Rulings L1-Q4 (revised) and L1-Q9 (A).
Library (elaboration.rs):
- The sequential per-jurisdiction loop and step(jurisdiction) are deleted.
ElaborationOutcome loses Clean and Inactive, which nothing produces now.
- sweep(permits) takes one snapshot and returns Ok unless the world is
Active. It reads the store's in-flight listing once, builds the claim set,
and spawns one step_session per entry into a JoinSet. Each session holds a
permit from the caller's pool for its whole step.
- Every spawned session finishes before sweep returns. A quarantine-class
error is returned after that, and no session starts after one has returned
such an error. The sequential loop's early return also started no further
session. Any other error is logged at debug.
- demand_entries is the claim set. For each swept jurisdiction it takes
every covered boundary in derivation order, then the deficit if nonzero.
Each entry is matched against the listing by world, jurisdiction and
answer before anything is drawn. A match adopts the row's session and
command id; if several match, the oldest is adopted and the rest are
logged as orphans. An unmatched entry derives its id and draws its lens
(fresh_session). An answer is claimed once, and so is a command id.
- step_session(command_id, session, snapshot) is the old step body. Its
lookup and Cut 3's adoption rule are unchanged.
- step_in(jurisdiction), test-only, steps the first entry of one
jurisdiction's claim set, so the Cut 3 tests keep reading one session's
outcome.
Store: the listing now returns only ElaboratorInFlight rows. A committed
session ends in ReadyToSubmit, so listing that stage adopted a committed
deficit row, and every later sweep resubmitted it (AlreadyApplied) instead
of opening the next deficit session. That departs from the map's listing
contract.
Dungeon: elaborate_world and the ignored road test pass
state.elaboration_permits to sweep. The driver doc states that sweeps never
overlap.
Tests: 12 library tests.
- Concurrency: distinct_entries_run_at_once_under_the_ceiling,
the_sweep_never_exceeds_its_ceiling, a_sweep_holds_a_permit_while_it_infers,
one_answer_is_one_session_per_sweep.
- Claim set: a_boundary_under_nested_roots_is_claimed_once,
a_deficit_entry_is_one_per_jurisdiction_per_ancestry.
- Errors: a_retryable_fault_ends_only_its_own_session,
a_quarantine_error_is_returned_after_every_session_finishes.
- Rediscovery: a_stranded_deficit_session_is_adopted_with_its_refusal_intact,
a_boundary_session_is_repaired_after_a_commit_and_a_tick,
the_store_gains_no_orphan_per_commit, a_row_for_another_answer_is_not_adopted.
Dungeon adds saturating_one_pool_never_delays_the_other. The dead-end
fixture can now declare its commons (or commons and a ward) as a
jurisdiction root, with a subject that holds a goal, because a sweep visits
only jurisdictions that have a deficit row. The Cut 3 tests call step_in.
Docs: ghostlight-world-ontology.md states the concurrent sweep as the
shipped rule.
Counts: library 456 + 1 ignored, Dungeon 53 + 1 ignored. This commit
builds.
