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.
