* 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.

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>

Deno compile executables
inspect-artifact inventories a deno compile executable. extract-artifact writes the embedded virtual files through the existing safe output tree. Neither operation runs the executable or the Deno runtime.
rea inspect-artifact ./app --json
rea extract-artifact ./app --json
In MCP, open the executable with open_binary, then call inspect_artifact. Use detail: "summary" for a large virtual filesystem and inspect_analysis_view to page retained Evidence.
The recognized carriers are a Mach-O __SUI section named d3n0l4nd, an Intel Mach-O <~sui-data~> trailer, an ELF PT_NOTE or SHT_NOTE owned by SUI with type 0x53554901 and descriptor name d3n0l4nd, and a PE RT_RCDATA resource named D3N0L4ND. These are structural layouts. The metadata JSON has no Deno version field, so the compiler version stays unknown unless another record establishes it. Other layouts, including older eszip trailers, are unsupported.
Root metadata reports the carrier, entry point, argv, V8 flags, permission options, unstable configuration, application name, self-extracting marker, virtual-filesystem case sensitivity, and the npm snapshot byte length. The npm snapshot is not decoded. Each virtual file is one occurrence with its logical path, size, and SHA-256. Transpiled output, CJS export analysis, and source maps are separate occurrences beside that file. Each has the same index as the file and its own role. A region normally has the logical path of the file plus a .deno-* suffix. When that path belongs to another stored file, the region moves to an indexed path such as deno-vfs/0.vfs-transpiled, so read the reported logical_path instead of building it from the file name. They are not linked by parent_occurrence_id, which follows directories and expanded containers. Symlink targets stay recorded path parts and are never followed.
Metadata.env_vars_from_env_file holds values from a compile-time --env-file, and ca_data holds certificate bytes. Inventory retains the variable names and values, certificate bytes, counts, and byte lengths in local Evidence, so sharing that Evidence shares them. Extraction does not write them as files.
A virtual filesystem that cannot be listed reports vfs_listing as unsupported and leaves inventory and extraction coverage unknown, because its files are not examined.
Remote modules, redirects, and specifiers contribute counts and logical paths when their stored form is unambiguous. When it is not, they stay present with a byte length and an unsupported member listing. A module whose specifier is missing uses an indexed deno-remote/<index> path, which still exposes its stored bytes, and modules with resolved specifiers keep their paths. Colons, backslashes, and control characters in a specifier are percent-encoded in the logical path, so http://localhost:8000/mod.ts becomes deno-remote/localhost%3A8000/mod.ts. Percent escapes in a logical path use uppercase hex, and a specifier that reaches a path already taken uses an indexed path. source_path keeps the original specifier. A remote specifier is indexed the same way when a path component exceeds 255 UTF-8 bytes or the logical path exceeds 512 UTF-8 bytes, counting the .deno-* suffix of its stored regions. Unsafe, deep, or over-long virtual names use deno-vfs/<index> under the same rule and retain the original spelling when it fits the name allowance. A descendant does not present its own name as a complete source path when an ancestor spelling was dropped.
A length that overruns the section, or a closing marker that does not match, is malformed. An opening marker that is absent is unsupported. A confirmed section that cannot be parsed fails closed and does not fall through to a plain native inventory. An Intel Mach-O sentinel inside a confirmed trailer payload is data of that payload, so an Intel Deno executable stored as a virtual file does not replace the app that stores it. Trailers side by side with different bytes fail closed. A file is confirmed only by its carrier name, so an unrelated native file with malformed tables keeps its native inventory. That inventory does not establish that the file holds no Deno section.
See limits and recovery for the named allowances. Synthetic tests cover the carriers and malformed declarations. Run npm run verify:deno:standalone for a local Deno compile of the host and, when the compiler can produce them, Linux, Windows, and Intel macOS targets. Deno is a fixture producer only and is not installed by REA. The produced executable is not run.
