* Right-size nRF52 heap tiers after 2.8.0 heap-exhaustion field reports
Field reports on 2.8.0 show nRF52840 devices at 99% heap (114/115 KB)
within minutes of boot; operator new asserts on OOM, so these devices
are one allocation from a reboot. The 2.8.0 cache sizing ladders gave
nRF52 the largest non-PSRAM tiers on the assumption that a BLE-only
part has a roomy heap - the arena is actually ~125 KB shared with the
FreeRTOS task stacks.
Per-target retiers (nRF52840 unless noted):
- Traffic Management cache 1000 -> 250 entries (10 KB -> 2.5 KB); the
unclassified fallthrough drops 1000 -> 400 to match the classic-ESP32
tier (also affects RP2040/RP2350)
- Warm node store 200 -> 100 entries (8 KB -> 4 KB); the non-XXAA
fallthrough drops 320 -> 100 so an unclassified RAM-constrained part
can't boot-allocate 12.8 KB
- MESSAGE_HISTORY_LIMIT 20 -> 10 (text pool 4.4 KB -> 2.2 KB), the tier
classic ESP32 already ships
- MAX_RX_TOPHONE 32 -> 16, shrinking the static packet pool 70 -> 54
slots (~6.6 KB of .bss returned to the heap arena)
- PacketHistory hash index off arch-wide (1 KB); O(n) over 240 records
is negligible at LoRa packet rates
- OLEDDISPLAY_REDUCE_MEMORY arch-wide (~1 KB OLED back buffer); the five
TFT variants -U it because TFTDisplay.cpp needs buffer_back for
dirty-window diffing
- Drop the stale "for testing" 1024-entry TMM override on T1000-E
Measured on rak4631: heap arena grows 124,572 -> 131,180 B and boot
allocations drop ~15.7 KB, roughly +22 KB free heap on the field-report
device class.
Migration: the nRF52840 warm flash ring replays through place() (LRU),
so the newest 100 identities survive the shrink; the file backend
rejects oversized snapshots cleanly (new test covers this). Native
suites pass (536/536 Docker, 13/13 native-macos warm store); rak4631,
heltec-mesh-node-t114 (TFT) and tracker-t1000-e build green.
* Add central memory-class ladder (MemClass.h) with fail-safe-small defaults
The 2.8.0 nRF52840 heap exhaustion happened because each RAM-sized cache
picked its per-platform tier from its own chip #ifdef ladder, and every
ladder's fallthrough default was its largest non-PSRAM tier - nRF52 was
never named, so it silently got 1000-entry caches on a ~115 KB arena.
This introduces src/memory/MemClass.h: a single MESHTASTIC_MEM_CLASS
(TINY / SMALL / MEDIUM / LARGE) ranked by usable app heap after platform
overheads, with the deliberate property that an unclassified chip lands
in SMALL - a new target boots with small caches until someone opts it up
in one visible place.
The TMM cache, warm store, MAX_RX_TOPHONE and MAX_SATELLITE_NODES
ladders in mesh-pb-constants.h now key off the class; branches pinned by
something other than RAM stay explicit and say why (nRF52840's SoftDevice
arena, RP2040's warm.dat watchdog bound). MAX_NUM_NODES intentionally
stays separate - it is flash-shaped (nodes.proto vs LittleFS), not
heap-shaped.
A per-class MESHTASTIC_BOOT_CACHE_BUDGET static_assert now covers the
three big boot-allocated caches, so the next cache-adding PR that would
blow a small platform's budget fails to compile instead of exhausting
heap in the field.
No values change for any existing target: rak4631, tbeam, rak11310 and
wio-e5 build byte-identical before/after; all ladders remain
#ifndef-guarded so variant overrides keep working.
* Address review: fix RP2350 class-table doc, add PacketRecord static_assert
- MemClass.h's class table claimed RP2350 was MEDIUM while the mapping
ladder classifies it SMALL (with RP2040) - the table now matches the
ladder, with a note that RP2350 is a MEDIUM candidate whenever someone
wants to tune it up (kept SMALL here so this header stays a behavioral
no-op).
- The boot-cache budget comment referenced a static_assert pinning
PacketHistory::PacketRecord at 20 B that did not exist (only a layout
comment). Add the real static_assert so the budget math in
mesh-pb-constants.h fails to compile if the record layout changes.
Also merges develop (the base #10898 landed there as a squash, which is
what made this stacked branch conflict); develop's mesh-pb-constants.h
is byte-identical to this branch's base, so the resolution keeps the
MemClass ladder unchanged. rak4631 and wio-e5 build green;
test_packet_history 47/47.
* Address review: share PACKETHISTORY_MAX, trim policy comments
- Hoist PACKETHISTORY_MAX from PacketHistory.cpp into
mesh-pb-constants.h (next to the MAX_NUM_NODES it derives from) so the
constructor clamp and the boot-cache budget static_assert use one
definition instead of hand-mirrored arithmetic that could drift. The
expression stays valid where MAX_NUM_NODES resolves at runtime
(ESP32-S3, portduino); the pointless 2.0 double math becomes integer.
- Trim the MemClass.h header (36 -> 16 comment lines) and the budget /
sizing-policy comments per the repo comment-length guideline, keeping
the class table, the fail-safe-small rule, the override mechanism, and
the include-order constraint.
rak4631 (compile-time MAX_NUM_NODES) and heltec-v3 (runtime) build
green; test_packet_history 47/47.

* Drop stale OLEDDISPLAY_REDUCE_MEMORY -U on t114 / mesh-solar-tft
Only USE_TFTDISPLAY variants (t1, t096, wismeshtap) compile
TFTDisplay.cpp and need the lib's buffer_back; t114 and mesh-solar-tft
render through the meshtastic-st7789 driver, which handles the
reduced-memory configuration fine - as #10894 (merged from develop)
already established by defining the flag there. Remove the -U guard and
the per-variant -D (redundant with the arch-wide define in nrf52_base
on this branch). Both variants verified building.

I thought git would be smart enough to understand all the whitespace changes but even with all the flags I know to make it ignore theses it still blows up if there are identical changes on both sides.
I have a solution but it require creating a new commit at the merge base for each conflicting PR and merging it into develop.
I don't think blowing up all PRs is worth for now, maybe if we can coordinate this for V3 let's say.
This reverts commit 0d11331d18.

* Make RAK4631 nodes power back on deep sleep
The devices will hang if the VBAT goes under 1.7V (Brown-out reset) and
they will never come back unless power supply goes completely off.
This kills unattended nodes.
Using the SystemOff the LPCOMP we can get the nodes back again when
power comes back, even if VBAT goes under 1.7V, which moreover is more
unlikely because the device is off.
* Adding support for heltec t114
And moved particularities to variant.h
* Remove old cpp comment that belongs to variant.h
It was a leftover.
