Summary

Decision

Status: KEEP LIVE / NO-GO.

The compact route recorded routed=0 and fallback=1. Issue #454 remains open. This PR changes no production parser code.

Validation

  • Passed the focused PHP Docker guard twice.
  • Used one CPU, 4 GiB, GOMAXPROCS=1, and GOFLAGS=-p=1.
  • Confirmed no out-of-memory kill and no wall timeout.
  • Passed formatting, prose, diff, and scoped Canopy checks.

- Pin source, grammar, and C-oracle artifacts with SHA-256 checks.
- Run the compact admission route on the edited witness.
- Assert one fallback occurs due to recovery. Verify tree parity.
- Record the guard receipt in the blocker document.
- Update CHANGELOG to track the pinned state and keep issue #454 open.
