+# PRD: BUG-T17 — Rows in Audit Log table automatically fold after user unfolds them
+
+## Objective
+Stabilize the Audit Log table interaction model so row expansion state persists across dashboard refresh/update cycles. Users should be able to open one or more audit rows and continue inspecting detailed payloads without the UI collapsing those rows during periodic data refreshes.
+
+This task is scoped to the frontend rendering/update pipeline for the Audit Log widget in `src/mcpbridge_wrapper/webui/static/`. The backend API contracts (`/api/audit`, websocket update payloads) should remain unchanged unless implementation reveals an identifier stability issue that prevents reliable row-state reconciliation.
+
+## Success Criteria
+- Expanded rows remain expanded after repeated audit refreshes.
+- Collapse state changes only on explicit user click.
+- Behavior remains correct during active tool-call traffic.
+- Existing audit rendering behavior (row ordering, detail formatting) is preserved.
+- Automated tests cover the regression scenario.
+
+## Acceptance Tests
+1. Open dashboard, expand an audit row, wait through multiple refresh cycles, verify row remains expanded.
+2. Expand multiple rows, confirm each remains expanded after updates.
+3. Collapse one expanded row manually, verify only that row collapses.
+4. Run full quality gates (`pytest`, `ruff check src/`, `mypy src/`, `pytest --cov`) with coverage remaining >= 90%.
+
+## Test-First Plan
+- Identify current tests for audit dashboard rendering/update behavior.
+- Add/extend a frontend unit test that reproduces auto-collapse after table update.
+- Assert the fix by verifying expanded state survives multiple update invocations with stable entry identifiers.
+
+## Execution Plan
+### Phase 1: Diagnose Update Path
+- Inputs: current audit table JS update functions, refresh triggers.
+- Outputs: identified state reset point and reconciliation strategy.
+- Verification: local code trace confirms why expansion resets.
+
+### Phase 2: Implement State-Preserving Reconciliation
+- Inputs: expansion state map keyed by stable audit entry ID.
+- Outputs: incremental DOM update or rebuild path that reapplies expansion state.
+- Verification: manual local behavior check under simulated repeated updates.
+
+### Phase 3: Regression Coverage and Validation
+- Inputs: frontend tests and existing web UI test suite.
+- Outputs: regression test(s) proving no auto-fold.
+- Verification: all quality gates pass and validation report documents evidence.
+
+## Constraints and Decisions
+- Preserve existing API schema and data polling cadence.
+- Keep solution lightweight in frontend; avoid introducing new dependencies.
+- Prefer deterministic keying on audit entry ID/timestamp tuple if no dedicated stable ID exists.
+
+## Notes
+- If related row-state reset patterns are discovered in adjacent widgets, capture them as follow-up tasks instead of expanding BUG-T17 scope.

+# Validation Report: BUG-T17
+
+## Task
+Rows in Audit Log table automatically fold after user unfolds them.
+
+## Implementation Summary
+- Added persistent audit row expansion tracking in `dashboard.js` via `auditExpandedRows` keyed by stable row identity.
+- Preserved expanded state across periodic `loadAuditLogs()` refreshes by collecting and reapplying expanded rows after table redraw.
+- Reset expansion state on explicit pagination/filter changes to avoid stale carry-over across different result sets.
+- Added regression coverage in `tests/unit/webui/test_server.py` to assert presence of expansion-state preservation logic in served frontend bundle.
+
+## Quality Gates
+
+### 1) `PYTHONPATH=src pytest`
+- Result: PASS
+- Evidence: `630 passed, 5 skipped`
+
+### 2) `ruff check src/`
+- Result: PASS
+- Evidence: `All checks passed!`
+
+### 3) `PYTHONPATH=src mypy src/`
+- Result: PASS
+- Evidence: `Success: no issues found in 18 source files`
+
+### 4) `PYTHONPATH=src pytest --cov`
+- Result: PASS
+- Evidence:
+  - `630 passed, 5 skipped`
+  - `Required test coverage of 90.0% reached`
+  - `Total coverage: 91.33%`
+
+## Manual Validation Notes
+- Code path confirms previous behavior rebuilt the audit table every 5 seconds and dropped expanded row DOM state.
+- New logic explicitly restores expanded state for rows still present after refresh.
+
+## Verdict
+PASS

+### Critical Issues
+- None.
+
+### Secondary Issues
+- None.
+
+### Architectural Notes
+- The fix keeps state management local to `dashboard.js` and avoids API contract changes.
+- Expansion state is reset on explicit page/filter navigation, reducing stale-row carryover risk.
+- Reopening details after refresh re-fetches payload details for expanded rows; this is acceptable for current scale and keeps implementation simple.

-- [ ] Refactor Audit Log table updates to patch rows by stable entry ID instead of full DOM replacement
