# P3-S.9 CONSOLIDATED REPAIR PLAN — SNIPERGOLD_ML

```text
Date       : 2026-08-22
Session    : P3-S.9 — Consolidated Architecture & Repair-Design Review
Status     : REPAIR SPECIFICATION ONLY. NOT implemented. No production change.
Purpose    : Classify every known issue (RETAIN/REPAIR/REDESIGN/DEPRECATE/
             DOCUMENT ONLY) so the future implementation phase patches ONE
             architecture (Option A, docs/P3_S9_ARCHITECTURE_REVIEW.md) and
             never N files independently.
Priorities : P1 Correctness -> P2 Architecture -> P3 Documentation/cleanup.
Human verification : CANCELLED.
```

## 2. REPAIR FAMILIES (implementation units for the future phase)

```text
FAMILY 1 — EVENT/STATE contract (fixes A, C, D, J):
  BUG-P3S2-001, BUG-P3S3-001, D-12. Adds validity windows + supersession
  for sweep/CHoCH events; f9/f18 consumers read events, not raw states.

FAMILY 2 — ZONE contract (fixes B, D):
  BUG-P3S4-001/-002, BUG-P3S5-001. Mitigation-aware, timing-unified,
  invalidation-aware zone consumption in Engine 2 (C/E agents).

FAMILY 3 — SETUP LAYER (fixes F, I, J; the core of Option A):
  D-8, D-9, D-10, D-11, D-1 (aggregator re-scope). Setup entity with
  identity (G), lifecycle (H), M15 chain consumer, H4/M30 context gates.

FAMILY 4 — MTF/TRAINING ALIGNMENT (fixes E, G, H):
  D-2, D-3, D-5, D-6, BUG-P3S2-003, BUG-P3S3-002. Canonical MTF model,
  conflict policy, slot->TF enforcement, training/runtime pivot semantics.

FAMILY 5 — DISPLAY/CONTRACT (fixes F display side):
  D-4. Render the setup entity; draw H4/M30 structures; align the
  "TRADE SETUP" panel with the setup layer.

FAMILY 6 — CANONICAL DEFINITIONS / CLEANUP (fixes E, P3):
  BUG-P3S5-002/-003/-004, BUG-P3S6-001, BUG-P3S2-004/-005, BUG-P3S3-003,
  BUG-P3S4-003/-004, D-7, D-14. Adjudicate definitions; document;
  deprecate legacy semantics to reference.
```

## 3. REPAIR PRIORITIES

### Priority 1 — Correctness (stale state, wrong mitigation, lifecycle, future leakage, runtime/training mismatch)

```text
BUG-P3S2-001, BUG-P3S3-001, BUG-P3S2-003, BUG-P3S3-002,
BUG-P3S4-001, BUG-P3S4-002, BUG-P3S5-001, D-9, D-11, D-12
-> FAMILY 1 + FAMILY 2 + (D-9/D-11 setup-predicate exposure)
```

### Priority 2 — Architecture (setup identity, MTF hierarchy, primitive relationships, canonical definitions)

```text
D-1, D-2, D-3, D-4, D-5, D-6, D-8, D-10, D-13,
BUG-P3S5-002, BUG-P3S5-004, BUG-P3S6-001
-> FAMILY 3 + FAMILY 4 + FAMILY 5 (after owner adjudication of OD-1..OD-5)
```

### Priority 3 — Documentation/cleanup (terminology, legacy comments, duplicate specs)

```text
BUG-P3S2-004/-005, BUG-P3S3-003, BUG-P3S4-003/-004,
BUG-P3S5-003, D-7, D-14
-> FAMILY 6
```

---

## 4. IMPLEMENTATION ORDER (for the future phase — NOT executed)

```text
Step 0 : Owner adjudication of OD-1..OD-5 (architecture lock).
Step 1 : Tests first — extend P3-S.2/S.3/S.4/S.5/S.8 synthetic suites to
         assert the new contracts (f9/f18 expiry, zone mitigation, setup
         identity/lifecycle).
Step 2 : FAMILY 1 (EVENT contract) — one repair family at a time.
Step 3 : FAMILY 2 (ZONE contract).
Step 4 : FAMILY 3 (SETUP LAYER, Option A) + aggregator re-scope.
Step 5 : FAMILY 4 (MTF/training alignment).
Step 6 : FAMILY 5 (display) + FAMILY 6 (definitions/cleanup).
Step 7 : Regression (Engine 1/2/3 unit tests), parity (SB-06 class),
         setup dataset rebuild; preserve historical evidence
         (immutable checkpoints; P3-S.2 §13 rule).
```

## 5. EXPLICIT NON-GOALS (this plan does NOT authorize)

```text
- No AUC/PF/profit-based selection of any repair or constant.
- No human annotation restart.
- No ML retraining / parameter optimization.
- No restoring legacy v4.x code as-is (semantics extracted only).
- No "best of both" grab-bag (brief §21).

## 9. P3-S.10 ADDENDUM — OWNER ADJUDICATION COMPLETE (2026-08-22)

```text
Step 0 of §4 (Owner adjudication of OD-1..OD-5 — architecture lock) is now
COMPLETE. The historical body of this plan (§1-§5) is UNCHANGED. This
addendum records only the adjudicated outcomes that finalize the plan's
open design-decision items. Authority: docs/P3_S10_OWNER_ADJUDICATION.md;
frozen contract: docs/SNIPERGOLD_CANONICAL_SETUP_CONTRACT_v1.md.

OD-1 (H4/M30 gate policy)  = YES — H4 AND M30 are hard direction-compatible
  context gates for Candidate Setup formation; conflict/neutral -> NO
  CANDIDATE SETUP. Overrides P3-S.7 S-N/S-C FOR THE SETUP LAYER ONLY.
  SIGNAL != CANDIDATE SETUP (H4-only/M30-only/M15-only signals may exist).
OD-2 (Canonical MTF model) = H4/M30/M15/M3 (runtime/setup); D1/H4/H1/M15 =
  legacy/current training semantics, UNCHANGED; F4 alignment requirement
  recorded. -> finalizes D-5/D-6.
OD-3 (Validity windows)    = SEMANTIC CONTRACT per primitive; W_sweep = 40
  (justified), W_choch = 40 (justified), zone age = none by semantics;
  W_setup / W_m3 / W_zone_age = OPEN NUMERIC PARAMETERS (never from
  performance). -> finalizes the "split per stage" row of §J.
OD-4 (MTF conflict policy) = GATE-FAIL for the setup layer (H4<->M30 ->
  BLOCKED; M15 vs H4/M30 -> BLOCKED; M3 contrary -> micro-score only;
  no arithmetic voting). Aggregator = scoring layer. -> finalizes D-2/D-13.
OD-5 (Canonical OB)        = A — OB "strong move" (1.5x avg) is the
  intentional simpler proxy for Displacement (1.6x); OB requires NO
  displacement and NO BOS/CHoCH (redundant with the chain's CHoCH stage;
  legacy structure-break definition = historical). 1.5/1.6 kept and
  documented. -> finalizes BUG-P3S5-002 (canonical current confirmed,
  DOCUMENT ONLY) and BUG-P3S6-001 (DOCUMENT ONLY, F6).

Master classification deltas (classification column only, per OD):
  BUG-P3S5-002 : DESIGN DECISION -> DOCUMENT ONLY (OD-5; canonical current
                 definition confirmed; legacy structure-break = historical).
  BUG-P3S6-001 : DESIGN DECISION -> DOCUMENT ONLY (OD-5; constants kept
                 separate; roles documented).
  D-2, D-13    : REDESIGN -> RESOLVED (OD-4 policy defined; implementation
                 remains F4).
  D-5, D-6     : REDESIGN/DEPRECATE -> RESOLVED (OD-2 model frozen;
                 implementation remains F4).
  D-8          : REDESIGN -> RESOLVED (frozen contract §A/§D; implementation
                 remains F3).
  OD-3 windows : per-primitive semantic contract frozen; OPEN NUMERIC
                 PARAMETERS recorded (§5 of P3_S10_REPAIR_IMPLEMENTATION_SPEC.md).

ARCHITECTURE STATUS (post-adjudication): READY FOR REPAIR.
Next: P3-S.11 — F1 EVENT CONTRACT REPAIR (separate implementation session,
tests first, one family at a time).
