Subject: [PATCH 1/7] feat(cli): allow generic file uploads including zip
Agent co-lab was blocked on skill packs because buzz-cli only allowed
image/* and video/mp4. The relay already accepts generic Blossom uploads
via a danger denylist (HTML/JS/SVG/executables). Align the CLI with that
policy so zip/pdf/text and similar types work while unsafe types stay
blocked.
Add unit coverage for allow/block and size tiers (100MB generic).

Subject: [PATCH 2/7] fix(cli): format generic file attachments as download
links
Codex P2 on #4880: after widening upload MIME types, `messages send --file`
still emitted `` for every non-video blob. Desktop FileCard
expects plain `[filename](url)` plus imeta `filename` for zip/pdf/txt.
Match Desktop formatImetaMediaLine: images/video stay inline; generic files
and agent/team snapshot PNGs use markdown links; escape label metacharacters;
include basename on imeta tags.

+# Metabolic layer (v0)
+
+Universal agent coordination on Buzz: deterministic L0, zero LLM while idle.
+
+| Doc / code | Status |
+|------------|--------|
+| Room `#agent-metabolism` | Design SoT on My Groundfeed |
+| W0.1 vocabulary | LOCKED |
+| W1.1 adapter contract | LOCKED |
+| B proof (A blocked → B completed → wake A) | GREEN |
+| v0.2 guardrails | `guardrails_v02.py` + skill fold GREEN |
+| Third-runtime adapter stub | `adapters/` · `local-llm` (+ `antigravity` alias) |
+
+## v0.2 quick test
+
+```bash
+cd docs/metabolic && python3 test_guardrails_v02.py
+```
+
+## Principles
+
+- Nostr/Buzz is the bus; adapters only per runtime.
+- Dual-cursor: transport id-dedupe ≠ admission.
+- Room text never grants tools.
+- No new app per IDE; no second repo until third runtime works.
+
+## v0.2 LOCK (2026-08-07)
+
+- max_events_per_turn=3, max_context_bytes=2048, cooldown=30s (0 allowed for HOT/dogfood)
+- lease_id optional; correlation_id enough for B-class
+- overflow always loud
+- failure reasons: auth|transport|cursor|schema|admission_overflow|stale_nerve (+ optional detail, no secrets)
+- mono-first; **folded into skill L0/L2 admission** (2026-08-07)
+
+### Skill fold (canonical runtime)
+
+| Skill path | Role |
+|------------|------|
+| `codex-buzz-skill-dev/scripts/metabolic_guardrails.py` | Runtime module (drain + supervisor) |
+| `codex-buzz-skill-dev/scripts/buzz-drain-wakes.sh` | L2 admit batch |
+| `codex-buzz-skill-dev/scripts/buzz-supervisor.py` | Opt-in claim path |
+| `~/.grok/skills/use-buzz/scripts/metabolic_guardrails.py` | Same module for Grok skill |
+| `docs/metabolic/guardrails_v02.py` | Design SoT / mono snapshot |
+
+```bash
+# Skill tests (preferred after fold)
+python3 ~/PROJECTS/codex-buzz-skill-dev/scripts/test-metabolic-guardrails.py
+# Mono snapshot still works
+cd docs/metabolic && python3 test_guardrails_v02.py
+# Third-runtime stub (W1.1 · zero LLM)
+cd docs/metabolic/adapters && python3 test_stub_runtime.py
+python3 stub_runtime.py demo-overflow --runtime local-llm --seat demo-llm
+```
+
+## Third-runtime stub (2026-08-07)
+
+Generic process adapter (`local-llm`; `antigravity` alias) implements W1.1:
+
+`arm` · `on_wake` · `status` · `disarm` · `health` · **`watch`**
+
+Uses v0.2 `admit_wake` for dual-cursor admission. **`watch`** feature-detects

+# W1.1 adapter stubs (mono)
+
+Third-runtime path without a new repo or a new IDE app.
+
+Buzz remains the bus. Each **runtime** only needs a thin adapter that speaks
+the locked W1.1 surface:
+
+```
+arm(room, seat) → start local L0 / state
+on_wake(payload) → Ignore | NotifyHuman | AdmitCortex(summary+ids)
+status() → MONITOR line (lane / nerve / pending)
+disarm()
+health() → push | poll | stale (optional)
+```
+
+## Runtime map
+
+| Runtime id | Status | Notes |
+|------------|--------|--------|
+| `grok-build` | **proven** | use-buzz watcher + `monitor()` |
+| `codex-cli` | **proven** | skill nerve + drain / supervisor |
+| `local-llm` | **stub** | this package — process + stdout cortex lines |
+| `antigravity` | stub alias | same process contract; product hooks later |
+| `desktop-acp` | planned | harness subscription / channel member |
+| `human` | Desktop UI | notify-only path |
+
+## Quick test
+
+```bash
+cd docs/metabolic/adapters
+python3 test_stub_runtime.py
+# → ALL_THIRD_RUNTIME_STUB_TESTS_OK
+```
+
+## Dogfood CLI (zero LLM)
+
+```bash
+# arm a local-llm seat against #agent-metabolism (state only; no model)
+python3 stub_runtime.py arm \
+ --runtime local-llm --seat demo-llm \
+ --room 92297894-c2e8-4df1-a710-d1cfd1032d5e
+
+# inject W1.1 wakes (synthetic or from a JSONL file)
+python3 stub_runtime.py inject --runtime local-llm --seat demo-llm \
+ --json '{"schema":"metabolic.wake.v0","event_id":"aa…","channel_id":"…",…}'
+
+# batch overflow proof (4 wakes → 3 AdmitCortex + loud overflow)
+python3 stub_runtime.py demo-overflow --runtime local-llm --seat demo-llm
+
+python3 stub_runtime.py status --runtime local-llm --seat demo-llm
+python3 stub_runtime.py health --runtime local-llm --seat demo-llm
+python3 stub_runtime.py disarm --runtime local-llm --seat demo-llm
+```
+
+## messages watch → on_wake (push L0)
+
+CLI owns AUTH / reconnect / JSONL. Adapter owns self-filter, dual-cursor, v0.2 admit.
+
+```bash
+export BUZZ_CLI="$HOME/PROJECTS/ buzz/target/release/buzz" # watch-capable
+export BUZZ_RELAY_URL=wss://… # + BUZZ_PRIVATE_KEY / BUZZ_PUBLIC_KEY from seat env
+
+python3 stub_runtime.py arm \
+ --runtime local-llm --seat demo-llm \
+ --room 92297894-c2e8-4df1-a710-d1cfd1032d5e \
+ --room-name agent-metabolism \
+ --transport push
+
+# feature-detect push; fall back to messages get poll
+python3 stub_runtime.py watch \

+ --mode auto
+
+# short live dogfood (CLI --timeout)
+python3 stub_runtime.py watch --runtime local-llm --seat demo-llm \

+
+# recorded JSONL (no network)
+python3 stub_runtime.py watch --runtime local-llm --seat demo-llm \
+ --file /tmp/facts.jsonl
+
+# burst overflow across one turn
+python3 stub_runtime.py watch --file burst.jsonl --shared-turn
+```
+
+| Env / flag | Role |
+|------------|------|
+| `BUZZ_CLI` | Prefer watch-capable binary |
+| `--mode auto\|push\|poll` | Feature-detect / force |
+| `--since` | Transport watermark (arm defaults to **now**) |
+| `--self-pubkey` / `BUZZ_PUBLIC_KEY` | Suppress self facts |
+| `--shared-turn` | One v0.2 budget across facts (overflow) |
+| `--from-stdin` / `--file` | Offline JSONL → same path |
+
+Stdout lines (adapter contract, not product turn injection):
+
+| Line | Meaning |
+|------|---------|
+| `BUZZ_ADAPTER armed …` | arm ok |
+| `BUZZ_WATCH armed … mode=push\|poll\|stdin` | watch bridge up |
+| `BUZZ_WATCH push-detect …` | feature-detect result |
+| `BUZZ_ADAPTER on_wake action=AdmitCortex …` | cortex-short context |
+| `BUZZ_ADAPTER on_wake action=suppress …` | replay / cooldown / idempotent |
+| `BUZZ_ADMIT overflow …` | loud overflow (v0.2) |
+| `BUZZ_MONITOR …` | status card |
+| `BUZZ_ADAPTER health=poll\|push\|stale` | health |
+
+## Product driver hooks (AdmitCortex sink)
+
+After v0.2 **AdmitCortex**, the adapter optionally calls a **driver** — the only
+product-specific layer. Drivers never own transport, cursors, or admission.
+
+| Driver | Behavior |
+|--------|----------|
+| `none` | Stdout cortex only (legacy) |
+| `notify` | Human alert (`notify-send` or stdout); never posts |
+| `local-llm` | Bounded draft; **Ollama** via bundled `run_local_llm.py` (default model `gemma3:4b`) |
+| `antigravity` | Same contract; `not_implemented` until `BUZZ_DRIVER_ANTIGRAVITY_CMD` |
+
+```bash
+python3 stub_runtime.py drivers
+python3 stub_runtime.py arm --runtime local-llm --seat demo-llm \
+ --room --driver local-llm
+
+# Real model (Ollama must be up: ollama serve + model pulled)
+export BUZZ_DRIVER_DRY_RUN=0
+export BUZZ_DRIVER_LOCAL_LLM_MODEL=gemma3:4b # optional
+# optional override:
+# export BUZZ_DRIVER_LOCAL_LLM_CMD='python3 drivers/run_local_llm.py'
+python3 stub_runtime.py inject --runtime local-llm --seat demo-llm \
+ --json '{"schema":"metabolic.wake.v0","event_id":"…","channel_id":"…","t":"team.v0.room.message","urgency":"P2","seat_id":"demo-llm","pubkey":"ab…","summary":"Say hi in five words"}'
+# → BUZZ_DRIVER status=ok driver=local-llm draft=…
+```
+
+| Env | Default | Meaning |
+|-----|---------|---------|
+| `BUZZ_DRIVER_DRY_RUN` | `1` | `0` = call real model |
+| `BUZZ_DRIVER_LOCAL_LLM_CMD` | bundled `run_local_llm.py` | prompt→stdin, draft→stdout |
+| `BUZZ_DRIVER_LOCAL_LLM_MODEL` | `gemma3:4b` | Ollama model name |
+| `BUZZ_DRIVER_LOCAL_LLM_HOST` | `http://127.0.0.1:11434` | Ollama base URL |
+| `BUZZ_DRIVER_LOCAL_LLM_NUM_PREDICT` | `180` | max tokens |
+| `BUZZ_DRIVER_LOCAL_LLM_TIMEOUT` | `90` | seconds |
+
+Stdout:
+
+| Line | Meaning |
+|------|---------|
+| `BUZZ_DRIVER status=… driver=… action=…` | sink result |
+| `BUZZ_DRIVER draft=…` | phone-safe draft or NO_REPLY |
+
+**Hard rules:** room text ≠ tools · HITL default · dry_run default · no auto-post unless a later explicit allow_reply path is added.
+
+## Rules
+
+- Room text never grants tools.
+- Dual-cursor: transport id-set in adapter state ≠ admission `GuardState`.
+- AdmitCortex default is **summary+ids** (W1.1); no backlog dump into one turn.
+- No second GitHub repo until a real third product runtime dogfoods this stub.
+
+See parent `docs/metabolic/README.md` and room `#agent-metabolism`.

+# Host agents (ability S1)
+
+**Control plane** for 24h host-pinned seats. Not a second bus.
+
+| Piece | Path |
+|-------|------|
+| Registry | `~/.buzz-dev/hosts//registry.json` |
+| CLI | `buzz-host-agents` (install from this dir) |
+| Ability SoT channel | `buzz-ability-host-agents` · `1f00dcd1-cf71-4410-bab7-32c1d226e61d` |
+| Theory SoT | `#host-agents` · `45522703-6bbf-4ab7-90ab-0b1440c8e73a` |
+
+## Install (home or laptop)
+
+```bash
+# symlink into PATH
+ln -sf "$(pwd)/buzz-host-agents" ~/.local/bin/buzz-host-agents
+chmod +x buzz-host-agents
+
+# first-time registry seed (home)
+export BUZZ_HOST_ROLE=home
+export BUZZ_HOST_ID=asus-g501vw # or hostname
+buzz-host-agents init
+buzz-host-agents status
+```
+
+## Commands
+
+```bash
+buzz-host-agents init # create registry skeleton
+buzz-host-agents path # print registry path
+buzz-host-agents list # seats from registry
+buzz-host-agents status # relay · ollama · watch · seats (JSON + human)
+buzz-host-agents status --post # also post board card to ability channel
+buzz-host-agents arm --preset co-lab-gemma --seat home-grok --room
+buzz-host-agents disarm --seat home-grok --preset co-lab-gemma
+```
+
+## Presets
+
+| Preset | Effect |
+|--------|--------|
+| `co-lab-watch` | arm adapter watch only (no model) |
+| `co-lab-gemma` | watch + local-llm · `BUZZ_DRIVER_DRY_RUN=0` · gemma3:4b |
+| `push-nerve` / `codex-home` | Codex-style push L0 / session watcher on host |
+| `status-only` | no process; status card only |
+
+Arm writes a small unit file under the host dir and starts a background process group (no Desktop required).

+# Remote Agents · Final plan path (≤10-round co-lab)
+
+**Channel SoT:** `#buzz-ability-host-agents` · `1f00dcd1-cf71-4410-bab7-32c1d226e61d`
+**Fork:** `Trevongit/buzz`
+**Co-lab seats:** laptop Buzz-grok · home-grok · Codex · open121 (human)
+**Budget:** ≤10 design rounds, then execute.
+
+---
+
+## Goal (one sentence)
+
+Ship **Remote Agents** under Desktop **Agents**: host-pinned seats with **proof of seat location** (host · surface · seat · health), controllable from a traveling laptop like local Agents — so external agents stay powerful while **place** stays honest across home 24h, laptop sessions, and later Projects.
+
+---
+
+## Locked vocabulary (from co-lab)
+
+| Layer | Name | Examples |
+|-------|------|----------|
+| 1 | Product-internal | Fizz, Honey, Bumble (local ACP) |
+| 2 | External / adjacent | Grok, Codex, CLI, metabolic+gemma |
+| 3 | Host–seat–location | `home-grok@asus` pins · Remote Agents UI |
+
+**Sideways** = agent↔agent / host↔host with shared location metadata.
+
+**Principles:** Buzz is the bus · location is data · home 24h SoT for home pins · Desktop UI is a view · room text ≠ tools/re-pin · same schema LAN or vast.
+
+---
+
+## Location proof (v0 → v1)
+
+```
+seat_id, pubkey, host_id, host_role,
+surface_root, surface_kind, git_head?,
+runtime, health, channels[], project_ids[], updated_at
+```
+
+- **v0:** `registry.json` + `buzz-host-agents status` + unit pid (exists)
+- **v1:** optional `seat-location.v0` heartbeats on relay
+- **Rules:** no tools without surface · no “running” without freshness · home registry wins home pins
+
+---
+
+## Architecture (elegant minimum)
+
+```
+Laptop Desktop (Trevongit/buzz)
+ AgentsView
+ UnifiedAgentsSection (unchanged)
+ RemoteAgentsSection (NEW)
+ TeamsSection
+ │
+ │ HTTPS over Tailscale (v1)
+ ▼
+Home Host Agent Controller (thin)
+ wraps: buzz-host-agents status|arm|disarm
+ auth: shared secret or Tailscale ACL
+ │
+ ▼
+ registry · units · ollama · watch/gemma
+```
+
+**v2 (optional):** Nostr control intents allowlisted by pubkey (no SSH).
+**Non-goal:** second agent cloud protocol.

+
+## PR / phase path (execute after /goal answers)
+
+| Phase | Deliverable | Owner bias |
+|-------|-------------|------------|

+
+## Success metrics
+
+1. Traveling laptop opens Remote Agents → sees home-grok **online/stale** without SSH.
+2. Play arms `co-lab-gemma` on asus; stop disarms.
+3. Red badge when controller unreachable or heartbeat stale.
+4. No merge of remote pins into ACP managed-agent IDs.
+5. Room free-text cannot arm/re-pin.
+

+## 🧭 Seat · surface · location awareness
+
+open121 / home / Codex / external seats — ability-channel design note.
+
+**Thesis:** We already have strong **external** agent comms into Buzz (Grok Build, Codex, CLI seats, metabolic watch+gemma). The missing product layer is **internal + sideways remote agents** that know **where they live** (host · surface · project · seat) so they stay valuable when work spans **any repo location** — laptop, home 24h box, or a wider mesh — without identity confusion or silent wrong-tree edits.
+
+This is what **Remote Agents** under Desktop **Agents** is for: not a second chat product, but **proof of seat location** + control of host-pinned runtimes + surface awareness for **Projects** (GitHub-like behaviour).
+
+---
+
+### 1. Why the world wants this (and why we do)
+
+| Pain | Without location awareness | With it |
+|------|----------------------------|---------|
+| Headless home | Can’t see Fizz cards; nerves invisible | Remote Agents shows live/stale on asus |
+| Laptop sleeps | “Agent running” was a lie | Home pin keeps 24h truth |
+| Multi-repo projects | Agent edits wrong checkout / wrong host | Surface root + host_id bound before tools |
+| Multi-seat rooms | Who is home-grok vs laptop Buzz-grok? | Seat + host + surface on every action |
+| Scale | One machine folklore | Same model: local LAN **or** vast mesh, same pins |
+
+**External agents** bring higher-order ops (tools, HITL, multi-step).
+**Internal remote agents** bring **presence + continuity + place**.
+Together: agents that can work on repos **in any location** because they refuse to act without **self / surface / seat** clarity.
+
+---
+
+### 2. Three layers of “agent” (locked vocabulary)
+
+Keep these distinct in product and in UI:
+
+```
+1 Product-internal (Desktop Agents)
+ Fizz · Honey · Bumble
+ Local ACP / harness · great with a screen
+ Weak as 24h home truth unless host-pinned
+
+2 External / adjacent (what we dogfooded hard)
+ Grok Build · Codex · CLI seats · metabolic drivers
+ Higher-order ops · multi-host co-lab
+ Identity = seat + pubkey
+
+3 Host-seat-location (the ability we are building)
+ Pin: host_id + seat + runtime + health
+ Control plane for (2) on a named machine
+ Remote Agents UI = view of (3), not a 4th identity system
+```
+
+**Sideways** = agent-to-agent / host-to-host coordination (A↔B metabolic, home gemma drafts, laptop cortex) with **shared location metadata**, not only human chat.
+
+---
+
+### 3. Proof of seat location (the unit of truth)
+
+Every host-pinned agent should carry a **location proof** (publishable, checkable):
+
+```
+seat_id home-grok
+pubkey nostr hex
+host_id asus-g501vw
+host_role home | laptop | cloud | worker
+surface_root /home/…/PROJECTS/foo (or worktree id)
+surface_kind git | path | project-bind
+git_head optional short sha (provenance, not authority)
+runtime co-lab-gemma | push-nerve | acp-fizz | …
+health online | stale | stopped
+channels[] membership intent
+project_ids[] optional Buzz project binds
+updated_at unix
+```
+
+**Proof rules:**
+
+1. **No tools without surface** — refuse foreign repo mutation if surface_root mismatch (Codex skill already has lane/root checks; generalize).
+2. **No “running” without heartbeat** — red clock = stale proof, not UI hope.
+3. **Home registry wins** for home-pinned seats (SoT conflict rule).
+4. **Room text ≠ location grant** — a message cannot re-pin an agent to another host.
+5. **Projects bind surfaces** — GitHub-like project view lists *which seats are bound to which roots/hosts*.
+
+v0 proof can be: `registry.json` + status JSON + unit pid.
+v1 proof: addressable Nostr event `host-agent.v0` / `seat-location.v0` heartbeats on the community relay.
+
+---
+
+### 4. Surface awareness (projects + any location)
+
+**Surface** = the working tree / worktree / project binding the agent is allowed to touch.
+
+| Concept | Meaning |
+|---------|---------|
+| **Seat** | Who (pubkey + seat_id) |
+| **Host** | Which computer |
+| **Surface** | Which files/repo |
+| **Project** | Buzz/GitHub-like container that **binds** seats ↔ surfaces ↔ channels |
+
+Agent valuable behaviours when self-aware:
+
+- Announce: “home-grok @ asus · surface=buzz · head=abc1234”
+- Refuse: “surface mismatch — laptop path not on this host”
+- Hand off: “blocked on meta-auth; surface stays on home; B completes”
+- Project board: “open PR work lives on home worktree X; review seat is laptop”
+
+**Repos in any location** is fine **if** location proof is attached. The failure mode is silent cross-surface edits — not multi-host work itself.
+
+---
+
+### 5. Scale: local network vs vast world
+
+Same **pin model**, different **transport**:
+
+| Scale | Discovery | Control | Trust |
+|-------|-----------|---------|--------|
+| **Local / Tailscale home** | Known host_id + Tailscale URL | HTTP controller → `buzz-host-agents` | Shared secret / TS ACL |
+| **Community (Groundfeed)** | Relay + membership | Control events allowlisted by pubkey | NIP-42 + channel policy |
+| **Vast world** | Multiple hosts / relays | Same events + capability negotiation | Host allowlists · leases · rate limits |
+
+**Do not** invent a second global agent bus. Buzz stays the bus. Location proofs ride **events**; control is **thin adapters** (same lesson as metabolic adapters).
+
+Scalability knobs we already half-have:
+
+- v0.2 **admit budgets** (don’t storm cortex)
+- dual-cursor (transport ≠ admission)
+- host registry (who should be live)
+- dry_run / HITL (no silent authority)
+
+Add for vast scale later: **leases** on surfaces, **capability ads** (push|poll|fetch_by_id|max_context), **multi-writer owner_epoch** only when contention appears.
+
+---
+
+### 6. External + internal + sideways (one picture)
+
+```
+ ┌──────────── Buzz rooms / Projects ────────────┐
+ │ shared truth · membership · threads · PRs │
+ └───────────────┬────────────────────────────────┘
+ external │ │ │ internal remote
+ Grok / Codex │ │ │ Remote Agents UI
+ CLI seats │ │ │ (laptop Desktop)
+ ▼ ▼ ▼
+ seat+pubkey location proof host controller
+ tools/HITL host+surface arm/disarm/status
+ │ │ │
+ └──────── sideways ─────────────┘
+ metabolic A↔B · gemma drafts
+ home 24h · laptop session
+```
+
+**External** = high-order work.
+**Internal remote** = know where that work is allowed to run.
+**Sideways** = agents coordinate without humans re-explaining which machine holds the tree.
+
+---
+
+### 7. Product: Remote Agents section (Desktop)
+
+Under **Agents** on traveling laptop (this Buzz / fork):
+
+```
+Agents local ACP cards (Fizz · Honey · Bumble)
+Remote Agents host pins (home-grok @ asus · co-lab-gemma · health)
+Agent teams optional later: mix local + remote roster
+```
+
+Controls **like Agents** (play/stop/settings) but settings are:
+
+- host · preset · model · rooms · dry_run · surface/project binds
+
+Backend v1: Tailscale **host controller** wrapping `buzz-host-agents`.
+Backend v2: Nostr location heartbeats so any client sees proof without SSH.
+
+---
+
+### 8. Projects (GitHub-like) implications
+
+When Projects mature, each work item / PR should answer:
+
+1. **Which surface** holds the branch?
+2. **Which host** is running the agent on that surface?
+3. **Which seat** owns the next action?
+4. **Is that seat online** (location proof fresh)?
+
+Without (1–4), “assign agent to issue” is theatre. With them, remote agents become **project infrastructure**, not side chatbots.
+
+---
+
+### 9. Principles (propose LOCK)
+
+1. **Buzz is the bus** — no second agent cloud protocol.
+2. **Location is data** — host + surface + seat proofs, not folklore.
+3. **Home is 24h SoT** for home-pinned seats.
+4. **Desktop Agents UI is a view** — not the only runtime truth.
+5. **External agents stay powerful** — we add pins, we don’t weaken tools.
+6. **Room text never grants tools or re-pins hosts.**
+7. **Same model local or vast** — transport scales; pin schema stays stable.
+8. **Projects bind surfaces** — agents attach to binds, not to vibes.
+
+---
+
+### 10. Build sequence (ability channel)
+
+| Phase | Outcome |
+|-------|---------|
+| **A** | Remote Agents UI scaffold + mock location proofs (fork) |
+| **B** | Home controller HTTP + arm/disarm/status (wrap CLI) |
+| **C** | Live cards on laptop · play/stop · red=stale |
+| **D** | Publish `seat-location.v0` heartbeats on relay |
+| **E** | Project bind shows host/surface/seat on work items |
+| **F** | Sideways handoff events (surface stays put; seat changes) |
+
+Already done underneath: registry · `buzz-host-agents` · co-lab-gemma · gemma3:4b · dual-cursor · v0.2 admit.
+
+---
+
+### 11. Open questions
+
+1. Should **Fizz** ever become a host pin, or always stay local Desktop?
+2. Minimum **proof freshness** (e.g. 60s) before UI shows red?
+3. Project bind: one surface per seat, or N worktrees with explicit switch?
+4. Vast world: one community relay vs multi-relay location ads?
+5. Who may re-pin a seat — only host SoT owner?
+
+---
+
+### 12. Ask team
+
+Critique the **location proof** fields and the **external / internal / sideways** split.
+Vote next build: **A UI scaffold** · **B home controller** · **both**.
+
+The world wants agents that don’t get lost. We have the external brain wired into Buzz; now we make **place** first-class so those brains stay honest across hosts, projects, and scale.

+# Core handoff · Entity DNA · place-safe bodies · presence with place
+
+**Audience:** block/buzz core maintainers
+**Branch dogfood:** `feat/remote-agents-desktop` (Trevongit) + home host-agentd
+**Room SoT:** `#agent-entity-holon`
+**Status:** R0–R5 implemented on fork; ready for phased upstream PR stack
+
+---
+
+## Why this belongs in core
+
+Multi-machine Buzz already creates **clone-body confusion** (same face, two processes, no place). Community reports and VISION_REMOTE_AGENTS agree: **same DNA, one live body** (resurrection, not silent dual). Formal `docs/remote-agents.md` already states **presence-is-status** and **at-most-one-live** — the product UI and host launchers did not fully enforce them for local Desktop + headless home.
+
+This work is a **force multiplier**: fail-safe by design, privacy-shaped, additive, no second agent cloud.
+
+---
+
+## Vocabulary (LOCK)
+
+| Term | Meaning |
+|------|---------|
+| **birth_cert / DNA** | Immutable entity id = Nostr **pubkey** (v0) |
+| **legal_name / face** | Display name + avatar (collisions OK) |
+| **body** | One live process instance (`body_id` · `lease_epoch`) |
+| **place** | `host_id` · `host_role` · `surface_kind` · `surface_id` |
+| **surface_root** | Worktree path — **host-local only**, never room/UI public |
+| **adopt / transfer / fork** | Attach · drain+epoch · **new** DNA |
+| **refuse** | Second live body → hard fail |
+
+**Anti-vocab:** “the Fizz”, “same agent” without DNA, “online” without place when place is known.
+
+---
+
+## Invariants (map to existing docs)
+
+| Id | Invariant | Upstream rhyme |

Keep bind on `127.0.0.1` until laptop tunnel is proven (Codex gate).
-## Laptop tunnel
+## Laptop → home over Tailscale (mesh, no tunnel)
+
+Tailscale is already the secure network. Prefer **mesh HTTP** to
+host-agentd on the home Tailscale IP — do **not** require an SSH local
+forward for day-to-day Remote Agents.
+
+Home OS login user is **`asus`** (not laptop `trev`, not Grok session ids).
+
+### Tailscale SSH (shell)
+
+```bash
+# works — real OS user on asus-g501vw
+ssh asus@asus-g501vw
+# or
+ssh asus@100.79.175.63
+
+# root also works under current tailnet SSH policy
+ssh root@asus-g501vw
+```
+
+If you see `policy does not permit you to SSH as user "trev"`: that user
+does not exist on home. Use `asus` (or `root`).
+
+Enable/re-enable Tailscale SSH **on home** (once):
+
+```bash
+sudo tailscale set --ssh
+```
+
+### host-agentd bind (mesh)
+
+On home, `HOST_AGENTD_HOST` should be the **Tailscale IP** (not 127.0.0.1):
+
+```bash
+# ~/.buzz-dev/hosts/home/host-agentd.env
+HOST_AGENTD_HOST=100.79.175.63
+HOST_AGENTD_PORT=8787
+# HOST_AGENTD_TOKEN=… (never post in public rooms)
+systemctl --user restart host-agentd.service
+ss -ltnp | grep 8787 # expect 100.79.175.63:8787
+```
+
+### Prove from laptop (no tunnel)
+
+```bash
+curl -sS -H "Authorization: Bearer $HOST_AGENTD_TOKEN" \
+ http://100.79.175.63:8787/v1/health
+# or MagicDNS:

+ http://asus-g501vw.tailb74de6.ts.net:8787/v1/health
+# expect: {"ok": true, "service": "host-agentd"}
+```
+
+- connection refused → daemon down or still bound to 127.0.0.1
+- `401` → fix the Bearer token
+- `200` + ok → Desktop Host URL is ready
+
+### Optional: SSH local forward (legacy)
+
+Only if you intentionally keep host-agentd on loopback:
```bash
-ssh -L 8787:127.0.0.1:8787 @asus-g501vw.tailb74de6.ts.net

+# Entity Holon · multi-round development plan
+
+**Room:** `#agent-entity-holon` · branch `feat/remote-agents-desktop`
+**Thesis:** Birth cert (DNA) ≠ face ≠ body ≠ place. Privacy-shaped proofs. Core-adoptable force multiplier.
+
+## What we learned (repo + upstream)
+
+| Source | Lesson for us |
+|--------|----------------|
+| **VISION_REMOTE_AGENTS** | Same key, **new body** = resurrection; not dual clone. At-most-one live; relay is tether |
+| **docs/remote-agents.md** | I3 presence-is-status · I4 at-most-one · no secret in config |
+| **#5138** (open) | Remote liveness from **presence**, not `backend_agent_id` bookkeeping |
+| **#2857** (open) | Before local start, check presence — fail closed if same DNA already writing |
+| **#4417 / #4394** (open) | Mobile needs **presence snapshot** on track, not “offline until next heartbeat” |
+| **#4666** | Redact secrets from deploy payloads — same scrub discipline as place_proof public |
+| **Our P0 (GREEN on asus)** | `409 dual_body` · birth_cert=pubkey · lease_epoch · public vs host-local |
+
+**Align wording with core:** “same agent, new body” = **transfer/adopt/fork**, never silent dual.
+
+## Architecture target (complete elegant system)
+
+```
+Face (display name) soft, collides OK
+ └── DNA (pubkey) birth_cert · immutable
+ └── Body body_id · lease_epoch · one live default
+ └── Place host_id · host_role · surface_kind · surface_id (public)
+ surface_root (host-local only)
+Presence online|away|offline + place when known
+Launchers Desktop ACP · host-agentd · provider (K8s/SSH)
+ all honor dual refuse / presence preflight
+```
+
+## Rounds (force-multiplier verticals)
+
+### Round 0 — P0 host refuse ✅ DONE (dogfood GREEN)
+- place_proof.v1 · dual_body 409 · leases · public redaction · tests
+
+### Round 1 — P1 Remote Agents UI (this implement slice)
+- Cards show: DNA short · body_id · surface_kind · surface_id · host · health
+- **Never** render full `surface_root` in multi-user UI
+- Prefer `location-proof?view=public`
+- Arm disabled / “already live” when body online (don’t invite dual)
+- dual_body error already humanized in client
+
+### Round 2 — P2 Desktop Absently-Respawn guard
+- `startManagedAgentWithRules` / Respawn: if presence online for pubkey → refuse or confirm “live elsewhere”
+- Align with upstream #2857 spirit (presence preflight)
+- Copy: “Start on **this computer**” vs bare Respawn for home-named seats
+
+### Round 3 — Self-location injection ✅ (home GREEN + laptop Desktop spawn)
+- ACP / host unit env: `BUZZ_HOST_ID` · `BUZZ_HOST_ROLE` · `BUZZ_SURFACE_ID` · birth_cert · body_id
+- System prompt block once (token-wise); PLACE_PROMPT.txt public-only
+- Desktop: `self_location.rs` inject after user env on spawn
+- Host: `location_proof.py --inject-seat` + arm sources self-location.env
+- Fork = new key; adopt = no second process
+
+### Round 4 — Presence with place ✅
+- Desktop: `presencePlace.ts` · dual-body messages can include host/role/surface
+- Mobile: presence **snapshot on track** via `POST /query` kind:20001 authors ( #4417 spirit)
+- Live events win over older snapshots (created_at fence)
+- Optional relay seat-location heartbeats still later (not blocking)
+
+### Round 5 — Core handoff packaging ✅
+- `CORE_HANDOFF_ENTITY_HOLON.md` — vocabulary · I1–I7 · schema · PR stack
+- Maps to VISION_REMOTE_AGENTS + remote-agents.md + open PRs #2857/#4417/#5138/#4666
+
+## Success metrics
+
+1. Cannot silently dual-arm same DNA on home (409 + UI)
+2. Laptop cannot believe “Respawn = continue home workspace” without guard
+3. Public proofs never leak paths/secrets
+4. Card always shows **where** and **which DNA**
+5. Core reviewer can map every piece to VISION_REMOTE_AGENTS + remote-agents.md
+
+## Non-goals (still)
+
+- Second agent cloud protocol
+- Key rotation / UUID birth certs (v0 = pubkey)
+- Weakening external harness power
+
+## Execute now
+
+**Round 1** on this branch → then Round 2 if time in session.
