Scope: Medical Tape, Bandages & Dressings — individual adhesive tape, roll/wrap bandages, stick-on (Band-Aid style) bandages, and gauze/wound dressing products. Excludes packaged First Aid Kits (sibling leaf) and non-medical packing/office Tape (sibling leaf, line 802 of catalog.json). Elastic/cohesive compression wraps (bandage_or_wrap) stay here as wound-care consumables; rigid/structured orthopedic supports belong to the sibling leaf support-braces (status: planned) once it is built.

Seed:
1. Equivalent of the tyre example (a number on every listing that needs a judgement attached): FDA Class I / 510(k)-exempt status. It's effectively on every listing's regulatory footprint, but it only means the device *category* was judged low-risk by the FDA, not that any given product's performance was tested — same catch as treadwear grade only being comparable within one brand's own test.
2. Pastry-chef persona notices: they'd key straight in on "moist wound healing" as a ratio problem, not a binary — a dressing isn't "wet=bad, dry=good," it's about matching the dressing's moisture-handling to the wound's exudate output, the same way a dough's hydration ratio has to match its flour and environment or the recipe fails one way or the other.

Branches:
- product_type: adhesive_tape branch asks tape_backing_material + adhesive_chemistry, drops bandage/dressing facets — supported by wiki_bandage/wiki_adhesivebandage naming tape and bandage as distinct main types with their own sections.
- product_type: gauze_or_wound_dressing branch asks dressing_contact_layer + exudate_absorbency + antimicrobial_treatment + sterility — supported by pmc_dressing_review's Table 1/2 keying dressing choice to exudate level and infection risk.
- wound_contact: touches_open_wound then_asks sterility/exudate/antimicrobial — supported by fda_878_gauze + pmc_dressing_review treating these as wound-contact-specific concerns, not tape/wrap concerns.

Noise (spec-sheet rows left out):
- Tape/bandage color (tan/white/blue food-safe blue) — cosmetic/compliance niche, not a buyer-expertise axis; one line in wiki_adhesivebandage "Colors" section, not worth a facet.
- "Hand-tearable" convenience claim on Coban/Micropore — a packaging convenience, not a product-type-defining spec.
- Pack count / dispenser format — not an expert axis, just a quantity.
- Reusability (washable elastic bandage) — plausible but no fetched source stated it; dropped rather than invent.
- Transdermal patches (adhesive bandage "Variants" section) — a drug-delivery product, not a wound/securing product; out of scope for this leaf.

Corrections (2026-10-26):
- Replaced dead brand_coban URL (american-hospitalsupply.com, HTTP 404, no Wayback capture) with a live mfimedical.com Coban LF product page confirming self-adherent closure, porous/breathable, latex-free, sterile/non-sterile, and 1-6in widths.
- roll_width.range lowered min 0.5→1 and max 6 is now confirmed by two live sources (brand_coban 1-6in configs; brand_mtape_zincoxide ~1-2in), closing the single-source gap on the dead citation.
- Added wound_type facet (pressure_ulcer/surgical_wound/burn/infected_wound/epithelializing_or_superficial), cited to pmc_dressing_review Table 1 and wiki_dressing's "Types" section (pressure ulcers, burn wound, infected wounds); wired into wound_contact's touches_open_wound/intact_skin_only branches.
- Replaced fda_878_part_listing (no per-code class label) with three per-code FDA classification pages (NAC/878.4018, NAD/878.4020, NAE/878.4022), each stating Device Class 1 and 510(K) Exempt directly; wired into regulatory_classification and the judgement's evidence.
- adhesive_tape branch now also asks stretch_conformability; bandage_or_wrap branch now also asks breathability.
- Added scope-boundary line (Scope, above) distinguishing bandage_or_wrap compression wraps from the sibling support-braces leaf.
- breathability.source changed listing→researched per its own backfill_note (usually inferred from backing material, not a stated listing claim).
- Added vocabulary entries for "Foam dressing," "Maceration," and "Crepe bandage."
- Rejected: none of the 8 required fixes were rejected; all were applied as above.
