      "Title": "Measured: the 1000-probe scan costs 26.8% of a core idle; reaper.file_exists is 1.26x cheaper",
      "Excerpt": "`process_request` already carries a TODO about the fixed 1000-probe scan, and the reasoning there is right, including why `reaper.EnumerateFiles` was reverted in 1.6.1. This is not a new bug report — it is the measurement that comment is missing, plus one lever that does not require touching the protocol.\n\n### Measured in REAPER's own Lua\n\nAgainst the real, empty mailbox, min-of-12 runs, REAPER 7.78/x64, Windows 11:\n\n| | ms per tick |\n|---|---|\n| `io.open` × 1000 (what the bridge does today) |…",

      "Title": "File transport falls back to unslotted writes whenever the version probe has no verdict, and the response carries no request id to catch the collision",
      "Excerpt": "Two things that are individually defensible combine into cross-talk: the fallback path in `reaper_call_file` writes without claiming a slot, and the response wait has nothing to check the answer against.\n\n### The fallback is entered on \"no verdict\", not just on \"old bridge\"\n\n`reaper_call_file` uses the pre-1.6.6 single-shot write whenever `_bridge_check[\"claims_ok\"]` is false (`reaper_mcp_server.py:311`). That flag is only ever set true inside the one branch of `ensure_bridge_current()` where…",

Server restart loop\n\nIt seems like line 16 in `reaper_mcp_server.py` sets `__name__ = \"twelvetake-reaper-mcp\"`, which I think overwrites Python's built-in `__name__` variable. That means `if __name__ == \"__main__\":` on line 2180 never evaluates to true, so `main()` never gets called. The server exits immediately and the MCP…",

The decoder then does:\n\n```lua\ns = s:gsub('\\\\(.)', function(c) return escapes[c] or c end)\n```\n\n`\\u` is not in the escape table, so the backslash is dropped and the letter `u` is kept. The codepoint digits stay. Result: the string for 可 arrives in REAPER as the literal ASCII `u53ef`.\n\nOn Windows this wrote broken…",
