Current Work (newest first)

• [2026-02-23T04:47:40Z] completed: patched cold-start gate in plugin/subminer.lua, added Lua regression harness, validated red->green + syntax + focused launcher mpv tests.
• [2026-02-23T04:49:00Z] intent: reproduce root cause from user logs; add red test first; patch plugin start gate with minimal behavior change.

Assumptions

• Regression introduced by is_subminer_ipc_ready() check at start of start_overlay().
• Cold-start should not require pre-existing process; socket checks remain valid once process exists.

Open Questions / Blockers

• None.

Next Step

• User runtime verification: launch with SUBMINER_APPIMAGE_PATH=... ./dist/launcher/subminer --log-level debug ... and trigger y-s.
