Fold the writer-claim fence into the four sync write ops at their
definition sites, collapse the logical-layer fence wrappers to plain
re-exports, delete the session-accessor.sqlite middle barrel (the only
unfenced escape hatch), and retarget its 26 importers to the focused
defining modules. replaceSessionEntrySync intentionally stays unfenced:
its two production callers own their freshness guards and its return
carries no rebound signal. Net -106 production LOC, behavior-neutral.
Part 1 of the session-accessor dual-layer collapse.
* fix(ci): support frozen session-store proof
Keep current targets SQLite-strict while validating pre-cutover release targets through their persisted JSON session contract.
* style(test): format frozen session fixture
Validates forced plugin harness support for the requested provider/model before pinning Codex or any other plugin harness. This prevents an explicitly forced Codex runtime from accepting unsupported OpenAI-like providers through a hardcoded bypass while preserving implicit PI fallback and CLI runtime alias passthrough.
Regression coverage covers forced Codex rejection for unsupported openai/openai-codex support, Codex provider support declarations, CLI attempt routing, pi-embedded auth/profile forwarding fakes, Testbox scenario probes, and live Docker Codex plugin E2E.
