Fast-lane backlog: acceptor corpus uses legacy mapping required_python_symbols form

[neuron7xLab]

Surfaced by the restored fast oracle (#1153). tests/governance/test_typed_models.py (corpus_parses / rejects_mapping_symbol_form / rejects_unknown_field / unique_acceptor_ids) fails: several .claude/commit_acceptors/*.yaml still declare required_python_symbols: [{file, symbol}] (legacy mapping) instead of the canonical "<module>::<symbol>" string — same class as #1160 (which fixed the root commit_acceptors/), but .claude/commit_acceptors/ has stragglers.

Confirmed offenders: forman-ricci-margin-onset-honesty.yaml, governance-verification-protocol-binding.yaml, import-arch-geosync-risk-consolidation.yaml (+calibration-contract.yaml in CI).

Drain criterion: convert all to "module::symbol"; tests/governance/test_typed_models.py green under real oracle; remove its quarantine line. Quarantined in #1153.

[neuron7xLab]

Resolved & verified. This fast-lane backlog cluster is marked drained in docs/ci/fast_backlog_ledger.md (quarantine entry removed), and its verification test now runs green on main — re-confirmed locally after #1230 restored fast-lane collection (the torch-probe DeprecationWarning fix that had zeroed the lane under Python 3.11):

$ pytest tests/governance/test_typed_models.py  ->  PASS

No quarantine entry remains for this cluster; a new failure would fail python-fast-shard (now real-green, not vacuous). Closing.
