The ratchet on tests that read a source file by path matched readFileSync
and readFile only, so a guard that called readSourceText with a fixed path,
directly or through a local read(rel) wrapper, read the file without the
anchors readSource demands and was never counted. The classifier now counts
both shapes, and leaves alone a readSource call with anchors and a sweep that
feeds the reader from a walk.
The twelve guards that read a fixed file that way now go through readSource
with an anchor each read asserts on, so the baseline stays where it was.
walkSourceFiles now lists each indexed folder (src, e2e, prisma) once
per worker and filters it by prefix, readSource and readSourceFolder read
through the same memoised file cache, and readSourceText is the cached
read for guards that read files themselves. The guards project shares a
module graph per worker, so a file is read once however many guards ask
for it. sourcesContaining adds the substring pre-filter for sweeps that
look for a few markers. Every guard over 1.5 s now reads through it;
anything outside the indexed folders is read from disk as before.
The zone-shift and single-Pearson guards now assert that their matchers
find the correct shapes before concluding nothing else matches, and the
dense-read guard lists the streak's per-day existence probe with the
reason it stays bounded.
The /insights envelope (weight x BP, mood x BP, mood x weight, mood x
pulse, BP medication continuity) and the AI feature payload computed
their coefficients with an ungated Pearson that banded |r| above five
pairs, so five days of noise sloping the right way read as a strong
correlation there while every other surface refused the same points.
Both now use `significantPearsonCorrelation` (n >= 20 and p < 0.05,
through the engine's exact p-value), and the ungated function is gone.
The allowlist guard that tracked its remaining callers becomes a guard
that there is one Pearson implementation.
