Phase 5: [link account linking
BridgeAccountLink ties a game account to a website account. [link mints a one-time, 5-minute code from an unambiguous alphabet (no O/0/I/1), holds it in a Core-thread dict keyed to the account, and emits link.request. The website relays the code back through the sidecar as link.confirm; the shard validates, writes the WebsiteUserId account tag, and replies link.ok. A bad or expired code gets link.error. The tag persists to accounts.xml in ServUO's standard <tags> format, read by LoadTags at boot, so a link survives restarts with no new persistence layer. mob.login now carries webId when the account is linked, so the sidecar can attribute a session to a site user without a lookup. Safeguards: one-time codes; only the newest code per account is valid; per-account 30s rate limit against code spam; a 1-minute purge bounds the code table; the websiteUserId is trusted only because the socket is loopback-only. The tag reaches memory on confirm but disk only on the next save — a hard crash between loses it, and the player just re-runs [link. Verified end to end with a smart stub that reads the emitted code and confirms it: link.request -> link.confirm -> link.ok, a bad code -> link.error, and the tag observed in accounts.xml after a save. Evidence in docs/PLAN.md §15. The [link command body is exposed as RequestLink(Mobile) so it can be driven in tests without a client. Adds tools/stub_sidecar_link.ps1 and tools/scaffolding/BridgeLinkProbe.cs. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>

## 15. Phase 5 acceptance
|
||||
|
||||
`BridgeAccountLink.cs` implements `[link` and the inbound `link.confirm`. A player runs `[link`; the shard mints a one-time, expiring code (5 min TTL, unambiguous alphabet — no O/0/I/1), holds it in a Core-thread dict keyed to the account, and emits `link.request`. The player enters the code on the website; the sidecar sends `link.confirm`; the shard validates, writes the `WebsiteUserId` account tag, and replies `link.ok`.
|
||||
|
||||
Verified end to end with a smart stub (`tools/scaffolding/BridgeLinkProbe.cs` + a sidecar that reads the code and confirms it):
|
||||
|
||||
```
|
||||
<- link.request code=77M9TK account=seed_001 char=Seed001A ttlSec=300
|
||||
-> link.confirm code=77M9TK websiteUserId=web-9931
|
||||
<- link.ok code=77M9TK account=seed_001 websiteUserId=web-9931
|
||||
-> link.confirm code=BADCOD ...
|
||||
<- link.error code=BADCOD reason="unknown or expired code"
|
||||
```
|
||||
|
||||
**The tag persists.** After a `World.Save()`, `accounts.xml` contained:
|
||||
|
||||
```xml
|
||||
<tags>
|
||||
<tag name="WebsiteUserId">web-9931</tag>
|
||||
</tags>
|
||||
```
|
||||
|
||||
This is ServUO's standard account-tag format, read by `LoadTags` at boot, so the link survives restarts with no new persistence layer — as the plan promised.
|
||||
|
||||
Safeguards in place: codes are one-time and short-TTL; only the newest code per account is valid (a new `[link` drops prior codes); `[link` is rate-limited per account (30 s) against code spam; a 1-minute purge timer bounds the code table; and the `websiteUserId` is trusted only because the socket is loopback-only. `mob.login` now carries `webId` when the account is linked, so the sidecar can attribute the session without a lookup.
|
||||
|
||||
Note: the tag is written to memory on `link.confirm` but only reaches disk on the next world save (AutoSave, clean shutdown, or an explicit save). A hard crash between the two loses it — acceptable, since the player simply re-runs `[link`.
