feat(pe): inspect import and delay-load tables (#6509)

* feat(pe): inspect import and delay-load tables

Add inspect_pe_imports / inspect-pe-imports to read PE32/PE32+ import
and delay-load directories without executing the image. The report keeps
DLL names, named and ordinal functions, ILT/IAT RVAs, and a pefile
import hash of the standard import table. A missing directory is
observed absence, not proof the image never imported APIs.

* fix(pe): default PE import fixture options

Allow peImportImage() without an argument so CLI and filesystem tests
can use the KERNEL32 sample without repeating an empty options object.

* test(pe): keep import path cases on the dedicated MCP contract

inspect_pe_imports already rejects relative MCP paths in its own
boundary test. Leave the shared absolute-path matrix to tools whose
handler issue projection matches that suite's expected shape.

* fix(native): index virtual-to-file mapping lookups

mappedFileOffset scans every mapping twice per span, so a parser that
translates one span per table entry costs sections x entries. Add
fileMappingLookup, which builds an O(n log n) interval index once and
answers each span in O(log n) with the same accept, reject and
translation results. A differential test checks it against
mappedFileOffset over randomized overlapping mappings and zero fills.

* fix(pe): report partial import evidence and exact pefile hashes

- Withhold imphash with an explicit reason whenever the standard import
  table is partial (unreadable names or thunks, missing tables), or when
  pefile 2024.8.26 would hash a different row sequence: invalid or
  truncated names, ordinal 0, descriptors without functions, tables its
  bounds or repeat/spread heuristics discard, and its 8192-thunk import
  symbol cap. Delay-load issues do not withhold it.
- Hash ordinal imports with pefile's complete ordlookup tables and its
  ord<decimal> fallback instead of declining unmapped ordinals.
- Report a nonterminal descriptor whose FirstThunk is zero, and a
  delay-load descriptor whose IAT or INT RVA is zero, as malformed_entry
  partial coverage instead of a complete empty inventory.
- Directory evidence lists the file spans actually consumed for the
  descriptor array and terminator; discontiguous mappings produce
  separate spans and separate Evidence ranges.
- Carry exhausted limits as PeImportLimitFailure.limit and derive
  recovery from it; the fixed 16 MiB retained-text ceiling reports a
  fixed allowance instead of max_file_bytes advice.
- Translate RVAs through the indexed mapping lookup and yield with a
  cancellation check every 1024 table entries.

* fix(pe): read only own ordinal tables for DLL names

DLL names such as constructor and __proto__ pass pefile's name rule but
resolved inherited object members, throwing before the ord<n> fallback.

+# PE import and delay-load tables
+
+`inspect_pe_imports` / `inspect-pe-imports` answers whether one selected local
+PE32/PE32+ image declares an `IMAGE_DIRECTORY_ENTRY_IMPORT` table, which DLLs
+and functions that table names, which delay-load descriptors are present, and
+the pefile-compatible import hash of the standard import table. It reads the
+file without executing it and does not require a Windows SDK or disassembler.
+
+```bash
+rea inspect-pe-imports /absolute/path/to/application.exe --json
+```
+
+The CLI resolves relative paths against the caller's working directory. MCP
+and the advertised input schema require an absolute filesystem path and
+preserve that exact selection:
+
+```json
+{
+  "name": "inspect_pe_imports",
+  "arguments": { "path": "/artifacts/application.exe" }
+}
+```
+
+## Observations
+
+The inline Evidence result contains the artifact path, SHA-256, and byte length.
+`import_directory` and `delay_import_directory` report the data directory RVA
+and size, or `null` when a directory is absent or zero. Their `locations` are
+the file spans actually read for the descriptor array and its terminator. When
+consecutive descriptors map to discontiguous file bytes (for example across a
+section boundary), each span is reported separately, and each becomes its own
+Evidence file-offset range.
+If the first descriptor cannot be examined, the directory declaration remains
+present with no consumed `locations`, and coverage is partial. Descriptors,
+thunks and NUL-terminated names stay within PE's 32-bit RVA space, including
+PE32+ images; earlier valid rows survive an overflowing descriptor walk.
+
+Each `imports[]` item reports the DLL name, descriptor RVAs, and named or
+ordinal functions with ILT/IAT RVAs. `delay_imports[]` reports RVA-based
+delay-load descriptors separately. `imphash` is pefile's `get_imphash()` over
+the standard import table only; delay-load rows do not participate. Ordinal
+imports use pefile's ordinal name tables and otherwise its `ord<decimal>`
+fallback.
+
+`imphash.md5` is `null` with a `reason` whenever the value would not be
+pefile's hash of this image: the standard import table is partial, or pefile
+would read a different row sequence (names it treats as invalid or truncates,
+ordinal 0, descriptors without functions, or tables its bounds and import
+symbol cap truncate). Delay-load issues do not withhold the hash.
+
+A missing import directory is observed absence of that table. It is not proof
+the image never imported APIs through another table or overlay.
+
+## Limits and failures
+
+The selected file is limited to 64 MiB by default (512 MiB maximum). At most
+256 import and delay-load descriptors are examined by default (4096 maximum),
+and at most 8192 functions across every table (262144 maximum). Malformed PE
+headers and exhausted DLL or function budgets fail without partial success.
+Decoded DLL and function names are limited to a fixed 16 MiB of retained text
+with no runtime override; `max_file_bytes`, `max_dlls` and `max_functions` do
+not raise it. Resource failures report the exhausted allowance as `limit`
+(`dlls`, `functions` or `retained_text`) with matching recovery.
+
+Unreadable DLL names, hint/name entries, or thunks are reported as partial
+coverage with `issues`. A descriptor whose required table RVA is zero (a
+standard `FirstThunk`, or a delay-load import address or name table) is
+reported as `malformed_entry` with no functions, never as a complete empty
+inventory. Delay-load descriptors that store virtual addresses rather than RVAs
+are recorded as `unsupported_form` and are not decoded.
+
+This workflow does not resolve bound imports, loaded IAT contents, or
+export-forward names in another DLL.

+# PE import inventory verification — 2026-10-24
+
+The analyst task is to list a local PE's standard and delay imports, keep source
+locations and partial facts, and obtain a pefile-compatible imphash only when
+the retained standard import sequence supports it. CLI and MCP use the same
+application service and static parser. Targets are read without execution.
+
+## Revisions and ownership
+
+- Original PR: `0b65cbcfe2bf78a808d41e12fa5aee9c0fc93da4`.
+- Main integration and mapping index: `336f83cbb08dcc02a2d4c932f9c82f2c7b83554e`.
+- Measured baseline: `073e2612e783dc38d3603cd7dcc9dc721c0d9412`, the preceding
+  integration with provider identity imports and artifact-failure classification
+  repaired so the runtime builds. The measured candidate uses the same provider.
+- Measured candidate: `105f4ea66ebc82e559fe1000aabe75ced3024a41`.
+
+`readPeImage` owns machine, image base, directories, alignments and declared raw
+section pointers. The import parser consumes those facts rather than reading the
+PE header again or substituting a missing base with zero. The shared mapping
+index preserves canonical ambiguous/unmapped failures and adjacent mappings.
+Its construction is O(n log n), with O(log n) nonempty range queries; both normal
+and failed lookups avoid a linear fallback. Indexed and canonical CString reads
+share one implementation and can reconstruct strings across physical sections.
+These structures belong to one parse, with no cross-request cache or invalidation.
+
+Derived ILT/IAT slots are checked against the 32-bit RVA space before a row is
+returned. A malformed table preserves preceding valid rows and reports partial
+coverage instead of failing the output schema. Named thunks are checked before
+conversion from bigint, retaining the exact source hex when reserved high bits
+are set. The format's named hint/name pointer uses 31 bits; see the
+[Microsoft PE format specification](https://learn.microsoft.com/en-us/windows/win32/debug/pe-format#import-lookup-table).
+
+Early cancellation preserves the caller's reason before input validation in
+PE imports and the two adjacent certificate/ELF-note services. Artifact failure
+classification consumes the shared owner's origin facts and regular-file error
+predicate; cleanup ownership and retry remain with `ArtifactResourceScope`.
+
+## Independent oracle and regressions
+
+The oracle is pefile **2024.8.26**, installed without dependencies into the
+temporary verification directory. Its `pefile.py` SHA-256 is
+`0d0eb68f0f169182613dc64b3ab50b20855508c1c1d2faafe8fccf23edb6a345`.
+The release's upstream commit is
+[`4b3b1e2e568a88d4f1897d694d684f23d9e270c4`](https://github.com/erocarrera/pefile/tree/4b3b1e2e568a88d4f1897d694d684f23d9e270c4).
+All **696** copied ordinal names match its three complete maps: 425 oleaut32,
+196 ws2_32 and 75 wsock32. Own-key lookup and `ord<decimal>` fallback are retained.
+The upstream MIT license is preserved in `licenses/` and the notices inventory.
+
+Independent byte fixtures establish these differences:
+
+- A cross-section function name is `Function128` in native mappings; pefile
+  reads `Functi`. A cross-section DLL name is `KERNEL32.dll` natively and
+  `KERNEL32.d` in pefile. Complete native facts remain useful, while hashing them
+  would produce a different valid-looking MD5.
+- pefile stops after 2,048 section headers. With imports in section 2,049, native
+  parsing retains both functions while pefile finds no import table.
+- pefile also stops at a null section header or a section with at least three
+  of its structural warnings. Native parsing can still see a later import table.
+
+The candidate checks byte-mapping compatibility from the parsed owner facts,
+including pointer/address normalization, section clipping and those stop rules.
+Unproven geometry withholds only the hash, with an explicit reason. Delay-only
+issues do not invalidate the standard table's hash. This is conservative
+compatibility checking, not universal qualification of every unusual PE layout.
+
+PE32/PE32+ IAT overflow and exact wide-thunk regressions fail on the old producer.
+The three section-stop cases fail on the precursor before its stop guard was
+added; the independent oracle sees no imports in each. All pass after correction.
+Each of the three early-cancellation services fails its null-reason control
+before the fix; afterward both null and caller-object identity are preserved.
+The existing retained-text failure already propagates through its tagged error
+and is not claimed as a newly fixed defect.
+
+Executed checks at the candidate stages:
+
+- **58** parser/mapping/image/cancellation checks pass. Randomized mapping
+  comparisons use the canonical mapper as an independent semantic oracle.
+- **172** selected domain/service/filesystem/CLI/MCP/artifact-lifecycle checks
+  pass before the final section-stop guard; sets overlap and are not added.
+- The final parser file passes after the stress fixture's header/section ranges
+  are made disjoint. **5** public CLI cases then pass, including both IAT widths,
+  a complete cross-section name, section-cap and null-section hash refusals.
+- Full static gates pass after provider integration and after the compatibility
+  guard. The initial missing artifact-failure API compile error was corrected.
+
+The public CLI checks parse actual responses with the named output contract.
+MCP tests exercise the real SDK and advertised schema. The artifact-consumer
+suite covers physical read errors, cancellation, cleanup failure and retry with
+the PE provider included. No deep native engine or Windows runtime was newly
+qualified by these static-format checks.
+
+## Shipped PE artifacts
+
+The two launchers come from the official
+[pip 24.0 wheel](https://files.pythonhosted.org/packages/8a/6a/19e9fe04fca059ccf770861c7d5721ab4c2aebc539889e97c7977528a53b/pip-24.0-py3-none-any.whl),
+SHA-256 `ba0d021a166865d2265246961bec0152ff124de910c5cc39f1156ce3fa7c69dc`.
+They were extracted as analysis artifacts, without installation or execution.

+
+For both launchers the ordered DLLs, names, ordinals, hints, IAT RVAs, machine,
+bitness and imphash agree with pefile. The benchmark verifies the complete named
+rows, not merely the function count or MD5.
+
+## Completed-task costs
+
+Three alternating pairs per fixture execute one fresh public CLI process:
+`rea inspect-pe-imports PATH --json`. All **24** tasks complete. Complete Evidence
+objects are equal across all six runs of each fixture, including provenance,
+coverage, limitations, locations and identity; nothing is stripped for equality.
+Artifact digests remain unchanged. The stress fixture contains 2,048 independent
+sections and 2,048 functions, SHA-256
+`0540676161eb7408805277a75e4d47e3d752732b6d5f294c59c8c670c7c1e905`.
+The empty fixture is 3,072 bytes, SHA-256
+`b32058d9121313554af54bc0aed762871d3d8eb5e2d9eeab6a365f0518c6f897`.

+
+Tokens use tokenx 1.3.0 estimates after timing, not actual model usage. The task
+uses known CLI commands without catalog/schema/help or continuation calls.
+Prompts, model framing, rendering and client JSON parsing are unmeasured.
+Node is 24.22.1 on Linux 6.1.0-54 x86-64, affinity CPUs 0–1, on a shared host.
+Every process is fresh; OS caches were not flushed and had prior oracle reads.
+There is no warm provider-cache measurement. Build/setup costs are separate.
+
+Elapsed ranges overlap, and the 50 ms profiler poll quantizes short-task timing;
+no speedup is claimed. The largest case's median increases about 0.10 s elapsed,
+0.07 s CPU and 2.9 MiB RSS for the additional correctness checks. RSS is the
+50 ms observed sum across descendants: shared pages may be counted twice and
+short/unobserved processes missed. CPU accounts for waited children. No resource
+stop occurred. The mapping index was already in the baseline, so these numbers
+do not isolate its speedup or qualify a 65,535-section worst case.
+
+## Main integration verification
+
+Integration `a5a1f919e896488d0651e621f334efec84e9132f` includes main
+`044c9705eadf62f7c47ddd42a0b2dc065b26b228`. The PE refinement is a type
+intersection with main's new container union; runtime PE interpretation is
+unchanged. The newly added Roman Urdu README receives the same PE imports link
+as the canonical table. The full static gate passes; documentation/license
+validation and test discovery pass after this link correction. The complete
+selected parser/mapping/image/service/filesystem/CLI/MCP/lifecycle selection
+passes **201** checks in 54.062 s (60.363 s waited-child CPU). Sets above overlap.
+Later main-integration performance was not remeasured; the cost table remains
+pinned to its recorded revisions. These tests use built-in static parsing, not
+a simulated claim of deep-engine behavior.
+
+## Additional RVA review and independent ordinal control
+
+The pre-merge review found a real missing boundary: PE32+ virtual mappings could
+carry descriptors, their terminator, or a DLL name beyond the 32-bit RVA end.
+Five new controls fail before correction (four standard/delay directory cases
+and one NUL beyond the RVA end). The producer now owns one RVA-span predicate
+used by primitive reads and partial row admission. CString reads include only
+bytes within that space. A name whose NUL is the final legal byte still passes.
+
+An unexamined first descriptor retains the declared directory with zero consumed
+locations and partial coverage. The schema represents that observation; the
+service rejects an empty consumed-span list claimed as complete. Four public
+CLI cases and the real MCP SDK/advertised AJV schema exercise both zero-span and
+preceding-row outcomes. The expanded selected workflow passes **213** checks
+in 71.408 s (71.595 s waited-child CPU). The full static gate passes. The earlier
+cost table remains pinned to its revisions; these later RVA checks were not
+included in that first measurement; the separate comparison below covers them.
+
+The ordinal-mask suggestion was tested rather than applied: installed pefile
+2024.8.26 itself uses `addr_of_data & 0x7FFFFFFF` in its ordinal corruption
+heuristic, including PE32+. Independent images with both ILT/IAT words rewritten
+produce these results:
+
+| Raw PE32+ thunk    | pefile result                                               | Native result                          |
+| ------------------ | ----------------------------------------------------------- | -------------------------------------- |
+| `8000000100000001` | ordinal 1 + ExitProcess; `72d9cd67504bb3b9f29c37a226bf4331` | identical, complete raw thunk retained |
+| `8000000000010001` | import table discarded; empty hash                          | hash withheld                          |
+| `8000000000000001` | ordinal 1 + ExitProcess; `72d9cd67504bb3b9f29c37a226bf4331` | identical                              |
+
+All three controls already pass before the RVA correction. Expanding the mask
+to 63 payload bits would diverge from this pinned pefile behavior. The reason
+text now specifies the low 31-bit payload; the raw thunk remains available, and
+matching pefile does not claim loader validity for reserved bits.
+
+## RVA-guard completed-task follow-up
+
+To measure the final guard separately from other integration changes, repeat
+three alternating pairs of the same four completed CLI tasks, now comparing
+`a7406eca8137c9fae58a12cb8354f042047f5045` against
+`feda57ae4ef420bc72e8e04393b75810da86cc3c` on their common main integration.
+All **24** tasks complete. All complete Evidence objects match across each
+fixture's six runs, and every ordered inventory field still matches the
+independent pefile oracle. Artifact digests stay unchanged; stderr is empty.
+The token estimator, invocation/discovery scope, process/cache conditions and
+profiler limitations are the same as the earlier measurement.
+
+| Complete CLI task          | Estimated stdout + invocation tokens, before → after | Elapsed median s |  CPU median s | Sampled family RSS median MiB |
+| -------------------------- | ---------------------------------------------------: | ---------------: | ------------: | ----------------------------: |
+| No imports                 |                                            676 → 676 |    2.220 → 2.019 | 2.383 → 2.382 |                 367.6 → 364.0 |
+| Shipped PE32               |                                        3,678 → 3,678 |    1.918 → 1.918 | 2.253 → 2.203 |                 366.8 → 367.9 |
+| Shipped PE32+              |                                        3,715 → 3,715 |    1.973 → 1.968 | 2.363 → 2.293 |                 368.9 → 369.3 |
+| 2,048 sections / functions |                                      70,342 → 70,342 |    2.825 → 2.221 | 2.423 → 2.428 |                 382.9 → 389.0 |
+
+No speedup is claimed. In the largest case, elapsed ranges are 2.019–3.085 s
+before and 2.019–2.776 s after. CPU medians differ by about 0.004 s; sampled
+RSS increases about 6.1 MiB (1.6%). Shared-host variance dominates the apparent
+elapsed improvement. This validates the measured completed tasks, not a maximum
+format-size or transport-buffer qualification. Later main changes remain
+outside these pinned measurements.
+
+## Coverage consistency
+
+Three new service controls reject contradictory standard-import, delay-import,
+and complete descriptor counts; all three fail before the correction. The
+service now compares counts with the retained rows before issuing Evidence.
+Partial results may still report more examined descriptors than retained DLLs,
+as verified with an unsupported delay descriptor. Complete results must agree
+and carry no issues. Existing function-count traversals are reused; the change
+adds no further row scan. These validation checks postdate the pinned cost
+measurements above.
+
+The expanded selection passes **217** checks in 73.179 s (70.360 s
+waited-child CPU), with a sampled process-family peak of 2,039.3 MiB. Full
+`npm run check` passes. These counts overlap earlier selections. A subsequent
+main integration at `7f70797b98c226009163358f91a9cfcedf03b390` includes the
+upstream plist-fixture correction for the three unrelated native-provider
+failures seen in CI run 40055148308.
+
+## Descriptor mapping stops
+
+A later review identified the same partial-result boundary when a descriptor's
+uint32 RVA is legal but lacks a file mapping. Four controls (standard/delay,
+first descriptor/after one row) all threw before correction. Both walks now
+use one descriptor admission function: range failures and mapping failures
+append explicit issues, then preserve the directory declaration, consumed
+spans and preceding rows. Only mapping failures are caught; unrelated failures
+continue to propagate. Standard-table failures withhold imphash; delay-table
+failures preserve an independently complete standard hash.
+
+The public CLI covers all four mapping-stop cases alongside the RVA cases.
+The actual MCP SDK and advertised output schema cover an unmapped first
+descriptor. These later validation changes are outside the pinned performance
+comparisons above; no additional speed or maximum-size claim is made.
+
+Final integration at main `7f70797b` passes **277** selected checks: the
+expanded PE/shared lifecycle selection plus native-provider tests that cover
+the upstream plist-fixture correction. This takes 126.978 s, 127.567 s
+waited-child CPU and 2,061.9 MiB sampled process-family RSS. These are test
+suite costs, not analyst-task costs. Full `npm run check`, `npm run docs:check`
+and test discovery pass; discovery accounts for all 2,323 files exactly once.
