onContactOverwrite() (the contact-table-full LRU eviction path) deleted the
contact's blob and notified the companion app, but never called the new
onContactRemoved() cleanup -- so a Favourites Dial slot, Locator target, or
Live Share target could still go stale, just via the silent auto-evict path
instead of an explicit removal. This is likely the main real-world cause of
the "(gone)" tile the docs described, since auto-eviction happens far more
often than an explicit CMD_REMOVE_CONTACT.
Also sync the two docs that described the old (now wrong) behaviour:
Locator's "survives delete" claim, and Favourites Dial's "(gone) until
reassigned" claim.

Squash merge of feat/location-beacon-alerts-autopause (v1.21).
Features:
- Live Location Sharing — broadcast position as movement-gated [LOC]
messages to a channel or contact; live shares show as map pins with
distance/bearing in Nearby Nodes and a status-bar indicator. [LOC] is
parsed in DMs, channel messages and room messages; DM shares name the
sender.
- Locator (geofence) — arm a geofence around a saved waypoint or a person
(live [LOC] or last-known position), alert on arrive/leave or near/far,
with an optional homing beeper (gated to arrive/both modes). Arm from
Tools > Locator, Nearby Nodes, or Waypoints; target picker lists
favourites first, clearable via a "None" entry. Active target is drawn
as a flag on the map.
- One active target shared across Locator / Navigate / Map via a single
resolver (resolvePersonPos / activeTargetPos) that prefers a live
[LOC] share over the last-advertised GPS fix.
- Follow live contacts — Navigate to a live-sharing contact follows them
as they move and adds an ETA line; quick-share your own position from
the Map.
- Map & status-bar upgrades — home mini-map gets a north marker, scale
tick, and a connected trail line (was disconnected dots); status line
shows tracked-node count, an arrow + distance to the active Locator/Nav
target (falling back to the nearest live-tracked contact); GPS fix icon
in the top status bar, shown only on GPS boards with GPS enabled.
- Trail auto-pause — recording freezes on stops (banking elapsed time,
breaking the map line across the idle gap) and resumes on movement
without ending the session.
- Streaming trail simplification — GPS points are simplified in-stream
via a fixed-corridor (Reumann-Witkam) pass tuned for fidelity: straight
runs collapse to their endpoints, curves stay bounded to the Min-dist
tolerance, so the 512-point buffer covers a far longer route than a
flat point budget would suggest.
- Collapsible Tools (Location / Comms / System sections, fold-in-place
like Settings) and page-indicator icons on the home carousel.
- Waypoint coordinate editor — add a waypoint by scroll-editing lat/lon
digit by digit.
Fixes:
- Critical: low-heap hang and contact loss on RAM-tight builds. Halved
message-history scrollback rings (recovering ~14 KB free heap) and
made contacts/channels/prefs persistence atomic (temp file + rename),
so an interrupted save can no longer corrupt or wipe the store.
- Serial.write() bounded so a stalled USB host can't hang the device.
- Nearby Nodes: live [LOC] senders respect the type filter, sort by
shared position, and the list refreshes so live shares bubble up.
- Map: live contacts are labelled before waypoints.
- GPS status icon hidden when GPS is off in Settings.
- Splash screen no longer truncates a pre-release tag's own dash (e.g.
v1.21-rc1) when stripping the build's commit-hash suffix.
- Null-guarded the Locator target picker; clamped loc-share channel
index on load.
Under the hood:
- -Os size optimisation on the e-ink and GAT562 30S solo envs.

README:
- Fix typo "offical" → "official"
- File names in Firmware Variants table now match workflow output
(solo-<version>-oled.uf2 / solo-<version>-eink.uf2)
- Un-comment the E-ink Display section (now fully supported)
- Clock Screen: "sensor values" → "data fields" (covers Batt%, Nodes, Msgs)
- Tools Screen: mention nearby nodes and auto-advert in the highlight
- Promote Screenshot Tool to its own top-level section (was buried under
Contributing); fix `uv run tools/screenshot.py` invocation path
Docs:
- favourites_dial: document the 3rd pin-picker tier (all chat contacts
fallback) added in 0e0e5b93
- clock_screen: Altitude source clarified — onboard sensor (GPS or
barometric), not always GPS
- message_screen: blank lines around image tables that were inlined
Code:
- UITask.cpp: rename leftover plus_y/plus_label locals to solo_y/solo_label
in the splash-screen Solo banner
Workflow:
- workflow_dispatch builds previously labelled firmware with the branch
name (GITHUB_REF_NAME). Resolve BUILD_VERSION to the tag when run on a
tag push, else dev-<short-sha> so manual runs produce
solo-dev-abc1234-oled.uf2 etc.
Cleanup:
- remove stray docs/solo_features/settings_screen/set_scr_1_eink copy.png
