Scope: Makeup Tool Cleansers, Palettes, Cases & Mirrors (supplies > personal > makeup_tool_cleansers) — the accessories around makeup brushes/sponges, not the brushes/sponges themselves (those are the sibling leaf makeup-brushes). Bundles four product types: brush/sponge cleansers, mixing palettes, brush cases/organizers, and makeup mirrors. One register, split by product_type, each type gets its own facet set.

Seed:
1. Olive-oil's harvest_date -> months_since_harvest parallels a mixing palette's stated dimensions -> derived mixing_surface_area (two sourced numbers, one divide/multiply, no extra fetch).
2. The dermatologist persona notices the cleanser's active agent (alcohol/solvent vs surfactant/soap) first, not scent or brand — confirms cleaning_agent_type as the expert facet and keeps fragrance/scent out as noise.

Branches:
- product_type -> cleanser/palette/case/mirror: four unrelated spec sets (chemistry, material, construction, optics); confirmed by crc_cleansers, crc_palettes, crc_cases, simplehuman_mirror all treating them as separate catalog categories.
- cleanser_format=spray -> rinse_requirement mostly moot: bennye_cleaner spray is explicitly wipe-dry, no-rinse ("quickly dissolving... convenient spray").
- mirror_lighting=unlit -> light_color_temperature/power_source/electrical_safety_mark moot: those facets only exist because simplehuman_mirror and fancii_mira2 describe lighted models; a plain mirror has none of them.

Noise (spec-sheet rows seen, left out):
- Scent/fragrance variants (Tropical Lemon, Guava Fig, Lavender Basil on crc_cleansers) — marketing preference, not an expert axis.
- Bottle/tin/jar size in oz/ml (2oz, 8oz, 16oz, 32oz, 125ml, 250ml) — packaging size, not a quality facet; format (solid/liquid/spray/wipe) already captures the functional difference.
- Mirror body color/finish (Brass, Black, White, Pink, Chrome on fancii_catalog) — cosmetic variant, not expertise.
- "Automatic Flip"/sensor-activated lighting (simplehuman_mirror) — single-brand convenience feature, not corroborated by a second source, left out of the register.
- Color-cosmetics "palette" (eyeshadow/foundation palettes like Ben Nye Lumiere Creme 18-Color Palette, Blend Bunny Eyeshadow Palette on crc_palettes) — these are the makeup product itself, not the mixing-tool palette this leaf covers; excluded to avoid scope creep onto the color-cosmetics leaf.
- Price and brand/vendor name across every source — never facets per house rule.
- Brightness in lux (simplehuman: "Brightness Lux: 100-800 Lux") — single-sourced spec, no second brand sheet states a comparable lux figure; left out per the two-source rule for numeric facets rather than added with an invented range.

Corrections (2026-10-26):
- Relabeled mirror_lighting, magnification_level, light_color_temperature, power_source, mount_type from source:listing to source:researched (backfill_cost kept/set to low, listing_field_hint reworded to say "brand spec page, not confirmed on third-party retail listings") — all five were cited only to simplehuman.com/fancii.com, never an independent retailer.
- Added facet battery_charge_duration (kind: text, researched, evidence simplehuman_mirror + fancii_mira2) capturing "1 Charge Lasts 5 Weeks" vs "up to 13 hours per charge" as the brand's own stated unit, with no invented weeks-to-hours conversion; wired into mirror_lighting's lighted/unlit branches and the three non-mirror product_type branches' makes_irrelevant lists.
- Added "both" to power_source's values (simplehuman's own spec table lists the mirror as Plug-In AND USB-C), updated cold_start_question and backfill_note to match.
- Reworded palette_size's backfill_note to flag the <4in/~5-6in/>6in cutoffs as an uncited heuristic rather than presenting them as a sourced mapping; removed the cutoffs from listing_field_hint.
- Rejected the cleanser container-size fix (check.md required fix 4): notes.md's existing "Noise" list already excludes bottle/tin/jar oz/ml size ("packaging size, not a quality facet; format already captures the functional difference") before this check ran — the checker's claim that no Noise justification exists for cleanser size is incorrect, so no facet or note was added.
- Added a Noise line for mirror brightness/lux (check.md required fix 6): single-sourced to simplehuman only, so per the two-source rule it is named under Noise instead of becoming a facet.
