# OPERATING-RHYTHM
Layer 2 Procedural File 5 of 6 — The Dash / NornGate at SBS Owned by: Frigg (cadence). The habituation doctrine in operation — the cadence is the virtue, not any single on-time trigger.
## Purpose
The fleet’s cadence doctrine: what happens daily, weekly, monthly, quarterly, annually — and which dates on the calendar are immovable law. A rhythm missed is reported; a rhythm silently dropped is an incident.
## Daily
• Sif reconciles the prior day’s committed actions against downstream records (orders → invoices → deposits).
• Hel reviews the DLQ: classifications current, no aging corpse unexamined.
• Heimdall issues the anomaly digest; Urd runs the daily chain verify.
• Njord confirms flow health: sent matches received, per pair.
## Weekly
• **The weekly status report** — Frigg assembles, Bragi drafts, human approves and issues (the established SBS weekly-report practice, in the SBS report design system).
• Forseti reviews the override and denial logs (rigorism watch).
• Queue-depth and starvation review; PAWF-class drift check.
## Monthly
• **Month-end close orchestration:** Radio Sales → End-of-Month Accounting close — Thor’s batches, Njord’s flows, Sif’s tie-out, Frigg’s calendar, human certification. The T-minus discipline: every close task has a declared position relative to close day.
• Urd full-chain recompute; break-glass log review (Appendix duty).
## Quarterly
• Break-Glass Roster review and rehearsal (Single-Maintainer-Appendix).
• Idunn’s model evaluation cycle — same gates for every candidate.
• Restore drill (cold-tier retrieval proven, not assumed).
• **Fleet Oversight Package** to the board (per Audit-Trail-Spec).
## Annually
• Annual oversight edition; succession and documentation review for the nine legacy systems; constitutional-file review window (Layer 1 opened only here, absent incident).
## The Statutory Overlay
FCC political-file windows, lowest-unit-charge periods, and filing dates are immovable: they do not negotiate with this rhythm. Frigg’s calendar holds them as fixed points and schedules everything else around them. A statutory date in danger is SEV-1, escalated immediately — never rescheduled silently, never extended by G2. The law does not accept rescheduling requests.
## Authoritative For
Operating-calendar questions; oversight cadence; auditor questions about monitoring frequency.
## What’s Not Here
The close’s financial substance (department procedures); approval classes (10-Governance-Gate-Spec); report content standards (Bragi’s files).
## Modification Protocol
Proposal drafted by the responsible agent → legal/sufficiency review where statutory interpretation is implicated → Odin staffs the synthesis pass → G2 request with full evidence package → human decision per the Single-Maintainer-Appendix authority structure. Approved modifications are versioned (1.0 → 1.1 minor; 1.x → 2.0 material) and captured in Urd’s ledger as policy\_change-class records. Layer 1 files are not modified by this protocol — they require SBS Board / IT Governance authorization via Asgard Policy Review.
