The header scan (Captain Bob, 2026-11-10): 788 source files -- 351 with the
SL-1.0 header, 12 with the old name (docs/working/experiments, kept by
ruling), 31 under someone else's licence (tools/kconfig, Linux's, GPL-2.0:
kept), and 394 with none. Ruled: the SPDX form; capsules (.4th, .f18) and
proofs (.thy) left for a ruling of their own (mkcapsule's 64x16 block format,
content-addressed capsules).

as a /* */ block (C, headers, assembly, linker scripts) or # lines (scripts,
Makefiles, Kconfig; below a shebang or a coding line); tools/mkcapsule.c,
which had the copyright line, gets the SPDX line only.
Not touched: docs/working/ (archive and old campaign material, as the
ruling kept the experiments); v4/system/post_cases.c (generated by
v4/tools/mkpost.py, "do not edit" -- the generator has the header).
Comments only: the kernel builds on amd64, aarch64, riscv64; make -C v4
test-32: 39 programs, 0 failures; every changed script parses.

These are data in their own right (the per-trial-labeled telemetry, one
step before merging into combined.csv), not disposable scratch -- keep
them alongside it rather than only documenting how to regenerate them.

Correlates every HB-ON/HB-OFF heartbeat-tick CSV row (results-20260912-
with-heartbeat-csv/*-doe-raw.log) back to which trial (run_id, id_idx,
id_label, rep) was active when it printed, despite the async tick
printer splicing rows mid-token -- including mid a DOE-RUN marker itself
-- into the trial loop's own console output on the shared serial line.
Pipeline (analysis-20260912/, see its own README.md):
- correlate_doe.py: two-pass reconstruction per architecture (remove
atomic CSV-row spans to rebuild the clean trial-output stream, map
each removed row's offset back to the nearest preceding run_id
marker); identity/rep looked up from a known-clean prior run's
run_id mapping rather than re-parsed, since one aarch64 marker
(trial 12, rajames rep 1) lost its id_idx digit to a zero-separator
collision with an adjacent CSV field and is unrecoverable from that
log alone -- its rows fold into trial 11 instead, documented as a
known limitation.
- combine.py: merges all three architectures into combined.csv (768
rows), decoding Q48.16 fields to floats and jitter_bits' IEEE754 bit
pattern to real jitter_ns.
- analysis.R: per-cell (architecture x identity) means/SD and two-way
ANOVA for each of 12 telemetry metrics, one boxplot SVG per metric,
written up as ANALYSIS.md.
Key findings: identity significantly affects word-heat/window-sizing
metrics (expected -- different identities execute different word
sets), architecture significantly affects timing metrics (APIC
ticks/tick, timing variance, fleet heat -- expected, different QEMU
targets), zero architecture x identity interaction on any metric.
