Christopher Van HooseandClaude Fable 5 1b7d793ceb M9: audit pass 2 — 29 verified fixes (nav soft-locks, gate parity, deep sleep, build hardening)

Second 7-dimension adversarially-verified audit over the 08-19 tree.
Headliners: SUB_MAP over a display-only Lua app orphaned the app page
(key-only soft-lock); Back-ladder z-order redesign (CC/power always-
frontmost, confirm-modal deference, Lua key-forward suppressed while a
confirm is up — the send-permission dialog was unanswerable); map pan
flag could go stale across tab jumps/popups; null-close progress rows
now genuinely block the registry dismiss (shared fix); terminal RX
mirror, fullscreen title, wallpaper caption, storage-error guidance
widened to M9; accent/@-mention pickers suppressed (dead chrome on a
touchless board); kb-backlight cache only latches ACKed duties (0xFF
sentinel == duty 255 skipped the first write every boot); deep sleep
actually drops the rails now (display refcount, LEDC pin re-route,
RTC/digital holds) and powers off radio+GPS; TCXO fallback no longer
codifies the disproven 0.0f; RadioLib old-FW patch fail-closes at
link; ENV_SKIP_GPS_DETECT + CORE_DEBUG_LEVEL=0 added to the env.

Full round log in M9_PORT.md 'Audit pass 2 (2026-08-20)'. All four
touch envs (M9, T-Deck, V4-R8, pager) compile clean.

1	# Heltec ThinkNode M9 firmware — custom partition table.
2	#
3	# 16 MB layout with TWO EQUAL OTA app slots so the firmware can self-update
4	# (HTTP OTA via the meshcomod proxy). The app region (app0+app1) is split
5	# evenly at 3.875 MB each — the firmware is ~2.99 MB (2026-08 builds), leaving
6	# ~0.88 MB of growth headroom per slot. Re-check that number at release time:
7	# the slots CANNOT grow later without moving the tiles/spiffs offsets, which
8	# the next paragraph forbids. The tiles + spiffs offsets are UNCHANGED from the
9	# previous (single-big-app0) layout, so an OTA — or a one-time USB re-flash to
10	# install this table — keeps the map tile cache and all user data (prefs /
11	# contacts / channels / chat history) intact.
12	# - app0 3.875 MB (ota_0) ┐ equal A/B slots; OTA ping-pongs between them
13	# - app1 3.875 MB (ota_1) ┘
14	# slippy-tile pack
15	# - spiffs 3.375 MB for user data (/new_prefs, /contacts3, /channels2, chat
16	# history)
