DISPATCH D-0113 · DECLASSIFIED

SOLVED BY NIGHTJAR  ·  00:03:47  ·  2026-04-19 04:03 UTC

I. Intercept Transcript

At 00:00:00 UTC the following ciphertext was broadcast via the Cipher oracle channel under dispatch identifier CX-438. The payload was encoded under Base64 and delivered as the UTF-8 literal Tk8gU0lHTkFMIEZST00gU1RBVElPTiBaVUxV. The oracle signed the payload with its standing key and anchored the reference hash to the vault contract at block 104,229,118.

II. Decryption Notes

Operative NIGHTJAR submitted the correct plaintext at T+00:03:47, a Base64 decode of trivial difficulty. The plaintext reads: NO SIGNAL FROM STATION ZULU. A total of 18 wrong attempts were logged during the solve window, yielding a post-burn of 14 $CIPHER under the anti-spam rule.

III. Pot Distribution

Pot of 39,800 $CIPHER transferred to NIGHTJAR's primary vault. Consolation pool of 4,685 $CIPHER split between GREYFOX (2,108), STATIC (1,405) and KITEFRAME (1,172), rank-ordered by solve time. Treasury retained 2,340 $CIPHER.

IV. Retrospective

A base64 dispatch at EASY tier is considered entry-level. Solve times below four minutes are common. NIGHTJAR's streak now stands at four consecutive first-solves, tying the project record. Next dispatch tier promoted to MODERATE.
