Add faithful single-choice chat results, tool stream activity, error-frame retries, and isolated protocol caching.
Reject empty cached completions with the same value predicate as transport, add regression coverage, and adopt Apache-2.0.
_minimal_fields and the pre_135 acceptance dicts missed the two new
columns, KeyErroring against migrated 39-column physical tables
(caught by the pre-merge integration gate; production path is
signature-gated and unaffected). Verifier gaps P2-1/P2-2 closed:
full suite 1764 passed, PG 30 passed, lint green.
B1 chunk = any delta (content or reasoning), B2 telemetry plumbing
via explicit _emit pass, B3 orchestration entry gate for independent
stall hedging; N1-N9 advisory fixes merged. Human decisions recorded
in design section 9.
Records what the two Codex review rounds found, which findings held up
under verification, and how each was resolved -- including the one that
changed docs rather than code. Also lists the evidence behind the
completion claim: suite counts, coverage, the 19-minute real-wait Redis
run, and the import contract.
