TODO.md captures the current state after the first playable browser match, grouped by playability issues, product/infra next steps, engineering debt, and still-open decisions. Each entry records what was already tried and ruled out so the next attempt does not repeat it - notably that trusting MegaMek's font directory did NOT fix the box glyphs, so that theory is dead. README changes: - The "zero patches" constraint was stale; there are now two, so it is reframed as minimal and upstreamable. Both are latent MegaMek bugs, not adaptations. - Documents patch 0002 (heavyweight java.awt.Label breaking PHASE_CHANGE) alongside 0001, with the reason each exists. - Adds a Findings section with the measured numbers the architecture rests on: ~730MB per match flat across heap cap and match size, one game per JVM and why, CPU not being the constraint, the 17.3s units.cache saving, and the 59MB jlink runtime. - Documents the harness/spike layout including the spike package, which was missing entirely. - Notes that harness/run.sh defaults to the stock jar. Also drops a stale comment in run.sh referring to the removed multi-tenancy patch, and untracks spike-webswing/fontconfig.properties - it is generated per-machine with absolute font paths and start.sh recreates it when absent.
