+# 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.
+- **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-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.

+# 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**
+5. Get an access token using this curl command:
+   ```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'
+   ```
+6. Save the `access_token` from the response
+
+### 2. Configure the Bot
+
+Update your `config.toml` file:
+
+```toml
+# IGDB Configuration for game information
+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**
+   - Regenerate access token (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.

+# 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:

+# 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 — System prompt template substitution (coverage: test)
+
+`message()` substitutes `{date}` (YYYY-MM-DD), `{time}`, `{memory}`
+(the assembled memory block — legacy memory string while the
+structured memory is inactive, see MEM-10) in the system prompt;
+`{news}` is replaced with the news file content when the configured
+file exists and stays literal when it does not.
+
+### 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_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-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.

+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

+### 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)

+
+### 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
+restoring this backup.
+
+### DEP-04 — Smoke test gates the deploy (coverage: manual)
+
+After restart the script fails loudly unless the service reports
+RUNNING and the log shows a fresh Discord login line. On failure the
+operator instruction is printed: deploy the previous tag (DEP-06).

+Deploys to fjerkroa between 11:00 and 22:00 Europe/Oslo are refused
+unless `DEPLOY_FORCE=1` is set. The restaurant does not beta-test
+during dinner.
