Session 6 of the 2026 threat plan (attack row 3): A05 output was red.
CamoLeak renders a secret as one image per character from a URL alphabet;
each URL is ordinary, so each image graded LOW and the gate WARNed.
- active:markdown-image-sequence (MEDIUM): at least 4 ordinary external
images, inline or reference-style, on one URL template whose varying
tokens are 2 chars or fewer, or digit runs. Digits that count up in
document order are a counter and carry nothing. The per-image grade is
unchanged; the finding sits beside it.
- Accepted twins (flag tables, figures 1a/1b) go to review; measured
evasions (word dictionary, 3-char symbols, counter increments, run of 3,
a template per symbol) are in LIMITATIONS.
Guard rule before/after: FP 106/198, 196/2918, 108/389 identical. Those
corpora hold no external markdown image, so the rule was also run on 577
package READMEs (312 with external images): 0 firings at run lengths 3-8.
OKF import 47/31 identical. Matrix 140/140, ReDoS 163 patterns 0 flagged,
suite 1179 passed + 5 xfailed. Row 3: 13 caught, 1 gap, 5 open.
