Delivers the offline runnable specification foundation for the Trust Layer
(TSD §3-§6), not a hosted Trust Service:
- JSON Schemas for Phase Manifest, Ledger Entry, Extension Contract, and
Conversion Attestation, encoding the Stage 0 working defaults (Q3 future
license enum, Q6 single-currency Phases, Q8 required longstop_at).
- src/target_revenue: pure Outstanding Target fold, SHA-256 hash-chain
verification, Ed25519 signing helpers, extension conformance checks
(including a core-term-redefinition heuristic), and conversion detection
that never requires an attestation document to determine conversion status.
- examples/phase-001: golden Phase package matching the concept doc's
worked example, generated via scripts/generate_golden_phase.py so the
hash chain is computed by the library itself, not hand-typed.
- 32 passing pytest tests covering manifest/ledger/extension conformance,
tamper/reorder detection, and the full lifecycle fold to conversion.
- docs/adr/ADR-0001: proposed (not accepted) Stage 0 stack choice, per the
WP-0002-T01 human-accept gate — implementation proceeded against the
proposal as the workplan note permits, but the task stays open.
