 at a wall and tuning the geometry.** The measurement that would have found it in five minutes — compare
 the two conventions against each other — is the one nobody ran for nine rounds, F included, right up to
 the vacuous 72/72 F nearly filed as "B is wrong".

+## 28. Round 28 — v5.1 THE SPIKE AND THE SWEEP. **The sweep landed. The spike did not reach the game.**
+
+### ⚠ F's pose gate has NO SUBJECT — SKIPPED with the reason, per the law
+The brief: *"New-clip figure checks (lean/look poses through the scale gate), a bookmark spot-check
+(leaning peds in old frames)."* **There are no new poses in the game, so there is nothing to check:**
+- **`lean` does not exist.** E measured it rather than assumed it — the stash's 34 clips contain no
+  lean, and `find -iname "*lean*"` across ultra returns nothing. The brief and the kickoff both named it
+  as already-cached; **the premise was half wrong**, and E found it the only way anyone ever finds these:
+  by looking instead of trusting the list.
+- **`look.glb` is shipped, verified, published — and NOTHING BINDS IT.** `loadPedFleet()` loads
+  `walk.glb`, `idle.glb`, and `sit` (gated). No `look`. E's own handoff said it plainly: *"→ D: it's
+  ready. Gate it behind an opt the way rigs.js gates sit."* **D's entire R28 commit is
+  `LANE_D_NOTES.md` — 48 lines, docs only.** The run order said *"When E's clips land: D (#1 wiring)"*;
+  the log says **D committed BEFORE E shipped** (`afad68b` precedes `640bdbb`). Nobody was careless —
+  the wave order was, and the file on disk looks exactly like a delivered spike from every angle except
+  the one that matters.
+
+**The R17/R23 pattern, fifth appearance, and the cheapest one yet to have missed**: an asset on disk,
+verified, published to a public depot, sha1-checked by fetching the bytes BACK — and no consumer. Every
+check E ran was real and passed. None of them could see that nothing loads it. *A gate on the artifact
+cannot see the wire.*
+
+### So: v5.1 SHIPS, and it does not claim the spike
+Nothing is broken — an unbound clip is inert, the game is unchanged and correct. This is not R18's
+"known breach"; it is an **unfinished item**, and holding a polish tag over an inert file would be
+precious. **What ships is the sweep, and the tag says exactly that:**
+- **C's `audioEmitter`** — the till rings from the counter, the bed from the stage. C's own idea, parked
+  since R7, and C found its own v3.0 note had specified it wrong on both halves (*"the panner was
+  inert"*).
+- **Two items KILLED with the measurement** — B's awning ripple and D's instrument LOD, the oldest tri
+  item on the books. They don't leave the backlog "deferred"; they leave it **gone**, with the number
+  that killed them. *A backlog that only grows is a backlog nobody measures.*
+- **`look.glb`** — staged on the depot, and honestly described as staged.
+
+**Filed for R29 (D, one opt):** `rigs.js` gains `look` the way it gates `sit`; F passes it from the shell.
+Then the pose gate has a subject and F will run it. **v6 has not begun in-game — the tag must not say it
+has.**
