+## Progress log
+
+### Iteration 1 — Implementation complete
+- P1-0 through P1-7 all implemented via parallel subagents
+- 66 files changed, 1280 insertions, 1229 deletions
+- 25 new tests all passing
+- Type errors from dynamic integration imports fixed with kind-map.ts
+
+### Iteration 2 — Bugbot Review #1
+- Multi-instance integration data cache is process-local → added REDIS_IS_EXTERNAL bypass
+- Board permission changes missing invalidation → added invalidateBoardCache
+- cacheTags.integrationData unused → removed
+- Redis KEYS → SCAN
+- Documented REDIS_CACHE_DB
+
+### Iteration 3 — Bugbot Review #3
+- Inverted tag-expiration check in redis-handler.ts (< → >)
+- Widget interact mutations missing dual-layer invalidation → added requestHandler.invalidateCache()
+- saveItemOptions missing board name → fetch board name
+- importOldmarrConfig missing invalidation → added per-board + list invalidation
+- createBoard homeBoardId auto-set missing user invalidation
+- group.savePositions missing invalidation
+- integration.requestMedia missing invalidation
+- user.delete missing invalidation
+
+### Iteration 4 — Bugbot Review #5
+- Static @homarr/integrations barrel undermines dynamic imports → removed 46 re-exports
+- Duplicate export in common/index.ts → removed
+- SVG XSS test corpus expanded → 10 vectors, <style> tag forbidden
+
+### Iteration 5 — Security Review #5
+- All clear: linkedom+DOMPurify validated, FORBID_TAGS: ['style'] added
+- Cache key design validated (no secrets in keys)
+- Session cookie rotation confirmed
+
+### Iteration 6 — Bugbot Review #7
+- Re-confirmed inverted tag expiration fix
+- saveItemOptions board name fix verified
+
+### Iteration 7 — Security Review #7
+- All clear
+
+### Iteration 8 — Fix commit
+- Committed inverted tag expiration fix + saveItemOptions board name
+- Two-tier invalidation comment added
+
+### Iteration 9 — Bugbot Review #9
+- Tag expiration fix verified correct (aligned with Next.js internals)
+- Full pass over caching comparisons: no other inversions found
+- No bugs
+
+### Iteration 10 — Bugbot Review #10 (Final)
+- **LGTM — ready to merge** at 88% confidence
+- All 10 prior fixes verified
+- No critical or important issues remaining
+
+## Verification
+- 30/30 tests pass
+- trpc.tsx and query-cache.ts unchanged (constraint met)
+- Integration type map resolves subclass methods correctly
+- Redis handler tag expiration comparison verified correct
+- Dual-layer invalidation pattern applied to all widget interact mutations
