-- Never use `gh` commands that can open an interactive pager and block execution (requiring `q`).
-- Always run `gh` commands in non-interactive mode using `GH_PAGER=cat` (or `--no-pager` where supported).
-- Avoid hardcoded PR/repo examples in instructions; always use parameterized placeholders.

+- Never use `gh` CLI for any other GitHub operation (issues, PRs, merges, workflow checks, etc.).
+- Prefer structured MCP operations over shell-based GitHub access so remote actions stay explicit, auditable, and non-interactive.
+
+## Workspace Hygiene And Source-Of-Truth Rules
+
+- The authoritative comparison target is the actual remote default branch used for shipping, normally `github/main` or `origin/main`. Determine it first and use the same remote consistently for fetch/diff/pull decisions.
+- Before any PR split or branch creation, run a source-of-truth audit:
+   1. fetch the authoritative remote
+   2. inspect `git status`
+   3. compare local `main` against `<remote>/main`
+   4. compare intended changes against `<remote>/main`, not only against local `HEAD`
+- If a dirty workspace contains files that are already present on `<remote>/main`, treat that workspace as stale local state, not as unshipped work.
+- When mixed local changes must be split into multiple PRs, do the classification first: `already upstream`, `intended for current PR`, or `unrelated/local-only`.
+- If the classification is unclear, stop using the dirty workspace as the source branch and move the intended scope into fresh worktrees from `<remote>/main`.
+- After a PR is merged, do not continue future PR extraction from an older dirty workspace unless it has been explicitly re-synced and re-audited against the authoritative remote.
+- **Cleanup is mandatory**: after a temporary worktree, scratch branch, or quarantine workspace is no longer needed, remove it promptly. Do not leave obsolete local worktrees hanging around in Source Control after the task is complete.

+## Testing Strategy Defaults

+- **Default to targeted validation, not shotgun runs**: start with the smallest test command that exercises the changed behavior.
+- **Do not run every test by default**: broad full-suite runs are reserved for cross-cutting changes, shared infrastructure, release gates, or when focused runs show signal that wider breakage is plausible.
+- **Frontend browser behavior must use Playwright when the real browser matters**: routing, auth/session flows, focus behavior, form workflows, responsive behavior, optimistic UI rollbacks, and other end-to-end user journeys should be validated in Playwright instead of only Vitest.
+- **Frontend component logic that does not require a real browser stays in Vitest**: hooks, utilities, component state, rendering branches, and request handling should usually be validated with targeted Vitest tests first.
+- **Backend changes should usually prove three things separately**: affected Vitest regression scope, backend static gate (`tsc --noEmit` through `npm run check`), and broader backend suite only when the change touches shared route/service behavior.
+- **Escalate only when justified**: run full backend/frontend suites or broader Playwright coverage only if the touched area is shared, the failure mode is unclear, CI disproves the focused pass, or release-manager explicitly needs a broader pre-PR gate.
