 **Post-release republishing and attestation, restored:** the separate repositories' own per-package pipelines also republished each package under one or more alternate npm names (and, for several packages, under a `@exadev/<name>` scope to GitHub Packages), and signed an SPDX SBOM plus a build-provenance attestation against every release tarball. The orchestrator itself has no equivalent step, so three post-release jobs in the same CI workflow now provide it (previously [#732](https://github.com/ExaDev/documents.js/issues/732)): when the release job finishes, it diffs the `name@version` tags the orchestrator created and fans out over exactly the packages that released, each leg checking out its package's own release tag so a queued next release can never shift the tree under it. One matrix republishes each package that `.github/release-republish.json` maps to GitHub Packages (`npm pkg set` of the scoped name and a `publishConfig.registry` override at publish time — never a second package.json, so the mirror cannot drift from the real metadata); one matrix republishes under each alternate npm name the same map lists (`document-bytes`, `mrkdwn.js`, `pdf-codec.js`/`pdf-parser.js`, the five `document-schema.js` aliases, `js.documents`, `doculi`) via OIDC trusted publishing; one generates an SPDX SBOM (`pnpm sbom --sbom-format spdx --prod`), packs the shipped tarball, attests SBOM and build provenance against it with `actions/attest`, and attaches the raw SBOM to the package's GitHub Release. Nothing depends on these jobs, so a failure there can never block the release or the Pages deploy, and every leg skips as already-done on re-runs.
 
-**SEA binaries:** a fourth post-release matrix builds a Node [single-executable application](https://nodejs.org/api/single-executable-applications.html) binary for `document-cli`, `document-mcp`, and `document-rest` — the three packages whose own `tsdown.config.ts` produces a fully-bundled, dependency-free entry point for it (see each package's own README for what the resulting binary covers) — for Linux (x64), Windows (x64), and macOS on both Apple Silicon and Intel, and attaches each one to that release's GitHub Release assets under a name qualified by both OS and architecture (`document-cli-macos-arm64`, `document-cli-macos-x64`, and so on), since two of the four build legs are both macOS and would otherwise collide on upload. Node's own `--build-sea` (Node 25.5.0+) copies whichever `node` binary builds it, so the job installs a second, newer Node (beyond the workspace's own pinned version) immediately before that step, specifically to get the native ESM `mainFormat` support `document-cli`'s Ink-driven bundle needs; `.github/scripts/build-sea-binary.ts` holds the platform-specific ad-hoc `codesign` signing step macOS needs (Linux and Windows ship unsigned). Like the three jobs above, nothing depends on it and a failure there can never block the release.

Every non-standard-architecture leg (`macos-26-intel`, `ubuntu-24.04-arm`, `windows-11-arm`) is still a standard GitHub-hosted runner, not a paid "larger runner".

 If a release job is itself cancelled by its own timeout after the per-package publish work has already completed but before it collects the released tags into those four matrices, a plain re-run cannot recover it: the collection step diffs tags against a before/after snapshot taken within that same run, so a later run sees every already-existing tag as pre-existing, not new. `ci.yml`'s `workflow_dispatch` trigger takes an optional `backfill_tags` input (comma- or newline-separated `name@version` tags) for exactly this case: a `collect-backfill-matrix` job builds the identical four matrices directly from the given tags, without re-running the release itself, and the four post-release jobs consume whichever of it or the normal release job produced output. Trigger it with `gh workflow run ci.yml --field backfill_tags="pkg-a@1.2.3,pkg-b@4.5.6"`.

 Both names install the exact same package and the exact same binary — `package.json`'s `bin` field declares both `document-cli` and `doculi` pointing at the one built entry point unconditionally, so there is no "real" name and an alias; pick whichever you find easier to type. Unlike a sibling's second _npm package name_ (`documents.js`'s own `js.documents` — see that package's README, and note the older per-repo pipeline's GitHub Packages republish this pattern used to mirror is no longer running, per [ExaDev/documents.js#732](https://github.com/ExaDev/documents.js/issues/732)), this is one package with two `bin` entries: a second name for the same build, not a second build, and unaffected by that gap.
