What value does DHF create—and what proves it?
DHF is useful only when its controls improve delivery outcomes and those outcomes can be checked. This library connects customer value to evidence maturity, framework evolution, real cases, and explicit boundaries.
Value first, controls second
Quality, risk control, speed, continuity, and traceability are the outcomes. SAFE and TRUST explain how governed state changes contribute to them.
Every claim has a ceiling
A lower level cannot prove a higher one. A test does not prove runtime activation; publication does not prove production enforcement or customer outcomes.
- 01Design intentRequirements, ADRs, and documented contracts.
- 02Source implementedRepository code or content exists.
- 03Verification passedFresh checks support the current artifact.
- 04Runtime activeThe intended runtime matches and is operating.
- 05Publicly publishedThe public surface is deployed and read back.
- 06Production enforcedProduction controls are proven active.
- 07Customer outcome validatedObserved customer results support the value claim.
Show how capability matures
Evolution is meaningful when each stage names the customer problem, added control, and evidence required to claim the stage.
Make the protection inspectable
Control evidence explains what stops unsafe promotion, what records actual results, and what supports recovery.
Move from explanation to inspectable cases
Cases separate the claim, action, observed evidence, and boundary so a compelling story does not exceed what happened.
Failure handling is part of the proof
A credible delivery system preserves the failed receipt, restores known state, reads back independently, and requires fresh authority before retry.
Evidence is durable; status is dated
This library explains what different proof can support. The Status page remains the source for the current source, runtime, publication, and enforcement snapshot.
