Git records no diff entry for a directory itself, so adding
.changes/foo/bar.md only surfaced the nested path, which the single-level
trigger regex skipped. The entry validation and the renderer were both
bypassed, letting a nested directory reach main and break every later
fragment render with 'unexpected directory'.
Trigger the top-level tree validation on any .changes change outside
.changes/released/ (which keeps its own immutability and release-seal
checks), and assert .changes itself is still a tree so replacing it with a
blob or symlink cannot empty the child listing unnoticed.
Re-rendering stays keyed on fragment changes so a README-only edit does
not fail on an empty fragment set.
The fragment gate only ran validation when the changed path matched the
legal fragment name pattern, so `.changes/Foo.md`, `.changes/notes.txt`
and a symlinked fragment slipped through untouched and then broke the
next PR that added a legal fragment. The trigger now fires on any
top-level `.changes/` change other than README.md and rejects every
entry that is not README.md, released/, or a 100644 blob named
^[a-z0-9][a-z0-9._-]*\.md$.
The renderer had the same hole from the other side: `find -type f`
is false for symlinks, so a symlinked fragment was silently dropped
from the rendered notes, and the `[a-z0-9]*.md` glob only constrained
the first character so `chat reply.md` passed. It now walks every
top-level entry and fails on symlinks, unexpected directories,
non-regular files and illegal names. Both scripts pin LC_ALL=C so the
ASCII ranges cannot match uppercase under a different collation.
Adds regression coverage for illegal names, non-markdown entries,
symlinks and executable modes on both the gate and the renderer.
Stable releases previously required a byte-identical tree with the
promoted beta (only CHANGELOG.md could differ) and local releases had
to run exactly at the origin/main tip with an atomic main+tag push.
Together these froze main for the whole beta-to-stable window.
Relax both gates while keeping the beta soak mandatory:
- stable still requires an explicit delivered, non-withdrawn beta whose
commit is an ancestor of the sealed release commit; the tree-identity
drift check is removed
- local releases accept any clean sealed commit contained in
origin/main history (any branch or detached HEAD) and push only the
release tag; command-compatibility checks compare the sealed HEAD,
matching CI
ossutil 2.x signs requests with V4 and refuses to run without an
explicit region, so the OSS mirror sync would fail in CI even with
valid credentials. Derive OSS_REGION from the endpoint host
(including -internal variants) and fail fast when it cannot be
derived.
