+# Census approval: wake-latency-4

+Ruling `census-ruling-wake-latency-4`. Every change below keeps the disposition it already has, so it needs an approval, not a decision.

+Envelopes re-pinned: `internal/instancectl`, `internal/release`.

+Seal: `86570d1326baad6d866b4066b6bf65218434b201fb1f2c05ebc6e3c79f9c5a98` → `86570d1326baad6d866b4066b6bf65218434b201fb1f2c05ebc6e3c79f9c5a98`.

+Overlay: `internal/provision/testdata/plan14-root-reads-wake-latency-4.tsv`, appended to `internal/provision/testdata/plan14-root-reads-chain.tsv`.

+## The decision: two new units, written by hand

+`internal/release/digestcache.go` adds two units that read files, so census-propose leaves them to a decision. Their rows are in `internal/provision/testdata/plan14-root-reads-wake-latency-4-new.tsv`, chained before the overlay above. The seal does not move.

+| unit | reads | proposed disposition |

+|---|---|---|

+| `FileSHA256Cached` | `file:Open`: opens the staged build it is asked about, as `FileSHA256` does | `authority`, B3,J4, `root-input;kept=B3;scope=protected-decision-only`, the same as `FileSHA256` |

+| `SHA256Cached` | `file:Stat` ×2: fstats the descriptor the caller opened, before and after hashing it | the same |

+The callers are the same as `FileSHA256`'s: the agent's `VerifyStaged`, and root instance control's staged-exe check, which opens the file beneath the version store without following a symlink. What changes is that the digest is reused for an unchanged file identity: device, inode, size, mtime and ctime. A file changed in the last two seconds, or while it was being hashed, is never cached.
