### Prepublication provenance and qualification order

This order clarifies the cutover above and governs subsequent worker contracts.
It specifies work to implement and verify; it is not evidence of release readiness.
Distinguish frozen-input provenance from release qualification:

1. Freeze both native products at the final accepted integration commit. A
separate protected job may attest the exact prepared inputs and a fixed
provenance-only record before execution. This grants no platform acceptance,
publication permission, or channel eligibility. Preparation stays read-only;
its candidate/projection/pair byte contracts remain unchanged.
2. Authenticate those inputs and package custody before prepublication execution.
A reviewed production launcher may accept an explicit checksum-bound local
asset source for this purpose. It must verify the selected product, target,
source, outer asset and extracted binary through the normal checked cache
path. Expected digests come from authenticated input provenance in the verified
package binding, never from a caller-supplied asset-and-digest pair. Reject
malformed inputs without fallback, and never execute the supplied
file directly. This capability must be implemented and reviewed first;

Define the trusted digest source for local assets.

The launcher contract must require the expected digest to come from authenticated provenance. Reject asset-and-digest pairs supplied only by the caller before checked-cache execution.

ordinary null-qualified preparation remains non-executable.
3. Pack the final npm tarballs once with the authenticated input binding. Keep
final qualification and execution receipts outside those immutable bytes:
frozen inputs -> input provenance -> tarballs -> stage receipt -> execution
receipts -> release qualification -> distribution readbacks -> channels.

Make all npm publishers consume the recorded tarball.

agentplugins-npm-publish.yml transfers a staged tarball, but does not verify the downloaded bytes against tarball_integrity or tarball_shasum. npm-publish.yml and npm-runtime-publish.yml still publish from checkout directories. The runtime workflow also publishes a different tarball from the one used for its smoke test. Make each publisher download and verify the recorded tarball, then pass that file to npm publish. Do not publish from a checkout directory.

1311 - 1314, Update all npm publisher workflows—agentplugins-npm-publish.yml,
npm-publish.yml, and npm-runtime-publish.yml—to download the recorded staged
tarball, verify it against both tarball_integrity and tarball_shasum, and pass
that exact verified file to npm publish. Ensure the runtime publisher uses the
same tarball artifact as its smoke test and never publishes from a checkout
directory.

Do not embed a future qualification digest in a tarball whose execution
receipt must itself be included in that qualification.
4. Require all twelve native product/target lanes and authenticated public-packed
acceptance before qualification signing or native release publication. Public
acceptance includes actual installed launchers, declared host/Node support,
genuine production installer dry-run and lifecycle, preservation/parity, and
the complementary ten-project/thirty-plan gate. Help or injected planner
success cannot replace distributed installer success. Missing lanes remain
unresolved; they never become skipped successes.
5. After qualification and both native release readbacks, install those identical
npm tarballs from authenticated staging artifacts into fresh disposable homes,
checking their recorded digests without packaging from a checkout. Before
publishing either npm package, run their production launchers without the local
asset source and verify anonymous native downloads from the canonical public
GitHub release URLs. This is not a prepublication npm-registry download. Both
publishers verify the staged tarball SHA256, SRI and SHA1 and publish that exact
file without repacking. Require both registry provenance/readbacks before pair
channel promotion. Preserve the repository-wide latest release policy needed
by historical kit launchers; a non-default release is still a public effect.

Every admitted receipt binds the exact source and signer workflow revision,
completed run/attempt, artifact identity/digest, subjects and evidence closure.
Extract the same checked archive bytes. Provenance signatures authenticate input
custody, not future test results. Cryptographic verifier compatibility requires
real positive and negative evidence, not supplied fixture JSON.

No synthetic transport, manufactured cache/assessment qualification, test trust
flag, command/network-policy relaxation or provider-control workaround satisfies
these gates. Required process observation and genuine installer services remain
execution prerequisites. Preserve existing private/v1 contracts and the explicit
limitations of offline fixture evidence. Native, npm, PyPI, Homebrew and final
clean-clone gates remain required; this clarification neither reduces scope nor
opens phases 7-11 before the stable MVP release.

PyPI remains a launcher/distribution surface, not a second Python
implementation of the authoring engine. A source distribution must not contain
a divergent authoring path.
