# AI Tutor Dataset Built directly on `` (, 886 real instruction/response pairs) and `` (26 real-definition terms, 3 explicitly PENDING). This file adds the Academy-specific layers requested for Phase 13 — flash cards, keyword/alias mapping, and topic mapping — without inventing any new fact. ## 1. Training prompts / instruction dataset Reuse `` as-is — 886 pairs, each with `id`/`instruction`/`response`/`sku`/`category`/`bucket`/`citation`. Not duplicated here. ## 2. Lesson chunks (retrieval-ready) Each course file in `` is already organized into numbered Module/Lesson blocks (20 in ``, 17 in ``, 19 in ``, 14 symptom lessons in ``, 5 in ``) — each block is a self-contained retrieval chunk (heading + real content + exercise/PENDING note). An AI tutor should retrieve by module heading, not by whole-file dump. ## 3. Semantic / retrieval chunks Reuse the 3 existing search indexes rather than building a 4th: `` , `` (, technical keywords), `` . ## 4. Exam questions Reuse `` (this pass, Phase 14) once generated — every certification question across every course module in this file already doubles as an exam-bank source question. ## 5.

FP-12A: 0-15ms / 0-500cm. _Source: ._ 3 terms have no real definition and are intentionally excluded from flash cards (quizzing on a PENDING term would train the AI tutor to state an unverified fact as settled): A2B, CAN (bus), Phase / Polarity (Speaker install). ## 6. Keyword mapping / aliases - `MOST` = Media Oriented Systems Transport - `THD` = Total Harmonic Distortion - `SNR` = Signal-to-Noise Ratio - `MBUX` = Mercedes-Benz User Experience (head unit) - `REM` = Remote Turn-On - `DSP` = Digital Signal Processor ## 7. Topic mapping (keyword → course file) | Topic keyword | Course file | | --- | --- | | Time alignment, phase, crossover, EQ, gain (DSP) | `` | | Bridging, protection circuit, class AB/D, wiring | `` | | Impedance, frequency response (speaker) | `` | | MOST, Burmester, MBUX, W206 | `` | | Fuse, ground loop, no sound, no power | `` | | Wiring gauge, fuse placement, mounting | `` | | Dealer exam, pass criteria | `` | | Engineer tier, knowledge gap ownership | `` | | Positioning, objection handling | `` | | Buying guide, common mistakes | `` | ## 8. What the AI Tutor must NOT do Per every prior CONTENT-00X rule applied consistently in this Academy: never state a price, never state a warranty duration, never claim a vehicle-to-product fit beyond the 6 vehicle trims with real speaker-architecture data, never answer a BMW compatibility question, never resolve one of the project's known data conflicts on its own authority (FP-6A-V2 power spec, FX-4's two AWG figures, VF8 speaker-count mismatch) — surface the conflict instead of picking a side.
