   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

+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-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.
