Stage 4 - documented overlay semantics implemented (commandset::layout 0.2.0):
layout_materialize resolves a layout to its overlay chain (vendor tier then
custom tier per store+vendor, <name>@<base> derived-layout folders expanding
their base chain first, cycle-guarded) and composes multi-folder chains into a
disposable staging dir applying <item>.anti deletion markers (zero-byte marker
files recommended - committable, unlike the originally documented empty marker
folders, which are also accepted). Single-folder chains with no markers are
used in place, so punk.project (store and zipfs modpod) behaviour is unchanged.
project.new (commandset::project 0.4.0) copies from the materialized path and
the layout listing/scanning commands show the effective merged view.
Fixtures: punk.othersample is now a live derived layout (new custom-deck
fauxlink ref + .gitignore.anti demo marker); extra.txt/store README rewritten
to the implemented semantics. New tcltest suite
src/tests/modules/punk/mix/testsuites/layout/materialize.test (20 tests).
Anti markers deliberately stay a plain filename convention rather than
tag-bearing fauxlinks: a fauxlink is a reference tooling may follow (fcat
auto-follows), a marker is a tombstone with no target.
Stage 5 - retirements and generated-project version seeding:
- The empty unimplemented child-side src/PROJECT_LAYOUTS_CREATE_FROM_... marker
folder is deleted along with its project.new and make.tcl sync exclusions.
- The vendor/custom x _project matrix collapses for layouts: custom/<vendor> is
the one override level; _project folders join no overlay chain (the
pseudo-vendor remains for decktemplates module/utility templates only).
- project.new seeds generated projects post-materialization (only-if-missing,
never from payload): punkproject.toml ([project] name + 0.1.0), a matching
CHANGELOG.md ## [0.1.0] header, and punkorigin.toml - an interim generation
provenance baseline (utc, layout name + resolved store target,
punk::mix::templates version, punkshell version when derivable, origin path)
for the G-027 pull design to adopt (noted in G-027).
Also: script-mode/programmatic project.new robustness (explicit shellrun
require; punk::mix::util askuser/do_in_path/foreach-file fully qualified -
the util:: shorthand exists only after cli commandset import). Includes the
concurrently-landed (other session, previously uncommitted) 0.3.1 early
module-name validation fix in project.new, shipped within the 0.4.0 bump.
G-087 flipped achieved 2026-07-19 (verification in the detail file; archive
move follows in the next commit). punkshell 0.16.0 -> 0.17.0.
