 ## Workflow
 
-- Use `todo.txt` as the source of truth for staged work.
-- Preserve the todo status markers:
-  - `-` means open.
-  - `+` means implemented, needs testing.
-  - `X` means tested and done.
-- Work in small batches and update `todo.txt` only for items actually completed
-  or tested.
-- Before beginning a new phase or section, review all earlier `+` and `X`
-  sections in `todo.txt`; confirm their status still matches the code, tests,
-  docs, and user-facing surfaces, and downgrade stale `X` markers when evidence
-  no longer supports them.
+- Skald is production software; prefer small, scoped maintenance changes with
+  focused verification.
+- Use a temporary local plan file only for large or risky batches that need a
+  resumable checklist.
+- Building the Arch package updates `distro-packages/Arch-Linux/skald-git/PKGBUILD`
+  with the generated `pkgver`, so this file is often dirty after package builds.
 - Keep changes scoped to the current batch.  Do not mix in unrelated cleanup.
 - Before behavior changes, inspect the current code path and tests rather than
   assuming Galene behavior still applies.
