Second review cycle, security + checklist: - IMPECCABLE_BIN=/bin/sh (or node) was READY, and `detect` with cwd=repoRoot made the interpreter run the repository's own `detect` file. Every engine candidate (env override, PATH entry, cache, sibling) is now judged by the realpath of the FILE and must be named impeccable[.exe]; PATH and cache candidates that resolve into the repository are skipped like the others. "Inside the project" means the repository, or cwd when cwd is a project directory: HOME and its ancestors are exempt, so a URL-mode review launched from HOME still finds the HOME-rooted installs. - A base for --changed that starts with `-` was spliced into git argv (`--output=<file>` made git write a file and report no changes); an option- like or missing base is DETECT_REFUSED (not a ref name), exit 1, and the parser no longer defaults a missing value to main. - DOM dumps are the audited page's bytes, so an in-file `impeccable-disable` comment there is page-controlled: batches under the designs root run with --no-inline-ignores, repository batches keep the project's own ignores. - neutralizeSentinels covers the shapes it missed (bare sentinels such as DETECT_TOP total= and IMPECCABLE_DISABLED, the DETECT_EXIT_CODE= echo, the `[rule-id] impact=` group header) in one precompiled alternation instead of 37 replaceAll passes per field; only kept findings are normalized, and the summary's total stays the engine's count. - The minimal engine environment compares keys case-insensitively on Windows (process.env enumerates Path, SystemRoot there) and passes PATHEXT, COMSPEC, HOMEDRIVE, HOMEPATH, PROGRAMDATA. - Bare 64s move into DETECT_LIMITS; the unused SentinelName type is gone; the header states the directory-target contract (the engine's own walk). Tests: an interpreter as IMPECCABLE_BIN never runs the repo's detect file; a PATH symlink into the repository is never READY; option-like and empty bases are refused with no file written; the designs-root batch carries --no-inline-ignores and the repo batch does not; the identity label is deterministic per binary; the bare-sentinel and header shapes are neutralized; the installed fake engine works without IMPECCABLE_FAKE_OUTPUT (the helper copies the sample beside it); two tests clean up in finally.
