WorldBisect 1.2.0

Added

• Opt-in CI companion Action retains explicitly selected successful inputs,
  finds compatible trusted baselines, reproduces both outcomes, and preserves
  the original check failure while testing candidate causes.
• Short workflow summaries and optional updatable PR comments explain the
  finding, executed tests, confidence, and next step.
• Bounded retention and input sizes, credential rejection, clean environments,
  fork isolation, and explicit non-reproducible outcomes.
• Real-tool integration checks cover Node.js, GCC and the pinned ItsDangerous
  upstream suite (297 tests), plus automatic cross-run artifact verification.
• Reviewed VERSION changes on main run the gated, attested release pipeline.

Fixed

• Native Linux AMD64 tracing keeps ptrace operations on their owning OS
  thread, scopes child waits to the isolated process group, drains command
  output, and bounds cancellation of nested processes. Commands that change
  process groups use documented portable fallback. This fixes a compiler-check
  hang and concurrent command exit-status theft.
• Release archives include the standalone installer.

Community

• Added contributor onboarding with two concrete good first issue tickets,
  public Discussions guidance, a bounded 1.x roadmap, and monthly maintenance
  notes.
• Added a consented/anonymized user-report intake form and publication gate;
  no synthetic demo is presented as real user evidence.

Security

• Future GitHub releases are published through the repository's Immutable
  Releases setting using a draft-first asset upload flow.
• Documented the moving v1 Action compatibility tag separately from full
  commit-SHA pins and archive/attestation verification for security-critical
  workflows.
