feat(audit): report what a shipped app exposes to static analysis (#8525)
* feat(audit): report what a shipped app exposes to static analysis
Adds `audit_release_exposure` and `rea audit-release-exposure` to report
source maps, Electron fuse implications, extractable payloads, debug
information, build metadata, and credential markers. Checks carry stable
IDs, observations, statuses, and fixed remediation, while incomplete and
unassessed checks remain visible without implying a security verdict.
Credential findings include only rule IDs and locations. The CLI
supports `--fail_on` severity thresholds and exits 3 when an exposed
check meets the threshold.
* fix(audit): keep incomplete coverage unknown across text, fuses, Go flags and cancellation
Probe files with unrecognized names as text, keep undecided fuse slices
unknown, forward opaque container coverage, read paths from Go build flags,
and compare inventoried digests before accepting owner facts.
Keep typed cleanup failures and attach the partial report when a later owner
is cancelled. Pin the verifier's @electron/fuses version and move the tests
to the named contract family.
* fix(audit): match package members by source spelling and close remaining coverage gaps
Reopen package members by their source spelling and keep caller path
traversal in directory reads. Parse quoted and attached Go build flags, bind a
native image fuse read to its own digest, and keep reader resources and the
audit's partial report when cleanup or cancellation combine failures.
* fix(release-exposure): bind package members by ordinal and follow named map references
Package members were matched to container entries by sourcePath, which is
not unique in a PyInstaller executable, through a queue that only moved when
a member was reopened. Bind by container-relative path and duplicate ordinal,
the numbering inventory uses, so read order cannot change which bytes a
member gets.
A sourceMappingURL naming a file without a map extension was ignored. Local
targets are now examined as maps whatever their name, and a target already
scanned as plain text leaves coverage unknown.
* fix(release-exposure): match data: source map scheme case-insensitively
URL schemes are case-insensitive, so an inline declaration such as
//# sourceMappingURL=DATA:application/json;base64,... was routed to the
local-reference path, which ignores scheme URLs. Its embedded sources were
silently dropped and source_map_sources reported not_observed.
* fix(release-exposure): normalize declared map targets and count unreached ones
A sourceMappingURL that decodes to a decomposed name (cafe%CC%81.json)
never matched the inventoried member, whose logical path is NFC, so the
map was scanned as ordinary text and its sourcesContent went uncounted.
Map-target lookups now use an NFC key on both the record and lookup
side; the declared URL is left as written.
A declared map target that is never reached is now counted as a skipped
map, so the source-map checks read as unknown coverage instead of
not_observed.
* fix(release-exposure): recover indexed leaves after any map format failure
An indexed map whose one leaf has malformed mappings (such as AA) threw a
format failure that only recovered leaves for unsupported sections, so a
valid sibling leaf with sourcesContent was dropped and
javascript.source_map_sources read unknown instead of exposed. Leaves are
now recovered for any format failure, with the envelope parse guarded so
invalid JSON still falls through to the unparsed count.
A nested package that inventory recognized but did not expand was probed
as a plain binary and left the source-map checks at not_observed. It now
marks coverage unknown and records a limitation.
Reader tests assert the javascript.source_map_sources status for the NFC
map-name cases as well.
* fix(release-exposure): count an unexpanded nested package as a readable member
An unencrypted nested package that inventory recognized but did not
expand is still a member its parent package already read. Count it as
readable so packaging.extractable_payload reports exposed, while its
own contents keep coverage unknown.
* fix(release-exposure): bound the indexed leaf fallback by decoder limits
The fallback walk after a map format failure expanded every section and
built a full ancestor path per leaf, so a map refused for nesting depth
could still allocate far past the decoder budgets. Walk only to the
64-level section depth and the shared record budget, keeping leaf maps
without materializing section paths.
* fix(release-exposure): collect UNC roots from Go flag paths
A flag such as -I\\buildhost\sdk\include matched none of the path roots
in GO_FLAG_PATH, so a network path that was the only one in complete
build info left go.build_paths at not_observed. Accept \\host\share
roots alongside the slash-rooted, dot-relative and drive-letter forms.
* fix(release-exposure): keep Electron undecided without positive proof
The desktop owner names Electron only from an ASAR layout, so an asar: false
build has no candidate. A complete scan with no candidate was reported as
not_electron, which outranks unresolved and safe fuse outcomes and hid them
as not_applicable.
Leave the family unknown unless the fuse holder rules Electron out: an app
bundle with no Electron Framework, or a directory with complete coverage
whose native images were all read and hold no sentinel. A directory with no
native image is not proof, so its fuse checks now report unknown.
* fix(release-exposure): decode wide text members before scanning
A member's kind bypassed the NUL guard, so a UTF-16 plist was decoded as
UTF-8, matched nothing and still counted as scanned. A directory holding
only that member reported text.credential_markers as not_observed.
Decode by byte order mark at one boundary instead. UTF-16 is scanned in
either byte order, and inline maps read the same text. UTF-32 and NULs no
mark explains count as skipped, whatever the member's kind. A binary
plist keeps its raw scan. Unnamed members with a mark now reach the
scanner, and the plist decoder shares the same mark detection.
* fix(release-exposure): follow file: URL source map declarations
The scheme guard in noteLocalMapReference returned on every URL scheme, so
a declaration such as file:///release/debug.json was dropped with the remote
ones. A member without a .map name was then scanned as ordinary text and
javascript.source_map_sources reported not_observed.
Convert file: URLs with fileURLToPath and record them in mapTargets through
the same step as relative declarations. A target that is never reached, or
that was already scanned as text, counts as skipped, and so does a malformed
file: URL. A file: URL names one absolute location, so a .map target outside
the inventory stays unassessed rather than being trusted by its name. Remote
schemes stay ignored.
* fix(release-exposure): match backslash-relative Go flag paths
GO_FLAG_PATH accepted dot-relative roots only with a forward slash, so
`-I..\sdk\include` and `-I.\sdk` produced no path and go.build_paths came
back not_observed. Accept either separator after the dots.
The CLI acceptance test now expects unknown for electron.run_as_node on a
directory with no native images, matching the service.
* fix(release-exposure): keep fuses unknown on incomplete inventory
A directory inventory that stops at an acquisition limit never reports
the images it did not reach, so the native image sample has no omission
and safe fuses on an included helper settled to not_observed even though
scan coverage was unknown.
Treat unknown coverage like a truncated sample until the Electron
executable is accounted for. A selected native file is that executable,
so it keeps its decided fuse result.
* fix(release-exposure): decode binary plists before scanning
A binary plist stores each string as ASCII or UTF-16BE. Scanning the raw
bytes as UTF-8 missed any string the encoder kept in UTF-16, such as one
with a non-ASCII character, and still counted the member as fully
scanned, so text.credential_markers read not_observed.
Decode through the plist owner and scan its strings, dictionary keys and
data. A plist that cannot be decoded keeps its raw bytes in the scan and
counts as skipped, so coverage stays unknown.
* fix(release-exposure): keep UTF-8 members that hold a NUL
Any NUL in a member's first 512 bytes made the decoder give up, so a script
with a literal NUL in a string never reached the credential or inline-map
checks. An exposed marker in it read as unknown, and --fail_on high exited 0.
Validity alone cannot tell wide text from UTF-8, since ASCII in UTF-16 is
valid UTF-8. Treat a header that is an eighth or more NUL bytes as wide text
and anything not UTF-8 as undecoded, and scan the rest.
The docs now separate BOM-marked UTF-16, which is scanned, from wide text
with no byte order mark, which is not.
* fix(audit): scan every string a binary plist stores
The plist scan read only the decoded value, which drops objects the root no
longer references and entries a later duplicate key replaced. Those bytes
still ship, but the audit marked the scan complete, so a credential stored
there read as not observed and --fail_on high exited 0.
Read strings, keys and data from the object table instead. A stored object
that cannot be read leaves the member unassessed, and a total byte budget
bounds table entries that overlap to repeat the same text.
* fix(audit): keep packaged native images from ruling out Electron
The applicability check only looked at the "native images" omission. An
Electron executable inside a compressed .NET or PyInstaller member is recorded
under "packaged native images", so a directory whose on-disk hosts had no fuse
sentinel read as not Electron and all four fuse checks as not applicable.
Treat that omission as an unread image too.
* fix(audit): keep readable plist text when one object is unreadable
Throwing on one unreadable stored object discarded every string already
decoded, so a UTF-16BE credential beside a truncated unused object was lost:
the raw bytes that replaced it cannot match NUL-separated text.
Return the decoded text with complete false instead, and keep the raw bytes
in the scan beside it so ASCII in the unread object is still seen. The member
stays unassessed. Text past the budget ends the same way.
* fix(audit): read escaped inline maps and extensionless SEA entries
A data URL may percent-escape its base64 payload, so a map such as one padded
with %3D did not decode and the audit counted no embedded source map. Decode
the escapes before reading the base64.
A directory walk classed a SEA entry by its code path, so a main script whose
code path names no script was never scanned as JavaScript and its inline map
went unseen. Class it by the role the SEA metadata gives it.
* fix(audit): check plist text against the budget before decoding it
decodeBinaryPlistText decoded each stored object before comparing its size
with the remaining budget, and it keeps going after an object is rejected so
later text is still read. A plist under the input limit could repeat a large
range through overlapping table entries and force gigabytes of decoding that
the audit then discarded.
Separate finding a stored payload from decoding it, so a range past the
remaining budget is rejected without allocating its text. Earlier text and
the incomplete result stay as they were.
* fix(audit): count a packaged PE with an unread header as a native image
A package member whose PE signature lies beyond the 4 KiB probe recorded only
a PDB failure. The image was neither read nor listed under packaged native
images, so a directory whose on-disk hosts had no fuse sentinel read as not
Electron and all four fuse checks as not applicable.
Count it as a packaged native image, the omission that keeps the question
open, and keep probing it for text as before.
* fix(audit): keep cleanup-incomplete errors from composed readers
A desktop, fuse, Go or Rust failure became a string on that check, so an
error with unfinished cleanup lost its resources and live bindings while the
audit reported success, and the MCP handler does not close the service after
each request.
Treat unfinished cleanup like cancellation: stop the remaining owners and
return the error with the partial audit. When the owner attached its own
partial, keep the error and replace the partial, so cleanup stays attributed.
* fix(audit): keep safe fuses unknown past a packaged native image
The fuse check counted sampled-out images as possibly unread but not native
images inside a package. A complete directory scan with a safe-fuse image on
disk, no ASAR hint, and an unopened packaged image reported the four Electron
checks as not_observed, although the Electron executable could be that image.
The fuse check, the Go and Rust checks, and the Electron rule-out each decided
this for themselves and had drifted apart. Move the decision to one domain
predicate, nativeImagesMayBeUnread, and use it in all three. A hinted
executable that was read still settles the check.
* fix(audit): settle fuses only on an identified host, and read Bun and HTML maps
A retained helper set electron_executable_included because the rank marks
every .exe or extensionless sibling of resources/app.asar. With more than four
siblings, or an inventory that stopped early, safe fuses on a helper reported
not_observed while the host went unread. Rank stays a sampling hint. The check
now settles only on an executable named as the host, or when inventory was
complete and every executable that could be the host was sampled.
A Bun sourcemap region is named .bunmap, so its role was lost and a complete
audit reported no source maps. Carry the region role from the reader's metadata
into the member view, in the expanded and unexpanded paths, and treat it as a
JavaScript map so an unparsable region stays unresolved, not a debug companion.
An HTML member was scanned as text but its inline scripts were never checked
for source maps. The HTML owner now returns each body, the reader examines it
like a script file, and bodies past the owner's limit count as skipped.
* fix(audit): charge map reads to the count before opening the member
An oversized or unreadable .map returned before readSourceMap counted it, so
the allowance of 32 never ran out. An unexpanded .NET or PyInstaller package
could then decompress every listed map member, about 1 MiB each, up to the
4,096 entry cap.
The count bounds reads, so examineMap now reserves the slot before it opens the
member. A map past the count is skipped unopened, and a linker map past it is
still settled from its bounded prefix. An inline data: map is already in memory
and keeps its charge at the point it is parsed.
* fix(audit): examine scripts HTML loads whatever they are called
isJavaScriptMember knows a script by its suffix or an assigned kind, and the
reader dropped the script references the HTML owner parses. An extensionless
main loaded by <script src="main"> was scanned as ordinary text, so a complete
inventory reported javascript.source_map_sources not_observed with shipped
sources in its inline map.
The reader now resolves each JavaScript script reference against the page and
its base href, and a local target without a JavaScript name is examined as a
script when reached. A target read before its HTML file, never reached, or not
placeable on disk counts as a skipped map, so the check stays unknown.
* fix(audit): charge sibling map reads to the map count
Every generic .map beside a selected file got a full 1 MiB read and a
parse, with no cumulative bound, so the 4,096-entry listing allowed about
4 GiB of reading for one small selection.
Move the slot rule into chargeMapRead, which examineMap and sibling
classification now share. Past the count a sibling reads only the header:
a linker map is still identified, and one that may be a source map stays
a skipped companion.
* fix(audit): report cleanup failures raised by member reads
A close failure during an embedded-package probe, member read or inventory
reaches the shared read filter as an ordinary reader failure. The filter kept
only cancellation and integrity, so the member became a skipped read, inspect
succeeded, and the retained descriptor was reported nowhere. MCP does not close
the service after each request, so no caller saw it.
Propagate any failure that carries cleanup, whatever its reason, so it reaches
releaseExposureFailure and the audit reports its retained resources.
* fix(audit): charge unsuccessful text reads to the byte allowance
An oversized, undecodable, or failed text read left textBytes unchanged, so
every member got the full per-member budget and the cumulative allowance did
not bound what a package decompressed. Count the bytes member reads produce
and charge them whatever the read yields. An oversized file on disk still
costs only its probe.
* fix(audit): bound the paths kept for HTML script targets
A base href is copied into every script target it resolves, so a page under
the text member allowance could retain hundreds of megabytes of paths. Charge
each new target's resolved path to a byte allowance and leave targets past it
unassessed.
* fix(audit): keep examining a page loaded as a script as HTML
A script element naming an .html member promoted that member to a
script, and the text pass then chose one reading. The page's own script
elements were never read, so an inline map in it was lost and a shipped
sourcesContent went unreported.
Run the script reading and the HTML reading independently, and list the
script target allowance among the cases that leave source map coverage
undecided.
* fix(audit): detect credential markers that end in a hyphen
The Google, GitLab, and Slack rules allow a hyphen in the token but ended
on a word boundary, so a token ending in a hyphen at the rule's minimum
length was missed and the audit reported the check as not observed.
Open-ended rules now take the whole token, and the fixed-length Google
rule checks the full token alphabet after its last character.
* fix(audit): confirm FAT identity for probed package members
The package probe treated a decoded FAT table as a universal Mach-O. A
JVM class past the 4 KiB probe shares the FAT magic, so its truncated
prefix decoded as a table, the member counted as an unread native image,
and Electron could not be ruled out of a complete scan.
Pass the member's declared size to the sniff and take identity from
classifyFatContainerEvidence. A member with no usable size, or with
slices past the probe, stays counted as possibly native.
* fix(audit): admit binary plists in package member probes
A package member's probe judged text by its own NUL test, which accepted
byte order marks but not the binary plist signature decodeMemberText also
reads. A PyInstaller executable shipping a binary Localizable.strings was
rejected without a scan or a skipped count, so a UTF-16BE private key
marker inside it could report not_observed.
Name the encodings that explain their own NULs in one predicate, and move
the plist fixture builders to module scope.
* fix(audit): locate Go findings only in images that retain build paths
The exposed decision required non-empty paths, but the locations took
every image whose build info read. An image with no paths was named as a
source of the leak beside the one that had them.
One predicate now decides both.
* fix(audit): keep completed findings when member cleanup fails
A descriptor close failure aborts the member scan, and the scan's state
was dropped with it, so the caller got a typed cleanup failure and no
report. Source maps already counted and credential hits already collected
were lost.
The reader now hands the service what it assembled, with coverage unknown
and a limitation saying so, alongside the failure. The service runs that
scan through its existing stopped-audit path: no later owner runs, and the
report goes on the error as its partial observation.
* fix(audit): keep coverage unknown for nested ASARs in package hosts
A member of a PyInstaller or .NET host reaches the binary probe as a
plain file. An ASAR among them has a NUL-bearing header, so the probe
dropped it with no traversal and no omission, and source map checks could
read not_observed with complete coverage.
Ask the ASAR owner's signature probe, and record a match as a nested
package that was not expanded, as inventory-classified ones already are.
* fix(audit): let native format facts outrank member names
examineMember tried the name-based text and map routes first, so a PE an
owner identified inside an ASAR, named payload.json, was read as text.
Its CodeView path and the packaged-native omission were both lost, and
native.pdb_path read not_applicable.
Route an owner-established native format to the native probe first, and
count an encrypted one as a packaged native image for the same reason.
* fix(audit): report relative paths given to compiler path flags
go.build_paths only kept rooted paths, so retained build settings like
CGO_CFLAGS=-Iprivate-sdk read not_observed even though the setting names
a directory.
Take the relative argument of a C compiler path flag, attached or in the
next field. Scope this to compiler settings, because Go's own tools use
the same letters for non-paths such as -B gobuildid and -T 0x1000.
* test(javascript): expect retained text on SVG inline scripts
The SVG test from main predates this branch's inlineScripts text field,
so each side passed alone and only their merge failed.
* fix(audit): keep an unresolved Electron host's fuses unknown
fuseCheck decided from whatever outcomes the images reported, so a host
with no fuse answer read not_observed as soon as any other image in the
directory reported safe fuses.
Pass the images named as the host into the report and leave a check
unknown when one of them has no answer for it. Other images stay free to
have no fuses, because helpers in a real Electron install have none.
* fix(audit): bound the paths kept for local source map targets
noteMapTarget kept every declared target resolved against its member's
directory, so a short URL under a long directory could retain far more
than the script's own size, with no cumulative limit.
Add the allowance noteScriptTarget already has. A target past it stays
unassessed and counts as a skipped map, and is never read.
* fix(audit): borrow the audit's scope admission for inventory
inspect holds resources.run for the whole audit, and inventoryArtifact
entered the same scope again. With failed cleanup pending from another
audit, the inner run waits for a drain that waits for the outer run.
Add inventoryArtifactInScope, which takes the caller's admission.
* fix(audit): run the exposure verifier's commands under supervision
The verifier launched npm and the CLI with raw execFile and then removed
its temporary tree, so a timed-out child could outlive the tree it was
using.
Use the shared verifier commands and close them before removing the tree.
Their exit error carries stdout on its snapshot, so the audit's exit-code
branch reads it from there.
* fix(audit): read relative -L paths and split flag arguments
The relative-path reader handled C compiler settings only, so a directory
kept through Go's own linker flag, such as -ldflags='-L private-sdk -s -w',
reported go.build_paths as not_observed.
A quoted flag and argument also reached it as one field. The separating
space stayed on the argument, which reported rooted paths twice and kept a
leading space on relative ones.
Give -ldflags its own pattern that matches only -L, so -B gobuildid and
-T 0x1000 stay ignored, and consume the separator in the flag patterns.
* fix(audit): keep embedded leaves beside schema-invalid map fields
The reader recovers independent indexed leaves only after a
SourceMapFormatFailure, but inspectSourceMap let the schema's ZodError
through. A sibling with mappings "!", a section with a bad offset or a
root with a bad field skipped recovery, so a valid leaf with
sourcesContent reported javascript.source_map_sources as unknown.
Normalize schema rejection in SourceMapFormat, which owns these parses,
so every structural failure reaches consumers as a format failure. The
message is unchanged, and the codec and web fetcher already map both
cases to the same result.
* fix(audit): keep packaged executables' own packages unknown
examinePackagedBinary counted a native image inside a package and moved
on, while only on-disk images reached the embedded-package probes. An
ASAR carrying a PyInstaller, Bun, Node SEA or .NET executable with a
source map therefore scanned complete and reported
javascript.source_map_sources as not_observed.
Run the same classifier on packaged images. The probes read carrier
offsets from a file, so the member's bytes stay in a temporary file for
the probe alone. A detected package keeps member coverage unknown, as a
nested ASAR does, and an image past one file's total byte allowance
stays unprobed and unknown. A plain native member leaves coverage intact.
* fix(audit): read an app's sampled images for fuses
A .app target sent only the bundle candidate to the fuse reader, which
resolves to the outer Electron Framework. A sidecar with RunAsNode enabled
was never read, so the check reported not_observed in the app view while
the directory view reported exposed.
Send the bundle candidate first and then the sampled native images. An
image whose digest matches the bundle's read is skipped, so the framework
is not read twice. A sidecar's safe fuses cannot settle the outer framework,
so a bundle read with no answer for a fuse keeps that check unknown.
* fix(audit): read a Node shebang as script identity
The path classifier gives an extensionless executable a resource kind,
so a script such as bin/runner with a `#!/usr/bin/env node` header was
scanned as text without its inline maps being examined or counted. A
complete inventory then reported no shipped sources for it.
The probe holds the first bytes a member reader sees, so establish the
identity there. The script keeps the usual outcomes: a map that is read
counts, and one past an allowance or undecodable stays unknown.
* fix(audit): keep linker strings out of Go build paths
Reading `-X 'main.usage=-L level'` as a library directory made
go.build_paths report `level`, so a plain string could fail an audit
under --fail_on low.
Read the optional package selector once, before the setting's first
flag, and keep the argument of -X attached to it, so a string it sets
is never scanned as another option.
* fix(audit): keep a failed probe directory removal owned
A packaged image's probe copies the member's full bytes into a temporary
directory. When removing it failed, the error became an ordinary
unreadable probe: the audit could still succeed, nothing could retry the
removal, and the client heard nothing about the leftover bytes.
Hold the directory in the reader's resource scope, so close retries it,
and report the unfinished cleanup without replacing a primary failure.
* fix(audit): keep a declared .map from reading as a linker map
A script's sourceMappingURL=assets.map was dropped because the name
already looked like a map. A malformed assets.map then settled as a
linker map, so both source-map checks read not_observed and
native.debug_companions reported an exposure the release does not ship.
Keep a generic .map name as a declared target and read it as a
JavaScript map, in either scan order, so it stays unresolved.
* test(audit): rethrow typed errors from release exposure checks
A failed Result was rewrapped in a plain Error, which dropped its type,
cause and cleanup details from the test output.
* fix(audit): match companions by member identity, not spelling
An ASAR member's location is relative, and a declared map target is
absolute, so a malformed assets.map read before z.js stayed a linker
companion. The examined-map lookup, which is normalized, then returned
early, leaving both source-map checks not_observed.
Index companions by memberLocationKey and keep each reported spelling
under it. Spellings stay distinct because symlinks can make them differ.
* fix(audit): retract only guessed linker maps on a declaration
A script declaring sourceMappingURL=symbols.pdb after the scan reached
symbols.pdb removed the shipped PDB from the companion list, because a
late declaration retracted any companion. native.debug_companions could
then read not_observed.
Keep name-identified companions in their own set, and retract only maps
that were read as non-JSON and guessed to be linker maps.
* fix(audit): record an unfollowed map link as skipped
The directory and ASAR readers do not follow links, so a symlinked
app.js.map dropped out before any map counter moved. Its target was
scanned as plain text, and both source-map checks read not_observed.
Count a link that names a map as skipped wherever entries reach the
audit, and mark it examined so a declaration does not count it twice.
* fix(audit): read relative paths in Go compiler and assembler flags
A binary built with -gcflags=-I private-sdk keeps that setting, but
relative parsing covered only C compiler settings and -ldflags, so the
directory dropped out of go.build_paths.
Give -gcflags and -asmflags their own path options, taken from what
go tool compile and go tool asm document, and strip the package selector
as -ldflags does. The assembler's -D defines a symbol, so it is not one.
* docs(audit): state the packaged image read allowance
Packaged ELF, Mach-O and PE images are read in full and copied to a
temporary file, sharing one max_file_bytes allowance, but the docs and
coverage.allowances still said only a PE gets more than a header read.
Name the allowance and the copies in docs/release-exposure.md,
RELEASE_EXPOSURE_ALLOWANCES and the max_file_bytes description.
* docs(audit): say how go.build_paths treats rooted -X values
A rooted -X value cannot be told from a file path, so the audit reports
it. State that, and why, so the rule is a contract rather than a side
effect of how flags are scanned.
* fix(audit): keep a declared sibling map out of the linker guess
When the selected file declared a sibling map, the sibling classifier
never consulted the declaration. A malformed assets.map then read as a
linker map and raised native.debug_companions.
Leave a declared sibling to the unreached-target accounting, as members
already are, so it stays an unresolved source map.
* fix(audit): keep undecodable Go and Rust metadata unknown
Unsupported meant two things: a container this reader does not handle,
and metadata the image holds in a form the reader cannot decode, such as
a compressed .dep-v0 section. Both read as not_applicable, so an image
that carries metadata reported that the check did not apply.
Mark the second case on the format failure and carry it on
AnalysisUnsupportedTargetError, so the audit records a failed read and
stays unknown. The tools' own errors and messages do not change.
* fix(audit): keep coverage unknown for a PE header past the probe
A packaged member whose PE signature lies beyond the probe prefix stayed
unclassified, so the embedded-package probe never ran and coverage stayed
complete. A map inside such an image then read as not_observed.
Record the member as an unexamined package where it is already marked as
a possible native image.
* fix(audit): read the scripts of a standalone SVG
An SVG can carry a script with an inline source map, but only .html and
.htm members reached the script owner, so such a file left every map
counter at zero and javascript.source_map_sources read not_observed.
Treat .svg as a script-bearing page. htmlArtifactReferences already
reads SVG script elements, so this adds no parsing.
* fix(audit): keep every possible host when no name picks one out
With no named Electron host, every sibling ranks alike and
electron_host_paths stayed empty, so one image's safe fuses settled the
checks even when another possible host reported none.
Keep all sampled candidates as hosts in that case, so a candidate
without fuses leaves the checks unknown.
* fix(audit): read a text-named native member by its bytes
A PE member called payload.json took the text route, so it reached no
native probe, and its CodeView path and packaged-native uncertainty were
lost.
Decide from the bytes the text read already loaded, so real text costs
no extra read and the map and text allowances stay as they were.
* fix(audit): let a map or script read identify a native member
A package lists names without formats, so a PE called payload.js.map
took the map route and never reached a native probe. Its CodeView path
was lost, and with nothing counted as failed, native.pdb_path could read
not_applicable. A PE at a declared script or map target was lost the same
way, because declaration overrode the route.
Decide from the bytes the route already read, in the map route as in the
text route, and keep the listed kind for a promoted script target. Real
text and maps cost no extra read, so those allowances are unchanged.
* fix(audit): name a symlinked sibling debug companion
Selecting an executable skipped every symlink beside it before the name
check, so an app.pdb link left no companion path and no skip count, and
native.debug_companions read not_observed. Selecting the directory
reports the same link.
Check the name first. The map branch already needs a regular file, so no
link is followed.
* fix(audit): keep map coverage unknown for a linked script
A link named app.js to an extensionless payload was skipped as a link,
and its target was read as plain text with no map directives parsed. An
inline map there left no parsed or skipped count, so
javascript.source_map_sources read not_observed. Only links with a map
name were counted.
Count a link under any name that can declare a map, the set an unread
member already uses. It stays one omission when a page or a directive
also names it. The target is still not followed.
* fix(audit): keep a declared JavaScript map beside a selected file unknown
A local sourceMappingURL with a JavaScript map name such as app.js.map
was dropped on the assumption that it would be examined as a member.
When the selection is a file, sibling .js.map files are never read, so
the declared map left javascript.source_map_sources not_observed while
the same target spelled as a file: URL left it unknown. Record every
local target so an unreached one counts as skipped.
* fix(audit): read paths a C compiler forwards to the linker
CGO flags can hand linker options through -Wl,a,b or -Xlinker a. The
compiler flag parser saw -Wl,-L,private-sdk as one field and missed the
relative library directory, so go.build_paths reported not_observed.
Split forwarded options out before reading paths and read them with the
linker's own path options (-L, -T, --library-path, --script). This also
stops -Xlinker -Bsymbolic from being read as the compiler's -B prefix.
* fix(audit): read forwarded linker options by their linker meaning
The forwarded linker flag pattern read -Ttext=0x400000 as a script path
named text=0x400000, and it ignored -I, so -Xlinker -Ilib/ld-custom.so
lost the interpreter path the compiler flag pattern found before the
split.
Exclude the -T section and segment address options (bss, data, text,
text-segment, rodata-segment, ldata-segment) and read -I and
--dynamic-linker as paths.
* fix(audit): split Go flags as Go does and read external linker flags
Go splits a flag value with quoted.Split: a field that starts with a
quote runs to the matching quote, and any other quote is a literal
character. The reader stripped every quote, so CGO_CFLAGS
-I"/home/O'Neil/include" reported /home/ONeil/include, while cc was
given the directory "/home/O'Neil/include", quotes included.
-ldflags kept -extldflags values with the Go linker flags, where only
-L counts, so -extldflags=-Lprivate-sdk reported no path. The values
are now read as the C compiler driver reads them, including -Wl, and
-Xlinker forwarding.
A package member named payload.json or payload.js.map that holds an
ASAR took the text or map route, which checked only native signatures,
so the nested archive was scanned as text and coverage read complete.
The route's own read now recognizes the ASAR signature as well, and the
nested package leaves coverage unknown.
* fix(audit): keep a named script beside a selected HTML file unknown
A script element whose target had a JavaScript name such as app.js was
dropped on the assumption that it would be examined as a member. When
the selection is an HTML file, sibling scripts are never read, so a
sibling holding an inline map left javascript.source_map_sources
not_observed while the same target named app left it unknown. Record
every local script target so an unreached one counts as skipped.
* fix(audit): read a retained -pgo setting as one profile path
`-pgo file` names a single profile, and under -trimpath Go keeps only
its file name, so the flag readers dropped values such as
`private-training.pgo` and split paths with spaces or commas. Report
the value whole, skipping `auto` and `off`.
* fix(audit): read -extldflags paths as the external linker splits them
With -ldflags set to -extldflags '-L "/srv/private sdk"', the outer
flag reader could not match the path behind the inner quote, and the
external reader kept only relative paths, so go.build_paths read
not_observed. Read each -extldflags value once, as go tool link splits
it with quoted.Split, and collect rooted and relative paths from those
same arguments. The rest of the setting is read as before.
* fix(audit): read the Go linker's other path options
go.build_paths read only -L as a Go linker path option, so a retained
-ldflags='-tmpdir=private-obj -s -w' reported no path and --fail_on low
missed the directory.
Read every option `go tool link -h` documents as taking a directory,
path or file: -I, -L, -benchmarkprofile, -capturehostobjs, -cpuprofile,
-fipso, -importcfg, -memprofile, -o, -r and -tmpdir. -extld, -extar and
-libgcc name a program or `none`, so only their rooted values count.
* fix(audit): keep a quoted Go argument whole
goFields already reads -L "/tmp/private - sdk" as two arguments, but
each field was then split again before every whitespace-led dash, so
go.build_paths reported /tmp/private instead of the retained directory.
Split again only a field that begins with a flag, after any package
selector, as a quoted "-L dir -s -w" does. Any other field is one
argument and is kept whole, in -ldflags, -extldflags and CGO flags.
* fix(audit): keep coverage unknown for an unread packaged image
When a listed package member is a native image but its first read
fails, examinePackagedBinary returned before probePackagedImage could
mark its possible embedded package unexamined. Coverage stayed complete
and javascript.source_map_sources could report not_observed for a
payload nobody read.
Mark member coverage unknown wherever a native member goes unread,
including an encrypted one, as an image the probe could not read
already does, and say so in the limitations.
* fix(audit): read rooted Go tool path arguments whole
`-L "/tmp/private,sdk"` and `-L=/tmp/a=b` name one directory, so a `,` or
`=` in a documented path flag's argument is literal. `-trimpath` keeps its
prefix=replacement structure.
* fix(audit): count an unread packaged member once
* fix(audit): keep trimpath rewrites and directory fields apart from selectors
* fix(audit): keep a .map unsettled once a declaration was discarded
* fix(audit): skip env option arguments when reading a Node shebang
* fix(audit): keep companion coverage unresolved for a generic .map link
* fix(audit): count a dropped linker-map guess as a skipped companion
* fix(audit): read env settings after -- in a Node shebang
* fix(audit): route a selected native image named .map by its format
A directly selected or listed native image has no package format, so
examineMember skipped its native-first branch and sent a file such as
release.map through map routing. Its bytes then became a linker-map
guess and marked native.debug_companions exposed. Native format now
outranks the name for every member, packaged or not.
* fix(audit): read forwarded -rpath and -rpath-link as linker paths
A cgo build with CGO_LDFLAGS=-Wl,-rpath,private-runtime kept the
relative directory, but the forwarded linker parser only knew -L, -T,
-I, --library-path, --dynamic-linker and --script, so go.build_paths
reported not_observed. Add -rpath and -rpath-link to the same parser,
in the attached, = and next-field forms. Loader-expanded values such as
$ORIGIN/../lib and @loader_path/Frameworks name no build-host directory
and stay unreported.
* fix(audit): read each entry of a forwarded linker search list
-rpath and -rpath-link take a colon-separated search list. The loader
token filter tested the whole list, so -Wl,-rpath,$ORIGIN:/opt/private-runtime
dropped /opt/private-runtime along with $ORIGIN, and the rooted-path pass
cannot see an entry that follows a colon. Split each search list into its
entries and drop only the loader-expanded ones.
* fix(audit): expand loader tokens only in a linker search list
The runtime loader expands $ORIGIN and @loader_path only in a -rpath or
-rpath-link search list. The token filter also ran on the argument of -T,
-L and -I, so -Wl,-T,$ORIGIN.ld dropped a literal linker script path and
a complete read could report go.build_paths as not observed. Search list
entries keep the filter; every other linker path argument is kept as is.
* fix(audit): count a .map link beside a selected file as a skipped companion
The sibling scan skipped any .map entry that was not a regular file, so a
symlink such as symbols.map -> payload beside a selected executable left
debug companion coverage at not observed. The reader never follows links,
so the linker map such a link may name is unread, not absent. Count a
generic .map sibling link as a skipped companion without following it,
as noteUnfollowedMapLink already does inside a selected directory.
* fix(audit): split a linker search list only for an ELF image
Only the ELF linker reads a -rpath or -rpath-link argument as a
colon-separated list. The Mach-O linker stores each -rpath argument as one
directory, so -Wl,-rpath,@loader_path/lib:extra is a single loader-relative
entry, yet it was split and extra was reported as a build path. Carry the
native image format into the Go flag reader and split search lists only for
ELF; other formats read the whole argument as one entry.
* fix(audit): expand only the image loader's runtime tokens
A runtime search path token is expanded only by the loader of the image's
format. The ELF loader expands $ORIGIN, $LIB and $PLATFORM; dyld expands
@executable_path, @loader_path and @rpath. Each is literal text to the
other loader, so -Wl,-rpath,$ORIGIN:/opt/private-runtime on a Mach-O image
names a literal directory, yet it was dropped and go.build_paths reported
not_observed. Pick the token set from the native image format; the PE
loader reads no search list, so it expands none.
* fix(audit): keep a declared .map link beside a selected script a source map
The sibling scan counted any .map symlink as a skipped debug companion
before checking whether the selected script declared it as its source
map. classifySiblingMap already excludes a declared target that is a
regular file, so a declared symbols.map link added a false unknown to
debug_companions. Apply the declared-target check before either file-type
branch; noteUnreachedTargets still counts the unread map as skipped.
* fix(audit): byte-check members whose kind is only an inventory path role
Inventory gives a packaged member a role from its name, such as resource
for payload.json or source-map for payload.map. The packaged-format guard
treated any kind other than "file" as owner-stated, so a nested ASAR an
ASAR lists under one of those names skipped signature recognition and
cleared coverage. Track whether the package owner stated the kind (Bun
sourcemap region, SEA main script) and only skip the byte check then.
* fix(audit): read Go's linker -r setting as a runtime search list
go tool link -r sets the ELF dynamic linker search path, dir1:dir2:...,
which the linker writes to RUNPATH. It was read as one whole path, so a
release built with -ldflags='-r=$ORIGIN/../lib' reported the
loader-relative entry as a build path and go.build_paths as exposed.
Read -r entry by entry with the same image-loader-aware split and token
filter a forwarded -rpath uses: ELF splits at ':' and drops $ORIGIN
entries; Mach-O keeps the argument as one directory.
* fix(audit): keep a selected package executable's native carrier format
A directly selected PyInstaller executable named release.map recorded the
package format as its member format, even though its ELF or PE carrier was
already recognized. examineMember then missed the native-first branch and
treated the executable as a linker map, reporting a debug companion.
Forward the native carrier format for the selected file, as listed members
already do.
* fix(audit): keep coverage unknown for an unread unclassified member
A packaged member with no format of its own, such as a PyInstaller
payload.bin, recorded only a skipped text member when its read failed
before the header. Member coverage then stayed complete, though the
member could be a native image or carry a nested package. Leave
coverage unknown and say which member could not be read, as an unread
native member already does.
* fix(audit): keep ASAR header admission distinct from max_file_bytes
A directory holding an ASAR whose header exceeds the header admission
was reported as a file-size refusal with max_file_bytes advice, which
cannot fix it. Report the header admission as its own bound instead.
* fix(audit): thread the shared ASAR header admission into release exposure
createReleaseExposureService built ReleaseExposureReader with no admission,
so its inventory and every reopened ASAR reader stayed on the 16 MiB
default and ignored REA_ASAR_MAX_HEADER_BYTES and asar.max_header_bytes.
Resolve the admission in the composition with runtimeAsarHeaderAdmission,
as the Electron and V8 observation providers do, and pass it to both
inventoryArtifactInScope calls, the reopened container readers, and the
nested ASAR signature probe. The refusal now names the setting that can
raise it instead of claiming there is no runtime override.
* fix(audit): keep a nested ASAR probe stopped at the admission undecided
The release exposure reader treated an ASAR signature probe that stopped
at the header admission as "not an ASAR". A packaged member such as
payload.json holding an ASAR whose JSON starts past asar.max_header_bytes
was then read as plain text, its inner maps went unread, and
javascript.source_map_sources could stay not_observed.
A probe that reaches the admission limit, or runs out of a prefix read
after its extents parse, now marks package coverage unknown and records
a limitation, while the member is still examined as text.
* fix(cli): parse audit-release-exposure --max-file-bytes as a decimal token
Main now requires every numeric CLI option to admit decimal tokens and
reject 0x10 and 1e3 (tests/boundary/cli/cliDecimalArguments.test.ts).
Wrap the release exposure maxFileBytes option in cliDecimalField like the
other maxFileBytes options, so the domain field keeps its bounds and default.
* docs(specs): add the release exposure audit specification
Add spec.md, plan.md and tasks.md under docs/specs/artifacts/release-exposure/
as docs/development/documentation.md requires for a new feature, and list
them in docs/specs/README.md. The existing guide at docs/release-exposure.md
keeps describing current behavior and its route is unchanged.
* fix(audit): bind unpacked ASAR member reads to their inventoried digests
A selected ASAR is captured and checked against its inventoried digest, which
binds packed members. An unpacked member is read from its .unpacked companion
on disk instead, and readContainerMember and readEntryBytes never compared
those bytes with the member digest inventory recorded, so a companion
replaced between inventory and the scan was accepted.
readContainerMember now passes the member's inventoried digest for unpacked
entries, and readStreamBounded hashes the full stream, draining past the read
allowance when needed, and fails with "ASAR member changed before
interpretation", which surfaces as an artifact_changed error like the
container check. A regression test replaces a companion after inventory. The
guide, spec, plan and tasks describe the binding.
* fix(audit): let stated JavaScript roles outrank a .map name
isDeclaredMap() routed any member whose name ended in .map to map
handling before the owner's stated role or a page's script declaration
was considered. A Node SEA main script at boot.map, which the SEA reader
marks as javascript, and a .map script an HTML file loads both became
linker-map guesses, so their inline maps were never read and
native.debug_companions was reported exposed.
An owner-stated source-map role or a declared map target still makes a
member a map. Otherwise a stated javascript kind or a script target now
wins, and only then does the .map suffix, or the inventory path role that
repeats it, decide. Regression tests cover both cases, and the guide
notes that a SEA main script is read as a script whatever it is called.
* fix(audit): keep coverage unknown when a packaged text member fails to read
A compressed member named as text, such as payload.json in an unexpanded
PyInstaller host, can fail inflation before any header is returned. The
.bin case already leaves member coverage unknown because an unread header
may hide a nested image or package, but examineTextMember() only counted
the member as skipped text, so otherwise complete coverage stayed
complete and package-dependent checks could settle.
An unread packaged member whose kind its package did not state now goes
through noteUnreadBinary(), which counts it as skipped text, marks
coverage unknown, and records the limitation. A regression test corrupts
the zlib stream of payload.json in a CArchive host and checks the intact
member keeps coverage complete. The guide describes the rule.
* fix(audit): keep the unpacked ASAR digest check inside the read allowance
ea87cf8 made readStreamBounded hash an unpacked ASAR companion to its end
so it could compare against the inventoried digest, which drained the
stream past the read allowance. A 1 GiB unpacked module was read in full
for a 4 KiB header probe and again for a package probe, and a companion
that grew after inventory had no byte limit on that path.
readStreamBounded now stops at the allowance as every other member read
does, and compares the digest only when the member ended within the
allowance. A companion past the allowance stays over_allowance without a
digest verification. A test counts the bytes each scan read pulls from an
8 MiB companion. The guide and spec state the bound.
* fix(audit): read a script target whose bytes are a source map as a map

feat(artifacts): inventory NTFS $MFT record headers offline
An acquired $MFT stream had no reader, so an analyst holding one could only
treat it as an opaque file. Recognize the FILE signature of the first record
and inventory every record's header: sequence number, flags, used and total
bytes, base record reference and update-sequence array.
Each record's update-sequence fixups are verified against its sector
trailers. A mismatch keeps the header facts, is reported on the record and is
counted in the metadata, so a record that was not cleanly written is visible
rather than silently accepted. A missing or short array is reported as
unverified, a wrong signature stops the scan at its offset, and a trailing
partial record is reported as a byte count. Attributes, filenames and the
$UsnJrnl:$J journal are not decoded, so no path or change history is claimed.

feat(native): list ELF and Mach-O initializer and finalizer functions (#9574)
* feat(native): list ELF and Mach-O initializer and finalizer functions inspect_native_initializers and inspect-native-initializers list the functions an ELF or Mach-O image runs before and after main: ELF DT_INIT, DT_FINI, preinit, init and fini arrays and .ctors/.dtors, and Mach-O __mod_init_func, __mod_term_func and __init_offsets, with slot addresses, resolved targets, symbols where available and relocation facts for relocatable objects. Nothing is executed. Slot, symbol, relocation and note budgets are shared across tables, sentinels are matched at the image width, and target-derived names are bounded and marked untrusted. * fix(native): keep ELF initializer slots unresolved when relocation coverage is partial A skipped, unreadable or over-budget section relocation table now keeps every slot it could reach unresolved instead of reading the stored word as raw or dropping a .ctors slot as a sentinel. Dynamic writes that only partly overlap a slot, or write it twice, leave it unresolved. Linked images no longer reapply retained non-SHF_ALLOC link-time records. The dynamic relocation walk now pauses at the shared reader's step boundaries and observes cancellation there, resolved targets need only their first byte mapped, and unreadable symbol names make the report incomplete. * fix(native): stop reporting unchecked Mach-O initializer words as resolved Object files now apply their own section relocations: an UNSIGNED entry against a defined symbol gives symbol_addend, one against an undefined symbol gives unresolved_import, and any other entry leaves the slot unresolved. Linked images without a fixup decoder, such as 32-bit ones, keep pointer slots unresolved when an LC_DYLD_INFO bind stream or LC_DYSYMTAB external relocations could replace the stored word. LC_DYLD_INFO rebases now report dyld_info_rebase instead of chained_fixup, and unreadable symbol names make the report incomplete. Section headers keep their declared reloff and nreloc for this. * docs(native): move initializer 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 /native-initializers route is unchanged. The guide and spec also describe per-slot relocation coverage, retained link-time records, Mach-O object relocations, undecoded bind streams, the dyld_info_rebase resolution and unreadable names. * fix(native): keep IFUNC and partly relocated ELF initializer slots unresolved An absolute relocation against an STT_GNU_IFUNC symbol no longer reports the resolver address as the target. Section relocation records now use their real write width, so a record that writes only part of a slot, starts inside it or repeats it leaves the slot unresolved instead of reading a raw zero or dropping a .ctors slot as a sentinel. On 32-bit ARM the Thumb bit is cleared when locating a target's section and file offset, while value_va keeps the stored callable value. * fix(native): locate Thumb Mach-O initializer targets and reject arm64_32 with a 64-bit header On CPU_TYPE_ARM the Thumb bit is cleared when locating and naming a target, since nlist values do not carry it. An arm64_32 image that declares a 64-bit header is rejected as malformed rather than read with 8-byte slots. The guide and spec describe IFUNC relocations, partly relocated section slots, Thumb targets and this rejection. * fix(native): index initializer address lookups and keep ambiguous mappings unknown ELF and Mach-O initializer lookups now build the shared file mapping index once per image, so each slot and target lookup is logarithmic in the number of load segments rather than a scan of every mapping. An address that load segments map ambiguously no longer falls back to a section header offset. Its file offset is reported as unknown and the report is incomplete; only genuinely unmapped spans use the section fallback. * fix(native): report Mach-O bind names over the name budget A bound import name longer than the 1024-byte name budget was dropped without a trace, although it is the only identity of an unresolved initializer target. It now counts toward the over-long name limitation and makes the report incomplete. * test(native): count mapping lookups instead of timing the load index regression The load-mapping regression asserted a wall-clock bound, which is sensitive to machine load. It now spies on the shared mapping module and requires the same number of mapping scans and index builds for 8 and 64 slots, so a per-slot scan of every load segment fails deterministically on a small fixture. * fix(native): yield while decoding legacy rebase runs * fix(native): preserve initializer mapping and coverage * fix(native): index legacy fixup spans * fix(native): preserve relocation uncertainty and bound bind lookup work * fix(native): validate ELF slot mappings and yield section relocation scans --------- Co-authored-by: Matt Van Horn <455140+mvanhorn@users.noreply.github.com> Co-authored-by: morluto <76467478+morluto@users.noreply.github.com> |

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. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01KuWHGvzJkrhCqjtEHUwqyH * 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 --------- Co-authored-by: Matt Van Horn <455140+mvanhorn@users.noreply.github.com> Co-authored-by: Claude Opus 5.5 <noreply@anthropic.com> Co-authored-by: morluto <76467478+morluto@users.noreply.github.com> |

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 --------- Co-authored-by: Matt Van Horn <455140+mvanhorn@users.noreply.github.com> Co-authored-by: morluto <76467478+morluto@users.noreply.github.com> |

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 --------- Co-authored-by: Matt Van Horn <455140+mvanhorn@users.noreply.github.com> Co-authored-by: morluto <76467478+morluto@users.noreply.github.com> |

docs: organize canonical documentation layout and verify new pages (#2791)
* docs: organize canonical documentation layout (URGENTE) Group all existing authored guides by domain and ownership, expose complete navigation, and preserve their public routes. Update physical path consumers and release configuration while retaining historical records. Document domain-based specs and ADR slugs without global numbering. Co-Authored-By: Codex <noreply@openai.com> * fix(docs): honor home layout in all-page route verification * 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. * fix(setup): keep Devin on the JSON configuration dialect --------- Co-authored-by: 吴佳浩 <wujiahao@supremind.com> Co-authored-by: morluto <76467478+morluto@users.noreply.github.com> * fix(docs): update links after guide relocation * docs: correct verified documentation route counts * fix(docs): update browser capture guide link after move (#2820) Refresh gettext protected-link comments alongside the authored href.
