Failure #35 is the largest defect found so far and it was invisible from the
code: 9 runs lost to one Act 1 boss, all with the same cause, all recorded in
the run files as damage taken, turns elapsed and potions spent. Recorded with
the reproduction, the fix, and the replay that verifies it.
Also adds a rule to the docs index: re-measure numbers before copying them.
Test counts, latencies and run totals in these notes have gone stale more than
once -- a hand-off summary recorded 29 and 118 assertions where the suites
actually printed 50 and 131.
DESIGN.md covers the three-layer architecture (facts in code, Jev for
tactics, gated escalation for macro). research/ documents the engine and
mod surface, the Jev classifier's measured behavior, the STS2MCP HTTP
interface, state shapes, failure modes, decision architecture, and a
run log of the first four sessions.
