Expand concept system: modes, ratings, re-roll, breadth strategy

Catalog: mode-aligned staging surfaces (persuade/operate/read/experience),
star ratings on approvals feeding challenger draw weights, family
retirements, authoring strategy and territory guide, rework and breadth
authoring rounds, composition mining from rejected worlds.

Seed: six challengers (two per tier), --reroll chains, --mode staging
filter, rating-weighted draws. New-work: Present/visualize/re-roll flow,
image-gen requirement, register-neutral vocabulary.

Pipeline: per-mode staging prompts with split frames, hero-from-board
reference generation, render-safety guards. Labs: ratings UI, unrated
filter, mode chips, composition approve-guard.

 ## Building
 
+### Developer Lab URLs
+
+No-index visual harnesses and internal inspectors live under `/labs/<subject>`. Use a short subject noun (`/labs/live-ui`, later `/labs/detector`), not a second `-lab` suffix. Stable public references such as `/docs` and `/design-system` stay top-level. Keep legacy top-level lab routes working through redirects when a lab moves; migrate existing exceptions when that surface is next changed rather than duplicating the page.

+# World catalog authoring guide
+
+How new concept-world rounds are authored, gated, and reviewed. Distilled from the full human sweep of 2026-07-20/21 (325 entries reviewed, 169 approved, all approved entries star-rated). The machine-readable core lives in `skill/scripts/concept-ingredients.json` under `qualityBar` (`rejectIf`, `authoringStrategy`); this guide carries the reasoning and the territory map.
+
+## The pipeline
+
+1. An authoring agent reads `qualityBar` (including `authoringStrategy`) and the review file. Three-star approvals are positive exemplars; rejection and rating notes are negative space.
+2. New entries merge as `pending`. Nothing ships without human review.
+3. The render gate runs before review: specimen board first, then the desktop hero generated with the board attached as binding reference (`scripts/generate-world-cards.mjs`; the images/edits path keeps both images one system).
+4. The reviewer decides in `/labs/worlds`: approve or reject, star ratings on approvals (3 exceptional, 2 solid, 1 marginal), notes on anything instructive. Ratings feed challenger draws in `concept-seed.mjs` (3-star doubles odds, 1-star sits out).
+
+## What wins
+
+The winner-property test. Every candidate must be:
+
+- **Born-designed**: the source is a produced 2D or display artifact with an existing graphic system, not a material, mood, or place. Even atmosphere-tier winners are secretly graphic (wax-print cloth, brick-build instructions, raku surface).
+- **Dense**: the tradition immediately yields palette, materials, a type voice, several component roles, and a signature state change.
+- **Era-and-school specific**: "1950s Blue Note session sleeve", never "record covers".
+- **New territory**: the peak artifact of a culture the catalog has not touched. Proven seams saturate fast: the 2026-07-21 depth round scored 3/12 with 0 flagships because second-tier artifacts from mined veins read as near-duplicates ("too similar to others we already have"). Breadth-first beats depth-first.
+- **System-distinct**: check the candidate against approved entries at the system level (palette plus type voice), not just by name. A different artifact with the same green-phosphor system is a duplicate.
+
+Flagship share by tier after the full sweep: graphic 52%, interaction 55%, atmosphere 29%. Interaction display languages stay overweighted; atmosphere qualifies only through the intrinsic-pattern rule in `rejectIf`.
+
+## What loses
+
+- Translation failures: the dominant rejection ("doesn't translate to interface"). Material worlds without an intrinsic 2D pattern system never recover, and re-authoring them fails again (rework hit rate ~33%, and only for taste fixes, never translation fixes).
+- Too narrow (single prop, single color), too abstract, operations archetypes, generic categories.
+- Render traps: brass or metal interface chrome reads cheap (skeuomorphism itself is fine; execution is the issue), non-Latin copy drift on non-Western worlds (interface copy stays English), AI-cliche motifs (Matrix glyph rain, recording dots), dated game chrome (game-born worlds are welcome at contemporary award standard), em dashes in rendered copy.
+
+## Cultural care
+
+Skip living sacred, ceremonial, or community-owned traditions without an established commercial graphic lineage; skip highly religious material outright. Traditions enter cleanly when they already have a commercial or civic design history the way adinkra printing, thangka-informed diagram craft, hanafuda (a published card game), or azulejo (civic architecture) do. When in doubt, leave it out.
+
+## Territory map (unmined as of 2026-07-21)
+
+One candidate per territory, always the territory's canonical peak:
+
+- **Print and publishing**: Penguin/Pelican Marber grid, ligne claire comics, fotonovela, children's book schools (Scarry, Golden Books), Victorian trade cards, stamp design, marbled endpapers.
+- **Technical and scientific illustration**: Haeckel plates, patent drawings, anatomical atlases, exploded-view manuals, Sanborn insurance maps, airline safety cards.
+- **Fashion as artifact** (not draping): tartan clan registries, kimono/obi pattern grammar, sewing-pattern envelopes with tissue markings, Take Ivy catalog photography, sneaker-box and colorway-naming culture, techwear spec labels.
+- **Games and decks**: tarot (commercial deck lineage), hanafuda, mahjong tiles, Tamiya model-kit box art with sprue diagrams, Game & Watch LCD language, casino chip and felt graphics.
+- **Global commercial traditions**: Portuguese azulejo, heraldry, sonidero/cumbia posters, Jamaican soundsystem graphics, Tropicália, Ethiopian commercial iconography, Mayan codex facsimile publishing.
+- **Fine-art movements with systems**: Vorticism, Precisionism, Le Corbusier polychromy, Barragan color walls.
+
+Mark territories off as rounds mine them; a mined territory moves to the saturation gate.
+
+## Round mechanics
+
+- Rounds stay small (~12) and are treated as experiments; expected hit rate is 25-40% now that the initial canonical harvest is done. Read the verdicts before the next round; every rejection note is calibration.
+- Standing reviewer requests: more non-Western systems, more cassette/VHS-era systems.
+- Retired families never receive new entries: machines-contraptions, food-potioncraft, memory-ruins, festivals-public-life.
