wtclaude c89e818dbf feat(asset-bridge): the transport, and the 357 wrong pictures it found
Asset Bridge phase 1 (docs/link/v8.md §16). Sidecar half: RunicGateway/link#41.
Docs half: RunicGateway/docs#236.

The transport for protocol 8, plus phase 0's validator promoted into the overlay
and extended to animations — which is where the interesting part is.

## 357 of the 1,144 "decodable" bodies are wrong pictures, on a STOCK client

Phase 0 measured the art path and left the animation half unbuilt. It has the same
defect, and it is worse: `GetAnimation` decodes through
`new MemoryStream(m_StreamBuffer, false)` — the whole shared buffer, not the
`length` bytes just read into it — so a truncated or absent record does not even hit
end-of-stream. It sails on into the previous animation's bytes.

Measured directly, because no count could tell:

| Decode body 320 (`lookup 22638982, length 0`) straight after… | Comes back |
|---|---|
| body 12, the dragon | the dragon, 176x167, identical hash |
| body 34, the wolf | the wolf's dimensions, 35x34 |
| body 400, the human male | the human, 27x63, identical hash |

The catalogue is **787 bodies, not 1,144**. Importing the other 357 would have written
duplicate creature portraits into the site showing whichever body the walk decoded
before them.

The record walk refused **0** real bodies on the stock client — the false-refusal
measurement §4.5 says the boundary depends on.

## And four of the twelve player bodies, not six

§5.2 listed the elf ghosts (607, 608) as decoding. Their index entry is `length 0`;
what came back was the elf female at her exact dimensions, because 606 is what the
walk decoded immediately before. Confirmed the same way — 607 after the dragon is
the dragon. Phase 4's UOP decoder now covers eight ids rather than six.

## What is here

- **`overlay/Scripts/Custom/Bridge/BridgeAssets.cs`** — the plane. Accepts on the Core
  thread, hands off to a dedicated asset worker, returns immediately. Three rules, all
  answering a specific failure:
  - **one slot**, second request answered `bridge.busy` (425). `Emit`'s queue is bounded
    in *lines*, so 10,000 queued 200 KB replies is 2 GB of shard memory; the bound that
    holds is flow control, on the side where the memory is.
  - **byte budgets** (`AssetBatchBytes`, 512 KiB) under the sidecar's new 1 MiB cap. The
    factor of two is load-bearing: a page always admits its first item, so it may
    overshoot by one, and the headroom is what makes that land on the wire.
  - **replies, never events** — no `reqId`, no answer. An uncorrelated frame is an event
    by definition, and §3.1 is why none of this may be one.
- **`PageBuilder`** — one paging envelope (`more`/`cursor`/`cut`) for all five families
  that will page, defined before the first one needs it. `cut` matters: "short page" has
  three meanings and only `end` means finished.
- **`assets.sources`** — stage 1 of the import gate, its first user.
- **`BridgeAssetValidator.cs`** — promoted from `tools/`, plus `ResolveAnimation` (the
  never-sweep-file-types rule as code, with no loop and no fallback),
  `AnimationRecordSane` and the frame walk.
- **`EXTRACTOR_VERSION`**, **`overlay.toml` protocol 7 → 8**, `AssetsEnabled`.

## Hashing had to come off the request path

§6's gate is (size, mtime) first, hash only when those differ. The first call has nothing
cached, so that still means hashing 1.06 GB — inside the sidecar's 10 s reply timeout it
does not fit. So hashes are computed on their own thread (deliberately not the single-slot
worker, which would answer every status poll `bridge.busy` for the whole pass) and the
reply carries `hashing`/`complete`.

Measured on the real rig: first call instant with `sha256: null`, second call **44 ms**
with every hash present.

## Verified on the wire, not just compiled

Real ServUO 57.4 + the real sidecar + the real client. `GET /assets/sources` → 200,
`X-UOLink-Version: 8`, `imaging: {ok: true}`, and §4.6's diagnostic firing on a live
client: `artDataFile: artlegacymul.uop`, with `art.mul` and `artidx.mul` both carrying
`shadowedBy`. Live events kept flowing through the new capped reader with no warnings.

Not exercised live: the disabled-plane 403 and the busy 425 (both unit-tested on the
sidecar side; the shard halves are a config read and a lock).

GuildRosterMembersPerLine=500

# one points.board frame per system when its top N moves.
#
# Slow on purpose: these are month-scale standings, and ten of the systems keep a row for

# coverage takes ceil(vendors / batch) x MarketSweepSeconds — 500 vendors at the defaults is one
# complete pass every 20 minutes, and the site labels the data with how stale it may be.
