REVIEW: GREEN PARTIALAssertion quality: strong — the non-destructive contract is now asserted against the live code path rather than the docstring that promised it
Score: — no behavioural scorePARTIAL — PARTS.md built = 'script yes — never run live' — a behavioural score would overstate what actually runs (spec-conformance only: 4.0/4 — not comparable to a built part, never averaged)
variant: non-destructive-contract-in-codebuilt: script yes — never run live

coachPASS · the dry-run branch exists in live code, not only in the usage docstring
coachPASS · live code READS the existing tab before writing (the non-destructive claim)
NOT FOUND — the 'never overwrites marks' promise lives only in prose; nothing in the code reads existing values before writing
coachPASS · live code has an append/skip-existing path rather than a blanket overwrite
NOT FOUND — the idempotency contract is unenforced in code
