feat(e2e): scripted app bring-up — onboarding bypass, trust dialog, sim traceroute knob - #76

Conversation
On a PKI firmware build a node's identity is derived, not assigned: my_node_num = crc32(x25519_public_key) (NodeDB.cpp::createNewIdentity), and every client paints the node with the low 24 bits of that number read straight as RGB (Meshtastic-Android NodeColors.kt, Meshtastic-Apple Color.swift agree, foreground included). Both steps are one-way, so a chosen id -- or a chosen colour, which is the same thing over fewer bits -- means searching the keypair space. mvgrind (https://github.com/miketweaver/mvgrind) does that on the GPU. Five tools. Grinding is gated on the binary ($MESHTASTIC_MCP_MVGRIND or PATH): vanity_grind_start / _poll / _stop background job, mvgrind capability vanity_preview key -> id + colour, pure, core vanity_apply write the key to a radio, core preview and apply stay core deliberately: a key ground on another machine (or a friend's GPU) is still inspectable and applicable here. Every hit is re-derived by this repo's own RFC 7748 X25519 ladder + zlib.crc32, sharing no code with the grinder's OpenCL kernels -- verified: false means the key does not produce the id it claims, which is a grinder bug, not a near miss. No new dependency: one scalarmult per call, ~1 ms. Two firmware traps the apply path encodes rather than discovers: - The write must CLEAR public_key. AdminModule.cpp only calls generateCryptoKeyPair(private_key) when the incoming public key is empty; echo the old 32-byte key back and neither keygen branch fires, so the node keeps its old NodeNum and a DH key that no longer matches. The write appears to succeed and changes nothing. Pinned by a unit test on the proto build. - lora.region must be set. generateCryptoKeyPair refuses to derive while the region is UNSET, making the whole write a silent no-op. apply_key is confirm-gated and destructiveHint: it replaces the identity, the old NodeNum is dropped from the node's own DB, and peers must re-learn the key. It refuses an unclamped key (the firmware signs with a clamped copy of the scalar, so an unclamped one yields unverifiable signatures), reports the previous node id, and reads my_node_num back after the self-reboot -- which is also the empirical check that the build has PKI keygen at all. The build/flash job registry moves to jobs.py so the grinder shares it instead of growing a second one; build_poll/flash_poll keep their "env" key. Hits are private-key material: 0600 files under the data dir, and returned inline because that is what apply consumes. SECURITY.md and docs/vanity.md say so. doctor reports the binary and prints the build command, including the one-line macOS getrandom-probe fix upstream currently needs. Verified against an Apple M4 (~92 M keys/s, full 8-digit id ~48 s mean): real grinds for !dead5d54, !dc801051 and crimson+/-6 all re-derive correctly here.

The doc showed a different patch (skip the probe, fall through to /dev/urandom) than the one actually submitted. Match miketweaver/mvgrind#2: seed from getentropy() on Apple, same fails-closed guarantee without depending on /dev being present. doctor's hint names the PR too.

…im traceroute knob
A UI-driving session hand-walked onboarding and the manual-IP dialog because
the fast path wasn't where an agent looks first. Three fixes:
- deeplink() now sends MainActivity's debug-only EXTRA_SKIP_ONBOARDING with
every deep link — a no-op on release builds and completed onboarding, and
skips the whole intro flow on fresh debug installs.
- connect_app_to_tcp() accepts the trust dialog that builds after 2.8.1 pop
on link-initiated connects ("Connect to this device?"), instead of stalling
through the 20 s confirm window into the tap fallback.
- The sim's request→response traceroute pairs get a profile knob,
traceroute_pairs_per_hour (default 12, unchanged) — the app pops a modal
over whatever is being tested for each response addressed to the observer,
so UI sessions set it to 0. Regression-tested; the bot plane's own
traceroutes_per_day knob is unchanged.
- The e2e skill now leads with the scripted bring-up recipe so the manual
tap-dance stops being the discoverable path.

📝 WalkthroughWalkthroughThe change adds onboarding bypass and trust-dialog handling to Android deep-link startup. It also adds a configurable traceroute emission rate and documents the debug app bring-up workflow. ChangesDebug UI and replay behavior
Estimated code review effort: 2 (Simple) | ~10 minutes Merge Risk: 🟡 Moderate · up to The scripted bring-up now automates Android connection approval, but separate UI reads can observe different screens and report success before the connection is actually accepted. This could cause test automation to continue with an unestablished connection, so the current head is not merge-ready until the polling uses one UI snapshot per cycle and covers the transition with a regression test.

CodeRabbit caught a real gap in the fast path: while the trust dialog is up, the UI dump contains only dialog nodes, so "Not connected" is absent for the wrong reason — a failed accept tap could read as a successful connection. The connectivity check now runs only in polls that did not see the dialog, with a regression test pinning the stuck-dialog case.
