The suite and seven libs assumed a GNU userland: `cmd | grep -q` under
pipefail (grep exits at the first match, the producer takes SIGPIPE,
rc 141 → 15 false "merged into" FAILs in gitflow-test), `sed -i` with no
suffix, `wc -l` padding compared as a string, `stat -c`, `touch -d`,
`realpath -m` (gstack-links refusal never fired), bare `timeout` off the
sanitized PATH (design gate READY BUT UNVERIFIED), `grep -oP` (update-all
emptied the plugin list). Thirteen suites were red on this machine.
Portable forms on the native userland of both OS: producer captured out
of the pipeline, `sed -i.bak` in tests and a temp-sibling `sed_profile`
on the user dotfile, `tr -d ' '`, python3 perms, `touch -t`, a
`realpath -m` emulation that refuses `..`, perl `alarm` for the 15 s
bound, `sed -n` token extraction. Regression tests: gstack-links T4b,
doctrine-citers Alphabet/Alpha flip, profile-set-managed T18 (failing CLI
no longer aborts `set`), new portability-census suite over the tracked
shell files. Linux run deferred (see TODO).
Nine gstack skills leave every profile (ship is trunk-based on Gitea,
land-and-deploy auto-merges and deploys, setup-deploy, autoplan reads
paths that do not exist here, context-save has no restore, learn is an
unused parallel store, careful and guard hooks never fired, design-shotgun
needs an absent OpenAI key). lib/gstack-removed.sh is the single denylist;
profile.sh gstack on and toggle-external.sh enable gstack skip it.
full now carries everything every other profile carries (user rule), minus
the parked make-pdf, diagram and 21st-ai/ui-explore/ui-review, which live
in the new max profile together with pr-review-toolkit. The 21st trio also
leaves web, web-full and design (redundant with impeccable + ui-ux-pro-max).
lib/tests/profile-census.test.sh asserts the invariants live and on a
baseline fixture plus one mutant per invariant; gstack-removed.test.sh
covers both restore paths.
