docs/RELEASE.md describes how a release is made. Nothing described how one is audited once it
exists
, so those checks were re-derived by hand each time — and the interesting ones (the artifacts
resolved from Central, run on the floor JDK) are the ones most easily skipped.

This adds docs/post-release-check.md as a file of its own rather than extending RELEASE.md or
TODO.md, so it does not collide with other work in those files. RELEASE.md gains a three-line
pointer to it; nothing else is touched.

What it is

16 checks, each stating the failure class it catches, how to run it and the pass
criterion
. The organising rule is that every item must be answerable without trusting the run that
produced the artifacts
: a green pipeline is evidence about the build, and every failure class
CLAUDE.md records as having reached a user reached them through a green pipeline.

Nothing is pinned to a version — the expected sets are derived from .github/natives.csv and the tag,
so the file stays correct for the next release. Two checks deliberately recompute instead of
reading: the patch-set hash from the tagged patches, and the publication's artifact count from the
module layout. Reading a provenance key out of a jar proves only that the jar is self-consistent.

Covered: the tag/run/commit tie-up; job outcomes (including why a skip is not benign); the
cache-free tag build; publication completeness; presence on Central; signatures from one key;
Sigstore coverage of every file; the natives jars against natives.csv; provenance consistency;
the per-artifact bytecode floors; consumer resolution from an empty local repository; real inference
on the floor JDK; the source archive's stamp and reproducible pack; the Android 16 KB and AAR
invariants; and the embedded WebUI.

Written while applying it to 6.0.0

The checklist is the deliverable; it was written by running it. Everything it checks passed on
v6.0.0 — 60 files plus 60 good signatures from one subkey, all 59 Central artifacts byte-identical
to their GitHub twins, all 120 assets attested to refs/tags/v6.0.0, 23/23 natives jars clean, the
patch-set hash recomputed from the tag matching what every jar declares, and the published jars
running real inference with CUDA offload on both JDK 21 and Java 8.

The final section records what a reader should be told rather than left to discover: the unsigned
Windows DLLs and their compensating controls, the post-release minor bump (the patch number stays
free so an emergency release off the released line can take it), and scope drift between the reactor
poms and the Gradle-built AAR poms.

Summary by CodeRabbit

  • Documentation
    • Added a post-publication checklist for auditing release artifacts, publication status, signatures, and provenance independently of the build run.
    • Expanded release checks to cover compatibility and runtime behavior, including JVM inference, Android packaging, and the embedded web interface.
    • Recorded release gaps and considerations for review, including unsigned Windows binaries and Android dependency-scope differences.

RELEASE.md describes how a release is made. Nothing described how one is
audited once it exists, so the checks were re-derived by hand every time and
the interesting ones -- the artifacts resolved from Central and run on the
floor JDK -- were the ones most easily skipped.

docs/post-release-check.md is that checklist, written so every item is
answerable without trusting the run that produced the artifacts: a green
pipeline is evidence about the build, and every failure class CLAUDE.md
records as having reached a user reached them through a green pipeline.

16 checks, each stating the failure class it catches, how to run it and the
pass criterion. Nothing is pinned to a version: the expected sets are derived
from .github/natives.csv and the tag, so the file stays correct for the next
release. Two checks deliberately recompute rather than read -- the patch-set
hash from the tagged patches, and the publication's artifact count from the
module layout -- because reading a provenance key out of a jar proves only
that the jar is self-consistent.

The last section records the standing gaps a reader should be told rather
than discover: the unsigned Windows DLLs and their compensating controls,
the post-release minor bump (the patch number stays free for an emergency
release off the released line), and scope drift between the reactor poms and
the Gradle-built AAR poms.

Walkthrough

The release documentation adds a post-publication audit checklist. It checks release artifacts, signatures, provenance, compatibility, runtime behavior, and platform outputs independently of the build run. The TODO records Android dependency-scope drift and open Windows GPU verification questions.

Changes: Published Release Audit

Layer / File(s) Summary
Release identity and publication integrity
docs/RELEASE.md, docs/post-release-check.md
The release guide points to the checklist. The checklist verifies the publishing run, GitHub and Maven Central artifacts, signatures, attestations, and native-jar provenance.
Consumer compatibility and runtime checks
docs/post-release-check.md
The checklist checks class-file versions and Central-based dependency resolution. It also runs inference with the oldest supported JDK and checks runtime output.
Archive, platform outputs, and recurring release items
docs/post-release-check.md, TODO.md
The checklist checks source archives, Android artifacts, server endpoints, and recurring release items. The TODO records Android AAR dependency-scope drift against the core POM.

Windows GPU Follow-up

Layer / File(s) Summary
Device listing and measurements
TODO.md
The TODO records that CUDA and Vulkan both list the RTX 3070. Device-selection deduplication and CUDA throughput remain unverified.

Review details

Systems and components

  • observed — docs (service) was modified; 2 changed files map to changed impact.
  • observed — TODO.md (service) was modified; 1 changed file maps to changed impact.

Before / after behavior

  • observed — Modified behavior in docs/RELEASE.md: Adds a post-publication audit step directing maintainers to post-release-check.md for checks of GitHub release artifacts, Maven Central, and a real JVM, independent of the run that built the artifacts.
  • observed — Modified behavior in docs/post-release-check.md: Adds the document’s purpose and conventions: audit published artifacts independently of the build, derive expected artifact sets from repository data at the tag, and download artifacts once into a scratch-workflow directory.
  • observed — Modified behavior in docs/post-release-check.md: Adds checks tying the tag commit to exactly one successful publishing run and main, validating that skipped jobs belong only to the other release channel, and confirming cache use is disabled both in the job environment and build-script output.
  • observed — Modified behavior in docs/post-release-check.md: Adds checks that the GitHub publication contains the repository-derived expected files plus the signed source archive, that required artifacts resolve from Central, and that every detached signature is good and uses the release key’s signing subkey.

Two entries from auditing the published 6.0.0 artifacts.

The finding: both AAR poms ship checker-qual at compile scope, which the core
deliberately keeps at provided -- its classes are major 55 with RUNTIME
retention, the UnsupportedClassVersionError that #411 put on main. Not a
blocker and not that failure on Android, since D8 consumes major 55, so it
ships in 6.0.0 unfixed. It went unnoticed because the AAR poms take only
their dependency versions from the Maven poms while the scopes are the Gradle
build's own, and because CLAUDE.md calls checker-qual one of "the core's
compile-scope deps", which it is not. Both halves need the same commit.

And measured evidence for the open device-dedup question under "Modular
natives": on the published jars the discrete GPU is registered twice, as
CUDA0 and Vulkan0, so any device_id dedup happens in selection rather than in
registration. The selection half stays open, with the reason it could not be
answered in the same run -- the load lines are below the default verbosity
threshold -- so the next attempt starts with -lv 4 instead of rediscovering
that.

Second commit (c77f03fe) records the audit's findings in TODO.md, so the checklist and what it
found this time do not live in the same file.

The finding — a new bullet under Other open verification and maintenance: both AAR poms ship
checker-qual at compile scope while the core keeps the same dependency at provided
(417 classes, all class-file major 55, @Retention(RUNTIME) — the UnsupportedClassVersionError
of #411). Not a blocker and not that failure on Android, since D8 consumes major 55, so it ships in
6.0.0 unfixed. The entry names both halves of the cause, because the second is why nobody saw it:
the AAR poms take only their dependency versions from the Maven poms (the scopes are
llama-android/build.gradle.kts's own), and CLAUDE.md's Android AAR + Kotlin façade section calls
checker-qual one of "the core's compile-scope deps" — which it is not. Gradle build and that
sentence want the same commit.

Measured evidence for an existing open question — appended to Modular natives — follow-ups
item 1, which already asks whether CUDA/Vulkan/OpenCL deduplicate the same GPU by device_id: on
the published jars the discrete GPU is registered twice, as CUDA0 and Vulkan0, so any dedup
happens in device selection rather than in registration. The selection half stays open, together
with the reason it could not be settled in the same run — the load_tensors / per-buffer lines sit
below the default verbosity threshold — so the next attempt starts at -lv 4 rather than
rediscovering that.

Nothing else in TODO.md is touched (30 added lines, no deletions): the 6.0.0-specific
After publication items stay where they are.

Make the signature pipeline fail closed.

A missing VALIDSIG produces no row, and the final awk can still return success. The documented count and per-file checks detect a missing row when followed, so this is not a silent pass under the checklist. Add an explicit per-file gpg/VALIDSIG check while retaining the fingerprint-count comparison.

Filter the run lookup by the release ref.

--limit 10 returns only the ten newest publish.yml runs, and the query does not constrain the result to $TAG. If more than ten runs occur before the audit, the publishing run for this release may be absent from the evidence for check 1. Query the tag or head ref directly, or query $RUN before applying the pass criterion.

Check the complete Central artifact set.

The loop checks only native jar URLs. It does not check native .asc files, reactor module artifacts, the standalone agent, AARs, or pom-only modules listed in the pass criterion. A release can therefore miss a non-native artifact while all commands shown here succeed. Generate the complete expected path set from check 4 and assert HTTP 200 for every artifact and signature.

Read natives.csv from $TAG.

This command reads .github/natives.csv from the current working tree. A later change to that file can change the expected classifier set and make the audit check the wrong release. Generate the rows with git show "$TAG:.github/natives.csv" or check out the tag before running the loop.

Hash the patch files from $TAG.

git ls-tree does not materialize the tagged patch files, and the next loop hashes *.patch from the current working directory. In a clean audit directory this fails; with local patch files it can hash the wrong patch set. Add an explicit git show "$TAG:$path" extraction or hash the tagged blobs directly.

Superseded by #573: both commits of this branch are cherry-picked there (authorship kept), together with the fixes for the two findings recorded here (the AAR poms' checker-qual) and an automated version of this checklist (.github/workflows/post-release.yml). Closing in favour of #573; the branch docs/post-release-check is left in place.
