1) Math Row Library (Primary + Secondary)

Paste rows as needed into your Z0–Z3 table.

Z	Skill (what must work)	Top Failure Mode	Sensor(s)	Repair Loop (what to do)
Z0	Number sense (magnitude, place value, fractions/decimals intuition)	Nonsense answers, magnitude blindness	RCR, VI	Number Sense Thickening (daily 5–10 min estimation + compare + mental)
Z0	Accuracy micro-habits (copying, signs, units)	“Careless clusters”	CDS, TPC, RER	Check Discipline Loop (units + inverse check + last-line scan)
Z0	Algebra manipulation (Sec)	Small slips cascade everywhere	ASI, RER	Algebra Spine Thickening (short daily drills + spaced retest)
Z0	Arithmetic fluency (Pri/Sec)	Slow, overload, time collapse	TPC, SF	Speed-from-Stability Loop (stability first → light timing → exam timing)
Z1	Model selection (word problems)	Wrong model/method chosen	MHR, TS	Model/Method Lock Loop (cue → model → steps → 2 transfer skins)
Z1	Multi-step chain execution	Step breaks, missing steps	SI, CFR	Step Scaffold + Checkpoint Loop (forced steps + mid-checkpoints + explain-back)
Z1	Question interpretation (graphs/geometry/wording)	Misread constraints	IPR, SI	Interpretation Drill Loop (underline constraints → restate → solve)
Z1	Equation/inequality solving	Correct method, wrong transformations	ASI, RER, TTC	Error Closure Loop (classify → micro-drill → spaced retest → transfer retest)
Z1	Geometry reasoning	Assumption errors, diagram lies	SI, IPR	Diagram Discipline Loop (mark given → mark implied → state why)

Z1	Calculus procedures (A-Math)	Works only on standard templates	TS, TTC	Transfer Variants Loop (direct → disguised → integrated variant)
Z2	Mixed-topic integration	Can do topics, fails mixed sets	MSI, VI	Mixed Set Switching Loop (weekly mixed sets + closure cycle)
Z2	Exam section pacing	Spends too long early	TPC, SC	Pacing Protocol Loop (time boxes + checkpoint times)
Z2	Proof/justification marks (A-Math)	Cannot explain why steps valid	SI, EAR (reasoning)	Explain-Back Loop (write 1-line justification per step)
Z3	Full-paper reliability	Big swings across papers	VI	Variance Control Weekly Cycle (1 paper + 1 repair cycle/week)
Z3	Timed stability	Accuracy collapses when timed	TPC, CDS	Timed Stitching Ramp (stable untimed → lightly timed → exam timed)
Z3	Recovery after error	One slip destroys remainder	RAE, CFR	Reset Protocol (stop → breathe → isolate → salvage marks → resume)

2) Science Row Library (Primary + Secondary)

Use this for Primary Science + (later) Bio/Chem/Physics.

Z	Skill	Top Failure Mode	Sensor(s)	Repair Loop
Z0	Concept core (definition + mechanism)	Misconception repeats	MR, SUD	Concept Core Lock (1-sentence core → examples/non-examples → 48h retest)
Z0	Key terms / marking language	“Knows it” but loses marks	KPR	Keyword Precision Loop (keyword bank + forced inclusion drills)
Z1	Explanation chain (claim→mechanism→result)	Broken causal logic	ECI	Explanation Structure Loop (template answers + rewrite to full chain)
Z1	Variable control reasoning	Confuses cause/effect	ECI, IPR	Variables Mapping Loop (change X → predict Y → explain mechanism)
Z1	Command word interpretation	Answers wrong question type	IPR	Command-Word Parse Loop (what is asked → answer shape)
Z2	Scenario application (transfer)	Novel context breaks concept	TS	Scenario Transfer Loop (3 scenarios per concept: direct/disguised/integrated)
Z2	Mixed-topic paper stability	Topic isolation	MSI, VI	Mixed Integration Loop (mixed sets + closure discipline)
Z3	Timed explanation quality	Quality collapses timed	TPC, SC	Timed Stitching + Stamina Loop (short→medium→full under timing)
Z3	Full-paper consistency	Swings across papers	VI	Variance Control Weekly Cycle (paper + repair target)

3) English Row Library (Primary + Secondary)

Works for Primary English + Secondary English.

Z	Skill	Top Failure Mode	Sensor(s)	Repair Loop
Z0	Active vocabulary output	Passive vocab only	AVO	Active Vocab Conversion (collocations → sentence → rewrite variants)
Z0	Grammar control under load	Grammar drifts when timed	GSI, TPC	Grammar Under Load Loop (micro-drill → timed apply → edit pass)
Z0	Sentence clarity	Rambling / unclear meaning	WSI (micro), ECR-Eng	Clarity Rewrite Loop (shorten + simplify + keep meaning)
Z1	Comprehension: evidence anchoring	Unanchored answers	CER/EAR	Evidence Loop (locate clue → paraphrase → support with phrase)
Z1	Inference (implied meaning)	Literal-only reading	IA	Inference Drill Loop (why/how/intent + evidence)
Z1	Question-type parsing	Wrong command word response	IPR	Command-Word Parse Loop (label question type → answer shape)
Z2	Summary precision (Sec)	Too long / wrong points	SPS	Summary Compression Loop (extract → group → compress → check relevance)
Z2	Writing structure	No planning, weak paragraph logic	WSI	Writing Production Loop (plan → draft → relevance pass → language pass)
Z2	Editing discipline	Cannot catch own errors	ECR-Eng	Two-Pass Edit Loop (content pass → grammar pass with checklist)

Z3	Score stability across papers	Mark swings	VI	Variance Control Weekly Cycle (1 paper + 1 repair cycle/week)

4) Exam OS Rows (PSLE / O-Levels) — plug into PSLE OS / O-Levels OS

Use these rows for your exam-level pages.

Z0	Error closure discipline	Same errors survive weeks	RER, TTC, ECR	Error Closure Loop
Z1	Transfer handling	New skins break performance	TS	Transfer Variants Loop

Z3	Recovery after error	Cascade failure	RAE, CFR	Reset Protocol

Next (pick one — I’ll do it immediately)

I convert all 8 Subject OS pages into the exact same table length + same row positions (so every page looks uniform to Google/AI).
I generate Chem / Physics / Bio / Chinese / Humanities in the same Almost-Code format.

Just reply: “1” or “2 + list subjects”.
