Profile source capture, Nix evaluation/realization, resource/query checking,
and implementation builds without putting timings into immutable outputs.
Keep modular repositories; bound independent capture work, snapshot jj once
per observation, and retain final concurrent-edit and Git completeness checks.
Compose exact resource/closure/frontend/toolchain checks as memoized Nix
derivations. Preserve whole-workspace validation and the full compiler path
when no checked dependency is supplied. Share canonical Nixpkgs by content,
index workspace build contexts once, and narrow lock/driver/compiler inputs
with conservative complete-source fallback. Batch React witness checks only
when distinct source closures cannot share ambient declarations; otherwise
run the original independent TypeScript checks.
Seed local authoring toolchains with exact canonical fetch identities when
they match the selected inputs; retain store-path inputs for overrides.
Add generic correctness checks rather than permanent Reader timing/content
fixtures. Verify actual Reader edits and rejection/recovery in a private
workbench, preserving the original user's workbench and runtime.
Query checking currently caches at resource/closure boundaries, not individual
query semantic dependency boundaries. Template helper pins and reproducible
fixture snapshots follow in a separate publication change.
Project source-free capability contracts and keep exact source provenance in package assembly. Reuse compiled groups across unrelated graph and dependency implementation edits. Keep React public inputs separate from workspace query lowering and retain explicit type-companion dependencies.
Allow independent execution-package checks, scope resource compilation to declared dependencies, and memoize source closure traversal. Document generic-specialization limits and measured Reader rebuild behavior.
Verified protocol, artifact, package, React, and managed activation checks; retained-Git independent/workspace artifact equality and incompatible type dependency rejection; nix fmt -- --check and lint. One-off Reader measurements recompiled 1 of 13 groups for a child edit and 0 for a workspace QX default edit.
