my nix configs
@pm originally had two read modes — git-ref (via `git show <ref>:TODO.md`) and filesystem. Git-ref existed because the workflow once ran in a bare repo with no working tree. Once the workflow was simplified to assume opencode is launched in the worktree, every dispatch (Phase 2 read, Phase 9 update, Failure handler) uses filesystem mode. Git-ref mode became dead weight: it added bash permissions, an allowlist, a "Bash Discipline" section, and a dual-mode "How to Read" section, but the workflow never invoked it. A reviewer correctly flagged the resulting inconsistency between the two-mode docs and the single-mode usage. @pm is now single-mode. Bash access is removed (bash: false, no permission allowlist). The "How to Read" section collapses to "you operate on TODO/ via the filesystem only" with one explicit pointer that ad-hoc historical reads (`git show main:TODO/GAL-39.md`) are out of scope — the user can run that themselves. The workflow drops the now-redundant "(live filesystem mode)" qualifier from Phase 2 / Phase 9 / Failure handler dispatches and the Roles & Dispatch table updates @pm's constraint to "No bash." |
