…NG-608) Moves the producer onto the published typed contract: - internal/ledgeringest gains the typed v1 wire model and the mapper from exported store rows — the single legacy->v1 name authority on the CLI (renames, drops, closed-vocabulary guards, decided-row mirrors derived from the decision fact so they can never disagree). - Receipts are now created in the clean payload/proof shape: sections omit empty members, tool_call_id is the sole correlation field, the stored payload is the RFC 8785 (JCS) bytes the hash commits to, and unsigned receipts omit the signature on the wire. A payload_form column marks clean rows; local chain verification is unchanged. - Session lifecycle rows stay local: they no longer mint receipts and never reach the wire — session records carry open/close state. - Contract-form selection is deterministic per export page, never error-driven: any pre-cutover receipt or fact-less decided action pins its page to the legacy form, which is how pre-upgrade backlog (including rows written during a temporary downgrade) drains; pages of post-cutover rows ship v1, as do heartbeats. A 409 replay conflict on the v1 form is isolated like an oversized page instead of retrying the same bytes forever. - The transport test validates real flush bytes — decoded untyped, so a typed struct cannot hide a dropped field — against the pinned contract schema, proves session rows never leak, checks heartbeats, and covers the pre-cutover legacy drain.

What
Stacked on #447. Moves the daemon's producer onto the published ledger-ingest v1 contract — typed records, clean field names, JCS-hashed receipts — with a deterministic drain path for pre-upgrade backlog and no error-driven form fallback.
How
internal/ledgeringest): the single legacy→v1 name authority. Renames (canonical_event_type→event_type,decision_at→decided_at,*_jsonnames dropped,tool_use_id+tool_call_idcollapsed), removals (fields no producer populates), closed-vocabulary guards, and decided-row mirrors derived from the decision fact itself so the server's cross-checks can never disagree.payload_formcolumn (additive migration) marks clean rows. LocalVerifyReceiptschain verification is unchanged for old and new receipts alike.session.start/endrows no longer mint receipts and never reach the wire; session records carry open/close state, as the contract specifies.409replay conflict is isolated like an oversized page (shrink → skip) instead of retrying identical bytes forever.Tests
payload_form='legacy'ship on the legacy form with no hybrid markers.go test ./...green.Rollout
Ships only after the server accepts the v1 form in production (staging channel first). The legacy serializer stays for exactly one release to drain pre-upgrade rows; its removal is the follow-up PR.
