# Sprint 1 plan: Spectra 0.1, Talk

Each loop iteration: pick the first unchecked item, implement it with tests, run the gated checks, commit with `oxy`, tick the box here with a one-line note, and commit again. Update `docs/spec.md` (and its changelog) whenever behaviour the spec describes changes. If an item cannot be finished in two iterations, note why under it and move on. The issues are on https://oxygenhub.io/projects/andymccall/7.

## Rules

- Never run `git init` in this directory or push this project anywhere but its `oxygenhub` remote. Commit with `OXY_HOME=~/.oxy-agents/claude oxy commit -m "..." PATHS..`, never with Andy's own key.

- Tests are hermetic: a temporary data directory, a temporary socket, port 0; never `~/.local/share/spectra`, `~/.config` or the network.

- Gate every commit on `make check` (changelog, fmt, clippy with warnings as errors, tests).

- Every code change adds a CHANGELOG.md line under `## Unreleased`, or sets `NO_CHANGELOG=1`.

- Never weaken a security goal of spec §5 to make a test pass.

- Never commit or push anything under `docs/prompts/` (Andy's prompts; ignored in `.oxyignore`). Name the paths in every commit.

- Never act as Andy: owner-only steps (delegating to an agent key, the acceptance run) wait for him.

## Items

- [x] #1 Project skeleton in Oxygen's shape — done 2026-11-02: workspace, deps/oxygen pinned, make check, deps-check (212 crates, all vendored).

- [x] #2 CI on OxygenFlow — done 2026-11-02: run #1 passed fmt, clippy, test, build with no image rebuild.

- [x] #3 The ledger — done 2026-11-02: chain, frozen envelope, HLC, signed checkpoints every 256 events, verify/check/rebuild; append 0.15 ms (release), 10,000 random events with rebuild and verify 1.3 s.

- [x] #4 Identities instead of tokens — done 2026-11-02: init, agent add (waits for the delegation), list, disable, identity show/refresh; Principals replay in verify; Authenticator (window, nonce, uid); write lock. Checked against the real `oxy identity delegate add`. The socket and its SO_PEERCRED arrive with #7, which uses the Authenticator.

## Log

- 2026-11-02 plan created; sprint adjusted to spec Draft 0.3 (identities and the ledger).

- 2026-11-02 #1 and #2 done (CI green on run #1); #3 done. Root disk was full: build trees go to /mnt/development/spectra-target (CARGO_TARGET_DIR).

- 2026-11-02 #4 done. Found and fixed while testing: a signed event's actor was not checked against its signer.
