This is an infrastructure subtraction: it deletes retired workflows, scripts, library modules, tests, the /proposals page and one doc, and updates the runbook and decisions log. Nothing under content/ is touched (the tooling found no citation identifiers in added content lines), no assessment overlay or provenance stamp is rewritten, and AGENTS.md is untouched, so §3.15's reserved-amendment rule is not engaged. The §3.15 checks themselves survive intact: `PR risk check` and `Arbiter` workflows are unmodified, the five-seat panel and parking rules are only re-described in docs/MAINTENANCE.md to match the founder amendment already in the base constitution, and `harvest-governance` is moved into the chain sitting rather than dropped (so /panel keeps displaying verdicts, i.e. disagreement stays visible). Every retirement names its replacement verb or honestly says there is none (Bench, study freeze, art generator) in docs/AUTOMATION.md's "Subtraction record", and the decisions entry stamps the direction's date and channel — I cannot verify the founder's "begin" from outside the repo, but per temporal humility unfamiliarity is not evidence of fabrication and the record is stamped as §3.15's operating-record clause allows. One thing I would want answered on the record, short of parking: with the Operator workflow retired, §3.15 still requires that a lone seat's review note be "answered on the record" and that contested cases be reconciled — the PR asserts the edition verb's reconsideration and manual/founder handling cover both, but no code in this diff demonstrates the review-note answering path now exists.

The change edits no AGENTS.md and adds no content citations, claims, evidence, or assessment records requiring epistemic verification. It retires redundant workflows while retaining the consequential publication gates: PR risk classification, the Arbiter, loader-derived stale-check detection, and build-time study-hash verification remain in place. Deleting `preflight-citations.mjs` is not check-weakening because its own removed documentation says it was only a local preview and that the Arbiter performs the actual citation verification. Historical proposal and disposition artifacts remain in git, while `docs/DECISIONS.md` records the subtraction with a date, channel, quoted founder direction, and explicit identification of retirements lacking replacements.

This PR retires superseded legacy workflows, scripts, tests, and documentation from the Maintain era as part of the transition to the unified verb chain, pursuant to recorded founder direction. None of the constitutional checks under §3.15 (the PR risk classifier, the multi-model Arbiter, mechanical CI) are removed or weakened; AGENTS.md is untouched. No content files under content/ are added or modified, and the operational changes are clearly documented and traceable in docs/DECISIONS.md and docs/AUTOMATION.md.

The diff retires superseded Maintain-era workflows, scripts, tests, the /proposals page, and EXTRACTION_PIPELINE.md; it does not edit AGENTS.md. No content/ ledger citations, quotes, or provenance stamps are added (citation verification is empty), and nothing confidential is published. docs/DECISIONS.md and the Subtraction record name the founder direction with date and channel (“in session: begin”), map each retirement to its replacement verb or state none, and keep Arbiter, PR risk check, CI, and harvest-governance (now a Chain sitting step). next.ts preferring a non-empty inbox and chain.yml harvesting verdicts preserve the gates rather than weaken §3.15.

This is a deletion/move refactor of automation, not a content change: no AGENTS.md edit appears anywhere in the diff, and the citation-verification section confirms no new citation identifiers were added. The subtraction record in docs/AUTOMATION.md and the DECISIONS.md entry are internally consistent with the change stat — every named retired script, workflow, library module, and test file is in fact deleted here, replacements are named (or absence of replacement is honestly declared, e.g. the Bench, freeze, and art generator), and the founder direction is stamped with date and channel ('in session') as §3.15's amendment requires. The load-bearing checks are preserved rather than weakened: the citation check survives in the kept `citation-check`/`verify` path, the risk classifier, arbiter quorum (≥4 complies, zero violates), fail-closed CI, and the review-note/parking semantics documented in MAINTENANCE.md match the §3.15 amendment already in the constitution rather than loosening it; malformed panel replies recorded as `unsure` with the defect named is more honest than silent quarantine, and still cannot reach the ≥4-complies pass. The reconciliation and harvest duties move into the sitting (`edition` reconsideration, chain harvest step) rather than vanishing. I note as review material, not violation: the disappearance of the Operator's parked-PR-answering and article-gap duties leaves 'revise, or the founder decides' as the answer path for two-seat parks, which the operator should confirm is intentional; and the claim of 272 passing tests is the PR author's own assertion, verifiable in CI.
