Bastien Chanot 42fc2e6acb job4: SPEC-03 curated-config-guard
New lib/tests/curated-config-guard.test.sh (+4 assertions). Extracts
restore_curated_configs() from install-plugins.sh AT TEST RUNTIME via
awk '/^restore_curated_configs\(\) \{/,\/^\}/' (verified single-
occurrence, column-0 closing brace) so drift in the real script
propagates into the test instead of testing a frozen copy. Harness
defines GUARDED_CONFIGS/CFG_SNAPSHOT/REPO/info() itself (the array
literal at install-plugins.sh:41 is outside the extracted range).
Sandbox REPO with the 3 fake guarded files + a pre-populated
CFG_SNAPSHOT; mutates CLAUDE.md only (simulated installer drift);
asserts: mutated file restored byte-identical (cmp -s), the other two
guarded files' content unchanged (not touched by the restore loop),
snapshot dir removed. Closes J4-03 (CRITICAL): the guard against
graphify's installer clobbering CLAUDE.md/settings.json had zero test
coverage.

Mutation (copy of install-plugins.sh, lean scratch — only that one
file, not the whole repo/.git): inverted the cmp condition
(`! cmp -s` → `cmp -s`) at the line the report names. RED: T1 fails
(the mutated file no longer gets restored — the inverted condition
only copies when already identical, a no-op, and skips restoration
exactly when it's needed). T2/T3/T4 stay green, confirming the
mutation is localized to the restore path.
GREEN: real repo unmutated, PASS=4 FAIL=0, shellcheck clean.
