Scope: "Hiking & Camping Poles" = trekking/hiking poles (adjustable walking poles) and standalone tent/shelter replacement poles; excludes ski poles (skis leaf), whole tents (tents-shelters leaf), ice axes/avalanche gear (avalanche-safety leaf).

Seed: The poles equivalent of harvest_date is the shaft material's failure mode — aluminum bends and can be field-repaired, carbon fiber snaps or chips outright, which a spec sheet never states as a risk, only as a weight number. A rock climber would notice first that no certification body tests trekking-pole strength at all (unlike ice axes/crampons), so every durability claim on a listing is marketing, not a tested rating.

Branches:
product_type -> trekking_pole: routes to shaft/lock/grip facet set, per wikipedia_trekking_pole + outdoorgearlab_trekking_poles defining that set.
product_type -> tent_pole: routes to material/architecture facet set, per wikipedia_tent defining that set.
terrain_and_load -> ultralight_tent_support: anti-shock springs become irrelevant to ultralight thru-hikers, per cleverhiker_best_trekking_poles (springs "prone to breakdown").
terrain_and_load -> offtrail_or_winter: basket_type becomes the next question, per outdoorgearlab_trekking_poles (snow baskets for deep snow).
repair_vs_spare -> repair_one_segment: diameter tier becomes the next question, since a splint/sleeve must match the broken segment's diameter (wikipedia_tent sleeve joint).
repair_vs_spare -> full_spare_pole: connection system becomes irrelevant, since a carried spare is sized generically rather than matched to one tent's hub/sleeve hardware.

Noise (brand spec-sheet rows left out):
price — excluded by rule (price is never a facet).
"Award Winner" / editorial badges (msr_trekking_poles) — marketing recognition, not a buyer-usable spec.
activity marketing tags like "mountaineering/splitboarding/snowshoeing" (msr_trekking_poles) — folded into the terrain_and_load split rather than a separate facet; they map onto the same shaft-material/locking choice.
brand name — excluded by rule (brand is never a facet).
Women's-specific pole variants (different grip size/length range) — folds into existing grip_material/length_adjustment_range_cm facets, no separate value needed.

Corrections:
range fields changed from [min,max] arrays to {"min":...,"max":...} objects per schema.
reference kind values fixed to schema enum: review -> specialist_review (x2), standard -> standards_body.
anti_shock_mechanism cold_start_question reworded to drop "do you want" preamble.

Corrections (2026-10-26):
tent_pole_diameter_tier collapsed from 3 tiers to 2 (slim_under_10mm / 10mm_or_more); wikipedia_tent + wikipedia_geodesic_tent both restate only the same <10mm fiberglass fact, so the invented 10-12mm/>12mm boundaries were dropped rather than left uncited.
Added collapsed_length_cm facet (missing coverage): sourced from fresh fetches of outdoorgearlab_trekking_poles' measured-length table (13.0-26.5in/33-67cm) and cleverhiker_best_trekking_poles' per-pole collapsed lengths (14.25-26in/36-66cm).
length_adjustment_range_cm evidence swapped blackdiamond_trekking_poles -> outdoorgearlab_trekking_poles: re-fetched OGL's comparison table shows Black Diamond Distance Carbon FLZ and REI Co-op Traverse both sized 95-140cm, directly reproducing the range; blackdiamond_trekking_poles' own live catalog no longer carries a 95cm size, so its supports line was corrected to "100cm to 140cm" and dropped as evidence here.
weight_per_pair_g range tightened 245/600 -> 247/595g, matching the exact min/max re-fetched from outdoorgearlab_trekking_poles' measured-weight table (8.70-21.0oz).
Added one Noise line justifying the women's-specific variant omission (OutdoorGearLab's "Best Women's-Specific" award) rather than leaving it unaddressed.
