GitHub reruns preserve the failed workflow SHA, so a repaired convergence control cannot resolve an already committed release. A missed workflow_run event can also leave mutable aliases stranded without another attempt.

Three defects that the v6.4.3-rc.1 cut exposed, each with its contract note
and proof:
1. scripts/release-preflight-worker.sh published the smoke stack on host port
7655 and probed it directly. pulse-dev also hosts the maintainer's dogfood
Pulse instance on 127.0.0.1:7655 and a second instance on 17655, so the
release smoke failed to start after every other stage had passed on the
qualified head. The worker now honours PULSE_RELEASE_PREFLIGHT_E2E_PORT,
otherwise takes the first candidate host port pair it verifies free and
fails fast when none is, probes health and update status on that port, and
hands Playwright the same base URL.
2. .github/workflows/publish-helm-chart.yml resolved the chart version before
checking out the repository, but de41ea1883 made that step call
scripts/write_github_output.py, so every chart publish since failed with
"can't open file". Run 33580123246 hit it after all other staging passed;
the checkout now precedes the resolver.
3. docs/release-control/control_plane.json maps the 6.4.3 version prefix to
release/v6.4. Run 33579042375, dispatched from main, failed inside the
compiler dispatch because main advanced one minute after the pipeline
pinned its source SHA; with pull requests landing every few minutes a
candidate cannot hold its SHA between prepare and compile. release/v6.4
was created from main at the exact-SHA-qualified commit 56e51e622e and
carries these same fixes; v6.4.3-rc.1 published from it.
The deployment-installability contract records the worker port and toolchain
rules and the Helm checkout order; release_preflight_test.py and
build_release_assets_test.go pin them.
The disposable host reached multi-user.target in a degraded state because distro Podman housekeeping used overlay storage inside the outer container. Mask unused units, force VFS for explicit daemons, and fail closed on systemd unit failures so retained rootful evidence remains trustworthy.
The pre-batch upstream rootful source-closure manifest was created before the local Unix recovery test. Include that compiled installer input so merged qualification evidence remains bound to the complete harness.

(cherry picked from commit f5ad4e343e)
A workflow dispatch by branch can resolve after that branch moves, allowing an unreviewed tip to enter the release pipeline. Require every publishing dispatch to name its expected source SHA and make the workflow reject a different source or workflow commit before checkout.

Stable promotions built whatever the dispatch branch was at that second.
The resolver checked that HEAD descends from the promoted release
candidate but never that its content matches, so v6.4.0 shipped 64
changed files, including product code, that v6.4.0-rc.12 had not
soaked. Every v6 version was mapped to main, which now moves every few
minutes under the autonomous maintainer, so each fix to a candidate
brought everything landed since and stable was never an exact soaked
commit. Five of six stable minor releases shipped under version-bound
owner exceptions that waived the soak.
From v6.5.0 the release train applies (RELEASE_PROMOTION_POLICY.md,
"Release Train"): a two-week train sized to measured velocity, a
release/v6.N branch per train declared in the control plane so the
workflow refuses a dispatch from anywhere else, a stable promotion that
may differ from its candidate only in release metadata unless
hotfix_exception names active customer harm, and a seven day soak for
minor releases. The 6.4.x line stays on main so the v6.4.3-rc.1
candidate already prepared there is unaffected. The gap is registered
as coverage gap release-train-exact-candidate-promotion.
Open the v6.4.3 candidate line from main. The v6.4.2 tag was staged on
2026-08-31 but never activated: its release run was cancelled after the
private Pro build failed the compiler memory gate, so the latest published
stable is still v6.4.1. This candidate carries the complete v6.4.2 change
set plus the corrections landed since that tag, including the stale PBS
Backup Running state (#1815), the Windows Unified Agent auto-update 404
(#1820), and shared-token same-hostname agent identity collapse (#1753).
Packet: VERSION, compose and install-docker defaults, Helm chart metadata,
release notes with a declined visual plan, changelog, pointer docs and
the shipped docs mirror, and the deployment-installability cutoff note.
Rollback target is v6.4.1 and the mobile decision is no-mobile-impact.
Tests: the packet tests now describe the 6.4.3 train, v6.4.2 is recorded
as an unpublished stable so it is never derived as the previous stable or
rollback target, and the Python v6.4.2 notes expectation matches the
phrase the notes actually use.
