1Evidence spine
Running todayEvery record is hash-chained and bitemporal, with Merkle inclusion proofs, RFC 3161 timestamps and a chain of custody. Domain-agnostic by design: it knows records, hashes, times and authorities — not barracks.
What it does, and whether it runs today.
We do not replace the system of record. We prove it.
Barracks Ledger sits above whatever housing system a service already runs and holds what none of them was built to hold: the statutory obligation, the evidence that satisfies it, and a verifiable record of who knew what, and when. Each capability below carries one of three plain labels, and the label is the claim.
Running today on real, cited, public data. Schema complete built and tested, waiting on a sponsor's records. Designed specified, not running.
The seven primitives
2Compliance clock registry
Running todayEvery statutory and regulatory obligation is a first-class object: authority, obligation text, owner, due date, status, evidence slot, recurrence rule. The registry is data, not code. It holds 20 obligations; 17 are verified against the primary text, and the other three say why they are not.
3Occupancy reconciliation and ghost-occupancy detection
Running today on public and synthetic dataPersonnel records against room assignments, classified against 15 ghost-occupancy vectors — the statutory term of art, enumerated — with write-time prevention controls beside the detectors. It implements FY2026 NDAA § 2832(a)(2)(G). Two vectors have no detector yet, and each names the feed it waits on. Production use requires a sponsor's data.
4Inspection ledger
Schema complete · runs on sponsor dataInspector identity, state credential and expiry, an independence attestation, findings typed against the UFC 4-721-01 parameter table, photographs, chain of custody and a dispute process.
5Work-order lifecycle
Schema complete · runs on sponsor dataTiered clocks against the binding standard, UFC 4-721-01: emergency — respond within 1 hour, resolve within 24 hours; urgent — acknowledge within 8 hours, resolve within 7 days; routine — acknowledge within 24 hours, resolve within 30 days. Plus first-time-fix rate, reopen rate, saturation and closure verification.
6Waiver registry
Schema completeWaivers that are bounded, dated, countable, expiring and reportable to Congress — including the statutory limit in 10 U.S.C. § 2856a, under which a waiver terminates 15 months after it was issued.
7Award and contract analytics
Extract and classifier running today Views and pattern detection designedAn 881-row keyword extract of USAspending awards whose description names a specific building number (keyword barracks, award types A–D, FY2016–FY2026, retrieved 16 Sep 2026, walked to exhaustion by fiscal quarter), classified row by row: 215 permanent-party unaccompanied housing, 579 place-name only, the rest training, academy, family housing, support services or not housing at all.
It is an extract, not a corpus, and nothing sums it. The classifier's job is to say which rows are barracks; a dollar total over a keyword match would be the error this screen was built to stop. Per-installation and per-vendor views and the bridge-contract and ceiling-increase pattern detection are designed, not running.
7aShow the Work
Running today on public dataThe Department's stated barracks commitments — money, action, reporting — quoted verbatim, official and press sources kept apart, each with what would prove it and who holds that record, beside the 21 items the Barracks Task Force page itself lists. Built 23 September 2026 on public data. Of the 8 commitments on the screen, 7 read not in a public record; the eighth, a Marine Corps task order in the Department's contract announcement of 6 July 2026, reads contract action in a public record. That is the demonstration: the public record cannot yet show most of the work, and the screen says so without inferring that the work was not done.
Also built, and required by nothing
- An inspector independence graph computed from public filings and corporate records, rather than asserted by the inspector.
- Five-clock deconfliction across the fire, safety, habitability, historic and real-property inspection regimes.
- A bitemporal time machine: show this installation as the housing office understood it on the day the inspection was signed.
- A swing-space displacement planner for the mass-relocation events that destroy occupancy registers.
What is real today, stated plainly
In open-data mode, Barracks Ledger is a compliance and evidence shell. It knows the obligations, the deadlines, the awards that name a building and the installations. It knows nothing about any room: there is no public list of Real Property Unique Identifiers, so the primary key of this domain cannot be populated from open data.
The moment a sponsor connects one installation, the same shell becomes an operations tool. We do not sell it as an operations tool before that.
Both frames, side by side
The statutory frame
§ 2832, § 2831, the clocks, the ten elements, and Submission Review — the plan due 30 September 2026, read element by element when it is submitted.
The show-the-work frame
The Barracks Task Force and the Secretary's monthly report “to confirm work is getting accomplished,” as reported by Stars and Stripes — each commitment beside the record that would prove it.
