The first outcome is a locally runnable, read-only investigator: given pinned repository base/head revisions, a repeatable app setup and approved user-journey expectations, it drives a browser, proposes reproduction steps and returns independently verified findings. No human Domscribe capture is required. GitHub signup/install, a hosted control plane, automatic issue/comment posting, scheduled infrastructure and optional application-fix PRs are later delivery layers; this slice does not claim them. + +Reuse existing Domscribe/browser/process capabilities, without requiring extra enriched tool calls or claiming superiority. Docker Cloud authenticated agent repair is still unqualified; do not retry unchanged provider authentication or imply a local Git worktree is a security sandbox. Pilot execution is local, for explicitly trusted repositories and synthetic test data. It uses the normal existing Codex CLI sign-in, without reading/copying credential values. + +## Input and user contract + +Add experimental private tooling in scripts/investigation, invoked with pnpm exec tsx scripts/investigation/run.ts --config= --out=. A strict version1 JSON config selects a local Git repository, base/head refs, install/start argv arrays, app subdirectory, startup timeout, agent deadline, and approved journeys. The start argv accepts a literal {port} replacement; the controller supplies a dynamic localhost port. Child commands are argv, never interpolated shell strings. No credentials in config or probe steps. Support plain React/Vue Vite apps initially, including an optional existing Domscribe integration/MCP entry point; do not claim zero-config support for every repo. + +Each journey has an id, intent and expected observations: a unique accessible target and expected text/value/checked state/count. These expectations come from the trusted operator/customer contract, not the agent. The pilot example uses synthetic business records. The agent can choose browser actions, but cannot change expected outcomes or assert its own conclusions as verified. Reading source, docs and relevant issue text helps discovery; the MVP takes a supplied product brief rather than independently trusting all historical issues. + +Refs are resolved to exact commits with option-safe Git argv. Base must be an ancestor of head. Create two detached Git worktrees under a new task-owned run directory; never modify the source checkout. Install/start both with bounded resources and cleanup. Capture commit IDs, diff digest, config digest and tool versions. Preserve failures as evidence. An unavailable installation/server/browser is blocked, not a passing investigation. + +## Agent proposal + +A fresh read-only Codex CLI session sees the isolated head source, base/head app URLs, bounded Git diff, supplied journey intent/expectations, and a full Playwright browser MCP. Optional Domscribe MCP adds runtime/source inspection; use it only if helpful. No browser-agent condition loses ordinary source or browser capabilities. No access to a hidden grader/known fix is needed. Use --ignore-user-config to avoid unrelated MCP servers; normal auth stays opaque. Record actual model metadata if emitted, otherwise unknown; do not infer model parity or token cost. + +The final structured response is a bounded version1 proposal listing one plan per covered journey and explicit uncovered journey reasons. Plans contain at most40 steps: click/fill/check/select with unique role/name locators and optional accessible ancestor scope. No arbitrary CSS, JavaScript, shell, URLs, browser storage mutation or agent-authored assertion code. The initial app URL is controller-selected; a navigate action accepts only a same-origin relative pathname. Password/file inputs are refused. Target ambiguity stops rather than choosing first/nth. App navigation/network are limited to the configured local test origins during independent verification. This is a narrow proof format, not universal browser automation. + +The agent must actually use its browser during discovery for a run to count as agent-investigated. A valid source-only proposal can still be recorded as unqualified. Domscribe tool usage is optional; its absence cannot be silently presented as evidence of benefit. + +## Independent browser verification and classification + +The controller validates the proposal and runs its declarative plans with trusted Playwright code. It creates a fresh browser context for base, head, and a second fresh head repeat. No reused storage or discovery browser state; no agent-modified source is graded. Compare expectations using real browser observations, preserving before/after screenshots and app console/page/network errors. Verify working trees remain clean, so editing the app or setup during discovery cannot manufacture a result. Do not package Domscribe artifacts while rebuilding them. + +A confirmed PR regression requires the approved expectation to pass on base and fail semantically on both fresh head runs, with all actions completing. The failing expectation and observed values must agree across both head runs. A valid journey failing on base is pre-existing; head action/setup failures, inconsistent repeats and missing plans are inconclusive/uncovered. A passing observation is evidence for that journey only. Do not report full-app health or new bugs simply because the agent says so. Expected behavior can intentionally change in a PR; the operator must keep the configured contract current. + +The report distinguishes confirmed regressions, pre-existing failures, inconclusive results and verified passing journeys. Stable fingerprints bind journey and expectation IDs to deduplicate equivalent findings within one report. Render one reviewable Markdown PR-comment draft with relative artifact links and clear tested scope. Do not post it, create issues, fix app code, publish packages or deploy. Findings are untrusted text; use fenced rendering and bounds. Private raw logs stay in the local mode0700 evidence directory; the comment draft omits account/workspace paths and raw agent transcript. + +## Validation + +First meaningful failing regressions cover fabricated/contradictory proposals, duplicate plans, unknown expectation IDs, base failures, action failures, inconsistent head repeats, unchanged/healthy heads, cleanup, unsafe refs/subdirectories and report bounds. Then implement the smallest working flow. + +Fresh real-browser acceptance must include a real app implementation with controlled PR commits: one business regression, one healthy/layout-only change, and a pre-existing failure control. These are deliberately constructed test changes, not organically discovered customer incidents. At least one fresh autonomous-agent discovery run uses the generic entry point and yields a controller-verified result without reporter capture or patch hints. Compare an optional Domscribe-assisted run only when the same scenario/tool access can be preserved; record parity limitations and setup work separately. Existing larger-app repairs are historical, not proof of this new investigator. + +Run new offline/unit/process/type/lint checks and existing affected checks, plus independent code review. Add offline tests to CI; live model calls are opt-in and not part of ordinary CI. Required latest-head CI must pass before standing-authorized merge. No new release is authorized. Report pilot limitations and next step toward a hosted customer experience, rather than implying that signup/repo onboarding already exists.

An agent browses the app and proposes reproduction steps. A separate browser executor replays them on base, head and a fresh head repeat against operator-approved expectations. It writes a local report and PR-comment **draft**; it never posts the draft or changes the app. + +This is an experiment toward PR investigation. There is no managed service, GitHub App, scheduled crawler, billing or automatic fix delivery in this slice. A local Git worktree and Codex read-only mode are **not a security boundary for arbitrary customer repositories**. Install/start commands execute trusted repository code with the local user's permissions. Use synthetic data only, on a machine/environment appropriate for that code.

The runner does not read or copy authentication values. The explicit `agent.model`/`agent.reasoningEffort` settings default to the locally tested `gpt-6.1-sol`/`low`; choose an available model for your account. Requested settings are recorded separately from unknown actual model metadata. It ignores unrelated user configuration/MCP servers and uses a fresh ephemeral read-only session. Agent/browser subprocesses, app startup, installs and the whole run have deadlines. Use a new output directory with an existing parent, outside the source repository; existing directories are refused. SIGINT/SIGTERM trigger cleanup. The primary source checkout is preserved; two detached worktrees are installed, started and then removed. + +Exit0 means **investigation completed for all configured journeys**, including confirmed regressions/pre-existing failures; it does not mean the PR is healthy. Exit2 means partial, blocked or source-only/unqualified investigation. Invalid configuration/pinning or fatal cleanup returns1. No live model calls run in ordinary CI. + +Copy [the TodoMVC configuration](../scripts/investigation/examples/todomvc.json) and set `repo`, `base` and `head` to your local repository/refs. Refs are pinned to exact SHAs; base must be an ancestor of head. `appRoot` is relative to the repository root and may not escape through symlinks. `install` and `start` are argument arrays, with `{port}` substituted into the start command. No shell interpolation or credentials belong in this configuration. The app must bind that exact localhost port and return a successful homepage response. + +The supplied brief and journeys are the product contract. The pilot does not independently learn the product by trusting all historical issues. Specify useful business outcomes, including the unaffected record when identity matters. A successful click alone is not a business assertion. Expectations are fixed by the operator; the agent cannot change them. + +## Reproduce the controlled Vue case + +The acceptance application is upstream [TodoMVC](https://github.com/tastejs/todomvc/tree/ff43b02e59dfa604386bb382034b2cd07c2bcd8a/examples/vue), with deliberate local test commits. These are controlled regressions, not organically discovered customer incidents. Create a local bare cache, then a detached worktree; do not edit an existing application checkout: + +```sh +git clone --filter=blob:none --bare https://github.com/tastejs/todomvc.git /tmp/domscribe-todomvc.git +git --git-dir=/tmp/domscribe-todomvc.git worktree add --detach /tmp/domscribe-todomvc-case ff43b02e59dfa604386bb382034b2cd07c2bcd8a +``` + +For a healthy control, compare the same commit, or commit a harmless heading class. For a regression control, make a local commit changing `event.target.value.trim()` in `examples/vue/src/components/TodoHeader.vue` to `event.target.value.trim().toUpperCase()`. Point the config's `base` at the preceding good commit and `head` at that local commit. The generic runner receives the PR diff and approved case-preservation contract, with no reporter annotation or hidden fix. It must discover the UI steps itself. For a pre-existing-failure control, separately configure the existing `todos` heading observation to expect `Tasks`; label this intentionally unmet test contract clearly. Never treat that control as a customer bug. + +## Results and evidence + +The private output directory is mode0700. It retains `report.json`, `comment.md`, `proposal.json`, a bounded diff, raw agent/app/install logs and browser screenshots. Raw logs/screenshots may contain repository/UI data: review before sharing. The draft omits raw transcripts and host paths; artifact links are relative local links, not hosted URLs. + +- **regression**: all actions complete, approved base observations pass, and the same expectations fail with the same actual values on both fresh head runs. +- **passed**: those approved observations pass all three runs. This says nothing about unexplored behavior. +- **pre_existing**: at least one approved observation already fails on base. The whole journey is conservatively excluded from PR attribution; split independent outcomes into separate journeys to avoid hiding a new failure behind an unrelated baseline failure. +- **inconclusive/uncovered**: action/setup/locator failure, missing plan, missing observations or inconsistent head results. These cannot become verified bugs or passing coverage. + +A schema-valid proposal without an actual completed agent browser call is marked unqualified. Domscribe usage is recorded separately and is optional. This pilot alone does not establish Domscribe's incremental value, reliability rate, cost advantage or demand. + +## Optional Domscribe inspection + +For an already instrumented synthetic-data app, install `@domscribe/mcp` as a direct app development dependency and set `domscribe: true`. The app's dev startup must start its relay/overlay integration normally. The adapter runs that app-local MCP entry point in the head app's directory. It does not install/inject Domscribe automatically. Compare against the same full browser/source workflow before claiming benefit. Published npm capabilities and local source pilot tooling are separate. + +## Current limits + +Plans support click, fill, check, select, Enter/Escape/Tab and same-origin pathname navigation. Targets use exact accessible role/name, optional literal visible-text filtering and one named accessible ancestor. Empty accessible names are explicit and still must resolve uniquely. No CSS/nth/first fallback, arbitrary verification JS, hover, double-click, file/password inputs, storage seeding, backend restoration or login restoration. Main-document controls and synthetic local app data are the qualified scope. Cross-origin assets/API dependencies are blocked during independent replay. Missing targets remain inconclusive, even when their disappearance might be a real regression. + +Each phase has a fresh browser context, but a persistent backend would still share server state; do not infer reset/independence of backend data. Observation waits are bounded, not proof that all asynchronous work finished. Console/page error counts are recorded and need interpretation; they are not automatically classified as PR bugs. Expected contracts can intentionally change in a PR and need human maintenance. + +```sh +pnpm exec tsx --test scripts/investigation/*.test.ts +pnpm exec tsx --test scripts/investigation/browser.browser.ts +pnpm exec tsc -p scripts/investigation/tsconfig.investigation.json +pnpm exec eslint scripts/investigation --max-warnings=0 +``` + +## Recorded acceptance, October27,2026 + +Two fresh autonomous runs of the generic CLI used actual upstream TodoMVC Vue at `ff43b02`, with deliberate local test commits: layout-only `add444d` and title-normalization regression `bb16774`. Both revisions were freshly installed using the upstream frozen `npm ci` path and replayed in separate browser contexts. No reporter annotation or seeded action plan was supplied. + +The regression comparison independently observed `Invoice review` on base and `INVOICE REVIEW` on both fresh head runs. The heading passed, while the deliberately wrong `Tasks` expectation was labeled pre-existing. The separate healthy/layout comparison passed both real expectations and reported no new findings. All18 independent observations completed, with zero recorded console/page errors and zero failed/HTTP4xx/5xx app requests. Qualification was also rechecked from successful MCP app-navigation events against app startup origins using the final parser. + +Environment: Node24.22.1, pnpm9.12.0, CodexCLI0.164.0, Playwright1.64.1, browser MCP0.0.83; requested model `gpt-6.1-sol`/low, actual provider model metadata unknown. The agent used ordinary browser/source access; **Domscribe MCP was disabled**. These controlled cases establish an executable investigation/reporting path, not product differentiation, organic bug discovery, broad coverage, efficiency or demand. + +Failed attempts were retained: API output-schema rejection; converted structured-output runs ending before tool use; a browser MCP approval gate correctly producing uncovered results; an overstrict sparse-index guard; and an Nx configuration-inference error. The final adapter validates ordinary final JSON locally and approves only the configured browser server within that invocation. A separate uncached overlay compilation failure was corrected by explicitly preserving the helper's optional-context return type. diff --git a/packages/domscribe-overlay/src/services/relay-service.ts b/packages/domscribe-overlay/src/services/relay-service.ts index 70f49d6..17b7c39 100644 --- a/packages/domscribe-overlay/src/services/relay-service.ts +++ b/packages/domscribe-overlay/src/services/relay-service.ts @@ -37,7 +37,9 @@ export class RelayService { private store: OverlayStore;

These browser controls are not an OS network firewall. Missing targets remain inconclusive, even when their disappearance might be a real regression. Each phase has a fresh browser context, but a persistent backend would still share server state; do not infer reset/independence of backend data. Observation waits are bounded, not proof that all asynchronous work finished. Console/page error counts are recorded and need interpretation; they are not automatically classified as PR bugs. Expected contracts can intentionally change in a PR and need human maintenance. @@ -62,12 +62,14 @@ pnpm exec tsc -p scripts/investigation/tsconfig.investigation.json pnpm exec eslint scripts/investigation --max-warnings=0 ``` -## Recorded acceptance, October27,2026 +## Recorded acceptance, October 27, 2026 Two fresh autonomous runs of the generic CLI used actual upstream TodoMVC Vue at `ff43b02`, with deliberate local test commits: layout-only `add444d` and title-normalization regression `bb16774`.
