Transitrix Reg-Intel

Collect regulatory-source changes in practice — the operational counterpart to the methodology's codex / SEGMENT / AMENDMENT notation work. Reads the centralised watch-list at operations/config/scan-sources.yaml, runs a cheap change-signal gate before any expensive extraction, then on signal-moved runs the SCAN → SEGMENT → CLASSIFY → OUTPUT pass: fetches and snapshots the source, slices it into obligation-bearing SEGMENT field artefacts, classifies each segment as a CONSTRAINT or REQUIREMENT candidate (positive obligation → REQUIREMENT by default), emits an AMENDMENT field artefact when an existing source has drifted, updates the codex scan block, and stages everything in a review digest for human admission. Never writes canon. Never auto-admits. Never silently drops.
