+
+- `feature` — needs an `@<ID>` tag in some `.feature` file.
+- `test` — the ID must appear in a test file (docstring or comment
+  of the covering test).
+- `manual` — needs a row in `manual-verification.md` with date and
+  result before the increment demo.
+
+## Enforcement
+
+`tools/trace.py` (stdlib-only) runs in `make check` (and `make
+trace`). It fails the build when a declared requirement lacks its
+coverage class artifact, when a feature tag references an undeclared
+ID, or when an ID is declared twice. Code fences in spec files are
+ignored by trace (the example above does not declare ENV-01).
+
+## Test substrate
+
+BDD scenarios run against the **responder seam**: a
+`FakeModelResponder` subclass with scripted model output — no live
+Discord, no live OpenAI (see DECISIONS.md D-002). Discord-event
+behavior is covered by unit tests with mocked discord.py objects.
+
+## ADRs
+
+Decisions inside the set architecture go to `DECISIONS.md` as
+`D-NNN — title — one-paragraph rationale`. The stack itself is not
+re-litigated there.
+
+## Spec map
+
+- SPEC-000 process (this file, no IDs)
+- SPEC-001 responder + envelope — ENV-NN
+- SPEC-002 memory — MEM-NN (lands with FDB-007)
+- SPEC-003 safety/privacy/abuse — SAF-NN (lands with FDB-014)
+- SPEC-004 images — IMG-NN (lands with FDB-009/010)
+- SPEC-005 self-tasking — TSK-NN (lands with FDB-011)

+# SPEC-001 — Responder + response envelope
+
+Characterization of the current (v2) responder contract in
+`fjerkroa_bot/ai_responder.py`. The model answers with a JSON
+envelope: `answer`, `answer_needed`, `channel`, `staff`, `picture`,
+`picture_edit`, `hack`. FDB-005 will replace the transport of this
+contract (structured outputs); the *behavioral* requirements below
+survive that change unless marked otherwise.
+
+### ENV-01 — Model answer reaches the user (coverage: feature)
+
+When the model envelope carries a non-empty `answer` and
+`answer_needed` is true, `AIResponder.send()` returns an `AIResponse`
+with that answer text and `answer_needed == True`. This is the core
+loop: user talks, bot answers.
+
+### ENV-02 — Suppressed answer stays silent (coverage: feature)
+
+When the model envelope sets `answer_needed` to false (and the
+message is not direct, mentions nobody, and no staff note is set),
+the returned `AIResponse` has `answer_needed == False`. The bot may
+observe without butting in.
+
+### ENV-03 — Staff note forces delivery (coverage: feature)
+
+When the envelope carries a non-null `staff` text and a non-null
+`answer`, the returned response preserves the staff text and has
+`answer_needed == True`. Staff alerts must never be silently
+dropped.
+
+### ENV-04 — Direct messages are always answered (coverage: feature)
+
+When the incoming `AIMessage` is marked `direct` and the model
+returns a non-null answer, `answer_needed` is forced to `True`
+regardless of the model's own `answer_needed`. A user addressing the
+bot directly gets a reply.
+
+### ENV-05 — Short-path rules skip the model (coverage: feature)
+
+When a configured `short-path` `[channel-regex, user-regex]` pair
+matches the message, `send()` appends the message to history, trims
+history to the limit, persists it, and returns an empty response
+(answer `None`, `answer_needed False`) **without calling the model**.
+Cheap archival of noisy channels.
+
+### ENV-06 — Malformed model output is repaired (coverage: withdrawn — successor ENV-18)
+
+Withdrawn 2026-07-13 with FDB-005: strict structured outputs make the
+repair model obsolete. Malformed output now counts as a failed
+attempt — see ENV-18.
+
+### ENV-07 — History is trimmed to the limit (coverage: feature)
+
+After a completed exchange, `len(history) <= history-limit` holds.
+Trimming happens both before the model call and after appending the
+new question/answer pair.
+
+### ENV-08 — Markdown links are unwrapped (coverage: feature)
+
+In the final answer text, `[label](url)` becomes `url` and
+`@[label](url)` becomes `label`. Discord renders raw URLs; markdown
+link syntax from the model reads as noise.
+
+### ENV-09 — Missing channel falls back to the message channel (coverage: feature)
+
+When the envelope `channel` is null/none/empty, the response channel
+is the channel the message came from.
+
+### ENV-10 — Dynamic context reaches the system prompt (coverage: test)
+
+The system message carries the current date, time, news (when the
+configured file exists) and the memory block (legacy string while
+structured memory is inactive, see MEM-10). Since FDB-008 these live
+in a context suffix, not inline — see ENV-20; legacy `{date}`,
+`{time}`, `{news}`, `{memory}` placeholders in operator templates are
+stripped.
+
+### ENV-21 — Tool calls disable reasoning effort (coverage: test)
+
+When function tools are attached to a chat call, the call carries
+`reasoning_effort` (config `reasoning-effort`, default `"none"`) —
+gpt-5.6 models reject tools + reasoning on chat/completions with a
+400 otherwise (found live on ggg 2026-07-13: IGDB tools made Luma
+mute after the Luna cutover). Tool-less calls stay untouched.
+
+### ENV-20 — Persona prefix is byte-stable (coverage: test)
+
+`message()` renders the system message as: static persona text
+(config template with all dynamic placeholders removed) followed by a
+`## Context` suffix holding date, time, news and memory. Two calls in
+the same channel produce byte-identical persona prefixes — the prompt
+cache can actually hit (the old inline `{date}`/`{time}` substitution
+invalidated it every minute).
+
+### ENV-11 — Per-channel history shrink prefers busy channels (coverage: test)
+
+`shrink_history_by_one()` removes the oldest entry whose channel has
+more than `history-per-channel` (default 3) entries; when no channel
+exceeds the cap, the oldest entry overall is removed.
+
+### ENV-12 — Exhausted retries raise, attempts are spaced (coverage: test)
+
+When the model returns no usable answer three times in a row,
+`send()` raises `RuntimeError`. Consecutive attempts are separated by
+an exponential-backoff sleep — failures never hammer the API
+back-to-back (D1).
+
+### ENV-13 — Reaction-clear events are recorded (coverage: test)
+
+`on_reaction_clear(message, reactions)` — the discord.py signature —
+records the clearing in the channel's memory. (D7: the previous
+handler declared `(reaction, user)` and crashed on dispatch.)
+
+### ENV-14 — update_memory persists its argument (coverage: withdrawn — successor SPEC-002)
+
+Withdrawn 2026-07-13 with FDB-007: the per-answer memory rewrite
+(`update_memory`/`memoize`) is deleted; structured memory (MEM-01+)
+replaces it. The D12 defect died with the code.
+
+### ENV-15 — retry-model is used after a rate limit (coverage: test)
+
+After a rate-limited attempt, the next `chat()` attempt uses the
+configured `retry-model` instead of `model`; a successful attempt
+switches back. (D2: the fallback was assigned to a local and never
+took effect.)
+
+### ENV-16 — Model calls are never served from a disk cache (coverage: test)
+
+`openai_chat`/`openai_image` call the client every time. The pickle
+response cache (`openai_chat.dat`) is a test-era artifact and must
+not exist in the production path (D3/D4).
+
+### ENV-17 — IGDB tool execution runs in a worker thread (coverage: test)
+
+`_execute_igdb_function` executes the synchronous IGDB library off
+the event loop (worker thread), returning identical results. The
+event loop keeps serving Discord events during lookups (D5).
+
+### ENV-18 — Malformed or refused output is a failed attempt (coverage: test)
+
+Model output is requested as schema-validated JSON (strict structured
+outputs). Output that still fails to parse, or a model refusal,
+counts as a failed attempt (backoff + retry per ENV-12) — there is no
+repair model, no `fix()` path, no relaxed-JSON fallback. Replaces
+ENV-06.
+
+### ENV-19 — The envelope schema is pinned (coverage: test)
+
+Every chat call carries `response_format` = strict JSON schema named
+`envelope` with exactly the fields `answer`, `answer_needed`,
+`channel`, `staff`, `picture`, `picture_count` (since FDB-009,
+IMG-02), `picture_edit`, `hack` — all required,
+`additionalProperties: false`, nullable where the protocol allows
+null. Tool-followup calls carry the same format.

+# SPEC-002 — Structured memory
+
+Replaces the single-string per-answer LLM rewrite (lossy, O(convo)
+cost — the old `memoize` path). Layers, simplified per plan v4:
+**user facts** (durable, provenance-tracked), **pinned facts**
+(operator-set, global or per channel), **episodes** (rolling channel
+summaries with decay). Channel-facts deferred until recall proves
+insufficient. Raw feed = **observations** (messages, reactions,
+edits, deletes); an async consolidation pass turns observations into
+facts + episodes. The memory system is active only when both a store
+(`history-directory`) and a `memory-model` are configured — otherwise
+the legacy memory string is used read-only (MEM-10).
+
+### MEM-01 — Events become observation rows (coverage: test)
+
+User messages, bot answers, reactions (add/remove/clear), edits and
+deletes are recorded as observation rows (channel, user, kind,
+content excerpt) — cheap writes, no LLM call per event.
+
+### MEM-02 — Consolidation is batched, never per message (coverage: test)
+
+Consolidation triggers when `memory-consolidate-every` (default 20)
+unconsumed observations have accumulated for a channel; it runs as a
+background task guarded by a lock (no overlapping runs), consumes the
+observations it processed, and leaves them in place when the model
+call fails (retry next trigger).
+
+### MEM-03 — Only self-authored facts persist (coverage: test)
+
+The consolidator stores a fact only when its subject user is among
+the authors of the consumed observations, with provenance
+`source='self'`; facts the model attributes to absent third parties
+are discarded and logged. Operator pins carry `source='operator'`.
+"Bob says Alice likes X" must never become Alice's profile
+(review consensus C2).
+
+### MEM-04 — Recall is participant-scoped (coverage: test)
+
+The memory block assembled into the system prompt contains: pinned
+facts (global + this channel), user facts of **conversation
+participants only** (current author + authors in the recent history
+tail), and the channel's recent episodes. Facts of non-participants
+never enter the prompt — the model cannot leak what it cannot see.
+
+### MEM-05 — Episodes decay (coverage: test)
+
+At most `memory-episodes-per-channel` (default 10) episodes are kept
+per channel; consolidation drops the oldest beyond the cap.
+
+### MEM-06 — User facts have a retention limit (coverage: test)
+
+Facts not updated within `memory-fact-retention-days` (default 180)
+are purged during consolidation. Durable is not indefinite (GDPR
+storage limitation).
+
+### MEM-07 — Staff review and edit memory (coverage: test)
+
+Staff commands: `!bot memory <user>` lists the user's facts with ids;
+`!bot forget-fact <id>` deletes one; `!bot pin <channel|global>
+<fact>` adds an operator pin; `!bot unpin <id>` removes one.
+
+### MEM-08 — Legacy memory strings migrate to episodes (coverage: test)
+
+Schema v3 migration copies existing per-channel memory strings into
+an episode row each; pickle migration does the same. Deployments keep
+their accumulated context through the upgrade.
+
+### MEM-09 — !forgetme erases facts, observations and episode traces (coverage: test)
+
+`!forgetme` now deletes the user's facts, their observation rows, and
+episodes mentioning the user's name — in addition to the SAF-08
+history purge. This completes the erasure that SAF-08 v1 could not.
+
+### MEM-10 — Memory system off degrades gracefully (coverage: test)
+
+Without `memory-model` (or without a store) no observations are
+written, no consolidation runs, and `{memory}` falls back to the
+legacy memory string — no crash, no behavior change for
+unconfigured deployments.

+# SPEC-003 — Safety, privacy + abuse hardening
+
+FDB-005 lands the injection-defense subset (the old `hack`
+self-report was the only defense — S4). Consequential actions are
+gated *outside* the model: the model proposes, deterministic code
+disposes. Quotas, budget caps, memory policies and GDPR controls
+follow with FDB-014 (SAF-10+, reserved).
+
+### SAF-01 — Model-proposed channel routing is allowlisted (coverage: test)
+
+A model-proposed answer channel is honored only when it is in the
+allowed set: config `allowed-channels` when set, otherwise the
+channels already named in config (`chat-channel`, `staff-channel`,
+`welcome-channel`, `additional-responders`). Anything else falls back
+to the origin channel and is logged. Prompt injection must not be
+able to redirect the bot into arbitrary channels.
+
+### SAF-02 — Outbound messages cannot ping (coverage: test)
+
+The bot is constructed with `allowed_mentions = none`: no user, role
+or @everyone/@here pings in any outbound message, regardless of what
+the model emits.
+
+### SAF-03 — External text is sanitized before prompting (coverage: test)
+
+Text from external sources injected into prompts or tool results —
+news-feed content and IGDB results — passes `sanitize_external_text`:
+control characters stripped, `@everyone`/`@here` neutralized with a
+zero-width space, length capped (default 4000 chars). RSS headlines
+and game descriptions are attacker-influenced input.
+
+The `hack` envelope field remains as an advisory signal (logged,
+staff-notified) but is no longer the defense.
+
+### SAF-10 — Model calls carry a hashed user identifier (coverage: test)
+
+Chat calls pass `safety_identifier` = a short SHA-256 digest of the
+message author's name — OpenAI-side abuse tracing without shipping
+raw Discord identities (Codex review recommendation).
+
+### SAF-04 — Hard daily budget, fail-closed (coverage: test)
+
+When `daily-budget-usd` is configured and today's estimated spend
+reaches it, no further model or image calls happen: the responder
+refuses before calling the API, and the bot answers nothing until
+midnight. Staff get exactly one alert per day about the silence.
+Cost estimation uses `price-input-per-m` (default 1.0),
+`price-output-per-m` (default 6.0) and `price-per-image` (default
+0.05). A budget of 0 means fully silent — fail-closed by
+construction.
+
+### SAF-05 — Usage is metered and survives restarts (coverage: test)
+
+Token counts (prompt/completion) from every model call and every
+generated image are recorded per calendar day; with a store
+configured the counters persist across restarts (usage table,
+schema v2).
+
+### SAF-06 — Per-user daily message quota (coverage: test)
+
+When `user-daily-messages` is configured, messages beyond the cap
+from one user on one day are ignored (logged, no model call). The
+`system` user (bot-initiated flows) is exempt.
+
+### SAF-07 — Per-user daily image quota (coverage: test)
+
+When `user-daily-images` is configured, picture requests beyond the
+user's daily cap are stripped from the response (the text answer
+still goes out).
+
+### SAF-08 — !forgetme purges a user's history (coverage: test)
+
+`!forgetme` removes the requesting user's messages from all live
+responder histories and from the store, then confirms in-channel.
+Since FDB-007 the purge extends to memory itself — facts,
+observations and episode traces (MEM-09).
+
+### SAF-09 — !privacy states the data practice (coverage: test)
+
+`!privacy` answers with the configured `privacy-notice` (a default
+notice ships in code): what is stored, that `!forgetme` exists.
+Works even while the bot is paused.

+# SPEC-004 — Image generation
+
+Generation on `image-model` (default `gpt-image-2`), base64 end to
+end — no URL downloads, no expiring CDN links in the generation path.
+Optional knobs: `image-size` (default 1024x1024), `image-quality`
+(passed through only when set). The Leonardo path stays behind
+`leonardo-token` until parity is confirmed, then dies. The input
+pipeline (attachment cache, vision, edit/remix) is FDB-010 / IMG-10+.
+
+### IMG-01 — Images arrive as base64 buffers (coverage: test)
+
+`draw_openai(description, count)` requests `count` images and returns
+a list of decoded image buffers straight from the API response; every
+generated image is metered in the ledger (SAF-05).
+
+### IMG-02 — The envelope carries picture_count (coverage: test)
+
+The envelope gains `picture_count` (integer). `post_process` clamps
+it to 1..4 and defaults to 1 when absent (legacy history entries,
+old-model output). ENV-19's field list is revised accordingly.
+
+### IMG-03 — Multiple images, one message (coverage: test)
+
+`picture_count` images are attached as multiple files to a single
+Discord send (the last part when the answer is split, per BEH-06).
+
+### IMG-04 — Legacy image models degrade safely (coverage: test)
+
+When `image-model` is not a `gpt-image-*` model (e.g. `dall-e-3`),
+the count is clamped to 1 and `response_format="b64_json"` is
+requested explicitly (gpt-image models return base64 natively and
+reject the parameter).
+
+### IMG-05 — Picture prompts go to the API untouched (coverage: test)
+
+The translate-before-draw step is deleted: the model's picture prompt
+reaches the image API verbatim (current image models handle
+Norwegian/German natively). The `translate()` method and its
+`fix-model` dependency are gone (closes D-009).
+
+## Input pipeline (FDB-010)
+
+Attachments live in a content-hash cache
+(`<history-directory>/images/<sha256>.<ext>`, index in the store,
+schema v4). Active only with a store; without one the legacy CDN-URL
+path remains.
+
+### IMG-10 — Attachments are ingested at message time (coverage: test)
+
+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)
+
+Bot-generated images are ingested like uploads (user `assistant`), so
+"make a variant of that" remix chains work on the bot's own output.
+
+### IMG-17 — Image-only messages are cached (coverage: test)
+
+A message consisting only of attachments (no text) is ingested into
+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
+how many and that `picture_edit=true` edits the newest — the model
+cannot use a capability it does not know about.

+# 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-006 — Staff / operator controls
+
+Staff operate the bot from the staff channel without SSH. Runtime
+flags live in memory — a restart resets to config defaults (D-008).
+The staff-alert path is a tested contract: alerts are the
+business-critical feature on the restaurant deployment.
+
+### OPS-01 — Staff commands only work in the staff channel (coverage: test)
+
+`!bot …` commands are honored only when sent in the configured staff
+channel. In any other channel the text is treated as a normal
+message.
+
+### OPS-02 — Pause and resume (coverage: test)
+
+`!bot pause` stops all public replying (messages are ignored, no
+model calls); `!bot resume` restores it and clears quiet mode. Staff
+commands keep working while paused.
+
+### OPS-03 — Image kill-switch (coverage: test)
+
+`!bot images off` drops the picture part of any response before
+generation (answer text still goes out); `!bot images on` restores.
+
+### OPS-04 — Quiet mode with auto-resume (coverage: test)
+
+`!bot quiet <minutes>` silences public replies for N minutes, then
+the bot resumes by itself. Friday-service panic button that cannot be
+forgotten.
+
+### OPS-05 — Status report (coverage: test)
+
+`!bot status` answers in the staff channel with the current flags
+(replies / images / tasks / remaining quiet time).
+
+### OPS-06 — Keyword-forced staff alerts (coverage: test)
+
+When a user message matches any configured `staff-alert-keywords`
+regex and the model set no staff note, a staff alert is forced with
+user + message excerpt. Alerting must not depend solely on the
+model's judgement.
+
+### OPS-07 — Staff alerts are rate-limited (coverage: test)
+
+At most `staff-alert-max-per-hour` (default 10) alerts reach the
+staff channel per rolling hour; excess alerts are logged. An
+injection or a glitch must not be able to flood staff.
+
+### OPS-08 — Lost staff alerts are logged (coverage: test)
+
+When a staff alert cannot be delivered (staff channel unresolved),
+the alert text is written to the error log — never silently dropped.
+
+### OPS-09 — Self-tasking kill-switch (coverage: test)
+
+`!bot tasks off` disables bot-initiated posting (today: the boreness
+loop; later: the FDB-011 scheduler); `!bot tasks on` restores.
+Bot-initiated posts also respect pause/quiet.
+
+### OPS-11 — Pins are listable (coverage: test)
+
+`!bot pins` answers with all pinned facts and their ids (global +
+per-channel) — without it, `!bot unpin <id>` required guessing ids.
+
+### OPS-12 — Task queue surface (coverage: test)
+
+`!bot tasks` lists open tasks (queued + awaiting approval) with ids;
+`!bot task-approve <id>` and `!bot task-cancel <id>` manage them
+(TSK-05). `!bot tasks on|off` stays the kill-switch (OPS-09).
+
+### OPS-10 — Spend report (coverage: test)

+
+### DEP-01 — Deploys go by tag, in place, configs survive (coverage: manual)

+Before the restart, every `bot.db` under `~/fjerkroa_bot` is copied
+to `bot.db.pre-<tag>` on the host. Schema migrations are
+forward-only (PER-06) — rolling back past a schema bump means

+
+### DEP-04 — Smoke test gates the deploy (coverage: manual)

+# SPEC-010 — Human-behavior layer
+
+The bot should feel like a considerate participant, not an instant
+wall of text: it decides *whether* to speak with a cheap classifier
+instead of trusting the main model's self-report, paces its replies,
+splits long answers, and sometimes just reacts. All knobs are
+per-deployment TOML; every feature degrades to the previous behavior
+when its knob is unset (config-off = v3.0.0 semantics).
+
+### BEH-01 — Classifier gates non-direct replies (coverage: test)
+
+With `classifier-model` configured, every non-direct user message
+first passes a cheap classification call (reply yes/no, factual
+yes/no, optional reaction emoji). `reply=false` means no main-model
+call happens at all — this is the boreness suppressor and the
+butting-into-conversations fix (replaces trusting `answer_needed`
+alone; the envelope flag still applies afterwards as second gate).
+
+### BEH-02 — Direct messages bypass the gate (coverage: test)
+
+Mentions and DMs never go through the classifier — someone addressing
+the bot always reaches the main model. Welcome and bot-initiated
+flows do not pass the gate either.
+
+### BEH-03 — Classifier failure fails open (coverage: test)
+
+A failed or unparseable classification (API error, budget refusal)
+falls through to the main model. Availability beats savings; the
+budget gate still protects spend.
+
+### BEH-04 — Reply pacing is typing-proportional (coverage: test)
+
+With `typing-chars-per-second` set (recommended 30), the typing
+indicator is held for `len(part) / cps` seconds per message part,
+capped at `typing-max-seconds` (default 8), before sending. Unset or
+0 = no pacing (v3.0.0 behavior).
+
+### BEH-05 — Factual answers skip the artificial delay (coverage: test)
+
+Messages the classifier tagged `factual` (opening hours, prices,
+addresses) are answered without the BEH-04 delay — utility beats
+theater exactly where users are waiting for information.
+
+### BEH-06 — Long answers are split (coverage: test)
+
+Answers longer than `split-threshold` chars (default 1200) are split
+at paragraph (then sentence) boundaries into at most
+`split-max-parts` (default 3) sequential messages, each under the
+Discord 2000-char limit (which unsplit answers would crash into
+today). Attached images go with the last part.
+
+### BEH-07 — Sometimes a reaction is the reply (coverage: test)
+
+When the classifier returns `reply=false` plus a reaction emoji, the
+bot adds that emoji to the user's message instead of staying fully
+silent. Zero main-model cost, human touch.
+
+### BEH-08 — Quiet hours stop bot-initiated posts (coverage: test)
+
+Within `quiet-hours = "HH:MM-HH:MM"` (host-local, may wrap midnight)

+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.

+# SPEC-012 — Operations hardening
+
+Runtime + host operability (FDB-012). Backups and host wiring are
+`manual` coverage; the in-process alerting is `test`.
+
+### OPS-13 — Consistent DB backups (coverage: test)
+
+`deploy/backup_db.py` writes a gzipped snapshot of `bot.db` using the
+sqlite3 online-backup API — consistent even while the bot writes
+(WAL-safe) — with 0600 permissions. Restoring a snapshot yields a
+readable database with the same rows.
+
+### OPS-14 — Backups are rotated (coverage: test)
+
+The newest `backup-keep` (default 14) snapshots are kept; older ones
+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)
+
+The responder counts consecutive OpenAI request failures; at
+`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.

+# 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.

+
+Stdlib only. Collects declared requirement IDs from specs/SPEC-*.md
+headers (code fences stripped), @ID tags from features/*.feature, ID
+mentions from tests/**/*.py, and rows from manual-verification.md.
+Fails when a declared requirement lacks its coverage artifact, when a
+feature tag or manual row references an undeclared ID, or when an ID
+is declared twice.
