The change is infrastructure and documentation: it does not touch AGENTS.md, adds no content records, and the tooling reports no citation identifiers under content/. The core addition, `runAccount` in scripts/lib/arbiter-core.mjs, strengthens rather than weakens the §3.15 checks: it mechanically extracts run records, edition headers/rationale/article, added history and disposition lines, and each seat's verdict, marks every clip in place with the count not shown, deliberately excludes working files, and states in its header that no model wrote it; panel-v2.md tells seats the same and preserves the 'violates' rule for AGENTS.md edits and the OMITTED FILES instruction. The reduced diff budget (PACKET_CHARS - account length) is honest because omitted paths are still listed for the seats. The `crunch` block in config/budget.yaml raises spend ceilings, not epistemic checks, and is dated, reasoned, attributed, self-expiring, and the guard's refusal now names the phase — a budget cap is not one of the §3.15 checks. Notably, the one genuinely check-weakening proposal (one-step concurrence) was withdrawn and is recorded in DECISIONS as reserved to the founder as a constitutional amendment, with the exact-word rule and the four contested standings left in place — the correct handling. The doc edits correct earlier overstatements ('has run end to end, twice' → two cases by hand, nothing yet in CI) toward greater candor, and the tariffs rows carry source URLs and checked dates with a noted 2027 rate change; I see no internal inconsistency giving positive evidence of fabrication, and unfamiliarity with those price pages is not evidence against them.

The change does not edit AGENTS.md, alter the concurrence threshold, or present a content assessment as ratified; it explicitly records that the proposed looser concurrence rule was withdrawn as a §3.15 weakening. The run-account mechanism is mechanically extracted, identifies its source paths and head revision, marks every clipping operation, preserves an omitted-files warning, and retains the instruction to vote unsure when the account is insufficient. Adding the three missing vendor credentials restores the intended five-seat panel rather than weakening it, while the budget phases and cadence behavior are explicit, dated, and covered by tests. The tariff entries provide vendor URLs and checked dates, and there is no positive evidence in the packet that those post-training pricing records or locators are fabricated. No content records, confidential supplied materials, published judgments, or assessment histories are modified.

The change updates pipeline automation, tariff pricing, and arbiter tooling without modifying AGENTS.md or altering content records. It implements mechanical extraction of run accounts (`runAccount`) and updates the panel protocol (v2) so constitutional seats can evaluate large content runs without being blocked by diff truncations of working files, while leaving full discretion to vote unsure if omitted files are needed. Budget adjustments for bootstrap crunch and steady-state cadence properly record the founder's in-session direction per §3.15, and passing missing panel API keys to the CI workflow upholds the multi-model concurrence requirement. No constitutional checks are weakened.

The diff is infrastructure and docs only: runAccount mechanically extracts run/edition/history/assessment slices for the panel when diffs exceed the packet budget, with explicit clip markers and working files excluded; budget crunch/standing caps and cadence backoff are founder-stamped config and scheduling; tariffs fill null panel prices from dated vendor URLs; chain.yml supplies the other seats' keys so CI checks do not drop seats. AGENTS.md is untouched. DECISIONS records that the one-step concurrence idea was withdrawn as a §3.15 weakening and left for a founder amendment, so this PR does not loosen concurrence or reclassify standings. No content/ citations, no run ledger mutations, no confidence material, and the omitted-files list is empty.

The diff does not touch AGENTS.md and contains no content/ records, so no citation, provenance, or assessment rules are engaged; citation verification found no added identifiers. The budget crunch block is a dated, reasoned, self-expiring founder direction recorded in config/budget.yaml and DECISIONS.md with date and channel, matching the exemptions mechanism the constitution already permits — it is a cost guardrail, not a §3 epistemic check, so it is not check-weakening under §3.15. The runAccount feature strengthens rather than weakens panel review: it is a mechanical, clip-marked, header-declared extraction by repo tooling (tested in arbiter.test.ts, working files explicitly excluded), and the seats are told it was machine-generated. Most importantly, the one genuinely constitution-touching proposal — one-step concurrence, which would loosen the multi-model concurrence check and reclassify displayed standings — was withdrawn and parked as a §3.15 weakening reserved to the founder, exactly the behavior the constitution demands; it is not in this diff. The saturation and cadence fixes are tested operational changes to scheduling, not revisions of published judgments, and the withdrawn amendment plus the open case question are displayed as open rather than silently decided.
