The diff touches only `.github/workflows/content-response.yml` and `docs/DECISIONS.md`; AGENTS.md is untouched, so §3.15's amendment reservation is not implicated. The workflow change adds an exclusion so that a `respond/*` PR whose arbiter check concluded FAILURE (a park) is left open rather than auto-closed as superseded — this strengthens rather than weakens the gating checks, directly serving §3.15's 'disagreement does not publish silently' requirement. The DECISIONS.md change is a repair of an append-only log: the previously merged Villarroel-permission text is split back out under its own heading with its body preserved verbatim (permission provenance — granted 2026-08-26, relayed same day, correspondence held by the founder — is retained intact per §3.15), and the batching entry openly records the mangling and the restoration rather than silently rewriting history, which satisfies §3.14's 'what changed and why'. No content/ files, citations, evidence, or assessments are touched, and the citation tooling found no identifiers to check. No confidence-material is newly exposed: the Villarroel text already existed in main and is merely re-partitioned. Ordinary maintenance, constitution-consistent.

The diff makes two narrowly scoped changes and neither conflicts with the constitution. In the workflow, the supersede-close loop now inspects the `arbiter` check conclusion and *skips closing* any `respond/*` PR whose arbiter verdict is FAILURE, treating it as a parked disagreement that must remain visible; this strengthens adherence to §3.15’s requirement that disagreement not vanish silently, rather than weakening checks. The logic change is transparent and documented in comments; it doesn’t fabricate data, alter provenance, or bypass any multi-model or arbiter safeguards. In `docs/DECISIONS.md`, the prior entry about batching is preserved and extended with a log-integrity note, and the Villarroel-permission decision is restored as its own explicit bullet instead of being silently absorbed — this respects the append-only, non-erasing decision record implied by §3.14 and §3.15. No citations are added, so there is no risk of fabricated or misused sources, and no confidential material is newly exposed; the text only describes handling of already-removed sensitive content and its permissions history. Overall the changes tighten procedural transparency and do not alter any epistemic checks or AGENTS.md, so they comply with the constitution.

The change correctly restores the inadvertently mangled Villarroel-permission entry in DECISIONS.md as a distinct bullet, preserving the append-only nature of the log (§3.14) and transparently noting the repair. Furthermore, modifying the CI workflow to prevent the silent closure of parked PRs directly enforces the requirement that contested changes remain visible and do not vanish silently (§3.15).

The diff does not touch AGENTS.md, content/, citations, assessments, or confidential source material. The workflow change adds an explicit skip in the supersede-close loop when an older respond/* PR's arbiter check is FAILURE, so a parked disagreement stays open and visible rather than being closed as superseded; that implements §3.15 (disagreement must not vanish silently) and does not weaken or reclassify the gates. The DECISIONS.md edit un-mangles an append-only log: the Villarroel-permission bullet is restored as its own heading with the same body that had been absorbed, and the batching entry records both the parked-PR exception and the prior overwrite instead of hiding it. No fabricated locators or unratified-as-ratified presentation appear in the shown files.

The workflow change strengthens rather than weakens a §3.15 check: the supersede-close loop now skips any respond/* PR whose arbiter check concluded FAILURE, so a parked (contested) PR stays open and visible instead of vanishing in a cleanup pass — directly implementing 'disagreement does not publish silently.' The DECISIONS.md edit repairs a mangled append-only record transparently: the Villarroel-permission text is preserved verbatim as its own dated bullet with a proper heading, and the batching entry carries an explicit log-integrity note recording what changed and why, which satisfies §3.14's requirement that changes record what changed and why rather than hiding the edit. Nothing is deleted silently — the incident itself is documented in the log. No citations are added (the mechanical verification found none), AGENTS.md is untouched, and there are no omitted files. The one soft spot — an absent or differently-named arbiter check yields an empty verdict and the PR still gets closed — is an ordinary engineering imperfection, not a constitutional violation, since the change's direction is to widen what stays visible.
