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).

Not a mode of app-punkshell. The acceptance is defined by absence (no
shellfilter stacks, no logging side effects, no interactive fallback),
which a package that never loads that machinery guarantees by
construction; app-punkshell''s load-time behaviour (shellfilter stacks
with syslog/file targets writing punkshell_*.log into the caller''s cwd,
logging threads) is wrong for one-shot calls; isolation caps the blast
radius of shell-path machinery. Duplication mitigation: the default punk
shell module/alias environment definition is factored into a shared
module-level definition (punk::aliascore as seed) consumed by both app
packages - share definitions via modules, not launcher control flow.
Package shape previews the G-031 registration model, as app-tomlish
demonstrated.

G-030 (proposed): make.tcl - the first surface a developer sees - parses
subcommands/options via punk::args and showcases the tabled usage for
help and argument errors; every interactive y/n prompt gains a declared
flag equivalent (interactive stdin prompts as today; flag proceeds;
non-interactive stdin without the flag fails fast with usage instead of
hanging or half-aborting) so agents drive make.tcl with arguments rather
than piped y/n; punk::args joins the bootstrap-tracked staleness set.
Degradation is a hard requirement: boot stays self-contained and the
repair commands (check/bootsupport/modules) keep working with plain
fallback help when the bootsupport punk::args or the ANSI rendering
stack is stale/unavailable - this week''s stale-fileutil and
stale-textblock incidents are the cautionary tales.
G-015 detail: recorded the runx -tcl result-shape observation (dict keyed
{result stdout stderr}, no exitcode key unlike exec mode).
G-020 detail: stamped the 2026-07-07 decision - acceptance gates on a
full testable Windows system without requiring other platforms first.

G-015: complete the punk executable `script` subcommand - run a script file
or piped stdin (scriptname optional) in an interp preloaded with the default
punk shell modules/aliases, honest exit codes, no shellfilter transforms, no
interactive-shell fallthrough. Replaces the fragile `...;exit | punkexe`
repl-pipe pattern (currently a stub in punk_main.tcl that only emits stderr
diagnostics). Lean bare-script execution deferred to a later `tclsh`
subcommand expansion.
G-016: extend `dev projects.work` to discover git-based projects alongside
fossil (git has no central registry - enumeration-source candidates recorded
in the detail file).
G-017 (index-only): once G-015 lands, direct agents via repo guidance to
locate sibling projects with a piped projects.work call instead of scanning
the filesystem.
