Real-seam coverage for each corrective fix, each checked by mutation:
requested edit/patch states (CRLF-exact, unrelated change contradicts,
partial read and underivable targets stay unverified, superseded effects are
history); directory and launch-index fsync order observed via real fsync
targets; dispatch refused when the directory fsync fails; independent
objects, threads and processes never reuse positions; settle-once and
recovery against another writer; torn-tail repair; unbound tools cannot
manufacture RUNNING/cleanup/facts or settle launches; external effects never
complete as satisfied, are always disclosed, and passing tests stay test
facts; verifier staleness and RUNNING launches without obligations;
known-scope child effects leave unrelated parent evidence fresh; browser page
refusal survives a matching approval and child authority with no claim, no
execution id and no producer call; effect-store hardlinks are caught without
scanning the store.
Replaces the uncommitted tests that asserted a CONTENT_CHANGED predicate and
blocking on any RUNNING effect.
Claims are fsynced to a per-lineage JSONL log before a caller may invoke a
backend; a persistence failure raises EffectPersistenceError (a
ResourceIdentityError) so dispatch fails closed. Outcomes and observations are
appended; nothing is rewritten. Reload validates every record strictly, ignores
only a torn final write, and fails closed on corruption, forgery or hardlink
aliasing. recover_interrupted appends INTERRUPTED/possible-impact outcomes for
claims that never settled and leaves RUNNING background effects alone.
The effect store is added to Wave 3 control-plane paths (prefix check only;
the log itself refuses aliased files), so filesystem tools cannot forge it.
Tests redirect the store to a session tmp directory.
