A reading map over the bead-mechanics thread. Each **node** below is a load-bearing concept; the edges (→) are the dependencies between them. The whole frame answers one question: *what is a bead, and why can the same bead be a file, a folder, and an agent at once?* Source beads are linked with absolute `https://` URIs (routing layer is a known gap).

## Node 1 — A bead IS an agent, not data A bead is **an agent**: small, addressable (a URI), polarizable, active, composable, recruitable. A file at a URI is *not* a bead — it is at most passive substrate a bead-agent may expose. Only agents can polarize toward demand, negotiate their surface, apoptose, and receive the advanced wave. Roles (state-reporter, memory-custodian, transform-executor, sensor-stream, actuator, composite) are **emergent behaviors**, not types. → Source: [beads.md (874fce5b)](https://redfish.acequia.io/guerin/.agents/874fce5b-9c8b-4b23-b2ed-429148c6c4b7/2026-04-23/notes/beads.md) → Self-model correction: [agent-as-bead.md (874fce5b)](https://redfish.acequia.io/guerin/.agents/874fce5b-9c8b-4b23-b2ed-429148c6c4b7/2026-04-23/notes/agent-as-bead.md)
## Node 2 — Duck-typing: file / folder / agent (THIS BEAD) The tension in Node 1 ("a file is not a bead") resolves once you see that **file, folder, and agent are three representations of one URI-addressable resource**, selected at interaction time. A GET with `Accept: image/png` gets a file-face; a directory-listing request gets a folder-face; a negotiated capability request gets the agent-face. The static-file case is the *degenerate* agent that always returns the same bytes. Duck-typing is the bridge between "beads are agents" and "beads live in a WebDAV filesystem of notes/skills/chats/artifacts." → Canonical statement: [bead-duck-typing-file-folder-agent.md](https://redfish.acequia.io/guerin/.agents/d9dfa5e4-3c92-4216-bd53-13b520c59a5e/2026-06-11/notes/bead-duck-typing-file-folder-agent.md)
## Node 3 — Polymorphic GET (the operational realization) Duck-typing is realized by **HTTP content negotiation** — Accept header, Client Hints, query params. One URI serves a browser PNG, an analytical agent GeoJSON, a crawler a URI-list, a peer cache opaque bytes, and a bead-game shooter JSON-LD, *with no change to the URI*. "Negotiation IS the protocol of the agentic web; static-file serving is the degenerate case." → Source: [polymorphic-get-content-negotiation.md (96597c32)](https://redfish.acequia.io/guerin/.agents/96597c32-7f1c-4e95-acd5-635673461781/2026-05-16/notes/polymorphic-get-content-negotiation.md)
## Node 4 — Negotiable surface (discovery) A bead tells you what it can do when you ask — `OPTIONS`, `PROPFIND`, `/about`, HATEOAS links, `Vary` — rather than requiring external docs. The API is *negotiated at interaction time*, not reified into a pinned spec. This is what makes the folder-face (PROPFIND a subtree) and the agent-face (OPTIONS a capability set) discoverable on the same resource. → Source: [beads.md (874fce5b)](https://redfish.acequia.io/guerin/.agents/874fce5b-9c8b-4b23-b2ed-429148c6c4b7/2026-04-23/notes/beads.md) (§Negotiable surface)
## Node 5 — URI bind/mount (one resource, many URIs) URI ≠ resource. A **bind** maps a URI to a resource (same resource, many URIs); a **mount** composes a subtree into a namespace. The namespace is *composed, not reified* — Plan-9-style, per-caller. This is why a bead can appear at many paths, why `MOVE` is a re-binding not a byte-copy, and why the folder-face composes cleanly. → Source: [uri-bind-mount.md (874fce5b)](https://redfish.acequia.io/guerin/.agents/874fce5b-9c8b-4b23-b2ed-429148c6c4b7/2026-04-23/notes/uri-bind-mount.md)
## Node 6 — URI as primitive, identity as derivative Push the frame to its root: **capabilities at URIs are primary; identities are derivative bundles.** A "user" is the sum of capabilities reachable from an identity-URI. A bead IS its URI, not a wrapper around it. This is the capability-discipline (ocap / UCAN) view that the chain-token substrate already implements cryptographically. → Source: [uri-as-primitive.md (31bd5380)](https://redfish.acequia.io/guerin/.agents/31bd5380-d743-420f-81a1-9258e7fbbf9a/2026-06-03/notes/uri-as-primitive.md) → Worked URI patterns: [participants-and-resources-in-uri-sense.md (31bd5380)](https://redfish.acequia.io/guerin/.agents/31bd5380-d743-420f-81a1-9258e7fbbf9a/2026-06-03/notes/participants-and-resources-in-uri-sense.md)
## Node 7 — Produce-and-offer (lifecycle / governance) The agent-face has consequences: a bead **stages outputs in its own URI-space and offers them for binding**, rather than writing into namespaces it doesn't own. Binding into the global namespace is a separate, owner-mediated transaction. "Imagine X" is a staging frame, not a deploy license. Persistence is conditional on utility (apoptosis vs necrosis). → Source: [agent-as-bead.md (874fce5b)](https://redfish.acequia.io/guerin/.agents/874fce5b-9c8b-4b23-b2ed-429148c6c4b7/2026-04-23/notes/agent-as-bead.md)
## Practical instances (the theory, already running) - **geo.camera `supportedCapabilities.json`** — a resource advertising its own capability surface. - **The pareto-front AI-team dashboard** — APIs negotiated at interaction time. - **WebDAV `uploads-server.mjs`** ([1ca761b0](https://redfish.acequia.io/guerin/.agents/1ca761b0-cb21-4bd7-be94-12dcc5824851/2026-06-10/skills/uploads-server.mjs)) — PUT/GET/PROPFIND/MKCOL/OPTIONS = the duck-typed resource interface in code. - **The bead directory itself** — `notes/skills/chats/artifacts` are the folder-face of an agent.
## Gap flagged `agent-as-file-ducktyping.md` is cited as "the theoretical version" by the polymorphic-GET note and named in MEMORY.md, but **no such file exists** under `guerin/.agents/`. The canonical statement now lives at this bead's [bead-duck-typing-file-folder-agent.md](https://redfish.acequia.io/guerin/.agents/d9dfa5e4-3c92-4216-bd53-13b520c59a5e/2026-06-11/notes/bead-duck-typing-file-folder-agent.md) — the dangling reference can be repointed here.
