+# D1 CLOSE — REVIEW ZERO FINDINGS (report; mount NOT performed)
+2026-07-31. Nothing changed: no mount, no row edit, no data threading.
+`git diff` = docs only.
+
+## Why this stopped at Review Zero
+
+The order scopes this as "mount only — NO row refactor." Reading the real components shows the
+mount is **not** a mount, and one finding needs a decision before anything is surfaced.
+
+### 0.1/0.2 — THE RATIONALE DOES NOT REACH THE ROW (VERIFIED)
+`StripProp` (`components/vyndr/StatStrip.tsx`) carries stat · line · side · grade · gradedAt ·
+delta · awaiting · outcome · movement · revisedFrom · book · bestBook · dead · history —
+**no `reasoning`, no `kill_conditions_triggered`.** `buildPlayerStripsFromProps` never threads
+them either. So mounting the hover requires **adding a field to the strip contract and threading
+it through the slate adapter** — additive, but a data-path change, not a mount.
+
+### 0.3 — THE PREMISE INVERTS: THE RATIONALE IS **ALREADY PUBLIC** (VERIFIED LIVE)
+The order asks me to ensure "a free-tier user's hover shows nothing, not the paid reasoning."
+Measured against prod, anonymously:
+
+    GET https://api.vyndr.app/api/snapshot/wnba   (no auth)
+      reasoning.summary present : True
+      reasoning.locked          : None
+      kill_conditions_triggered : 1
+
+**`stripModelPrice` strips `model_odds`/`p_win`/`ev_pct`/`value`/`takeable` — it does NOT strip
+`reasoning` or `kill_conditions_triggered`.** So the full model rationale is already shipped to
+every anonymous browser on the main board endpoint.
+
+**Two consequences, and they pull in opposite directions:**
+1. Mounting the hover **leaks nothing new** — it renders bytes the browser already has.
+2. But it **surfaces** something currently shipped-but-unrendered, and the same content **IS**
+   tier-gated on the scan path (`utils/tierGating.js` redacts `reasoning` for free tier). So the
+   product currently gates the reasoning in one place and serves it openly in another.
+
+**This is a monetization/consistency decision, not an implementation detail** — which is why it
+is reported rather than resolved unilaterally. Three coherent options:
+- **(a)** Gate `reasoning` on `/api/snapshot` the way scan does, then mount the hover for entitled
+  viewers only. Consistent, but removes content free users already receive.
+- **(b)** Accept it as intentionally free (board reasoning is the funnel) and mount for everyone.
+  Consistent the other way; makes the scan-path gating the odd one out.
+- **(c)** Leave the payload alone and don't surface it. Status quo.
+
+### THE THIRD BLOCKER — ROW-GRAMMAR IS LAW AND LOCKS StatStrip's SOURCE ORDER (VERIFIED)
+`tests/unit/rowGrammar.test.js` asserts StatStrip's element order by **`src.indexOf(...)` on the
+component source** (slots: identity → viability → stat+line → market context → model output →
+outcome → actions → provenance). Adding a rationale affordance or a team chip **moves those
+offsets**, so `specs/ROW-GRAMMAR.md` and the test must be amended **in the same commit** — per
+CLAUDE.md, that spec is LAW. That makes this a spec-amending change, not an additive mount, and
+the amendment needs its own slot decision (where does a rationale affordance sit in the grammar?
+where does a team chip sit relative to identity?).
+
+## WHAT IS SAFELY MOUNTABLE WITHOUT ANY OF THE ABOVE
+- **`reveal.js`** — wraps the row LIST, touches no StatStrip internals, no new data, no grammar
+  slot. This one is genuinely a mount.
+- **`teamChips.js`** — needs a grammar slot (it sits before the team abbr, inside identity), so it
+  is small but spec-touching.
+- **`rowRationale.js`** — needs the data threading AND the gating decision AND a grammar slot.
+
+## RECOMMENDATION
+Split D1-close into: **(1)** mount `reveal` now (no blockers), **(2)** a ROW-GRAMMAR amendment
+order that adds the team-chip slot + the rationale-affordance slot to the spec and test, and
+**(3)** the rationale mount, after the gating decision above is made.
+
+## TAGS
+VERIFIED: strip contract lacks reasoning; anon snapshot serves reasoning + kills; ROW-GRAMMAR
+locks source order. CANNOT DETERMINE: none. **BLOCKED: the rationale mount — on a
+gating decision (a/b/c) and a ROW-GRAMMAR amendment.**
