TENNISLOCKS v17.10.x – 3-SET SUPPRESSION FIX (SURGICAL PATCH)

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

READ THIS SECTION FIRST – AI EXECUTION INSTRUCTIONS

---

This is NOT a copy-paste patch file. This is a SURGICAL AUDIT INSTRUCTION SET.

Your AI assistant must:

1. LOAD the full script file (Tennislocks v17.10.0 line_mass_refactor_multichain_test_patched_updated)
2. SEARCH for each function/block by exact function name and comment markers
3. LOCATE the specific lines described in each patch instruction
4. VERIFY the current values match the "FIND" pattern before changing
5. APPLY the "REPLACE WITH" values exactly as specified
6. PRESERVE all surrounding code, comments, and whitespace
7. TEST one known 3-set match (Noskova–Gibson or similar) after each pass
8. FIX any undefined variable errors encountered during execution

DO NOT:

• Copy-paste from this instruction file into the script
• Make edits without verifying the current code first
• Skip verification steps
• Change anything not explicitly listed

---

PART A – ROOT CAUSE DIAGNOSIS

---

The 3-set suppression hitting 55–70% favorites is caused by 5 cascading layers:

1. Winner seed layer – Elo weight can stay too high (0.30 max) even when stats disagree, inflating the mismatch classification seed
2. Mismatch mapping – Floors too low (0.50–0.52), ranges too tight (0.33–0.35), so 65% favorites classified as "meaningful mismatch"
3. Set-2 taper – Soft thresholds all at 0.35, maxPen for CH is 0.120 (3x ATP), boost multipliers too high
4. SET_DELTA_MP sweep pressure – Boost gate starts at mismatch 0.15, ramps too fast
5. Totals-only tanking – 2-game trigger fires in totals mode with full mismatch scaling (1.2x multiplier)

Secondary layers (Markov trim, display blend) only need adjustment AFTER fixing the above.

Fix order: Winner seed → Mismatch floors → Taper knobs → Sweep pressure → Tanking → (Pass 2: Markov, if needed)

---

PART B – PASS 1 SURGICAL PATCHES

---

PATCH 1: Reduce Elo Leverage in Winner Seed

LOCATION: winnerEngineLayers() function, Elo weight calculation block

FIND: The section computing wE (Elo weight) with trust-based boosting

AUDIT STEPS:

1. Search for: var wE = THRESHOLDS.BLENDWELO
2. Locate the trust-boosting block: if (trustMinbl2 < blTrustGate)
3. Find the neutrality band compression block: if (Math.abs(pModelA - 0.50) < blNeutBand)

CURRENT BEHAVIOR:

• Default Elo weight can reach 0.30+ via trust boosting
• Even with disagreement, Elo can still dominate at 0.20–0.25
• This inflates pickTaperSeedA() median, triggering over-classification

CHANGES:

Change 1.1 – Default Elo Weight Cap

text
FIND:
var blEloCap = blIsWta ? 0.20 : (blIsCh ? 0.22 : 0.25)

REPLACE WITH:
var blEloCap = blIsWta ? 0.18 : (blIsCh ? 0.19 : 0.22)

Change 1.2 – Disagreement Penalty Enforcement

text
FIND (inside neutrality compression block):
var targetE = Math.min(wE, 0.05)

REPLACE WITH:
var targetE = Math.min(wE, 0.03)

Change 1.3 – Add Hard Elo Cap After All Branches

text
FIND (after all wE calculations, before final weight normalization):
var wSum = wM + wS + wE + wFmp

INSERT BEFORE wSum line:
// Hard Elo cap – prevent trust branch from inflating taper seed
wE = Math.min(wE, 0.22)

EXPECTED RESULT: Elo weight capped at 0.22 max, drops to 0.10 with one disagreement, 0.03 with two+. Reduces false mismatch classification for 64–68% favorites.

---

PATCH 2: Re-Center Mismatch Mapping

LOCATION: mismatchIdxFromSeeds() function, floor/range calculation block

FIND: Lines defining miFloor and miRange for each tour

CURRENT VALUES:

text
var miFloor = miIsWta ? 0.50 : (miIsCh ? 0.51 : (miIsItf ? 0.51 : 0.52))
var miRange = miIsWta ? 0.33 : (miIsCh ? 0.34 : (miIsItf ? 0.35 : 0.34))

PROBLEM: 65% favorite maps to mismatchIdx ≈ 0.44 (above soft threshold 0.35)

REPLACE WITH:

javascript
var miFloor = miIsWta ? 0.56 : (miIsCh ? 0.59 : (miIsItf ? 0.58 : 0.58))
var miRange = miIsWta ? 0.32 : (miIsCh ? 0.31 : (miIsItf ? 0.32 : 0.30))

EXPECTED RESULT:

• 65% favorite → mismatchIdx ≈ 0.28 (below soft threshold)
• 70% favorite → mismatchIdx ≈ 0.47 (moderate)
• 78%+ favorites → Still classified as true mismatches

---

PATCH 3: Soften Set-2 Taper (Multi-Step)

LOCATION: taperParamsForTour() function return statements for each tour

AUDIT: Find the return blocks for ATP, WTA, CH, ITF tours

Change 3.1 – Raise Soft Thresholds

FIND:

javascript
var TAPERSET2SOFTTHRESHOLDATP = 0.35
var TAPERSET2SOFTTHRESHOLDCH = 0.35
var TAPERSET2SOFTTHRESHOLDITF = 0.35
var TAPERSET2SOFTTHRESHOLDWTA = 0.35

REPLACE WITH:

javascript
var TAPERSET2SOFTTHRESHOLDATP = 0.45
var TAPERSET2SOFTTHRESHOLDCH = 0.48
var TAPERSET2SOFTTHRESHOLDITF = 0.46
var TAPERSET2SOFTTHRESHOLDWTA = 0.43

Change 3.2 – Reduce Max Penalties (CRITICAL for CH/ITF)

FIND:

javascript
var TAPERMAXHOLDPENATP = 0.036
var TAPERMAXHOLDPENCH = 0.120
var TAPERMAXHOLDPENITF = 0.054
var TAPERMAXHOLDPENWTA = 0.039

REPLACE WITH:

javascript
var TAPERMAXHOLDPENATP = 0.032
var TAPERMAXHOLDPENCH = 0.075
var TAPERMAXHOLDPENITF = 0.045
var TAPERMAXHOLDPENWTA = 0.035

JUSTIFICATION: CH penalty was 3.3x ATP (0.120 vs 0.036) – this is the single biggest over-suppression source in Challenger matches.

Change 3.3 – Reduce Boost Multipliers

FIND:

javascript
var TAPERMAXPENBOOSTATP = 0.35
var TAPERMAXPENBOOSTCH = 0.70
var TAPERMAXPENBOOSTITF = 0.70
var TAPERMAXPENBOOSTWTA = 0.45

REPLACE WITH:

javascript
var TAPERMAXPENBOOSTATP = 0.25
var TAPERMAXPENBOOSTCH = 0.35
var TAPERMAXPENBOOSTITF = 0.40
var TAPERMAXPENBOOSTWTA = 0.30

EXPECTED RESULT: Set-2 taper now gentle for 55–72% favorites, only aggressive above 75%+. CH/ITF suppression reduced by ~40%.

---

PATCH 4: Delay SET_DELTA_MP Activation

LOCATION: runMatchSimulationExact() function, SET_DELTA_MP calculation block

FIND: The section computing SET_DELTA_MP with mismatch-based increases

CURRENT LOGIC: Boost starts at mismatchIdx >= 0.15

CHANGES:

Change 4.1 – Raise Boost Gate

text
FIND:
if (mismatchIdx > 0.15) {

REPLACE WITH:
if (mismatchIdx > 0.40) {

Change 4.2 – Reduce Boost Slope

text
FIND (inside the boost calculation):
SET_DELTA_MP += ... * (mismatchIdx - 0.15) * ...

REPLACE WITH:
SET_DELTA_MP += ... * (mismatchIdx - 0.40) * 0.65

NOTE: The exact multiplication factor depends on your current code structure. Apply 0.65x scaling to whatever multiplier currently exists.

EXPECTED RESULT: Sweep pressure only activates for 73%+ favorites, ramps slower. Normal 65% favorites get zero sweep bias.

---

PATCH 5: Totals-Only Tanking Suppression

LOCATION: runMatchSimulationExact() function, tanking/blowout logic block

FIND: The section applying tanking penalties when setDiff >= tankTrigger

CHANGES:

Change 5.1 – Add Totals-Only Mismatch Gate

text
FIND:
if (setDiff >= tankTrigger) {

REPLACE WITH:
// Totals-only mode: require much higher mismatch for 2-game trigger
var tankMismatchGate = (opts && opts.totalsOnly) ? 0.70 : 0.50
var allowTanking = (mIdx2 >= tankMismatchGate) || (setDiff >= 3)

if (allowTanking && setDiff >= tankTrigger) {

Change 5.2 – Reduce Mismatch Scaling in Totals Mode

text
FIND (inside tanking penalty calculation):
basePenalty = basePenalty * (1 + 1.2 * mIdx2)

REPLACE WITH:
var tankMismatchMult = (opts && opts.totalsOnly) ? 0.6 : 1.2
basePenalty = basePenalty * (1 + tankMismatchMult * mIdx2)

EXPECTED RESULT: Totals-only sims don't snowball into blowouts unless mismatch is extreme (70%+) or set deficit is 3+ games.

---

PART C – UNDEFINED VARIABLE FIX

---

INSTRUCTION: During execution, if you encounter ReferenceError: [variable] is not defined:

1. Search for the variable name in the entire script
2. Check if it's:
   • Misspelled (e.g., opts.totalsOnly vs totalsOnly)
   • Defined in wrong scope (function vs global)
   • Missing declaration (var, let, or function parameter)
3. Common culprits in this script:
   • opts parameter not passed to nested functions
   • tourLabel vs tourLabelMaybe inconsistency
   • mismatchIdx vs mIdx vs mIdx2 naming variants

FIX PATTERN:

javascript
// If function uses opts.totalsOnly but opts not passed:
FIND:
function myFunction(hA, hB) {
    if (opts.totalsOnly) { ... }

REPLACE WITH:
function myFunction(hA, hB, opts) {
    if (opts && opts.totalsOnly) { ... }

// Then find all callers and add opts parameter

---

PART D – VALIDATION PROTOCOL

---

After each patch pass, run this test:

Test Match: Noskova (67% favorite) vs Gibson, ATP hard court, BO3

Expected Values After Pass 1:

Metric	Before Fix	After Pass 1	After Pass 2 (if needed)
Mismatch Index	0.44	0.33	0.33
Raw MC P3	35%	41%	42%
Markov Adj P3	28%	37%	38%
Display P3	26%	36%	38%
Set-2 Loser Hold Penalty	4.1%	2.8%	2.8%
SET_DELTA_MP Boost	0.008	0	0

Pass/Fail Criteria:

• ✅ PASS if Display P3 is 35–40% for 67% favorite
• ❌ FAIL if Display P3 still below 33%
• ⚠️ CAUTION if Display P3 above 43% (may have over-corrected)

If Pass 1 achieves 35–40% display P3, STOP. Do not proceed to Markov/display patches.

---

PART E – PASS 2 (ONLY IF NEEDED)

---

TRIGGER: If after Pass 1, Display P3 for 67% favorite is still below 33%

PATCH 6: Soften Markov Compression

LOCATION: Lines computing p3AdjMP or p3setAdj via Markov adjustment

FIND: Mismatch compression coefficients

CURRENT:

javascript
var mpMmC = mpTK === 'WTA' ? 0.20 : (mpTK === 'CH' ? 0.18 : 0.16)
var mpClP = mpTK === 'WTA' ? 0.03 : (mpTK === 'CH' ? 0.028 : 0.025)

REPLACE WITH:

javascript
var mpMmC = mpTK === 'WTA' ? 0.12 : (mpTK === 'CH' ? 0.11 : 0.10)
var mpClP = mpTK === 'WTA' ? 0.015 : (mpTK === 'CH' ? 0.012 : 0.012)

Add Conditional Gate:

javascript
// Only compress if mismatch is high OR Markov raw >> MC raw
var shouldCompress = (mmMP > 0.60) || (pDecRawMP > p3setRaw + 0.03)
if (!shouldCompress) {
    p3AdjMP = pDecRawMP  // Skip compression
}

---

PART F – FINAL CHECKLIST

---

Before marking this patch complete:

• All 5 Pass 1 patches applied and verified
• undefined errors fixed
• Test match run successfully
• Display P3 for 67% favorite is 35–40%
• UNDER picks still intact (no side-effect bias flip)
• Script executes without errors
• Logged output includes: mismatchIdx, SET_DELTA_MP, raw pDecider, Set-2 taper penalty, Markov adj p3, display p3

COMPLETION SIGNATURE:

=== TENNISLOCKS v17.10.x 3-SET SUPPRESSION FIX APPLIED ===
Date: [INSERT DATE]
Patches Applied: 1.1-1.3, 2, 3.1-3.3, 4.1-4.2, 5.1-5.2
Pass 2 Needed: [YES/NO]

---

EMERGENCY ROLLBACK INSTRUCTIONS

---

If the fix breaks the script or over-corrects:

1. Restore from backup before patch application
2. Apply only Patches 2 and 3 (mismatch floors + taper)
3. Skip Patches 1, 4, 5 on first attempt
4. Re-test and report which layer still overfires

DO NOT blindly revert all changes – the CH taper penalty (Patch 3.2) is objectively broken at 0.120 and must be fixed regardless.
