[build-tools] Free evicted Android log files early and close uncapped files

Serialize each file's I/O through one queue so a fully evicted file is
truncated as soon as its queued writes land, live or finished. Evict the
least recently written file first. Seal uncapped files when their stream
finishes and close the handle even when sealing fails.

+# Changesets
+
+Every PR that changes a package adds a changeset: a Markdown file in this directory that names the changed packages, the bump type, and a one-line summary for the changelog. Do not edit `CHANGELOG.md` files. The release generates them from the changesets.
+
+## Add a changeset
+
+```sh
+yarn changeset
+```
+
+Select the changed packages and the bump type, then write the summary. Commit the new file with your PR. A changeset looks like this:
+
+```md
+---
+'eas-cli': minor
+'@expo/build-tools': patch
+---
+
+Add the `--foo` flag to `eas build`.
+```
+
+Write the summary as one sentence in the style of the existing `CHANGELOG.md` entries. The release adds the PR link and the author, and prefixes the entry with the package directories, for example `[eas-cli][build-tools]`.
+
+## Bump types and changelog sections
+
+All packages share one version. The highest bump in all changesets sets the next version. Each entry goes into the root `CHANGELOG.md` section for its highest bump:
+
+| Bump    | Root `CHANGELOG.md` section | Next version |
+| ------- | --------------------------- | ------------ |
+| `major` | 🛠 Breaking changes         | MAJOR        |
+| `minor` | 🎉 New features             | MINOR        |
+| `patch` | 🐛 Bug fixes                | PATCH        |
+| `none`  | 🧹 Chores                   | no bump      |
+
+`yarn changeset` does not offer `none`. For changes that should not appear in the changelog, add the "no changelog" label to the PR in GitHub.
+
+The "no changelog" label skips the changeset check, but not the `CHANGELOG.md` check. A PR that edits a `CHANGELOG.md` file always fails. Dependabot PRs skip the changeset check.
+
+See [RELEASING.md](../RELEASING.md) for how a release uses the changesets.

+## Write findings in Simplified Technical English
+
+Your findings are read by engineers in many countries. Many of them do not speak
+English as a first language. Write every piece of prose you emit — `title`,
+`rationale`, `suggestion` — under the ASD-STE100 Simplified Technical English
+rules:
+
+- **One word, one meaning.** Choose one term for a thing and reuse it. Do not
+  alternate between synonyms for the same object ("the handler" / "the callback"
+  / "the hook").
+- **Short sentences.** Use 20 words or fewer. Split a long sentence into two.
+- **Active voice.** Write "the parser drops the flag", not "the flag is dropped
+  by the parser". Name the actor.
+- **Plain words.** Write "use", not "utilize"; "before", not "prior to";
+  "because", not "due to the fact that". Remove hedges ("arguably", "it seems
+  that") and intensifiers ("very", "extremely").
+- **One topic per paragraph.** Keep paragraphs short.
+- **No idiom, metaphor, or sarcasm.** State what happens.
+
+This rule is about prose only. `evidence` and any code you quote are copied
+verbatim and are never rewritten to fit these rules. Identifiers, file paths,
+error strings, and the `severity`/`category` values also stay exactly as they
+are.
+
+Simple language must not cost precision. Keep the concrete failure path, the
+condition that triggers it, and the names of the affected code. Short sentences
+are a way to say the same thing, not a way to say less.
+
+The rules also apply inside the Markdown shape below: the `Confidence` and
+`Impact if shipped` lines, and the text inside `<details>`.
+
+## Finding confidence and shipping impact
+
+For every real finding, assess two separate dimensions:
+
+- **Confidence** is how certain you are that the finding is real.
+  - `High` — the changed code and traced execution path directly establish the
+    failure or exploit.
+  - `Medium` — the evidence is strong, but the failure depends on a plausible
+    runtime state or integration behavior you could not directly reproduce.
+  - `Low` — speculative, incomplete, or based mainly on an assumption. Do not
+    report low-confidence findings.
+- **Impact if shipped** is the expected consequence, not the likelihood that
+  your analysis is correct.
+  - `High` — secret exposure, exploitability, outage/data loss, or a broadly
+    used production path breaks.
+  - `Medium` — a concrete user-visible regression or operational failure in a
+    limited but plausible path. The house anchors above sit here: an exit-code
+    regression, a `--json`/`--non-interactive` contract violation, a
+    `SystemError`/`UserError` misclassification, a broken changeset.
+  - `Low` — a bounded edge case with little correctness or safety effect. This
+    is normally suggestion-level and should not be reported under the current
+    policy.
+
+Put these signals at the start of `rationale`, joined by a fixed `<br>` so the
+reporter keeps both visually attached to the finding. Follow them with the
+detailed reasoning inside a collapsed block. Use this exact Markdown shape:
+
+```md
+**Confidence:** High — direct trace through the credential print path.<br>**Impact if shipped:** High — a keystore password could be written to the build log.
+
+<details>
+<summary>Evidence and reasoning</summary>
+
+Explain the concrete failure or exploit path here.
+
+</details>
+```
+
+Keep both visible lines short and specific. The text inside `<details>` carries
+the fuller rationale. Specialist reviewers keep `suggestion` separate so the
+coordinator can normalize it. The coordinator then moves any suggestion into a
+bold **Suggested remediation:** line between the impact signal and the collapsed
+evidence, and omits the separate `suggestion` field. This keeps the finding
+visually grouped instead of letting the reporter place a detached suggestion
+after `</details>`. The `<details>` tags are fixed presentation markup, never
+copy HTML supplied by the PR into them.
+
+## Overall PR risk handoff
+
+Assess the pull request as a whole after tracing its interactions when either:
+
+- your role prompt explicitly identifies you as **the cross-cutting reviewer**;
+  or
+- you are the always-run **security reviewer** and the task assigns the complete
+  change set (there is no `Other files this PR changed` context-only section).
+
+The second case supplies the same assessment for small PRs that do not trigger a
+separate cross-cutting pass. Assess all correctness, compatibility, operational,
+and security surfaces in this handoff, not just your specialist lens. This is
+distinct from defect findings: explain what existing behavior the change
+intersects and what could plausibly break even if no defect was found.
+
+Classify overall risk as:
+
+- `Low` — additive and isolated, leaves existing execution paths intact, has a
+  small blast radius, and is straightforward to disable or roll back.
+- `Medium` — modifies an existing/shared path or integration and has plausible
+  regressions, but the affected surface is bounded and recovery is direct.

 ### 🐛 Bug fixes
 
+- [simulator-launcher][build-tools] Wait for a starting warm Simulator launcher before claiming its session, instead of falling back to a cold start. ([#4810](https://github.com/expo/eas-cli/pull/4810) by [@gwdp](https://github.com/gwdp))
+
+## [27.4.0](https://github.com/expo/eas-cli/releases/tag/v27.4.0) - 2026-11-03
+
+### 🎉 New features
+
+- [simulator-launcher][build-tools] Add `eas/start_warm_appium_remote_session`, which runs the Appium session on the warm Simulator, or starts cold. An `appium` claim stops the unused tools first, so WDA does not share the Simulator with the agent-device runner. ([#4735](https://github.com/expo/eas-cli/pull/4735) by [@gwdp](https://github.com/gwdp))
+- [build-tools] Add warm iOS session steps (`eas/start_warm_serve_sim_remote_session`, `eas/start_warm_agent_device_session`, `eas/start_warm_argent_remote_session`). They run the existing session on the warm Simulator, or start cold. `eas/start_agent_device_session` also accepts `install_app_path` and `launch_app_identifier`. ([#4723](https://github.com/expo/eas-cli/pull/4723) by [@gwdp](https://github.com/gwdp))
+- [build-tools] Update the app version and build number from the final application archive, so the build shows the values the native build resolved. ([#3499](https://github.com/expo/eas-cli/pull/3499) by [@kadikraman](https://github.com/kadikraman))
+
+### 🐛 Bug fixes
+
+- [build-tools] Upload the final agent-device session artifacts before stopping the daemon, including sessions that reuse a warm Simulator. ([#4750](https://github.com/expo/eas-cli/pull/4750) by [@gwdp](https://github.com/gwdp))
+- [build-tools] Add internal helpers that claim the warm Simulator through the launcher and adopt it on the warm serve-sim. Skip the Expo Go install when the warm Simulator already has the same Expo Go version. ([#4724](https://github.com/expo/eas-cli/pull/4724) by [@gwdp](https://github.com/gwdp))
+- [build-tools] Recover warm Simulator recordings when their MP4 exists before the shutdown manifest is ready. ([#4789](https://github.com/expo/eas-cli/pull/4789) by [@gwdp](https://github.com/gwdp))
+- [eas-cli] Show the Expo Simulators hint after a successful build from November 10 instead of November 5. ([#4801](https://github.com/expo/eas-cli/pull/4801) by [@williamgrosset](https://github.com/williamgrosset))
+
 ### 🧹 Chores
 
+- [build-tools] Move iOS Simulator startup behind a shared session host contract. ([#4752](https://github.com/expo/eas-cli/pull/4752) by [@gwdp](https://github.com/gwdp))
+
+## [27.3.0](https://github.com/expo/eas-cli/releases/tag/v27.3.0) - 2026-11-02
+
+### 🎉 New features
+
+- [eas-build-job] Add optional Observe error context to workflow jobs. ([#4787](https://github.com/expo/eas-cli/pull/4787) by [@AbbanMustafa](https://github.com/AbbanMustafa))
+
+### 🐛 Bug fixes
+
+- [eas-cli] Bump `@expo/apple-utils` to `2.3.0` to fix iOS capability sync when App Store Connect rejects enabling, disabling or changing a capability. ([#4790](https://github.com/expo/eas-cli/pull/4790) by [@douglowder](https://github.com/douglowder))
+- [eas-cli] Keep already linked App Groups, Merchant IDs and iCloud containers when capability sync links another identifier. ([#4584](https://github.com/expo/eas-cli/pull/4584) by [@ceydaakin](https://github.com/ceydaakin))
+- [worker] Mask secrets in every record the worker process writes to its stdout: the build log records and the worker's own records. ([#4782](https://github.com/expo/eas-cli/pull/4782) by [@hSATAC](https://github.com/hSATAC))
+- [worker][build-tools] Stop warmup in the background for jobs that do not use the warm Simulator, so job setup does not wait for it. Before build-tools boots or clones a Simulator, it waits until the launcher's state file records that cleanup finished, and fails if cleanup does not finish in time. ([#4721](https://github.com/expo/eas-cli/pull/4721) by [@gwdp](https://github.com/gwdp))
+- [build-tools] Recover unhealthy device-session tunnels without changing their URLs and block further traffic when shutdown starts, even if ngrok cleanup times out. ([#4526](https://github.com/expo/eas-cli/pull/4526) by [@gwdp](https://github.com/gwdp))
+- [build-tools] Stop sending the SSH host when registering an SSH session. ([#4784](https://github.com/expo/eas-cli/pull/4784) by [@AHGIJMKLKKZNPJKQR](https://github.com/AHGIJMKLKKZNPJKQR))
+
+## [27.2.0](https://github.com/expo/eas-cli/releases/tag/v27.2.0) - 2026-10-29
+
+### 🎉 New features
+
+- [build-tools] Use single-device previews when the session already has a valid device ID. ([#4733](https://github.com/expo/eas-cli/pull/4733) by [@gwdp](https://github.com/gwdp))
+- [eas-cli] Add an experiment that suggests Expo Update to coding agents after a build when the Free plan account is within 5 builds of the platform limit. ([#4758](https://github.com/expo/eas-cli/pull/4758) by [@williamgrosset](https://github.com/williamgrosset))
+- [eas-cli] Add `eas observe:traces` to list request trace spans (or a summary of span names and counts), `eas observe:trace` to display one trace as a span tree, and span rows in the `eas observe:session` timeline. ([#4772](https://github.com/expo/eas-cli/pull/4772) by [@kadikraman](https://github.com/kadikraman))
+- [simulator-launcher] Accept a comma-separated list of warm Simulators in `EXPO_SIMULATOR_DEVICE`; the first is the default. One serve-sim serves every listed device on one port. After the default device is ready, warmup preinstalls the latest stable Expo Go from one download and tries to disable apsd on the other devices, until a job claims one. A claim can select any listed device and reports its preinstalled Expo Go. ([#4764](https://github.com/expo/eas-cli/pull/4764) by [@gwdp](https://github.com/gwdp))
+- [simulator-launcher] Add `@expo/simulator-launcher`, which warms an iOS Simulator at VM boot and hands it to one EAS job (`start`, `claim`, `prepare-tools`, `stop`). ([#4722](https://github.com/expo/eas-cli/pull/4722) by [@gwdp](https://github.com/gwdp))
+- [eas-cli] Show a one-time Expo Simulators hint after a successful build. ([#4768](https://github.com/expo/eas-cli/pull/4768) by [@FiberJW](https://github.com/FiberJW))
+- [vm-tools] Add a macOS startup script loader that runs `/usr/local/share/vm-tools/startup.sh` once per VM boot. ([#4725](https://github.com/expo/eas-cli/pull/4725) by [@gwdp](https://github.com/gwdp))
+
+### 🐛 Bug fixes
+
+- [build-tools] Explain missing background task identifiers reported by App Store Connect. ([#3465](https://github.com/expo/eas-cli/pull/3465) by [@sjchmiela](https://github.com/sjchmiela))
+- [build-tools] Explain App Store Connect NOT_AUTHORIZED responses in the shared API client. ([#3462](https://github.com/expo/eas-cli/pull/3462) by [@sjchmiela](https://github.com/sjchmiela))
+- [build-tools] Explain App Store Connect UNEXPECTED_ERROR responses in the shared API client. ([#3467](https://github.com/expo/eas-cli/pull/3467) by [@sjchmiela](https://github.com/sjchmiela))
+- [build-tools] Explain missing app icons reported by App Store Connect, including codes 90022 and 90023, while preserving Apple’s validation details. ([#3466](https://github.com/expo/eas-cli/pull/3466) by [@sjchmiela](https://github.com/sjchmiela))
+- [build-tools] List failed Google Play commit attempts in order, including network failures, when the outcome is uncertain. ([#4660](https://github.com/expo/eas-cli/pull/4660) by [@sjchmiela](https://github.com/sjchmiela))
+- [worker] Run package-manager version queries in parallel during worker preparation. ([#4710](https://github.com/expo/eas-cli/pull/4710) by [@gwdp](https://github.com/gwdp))
+- [worker] Start the Xcode version check in the background during worker tool preparation. Apply the Xcode 26.0 upload workaround when the query finishes, without delaying job startup. ([#4707](https://github.com/expo/eas-cli/pull/4707) by [@gwdp](https://github.com/gwdp))
+- [build-tools] Fix a five-minute cleanup delay when a device session is canceled during startup and its screen recorder fails before connecting. ([#4761](https://github.com/expo/eas-cli/pull/4761) by [@gwdp](https://github.com/gwdp))
+- [eas-cli] Remove the Free plan build limit guidance experiment for coding agents from `eas build`. ([#4757](https://github.com/expo/eas-cli/pull/4757) by [@williamgrosset](https://github.com/williamgrosset))
+- [worker] Allow jobs to skip installing the CocoaPods cache proxy with EAS_BUILD_DISABLE_COCOAPODS_CACHE_PLUGIN=1. ([#4709](https://github.com/expo/eas-cli/pull/4709) by [@gwdp](https://github.com/gwdp))
+- [build-tools] Handle TURN requests for a stopped device session without reporting a warning. ([#4762](https://github.com/expo/eas-cli/pull/4762) by [@gwdp](https://github.com/gwdp))
+- [build-tools] Preserve indented and incomplete Xcode compiler errors in formatted build logs, including the final diagnostic when logging stops. ([#4365](https://github.com/expo/eas-cli/pull/4365) by [@sjchmiela](https://github.com/sjchmiela))
+
+### 🧹 Chores
+
+- [simulator-launcher] Add the state, request command and service helpers for the warm Simulator launcher. The package stays private until #4722 adds its CLI entry point. ([#4766](https://github.com/expo/eas-cli/pull/4766) by [@gwdp](https://github.com/gwdp))
+
+## [27.1.0](https://github.com/expo/eas-cli/releases/tag/v27.1.0) - 2026-10-28
+
+### 🎉 New features
+
+- [eas-cli] Display queued workflow runs: `workflow:run --wait` and `workflow:status` show a run waiting for its concurrency group and the run blocking it, and `workflow:cancel` includes queued runs in its selection list. ([#4258](https://github.com/expo/eas-cli/pull/4258) by [@hSATAC](https://github.com/hSATAC))
+- [eas-cli] Upload the workflow files that `uses` jobs reference, including nested ones, when running a local workflow file with `eas workflow:run`. ([#4769](https://github.com/expo/eas-cli/pull/4769) by [@sswrk](https://github.com/sswrk))
+
+### 🐛 Bug fixes
+
+- [build-tools] Explain App Store Connect error 90189 as a duplicate build number. ([#3461](https://github.com/expo/eas-cli/pull/3461) by [@sjchmiela](https://github.com/sjchmiela))
+- [eas-cli] Fail the command when EAS CLI cannot pull environment variables from EAS servers, instead of continuing without them. ([#4774](https://github.com/expo/eas-cli/pull/4774) by [@wschurman](https://github.com/wschurman))
+- [eas-cli] Format the generated root changelog before committing a release. ([#4773](https://github.com/expo/eas-cli/pull/4773) by [@gwdp](https://github.com/gwdp))
+- [build-tools][worker] Put the `NPM_TOKEN` registry credential in the builder's npm user config on EAS Build (`~/.npmrc`, or the file `NPM_CONFIG_USERCONFIG` names), where pnpm 10.34.2+ and 11.5.3+ still expand `${NPM_TOKEN}` (they ignore it in a project-level `.npmrc`). Explain what to change when the project's pnpm version needs a newer Node.js than the build runs, including when eas.json sets `node` or `pnpm`. ([#4729](https://github.com/expo/eas-cli/pull/4729) by [@hSATAC](https://github.com/hSATAC))
+- [build-tools] Install `@expo/repack-app` for the `eas/repack` step with npm in a sandbox that sees only `PATH` and its own `HOME`, so the build machine's npm and Yarn configuration cannot break the install, fetch it through the EAS npm cache when the job uses one, and show the installer output in the build log. The step no longer looks the version up separately before installing. When the npm cache fails, the install retries against the public registry like the project install does; the `eas/run_agent` agent CLI install shares the same helper and gains the same retry. ([#4728](https://github.com/expo/eas-cli/pull/4728) by [@hSATAC](https://github.com/hSATAC))
+- [eas-cli] Honor the `--non-interactive` flag in `workflow:cancel`; it was parsed but never applied, so automation could hang on the interactive picker. ([#4258](https://github.com/expo/eas-cli/pull/4258) by [@hSATAC](https://github.com/hSATAC))
+- [eas-cli] Stop reporting a finish time for workflow runs that have not finished: `workflow:runs` reports `finishedAt` only for runs in a final status. ([#4258](https://github.com/expo/eas-cli/pull/4258) by [@hSATAC](https://github.com/hSATAC))
+
+## [27.0.0](https://github.com/expo/eas-cli/releases/tag/v27.0.0) - 2026-10-27
+
+### 🛠 Breaking changes
+
+- [eas-cli] Write the reason a command failed to stderr, next to the `command failed.` line, instead of to stdout. A program that reads the reason from stdout must read stderr instead. ([#4592](https://github.com/expo/eas-cli/pull/4592) by [@vonovak](https://github.com/vonovak))
+
+### 🎉 New features
+
+- [eas-cli] Send the `permissions.account.role` from the build profile to request a role for the build's `EXPO_TOKEN`. ([#4734](https://github.com/expo/eas-cli/pull/4734) by [@wschurman](https://github.com/wschurman))
+- [eas-cli] Add `simulator:logs` to read and follow logs from an iOS simulator session and download saved logs after it stops. ([#4545](https://github.com/expo/eas-cli/pull/4545) by [@gwdp](https://github.com/gwdp))
+
+### 🐛 Bug fixes
+
+- [build-tools] Keep the launched app open when an Appium iOS session starts. ([#4699](https://github.com/expo/eas-cli/pull/4699) by [@gwdp](https://github.com/gwdp))
+- [build-tools] Run Appium through the prepared Full Disk Access helper when available on macOS. ([#4622](https://github.com/expo/eas-cli/pull/4622) by [@gwdp](https://github.com/gwdp))
+- [eas-cli] Show permission guidance, including `permissions.account.role` in eas.json, when a build request fails with an authorization error. ([#4760](https://github.com/expo/eas-cli/pull/4760) by [@wschurman](https://github.com/wschurman))
+- [eas-cli] Print the notice about eas-cli in project dependencies only when stderr is a terminal, so programs that read stderr get the command's error. ([#4591](https://github.com/expo/eas-cli/pull/4591) by [@vonovak](https://github.com/vonovak))
+- [eas-cli] Show account roles and credential permission limits in `eas login` when you are already logged in. ([#4759](https://github.com/expo/eas-cli/pull/4759) by [@wschurman](https://github.com/wschurman))
+- [build-tools] Identify the build or application archive when a download fails, and explain when the archive is no longer available. ([#4703](https://github.com/expo/eas-cli/pull/4703) by [@gwdp](https://github.com/gwdp))
+- [build-tools] Run apsd setup in the background without delaying iOS app launch or preview readiness. ([#4706](https://github.com/expo/eas-cli/pull/4706) by [@gwdp](https://github.com/gwdp))
+- [eas-cli] Fix simulator control action help routing and show help when a flag is incomplete. ([#4681](https://github.com/expo/eas-cli/pull/4681) by [@gwdp](https://github.com/gwdp))
+- [eas-cli] Require explicit `host:` simulator-host upload paths and report missing local files. ([#4683](https://github.com/expo/eas-cli/pull/4683) by [@gwdp](https://github.com/gwdp))
+
+  Missing local absolute paths now require the `host:` prefix. Actions that require upload IDs accept local files and reject host paths with an explanation.
+
+- [build-tools] Handle a device session stopped during startup as normal cleanup instead of reporting a startup error. ([#4716](https://github.com/expo/eas-cli/pull/4716) by [@gwdp](https://github.com/gwdp))
+- [build-tools] Support idle timeouts for iOS web-preview-only sessions, resetting the timer when preview input arrives. ([#4731](https://github.com/expo/eas-cli/pull/4731) by [@gwdp](https://github.com/gwdp))
+
+### 🧹 Chores
+
+- [eas-cli] Run the GraphQL schema and generated code check on pull requests to any base branch, including stacked pull requests. ([#4763](https://github.com/expo/eas-cli/pull/4763) by [@wschurman](https://github.com/wschurman))
+
+## [26.0.0](https://github.com/expo/eas-cli/releases/tag/v26.0.0) - 2026-10-26
+
+### 🛠 Breaking changes
+
+- [eas-build-job][build-tools] Remove legacy artifact type exports and route workflow uploads through workflow storage without file-type categories. Preserve workflow uploads and Maestro reports. ([#4719](https://github.com/expo/eas-cli/pull/4719) by [@sjchmiela](https://github.com/sjchmiela))
+
+### 🎉 New features
+
+- [eas-build-job][build-tools] Export `validateAndroidLaunchOptions` and `quoteAndroidShellCommand` from `@expo/eas-build-job`, so Android launch arguments can be checked for NUL characters and length before a simulator session starts, and check them before the emulator boots in agent-device sessions. ([#4696](https://github.com/expo/eas-cli/pull/4696) by [@brentvatne](https://github.com/brentvatne))
+- [eas-json] Add `permissions.account.role` to build profiles to request a role for the build's `EXPO_TOKEN`. ([#4732](https://github.com/expo/eas-cli/pull/4732) by [@wschurman](https://github.com/wschurman))
+- [build-tools] Stop sandboxes after an optional maximum duration measured from readiness. ([#4702](https://github.com/expo/eas-cli/pull/4702) by [@sjchmiela](https://github.com/sjchmiela))
+- [build-tools] Unify signed URL uploading to a single implementation and use it everywhere. ([#4712](https://github.com/expo/eas-cli/pull/4712) by [@AHGIJMKLKKZNPJKQR](https://github.com/AHGIJMKLKKZNPJKQR))
+
+### 🐛 Bug fixes
+
+- [eas-cli] Regenerate graphql code. ([#4692](https://github.com/expo/eas-cli/pull/4692) by [@wschurman](https://github.com/wschurman))
+- [build-tools] Default Android emulators to 4 GiB of RAM to reduce ADB disconnects during large transfers. Retain the 2 GiB default for API 34 and below outside interactive device sessions, and preserve explicit emulator configuration overrides. ([#4727](https://github.com/expo/eas-cli/pull/4727) by [@sjchmiela](https://github.com/sjchmiela))
+- [build-tools] Retry transient failures when reporting that a device run session has started. ([#4680](https://github.com/expo/eas-cli/pull/4680) by [@gwdp](https://github.com/gwdp))
+- [build-tools] Retry the build lookup and the archive download of `eas/download_build` on transient failures, and name the failure cause in the build log. ([#4690](https://github.com/expo/eas-cli/pull/4690) by [@hSATAC](https://github.com/hSATAC))
+- [eas-cli] Read the app config fewer times in `eas build` and other project commands. An iOS build now runs `expo config` 2 times instead of 6. ([`78ba760`](https://github.com/expo/eas-cli/commit/78ba76001b67c9971236af1a1d02e46c2f82d24a) by [@vonovak](https://github.com/vonovak))

+- [build-tools] Add `launch_app_identifier`, `launch_args`, and `open_url` inputs to the serve-sim, agent-device, argent, and Appium remote sessions, so serve-sim launches an installed app before the stream starts. The inputs are iOS only, and Android sessions keep using `eas/launch_application`. ([#4324](https://github.com/expo/eas-cli/pull/4324) by [@gwdp](https://github.com/gwdp))
+- [build-tools] Stream iOS Simulator previews at 1600px and 10 Mbps. ([#4439](https://github.com/expo/eas-cli/pull/4439) by [@gwdp](https://github.com/gwdp))

+- [eas-cli] List `eas simulator` only once in `eas --help`. The `sim` shorthand is now a hidden alias, so it still runs but no longer duplicates the entry. ([#4457](https://github.com/expo/eas-cli/pull/4457) by [@krystofwoldrich](https://github.com/krystofwoldrich))
+- [build-tools] Start the Argent tool-server with `ARGENT_EMULATOR_NO_WINDOW=1`, so Argent can boot the Android emulator again after it stops. Without it, the windowed emulator fails on the Linux image because `libpulse.so.0` is missing. ([#4465](https://github.com/expo/eas-cli/pull/4465) by [@gwdp](https://github.com/gwdp))

+- [eas-cli] `eas simulator:start` and `eas simulator:get` now report the expo.dev preview page instead of the raw tunnel URL, in both the printed instructions and `--json`. ([#4352](https://github.com/expo/eas-cli/pull/4352) by [@gwdp](https://github.com/gwdp))
+
+### 🐛 Bug fixes
+
+- [eas-cli] Skip the managed-workflow Expo SDK and Metro config checks for builds that use a custom build config, since those builds run their own steps instead of the standard managed pipeline. ([#4424](https://github.com/expo/eas-cli/pull/4424) by [@douglowder](https://github.com/douglowder))
+- [build-tools] Honor `EAS_OVERRIDE_PACKAGE_MANAGER` and `EAS_FALLBACK_PACKAGE_MANAGER` when installing and launching simulator packages (serve-sim, device-hub, Argent, agent-device, Appium) so they can use bun instead of stalling on npm audit.

([#4370](https://github.com/expo/eas-cli/pull/4370) by [@hSATAC](https://github.com/hSATAC))
+
+### 🐛 Bug fixes
+
+- [eas-cli] Reject `--end` without `--start` in the `observe:*`, `update:insights`, `channel:insights`, and `update:view --insights` commands instead of silently falling back to the default time range. ([#4367](https://github.com/expo/eas-cli/pull/4367) by [@hSATAC](https://github.com/hSATAC))
+- [eas-cli] Reject a time range that does not run forwards in the `observe:*`, `update:insights`, `channel:insights`, `update:view --insights`, and `workflow:insights` commands instead of sending it to the server. ([#4367](https://github.com/expo/eas-cli/pull/4367) by [@hSATAC](https://github.com/hSATAC))

+- [eas-cli][build-tools] Forward `--egress-allow localhost:<port>` and `127.0.0.1:<port>` entries from the simulator host's loopback interface to this machine (like `adb reverse`), so dev server URLs that use `127.0.0.1` work through local egress. ([#4369](https://github.com/expo/eas-cli/pull/4369) by [@brentvatne](https://github.com/brentvatne))
+- [build-tools] Add the `eas/start_local_egress` step for iOS simulator sessions with local egress: the device host's system proxy points at a reverse tunnel to the EAS CLI machine, so HTTP(S) requests that honor it exit from that machine and third parties see its IP. ([#4364](https://github.com/expo/eas-cli/pull/4364) by [@brentvatne](https://github.com/brentvatne))
+- [eas-cli] Add `--egress local` to `eas simulator:start` and the `eas simulator:egress` command, which run the local egress client for the session. ([#4364](https://github.com/expo/eas-cli/pull/4364) by [@brentvatne](https://github.com/brentvatne))

 # Releasing EAS CLI
 
-1. Invoke the GitHub workflow ["Manually trigger a release"](https://github.com/expo/eas-cli/actions/workflows/trigger-release.yml). The next version is chosen automatically based on the changelog entries. If you want to use different version, pass the version string as an input to the workflow, in semver format, e.g. "1.2.3"
-2. That's it! GitHub Actions is going to take care of the rest. Watch the #eas-cli Slack channel for a successful release notification.
+1. Invoke the GitHub workflow ["Manually trigger a release"](https://github.com/expo/eas-cli/actions/workflows/trigger-release.yml). Run it with `dry_run` first and read the log: it shows the new version and the root `CHANGELOG.md` section.
+2. Run it again with `dry_run` unchecked. The workflow consumes the changesets in `.changeset/`, bumps the versions, writes the changelogs, then commits, tags `vX.Y.Z`, and pushes to `main`.
+3. That's it! GitHub Actions is going to take care of the rest. Watch the #eas-cli Slack channel for a successful release notification.
+
+The release also sets the `STAGING` and `PRODUCTION` versions in `cli-versions.json`. See [EAS Build CLI versions](#eas-build-cli-versions).
+
+## EAS Build CLI versions
+
+`cli-versions.json` at the repository root sets which `eas-cli` version EAS Build installs. It has two fields:
+
+- `STAGING`: the version used on the staging build servers.
+- `PRODUCTION`: the version used on the production build servers.
+
+This file replaces the old `latest-eas-build` and `latest-eas-build-staging` npm dist-tags. The build servers read the file from the `main` branch.
+
+A release updates `STAGING` and `PRODUCTION` to the new version automatically. To set a different version to production (to fix a regression, for example), invoke the GitHub workflow ["Promote eas-cli to production"](https://github.com/expo/eas-cli/actions/workflows/promote-eas-cli-production.yml). Pass the version to promote as an input. If you leave the input empty, the workflow uses the current `STAGING` version. The workflow checks that the version is published on npm before it updates `PRODUCTION`.
 
 ## Choosing the next version
 
-As stated above, the next EAS CLI version is chosen automatically based on the existing changelog entries under the unreleased section in **CHANGELOG.md**.
+The changesets in `.changeset/` choose the next version. All packages share one version (a changesets `fixed` group), and the highest bump in all changesets wins:
 
-The algorithm works as follows:
-
-- If there are any entries in the "🛠 Breaking changes" section, bump the MAJOR version.
-- Otherwise, if there are any entries in the "🎉 New features", bump the MINOR version.
+- If any changeset has a `major` bump, bump the MAJOR version.
+- Otherwise, if any changeset has a `minor` bump, bump the MINOR version.
 - Otherwise, bump the PATCH version.
+
+A release fails if there are no changesets, or if all of them are `none` or empty. To force a bump, merge a changeset with that bump type. See [`.changeset/README.md`](./.changeset/README.md) for how to write a changeset.
+
+## What a release writes
+
+`yarn release` (`scripts/src/versionPackages.ts`) does these steps:
+
+1. Reads the changesets and computes the new version.
+2. Runs `changeset version`. This bumps every `package.json`, writes each package's `CHANGELOG.md`, and deletes the changesets.
+3. Sets the version in `lerna.json`, updates `yarn.lock`, and regenerates `packages/eas-cli/README.md`.
+4. Adds the new section to the root `CHANGELOG.md`. The GitHub release and the Slack message use this section.
+5. Commits `vX.Y.Z`, tags it, and pushes. A dry run stops before this step.
+
+The tag push starts the [release workflow](./.github/workflows/release.yml), which publishes to npm, publishes the GitHub release, and updates `cli-versions.json`.
+
+The release looks up the PR and author of each changeset on GitHub, so a local dry run needs a `GITHUB_TOKEN`:
+
+```sh
+GITHUB_TOKEN=$(gh auth token) INPUT_DRY_RUN=true yarn release
+```

+# @expo/build-tools
+
+## 27.4.1
+
+### Patch Changes
+
+- Wait for a starting warm Simulator launcher before claiming its session, instead of falling back to a cold start. ([#4810](https://github.com/expo/eas-cli/pull/4810) by [@gwdp](https://github.com/gwdp))
+
+## 27.4.0
+
+### Minor Changes
+
+- Add `eas/start_warm_appium_remote_session`, which runs the Appium session on the warm Simulator, or starts cold. An `appium` claim stops the unused tools first, so WDA does not share the Simulator with the agent-device runner. ([#4735](https://github.com/expo/eas-cli/pull/4735) by [@gwdp](https://github.com/gwdp))
+- Add warm iOS session steps (`eas/start_warm_serve_sim_remote_session`, `eas/start_warm_agent_device_session`, `eas/start_warm_argent_remote_session`). They run the existing session on the warm Simulator, or start cold. `eas/start_agent_device_session` also accepts `install_app_path` and `launch_app_identifier`. ([#4723](https://github.com/expo/eas-cli/pull/4723) by [@gwdp](https://github.com/gwdp))
+- Update the app version and build number from the final application archive, so the build shows the values the native build resolved. ([#3499](https://github.com/expo/eas-cli/pull/3499) by [@kadikraman](https://github.com/kadikraman))
+
+### Patch Changes
+
+- Upload the final agent-device session artifacts before stopping the daemon, including sessions that reuse a warm Simulator. ([#4750](https://github.com/expo/eas-cli/pull/4750) by [@gwdp](https://github.com/gwdp))
+- Add internal helpers that claim the warm Simulator through the launcher and adopt it on the warm serve-sim. Skip the Expo Go install when the warm Simulator already has the same Expo Go version. ([#4724](https://github.com/expo/eas-cli/pull/4724) by [@gwdp](https://github.com/gwdp))
+- Recover warm Simulator recordings when their MP4 exists before the shutdown manifest is ready. ([#4789](https://github.com/expo/eas-cli/pull/4789) by [@gwdp](https://github.com/gwdp))
+
+## 27.3.0
+
+### Patch Changes
+
+- Stop warmup in the background for jobs that do not use the warm Simulator, so job setup does not wait for it. Before build-tools boots or clones a Simulator, it waits until the launcher's state file records that cleanup finished, and fails if cleanup does not finish in time. ([#4721](https://github.com/expo/eas-cli/pull/4721) by [@gwdp](https://github.com/gwdp))
+- Recover unhealthy device-session tunnels without changing their URLs and block further traffic when shutdown starts, even if ngrok cleanup times out. ([#4526](https://github.com/expo/eas-cli/pull/4526) by [@gwdp](https://github.com/gwdp))
+- Stop sending the SSH host when registering an SSH session. ([#4784](https://github.com/expo/eas-cli/pull/4784) by [@AHGIJMKLKKZNPJKQR](https://github.com/AHGIJMKLKKZNPJKQR))
+
+## 27.2.0
+
+### Minor Changes
+
+- Use single-device previews when the session already has a valid device ID. ([#4733](https://github.com/expo/eas-cli/pull/4733) by [@gwdp](https://github.com/gwdp))
+
+### Patch Changes
+
+- Explain missing background task identifiers reported by App Store Connect. ([#3465](https://github.com/expo/eas-cli/pull/3465) by [@sjchmiela](https://github.com/sjchmiela))
+- Explain App Store Connect NOT_AUTHORIZED responses in the shared API client. ([#3462](https://github.com/expo/eas-cli/pull/3462) by [@sjchmiela](https://github.com/sjchmiela))
+- Explain App Store Connect UNEXPECTED_ERROR responses in the shared API client. ([#3467](https://github.com/expo/eas-cli/pull/3467) by [@sjchmiela](https://github.com/sjchmiela))
+- Explain missing app icons reported by App Store Connect, including codes 90022 and 90023, while preserving Apple’s validation details. ([#3466](https://github.com/expo/eas-cli/pull/3466) by [@sjchmiela](https://github.com/sjchmiela))
+- List failed Google Play commit attempts in order, including network failures, when the outcome is uncertain. ([#4660](https://github.com/expo/eas-cli/pull/4660) by [@sjchmiela](https://github.com/sjchmiela))
+- Fix a five-minute cleanup delay when a device session is canceled during startup and its screen recorder fails before connecting. ([#4761](https://github.com/expo/eas-cli/pull/4761) by [@gwdp](https://github.com/gwdp))
+- Handle TURN requests for a stopped device session without reporting a warning. ([#4762](https://github.com/expo/eas-cli/pull/4762) by [@gwdp](https://github.com/gwdp))
+- Preserve indented and incomplete Xcode compiler errors in formatted build logs, including the final diagnostic when logging stops. ([#4365](https://github.com/expo/eas-cli/pull/4365) by [@sjchmiela](https://github.com/sjchmiela))
+
+## 27.1.0
+
+### Patch Changes
+
+- Explain App Store Connect error 90189 as a duplicate build number. ([#3461](https://github.com/expo/eas-cli/pull/3461) by [@sjchmiela](https://github.com/sjchmiela))
+- Put the `NPM_TOKEN` registry credential in the builder's npm user config on EAS Build (`~/.npmrc`, or the file `NPM_CONFIG_USERCONFIG` names), where pnpm 10.34.2+ and 11.5.3+ still expand `${NPM_TOKEN}` (they ignore it in a project-level `.npmrc`). Explain what to change when the project's pnpm version needs a newer Node.js than the build runs, including when eas.json sets `node` or `pnpm`. ([#4729](https://github.com/expo/eas-cli/pull/4729) by [@hSATAC](https://github.com/hSATAC))
+- Install `@expo/repack-app` for the `eas/repack` step with npm in a sandbox that sees only `PATH` and its own `HOME`, so the build machine's npm and Yarn configuration cannot break the install, fetch it through the EAS npm cache when the job uses one, and show the installer output in the build log. The step no longer looks the version up separately before installing. When the npm cache fails, the install retries against the public registry like the project install does; the `eas/run_agent` agent CLI install shares the same helper and gains the same retry. ([#4728](https://github.com/expo/eas-cli/pull/4728) by [@hSATAC](https://github.com/hSATAC))
+
+## 27.0.0
+
+### Patch Changes
+
+- Keep the launched app open when an Appium iOS session starts. ([#4699](https://github.com/expo/eas-cli/pull/4699) by [@gwdp](https://github.com/gwdp))
+- Run Appium through the prepared Full Disk Access helper when available on macOS. ([#4622](https://github.com/expo/eas-cli/pull/4622) by [@gwdp](https://github.com/gwdp))
+- Identify the build or application archive when a download fails, and explain when the archive is no longer available. ([#4703](https://github.com/expo/eas-cli/pull/4703) by [@gwdp](https://github.com/gwdp))
+- Run apsd setup in the background without delaying iOS app launch or preview readiness. ([#4706](https://github.com/expo/eas-cli/pull/4706) by [@gwdp](https://github.com/gwdp))
+- Handle a device session stopped during startup as normal cleanup instead of reporting a startup error. ([#4716](https://github.com/expo/eas-cli/pull/4716) by [@gwdp](https://github.com/gwdp))
+- Support idle timeouts for iOS web-preview-only sessions, resetting the timer when preview input arrives. ([#4731](https://github.com/expo/eas-cli/pull/4731) by [@gwdp](https://github.com/gwdp))
+
+## 26.0.0
+
+### Major Changes
+
+- Remove legacy artifact type exports and route workflow uploads through workflow storage without file-type categories. Preserve workflow uploads and Maestro reports. ([#4719](https://github.com/expo/eas-cli/pull/4719) by [@sjchmiela](https://github.com/sjchmiela))
+
+### Minor Changes
+
+- Stop sandboxes after an optional maximum duration measured from readiness. ([#4702](https://github.com/expo/eas-cli/pull/4702) by [@sjchmiela](https://github.com/sjchmiela))
+- Unify signed URL uploading to a single implementation and use it everywhere. ([#4712](https://github.com/expo/eas-cli/pull/4712) by [@AHGIJMKLKKZNPJKQR](https://github.com/AHGIJMKLKKZNPJKQR))
+
+### Patch Changes
+
+- Default Android emulators to 4 GiB of RAM to reduce ADB disconnects during large transfers. Retain the 2 GiB default for API 34 and below outside interactive device sessions, and preserve explicit emulator configuration overrides. ([#4727](https://github.com/expo/eas-cli/pull/4727) by [@sjchmiela](https://github.com/sjchmiela))
+- Export `validateAndroidLaunchOptions` and `quoteAndroidShellCommand` from `@expo/eas-build-job`, so Android launch arguments can be checked for NUL characters and length before a simulator session starts, and check them before the emulator boots in agent-device sessions. ([#4696](https://github.com/expo/eas-cli/pull/4696) by [@brentvatne](https://github.com/brentvatne))
+- Retry transient failures when reporting that a device run session has started. ([#4680](https://github.com/expo/eas-cli/pull/4680) by [@gwdp](https://github.com/gwdp))
+- Retry the build lookup and the archive download of `eas/download_build` on transient failures, and name the failure cause in the build log. ([#4690](https://github.com/expo/eas-cli/pull/4690) by [@hSATAC](https://github.com/hSATAC))
+- Stop printing workflow hook parsing messages in build logs: native builds showed them under an "Unknown build phase" group, and custom builds warned about unknown hook keys and hooks on steps that never run. ([#4717](https://github.com/expo/eas-cli/pull/4717) by [@hSATAC](https://github.com/hSATAC))
+
+## 25.3.0
+
+### Minor Changes
+
+- Let serve-sim boot, install and launch Argent iOS sessions. ([#4602](https://github.com/expo/eas-cli/pull/4602) by [@gwdp](https://github.com/gwdp))
+- Let serve-sim boot, install and launch Appium iOS sessions. ([#4603](https://github.com/expo/eas-cli/pull/4603) by [@gwdp](https://github.com/gwdp))
+- Upload the screen recording session manifest as a JSON artifact alongside each video. ([#4689](https://github.com/expo/eas-cli/pull/4689) by [@gwdp](https://github.com/gwdp))
+
+### Patch Changes
+
+- Quote Android launch arguments and URLs for the device shell in simulator sessions, so values with spaces or shell characters reach `am start` as one argument; pass raw values and remove any shell quoting added as a workaround. ([#4695](https://github.com/expo/eas-cli/pull/4695) by [@brentvatne](https://github.com/brentvatne))
+- Wait up to five minutes for Google Play to finish processing an uploaded bundle before giving up on the edit commit. ([#4700](https://github.com/expo/eas-cli/pull/4700) by [@hSATAC](https://github.com/hSATAC))
+- Reset the device run session idle timer on iOS Simulator preview input. ([#4691](https://github.com/expo/eas-cli/pull/4691) by [@gwdp](https://github.com/gwdp))
+- Forward captured Simulator traffic through the local egress proxy. ([#4598](https://github.com/expo/eas-cli/pull/4598) by [@gwdp](https://github.com/gwdp))
+
+## 25.2.0

+
+## 25.1.1
+
+### Patch Changes
+
+- Call www only through the device run session worker API in device run session jobs, and remove their GraphQL fallbacks. ([#4638](https://github.com/expo/eas-cli/pull/4638) by [@szdziedzic](https://github.com/szdziedzic))
+
+## 25.1.0
+
+### Minor Changes
+
+- Pass the `cors_origins` session input to serve-sim and expo-device-hub as `--cors-origin` origins, so a third party page can call the preview host API, for example with `@expo/hub-client`. ([#4657](https://github.com/expo/eas-cli/pull/4657) by [@krystofwoldrich](https://github.com/krystofwoldrich))
+- Pass the `frame_ancestors` session input to serve-sim and expo-device-hub as `--frame-ancestor` origins, so a third party can embed the preview host. ([#4655](https://github.com/expo/eas-cli/pull/4655) by [@krystofwoldrich](https://github.com/krystofwoldrich))
+
+### Patch Changes
+
+- Allocate 4 GiB of guest RAM to Android emulators in EAS Simulator sessions. ([#4640](https://github.com/expo/eas-cli/pull/4640) by [@gwdp](https://github.com/gwdp))
+- Retry transient Google Play API failures with exponential backoff while keeping uncertain commit results explicit. ([#4629](https://github.com/expo/eas-cli/pull/4629) by [@sjchmiela](https://github.com/sjchmiela))

+- Report Google Play error responses to Sentry so unexplained submission failures can be classified. ([#4652](https://github.com/expo/eas-cli/pull/4652) by [@sjchmiela](https://github.com/sjchmiela))
+
+## 25.0.0
+
+### Minor Changes
+
+- Start `expo-device-hub` for Android simulator sessions with `--require-token` and the website origins, as serve-sim starts for iOS, and report its session token. ([#4578](https://github.com/expo/eas-cli/pull/4578) by [@krystofwoldrich](https://github.com/krystofwoldrich))

+# egress-guard
+
+A small dylib injected into every process the iOS Simulator launches during a
+`--egress local` session. It interposes the socket calls that open outbound
+traffic (`connect`, `connectx`, `sendto`, `sendmsg`, and the `$NOCANCEL`
+variants of the last three that libsystem exports alongside them) and refuses
+any destination that is not loopback. A sockaddr whose family was left
+`AF_UNSPEC` is classified as the family its length implies, which is how the
+kernel treats it for TCP `connect` and IPv4 sends; on a datagram socket
+`connect(AF_UNSPEC)` is left to the kernel, which dissolves the association. The system proxy and the `--egress-allow`
+forwards live on loopback, so everything that honors the proxy keeps working
+and everything that bypasses it fails with `ECONNREFUSED` in the process that
+tried, with the calling frameworks recorded.
+
+Why interposing: simulator processes share the worker's uid, so a packet
+filter cannot tell them apart from the worker's own traffic. dyld interposing
+from an inserted library reaches calls made inside Apple's own frameworks
+(CFNetwork, Network.framework), and `launchctl setenv DYLD_INSERT_LIBRARIES`
+inside the simulator makes launchd hand the library to every process it
+spawns. The simulator does not enforce library validation, which is what makes
+this possible there and nowhere else.
+
+Configuration comes from the environment the simulator's launchd provides:
+
+- `EAS_EGRESS_GUARD_LOG`: file the guard appends events to (host path).
+- `EAS_EGRESS_GUARD_MODE`: `block` (default, and what any unknown value means)
+  or `log` (observe only).
+
+Each event is one tab-separated line:
+
+```
+eas-egress-guard\t<process>\t<pid>\t<function>\t<blocked|logged>\t<peer>\t<caller>,<caller>...
+```
+
+A process lists each `(function, peer)` once, up to 128 of them. When that
+table fills it writes one more line with function `overflow` and the limit as
+the peer; further distinct destinations are still refused but not listed.
+
+Layout:
+
+- `policy.c` / `policy.h`: classification, mode, formatting, per-process
+  dedupe. Pure C, host-testable.
+- `guard.c`: the interposers and the constructor that reads the environment.
+- `check.c`: `egress-guard-check`, run inside the simulator right after the
+  guard is installed. Exits non-zero unless the library is loaded in a fresh
+  process and behaves as the mode says on `connect`, `connect$NOCANCEL` and a
+  `connect` with an `AF_UNSPEC` sockaddr; the worker fails the session on that.
+- `tests/policy_test.c`: host unit tests, `tests/run-policy-tests.sh`.
+- `tests/guard_test.c`, `tests/guard_insert_test.c`: host tests of the
+  interposers themselves, `tests/run-guard-tests.sh`. The first compiles
+  `guard.c` in and forces the lock schedules (a signal handler making a socket
+  call inside the critical section, a fork while another thread holds the lock,
+  contention); the second inserts the built library like the simulator does and
+  checks descriptor reuse, the `$NOCANCEL` symbols, `AF_UNSPEC` shapes and the
+  UDP disconnect. Nothing in them opens a socket to a non-loopback address.
+- `tests/nettest.swift`: probe binary the simulator end-to-end test runs inside
+  a device; exercises URLSession, Network.framework, BSD TCP and UDP, DNS.
+- `build.sh`: universal simulator dylib into `packages/build-tools/bin/`.
+
+Installation order matters. `simctl` forwards every `SIMCTL_CHILD_`-prefixed
+variable of its own environment to the process it starts, and for `simctl
+boot` that process is the simulator's launchd, so the worker boots with the
+guard and proxy variables in that form and every process of the boot inherits
+them (measured: 176 of 176). `launchctl setenv` after boot is kept for a
+device that was already booted, but by then the boot's own processes have
+started without it. It also cannot change a variable the boot already carried:
+a device booted with one guard configuration keeps it until it is shut down,
+which is why the worker boots devices itself and every configuration in the
+end-to-end test gets its own boot. The self-check runs once boot completes and is followed
+by a coverage report from `lsof`, listing any process without the library. Both the dylib and the check binary are built by
+`packages/worker/package.sh` for the iOS worker tarball and by the
+`test-egress-guard` EAS workflow, not committed.
+
+For serve-sim-owned iOS session startup, build-tools passes the guard through
+`SERVE_SIM_ADDITIONAL_DYLIBS` and its configuration and proxy variables through
+inherited `SIMCTL_CHILD_` variables. It shuts down an already booted selected
+device so every process inherits the guard. Serve-sim boots that device while
+build-tools prepares the app. After serve-sim's control endpoint is available,
+build-tools runs the packaged guard self-check before requesting installation
+and launch through the authenticated host API. Preview readiness and application
+startup both complete before reporting the remote session live. Build-tools keeps
+the event relay and egress cleanup without rewriting launchd's dylib list after
+serve-sim adds its capability loader.
+
+Failure semantics: a missing library, a failed `launchctl setenv`, or a failed
+self-check fails the session, since a `--egress local` session without the
+guard would silently leak. Only an unwritable event log is a warning, because
+refusals still happen and only the reporting is lost. Recording is best-effort
+in the process too: the event log is opened per event rather than held open
+(a process that closes descriptors it does not own, as `launchd_sim` does,
+would otherwise make the guard write into whatever reused the number), and a
+dedupe slot that cannot be taken within a bounded number of attempts (a signal
+handler re-entering the guard, a fork child inheriting a held lock) skips the
+event rather than blocking or aborting the process.

-# RecordSim
-
-Small Swift library for non-exclusive iOS Simulator screen recording.
-
-It implements one recording path:
-
-1. Listen to SimRenderServer framebuffer callbacks.
-2. Copy the live `IOSurface` immediately into an owned `CVPixelBuffer`.
-3. Feed one continuous `AVAssetWriter`.
-4. Emit Apple HLS/CMAF-style fragmented MP4 segments.
-
-The output is suitable for uploading while recording. `session.json` contains
-the ordered segment metadata needed to build a playlist later.
-
-## Output
-
-```text
-session/
-  init.mp4
-  session.json
-  segments/
-    segment-000000.m4s
-    segment-000001.m4s
-```
-
-`init.mp4` is the fMP4 initialization segment. Individual `.m4s` files are not
-standalone MP4 files. `session.json` stores the wall-clock timestamp for the
-first video frame plus the metadata needed to build a playlist: HLS version,
-target duration, media sequence, `initSegment`, and the ordered `segments` array
-with file path and duration for each media segment.
-
-## CLI
-
-```bash
-swift run record-sim \
-  --udid <BOOTED_SIMULATOR_UDID> \
-  --output /tmp/sim-recording \
-  --segment-duration 120 \
-  --fps 30 \
-  --bitrate 30000000 \
-  --codec h264
-```
-
-For sparse 2h sessions, `--segment-duration 120` is a reasonable default: about
-60 media objects plus the init segment. The recorder appends a single duplicate
-hold frame near each segment boundary when the simulator is idle, so long idle
-periods still produce uploadable segments without encoding idle frames at 60fps.
-Use `--segment-duration 0` to write one continuous `recording.mp4` instead of
-`init.mp4` plus media segments.
-
-Frame timestamps use monotonic host time, not wall-clock time. The recorder also
-probes the framebuffer seed once per second; if the surface changes without
-callbacks for 5 seconds, it captures that frame and rewires the private callback
-registration.
-
-## Library
-
-```swift
-let recorder = SimulatorRecorder(
-  configuration: SimulatorRecordingConfiguration(
-    deviceUDID: udid,
-    outputDirectory: sessionDirectory,
-    segmentDuration: 120
-  )
-)
-
-recorder.onSegment = { segment in
-  // Enqueue upload of segment.url.
-}
-
-try recorder.start()
-try recorder.waitUntilFirstFrame()
-// ...
-let manifest = try recorder.stop()
-```
-
-`session.json` contains the precise wall-clock time for video PTS zero. In
-segmented mode it also contains the init segment and ordered media segment
-file/duration entries; in single-file mode it points at `recording.mp4`.
