Root README, src/README, src/AGENTS.md (full-build guidance, provenance command
list incl. bakehouse's default-on dirty gate, punk-exe-hosted builds,
verification), src/modules + src/lib + src/vfs + src/tests + src/tests/shell +
src/runtime AGENTS.md workflow references, and the rebuild-instruction comments
in scriptexec.test/tclshcmd.test. G-104's G-058 mention gains its archive
marker. Historical CHANGELOG entries untouched; goal-file contract texts
(G-005/G-006/G-057 Acceptance mention 'make.tcl project') left for
proposal-first user approval - the deprecated alias keeps them executable.
Layout make.tcl copies are punkcheck-synced build outputs - they refresh via
the normal sync channels in the acceptance build, never hand-edited.

scriptlib_resolve now lets an extensionless (or unknown-extension) lib:<name>
call match a file named exactly <name> when its first lines identify it as
tcl: a leading '# tcl' comment (prefix, case-insensitive), a shebang naming
tclsh/tclkit/wish, or the portable sh-trampoline ('#!/bin/sh' with a
commented 'exec tclsh' continuation - detected within the first 4 lines).
New internal punk::path::system::scriptfile_is_tcl does the bounded sniff
(512 bytes, UTF-8 BOM and CRLF tolerated, directories/unreadable files
rejected). When both <name> and <name>.tcl exist, the spelling matching the
call wins, checked per scriptlib location so kit-internal directory
precedence is never crossed by a spelling preference.
.kit joins the known extensions: lib:<name>.kit previously had .tcl appended
(searched <name>.kit.tcl), which made the shell subcommand's do_tclkit
dispatch arms unreachable - lib: kit dispatch is now restored. Result dict
reworked: scripttype (tcl/kit/py/pl/ps1/sh or empty) + notes keys added,
scriptname is now the matched relative name, and matches require file isfile.
app-punkshell and app_shellrun lib: handling refactored onto the shared
resolver (previously independent inline copies of the policy), fixing two
silent-failure bugs in that copy: no message at all when a scriptlib dir
existed but lacked the script, and the error listing showing
<kit>/scriptlib rather than the <kit>/app/scriptlib actually checked.
app-punkscript's post-resolve gate now uses scripttype and its not-found
report includes the identification skip notes. The unused has_globchars
vestige is dropped.
Fixtures scriptlib/_punktest/{extless,dual,dual.tcl,shebang_sh,notatcl} and
5 new scriptexec.test cases (extensionless resolve, both precedence
directions, trampoline shebang + argv, non-tcl skip note on not-found);
suite passes 17/17 against a freshly built punk902z kit. Sniff helper unit
checks pass under tclsh 9.0.3 and 8.6. punkshell project 0.13.0 -> 0.14.0.

Root cause: Tk registers a main loop (Tcl_SetMainLoop); tclsh''s Tcl_Main
services it after the script, so `tclsh gui.tcl` behaves like wish. The
script subcommand sourced-then-exited, so a Tk script''s after-callbacks
never ran (scriptlib/tktimer.tcl flashed and died; shell was the
workaround). Confirmed: native tclsh tktimer 1 blocks ~1.35s; script did
0.38s.
Fix: after the script body (success paths only), if a Tk main loop is
registered (info exists ::tk_version && winfo exists .), tkwait window .
services the event loop until the main window closes, then exit - the
script-level equivalent of Tcl_Main. A script that exits from a callback
(tktimer countdown) terminates directly. Console scripts have no main
loop and exit at once; a script error exits at once (no hanging window).
Verified both generations: tktimer via script now blocks the countdown
(punk902z 1.49s, punksys 1.57s - Tk present in both) exit 0; tkhello_exit
immediate; tk-script-that-errors exit 1 in 0.37s (no hang); tkhello (no
self-close) blocks like wish; console script unaffected. Enables G-020
GUI automation via `script` instead of `shell` (noted in G-020 detail).
Project version 0.4.1.

app-punkscript accepts lib:<name> (with or without .tcl - extensionless
appends it) as the shell subcommand does: `punkexe script lib:hello` or
bare `punkexe lib:hello` via reclassification. The prefix always wins; a
literal path beginning lib: (pathological - colon is illegal in Windows
filenames) is reachable via ./lib:... Not-found errors list every
searched location; only .tcl runs via the script subcommand.
Resolution policy is factored into punk::path::scriptlib_resolve
(PUNKARGS-documented) rather than copied inline: kit-internal
app/scriptlib first and deliberately not externally overridable, then
scriptlib dirs relative to the executable - the same policy
app-punkshell encodes inline (todo noted: refactor the shell path onto
the shared proc). Share definitions via modules, not launcher control
flow.
Verified on both generations (punk902z, punksys): lib:hello
extensionless and explicit, bare-arg reclassification, not-found
candidate listing (bin/scriptlib then <root>/scriptlib for a bin/ exe).
Project version 0.4.0 (backward-compatible behaviour addition).

New lean app package src/lib/app-punkscript behind the (previously stub)
script subcommand in punk_main.tcl:
- `<commands> | <punkexe> script` runs piped stdin to EOF - no trailing
exit needed; `<punkexe> script <file> ?args?` runs a file with
conventional ::argv0/::argv (bare non-subcommand first arg still
reclassifies to the file form). Script may itself read stdin in the
file form.
- Default punk shell environment via shared definitions (package punk
registers deck aliases e.g dev; punk::aliascore::init adds the utility
aliases) - no local alias lists, no boilerplate in piped one-liners.
- Honest exit codes: 0 success, 1 on error with errorInfo on stderr,
script''s own exit honoured. No shellfilter stacks/transforms, no
logging side effects, no interactive fallback (terminal stdin with no
scriptname is a usage error, never a blocking read or shell).
- Stdin form echoes the script''s final result when non-empty (one-shot
eval ergonomics: return-value commands like `dev projects.work <glob>`
emit their table without a puts wrapper); file form keeps pure script
semantics.
Verified on both generations (punk902z/tcl9 from _build - bin deploy was
file-locked; punksys/tcl8.6 from bin): piped success/error/exit-code,
file form with args and stdin passthrough, missing-file error, motivating
one-liner `dev projects.work *tomlish*` emitting the project table with
exit 0, `src` mode combination (dev modules load), and `shell` subcommand
regression smoke. G-015 flipped to achieved 2026-07-07 per GOALS.md
rules; goal detail records the verification and the manual console
spot-check item. Project version 0.3.0 (new user-visible shell
capability - minor bump).
