[D_056 gate] Independent CAD source adapters: ODB++, IPC-2581, Gerber, KiCad #532
Description
Parent: #520. The Canonical data model can express arbitrary layer/via spans; this does NOT mean those native formats currently import.
Implement: source-specific adapters per native format (split into child PRs to control risk) with documented tokens/containers, physical layer mapping, Stackup/Net/Track/Padstack/Via/Copper/Part/Drill and provenance. Gerber+drill lacks guaranteed net/stackup and must expose partial/unknown rather than synthesizing proof. Preserve source-vs-canonical identities and explicit unknown with fail-closed diagnostics.
Acceptance per format: authoritative format specs, licensed/public synthetic fixtures and source mutation/negative tests, cross-format same-board canonical geometry comparisons with independent oracle, no invented connected layers or SI, verified CI/native platform tests, dedicated documentation and source-compatible versioning. Mark each adapter separately qualified, not universal by default.

D_056_08 status correction (2026-11-10 KST): This multi-format adapter gate was closed at 2026-11-10T01:09:41Z concurrently with merging the limited ODB++ code PR #562, although its acceptance criteria explicitly cover ODB++, IPC-2581, Gerber and KiCad. The closure does not establish those native adapters or cross-format oracle tests. Reopened to preserve the actual #532 acceptance gate.
