#Piped characterization of the make.tcl bakelist report and the bake-side selective
#kit-name validation (goal G-121). Runs the WORKING TREE's src/make.tcl under the
#built punk executable's 'script' subcommand with output captured through a pipe,
#and pins:
#  - 'bakelist' exits 0, output is ESC-free (G-113 piped policy), the stable header
#    row is present and the punk91 row carries the expected type/runtime/vfs columns
#    with a deployed state from the documented vocabulary
#  - 'bakelist <kitname>' filters to the named entry and appends the per-kit detail
#    block; unfiltered rows do not appear
#  - 'bakelist <unknown>' exits 1 naming the unknown and listing the configured names
#  - 'bake <unknown>' exits 1 BEFORE any build ("nothing built"), listing the
#    configured names - the no-build guarantee of selective bake
#The row pins are characterization of the current src/runtime/mapvfs.toml kit
#matrix (punk91 = tclsfe-x64 + punk9wintk903.vfs, zip) - a deliberate config change
#legitimately updates them.
#G-024 additions: @group selection, toml parsing exercised through the
#PUNK_MAPVFS_CONFIG env seam (fixture configs - the real mapping is never edited):
#versioned-scheme expansion, strict entry-named config errors, and the legacy
#mapvfs.config deprecation NOTE.
#
#Target executable resolved from env(PUNK_SHELL_TEST_EXE), else <projectroot>/bin/punk902z.exe
#then <projectroot>/bin/punkshell902. Skipped (constraint punkexeavailable) if none found.
