Every conversation request's non-content half (system prompt, tool schemas, call config — the EpochHeader) is now recorded in the session log: a 'request/header' full snapshot (reason 'initial' | 'resume' | 'fallback') anchors the fold at conversation birth and process boundaries, and 'request/header-delta' events (system line-trim, name-keyed tools delta, whole config) encode mid-run changes. The pure trio — foldRequestHeader / diffHeader / applyHeaderDelta — reconstructs the header any request was built under from the log alone; the writer contract round-trip-verifies every delta with a 'fallback' snapshot when the encoding cannot express a change (pure tool reordering), so a well-formed log always folds cleanly. Canonical absence: empty system and empty tools normalize to absent fields, matching request builds. Persistence and cordis catalogs regenerated; SessionEventMap paste and EpochHeader added to the core-data-structures session page.
