## 🛠️ Frameworks & Methodologies

### Tier 1 — Diagnostic Frameworks

#### Memory Failure Taxonomy (MFT)
| Failure Class | Symptom | Typical Fix |
|---------------|---------|-------------|
| **Weak Encoding** | Vague familiarity, no detail | Elaboration, dual coding, bizarre imagery |
| **Cue Deprivation** | Knows it in context, blank in exam | Context-stripped retrieval drills |
| **Interference** | Confuses similar items | Contrast encoding, interleaved discrimination |
| **Decay / No Retrieval** | Knew it last week, gone now | SRS + cumulative review |
| **Overload** | Drops after item 12 | Chunking, palace segmentation, reduce set |

#### Encoding Specificity Audit
Ask: *Will the test cue match the study cue?* Mismatch → add multiple retrieval routes and cold recall.

### Tier 2 — Mnemonic Architectures

#### Method of Loci (Memory Palace)
- **Best for**: ordered sequences, multi-domain decks, narrative material, 20–200 items
- **Protocol**: Select familiar route → assign loci (1 per item) → insert bizarre interactive images → traverse for retrieval
- **Advanced**: Thematic wings, nested sub-palaces, palace reuse with ghost markers

#### Major System / Peg Words (00–99)
- **Best for**: numbers, dates, formulas, ordered lists with index
- **Protocol**: Pre-memorized phonetic pegs + composite images

#### Story Chain & Link Method
- **Best for**: unordered lists, process steps, causal chains
- **Protocol**: Exaggerated narrative linking itemₙ to itemₙ₊₁

#### Chunking & Hierarchical Trees
- **Best for**: technical taxonomies, anatomy, API structures
- **Protocol**: 4±1 chunks per level, meaningful labels, progressive disclosure

#### Acronym / Acrostic / Rhyme Engines
- **Best for**: fixed sequences (e.g., RGB, PEMDAS, cranial nerves)
- **Protocol**: Build from user content, verify each letter mapping

#### Dual Coding Overlay
- **Best for**: abstract concepts, definitions, foreign vocabulary
- **Protocol**: Verbal label + distinct visual scene + optional motor gesture

### Tier 3 — Spaced Repetition Engineering

#### Algorithm Selection
| User Profile | Algorithm | Notes |
|--------------|-----------|-------|
| Anki power user | FSRS | Optimize retention target (e.g., 90%) |
| Beginner | Leitner 5-box | Physical or app-agnostic |
| Exam crunch (<30 days) | Modified SM-2 + interleave | Higher early frequency, then taper |
| Maintenance | Expanding retrieval (1-3-7-30) | Low load, long horizon |

#### Desirable Difficulty Calibration
- Target **successful recall with effort** (~70–85% on cold tests)
- Too easy → interval grows too fast, illusory knowing
- Too hard → collapse motivation; shrink chunk size

#### Interleaving vs. Blocking
- **Block** when building initial encoding (Day 1–2)
- **Interleave** similar confusable items after baseline encoding (Day 3+)

### Tier 4 — Retrieval Practice Protocols

1. **Cold Recall** — no cues, timed, write/speak before peeking
2. **Cue-Graduated Recall** — category → first letter → full reveal
3. **Free Recall Listing** — dump everything on a topic in 2 min, gap-fill
4. **Teach-Back** — explain aloud without notes; errors = drill queue
5. **Exam Simulation** — matched format, time pressure, arbitrary item order
6. **Palace Walkthrough** — spatial traversal under time limit

### Tier 5 — Domain Playbooks

| Domain | Primary Stack | Watch-Out |
|--------|---------------|-----------|
| Language vocab | Dual coding + SRS + sentence mining | Interference between cognates |
| Medical/Anatomy | Palace + chunk trees + discrimination drills | Similar terminology |
| Law/Code | Peg dates + story chains for elements + issue spotting drills | Verbatim vs. rule gist |
| Programming APIs | Procedure memory via muscle drills + chunk by module | Confusing similarly named methods |
| Speeches/Presentations | Loci by section + keyword pegs | Rote without meaning |
| History/Timelines | Number pegs + palace wings per era | Date-item orphaning |

### Metrics Dashboard (User-Facing)
Track weekly:
- **Cold Recall %** (items recalled / items attempted)
- **Latency** (seconds to first correct word)
- **Confusion Pairs** (which items swap)
- **Review Minutes / Day** vs. plan
- **Retention at T+7 and T+30** for sample probes

Use metrics to retune intervals and swap encoding for chronic failures.
