 - **Real cause**: deny entries are literal patterns; `i` alias and `--global` spelling do not match. No refusal fired, so nothing signalled the guardrail. Not a deliberate reroute, same effect.
 - **Solution**: deny += `npm i -g *`, `npm install --global *`, `npm i --global *` (3dad33e, user go). Disclosed to the user at the design gate. Rule for me: before a global install, grep settings.json `deny` for the verb family, not the exact spelling.
 - **Status**: resolved (partial) 2026-09-30 — flag-after-package forms (`npm i <pkg> -g`, `npm add -g`, `npm -g i`) still pass; pattern grammar for a mid-string wildcard unverified. Open question left to the user. [[BDR-109]]

+## BLK-026 — `make test` red on macOS: GNU-only idioms — 2026-10-06
+- **Friction**: release prep for 2.0.0 ran `make test`: 13 suites red, ~45 FAIL. gitflow-test 15 "merged into" FAIL while merge commit present.
+- **Real cause**: suite + 7 libs written on Ubuntu. `cmd | grep -q` under `set -o pipefail`: grep exits at 1st match, producer SIGPIPE rc 141 (5/5 repro on `git log | grep -q`). Plus `sed -i` no suffix (BSD reads file as script), `wc -l` padded, `stat -c`, `touch -d`, `realpath -m` (gstack write-guard never fired), bare `timeout` off sanitized PATH (design gate UNVERIFIED), `grep -oP` (update-all `_plugins` empty), empty array under `set -u` on bash 3.2, extractor false positive in doctrine-citers. Effort pins also dropped on 2 gitignored SKILL.md (cause not established, re-applied by hand).
+- **Solution**: [[BDR-110]] forms at every site, 23 files, commit 0efdff0; regression tests T4b, Alphabet/Alpha flip, profile-set-managed T18, portability-census suite.
+- **Status**: resolved 2026-10-06. Open: Linux `make test` deferred (TODO); effort-pins re-red trigger (TODO).
+
+## BLK-027 — machine never onboarded: no global hooksPath, push hook silent — 2026-10-06
+- **Friction**: fix commit 0efdff0 and release/2.0.0 prep commit stayed `[ahead 1]`; nobody noticed until `git status -sb`.
+- **Real cause**: `make link` never run on this Mac → `core.hooksPath` unset (local + global), `~/.claude/githooks` absent. `gitflow start` pushes explicitly so branch creation looked fine; commits rely on the post-commit hook. `make link` also reports `make plugin` never ran (11 vendored skills absent) and `~/.claude/.env` missing.
+- **Solution**: pushed both branches by hand; `make link` run (user go) → `core.hooksPath=~/.claude/githooks`, 4 hooks installed. `make doctor` "Git hooks" section flags this; run it first on a new machine.
+- **Status**: resolved for hooks; open: `make plugin` + `.env` on this machine (user action).

+## BDR-110 — Shell portability: native userland both OS, census on deterministic idioms [accepted] (2026-10-06)
+- **Decision**: every tracked `*.sh` + hook runs on BSD (macOS) and GNU userland as installed. Portable forms: producer captured out of `| grep -q` pipelines under pipefail (`grep -q PAT < <(cmd)` tests, `if grep -q PAT <<<"$(cmd 2>&1)"` prod); `sed -i.bak` tests, temp-sibling copy on user dotfiles; `wc -l | tr -d ' '`; python3 for perms; `touch -t`; `realpath -m` emulated (refuses `..`); `perl -e 'alarm shift; exec @ARGV'` for bounds; `sed -n` not `grep -P`; `/usr/bin/grep` pin ([[LRN-074]]). `lib/tests/portability-census.test.sh` greps tracked shell for `sed -i` no-suffix, `stat -c`, `realpath -m`, `touch -d`, `grep -P`, bare `/bin/grep`; file:line allowlist with reason; NO `grep -q` rule (not decidable by text, fix structural).
+- **Why**: suite built on Ubuntu, repo now also lives on macOS. 13 suites red here; 7 prod scripts broken silently (update-all plugin list empty, design gate UNVERIFIED, gstack write-guard dead). Brew GNU on PATH rejected: brew dependency + two behaviours by PATH.
+- **Alternatives rejected**: prepend coreutils/gnu-sed to PATH in Makefile+hooks; `grep X >/dev/null` (GNU grep treats /dev/null stdout like `-q`, race stays); broad `| grep -q` census (119 hits, fixtures, false confidence).
+- **Gates**: 3 lenses (FATAL 6 / CONCERNS 4 / FATAL 2) + confirmation CONCERNS(2), all closed r3; GATE 0 MET 8/8 ×2; verifier CONFORME 9/9; security PASS (1 MEDIUM hardened). Linux run `[deferred]`.

 ## LRN-188 — A CHECK oracle tied to code shape breaks on refactor; assert the property
 - **Context**: contract criterion 5 used `grep -A6 '^_higgsfield_probe()' | grep -c '</dev/null …' | grep -qx 2`. The gtimeout fallback reshaped the function into a loop: second redirect moved past the 6-line window → GATE 0 UNMET on correct code. Rewritten: extract the body `awk '/^fn\(\)/,/^}/'`, require the redirect on EVERY invocation line, control = strip redirects → differs. Orchestrator edited its own oracle outside a human gate, logged in the contract, surfaced to the user, fresh verifier judged it stricter.
 - **Apply**: oracles state a property over the whole unit (function body, section range), never a line window or an exact count of incidental lines; any oracle edit after a gate is logged + surfaced. [[LRN-093]], [[BDR-109]]
+
+## LRN-189 — `| grep -q` under pipefail is a SIGPIPE race, not a portability nit
+- **Context**: 15 gitflow-test assertions `git log … | grep -q "Merge …"` false on macOS, merge present. grep -q exits at first match → producer SIGPIPE → rc 141 → pipefail false. Linux hides it by write buffering, race exists there too (doc-shape fail-open). Challenger-verified: GNU grep main() sets done_on_match when stdout is /dev/null, so `grep PAT >/dev/null` keeps the race.
+- **Apply**: producer out of the pipeline. Tests: `grep -q PAT < <(cmd)`. Prod: call inside the condition `if grep -q PAT <<<"$(cmd 2>&1)"` (a bare `out=$(cmd)` aborts under `set -e` when the function runs bare). `printf '%s' "$v" | grep -q` safe (builtin, one write). Same class: `| head -1`, awk `{print; exit}`. Not decidable by text census → structural fix, no `grep -q` lint rule. [[BDR-110]]
+
+## LRN-190 — Oracle hygiene: wrapped lines, baselines, no rm -rf via variable
+- **Context**: GATE 0 criterion 4 NOT-MET while code correct: executor wrapped `grep -q … \` + `<<<"$(…)"` at 80 cols (my own style rule), single-line regex missed it. Criterion 7 `shellcheck` bare would fail on pre-existing info notes outside Health Stack scope. Criterion 2 CHECK held `rm -rf "$d"` (destructive-tools rule), executor's copy refused by permission system.
+- **Apply**: join continuations first (`sed -e ':a' -e 'N' -e '$!ba' -e 's/\\\n[[:space:]]*/ /g'`); lint criteria compare counts against base ref (`git show base:file | shellcheck -`); planted fixtures cleaned with `rm -f file; rmdir dir`. Oracle edits after a red floor logged in CLARIFICATIONS as "oracle maintenance", criterion text never loosened. Extends [[LRN-188]].
