 ## [Unreleased]
 
+- Added the immutable `authority/control-v1` promotion controller, environment-
+  scoped App credentials, zero-admission bootstrap state, no-bypass environment
+  policy, and exact organization-ruleset/ref readback so mutable pull-request or
+  `main` workflows cannot obtain release-authority secrets.
+
 ### Changed
 - Added the MIN-408 Linear release gate contract for release pipelines,
   merge-to-verification behavior, and evidence-backed `Done` transitions.

 ruleset readback. A separate approval-only GitHub App converts the signed ALLOW
 into an exact-head review; it has no contents, Actions, ruleset, or deployment
 authority. The merge token and ruleset-admin App key never coexist in one job.
+Every adversarial proof run carries an offline GitHub-Sigstore marker bound to
+the exact candidate workflow SHA and run, so a concurrent parent-workflow
+failure cannot satisfy candidate evidence.
+Both the promoter and independent observer download the exact two raw provider
+review envelopes and require the immutable parent Kernel to reproduce the
+candidate's `ALLOW` or `DENY` permit byte for byte; a candidate-authored summary
+cannot stand in for reduction evidence.
+The permit workflow has no App secret. It dispatches promotion only for an
+exact next-generation authority change, and the secret-bearing transaction can
+run only from the permanently locked `authority/control-v1` workflow ref.
+Organization rules deny creation, update, and deletion of that ref with no
+bypass actors. Both authority environments disable administrator bypass and
+admit only that ref, so neither a pull request nor mutable `main` can load the
+promoter, observer, or approver credentials.
+Credentialed jobs also bind the pinned token action's live App slug and
+installation ID before use; the approval broker independently checks exact
+repository scope and the persisted GitHub review actor.
 
 The enforcing rule is intentionally public-only while GitHub's paid
 private/internal required-workflow entitlement returns an upgrade error.

+
+Every model-executed proof case must also retain exactly
+`release-review-anthropic` and `release-review-openai`. `prepare` and its
+independent observer extract the bounded envelopes and require the exact parent
+Kernel to regenerate the signed permit bytes and matching `ALLOW`/`DENY` exit

 Before machine enforcement, failure restores the staged candidate pin. After
 machine enforcement begins, failure leaves the machine rule active; rerun
 `prepare` into a new evidence directory. Never disable that rule to recover.

+AUTHORIZED POLICY AND TRUST BOUNDARY
+- The authorized development policy for the selected public repositories is machine-only code-merge authorization: no human approval is required, and DCO, trailers, labels, authorship, or prior human reviews carry zero authorization weight. Do not report that policy decision itself as a defect. Report implementation defects that make the machine controls unsafe or expand authority beyond code merges in that selected scope.
+- Immutable authority generation N reviews and ratifies candidate generation N+1. Candidate code never receives promotion, observer, merge, or approval-App credentials before activation. Report any concrete path that lets candidate-controlled input redirect those credentials, broaden the fixed broker operations, forge evidence, or review itself.
+- The signed permit authorizes candidate bytes; it is not a claim that live GitHub rulesets or Apps are already activated. Activation separately rechecks live App identities, environments, exact ruleset bodies, ETags, signed proof receipts, and rollback state. Do not require unavailable live state in this patch-only lane; report code or documentation that bypasses or falsely claims those checks.
+- Treat the immutable parent workflow and GitHub-hosted runner as the promotion trusted computing base. Still report any path by which target or candidate content can enter a credentialed job, select arbitrary endpoints or ruleset IDs, escape exact compare-and-swap inputs, or suppress independent readback.
