Scope: Game Tables (supplies > active > game_tables) — recreation tables bought as furniture: pool/billiards, table tennis, foosball, air hockey, shuffleboard, and multi-game combo tables. Split by game_type, each type gets its own facet set.

Seed: 1) Equivalent of "weave vs thread count" here is bed/deck material vs size: size (7ft/8ft/9ft, "8-foot") is the number every listing leads with, but slate-vs-MDF, honeycomb-core-vs-particleboard, and ITTF-wood-vs-laminate are what actually decide how the table plays and ages. 2) A sommelier (origin/process/aging) would notice first how each surface ages, not its day-one spec: thin home slate can still seam-warp over years, honeycomb air decks delaminate, table-tennis laminate yellows and loses bounce, and baize wears bald along the kitchen line long before the frame fails.

Noise (spec-sheet rows seen but not made facets): carom-billiards K-55 cushion profile — out of scope, not a pocket-billiards/pool-table product; cue/ball weight and dimensions — accessory, not the table; miniature/novelty tabletop pool (1x1.6ft) — toy-scale outlier, not the furniture leaf; net-post clamp type for table tennis — too minor, no sourced distinction found; air hockey mallet/puck color (yellow/red/green) — cosmetic, not a buying decision; foosball ball material (wood/cork/plastic/marble) — real but minor vs figure material, folded into figure_material's note instead of a separate facet; price, brand, rating — excluded per rule; pool cabinet finish/wood species (olhausenbilliards.com markets "size, finish, felt color" together) — cosmetic/furniture-matching rather than performance, and no second source for a value list was found this run, so excluded rather than guessed.

Corrections: Dropped a planned foosball_rod_type (telescoping vs non-telescoping) safety facet — could not find any fetched source (Wikipedia Table_football article, CPSC pages, and brand/retailer buying guides all returned no content or were blocked/403/DNS-failed) confirming rod-type safety language, so it was cut rather than invented. Dropped a planned tt_tabletop_thickness (mm) numeric facet for the same reason — no second source for specific mm thresholds. WebSearch was exhausted this session (200/200 used before this run); all research is curl fetches of Wikipedia (which rendered cleanly) plus unsuccessful attempts at brand/retailer/standards-body pages (familyleisure.com 403, astm.org 403, valley-dynamo.com 403, usairhockey.org DNS failure, joola.com/stiga.com 404, imperialusa.com/gameroomguys.com returned JS-shell pages with no extractable text).

Corrections (2026-10-26): Removed pool_table_size value 7_5ft and its reference's "7/7.5/8/8.5/9ft" supports line — the cited Wikipedia billiard_table article lists only 7/8/8.5/9ft; no second source for 7.5ft was found, so the value was cut rather than re-sourced. Added ah_blower_strength facet (commercial-grade vs standard/unspecified airflow), sourced to two Shelti/Gold Standard Games product pages that market "commercial blower" / "championship-level air flow". Added combo_conversion_mechanism to the makes_irrelevant list of all five single-game game_type branches (pool_billiards, table_tennis, foosball, air_hockey, shuffleboard), plus the three new facets below to each branch where their game isn't selected. Re-bucketed sb_table_length from invented 9-12/14-16/18-22ft cut points to compact_around_9ft / intermediate_length / full_length_22ft, anchored only to the two sourced endpoints (9ft, 22ft) plus a newly fetched Imperial USA 12ft product confirming an intermediate size exists. Added foosball_rod_bearing_construction facet (nylon_bushing vs other/unspecified), sourced to two Shelti foosball product pages describing Nylon-6 rod bushings. Re-marked foosball_goalie_configuration source from listing to researched — its own hint already said the value is inferred from brand/style naming, not a stated field. Added a judgement naming ITSF as foosball's international governing body (extending the existing wikipedia_table_football reference's supports) and noting table shuffleboard has no equivalent body of its own, distinct from the International Shuffleboard Association which governs the separate cued deck/court game. Changed backfill_cost from high/medium to low on pool_cushion_material, pool_pocket_style, ah_surface_construction, pool_cloth_material, and sb_surface_finish — each backfill_note describes only a zero-inference "default to X unless stated" rule, not a high- or medium-cost one. Added an MDF vocabulary entry (facet: pool_bed_material) — the term was already used in a facet value, a backfill_note, and the top-level summary without one. Added ah_rail_material facet (high_density_aluminum vs other/unspecified), sourced to two Shelti air-hockey product pages, to cover the air-hockey half of the uncovered-rows finding; added a Noise line for pool cabinet finish/wood species (the other half) instead of a facet, since it's cosmetic/furniture-matching and no second source for a value list was reachable this run.
