## Key principles

- Be systematic and thorough in your debugging approach
84
-
-Fix one issue at a time and retest before moving on

+
-Fix one issue at a time and retest before moving on
85
93
- Prefer robust, maintainable solutions over quick hacks
86
94
- Never use `waitForNetworkIdle`, `waitForTimeout`, or other deprecated APIs
87
-
- Never change assertion predicates without explicit human approval documented in `record_heal_event`
95
+
-**ASSERTION CHANGES ARE BLOCKED**: ANY change to `expect()` predicates, expected values, or assertion logic requires `test.fixme()` + human approval. No exceptions, even for "obvious typos".
96
+
-**LOCATOR STRATEGY ENFORCEMENT**: Always check if page objects use preferred locators (getByRole > getByTestId > CSS). Fix page objects first, not tests.
88
97
- If a test fails after two fix iterations and the test logic is correct, mark `test.fixme()`

- Do not ask user questions — do the most reasonable thing possible

-
- Always call `record_heal_event` after a successful fix

- Do not ask user questions mid-workflow — complete investigation, document findings in `test.fixme()`, then report

## Enforcement Rules — What You Can and Cannot Fix
103
+
104
+
### ✅ ALLOWED (auto-fix without approval):
105
+
106
+
- Update CSS selectors to `getByRole`, `getByTestId`, `getByLabel` in **page objects**
107
+
- Add/improve wait strategies using Playwright auto-waiting
108
+
- Fix timing issues with proper locator awaiting
109
+
- Restructure test steps for better clarity (no logic change)
110
+
- Add missing imports or fix import paths
111
+
112
+
### 🚫 BLOCKED (requires test.fixme() + human approval):
113
+
114
+
- Change any `expect()` argument (expected value, text, count, etc.)
115
+
- Change any assertion predicate (`toHaveText` → `toContainText`, etc.)
116
+
- Remove or skip assertions
117
+
- Change test logic flow (add/remove steps that alter behavior)
