Final functional M5 iteration (specae905de, plan 67027ab; on green m5.1204c171+ m5.2b724cd1whose leak-proof resolved viadbd76e5). Proves the chunk/window-boundary-invisibility claim the M4 retirement rests on: - adapter::fold_window — purely additive windowed sibling of fold_symbol (same MidPriceStream+Kernel path; stream_tick_windowed). fold_symbol/MidPriceStream/Kernel byte-untouched. - chrono as a DEV-dep only — the time-shard test derives (y,m)->Unix-ms bounds (data-server's own precedent) and passes raw ms to the bin; the bin is date-math-free; Invariant 1 unaffected. - new single-responsibility [[bin]] timeshard_runner — one thread per disjoint window, each owning its Kernel (Ctx:!Send => compile-time per-thread-ctx). - tests/timeshard.rs — spec §3 strength-ordered: (a) per-shard (acc,n) BIT-EXACT vs single-thread host fold of that exact window in stream order (THE boundary-invisibility proof); (b) Σ partials bit-exact by construction; (c) whole-window within REL_TOL=1e-6 only (cross-shard f64 reassociation is host arithmetic, never a kernel property — bit-exact there would be the bug; tolerance derived from the recursive-summation error bound). Plus the now-deterministic leak-Σ + a journal-only friction timing capture (no bench gate, no timing assertion). Concrete pin: EURUSD 2017-03/04/05 (recon-verified present, contiguous, no gaps; data-server has no month-listing API). RED was a genuine deterministic compile failure (declared-but-absent bin source; Cargo missing-source error vs the plan's predicted env! error — same cause, no false-green; benign plan-text imprecision in Concerns). Boss-verified independently: timeshard determinism 5/5 (no jitter); full ail-embed suite 0 failed AND 0 ignored across all binaries (m5.2 symbol_fan_swarm_leak_free stays un-ignored & green — the saga's resolution intact); isolated embed_rc_global_stats_race still green; AILang workspace data-server count 0; compiler-surface diff empty (zero diff to crates/ailang-*, crates/ail/, runtime/, examples/*.ail, root Cargo.toml, DESIGN.md). Friction-harvest deliverable (P2 flat-array-decision input): host-per-tick-FFI ~= 658 ms / 3,192,562 ticks ~= ~206 ns/tick at real EURUSD volume. M5 functional work complete; milestone closes next via the mandatory audit (which also handles the pre-existing DESIGN.md:2358-2360 "additive M4 concern" drift, out of m5.3 scope). Includes the per-iter journal, stats, and the INDEX.md line.
