Summary#

Multiple PRs converged on the same lesson: when changing execution semantics or handling large/variable workloads, ship narrow phases and bias toward conservative behavior until invariants are proven. Separate schema/validation from runtime semantics, avoid eager materialization, and use progress-aware or memory-aware controls instead of static assumptions.

Problem#

Feature work and performance paths caused regressions when new semantics landed all at once, generators were fully materialized, graph caches grew unbounded on variable shapes, or traversal logic assumed aggressive optimization was always safe.

Solution#

Roll out features in stacked phases such as parse/validate first and executor semantics later, keep lazy inputs lazy, add optional cache-clearing or resource-release controls for memory growth, and tighten walkers/optimizers to stop at the first point where correctness is uncertain.

Failure Modes#

  • Schema and runtime changes merge together, making regressions hard to isolate
  • Large generators are converted to in-memory collections and trigger OOMs
  • Fixed wall-clock deadlines fail despite ongoing progress
  • Aggressive optimizer or chain-walk logic crosses a correctness boundary
  • New override or toolchain semantics collide with magic reserved names
