Entrpi 81f9f71f6d feat(rizin): select the decoder and map address for one-shot commands (#8991)
* feat(rizin): select the decoder and map address for one-shot commands

execute_rizin_command and rea execute-rizin-command accept optional
asm_arch, asm_bits, asm_cpu and base_address (CLI --asm-arch,
--asm-bits, --asm-cpu and --base-address). REA passes them to Rizin
before the artifact path as -a, -b, -e asm.cpu= and -m. Rizin 0.9.1
refuses -e asm.arch= and -e asm.bits= at startup, while -a and -b work
in 0.7.4 and 0.9.1. Rizin applies -e settings after -a and -b.
base_address is the address of file offset 0, as in REA's raw-binary
inputs.

REA checks only the spelling, because Rizin owns the arch and CPU
vocabulary and its builds differ. The Homebrew build of Rizin 0.9.1
has no xtensa or riscv plugin; the official static Linux build of
0.7.4 has both. Evidence records each input and the complete argument
list. When any input is set, Evidence also states that REA does not
confirm the decoder or map that Rizin used: Rizin uses another value
for one it cannot apply and exits 0. Rizin 0.9.1 keeps its default and
reports the value on stderr, and Rizin 0.7.4 turned -b 8 for arm into
16 without a message. Calls without these inputs keep their argument
list and Evidence.

The real-provider gate tests/boundary/providers/RizinDecoderInputs.test.ts
checks the effect of each flag through MCP with Rizin's own e asm.*,
omlj and byte reads. It skips when no Rizin is on PATH. It passes with
Rizin 0.9.1 (Homebrew, macOS arm64) and 0.7.4 (official static build,
Linux x86_64).

* docs(rizin): map multi-segment ESP32 images with om

An ESP32-family app or bootloader image holds several segments, each
loaded at its own address, so one base_address cannot map it. The
recipe removes the default map with om-* and adds one om map per
segment, using the segment offsets from the image format or from
esptool image-info. It does not depend on an ESP image reader in REA.

The offsets were checked against esptool 4.12.0 image_info on a
synthetic two-segment ESP32 image. Rizin 0.9.1 and 0.7.4 mapped its
segments at their load addresses. Rizin 0.7.4, whose static Linux
build has the xtensa plugin, decoded the IRAM segment as nop.n, nop.n,
ret.n and nop.n.

* fix(rizin): read the file at base_address when a loader would claim it

On Rizin 0.9.1, base_address could read 0xff at the mapped address with
exit 0. -m maps the file, but Rizin still runs its format loaders, and
a loose one can claim a raw image. Rizin 0.9.1's AVR loader matches
when bytes 1 and 3 look like rjmp and turns io.va off, so reads use
file offsets. The BIOS loader, in 0.7.4 and 0.9.1, matches a 64 KiB
file with a jmp 16 bytes from its end and maps it at another address.
An acceptance run on a raw ESP32-S3 segment hit the first case.

With base_address, REA now passes -n together with -m. Rizin then skips
the loaders and maps the whole file at the address: rizin.c calls
rz_io_map_new at the -m address and leaves io.va at its default. The
input therefore means a raw image, and Rizin loads no sections, symbols
or entry point, even from an ELF file. Evidence states this in its own
limitation, and the decoder limitation no longer covers the map.

The real-provider gate adds an AVR-like and a BIOS-like image and reads
below the base, at it, at the end of the image and past it. Without -n
it fails on Rizin 0.9.1. It passes with Rizin 0.9.1 (Homebrew, macOS
arm64) and 0.7.4 (official static build, Linux x86_64). The ESP om
recipe now starts with e io.va=true, because reads use the maps only
while io.va is on.

* fix(rizin): advertise name patterns that compile in v mode

The asm_arch and asm_cpu pattern ended its character class with an
unescaped '-', which JavaScript's v (unicodeSets) mode rejects, so
clients compiling advertised patterns in that mode could not use
execute_rizin_command's schema. Escaping it keeps the same names valid
in every mode, as main's own patterns write it.

* fix(rizin): state what the decoder and map inputs leave unconfirmed

The base_address limitation reported a map REA never observes and left
out that -n keeps Rizin's default arch, bits and byte order. The asm_*
limitation implied Rizin replaces a bad CPU, but e asm.cpu echoes any
value. Compact schemas drop property descriptions, so the tool
description now carries the raw-loading warning. The real-provider
gate checks that asm_cpu changes a decode, and a base_address-only call.

* docs(rizin): record the gate's full run on Rizin 0.7.4

* test(rizin): follow the test guide in the decoder input tests

Focused tests resolve execute_rizin_command from its contract family,
the harness owns the temporary directory before setup can fail, and
guidance is compared with its owner, not with sentences from it.

Entrpiandmorluto 0a99c2a580 fix(artifacts): give Godot PCK and Node SEA readers the ESP member lifecycle (#8395)
* feat(artifacts): inventory and extract ESP32 firmware images

ESP32-family app and bootloader images (magic 0xE9) had no reader, so
open_binary refused OTA downloads, app partitions and bootloaders.

Add the esp-image container format behind inspect_artifact and
extract_artifact. A pure decoder reads each byte once and keeps only
fixed-size fields. Derived facts cover the chip, from a table cited to
ESP-IDF v6.1; segment classification as ESP-IDF's should_map and
should_load; checksum and appended SHA-256 results; app and bootloader
descriptors; Secure Boot v2 signature blocks, observed and unverified;
and undescribed trailing byte ranges. Truncation and undescribed bytes
make coverage unknown. ESP8266 images are refused with a specific
reason, and ciphertext stays unrecognized.

Add the format to every target, Evidence, snapshot, live-summary and
artifact vocabulary, document it, and add an optional verify:esp-images
lane that compares esptool-built images with esptool image-info and
espsecure signature-info-v2.

Refs #3615

* test(artifacts): run the ESP image lane on esptool v5.6.0

The lane compared descriptor fields only when esptool image-info printed
one, so a descriptor that REA reports and esptool does not print passed
without comparison. Compare the descriptor kind in both directions.

Record that the lane passed for all 13 images with esptool and espsecure
v5.6.0, the version the layout facts cite, as well as with 4.12.0.

* refactor(artifacts): define ESP image layout sizes once

The decoder and the derived facts each defined the segment-header,
appended-digest and flash-sector sizes, the erased-byte scan and the
offset formatter. Define them once with the other fixed-layout structures
and import them in both places. The signature slot count is the one
constant that drives the slot scan.

Correct the observedEnd comment: it is the end of the last chunk read.

* fix(artifacts): report ESP-IDF's segment length limit by chip

ESP-IDF's verify_segment_header rejects a segment of 16 MiB or more
unless the chip maps flash through 32-bit cache addresses
(SOC_SPI_MEM_SUPPORT_CACHE_32BIT_ADDR_MAP: ESP32-S3, P4, C5, C61, H4 and
S31 in v6.1). Record that capability in the chip table and add a
limitation for such segments; unknown chips get none.

`loaded` repeats should_load. It does not mean the bootloader accepts the
segment: verify_load_addresses still rejects one outside the chip's RAM,
which REA does not model. Say so in the docs, the skill reference and the
inventory limitation.

* test(artifacts): check ESP lane tools first and verify extraction

The lane started work before checking its tools, so a missing RISC-V
target, ld.lld, esptool or espsecure surfaced as a raw spawn or command
error. Check each one before building and name the variable to set. Warn
when esptool is not v5.6.0, the release the layout facts cite.

Assert each segment's class for the ESP32-C3 app, its variants and the
bootloader, as the Xtensa image already did. Extract the app and the
signed image through the CLI and compare every file with the bytes at
esptool's segment offsets or in the appended signature sector; the
source's SHA-256 must be unchanged and equal the reported root_sha256.

* docs(artifacts): state what the ESP image lane does not establish

The Verification section listed the lane's checks but not its gaps: only
ESP32-C3 and ESP32 images come from a real producer, no real project
build, OTA download or flash dump is inspected, no signature is verified,
and the lane does not run in CI.

Record the timing of the final lane run on esptool v5.6.0.

* fix(artifacts): compare ESP segment declarations

Segment entries hash only their data, so compare_artifacts reported a
segment that moved to another load address with the same bytes as
unchanged; only the image itself changed. Compare each segment's
load_addr and data_len as its declaration, as Node SEA and PyInstaller
members are compared, and count a changed declaration as a metadata
change, also when content is unavailable.

Header offsets are layout and the classification is derived, so neither
is compared.

* test(artifacts): run ESP lane commands as owned process trees

The lane ran its tools through execFile. A timeout killed only the direct
child, so a linker or assembler that Clang or GCC had started could keep
running while the lane removed its workspace. Run every command through
createVerifierCommands, check the tools inside withVerifierCleanup, and
remove the workspace only after commands.close() has stopped every tree;
a failed close keeps the workspace.

Only a nonzero exit now counts as a refusal or an expected esptool
failure; timeouts and spawn failures propagate. Supervising each command
roughly doubles the lane's run time.

* test(artifacts): cancel ESP decoding after its first decoded chunk

The cancellation test requested cancel or close on setImmediate, which
can land while the file is still being opened and checked, so it never
showed that decoding had started. It also passed against a reader that
ignored both requests while decoding. Acknowledge the decoder's first
chunk, then cancel or close, join the operation, and assert that no
later chunk reaches the decoder and that the reader ends closed.

* docs(artifacts): record which ESP metadata comparison ignores

Segments are compared by their declaration. The image's and the
signature blocks' format_metadata are not: every field comes from their
own bytes, which content comparison already covers, and a block's
image_digest_matches follows the image's content.

* feat(artifacts): inventory and extract ESP flash layouts

A whole-flash dump of an ESP32-family chip was read as its bootloader
image, with the partition table, apps and data left as undescribed bytes,
or refused when it began with erased flash. Read it as an esp-flash-image
container instead.

The partition table is decoded as esp_partition_table_verify accepts it
and is found at the caller's partition_table_offset, at the default
0x8000, or by scanning 0x1000-aligned sectors for a table whose MD5
verifies, which the inventory reports as derived. The bootloader is
located at its chip's ROM bootloader offset. Each partition is an entry
with its declaration in flat format_metadata; the bootloader and app
partitions carry ESP image facts from the existing streaming decoder; the
otadata records are reported with a selection derived without rollback or
anti-rollback, and the running partition stays unknown. One unreadable
partition does not hide the others, and extraction writes every partition,
nvs_keys included, as ordinary data.

Flash layouts are detected before single ESP images. The scan runs only
when an ESP image sits at a ROM bootloader offset, and is refused when a
bootloader at another chip's offset shows that the dump does not start at
flash address 0. open_binary gains flash_offset and partition_table_offset,
which require format esp-flash-image and are part of the snapshot target
identity; the CLI takes them with --target-format esp-flash-image.
Comparison treats a partition's label, type, subtype, range and flags as
its declaration.

* test(artifacts): verify ESP flash layouts with gen_esp32part, merge-bin and otatool

Add the optional verify:esp-flash lane. It builds default and relocated
partition tables with ESP-IDF's gen_esp32part.py, assembles dumps with
esptool merge-bin, including one written from flash 0x1000, and writes
OTA records with otatool through flash_file_tool.py, which replaces
parttool's esptool calls with reads and writes of the dump file.

It compares REA's bootloader and app facts with esptool image-info, every
partition with gen_esp32part.py's decoding of the extracted table, and the
OTA records and derived slot with otatool read_otadata after each switch.
It also checks extracted bytes and source integrity, the scan and caller
table offsets, flash_offset on the 0x1000 dump, a corrupted app beside
valid partitions and a truncated dump. ESP32 linker scripts place the
conformance bootloader and app in ESP32 address ranges.

* fix(artifacts): read ESP flash layouts as the bootloader does

Read the partition table as bootloader_utility_load_partition_table
does: the last factory, otadata and same-subtype OTA declaration wins,
and a limitation names repeats. Plan each otadata record within its
partition and the dump. An otadata partition smaller than two sectors
selects none, the bootloader's INVALID_INDEX; a record the dump lacks
leaves the selection unknown while the other record stays reported. The
fallbacks follow the bootloader's indexes: ota_0-fallback and
factory-fallback name no partition when the table declares none, and the
assumptions add GPIO holds and deep-sleep wake.

Refuse a dump whose bootloader contradicts its origin before the default
table offset is tried, whether flash_offset was omitted or given, and keep
the ESP image reader's ESP8266 refusal. A table never lies inside the
located bootloader image, so single app images are no longer scanned. An
explicit esp-flash-image selection is decided before other container
signatures, and the native commands' --target-format no longer takes it.
Say when no bootloader confirms the default origin.

Exempt the primary bootloader and partition_table entries of ESP-IDF 5.3
from placement limits, report every region inside a longer one, and name
partitions by index when labels repeat ignoring case. Keep an undecodable
label's bytes in label_hex and compare them. Word undescribed ranges as
starting at a byte that is not erased, and treat a short erased region as
erased.

Add an MCP compare_artifacts test for partition declarations, reader
identity and close tests, scan edge cases, the 0x2000 ROM offset and a
literal otatool CRC.

* test(artifacts): verify ESP primary layout entries and the otadata fallback

Build a table with the primary bootloader and partition_table entries
that gen_esp32part.py fills from --primary-bootloader-offset, and check
that REA reads it with complete coverage, no overlap or misplacement
limitation, and a table that agrees with gen_esp32part's decoding. Erase
the otadata with otatool after the slot switches and check the records
against read_otadata and the factory fallback.

* refactor(artifacts): share positional entry lifecycle

The ESP image and ESP flash-layout readers carried the same 138 lines of
lifecycle code. PositionalArtifactReader now owns it: one preparation
under the reader's scope, a carrier recheck before each traversal,
refusal of forged entries, range streams that check their length and
recheck the carrier when they end, and a close that retires open
streams before it releases the carrier.

Each reader keeps its location, decoding, entries and metadata, and
returns its entries and coverage from prepareEntries(). Entries carry a
required byte range, which removes the unreachable null-range checks in
open(). Failure reasons, messages, order and cancellation do not change.

The Godot PCK reader keeps its own copy. It reports a member that ends
early as a format failure, where the ESP readers report integrity, and
the helper cannot express that without an option. The Node SEA reader
has the same difference.

* fix(artifacts): report Godot PCK and Node SEA members that end early as integrity

Behavior change: a Godot PCK or Node SEA member stream that delivers
fewer bytes than its entry declares now fails with reason "integrity"
and the message "<label> entry ended early: <path>". Before, it failed
with reason "format" and "<label> is malformed: member ended early:
<path>". Callers see the category integrity_mismatch instead of
execution_failure. The remediation text does not change.

Only a carrier that changes after open() rechecks its identity reaches
this path. The directory was valid when the inventory was taken, so a
short member means that the carrier changed, not that it is malformed.
The identity recheck that runs next also reports integrity, and the ESP
and ASAR readers already report a short member as integrity.

The new tests end the admitted descriptor's reads inside a member after
open() and check the reason and message for each reader.

* refactor(artifacts): move Godot PCK and Node SEA onto the positional lifecycle

The Godot PCK and Node SEA readers carried their own copies of the
positional entry lifecycle. They now extend PositionalArtifactReader and
keep only their location, decoding, entries and metadata.
prepareEntries() returns the entries and the coverage that each reader
reported before. Godot reports unknown coverage with one limitation for
an encrypted or sparse-bundle directory. Node SEA reports complete
coverage with its fuse contradiction as a limitation.

The base class takes two rules from these readers:

- open() refuses an encrypted entry as unavailable, after the
  forged-entry check and before the carrier recheck: "Encrypted <label>
  member is unsupported: <path>". ESP entries are never encrypted.
- Traversal yields to the event loop every 256 entries, starting before
  the first entry. The ESP readers gain one yield before their first
  entry. This changes scheduling only.

Failure reasons, messages, order and cancellation do not change. A
member that ends early has failed as integrity since the previous
commit. Godot's directory parse still checks only cancellation, so close
does not stop it early. Node SEA's close still drops an admitted decode
that no completed preparation released. Each reader now stores its
entries only after preparation succeeds; a failed preparation never
served them before either. PositionalArtifactEntry requires a byte
range, so the unreachable null-range checks in open() are gone.

* fix(artifacts): keep ESP flash coverage complete for a dump cut short

An esptool merge-bin dump ends after the last part it wrote, usually inside
its last partition. Such a partition made the layout's coverage unknown, so
artifact comparison of two merge-bin dumps reported every unchanged
partition as unknown.

The partition table names every partition whatever the file's length, so a
partition cut short or left out by the end of the file hides no entry. As
the ESP image reader does for a cut-short segment, its entry holds the bytes
the file has and an entry limitation gives the declared size; a partition
with no bytes stays in partitions_outside_dump. Coverage stays complete
unless undescribed bytes remain or no bootloader is located. An MCP
compare_artifacts test of two dumps that end inside ota_0 now classifies
every partition, and fails on the old rule.

* fix(artifacts): report written bytes in ESP partitions, erased slots included

An app slot is erased for ESP-IDF's bootloader when its image header bytes
are erased flash, and REA reported only that status. A slot can still hold
data further in: a dump read from a device held a complete older app image
1 MiB into an OTA slot reported as erased, with no limitation.

Each partition entry now records where the bytes the dump holds are
written, relative to the partition: written_offset, the first byte that is
not 0xFF, written_end, just past the last, and written_bytes, how many are
not 0xFF. They are null for a partition outside the dump. The status stays
erased, which is the bootloader's view, and a limitation names an erased
app slot that holds written bytes and says they are not read as an image.
The reader reads every partition byte once more to find them.

* fix(artifacts): derive the ESP boot selection for every partition table

The boot selection lived inside otadata, so a table without an otadata
partition, the common factory-only layout, had none. ESP-IDF's
bootloader_utility_get_selected_boot_partition returns the factory index
when the table declares no otadata partition.

Move it to a top-level boot_selection that every layout has. Its basis
names the bootloader's branch: otadata, factory-fallback and ota_0-fallback
from the records, no-otadata for a table without otadata, none for the
bootloader's INVALID_INDEX, and unknown when the dump lacks a record the
bootloader reads, which replaces the null selection. running_partition
moves with it, and otadata keeps its partition index and records. The
assumptions name what each branch leaves out: no records assumption
without otadata, and none for none or unknown. The real-tool lane checks
no-otadata on a table gen_esp32part built without otadata.

* fix(artifacts): say when an ESP image is a flash dump read from 0x1000

An ESP32 dump read from flash 0x1000, as read-flash 0x1000 or merge-bin
--target-offset 0x1000 writes it, opened automatically as its bootloader
image with a megabyte of undescribed bytes and no next probe. The flash
reader refuses that origin, but nothing told an agent which flash_offset to
pass.

espFlashDumpOrigin owns the inference: an image of a chip whose ROM loads
the bootloader from flash R, at file offset F, is the bootloader of a dump
read from R - F when a partition table sits where that origin puts 0x8000.
The ESP image reader asks it for a non-app image at file offset 0, so the
result does not depend on how the reader was created, and records
flash_dump {flash_offset, table_file_offset}, null otherwise, with a
limitation that says to reopen the file as esp-flash-image with that
flash_offset. inspect_artifact proposes the same open_binary call as a next
probe, and the flash reader's misplaced-origin refusal names the offset.

* perf(artifacts): summarize nested ESP images in the flash layout summary view

The summary view returned an ESP flash layout's root facts whole, so each
app partition and the bootloader carried every segment and signature
block, about half of a dump's summary.

The summary view now gives each nested image a summary instead of its
facts: status, chip, entry point, segment count, load ranges (each mapped,
loaded or unclassified segment's address and declared length), the
checksum and appended SHA-256 statuses, coverage and limitations. Complete
detail keeps the full facts, every segment included, and the retained
Evidence is unchanged. On a 16 MiB device dump the summary's root falls
from 5,141 to 2,657 bytes, and the summary Evidence from 10,038 to 7,554.

* test(artifacts): expect the misplaced image the ESP bootloader search reports

8a748d3cc added misplacedImage to the bootloader search, which the
locator uses to name the origin a misplaced bootloader implies, but one
test still compared the search result without it. Expect the image's
chip and file offset, and no image for an unknown chip.

* fix(artifacts): give every ESP partition from the dump's start an entry

After ecbc1a772 kept coverage complete for a dump cut short, a partition
wholly past the end of the file still had no entry, only a
partitions_outside_dump row. Comparing a merge-bin dump with a full device
read then reported that partition as added or removed, as if one table
did not declare it.

Every partition from the dump's first byte on is now an entry holding the
bytes the file has: none for one past the end, with a limitation saying
the file holds none of its bytes, no image facts and null written fields.
partitions_outside_dump keeps only partitions that begin before the dump's
first byte, and coverage is unknown when one does, since it has no entry.
Two dumps that lack the same partition now compare it as unchanged, and a
dump against a longer one reports the partition as changed; an MCP test
of a merge-bin dump against a full one checks that no path is added or
removed.

Unlike the ESP image reader, which marks a truncated image's coverage
unknown because later segments and signature blocks may be hidden, the
flash reader can list every partition from the table whatever the file's
length; only the entry limitation follows the image reader.

* fix(artifacts): select no ESP app from a partition table the bootloader rejects

boot_selection followed bootloader_utility_get_selected_boot_partition but
not the table check before it. For a table whose MD5 does not match, or
that has a second MD5 entry, esp_partition_table_verify fails, the
bootloader selects no app and resets. REA still derived a slot from the
otadata records, although the table's own limitation said the bootloader
rejects it.

The selection now has basis none, with no assumptions, for a table the
decoder marks invalid. It also follows two more branches of the
bootloader: an otadata partition at offset 0, which the bootloader takes
for none, selects the factory index as no-otadata, and a table without an
OTA app selects its fallback even when the dump lacks a record, since the
bootloader then ignores the records.

The bootloader also rejects a table whose partitions end past the flash
size in its header. REA does not model that check; the format guide says
so.

* fix(artifacts): require the ESP dump origin's table to follow the image

espFlashDumpOrigin named a later flash origin whenever a partition table
decoded where that origin puts 0x8000. Bytes inside the image's own
segments could be read that way, so an ESP32 bootloader whose segment data
held table-shaped bytes at file offset 0x7000 was reported as a dump read
from 0x1000.

The table must now start at or after the image's end, the rule the locator
already applies to the default table. The ESP image reader passes the
image_end it decoded, or the file size for a truncated image; the flash
reader's refusal passes the end of the misplaced image's segments. The
bootloader search drops its misplaced flag, which only restated
misplacedImage, and the next probe formats offsets with offsetText.

Reader tests cover the 0x1000 and 0x2000 ROM offsets, a standalone
bootloader, bytes that begin like a table, an app with a table at 0x7000
and a table inside a segment; without the boundary check, three of them
fail.

* fix(artifacts): give the ESP flash summary its own kind and each image's identity

The summary view's ESP flash root kept kind esp-flash-image, so a consumer
bound to kind could not tell an image's summary from its full facts, and
the advertised schema held two objects with the same kind const. It is now
esp-flash-image-summary.

The per-image summary also dropped the descriptor, which is what tells two
app slots apart, and named each image only by its partition index, which
the summary view, having no entry rows, could not resolve. Each nested
image now carries its entry path from the layout plan, in both views. The
summary adds the descriptor kind with its identifying fields (an app's
project_name, version, idf_ver, secure_version and app_elf_sha256; a
bootloader's version, idf_ver and secure_version), the signature block
count and each load range's classification. Its enums and fields derive
from the schemas that own them.

An MCP test reads a dump with an app in ota_0 and an erased ota_1 that
holds older bytes: it checks both summaries, that the summary's inventory
Evidence is the one the complete view returns with full facts, and the
erased slot's written range.

* test(artifacts): cover cancel and close during the ESP written-bytes scan

The written-bytes pass reads every byte of each partition the dump holds,
checking that the reader is open before each chunk, but only app decoding
had a cancellation and close test. A data partition, which only that pass
reads, now holds 9 MiB; once the scan has examined its first chunk, a
cancel rejects preparation with the caller's reason and a close with
unavailable, and the scan examines no further chunk.

The erased-slot test now asserts the whole set of erased-slot limitations,
so factory, ota_0 and nvs, which the bootloader reads or which are not app
slots, are shown to have none.

* docs(artifacts): re-time the ESP flash lane and state only observed causes

The lane ran again after its assertions changed; both esptool runs passed,
and the timed run's figures replace the earlier ones. The erased-slot
paragraph no longer names a cause for the older bytes, which REA cannot
observe, and the skill reference states that every table has a
boot_selection in its own sentence, with the none basis for a table the
bootloader rejects.

* test(artifacts): open an ESP partition past the end through the positional reader

A partition that lies past the end of a dump is an entry with no bytes,
and the merge with the positional lifecycle gives it the empty range at
the end of the file. The inventory tests listed that entry but never
opened it. Opening it through the shared reader now yields no bytes, and
its range is the file's size with a declared size of 0.

* fix(artifacts): retire ESP flash members as the ESP image reader does

#7498's maintainer commits made the ESP image reader keep a member owned
until its consumer closes it, retire fully buffered bytes when
cancellation arrives after production, and refuse to finish an inventory
paused across close. The ESP flash reader was copied from the earlier
reader. Main's shared stored-member lifecycle cases failed two of eight
against it: a paused inventory completed after close, and buffered member
bytes stayed readable after cancellation.

Give the flash reader the same lifecycle and run the shared cases against
it.

* docs(artifacts): re-time the ESP flash lane after merging main

The lane passed again with esptool v5.6.0 and 4.12.0 on the merge of upstream main. Record the v5.6.0 run's time and peak resident set.

* fix(artifacts): read ESP image Evidence recorded before flash_dump

The flash layout work made `flash_dump` a required field of the
`esp-image` root metadata. Evidence recorded before it has no such
field, so newer REA rejected records that were valid when they were
made: `compare_artifacts` and `inspect_analysis_view` reported
`evidence_integrity_mismatch` for them.

The field is now optional when read. A record without it parses as it
is, so the graph digest it commits to still matches; nothing fills the
field in. The image reader still writes it for every image, and the
inspection probe reads a missing field as no hint.

A regression test recommits an image inventory without the field and
passes it inline to `compare_artifacts` and `inspect_analysis_view`.
Against a server built with the required field, `compare_artifacts`
rejects it.

* fix(artifacts): stop the ESP flash gap scan when the reader closes

The scan for the first written byte in each undescribed gap checked
only the caller's signal. `close()` marks the reader closed and waits
for preparation, so it waited while the rest of a long erased gap was
read.

The gap scan now takes the reader's open check, as the written-bytes
scan and the image decoder do, and checks it before each chunk. Tests
cancel or close the reader after the scan's first chunk of a 9 MiB
erased gap and confirm that no later chunk is examined.

* fix(artifacts): name ESP partitions with Windows device labels by index

The safe-label rule accepted labels such as `NUL`, `con` or `COM1`, so
extraction wrote `partitions/NUL.bin`. Windows reserves those names
before any extension, and ordinary Windows tools cannot use such a
file.

A label that is a Windows device name (`CON`, `PRN`, `AUX`, `NUL`,
`COM0`-`COM9` and `LPT0`-`LPT9`, any case, alone or before a dot) now
takes the existing index fallback. The partition metadata and the
entry's source path keep the label.

* fix(artifacts): read ESP flash partitions' written bytes in one pass

Each partition got its own scan of the bytes the dump holds, so
partitions declared over the same bytes read them again and again.
Overlaps only add limitations, so a crafted table reached this normally:
94 overlapping partitions over a 32 MiB dump would examine about 3 GiB
before the first entry.

The reader now reads the bytes the partitions cover once. Partition
boundaries cut them into segments; one pass counts each segment's
written bytes and bounds, and each partition's extent is the sum of the
segments inside it. Every partition keeps its own declaration, extent
and limitations. The pass checks the reader's open state before each
chunk, as the per-partition scan did.

A test declares 60 partitions over one MiB, 40 over all of it and 20
over its first half, and checks each partition's extent and the
overlap limitations. The reader reads 1,113,256 bytes of the
1,114,112-byte dump; one scan per partition read 52,493,480.

* test(artifacts): fail the ESP lanes on failed commands and refusals

`otatool` turned a nonzero exit into returned text, which its callers
discarded, and `inspect()` returned `{ refused }`, which the flash lane
never checked. A failed command then surfaced later as a slot
assertion, an output-parser error or a TypeError, hiding its cause.

Commands the lanes need to succeed now reject with the output they
exited with: `otatool` and `inspect()` do so through a shared
`failedCommand`. An expected refusal is opt-in: `refusal()` returns
REA's output and fails the lane when REA opens the file. The ESP image
lane's two ESP8266 cases use it.

Checked by calling `otatool` on a file without a table, `inspect()` on a
file REA refuses and `refusal()` on a file REA opens; each rejects with
its cause.

* fix(artifacts): require a partition entry in an ESP partition table

The decoder counted the slot, not the partitions, so a lone MD5 entry
over the empty prefix, followed by the terminator, decoded as a table
with no partitions. Default and caller-selected detection then accepted
that empty layout, although the guide requires one partition.

A table now needs one partition entry before its terminator. An MD5
entry alone is refused as `entry 1 at 0x20 ends the table before any
partition entry`. The cases cover the decoder and both automatic and
caller-selected location.

* fix(artifacts): decode an image shared by ESP app partitions once

Each app partition got its own decode, so app partitions declared over
the same bytes decoded and hashed the same image again and again, the
same pattern the written-bytes scan had. With 60 app partitions over
one 960 KiB image the reader read 64,029,736 bytes of a 1,114,112-byte
dump.

Regions with the same file range now share one decode; each keeps its
own copy of the facts. Partitions with different ranges still decode
separately, because truncation can change the facts: at most one decode
per partition the table holds, each within its partition.

A test declares 60 app partitions over one image, 40 holding all of it
and 20 cutting it short, and expects three decodes: the bootloader, the
whole image and the cut one. The 60-partition dump now reads
2,161,864 bytes, as a dump with one app partition does.

* test(artifacts): run the shared member lifecycle cases on Godot PCK and Node SEA

The Godot PCK and Node SEA readers now extend PositionalArtifactReader,
whose member lifecycle comes from #7498's ESP reader. Main's shared
stored-member cases ran only for the ESP and uImage readers. Run them for
these two readers as well.

On main `6e9ee97a6`, both readers fail two of the eight cases: a paused
inventory finishes after `close()`, and member bytes buffered before
cancellation stay readable. On the positional base, all eight pass.

Entrpi c13dd36d95 fix(artifacts): decide how compare_artifacts compares every format_metadata kind (#8231)
* feat(artifacts): inventory and extract ESP32 firmware images

ESP32-family app and bootloader images (magic 0xE9) had no reader, so
open_binary refused OTA downloads, app partitions and bootloaders.

Add the esp-image container format behind inspect_artifact and
extract_artifact. A pure decoder reads each byte once and keeps only
fixed-size fields. Derived facts cover the chip, from a table cited to
ESP-IDF v6.1; segment classification as ESP-IDF's should_map and
should_load; checksum and appended SHA-256 results; app and bootloader
descriptors; Secure Boot v2 signature blocks, observed and unverified;
and undescribed trailing byte ranges. Truncation and undescribed bytes
make coverage unknown. ESP8266 images are refused with a specific
reason, and ciphertext stays unrecognized.

Add the format to every target, Evidence, snapshot, live-summary and
artifact vocabulary, document it, and add an optional verify:esp-images
lane that compares esptool-built images with esptool image-info and
espsecure signature-info-v2.

Refs #3615

* test(artifacts): run the ESP image lane on esptool v5.6.0

The lane compared descriptor fields only when esptool image-info printed
one, so a descriptor that REA reports and esptool does not print passed
without comparison. Compare the descriptor kind in both directions.

Record that the lane passed for all 13 images with esptool and espsecure
v5.6.0, the version the layout facts cite, as well as with 4.12.0.

* refactor(artifacts): define ESP image layout sizes once

The decoder and the derived facts each defined the segment-header,
appended-digest and flash-sector sizes, the erased-byte scan and the
offset formatter. Define them once with the other fixed-layout structures
and import them in both places. The signature slot count is the one
constant that drives the slot scan.

Correct the observedEnd comment: it is the end of the last chunk read.

* fix(artifacts): report ESP-IDF's segment length limit by chip

ESP-IDF's verify_segment_header rejects a segment of 16 MiB or more
unless the chip maps flash through 32-bit cache addresses
(SOC_SPI_MEM_SUPPORT_CACHE_32BIT_ADDR_MAP: ESP32-S3, P4, C5, C61, H4 and
S31 in v6.1). Record that capability in the chip table and add a
limitation for such segments; unknown chips get none.

`loaded` repeats should_load. It does not mean the bootloader accepts the
segment: verify_load_addresses still rejects one outside the chip's RAM,
which REA does not model. Say so in the docs, the skill reference and the
inventory limitation.

* test(artifacts): check ESP lane tools first and verify extraction

The lane started work before checking its tools, so a missing RISC-V
target, ld.lld, esptool or espsecure surfaced as a raw spawn or command
error. Check each one before building and name the variable to set. Warn
when esptool is not v5.6.0, the release the layout facts cite.

Assert each segment's class for the ESP32-C3 app, its variants and the
bootloader, as the Xtensa image already did. Extract the app and the
signed image through the CLI and compare every file with the bytes at
esptool's segment offsets or in the appended signature sector; the
source's SHA-256 must be unchanged and equal the reported root_sha256.

* docs(artifacts): state what the ESP image lane does not establish

The Verification section listed the lane's checks but not its gaps: only
ESP32-C3 and ESP32 images come from a real producer, no real project
build, OTA download or flash dump is inspected, no signature is verified,
and the lane does not run in CI.

Record the timing of the final lane run on esptool v5.6.0.

* fix(artifacts): compare ESP segment declarations

Segment entries hash only their data, so compare_artifacts reported a
segment that moved to another load address with the same bytes as
unchanged; only the image itself changed. Compare each segment's
load_addr and data_len as its declaration, as Node SEA and PyInstaller
members are compared, and count a changed declaration as a metadata
change, also when content is unavailable.

Header offsets are layout and the classification is derived, so neither
is compared.

* test(artifacts): run ESP lane commands as owned process trees

The lane ran its tools through execFile. A timeout killed only the direct
child, so a linker or assembler that Clang or GCC had started could keep
running while the lane removed its workspace. Run every command through
createVerifierCommands, check the tools inside withVerifierCleanup, and
remove the workspace only after commands.close() has stopped every tree;
a failed close keeps the workspace.

Only a nonzero exit now counts as a refusal or an expected esptool
failure; timeouts and spawn failures propagate. Supervising each command
roughly doubles the lane's run time.

* test(artifacts): cancel ESP decoding after its first decoded chunk

The cancellation test requested cancel or close on setImmediate, which
can land while the file is still being opened and checked, so it never
showed that decoding had started. It also passed against a reader that
ignored both requests while decoding. Acknowledge the decoder's first
chunk, then cancel or close, join the operation, and assert that no
later chunk reaches the decoder and that the reader ends closed.

* docs(artifacts): record which ESP metadata comparison ignores

Segments are compared by their declaration. The image's and the
signature blocks' format_metadata are not: every field comes from their
own bytes, which content comparison already covers, and a block's
image_digest_matches follows the image's content.

* fix(artifacts): decide declaration comparison for every metadata kind

compare_artifacts listed the format_metadata kinds it compared by hand,
so a new kind went uncompared without notice; ESP segment load addresses
were first missed this way. One table beside the schemas now gives every
kind a declaration projection or the reason comparison uses none of its
facts, and a kind without an entry does not compile. Consumers read one
result per pair instead of naming formats.

- Godot PCK entries stay uncompared. Godot looks members up by the
  simplified path without res://, which logical_path holds apart from
  Unicode normalization. Godot 4.3 exports store res:// and 4.4.1
  exports do not, so comparing source_path would mark every member
  changed. The reader admits only the encryption flag, which the
  occurrence's encrypted field records.
- A changed PyInstaller declaration is now a metadata change also when
  the member's content is unavailable, as for ASAR, Node SEA and ESP
  segments. It was unknown before, for no recorded reason.
- Root kinds and ESP signature blocks stay uncompared: their fields come
  from their own bytes, which content comparison covers.
- A declaration that only one side records now adds one generic
  limitation for every compared kind. Only Node SEA added one before,
  with its own text.

* fix(artifacts): keep content comparison for metadata records with content

The record rule compared two metadata occurrences by their declaration
alone. A hand-built record that names content, with an equal declaration,
then hid a content change; PyInstaller records already did so before the
table. The rule now needs both records without an artifact_id, which is
every metadata record a reader emits.

Review changes in the same area:

- The unknown-declaration limitation also covers declarations of different
  kinds and non-container observations, and tests compare it with its
  constant.
- docs/godot-pck.md gives each Godot version's lookup path, the backslash
  case, and that a member that becomes encrypted compares unknown. The
  table points to it instead of restating it.
- The PyInstaller regression moves to an acceptance test whose MCP client
  validates the advertised output schema, and the domain tests keep one
  representative case per behavior.

* fix(artifacts): compare encryption changes when content is unavailable

An encrypted member has no content. Comparison then took the
content-unavailable fallback, which counted only ASAR storage and format
declarations, so a Godot PCK, ZIP or PYZ member that became encrypted
compared unknown although both sides record `encrypted`. The record rule
compared node-less metadata records by format declaration alone, so a PYZ
namespace record whose encryption flipped compared unchanged.

`OccurrenceMetadata` now owns the encryption comparison beside ASAR
storage and the format declaration. Every occurrence records `encrypted`,
so a pair's comparison is never unknown. The fallback, the record rule and
the metadata dimension read it there; `metadataChanged` no longer compares
`encrypted` itself. The record rule compares all of `OccurrenceMetadata`:
a changed value is changed in metadata, with availability when another is
unknown.

Decision: occurrence limitations still do not count for node-less
records. Readers derive them from the declared facts (the PYZ caveat
follows `encrypted`), and their wording can change between REA versions
while the record stays the same. The fallback does not compare them
either.

Behavior changes:
- A pair with unavailable content whose `encrypted` differs is changed
  [metadata, availability], not unknown [availability].
- A node-less record whose `encrypted` differs is changed [metadata], not
  unchanged.
- A hand-built node-less record that records ASAR storage now compares
  it; no reader emits such records.

Remaining:
- The fallback still ignores `entry_kind` and `executable`, which readers
  also declare, so a file that becomes a symlink, or a mode change on an
  encrypted ZIP member, still compares unknown. `executable` has its own
  dimension, so its fix needs content-free checks split from node checks.
  Each is its own behavior decision.
- Node-bearing pairs still compare limitation wording; records do not.
  Whether limitation wording is ever a comparison fact needs one decision.

* fix(artifacts): compare entry kind and executable when content is unavailable

When either side lacked verified content, comparison took a fallback that
counted only ASAR storage, encryption and format declarations. It compared
`entry_kind` only in the metadata check of pairs with content, and
`executable` only beside the node checks. A ZIP member that became a
symlink, whose target REA does not read, and an encrypted ZIP member whose
Unix mode gained an execute bit therefore compared unknown, although
readers declare both fields on every occurrence.

`OccurrenceMetadata` now owns the entry kind comparison beside encryption;
it is never unknown. Comparison checks fall into two groups: declared facts
that need no content (`executable` and the metadata declarations), and
facts that need both content nodes (content, kind, format, size, relations
and node metadata). The fallback, the record rule and pairs with content
share the declared checks and one rule for unknown declarations. Kind and
format stay content checks: without content they are guesses from the path.

Behavior changes:
- Unless both sides have content, a pair whose entry kind differs is
  changed [metadata, availability], not unknown [availability].
- Such a pair whose `executable` differs is changed [executable,
  availability], with metadata when another declared fact also differs.
- A hand-built node-less record whose `executable` differs is changed
  [executable]. No reader emits such records.

Remaining: declared sizes and integrity digests still compare only through
observed bytes, so they do not count when content is unavailable.

* fix(artifacts): never mark a symlink executable

On POSIX hosts the directory reader recorded a symlink's own permission
bits as `executable`. Linux reports 0777 for every symlink and macOS
usually 0755, so directory, app bundle and DMG symlinks read true. zip.js,
the PyInstaller reader and the Windows branch record false. The previous
commit compares `executable` without content, so a symlink that two
readers or two hosts record differently compared changed in `executable`,
and a non-executable file that became a symlink also reported `executable`.

`hostExecutableMarking` now gives a symlink no marking on any host:
running a symlink runs its target, and the link's own bits do not control
that.

Behavior change: directory, app bundle and DMG inventories record
`executable: false` for symlinks. Occurrence IDs do not change, but the
graph digests and manifest IDs of inventories with symlinks do. Comparing
an inventory stored before this change with a new one therefore reports
changed [executable, availability] once for each such symlink.

* fix(artifacts): stop comparing limitation wording

Pairs with content compared node and occurrence limitations as metadata,
while node-less records, the content-unavailable fallback and inventory
limitations did not. Limitations explain what an observation could
establish. Readers mostly derive them from fields that comparison already
reads, from other occurrences or from what REA could read, and their
wording changes between REA versions. So adding `A` beside an unchanged
ZIP member `a` marked `a` changed in metadata through its case-collision
note, and an older and a newer inventory of equal bytes could differ
wherever a reader reworded a note.

No comparison path reads limitations now. Inventory limitations still
appear in the result, and occurrence limitations stay in the inventory
Evidence. Readers write no node limitations, so only hand-built inventories
compared them.

Behavior change: for a pair with content, limitation text no longer adds
metadata. A pair that differs only there compares unchanged, or unknown
[availability] when a declaration is unknown.

Remaining: a few facts appear only in limitation text, or also in fields
that comparison does not read, so their changes are no longer reported
while the compared bytes stay equal: an ASAR block integrity table or an
unsupported integrity declaration, a Godot member's all-zero MD5, a ZIP
name's leading `./` (also in `source_path`), and a PyInstaller PYZ image
digest (also in `pyz_sha256`; the archive root still reports the change).
Each needs a field or a comparison decision of its own if it matters.

* fix(artifacts): compare declared digests when content is unavailable

Without observed bytes on both sides, comparison ignored the containers'
declared integrity claims. Two encrypted Godot PCK members therefore
compared unknown even when their declared MD5s showed that the script had
changed. Godot's exporter stores the MD5 of a member's original bytes, so
the MD5 does not depend on the encryption IV. This comes from the 4.3,
4.4.1 and 4.7.1 exporter sources; no real encrypted export was compared.

When either side has no content, claims of one algorithm that differ now
make the path changed in metadata and availability. Equal claims add no
change, because they are unverified, and observed bytes still decide when
both sides have them. Godot PCK and ASAR readers record such claims.

For a readable member, a directory that declares or omits an MD5 only
decides whether REA can check its bytes, so such a member compares
unchanged. An encrypted member with an MD5 on only one side stays unknown.

Remaining: declared sizes still compare only through observed bytes.

* docs(artifacts): check the contract's compared kinds against the table

docs/mcp-contracts.md named the format_metadata kinds that
compare_artifacts compares in prose, by hand, so a kind added to the
declaration table could go unnamed. The integration branch already omits
esp-flash-partition, which the ESP flash layout branch adds to the table.

The paragraph now names each compared kind by its identifier. A
conformance test requires it to name exactly the kinds whose table entry
has a declaration, which artifactFormatMetadata.ts exports as
COMPARED_FORMAT_METADATA_KINDS, and no kind that comparison ignores.

* test(artifacts): share the comparison acceptance MCP fixture

Six artifact comparison acceptance tests each copied the same MCP
steps: open_binary, inspect_artifact, the inventory_artifact substep
Evidence, then compare_artifacts. The coverage test repeated the
inspect steps three times and kept its own inventory lookup.

tests/fixtures/artifactComparisonMcp.ts now owns these steps on the
schema-validating connectLocalToolsMcp client.
connectArtifactComparisonMcp() returns call, inspect(path) and
compare(left, right). inventoryEvidence() reads the inventory Evidence
that an inspection retains, from MCP or CLI output. Each test still
writes its own authored input and keeps its expectations.

The coverage lookup matched evidence.operation, not the substep
operation. The inspection schema fixes both to inventory_artifact, so
both select the same substep.

The plist acceptance test does not change. It compares the inspection
Evidence itself across CLI and MCP and passes the comparison Evidence
to verify_reconstruction and find_changed_behavior.

No assertion or scenario changes.

* fix(artifacts): leave .NET bundle member declarations uncompared

Upstream main compares no .NET bundle member facts. Comparing `file_type`
changed `compare_artifacts` output beyond this branch's fixes, so the kind
stays uncompared until that is decided. A changed manifest still shows as a
content change of the host.

* fix(artifacts): leave HEX region declarations uncompared

The comparison table compared a region's start_address and length. A
region's path names its start and end addresses, and its length follows
from them, so two regions that pair at one path always declare the same
facts: the entry could never find a change. It only made a region with
equal bytes unknown when the other side recorded no metadata, such as a
directory of extracted regions. The kind is not compared, as on main.

The contract paragraph also stops naming .NET bundle members, which
3e51a7760 left uncompared.

* test(artifacts): compare node-less records of any compared kind

The record rule follows the comparison table, not PyInstaller, but only
PyInstaller records exercised it. An ESP segment record shows both
outcomes: an equal declaration compares unchanged and a moved one changed
in metadata, without the availability that the fallback for unread
content would add.

* test(artifacts): compare a node-less record's recorded ASAR storage

The record rule compares ASAR storage beside the declaration and
`encrypted`, but no test recorded it on a metadata record. A changed
value is changed in metadata, and a value that only one side records
is unknown in availability, as for any occurrence.

* test(artifacts): compare UnityFS member declarations through MCP

The table compares a UnityFS member's declared source_path and raw
flags, but no comparison test covered the kind, so dropping either field
from the projection left every test passing. Bundles with equal member
bytes now show both: other flags, or a stored path in decomposed form,
compare changed in metadata, and reordered members, whose index and
stream offset are layout, compare unchanged.

* test(artifacts): use the shared comparison fixture for UnityFS

The UnityFS comparison test arrived from the bottom branch with its own
copy of the open_binary, inspect_artifact and compare_artifacts steps,
which tests/fixtures/artifactComparisonMcp.ts owns here. It now uses
connectArtifactComparisonMcp() like the other comparison acceptance
tests. No assertion changes.

* test(artifacts): find the contract's compared kinds by marker

The docs conformance test found its paragraph by an exact English phrase,
so rewording "also compares" failed it while the named kinds stayed
right. The paragraph now sits between BEGIN and END markers, as the
allocation report's sections do, and the test reads the kinds between
them. It still requires exactly the kinds whose table entry has a
declaration.

Entrpiandrobotaro 1df7ac9320 fix(ghidra): update the host no-return probe for the current bridge (#8462)
The host no-return verifier, scripts/verify-real-ghidra-noreturn.mjs,
fails before its Evidence checks. ReaNoReturnProbe calls private bridge
methods through reflection, and two bridge changes left the probe behind:

- d4bd65c53 added a Function parameter to noReturnCallLimitations, and
  225f26a5f renamed the method to functionBoundaryLimitations. The probe
  still looked up noReturnCallLimitations(Iterable) and stopped with
  NoSuchMethodException.
- 01a1b3fda made procedureReferences return a function observation
  envelope. The probe read references and unresolved_calls from the top
  level of that envelope instead of from its value.

Pass each function and its instructions to functionBoundaryLimitations,
and read procedureReferences results from the envelope value. The require
checks are unchanged. CI does not run this verifier.

These edits are the probe repair from robotaro's open draft that treats
demangled C++ runtime imports as returning, copied line for line, so
either change merges cleanly after the other.

Entrpiandmorluto b43c329df7 feat(artifacts): inventory and extract UF2 and DfuSe firmware containers (#8230)
* feat(artifacts): inventory and extract UF2 and DfuSe regions

open_binary refused UF2 and DfuSe firmware containers as an unsupported
format, so inspect_artifact and extract_artifact could not show which
bytes a drag-and-drop or DFU update writes at which addresses.

UF2 is recognized by a complete first block with all three magic
numbers. Valid main-flash payloads are joined into address-contiguous
regions per familyID, named family-0x<id>/0x<start>-0x<end>.bin, and
known IDs are named from a small table copied from Microsoft's
uf2families.json at a pinned commit. Numbering is counted per familyID
and block count: absent, repeated, out-of-order and out-of-range block
numbers are reported, and absent blocks leave coverage unknown.
Not-main-flash blocks are excluded and reported; file-container blocks
are reported and leave coverage unknown; invalid blocks and a partial
final block are excluded with their position. A rewrite of one address
with different bytes fails closed, naming both block spans.

DfuSe is recognized only by its prefix together with a DFU 1.1a suffix.
Each element becomes one region at its file range with its target's
alternate setting and name. Structural faults fail closed with a byte
offset; overlapping elements stay separate and are reported. A suffix
CRC mismatch follows integrity_policy: fail refuses with a dfu-crc32
integrity error, and record-and-continue records a root contradiction
that extraction also carries.

HEX, UF2 and DfuSe share one retained-region reader and one run
merger, so the HEX decoder and reader lose their private copies.

* docs(artifacts): document UF2 and DfuSe images and their esptool lane

Describe recognition, region names, metadata, numbering, failures, the
DfuSe suffix CRC under integrity_policy, and limits, and link the page
from the CLI and firmware guides and the agent skill reference.

npm run verify:uf2 runs esptool merge-bin --format uf2 on generated
inputs at known addresses, with and without MD5, with 256-byte
payloads, and on a concatenation of two chips' outputs. Inspection and
extraction through the built CLI must return every input at its address
under the familyID esptool itself reports.

* fix(artifacts): accept both DfuSe image size conventions

UM0391 calls DFUImageSize the file length, and dfu-util's dfuse-pack.py
writes that value, while ST's DfuFileMgr, MicroPython's dfu.py and pydfu
leave the 16-byte suffix out. The decoder accepted only the second form,
so it refused dfuse-pack.py output as malformed.

Accept either value and keep the declared one in image_size; any other
value still fails with the suffix offset and the file length. The tests
pin both producers' output for one image, CRC included, from their
build() functions transcribed and run under Python 3.

* fix(artifacts): keep reused UF2 block numbers from hiding missing blocks

esptool numbers every merged input from 0, so two inputs with the same
block count share one numbering group. A block lost from one input left
its number present in the other, and the file reported complete
coverage. Each block number now records the target addresses it was
seen at: equal address counts are complete copies, a resend to the same
address is one block, and unequal counts make coverage unknown with a
limitation and ambiguous_numbering_group_count. sequence_count becomes
numbering_group_count, and region block positions become
first_file_block and last_file_block.

Review follow-ups in the same change:
- compare_artifacts compares a DfuSe element's alternate setting and
  target name, so bytes moved to another device memory are changed;
- the shared reader keeps no region bytes outside its map after close;
- one domain type replaces four identical decoder failure types;
- the UF2 decoder returns a typed limit instead of throwing on bytes
  beyond its admitted size, and caps retained regions, not runs;
- DfuSe caps elements with bytes only, names empty elements and
  element-less targets, drops the constant bVersion and bcdDFU fields,
  and says whether the CRC matches when DFUImageSize fits neither
  convention;
- classification evidence carries a suffix only when the probe saw the
  end, and root classification reads the tail only for a DfuSe prefix;
- the UF2 domain region owns family_name, and the root records the
  family registry revision; the table's MIT notice is preserved;
- docs pin the producer revisions (dfu-util ee6b393d and f9a537c9,
  MicroPython cb99ca98), give the MD5 structure's real meaning, and
  describe container contradictions in the MCP contract guide;
- tests and the esptool lane add the equal-count inputs and a block
  lost from one of them, accepted boundaries beside each refusal, a
  DfuSe root larger than the classification prefix, and CLI refusals.

* feat(artifacts): name the UF2 families that LibreTiny builds for

LibreTiny writes UF2 for Realtek, Beken and Bouffalo Lab modules. The
Microsoft registry revision REA already cites (cf3bd7f9) lists eight of
those families: RTL8710A, RTL8710B, RTL8720C, RTL8720D, BK7231U, BK7231N,
BK7251 and BL602. Their regions now carry those names. LN882H, which
that revision omits, keeps its familyID with no name.

* fix(artifacts): count DfuSe declarations without bytes instead of listing them

Empty DfuSe elements have no entry, so DFUSE_MAX_ELEMENTS does not cap
them, and the target walk kept a description string for each one. At 8
bytes per element, a file under the 128 MiB ceiling can declare about
16.7 million of them. The walk now counts every declaration without bytes
and builds only the first NAMED_ELEMENTS descriptions, which is all that
the limitation shows. The limitation text and empty_element_count do not
change. The guide now says that both DfuSe limitations name the first four.

On this host, decoding 4,000,000 empty elements (a 32 MB file) ran out of
memory under a 128 MB V8 heap before this change, and it peaked at 1.59 GB
RSS with the default heap. It now decodes in 114 ms with a 220 MB peak.

Entrpi e669365c3b feat(ghidra): admit RISC-V ilp32 ELF with a derived calling convention (#8229)
* feat(ghidra): record the RISC-V float-ABI calling-convention decision

Decision D3 (#7477), provisional: admit ELF32 soft-float (ilp32) RISC-V
images through a lane that keeps the pinned RISCV:LE:32:default language and
corrects the calling convention in the bridge.

This commit is the contract only; admission is unchanged.

- The domain owns the e_flags float-ABI vocabulary and parses
  .riscv.attributes and Tag_RISCV_arch into a declared, absent or
  unavailable ISA declaration.
- The Ghidra profile owns the lane table (class and float ABI), lane ids
  built from fields, the ilp32-prototype-v1 policy and its __rea_ilp32
  prototype, and the extensions Ghidra 12.1.4 decodes with p-code.
- The session handshake accepts the bridge's calling-convention report.
- docs/ghidra-riscv.md keeps the decision record and per-ABI policies for
  ilp32 and ilp32f; a test keeps it in step with the tables.
- tests/conformance/c/riscv-float-abi.c is the source the policies were
  measured on.

* feat(ghidra): admit RISC-V ilp32 ELF with a derived calling convention

ESP32-C2, C3, C5, C6, C61, H2 and H21 builds are ELF32 soft-float (ilp32)
images, which the RISC-V lane refused at its double-float check. Ghidra
12.1.4's generic RV32 compiler specification models ilp32d, so its stock
prototype would read float and double arguments from fa0-fa7.

- Target resolution reads the one SHT_RISCV_ATTRIBUTES section through the
  same bounded ELF declaration reader as range validation, and records
  Tag_RISCV_arch as declared, absent or unavailable.
- Admission selects a lane from the class and float-ABI table. The soft-float
  lane also requires an RV32I Tag_RISCV_arch that declares only extensions
  Ghidra decodes with p-code; the refusal names any others (Zcb, Zcmp, Zcmt,
  Zb*, xesp*).
- Soft-float profiles commit float_abi, arch, riscv_calling_convention
  ilp32-prototype-v1 and the lane elf32-exec-le-soft-float-generic-v1.
  Double-float profiles are unchanged.
- ReaGhidraRiscvCallingConvention.java runs after analysis. It derives
  __rea_ilp32 from the default prototype without floating-point entries and
  rules, with fs0-fs11 killed by calls, self-checks its storage and assigns
  it to every non-thunk function, external function and function
  definition. Its report is written last.
- The provider client requires that report exactly when the profile commits
  the policy, before any operation, and keeps it as session limitations and
  caller-project history.

ELF32 single-float (ilp32f), quad-float and ELF64 soft- or single-float
images stay refused, now with a reason built from the lane table.

* test(ghidra): verify RISC-V ilp32 against real Ghidra

verify:ghidra:riscv now also builds tests/conformance/c/riscv-float-abi.c
with ESP32-C3's -march=rv32imc_zicsr_zifencei -mabi=ilp32, typed with DWARF
and linked again with --strip-all. Every allocated section of the stripped
image must keep its address and bytes.

- riscv-checks.mjs holds the ilp32 storage of each fixture function together
  with the words the compiler's call site writes there. An LLVM objdump
  reading of the caller must find every word at its stated location: an
  unaligned named double, the a7/stack split, two floats in an integer pair,
  a large structure by reference, aligned variadic pairs and an indirect
  call.
- Through CLI and stdio MCP, the soft-float builds must report the soft-float
  lane and ilp32-prototype-v1, __rea_ilp32 with exactly that storage (one
  integer word per location when stripped), caller pseudocode that passes the
  source constants and names no floating-point register, the prototype
  outcome in retained Evidence, and decoded fence.i and csrr.
- The RV32 double-float image relabelled as soft-float, refused before, is
  admitted through the new lane. RV64 soft-float, single-float and unsupported
  bits are refused with their reasons.
- riscv-checks.test.ts runs the checks offline against recorded LLVM and
  Ghidra output, including Ghidra's stock ilp32d prototypes as a negative
  control.

* fix(ghidra): pass RISC-V ilp32 values over 8 bytes by reference

The psABI passes any value wider than 2 x XLEN by reference, scalars
included. __rea_ilp32 converted only structures and unions over 8 bytes to
pointers, so a long double (16 bytes) was joined into a1-a4. Measured on
Ghidra 12.1.4, rea_riscv_abi_quad(long double value, int sel) read value
from a4:4,a3:4,a2:4,a1:4 and sel from a5, where clang passes a pointer in
a1 and sel in a2.

- ReaGhidraRiscvCallingConvention.java now has one derivation driven by a
  per-policy row (floating-point entry size, preserved floating-point
  registers). Every policy inserts a rule before the input list's final
  join that converts any value of 9 bytes or more to a pointer; a return
  that size already becomes a caller buffer. The self-check requires a
  16-byte value to pass by reference.
- The fixture gains rea_riscv_abi_quad. The call-site oracle now checks the
  words the by-reference pointers point at, for the large structure and the
  long double, and the recorded data comes from an LLVM 19 build.
- docs/ghidra-riscv.md: the decision record and the ilp32 policy row.

ilp32-prototype-v1 keeps its id: no release carries it yet.

* test(ghidra): check RISC-V lane limitations by their facts

The limitation tests froze a full explanatory sentence, the note count and
array positions, so a harmless rewording failed them: the pattern Greptile
flagged on #7486. Assert the facts the notes must carry instead: the pinned
language, the static-linkage boundary, one note naming the declared ABI,
the ABI the pinned language models and the prototype REA applies, and the
declared ISA.

* test(ghidra): check return storage in stripped RISC-V ilp32 builds

The stripped branch of assertRiscvIlp32Storage compared parameter storage
only, so an inferred return that lost the high word of a register pair,
such as rea_riscv_abi_wide at a0:4 instead of a1:4,a0:4, still passed.

Stripped returns must now use the typed build's storage, or none when the
result goes through caller memory. Recovered type names are still not
compared: a test accepts other type names and refuses the dropped high word.

Entrpi e6d0618979 feat(artifacts): inventory and extract ESP flash layouts (#8228)
* feat(artifacts): inventory and extract ESP32 firmware images

ESP32-family app and bootloader images (magic 0xE9) had no reader, so
open_binary refused OTA downloads, app partitions and bootloaders.

Add the esp-image container format behind inspect_artifact and
extract_artifact. A pure decoder reads each byte once and keeps only
fixed-size fields. Derived facts cover the chip, from a table cited to
ESP-IDF v6.1; segment classification as ESP-IDF's should_map and
should_load; checksum and appended SHA-256 results; app and bootloader
descriptors; Secure Boot v2 signature blocks, observed and unverified;
and undescribed trailing byte ranges. Truncation and undescribed bytes
make coverage unknown. ESP8266 images are refused with a specific
reason, and ciphertext stays unrecognized.

Add the format to every target, Evidence, snapshot, live-summary and
artifact vocabulary, document it, and add an optional verify:esp-images
lane that compares esptool-built images with esptool image-info and
espsecure signature-info-v2.

Refs #3615

* test(artifacts): run the ESP image lane on esptool v5.6.0

The lane compared descriptor fields only when esptool image-info printed
one, so a descriptor that REA reports and esptool does not print passed
without comparison. Compare the descriptor kind in both directions.

Record that the lane passed for all 13 images with esptool and espsecure
v5.6.0, the version the layout facts cite, as well as with 4.12.0.

* refactor(artifacts): define ESP image layout sizes once

The decoder and the derived facts each defined the segment-header,
appended-digest and flash-sector sizes, the erased-byte scan and the
offset formatter. Define them once with the other fixed-layout structures
and import them in both places. The signature slot count is the one
constant that drives the slot scan.

Correct the observedEnd comment: it is the end of the last chunk read.

* fix(artifacts): report ESP-IDF's segment length limit by chip

ESP-IDF's verify_segment_header rejects a segment of 16 MiB or more
unless the chip maps flash through 32-bit cache addresses
(SOC_SPI_MEM_SUPPORT_CACHE_32BIT_ADDR_MAP: ESP32-S3, P4, C5, C61, H4 and
S31 in v6.1). Record that capability in the chip table and add a
limitation for such segments; unknown chips get none.

`loaded` repeats should_load. It does not mean the bootloader accepts the
segment: verify_load_addresses still rejects one outside the chip's RAM,
which REA does not model. Say so in the docs, the skill reference and the
inventory limitation.

* test(artifacts): check ESP lane tools first and verify extraction

The lane started work before checking its tools, so a missing RISC-V
target, ld.lld, esptool or espsecure surfaced as a raw spawn or command
error. Check each one before building and name the variable to set. Warn
when esptool is not v5.6.0, the release the layout facts cite.

Assert each segment's class for the ESP32-C3 app, its variants and the
bootloader, as the Xtensa image already did. Extract the app and the
signed image through the CLI and compare every file with the bytes at
esptool's segment offsets or in the appended signature sector; the
source's SHA-256 must be unchanged and equal the reported root_sha256.

* docs(artifacts): state what the ESP image lane does not establish

The Verification section listed the lane's checks but not its gaps: only
ESP32-C3 and ESP32 images come from a real producer, no real project
build, OTA download or flash dump is inspected, no signature is verified,
and the lane does not run in CI.

Record the timing of the final lane run on esptool v5.6.0.

* fix(artifacts): compare ESP segment declarations

Segment entries hash only their data, so compare_artifacts reported a
segment that moved to another load address with the same bytes as
unchanged; only the image itself changed. Compare each segment's
load_addr and data_len as its declaration, as Node SEA and PyInstaller
members are compared, and count a changed declaration as a metadata
change, also when content is unavailable.

Header offsets are layout and the classification is derived, so neither
is compared.

* test(artifacts): run ESP lane commands as owned process trees

The lane ran its tools through execFile. A timeout killed only the direct
child, so a linker or assembler that Clang or GCC had started could keep
running while the lane removed its workspace. Run every command through
createVerifierCommands, check the tools inside withVerifierCleanup, and
remove the workspace only after commands.close() has stopped every tree;
a failed close keeps the workspace.

Only a nonzero exit now counts as a refusal or an expected esptool
failure; timeouts and spawn failures propagate. Supervising each command
roughly doubles the lane's run time.

* test(artifacts): cancel ESP decoding after its first decoded chunk

The cancellation test requested cancel or close on setImmediate, which
can land while the file is still being opened and checked, so it never
showed that decoding had started. It also passed against a reader that
ignored both requests while decoding. Acknowledge the decoder's first
chunk, then cancel or close, join the operation, and assert that no
later chunk reaches the decoder and that the reader ends closed.

* docs(artifacts): record which ESP metadata comparison ignores

Segments are compared by their declaration. The image's and the
signature blocks' format_metadata are not: every field comes from their
own bytes, which content comparison already covers, and a block's
image_digest_matches follows the image's content.

* feat(artifacts): inventory and extract ESP flash layouts

A whole-flash dump of an ESP32-family chip was read as its bootloader
image, with the partition table, apps and data left as undescribed bytes,
or refused when it began with erased flash. Read it as an esp-flash-image
container instead.

The partition table is decoded as esp_partition_table_verify accepts it
and is found at the caller's partition_table_offset, at the default
0x8000, or by scanning 0x1000-aligned sectors for a table whose MD5
verifies, which the inventory reports as derived. The bootloader is
located at its chip's ROM bootloader offset. Each partition is an entry
with its declaration in flat format_metadata; the bootloader and app
partitions carry ESP image facts from the existing streaming decoder; the
otadata records are reported with a selection derived without rollback or
anti-rollback, and the running partition stays unknown. One unreadable
partition does not hide the others, and extraction writes every partition,
nvs_keys included, as ordinary data.

Flash layouts are detected before single ESP images. The scan runs only
when an ESP image sits at a ROM bootloader offset, and is refused when a
bootloader at another chip's offset shows that the dump does not start at
flash address 0. open_binary gains flash_offset and partition_table_offset,
which require format esp-flash-image and are part of the snapshot target
identity; the CLI takes them with --target-format esp-flash-image.
Comparison treats a partition's label, type, subtype, range and flags as
its declaration.

* test(artifacts): verify ESP flash layouts with gen_esp32part, merge-bin and otatool

Add the optional verify:esp-flash lane. It builds default and relocated
partition tables with ESP-IDF's gen_esp32part.py, assembles dumps with
esptool merge-bin, including one written from flash 0x1000, and writes
OTA records with otatool through flash_file_tool.py, which replaces
parttool's esptool calls with reads and writes of the dump file.

It compares REA's bootloader and app facts with esptool image-info, every
partition with gen_esp32part.py's decoding of the extracted table, and the
OTA records and derived slot with otatool read_otadata after each switch.
It also checks extracted bytes and source integrity, the scan and caller
table offsets, flash_offset on the 0x1000 dump, a corrupted app beside
valid partitions and a truncated dump. ESP32 linker scripts place the
conformance bootloader and app in ESP32 address ranges.

* fix(artifacts): read ESP flash layouts as the bootloader does

Read the partition table as bootloader_utility_load_partition_table
does: the last factory, otadata and same-subtype OTA declaration wins,
and a limitation names repeats. Plan each otadata record within its
partition and the dump. An otadata partition smaller than two sectors
selects none, the bootloader's INVALID_INDEX; a record the dump lacks
leaves the selection unknown while the other record stays reported. The
fallbacks follow the bootloader's indexes: ota_0-fallback and
factory-fallback name no partition when the table declares none, and the
assumptions add GPIO holds and deep-sleep wake.

Refuse a dump whose bootloader contradicts its origin before the default
table offset is tried, whether flash_offset was omitted or given, and keep
the ESP image reader's ESP8266 refusal. A table never lies inside the
located bootloader image, so single app images are no longer scanned. An
explicit esp-flash-image selection is decided before other container
signatures, and the native commands' --target-format no longer takes it.
Say when no bootloader confirms the default origin.

Exempt the primary bootloader and partition_table entries of ESP-IDF 5.3
from placement limits, report every region inside a longer one, and name
partitions by index when labels repeat ignoring case. Keep an undecodable
label's bytes in label_hex and compare them. Word undescribed ranges as
starting at a byte that is not erased, and treat a short erased region as
erased.

Add an MCP compare_artifacts test for partition declarations, reader
identity and close tests, scan edge cases, the 0x2000 ROM offset and a
literal otatool CRC.

* test(artifacts): verify ESP primary layout entries and the otadata fallback

Build a table with the primary bootloader and partition_table entries
that gen_esp32part.py fills from --primary-bootloader-offset, and check
that REA reads it with complete coverage, no overlap or misplacement
limitation, and a table that agrees with gen_esp32part's decoding. Erase
the otadata with otatool after the slot switches and check the records
against read_otadata and the factory fallback.

* fix(artifacts): keep ESP flash coverage complete for a dump cut short

An esptool merge-bin dump ends after the last part it wrote, usually inside
its last partition. Such a partition made the layout's coverage unknown, so
artifact comparison of two merge-bin dumps reported every unchanged
partition as unknown.

The partition table names every partition whatever the file's length, so a
partition cut short or left out by the end of the file hides no entry. As
the ESP image reader does for a cut-short segment, its entry holds the bytes
the file has and an entry limitation gives the declared size; a partition
with no bytes stays in partitions_outside_dump. Coverage stays complete
unless undescribed bytes remain or no bootloader is located. An MCP
compare_artifacts test of two dumps that end inside ota_0 now classifies
every partition, and fails on the old rule.

* fix(artifacts): report written bytes in ESP partitions, erased slots included

An app slot is erased for ESP-IDF's bootloader when its image header bytes
are erased flash, and REA reported only that status. A slot can still hold
data further in: a dump read from a device held a complete older app image
1 MiB into an OTA slot reported as erased, with no limitation.

Each partition entry now records where the bytes the dump holds are
written, relative to the partition: written_offset, the first byte that is
not 0xFF, written_end, just past the last, and written_bytes, how many are
not 0xFF. They are null for a partition outside the dump. The status stays
erased, which is the bootloader's view, and a limitation names an erased
app slot that holds written bytes and says they are not read as an image.
The reader reads every partition byte once more to find them.

* fix(artifacts): derive the ESP boot selection for every partition table

The boot selection lived inside otadata, so a table without an otadata
partition, the common factory-only layout, had none. ESP-IDF's
bootloader_utility_get_selected_boot_partition returns the factory index
when the table declares no otadata partition.

Move it to a top-level boot_selection that every layout has. Its basis
names the bootloader's branch: otadata, factory-fallback and ota_0-fallback
from the records, no-otadata for a table without otadata, none for the
bootloader's INVALID_INDEX, and unknown when the dump lacks a record the
bootloader reads, which replaces the null selection. running_partition
moves with it, and otadata keeps its partition index and records. The
assumptions name what each branch leaves out: no records assumption
without otadata, and none for none or unknown. The real-tool lane checks
no-otadata on a table gen_esp32part built without otadata.

* fix(artifacts): say when an ESP image is a flash dump read from 0x1000

An ESP32 dump read from flash 0x1000, as read-flash 0x1000 or merge-bin
--target-offset 0x1000 writes it, opened automatically as its bootloader
image with a megabyte of undescribed bytes and no next probe. The flash
reader refuses that origin, but nothing told an agent which flash_offset to
pass.

espFlashDumpOrigin owns the inference: an image of a chip whose ROM loads
the bootloader from flash R, at file offset F, is the bootloader of a dump
read from R - F when a partition table sits where that origin puts 0x8000.
The ESP image reader asks it for a non-app image at file offset 0, so the
result does not depend on how the reader was created, and records
flash_dump {flash_offset, table_file_offset}, null otherwise, with a
limitation that says to reopen the file as esp-flash-image with that
flash_offset. inspect_artifact proposes the same open_binary call as a next
probe, and the flash reader's misplaced-origin refusal names the offset.

* perf(artifacts): summarize nested ESP images in the flash layout summary view

The summary view returned an ESP flash layout's root facts whole, so each
app partition and the bootloader carried every segment and signature
block, about half of a dump's summary.

The summary view now gives each nested image a summary instead of its
facts: status, chip, entry point, segment count, load ranges (each mapped,
loaded or unclassified segment's address and declared length), the
checksum and appended SHA-256 statuses, coverage and limitations. Complete
detail keeps the full facts, every segment included, and the retained
Evidence is unchanged. On a 16 MiB device dump the summary's root falls
from 5,141 to 2,657 bytes, and the summary Evidence from 10,038 to 7,554.

* test(artifacts): expect the misplaced image the ESP bootloader search reports

8a748d3cc added misplacedImage to the bootloader search, which the
locator uses to name the origin a misplaced bootloader implies, but one
test still compared the search result without it. Expect the image's
chip and file offset, and no image for an unknown chip.

* fix(artifacts): give every ESP partition from the dump's start an entry

After ecbc1a772 kept coverage complete for a dump cut short, a partition
wholly past the end of the file still had no entry, only a
partitions_outside_dump row. Comparing a merge-bin dump with a full device
read then reported that partition as added or removed, as if one table
did not declare it.

Every partition from the dump's first byte on is now an entry holding the
bytes the file has: none for one past the end, with a limitation saying
the file holds none of its bytes, no image facts and null written fields.
partitions_outside_dump keeps only partitions that begin before the dump's
first byte, and coverage is unknown when one does, since it has no entry.
Two dumps that lack the same partition now compare it as unchanged, and a
dump against a longer one reports the partition as changed; an MCP test
of a merge-bin dump against a full one checks that no path is added or
removed.

Unlike the ESP image reader, which marks a truncated image's coverage
unknown because later segments and signature blocks may be hidden, the
flash reader can list every partition from the table whatever the file's
length; only the entry limitation follows the image reader.

* fix(artifacts): select no ESP app from a partition table the bootloader rejects

boot_selection followed bootloader_utility_get_selected_boot_partition but
not the table check before it. For a table whose MD5 does not match, or
that has a second MD5 entry, esp_partition_table_verify fails, the
bootloader selects no app and resets. REA still derived a slot from the
otadata records, although the table's own limitation said the bootloader
rejects it.

The selection now has basis none, with no assumptions, for a table the
decoder marks invalid. It also follows two more branches of the
bootloader: an otadata partition at offset 0, which the bootloader takes
for none, selects the factory index as no-otadata, and a table without an
OTA app selects its fallback even when the dump lacks a record, since the
bootloader then ignores the records.

The bootloader also rejects a table whose partitions end past the flash
size in its header. REA does not model that check; the format guide says
so.

* fix(artifacts): require the ESP dump origin's table to follow the image

espFlashDumpOrigin named a later flash origin whenever a partition table
decoded where that origin puts 0x8000. Bytes inside the image's own
segments could be read that way, so an ESP32 bootloader whose segment data
held table-shaped bytes at file offset 0x7000 was reported as a dump read
from 0x1000.

The table must now start at or after the image's end, the rule the locator
already applies to the default table. The ESP image reader passes the
image_end it decoded, or the file size for a truncated image; the flash
reader's refusal passes the end of the misplaced image's segments. The
bootloader search drops its misplaced flag, which only restated
misplacedImage, and the next probe formats offsets with offsetText.

Reader tests cover the 0x1000 and 0x2000 ROM offsets, a standalone
bootloader, bytes that begin like a table, an app with a table at 0x7000
and a table inside a segment; without the boundary check, three of them
fail.

* fix(artifacts): give the ESP flash summary its own kind and each image's identity

The summary view's ESP flash root kept kind esp-flash-image, so a consumer
bound to kind could not tell an image's summary from its full facts, and
the advertised schema held two objects with the same kind const. It is now
esp-flash-image-summary.

The per-image summary also dropped the descriptor, which is what tells two
app slots apart, and named each image only by its partition index, which
the summary view, having no entry rows, could not resolve. Each nested
image now carries its entry path from the layout plan, in both views. The
summary adds the descriptor kind with its identifying fields (an app's
project_name, version, idf_ver, secure_version and app_elf_sha256; a
bootloader's version, idf_ver and secure_version), the signature block
count and each load range's classification. Its enums and fields derive
from the schemas that own them.

An MCP test reads a dump with an app in ota_0 and an erased ota_1 that
holds older bytes: it checks both summaries, that the summary's inventory
Evidence is the one the complete view returns with full facts, and the
erased slot's written range.

* test(artifacts): cover cancel and close during the ESP written-bytes scan

The written-bytes pass reads every byte of each partition the dump holds,
checking that the reader is open before each chunk, but only app decoding
had a cancellation and close test. A data partition, which only that pass
reads, now holds 9 MiB; once the scan has examined its first chunk, a
cancel rejects preparation with the caller's reason and a close with
unavailable, and the scan examines no further chunk.

The erased-slot test now asserts the whole set of erased-slot limitations,
so factory, ota_0 and nvs, which the bootloader reads or which are not app
slots, are shown to have none.

* docs(artifacts): re-time the ESP flash lane and state only observed causes

The lane ran again after its assertions changed; both esptool runs passed,
and the timed run's figures replace the earlier ones. The erased-slot
paragraph no longer names a cause for the older bytes, which REA cannot
observe, and the skill reference states that every table has a
boot_selection in its own sentence, with the none basis for a table the
bootloader rejects.

* fix(artifacts): retire ESP flash members as the ESP image reader does

#7498's maintainer commits made the ESP image reader keep a member owned
until its consumer closes it, retire fully buffered bytes when
cancellation arrives after production, and refuse to finish an inventory
paused across close. The ESP flash reader was copied from the earlier
reader. Main's shared stored-member lifecycle cases failed two of eight
against it: a paused inventory completed after close, and buffered member
bytes stayed readable after cancellation.

Give the flash reader the same lifecycle and run the shared cases against
it.

* docs(artifacts): re-time the ESP flash lane after merging main

The lane passed again with esptool v5.6.0 and 4.12.0 on the merge of upstream main. Record the v5.6.0 run's time and peak resident set.

* fix(artifacts): read ESP image Evidence recorded before flash_dump

The flash layout work made `flash_dump` a required field of the
`esp-image` root metadata. Evidence recorded before it has no such
field, so newer REA rejected records that were valid when they were
made: `compare_artifacts` and `inspect_analysis_view` reported
`evidence_integrity_mismatch` for them.

The field is now optional when read. A record without it parses as it
is, so the graph digest it commits to still matches; nothing fills the
field in. The image reader still writes it for every image, and the
inspection probe reads a missing field as no hint.

A regression test recommits an image inventory without the field and
passes it inline to `compare_artifacts` and `inspect_analysis_view`.
Against a server built with the required field, `compare_artifacts`
rejects it.

* fix(artifacts): stop the ESP flash gap scan when the reader closes

The scan for the first written byte in each undescribed gap checked
only the caller's signal. `close()` marks the reader closed and waits
for preparation, so it waited while the rest of a long erased gap was
read.

The gap scan now takes the reader's open check, as the written-bytes
scan and the image decoder do, and checks it before each chunk. Tests
cancel or close the reader after the scan's first chunk of a 9 MiB
erased gap and confirm that no later chunk is examined.

* fix(artifacts): name ESP partitions with Windows device labels by index

The safe-label rule accepted labels such as `NUL`, `con` or `COM1`, so
extraction wrote `partitions/NUL.bin`. Windows reserves those names
before any extension, and ordinary Windows tools cannot use such a
file.

A label that is a Windows device name (`CON`, `PRN`, `AUX`, `NUL`,
`COM0`-`COM9` and `LPT0`-`LPT9`, any case, alone or before a dot) now
takes the existing index fallback. The partition metadata and the
entry's source path keep the label.

* fix(artifacts): read ESP flash partitions' written bytes in one pass

Each partition got its own scan of the bytes the dump holds, so
partitions declared over the same bytes read them again and again.
Overlaps only add limitations, so a crafted table reached this normally:
94 overlapping partitions over a 32 MiB dump would examine about 3 GiB
before the first entry.

The reader now reads the bytes the partitions cover once. Partition
boundaries cut them into segments; one pass counts each segment's
written bytes and bounds, and each partition's extent is the sum of the
segments inside it. Every partition keeps its own declaration, extent
and limitations. The pass checks the reader's open state before each
chunk, as the per-partition scan did.

A test declares 60 partitions over one MiB, 40 over all of it and 20
over its first half, and checks each partition's extent and the
overlap limitations. The reader reads 1,113,256 bytes of the
1,114,112-byte dump; one scan per partition read 52,493,480.

* test(artifacts): fail the ESP lanes on failed commands and refusals

`otatool` turned a nonzero exit into returned text, which its callers
discarded, and `inspect()` returned `{ refused }`, which the flash lane
never checked. A failed command then surfaced later as a slot
assertion, an output-parser error or a TypeError, hiding its cause.

Commands the lanes need to succeed now reject with the output they
exited with: `otatool` and `inspect()` do so through a shared
`failedCommand`. An expected refusal is opt-in: `refusal()` returns
REA's output and fails the lane when REA opens the file. The ESP image
lane's two ESP8266 cases use it.

Checked by calling `otatool` on a file without a table, `inspect()` on a
file REA refuses and `refusal()` on a file REA opens; each rejects with
its cause.

* fix(artifacts): require a partition entry in an ESP partition table

The decoder counted the slot, not the partitions, so a lone MD5 entry
over the empty prefix, followed by the terminator, decoded as a table
with no partitions. Default and caller-selected detection then accepted
that empty layout, although the guide requires one partition.

A table now needs one partition entry before its terminator. An MD5
entry alone is refused as `entry 1 at 0x20 ends the table before any
partition entry`. The cases cover the decoder and both automatic and
caller-selected location.

* fix(artifacts): decode an image shared by ESP app partitions once

Each app partition got its own decode, so app partitions declared over
the same bytes decoded and hashed the same image again and again, the
same pattern the written-bytes scan had. With 60 app partitions over
one 960 KiB image the reader read 64,029,736 bytes of a 1,114,112-byte
dump.

Regions with the same file range now share one decode; each keeps its
own copy of the facts. Partitions with different ranges still decode
separately, because truncation can change the facts: at most one decode
per partition the table holds, each within its partition.

A test declares 60 app partitions over one image, 40 holding all of it
and 20 cutting it short, and expects three decodes: the bootloader, the
whole image and the cut one. The 60-partition dump now reads
2,161,864 bytes, as a dump with one app partition does.

Entrpi 091892dfed test(ghidra): expect carved MIPS copies to be refused at target opening (#8227)
Since 651afa445 target opening refuses every ELF declaration beyond EOF,
including carved copies, and ac6e0e258 moved the carved MIPS boundary tests
to that contract. The real-Ghidra MIPS lane still expected a carved image to
resolve with section-table limitations and be refused later by Ghidra
admission, so verify:ghidra:mips failed at its first carved fixture.

The lane now requires open_binary and the CLI to refuse the carved copy as
target_unavailable (file_format_rejected) with the exact declared
section-table range and captured size. The carve and that expectation live in
the shared MIPS checks, and a boundary regression applies them to the
production resolver and error projection, so a later contract change fails
without real Ghidra. The MIPS and PSP guides describe the current contract.

Entrpi 250dc81cd6 fix: correct stale provider refusal and diagnostic text (#7484)
* fix(ghidra): name every admitted family in the architecture refusal

The refusal listed x86, x86_64, arm, arm64, MIPS, RISC-V, raw 6502 and
raw m68k, but the admission set also holds powerpc and hexagon. Build
the text from SUPPORTED_ARCHITECTURES, marking raw-only families, so a
newly admitted family cannot be left out again, and name the refused
family.

* fix(hopper): stop calling the Ghidra Hexagon lane verified

Hopper declined Hexagon targets with "Select a verified Ghidra Hexagon
profile instead", but REA has no verified Hexagon lane. Record whether
each declined family's Ghidra lane is verified, and say that Ghidra
admits Hexagon through an unverified lane.

Name declined families by architecture id, as the Ghidra and IDA
refusals do.

* fix(ghidra): name the pinned language in profile readback refusals

The session readback said "MIPS" whenever a provider-pinned profile
conflicted with the target or with REA_GHIDRA_LANGUAGE_ID, although the
RISC-V, PowerPC and DOL lanes are pinned too. The readback helper was
MIPS-named and re-parsed the language slot that
ghidraProfileLanguageOverride already owns. Move it beside that owner as
a family-neutral readback and name the pinned language id instead.

* fix(ghidra): list DOL among independently verified load images

GameCube DOL load images are independently verified, but the declined
format reason, the inspect_native_load_image capability note and the
Windows P0 guide listed only DOS MZ, DOS COM and raw-binary.

* fix(ghidra): count RV32E's sixteen integer registers

The EF_RISCV_RVE refusal described a 15-register ABI. RV32E has 16
integer registers, x0-x15, as docs/ghidra-riscv.md already says.

* fix(elf): name the refused e_machine

"unsupported ELF architecture" did not say which machine was refused.
Include the numeric e_machine, for example EM_XTENSA 94.

* test(hopper): assert declined-lane facts and owned refusal reasons

The MIPS case banned the phrase "not verified" instead of checking
facts, so wrong advice would still pass. Expose each declined family's
Ghidra lane status, assert those statuses, check that the advice depends
on the status, and compare Hopper's refusals with
hopperDeclinedArchitectureReason. The RISC-V refusal table now compares
the provider's reason with ghidraRiscvUnsupportedReason and expects the
EF_RISCV_RVE declaration name rather than fixed wording.

* test(ghidra): assert verified load-image formats as owned facts

The declined-format test required display phrases such as "DOS MZ" and
"GameCube DOL", so harmless rewording failed it while wrong guidance
containing those names passed. The format list was also spelled three
times: in the attestation's membership check, its reason and the
inspect_native_load_image capability note. Give the verified formats one
owner with the formatters for both texts, assert the list as a fact, and
compare the delivered reason and capability note with those formatters.

* fix(hopper): stop restating which Ghidra lanes REA has verified

Hopper's refusal for families it declines carried its own table of
which Ghidra lanes REA has verified (mips, riscv and powerpc verified,
hexagon not). That restated the Ghidra provider's facts in Hopper and
goes stale whenever they change, the drift that made the Hexagon refusal
wrong in the first place. Reading Ghidra's facts from Hopper would
couple the providers instead; no module in src/hopper imports from
src/ghidra.

The table and hopperDeclinedGhidraLane are removed.
hopperDeclinedArchitectureReason now states only what Hopper owns: it
does not admit the family, and the Ghidra provider's lane reports
whether REA has verified it. The arm64_32 sentence is unchanged.

The test checks every declined family against the formatter: each
reason names the family and Ghidra, and apart from the name all reasons
are the same text, so none states a per-family Ghidra status.

* fix(hopper): route declined families to Ghidra without promising its lane facts

The refusal said the Ghidra lane reports whether REA has verified it, but
Ghidra admits Hexagon with no such note, so a caller could not find the
promised status. Hopper now only states that it does not admit the family
and routes the caller to the Ghidra provider.

Entrpi 54756ff24e test: guard target format vocabularies and DOL snapshot saves (#7481)
* test(mcp): save and reopen a GameCube DOL snapshot

#7290 reported that DOL Evidence could not be bundled or saved; 50822e1ef
fixed the bundle manifest and added bundle export/import coverage, but no
test saved a DOL session through close_binary. Save a DOL snapshot with
recorded Evidence, check its target and artifact manifest, then reopen it
and replay the read without running the provider again.

* test(binary): require every target format in each target vocabulary

A new target format must be added by hand to the Evidence subject,
bundle manifest, snapshot target and live summary vocabularies; missing
one caused #7290. Give every BinaryTarget format a fixture through a
mapped type, so a new format fails compilation until it has one, and
push each fixture through the producers that persist or project targets.
Caller-selected format hints must name executable target formats.

This is a guard until target formats have a single owner.

* test(mcp): assert the replayed DOL result and the owned replay limitation

The DOL snapshot replay test checked the subject and the provider-call
count but not the answer, so a replay returning null or another value
would pass. Compare the replayed normalized result with the original.
Name the replay limitation as SNAPSHOT_REPLAY_LIMITATION in the snapshot
cache that adds it, and assert that value instead of repeating the
sentence.

* test: list Intel HEX and S-record targets in the vocabulary guard

Upstream added the intel-hex and srec formats (#7136). The guard requires
a fixture for every target format, so after merging main it no longer
typechecked; both formats now have archive fixtures and pass the same
persistence and projection checks.

* test: list UnityFS among the target format fixtures

Upstream #7699 added the unityfs target format, so the vocabulary test's
per-format fixtures must name it; without one the test no longer typechecks
against main.

* test: list uImage among the target format fixtures

Upstream #7234 added the uimage target format, so the vocabulary test's
per-format fixtures must name it; without one the test no longer typechecks
against main.

* test: list the ESP image among the target format fixtures

Upstream #7498 added the esp-image target format, so the vocabulary test's
per-format fixtures must name it; without one the test no longer typechecks
against main.

Entrpi 19ab239278 ci(ghidra): probe M-profile ARM and Xtensa decoding (#7482)
* ci(ghidra): probe M-profile ARM and Xtensa decoding

The embedded plan relies on ARM:LE:32:Cortex, ARM:LE:32:v8-m and
Xtensa:LE:32:default, but CI only exercised ARM:LE:32:v7. Import
source-owned bytes for each language at 0x1000 with -noanalysis and
check how they decode from the language's default context: Cortex and
v8-m must start in Thumb state, v8-m must decode the ARMv8-M MSPLIM
register, and Xtensa must decode entry and retw.n.

Add the probe scripts the job runs, including the existing ARM context
probe, to the ghidra_bridge change scope.

* ci(ghidra): match decode-probe operands as complete operands

The operand expectation searched the instruction text for a substring,
so mrs/4/msp also accepted mrs r0,msplim. Compare it with each operand
Ghidra reports for the instruction, so only a complete operand matches.
The Cortex (msp, lr), v8-M (msplim, lr) and Xtensa (a1) expectations are
unchanged.

Entrpi 1926fc2dac fix(ida): admit architecture families by allowlist (#7485)
IDA refused MIPS, RISC-V, PowerPC, Hexagon and arm64_32 by denylist, so
any family nobody excluded was reported supported, and the label ternary
printed "Hexagon" for any other metadata family. Admit exactly the
families IDA admits today (x86, x86_64, arm, arm64) and name every other
family from its own architecture id. Families that Ghidra admits keep
the pointer to a Ghidra profile.

Refusal text now uses architecture ids, for example "no verified mips
lane" instead of "no verified MIPS lane".

Entrpi b33f4a5a1b docs: correct the raw ARM example and document a Cortex-M language override (#7483)
* docs(raw-binary): replace the STM32-style ARM example

The headline raw example opened ecu.bin at 0x8000000, an STM32 flash
address, while the arm lane decodes in ARM state. Map a 32-bit ARM-state
image at 0x8000 instead, and state beside the example that Thumb-only
images, including Cortex-M firmware, are not supported.

* docs(ghidra): document an interim Cortex-M language override

Ghidra imports little-endian ARM ELF files as ARM:LE:32:v8, which
defaults to ARM state and marks Thumb code only from $t mapping symbols
and odd function-symbol addresses. Unpinned arm ELF already admits
REA_GHIDRA_LANGUAGE_ID, so document ARM:LE:32:Cortex (ARMv6-M, ARMv7-M,
ARMv7E-M) and ARM:LE:32:v8-m (ARMv8-M) as an unverified interim.

State the override's full effect while it is set: raw-binary, DOS, DOL,
PSP and language-pinned lanes such as RISC-V refuse it, and REA asks
Ghidra to import every other target in the ARM language, because it does
not check the override's processor against the target.

Entrpiandgensokyo-dev 64196b08ca feat(artifacts): inventory and extract ESP32 firmware images (#7498)
* feat(artifacts): inventory and extract ESP32 firmware images

ESP32-family app and bootloader images (magic 0xE9) had no reader, so
open_binary refused OTA downloads, app partitions and bootloaders.

Add the esp-image container format behind inspect_artifact and
extract_artifact. A pure decoder reads each byte once and keeps only
fixed-size fields. Derived facts cover the chip, from a table cited to
ESP-IDF v6.1; segment classification as ESP-IDF's should_map and
should_load; checksum and appended SHA-256 results; app and bootloader
descriptors; Secure Boot v2 signature blocks, observed and unverified;
and undescribed trailing byte ranges. Truncation and undescribed bytes
make coverage unknown. ESP8266 images are refused with a specific
reason, and ciphertext stays unrecognized.

Add the format to every target, Evidence, snapshot, live-summary and
artifact vocabulary, document it, and add an optional verify:esp-images
lane that compares esptool-built images with esptool image-info and
espsecure signature-info-v2.

Refs #3615

* test(artifacts): run the ESP image lane on esptool v5.6.0

The lane compared descriptor fields only when esptool image-info printed
one, so a descriptor that REA reports and esptool does not print passed
without comparison. Compare the descriptor kind in both directions.

Record that the lane passed for all 13 images with esptool and espsecure
v5.6.0, the version the layout facts cite, as well as with 4.12.0.

* refactor(artifacts): define ESP image layout sizes once

The decoder and the derived facts each defined the segment-header,
appended-digest and flash-sector sizes, the erased-byte scan and the
offset formatter. Define them once with the other fixed-layout structures
and import them in both places. The signature slot count is the one
constant that drives the slot scan.

Correct the observedEnd comment: it is the end of the last chunk read.

* fix(artifacts): report ESP-IDF's segment length limit by chip

ESP-IDF's verify_segment_header rejects a segment of 16 MiB or more
unless the chip maps flash through 32-bit cache addresses
(SOC_SPI_MEM_SUPPORT_CACHE_32BIT_ADDR_MAP: ESP32-S3, P4, C5, C61, H4 and
S31 in v6.1). Record that capability in the chip table and add a
limitation for such segments; unknown chips get none.

`loaded` repeats should_load. It does not mean the bootloader accepts the
segment: verify_load_addresses still rejects one outside the chip's RAM,
which REA does not model. Say so in the docs, the skill reference and the
inventory limitation.

* test(artifacts): check ESP lane tools first and verify extraction

The lane started work before checking its tools, so a missing RISC-V
target, ld.lld, esptool or espsecure surfaced as a raw spawn or command
error. Check each one before building and name the variable to set. Warn
when esptool is not v5.6.0, the release the layout facts cite.

Assert each segment's class for the ESP32-C3 app, its variants and the
bootloader, as the Xtensa image already did. Extract the app and the
signed image through the CLI and compare every file with the bytes at
esptool's segment offsets or in the appended signature sector; the
source's SHA-256 must be unchanged and equal the reported root_sha256.

* docs(artifacts): state what the ESP image lane does not establish

The Verification section listed the lane's checks but not its gaps: only
ESP32-C3 and ESP32 images come from a real producer, no real project
build, OTA download or flash dump is inspected, no signature is verified,
and the lane does not run in CI.

Record the timing of the final lane run on esptool v5.6.0.

* fix(artifacts): compare ESP segment declarations

Segment entries hash only their data, so compare_artifacts reported a
segment that moved to another load address with the same bytes as
unchanged; only the image itself changed. Compare each segment's
load_addr and data_len as its declaration, as Node SEA and PyInstaller
members are compared, and count a changed declaration as a metadata
change, also when content is unavailable.

Header offsets are layout and the classification is derived, so neither
is compared.

* test(artifacts): run ESP lane commands as owned process trees

The lane ran its tools through execFile. A timeout killed only the direct
child, so a linker or assembler that Clang or GCC had started could keep
running while the lane removed its workspace. Run every command through
createVerifierCommands, check the tools inside withVerifierCleanup, and
remove the workspace only after commands.close() has stopped every tree;
a failed close keeps the workspace.

Only a nonzero exit now counts as a refusal or an expected esptool
failure; timeouts and spawn failures propagate. Supervising each command
roughly doubles the lane's run time.

* test(artifacts): cancel ESP decoding after its first decoded chunk

The cancellation test requested cancel or close on setImmediate, which
can land while the file is still being opened and checked, so it never
showed that decoding had started. It also passed against a reader that
ignored both requests while decoding. Acknowledge the decoder's first
chunk, then cancel or close, join the operation, and assert that no
later chunk reaches the decoder and that the reader ends closed.

* docs(artifacts): record which ESP metadata comparison ignores

Segments are compared by their declaration. The image's and the
signature blocks' format_metadata are not: every field comes from their
own bytes, which content comparison already covers, and a block's
image_digest_matches follows the image's content.

* docs(artifacts): state that ESP mmu_page_size is a base-2 logarithm

The app descriptor's mmu_page_size keeps ESP-IDF's name and value, the
MMU page size in log base 2 as esp_app_desc_t declares it, so 16 means
64 KiB. Say so in docs/esp-image.md and the schema comment; a reader
could otherwise take 16 as 16 KiB.

* fix(esp-image): retain member consumption and share lifecycle regressions

* test(artifacts): scope MCP catalogs and budget full-schema validation

* test(artifacts): verify compact output profiles and document bounded catalogs

* test(artifacts): close readers when cleanup-test admission fails

* test(artifacts): compare ESP image limitations with their owners

The decoder and reader tests froze complete limitation sentences, so a
harmless rewording failed them. The wording now has two owners:
ESP_IMAGE_LIMITATIONS in espImageFacts.ts, which the decoder, the inventory
and the reader use, and ESP_DESCRIPTOR_LIMITATIONS beside the descriptor
decoder. Tests compare delivered limitations with the owner, called with the
facts each case establishes (segment index, declared and available bytes,
offsets, chip, page range), next to the structured assertions they already
make. Delivered text is unchanged.

* test(esp-image): assert structured facts and owned guidance

* fix(esp-image): keep spi_flash_mode and descriptor fields before a truncated tail

ESP-IDF v6.1's esp_app_desc_t declares spi_flash_mode at byte 181, after
mmu_page_size, as the committed reference layout shows; the descriptor now
keeps it as stored. The decoder also required all 256 descriptor bytes,
though it reads none past byte 181, so a file ending in the reserved tail
lost the version, project, digest and revision facts it does hold. The app
descriptor now needs only its fields; the segment's truncation is reported
as before.

* test(esp-image): pin the P-192 public key digest to espsecure's layout

espsecure packs ECDSA signature blocks as "<BBBx32sB64s64s1031x" and
zero-pads a 48-byte P-192 point to 64 bytes, so the signature starts at
byte 101 for every SHA-256 curve. signature_info_v2 hashes sig_block[36:101]
and _digest_sbv2_public_key the curve ID with the padded point. No test built
a P-192 block; this one checks public_key_sha256 against that definition.

* fix(esp-image): keep each app descriptor field the file holds in full

A file can end anywhere inside the 256-byte esp_app_desc_t. The decoder
needed every field byte, so a cut at byte 176 dropped the version, project
and app_elf_sha256 it does hold. Once the 4-byte magic identifies an app
descriptor, each field is now kept when the file holds all of its bytes and
is null otherwise; observed_length records where the descriptor ends, so a
cut field is told apart from text that is not UTF-8. The fields after the
magic become nullable in the metadata schema.

* fix(esp-image): report a signature block whose image digest does not match

A CRC-valid Secure Boot v2 block can carry another image's digest. The
block recorded image_digest_matches false, but no limitation said so, unlike
a checksum or appended-SHA mismatch, so CLI and MCP summaries showed only
the generic unverified note. The mismatch is now a limitation; coverage
stays complete and signature_status stays unverified. The three other
signature-sector limitations move into ESP_IMAGE_LIMITATIONS with their
text unchanged, so all ESP image wording has one owner.

* refactor(esp-image): remove redundant descriptor byte guards
