Two closed, substantive experiments were missing their DESIGN.md write-up despite being referenced as prior art by later sections: - 9o5/xi7/b3v (closed 2026-06-30/07-17): multi-use-leaf type superposition, a full feature build + real A/B validation (negative — OFF beats ON on both programme-house and harbor-house) + a veto-hatch follow-up for the one genuine false-positive interchange class found. §17 and §20 both cite its verdict directly but it never got its own section. - mi7 (closed 2026-07-25): 3D bubble-diagram / topological-hop-distance fitness signal prototype, tested against real evolved trajectories on two programmes, both formulations null. bubble.py was left in the tree uncommitted "as documented reference" by the closing session -- committing it now (with two trivial ruff fixes: unused import, ambiguous var name) so the reference this write-up makes to it is actually resolvable, plus a CLAUDE.md module-list entry. Numbered §26/§27 (appended, not inserted chronologically) to avoid renumbering every cross-reference in §14-§25. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>

This file provides instructions and context for AI coding agents working on this project.

## Beads Issue Tracker
|
|
|
|
This project uses **bd (beads)** for issue tracking. Run `bd prime` to see full workflow context and commands.
|
|
|
|
### Quick Reference
|
|
|
|
```bash
|
|
bd ready # Find available work
|
|
bd show <id> # View issue details
|
|
bd update <id> --claim # Claim work
|
|
bd close <id> # Complete work
|
|
```
|
|
|
|
### Rules
|
|
|
|
- Use `bd` for ALL task tracking — do NOT use TodoWrite, TaskCreate, or markdown TODO lists
|
|
- Run `bd prime` for detailed command reference and session close protocol
|
|
- Use `bd remember` for persistent knowledge — do NOT use MEMORY.md files
|
|
|
|
## Session Completion
|
|
|
|
**When ending a work session**, you MUST complete ALL steps below. Work is NOT complete until `git push` succeeds.
|
|
|
|
**MANDATORY WORKFLOW:**
|
|
|
|
1. **File issues for remaining work** - Create issues for anything that needs follow-up
|
|
2. **Run quality gates** (if code changed) - Tests, linters, builds
|
|
3. **Update issue status** - Close finished work, update in-progress items
|
|
4. **PUSH TO REMOTE** - This is MANDATORY:
|
|
```bash
|
|
git pull --rebase
|
|
bd dolt push
|
|
git push
|
|
git status # MUST show "up to date with origin"
|
|
```
|
|
5. **Clean up** - Clear stashes, prune remote branches
|
|
6. **Verify** - All changes committed AND pushed
|
|
7. **Hand off** - Provide context for next session
|
|
|
|
**CRITICAL RULES:**
|
|
- Work is NOT complete until `git push` succeeds
|
|
- NEVER stop before pushing - that leaves work stranded locally
|
|
- NEVER say "ready to push when you are" - YOU must push
|
|
- If push fails, resolve and retry until it succeeds

## Build & Test
|
|
|
|
```bash
|
|
pip install -e .
|
|
pytest
|
|
```
|
|
|
|
## Architecture Overview
|
|
|
|
homemaker-layout is a Python successor to the Perl [Urb](../urb) project. It
|
|
represents a building as a binary slicing tree where leaves carry **target
|
|
dimensions** from the programme and division ratios are **solved bottom-up**
|
|
(inverting Urb's top-down approach). The evolutionary search explores topology,
|
|
types, and adjacency only.
|
|
|
|
Key modules:
|
|
- `dom.py` — read/write Urb `.dom` YAML into a `Node` tree
|
|
- `geometry.py` — faithful port of Urb's top-down geometry
|
|
- `programme.py` — parse `patterns.config` space requirements
|
|
- `solver.py` — bottom-up ratio solve (scipy)
|
|
- `fitness.py` — native Python fitness evaluator (replaces Perl oracle)
|
|
- `fitness_cmd.py` — `homemaker-fitness` CLI entry point
|
|
- `collapse_cmd.py` — `homemaker-collapse` CLI: finish-time global cell→room collapse (94g)
|
|
- `graph.py` — leaf-adjacency graph for programme-driven fitness checks
|
|
- `genome.py` — topology genome: base-floor tree + per-storey deltas
|
|
- `operators.py` — high-locality mutation and subtree crossover
|
|
- `innerloop.py` — ratio optimisation inner loop (Nelder-Mead / CMA-ES)
|
|
- `driver.py` — memetic search outer loop
|
|
- `evolve.py` — `homemaker-evolve` CLI entry point
|
|
- `oracle.py` — legacy Perl shim, kept for validation only; do not use in new code
|
|
- `bubble.py` — 3D bubble-diagram adjacency fitness-signal prototype (DESIGN.md §27, `mi7`); validated NULL, not wired into `fitness.py` — reference only, do not build on without a new formulation
|
|
|
|
## Conventions & Patterns
|
|
|
|
### Scoring .dom files
|
|
|
|
Use the native `homemaker-fitness` command. Like the old `urb-fitness.pl`, you
|
|
**must `cd` to the directory containing the `.dom` file first** — the tool
|
|
resolves `patterns.config`, `costs.config`, and writes `.score`/`.fails`
|
|
relative to `cwd`:
|
|
|
|
```bash
|
|
cd /home/bruno/src/homemaker-layout/examples/programme-house
|
|
homemaker-fitness cf0b8a77e8b2325f92a7e7d150184a55.dom
|
|
```
|
|
|
|
The score is written to `<file>.dom.score` and failures to `<file>.dom.fails`; the numeric score is also printed to stderr.
|
|
|
|
Do **not** use `urb-fitness.pl` directly — `oracle.py` and the Perl tool are
|
|
kept only for cross-validation.
