From the full-repo Codex audit:
- The publisher read discovery fields one per line, so a report title
with newlines shifted every later field and published a manifest
without source.publish_date, which every client rejects (blocking all
syncs). Read them NUL-separated, and refuse to write a manifest missing
a field clients require.
- The snapshot builder copied the SQLite file with cp; committed data
still in the -wal file of an open database would be missing. Checkpoint
first (a no-op for the publisher's closed database, so the bytes and
hash are unchanged) and refuse to copy when that cannot complete.
- install.sh took the tag from a greedy match, which on a compact
single-line releases response picks the last tag, not the newest (it
installed v0.2.3 over v0.2.4 in the new test). Split fields first.
- scripts/audit-msn-fundamentals.sh read the symbol map from a path that
no longer exists and silently checked no stocks.
- release.yml granted contents: write to every job; only publish gets it
now. Actions in the release and snapshot workflows are pinned to commit
SHAs.

- install.sh: POSIX sh installer that detects OS/arch (incl. Rosetta),
resolves the newest vX.Y.Z release via the GitHub API (skipping
ownership-snapshot-current), verifies SHA256SUMS, sanity-runs the
binary, and installs atomically into ~/.local/bin without sudo.
Supports --version/--dir and IDX_* env overrides; prints a PATH
hint, a NixOS flake suggestion, and helper-tool install hints
instead of calling package managers.
- scripts/install-sh-test.sh: fixture tests against a local fake
release server (latest, pinned, piped, checksum mismatch, missing
release, unsupported OS, PATH hint, reinstall).
- ci.yml: install-script job (ShellCheck, sh + dash on Linux, sh on
macOS).
- release.yml: attach install.sh to each release.
- README + docs/INSTALL.md.
