There are two kinds of history: the kind you can quote, and the kind that hides in routing slips.When a pristine archival box arrives at Halden University Special Collections, archivist Tessa Hart treats it like any other accession-photograph the seams, log the timestamps, protect the chain of custody. But the package is too clean, the instructions too confident, and the deed of gift strangely unfinished. Inside, a binder labeled NULL PROTOCOL lays out a continuity method for secret programs: how to keep development alive after scrutiny, how to reclassify activity into "instrumentation," how to preserve capability for insiders while producing ambiguity for everyone else.Then the archive itself moves before Tessa does. A pending accession generates a visitor request. A vendor service account edits fields from off-campus. A "sensitivity" flag appears as if it were law. When Tessa asks the simplest provenance questions-who is the donor, who is the custodian, who authorized the restrictions-she is offered "help," then warned not to become a compliance problem.Refusing to be routed, Tessa builds her own record: screenshots, physical ledgers, audit trails, and cross-indexes that link the box to older faculty files and a coastal range whose paperwork has survived by being boring. The deeper she follows the seams-missing carbons, procurement ghosts, telemetry summaries-the clearer the design becomes: not a single hidden object, but an infrastructure for making claims unrecoverable.NULL PROTOCOL is a procedural suspense novel about archives as battlegrounds, secrecy as workflow, and what it takes to force a system to name itself before it "forgets" you.
