+# Squash + Merge Plan: feature/cvm-relay-stability → master
+
+## Goal
+Squash the 4 commits on `feature/cvm-relay-stability` into a single commit and
+fast-forward merge into master. All tasks are complete and tested (17/17
+integration tests, 61/61 unit tests, 120s stable relay connection on Board B).
+
+## Checklist
+- [x] Write this plan to markdown
+- [x] Rebase `feature/cvm-relay-stability` onto master
+- [x] Squash 4 commits into 1
+- [x] Fast-forward merge into master
+- [x] Run `make test-unit` — 61/61 pass
+- [x] Push master to remote
+- [x] Remove worktree `/home/c03rad0r/esp32-tollgate-cvm-relay`
+- [x] Delete local branch `feature/cvm-relay-stability`
+- [x] Delete stale backup branches (`backup/master-2cd372c`, `backup/pre-squash-cvm-20260519-010933`, `feature/local-relay-backup`)
+
+## Squash commit message
+```
+feat: CVM relay stability fix + MCP relay integration tests
+
+Relay disconnect fix:
+- TLS read timeout reduced from 15s to 1s (short poll loop)
+- Ping timer fires every 30s independently of read activity
+- Consecutive timeout counter (65s) detects real disconnects
+- Handle relay close frames (opcode 0x08) explicitly
+- Result: 120s+ stable connection (previously ~37s disconnect cycle)
+
+MCP relay integration tests (17/17 pass via `make test-cvm-mcp`):
+- MCP initialize roundtrip via relay.primal.net
+- get_sessions returns session array (0 active)
+- get_usage returns metric/price/step fields
+- Non-owner auth rejection (board silently drops)
+- Owner control request passes after rejection test
+
+Build fixes:
+- Remove display/font/axs15231b deps (from display branch, not in this tree)
+- Add esp_timer to CMakeLists REQUIRES
+
+Host unit tests: 61/61 pass
+```
