# Architecture Decision Records (ADRs)

Canonical directory for all ADRs.

All current ADR links should target this directory as `docs/adr/...`.
`docs/decisions/...` was the historical path and must not be used for new
references.

Runtime execution contracts live in `docs/specs/runtime_contracts.md`; ADRs
may cite that spec when a decision adds or changes a runtime invariant.

## Master Blueprint ADR mapping (2026-07-20)

The Master Architectural Specification lists ADR-0240–0253 with titles that
**collide by number** with Accepted repository ADRs (especially 0246–0252).

- **Do not renumber or overwrite Accepted ADRs.**
- Authoritative reconciliation:  
  [`MASTER-BLUEPRINT-2026-07-20-ADR-MAPPING.md`](./MASTER-BLUEPRINT-2026-07-20-ADR-MAPPING.md)
- Governance freeze decision:  
  [`ADR-0253-master-blueprint-adr-collision-and-dual-pack-boundary.md`](./ADR-0253-master-blueprint-adr-collision-and-dual-pack-boundary.md)

## Binding non-ADR notes in this directory

- [`epistemic-taxonomy-ownership-stage3.md`](./epistemic-taxonomy-ownership-stage3.md)
  — binding ownership note (Master Blueprint Stage 3A, 2026-07-20): the three
  orthogonal epistemic axes (`EpistemicStatus` / `EpistemicState` /
  `GeometricCoherenceVerdict`) must not be collapsed into one enum.
