MIN_CC_VERSION = '2.1.148'
LATEST_KNOWN_CC = '2.1.162' (new — 1 line/cycle, not 5 rows)
compareCCVersions()

that's the entire surface anything read.

🔬 Why it's safe (the consumers, read not grepped)

consumer	what it needed	verdict
`cc-version-check.ts:42`	iterated the matrix only for the MAX version (a scalar)	→ now reads `LATEST_KNOWN_CC`
`generate-docs-data.js`	regex-extracts `MIN_CC_VERSION` (a scalar)	unaffected
`stamp-cc-support.mjs`	`MIN_CC_VERSION`	unaffected
`hasFeature` + friends	called ONLY by tests (0 production)	removed
`cc-file-adoption-issues.sh`	grep said "consumer" — reads `cc-adoption-gaps.json`, NOT the matrix	never a consumer

✅ Verification

Full hooks suite 8502 passed, 0 failed · Biome + tsc clean · bundle 799→722 KB · rewrote the matrix test (10 pass) — covers the 2 constants + comparator; dropped the catalogue/helper tests with the code they tested.

📦 What lands

The cc-watch "catalogue in matrix" ritual is gone — bump LATEST_KNOWN_CC one line per adoption cycle instead of appending ~5 rows. Refs #2217 (the re-audit that confirmed this) · rule: shared/rules/cc-native-first.md
