writeState() drops its private tmp+writeFileSync+rename copy (no fsync,
Date.now() tmp names, best-effort chmod) and delegates to
src/utils/atomic-write.js atomicWriteJSON (exclusive-create tmp, fsync,
rename, parent-dir fsync, 0600). A torn stripe-fulfillments.json could
previously make a webhook retry mint a SECOND valid license key for an
order that already has one. Both consumers (routes/billing.js,
scripts/stripe-license-bridge.js) JSON.parse only - trailing-newline
drop in the canonical serializer is harmless. Unused crypto require
removed. +2 DC-103 pins: full lifecycle 0600/complete/zero-leftovers,
and dual-instance interleaved writes (bridge+API file-IPC) with no tmp
collisions. 121 suites / 2776 tests green.
Judge: GLM-5.3 round-1 A (deleg_bd49a97b), URN urn:ump:layk7h326sqymcsh6tiusrs2sdbqdcx6ygvcuwwoxqn4rf7ycoua
Drops share-store's private _atomicWriteJSON copy (pid+Date.now() tmp
names, no fsync, no failure cleanup) in favor of src/utils/atomic-write.js:
fsync'd same-dir tmp+rename, exclusive-create 0600, parent-dir fsync,
cleanup-on-failure. Also fixes a latent bug in the same file: .share-secret
signing-key persistence used plain fs.writeFileSync — a torn write would
silently rotate the HMAC key on next boot, invalidating every outstanding
share signature (links 404, no error logged). Now atomicWriteFile.
Sole consumers parse JSON / trim(), so the dropped trailing newline on
shares.json is unobservable. +2 regression tests pin 0600 on both files,
complete content, zero tmp leftovers, and HMAC-still-verifies via getRaw.
Judge: GLM-5.3 cold read, round-1 A, deleg_50d5c239 (41s, 4 calls).

Drops invite-store's private _atomicWriteJSON copy (pid+Date.now() tmp
names, no fsync, no failure cleanup) in favor of src/utils/atomic-write.js:
fsync'd same-dir tmp+rename, exclusive-create 0600, parent-dir fsync,
cleanup-on-failure. Sole format consumer is a JSON.parse reader, so the
dropped trailing newline is unobservable. +2 store-level regression tests
pin 0600 / complete JSON / no temp leftovers under burst mutations.
Judge: GLM-5.3 cold read, round-1 A, deleg_7177d506.
