SwiftUI treated hostname prefixes such as fc.example.com and 10.example.com as local addresses. Connection details also maintained a separate, inconsistent copy of the policy.

Parse numeric addresses with Network's IPv4Address and IPv6Address, then classify their bytes. The shared policy recognizes private/link-local IPv4, loopback, IPv6 unique-local and link-local ranges, while retaining localhost and .local handling. Connection details strips ports/brackets and uses the same classifier.

The Swift target was rewritten to 285d2ab8. GitHub now reports conflicts. The native results below cover the earlier 157476f1 base; integration and native verification against the rewritten target remain pending.

Historical verification: native CI passed the new Core regression (27 host assertions plus error classification), the 12-case accept and 8-case reject matrices, and bare-IPv6 normalization. Its tested merge tree is identical to 229d43a against the earlier Swift target 157476f. Fresh independent review found no blocking correctness issue; it noted only that the new Core case follows the existing XCTest suite rather than the preferred Swift Testing framework.

This changes connection defaults and diagnostic classification without changing layout or controls. It does not establish live LAN/tailnet, permission-dialog, TLS or end-to-end IPv6 behavior. The inherited bracketed-host readiness issue is handled separately by #10738. No local native rerun is claimed.

Model and harness: GPT-6 / Codex (original implementation); GPT-6 Astra / Codex in T3 (readiness audit and description); GPT-6.1 Sol, high / Codex through T3 (fresh independent review).

- Cache EnvironmentStore's decoded document; publishes read it several
  times per second and previously hit disk + JSON decode every time
- Memoize parsed ISO8601 dates in NativeFeatureClient; every publish
  re-parsed ~10 timestamps per thread through two formatters
- Cache the mapped provider catalog per environment, invalidated on
  server config writes, instead of rebuilding hundreds of structs per
  publish
- Sort activity logs by raw ISO string instead of parsing dates inside
  the comparator (O(n log n) formatter calls per detail rebuild)
- Skip attachment hydration entirely for text-only threads
- Dedupe emitConnection so per-event yields only publish transitions
- Early-out acknowledgeDeliveredMessages when the outbox is empty
- Cap terminal buffers at 256KB; unbounded append could OOM on verbose
  commands and re-layout megabyte strings per chunk
- Key the markdown document cache by content fingerprint instead of the
  whole source string, stop inserting streaming intermediates (which
  churned completed messages out), and promote the final streamed render
  on completion instead of reparsing on the main thread
- Throttle streaming markdown renders (150ms leading-edge) instead of a
  200ms trailing debounce that never fired at an 80ms publish cadence,
  which left streaming messages as plain text for whole turns
- Share JSONEncoder/Decoder.t3 instances (were rebuilt per call) and
  skip sortedKeys on throwaway JSONValue bridging encodes
- Weak-capture the RPC connection loop and keepalive so released
  clients can actually deinit; snapshot dictionary keys before
  reentrant iteration in connected(); scope subscription Interrupts to
  the connection that assigned the request ID; add reconnect jitter
- Cache DPoP JWK + thumbprint (SHA-256 per managed request before) and
  the proof encoder; reuse ISO8601 formatter in command builders
- Replace crash-prone Dictionary(uniqueKeysWithValues:) on
  server-supplied IDs with first-wins reduces (model picker, agent
  awareness); retain per-thread states instead of full FeatureThread
  copies for transition signals; idle the home list timer to 60s when
  nothing is working

- Move table column-width estimation into the background render pass
  and store it on MarkdownRenderedTable; the view measured every cell's
  AttributedString per body evaluation on the main thread
- Make rendered markdown blocks Equatable (inline runs compare by
  reference thanks to the streaming run cache) and wrap block views in
  .equatable(), so only the changed tail of a streaming message
  re-renders instead of every block
- Gate the thread header's per-second TimelineView on working status;
  idle threads render a static status
- Decode local attachment previews off-main through the shared
  thumbnail cache; UIImage(data:) ran in body per reconfigure
- Memoize composer trigger parsing (was parsed 4x per keystroke)
- Drop markdown caches on memory warnings
- Stop the QR capture session on viewDidDisappear/backgrounding and
  resume on reappear; dismantle was the only stop path
- Retry pending workspace navigation requests when snapshot data lands
  so cold-start deep links are not silently dropped
- Scope approval/user-input resolution to details that contain the
  request instead of deep-comparing every cached transcript
- Binary-search diff hydration anchors (was O(n^2) on large files)

Note

🤖 GPT-6.1-Sol responding on behalf of Theo

Applied the focused fix to t3code/rebuild-mobile-app-swift in 97c2f23521. Closing this source PR after the port.

The source branch includes old rewrite history that conflicts with the current target. Only the intended fix and its focused tests were carried over.

The combined focused native checks passed: 241 tests, one existing skip, no failures.
