jgrusewski f3cb0c78c2 docs(sp15): amend spec — 14 fixes from critical review

Critical review (combined fresh-eyes subagent + self-critique) flagged
14 issues. All addressed in this amendment.

CRITICAL (blocks implementation):
- §4.3 NEW: ISV slot allocation map [397..441) per phase, prevents
   parallel-dispatch ISV-table conflict (was: undefined, would break
   Approach B)
- §4.4 NEW: Phase 2A ↔ Phase 1.2 ABI contract (LobBar struct as
   canonical contract, Phase 2A defines first; Phase 1.2 conforms).
   Restores parallelism dependency
- §9.2 (3.5.4): plasticity injection now MANDATES cooldown engagement
   via PLASTICITY_WARM_BARS_REMAINING slot 438. NEW anchor test 2.22
   plasticity_cooldown_interlock prevents random-tail-output retrigger
   loop
- §9.2 (3.5.5): recovery curriculum replaced episode-level metadata
   (didn't exist in transition-level PER) with per-step DD_TRAJECTORY_
   DECREASING signal — same goal, no PER restructure

IMPORTANT (rework prevention):
- §9.2 (3.5.3): cooldown K threshold from running mean of per-trade
   PnL (NOT variance — variance is LOW during streaks, would delay
   cooldown when needed)
- §8.2 (3.5): Hold floor function form specified as bounded sigmoid
   with α/k/ε₀ ISV-driven; was "monotonic_inv_func" (undefined family)
- §6.2: cost kernel per-side semantics explicit. Half-spread × side_
   indicator at entry AND exit; commission_per_rt on close. Resolves
   round-trip vs per-side ambiguity
- §6.2: OFI impact λ initial value 2e-4 + ISV refit methodology;
   was "empirical fit from MES historical" (hand-wavy)
- §6.4: 8 baselines now mandate shared trunk forward; honest 15-25%
   overhead estimate (was 5-10%, optimistic)
- §12.3: Q9 burn policy explicitly honor-system, not enforcement.
   Mitigations described as deterrents not enforcement
- §10.6: Phase 4.5 thresholds CLI-config-driven with rationale,
   anchored empirically post-Phase-1 (was hardcoded > 1.0)

NIT:
- §9.2 (3.5.2): multiplier vs SP12 cap interaction explicit (applied
   BEFORE cap)
- §8.2 (3.1): α=0.7 hardcoded → ISV-driven from grad ratio (was
   feedback_isv_for_adaptive_bounds violation)
- §13: pearls reframed as candidates pending validation per discipline
   rule; pre-naming pressure removed

Test count: 21 → 22 (added 2.22). Phase 2 LOC: 2000 → 2100.
ISV_TOTAL_DIM: 396 → 441 post-SP15.

All 14 issues addressed in spec text. Ready for user review.
