Phase 1 Data Model: Unify charter activation surfaces

No persistent DB. Four YAML surfaces + their relationships.

Surface: Activation ledger (AUTHORITY)

  • File: .kittify/config.yaml → activated_directives / activated_tactics / activated_procedures / activated_paradigms / activated_styleguides / activated_toolguides (per-kind lists of config-stems).
  • Role: THE single activation authority (FR-001). Written only via charter.activation_engine.commit_plan.
  • Read by: PackContext.from_config (runtime, today) AND — after this mission — the derivation (compiler/synthesizer).

Surface: Interview record

  • File: .kittify/charter/interview/answers.yaml → selected_directives etc.
  • Role after this mission: captured interview selections only (FR-003). NOT an activation source. Its selections are promoted into the activation ledger (FR-007).

Surface: Compiled reference set (DERIVED)

  • File: .kittify/charter/references.yaml.
  • Role: derived from the activation ledger (was: from the interview record). The resolution surface the dangler test checks.

Surface: DRG graph (DERIVED)

  • File: src/doctrine/graph.yaml (built-in) + induced charter graph.
  • Role: derived; must stay byte-fresh (deterministic generate_graph).

Invariants

  • I-1 (parity): every entry in the activation ledger resolves in the compiled reference set, and nothing resolves that is absent from the ledger. Enforced fail-closed by consistency_check (FR-005).
  • I-2 (answers inert): editing the interview record without an activation-ledger change has no effect on the compiled reference set (SC-004).
  • I-3 (migration lossless): the ledger is the migration seed; 0 previously-active artefacts dropped (FR-006); answers-only artefacts are promoted, not dropped.

Derivation flow (target)

interview -> answers.yaml (record)
          -> promote selections -> config.activated_*  (AUTHORITY, FR-007)
charter activate/deactivate     -> config.activated_*  (commit_plan)
config.activated_* --derive-->  references.yaml + graph.yaml
consistency_check: config == references == graph  (fail-closed, FR-005)
