vstack 0.49.0

vstack 0.49.0

Organizational behavior, practiced on AI agents. vstack is a curated library
of 34 diagnostic patterns drawn from organizational behavior, social psychology,
and group dynamics — each rewritten for the domain of AI agents rather than
human teams.

What changed in this release

The CI ratchet — gate only on new findings — plus a vdiff correctness fix.

Added

• vstack-diagnose --baseline <report.json> — compare the current run
  against a saved diagnose report and, with --fail-on, gate only on
  findings that are new relative to the baseline. This is the standard
  ratchet: a gate won't fail on pre-existing, already-accepted findings, and
  it tightens as you re-baseline. Prints a vs baseline: N new, M pre-existing summary to stderr.

Fixed

• vstack.vdiff.diff_reports crashed on real reports. It assumed
  per_pattern was a name-keyed dict, but actual DiagnoseReports (and
  their JSON) carry per_pattern as a list. diff_reports (and therefore
  the vstack-vdiff CLI) raised TypeError on genuine vstack-diagnose
  output; it now normalizes both shapes. Regression test added.

Changed

• _gate_exit_code now takes a list of severities (so the gate can score
  either all findings or only the new ones).

Compatibility

• All tests pass. --baseline is opt-in; no breaking changes.
