docs: v1.9.0 release notes draft (Premium-A shipping milestone)#185
Merged
Conversation
Preemptive draft for v1.9.0 — ready for ship-trigger after audit clears. Covers the Premium-A blueprint shipping milestone: - 27 precomputed preflop blueprint shards (PR #171 + asset commit 1783bef): 169-class engine 178x/406x/448x speedup; ~21 MB bundle shipped under assets/blueprints/. - Blueprint loader API (PR #174), stack-depth interpolation (PR #173), postflop subgame wiring (PR #177), top-level SolverRouter (PR #181), UI integration (PR #178). - Vector-form BR walk (PR #170): W2.3 strict-PASS, persona table 17/0/0/0 (recorded in PR #184). - CS-bug fix (PR #165): preflop State::initial honors config.initial_contributions. - B10 per-combo frequency train (PRs #149/#154/#158/#160): W2.2 Sarah Range.diff -> PASS. - DCFR optimization ledger (docs/rust_optimization_ledger.md): empirical speedups for PRs #114/#139/#150/#157/#162/#170/#171. Known limitations disclosed honestly: - Flop live-solve OOMs in v1.9.0; flop = blueprint-only. v1.10 task #70 addresses (docs/v1_10_postflop_optimization_plan.md). - top_k_per_side is a speed knob, not a correctness flag. - "Realtime postflop" claim scoped precisely: turn + river only.
