Memory was a scrapbook: notes accumulated, nothing kept them consistent, and shared memory had no rule saying what belonged in it. This adopts the LLM-wiki pattern — the assistant maintains an evolving artifact rather than re-deriving knowledge each session. The schema (agents/common/memory-wiki.md, included by the three type:chat agents) adds an append-only log.md beside each index.md, names Ingest / Recall / Lint as habits, and states the rule for shared memory: write it there only if you would say it out loud with every member in the room. One person's health, results or another member's opinion of them stays private — that is what shared folders, not shared memory, are for. Tampering is the reason the rules are shaped this way. Shared facts carry provenance and are superseded rather than erased, and a member who contradicts a fact they did not write gets a logged CLAIM instead of an overwrite: only the originator or an admin can turn it into a change. The approval gate cannot enforce this — it asks the caller, who is the same person pushing — so a per-role write permission on shared memory is still the real boundary. The prompt is the etiquette, not the fence. append_file is a new fs tool because the log needs a write that cannot shorten a file. On memory paths it is one SQL statement, so concurrent appends (parallel tool batches, two sessions of one user) cannot lose a line — a dropped line in an audit trail is worse than a failed write. It is auto-allowed on shared-memory/log.md at a lower priority than the shared write rule: gating the trail would be friction with no safety, and a rejected log write yields an unlogged change. memory::scaffold seeds index.md / log.md / user.md so the schema does not describe files that do not exist. Seeded empty rather than left absent: a missing note resolves to nothing at injection, so the model cannot tell "nothing recorded yet" from "this mechanism is not running". __MEMBERS__ renders the roster from users + roles instead of a note the model maintains. A remembered copy drifts and can be talked into being edited; this one bypasses the model entirely. users.notes are excluded — they are the admin's private notes about a person and this block is visible to every member. Still open: a UI to browse memory (list_dir does not classify memory paths yet), a tool-written revisions table (log lines are still typed by the model), and the periodic lint pass.
Agent icons — style guide
Each agent in the agents/ directory can have an icon/avatar declared in the "icon" field of its meta.json. The backend serves the file via GET /api/agents/{id}/icon.
Visual style
Icons are generated with Vector Paintings LoRA via ComfyUI in a warm, family-friendly style:
- Style: painterly vector — bold shapes fused with expressive brushstrokes
- Technique: vivid colours, emotion, motion, warm lighting
- Format: square (1024×1024), rendered as a character portrait
- Background: warm, cozy, medium-bright (no dark/no neon)
- Subject: a warm animal character representing the agent's role, with contextual elements (tools, symbols, objects)
- Palette: terracotta, amber, warm gold, coral, soft teal — warm and inviting
- Trigger word:
VectorPaintDaalmust be included at the start of the prompt

Adding a new agent icon
- Generate the image using the Vector Paintings prompt template above (include
VectorPaintDaalat the start) - Save it as
agents/{agent_id}/icon.png - Add
"icon": "icon.png"to the agent'smeta.json(if not already present) - No code changes needed — the backend serves whatever file path is declared in the manifest
