Two version-source shapes failed CLOSED in a way that silently disabled
/ship's queue-collision check:
1. A --version-path / .gstack/version-path target that is a package.json
was read as raw text: the whitespace strip turned the JSON into
'{"name":"frontend",... which parseVersion rejected, so every read —
local, `git show`, and rival PRs' claims through the GitHub/GitLab
Contents APIs — fell back to 0.0.0.0 and competing claims were dropped
as "malformed".
2. parseVersion required exactly four components, so gstack-next-version
exited 2 on EVERY invocation in a 3-digit repo. That CLI IS the
queue-collision check; /ship then took its documented offline path of
naive local arithmetic, two branches cut from the same base picked the
same version, and git merged the duplicate without a conflict.
New lib/version-source.ts holds the shared semantics so both CLIs agree
by construction: parseVersion accepts 3- or 4-digit (3 pads the micro
slot for uniform comparison), versionWidth/fmtVersion keep a 3-digit repo
3-digit through bumping and formatting, micro coerces to patch on 3-digit
repos (with a warning in the output), and extractVersion reads a .json
version-path as JSON (.version) from any byte source. gstack-version-bump
treats a package.json version-path as that repo's single source of truth
(written in place, DRIFT_* states can't arise — no second file to drift
from). Detection is by shape, not new configuration.
Scope per the wave plan's version-tooling end-state spec (decision 11,
ENG-OV1): this is the READING capability + 3-digit acceptance ONLY.
gstack's own VERSION file stays the 4-digit source of truth; nothing here
flips authority to package.json. The PR's bundled fix for the
.gstack/version-path pin being ignored by classify's base read lands
separately (#2462) — these tests drive the JSON version-path through the
explicit --version-path flag.
Re-derived from PR #2501 by @YiftahR (73 tests pass across
test/gstack-version-bump.test.ts, test/gstack-next-version.test.ts,
test/ship-version-sync.test.ts).
Fixes#2501
