**Date:** 2026-06-11 **Bead:** `fe7fbaf5-4c47-43b6-be1b-2f6ca15e8bfa` **Modality:** CE (Claude Code extension). Written incrementally per chat-log discipline; user prompts verbatim.
**Stephen (verbatim):** > start-bead *(interrupted by user before the scaffold ran — the follow-up prompt supplied the topic)* **Stephen (verbatim):** > lets design how a bead as agent is the handler for a webdav surface in the browser and with an os process using anthropic api key **Claude (summary):** Surveyed the bead protocol ([.agents/beads.md](https://redfish.acequia.io/guerin/.agents/beads.md)) and today's beads; identified the direct upstream threads — [agentify-bead d9dfa5e4](https://redfish.acequia.io/guerin/.agents/d9dfa5e4-3c92-4216-bd53-13b520c59a5e/about.md) (agent.md/agent.json declaration standard, ratified today) and [hey-you-its-me ec4d09d8](https://redfish.acequia.io/guerin/.agents/ec4d09d8-7f06-41d3-80fe-80aeaedba680/2026-06-11/notes/00-concepts.md) (`acequia.json` runtime routing) — plus the [5595c7f1 agent.md prototype](https://redfish.acequia.io/guerin/.agents/5595c7f1-4621-437c-a4ae-7902b640f0e8/agent.md). Loaded the Claude API reference (claude-api skill) for the OS-process side. Scaffolded this bead and drafted the core design note: [bead-as-webdav-handler.md](https://redfish.acequia.io/guerin/.agents/fe7fbaf5-4c47-43b6-be1b-2f6ca15e8bfa/2026-06-11/notes/bead-as-webdav-handler.md). Key design moves (full text in the note): 1. **Handler = third layer** after declaration (`agent.json`) and routing (`acequia.json`): `handle(verb, path, headers, body, caller) → response`. 2. **Two lanes**: synchronous (live verb answer) and asynchronous (dock `PUT` → `202 Accepted` + `Location`); store-and-forward is the degenerate handler, so the surface never refuses. 3. **Liveness ladder**: static origin → service worker → OS animator; same contract, `acequia.json` dispatches to the most-alive runtime energized. 4. **Browser/SW runtime**: SW `fetch` = duck-typing collapse point; runs bead-local `handler.mjs`; inherits the *user's* authority (per-caller, Plan-9); **no Anthropic key in the browser** — cognition via scoped LLM-proxy token from the AS-role mesh or delegation to an animator; no state in the worker (idle-kill = apoptosis by design). 5. **OS animator**: one daemon animates many beads (mayordomo shape). Bead root files map 1:1 to Claude API constructs — `agent.md` = system prompt (= stable prompt-cache prefix), `skills/` = Skills, `names.json` = import map, `uploads/` = message queue, `chats/` = transcript; Managed Agents named as the hosted analogue, ours self-sovereign. Tool surface = WebDAV verbs as dedicated tools with the write-scope gate (own subtree + foreign docks) enforced in the harness. Two credential planes: `ANTHROPIC_API_KEY` (cognition, env only) vs scoped WebDAV chain token (namespace) — independently revocable apoptotic signals. 6. **Charge = budget**: spend only on demand-caused ticks; no references → no spend → decay to static face; budget exhaustion is an orderly apoptosis input. 7. Proposed `agent.json.handler` block (`browser.module` + integrity, `process.animator` by reference, `fallback: "dock"`). 8. Five open questions left for Stephen: dock-only vs POST ingress; handler-code trust gate; one-animator-many-beads confirmation; LLM-proxy path for browsers; budget-ledger location.
**Stephen (verbatim):** > be careful with words like never. especially on your statement > " but with three hard constraints: no Anthropic key in the browser, ever " > > you must have been biased to traditional and not loaded enough acequia context **Claude (summary):** Correction accepted — the draft imported the traditional multi-tenant-web taboo ("browsers are hostile territory, keys belong on servers"). The draft's own analogy refuted it: it called the API key "the same class as the user signing key," and the signing key — the root of the acequia trust system — already lives browser-side and mints chain tokens client-side. A parciante's browser is a first-class node. Amended the design note: §4 constraint 1 rewritten as **"credential scope is the constraint, not the runtime"** (with the correction recorded inline); the placement rule is blast-radius × revocability applied uniformly — scoped/spend-capped key, short-TTL minted token, or zero-credential delegation, with the genuine contraindication being a *broad* key in an origin executing *foreign* `handler.mjs`. §3 ladder, §5 credentials table (now "credentials live in nodes, not in the commons"), and §8 Q4 (default browser-cognition path, three options) updated to match. Feedback saved to persistent memory.
*(2026-06-12)* **Stephen (verbatim):** > as many beads will be relatively simple, local llms with training can replace cloud Ais **Claude (summary):** Added the **cognition ladder** to the design note (§5, new subsection) — orthogonal to the §3 liveness ladder: rung 0 deterministic `handler.mjs` → rung 1 small local model (Ollama/llama.cpp on node; WebGPU/WebLLM in browser) → rung 2 **distilled local model trained on the bead's own corpus** (`chats/` as verbatim ground truth + `notes/` + `skills/` + dock traffic) → rung 3 cloud frontier via the animator's key. Key moves: identity persists across brain transplants (callers negotiate with the surface, not the weights; distilled weights are themselves a resource at a path); **escalation, not selection** (cloud key becomes the escalation credential, not the default); charge=budget refines to per-rung apoptosis (cloud-dormant yet locally responsive); rungs 0–2 need no cognition credential at all, so open Q4 gains option (d) — in-browser local model, zero keys. Proposed `agent.json.cognition` block (rungs + escalation policy). Added open question 6: escalation-policy ownership, distilled-weight location/versioning/attribution (advanced wave applies to the model, not just the answers), and the distillation threshold (when training beats prompting).
*(Later 2026-06-12 — after first `/bead-sync` to the canonical URI)* **Stephen (verbatim):** > for now add a anthropic api and gemini api as options as the handler. in effect this is a bring your own key but acequia.js should be helping with that. **Claude (summary):** Cloud rung made **provider-plural and BYOK**: Anthropic (`claude-opus-4-8`) + Gemini (`gemini-2.5-pro`) as the two options for now. `agent.json.cognition` sketch updated to a `providers` array — the bead declares which providers it *can use*, never keys; key supply is the animating node's business. New §5 subsection **"BYOK and acequia.js"**: acequia.js extends its namespace-plane custody machinery (`acequia.chains`, SW ambient auth, scoped writePaths, TTL) to the cognition plane — per-node keystore (`acequia.keys.set({plane:"cognition", provider, key, scope})`), provider adapters giving one `tick()` over Anthropic Messages/tool-use and Gemini generateContent/function-calling, narrowest-key preference (workspace-scoped/spend-capped), handler code receives a capability object not a key string, and mesh-minted `…/auth/llm` tokens are just another keystore entry. Open Q4 partially bound: BYOK-via-acequia.js is the for-now default; still open whether the mesh grows the minting endpoint and when in-browser local models overtake BYOK for simple beads. Dogfooded the cognition block into this bead's own `agent.json`.
**Stephen (verbatim):** > this are the "desire paths" between webdav-beads > https://gsd.live/people/stephen-guerin/images/stigmergic-web.png **Claude (summary):** Viewed the image (hand-drawn hills, devices as nodes, worn dirt trails between them; `HTTP` / `WebDAV over WebRTC` as trail surfaces; `local policy` posted at gates; acequia.org and gsd.live valleys). Extracted [2026-06-12/notes/desire-paths-between-beads.md](https://redfish.acequia.io/guerin/.agents/fe7fbaf5-4c47-43b6-be1b-2f6ca15e8bfa/2026-06-12/notes/desire-paths-between-beads.md): inter-bead traffic wears paths (stigmergy — coordination via traces in the shared medium), fusing polarized-links + Hubler wires (a desire path = a self-assembling wire in grass) + paths-as-event-bus. Bound into the handler design as the **stigmergic duty**: every tick deposits a readable trace; escalation = the fork wearing in, distillation = paving the desire path (a bead's distilled model is its desire paths *compiled*), leases = re-walking, apoptosis = trail fading, `acequia.json` = the local-policy sign at the gate. Sharpened open Q5: the ledger is the pheromone layer, so it must be namespace-readable by other walkers or the web is merely metered, not stigmergic. New sub-question: trace granularity + decay rate (the medium's relaxation time as a design parameter).
**Stephen (verbatim, two messages sent while the previous turn was in flight):** > in the main agents.md for beads, we should include a sync'ing background task for the chats that mounted it > only if the chat has advanced and added to the bead. **Claude (summary):** Amended the canonical protocol [`.agents/beads.md`](https://redfish.acequia.io/guerin/.agents/beads.md) with a new section **"Background Sync While a Chat Holds a Bead (dirty-gated)"**: a chat that mounted a bead launches `/bead-sync` as a background task at the end of any turn that *advanced* the bead — strict dirty gate (writes this turn, not reads), once per advancing turn (not per file write), additive mode, background so chat flow continues; rationale tied to the stigmergic commons (siblings walk the canonical URI, not the local origin). Reconciled `.ai/skills/bead-sync/SKILL.md`, which previously said "never automatic": the explicit command remains, and the dirty-gated end-of-turn task is now the one sanctioned automatic cadence. Dogfooded immediately — this bead was dirty (BYOK + desire-paths additions since first sync), so a background sync was launched at end of turn. Note: `.ai/beads.md` (the divergent sibling copy) not touched — whether it receives the same section remains the open item flagged in d9dfa5e4.
**Stephen (verbatim):** > note the pattern for token management and you being to mint them if they are your > https://acequia.io/documentation/platform/token-management-api.md **Claude (summary):** Fetched the live doc (not in the local origin). The load-bearing pattern: **any valid token holder can mint sub-tokens** via `POST /auth/create-token` — not just owners — with strict **attenuation** (sub-scope ⊆ caller's effective scope, escalation → 403; expiry capped to caller's remaining lifetime), **chain extension** rather than independent tokens (default max depth 4), **cascade revocation** (revoking a parent invalidates all descendants via chain verification), `reuseId` renewal, and a 100-mints/parent/hour backstop. Added §5 subsection **"The handler is also a minter"**: the animator is a token-granting node for its own subtree — (1) equip a caller (202 + Location + a read token scoped to exactly the answer path), (2) equip what it hatches (attenuated `writePaths` for spawned sub-beads — *raised becomes raises*, authority can never exceed the parent's), (3) self-renew short-TTL working tokens via `reuseId`. Lifecycle mapping: chain revocation = apoptotic cascade (offspring cannot outlive the parent's mandate); expiry-attenuation = TTL apoptosis by construction; mint rate-limit = anti-cancer guard; depth cap bounds delegation before re-grounding in a user-signed root. Plane symmetry noted: `/auth/create-token`/`acequia.chains` = namespace mint; scoped BYOK key in `acequia.keys` = cognition analogue; Q4's `…/auth/llm` would complete it. Also recorded Stephen's standing authorization: the CE agent begins minting scoped tokens for resources it owns (its bead subtrees) rather than always riding the broad bearer token. names.json + memory updated; dirty-gated background sync launched at end of turn per the new beads.md rule.
