   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 (Superseded by D-014: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-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.

+# 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.

+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

+
+### 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).

+# 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.

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

+`deploy/deploy.sh <host> <tag>` refuses unknown hosts and refs that
+are not tags. The tag's tree is extracted over `~/fjerkroa_bot` —

+never touched. Dev-on-host drift ends here: hosts run tag content
+only.

+
+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

+# 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)
+`bot_initiated_allowed()` is false: no boreness, later no scheduler
+posts. Replies to users stay unaffected — a guest asking at 23:30
+still gets an answer.

+"""Persona golden-prompt eval — the FDB-006 model-cutover gate.
+
+Sends the same golden prompts to two models using the deployment's
+real system prompt and the production envelope, and writes a
+side-by-side markdown report. A human judges; this script only
+collects.
+
+Usage:
+  uv run python tools/persona_eval.py --config .temp/kroa.toml \
+      --models gpt-4.1 gpt-5.6-luna --set kroa --out eval-out/kroa.md
