docs(market): close Gap 1 — active seller row under forSale is live-confirmed

The one claim the Fix B promotion left open: no active listing existed during
that session, so only the expired path had been exercised.

Closed with a disposable card (75 ST, res 212188, wire id 100000178 — one of
three identical copies, not in the squad) listed through the real FIFA 17 client
at 150/200 for 1h, so expiry arrives naturally. No timestamp touched.

Wire: itemState=forSale, tradeState=active, 12 atoms, prices intact, expires
3562 -> 3556 over a 6s sample (live clock), /trade/status coherent, counts
{count:1, selling:1}, coins unchanged, zero inactive rows (Fix A intact).

The decisive evidence is client-side, not ours: a read-only /proc/<pid>/mem
decode of the live trade-pile auction record returned
  itemState=5(forSale)
on the very field that read -1(<unrecognised>) under listFS. Direct A/B on the
only changed field, taken from the client's own memory.

Operator confirmed the row renders under LISTED ITEMS with correct prices, a
counting-down timer, normal art, and correctly non-actionable while active.

No code change required — the promoted implementation was already correct on the
active path. Claim boundary unchanged: this proves the client DECODES the token
and says nothing about the Flash action-gate term.

+### Gap 1 CLOSED — an ACTIVE seller row under `forSale` (2026-08-17)
+
+The one thing the Fix B promotion could not test, because no active listing existed
+during that session. Closed with a deliberately disposable card: a **75 ST**, resourceId
+`212188`, wire id `100000178` — one of **three identical owned copies**, not in the
+11-man squad, `untradeable: false`, discardValue 600. Listed **through the real FIFA 17
+client** at Start 150 / Buy Now 200 for the shortest offered duration (1h), so expiry
+would arrive naturally. No timestamp was touched.
+
+Listing creation was entirely Rust-owned:
+`PUT …/item` (club → pile) → `route=market-list POST item_id=100000178 listed=true
+trade_id=1000000178` → `POST …/auctionhouse 200`, then the client polling
+`GET …/trade/status?tradeIds=1000000178` (`requested=1 returned=1`) for the row it draws.
+
+Wire, active row `1000000178`
+(`docs/evidence/market-lifecycle-2026-08-17/gap1-active-forsale.json`):
+
+| Field | Value |
+|---|---|
+| `itemState` | **`forSale`** |
+| `tradeState` | `active` |
+| `startingBid` / `buyNowPrice` / `currentBid` | 150 / 200 / 0 |
+| `bidState` | `none` |
+| `expires` | **3562 → 3556** over a 6-second sample — a live clock, not a frozen scalar |
+| atom count | **12**, exactly what `0x18013e410` reads |
+| `itemData` | full card, 6-entry `attributeList` |
+| `/tradePile/counts` | `count 1, selling 1, offered 0, sold 0` |
+| coins | 29,843,976 unchanged |
+| Fix A | 0 `inactive` rows |
+
+`/trade/status` stayed coherent with `/tradePile` throughout, agreeing on tradeId,
+`active`, `forSale` and a decreasing `expires`.
+
+**The decisive observation** is not the wire — it is what the client made of it. A
+read-only `/proc/<pid>/mem` decode of the live trade-pile auction record (slide proven by
+FNV control MATCH first; `O_RDONLY` + `pread` only) returned:
+
+```text
+tradeId=1000000178 state=1(active) bid=0(none) buyNow=200 start=150 cur=0 expires=3457
+item CARD_ID=212188 cardType=1 tradeable=1 itemState=5(forSale) pile=0 rating=75
+```
+
+`itemState = 5(forSale)`. The same field read `-1(<unrecognised>)` under `listFS`. This is
+the direct A/B on the only changed field, taken from the client's own memory rather than
+from our response — the strongest form of this evidence available without AVM1 work.
+`pile = 0` again, confirming pile is still never set from the wire.
+
+Operator UI acceptance: card under **LISTED ITEMS** (not the TRANSFER LIST section), Start
+150 / Buy Now 200 correct, **Time Remaining visibly counting down**, normal card art, no
+malformed row, no duplicate, no premature Expired, no crash, and correctly
+**non-actionable while active**. The client's container populating with exactly this row
+(`rows=1`) independently corroborates that the Transfer List screen bound and drew it.
+
+**No code change was required** — the promoted implementation was already correct on the
+active path, which is what the test was designed to find out.
+
+Two process notes worth keeping. First, an early capture reported "countdown NO"; that was
+a bug in the capture script (it re-read a hardcoded copy id rather than the row it had
+resolved), not a server fault — the same run's `/trade/status` already showed a lower
+`expires` than `/tradePile`. Verify the instrument before believing a negative. Second,
+the client's auction-record containers read **0 rows** while the operator was on any other
+screen; they populate only while the Transfer List is bound. An empty container is not
+evidence of an empty pile.
+
+**Claim boundary unchanged:** this proves the client *decodes* the token. It says nothing
+about the Flash action-gate term.
