 - Current-head review found an AgentMail collection scope leak and agent-keyed Arcade discovery ownership. Both new actual-auth regressions were red before the fixes. Email accounts now pass the shared resource evaluator before metadata or credential discovery; aggregator settings, credentials, inventory, and sync leases use the responsible user, while audit and secret-access records preserve the actual agent. The Arcade fixture initially created a draft and omitted provider authorization metadata; it was corrected to represent an active provider account. Its guarded HTTP transport also required an explicit deterministic fixture; a prior real transport attempt returned 401. No provider authentication was weakened.
 - A reused test database retained a Slack bot identity and caused a 409 during the full suite. In a fresh PostgreSQL database, all **70 API/OpenAPI tests passed**, including 43 assembled-server cases and binding the human-only secret response to its committed nonsecret generation. Server typecheck passed. Earlier fixture and contract-update failures remain accounted for here.
 - Failed GitHub secret replacements retain the prior copy only after its committed generation is confirmed unchanged. A changed or unreadable generation blocks copying and reconnecting; an explicit status check can restore the earlier copy when the server confirms it. All three new replacement cases were red before the fix; all **82 GitHub UI tests passed** afterward. Cloud enrollment map entries now name instance-admin creation/callback checks and distinguish the HTML/303 browser return. Maps and UI token gates passed. Fresh successor CI and reviews remain required before merging.

+- Master advanced to `c7c12dbc79` while the review fixes were being qualified. Its published Copilot v62 identity is preserved byte-for-byte. The combined delegated connection guidance uses v63 with digest `sha256:f29dc04c3217ad74aeaf96b2c466d5a1dc6c55942f5bd4db9c1cf52f2985d19e`; the shared identity generator and **60 Copilot installation tests passed**. The first root-level invocation selected no Runner tests; the package configuration ran the intended suite. Migration 0379 is unchanged by this merge.
