Modules

b64

hP / hQ — standard base64 encode over the alphabet hI captured at line 583 of the eT15wiaE init.js:

offsets

vN(target, lenBound, secret) — offsets PRNG. See r3-sensor-grammar-2026-05-20.md for the un-flattened VM trace.

remap

vM(t, n, e, r, g) — linear remap from [n, e] to [r, g], Math.floor-rounded. JS reference:

secret

vL() — secret-feed builder. JS reference:

sensor

vP — top-level sensor encryptor. Chains the six primitives in the captured init.js (line 6050) into the single output the runtime POSTs to /<tenant>/xhr/b/s:

splice

vQ(salt, payload, offsets) — interleave salt characters into the base64 payload at byte positions produced by vN. Final step of the eT15wiaE sensor encryption stack.

xor

jw(t, n) — single-byte XOR stream cipher used by the eT15wiaE tenant for both the payload stream (key IS = 50) and the secret feed (key VJ = 10). See px-research/notes/eT15wiaE/r3-….
