Blake batch owner execution

Stage active: implementation and scoped gates complete; fresh different-vendor CODE review APPROVE received. Research and plan remain the original reviewed snapshots. This execution note records later state without rewriting review inputs.

Serves Kadek foundation row 6's native ownership prerequisite; discovered-from Honeycrisp PR14. The bounded unit closes Blake batch ownership and its sole CLI caller. RTable/mine owners, chime, physical/pinning policy and phase closure remain outside this unit.

Base Erga 848e17e2522db2f6225ad72d9b1797f8735d26d0; exact Honeycrisp 9cbd48070a136e24711896c930670fcff8a147fc, Strata 494df7a0973ae10a6cc1c2022e644d70449a29d6. Approved PLAN input SHA-256 b0ab640cb3e80f337df8be5a88a8550a46d697d58bccc319922acee9df49a037; verbatim approval is retained in the audit. Eight source/test/spec/lock paths froze at 2026-10-10T05:52:03Z; no subsequent source edits.

Audit and reproducible evidence record all 21 commands, 12 exit-zero and 9 nonzero outcomes, exact source freeze, the initial corrected Clippy diagnostic, remaining provider-induced RTable failures, masked mine/chime paths, formatting comparison and intentional semver breaks. Source-file checks pass; whole-workspace and patch semver gates remain red. Named packaging and huge buildbench remain unrun. No old raw-owner runtime ran.

The CODE brief has 158 inputs and SHA-256 56fffe6e61581f09f9b534ffb957cd6afa4d560a364d57c38b205eb5880495ef. The root agent owns final acceptance, decision label, audit closure, commit, PR and merge. No release, ring, performance or physical-page claim follows from this source handoff.
