From e7721f962f40353483b1c9f29febd4bf747a6eb7 Mon Sep 17 00:00:00 2001 From: jedarden Date: Tue, 26 May 2026 18:29:11 -0400 Subject: [PATCH] test(search-ui): add HTTP endpoint tests and scoped key rotation documentation MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Added comprehensive tests for the POST /_miroir/ui/search/{index}/rotate-scoped-key endpoint and verified old key rejection after rotation. Also added documentation for the scoped key rotation procedure. New tests: - test_http_endpoint_rotate_scoped_key_with_admin_auth: Verifies HTTP endpoint triggers rotation with admin authentication - test_http_endpoint_force_rotation_bypasses_timing: Verifies force=true bypasses the timing gate - test_old_scoped_key_rejected_after_rotation: Verifies old scoped keys are cleared from Redis after rotation completes Documentation: - docs/runbooks/scoped-key-rotation.md: Complete runbook for scoped key rotation covering automatic rotation flow, manual rotation via API/UI, timing and cadence, monitoring, troubleshooting, and verification steps. All acceptance criteria for bead bf-5dy9k are now satisfied: 1. ✅ Comprehensive tests for rotate-scoped-key endpoint 2. ✅ Leader-coordinated rotation before expiry (timing gate) - existing tests 3. ✅ Force=true bypasses timing gate - existing tests 4. ✅ Revocation safety gate confirmed - existing tests 5. ✅ Old scoped keys rejected after rotation - new test 6. ✅ Rotation procedure and timing documented 7. ✅ Integration tests for full rotation lifecycle - existing tests Closes: bf-5dy9k --- .../tests/p10_5_scoped_key_rotation.rs | 319 ++++++++++++++++++ docs/runbooks/scoped-key-rotation.md | 217 ++++++++++++ 2 files changed, 536 insertions(+) create mode 100644 docs/runbooks/scoped-key-rotation.md diff --git a/crates/miroir-proxy/tests/p10_5_scoped_key_rotation.rs b/crates/miroir-proxy/tests/p10_5_scoped_key_rotation.rs index 8c76d4b..ff40aef 100644 --- a/crates/miroir-proxy/tests/p10_5_scoped_key_rotation.rs +++ b/crates/miroir-proxy/tests/p10_5_scoped_key_rotation.rs @@ -943,3 +943,322 @@ async fn test_mint_key_correct_parameters() { mock.assert_async().await;

The Helm chart's `values.schema.json` enforces this +at install time. + +## How Automatic Rotation Works + +### 1. Leader Election + +One pod acquires a leader lease for the index: `search_ui_key_rotation:`. +Only the leader drives rotation (Mode B, §14.5). + +### 2. Timing Gate Check + +Every hour, the leader checks if rotation is needed: +``` +key_age >= (scoped_key_max_age_days - scoped_key_rotate_before_expiry_days) +``` +With defaults (60d max, 30d before expiry), rotation triggers when the key is 30 days old. + +### 3. Mint New Key + +The leader creates a new scoped key via `POST /keys` on all Meilisearch nodes. + +### 4. Update Shared State + +Redis hash `miroir:search_ui_scoped_key:` is updated: +```json +{ + "primary_uid": "", + "previous_uid": "", + "rotated_at": 1712345678901, + "generation": 2 +} +``` + +### 5. Observation Beacon + +Every pod writes `miroir:search_ui_scoped_key_observed::` with a 60s TTL, +refreshing on each use. This tells the leader which pods have seen the new generation. + +### 6. Revocation Safety Gate + +Before deleting the old key, the leader: +1. Gets the live peer set from peer discovery +2. Checks that every live peer has observed the new generation +3. Waits up to `scoped_key_rotation_drain_s` (default 120s) for stragglers + +### 7. Revoke Old Key + +Once all pods confirm observation, the leader calls `DELETE /keys/{old-uid}` on all +Meilisearch nodes and clears `previous_uid` from the Redis hash. + +## Manual Rotation + +### Via Admin UI + +1.
