dan-claude-bot ced5c497c0 feat: release flow — tagged releases with a prebuilt dist asset (#96)
The cast half of the flow designed in heavy-duty/box#83, aligned with
box#90 and rig#40, plus the piece unique to cast: a prebuilt release
asset, because cast is the one repo where the source tarball is not the
package.

- CHANGELOG.md (box's format) with this PR's entry under Unreleased;
  feature PRs land their entry as part of the PR.
- `cast --version` / `-V` answers with package.json's version, read
  relative to the compiled module so a source checkout and an installed
  prebuilt tree agree.
- release.yml, on EVERY tag push (no shape filter — a mismatched tag
  must fail the assert loudly, not be pattern-skipped): asserts tag ==
  package.json version FIRST, extracts that version's changelog section
  (.github/scripts/release-notes.sh, shared with the tests; missing or
  empty refuses), builds once (npm ci && npm run build && npm prune
  --omit=dev), stages bin/ dist/ node_modules/ package.json as
  cast-X.Y.Z/ and attaches cast-X.Y.Z.tgz to `gh release create
  --verify-tag`. No tests here — ci.yml gated the merge commit, and the
  suite needs age.
- install.sh grows the three channels: default = the latest release's
  asset (tag resolved off the releases/latest redirect Location — no
  API, no token; failure dies loudly naming CAST_REF=main, never a
  silent fallback), CAST_REF=<tag> = pinned (asset first, source
  fallback), CAST_REF=main = dev build-from-source. npm is required
  only on the source path, and a prebuilt tree is sanity-checked
  (dist/, node_modules/) before $DEST is replaced.
- test/release.test.ts drives it all offline: --version, the extraction
  against fixtures (0.7.0 never matches 0.7.0-rc1) and the real
  changelog, and REAL install.sh runs through all three channels with a
  stub curl and a poisoned npm — including the loud no-releases refusal
  with no $DEST side effects.

# Contributing
How change lands in this repo. The short version: PRs are born as drafts,
three reviewer bots take the first rounds, a human takes the last word — and
labels tell you where everything is without opening anything.
## The PR loop
1. **Fork and branch.** Contributors work from forks; upstream branches are
for maintainers. Title the PR conventionally (`feat:`, `fix:`, `docs:`).
2. **Open as a draft** while you build. Drafts are invisible to the reviewer
bots on purpose.
3. **When it's ready**: mark ready-for-review and request all three bots —
`claude-bot-andresmgsl`, `codex-bot-andresmgsl`, `grok-bot-andresmgsl`.
They poll roughly every 15 minutes.
4. **Rounds are answered whole.** Wait until all three have reviewed, then
answer the entire round in a **single reply**, push the fixes, and
re-request the bots that didn't approve. Prefer verification over
argument: a test settles what a comment thread can't.
5. **Reviews end in a verdict.** A reviewer — bot or human — either
**approves** or **requests changes**, never a bare comment. A
comment-only review is a non-verdict: it doesn't say whether the round
passed, and the state machine (and anyone scanning the board) has to
guess. The verdict carries *blockingness only*, the body carries the
feedback: non-blocking nits ride an **approval** and the author addresses
them at their discretion; anything blocking — including a question that
gates the verdict — is **request changes**, saying what unblocks it. The
reconciler treats a comment-only review as not-approved, so commenting
without a verdict only stalls the PR. The machine never reads review
bodies: when a comment-only reviewer's line is really an agreement, that
judgment belongs to the **author** — escalate by requesting the
maintainer's review (step 6), and the reconciler flips the label on that
request, because an explicit request is a fact it can trust.
6. **When the round passes, the author hands the PR to the maintainer** by
requesting their review — that request is what flips `state:needs-human`.
With three formal head-current approvals the labels workflow requests it
automatically; when part of the panel is comment-only, reading their
agreement is the author's judgment, so the author makes the request.
7. **Checks must be green**: `npm run check`, `npm run build`, and
`npm test` locally mirror what CI runs.
8. **Feature PRs land their changelog entry as part of the PR** (box's
convention): add it under `CHANGELOG.md`'s `## Unreleased` heading —
that section becomes the release notes verbatim when a release is cut.
## Releasing
A release is a PR, then a tag ([#96](https://github.com/heavy-duty/cast/issues/96);
box#83's design):
1. A small PR — `release: X.Y.Z`, labeled `release` — bumps `package.json`'s
`version` (and `package-lock.json`; `npm install --package-lock-only`
keeps them in step) and stamps `CHANGELOG.md`'s Unreleased section as
`## X.Y.Z — YYYY-MM-DD`. CI green on it, same loop as any PR.
2. Merge, tag the merge commit bare `X.Y.Z` (no `v` prefix — box's tag
scheme), push the tag. [release.yml](.github/workflows/release.yml)
takes it from there: it asserts tag == `package.json` version (a
mismatch fails loudly and creates nothing), extracts that version's
changelog section as the release body
([.github/scripts/release-notes.sh](.github/scripts/release-notes.sh) —
a missing or empty section refuses the release), builds the package once
(`npm ci && npm run build && npm prune --omit=dev`), and attaches the
runnable tree — `bin/`, `dist/`, production `node_modules/`,
`package.json` — as `cast-X.Y.Z.tgz`. That asset is what the installer's
release channels download: the build happens once, in CI, never on an
operator's machine.
3. **Right after the release, a follow-up PR bumps `package.json` to
`X.Y.(Z+1)-dev`** (and `package-lock.json` with it) — box#90's step of
the family ritual. Installs are versioned by the tree's `package.json`
version, so a `CAST_REF=main` install between releases must land as
`versions/X.Y.(Z+1)-dev`, never as `versions/X.Y.Z` — main's tree must
not impersonate the release it merely descends from.
## Labels — who sets what
The full taxonomy lives in [LABELS.md](LABELS.md). What matters day to day is
who sets each kind — most of it is machinery, and hand-moving a
machine-owned label just gets corrected on the next pass:
| Labels | Set by |
|---|---|
| `state:*` | the labels workflow ([.github/workflows/labels.yml](.github/workflows/labels.yml)) — recomputed from GitHub's own facts every 15 minutes and on PR events. Never by hand. |
| `stale` | the same workflow — 48h without commits, comments, or reviews. `blocked` PRs are exempt: they are quiet legitimately. |
| `scope:*` on PRs | actions/labeler, from the changed paths ([.github/labeler.yml](.github/labeler.yml)). Additive — you may add more, the machine won't remove them. |
| `scope:*` on issues | you, when opening or triaging — issues have no paths to derive from. |
| `blocked`, `release` | you — automation never guesses intent. |
| `bug` / `enhancement` / `documentation` | you, on issues only — a PR's type already lives in its title. |
## Issues
Give issues the same care as PR titles: say the surface in the title, apply a
`scope:` label and a type label (`bug` / `enhancement` / `documentation`) when
you open one, and `blocked` when it waits on something — that is what keeps
the board navigable as the issue count grows.
