## Summary Two CoreScope surfaces treated `0x00` and `0xFF` as ordinary node prefixes, but the MeshCore firmware actively rerolls any identity whose public-key first byte is `0x00` or `0xFF` (see [`examples/simple_repeater/main.cpp:64`](https://github.com/meshcore-dev/MeshCore/blob/6b52fb32301c273fc78d96183501eb23ad33c5bb/examples/simple_repeater/main.cpp#L64)): ```cpp while (count < 10 && (the_mesh.self_id.pub_key[0] == 0x00 || the_mesh.self_id.pub_key[0] == 0xFF)) { // reserved id hashes the_mesh.self_id = radio_new_identity(); count++; } ``` As a result the analyzer was steering new operators toward identities the firmware will silently refuse — `0xFF` is also used as a wildcard flood marker in parts of the routing flow, so this isn't cosmetic. Reporter: **@halo779** (community). ## What this PR does * **`public/prefix-reserved.js`** — small new module, single source of truth. Exposes `isReservedPrefix`, `filterReserved`, `reservedCount`, `markReservedCells`. Firmware citation lives in the file header. * **Hash matrix (1-byte view)** — cells `00` and `FF` get the `.prefix-reserved` class, lose `.hash-active` so the matrix click handler skips them, and pick up an `aria-disabled` + a tooltip explaining why. * **Prefix generator** — random sampling, enumeration fallback, and the "available count" all filter out reserved prefixes. A visible note under the generator card cites `simple_repeater/main.cpp:64` directly. * **Prefix checker** — pasting a reserved prefix or full pubkey now surfaces a red `⚠️ Reserved prefix` alert above the per-tier breakdown. * **`public/style.css`** — `.prefix-reserved` greys + strikes through the cell and sets `pointer-events: none`. * **`public/index.html`** — loads `prefix-reserved.js` before `analytics.js`. ## Tests Red-then-green visible in commit history: * `test-issue-1473-reserved-prefixes.js` — `isReservedPrefix()` semantics (case + multi-byte) and `markReservedCells()` behavior on a mock 256-cell matrix. * `test-issue-1473-prefix-generator.js` — `filterReserved`, `reservedCount` per byte length, RNG-bias simulator showing the generator never returns a reserved prefix, enumeration-first-free skips `00`, and an assertion that `analytics.js` actually wires `PrefixReserved` into the generator. Both added to `test-all.sh`. Fixes #1473 --------- Co-authored-by: clawbot <bot@openclaw.invalid>
