* Move the turn message ordinals and the turn-row revision to the neutral timeline folder Pure moves so a shared timeline assembler can use them: Codex's message ordinal counter becomes ProviderTurnMessageOrdinals and Claude's turn-row revision becomes the provider-neutral agent-journal turn-row revision. Only names and import paths change. * Admit one provider event's writes as one transition, and let rows be found again after a restart - A sink transition is admitted whole or not at all; its steps run back to back at their turn in the journal's write queue, and each resolver reads the fold with every earlier write landed. A resolver may also say where the row belongs (turn scope, provider reference), and the writer always hears how the transition landed. A resolved lifecycle batch chooses its settlement mutations from the fold at execution. - New optional row field providerItemRef: the provider's own reference for the item a row is, written only where the row's identity cannot spell it (Codex keys messages by their place in the turn and renumbers its item ids on resume). Set by the creating write, kept by revisions, indexed by the journal fold, never read by clients. A downgrade test shows an older host and client render such rows unchanged. - Provider timeline identity schemes (shared legacy arm, Codex) and the join index that resolves a provider item to its row from memory or the fold: ordinals and request incarnations are read back from the rows, so a restart or an evicted entry finds the original row instead of placing a new one. * Recover message ordinals from the journal's highest place, and forget joins read from a replaced epoch A fresh join index continued a turn's messages at the first free place, so a journal holding only a later ordinal (an imported or removed earlier row) had its sequence back-filled. The place is now one past the highest ordinal any row or echoed send holds there, read through a pure scheme reader. The join caches also drop what they read when the journal's epoch is replaced. * Spell the subagent thread's message slot without spreading an identity union * Keep the journal store under its line limit after the main merge * Drop the provider item reference, join index and identity schemes from the transition PR Nothing in production reaches the state they defended (an assembler that lost its memory while its child keeps streaming the same turn), and the stored Codex id was positional. The legacy identity scheme moves to the assembler PR with its first caller; the Codex scheme and any persisted reference wait for Codex to move onto the assembler. The Codex ordinal counter goes back to codex/, since no neutral code imports it. * Write a resolved settlement in one transaction through enqueueRows A settlement too large for one row now commits all its rows or none, through the journal's existing all-or-nothing write, instead of a row-by-row writer. Every row is built before any commits, so a settlement naming one item twice is refused before anything is written. * Drop the transition's landing report; keep the turn-row write fire-and-forget Nothing reads which steps of a transition wrote. A failed step fails the sink, leaving the steps before it written; the header says so, and tests cover it plus a settlement whose second row fails inside the transaction. writeAgentJournalTurnRow returns nothing again, as on main. * Run a transition's steps as a prefix; drop the paced flag and resolved options A failed step no longer lets the steps after it write: each step checks, at its own turn in the journal's queue, whether the write handed over just ahead of it completed, using the queue's count of completed write bodies (a promise would report the failure only after the next step ran). The sink fails only once every step has had its turn. The item step's `paced` size bypass and the resolver's replacement `options` are removed; nothing planned uses them. * Run a transition's steps in one queued write that loops over them The steps of one event now share one turn in the journal's write queue: a loop writes each in its own transaction through the row writer's synchronous writeRows (split out of enqueueRows) and stops at the first throw. Prefix semantics and "nothing lands between the steps" now hold by construction, so the completed-write counter on the queue, the step gate and the allSettled barrier are gone; the queue is back to main's bytes. * Use current provider handles in transition tests
