Julian Noble 168a98d85f G-106: powershell console-mode fallback overhaul - punk::console 0.8.0, canonical server script, tests (project 0.17.8) Raw mode on twapi-less windows runtimes made dependable and quiet: lazy singleton server (tsv-shared per process, spawn no longer at module load), parent-pid self-reaping (no orphan pwsh), the 20s keepalive-without-pinger and the first-message listener kill (reader Close disposing the pipe stream) both fixed, disableraw served on no-inputmode runtimes (8.6 path), enable confirmed via live tcl9 -inputmode before return, script resolution env -> argv0 -> module-dir -> embedded copy (pwd fallback gone; kits need no scriptlib on disk). PUNK_PS_CONSOLEMODE_DEBUG=1 for diagnostics both sides. scriptlib/utils/pwsh reconciled: canonical consolemode_server_async.ps1 rewritten (protocol enableraw\|disableraw\|ping\|exit, parent-pid watch, posh-git MIT attribution for the C# snippet), five experiment variants retired (consolemode_server.ps1, _async1.ps1, _async.2ps1, consolemode.ps1, consolemode_enableraw.ps1), README labels the folder. New console suite psfallback.test pins the embedded-copy/file sync and the resolution chain. punk::repl stale comment fix (no behaviour change). Verified per the recipe recorded in the goal detail file: hidden-console selftests on suite tclsh90spr + zipfs kit tclsh90sprzip (25s-idle survival, stop/respawn, zero orphans), live make.tcl-shell and bare-repl sessions driven by injected keystrokes (console mode 0x1E7<->0x1E1 read externally), embedded-resolution forced run, console testsuite 76/76. G-106 acceptance met - achieved flip recorded in the detail file; archive move follows in the next commit.

consolemode_server_async.ps1 (canonical - G-106)

The powershell console-mode fallback server: a persistent named-pipe server that punk::console launches when twapi is absent on windows, to flip the console's line/echo input flags for raw mode. This file is the canonical maintained copy; the module src/modules/punk/console-999999.0a1.0.tm carries an embedded copy (punk::console::system::ps_consolemode_script_embedded) as the last-resort resolution for kits and unusual cwds. Keep the two in sync - the console testsuite src/tests/modules/punk/console/testsuites/console/psfallback.test fails when they diverge.

Key facts (details in the script header and goals/archive/G-106-powershell-consolemode-fallback.md):

Delivered to powershell via -c <script text> with <punkshell_*> placeholders substituted (no script file needed at run time; not subject to ExecutionPolicy). Semicolons after each command are required by that delivery convention.
Protocol: one line per named-pipe connection - enableraw | disableraw | ping | exit.
The server watches the owning tcl process's pid and exits with it (orphan prevention).
Quiet by default; PUNK_PS_CONSOLEMODE_DEBUG=1 in the launching tcl process's environment enables diagnostics on both sides.
The NativeConsoleMethods C# snippet derives from posh-git (MIT - attribution carried in the script).

Superseded experiment variants (consolemode_server.ps1, consolemode_server_async1.ps1, consolemode_server_async.2ps1, consolemode.ps1 - the posh-git original this derives from - and the one-shot consolemode_enableraw.ps1) were retired 2026-07-22 as part of G-106; see VCS history to recover them.

echotest.ps1

Standalone one-line scratch script (write-host "test") - not part of the console-mode fallback machinery.
