0) LANE PURPOSE
========================================================
SG×EDU×ENG lane answers:
- What must a Primary learner do in English (Z2)?
- What are the smallest gate skills that control those tasks (Z0)?
- How do we measure P0–P3 stability under load?
- How do we route repair using FENCE loops?
LOCK:
Primary English is skill-based and must be trained as:
Receptive (read/listen) + Productive (write/speak) + Language use (grammar/vocab in context),
with TRACE discipline (show evidence line) built into every task form.
========================================================
1) Z3 CONTAINERS (SYLLABUS + EXAM CONTAINER)
========================================================
1.1 Primary English Syllabus Container (learning outcomes basis)

========================================================
2) Z2 TASK FORMS — PSLE ENGLISH (0001)
========================================================

========================================================
3) Z0 GATE ATOMS — THE “SMALLEST SKILLS” THAT CONTROL PSLE RESULTS
========================================================
Naming rule:
SG×EDU×ENG×Z0×Learner×Atom×<ATOM-ID>
3.1 Writing Gates (Paper 1)
- ENG-PURPOSE-AUDIENCE-REGISTER
- ENG-IDEA-GENERATION-SELECTION
- ENG-COHERENCE-PARAGRAPH-CHAIN
- ENG-COHESION-LINKERS-REFERENCE
- ENG-SENTENCE-CONTROL (tense/agreements/clarity)
- ENG-PUNCT-SPELL-ACCURACY
- ENG-NARRATIVE-IRREVERSIBILITY (NIT hook; see Sensors)
3.2 Language Use Gates (Paper 2)
- ENG-GRAMMAR-IN-CONTEXT
- ENG-VOCAB-IN-CONTEXT
- ENG-CLOZE-SENSEMAKING
- ENG-EDITING-ERROR-DETECT
- ENG-SYNTHESIS-TRANSFORMATION
- ENG-VISUALTEXT-INFERENCE
- ENG-COMPREHENSION-LITERAL
- ENG-COMPREHENSION-INFERENTIAL
- ENG-COMPREHENSION-EVALUATIVE
(These mirror the PSLE AOs: understanding literal/inferential/evaluative + appropriate language use in context.) :contentReference[oaicite:10]{index=10}
3.3 Listening Gates (Paper 3)
- ENG-LISTEN-MAINIDEA-DETAIL
- ENG-LISTEN-INFERENCE
- ENG-LISTEN-EVALUATION
(PSLE listening assesses understanding of spoken texts at literal/inferential/evaluative incl main ideas/details.) :contentReference[oaicite:11]{index=11}
3.4 Oral Gates (Paper 4)
- ENG-READALOUD-FLUENCY-EXPRESSION
- ENG-PRONUNCIATION-CLARITY
- ENG-SBC-IDEA-OPINION-CLARITY
- ENG-SBC-VOCAB-STRUCTURE-RANGE
- ENG-SBC-FLUENCY-GRAMMAR-ACCURACY
(Oral AOs: read aloud fluently/expressively; express opinions; speak fluently with clear pronunciation + grammatical accuracy + range of vocab/structures.) :contentReference[oaicite:12]{index=12}
========================================================
4) P0–P3 PHASE RUBRIC (ENGLISH-SPECIFIC)
========================================================
P0 (Breakdown):
- cannot complete Z2 task without heavy prompting
- meaning unstable; frequent misreads; output collapses under time
P1 (Scaffolded):
- can do task with templates; brittle under variation
- common signature: “template-only” + weak inference + language errors spike
P2 (Gate Stable / Safe Band):
- completes Z2 task under time + variation with stable accuracy
- shows TRACE line (evidence/reason) for comprehension/inference
- writing stays coherent; oral stays intelligible + controlled
P3 (Coach Stable):
- can self-diagnose, correct errors, transfer across genres
- can explain why an answer is correct and why alternatives fail (trace discipline)
========================================================
5) SENSORS (HD) — WHAT FAILS FIRST IN REAL STUDENTS
========================================================
5.1 TRACE SENSOR (core)
- SensorID: ENG-TRACE-PRESENT
- definition: student can point to evidence (text/visual/audio) for answers OR justify writing choices (purpose/audience/context).
- trigger: TRACE missing => FenceMode must be TRUNCATE or STITCH (no widening).
5.2 NIT (Narrative Irreversibility Threshold) — Writing collapse early warning
- SensorID: ENG-NIT-v0.1
- definition: once the story or argument commits to a wrong track, student cannot recover coherently.
- observed as: contradiction chain, character/goal drift, time-jumps, incoherent ending.
- trigger: NIT breached => STITCH (plot spine + paragraph chain + sentence control).
5.3 “False Competence” (Paper 2)
- SensorID: ENG-FALSECOMP-P2
- definition: MCQ ok but OE weak; student “recognises” but cannot produce/justify.
- trigger: enforce trace + OE drills + explanation ladder.
========================================================
6) FENCE™ PROTOCOL HOOKS (CONNECT YOUR EXISTING SYSTEM)
========================================================
Protocol naming:
SG×EDU×ENG×Z6×<Role>×Protocol×<PROT-ID>
Core protocols (attach to RootNodes):
- SG×EDU×ENG×Z6×Operator×Protocol×FENCE-TRACE-LADDER-v0.1
  target atoms: ENG-COMPREHENSION-* + ENG-VISUALTEXT-INFERENCE + ENG-LISTEN-*
- SG×EDU×ENG×Z6×Operator×Protocol×FENCE-WRITE-5BOX-v0.1
  target atoms: ENG-COHERENCE-PARAGRAPH-CHAIN + ENG-NIT-v0.1 + ENG-PURPOSE-AUDIENCE-REGISTER
- SG×EDU×ENG×Z6×Operator×Protocol×FENCE-GRAMMAR-IN-CONTEXT-v0.1
  target atoms: ENG-GRAMMAR-IN-CONTEXT + ENG-EDITING-ERROR-DETECT
- SG×EDU×ENG×Z6×Operator×Protocol×FENCE-ORAL-2PART-v0.1
  target atoms: ENG-READALOUD-* + ENG-SBC-*
========================================================
7) CONTINUITY BRIDGE — O-LEVEL ENGLISH (1184) (WHY THIS MAP SCALES)
========================================================
O-Level 1184 includes:
- Paper 2 reading comprehension with visuals + narrative/non-narrative texts + summary writing
- Paper 3 listening (note-taking style task)
- Paper 4 oral: planned response to video clip + spoken interaction :contentReference[oaicite:13]{index=13}
Bridge rule:
If Primary gates are P2-stable, secondary tasks become “bigger Z2 forms”, not new skills.
Primary → Secondary continuity is mainly:
- inference + effect,
- vocabulary in context,
- summary/synthesis,
- oral fluency + idea control.
========================================================
8) READY-TO-RUN DIAGNOSTIC PROMPT (PLUG INTO CAREEROS / EDUCATIONOS)
