Joseph Doherty 5953685ffb Seed the canonical OT schemas content under 3yearplan/schemas/ as a temporary location until a dedicated schemas repo is created (Gitea push-to-create is disabled, the dedicated repo needs a manual UI step). Initial seed contributed by the OtOpcUa team to unblock the EquipmentClassRef integration timeline (lmxopcua decision #112) and to provide the future cross-team owner with a concrete starting point rather than a blank slate. Marked DRAFT throughout with prominent "ownership TBD" framing in README and CONTRIBUTING — the future owner team should treat this seed as a starting point and revise format / structure / naming as the open questions in README "Open Questions" get resolved. ...

Includes: README explaining purpose / scope / temporary-location framing / format decision, CONTRIBUTING.md with proposed workflow + per-class semver versioning policy + validation commands, format/equipment-class.schema.json defining the shape of a class template (classId, version, displayName, applicability, signals, alarms, optional stateModel), format/tag-definition.schema.json defining the shape of a single canonical signal (name, dataType, category, unit, isArray, accessLevel, writeIdempotent, isHistorized, scaling), format/uns-subtree.schema.json defining the shape of a per-site UNS subtree (enterprise + site + areas + lines), classes/fanuc-cnc.json as the worked pilot class with 16 signals + 3 alarms + suggested state-derivation notes (per OtOpcUa corrections doc D1), uns/example-warsaw-west.json as a worked UNS subtree example, docs/overview.md (what / why / lifecycle / what's NOT in this repo), docs/format-decisions.md (8 numbered decisions covering JSON Schema choice per corrections D2, per-class semver, additive-only minor bumps, _default placeholder reservation, signal-name vs UNS-segment regex distinction, stateModel-as-informational, no per-equipment overrides at this layer, applicability.drivers as OtOpcUa driver enumeration), docs/consumer-integration.md (how OtOpcUa / Redpanda / dbt each integrate). $id URLs in the JSON schemas resolve at the actual current path so validators don't 404.

Top-level README adds a row to the Component Detail Files table pointing to schemas/. Corrections doc B2 (schemas-repo dependencies) marked partially RESOLVED with the seed location and a list of what still needs the plan team or cross-team owner to decide (owner team naming, dedicated repo migration, format-decision ratification, FANUC CNC pilot confirmation, CI gate setup, Redpanda + dbt consumer integration plumbing).
