* Fix GetMyExternalIP - was disabled, now uses modern IP echo services

* Fix tunnel disconnect on idle and restore external IP detection

* Filter stale Nostr descriptors

* Sort peers by freshness, fresh first

* Pool: add .btf Stratum listener — miners connect via rendezvous, no port forwarding needed

* btf pool: self-replacing listeners, one per relay, no queuing between miners

* Mining modes: solo/operator/participant — pool server on-demand, participant Stratum client

* Status bar: show external IP and .btf address

* README: clean rewrite, concept-first, minimal

* make linux produces AppImage

* make linux produces AppImage

* Pool dashboard: connect instructions, tabs, share bars

* Perf fixes: GetMyExternalIP threaded, btf listener counted

* Perf fixes: GetMyExternalIP threaded, btf listener counted

* Fix pool payouts: defer until coinbase maturity

* Pool: clean mode switching, IP warning

* Pool: clean mode switching

* Fix gPoolRunning: remove static

* AppImage: use real icon from bitcoin.ico

* Fix exit crash; Mining menu

* Fix exit crash; Mining menu

* Fix exit crash; Mining menu

* Fix exit crash; Mining menu

* Fix exit crash; Mining menu

* Windows build: use mingw32-make

* Add deps-windows target

* Windows build fixes

* Windows build fixes

* Windows makefile: fix obj dir

* Windows: output to repo root

* Windows: bundle DLLs into zip

* Replace wxWidgets with ImGui+GLFW: same build on Linux and Windows

* Fix %I64d that slipped back through rebase (main.h, net.h)

* MinGW: add _mkdir shim for non-MSVC Windows; fix %I64d

* Fix gPoolRunning extern outside ifndef _WIN32

* Remove -lboost_system: boost is header-only in this codebase

* Status bar: copy buttons for IP and .btf address

* Windows: add app icon via windres, strip wx stuff from rc file

* Clean GUI: single Options menu item, bigger font, better spacing, cleaner options dialog; update README

* GUI: embed Roboto font at 16px for clear readability on all platforms

* Windows: windres depends on obj dir target

* Fix balance hidden off-screen: put on own line below address bar

* Windows: inline mkdir in every rule, remove dir target that confused make

* Windows: move all target to top so it's the default rule

* Fix pool server not starting: always start when operator selected, re-sync dialog state on open

* Write debug.log to data directory (AppData/Roaming/Bitflash on Windows)

* Participant miner: use wallet address as username so payouts go to wallet

* Add .gitattributes to lock LF line endings, prevent CRLF drift

* Refactor pool mining to btf-only transport

* Persist pool settings and startup wiring

* Prune stale peers and expose pool queries

* Fix build regressions and add CLI mode/arg parity

* Fix rpc miner stats declaration order

* Centralize pool runtime extern declarations

* Separate operator/participant dashboards and restore peer stats

* Add live telemetry strip and clearer per-mode runtime metrics

* Reduce mining dashboard clutter and remove manual pool entry

* Count only authorized pool miners

* Seed initial pool job on startup

* Use a real share target for pool work

* Switch pool accounting to round-based shares

* Fix nostr pool announcer stats call sites

* Fix pool stats definition order

* Improve pool worker status display

* Add mutex include for participant status

* Replace ImClamp in dashboard layout

* Clarify participant work status

* Log participant status transitions

* Reduce peer discovery log noise

* Add participant status badge

* Track participant auth acknowledgements

* Log and validate pool job delivery
