Summary OS (Standalone Canonical Page) — Almost-Code + V1.1 (Paste-Ready)

Summary_OS := a compression-and-paraphrase system that produces
word-limited output while preserving:
  required points + meaning integrity + logical relations,
under strict constraints (word limit + time).

P3(Summary) = student can consistently:
  - capture required points
  - paraphrase (not copy)
  - obey word limit
  - avoid meaning leakage
across varied passages.

A summary is not “short writing”.
It is information selection + compression + paraphrase control.

Summary_OS {
  Input:
    - passage segment(s)
    - question/task requirements (what counts as a point)
  Process:
    1) Point Extraction (no paraphrase yet)
    2) Point Compression (merge/reduce)
    3) Paraphrase (synonym families + structure change)
    4) Integrity Check (meaning preserved)
    5) Word Limit Trim (remove redundancy safely)
  ControlLayer:
    - anti-copy rule
    - evidence discipline
    - time boxing
  Output:
    - concise accurate summary within word limit
}

P0: cannot identify points; copies randomly
P1: identifies some points but misses many; heavy copying
P2: can summarise but often exceeds word limit or leaks meaning
P3: consistent point capture + clean paraphrase + within word limit

FM1: Missed points (selection failure)
FM2: Meaning leakage (distortion)
FM3: Copying chunks from passage (paraphrase failure)
FM4: Word limit breach (control failure)
FM5: Repetition / redundancy (compression failure)
FM6: Wrong linking logic (cause/effect, contrast lost)

SUM_Sensors {
  PointsCaptured / PointsRequired
  MeaningLeakEvents (count)
  CopyRate (how much is lifted directly)
  WordLimitCompliance (Y/N)
  RepetitionRate
  LogicPreservationScore (relations kept)
}

Proxies {
  - count required points present (tick checklist)
  - underline copied phrases (copy rate proxy)
  - circle distortions/overclaims (leak proxy)
  - count redundant phrases (repetition proxy)
}

TIME_BOX_SUMMARY {
  Extract points: 30–40%
  Write summary: 40–50%
  Trim/check: 10–20%
}

No sentence should be copied verbatim.
Change at least one of:
  - word choice
  - sentence structure
  - point order
while preserving meaning.

Do not add new ideas.
Do not exaggerate.
Do not remove required points.

POINT_LIST := list required points as short bullet fragments.
No full sentences.
No “nice writing”.
Just content.

Merge related points:
  two bullets → one clause
Remove examples/details unless required.
Keep relations: because/however/therefore.

Use:
  - synonym families
  - collocation swaps
  - structure swaps (active↔passive, clause merge)
Avoid:
  - “synonym substitution” that changes meaning

Check:
  - all required points present?
  - any distortion?
  - any over-claims?

Trim redundancy first.
Replace long phrases with compact equivalents.
Remove repeated framing.

LOOP_POINTS {
  read passage
  list 6–10 points as fragments
  compare to answer key checklist
  fix missed point pattern
}

LOOP_COMPRESSION {
  take 8 points
  compress to 5 sentences max
  preserve relations (cause/contrast)
}

LOOP_PARAPHRASE {
  for each key phrase:
    create 2 alternatives with same meaning
  test:
    can you paraphrase without meaning drift?
}

LOOP_TRIM {
  write summary
  cut 10–15% words without losing points
  remove redundancy
  tighten connectors
}

Summary requires paraphrase families.
Paraphrase families require P3 vocabulary + chunk control.

Student writes “nice sentences”
→ forgets to extract points
→ exceeds word limit
→ copies phrases to save time
→ misses required points
→ summary score stays low

Summary improves by:
  point extraction first → controlled compression → paraphrase → trim.
Not by writing “better English”.

SUMMARY_OS_SPEC v1.0 {
  Definition: compression + paraphrase + integrity under word limit
  Steps: extract points → compress → paraphrase → integrity check → trim
  Sensors: points captured, meaning leakage, copy rate, word limit, repetition
  Repairs: point drill, compression drill, paraphrase families, trim drill
  P3 Gate: required points present + no leakage + within word limit
