 ## Typed account selection is checked inside the database mutation lock

+**8D.11:** Apply the same conditional target identity contract to authorized-key add/delete/clear, sharing canonical CLI validation/commit paths. Expose fingerprint metadata only through a zero-wait snapshot; never return stored key blobs. Treat key indices as stable, potentially sparse slots, not response-array positions. Listing uses protected JSON POST to reuse bounded target admission, not a new query parser. Public-key import is bounded to 384 decoded text bytes within the existing 768-byte body, with canonical blob/curve validation on the existing dispatcher. Target revocation/self uncertainty and browser-shell restrictions are unchanged. See `docs/phase8d11_implementation.md`.

 **Current 8D.10 slice 2:** Extend conditional identity checks to password replacement; create uses canonical duplicate/capacity/commit policy. Keep generation separate from commit: the protected bodyless generated-value POST returns one transient value, performs no mutation and retains no retrieval state. Browser saved acknowledgement is context-bound UX, not delivery proof or server authorization. Queued credentials require a one-second periodic timer to cancel/wipe non-executing work at the 30-second deadline plus scheduling latency; execution copies then wipes shared inputs, with local wiping after admitted database work returns. Neither timer nor logout cancels admitted commits. Self password/role/delete uses immediate canonical target revocation, not deferred acknowledgement: 401/disconnect is uncertain and requires relogin/inspection before any explicit retry. Generation is independently optionally registered, preserving failure isolation and restart behavior at 23 handlers. No shell restriction change, secret result/history, new executor or 8D.11 work. Implementation is complete, host-tested/build-verified, not target accepted; timer runtime costs remain unmeasured. See contracts, build and attributed test evidence in `docs/phase8d10_implementation.md`.

 The following first-slice exclusions are historical and superseded by slice 2:
