- three new backend modules under src/modules/opunk/console/, base ::opunk::Console and punk::console UNCHANGED (the G-001 acceptance constraint - verified diff-clean):
* opunk::console::test / ::opunk::TestConsole - deterministic channel-pair test double: fixed size via -columns/-rows, is_console_or_tty/can_respond 1 (settled value wins), at_eof = plain chan eof with NO probe (pending bytes never consumed - pinned). The console seam identified by the G-044 repl characterization work
* opunk::console::ssh / ::opunk::SshConsole - socket-carried terminal sessions: construction-time capability (detection is the wrong tool - per goal detail), chan-eof without byte-consuming probes, size via the registered ANSI size-query provider over the connection. Flagship test: a scripted remote terminal answers CSI 6n over a socket pair and size resolves 100x30 through punk::console machinery querying the socket
* opunk::console::tk / ::opunk::TkConsole - Tk text widget as terminal: widget path in the inherited in/out slots (documented non-channel reuse), terminal_class tk-text, size from widget char dims, at_eof via backend marker (opunk::console::tk::set_eof) or widget destruction; no Tk require at module load. Verified live under punk91 src (the tk-loading experiment kit)
- voo -extends subclassing pattern recorded in opunk/AGENTS.md: children inherit public accessors + field INDEX variables (not parent-private my.* accessors) - constructors initialise inherited private fields via index vars, method bodies use parent public accessor methods; virtual dispatch via the slot-0 tag needs no base changes
- tests: modules/opunk/console backends.test (8 tests: dispatch, spec_resolve acceptance of subclass values, probe-free eof, settled-capability precedence, ssh capability/eof/size-over-socket/settled-0-no-emission, tk gated behind env PUNK_TEST_TK=1) - 7 green + tk skip on tcl 9.0.3 and 8.7; tk case verified standalone under punk91
- goal detail records progress + remaining work (repl -console launch wiring, output-channel parameterization, interactive acceptance verification); goal stays active

G-001 pluggable console backends for non-detectable terminals (ssh channel, tk widget) via ::opunk::Console subclasses. G-002 non-nested subshell with console targeting and inter-subshell comms, including thread::send -async routing to the code sub-interp and the canonical launch API design (subshell as sole entry point, interp alias as context signal). G-003 configurable resource limits (command-count, time via interp limit) and sandboxing spectrum (interp hide/expose/alias, safe::interpCreate) on subshell interps, downstream of G-002's asymmetry fix.
