Summary

  • Review 63588 / D4 follow-up tried to return Cause D zero_arm_match_still_refuses_holds and both Cause R data-record claims to the ordinary floor after Carry the grammar digest and production index on the prepared grammar; share the parse-witness fixture trees warm #11032.
  • Required-floor job 103370532596 on run 34631915615 BUDGET-REFUSED them at 508ms / 512ms / 517ms (then later MemoryStallRefusedPageThrash on the terminal ledger, infra, not a subject verdict).
  • They are back on floor_cost_debt_censored_chunk_04. Restoration remains fill-netted tokenize/parse/normalize under 500ms. Cause F's sniff stays off this chunk.

They were enrolled on floor_cost_debt censored_chunk_04 after D4's floor-of-record interrupt (review 63588). With the grammar digest on the prepared grammar, small-module tokenize/parse/normalize is fill-netted under the 500ms line, so withholding them hid the repair.

…USED them.

Required-floor job 103370532596 on run 34631915615 refused the three identities at 508/512/517ms. #11032 did not put this tokenize/parse/normalize shape under the 500ms line; withholding again is the censored-class fact, not a failed restore to hide.

Receipt (required-floor job 103370532596, run 34631915615, head f983be3)

After #11032, Cause D/R discriminators still BUDGET-REFUSED on the floor of record:

identity cpu
v2.test.claim.body_lowering.data_initializer_fn_value.data_record_arrow_lambda_field_is_not_retained_holds 508ms
v2.test.claim.body_lowering.data_initializer_fn_value.data_record_fn_literal_field_is_not_retained_holds 512ms
v2.test.claim.body_lowering.single_arm_match.zero_arm_match_still_refuses_holds 517ms

Same ~500ms fixed per-claim front end (tokenize/parse/normalize rebuilt per claim frame). Raising the ceiling is refused; a self-budgeted lane is refused; reducing the shared fixed cost is the only lever, and that is a capability (adhoc-a2708dd9-252), not a roster edit.

review 63950: its prescribed fix for a second interrupt is re-enrolment. That is already main's state (floor_cost_debt_censored_chunk_04). This PR is comment-only against main on the roster and will not land.

Closing without merge: comment-only vs main is not a landing. Rows stay censored on chunk_04 as main has them. Successor: dashboard work item adhoc-a2708dd9-252.
