## Purpose

This is the durable release-readiness checklist for the targeted upstream version (`agent-browser` version in `CAPABILITY_BASELINE.targetVersion`). It maps the canonical capability baseline in [`scripts/agent-browser-capability-baseline.mjs`](../scripts/agent-browser-capability-baseline.mjs) to documentation, runtime handling, tests, and validation evidence. Update it whenever the baseline version or inventory changes.

## Maintainer refresh checklist

When upstream ships a new `agent-browser` or the inventory changes:

1. Edit [`scripts/agent-browser-capability-baseline.mjs`](../scripts/agent-browser-capability-baseline.mjs) (`targetVersion`, `helpCommands`, `inventorySections`) using real `--help` output from the binary you intend to target (the file never shells out to `agent-browser`).
2. Align human prose and required tokens in [`COMMAND_REFERENCE.md`](COMMAND_REFERENCE.md) outside the generated HTML-comment blocks.
3. Regenerate bounded blocks with `npm run docs -- command-reference write`, then run `npm run docs` (or `npm run docs -- command-reference check`).
4. Update the **Baseline checklist by inventory section** table below so each `CAPABILITY_BASELINE.inventorySections[].id` row still points at the right docs, code, tests, and status notes.
5. Re-run the gates in **Verification evidence** on a machine that matches release expectations (`pi`, `tmux`, model config for lifecycle) and replace the dated status cells with fresh outcomes.

## Audit result

- Target upstream: `agent-browser 0.33.2` (must match `CAPABILITY_BASELINE.targetVersion` in [`scripts/agent-browser-capability-baseline.mjs`](../scripts/agent-browser-capability-baseline.mjs)).
- Source of truth: `CAPABILITY_BASELINE.inventorySections` in the same file (stable `id` keys: `skills`, `core-commands`, `state-tabs-frames-dialogs`, `network-storage-artifacts-diagnostics`, `batch-auth-setup-ai`, `options-and-env`).
- Status: source and wrapper adaptation target the 2026-08-02 0.33.2 audit. Keeps 0.33.0 a11y/HAR/`find` coverage, documents 0.33.1 idle-timeout/tab-recovery and 0.33.2 stream quality/size env vars, and enables Git-checkout-generation-stable `AGENT_BROWSER_RESTORE` for extension-managed `piab-*` sessions so SSO cookies survive browser relaunches. Prior helper idle-timeout, post-`tab close` target refresh, and document-direction scroll behavior remain.
- High-priority support gaps: 2026-05-26 audit found sessionless local commands and command-scoped value flags needed sharper wrapper handling; runtime/tests/docs now cover those paths. The 0.28.0 rebaseline added local `mcp` and `plugin` surfaces plus plugin-backed credential login; wrapper docs/tests mark `mcp` and known `plugin` commands sessionless, with no compatibility shim for older upstream releases. The 0.29.1 rebaseline added upstream `@agent-browser/sandbox` helper-package guidance and stricter `install --with-deps` failure semantics; no new wrapper runtime mode or bundled dependency was required. The 0.30.1 rebaseline fixed upstream `wait --url` glob matching, so constrained `job.assertUrl` delegates glob and exact patterns directly to `wait --url`. The 0.31.0 rebaseline adds restore workflow and namespace/session lifecycle surfaces (`--restore`, restore checks, `--namespace`, `session id`, and `session info`) without adding a wrapper compatibility layer. The 0.31.1 rebaseline fixes upstream React renderer selection for `react tree`, `react inspect`, and `react suspense`; no wrapper runtime change was required. The 0.31.2 rebaseline adds the local-launch-only `--webgpu` preset and `doctor --webgpu`, plus periodic restore-state autosaves controlled by `AGENT_BROWSER_AUTOSAVE_INTERVAL_MS`; the wrapper treats WebGPU as launch-scoped and, for wrapper-owned headed launches, defaults autosave off to avoid upstream 0.33.2's visible temporary storage-collector tabs while preserving save-on-close and explicit opt-in at daemon launch; changing a running daemon requires close plus a fresh launch. The 0.32.0 rebaseline hardens request/worker/popup/WebRTC containment behind `--allowed-domains`, fixes waits against already-complete documents, and adds a separate `@agent-browser/eve` package; the wrapper makes containment launch-scoped, retains its final-URL check as defense in depth, and adds no Eve-specific mode. The 0.32.1–0.32.2 rebaseline updates only eve compatibility/packaging, but the full current-surface audit also found the local reference had omitted upstream `read [url]` since 0.30.0; baseline/help sampling, content-first presentation, tab-target preservation, timeout budgeting, docs, and tests now cover it. The 0.32.3–0.32.4 rebaseline adds HAR response-body capture modes, the `derive-client` skill, fixed `find role` implicit-ARIA / accessible-name matching with locator-detail misses, and an advertised `find` action list of `click, fill, check, hover, text` only; the wrapper documents and classifies those surfaces without adding a new input mode. Remaining upstream-owned caveat: some help paths still mention `wait <selector> --state hidden` / `detached`, but runtime probes show those shapes still fail, so wrapper docs keep `wait --fn` disappearance predicates and top-level `uncheck` / `type` / `focus` passthrough instead of `find` for those actions. `wait --download <path>` still reports the requested path without guaranteed on-disk persistence ([#1300](https://github.com/vercel-labs/agent-browser/issues/1300)).
- Post-`v0.2.29` review state: commits `eb55320` through `86abbfb` add browser guidance/smoke coverage plus `RQ-0086` click-probe reduction, `RQ-0087` same-snapshot form fill batching, `RQ-0088` current-ref fallback on locator misses, `RQ-0089` direct-upstream click mutation investigation, and `RQ-0090` stop-boundary/artifact-path guidance. Verification gates below were rerun on 2026-05-18 after those tasks landed. Constrained `job` (`RQ-0064`), the lightweight `qa` preset (`RQ-0065`), the experimental `sourceLookup` helper (`RQ-0066`), the experimental `networkSourceLookup` helper (`RQ-0067`), optional Exa/Brave-backed `agent_browser_web_search` with Pi-scoped package config (`RQ-0121`), and agent recovery for search/profile configuration failures (`RQ-0122`) are implemented; see [`TOOL_CONTRACT.md`](TOOL_CONTRACT.md#job), [`TOOL_CONTRACT.md`](TOOL_CONTRACT.md#qa), [`TOOL_CONTRACT.md`](TOOL_CONTRACT.md#sourcelookup), [`TOOL_CONTRACT.md`](TOOL_CONTRACT.md#networksourcelookup), and [`TOOL_CONTRACT.md`](TOOL_CONTRACT.md#optional-companion-web-search). Reusable browser recipes (`RQ-0068`) are intentionally not adopted as a runtime surface; see [`ARCHITECTURE.md`](ARCHITECTURE.md#no-reusable-recipe-layer-yet).

## UX/reliability decisions from 2026-05-29 agent feedback

Closed feedback decisions map to their canonical contracts in [`docs/support-notes.md`](https://github.com/fitchmultz/pi-agent-browser-native/blob/main/docs/support-notes.md). Keep this active matrix limited to release-critical status and gates.

Current summary:

| Range | Status | Source of truth |
| --- | --- | --- |
| RQ-0110–RQ-0120 | Agent feedback triage resolved or documented; remaining unsupported areas are environment/upstream-owned. | [`docs/support-notes.md`](https://github.com/fitchmultz/pi-agent-browser-native/blob/main/docs/support-notes.md) |

| RQ-0131 | Upstream `agent-browser 0.31.0` rebaseline shipped; restore workflow and namespace/session lifecycle globals are parsed, documented, and carried through wrapper-managed probes/state. | [`docs/COMMAND_REFERENCE.md`](COMMAND_REFERENCE.md#upstream-0310-rebaseline) |
| RQ-0132 | Upstream `agent-browser 0.31.1` rebaseline shipped; React renderer selection is upstream-fixed for `react tree`, `react inspect`, and `react suspense`, with no wrapper CLI/schema changes. | [`docs/COMMAND_REFERENCE.md`](COMMAND_REFERENCE.md#upstream-0311-rebaseline) |
| RQ-0133 | Upstream `agent-browser 0.31.2` rebaseline adds WebGPU launch/doctor/MCP surfaces and periodic restore-state autosaves; wrapper launch parsing/policy and docs now cover both. | [`docs/COMMAND_REFERENCE.md`](COMMAND_REFERENCE.md#upstream-0312-rebaseline) |
| RQ-0134 | Upstream `agent-browser 0.32.0` rebaseline hardens domain containment, fixes completed-page waits, and adds a separate eve extension package; wrapper launch policy and docs cover the relevant behavior. | [`docs/COMMAND_REFERENCE.md`](COMMAND_REFERENCE.md#upstream-0320-rebaseline) |
| RQ-0135 | Upstream `agent-browser 0.32.2` rebaseline updates eve packaging only and closes the wrapper's prior missing `read [url]` inventory/presentation contract. | [`docs/COMMAND_REFERENCE.md`](COMMAND_REFERENCE.md#upstream-0322-rebaseline) |
| RQ-0136 | Wrapper regression fix keeps helper subprocess launch environments stable, refreshes active tab state after `tab close`, and makes ordinary document-direction scrolling deterministic before upstream fallback. | [`docs/ARCHITECTURE.md`](ARCHITECTURE.md), [`docs/TOOL_CONTRACT.md`](TOOL_CONTRACT.md#details) |
| RQ-0137 | Upstream `agent-browser 0.32.4` rebaseline adds HAR `--content` body modes, the `derive-client` skill, and fixed `find role` implicit-ARIA/name matching with locator-detail misses; wrapper classifier/argv/docs cover those surfaces. | [`docs/COMMAND_REFERENCE.md`](COMMAND_REFERENCE.md#upstream-0330-rebaseline) |
| RQ-0138 | Upstream `agent-browser 0.33.0` rebaseline adds `a11y` axe-core audits and discarded-tab revival on tab switch; wrapper documents/presents `a11y` and samples the new help surface. | [`docs/COMMAND_REFERENCE.md`](COMMAND_REFERENCE.md#upstream-0330-rebaseline) |
| RQ-0139 | Upstream `agent-browser 0.33.2` rebaseline documents daemon idle timeout, stream quality/size envs, and tab-recovery fields; wrapper enables Git-checkout-generation-stable managed-session restore for SSO stickiness with canonical namespace identity, replayable pinned managed/Electron probes, nested attachment isolation, check-to-spawn config pinning with native POSIX/Windows stale-root identity, fail-closed restore storage, JSON close-state capture, and lockless convergent ownership-proven snapshot retention plus immutable ticket-claim cross-process daemon-policy locking with mandatory per-winner daemon inspection, a pre-update v2 bridge, absolute POSIX process probes, PID/start-identity dead-claim/artifact recovery, final post-setup spawn revalidation, managed restore-capability redaction/access guards, same-process restore-disabled daemon provenance plus inactive-daemon null-policy restart, owned-policy Electron probes, abort-safe Electron launch, independent daemon-inspection timeout, case-insensitive reserved managed live-session names, all-failed Electron probe classification, fail-closed POSIX socket ancestry/entry validation, pinned-disabled file access (including raw Chrome args/config) plus protected local CLI/environment input/output paths, authoritative persisted unverified/failed page transitions and URL-first Electron handoff cleanup, and local state-file navigation, same-checkout-lineage generation expiry, malformed-output discard, a per-key 256-record churn bound, caller-owned explicit-session live URL gating before content access, process-local canonical per-session serialization through semantic snapshots and main execution, non-bail batch failure-path analysis that prevents prior-page content exposure, semantic live gating before snapshot resolution, Windows drive-relative protected-path detection, nested batch rejection, and upstream ASCII-space batch-tokenizer parity. | [`docs/COMMAND_REFERENCE.md`](COMMAND_REFERENCE.md#upstream-0332-rebaseline), [`docs/ARCHITECTURE.md`](ARCHITECTURE.md) |
| RQ-0140 | Successful CDP/auto-connect and Electron sessions preserve one attached browser across native-tool follow-ups and cleanup by omitting wrapper local-launch defaults, with environment support, branch replay, first-use content blocking, live URL gates against external drift, and close cleanup. | [`docs/ARCHITECTURE.md`](ARCHITECTURE.md), [`docs/TOOL_CONTRACT.md`](TOOL_CONTRACT.md), `test/agent-browser.extension-passthrough-validation.test.ts` |
| RQ-0141 | Headed managed sessions avoid upstream 0.33.2 visible autosave targets by default and retain that daemon environment across helpers, still-owned off-current follow-ups, failed-replacement ownership, Electron cleanup, and reload/resume; slow daemon-policy inspection uses a 35-second budget; headed mode is launch-scoped; the effective launch interval persists across resume and changes in either direction require close plus a fresh daemon; and bare, review-only, fenced-reference, conditional, directly negated, or reference attachment paths do not become close-blocking output requirements while explicit contiguous output path lists, per-clause availability, duplicate precedence, and Markdown destinations are handled conservatively and linearly. | [`docs/ARCHITECTURE.md`](ARCHITECTURE.md), [`docs/TOOL_CONTRACT.md`](TOOL_CONTRACT.md), `test/agent-browser.managed-session-daemon-policy.test.ts`, `test/agent-browser.process.test.ts`, `test/agent-browser.prompt-policy.test.ts` |

## Verification evidence

Re-run the gates below before each release; this table records what the closure audit exercised. The 0.33.2 release gates for package 0.3.0 were refreshed on 2026-08-06 against Pi 0.84.0. Local build/typecheck/tests/docs, real-upstream, packaged-Pi, startup-profile, and deterministic plus interactive packed dogfood paths passed. Ubuntu Crabbox passed both target suites; macOS was attempted but its SSH provider warmup failed, and native Windows was explicitly waived for this release.

| Gate | Evidence | Status |
| --- | --- | --- |
| Default local gate | `npm run verify` checks generated playbook drift, clean-builds generated `dist/`, runs `tsc --noEmit`, unit/fake tests, generated command-reference blocks, and live command-reference sampling. | **Current for 0.33.2 / Pi 0.84.0:** refreshed on 2026-08-06; build, typecheck, docs drift, live command-reference sampling, and focused Pi 0.84.0 SDK/doctor/package suites passed. |
| Pre-PR local gate | `npm run verify -- pre-pr` composes the default gate with package-content verification. Use before larger local handoffs or PR-ready claims when lifecycle/platform/live dogfood cost is not warranted. | **Current for 0.33.2 / package 0.3.0:** package-content verification and packed Pi smoke passed independently on 2026-08-06; the serial full-suite component was rerun separately because an earlier composed invocation exceeded the calling shell's one-hour limit. |
| Real upstream contract | `npm run verify -- real-upstream` runs the localhost fixture matrix against the real installed `agent-browser` matching the baseline. | **Current for 0.33.2:** pass on 2026-08-06 (2/2 real-upstream tests). |
| Packaged Pi smoke | `npm run verify -- package-pi` validates package contents, loads the packaged `agent_browser` tool without requiring optional Brave config, and executes fake-upstream `--version`. | **Current for package 0.3.0 / Pi 0.84.0:** pass on 2026-08-06; a separate 120-file tarball also loaded in interactive Pi from `npm:...@file:` for packed dogfood. |
| Startup profile | `npm run verify -- startup-profile --samples <n>` clean-builds generated `dist/`, records direct package entrypoint import/factory timing in fresh Node processes, and writes `.artifacts/startup-profile/latest.json`. It must not launch Pi, tmux, mise, npm, browsers, or `agent-browser`; full Pi TUI ready-prompt profiling is intentionally excluded after it proved too invasive for routine verification. Run this opt-in evidence when package layout, the compiled entrypoint, top-level imports, schema registration, or prompt/config startup logic changes. | **Current for compiled entrypoint:** pass on 2026-08-06 with five samples, all below the 250 ms budget. Full-Pi startup numbers from the unsafe tmux profiler are not accepted as ongoing release evidence. |
| Deterministic dogfood smoke | `npm run verify -- dogfood` (`scripts/verify-agent-browser-dogfood.ts`) drives the native wrapper against a loopback HTTP fixture through top-level `qa`, `semanticAction`, constrained `job`, screenshot artifact verification, and session close with the real `agent-browser` on `PATH`. | **Current for 0.33.2 / package 0.3.0 / Pi 0.84.0:** deterministic dogfood passed on 2026-08-06. Interactive packed-tarball dogfood passed fresh-session form fill/navigation, snapshots, React QA, verified screenshots, `sourceLookup` diagnostics, `electron.list`, deterministic loopback download verification (46 bytes), and browser cleanup. A public Heroku download endpoint timed out, but the same packed `download` path passed against the controlled fixture. |
| WebGPU and restore autosave | Live 0.31.2 feature probes validate the new upstream paths independently from ordinary browser dogfood. | **macOS:** `doctor --webgpu` passed Apple Metal render/readback and headless red-pixel screenshot checks; the official Hello Triangle sample exposed the Metal adapter and produced a verified non-black screenshot. **Ubuntu image:** `doctor --webgpu --headed --json` passed SwiftShader render/readback and red-pixel screenshot checks with the baked Vulkan/Mesa/Xvfb dependencies. **Restore autosave:** an idle headless page timer changed localStorage and the namespaced restore file contained the new value before close; test state was removed. Wrapper-owned headed launches default periodic autosave off to avoid upstream 0.33.2 visible temporary collector tabs; native close still saves, direct window close can lose newer state because headed browsers are exempt from idle shutdown, and explicit `AGENT_BROWSER_AUTOSAVE_INTERVAL_MS` opts in at daemon launch; its effective value persists across resume, and changing a running wrapper-owned headed daemon in either direction requires close plus a fresh launch. On 2026-08-06, a headed checkout dogfood run crossed `react.dev` → `example.com` → `react.dev`, idled past the autosave interval while recording, showed no temporary page switch in frame/contact-sheet review, and closed both sessions successfully; disposable evidence was removed. **Windows interactive desktop:** post-release validation on 2026-07-15 used a disposable clone of snapshot `57cc3c0d-7d7c-4a4c-9c57-8270d4174679`, a logged-in console session, `agent-browser 0.31.2`, and Edge 150. The headed doctor WebGPU render/readback subcheck passed in 0.99s and its decoded screenshot subcheck passed with `rgb(255,0,0)`; a separate `--webgpu --headed` launch opened the proof page and the Parallels console capture visibly recorded the red triangle (553,500 bright-red pixels; SHA-256 `f5a28f5336cbdfeb0ff557af9425458bddc6b266d3cc6b946de7b101a0b43288`). The full doctor remained nonzero only for the unrelated absence of a separately installed Chrome binary; the explicit Edge executable completed the launch and both WebGPU probes. Local evidence is under `.artifacts/windows-webgpu-interactive/20260715T150903Z/summary.json`; the disposable clone and temporary account were deleted afterward. |
| Crabbox platform smoke | `npm run check:platform-smoke` syntax-checks the harness and cheap invariants. `npm run smoke:platform:ubuntu-image` builds the project-owned Linux image, `npm run smoke:platform:doctor` checks Crabbox 0.26.0+ and local target readiness, and `npm run smoke:platform:all` runs doctor first, then fast target-local `platform-build` (`npm run verify -- platform-target`, pack, clean Pi install) plus `browser-dogfood-smoke` on Crabbox `macos`, `ubuntu`, and `windows-native`; see [`platform-smoke.md`](platform-smoke.md). Target artifacts include Crabbox/provider/work-root metadata, and release review also checks provider-specific `crabbox list` commands for leftover leases/clones. | **Current for 0.33.2 / package 0.3.0 / Pi 0.84.0:** static checks and local platform readiness passed on 2026-08-06. Ubuntu Crabbox passed both `platform-build` and `browser-dogfood-smoke`. macOS was attempted but blocked at SSH provider warmup for `mitchfultz@localhost`; native Windows was explicitly waived without installing or configuring Parallels. |
| `verify -- release` / `prepublishOnly` | `npm run verify -- release` chains the default gate with the configured-source lifecycle harness, packaged Pi smoke, and the release-blocking Crabbox platform matrix (`verifySteps` `release` in [`scripts/project.mjs`](https://github.com/fitchmultz/pi-agent-browser-native/blob/main/scripts/project.mjs)). `package.json` `prepublishOnly` runs that compose before `npm pack --dry-run` during `npm publish`. It intentionally omits standalone real-upstream and host-only dogfood modes—see [`RELEASE.md`](RELEASE.md#pre-release-checks). | **Package 0.3.0:** the composed release command was not run because macOS/Windows and isolated-model-auth prerequisites were unavailable or waived. Independent local, package, real-upstream, dogfood, and Ubuntu components were exercised. This release creates GitHub artifacts only; npm publishing is not authorized. |
| Configured-source lifecycle | `npm run verify -- lifecycle` (`scripts/verify-lifecycle.mjs`) drives `/reload`, closes and relaunches Pi with the same exact `--session-id`, checks the JSONL session header id, session continuity, slash-command sentinel tokens (`v1` before reload and `v2` after full relaunch because compiled JS package modules are process-cached), persisted spill reachability, and real Pi `tool_result` failure-patch semantics for a QA reclassification with a fake upstream on `PATH`. Default Pi model is `zai/glm-5.2`; default per-step wait is **180000 ms** (`DEFAULT_TIMEOUT_MS`); override model with `--model <id>` and waits with `--timeout-ms <ms>`. Passthrough flags in [`scripts/project.mjs`](https://github.com/fitchmultz/pi-agent-browser-native/blob/main/scripts/project.mjs): `--keep-artifacts`, `--model`, `--verbose`, and `--timeout-ms` plus a value (for example `npm run verify -- lifecycle --model openai-codex/gpt-5.5:minimal --keep-artifacts --verbose --timeout-ms 600000`). | **Pi 0.84.0 attempt on 2026-08-06:** environment-blocked before the first model response. Three isolated harness runs (`openai-codex`, `xai`, and Cloudflare AI Gateway) had no credentials inside the temporary `PI_CODING_AGENT_DIR`; no browser or extension assertion failed. The last green lifecycle evidence remains Pi 0.83.0 on 2026-08-03. |
| Quick isolated Pi smoke | `pi --approve --no-extensions --no-skills -e . --tools agent_browser` from trusted repo root; native `agent_browser` only. | **Current for 0.33.2 / package 0.3.0 / Pi 0.84.0:** pass on 2026-08-06 using the packed tarball as the only extension source. Native-tool form, navigation, QA, artifact, lookup, Electron discovery, download, and close paths completed; disposable sessions and artifacts were removed after transcript and image review. |

Runtime floor note: package metadata keeps optional Pi core package peer ranges wildcard per installed Pi package docs, pins direct Pi validation dependencies to 0.84.0, and makes `pi --version` below 0.84.0 a setup failure through `pi-agent-browser-doctor` / `npm run doctor`. The 0.3.0 support-floor change intentionally includes no compatibility shims for older Pi releases.
