Bare-Metal DoE Run Provenance

Master ledger for all 30-replicate DoE runs. Three replications × three architectures = 9 runs total. Each run is itself a complete 2⁴ factorial experiment (16 configs × 30 reps = 480 runs), making this a nested/hierarchical DoE: 9 outer cells × 480 inner runs.


Outer DoE Design — Run Order Matrix

Balanced so each architecture appears in each position exactly once:

Position Rep 1 (seed 12345) Rep 2 (seed 67890) Rep 3 (seed 13579)
1st run amd64 riscv64 aarch64
2nd run aarch64 aarch64 amd64
3rd run riscv64 amd64 riscv64

riscv64 occupies all three positions across reps (3rd, 1st, 2nd) — best achievable balance given the first two orderings.

Inner DoE factors (2⁴ = 16 configurations, shuffled by seed via Fisher-Yates):

Factor Low High
Entropy thresh 0.50 0.75
CV threshold 0.10 0.15
Temporal decay 0.30 0.50
Stability flag 0 1

Config presentation order is shuffled per-run using the DoE seed (doe.4th Block 2054). Same seed → same shuffle (reproducible). Different seeds → independent permutations.

Note on inner DoE CSV extraction: EMIT-ROW output (480-row per-run summaries) is fragmented by the 10µs heartbeat interrupt firing mid-print. These rows are not reliably extractable from existing logs. Fix planned: atomic row buffer in doe.4th before next campaign. Current analysis uses heartbeat stream only.

MD5: aarch64 ≠ riscv64 in heat columns from tick 34,001; all attractor metrics (exec_delta, window_width, time_trust, variance) identical across all three.

Latin Square Seed D — Seed 54321 (2026-06-14)

Run order: amd64 → riscv64 → aarch64

Context: This is the first run using the corrected QEMU termination condition (-lt 3 instead of -lt 2). Prior to this fix, the REPL command echo ([Hera] zuse)ok> 54321 30 EXEC-DOE) bumped the grep count to 2, killing QEMU before EXEC-DOE ran. All three arches now produce full 261k-tick runs.

All three arches agree at 261,096261,099 ticks (within 3 ticks of boot-phase variation). APIC timer active on amd64 (apic_ticks advancing); riscv64 and aarch64 show apic_ticks=0 (APIC not wired for those ISAs in current kernel).


Superseded Runs (kept for audit trail, NOT used in analysis)

Arch CSV filename Rows Date Reason superseded
amd64 doe-amd64-20260611-012412.csv 261,097 2026-06-11 Transitional build — EXEC-DOE was trivial alias

riscv64 doe-riscv64-20260611-191335.csv 261,095 2026-06-11 Superseded by Rep 1 clean re-run

The original aarch64 and riscv64 (2026-06-11) were byte-for-byte identical. This was a single-session observation; Rep 1 re-runs show heat variation between arches while attractor metrics remain invariant. See report §7.5.

Files dated 2026-06-09 and 2026-06-10 are development iterations with varying rep counts, incomplete capsule implementations, or aborted builds. Retained for git history, excluded from all analysis.


New 3×3 Campaign — ACL-Corrected Build (2026-06-15)

Identical design to the original 3×3 (same seeds, same run orders, 30 reps), re-run after two correctness fixes:

  1. ACL.4th and zuse.4th moved to correct block range (4000+)
  2. QEMU termination condition fixed (-lt 2-lt 3) so EXEC-DOE runs to completion
