Aerial Alley-Oop: Assessment Context

Type: assessment application. Source: S03. Evidence: original_performance_guide_reviewed. FS2 describes an airborne rotation up the transition. Contributors include completion near vert and landing flat or on the new edge; incomplete rotation and nose/tail-heavy landings are unsuccessful. This is an instructor assessment context, not an automatic readiness threshold for every rider or feature.

Alley-Oop Convention Conflict

Type: evidence conflict record. Evidence: editorial_comparison_with_index_only_candidate. S01 explicitly names by rotation direction. The search index for candidate S05 describes “Frontside Alley-oop” by the frontside wall and “Backside Alley-oop” by the backside wall. S05's full file was not reviewed. Record a candidate naming conflict and request the relevant original pages before deciding whether this is a curriculum convention, context difference or extraction issue. Do not treat its indexed wording as a completed instruction or normalize it into S01's convention.

Alley-Oop, Skidded on Snow

Type: assessment task. Source: S03. Evidence: original_performance_guide_reviewed. FS1 includes a grounded version on small transitions. Its contributors combine body rotation, flexion for pressure management and low-edge-angle skidding; failures include no edge change and incomplete alignment with trajectory. Relationships: preparatory_task_for aerial alley-oop; distinct_from completed aerial trick. Do not count a grounded drill as evidence that an air was performed.

Entry; line; wall approach; speed management; exit

This page applies the pipe and transition learning framework to Entry; line; wall approach; speed management; exit. Treat the listed dimensions separately rather than assigning one universal cue to the whole topic. Transition shape redirects travel while the rider changes orientation to the local surface. Wall labels describe the feature relation; spin direction is a separate observation.

First-Time Halfpipe Video Lesson

Type: teaching resource. Evidence: written_synopsis_reviewed_video_not_reviewed. S03 is Snowboard Addiction's 2026 Duncan Mainland lesson page. Its synopsis covers starting low, edge-change timing, down-pipe travel, pumping and entry/speed. Store as a linked resource with topics. No video-derived step sequence, exact cue or timestamp has been verified in this packet.

Frontside / Backside Alley-Oop Variant Crosswalk

Type: alias resolution. Evidence: pending_full_source_comparison. Need original S05 pages and clear regular/switch demonstrations for both walls. Compare naming conventions before assigning canonical variant IDs. Partial coverage: PA29-05, PA29-12 and PA29-14. No complete four-way wall/stance matrix is claimed.

Frontside Air: Pipe Context

Type: trick application. Source: S01. Evidence: original_manual_reviewed. The historical manual describes ordinary frontside/backside pipe airs as generally involving a 180-degree redirection to re-enter forward. Import action: enrich the existing frontside-air entity; do not automatically display “frontside 180” as its only name.

Fundamentals Progression Map

Type: learning-path proposal. Evidence: editorial_proposal. Suggested branching structure: This is a proposed navigation map, not an automatic readiness test. Quarterpipe and halfpipe pathways should branch: success in one does not establish every skill in the other.

Handplant Versus Hand Touch

Type: observation policy. Evidence: editorial_proposal. Record whether the hand visibly supports the manoeuvre, merely touches the surface, or cannot be assessed. A brush of the hand should not automatically convert an aerial into a named handplant. Required observation fields: hand identity, contact location, contact interval, board position, approach stance and exit. Use “unknown” when obscured.

Pipe 360, 540 and Higher Upright Spins

Type: technique application queue. Evidence: pending_dedicated_lessons. S03's assessment examples establish that these task categories are used, not a full mechanics curriculum or every possible named combination. Research each verified frontside, backside, Cab and switch-backside application. Link to existing Batch 17 spin entities; add pipe-specific instructions only from reviewed material.

Pipe Air Versus Jump Spin

Type: cross-feature naming proposal. Evidence: editorial_proposal. A return into the same transition changes travel direction. Consequently, a pipe air's name cannot be converted to a jump-spin name merely by looking at landing stance. Store the feature and re-entry geometry with the trick application. Use a reviewed demonstration when estimating rotation; do not calculate it from a trick name alone.

Pipe Inverts and Handplants

Type: cross-feature review queue. Evidence: pending_application_audit. Merge with earlier flip/off-axis and wallride inventories before expanding McTwist, Haakon flip, rodeo and named handplants. Recheck source-specific axes and entry conventions against demonstrations. This packet adds no new validated advanced-invert instruction. A name in a glossary is not sufficient evidence for a full learning progression.

Pipe Trick Variety

Type: run-composition assessment. Source: S03. Evidence: original_performance_guide_reviewed. FS3 combines different tricks across successive hits with sustained speed and amplitude. Examples include switch, alley-oop, 360/540 rotations and grabs. Import action: attach as run-level assessment rather than generating an unrestricted list of verified trick combinations.

Pumping in Halfpipe Transitions

Type: technique family. Evidence: partial_source_coverage. S04 lists pumping tasks, and S03's written synopsis mentions pumping. These do not provide enough reviewed detail here to establish a full timing lesson. Candidate S07 could not be opened because of retrieval size limits. Required next research: original text explaining ascent/descent timing, pressure management, common errors and the difference between pumping for speed and absorbing terrain. Relationship: enrich the existing roller-pumping concept from Batch 26; retain terrain-specific applications.

Method

Pumping; absorption; wall edge control; linked hits

An edge supports direction through its relation to snow and travel. Edge angle is distinct from board heading and skid angle. The source packets identify pumping as a transition skill but do not establish a complete timing curriculum. This remains an instruction gap. Transition shape redirects travel while the rider changes orientation to the local surface. Wall labels describe the feature relation; spin direction is a separate observation.

Rare Handplant Mechanics and Alias Resolution

Type: instructional and terminology gap. Evidence: pending_research. Prioritize J-Tear, Sadplant, Phillips 66, Rotten Eggplant, Warlock and higher Elguerial applications. Compare original definitions and demonstrations before importing fixed hand/rotation fields. A historical spelling or a familiar skate name alone is insufficient for a completed snowboard card.

Same-Wall Return Versus Transfer

Type: geometry template. Evidence: editorial_proposal. Store departure surface, hand-support surface and landing surface independently. Link same-wall and transfer applications through their parent trick; preserve separate technique blocks. Batch 06's Andrecht Transfer already has a written source summary. Its unresolved feature geometry remains unresolved here: a newly found event name does not fill that gap.

Stall, Press and Slide Crosswalk

Type: classification proposal. Evidence: editorial_proposal. Describe movement and contact separately: These properties can overlap. Do not equate a flatland press, coping stall and rail slide simply because the rider loads the same end of the board. Feature context belongs in each application.

Switch Variant Expansion Rules

Type: import policy proposal. Evidence: editorial_proposal. Do not create a verified switch version for every forward trick through automatic multiplication. A candidate combination can be indexed as unverified_application. Promotion requires a source identifying the variant and enough evidence to establish takeoff stance, direction, axis and landing. Cab terminology covers switch-frontside naming; it does not validate every amplitude, degree or invert combination.
