Session 58: Phase 1 — Truth Infrastructure (2327 tests)

ledger_entries is live (migration 019 applied to prod, RLS + NULLS NOT
DISTINCT dedupe verified against the real database). Every grade now
persists, settles against the real result, and carries closing-line value.

- ledgerService: pipeline pre-grade upserts (public model record, user_id
  null, idempotent), closing capture on every snapshot (last write before
  game start = the close), settlement with SIGNED CLV (over = locked -
  closing; beat/faded/flat), 30d model aggregate with the hard n>=20 rule.
- Write paths: snapshotService -> ledger (priority path); Next /api/scan ->
  ledger for authenticated users only (anon never touches the public
  record). Refused reads write nothing and don't burn a scan.
- Honest refusal (work-order 1.5): no projection => insufficient_data,
  grade null, "INSUFFICIENT DATA - no read" UI. The web gradeAdapter no
  longer displays the line as the model projection (the audit's
  model==line / +0% edge degenerate); the card renders absent states.
  projectionFor is sport-aware (l5 -> l20 -> {stat}_per_90 -> xG).
- /ledger: MY READS | MODEL tabs; model header shows hit% + beat-close%
  only at n>=20, else RECORD BUILDING + live pending count. ModelRecord
  deferred-render strip on landing + player hero. CLV + outcome chips,
  revised_from_grade strikethrough (Phase 2.5 ready).
- SYNC (Task 5): thresholds vs SNAPSHOT_EXPECTED_INTERVAL (normal <1.5x,
  amber >=1.5x, STALE red >=3x) via /api/snapshot/summary.
- Phase 2.5 logged in specs/vyndr-roadmap.md (build after Phase 3).
- Data-semantics hardening: strict null-safe numeric parsing everywhere a
  market value is handled (Number(null)===0 would have fabricated lines).

Backend 2309 -> 2327 tests (201 suites), web build exit 0.
