+# 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.

+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-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}`
+(current memory string) 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: test)
+
+`update_memory(memory)` sets the responder's memory to the passed
+value and persists that value. (D12: the argument was ignored.)
+
+### 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-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.

+# 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.

+# SPEC-008 — Configuration
+
+TOML config per deployment (`kroa.toml`, `ggg.toml` — both untracked;
+`config.toml` in the repo is the placeholder sample). Loaded by
+`FjerkroaBot.load_config`, hot-reloaded by a watchdog observer
+(defect D9 — reload race — is tracked in FDB-004 and will refine
+these requirements).
+
+### CFG-01 — TOML config loads into a plain dict (coverage: test)
+
+`FjerkroaBot.load_config(path)` parses the TOML file and returns its
+top-level table as a dict; responders read raw keys from it.
+
+### CFG-02 — Per-channel system prompt override (coverage: test)
+
+A responder bound to channel `X` uses `config["X"]` as its system
+prompt when that key exists, else `config["system"]`. One deployment
+can speak differently per channel.
+
+### CFG-03 — Missing news file leaves the placeholder untouched (coverage: test)
+
+When `news` points to a non-existent file, the `{news}` placeholder
+stays literal in the system prompt (no crash, no empty substitution).
+
+### CFG-04 — Config hot-reload applies on the event loop (coverage: test)
+
+The watchdog observer thread never mutates live config references
+itself: a detected change is loaded, then the swap of `bot.config`
+and all responder `.config` references is scheduled onto the event
+loop (`call_soon_threadsafe`), so no request ever reads a
+half-swapped config (D9). Before the loop runs (startup), the swap
+applies directly — there are no concurrent readers yet.

+# SPEC-009 — Persistence
+
+One SQLite database per deployment (`<history-directory>/bot.db`),
+replacing the per-channel pickle files (`<channel>.dat`,
+`<channel>.memory`). Stdlib `sqlite3` via worker threads — no new
+dependency (D-010). Without `history-directory` in config the bot
+runs memory-only, as before.
+
+### PER-01 — History survives restarts (coverage: test)
+
+History entries written through the store are returned, in order and
+per channel, by a fresh store instance on the same database file.
+
+### PER-02 — Memory survives restarts (coverage: test)
+
+The per-channel memory string written through the store is returned
+by a fresh store instance on the same database file.
+
+### PER-03 — Existing pickles migrate exactly once (coverage: test)
+
+On responder start, when the database holds no rows for the channel
+and legacy pickle files exist, their content is imported and the
+pickle files are renamed to `*.migrated` (kept for rollback). A
+second start does not re-import. Users keep their history through
+the cutover (review consensus: migration is a decision, not an
+accident).
+
+### PER-04 — Database hygiene (coverage: test)
+
+The database runs in WAL journal mode, carries `PRAGMA user_version`
+= schema version (currently 1) for future migrations/rollback
+policy, and the file is chmod 0600 (it stores conversation data).
+
+### PER-05 — Writes run off the event loop (coverage: test)
+
+History and memory persistence happen in a worker thread
+(`asyncio.to_thread`) — a slow disk cannot stall Discord event
+handling (D6).
