Goal/Acceptance wording updated per user approval (verification runtime need
not be an official release). Upstream f10d91c2d3 fix confirmed merged and
present in TEMP_REFERENCE/tcl9; both G-039 defects addressed. Progress
entries: toolchain policy (zig-only for project integration), known-good 2024
zig build recipe determined and duplicated (zig-out90dup2026), 9.0.5
verification runtime built (tcl905 checkout, build905.zig: fresh-checkout
preconditions tclUuid.h + tclsh.exe.manifest, mingw_unicode_entry_point for
upstream's removed TCL_BROKEN_MAINARGS). Remaining: G-039 kill procedure on
the 9.0.5 runtime.

New goal G-076 (active): adopt the upstream tcl9 dead-console fix (ticket
f10d91c2d3, root-caused in G-039) via a single version gate shared by the
'help tcl' warning and the repl watchdog arming.
- punk::lib 0.4.3: has_tclbug_console_deadspin + pure classifier
tclbug_console_deadspin_applies, gate variable
check::tclbug_console_deadspin_fixed_in (empty = all Tcl 9 windows
runtimes affected). Buginfo dicts gain a mitigated/mitigation axis
orthogonal to level; the deadspin check reports mitigated when
punk::repl >= 0.5.0 is available to the runtime.
- punk::repl 0.5.1: repl::start arms the dead-console watchdog only when
the check reports the runtime affected - recording a verified fixed
release once flips both consumers.
- punk 0.2.6: 'help tcl' renders mitigated warnings subdued (term-grey)
with a "(mitigated)" annotation and the mitigation text; severity
classification unchanged.
- checkbugs.test: classifier truth table, live-check consistency, and
mitigated-axis validation in the generic every-check sweep.
The fixed_in flip is deliberately deferred until a released Tcl passes
the G-039 kill-procedure re-verification (watchdog disabled, clean
script-visible eof exit) - recorded as the goal's remaining acceptance
item.
