From 0b743027bae5ebfbcbcbe36789b0e6adc4bee8c7 Mon Sep 17 00:00:00 2001 From: vincent Date: Sat, 15 Aug 2026 16:19:21 -0400 Subject: [PATCH] [Vincent] #19 r2: address changes-requested review on PR #27 Rebased onto PR #12 head (47ca557). Vincent-only delta, no add/add conflict, no tracked bytecode. All seven review items fixed: 3. schema_version bumped to 2 and ENFORCED (rejects v1, rejects missing) 2. audience_choice requires the chosen form to be the SOLE survivor and every other form to be archive_ghost 5. receipts require non-empty action + exact power/scar/cost deltas; provenance is structured {source_issue:int, pull:int|commit:hex} 6. true configured signer allowlist (frozenset); human:anyone rejected 7. non-empty audience source fields; malformed containers/items return errors and never raise (fail-closed) New negative tests for every reproduced bypass. Full clean-checkout suite: 51/51 pass; __pycache__ gitignored so a clean checkout stays clean.
