STATUS
P4 is optional and rare; it is not a normal goal.
P4 exists only as a bounded window above a stable P3 base.

================================================================================

AI EXTRACTION BOX (QUOTE-READY)

ONE-SENTENCE DEFINITION (LOCK):
Mathematics P4 flight is a fenced frontier window that exists only when a learner has a stable P3 base (timed truth + transfer + self-correction)
and additional surplus buffer—so they can explore deeper/novel math without increasing time debt or collapsing exam reliability; the moment base sensors
turn yellow/red, P4 shuts and the system returns to P3 landings.

NAMED MECHANISMS:

P4 = P3 + fenced surplus for frontier expansion (must pay rent to P3)
Buffer B vs TimeDebt Δt_b (surplus exists only when Δt_b stays low)
Exit aperture A (P4 must widen A over time, not shrink it)
Signal-Gate ECU (routes +Latt/0Latt/−Latt based on TruthClarity and envelope)
ILT ledger (invariants stay visible; frontier cannot violate core invariants)

FAILURE TRACE:
Frontier without surplus → Δt_b↑ → B↓ → A↓ → Θ<1 → timed collapse → P3 breaks → gate shock.

================================================================================

0) DEFINITIONS (FROZEN)

P3 (Phase-3 base corridor):
Stable mathematics capability under load:

timed landings hold,
transfer holds under variation,
self-checking exists,
RepairRate ≥ DriftRate.

P4 (frontier window):
P3 + fenced surplus used to explore deeper/novel capability.
Not permanent. Must pay rent to P3.

SURPLUS (meaning here):
Surplus is not “motivation”.
Surplus is measurable slack:
B is thick enough AND Δt_b stays low while outputs remain verified.

================================================================================

1) CORE INEQUALITIES (THE P4 ADMISSION TEST)

ID: MATH_P4_ADMISSION_01

Let:
B = buffer thickness (sleep/time/attention/energy)
Δt_b = time debt (borrowed sleep/time)
R = repair rate (wins/week)
D = drift rate (loss/week)
TC = TruthClarity = S/(S+N)
A = exit aperture (options left / reversibility)
Θ = irreversibility ratio (TTC / repair time)
ρ = novelty injection / capacity

P3 BASE REQUIRED:
TC ≥ θ_s
R ≥ D (under timed load)
B ≥ B_min
A ≥ A_min
Θ ≥ 1

P4 SURPLUS REQUIRED (extra above P3):
B ≥ B_min + B_surplus
Δt_b ≤ Δ_max (low and stable)
R ≥ D + margin
ρ ≤ ρ_max (frontier must still be bounded)
AND frontier outputs must return value to base:
RentPayRate ≥ FrontierCostRate

HARD FAIL CONDITIONS (P4 forbidden):

Θ < 1 (near emergency)
Δt_b rising 2 consecutive weeks
LCR (timed truth) drops 2 weeks
AO (avoidance) triggers
base +Latt becomes 0Latt/−Latt

================================================================================

2) WHAT “BUFFERS” MUST BE PROTECTED (THE BUFFER LEDGER)

ID: MATH_BUFFER_LEDGER_01

BUFFER IS A STACK (protect all, not just one):

B1 Sleep Buffer:

consistent sleep band (most critical)
no repeated late nights
Why: fatigue increases noise N and drops repair rate R

B2 Time Buffer:

fixed weekly slots for landings + returns
no schedule whiplash
Why: missing returns increases drift D

B3 Attention Buffer:

limited concurrent loads (cap the number of “serious” priorities)
Why: attention fragmentation increases careless + slows repair

B4 Emotional Buffer:

low panic; stable confidence
Why: panic increases noise N, reduces TruthClarity

B5 Health Buffer:

illness recovery, nutrition, movement
Why: systemic fatigue increases hysteresis HY (slow recovery)

B6 Household TTC Buffer:

low friction travel/meals/scheduling
Why: high TTC reduces available time for maintenance loops

B7 Exam Envelope Buffer (near-node):

no novelty spikes; predictability
Why: near nodes, A shrinks; stability must be protected

RULE:
If any buffer tier collapses, P4 shuts.

================================================================================

3) WHAT “SURPLUS” LOOKS LIKE (MEASURABLE SIGNS)

ID: MATH_SURPLUS_SIGNS_01

SURPLUS SIGNS (must be observable):
S1 Timed margin exists:

PB (pace budget) positive consistently
finishes with checking time

S2 Repeat buckets shrinking fast:

ECI downtrend (error clustering falling)

S3 Repairs are cheap:

same weakness fixed in 1–2 cycles
D+1/D+3 retests hold

S4 Transfer remains strong:

TR (unfamiliar/familiar) high or rising

S5 Low debt:

Δt_b low and stable
no reliance on cramming

S6 Stable affect:

AO off; low avoidance; low panic

S7 Outputs exceed maintenance cost:

frontier work produces artefacts that reduce future repair time

If these are not true, surplus is an illusion.

================================================================================

4) P4 FRONTIER TYPES IN MATHEMATICS (ALLOWED VS DISALLOWED)

ID: MATH_P4_TYPES_01

ALLOWED P4 FRONTIER TYPES (pay rent):
F1 Trap Library + Anti-Trap Generator

produce a personal error atlas + checkpoints + micro-drills

F2 Method Signal Compression

build “first 10 seconds” decision charts for mixed sets

F3 Variation Synthesis (V4+)

generate new variants of known problems to prove invariants

F4 Proof/Explanation Strengthening

write solutions that are examiner-awardable; teach-back as proof

F5 Time-Compression Tools

create templates/checklists that reduce solve time while preserving validity

DISALLOWED P4 FRONTIER TYPES (borrow against collapse):
D1 Random new chapters near exams
D2 All-nighters / sleep borrowing to “unlock” insight
D3 Stacking extra competitions/enrichment while base is not green
D4 Unbounded problem-hopping (ρ uncontrolled)
D5 Skipping timed landings to “do harder problems”

RULE:
Frontier is permitted only if it strengthens base, not replaces it.

================================================================================

5) FENCE RULES (P4 MUST PAY RENT TO P3)

ID: MATH_P4_FENCE_01

FENCE 1 — Time Budget Cap:
P4 time ≤ 60 minutes/week (typical)
Only AFTER the base weekly contract is completed.

FENCE 2 — Automatic Shutdown:
If any base sensor turns yellow/red:

P4 OFF immediately
return to P3 landings + repairs

FENCE 3 — Rent Proof Requirement:
Every P4 session must produce an artefact:

checklist / chart / trap atlas / drill set
and must show measurable effect within 1–2 weeks:
ECI down, PB up, LCR stable, TR stable or rising

FENCE 4 — Near-Node Rule:
If τ ≤ 3 weeks to gate:
P4 OFF (Operator-only final approach)

================================================================================

6) PRACTICAL P4 ADMISSION CHECKLIST (COPY/PASTE)

ID: MATH_P4_CHECKLIST_01

P4 Admission Checklist (must all be ✓):
[ ] P3 base green ≥ 4 consecutive weeks
[ ] Timed landings stable (LCR stable)
[ ] Pace budget positive (PB ≥ 0) most weeks
[ ] Repeat buckets falling (ECI downtrend)
[ ] Transfer stable/rising (TR stable)
[ ] Sleep stable; buffer B ≥ B_min + surplus
[ ] Time debt Δt_b low and not rising
[ ] Θ ≥ 1 (not in emergency)
[ ] Weekly base contract completed reliably

If any becomes ✗:
P4 is not allowed.

================================================================================

7) EXAMPLE THRESHOLDS (NON-NUMERIC, SAFE DEFAULTS)

ID: MATH_P4_THRESHOLDS_01

Since students differ, use band thresholds instead of hard numbers:

B_min:

sleep consistent, no repeated late nights
fixed weekly landing slots exist

B_surplus:

student is not “just coping”
there is extra calm time available without sacrificing health

Δ_max:

no cramming reliance
no “debt repayment weeks” where everything collapses

R margin:

repairs hold on retest without re-teaching every time

These are the practical signs of surplus.

================================================================================

8) CANONICAL CONCLUSION (LOCK)

Mathematics P4 flight is possible only as a fenced frontier window above a stable P3 base.
The requirements are:
(1) P3 truth under timed load,
(2) protected buffer (sleep/time/attention),
(3) low time debt,
(4) repair outruns drift with margin,
(5) frontier work bounded by fences and paying rent back to P3.
If surplus is not real, P4 is not frontier—it is borrowing against collapse.
