What

check:proto-reads fails on main 580c277358:

• unlisted hit at packages/core/src/variant.ts:36 (? PROTOCOLS[model.package])
• stale allowlist entry at script/check-proto-reads.allowlist.txt:50 (the pre-fix(core): read Variant PROTOCOLS table with an own-property guard #878 single-line form)

PR #878 replaced the single-line read with a multiline Object.hasOwn guard, so the sweep pattern (and therefore the allowlist line) no longer matches. This points the entry at the current hit line with the same disposition family: guarded: Object.hasOwn ternary at the same site (#862).

No source change to variant.ts.

Verification

• bun run check:proto-reads — before: 1 unlisted + 1 stale, exit 1; after: "All 45 prototype-chain read candidates ... dispositioned", exit 0
• bun run check:proto-reads on origin/main reproduced the report, so this was not pre-existing unrelated drift

Closes #896
