Conversation
nvca and the three subprojects under deploy/stacks declared version_file plus dev_prerelease, so a push to main only bumped a -dev.N prerelease read from a VERSION file, and a stable version appeared only on a release branch cut by `github-release branch-cut`. Every other subproject in the repo takes its version from semantic-release on merge to main. Two release models in one tree is the cost this removes. Drop version_file and dev_prerelease from the four entries, delete the VERSION files, and remove the branch-cut command along with its two workflow jobs and the release-**/v* push trigger. Release automation now runs on the default branch only; a patch on a release-* maintenance branch is tagged by hand. The other workflows keep their release-** triggers, so existing trains still build and test. initial_version alone could not carry these version lines across. The floor is only synthesized when a service has no tags at all, and each of the four had hundreds of -dev.N tags. Their stable tags were also unreachable from main: the nvca 3.2 line lives on its release branch and two of the stacks had no stable tag. Left alone, semantic-release would have restarted each line at 0.1.0. The floors are registered as initial_version and anchored on the commit graph at cutover: nvca 3.3.0, nvcf-compute-plane-stack 0.2.0, nvcf-self-managed-stack 0.8.0, nvcf-observability-stack 0.0.0.

- Around line 443-446: Update the “Creating tags” guidance in AGENTS.md to
prohibit manual tag creation only for releases from main, while explicitly
allowing or requiring maintainers to create and push patch tags for
maintenance-branch releases, consistent with RELEASE.md.
In `@tools/ci/github-release`:
- Around line 874-877: Update should_process_auto_service so automatic releases
are permitted only when branch equals default_branch; an empty or detached
branch must be rejected. Add a regression test covering the empty-branch case
and confirming semantic-release is not invoked.

The subtree guide said "Creating tags: do not", but RELEASE.md requires a maintainer to create and push the patch tag by hand on a release-* branch, since automation runs on main only. A maintainer reading only the subtree guide would skip a required maintenance release.

Why
nvcaand the three subprojects underdeploy/stacks/declaredversion_fileplusdev_prerelease, so a push tomainonly bumped a-dev.Nprerelease read from aVERSIONfile. A stable version appeared only when a commit landed on a release branch cut bygithub-release branch-cut. Every other subproject in this repo takes its version from semantic-release on merge tomain.Two release models in one tree means a contributor has to know which applies to the subproject they touched, and every release doc has to describe both. This removes the second one.
What changed
github-release-subprojects.json: droppedversion_fileanddev_prereleasefrom the four entries; addedinitial_versionfloors taken from theVERSIONfiles.src/compute-plane-services/nvca/VERSIONand the threedeploy/stacks/*/VERSIONfiles. Verified unread outside the release script: no Bazel rule, Makefile, helmfile, stack render script, or chart template references them.tools/ci/github-release: removed the version-file and dev-prerelease publishers,branch_cutand its helpers, and thebranch-cutsubparser (16 functions, all dead once those paths go).should_process_auto_servicenow returns default-branch-only..github/workflows/release-tags.yml: removed both branch-cut jobs, theoperationdispatch input, and therelease-**/v*push trigger.bazel.yml,build-test.yml,secret-scan.yml,license-dependencies.yml, andactionlint.ymlkeep theirrelease-**triggers, so existing trains still build and test.RELEASE.md(largely built around the dev-prerelease model),docs/dev/github-release-process.md,docs/dev/release-process.md, andsrc/compute-plane-services/nvca/AGENTS.md, which told agents togit tag v1.20.0in the retired standalone-repo format.Version continuity
initial_versionalone does not carry these lines across.synthesize_initial_version_anchorreturns early whenever any tag exists, and each of the four has hundreds of-dev.Ntags. Their stable tags are also unreachable frommain: the nvca 3.2 line lives onrelease-src/compute-plane-services/nvca/v3.2, andnvcf-compute-planeandobservabilityhave no stable tag at all. Left alone, semantic-release restarts each line at0.1.0.Each line is anchored at cutover instead, at the version its

Plan Summary
Not applicable.
Usage
Cutover, once this merges and while the dry-run gate is still on:
Repeat for the three stacks at their floors. The first release for each is then the next bump above its anchor, for example
3.3.1for an nvcafixor3.4.0for afeat.Testing
python3 tools/ci/test-github-release.py— 40 tests pass. Removed 8 obsolete cases covering branch-cut and the version-file publishers; added coverage that no service declares the retired fields, that the four floors are registered, and that noVERSIONfile can reappear under those paths.Dry-ran
github-release anchorfor all four services against the real tag graph and confirmed each resolves to the expected tag on a distinct, note-free commit.QA not needed; no runtime code changes.
Notes
tag_exists_for_versionintools/ci/github-releaseis dead, but it was dead before this change too, so removing it is left out of scope to keep the diff focused.Release branch naming is unchanged and still reported by the
tagcommand; what changes is that automation no longer cuts or tags those branches.References
