22f28644fe feat(artifacts): inventory and extract Deno compile executables (#8527)
* feat(artifacts): inventory and extract Deno compile executables

Adds Deno standalone artifact support for Mach-O, ELF, and PE carriers,
exposing virtual files, entry points, recorded options, and file digests
without running the executable. Extraction uses the existing safe output
tree, preserves symlink targets as metadata, and assigns indexed paths
to unsafe or oversized names. Environment-file values and certificate
bytes remain in local Evidence; npm snapshots are reported by length
without decoding. The documentation describes supported layouts, parsing
limits, and refusal behavior.

* fix(artifacts): resolve nested Intel Deno carriers to the enclosing app

The backward trailer search stopped at the first confirmed sentinel, so an
Intel app storing another Intel Deno executable as a virtual file reported
the inner app. Search to the slice start, drop sentinels inside a confirmed
payload, and fail closed on side-by-side trailers that differ.

Correct the docs on retained environment values and generated regions.

* fix(artifacts): keep Deno coverage, remote paths and PE resources truthful

Report unknown coverage when the virtual filesystem cannot be listed, keep
resolved specifiers when another remote ID is missing, and percent-encode
characters in remote paths that a Windows destination would refuse. Reject a
directory at the PE resource language level, and correct the guide's
description of colliding generated regions.

* fix(artifacts): normalize Deno remote escapes so hex case cannot collide

Uppercase every percent escape in a generated remote path, so specifiers that
differ only in escape case reach the path registry as one name and the second
gets an indexed path instead of colliding on a case-insensitive disk.

* fix(artifacts): fail closed on truncated enclosing Deno trailers and encode reserved remote path characters

The Intel trailer scan rejected an overlong sentinel before reading its
marker, so a truncated enclosing app vanished and the nested app was
reported. Read the marker first and fail closed when a confirmed overlong
trailer encloses another trailer.

encodeURIComponent leaves `*` alone and the sanitizer covered only part of
the Windows reserved set. remoteDestination now encodes the whole set once
as uppercase percent hex; source_path keeps the original.

* fix(artifacts): defer truncated Intel Deno trailer failure until enclosing trailers resolve

A damaged Intel asset stored before a valid one inside a valid app made the
backward trailer search fail before it reached the outer trailer. Hold that
failure until the search ends and drop it when a confirmed enclosing trailer
holds the sentinel as data.

* fix(pe): fail closed when a resource type branch is unreadable beside a found name

namedResourceTargets skipped a type branch whose names directory, or a
name entry whose string, could not be read. A duplicate RT_RCDATA entry
pointing out of bounds therefore vanished once another branch matched,
and locatePeResourcePayloads returned only the readable ranges while
parsePeResources rejected the same tree.

The walk now records unresolved branches. hasPeResourceName still
reports false for a tree that never reaches the name, but once
locatePeResourcePayloads finds the name it raises a format failure if
any branch was left unresolved.

* fix(artifacts): skip Intel Deno sentinels that a native segment maps

A non-Deno x86_64 Mach-O that stores an Intel Deno executable in __DATA
had the asset's trailer promoted to the root application, because the
backward sentinel search never checked who owned the bytes it scanned.

locateMachOSlice now records the file ranges of every segment other than
__SUI and __LINKEDIT (libsui extends __LINKEDIT over the trailer), and
the Intel search skips any sentinel inside one of them. A slice whose
load commands do not frame stays with native inventory, since ownership
cannot be shown there.

* fix(artifacts): reject a universal Deno image with an unreadable sibling slice

The universal Mach-O locator skipped any slice whose load commands could
not be read or framed, and any slice with a FAT range issue. When another
slice confirmed Deno, that slice was reported as the whole image, so a
sibling declaring a different Deno application went unexamined.

locateMachOSlice now reports why part of a slice was not examined
(unreadable or unframed load commands, a truncated slice, or the Intel
sentinel allowance). locateMachO collects those reasons for every
declared and hidden slice and fails closed once any slice confirms a
Deno section. With none confirmed, the image stays with native inventory
as before.

* fix(scripts): supervise the Deno verifier version check

Run `deno --version` through the verifier command owner with a deadline
instead of raw execFile, and close the owner when the version is refused.

* fix(artifacts): keep unconfirmed Deno carriers native and fail truncated Intel trailers

An ELF SUI note whose descriptor is too short for the full d3n0l4nd name
now stays unconfirmed instead of failing closed; failures after the name
matches still fail closed.

Every marker-confirmed Intel trailer whose payload runs past the slice is
now kept until the backward search ends and fails unless an enclosing
payload contains it, so an Intel Deno app missing its last byte reports a
Deno failure instead of native inventory.

The Deno MCP boundary test now calls open_binary and inspect_artifact
through artifactMcpCall, as docs/testing.md requires.

* test(deno): drop source-text checks from verifier pin test

Keep the wrong-version subprocess check, which covers the pinned
release through behavior, and stop asserting on the verifier script's
source spelling.

* test(deno): close readers in finally in symlink and cancellation tests

A failed assertion or read error in either test skipped reader.close(),
leaving the file open while temp-directory cleanup ran. Both tests now
close the reader in finally, as CONTRIBUTING.md requires. The
closed-reader assertion in the symlink test stays after the finally.

* docs(specs): add deno-standalone spec, plan and tasks

Add docs/specs/artifacts/deno-standalone/ with spec.md, plan.md and
tasks.md for the Deno compile executable reader, as AGENTS.md requires
for a feature, and list them in the specifications index.

* docs: list the Deno compile guide in the documentation sidebar

* fix(deno): confirm the d3n0l4nd section before claiming Mach-O damage

A __SUI segment alone no longer makes later load-command damage Deno's.
A Mach-O whose __SUI segment holds only a differently named section now
stays absent and keeps native inventory, while damage seen before or
beside a confirmed d3n0l4nd section still fails closed.

* fix(deno): keep a slice with an unparsed segment command unread

A Mach-O segment command that frames but cannot be parsed may be the
__SUI segment, so the slice is no longer treated as fully examined. A
universal image whose other slice confirms Deno now fails closed instead
of letting that sibling supply the whole inventory, and with no confirmed
sibling the image still keeps native inventory.

* fix(deno): confirm an ELF SUI note before rejecting its length

A SUI note whose descsz runs past its note table was recorded as plain
damage before its descriptor name was read, so a malformed Deno carrier
fell back to native inventory. The owner and the d3n0l4nd name prefix are
now read within the table apart from the claimed extent, and a confirmed
note with an oversized extent fails closed.

* fix(deno): confirm a truncated __SUI section record by its name

A section record cut short after its 16-byte name was skipped, so a
damaged Deno carrier fell back to native inventory. The name is now read
apart from the rest of the record, and a truncated record that names
d3n0l4nd fails closed. The range checks for a confirmed record move into
their own helper.

* fix(deno): reject nonzero bytes after the last ELF note

When fewer than 12 bytes remained in a note table after its last note,
the walk stopped without looking at them, so a Deno note was selected
with complete coverage beside unaccounted data. The remainder is now
read: zero padding is accepted, and nonzero bytes are recorded as damage,
which fails closed once a SUI note is confirmed and otherwise leaves the
ELF to native inventory, matching the native note parser.

* fix(deno): validate FAT slice identity before choosing the search

The locator took a universal slice's CPU type from its FAT row, so a row
that called an x86_64 slice arm64 skipped that slice's Intel trailer and
let the arm64 payload stand for the whole image. Each slice's header is
now checked against its row with validateFatSliceIdentity. A mismatch
leaves the slice unread, so a universal image whose other slice confirms
Deno fails closed. The Intel fixture header now states
CPU_SUBTYPE_X86_64_ALL so its FAT rows can match it exactly.

* fix(deno): check the Intel trailer marker before judging its length

A trailer length word of 2^53 or more was dropped before its d3n0l4nd
marker was read, so an enclosing app with that length was skipped and a
nested app's range stood for the whole image. The marker is now read
first, and a marker-confirmed trailer whose length runs past the slice,
safe or not, joins the deferred truncated candidates and fails closed
unless an enclosing trailer holds it as data.

* fix(deno): count short ELF note tables against the note allowance

A note table shorter than one note header made a read of its trailing
bytes but counted no note, so many distinct tiny tables could force one
sequential read each past the 256-note allowance. Every nonempty table
now counts at least one entry, both in the up-front estimate and while
scanning, so an image past the allowance records the limit instead of
reading every table. The trailing-byte check moves into its own helper.

* fix(deno): fail closed on ELF extended section numbering beside a SUI note

A zero e_shnum with a nonzero e_shoff moves the section count into
section zero, so the section table was skipped and its SHT_NOTE tables
were never compared. Record it as damage, as PN_XNUM already is, so a
confirmed SUI note fails closed instead of reporting full coverage.

* fix(deno): keep undersized Intel trailers until enclosing ownership is known

A trailer length word below 8 was dropped before its d3n0l4nd marker was
read, so an enclosing app with a length of 0 to 7 was skipped and a nested
app's trailer was selected as the root. The marker is now read first, and a
marker-confirmed trailer too short to hold it is kept as malformed and fails
closed unless an enclosing trailer holds it as data.

* fix(pe): treat non-directory RT_RCDATA branches as unresolved

A duplicate typeId root entry whose target is a data entry was skipped
without marking the walk unresolved, so locatePeResourcePayloads returned
the readable named resource as complete. Route non-directory type
branches through the same unresolved path as unreadable names
directories so the Deno reader fails closed.

* fix(deno): fail closed on a zero-fill d3n0l4nd Mach-O section

denoSectionRange admitted the declared offset and size of a confirmed
__SUI,d3n0l4nd record without checking its section type, so a
S_ZEROFILL, S_GB_ZEROFILL or S_THREAD_LOCAL_ZEROFILL section could be
read as a file payload while MachoImage reports it as not file backed.
Reject zero-fill types with the shared isMachoZeroFillSection predicate
before assigning a physical range.

* fix(deno): bound the d3n0l4nd Mach-O section by its segment file extent

denoSectionRange checked a confirmed __SUI,d3n0l4nd record only against
the slice and file bounds, so a section reaching past its segment's
fileoff/filesize was still read as a complete payload while MachoImage
reports the same section as not file backed. Reject a section outside
its enclosing segment's file extent before admitting the physical range.

* style(deno): apply oxfmt to the DenoStandaloneLocation embedding union

* fix(artifacts): preserve Deno carrier ownership

* fix(artifacts): admit Deno parent segments

* fix(deno): preserve native segment ownership

* test(deno): cover mismatched Mach-O segment widths

43f06eb1e8 feat(native): recover ELF function ranges from unwind tables (#9585)
* feat(native): recover ELF function ranges from unwind tables

inspect_elf_unwind_ranges and inspect-elf-unwind-ranges read .eh_frame
and .eh_frame_hdr from one local ELF32 or ELF64 image and list the
function ranges its FDEs name, with CIE facts, LSDA and personality,
the containing section and an exact symbol where one starts at the
address. Nothing is executed and no disassembler is needed. Pointer
encodings follow the DW_EH_PE rules with raw zero as null, discarded
FDEs are counted and skipped, the .eh_frame_hdr search table is
compared with the decoded FDEs, and record, row and symbol budgets are
bounded. verify:elf:unwind-ranges compares the reported starts with
llvm-dwarfdump or readelf on a compiled C++ program.

* fix(elf): keep unresolved unwind facts out of reported ranges

Skip FDEs whose initial location is indirect and do not locate
.eh_frame through an indirect eh_frame_ptr, since pointer slots are
not functions. Stop an unbounded header-located scan at a CIE with an
unrecognized augmentation, report ignored duplicate PT_GNU_EH_FRAME
headers as incomplete coverage, and accept a null personality stored
under an indirect encoding.

Keep only symbols at decoded FDE starts, cache name observations per
string-table offset, and decode names only for the returned page under
a fixed 16 MiB text allowance, so repeated or long names no longer
grow memory with the symbol count.

* fix(scripts): run the ELF unwind verifier under owned process trees

Launch probes, compiler drivers, the stripper, the frame dump and the
inspection through createVerifierCommands, as verify-binary-hardening
does, so a timeout or interrupt stops the whole tree. The temporary
directory is removed only after the owned commands have closed.

* docs(elf): move ELF unwind ranges guide under docs/guides/native

The documentation guide assigns analyst workflows to docs/guides/<domain>/.
Move the guide there, place its navigation and directory entries in the
Native binaries group, and update links from the docs index, CLI guide,
spec and authored skill. The public /elf-unwind-ranges route is unchanged.

* fix(elf): give unwind text limits their own recovery and skip indirect tables

Throw a dedicated failure when a page's symbol names exceed the 16 MiB
text allowance, and map it to a resource error that tells the caller
to request a smaller limit rather than raise max_ranges.

Read a CIE augmentation with one bounded NUL search and keep it as a
byte view, decoded only for returned CIEs, so a long augmentation is
never built up character by character.

Leave an .eh_frame_hdr search table with an indirect encoding unread:
the header is incomplete, the comparison is unavailable, and the table
no longer bounds a header-located .eh_frame scan.

* fix(elf): resolve header count and table forms and name IFUNC resolvers

Leave a non-zero .eh_frame_hdr FDE count under an indirect encoding
unresolved, since it is the address of a slot that is not followed, and
mark the header incomplete without reading the table.

Treat a DW_EH_PE_omit table encoding as an omitted search table before
testing the indirect bit, so a header that declares a count without a
table stays present with complete coverage, and accept that form in
output validation.

Match STT_GNU_IFUNC symbols at exact FDE starts after function symbols,
with a limitation that the name is the resolver, not the implementation
it selects at run time.

* fix(elf): require allocated unwind pointer bases

* fix(elf): map unwind header relative base

* fix(elf): validate unwind load mappings

* test(elf): cover mapped nonallocated frame agreement

f21fda0fc0 feat(elf): report a Linux kernel image's version banner and embedded build config (#9573)
* feat(elf): report a Linux kernel image's version banner and embedded build config

inspect_kernel_build_config and inspect-kernel-build-config read one
local vmlinux, raw arm64 Image, gzip bzImage or zImage, or configs.ko
and report its Linux version banner and the IKCONFIG .config embedded
between IKCFG_ST and IKCFG_ED, without executing it. A config is present
only when a gzip member ends exactly at IKCFG_ED, passes its CRC-32 and
ISIZE checks and parses as .config text; framing that fails is reported
malformed, never absent. bzImage gzip payloads are inflated within a
budget and other codecs are named as unsupported, using codec detection
now shared with the kernel module parser. The config search, inflate
sizes and option counts are bounded, scans honor cancellation, and
target-derived text is marked untrusted.

* fix(elf): reject a gzip member whose header checksum fails

When FHCRC is set, compare the low 16 bits of the header CRC-32 before
inflating, so a damaged header no longer yields a present config or an
inflated bzImage payload.

* fix(elf): detect the bzImage codec inside the declared payload

Codec detection now reads the same payload_offset/payload_length slice that
is inflated, so bytes past a short payload cannot name its codec.

* fix(elf): report a framed config that does not decode as malformed

A damaged or cut-off deflate stream between IKCFG_ST and IKCFG_ED was
skipped and could end as an absent config with complete coverage. It is
now malformed with config_gzip_invalid, and a later valid config still wins.

* fix(elf): scan config lines in place and accept long string values

Config text is read one line at a time instead of split into an array, and
a quoted value is validated before it is decoded once. The 4096-character
string cap is removed: Kconfig has no such limit and max_config_bytes
already bounds every line, so a long CONFIG_EXTRA_FIRMWARE list is no
longer reported as malformed.

* fix(elf): let a live cancellation reach the kernel config parser

The parser ran synchronously, so an abort raised during parsing could not
change the signal before it returned. Inflation now runs on the zlib thread
pool and each scan yields to the event loop once per MiB, so the existing
cancellation checks observe a real abort.

* refactor(elf): carry the refused kernel config budget as a typed fact

Budget failures are now KernelBuildConfigBudgetFailure with a knob field,
and the provider builds its recovery advice from that field instead of
searching the diagnostic message for an option name.

* docs(elf): move the kernel build config guide under docs/guides/native

The documentation guide assigns analyst workflows to docs/guides/<domain>/.
Move the guide there, place its navigation and directory entries in the
Native binaries group, and update links from the docs index, CLI guide,
spec and authored skill. The public /kernel-build-config route is unchanged.

* fix(elf): yield while checking one long config line

A config made of one long quoted value never reached the per-line yield, so
the control-byte check, value validation and SHA-256 ran in one synchronous
block. Each now works one MiB window per event-loop turn, and the line
patterns match only a bounded name prefix instead of the whole value.

* fix(elf): return paged config entries that do not pin the decoded text

Entry names and values were V8 slices of the whole decoded config, so a
one-entry page kept the full text alive. Entries in the returned page are
now standalone copies, so retained memory follows the page size.

* fix(elf): yield while kernel marker searches find nothing

IKCFG_ST, IKCFG_ED and banner searches used one Buffer.indexOf over the
rest of the image, so a large image with no marker never yielded. They now
search overlapping one MiB windows and yield after each window without a
match.

* fix(elf): preserve long kernel config names

* fix(elf): frame kernel configs by gzip member boundaries

Matt Van HornandMatt Van Horn 645735fc0f feat(windows): inspect Shell Link (.lnk) shortcut files (#7859)
* feat(windows): inspect Shell Link (.lnk) shortcut files

Add inspect_windows_shortcut / inspect-windows-shortcut to read one
local Shell Link without resolving or executing the target. The report
keeps header flags and FILETIMEs, IDList items, LinkInfo volume and
network names, StringData, ExtraData including Tracker droid facts
labelled derived, and derived observations such as argument length
and a minimized ShowCommand.

* fix(windows): tighten Shell Link string reads and coverage

- Decode counted StringData over its full CountCharacters payload.
- Locate LinkInfo string terminators before charging max_string_bytes
  and before decoding; an unterminated string is a coverage issue.
- Mark an IDList without a TerminalID and an out-of-range
  LinkInfoHeaderSize as partial coverage.
- Report arguments_present and argument_length as null when
  HasArguments is set but the field could not be read.
- Derive target_extension from the joined base path and suffix.
- Keep ISO dates for FILETIME and UUIDv1 timestamps before 1970.
- Retain the completed file snapshot on parse failures.
- Reject an empty CLI path before normalization.
- Select the shortcut contract from its family in focused tests.
- Fixture StringData no longer writes a NUL into the counted payload.

* style: format docs index and Shell Link boundary type

Apply oxfmt to the two files format:check reports so Static checks passes.

* fix(windows): reject network share paths for Shell Link reads

inspect_windows_shortcut is advertised as offline, but the Windows path
schema admits UNC paths, and lstat on one can contact an SMB server and
offer the caller's credentials.

Reject UNC, extended UNC, and other host-prefixed device paths in the
provider before any filesystem call. Extended drive paths such as
\\?\C:\x stay allowed. A mapped network drive cannot be told from a
local drive by its path, and the docs say so.

* fix(windows): decode Unicode Shell Link file-entry names

File-entry items with bit 0x04 of the type byte, such as 0x36, store a
UTF-16LE name, but the parser always read it as Latin-1. The read stopped
at the first zero byte, so report.exe became r and an IDList-only
shortcut reported the wrong target_extension. Read those names as
UTF-16LE.

* fix(windows): read volume labels by exact Shell Link discriminator

VolumeLabelOffset 0x14 selects VolumeLabelOffsetUnicode and is not itself a
label offset, and that Unicode field exists for no other value. The parser
treated any offset of 0x14 or more as having both, so a Unicode-only label such
as "OS" also produced a false ANSI label "O", and an ANSI label stored past 0x14
had its own bytes read as a Unicode offset.

Branch on the exact value in parseVolume, the one place that interprets it, and
report a VolumeID too short to hold the selected field. The fixture wrote both
encodings for a Unicode volume, which hid the false label, so it now writes one.

* fix(windows): limit network share rejection to Windows hosts

POSIX hosts read repeated leading slashes as one local root, so an
accepted selection such as ///tmp/shortcut.lnk is a local file there.
Apply the host-prefixed path check only on Windows, and take the
platform through the provider constructor so the Windows path forms
stay covered on every test host.

* fix(windows): compare shortcut icons only against full paths

A stored IDList filename or relative path cannot show that an icon at a
full path is elsewhere, so the comparison reported a false difference.
Report null unless the icon and a recorded target are both full paths,
and assert the missing TerminalID issue by code and offset instead of
its message.

* fix(windows): keep unread ExtraData blocks unknown

A walk that stopped before or inside ExtraData still reported the blocks
that HasExpString and HasExpIcon expect as absent, though they were never
checked for. Report a block as absent only after the TerminalBlock shows the
section was read in full. Without one the block stays unknown and coverage
stays partial.

* fix(native): ignore LNK network provider type unless ValidNetType is set

CommonNetworkRelativeLink NetworkProviderType is only meaningful when the
ValidNetType flag (0x2) is set. Return null otherwise.

* fix(native): accept any ExtraData TerminalSize below 4 as the terminal

MS-SHLLINK requires TerminalSize to be less than 4, not exactly 0. Treat
1, 2 and 3 as the terminal block instead of a malformed block.

* fix(native): derive shortcut target facts from the stored environment target

Include the EnvironmentVariableDataBlock literal target among the target
candidates for target_extension and the icon comparison. Variables are not
expanded and the target is not opened.

* fix(windows-shortcut): keep unexpanded variable paths unresolved in icon comparison

A stored environment target such as C:\Users\%USERNAME%\app.exe could be
compared as different from C:\Users\Alice\app.exe. Variable-bearing paths
are never expanded, so the icon comparison now returns null unless a fixed
target matches the icon exactly.

* test: drop redundant ok assertion before typed error guard

The testing guide asks for the typed error to be thrown before asserting a
successful Result value, and says a preceding .ok assertion adds no coverage.

* fix(windows): point out-of-range LinkInfo offsets at their field

A LinkInfo, VolumeID or CommonNetworkRelativeLink offset that points
past its structure was reported at base + offset. With an offset such
as 0xffffffff that position exceeds uint32, so the report failed its
schema and the service discarded the whole partial result.

Report such issues at the offending offset field instead, which keeps
every issue offset and coverage.failing_offset inside the file. Cover
each LinkInfo offset field in the parser tests and the
LocalBasePathOffset case through the stable filesystem service.

* fix(windows): require RFC 4122 variant before deriving Tracker UUID facts

A version nibble of 1 alone does not identify a version-1 UUID. Also require the clock_seq_hi_and_reserved top bits to be 10, so other GUID layouts keep their raw value and derive no MAC or timestamp.

* fix(windows): ignore DeviceNameOffset fields unless ValidDevice is set

MS-SHLLINK 2.3.2 says DeviceNameOffset and DeviceNameOffsetUnicode are
ignored when the ValidDevice flag is clear. parseNetwork read both
regardless, so garbage in those fields became device-name facts or
malformed_structure issues. Read the flags once and only read the device
name fields when ValidDevice is set.

* fix(windows): keep unsupported Tracker headers as raw data

Check TrackerDataBlock Length (0x58) and Version (0) before decoding.
A block with any other header is retained as raw bytes with a
malformed_structure issue, so it no longer yields MAC and timestamp
facts under complete coverage.

* fix(windows): compare shortcut icon paths by normalized location

Collapse "." and ".." segments and repeated separators in the icon
comparison as text only, never opening a path. ".." stops at the drive
or UNC share root, and \\?\ and \\.\ paths stay verbatim.

Join LocalBasePath with CommonPathSuffix as the target and use the bare
base only when the suffix is empty, as the network share branch does.

Read the selected shortcut with lstat and open only, so a rejected
symlink's destination is never resolved.

* fix(windows): keep the UNC share in the root after repeated separators

normalizePath took the host and the next split part as the UNC root, so
\\server\\share\..\app.exe kept an empty share and let .. remove the
real share. Drop empty parts before picking the root so paths on
different shares stay different.

* fix(cli): parse windows shortcut limits as decimals

The four inspect-windows-shortcut limit options now go through
cliDecimalField like the other inspection commands, so values such as
0x10 are rejected and cliDecimalArguments.test.ts passes.

* fix(native): reject linked parents of windows shortcuts

A parent directory symlink or junction pointing at a UNC share was
followed by the first lstat, since the network check reads only the
path text and the symlink rejection covers only the final component.
On Windows, lstat each ancestor from the drive root down and reject
the path at the first link, before anything follows it.

* docs(native): move Windows shortcut guide and add its feature spec

Move the Shell Link guide to docs/guides/native/windows-shortcut.md and
list it under Native binaries in the site navigation, keeping the
/windows-shortcut public route. Update README, translated README, CLI
page and authored skill links to the new physical path.

Add docs/specs/native/windows-shortcut/ with spec.md, plan.md and
tasks.md, as required by docs/development/documentation.md.

* fix(native): admit the windows shortcut parent walk

On Windows the ancestor link walk ran before the provider's resource
admission, so close() could finish while the walk kept calling lstat.
Run the walk inside the same admission as the read, and check the
caller's signal before each ancestor lstat.

* fix(native): walk the effective parents of windows shortcuts

The ancestor link walk checked every prefix of the path as written, so
C:\alias\..\real\a.lnk was refused when C:\alias is a directory link,
although Windows removes alias\.. before opening the file. Walk the
ancestors left after removing . and .. components, keeping the
caller's spelling, never climbing above an absolute root, and leaving
\\?\ paths as written since Windows does not normalize them.

* test(native): assert the linked parent as a structured fact

The parent link regression matched the phrase "junction, which" in the
refusal message, so a wording edit would fail it. Report the linked
ancestor as observed.linked_ancestor on the input issue and assert that
fact instead of the explanatory text.

* test(native): bound the shortcut close gate and release it in finally

Race the parent walk lstat acknowledgement against inspection settling
with awaitAcknowledgement, then release the gate and join the inspect
and close work in finally so a failure reports its cause instead of
waiting for the Vitest timeout.

* fix(native): walk Windows shortcut parents lazily

windowsAncestors built and kept every parent prefix before the first
lstat, so a path with thousands of components allocated memory
quadratic in its length. It now keeps only the normalized components
and yields each parent from a running prefix as the walk reaches it.

吴佳浩Albenandmorluto 25885b05c0 feat(v8): inspect V8 code cache containers and retained byte patterns (#8993)
* feat(v8): inspect V8 code cache containers and their retained byte patterns

Bytenode-compiled `.jsc` files — the V8 code cache container that `vm.Script`,
`vm.compileFunction` and bytenode 2.x write, and that Node single-executable applications
and Electron apps ship — had no format-native reader. `inspect_binary_layout` shows the
surrounding ELF/PE and `inspect_artifact` inventories the file, but neither decodes the V8
structures, so an agent could not tell which V8 line produced the file, could not learn the
container is metadata rather than source, and had nothing to point at a version-pinned
decompiler. Issue #8543.

`inspect_v8_code_cache` joins the format-native family with `inspect_python_pyc`,
`inspect_erlang_beam` and `inspect_kernel_module`: one explicit local file, bounded parsing,
no execution, no installation, no child process.

**The container is version-dependent, so the reader reports roles with confidence instead
of assuming an ABI.** All eight header words are reported with byte offset, observed value,
the role this reader believes the word has, and whether that role is `confirmed`,
`inferred`, or `unconfirmed`. Only three facts gate admission: the header size this reader
pins, the V8 code cache magic high half `0xc0de` (the low half is
`ExternalReferenceTable::kSize` and varies per build, so it is a build fingerprint rather
than a constant), and a declared payload length that reaches exactly the end of the file.

I derived the field semantics from the producer rather than assuming them, and two findings
changed the design:

- **The word V8 calls the source hash holds the source length on the measured producers.**
  A 54-code-unit source stored `54`, and sources with the same code-unit length but
  different content stored the same value, including a source whose UTF-8 length was 154.
  The reader reports it as `source_length` and the docs say that this name is what the
  measurement supports, not a claim about what another build stores there.
- **`vm.compileFunction` sets a high bit in that word.** The reader masks it out and reports
  the producer family as `script` or `compile_function`, so the source length stays correct
  for both producers.

Embedded strings are reported as **byte-pattern observations with absolute byte ranges**,
labelled as such in the field name and in the limitations. A reported sequence is not proof
V8 retained it as a string, and a missing literal is not proof it is absent.

**Fail-closed boundaries, all covered by tests:** an unknown magic is a typed
`unsupported_target` failure because the file is not a V8 code cache; a short header or a
payload-length disagreement is a typed `invalid_request` failure. Neither yields a partial
parse and neither records Evidence.

Non-goals are explicit in the tool description and the docs: the payload is serialized V8
heap data, not source; recovering logic needs a version-pinned View8-style decompiler that
this tool neither provides nor depends on.

Fixtures are generated from the running V8 instead of committing a version-pinned binary, so
the tests exercise the real producer and stay valid across Node upgrades.

- Semantic owner and earliest changed stage: format-native V8 code cache container decoding.
- CLI and MCP/tool-catalog contract: one new `artifact-provider` tool and one new
  `inspect-v8-code-cache` CLI command, registered in `TOOL_CONTRACTS`, the `artifact`
  language family, `TOOL_EFFECTS`, the capability declarations and services, and the
  capability inventory. `docs:check` passes, so the generated catalog agrees.
- Provider, bridge, target-format, or platform compatibility: no provider runs and no
  external tool is required, so the tool is available on every supported Node host.
- Evidence, artifact, provenance, or reconstruction contract: complete Evidence with the
  payload byte range as its location; no artifact format, reader, or reconstruction change.
- Generated metadata, package, or installation impact: catalog and document facts
  regenerated by the existing checks; no new dependency.

Expected effects:

- [x] Target content is returned as bounded structured facts.

- `src/v8/V8CodeCacheParser.test.ts` (13 cases): real-producer header facts, per-field role
  and confidence, source length for both producers, an observation's absolute offset
  verified against the file bytes, the limitation text, foreign magic, payload-length
  mismatch, short header, missing payload bytes, a different build constant still admitted,
  and the observation budget.
- `tests/boundary/mcp/v8CodeCacheMcp.test.ts` (4 cases): advertisement and annotations,
  header facts over MCP, relative-path rejection, unsupported magic, malformed container.
- `tests/acceptance/v8CodeCacheCli.test.ts` (4 cases): the public CLI, relative-path
  resolution, byte-range observations, and the typed failure.

- `npx vitest run src/contracts src/v8 src/application/v8CodeCache src/domain/v8` — 242 passed
- `npx vitest run tests/boundary/mcp/v8CodeCacheMcp.test.ts tests/acceptance/v8CodeCacheCli.test.ts tests/boundary/filesystem/productCatalog.test.ts tests/acceptance/tools/localToolContracts.test.ts` — 20 passed, 4 skipped
- `npx tsc --noEmit -p .` — exit 0
- `npm run build` — exit 0
- `npm run lint` — 0 errors
- `npm run knip` — exit 0
- `npm run docs:check` — exit 0
- `npx oxfmt --check src tests docs` — exit 0

Gap: the header table is measured on node v24.22.1 / V8 13.6.233.17-node.58 only. No other
V8 build is available here, so a different build's field order is untested; that is exactly
why only three facts gate admission and the remaining roles carry a confidence level rather
than being asserted.

Additive. No existing tool, schema, or behaviour changes. The reader never executes the
selected file, never launches a process, and never accesses the network; its audited effects
are `mutatesSession: true` only, matching the other static format readers.

* chore: retrigger title and readiness checks after the title was corrected

* fix(v8): bound the payload scan and use the repository path conventions

Review feedback from @greptile-apps on four points.

**Bound the synchronous payload scan.** The scan is one synchronous pass over the
payload, so the 512 MiB ceiling allowed a single request to hold the process for
several seconds. The ceiling is now 64 MiB, matching the pinned CPython pyc reader,
and the default is 32 MiB. The scan stays synchronous, like the BEAM and ELF note
readers in this family, but the budget that bounds it is no longer large enough to
matter. The new `max_file_bytes` ceiling and default are documented.

**Use the absolute-path schema.** `path` now uses `absoluteLocalPathStringSchema`
instead of `localPathStringSchema`, matching `inspect_erlang_beam`. A relative name
previously passed validation and was resolved against the server's working
directory, so `module.jsc` could select a different file than the caller meant. The
rejection is now at the schema boundary.

**State the extraction step.** The handoff in `docs/v8-code-cache.md` now says a
cache embedded in a single-executable application or an Electron app must be
extracted first, because this reader requires the magic at byte zero and returns
`unsupported_target` for the surrounding ELF/PE executable.

**Load only the owning contract group in tests.** Both tests now import
`V8_CODE_CACHE_TOOL_CONTRACTS` directly instead of resolving the tool through the
full catalog, so a focused test no longer constructs every other tool's schema.

21 cases pass across the parser, MCP boundary and CLI acceptance files; `tsc` 0;
`build` 0; `knip` 0; `docs:check` 0; `oxfmt --check` 0.

* fix(v8): select the tool contract by name in the focused tests

Reverts the catalog-position selection I added for a review suggestion. This
repository has a lint rule (`rea(no-positional-tool-contract)`) that forbids
selecting a tool contract by catalog order, and `toolContract("inspect_v8_code_cache")`
is how every neighbouring focused test selects one. The positional form I tried
introduced two lint errors, so the named form stays.

The review concern was that resolving through the full catalog constructs every
other tool's schema. That cost is real but it is the repository's chosen trade:
catalog ordering must never select an operation or schema, and `toolContract` is
the named accessor that enforces it.

* test(v8): cover the new tool in the absolute-path boundary test

Main added `tests/boundary/mcp/absoluteLocalPathTools.test.ts` after this branch
was opened. It enumerates every tool whose MCP `tools/list` schema must reject a
relative path, and `inspect_v8_code_cache` uses `absoluteLocalPathStringSchema`,
so the tool belongs in that list. Adding it keeps the enumerated field set complete
instead of leaving one absolute-path tool untested.

`tests/boundary/mcp` + v8 + contracts: 256 passing. `tsc` 0; `build` 0; `knip` 0;
`docs:check` 0; `npm run lint` 0 errors.

* perf(v8): read the payload by index instead of allocating per byte

`for (const [index, byte] of payload.entries())` allocates a two-element array for
every byte of the cache payload. On a 1 MiB payload that allocation dominated the
scan.

Measured with a real cache built from this parser, alternated so the two forms run
against the same input:

| payload | entries() | indexed reads |
| --- | --- | --- |
| 1 MiB | 15.5ms | 4.4ms |

That is 3.49x on the scan, and the gap widens on smaller payloads where the
allocation cost is a larger share (7.3x at 64 KiB in a synthetic run of the same
shape). The scan is the whole cost of `inspect_v8_code_cache` once the file is read,
so this is the tool's own hot loop.

Output is unchanged: the parser returns one retained string for the 64 KiB fixture,
and `src/v8` plus the CLI and MCP boundary files stay at 21 passing. `tsc` 0;
`build` 0; `npm run lint` 0 errors.

* fix(v8): admit only decimal tokens on the numeric CLI options

Main added `tests/boundary/cli/cliDecimalArguments.test.ts` after this branch was
opened. It enumerates every numeric CLI option and requires `0x10` and `1e3` to be
rejected, because plain `Number` coercion would read them as 16 and 1000. This
command's three options forwarded the domain fields unchanged, so the test failed on
them:

    inspect-v8-code-cache options.maxFileBytes: Parser.parse accepts 1e3
    inspect-v8-code-cache options.maxStrings: Parser.parse accepts 0x10
    inspect-v8-code-cache options.maxStrings: Parser.parse accepts 1e3
    inspect-v8-code-cache options.minStringBytes: Parser.parse accepts 0x10

`cliDecimalField` publishes the input view that parses the decimal token first and
then lets the domain field own bounds, defaults and help, which is what the other
numeric commands use.

`tests/boundary/cli/cliDecimalArguments.test.ts` now passes. `tsc` 0; `build` 0;
`npm run lint` 0 errors; `knip` 0; `docs:check` 0.

* fix(v8): recognize module caches, and advise from remaining headroom

Two review findings, each measured on Node 24.22.1 before changing anything.

**A module cache was reported as a script.** `vm.SourceTextModule.createCachedData()`
sets bit 30 of the source-length word, which the source-length mask `0x1fffffff` leaves
out, and the producer check only tested the function bit at bit 29:

| producer | source word |
| --- | --- |
| `vm.Script` | `0x00000013` for a 19-unit source |
| `vm.compileFunction` | `0x20000009` for a 9-unit source |
| `vm.SourceTextModule` | `0x40000013` for a 19-unit source |

So a real module cache was labelled `script`, and `vm.Script` rejects that container. The
producer enum gains `module` and the module bit is tested first; the source length is
unchanged because both flags sit outside the mask.

**The budget advice recommended a retry that could not work.** Both limits have
ceilings — `max_strings` at 65536 and `min_string_bytes` at 256 — so an admitted file
with more than 65536 runs of 256 bytes reached the branch while every suggested retry
was a rejected input. `observationBudgetRemediation` now reads the remaining headroom
and only recommends a change that is still admissible, falling back to selecting a
smaller artifact when neither can move. The parser message states the fact and leaves
recovery to the provider, which is the only place that can see both budgets.

`MAX_INSPECT_V8_CODE_CACHE_MIN_STRING_BYTES` names the `min_string_bytes` ceiling that
the schema previously spelled inline, so the advice and the schema cannot drift.

`docs/v8-code-cache.md` describes both flag bits. `src/v8` plus the CLI and MCP boundary
files: 28 passing; 7 new cases fail on the base commit. `tsc` 0; `build` 0;
`npm run lint` 0 errors; `knip` 0; `docs:check` 0.

* refactor(v8): decide the budget recovery as data, and test the decision

The remediation tests matched fragments of the advice sentence and banned old phrases.
`docs/testing.md` asks for error codes, recorded limits and recovery behaviour instead of
frozen prose, so a harmless reword could fail those tests while wrong advice passed them.

`observationBudgetRecovery` now returns the decision — which retries remain within the
schema's admitted range, and whether a smaller artifact is the only option — and
`observationBudgetRemediation` renders one sentence from it. The tests assert the
decision, so the wording is free to change and an incorrect choice cannot pass.

This also fixes a bug in the previous shape: it took the `min_string_bytes` branch to mean
"lower it", but that branch is reachable with the value already at the schema minimum,
where lowering is not a legal retry. The decision now carries `canLowerMinStringBytes`
and a `requiresSmallerArtifact` flag for that case.

5 cases, all failing on the base commit, covering both headroom states, either ceiling
alone, and the run-length floor. `src/v8` plus the CLI and MCP boundary files: 28
passing. `tsc` 0; `build` 0; `npm run lint` 0 errors; `knip` 0; `docs:check` 0.

* ci: rerun after the wakaru release download recovered

The only failing job on this branch was `javascript_recovery / real-javascript-recovery`,
which failed on `curl: (22) The requested URL returned error: 504` while downloading
`wakaru-linux-x64.tar.gz`. The release is reachable again (HTTP 200), so this empty
commit re-triggers the lane.

* docs(v8): place the guide in the tree and record the feature

The guide sat at `docs/v8-code-cache.md`, outside the `docs/guides/` tree every other
guide uses, and neither index linked it, so it could not be reached from
`docs/README.md` or the VitePress sidebar.

Moved to `docs/guides/javascript/`, linked from both indexes, and recorded the feature
under `docs/specs/v8-code-cache-inspection/` with `spec.md`, `plan.md` and `tasks.md`.
The spec keeps only the premises that were measured on Node 24.22.1 — the three producer
words and the retained-string layout — rather than restating the implementation.

`npm run docs:check` 0; `npm run format:check` 0; `tsc` 0; `build` 0; `lint` 0 errors;
`knip` 0. V8 reader, CLI and MCP files: 28 passing.

* docs(v8): use the documented spec path and test the advice against its struct

Two review findings.

**The records were at `docs/specs/v8-code-cache-inspection/`.** `AGENTS.md:73` asks for
`docs/specs/<domain>/<feature-slug>/`, so they move to
`docs/specs/v8/code-cache-inspection/`.

**The verification section claimed more than the tests do.** It said the producer cases
were built from real `vm.Script`, `vm.compileFunction` and `vm.SourceTextModule` output,
and that the budget advice was compared with its owning formatter. In fact only
`vm.Script` and `vm.compileFunction` are real producers — the module case sets the
measured bit on a `vm.Script` cache — and only `observationBudgetRecovery` was asserted.

Corrected the claim, and closed the second gap rather than only describing it:
`observationBudgetRemediation` now has four cases holding the sentence to the struct it
renders from. The sentence must not advise a knob the struct closed, and must mention a
smaller artifact exactly when the struct requires one. Verified by making the sentence
advise `max_strings` after the ceiling was reached — the test fails. Wording stays free;
wrong advice does not.

`npm run docs:check` 0; `npm run format:check` 0; `tsc` 0; `build` 0; `lint` 0 errors;
`knip` 0. V8 reader, CLI, MCP, absolute-path and decimal-argument files: 34 passing.

* fix(v8): restore the absolute-path contract entry after the rebase

The rebase onto `main` conflicted in `tests/boundary/mcp/absoluteLocalPathTools.test.ts`:
`main` gained `inspect_api_contract`, `inspect_devicetree`, `inspect_playwright_trace` and
`inspect_python_pyc` in both the contract list and the path-field map while this branch
added `inspect_v8_code_cache`. Both sides are additive, so both are kept.

Without the resolution the branch carried conflict markers, which made `mergeable_state`
`dirty` and every check on it meaningless. Re-verified after the rebase: `tsc` 0, `build` 0,
`format:check` 0, `lint` 0 errors, `knip` 0, `docs:check` 0, and the V8 reader plus its CLI,
MCP, absolute-path and decimal-argument boundary files at 34 passing.

* test(v8): pin the producer from the runtime's own header word

An independent reviewer ran these files on Node 22.23.4, 24.22.1 and 26.12.1. Only 22.23.4
failed, on `separates the compileFunction producer bit from the source length`, expecting
`compile_function` and reading `script`.

The cause is the fixture, not the parser: `vm.compileFunction(...).cachedData` carries
`0x20000009` in the source-length word on Node 24.22.1, with bit 29 set, while Node 22.23.4
does not set that bit at all. Whether a given V8 build marks the word is a build detail, so
asserting one build's spelling made the check version-dependent.

The case now reads the word the runtime produced and asserts the parser maps it correctly,
and keeps the part that must hold everywhere: the source length is the low bits, so it
equals both `word & 0x1fffffff` and the source's length. The flag meanings themselves stay
pinned by the synthetic `withHeaderWord` cases above, which do not depend on any build.

Reverting the parser's `compile_function` arm fails this case and
`keeps the function and module flags distinct`. `src/v8` plus the CLI, MCP and absolute-path
boundary files: 24 and 34 passing. `tsc` 0; `build` 0; `npm run format:check` 0;
`npm run lint` 0 errors; `knip` 0.

* fix(v8): report an unflagged producer word as unknown, not as a script

`vm.compileFunction` marks bit 29 of the source-length word on Node 24.22.1 (`0x20000004`
for a 4-unit source) and does not mark it on Node 22.23.4 (`0x00000004` for the same call).
Whether a V8 build marks a function cache is therefore a build detail, and an unflagged
word is either a `vm.Script` cache or an unmarked function cache. The container carries
nothing that separates the two.

The reader reported `script` for that case, which is a confident claim the bytes do not
support. My previous commit made the test accept whichever value the runtime produced,
which recorded the ambiguity instead of resolving it in the contract. `unknown` is now a
producer value, the unflagged word maps to it, and the observed word stays in
`header.fields` for a caller that trusts a specific build fingerprint. A limitation line
says the same in the report itself.

`header.producer` widens to `["script", "compile_function", "module", "unknown"]`; `script`
is no longer produced, because no unflagged word can be shown to be one.

The spec's producer rule and its verification notes are updated to match. Reverting the
mapping to `script` fails 2 of the 24 `src/v8` cases. `src/v8` with the CLI, MCP and
absolute-path boundary files: 33 passing. `tsc` 0; `build` 0; `docs:check` 0;
`npm run format:check` 0; `npm run lint` 0 errors. `knip` reports one unused export
(`builtinDataEffectMethod`) on `main` as well, so it is not from this change.

* fix(artifacts): retain completed identity across native parser failures

* docs(v8): preserve unknown unflagged cache provenance

* style: format reviewed source changes

* fix(docs): preserve routes and navigation cache inputs

* fix: repair the static-check failures on the default branch (#2895)

* fix: repair the static-check failures on the default branch

The default branch fails its own required `Static checks` job three ways, so
every pull request reports that job as failed regardless of its own change.

- `npm run format:check` reports `src/domain/functionComparison.test.ts` and
  `src/ida/IdaOperationRunner.ts`.
- `npm run lint` reports a duplicate `import { join } from "node:path"` in
  `tests/boundary/mcp/ghidraInventoryMcp.test.ts` (lines 4 and 17).
- `npm run typecheck` reports `format: "devin"` missing from the client format
  union in `src/application/SupportedClients.ts`, and an unchecked index in
  `tests/boundary/cli/clientProfileLifecycle.test.ts`, whose pair array is
  inferred as `string[][]`.

Apply the pinned formatter, drop the duplicate import, list the `"devin"` format
that its own definition already uses, and mark the pair array `as const`.

Validation: `npm run check:fast` and `npm run format:check` pass.
