Release Notes
Added
- Policy warm-start and resume-from-checkpoint -- Training can now load a
prior policy checkpoint and either warm-start (inject cuts into a fresh FCF)
or resume (continue from the saved iteration). Configured via
policy.mode: "fresh", "warm_start", or "resume".
- Simulation-only mode -- Run simulation against a saved policy without
re-training. Enabled when training.enabled = false with a valid policy.
- Truncation-with-penalty inflow method -- Combined truncation and penalty
enforcement for inflow non-negativity, matching SPTcpp's
truncamento_penalizacao mode. Configured via
modeling.inflow_non_negativity.method = "truncation_with_penalty".
- Per-plant inflow penalty via cascade -- Inflow non-negativity penalty
cost can now be overridden per hydro plant through the penalty cascade
(penalties.json hydro overrides → inflow_nonnegativity_cost).
- Bidirectional withdrawal and evaporation slacks -- Withdrawal and
evaporation violation slacks are now split into directional (pos/neg)
components with independent costs, enabling asymmetric penalisation.
- Per-block operational violations -- Min/max outflow, turbined flow, and
generation constraints now have per-block slack columns with independent
penalty costs.
- Cost decomposition -- Simulation output now includes 6 granular violation
cost columns (outflow_violation_below_cost, outflow_violation_above_cost,
turbined_violation_cost, generation_violation_cost,
evaporation_violation_cost, withdrawal_violation_cost) alongside the
aggregate hydro_violation_cost.
- Per-stage productivity override --
hydro_production_models.json can now
override the generation model for specific hydros at specific stages,
validated via the D24 regression test.
- Deterministic regression tests D19--D24 covering multi-hydro PAR(p),
operational violations, min-outflow regression, per-block violations,
bidirectional withdrawal, and productivity override.
Fixed
- LP bus balance productivity -- Constant-productivity hydros now use the
resolved per-stage production model (accounting for hydro_production_models
overrides) instead of the static entity model. Fixes incorrect load-balance
coefficients when per-stage overrides are active.
- Withdrawal cost extraction --
compute_cost_result now sums both
withdrawal_slack_neg and withdrawal_slack_pos, fixing understated
withdrawal violation costs in simulation output.
- Pre-study stage handling in estimation -- PAR(p) estimation pipeline
correctly handles pre-study stages with season fallback for lag statistics.
Changed
policy.mode is now a validated enum -- Invalid values (typos like
"warmstart") are rejected at config parse time with a clear error message
listing valid options, instead of silently defaulting to fresh training.
