+          #
+          # The check above is VERSION-SCOPED: it only ever asks about the one
+          # version this run computed. That is enough to recover an orphan on
+          # the very next run, and useless afterwards — once any releasable
+          # commit lands, the next run computes a NEW version, never looks at
+          # the old tag again, and the orphan becomes permanent and silent.
+          #
+          # servuo-plugins v0.1.0 is the proof, and the proof is pointed: the
+          # commit that ADDED the recovery above was itself typed
+          # `fix(release): ... recover the orphaned v0.1.0 tag`, so it bumped to
+          # v0.1.1 — and the run that introduced the recovery stepped straight
+          # past the tag it was written to rescue. That tag is still orphaned.
+          #
+          # So every v* tag is checked, and anything missing a release is
+          # WARNED about. Deliberately not recovered: publishing an old version
+          # would mean building today's tree and shipping it under a tag whose
+          # tree it is not, which is worse than the inconsistency it fixes.

+    ///     ---------------
+    ///     BridgeSeeder builds a world at realistic SCALE, which is what the bridge needed:
+    ///     50 accounts, 150 characters, 30 houses, 30 vendors, 1,200 listings. It never needed
+    ///     the world to look like anything, so a vendor is "seed vendor" trading as
+    ///     "Seed Shop 810" and a character is "Seed004A". Every one of those names travels the
+    ///     whole bridge — plugin, sidecar, website — and lands on the marketplace, the guild
+    ///     roster and the housing pages, which are exactly the pages a screenshot wants.
+    ///
+    ///     This pass renames what is already there rather than seeding anything new. That
+    ///     matters: the data keeps its provenance. The prices, the listing counts, the decay
+    ///     stages, the fame and the skill sheets are all still whatever BridgeSeeder produced
+    ///     and whatever the shard has done to them since — only the strings a human reads are
+    ///     replaced. Nothing here invents shard state that the game did not produce.
+    ///
+    ///     IDEMPOTENT, AND DETERMINISTIC
+    ///     -----------------------------
+    ///     Names come from fixed tables indexed by the object's own serial, so the same vendor
+    ///     draws the same shop name on every run against the same save — screenshots retaken
+    ///     later still match. A second run is therefore a no-op, and a world half-dressed by an
+    ///     interrupted run finishes cleanly.
+    ///
+    ///     Shop and house names are also re-dressed when they are names THIS pass produced, so
+    ///     a change to the tables or to the hash can be applied to a world that has already been
+    ///     through here once. Character names are not: a person's name is an ordinary string
+    ///     with no closed set to recognise it by, so once dressed it is left alone.
+    ///
+    ///     WHAT IT ALSO DOES, AND WHY EACH IS HERE
+    ///     ---------------------------------------
+    ///     - Walks a few houses into IDOC, in two passes with a wait between them, because the
+    ///       website only records a collapse it watched happen. Decay is a live process: by the
+    ///       time anybody looks the stages have moved on and "Houses in danger" is empty. Empty
+    ///       is a true state and a poor screenshot, so this stages a handful — see PrimeIdoc.
+    ///     - Sets a known password on one seeded account. Logging a character in is the only
+    ///       way to make the online roster non-empty, and it needs a client, and a client needs
+    ///       a password. The seeder gives every account a random GUID nobody kept.
+    ///     - BUILDS GUILDS, which is the one thing here that creates rather than renames. The
+    ///       seeder never made any, so a shard behind these screenshots has an empty guild
+    ///       board and — because the website's Teams are reconciled from that board — no teams
+    ///       either. There is nothing to rename: a guild has to exist before it can be called
+    ///       something. Members are drawn from characters the seeder already made, so the only

+## Dressing a seeded world for screenshots
+
+`BridgeSeeder` builds a world at realistic **scale**, which is all the bridge ever needed. It does not
+build one that looks like anything: a vendor is `seed vendor` trading as `Seed Shop 810`, a character
+is `Seed004A`, a house sign says `Seed House 12`. Those strings travel the whole bridge and land on
+the marketplace, the guild roster and the housing pages of the website — fine for a protocol test,
+wrong for a screenshot.
+
+`BridgeDemoDress.cs` renames them in place. It seeds nothing: prices, listing counts, decay stages,
+fame and skills stay exactly as the seeder left them and as the shard has moved them since, so the
+data keeps its provenance and only the strings a human reads change. Names are drawn from fixed
+tables by a hash of each object's serial, so a re-run reproduces the same world, and shop and house
+names are re-dressed when they are names the pass itself produced — so a change to the tables can be
+applied to a world that has already been through here.
+
+```ini
+DemoDressOnStart=True
+DemoDressPassword=<a password you choose>
+```
+
+Boot once, then set `DemoDressOnStart=False`. The password is written to `seed_000` so a real client
+can log a character in — the only way to make the website's online roster non-empty — and it is read
+from the config rather than compiled in, so it never lands in source control.
+
+**It dresses seeded objects only, which means your own characters keep their names.** That is the
+right behaviour for a test shard and a thing to remember before pointing a camera at one: a dev
+world usually also holds the accounts, characters, guilds and houses of whoever built it, and those
+are real identifiers on a page that may end up public.
+
+**The sidecar's board is cached, so the website lags a rename.** A shop name reaches the site on the
+next market sweep, and a sweep advances `MarketSweepBatch` vendors per tick — 27 vendors at the
+defaults is two ticks. Allow a couple of minutes before concluding that a rename failed. This cost a
+debugging detour once: the shard had the new names all along and the sidecar was still serving the
+previous ones.
+

 `[seedworld` and `SeedOnStart` **write to the live world**. Copy `Saves/` somewhere outside the repo before running either. `Backups/Automatic` is rotated by `AutoSave.cs` and `Backups/Temp` is deleted outright, so neither is a safe destination.

 Seeded characters carry 8 items with ~6 mods each and ~12 trained skills. A real endgame character has more of both, so profile cost and payload are a **floor** — budget 2–4× for a fully-kitted character.

+## The login half needs a socket, not the sink
+
+`BridgeProtocol5Probe` fires `EventSink.InvokeAccountLogin` directly, which proves the REJECTED
+half of `account.login.result` and nothing more. ServUO's own `AccountHandler` calls
+`acct.HasAccess(e.State)` *before* it ever checks the password, and a null `NetState` fails that --
+so an in-process probe logs `Access denied` for a correct password too, and never produces an
+`accepted:true`.
+
+To prove the accepted half, speak the wire. A real socket also gives the frame a real `ip`, which
+is one of the fields being tested:
+
+```python
+# 4-byte seed, then 0x80 = [0x80][30b username][30b password][1b]
+s = socket.create_connection(('127.0.0.1', 2593))
+s.sendall(b'\x7f\x00\x00\x01')
+s.sendall(b'\x80' + pad(user) + pad(password) + b'\x5d')
+```
+
+The shard logs `Invalid password for '<acct>'` or `Valid credentials for '<acct>'`, and the sidecar's
+`/history?kind=account.login.result` should show `accepted:false reason:BadPass` and `accepted:true`
+respectively. **Both saying `accepted:true` is the bug the kind exists to prevent** -- it means the
+verdict was read inside the handler, before it existed.
+
+## Walking a house into IDOC needs a house that can decay
+
+Only a `Condemned` or `ManualRefresh` house decays. An `AutoRefresh` one -- and the owner's NEWEST
+house is always `AutoRefresh` -- has a `DecayLevel` getter that calls `ResetDynamicDecay()` and
+reports `Ageless`, so a forced `SetDynamicDecay` is wiped on the very next read, the sweep sees no
+change, and **nothing is emitted at all**. That looks exactly like a broken emitter. Filter on
+`house.CanDecay`, and expect a seeded world to have only one or two houses that qualify -- both
+probably already at IDOC, so the walk has to put one back down first.
+
+## A decaying house cannot be refreshed — only its owner coming back rescues it
+
+`BaseHouse.RefreshDecay()` returns `false` immediately when `DecayType == Condemned`, and on a
+seeded world **every house that can decay is Condemned** — the seeder backdates 18 accounts past
+`Account.InactiveDuration` precisely to make them decay. So `SetDynamicDecay(DecayLevel.LikeNew)`
+is wiped by the next read and `RefreshDecay()` does nothing: the sweep sees no change and emits
+nothing, which looks exactly like a broken emitter for the second time on the same page.
+
+The rescue is the OWNER LOGGING IN (`BridgeRigDriver`'s `activate <account>` reproduces it by
+setting `LastLogin`). What the shard then reports depends on how many houses that owner has:
+
+| the house | `DecayType` after the login | `DecayLevel` reads |
+|---|---|---|
+| their newest | `AutoRefresh` | **`Ageless`** — off the decay clock entirely |
+| any older one | `ManualRefresh` | **`LikeNew`** — back on the clock, at the top |
+
+Both are "out of danger", and the newest-house case is the common one. A consumer that watches only
+for `LikeNew` misses most rescues — which is what the engagement mapper did until this walk.
+
+## The console takes a fixed verb set, so `[commands` cannot be typed at a headless shard
+
+`Scripts/Misc/ConsoleCommands.cs` handles `save`, `shutdown`, `restart`, `online`, `kick` and a
+handful more; it does **not** dispatch arbitrary `[commands`. Every other probe here therefore runs
+either at boot or from an in-game client, and neither works for a walk driven from a script. That is
+what `BridgeRigDriver` and its `rigcmd.txt` are for.
+
+Also: only a CLEAN shutdown emits. `Stop-Process` drops the socket and the shard says nothing, so a
+killed shard is indistinguishable from a wedged one and `server.shutdown` never reaches the sidecar —
+use the driver's `shutdown` verb (`Core.Kill`) when the shutdown itself is what is being tested.
