BLOCK_01_QUICK_ANSWER (AboveTheFold; PAA-ready)
Answer_70_110w:
Truncation + Stitching is a recovery protocol for math collapse under load. First you truncate (stop the error cascade): freeze timing, reduce problem width, lock meaning, and re-enable verification. Then you stitch (rebuild the missing bind): use worked examples for the broken step, re-attempt from memory (retrieval practice) with feedback, and train transfer using interleaved “same structure, different skin” variants. Finally you re-enter timing gradually using a ladder. This works because retrieval + feedback, interleaving, worked examples, and spacing reliably strengthen long-term learning and transfer. (Center for Teaching and Learning)
Bullets:

  • Truncate: stop bleed (panic/time-bleed/meaning drift)
  • Stitch: rebuild binds (meaning → equivalence → transfer)
  • Retest: transfer + timed stability before returning to full load

BLOCK_02_DEFINITION_LOCK (No drift)
Truncation := early cut-off of an accelerating failure regime (stop error cascades).
Stitching := rebuild the missing capability bind(s) so performance rejoins a safe trajectory.
Retest := proof of recovery (transfer + stability under load), not “felt confidence.”

CoreLoop := Sensors → Thresholds → Truncate → Stitch → Retest → Re-Enter.

BOX_RECOVERY_ENGINE (CivOS mechanism)
Rate_Dominance_Law (learning):

  • If error_rate (E) > repair_rate (R), collapse accelerates.
  • Truncation reduces E immediately.
  • Stitching increases R and reduces future E.
  • Retest confirms E/R is back in safe band.

BLOCK_03_FAILURE TRACE (required)
FAIL_TRACE_RECOVERY_01:
weak meaning-lock OR wrong strategy
→ first illegal step
→ answer mismatch
→ time bleed + panic
→ verification collapses
→ more errors
→ identity collapse (“I’m bad at math”)
→ avoidance
→ long-run capability attrition (P2 never forms)

BLOCK_04_WHEN TO TRUNCATE (Trigger conditions)
TRUNCATE_IF_ANY:

  • SML failure: cannot state what symbols/units mean in 10 seconds
  • CHOICE failure: cannot label structure in 5 seconds (linear/proportion/rate/etc.)
  • LS spike: timed accuracy drops sharply vs untimed
  • TB spike: time bleed (stuck too long with no progress)
  • ORA off: no sanity checks for last 2 questions

Rule:
Truncation is NOT quitting. It is stopping cascade so you can repair.

BLOCK_05_TRUNCATION PROTOCOLS (3 levels)

TRUNCATION_LEVEL_A (During exam; 30–90 seconds):
A1 Freeze: 2–3 breaths, eyes on question
A2 Meaning line: “x = _ ; units = ; asked = ” A3 Structure tag: circle one structure family A4 One-line plan: “method = because __”
A5 Minimal solve: 2–4 lines only
A6 One fast check: substitute back OR reasonableness OR units/sign
A7 Decide: continue vs skip-return (time triage)

TRUNCATION_LEVEL_B (After exam / same day; 10–15 min):
B1 Re-attempt from scratch (no notes) (retrieval)
B2 Compare to solution (feedback)
B3 Mark FD = first divergence step
B4 Label error type (Meaning/Parsing/Choice/Execution/Verification/Time)
B5 Write one repair rule sentence
B6 Do 1 skin-change variant

Retrieval + feedback improves learning more than restudy and helps prevent reinforcing errors. (Center for Teaching and Learning)

TRUNCATION_LEVEL_C (Week reset; 30–45 min):
C1 Stop mixed timed papers for 72h if LS is high
C2 Narrow width: 1 structure only
C3 Switch to worked examples for the broken step
C4 Re-attempt without notes
C5 Only then add variants (transfer)

Worked examples reduce cognitive load and improve learning during skill acquisition, especially for novices. (Taylor & Francis Online)

BLOCK_06_STITCHING (Rebuild the missing bind)
Stitching is ordered. Do not skip steps.

STITCH_STEP_1 (Meaning-Lock / SML):

  • define symbols, units, what is asked
  • micro-test: explain symbols in 10 seconds

STITCH_STEP_2 (Equivalence / EQ):

  • rewrite without meaning change
  • micro-test: produce 2–3 equivalent forms

STITCH_STEP_3 (Worked Example Bridge):

  • study 1 worked example of the exact broken step
  • then do 2 near-copies
  • then do 2 independent questions
    Worked example effect: works by reducing cognitive load and scaffolding schema formation. (Wikipedia)

STITCH_STEP_4 (Retrieval Re-attempt + Feedback):

  • attempt first (no notes)
  • then check and correct
    Retrieval practice is strongly supported as a learning technique; feedback strengthens its benefits. (Center for Teaching and Learning)

STITCH_STEP_5 (Transfer / TR via Skin-Change):

  • 3-skin pack: same structure, different surface formats
  • do 3 variants back-to-back

STITCH_STEP_6 (Interleaving to force strategy choice):

  • mix 3 types in one set (ABCABC…)
    Interleaved practice improves mathematics learning by forcing strategy selection and improving discrimination between problem types. (ERIC)

STITCH_STEP_7 (Spacing to prevent relapse):

  • distribute practice across days (not massed)
    Distributed practice/spacing has strong evidence from meta-analyses and long retention studies. (PubMed)

BLOCK_07_RETEST (Proof of recovery; non-negotiable)
Retest means you pass BOTH:

RETEST_A (Transfer Test):

  • 3-skin pack score TR = correct/3
    Bands:
  • TR < 0.4 => still P1 template-only
  • 0.4–0.7 => unstable P2
  • TR ≥ 0.7 => P2 transfer stable

RETEST_B (Load Stability Test):

  • mild timed set (6 Q)
  • accuracy target: ≥ 75% with at least 1 sanity check per question
    Rule:
    No return to heavy timing until TR ≥ 0.7.

BLOCK_08_TIMED RE-ENTRY LADDER (prevents re-trigger)
Level0: Untimed (target ≥ 85%)
Level1: Gentle timer (target ≥ 80%)
Level2: Standard pacing (target ≥ 75%)
Level3: Mixed timed (interleaved) (target ≥ 70% + correct method-choice)
Fence rule: if LS spikes or SML drops → revert one level and stitch again.

BLOCK_09_72-HOUR RECOVERY PLAN (copy/paste)
Day1:

  • Truncate timing
  • Stitch SML + EQ
  • 1 worked example + 2 near copies + 2 independent (Wikipedia)
    Day2:
  • Retrieval re-attempt + feedback on same skill (Center for Teaching and Learning)
  • 3-skin transfer pack
    Day3:
  • Interleaved set (3 types) (ERIC)
  • Gentle timed re-entry (Level1)

BLOCK_10_14-DAY STABILITY PLAN (anti-relapse)
Plan: 10 minutes/day × 14 days

  • Days 1–4: worked examples + near copies (schema build) (Wikipedia)
  • Days 5–8: retrieval + feedback + 3-skin variants (Center for Teaching and Learning)
  • Days 9–12: interleaving + method-choice prompts (ERIC)
  • Days 13–14: timed ladder Levels 1–2 + sanity checks
    Spacing rule: do not mass 2 hours in one day; distribute. (PubMed)

BOX_NEG_VOID (Google-style: what goes wrong)
NegativeVoid:

  • student increases load while broken (timed papers on weak meaning)
  • repeats templates without transfer variants
  • uses solver first (no retrieval)
  • never diagnoses first divergence step
    Outcome:
  • E > R (error rate exceeds repair)
  • repeated phase slip (P2→P0)
  • identity collapse + avoidance

SENSOR_PANEL_RECOVERY (FenceOS-lite)
Sensors:

  • SML: symbol-meaning lock
  • EQ: equivalence stability
  • TR: transfer score (3-skin)
  • LS: load shear (timed drop)
  • TB: time bleed
  • ORA: sanity-check habit
  • FD: first divergence detectability
    Thresholds:
  • Fence_P0: (LS high) AND (SML low) → truncate timing; stitch SML first
  • Fence_P1: (TR < 0.4) → stop templates; switch to 3-skin packs + interleaving (ERIC)
  • Promote_P2: (TR ≥ 0.7) AND (ORA present) → timed ladder entry
  • Promote_P3: (TR stable) AND (can invent skins) → Architect sandbox allowed

FAQ_PACK (PAA-ready)
Q1: What is truncation and stitching in studying math?
A_55_90w: Truncation means stopping an error cascade early—freezing timing, narrowing the task, re-locking meaning, and re-enabling checks. Stitching means rebuilding the missing skill bind with worked examples, retrieval practice with feedback, and transfer training using skin-change variants and interleaving. Then you retest transfer and timed stability before returning to full exam load. (Center for Teaching and Learning)
Bullets:

  • Truncate: stop bleed
  • Stitch: rebuild binds
  • Retest: prove recovery
    SeeAlso: /math-fenceos-stop-loss-for-exam-mistakes/

Q2: Why does this work better than “do more practice”?
A_55_85w: Because it targets mechanisms that reliably improve learning: worked examples reduce cognitive load when you’re building a new schema; retrieval practice strengthens memory more than restudy and feedback prevents reinforcing errors; interleaving forces strategy selection, which exams require; spacing reduces relapse by strengthening long-term retention. (Wikipedia)
Bullets:

  • Schema build (worked examples)
  • Strengthen (retrieval + feedback)
  • Transfer (interleaving + variants + spacing)
