producer-code-r3 — the AX42 producer code for rehearsal 3a
About SN116 Carbon
Cut from main a0c111f on the owner's direct authorization, 2026-10-08, after the Test Lead confirmed the gate. Gate contents: #808 DESIGN-REPORTS-BATTERY-01: battery Q3 v8 diversity and power reports, with per-quantity control severities carrying each limit's registered unit (neutral control schema v2). #812 score_tuning: -c safe.directory=<root> on the registry's two git reads, so the producer can read the root-owned /opt/carbon checkout as its own service account. #818 intake: the door's commitment fact states the deployment's real mode; a door built without _serve says "unstated" rather than claiming "not_checked". #823 signer: opt-in --request answer-key, bound to a named --receiver; the default signer signs only the miner session's /carbon/v1/mcp. Server authority is unchanged — an answer-key fetch is still refused 403 answer_key_no_validator_permit without an on-chain validator permit. #825 producer: an owner-only refusal names the operator's own path. Battery implementation: 2.0 (implementation_versions.CURRENT). The 3.0 change (#826) is deliberately NOT in this cut, so rehearsal 3a stays on 2.0 throughout; it merges immediately after. Level 2, 3 and 4 development code: present on main, not loaded by the producer. Verified at this exact commit by static import-time reachability from the producer entry points — challenge_validator.producer, challenge_validator.startup_shard, battery_bank, battery_quiz and battery.intake. 17 modules load at import time; no level2, level3 or level4 module is among them, and none appears behind a deferred function-body import. The level attack adapters (battery_level2 and battery_level3 from BUILTIN table, by importlib on a name computed from (challenge_id, level), and the producer entry points contain no reference to the attack registry, so that table is never consulted on this path. Non-vacuity of that check: the same scan run from carbon.battery.level2 reports carbon.battery.level2, level2_specmuon and level2_worker, so the ne
