David Charlot b838b86a8b joule-code: stand up the Joule Code standard (v0.1.0 draft)
Joule Code is the coding cargo class of the substrate: a coding operation —
an edit, refactor, or generated function — is a content-addressed, signed
transition over a source tree, resolved through the energy-tiered cascade
(L0 Cache → L1 Lawful → L2 Embed → L3 Model → L4 Wire, stop-at-first-close)
with a signed JWP receipt (measured + estimated µJ, honest Provenance) per
operation. The agent schema is JouleClaw; L4 frontier agents are reached over
ACP with the credential held by the vendor's own client — no protocol token,
no required contact with any single company.

Stands up the standard to the family schema:
- README, SPEC.md (RFC-2119 normative), dual licence (Apache-2.0 code /
  CC-BY-4.0 spec), ROADMAP, CONTRIBUTING, CHANGELOG.
- spec/: cargo (the coding-operation type), cascade (the tier binding),
  receipt (the JWP energy record), collab (federated, interface-level/Research).
- vocab/LEXICON.md.
- conformance/v1/: C1 content-addressing, C2 signing, C3 receipt, C4 cascade
  vectors + VERSIONS + regeneration; real Ed25519 RFC-8032 KATs, derived
  fields regenerated against the reference library.
- joule-code-rs/: lean reference library (schema, cargo, receipt, cascade,
  conformance). cargo test --workspace passes; the conformance harness runs
  11 pass / 0 fail / 7 skip (derived fields pending regeneration).

Single-endpoint operation is the v0.1 surface; federated collaboration is
specified at interface level and classified Research. Registers the standard
in the family README.

Joule Code roadmap

Where the standard goes after v0.1.0. The reference library in joule-code-rs/ is a multi-crate Rust workspace; the flagship consumer is the agent-zed editor.

v0.1.0 (current)

  • Coding-operation cargo, content addressing, deterministic CBOR, signing (§2–§4).
  • The receipt: estimated energy with Estimator provenance, JWP-signed (§6).
  • The cascade interface and the conformance suite C1–C4 (§5, §8).
  • Single-endpoint operation only; collaboration is interface-level (Research).

Near-term (v0.2)

  • Measured energy. Bind the receipt's measured_uj / HwShunt path to real hardware interfaces (RAPL on Linux, SMC/IOReport on Apple Silicon) via JouleClaw's energy + calibration crates. Promote §6 measured path from Engineering toward Solid where the platform delivers it.
  • Cascade lower tiers. Land real L0 (content-addressed op cache) and L2 (embedding + hybrid retrieval) stages so frontier calls (L4) are genuinely the last resort, not the first.
  • Per-task routing. Choose the closing tier and the L4 leg per request from intent + budget, recorded in the receipt.

Mid-term

  • Federated collaboration (Research → Engineering). Promote spec/collab.md from interface-level to a conformance-bearing binding: coding operations as Smart Byte envelopes, lockstep replication, CommunicationOS transport for session and presence, RemoteOS for shared sessions. Add a conformance/v1/lockstep_vectors.json-style pack when the binding stabilizes.
  • Post-quantum signatures. Exercise the one-byte algorithm identifier (§2) with a PQ successor alongside Ed25519.

Non-goals

  • A protocol-level token. There will not be one.
  • Reimplementing vendor agent authentication. Frontier agents (L4) are reached through the vendor's own logged-in client; the credential never enters the protocol.
  • Reimplementing codecs, editors, or model runtimes. Joule Code composes existing standards (JouleClaw, Smart Byte, EOC, CommunicationOS, RemoteOS); it does not absorb them.
