v0.0.1-rc12

Orbit v0.0.1-rc12

Prerelease candidate built from main after PR #99, PR #100, PR #101, PR #102, and PR #104.

Included since rc11

• CLI startup runtime banner and /status panel.
• Smoke/benchmark harness for repeatable runtime validation.
• More reliable --mtp-required smoke harness behavior.
• Persistent MTP reset before completion to avoid stale request boundary reuse.
• MTP timeout/cancel cleanup so interrupted long completions do not poison the session.
• Smoke harness wall-clock per-step timeout and bounded /cancel cleanup.

Validation

• Full unittest discover PASS.
• compileall PASS.
• git diff --check PASS.
• CLI smoke PASS.
• Smoke harness serial scenarios PASS.
• MTP strict gate PASS with simple_chat --mtp-required.
• MTP timeout/cancel recovery PASS.

Notes

• The smoke harness is diagnostic infrastructure, not a runtime optimization.
• On CPU-only systems, prefer single scenarios or small scenario groups with explicit timeout.
• pwd_followup, shell_error, and shell20 are not used as primary strict MTP proof because they can run through route/final paths where MTP is not used by design.
• Dual shell evidence optimization remains paused as correctness-sensitive.
• Final/retry cache anchor experiments remain paused.
