# Changelog

History before 0.1.0 lives in git — cast has said `0.1.0` in `package.json`
since its first commit, but grew its release surface (this file,
`cast --version`, tagged releases with a prebuilt asset) on the way to
actually cutting it, and this file starts there.

## Unreleased

### Fixed

- **The release ceremony re-arms the changelog, and CI notices when it
  doesn't** (#113) — stamping `## Unreleased` into `## X.Y.Z — DATE` is
  done by hand in the ceremony PR; no workflow writes this file, and
  nothing put the heading back. So `main` sat with the shipped section on
  top and no `## Unreleased` above it — this repo's state from 0.1.0
  until this entry. A PR authored before a release and merged after has
  its entry land under whatever heading now occupies that position: the
  release that already shipped. Git does that *cleanly*. The stamped
  heading and the incoming entry never overlap textually, so the one
  signal an author trusts — "git told me to look" — is missing exactly
  when the result is wrong. rig watched it happen (heavy-duty/rig#66, the
  origin of this fix): an entry landed inside published `## 0.1.0` an
  hour after 0.1.0 shipped, and was caught only because someone was
  reading. The published release body is never at risk — `release.yml`
  extracts notes from the tree at the tag, before anything late can merge
  — which is also why nobody notices: the file that drifts is the one
  only maintainers read. Three moves. `## Unreleased` is back above
  `## 0.1.0` (this entry re-creating it *is* the repair). CONTRIBUTING's
  ceremony step now re-arms in the same diff that stamps. And
  `test/release.test.ts` keys the rule to `package.json`: a stamped top
  section is legal while the version is bare — the ceremony's own tree,
  and main until the `-dev` bump — but once the version says `-dev`, the
  top section must be `## Unreleased`. That is the distinction #108 had
  to collapse to make the ceremony shippable at all, recovered rather
  than reverted: the ceremony stays green at every step, and a disarmed
  dev `main` goes red. box and rig carry the same fix
  (heavy-duty/box#108, heavy-duty/rig#66).

## 0.1.0 — 2026-07-19

### Fixed

- **The release suite accepts the ceremony's own tree** (#108) —
  `test/release.test.ts` demanded the real `CHANGELOG.md`'s literal
  `Unreleased` section extract non-empty and contain `#96`: false by
  construction on the `release: X.Y.Z` tree the ceremony's own PR produces
  (it stamps that heading into `## X.Y.Z — date`), so the first real
  release PR turned CI red and the flow blocked itself — invisible to the
  fork rehearsals, which tag a branch (`release.yml` runs; `ci.yml` never
  does). The guard now asserts its actual purpose: whatever the TOP `## `
  section is — `Unreleased` between releases, the stamped version on and
  right after one — the exact `release-notes.sh` the workflow runs
  extracts it non-empty. rig's twin is heavy-duty/rig#44.

- **`apply` no longer demands a GitHub App for a manifest that declares no
  applications** (#103) — found live in the 2026-07-19 release drill, where a
  databases-only manifest (`applications: {}`) rendered its plan of two
  creates and then died in preflight on `no GitHub App bound`, over a binding
  nothing in the run would ever have used: a GitHub App exists to clone
  application source, cast reads it in exactly one call (the application
  create), and databases and services never touch it. That unconditional
  resolution gated infra-only projects — the databases a fleet's other
  projects share — behind the GitHub-App browser-registration ceremony for no
  reason. `apply` now resolves the App only when the desired state actually
  contains an application; a manifest that does declare one still refuses on
  a missing binding exactly as before, clean plan or not, because that
  binding is state the next create will need.
- **A manifest with no `${…}` refs applies without a store** (#104) — the
  greenfield manifest-first bootstrap was a chicken-and-egg with no exit,
  found by the 2026-07-19 release drill against two fresh Coolify 4.1.2
  instances: a registered project whose manifest declared databases only
  (zero `${…}` refs) could not take its first `apply` — apply refused with
  `no secret store for <org>/<repo> in <env>`, and `capture`, the documented
  way to get a store, rightly refuses a project that is absent on the box,
  because apply is the verb that would create it. The drill unblocked with a
  hand-rolled empty store (`printf '' | age -r … -o secrets/….env.age`),
  documented nowhere. Now `diff`/`apply` gate that refusal on the manifest
  actually *referencing* a secret, asked via the same parser resolution
  uses: when the templates resolve zero `${…}` refs, an absent store is
  treated as empty and the run proceeds, printing a loud one-line note
  naming the path the store would live at — and since there is nothing to
  decrypt, the age key is not demanded either. The moment any template
  gains a `${…}` ref, the refusal returns byte-identical to before.
  `capture` and `destroy` are untouched.
- **`CAST_AGE_KEY_FILE_<ENV>` is now settable for every environment name**
  (#102) — `<ENV>` was the name uppercased verbatim, so env `drill-b`
  advertised `CAST_AGE_KEY_FILE_DRILL-B`: a variable no POSIX shell can
  export, which walled off the injected-key channel (and its
  process-substitution trick) for every hyphenated environment. Found live
  in the 2026-07-19 release drill. Characters outside `[A-Z0-9]` now map to
  `_` — env `drill-b` reads `CAST_AGE_KEY_FILE_DRILL_B` — and the refusal
  advertises the mapped name. The standing-key path keeps the exact
  environment name, so two names that collide on the variable still resolve
  their own keys on disk.

### Added

- **Merging a release-labeled PR is the release — and the release re-arms
  main itself** (#111; box#96's design) — `release.yml` now also fires on
  pushes to main (not `pull_request` events: fork-sourced ceremony PRs get
  a read-only token there — the round-1 catch). A decide step reads the
  version transition from the push (`event.before` → the pushed head) and
  answers four states: release-flow *work* merged under the `release`
  label — `-dev` endstates, and the post-release window — no-ops green
  with a NOTICE; the two genuinely ambiguous bare states refuse loudly;
  a true transition then requires a merged, `release`-labeled PR behind
  the commit (read via the API — the label is the operator's declared
  intent) before the door opens. It then tags the merge commit, builds
  the `cast-X.Y.Z.tgz` asset once, publishes — and bumps main to
  `X.Y.(Z+1)-dev` itself, direct push with a loud open-a-PR fallback, so
  no follow-up bump PR exists on the paved road. The tag-push path stays
  as the documented fallback and backfill, and both paths run the same
  steps so they cannot drift. First-release edge: 0.1.0 never carried
  `-dev`, so its ceremony (#110) ships by manual tag; the automation
  applies from 0.1.1 on.

- **Tagged releases with a prebuilt dist asset, and an installer that
  installs them** (#96) — the cast half of the flow designed in
  heavy-duty/box#83, plus the piece unique to cast: a **prebuilt asset**,
  because cast is the one repo where the source tarball is *not* the
  package. A release is a PR, then a tag: the `release: X.Y.Z` PR bumps
  `package.json` (and `package-lock.json`) and stamps this file's Unreleased
  section with version + date; the merge commit is tagged bare `X.Y.Z`
  (box's tag scheme — no `v` prefix). `release.yml` turns the tag into the
  GitHub release — after asserting tag == `package.json` version (a
  mismatch fails loudly and creates nothing) — with that version's section
  of this file as the body, extracted by the same
  `.github/scripts/release-notes.sh` the test harness drives, and with the
  runnable tree attached as `cast-X.Y.Z.tgz`: `bin/`, compiled `dist/`,
  production `node_modules/`, `package.json`, built once in CI
  (`npm ci && npm run build && npm prune --omit=dev`). `install.sh` now
  defaults to the **latest release**: the tag is resolved by following the
  `releases/latest` redirect and reading the `Location` header — no API, no
  token — and the download is that release's asset, so **no `npm ci`, no
  `tsc`, no devDependencies ever run on the operator's machine**. `CAST_REF`
  picks the other two channels: a tag pins a release (its asset first,
  source as the fallback for a ref that has none — `refs/tags` outranks a
  same-named branch), a branch (`CAST_REF=main`) tracks the development
  tree and is the one channel that still builds from source, the only place
  `npm` is required. Until 0.1.0 is cut the default channel has nothing to
  resolve and dies saying exactly that, naming `CAST_REF=main` as the way
  to install today — it never falls back to main silently, because "I
  installed the latest release" must not quietly mean "I installed whatever
  main was that second". The channel only decides *which* tree arrives and
  whether it is built here — whatever it fetched lands in the versioned
  layout (`versions/<package.json version>`, `current` flipped atomically)
  like any other install.
