Why

Company Email still retrieves its durable credentials from the former application location. Its active configuration and recovery checks should use the company infrastructure location together.

What

Move Email's credential references and recovery checks together while preserving existing values and history, and prevent cache regeneration from seeding production during recovery.

The prerequisite copy and independent readback in #5518 are complete. Deployed consumer and recovery acceptance remain required after this change.

Part of #5387

Walkthrough

The change moves the admin, maintainer, and agent credentials to canonical infrastructure/email/ paths in secret resources and Vault policy. Production overlays disable their PushSecret seeding. Recovery tooling adds canonical mode aliases and a 24-hour snapshot window with up to five minutes of clock skew. The workflow, sandbox, tests, and recovery documentation cover canonical and legacy custody layouts.

At 26bb051bddbd93401c30448f3483ee5160958f1d, CI 40751224405 passed. I read the actual Linux recovery job: pinned OpenBao restored both credential layouts and refused corrupt snapshots, altered records, incorrect recovery keys and the wrong credential layout. The current-head native canonical test passed; this is isolated recovery evidence, not a production migration receipt. Affected race tests, lint, shell checks and schema validation of the changed manifests also passed.

The current-head Codex receipt is clean. Review objects, conversation comments, threads and check runs contain no outstanding findings.

This remains a draft until #5518 has verified the actual production copy and a fresh readback confirms all three destinations still match. After this change merges, the canonical production restore and live consumer readback must pass before its part of #5387 is complete.

restored-cluster recovery. Preserve automatic seeding for genuinely fresh

At 01bee6e3007966e5427bce37c2bf6a702a408f66, CI 40782376559 passed. The actual Linux independent-manifest job restored both supported three-record credential layouts with pinned OpenBao and refused corrupt snapshots, altered records, incorrect unseal material and the wrong layout. The production/fresh-install regression verifies that ordinary production recovery cannot seed missing retained records from regenerated caches; explicit fresh initialization remains available. Affected race tests and schema checks passed.

The CodeRabbit recent-review verdict names this exact head and reports no actionable comments. Its authenticated summary passes the reviewed verdict classifier. All four review surfaces are complete, with zero unresolved threads and no outstanding findings; native mergeability is CLEAN. The earlier restore finding is addressed and resolved.

The actual copy and readback prerequisite is complete in #5518. After the protected merge, verify the canonical consumers and run the canonical independent recovery workflow before completing this portion of #5387. This revision does not activate storage encryption or OIDC.

The reviewed head remains 01bee6e3007966e5427bce37c2bf6a702a408f66, with passing validation and the current-head clean review. Its tree also merges cleanly with freshly fetched main. I am holding it outside the queue while the active protected production deployment completes, then will rebind readiness and enter it with the expected head pinned.
