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).
(1) lib/doc-shape.sh — deterministic shape oracle re-checks each LLM-classified
MINOR patch before the silent auto-commit; a shape-suspect patch (added heading
/ oversize / new file / non-doc) escalates to the EXISTING SIGNIFICANT gate.
Genuine MINOR still auto-commits (zero friction, BDR-036 preserved). A structural
floor under the LLM call, not a semantic SIGNIFICANT-detector (BDR-040).
(2) lib/doc-commit.sh — guard the commit itself: a rejected git commit (pre-commit
hook / protected branch / signing) now fails loud with exit 5 + empty stdout,
instead of a false "committed" + the previous HEAD's hash + exit 0 that left docs
silently uncommitted (LRN-071, 3rd occurrence of the swallowed-commit pattern
after LRN-066 and LRN-068/BLK-012).
Wired doc-syncer STEP A4 (whole-set escalation: no=revert all, select=keep subset)
+ doc-commit.md (rc-5 consumer row + ACKNOWLEDGMENTS coherence).
TDD RED->GREEN: run-doc-commit.sh 32/32, run-doc-shape.sh 19/19, behavioral C/D.
shellcheck clean. Branch-guard (3) deferred.
