Scope: Fishing Storage & Tools = containers that hold tackle/rods (tackle boxes, bags, satchels, dry boxes, rod cases/tubes/socks/racks) plus the hand tools anglers carry (pliers/line cutters, scales/lip grippers, line spoolers). Excludes rods/reels, terminal tackle (hooks/lures/line) and nets/traps, which are sibling leaves.

Seed: (1) The fishing-storage equivalent of the steel-hardness/trade-off example is jaw-and-cutter material on pliers: 420/440C martensitic stainless or titanium-coated jaws with a tungsten-carbide cutter insert cut braid cleanly and resist saltwater better than plain stainless, at a cost premium over a bare stainless notch-cutter. (2) A guide/charter captain who re-rigs gear daily would notice the water-ingress and corrosion-protection claims first — whether a box is just "water-resistant" (gasket/latch, splashproof) versus genuinely sealed, and whether Zerust/VCI treatment needs the box to stay mostly closed to work — before a first-time buyer would even register these as different things.

Branches: storage_tool_type -> tackle_storage routes to container_form/compartment_organization/water_resistance/corrosion_protection/closure_type/carry_format, supported by flambeau_nav + kastking_nav splitting hard/soft storage from tools. -> rod_storage routes to rod_case_form/rod_length_fit, supported by flambeau_rodtubes (telescoping tube) + kastking_nav (rod socks vs racks). -> hand_tool routes to tool_kind, supported by kastking_nav grouping pliers/scales/spoolers as a distinct "Tools & Accessories" tier. tool_kind -> pliers_or_cutter/scale_or_gripper/line_spooler each route to their own facet set per piscifun_pliers/piscifun_gripper/piscifun_spooler and kastking_cutthroat/kastking_scale corroboration.

Noise: bait buckets/aerators/worm care/minnow traps (Flambeau's own "Bait Storage" tier — live-bait keeping gear, overlaps the Nets & Traps sibling leaf, not core to "storage & tools"); kids tackle boxes (market segment, not a technical facet); item/SKU numbers and price (never facets); battery type (AAA) on digital scales (too granular for this leaf); "Made in USA" claim (marketing, not a buyer-judgement attribute).

Corrections (2026-10-26):
- Added `tool_kind` to `makes_irrelevant` in the `tackle_storage` and `rod_storage` branches of `storage_tool_type` (branch-graph bug: tool_kind was previously left dangling, neither asked nor dropped, on those two branches).
- Added `fillet_knife` as a fourth `tool_kind` value with its own branch and three new facets (`fillet_knife_blade_material`, `fillet_knife_blade_length`, `fillet_knife_blade_flex`), sourced from kastking_fillet_knife + kastking_fillet_knife_folding (fetched this run; KastKing's fillet-knife product pages, not on their public nav search but found via their sitemap).
- Added `plier_nose_shape` facet (straight-nose vs split-ring-nose), sourced from kastking_cutthroat (already cited) plus piscifun_pliers (fetched this run — "stainless steel jaws come with split ring tip").
- Added `scale_water_resistance` facet under `tool_kind = scale_or_gripper`, sourced from kastking_scale (title: "KastKing Water Resistant Digital Fishing Scale") and piscifun_gripper ("water-resistant construction," "high-grade stainless steel"), both re-fetched this run to confirm the quotes.
- Added `rod_rack_capacity` (numeric, 10-16 rods) under the `rod_storage` branch, sourced from two KastKing rod-rack product pages fetched this run: kastking_v10ls_rack (10 rods / 18" wall space) and kastking_v16_rack (16 rods / 1.5 sq ft) — same brand, different product lines; no independent second brand's rod-rack spec page was found this run.
- Added `backpack_capacity_liters` (34-40 L) and `pocket_count` (14-20 pockets) under the `tackle_storage` branch, sourced from kastking_karryall (already cited, 40L/14 pockets) plus kastking_baitboss (fetched this run, 34L/20 pockets) — again same brand, different product lines.
- Relabeled `source` from `listing` to `researched` for container_form, compartment_organization, closure_type, carry_format, rod_case_form, rod_length_fit, scale_mechanism, weight_capacity, reel_compatibility: every citation for these is a manufacturer-direct page, never an actual retail-marketplace listing (Amazon/Bass Pro/Tackle Warehouse all 403/404'd when checked), so per the LEAN default these are `researched` with `backfill_cost: low`, now consistent with jaw_and_cutter_material/corrosion_protection which were already tagged that way on the same evidentiary footing.
- Re-tagged vocabulary "Split-ring pliers" from `jaw_and_cutter_material` to the new `plier_nose_shape` facet (nose geometry, not jaw/cutter material) and "Lip gripper" from `scale_mechanism` to `tool_kind` (it names which tool this is, not the weighing mechanism).
- Added a "Teflon coating" vocabulary entry under `jaw_and_cutter_material`, matching the existing `stainless_with_teflon_coating` facet value that had no definition.
- Lowered the 420/440C corrosion-comparison judgement's confidence from `medium` to `low` (the comparison itself still rests on one general metallurgy source, wikipedia_stainless_steel) and added a new low-confidence judgement for the Zerust "<1 air exchange/day" claim, flagging it as resting on Flambeau's own FAQ alone — no independent VCI-industry source was reachable this run to corroborate either number.
- Rejected the single-source IPX7/IPX8 finding as-is: these are definitions stated by the standard's own governing body (IEC 60529, via its Wikipedia page), and the LEAN rule for safety/standards facets is to cite the standard body itself, not to seek a second corroborating source for the standard's own definition of its own terms — no change made.
