THE LEXICON
Every trade develops a shorthand. This is the Bureau's: the labels that number a spec's claims, the bracketed markers that stop a run, and the verdict tokens agents use to pass or refuse each other's work.
The scheme exists for one reason: so that anything downstream can cite an item without re-quoting it. A build prompt says it satisfies FR-7; a run pauses "blocked on OQ-3"; a critic checks AC-11 by number. A label is a type prefix plus a sequence number, numbering restarts per section within each spec, and the reference stays exact no matter how many hands the work passes through.
The deliverable labels
Just as telling is what the Bureau never writes. The standard PM alphabet — NFR, REQ, US, UC, TASK, TC, BUG, RISK — does not appear. The concepts exist; they simply never earn an XX-N code. And a checkpoint is never CP-1 — checkpoints are markers, not labels, which is the next section.
The checkpoint markers
A checkpoint is a bracketed literal in the run narrative. When one appears, the run stops and waits for a human:
[CHECKPOINT] generic stop — a decision belongs to a human [DESIGN-MODEL CHECKPOINT] the design's shape needs a human eye [DESIGN HANDOFF] design leaves the workshop for review [DEV-VERIFIED CHECKPOINT] dev build green — nothing ships without a word [EXTERNAL-ACTION CHECKPOINT] something irreversible wants to fire
Clearing one requires the literal word go. Silence does not count. "Continue" does not count. "Looks good" does not count. The rule is blunt on purpose: a system that proceeds on ambiguity is a system that ships on ambiguity.
The verdict tokens
Each reviewing role has a fixed vocabulary for passing or stopping work — small on purpose, so a verdict can be adjudicated mechanically:
The states of a run
A phase is pending, in_progress, complete, or blocked. The run as a whole derives from its phases: not_started → in_progress → complete → archived, with blocked outranking everything. A run untouched for four hours is stale, and the Ministry of Flow says so out loud. How these live in the state file is Record No. IV — Anatomy of a Run.
The cast that speaks this vocabulary — who rates, who decides, who fetches — is introduced on the main floor, and their model assignments are Record No. II — Cast & Routing.
