# Changelog
## [1.40.0.0] - 2026-05-17
## **iOS QA on a real iPhone — no XCTest, no WebDriverAgent, no simulators.**
## **Bring your own Mac mini + Tailscale and you have a DIY device farm any agent can drive.**
Five new skills (`/ios-qa`, `/ios-fix`, `/ios-design-review`, `/ios-clean`, `/ios-sync`) bring the fork from `time-attack/gstack` into upstream with the hardening it needed to actually ship. The architecture's load-bearing insight: drop XCTest, drop the simulator, drop WebDriverAgent. Embed an HTTP server in the iOS app under test, drive it from a Mac-side bun daemon over the USB CoreDevice IPv6 tunnel. The agent reads your Swift source, codegens typed `@Observable` accessors via a SwiftPM swift-syntax tool (with a TS fallback for fast first-runs), deploys a debug bridge, and runs a closed find→fix→verify loop. With the optional `--tailnet` flag, the Mac daemon also binds Tailscale and accepts authenticated remote calls — your $500 Mac mini + an iPhone you already have replaces the BrowserStack line item.
### The numbers that matter
Source: 67 daemon unit/integration tests + 20 codegen tests + 8 high-level E2E tests, all running against a real bun process and a stubbed iOS StateServer.
| Surface | Fork as-is | Shipped |
|---|---|---|
| StateServer bind | `0.0.0.0:9999`, zero auth | `::1` + `127.0.0.1` only; bearer-token gate; boot token rotates within ~5s of daemon spawn so anything scraping `os_log` past then sees a dead credential |
| Release-build safety | none (any `#if DEBUG` mistake ships the bridge) | structural `Package.swift` `.when(configuration: .debug)` + CI `swift build -c release` invariant test that fails if the `DebugBridge` symbol appears |
| Codegen failure modes covered | regex breaks on computed properties, generics, multi-line types | swift-syntax AST (production), strict TS regex fallback for tests; 3 dedicated fixtures pin the known failure shapes |
| Multi-agent device contention | none | per-device session lock with sliding timeout on mutations only; concurrent `/session/acquire` race test |
| Remote control | not in scope | Tailscale identity-gated `/auth/mint`; capability tiers (observe/interact/mutate/restore); 1h default session TTL (24h cap); audit log of every authenticated mutating request; hashed-identity attempts log |
| Hardcoded paths | 3 `/Users/sinmat/.gstack/...` paths | none — all paths use `$HOME` / `os.homedir()` |
| Test coverage | none | 95 tests covering session-lock concurrency, snapshot/restore atomicity with schema-hash gate, identity canonicalization (user / tag / node-key), capability tier enforcement, rate limits, body-size limits, boot-token leak proofs, tailnet fail-closed probe, CoreDevice tunnel reconnect plumbing, cache-key composite (Swift version + tool git rev + source content + platform triple) |
### What this means for iOS developers
You can ship a SwiftUI app, add the `DebugBridge` SPM dep, run `/ios-qa`, and watch an agent drive your phone — taps, swipes, state writes, the whole loop. The "Driven by Claude Code" overlay confirms the device is agent-controlled in real time. Hand the box to a colleague over Tailscale and they can run QA from their laptop without touching the device. The Mac-side daemon enforces capability tiers, so the contractor who only needs to take screenshots can't write state; the CI runner that needs to set up a test scenario can do so without being able to call `/state/restore`. The audit log gives you per-request forensics. The structural Release-build guard means the bridge cannot ship to TestFlight even if a developer forgets `/ios-clean`.
### Itemized changes
#### Added
- **`/ios-qa`** (770-line SKILL.md.tmpl) — live-device QA flow with warm-start session cache, on-demand daemon spawn, Tailscale opt-in, demo + recording modes, full failure-mode + recovery matrix.
- **`/ios-fix`** — autonomous bug fixer that captures a reproducing `/state/snapshot` BEFORE editing source, then rebuilds + redeploys + verifies. Snapshot becomes a regression test fixture.
- **`/ios-design-review`** — 10-dimension Apple HIG audit on a real device. 0-10 scores per dimension with "what would make it a 10" framing, mirroring `/plan-design-review`'s rubric for browser.
- **`/ios-clean`** — convenience wrapper that strips `DebugBridge` SPM + `#if DEBUG` wiring. Explicitly NOT the safety-critical path — the structural Release-build guard in `Package.swift` is.
- **`/ios-sync`** — regenerates accessors against latest upstream gstack templates. Run after upgrading gstack or adding new `@Observable` classes.
- `ios-qa/templates/StateServer.swift.template` — dual-stack loopback bind (`::1` + `127.0.0.1`), boot token rotation, per-device session lock with mutation-only sliding window, snapshot/restore with schema envelope (`_schema_version` + `_app_build_id` + `_accessor_hash`), validate-then-apply atomicity via a single canonical-state-struct assignment, 1MB body cap.
- `ios-qa/templates/DebugOverlay.swift.template` — animated brand-colored border, agent attribution chip (`X-Agent-Identity` header, display-only, never trusted for auth), optional recording-mode watermark for screencasts.
- `ios-qa/templates/Package.swift.template` — DebugBridge target gated `.when(configuration: .debug)`. SwiftPM refuses to link in Release config.
- `ios-qa/daemon/` — Mac-side bun/TS daemon. Single-instance flock + readiness protocol, fail-closed tailscaled LocalAPI probe, dual-track `/auth/mint` (self-service for allowlisted identities, owner-granted via CLI), capability-tier allowlist on the tailnet listener, hashed-identity attempts log, every authenticated mutating tailnet request audited.
- `ios-qa/scripts/gen-accessors-tool/` — SwiftPM tool plugin using swift-syntax for production codegen.
- `ios-qa/scripts/gen-accessors.ts` — TS fallback for fast first-runs and CI. Same composite cache key (`sha256(source || swift_version || tool_git_rev || platform_triple)`) — codex flagged that source-only hash misses generator-logic changes.
- `ios-qa/docs/tailscale-acl-example.md` — runnable example covering tailscaled ACL setup, owner-mint flow, capability tiers, audit log structure, rate limits, and token lifetime.
- `test/skill-e2e-ios.test.ts` — 8 end-to-end scenarios covering codegen + daemon + stub StateServer + Tailscale gating + capability tiers.
- 67 daemon unit/integration tests across `session-tokens`, `allowlist`, `auth-mint`, `single-instance`, `tailscale-localapi`, `audit`, `proxy-classify`, `daemon-integration`.
- 20 codegen tests in `ios-qa/scripts/gen-accessors.test.ts` covering parse, cache key composition, cache hit/miss, 30d prune, and the 3 fork-regex-failure-mode fixtures.
#### Changed
- `test/helpers/touchfiles.ts` — registered `ios-qa-e2e` touchfile (gate-tier, fires when any `ios-*/` dir changes) so diff-based selection picks up iOS work.
- `AGENTS.md`, `docs/skills.md` — added "iOS device-farm" sections covering the five new skills.
#### Hardened (codex-flagged in the plan-review outside voice pass)
- iOS StateServer is loopback-only ALWAYS. Tailnet ingress is exclusively the Mac daemon's responsibility — the iPhone has no way to validate Tailscale identities, so identity validation MUST be Mac-side. The plan caught and removed an earlier contradiction that would have had the iOS app binding tailnet directly.
- Boot token rotates within ~5s of daemon spawn so anything scraping `os_log` past then sees a dead credential. The fork wrote the boot token to `os_log` once and used it for the daemon's lifetime — a durable-credential-in-logs smell.
- `/auth/mint` trust model split into two distinct mechanisms: self-service (caller must already be in allowlist) and owner-granted (CLI on the Mac writes to the allowlist file). Self-service NEVER auto-allowlists. The fork ambiguously mixed both paths.
- Snapshot envelope includes `_accessor_hash` so a snapshot captured against an older app build is loudly rejected with 409 schema_mismatch instead of silently corrupting state.
- `GET /state/snapshot` returns ONLY fields marked `@Snapshotable`. Default-deny instead of default-leak — keeps tokens, PII, and auth state out of agent visibility unless explicitly opted in.
- Tailnet listener fails closed if tailscaled LocalAPI is unreachable. Daemon refuses to open the tailnet listener at all rather than half-starting.
- `X-Agent-Identity` header is display-only. Never read for auth or for audit beyond the display chip — the daemon-minted token is what determines capability tier.
#### For contributors
- New SwiftPM tool dependency: `swift-syntax`. First run builds the dependency tree (2-5 min on a cold machine, ~50ms thereafter via content-hash cache). Document the "first-time setup" UX in `/ios-qa` so users know what's happening.
- The TS fallback in `ios-qa/scripts/gen-accessors.ts` is what tests + CI exercise. Production users get the Swift tool when available; CI never waits 5 minutes for swift-syntax to build.
- All daemon HTTP egress goes through `JSON.stringify(payload, sanitizeReplacer)` to strip lone UTF-16 surrogates before they reach the Anthropic API — mirrors `browse/src/sanitize-replacer.ts`. Tunnel-denial logging mirrors `browse/src/tunnel-denial-log.ts`. No new auth/logging primitives.
