Establishes the framework's foundation as a multi-site adoptable platform. ADRs (migrations/adr/): - ADR-001 (ACCEPTED): Asset is the platform contract; Machine retires. Three relationship types (partof, controls, connectedto) with free-text label, position-resolution chain (asset > related > location), hierarchical locations, sibling-bay propagation. - ADR-002 (ACCEPTED): Plugin contract semver via __contract_version__. - ADR-003 (ACCEPTED): Hybrid plugin distribution (in-tree bundled + filesystem-based external). - ADR-004 (ACCEPTED): Per-site instances, not multi-tenant. - ADR-005 (ACCEPTED): Equipment plugin (manufacturing) split from measuringtools plugin (metrology). Subtype-table pattern for protocol data (FOCAS, CLM, MTConnect). - ADR-006 (ACCEPTED): Plugin collector contract via get_collector_schema hook with API-key auth and identity-based upsert. Naming convention v1 (CONTRIBUTING.md): - DB tables/columns: lowercase concatenated, no underscores or dashes - DB-mirrored Python/JS variables match column names exactly; pure code follows host-language convention (PEP 8 / camelCase) - Closed acronym allowlist (universal + shop-floor domain), banned shorthand list with suffix exception (printers_bp etc allowed) - Plain ASCII everywhere: chat, docs, comments, string literals Style enforcement (scripts/check-naming-and-style.sh): - Pre-commit-runnable check script: non-ASCII, banned shorthand, snake_case DB names, snake_case API params in frontend - Fixes 14 violations across 11 files (Unicode arrows, snake_case params, ctx -> canvasContext, res -> response, req -> request_obj) Project state (CLAUDE.md, README.md, frontend/CLAUDE.md): - De-staled CLAUDE.md to reflect actual current state - README unifies DB story (MySQL canonical, SQLite test-only) - frontend/CLAUDE.md points at root convention Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

Architecture Decision Records
Each ADR captures a single architectural decision: the context, the decision itself, the consequences, and the alternatives considered. ADRs are immutable once accepted. Superseded ADRs stay in this folder with a pointer to the newer ADR.
Status definitions
- PROPOSED: drafted, awaiting decision
- ACCEPTED: decision is in effect
- SUPERSEDED: replaced by a later ADR (link forward)
- DEPRECATED: no longer in effect, no replacement

Authoring
When proposing a new decision, copy the most recent ADR as a template, increment the number, and update this index. Do not edit accepted ADRs in place; supersede them with a new one.
