This rehearsal validates the five-stage Meridian mechanism without exposing the December book-cipher corpus, canonical Angle Script question, inbound email keyword, HORSESHOE code, or Firmament document.
A scheduled LIVE broadcast will eventually carry faction-separated book-cipher coordinates. Training uses a local simulation and the intentionally impossible notation 13:70:39 as an in-world station marker, not a duration format.
LIVE will be keyed to an immutable hash of the final published Book One. Training uses this fixed one-paragraph corpus. Coordinates are chapter.word; take the first letter of each referenced word, then interleave the Resistance and Vril halves by coordinate number.
The proposed one-off Firmament rune alphabet has been retired. The mission now uses Sid Kidd's canonical Angle Script, the six-Hour alphabet designed for recurring use across the series.
This describes spoke positions and marks without supplying the Roman letters.
The canonical question, its answer, the Diminuto inbound-email trigger, final theory payload, reward code, Meridian badge transaction, and LOOSH award are deliberately absent from TRAINING. LIVE will substitute those payloads only after the published-edition book cipher is frozen and the cross-faction path is verified.
Reward freeze: no LOOSH, HORSESHOE code, Firmament document, Signal Clearance badge, or canonical mission completion is issued.
