Cold §22 forecast measured ~215-233s on prod: §9.x layers re-execute the same horizon/segment-invariant DB loads with identical args hundreds of times per report (profiled: get_competitors x69, market_metrics x124, get_monthly_macro x290). Add a per-report ContextVar cache (forecast_cache(), opened once in the orchestrator) + @cached(key_builder) on the expensive §9.x loaders so each unique load runs ONCE and reuses the same frozen, read-only instance. Output is byte-identical (memoized producers are frozen dataclasses / read-only Pydantic, callers never mutate; cache is per-report, discarded on exit; no-op outside the report build). No concurrency, no signature changes. - forecast_request_cache.py: ContextVar cache + cached() decorator (no-op outside context, reentrant, _MISS sentinel for cached None) - @cached on competitors/future_supply/market_metrics/macro_series/ sales_series/macro_coefficient/demand_normalization/regression loaders - orchestrator: wrap build_site_finder_report in forecast_cache() - 58 tests: key discrimination (call-counting regression guard), no-op-outside, per-report isolation, reentrancy, frozen-producer canary, amplification proof (real get_monthly_macro xN->1) code-reviewer APPROVE (keys correct, mutation-safe, output identical). 1265 forecast/cache tests green. No new deps. Refs #1129. |
