+# 🟢 SESSION 79 — READ-CARD NO-MARKET EMPTY STATE + PRICED-LINE SURFACER (2026-07-22)
+The S78 diagnosis (join works, marketless scans rightly self-hide) → made the
+absence LEGIBLE without fabricating a market.
+
+## Phase 0 gate (all clear)
+- **Design-check:** built to the triplet's own REFUSAL honesty language + the
+  existing `EmptyState` path-forward pattern — NOT freelanced.
+- **Reachability:** scanner already fetches games/odds/search; snapshot is ONE
+  more public 30s-cached fetch per sport.
+- **Staleness = inherent guard:** every scan re-validates the market
+  server-side at submit, so a surfaced line that rotates → honest empty state on
+  tap, never a vanishing triplet.
+
+## What shipped
+- **`web/src/lib/pricedLines.js`** (pure, tested) — `indexPricedLines` keeps
+  ONLY snapshot rows with a real `book_odds`, keyed by exact `nameKey|stat`.
+  Wrong stat → []; off-slate → []; nothing suggested/interpolated/nearest.
+- **`web/src/components/vyndr/NoMarketState.tsx`** — honest empty state: no
+  market numbers of its own; real priced lines as one-tap chips OR a link to the
+  board. Path forward, not a wall.
+- **`scan/page.tsx`** — snapshot fetch + "PRICED TONIGHT" help chips under the
+  free-typed line input (help, not restriction — any prop still scannable) +
+  the empty state when `book_odds==null || fair_odds==null`. Tapping a chip
+  pre-fills + re-scans (market re-resolved server-side).
+
+## 🔴 REVERSIBILITY (the design constraint) — VERIFIED
+`GradeResultCard.tsx`, `PriceTriplet.tsx`, `gradeAdapter.js`, `valueState.js`,
+`routes/scan.js` and the Next `api/scan/route.ts` are **BYTE-IDENTICAL** (a test
+asserts none reference the new UI). All new behavior is in 2 added files + one
+additive scan-page block. **Scan A untouched; free-tier model-lock intact.**
+
+## Proven live
+- Surfacer on live snapshot: `Sam Huff hits` → exact match returns
+  `[o0.5? no — u0.5 @105]`; wrong stat → `[]`; Aaron Judge (off-slate) → `[]`.
+- Scan A (Sam Huff hits 0.5 under): `book 105 · fair 120` → triplet renders,
+  empty state hidden.
+- Scan B (Sam Huff hits **3.5** over): grade D, no market → **empty state shows**
+  + surfacer offers the real o0.5 line.
+
+## Still open (unchanged; NOT this order)
+- No settled `p_win` yet → adjuster measurement not begun.
+- env_multiplier on a ledger row pending next MLB lock.
+- mappingHarness nomination flow · A/D emission · EV overconfidence ·
+  edge_pct surfaces · 3 key rotations (PAT stripped locally S-runbook; Kev must
+  still REVOKE on GitHub + rotate internal key + Storage Box password).
