DHF Operating Memory · English

BEST sees the system. CARE guides action. RECOVER contains incidents.

This page is a memory and recovery aid, not the site hub. BEST and CARE help teams retell DHF business concerns, controls, value, and evolution. RECOVER unfolds only after an external write or structural failure. Value claims and evidence levels belong to the Evidence page.

01 · Two lenses

Same system, different emphasis

BEST explains the system to decision makers. CARE helps practitioners remember what to protect during daily work.

BEST · system view

  • B — Business concerns: CAP names continuity, accuracy, and permission.
  • E — Evolution: BRIDGE describes maturity from Baseline to Enforcement.
  • S — Safe transitions: SAFE governs each state change.
  • T — Trusted outcomes: TRUST names the value domains.

CARE · action view

  • C — Concerns: identify what the business cannot lose.
  • A — Assurance: add boundaries, authority, facts, and recovery.
  • R — Reliability: turn controlled action into checkable outcomes.
  • E — Evolution: preserve the reliable practice and mature it.
02 · Base vocabulary

The mnemonics do not replace the concepts

BEST and CARE say how to remember. CAP, BRIDGE, SAFE, and TRUST say what the system protects and why.

CAP

Continuity, Accuracy, and Permission define the business concerns.

BRIDGE

Baseline, Receipts, Inspection, Decoupling, Grading, and Enforcement describe evolution.

SAFE

Specification, Authorization, Facts, and Error-recovery govern transitions.

TRUST

Quality, risk control, speed, continuity, and traceability express value.

03 · Incident response

RECOVER starts only after failure

Recovery preserves the failed receipt, restores known state, reads back independently, and refuses to treat recovered context as renewed permission.

  1. RRecognize the partial or uncertain outcome.
  2. EEnd further mutation.
  3. CCapture the failed receipt and scope.
  4. OObtain the last trusted state.
  5. VVerify restoration independently.
  6. EEscalate for fresh authority.
  7. RResume only from proven state.
Boundary: recovery evidence can restore facts and continuity. It cannot silently grant a connector retry, production write, publication, or destructive action.
04 · Model taxonomy

Choose the concept by the question

These terms have distinct jobs. They are not competing workflows.

05 · Reading path

Start with evolution and value, then inspect cases and recovery evidence.
