Fixes bug B-1: page identity is a stable assigned handle (survives edits),
not a content fingerprint; fingerprints identify versions/content for the
equivalence mechanism. Chain: identity -> placements -> equivalence. (§7.2)

The optimal architecture synthesised from INTENT + the full research arc:
- Thesis: canonical at the edges, derived in the middle (orchestrator not engine)
- Dual narrow waist: adapter contract (15 capability spectra) + page model
- 6 layers + provenance/capability rails; L4 union/projection is a rebuildable cache
- Federation-model taxonomy (plural/composable); two-axis projection model;
moldable view registry; identity != placement; computational content in scope
as page-model+projection, out as execution platform
- Concrete src/ module layout with downward-only dependency rule
- Canonical data flows; policy surface; tradeoffs; full traceability to INTENT/UCs
