Implements task 6 of
docs/superpowers/plans/2026-07-07-cyclone-orphan-ack-housekeeping.md.
Adds 'Known historical drift — the 804 orphan 999s' section under
the existing operator-triage content. Covers:
- What the orphans are (real production 999s whose source 837s
predate the current DB snapshot; valid audit history that
cannot be auto-linked)
- Why they cannot be auto-linked (source 837s were transmitted
to HPE and never came back; Cyclone is downstream and does
not retain copies of outbound 837s)
- Triage path via the Inbox AckOrphansLane (already working
as of SP37-followup 893a662)
- Optional synthetic-batch seeding via 'cyclone ack-orphans
reconcile' (one-shot, idempotent, --dry-run available)
- 'cyclone ack-orphans status' for the per-ST02 breakdown
Explicitly calls out what the housekeeping is NOT:
- Not a backfill (no claims rows are synthesized)
- Not auto-runnable (operator-invoked only)
- Not a deletion (orphans are valid audit history)
References the SP38 spec and plan for the design rationale.
RUNBOOK gets a 'Submitting claims (canonical)' section with both CLI
and HTTP examples, the shared cyclone.submission.submit_file helper,
and a 'submit-batch vs resubmit-rejected-claims' decision rule.
CLAUDE.md gets a pointer to cyclone/submission/ in the 'Backend at a
glance' subpackage list.
