Deterministic replay IS the durability mechanism: every transition re-runs a
self-contained flow program (defflow source + flow/start + replay of all
recorded resume values), so the only durable state is {:flow :input :resumes}
in persist kv — restart-safe by construction (fresh space handles over the
same backend resume mid-flight runs). fork-an-agent-run = copy the record;
the two replays diverge independently. Effects are data (suspend tags +
typed request envelopes surface as plain SX); transitions ride the Phase-3
trace buffer so session history travels with the next commit. Guest numeric
results compared with = per house convention. 43/43 (196/196 total).

Per-agent buffer = persist append-only log stream + kv drain cursor;
commit-with-trace! drains everything-since-last-commit into a console-trace
object and binds it git-note style (ref notes/trace/<commit-cid> -> trace
cid). Trace never enters the commit tree; binding is a re-bindable ref layer
over immutable objects; failed commits keep the buffer; plain commit! leaves
binding to the agent. 35/35 (153/153 total).

space handle (repo + relations Datalog db); spawn! = branch-from-briefing
with a genesis spawn commit at the fork point; commit! verb snapshots a full
worktree VALUE into a typed agent-commit and CAS-advances the branch (no
shared index — multi-agent safe). Topology: fork-point via merge-base,
agents from refs, typed edges sub-agent-of/reviews/merges. Session merges
always record a two-parent session-merge commit (no-ff); conflicts commit
nothing and conclude via merge-resolve!. 53/53 (118/118 total).

Type registry (briefing / console-trace / behaviour TAG / agent-commit +
spawn/finding/refactor/test/session-merge/decision subtypes) with reflexive
transitive is-a? and create-only register-type!. Agent commits ARE git
commits (:agent-type rides as an open field, participates in the CID, DAG
machinery applies unchanged). 65/65.
