Remove nix hash refresh tasks by schickling-assistant · Pull Request #646 · overengineeringstudio/effect-utils

schickling-assistant · 2026-05-08T13:05:09Z

Problem

The shared devenv Nix task module still exposed generated nix:hash refresh tasks. Those tasks were a legacy interface and encouraged ad hoc hash refresh workflows from inside this public helper package.

Goal

Keep the shared Nix task surface focused on public, tool-neutral validation/build commands and let downstream repositories own their own fixed-output hash refresh orchestration.

Decisions

Removed the generated nix:hash task family from nix-cli.
Kept the public validation/build tasks: nix:check, nix:check:quick, nix:build, and nix:flake:check.
Left hash refresh behavior out of this package instead of baking a downstream-specific workflow into the public module.
Updated tests to assert the old hash-refresh task surface is not generated.

Verification

nix-instantiate --parse nix/devenv-modules/tasks/shared/nix-cli.nix
bash nix/devenv-modules/tasks/shared/tests/nix-cli-no-hash-refresh.test.sh
env -u OTEL_STATE_DIR -u OTEL_EXPORTER_OTLP_ENDPOINT CI=1 devenv tasks run nix:test --mode before --no-tui --show-output
env -u OTEL_STATE_DIR -u OTEL_EXPORTER_OTLP_ENDPOINT CI=1 devenv tasks run check:quick --mode before --no-tui --show-output

Complexity

No new complexity; this removes generated task surface area.

Concerns

Downstream repositories that still call nix:hash:* need to move to their repo-owned hash refresh workflow before consuming this change.

Follow-ups

None in this repository.

Supersedes #645.

Problem Report

Diagnosis: Head SHA was current. The deploy-storybooks failure came from a mechanical Jsonnet regression in nix/devenv-modules/otel/dashboards/dt-duration-trends.jsonnet: the nix:hash panel call was removed but its surrounding at(...) wrapper remained with only coordinates, breaking the Grafana dashboard derivation needed by the devenv shell. Removed the dangling wrapper, committed 71b6dce15b4a0e8a9bb6ec7768442e68dcd5c50c, and pushed it to schickling/2026-05-08-remove-nix-hash-refresh.

Verified options:

Affected dashboard Nix proof
- Plan: Build the failing dashboard surface through nix/devenv-modules/otel/build-dashboards.nix with only dt-duration-trends.
- Verification: Passed; produced /nix/store/vsbrjyy1rxw0p5105i8mzfmp1f4hjb30-otel-dashboards-extra.
- Tradeoffs: Narrow proof directly covers the failed grafana-dashboards.yaml dependency surface.
Repo quick gate
- Plan: Run devenv shell -- dt check:quick --no-tui in PTY co1-cobalt-0286-check-quick.
- Verification: Passed: 18 succeeded, 7 skipped.
- Tradeoffs: Quick gate covers TS and lint; full tests were not run because the fix is a scoped Jsonnet syntax repair under merge-queue escalation deadline.
Publish verification
- Plan: Push detached worktree HEAD explicitly to the PR branch and verify remote head.
- Verification: Remote refs/heads/schickling/2026-05-08-remove-nix-hash-refresh is 71b6dce15b4a0e8a9bb6ec7768442e68dcd5c50c; worktree is clean.
- Tradeoffs: Canonical megarepo worktree is detached, so push used HEAD:refs/heads/....
