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

* 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.

* 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
