- new src/tests/modules/punk/mix/testsuites/scriptwrap/multishell.test (9 tests, green on tcl 9.0.3 + 8.7, unix exec case constraint-gated): scriptset wrap via the module-provided punk.multishell.cmd template (payloads + _wrap.toml fixture) - output produced, MULTISHELL magic line, payloads embedded verbatim, configured win32 nextshell present, LF-only endings, byte-identical re-wrap determinism; checkfile 512-byte label/boundary validation reports no label location errors for a fresh wrap AND for the committed bin/runtime.cmd; the runtime scriptset ROUND-TRIP pin - re-wrapping src/scriptapps runtime.ps1+runtime.bash+runtime_wrap.toml reproduces bin/runtime.cmd byte for byte (verified identical before pinning), so hand-edits to the output or unregenerated payload changes both fail; execution smoke - cmd.exe runs the polyglot and dispatches the powershell payload (windows), sh payload execution gated to unix (on windows the shell layer deliberately relaunches via the win32 nextshell)
- guidance strengthened so "fix bin/<name>.cmd" routes to sources: root AGENTS.md bin/ index entry now states the .cmd polyglots are scriptwrap-generated from src/scriptapps; bin/AGENTS.md gains a "Generated polyglot .cmd scripts - never edit in place" section with the 4-step fix workflow (edit payloads/toml, re-wrap with multishell -askme 0, heed checkfile ERRORs, commit source + regenerated output together); src/scriptapps/AGENTS.md documents the scriptset->bin/*.cmd relationship and regeneration command; tests index updated
- context: the polyglot technique is deliberately maintained despite fragility (user direction 2026-07-10) until hiding techniques close in the underlying languages - these pins are the guardrails

The dash-delimited launch package modes of built punk shells (dev/os/src/
internal, implemented in src/vfs/_config/punk_main.tcl) had no agent-facing
record. bin/AGENTS.md now documents the mode grammar and, in operational
terms, the src mode that matters for verifying working-tree changes:
exe-location-based project-root discovery, the source module paths it
prepends, package prefer latest (dev 999999.0a1.0 modules beating
kit-stamped snapshots), and how 'package present' distinguishes a src-mode
session from a plain kit launch. Also records the both-Tcl-generations
interactive verification convention (a Tcl 8.6-based shell plus the current
Tcl 9-based incarnation, deliberately not version-pinned) and the role of
the plain runtime kits under bin/runtime/ for punk-free probes.
Root AGENTS.md Child DOX Index gains the bin/ entry, and .gitignore gains
a !/bin/AGENTS.md negation alongside the other source-controlled bin items
(the /bin/* ignore is why no doc lived there before).
