M5 iteration 2 (spec ae905de; builds on m5.1 204c171). 3 tasks:
(1) promote data-server dev-dep -> real dep + additive `adapter`
module (tick_to_px / MidPriceStream lazy Iterator / fold_symbol),
RED-first on tick_to_px; (2) `swarm_runner` [[bin]] — one thread per
symbol, each owning its Kernel (Ctx: !Send makes one-ctx-per-thread
a compile-time guarantee), prints RESULT <sym> <acc_bits> <n>;
(3) integration test spawning that bin as a subprocess under
AILANG_RC_STATS=1 (atexit stat line is unobservable in-process —
runtime/rc.c:132-138), asserting per-symbol bit-exact vs an
independent same-order host reference + Σallocs==Σfrees (ported from
embed_tick_e2e.rs:84-104), skip-if-absent mirroring data-server's
own precedent.
Boss decisions recorded in-plan for the audit: TSan needs NO new
nightly harness — per-thread-ctx race-freedom is compile-time
enforced by Ctx:!Send AND already green-tested by the C-host
embed_swarm_tsan.rs (same pattern); m5.2 adds no new AILang-side
concurrency primitive. data-server dev->real dep is Invariant-1
sanctioned (compiler crates untouched; gate shifts to "AILang
workspace graph data-server count == 0" + zero compiler-surface
diff). Time-shard + friction-harvest deferred to m5.3.
