process_audit_verdict now calls validate_signer_separation
before any state save or ledger write (previously the function
had no production caller on this path: it only ran inside
collect_failed_checks via decide_pushback, which itself has no
production caller). Signer is bound to the authenticated
caller -- a body signer differing from the caller is rejected
-- and executor/coordinator_approver/qa_tester must be
declared and distinct from the caller; missing field,
self-audit, or forged signer raises ValueError, mapped by
_loop_run to HTTP 400 with no side effects. No new route.
Honest limits are in the helper docstring: declared-identity
enforcement only (task rows store no authoritative executor /
coordinator / QA identity; task executor is a backend, not a
person), and audit-fix reaudit verdicts are out of scope
(the fix poster is not necessarily the re-auditor, so binding
signer to the fix poster would be a mis-binding).
(cherry picked from commit 56dce5165f4d08f38fe1730b9eea3b78f90cb97d)
Reconcile-port: handler_lifecycle.py docstring hunk redirected into cloud/server.py audit-verdict handler (target keeps 6-mixin split; enforcement itself is in audit_loop_wiring.py and applied cleanly).
Server-side execution for the track-1 pure driver (#260), no driver
semantics changed: audit verdict / fix completion / correction /
rebuild confirmation endpoints persist LoopState in audit_loop_state,
write every step through the #241/#247 ledger path (ledger first,
state second, fail-closed), derive fix/rebuild subtasks, and block
merge/release via the existing #247 chain reader. POST
/tasks/{id}/release follows the #259 contract (global-admin write,
fresh hard-gate evidence, merged status, multi-source 409 with no
audit write on block); deploy.py stays outside task gates.
