…p open PRs per author at 20 (Closes #10067) Two rules as a t27 card, with the 2026-10-17 queue measurements as test data: 1. Batching: a port wave PR (title `spec(port)`, branch `zcode-port-*` or `port/cr-chat-*`) lands one PR per ring or crate. Each spec still earns 27 TRI in the Queen earnings ledger, so no author loses credit. A 20-file wave is 960 Actions runs as 20 PRs and 48 as one. 2. Budget: at most 20 open non-draft PRs per author; the excess is held as a draft and promoted as slots free. Lab (Railway, t27c at 063da04, zig 0.16.0): test-report 11/11 pass, 0 vacuous, 3 invariants proved; parse-complete 8/8 in specs/policy. Negative control: OPEN_CAP 21 / CHECKS_PER_PR 28 fails to compile. Spec only; wiring it into a gate is a follow-up. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

specs/policy/pr_budget.t27, a t27 card holding two rules for the PR queue:spec(port), branchzcode-port-*orport/cr-chat-*) lands one PR per ring or crate, not one per file. Each ported spec still earns 27 TRI in the Queen earnings ledger, so batching keeps every author's credit. A 20-file wave as 20 PRs costs 20 x 29 checks + 20 merges x 19 push runs = 960 Actions runs. As one batch it costs 48. That arithmetic is a test.OPEN_CAP). The excess is held as a draft and promoted as slots free. Every author counts the same, the owner's account and the Queen's bees included.The 2026-10-17 measurements are test data: open PRs (dmitrii-f-t27 128, gHashTag 162 with 131
queen-*), a rate of 6-9 PRs/hour, 732 master push runs and 76 dmitrii-f-t27 PR runs out of 1000, and 29 of 51 queued runs at 18:00Z.This is the spec only. Nothing reads it yet, and no existing PR is touched. Wiring it into a gate is a follow-up.
