Phase 3 is built and walked on a live shard. What the walk measured, and the
two places the design of record needed correcting:
§8.1, new: the catalogue is 787 exactly as §4.8 predicted, and the whole scan
of bodies 1-2047 takes 734 ms cold -- so the wall-clock paging §11 designed
never fires on this client. Every §4.8/§5.2 prediction held when the bytes were
rendered and LOOKED at: 320, 607, 608 and 666 come back absent rather than as
another creature's picture, and the direction split is 783 at index 1 against 4
at index 0 -- four player bodies, not six.
44 of the 787 hashes are shared by two or three bodies, which is the exact
signature of the wrong-picture bug, so it was chased rather than assumed. It is
the client's own Body.def aliasing (83 {1}, 84 {1}, 106 {12, 59}), and the check
that settles it is at the source: Translate(ref body, ref hue) rewrites `body`
only when bit 31 is set, unlike the one-argument overload -- and ResolveAnimation
calls that same two-argument overload, so validator and decoder resolve the
identical record.
§12.1, new: **§12 is right about the outcome and wrong about the mechanism.**
`shard_spawn_creatures` is emptied and refilled by every atlas refresh, and a
refresh runs on every boot -- so an imported filename written to that row is
destroyed by an ordinary re-parse of the ServUO tree, and the next Update finds
the client files unchanged and never restores it. Three tables outside that
blast radius, and the atlas import re-derives `art` on the way past.
§14: **§16 listed phase 3 as servuo-plugins + module-uo and that was wrong.**
web.rs routes every command explicitly, so `link` is in the phase. Corrected in
both places.
UOFIDDLER.md is DELETED, two phases earlier than §9.1 predicted -- creature art
was the only thing still on it. SPAWN_ATLAS.md §Artwork is rewritten around the
import, keeping the operator's own map as the thing that wins; the module's
SCHEMA.md gains the three tables and API.md the two admin routes.

Phase 2 of the Asset Bridge is built, so the documentation stops telling an
operator to install a GUI tool.
`v8.md` gains §9.1 and §9.2 — what the port cost, what it measured, and where the
base table comes from now. The measurement worth keeping: **67,496 rows in
290 ms**, which is exactly what UOFiddler's own `Ultima.dll` produced from this
same client through the converter this phase deletes. An independent
implementation agreeing to the row is the strongest check available that a format
decoder is correct, and it is not something a subtly-wrong one produces.
§17 records the four shapes the org lead settled before any of it was written.
Two departed from the recommendation: **the bridge always wins** (no source
setting — there is no version of that question an operator benefits from
answering) and **import is admin-triggered** (boot does not call the shard at
all).
`CLILOCS.md` is rewritten around that: where the table comes from, what arrives
and in how many pieces, the refusals — including the two the file pipeline had no
equivalent of (a client patched mid-import, and the base's exemption from the
vanished-source rule, which exists so an upgraded install is not asked to approve
a change the upgrade itself made).
`UOFIDDLER.md` loses Part 1 entirely rather than having it rewritten. What is
left is creature art, which phase 5 takes, after which the page goes away. `v3.md`
§8.6 keeps its reasoning with a note saying what superseded it, because the
argument for why the manual step existed is still the argument for why this was
worth building.

Phase 4 slice 4. BACKEND_DESIGN.md had never been de-UO'd: Phase 3 rewrote core's
code and README, but §5.2's identifier check reads code, not prose, so nothing
ever looked at the design document. It still described 27 shard_* tables, 20 UO
route rows and the shard visibility ladder as core's, a phase after core stopped
being able to serve any of them.
Moved, text unchanged:
BACKEND_DESIGN §3 six shard_* schema sections (226 lines) → modules/uo/SCHEMA.md
BACKEND_DESIGN §4 13 public + 7 admin UO route rows → modules/uo/API.md
BACKEND_DESIGN §6.5 the audience ladder (70 lines) → modules/uo/API.md §4
Core keeps the seam and gains the eight /admin/modules routes it had never
documented. §6.5 becomes "Module-owned audience boundaries": core's security
boundary ends at authentication, roles and the session, and a module that serves
game data brings its own.
Also fixed on the way: users.router.js was still listed as 15 routes (it is 9 —
six went to the extension slot), and the push section still promised
config/shardStreams.js "moves out with it" four slices after it left.
The acceptance table now carries results. Criterion 2 was proved for real against
module-uo v0.3.0 on an empty database, which turned up the uninstall ordering
defect fixed in website#146.

Records the slice that closes the extraction, and adds the two documents phase 3
owed: docs/modules/uo/ and the module-rust dry run.
**The slice found an obligation neither repo had built.** MODULE_API.md §2.8 and
§6.1a settle the OpenAPI fragment in detail — a module ships one, core merges the
fragments of started modules into /api/docs.json. Neither half existed, so the 72
URLs module-uo serves were in no spec at all. §2.8 and §6.1a now record what was
built, including the four things settled while building it: the filename is fixed
rather than declared, a module namespaces what it DEFINES and references core's
shared schemas by core's name, the generator derives its prefixes from the
module's own register() call, and swagger-autogen's diagnostics have to be
captured because it reports a broken annotation and then prints Success.
**§5.3 gains the design decision the frozen manifest actually made:** it is a
SUBTRACTION, not a prefix filter. Generating the manifest without the module and
then with it answers "what does the module serve" AND "did core lose anything",
and the second is the one §1.2 promises to the shipped Android app. A module that
shadowed a core route cannot appear as an addition anywhere.
**BACKEND_DESIGN.md §4.0.1** is new: /api/docs.json is assembled per request, the
two generated artifacts are core's alone, and the route count was still 228.
**docs/modules/** is new, per §2.10 (module documentation aggregates here, not in
module repos): docs/modules/uo/README.md orients a reader on what module-uo
serves, owns and needs from an operator, and links out to the feature docs that
already existed rather than restating them.
**docs/modules/rust-dryrun.md** is phase 3's fourth acceptance criterion. A
written, deliberately unimplemented module for Rust — chosen because it wipes
monthly, runs several servers rather than one shard, identifies by Steam, and
ships RCON so there is no sidecar to write. The contract generalises: same
manifest, same seven registration calls, same schema rules, and six of the UI
kit's seven members wanted by a game with nothing in common with the one the kit
was curated from.
It found one real gap — **a module cannot register an identity provider**, and
"Sign in with Steam" is what a Rust community expects. Recorded as the first
candidate for a future MODULE_API_VERSION bump rather than bolted on: an identity
provider participates in session creation, and §2.7's link-only SSO policy has to
survive it.
Also: website-README.md refreshed from the repo (it was several changes stale),
and three settled decisions added (18-20).
Pairs with Module-uo#6 and website#141.
