See a feature in an app that you want in your own product? Give the app to your agent—even without its source code. With REA, the agent can investigate the feature, explain how it works, show its evidence, and build a version adapted to your stack and requirements.
REA gives agents one consistent way to investigate software. Today that includes deep native analysis and function dossiers through Hopper or bring-your-own Ghidra on Linux, plus an experimental Windows x64 Ghidra P0 for approved native PE applications; execution-free managed PE/CLI triage; reproducible Evidence v2 records; controlled process capture; passive website and Electron observation; bounded JavaScript/source-map reconstruction; and a versioned domain graph for connecting JavaScript application layers without confusing static inference with runtime observation. The longer-term toolkit extends the same agent workflow to APIs, protocols, mobile artifacts, firmware, richer runtime behavior, and differences between versions.

- Discover deep-analysis candidates without starting them, choose deterministically, and retain one immutable provider/profile binding until an explicit switch or close; provider failures never trigger transparent fallback.
- Attach to a user-owned Chrome-family browser over a configured loopback CDP endpoint; capture exact-origin web structure, safe metadata, approved value-free payload shapes, bundle/source-map evidence, WebMCP declarations, user-action timelines, capture diffs, and explicitly approved screenshots without navigation or JavaScript evaluation.
- Inspect Electron `file://` renderer pages through a separate canonical-root permission boundary without invoking Electron APIs; script contents remain separately approved and byte bounded.
- Attach to one exact approved Node or Electron V8 Inspector target and retain bounded `scriptParsed` plus execution-context lifecycle metadata without evaluation, breakpoints, resume, source reads, or instrumentation. require/import edges, EventEmitter activity, Electron IPC, PID identity, and role identity remain unknown. See [passive Node and Electron runtime observation](docs/javascript-runtime-observation.md).
- Validate and canonically serialize a provider-neutral [JavaScript Application Graph v1](docs/javascript-application-graph.md) spanning packages, ASAR entries, Electron roles, JavaScript/source-map entities, browser/runtime instances, IPC, endpoints, storage, and native add-ons. This shipped domain contract performs no extraction or I/O by itself.
- Reconstruct bounded static package, entrypoint, Webpack/Rspack module, import, worker, endpoint, storage, source-map, BrowserWindow, preload, contextBridge, IPC, utility-process, and native-add-on structure from an approved local directory or ASAR through `analyze_javascript_application` or `rea analyze-javascript-application`. The AST-only [application service](docs/javascript-artifact-reconstruction.md) never executes bootstrap code, pairs only unique exact literal IPC channels, and reports dynamic or ambiguous channels as unresolved.
- Reconcile that static graph with existing passive web or Electron Evidence through `reconcile_javascript_runtime` or `rea reconcile-javascript-runtime`. Exact captured bytes outrank caller-declared file/URL mappings; target, frame, script, worker, cache, and asset ambiguity stays explicit, source-map authority stays separate, and a module resident in an observed bundle is never reported as executed. See [JavaScript static/runtime reconciliation](docs/javascript-runtime-reconciliation.md).
- Trace a literal route, string, API, IPC channel, module, or native export through authenticated application Evidence with explicit traversal bounds, then hand exact native artifact digests and requested exports to retained Ghidra or Hopper Evidence without automatic provider switching. Compare application versions using unique-only digest, source-map, structural, and semantic tiers; compare one exact JavaScript export's static return shapes through unique literal discriminants and bounded JSON Pointer changes. Duplicate, dynamic, incomplete, and truncated facts stay unknown. See [cross-layer JavaScript application workflows](docs/javascript-application-workflows.md).
- Trace a literal route, string, API, IPC channel, module, or native export through authenticated application Evidence with explicit traversal bounds, then hand exact native artifact digests and requested exports to retained Ghidra or Hopper Evidence without automatic provider switching. Compare application versions using unique-only digest, source-map, structural, and semantic tiers; map a committed historical source inventory to bundle nodes with explicit digest and path scores; compare one exact JavaScript export's static return shapes through unique literal discriminants and bounded JSON Pointer changes. Duplicate, dynamic, incomplete, ambiguous, and truncated facts stay unknown. See [cross-layer JavaScript application workflows](docs/javascript-application-workflows.md).
- Classify PE/CLI managed artifacts with `inspect_managed_artifact` / `rea inspect-managed-artifact`, inspect bounded metadata members, signatures, raw CIL hashes, limited decoded-instruction-tuple v1 hashes, separately reported exception regions, call edges, and field-access anchors with `inspect_managed_members` / `rea inspect-managed-members`, inventory declared ModuleRef/ImplMap/PInvoke and non-IL method boundary indicators with `inspect_managed_native_boundaries` / `rea inspect-managed-native-boundaries`, then compare two authenticated member observations with `compare_managed_members` / `rea compare-managed-members`. `verify_managed_native_boundaries` / `rea verify-managed-native-boundaries` checks managed P/Invoke declarations against authenticated native export or function Evidence while keeping verified, inferred, contradicted, and unresolved states distinct. The comparison treats build-local tokens as build-local and uses unique decoded-CIL/signature and structural method-shape tiers, never names alone; the v1 tuple hash does not itself resolve tokens or fully commit control flow. `project_managed_application_graph` / `rea project-managed-application-graph` projects authenticated managed artifact/member/native-boundary Evidence into the existing application graph for cross-layer feature tracing. `import_managed_reconstruction` / `rea import-managed-reconstruction` admits user-supplied decompiler C#/IL/pseudocode as analyst inference only after exact artifact SHA-256, MVID, signature, and the shipped v1 decoded-IL commitment match. Separately, `plan_managed_runtime_correlation` / `rea plan-managed-runtime-correlation` can admit a default-disabled, permission-gated runtime-correlation plan locked to the same build evidence. These paths never load the assembly, resolve CLR dependencies, execute target code, run a decompiler, or translate managed tokens into native addresses; full normalized-CIL v2 semantics, native-body bridge mapping, and an actual runtime executor remain future managed-code contracts.

All eight browser tools expose the same Evidence v2 contracts over CLI and MCP. Inspection is passive: REA does not evaluate page JavaScript, navigate, click, close the page, or close the browser. Query values, credentials, cookies, authorization headers, storage values, and raw JSON or WebSocket values are never retained. Separately approved captures can retain bounded redacted console primitives, value-free JSON/WebSocket shapes, script sources, accessibility text, or screenshot pixels. Existing activity before attach is explicitly unavailable. See [Website observation with CDP](docs/browser-observation.md) for browser startup, schemas, limits, and the threat model.
### Controlled browser scenarios
`capture_browser_scenario` is a separate, explicitly mutating browser boundary.
It runs only the fixed, versioned scenario vocabulary through Playwright and
returns step-indexed Evidence for screenshots, DOM, accessibility, URL/history,
storage, console/errors, network, WebSockets, frames, workers, popups, and
cancelled downloads. Missing or truncated sections can never support equality
claims.
```bash
export REA_BROWSER_SCENARIO_ENABLED=true
export REA_BROWSER_SCENARIO_EXECUTABLE_ROOTS_JSON='["/usr/bin"]'
export REA_BROWSER_SCENARIO_CDP_ENDPOINTS_JSON='["http://127.0.0.1:9222"]'
export REA_BROWSER_SCENARIO_ALLOWED_ORIGINS_JSON='["http://127.0.0.1:3000"]'
export REA_BROWSER_SCENARIO_ALLOWED_ENV_JSON='["REA_TEST_PASSWORD"]'
rea capture-browser-scenario ./scenario.json --json
```
Launch mode owns a temporary browser profile and removes it after terminating
the launched browser. Connect mode accepts one exact loopback CDP target and
disconnects without closing the external browser. Automation has no default
grant: use the shared project/session policy, or set
`REA_BROWSER_SCENARIO_AUTO_GRANT=true` only for a trusted unattended
environment. Scenario JSON contains secret references and environment-variable
names, never secret values. See the
[browser scenario contract](docs/browser-scenario-contract.md).
### Node and Electron V8 Inspector observation
Attach-only JavaScript runtime observation is separately disabled by default:
```bash
export REA_V8_INSPECTOR_OBSERVE_ENABLED=true
export REA_V8_INSPECTOR_ENDPOINTS_JSON='["http://127.0.0.1:9229"]'
export REA_V8_INSPECTOR_FILE_ROOTS_JSON='["/absolute/path/to/app"]'
export REA_V8_INSPECTOR_ALLOWED_ORIGINS_JSON='[]'
rea list-javascript-runtime-targets http://127.0.0.1:9229 --approved --json
rea observe-javascript-runtime http://127.0.0.1:9229 TARGET_ID \
--runtime-kind node --approved --json
```
REA sends only `Runtime.enable` and `Debugger.enable`. It retains bounded,
scope-authorized script locations and execution-context lifecycle events;
require/import edges, EventEmitter activity, Electron IPC, PID identity, and
Electron role identity stay explicit unknowns. See
[passive Node and Electron runtime observation](docs/javascript-runtime-observation.md).
Exact package, tool-family, provider, setup-client, public schema-version, and CLI facts are generated from source in [`docs/product-catalog.json`](docs/product-catalog.json). PR CI verifies this catalog, narrative documentation, generated schemas, and a clean TypeDoc render.

# Browser scenario contract
`capture_browser_scenario` accepts the versioned provider-neutral
`browserScenarioSchema` through both MCP and the
`capture-browser-scenario INPUT_JSON` CLI command. Version 1 is declarative and
bounded: it admits a fixed action vocabulary, exact HTTP(S) origins,
deterministic browser settings, explicit storage and request replay, and finite
capture limits. `INPUT_JSON` may be inline JSON or a JSON file path.
The browser boundary is part of the contract. Launch mode requires a
caller-selected absolute executable, a provider-owned temporary profile,
headless operation, and close-plus-delete cleanup. Connect mode accepts only an
explicit-port loopback CDP endpoint, declares the browser externally owned, and
permits disconnect-only cleanup. The Playwright driver preserves this
distinction: it closes and deletes provider-owned profiles, but only disconnects
from an external CDP browser. Real-browser verification checks both outcomes and
confirms that an attached external browser remains alive.
URLs contain a query-free HTTP(S) base plus ordered query entries. Every query,
form, storage, cookie, and replay value is either an explicitly public literal
or a reference to a declared environment-backed secret. Raw credentials in
URLs and literal credential headers are rejected. Secret query names must also
appear in the redaction policy, and the required credential headers cannot be
removed from that policy. Durable results must replace resolved secret values
with their secret references.
Every start, navigation, storage, replay, and redirect origin must be listed in
`allowed_origins`. Unsupported action tags, unknown fields, duplicate step or
route IDs, undeclared or unused secrets, and provider-owned replay headers fail
validation. HTTP and WebSocket routing enforces the same declared scope. Exact
replay may abort unmatched requests or pass through only approved origins.
The result is Evidence v2 with an initial state followed by one record per
declared action. Each step reports action status, elapsed time, sanitized URLs,
event bounds, and independently typed capture states for screenshot, DOM,
accessibility, URL, history, and storage. Console, page-error, network,
WebSocket, frame, worker, popup, and cancelled-download events are attributed to
steps and bounded by the scenario limits. Missing and truncated sections remain
explicit and make the capture ineligible for equality claims. Attach-mode
captures also declare the unavoidable pre-attach event gap.
Browser automation is disabled by default. The administrator ceiling is
configured with:
- `REA_BROWSER_SCENARIO_ENABLED`
- `REA_BROWSER_SCENARIO_EXECUTABLE_ROOTS_JSON`
- `REA_BROWSER_SCENARIO_CDP_ENDPOINTS_JSON`
- `REA_BROWSER_SCENARIO_ALLOWED_ORIGINS_JSON`
- `REA_BROWSER_SCENARIO_ALLOWED_ENV_JSON`
Unlike passive observation, browser automation is not granted automatically.
Use an explicit project/session grant, or opt into the administrator grant with
`REA_BROWSER_SCENARIO_AUTO_GRANT=true` for a trusted unattended environment.
Authorization commits the exact executable or CDP endpoint, origins, environment
variable names, network class, and scenario digest before any browser side
effect.
## Scenario comparison
`compare_web_captures` and `compare-web-captures` also accept two complete
browser scenario captures. Steps align only by exact, unique `step_id`.
Duplicate IDs, missing counterparts, changed action kinds, and incompatible
browser/origin capture context are returned as alignment failures. They prevent
an unchanged claim; observed differences may still prove a changed result.
The comparison records its full normalization commitment and SHA-256 digest.
Built-in rules exclude step elapsed time and event sequence/index fields,
compare screenshots by content digest, and compare DOM/accessibility captures
by normalized text. Optional caller rules are bounded exact-literal
replacements over named artifact kinds. Rules and artifact-kind lists are
sorted canonically before application, making the same policy reproducible
regardless of input order. Rules operate only on already-redacted durable
capture fields and are preserved in the result.
Each aligned step reports changed, unchanged, or unknown. Changed and unknown
action, screenshot, DOM, accessibility, URL, history, storage, and event
artifacts carry their normalized before/after digests and capture states.
`max_changes` bounds retained artifact records while total and omitted counts
remain visible. Missing, truncated, or mismatched capture coverage remains
unknown instead of being treated as equality.

# Passive Node and Electron runtime observation
REA can attach to an already-running Node.js or Electron V8 Inspector target
and retain bounded script-load and execution-context metadata. The
`list_javascript_runtime_targets` and `observe_javascript_runtime` MCP tools
have equivalent `rea list-javascript-runtime-targets` and
`rea observe-javascript-runtime` commands. Successful calls return
deterministic Evidence v2.
This authority is disabled by default and is separate from browser CDP,
Electron file-page inspection, Process Capture, and controlled JavaScript
replay:
```bash
export REA_V8_INSPECTOR_OBSERVE_ENABLED=true
export REA_V8_INSPECTOR_ENDPOINTS_JSON='["http://127.0.0.1:9229"]'

--approved --json
rea observe-javascript-runtime http://127.0.0.1:9229 TARGET_ID \
--runtime-kind node --approved --json
```
At least one canonical file root or exact HTTP(S) origin is required.
Discovery is restricted to a literal-loopback HTTP endpoint. A target must
match the exact requested target ID, expose a same-port WebSocket reported by
the approved discovery endpoint, and remain inside the requested file or
origin scope. Targets already marked attached are rejected rather than
displacing another debugger. Canonical file paths are checked after symlink resolution.
Excluded locations are counted but never retained.
## Passive protocol boundary
The provider sends exactly two protocol commands:
- `Runtime.enable`
- `Debugger.enable`
It never sends `Runtime.evaluate`, reads script source, installs breakpoints,
pauses or resumes execution, calls `Runtime.runIfWaitingForDebugger`, launches
the target, instruments JavaScript, or invokes Electron APIs. Closing a call
closes only REA's WebSocket.
The direct observations are:
- `Debugger.scriptParsed`, establishing that a bounded script location was
parsed in the observed execution context;
- `Debugger.scriptFailedToParse`, retained only as a bounded invalid-script
count;
- `Runtime.executionContextCreated`,
`Runtime.executionContextDestroyed`, and
`Runtime.executionContextsCleared`, establishing context lifecycle within
the capture window.
The Inspector protocol does not directly expose require/import caller edges,
EventEmitter emissions or listener invocation, Electron IPC messages or
handlers, or script-unload events. Those facts remain explicit unknowns.
`scriptParsed` proves script presence, not the importing module, feature
execution, initialization order, or causality.
## Node and Electron roles
The caller declares one role: `node`, `electron-main`, `electron-preload`, or
`electron-renderer`. Node and Electron-main declarations require a protocol
target of type `node`; preload and renderer declarations require `page`.
Inspector does not authenticate the operating-system PID or distinguish an
Electron role, so Evidence records the role authority as
`caller-declared-unverified`.
Electron main, preload, and renderer behavior can therefore be observed only
as separate approved Inspector targets. The provider does not infer that two
targets belong to the same Electron application.
## Bounds and determinism
Every observation commits the window and exact limits for events, scripts,
execution contexts, per-location bytes, and total retained metadata bytes.
Limit hits increment dropped-event counts and set `capture.truncated`; they
never become completeness claims. Scripts are authorized after capture,
deduplicated by stable metadata, and canonically sorted. Wall-clock timestamps
and protocol script IDs are excluded from the durable result, so identical
inputs and captured metadata produce the same Evidence ID.
Inspector attach is inherently incomplete. Enabling `Debugger` reports known
and uncollected scripts, but scripts collected before attachment may be
missing. Absence from a bounded capture never proves that a script or behavior
does not occur.
## Static correlation
Pass the resulting observation Evidence and an
`analyze_javascript_application` Evidence record to
`reconcile_javascript_runtime`. The reconciliation accepts this provider
alongside passive web and Electron page captures. Exact approved file or URL
mappings can correlate script presence with JavaScript Application Graph
assets. Because this provider never reads source bytes, matches normally use a
unique authorized location and remain weaker than captured-byte identity.
Builtin `node:` scripts remain runtime-only nodes unless a future explicit
static authority models them.

Passive inspection retains the execution-context frame ID supplied by CDP

# Reconstruction obligation ledgers
`build_reconstruction_obligation_ledger` turns authenticated Evidence v2 records
into a versioned, deterministic list of reconstruction claims. The same workflow
is available as:
- MCP tool: `build_reconstruction_obligation_ledger`
- CLI command: `rea build-reconstruction-obligation-ledger`
- MCP resource:
`rea://evidence/{evidenceId}/reconstruction-obligation-ledger`
The ledger is conservative by design. Static Application Graph facts create
candidate obligations; they do not prove runtime or process behavior. A required
obligation closes only when one manifest binding supplies a unique owner, any
required parser/schema/domain type, every required case fixture, and a passing
verifier whose authority is comparable to the original observation. The
verifier must enumerate the obligation ID and its result must be present in the
input Evidence bundle. Contradictions, duplicate definitions or owners,
residual unknowns, missing dependencies, and unavailable authority keep closure
open or failed.
## Complete CLI request
This empty request is useful for checking client integration. It is valid and
returns an `unknown` ledger with zero obligations; absence of source Evidence
never claims closure:
```sh
rea build-reconstruction-obligation-ledger \
'{
"evidence_bundle": {
"bundle_version": 2,
"artifacts": [],
"providers": [],
"environments": [],
"scenarios": [],
"captures": [],
"unknowns": [],

"manifest": {

"bindings": [],
"contradictions": []
},
"limits": { "max_obligations": 100 },
"page": { "offset": 0, "limit": 50 }
}' \
--json
```
For a real investigation, export an Evidence bundle from the session and replace
the empty bundle. Application Graph and Process Capture v4 records generate
conservative candidates automatically. Add reviewed obligations when a required
claim is not represented by those sources.
## Reviewed obligation examples
Each example below is a complete `reviewed_obligations` element. Replace the
sample Evidence ID with an authenticated review record already present in
`evidence_bundle.records`. Stable IDs and versions make changes reviewable.

All referenced Evidence IDs must exist in the bundle. A green unit test cannot
close a `packaged-process` obligation. A static-only source cannot close a
runtime or process claim. Marking a claim `blocked` or `out-of-scope` records the
disposition but does not silently count it as verified.
Pagination changes only `page` and the returned `obligations` slice. Every page
retains the same `ledger_id`, `closure_digest`, full-ledger summaries, reports,
ownership graph, dependency graph, Evidence links, and limitations. Consumers
should follow `next_offset` until it is `null`, and should reject pages whose
identity or closure digest changes mid-read.

# Reconstruction readiness conformance
Run the complete source-owned native, JavaScript CLI, Electron, Evidence,
comparison, obligation, replay, CLI, and MCP journey from a clean checkout:
```sh
npm ci
npm run verify:readiness
```
The command builds the redistributable native conformance fixtures, inventories
the native executable through the public CLI, analyzes the generated JavaScript
CLI and Electron fixture through both CLI and MCP, verifies exact advertised
limits, evaluates the same nine-stage report through both surfaces, reads the
full MCP report resource, and proves stale/tampered replay rejection. It prints
one compact JSON summary.
Set `REA_READINESS_REPORT_PATH` to retain the complete machine-readable report:
```sh
REA_READINESS_REPORT_PATH=readiness-report.json npm run verify:readiness
```
CI runs this command on Linux, publishes the compact summary, and retains the
full report as the `reconstruction-readiness` artifact.
## Public contracts
- CLI: `rea evaluate-reconstruction-readiness <json-or-file> --json`
- MCP tool: `evaluate_reconstruction_readiness`
- Full MCP resource:
`rea://evidence/{evidenceId}/reconstruction-readiness-report`
The MCP tool result contains only report identity, status, summary, metrics, and
the resource URI. The full Evidence bundle, stage records, comparisons,
contradictions, obligation ledger, and replay inputs stay in the retained
resource instead of consuming the tool-response context.
## Required stages
| Stage | Required proof |
| ------------------------------- | --------------------------------------------------------------------------------------------------------------------- |
| `discover-classify` | target-free startup, artifact inventory, compatible workflow selection, and exact visible limits |
| `diagnose-environment` | broken runtime separated from analysis failure, version skew detected, and revision changed after recovery |
| `acquire-authority` | exact missing scope, narrow grant, expansion re-prompt, and no launch after denial/cancellation |
| `static-analysis` | native and JavaScript routing plus preserved ambiguity, truncation, unsupported syntax, and residual unknowns |
| `reactive-scenarios` | predicate-driven interaction, descendant settlement, Electron correlation, and cancellation cleanup Evidence |
| `compare-authority-candidate` | explicit partial-order/finite-trace semantics, primary divergence localization, and unknown for incomplete comparison |
| `preserve-contradictions` | record-and-continue, affected equivalence blocked, and unaffected comparison retained |
| `verify-reconstruction-closure` | incomplete reconstruction detected, incremental verifier closure, and authority-delegating candidates rejected |
| `export-replay` | CLI/MCP parity, process/structured failure parity, deterministic replay, tamper rejection, and stale-input rejection |
Every stage and required check must occur exactly once and link to Evidence in
the embedded Evidence v2 bundle. `fail`, `unknown`, `unsupported`, `truncated`,
and `skipped` never aggregate to `pass`.
## Fail-closed rules
The evaluator rejects or withholds readiness when:
- a bounded capability omits its effective numeric limits;
- a fixture lacks exactly one compatible selected workflow;
- an incompatible or unavailable provider was invoked;
- a typed CLI failure exits zero, or an MCP failure reports success;
- concurrent behavior uses total-order comparison;
- truncation, instability, unavailable authority, or contradiction is labeled
equivalent;
- a deliberate primary divergence is not localized;
- contradiction Evidence or its affected comparison is missing;
- the reconstruction obligation ledger is not `ready`, has no required
obligation, or retains an unowned/unverified required obligation;
- denied authority launches a process, cancellation loses diagnostics, or owned
resources remain;
- replay is nondeterministic, tampering/staleness is not detected, or the
expected source digest differs.
Each finding names its stage, stable reason code, Evidence IDs, and detail.
Stage `capability_issue` and `next_action` fields map unsupported or failing
work to the responsible capability and remediation without claiming that the
requested analysis ran.
## Fixtures
The verifier uses only source-owned, redistributable fixtures:
- `tests/conformance` native executables with stable symbols and deliberate
version divergence;
- `tests/conformance/readiness/javascript-cli`, which exposes prompts,
alternate-screen behavior, configuration precedence, child process,
persistence, loopback HTTP, and signal teardown to static reconstruction;
- `tests/conformance/readiness/electron`, which exposes main, preload,
renderer, utility, IPC, renderer restart, blocked shell effect, and deep-link
surfaces;
- the shared incomplete reconstruction and broken-runtime observations in
`RECONSTRUCTION_READINESS_EXAMPLE`.
The synthetic example is a public typed input, not a global equivalence claim.
It demonstrates that every deliberate fault remains represented in the final
report and that only comparable Evidence can close the associated obligation.
