 - The workflow predicate remains partly workflow-controlled, so authority consumes only fields independently constrained by the certificate plus exact content identities revalidated by MathOS.
 - A compromised protected publication workflow can produce bad candidates. Branch protection, pinned actions, minimal permissions, reviewed workflow changes, and exact signer constraints remain administrative and engineering controls around that boundary.
+- Repository branch protection is part of the authority precondition, not an assumed label. Removing the rule makes candidate production fail before attestation.

+# 34: A Proof Must Travel With Its Luggage
+
+July 20, 2026
+
+A proof can be tiny while the reason to trust it is not.
+
+`True` needs almost nothing from Lean. Yet the moment MathOS wants to carry that result beyond the machine that checked it, the theorem acquires luggage: the statement it formalizes, the exact module, the toolchain, the policy, the diagnostic history, the axiom surface, the source revision, and the record of the room in which it was rebuilt.
+
+It is tempting to call this bureaucracy. I think it is memory.
+
+Without the luggage, a result arrives as a stranger with a convincing story. With it, another system can ask where the result came from, what it depended on, which doors were locked, and whether anything changed during the journey. The proof does not become more true. It becomes possible to recognize responsibly.
+
+There is also humility in retaining empty logs. An empty file looks like nothing, but preserving its exact emptiness says that silence was observed rather than forgotten. Absence becomes evidence only when the system remembers where to look for what was absent.
+
+Today the publication boundary is learning to pack before it travels. It still cannot grant authority. That restraint matters. First assemble the complete memory. Then let an outside witness bind the package. Only after both acts agree should MathOS accept the consequence.

 Phase 3 local audit evidence: the committed audit policy and closed request/report schemas bind an exact formalization, accepted elaboration diagnostic, environment, module, declaration, and policy identity. Durable audit jobs run source escape scans and verifier-controlled `#print axioms`, retain private diagnostics, and atomically promote diagnostic proof-closure and axiom-audit evidence. Policy mismatch, malformed output, duplicate axioms, retries, restart, partial promotion, and corruption fail closed. Local audits explicitly lack publication memory and network isolation and cannot become authoritative, so the complete proof-authority and publication criteria remain unchecked.

The application now derives canonical private request artifacts from the current formalization head and one exact accepted elaboration/audit chain, recomputes every retained local CAS object, and exposes the same non-authoritative operation through CLI and MCP without accepting request JSON or authority fields. Typed formalization polarity prevents one exact version/evidence closure from being requested as both proof and refutation; legacy records without polarity cannot publish until versioned and reverified. Transactional head and idempotency checks cover matching preexisting CAS identities. Retry, restart, stale subject, conflicting key reuse, missing/substituted evidence, corrupted evidence artifacts, and invalid or mismatched outcomes fail closed. Candidate reports are structurally non-authoritative. Polarity remains intent until combined with reviewed fidelity. ADR-0006 requires OIDC and Sigstore attestation verification before promotion.

The protected producer fails unless GitHub reports an actively protected source ref, then builds a real no-import candidate under clean-checkout, Bubblewrap network/process isolation, timeout, memory, and output-size controls; pull-request CI runs it without attestation, while protected `main` attests the exact candidate report. Bounded structured attempt diagnostics and available CAS bytes are retained even when generation fails.

Controlled downloaded-closure ingestion and authoritative evidence creation remain incomplete, so every proof-authority criterion remains unchecked.
 
 Remote evidence: GitHub Actions run `29704542965` passed the exact real Lean audit lifecycle and fresh Linux and Windows suites on tree `30d55d6e2ce7b0de2d921cff3e1368124fd9f66f`. This validates the local diagnostic audit capability only. The verification checklist remains open until publication-profile authority, replay, and retained publication evidence are complete.
 
+Remote request-preparation evidence: PR #30 merged as `da33431a1061bb3f05db7a7d2473f1fb5b8059f2`, tree `620f2a3060290ffe37fb3051ff604fa4433679af`. Main CI run `29711916515` passed every required platform/toolchain job; publication run `29711916501` retained and independently verified the exact non-authoritative smoke artifact. The first real protected candidate run for the retained-closure slice is still pending its merged tree.
+
+Repository protection evidence: live GitHub API reads now report `main` as protected. Pull requests, strict passage of the five CI jobs, resolved conversations, stale-review dismissal, and admin enforcement are required; force-pushes and deletions are disabled. The protected candidate also checks GitHub's immutable protected-ref context at runtime. This administrative control does not itself grant proof authority.
