Retire claims that have since shipped

[jeffcrouse]

CLAUDE.md loads into context every session, so a stale "what remains" isn't a tidy-up — it's a wrong instruction delivered on every turn.

Three stale claims

Said	Actually
ADR-0017: "What remains is familiar-apple: the WKWebView, the WKScriptMessageHandler… and the native unavailable state"	All shipped in familiar-apple #43; #53 brought the surface to the phone
ADR-0018: "0018 ships without Discover if 0019 is not accepted"	Both accepted and shipped (#44, #53)
ADR-0022: "Accepting 0022 is what makes #76 reversible, since 0020 point 3's bar for a third bridge message is cleared"	It didn't go that way

That third one is the one worth flagging. /library/discover/prompts turned out to be on the already-generated library tag, so Listening Ideas came back natively and the bridge stayed at two messages. Left as written, that sentence would have steered the next session into building the exact thing we deliberately chose not to build. It now says so explicitly: "The bridge stays at two messages. Do not add a third for this."

The ADRs carried it too

ADR-0017's own Implementation: block still read "Not yet built: the WKWebView host…". An accepted ADR is a living record — rule 6 protects the Decision, not the record of what shipped — so it's updated, and now also lists the three defects that surface has produced, all one shape: an affordance whose destination isn't mounted, failing silently (#70 zero-height lists, #74 the spinner, #76 Listening Ideas). That pattern is the useful thing to know before touching the embedded page again.

ADR-0022 had no Implementation: block at all. It gains one: what shipped, the three places the server didn't match its own documentation, and the empty-line SSE bug that its own recorded tradeoff predicted.

Also

• The Music Map ordering note was spent, so it now records that the map's interaction is still half-wired — the footer advertises scroll-to-zoom that was never implemented (MusicMapView.swift:370, and zero scroll handling in the file), zoomed(by:toward:) has exactly one caller (stepped()), and DragGesture(minimumDistance: 1) competes with click-to-focus. Verified against the source, not from memory.
• Key Files gains rows for the web chat and the embedded surface, neither of which had a pointer.

Verification

Every PR number, path and claim re-checked (rule 4). Two things that caught:

• useChatAvailability.ts was dropped from Key Files — it exists only in the open Don't offer chat when the server has no provider #78, so referencing it would have recreated exactly the staleness this PR removes.
• docs(adr): resolve ADR-0008's bundle identifier follow-up #55 and Don't offer chat when the server has no provider #78 are marked "open at the time of writing" rather than described as shipped, so this is accurate whatever order things merge in.
