Aaron: "backlog is uml modeling useful for the factory and what tools would it require us map?" Filed as P3 row with two-question research pointer (utility vs existing OpenSpec + formal-spec discipline; tooling-map for factory-technology-inventory). First-pass recommendation: Mermaid as factory-aligned default (git-native, zero toolchain). Auto-merge armed. Adjacent to Rational Rose P3 row (PR #163) — both will sit together on merge; row #54 first firing likely flags for consolidation consideration.

Pull request overview
Adds a new P3 BACKLOG entry to capture a research question about whether UML modelling is useful for the factory and, if so, which tooling would need to be inventoried alongside the existing spec/formal-verification stack.
Changes:
- Add a new P3 backlog bullet describing the UML utility question and a tooling-map question.
- Include an initial (non-binding) recommendation comparing Mermaid, PlantUML, Structurizr, and heavier UML tools.
- Add cross-references to related planned inventory/docs work and adjacent backlog items.
Aaron 2026-04-23: "backlog is uml modeling useful for the factory and what tools would it require us map?" Two-question research pointer: 1. Utility — does UML add value on top of OpenSpec + formal specs (TLA+ / Lean / Z3 / FsCheck / Alloy)? 2. Tooling-map — if we adopt, what tools would the factory inventory (PlantUML / Mermaid / draw.io / Structurizr / Rational Rose lineage)? Composes with: - Rational Rose P3 row (adjacent when PR #163 merges) - docs/FACTORY-TECHNOLOGY-INVENTORY.md (PR #170 target) - OpenSpec workflow (spec-as-source-of-truth already in place) - Formal-spec stack First-pass recommendation (to validate): Mermaid is the factory-aligned default (git-native, zero toolchain, GitHub renders natively); heavy UML tools likely over-scoped. Research note under docs/research/uml-modelling-for-the- factory-YYYY-MM-DD.md when prioritised. No adopt commitment. No deadline. Effort S first-pass; M if adopting.

…lassification BACKLOG 13 session PRs merged. Three landed in ~4 minutes: #159 (Overlay A #3), #172 (Pages-UI BACKLOG), #173 (UML BACKLOG). PR #173 unblock: 4 findings — Rational Rose cross-ref stale after rebase (row now adjacent on main); grammar nit fixed; row-number accepted as current; hard-coded row #49 kept. 4 threads resolved. Aaron directive (two-message): age-classification skill covering language + concepts. Filed PR #176 as P3 row, captures both axes + bi-audience (AI + humans) + human- standards-mapping + new physiology-based factory standard. Auto-merge armed. Rational Rose + UML rows now adjacent on main — prime target for row #54 first-fire overlap sweep. Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>
