T1 adds exactly ONE new state (resting GTX with TTL) and ONE new transition (TTL→cross) — both de-bugged in PINK production for a month — and inherits every truth/idempotency guarantee unchanged. No chase ⇒ no requote races. No advice ⇒ no clamp bugs. No book model ⇒ no misread books. The only new wire op is cancel-at-TTL, and cancel-INDETERMINATE is already law (§8). The bug surface is, by construction, the smallest nonzero one available. | FIRST SHIPPABLE INCREMENT — buildable immediately on unpark, pre-adjudication | | **T2** | Characterization-informed | L8 sweep findings become tactics: symbol-aware quantization/notional banding (§4-15), partial-remainder re-quote per urgency (§4-11), venue idiom law (§4-17), SNAPSHOT barrier (§4-19), latency decomposition telemetry (§4-18) | after T1 delta published | | **T3** | OB-aware placement | SmartPlacer adoption (L3): where-in-book offsets, `ob_confirms_signal`, conviction→patience (Q2 proxy), Appendix-E depth priors (validated) | gated on A1 adjudication | | **T4** | Full drive loop | PINK port complete (§7): chase budgets, requote gate, fill-vs-cancel races, exit escalation | the v1-spec vision |
