Summary

Item 499 — (ω-pay-births) (d) item (2) PRICED and READ, no pay landed. Docs + test + two flip specs; no library change. Cut off the merged #319 (item 498); gaps 492 / 494 / 497 are Row 19's open #313 / #316 / #318.

Rule 2 (P121, testProducersPremiseChain, 37 inputs, pinned 59 / 69 / 69 / 0 / 0): at the 59 marked content pauses every surviving mark's : v after the whole node parses (69 / 69) and every hand-off is NESTED (nv + 1 ≤ k: 69 nested / 0 at the mark / 0 below). A content character at or left of a ? mark closes it in the unwind, so h_mapTail / same-level are indicator-landing clauses, not content_dispatch_routed's (P3's "below ≥ 5" REFUTED).

Price on the #319 tree:

• scripts/flips/item499_producers_premise.json (item 471's spec re-anchored): 78 / 11, exactly item 471's bill (P1 HELD).
• 20 of its hand-offs are match h_kslot with | Or.inl … | Or.inr h => Or.inr h — the park fields' own ∨ PackAlt (item 440's three ON fields pendingBlock.h_kslot / pendingBlockContent.h_kslot / pendingContent.h_vpack) relayed into the premise; with the premise plain they STARVE unless the fields lose ∨ PackAlt too.
• scripts/flips/item499_joint_fields_premise.json (premise + the 3 fields): 101 / 17 at round 1, 140 / 19 at the fixpoint. The fields' writers are the on-drop births (closeThenBlock 9, pendingBlock 7, PBC 2 — item 498's survivor arms and five undomained elses: circular with the sites (2) was to close) and four flow-side writers in accum_flow_open_depth0 / accum_step_flow.

Source restored identical after both flips (hashes in the spec logs).

Ruling recorded in NEXT: (2a) = item 500 (premise + the producers' 20 writes + the Or.inl hand-offs); (2b) = item 501 (the three ON fields' ∨ PackAlt + the on-drop births in one fixpoint, Rule 2 first; the four flow writers are Row 12's, STOP-priced if one needs a FlowArm / GapRead change); then (3) item 494's 13.

Gates: closure-log 11..499 (gaps 18, 442, 492, 494, 497); adversarial exe 62,186 / 62,186; no pin moved.
