M5 done 2026-05-19: real backtest over real Pepperstone tick data
through the real external data-server into the shipped M3-frozen
kernel, across a per-thread-ctx thread swarm; symbol-fan (headline
existence proof) + time-shard (first actual proof of chunk-boundary
invisibility); globally leak-free, deterministic. Zero
language/compiler change; one runtime change (7bfa11e atomic
global RC-stats fallback — user-adjudicated bounce-back, RED-first,
+ a build-dep staleness root-caused & fixed). Audit: Invariant 1
PASS, M3 frozen-layout unmoved, gc_rss trio evidenced-RATIFY
(Boehm conservative-scan artefact, Decision-9 transitional), P2
noise causally exonerated baseline-pristine, doc-honesty tidy
clean. Friction-harvest: host-per-tick-FFI ~= ~206 ns/tick at real
EURUSD volume.
- roadmap M5 [~]->[x] with the done-state summary (stays one cycle
for context, then prune).
- roadmap P2 "Flat array/slice primitive" reframed: the
M4-retirement forward note's deferred reconciliation is now
done — the obsolete "1024-cell cons-chain per chunk / M4 ships
it" framing replaced with the real residual (host-per-tick-FFI
vs. batch crossing) anchored on M5's measured ~206 ns/tick; the
M5-dependency is now satisfied (the justification input exists).
- WhatsNew.md done-state entry (verbatim == the notify text):
user-facing, no internals — the embedding arc is complete.
Done-state notification fired (user away per /boss). The next
roadmap item is a new milestone (the P2 flat-array decision or
another P0) — a deliberate user call, not autonomous.
