| 3 | +# Detects whether a PR changes the native fingerprint — i.e. whether merging |
| 4 | +# it would leave main un-OTA-able until a new store build ships. Native-change |
| 5 | +# PRs get the "📱 Native Change" label so they can be held and merged as a |
| 6 | +# batch right before the next store submission, keeping main OTA-able for |
| 7 | +# everything else in between. (Once one native PR merges, every later merge |
| 8 | +# inherits the drifted fingerprint and loses OTA reach too — that is why the |
| 9 | +# signal has to fire before merge, not after.) |
| 10 | +# |
| 11 | +# The check is advisory: it always passes, the label is the signal. Both |
| 12 | +# fingerprints are computed in this one job (same OS, same corepack-pinned |
| 13 | +# pnpm), so the comparison is self-consistent; no EXPO_TOKEN needed. |
