Cursor Agentandmorluto c7183b654d fix(pe): reject truncated certificate tables and PKCS#7
SignedData now requires one SignerInfo with a non-empty signature and a
complete issuerAndSerialNumber. Certificate names share a 64 KiB decoded-byte
budget and are copied once. A security directory that ends in a short
WIN_CERTIFICATE header fails instead of reporting a complete table. The
certificate CLI forwards the caller abort signal into cleanup.

Matt Van Horn f5847a8ea9 fix(pe): cap OBJECT IDENTIFIER length and arc size
A crafted type-2 certificate with a 262,144-byte contentType OID stalled
decodeOid for about 20 seconds, because one arc kept growing a BigInt
before the signedData check ran. decodeOid now rejects an OID longer than
256 bytes and an arc longer than 32 bytes before decoding it. Certificate
OIDs, including 2.25 UUID arcs, fit under both caps.

Matt Van Horn 78c1c03815 fix(pe): bound and validate certificate DER decoding
- Cap decoded DER values with a shared node budget so sibling fan-out

- Require SignedData version, encapContentInfo and a final signerInfos
  SET in RFC 5652 order, and a signature OCTET STRING in each SignerInfo
- Decode OBJECT IDENTIFIER arcs as unbounded base-128 values, including
  a multi-byte first combined arc
- Decode UniversalString names as UTF-32BE and reject invalid values
- Share PE header admission with the resource layout so a section table
  that does not fit SizeOfHeaders is rejected

* fix(source): retain CommonJS requires spelled as exact no-substitution templates

Admit expression-free template arguments at the CommonJS require gate and
read their single cooked quasi through the shared exact-literal reader.
Scope is the require path only: static ESM template declarations keep their
parse failures and dynamic import() keeps the explicit unknown/partial
<dynamic-import> relationship with no invented target.

Refs: #4382

* fix(source): admit TypeScript-wrapped exact require arguments via the shared literal reader

Address review: the require gate matched the outer AST node, so
runtime-transparent TS wrappers (as const, !, satisfies) around exact
strings or expression-free templates were still silently omitted even
though readExactJavaScriptLiteral unwraps them. Remove the gate and let
the shared exact-literal reader own argument exactness; computed
arguments remain silent and dynamic import() behavior is unchanged.

7721d59e1a fix(adb): normalize absent installer package sentinels (#4073)
* fix(adb): report a null installer declaration as an absent installer

Package Manager prints its String fields by concatenation, so a package
without a recorded installer shows `installerPackageName=null` in
`dumpsys package`. The projection treated only an empty value as absent
and forwarded the text "null" as a present installer identity, which a
consumer cannot tell apart from a package literally named "null" (#3943).
`versionName` is printed the same way and had the same gap.

The parser now maps the empty value and the `null` sentinel of both
String fields to the nullable result's null at the producing boundary;
a reported installer such as com.android.vending is kept unchanged.

Validation: parser unit tests for the sentinel, empty and missing
installer lines and the absent version name, plus a provider-level
regression through the inspect_adb_package operation; three of them fail
on main and pass here. The issue's four CLI controls through
`rea inspect-adb-package` against a stub adb return JSON null for the
sentinel, empty and missing cases and keep com.android.vending. Typecheck,
lint and module boundaries pass.

Closes #3943

* fix(adb): keep the null sentinel handling to the installer field

Review feedback on #4073: a manifest can declare the literal string
"null" as android:versionName, and dumpsys prints it exactly like an
absent value, so mapping versionName to null would turn a real version
into absence. Only installerPackageName, where no package can carry that
name, treats the printed null as the absent installer. The test for the
version name now pins the retained text.

* test(adb): establish permission inventory in null-installer fixture

Main now reports partial coverage when the requested-permission
inventory is not established (9534e42ec). Give the null-installer
fixture a requested permissions section so it still checks a
complete projection.

76dbc32f39 fix(environment): bound state reads and retain cleanup ownership (#6158)
* feat(environment): extract the initial state a capture's reads observed

Add the environment-state analysis view. From the parents the environment
manifest accepts, it extracts the data the capture's reads observed before
the first related write: entity types with an identity field (proved by a
path parameter or inferred from an identity name), entities with their
recorded values and provenance, documents for written non-entity paths, and
a render plan per read tool that is kept only when it reproduces the tool's
latest initial recordings from the state; every other read tool is a
recorded view with the reason. The Evidence is always inferred.

Response-body decoding moves to a domain owner shared with replay, exact
JSON parsing moves to the owner of the exact-number policy, the manifest and
state views share parent admission and record grouping, and
projectAnalysisView takes its accumulators as one object.

* fix(environment): bound state at redacted writes; infer identity only from items

A scenario write whose URL was redacted has no request line, so it was
dropped and reads after it counted as initial state. Such a successful
write now joins the timeline with an empty path, whose root relates to
every type, so it ends every type's state; a limitation counts them.

A list whose recordings were all empty passed the "every listed item
carries it" check vacuously and published an identity field nothing
showed; it now needs at least one item, else the view stays recorded
as no-identity.

A value that differed between two request lines of one item tool, such
as a query variant, was called volatile, and the gate then substituted
each recording's own value; only repeats of one request line now show
volatility, so differing lines go through fields-differ.

List membership is compared only while a list can still be the whole
collection, and merged entities are indexed by type and collection once,
so paged captures no longer cost pages times entities (8,000 pages of
40,000 entities: 5.7 s to 0.23 s).

Docs and the tool contract say scenario state keeps the capture's
redaction markers and how redacted writes bound it.

* fix(environment): keep first sightings, one list pointer and linear field unions

Entities took the order of the first plan observed, and item plans run
before list plans, so a complete list read before its detail reads came
out reordered and lost "all" membership; each entity now keeps its
earliest recorded sighting.

A list plan reused the first recording's pointer for later recordings,
so a later response that was itself an entity wrapping a list was read
as that list; every recording must now locate the same list.

The field union scanned its ordered list for every key, quadratic in an
object's width; a set now answers membership.

Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

* fix(environment): keep post-write values and partial lists out of the initial state

A value that changed between repeats of one request line was named
volatile whenever no write under the type's own root lay between, so a
write under another root (for example POST /api/dashboards/db before a
second GET /api/search) left its effect in the initial state. Any
recorded write between the two observations now leaves every tool of the
type recorded with reason fields-differ instead.

A list was published with membership "all" even when a total or count
envelope member exceeded the number it listed. Such a counter now makes
the membership "recorded".

Also drop a stale doc comment on ObservedEntity.order.

* docs(environment): scope item-shaped and deleted written paths out of documents

State documents are held only for list-shaped paths a POST, PUT or PATCH
tool writes. Reads of item-shaped written paths and of paths that are only
deleted stay recorded views; the guide now says so and the spec defers them
to a later increment of #4933.

Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

* fix(environment): count writes in flight when a value changes between reads

The volatility check compared write start positions with the two reads,
so a write already in flight when the earlier read started was missed and
its effect was named volatile. A write now counts when its interval
overlaps the span from the earlier read's start to the later read's end.

The check also ran once per changed field and scanned every write. It now
runs once per pair of observations, answered by a binary search over the
writes in timeline order and the latest end among each prefix.

Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

* fix(environment): catch cross-tool changes across writes; read only item totals

A value that changed across a write was caught only between repeats of
one tool's request line, so a list read before a write and an item read
after it put the post-write value into the initial state. Changes are
now classified per entity in timeline order after observation: across
any recorded write, a change between repeats of a line or between two
lines of the type rewrites the type (every tool recorded as
fields-differ); with no write between, a repeat's change is volatile.
The classification lives in environmentStateMerge.ts.

Any numeric member whose name contained "total" or "count" counted as
an item total, so total_pages, account_id or page_count made complete
lists partial. Item totals are now members whose name tokens include
total or count and none of page, pages or per; a string of digits counts
as a number; and a set has_more, next or next-page token member also
marks the list partial.

* fix(environment): keep post-write observations out of initial state

* fix(environment): retain field provenance and bound state inference work

* feat(environment): serve tool calls from the environment state

`environment-serve --state <state.json>` serves an environment from the
initial state an environment-state view extracted. Read tools whose views
are state-backed answer from a live state store: item views render the held
entity into the recorded envelope, list views render the collection or the
recorded members, and document views return the held value; a missing entity
or one lacking a required field is refused, and requests the state cannot
answer fall back to their recordings with the reason. The /agentenv data
plane implements data/reset, data/add (a rea-state/v1 document as a data
part, base64 bytes, a file:// path or an https URL, validated and replaced
atomically) and data/get, and the card advertises those operations and an
intake declaration. Stage 1 is read-only: write tools are not served in
state mode. Without --state nothing changes.

* docs(environment): record verification after merging the state view's review fixes

Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

* feat(environment)!: serve the environment state by default

environment-serve derives the environment state at startup by running the
environment-state view in-process on the capture with the manifest's
template rules, so an environment comes with its state and a user supplies
nothing extra. The derived Evidence is the same one inspect-analysis-view
produces by hand. --state is removed; --replay-only serves exactly the
stateless replay of main. When the state cannot be derived, or its catalog
does not fit the discovery budget, the server starts in replay mode, logs
the reason and reports it in the stop summary's `state`. Exported bundles
serve the state by default too: export derives it the same way, so the
verifier's tool count and checked answer match what is served, and the
README describes the served mode.

BREAKING CHANGE: environment-serve answers read tools from the derived
state and does not serve write tools unless --replay-only is given; the
stop summary reports `state` instead of `state_evidence_id`.

* fix(environment): bound data-plane replies, keep batch order, cancel intake on stop

- One /agentenv response is held to 64 MiB: replies are measured as they
  are produced and one past the budget becomes a -32000 error stating it.
- Every message of a batch enters the arrival-order queue on arrival, so
  another request's reset never lands between them.
- Stopping the server, or a caller leaving, cancels the active download
  and answers queued calls `cancelled` without running them.
- file:// URIs name only this host: another host or a network share is
  refused before anything is opened.
- A loaded view value may not give an entity another identity.
- List answers refuse a member lacking a field every recording carried,
  as item answers do.

* fix(environment): keep bodies too deep for the state's nesting out of the state

A recorded body at the JSON depth limit was accepted by extraction, then
nested a few levels deeper as a document or entity value, so sealing the
state Evidence threw and environment-serve and environment-export stopped
instead of falling back. stateBodyJson, the one rule extraction and
serving share, now treats a body nesting deeper than the limit minus 16
levels as unusable, so its tool stays a recorded view.

Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

* fix(environment): measure data-plane replies before building them

83fcc739 bounded one /agentenv response to 64 MiB, but it still
serialized each reply whole before measuring it, so a batch of data/get
calls on a large state built every refused reply in full only to drop
it. Each reply is now measured in bounded JSON parts (the shared
jsonParts encoder), its parts kept only while it fits; a reply past the
budget is counted for its exact reply_bytes but never assembled. A test
checks that a refused read is never handed to JSON.stringify whole and
that its reply_bytes is exact.

Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

* fix(environment): release batch replies as they are encoded; judge exact numbers by value

answerBatch kept every settled reply in its pending array until the
batch ended, so a batch alternating data/add and data/get held each
loaded state alive; each reply now leaves the queue as it is encoded.

The exact-number policy judged a number by its recorded spelling, so a
state loaded with 1e20 came back from data/get as
100000000000000000000, which data/add refused, breaking the promise
that data/get output loads back unchanged. A number is exact only when
both its recorded spelling and the one serialization writes are safe,
so integers from 2^53 below 1e21 are refused in any spelling; replay
keeps such bodies as recorded text. A domain test checks that every
accepted number is accepted again once written back.

Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

* fix(environment): keep room for refusals and framing in the reply budget

The response budget counted accepted replies only: a budget error that
replaced a reply, and a batch's brackets and commas, were not charged,
so near 64 MiB later refusals pushed the body past the advertised
limit. Every reply still to come now keeps room for its own budget
error, and a batch keeps room for its framing, so a refusal always fits
and the body never passes the budget. Reply ids and which messages are
answered come from one place shared by the replies and the reserve.

Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

* fix(environment): refuse a loaded state that data/get would write past the intake limit

data/add measured only the document it was given, while data/get
writes the state back with the members a document may omit (types, the
state Evidence id, view fields and record citations). A document just
under 32 MiB could therefore load and be reported larger than any intake
accepts, breaking the data/get then data/add round trip. replace now
measures the state as data/get writes it, part by part, and refuses it
past the limit, leaving the state unchanged. The limit moves to the
state document module, so the application store can read it; the
intake re-exports it.

Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

* fix(environment): keep merged export checks on the shared test graph

Main's export tests installed module mocks for the whole services
project, which reuses one module graph. A tarball read failure then
missed its importer, and a one-shot heap mock could be taken by another
file. Read those through bindings the tests replace for one case.

* fix(environment): keep a state file whose close failed owned until it closes

A file:// data/add that could not close its descriptor dropped the handle,
and an admission failure whose cleanup close failed dropped its owner, so
nothing could retry the close or report it.

The read now runs through withOwnedRegularFile, and a failed close is
retained in a server-lifetime ArtifactResourceScope. The next file read
retries it first and answers -32000 while it is still open; inline and
https documents still load. Closing the served environment retries it again
and rejects with the unfinished close.

# PE Authenticode certificate tables
`inspect_pe_certificates` / `inspect-pe-certificates` answers whether one
selected local PE32/PE32+ image declares an `IMAGE_DIRECTORY_ENTRY_SECURITY`
table, which `WIN_CERTIFICATE` entries that table stores, and which PKCS#7
signer and X.509 fields those entries carry. It reads the file without
executing it and does not require a Windows SDK, catalog file, or disassembler.
```bash
rea inspect-pe-certificates /absolute/path/to/application.exe --json
```
The CLI resolves relative paths against the caller's working directory. MCP
requires an absolute filesystem path and preserves that exact selection:
```json
{
"name": "inspect_pe_certificates",
"arguments": { "path": "/artifacts/application.exe" }
}
```
## Observations
The inline Evidence result contains the artifact path, SHA-256, and byte length.
`table` is the file-offset security directory, or `null` when the directory is
absent or zero. Each `entries[]` item reports `WIN_CERTIFICATE` length,
revision, type, and the payload SHA-256.
For `WIN_CERTIFICATE` type 2 (PKCS#7 signedData) `pkcs7` contains digest
algorithm OIDs, embedded X.509 serial/issuer/subject/validity fields, and
signer identifier facts. Other certificate types keep `pkcs7` null.
A missing table is observed absence of that directory. It is not proof the
image is unsigned in every catalog or overlay sense.
## Limits and failures
The selected file is limited to 64 MiB by default (512 MiB maximum). At most
eight `WIN_CERTIFICATE` entries are examined by default. Malformed PE headers,
truncated certificate entries, and PKCS#7 that is not structurally signedData
fail without partial success. A security directory that ends in fewer than
eight header bytes, including zeros, is a truncated `WIN_CERTIFICATE` and
fails the same way. SignedData must contain at least one `SignerInfo`, and
each `SignerInfo` must carry a non-empty signature value. Decoded certificate
name text shares a 64 KiB budget per PKCS#7 payload.
This workflow does not verify signatures, certificate chains, timestamps, or
Authenticode digest coverage of image bytes.

Oversized or malformed evidence returns no partial successful result. Each command and the complete inspection/source-join phase use `command_timeout_ms` (default 20000). Cleanup uses a separate 5000 ms grace; `command_timeout_ms` does not raise or shorten it, and this release has no runtime override for that grace. Transport closure follows the grace. The selected observation duration must fit the host timer's positive 32-bit millisecond range. REA does not control the externally owned browser's CPU or memory.
`npm run verify:browser:runtime` uses caller-supplied `REA_BROWSER_EXECUTABLE` and the native `ps` command on Linux/macOS against an owned synthetic fixture, through real public CLI and stdio MCP. It checks exact Unicode/CRLF text/digests, same-URL identities, same-document navigation, inert declared names, executed and zero-count branches, function-only unknowns on repeated observation, listener selection, initiator association, actual arming and preservation of the external page. A separate fixture page closes during an armed MCP window to verify prompt termination and inline cleanup diagnostics. The optional positional entrypoint to `scripts/verify-browser-runtime.mjs` permits the same checks against an isolated installed tarball.
