 # Phase 8D — Incremental web administration plan

+**Latest implementation (2026-09-08):** User-requested **8D.11 implemented, host-tested/build-verified; target sign-off pending**. Accounts fingerprint listing and Ed25519/P256 import/delete/clear use canonical target-checked APIs and the existing dispatcher. Sparse-slot selection regression fixed; 24 handlers/six sockets, no new task/stack-size/queue expansion. Final build 96,076 B RAM / 1,703,685 B flash. [8D.11 record](phase8d11_implementation.md) contains API/bounds, test attribution and pending hardware checklist. Supersedes historical wait-for-8D.11 instructions below; 8D.8–8D.10/M2 remain accepted. No M3 completion or 8D.12 work.

 **Latest target sign-off (2026-09-08):** User reports thorough Serial parameter display/settings and user/account testing, supplies settled boot/full-client-mix evidence, and explicitly says implemented work can be signed off. **Implemented 8D.8–8D.10 are accepted**, including 8D.9 UX and both 8D.10 slices. Supersedes target/signoff-pending statements below, not build/test evidence or restrictions. [8D.10 target acceptance record](phase8d10_implementation.md) contains all six loaded samples, client mix, counters and evidence limits. Full mix at 230400 baud confirms SSH sole writer + USB/two web observers with both admin routes. Final internal/DMA free 32,556/24,800 B, lifetime minima 19,228/11,472 B, largest 23,552 B; isolated failures retained without diagnosis. Exact revision/browser/durations/individual cases are unspecified; no leak-free-soak or reserve approval inferred. M2 stands; full M3/browser-shell parity is not claimed. **Next is 8D.11 only when separately requested; this sign-off authorizes no implementation.**

 **Current slice 2 completion (2026-09-08):** **8D.10 implementation is complete, host-tested/build-verified, not target accepted; target validation/full signoff remain pending.** Create/password/self workflows use bounded 768-byte admission and periodic credential cleanup (30-second deadline plus one-second timer/scheduling latency); admitted executing work is not cancelled. Protected generation is separate before commit, with no retained retrieval. Self revocation may prevent results: 401/disconnect is uncertain, never grounds for automatic retry. Browser-shell restrictions remain unchanged. Review's only finding, missing generated-route registration, is fixed as an independent optional endpoint with failure isolation/restart coverage, **23 handlers/six sockets**. Parent PASS canonical accounts/boundary, parser **294**, cookie accounts **9 plus shared**, serial-settings **10**, transport **25**/tickets **12**, store/serial and diff check. UI agent **57 plus CSP** and route agent lifecycle **15** pass; these are not claims of the parent's additional UI/lifecycle reruns. Parent `pio run` **PASS 25.61 s, 95,908 B RAM / 1,694,237 B flash**, **+80/+9,880** vs slice 1 and **+200/+25,400** vs final 8D.9 UX. Timer runtime costs and heap/stack margins remain unmeasured. [Current 8D.10 record](phase8d10_implementation.md) contains contracts/evidence/target checklist. No sanitizer validation, assets/device/commit/8D.11 work, M2 reopening, prior-phase signoff or reserve approval inferred.
