6The nine disciplinesthe practices that pass in every team that read themreads the disciplines and evidence registers

Organise

Structure3 of 90Nothing crossed either way.

Talent3 of 10+2was 1 of 10, 2027-05-04Two practices began passing, among them that every role whose entry-level work has been automated has a written progression path.

Finance7 of 11+3was 4 of 11, 2027-05-04Three practices began passing, among them that every customer release carries the token cost of producing it, recorded against the release rather than against the month.

Build

Architecture4 of 17+2was 2 of 17, 2027-05-04Two practices began passing, among them that every term crossing this boundary resolves to one agreed meaning, with an arbiter and one declared place where translation happens, and the agreed term is the one the published interface carries.

Engineering3 of 15+1was 2 of 15, 2027-05-04One practice began passing, the one asking that the construction is chosen deliberately between deterministic code, a single model call, an agent and an orchestration, with the simpler option tried or ruled out on the record.

Data4 of 11+3was 1 of 11, 2027-05-04Three practices began passing, among them that every source the use case touches, structured or not, has an identified owner, a quality gate that passes, lineage to origin, and a recorded basis on which it may be used for this purpose.

Assure

Risk5 of 11-1was 6 of 11, 2027-05-04One practice stopped passing, the one asking that every model this team runs is validated before it is used and after every material change, by somebody independent of the people who built and run it, as deeply and as often as the firm's model risk policy requires for its tier.

Security4 of 11+1was 3 of 11, 2027-05-04One practice began passing, the one asking that what an agent believes can be written only by identified writers, and what it retrieves has a stated provenance.

Ethics2 of 120was 2 of 12, 2027-05-04One practice began passing, the one asking that what was promised to the people whose work the machine changed is recorded against the role and reported against, and the people who never appear as claimants are looked for; One practice stopped passing, the one asking that every use case that reads personal data is screened for a data protection impact assessment before it first runs, and where one is owed it is completed, with the data protection officer's advice recorded, before that date.

The record states why beside each of them, and the funding panel prints its reason on the row.
