# Worklog: remove-dagster

Status: complete

## Objective

Remove the retired Dagster package, NixOS service modules, NUC configuration, secret wiring, operational docs, and project-local skill. Stop when no active Dagster references remain, the package output is absent, focused checks pass, and the change is current upstream.

## Decisions

- Remove the complete retired subsystem, not only the package derivation. The disabled NUC modules defaulted to `pkgs.my.dagster`, so deleting only the package would leave broken configuration.
- Remove Bugster and finances Dagster wiring because both are Dagster code locations and already disabled on the NUC.
- Preserve unrelated package-refresh changes and their staged state.

## Evidence

- `nix-instantiate --parse flake.nix hosts/nuc/default.nix hosts/nuc/secrets/secrets.nix` passed.
- `nix eval --raw .#packages.aarch64-darwin --apply 'ps: if builtins.hasAttr "dagster" ps then "present" else "absent"'` returned `absent`.
- Repository grep across `flake.nix`, packages, modules, hosts, docs, and skills found no remaining Dagster or Bugster references.
- `git diff --cached --check` passed; `sem diff --staged` confirmed the removal scope.
- Fresh post-OMP-fix `hey nuc-wt build` exited 0 and produced `/nix/store/rfh7ld31lp7spnsg03iiakk83cyix2q3-nixos-system-nuc-26.11.20260714.18b9261`; the NUC store path exists with the expected system closure.
- `/proc/swaps` on the NUC contains only its header after temporary zram cleanup.
- `hey agent-audit-tests` passed.
- `hey agent-finish --worklog .agents/worklogs/remove-dagster.md` passed the worklog, Darwin configuration, formatting, hooks, tmux, package harness, package policy, ast-grep, agent-quality, test-confidence, and inventory checks.

## Reviews

- Plan review attempted with `hey agent-review plan --active-model-family openai`; blocked by `RUNTIME: Authentication required`.
- Landing review attempted with `hey agent-review landing --active-model-family openai`; blocked by `RUNTIME: Authentication required`.

## Feedback

- Broad scope became clear only after tracing the package's disabled service consumers. Start the worklog as soon as removal crosses package, host, docs, and skills boundaries.

## Remaining work

None.
