5	+	- Added: the project skeleton (#1). A Cargo workspace in Oxygen's shape (`spectra-core`, `spectra-mcp`, `spectra-api`, `radar` and the `spectra` binary), Oxygen pinned under `deps/oxygen` for identities and signatures, `make check`, the changelog check, `spectra version [--json]` with the build identity, and `scripts/deps-check.sh` to keep Spectra buildable by the vendored OxygenFlow image.

3	+	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.
4	+
5	+	## Rules
6	+
7	+	- 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.
8	+	- Tests are hermetic: a temporary data directory, a temporary socket, port 0; never `~/.local/share/spectra`, `~/.config` or the network.
9	+	- Gate every commit on `make check` (changelog, fmt, clippy with warnings as errors, tests).
10	+	- Every code change adds a CHANGELOG.md line under `## Unreleased`, or sets `NO_CHANGELOG=1`.
11	+	- Never weaken a security goal of spec §5 to make a test pass.
12	+	- Never act as Andy: owner-only steps (delegating to an agent key, the acceptance run) wait for him.
13	+
