Hosted copy opened under Q83 (qssx2n), extended by Manager to PRs whose only blocker is rust-tests signing capacity (decision e9841ddd). The head is the exact reviewed head of #5063 (independent security GO 6631052246). Security fix for the Codex P1 on #4979 (fabric R1, 0d027f6). Priority: must merge before the next release cut.

U04 exposure check: PASS at b4dbcc9995fc7628dda72fc9e0a0ab46e813769e.

• Diff: the hosted copy of fix(fleet): preserve Fabric re-key metadata only from authenticated own claims #5063 at its exact GO head, based on main: 1 commit on merge base 81d36837, signed and reported verified by GitHub. 2 files, +80/-4: crates/smallclaims/src/store/fabric_rekey.rs and release-notes/fabric-rekey-authenticated-own-metadata.json. No .github/ or apps/fractal-web/private/** path changes. LICENSE is unchanged (3f80bc4c). The branch merges with current main (ed4fe828) without conflicts. The exposure scan finds no hits.
• Source: Fabric re-key preservation now reads the local member's mode and endpoints from the membership fold, so the existing writer, signature and incarnation-window checks apply. It no longer uses the latest fleet.member-endpoints claim for the local host, which an admitted peer could write. The new test replicates a peer-written forgery for the local host, both before and after a legitimate prepare, and checks that the forgery is neither preserved nor republished. Test keys are generated at runtime and node IDs are synthetic. A full-diff review found no exposed credential, private host, personal path or private reference. The release note describes the fixed behaviour only, at the level of detail the public fix already shows.
• Prior U04: no earlier U04 comment exists on fix(fleet): preserve Fabric re-key metadata only from authenticated own claims #5063, so this is a full check, not a carried verdict.
• GO: the independent security GO at this exact head.
• CI: PASS. Workspace CI run 41833099037 completed with success; required jobs linux-gate, genie-freshness, typescript-client, fractal-web, ci-script-tests succeeded. Public repository check also succeeded.

This check covers exposure and source safety at this head only. It does not authorize a merge.

Signed: Janitor (agent/dotfiles/janitor).
