test(firmware): retain unverified workers before further launches

Scan eligible candidate relations directly for query ambiguity instead of allocating and sorting another traversal index. Preserve direction, relation filters and cycle handling.

Semantic graph and builder suites plus public application workflow CLI tests passed. Full query outputs matched on a generated 20000-node graph; the single repeated-query timing run is indicative only.

+# ADB device inspection and acquisition
+
+REA inspects connected Android devices, reads device state, and transfers
+files and packages through the caller's `adb` binary. Emulators, USB
+devices, and network devices participate alike: REA neither starts nor
+manages them and never installs platform tools. Every operation composes a
+fixed adb argument vector — caller values occupy positional arguments only
+and are quoted when adb forwards them to the device shell.
+
+The adb client may start its local server on first device query; that is adb
+client behavior, recorded in the tool result when observed.
+`inspect_adb_client` probes only the binary and never contacts the server.
+
+## Supply tools
+
+Use any Android platform-tools `adb` (verified with 34.0.5). Select it
+through the environment:
+
+```sh
+# Optional: absolute path to the adb binary; without it, adb resolves from PATH.
+export REA_ADB_PATH=/absolute/path/to/adb
+```
+
+REA never installs the Android SDK, an emulator, or a system image.
+Readiness is `rea inspect-adb-client`: it runs `adb version` and reports the
+resolved binary, its version, and where it was selected from. A missing
+binary reports `capability_unavailable` with the `REA_ADB_PATH` remediation
+rather than attempting an installation.

+
+Equivalent MCP methods use the snake_case names (`list_adb_devices`,
+`pull_adb_package`, `resolve_adb_packages`, …). Device operations take
+`serial` exactly as `adb devices` reports it. The pulled APK set feeds the
+existing analysis families directly, for example
+`rea inspect-android-package /tmp/acq/<package>/base.apk`.

+## Interpret the result
+
+- **Inferences carry their basis.** Device `kind` reports
+  `kind_basis` (serial prefix or USB transport); APK `role` reports
+  `role_basis: file_name`; `emulator_observed` is the build's own
+  `ro.kernel.qemu` value, `null` when absent.
+- **Device paths are not host paths.** `base_apk_device_path` values live on
+  the device filesystem. Only pulls and captures produce host-local paths,
+  each paired with byte size and SHA-256 digest.
+- **Splits are part of the answer.** `pm path` enumerates the base APK and
+  every installed split; pulls cover the whole set. System packages whose
+  APKs keep other names report the `unknown` role rather than guessing.
+- **Partial results keep facts.** Failed individual pulls return successful
+  artifacts with `coverage: "partial"` and per-file `failures`. Listings
+  that contain unrecognized lines report them as `unparsed_lines` and mark
+  partial coverage instead of dropping rows.
+- **Mutations are explicit.** `push_adb_file`, `install_adb_package`, and
+  `uninstall_adb_package` declare `mutatesTarget` and never run implicitly:
+  pushes refuse existing device files unless `overwrite` is set and verify
+  the transfer with the device's own `sha256sum`; installs preserve the
+  device's `Failure [...]` reason verbatim.
+- **Producer identity stays attached.** Every result embeds the producing
+  adb client (`binary_path`, `path_source`, `version`, `installed_path`).
+
+## Resource and lifecycle limits
+
+- Caller values reach adb only as positional arguments in fixed vectors;
+  no tool accepts an arbitrary shell command line, and UI interaction
+  (`input`, `am`, `monkey`) is deliberately not exposed.
+- Per-invocation budgets: client/devices 10-20 s, shell reads 20-60 s with
+  64 KiB-8 MiB capture caps (logcat 4 MiB, screen 32 MiB), transfers and
+  bugreports 600 s. Exceeded budgets report `resource_constraint`; stopped
+  commands report `provider_timeout`.
+- Pull and capture outputs are additive: the destination must not already
+  exist. Re-running a completed pull refuses the existing directory instead
+  of overwriting evidence.
+- Cancellation during a package pull preserves caller-selected output. The
+  error includes partial observations identifying completed artifacts and the
+  interrupted local path; remaining APKs were not attempted.
+- Failed package acquisition rollback retains its directory identity and retries
+  cleanup before later work and during shutdown. Cleanup refuses a replacement
+  directory. Terminal shutdown stops admission and drains active operations.
+- The provider holds no long-lived processes; every invocation is one
+  bounded adb run. The adb server belongs to the caller.

+# Apktool resource decoding
+
+REA decodes Android resource tables and the binary manifest through the
+caller's Apktool launcher. This completes the static triad for Android
+targets: Java/Kotlin sources through the JADX family, engine-grade
+decompilation through JEB, and resources through this family. REA never
+installs Apktool or a Java runtime.
+
+## Supply tools
+
+Use Apktool 2.7.0 or newer (verified with 2.7.0) and a Java runtime the
+launcher can find. Select the launcher through the environment:
+
+```sh
+# Optional: absolute path to the apktool launcher (upstream wrapper or a
+# java -jar script); without it, apktool resolves from PATH.
+export REA_APKTOOL_COMMAND=/absolute/path/apktool
+```
+
+Readiness is `rea inspect-apktool-client`: it runs `apktool --version` and
+reports the resolved launcher, its selection source, and its version. A
+missing launcher reports `capability_unavailable` with the
+`REA_APKTOOL_COMMAND` remediation rather than attempting an installation.
+
+## Answer an analyst question
+
+```sh
+rea inspect-apktool-client
+rea decode-android-resources /targets/Example.apk
+rea decode-android-resources /targets/Example.apk --locale de
+rea decode-android-resources /targets/Example.apk --no-strings
+```
+
+Equivalent MCP methods are `inspect_apktool_client` and
+`decode_android_resources`. The decode request takes `path`, an optional
+`locale` (project `res/values-<locale>/strings.xml` instead of the default
+table), and `include_strings` (default true). Regional locales such as `pt-BR`
+select Android's `values-pt-rBR`; Android qualifiers such as `pt-rBR` and
+`b+zh+Hans+CN` may also be supplied directly.
+
+## Interpret the result
+
+- **An owned APK snapshot is digested and decoded.** `target.sha256` and
+  `target.bytes` bind the observation to the exact APK that was decoded.
+- **Metadata comes from apktool.yml as apktool printed it.** Version codes
+  keep their own spelling (`'7'` versus `7`); `package_name` is read from
+  the decoded manifest, not inferred.
+- **The manifest is the decoded text**, bounded at 512 KiB and reported as
+  truncated when larger.
+- **Strings are projected verbatim.** Escaped entities stay escaped, and
+  entries containing nested markup (`<b>`, `<xliff:g>`) are counted as
+  unparsed rather than flattened — the limitation names the count. The
+  default table is bounded to 2000 entries with partial coverage when more
+  exist; `locales` lists every `values-<locale>` that has a strings table.
+- **Smali is skipped by design** (`apktool d --no-src`): Java-source
+  recovery belongs to the JADX family. Resource smali edits and rebuild are
+  a follow-up lane with mutation authority.
+- **Workspaces are owned and short-lived.** Decoding happens in a
+  provider-owned temporary directory that is removed before the result is
+  returned. The APK snapshot and framework cache both live inside this directory.
+  If removal fails, the result names the residual path and the provider retains
+  ownership for a cleanup retry on close, including failed decodes.
+
+## Resource and lifecycle limits
+
+- The decode runs with a 600 s deadline and a 4 MiB output capture budget;
+  a stopped decode reports `provider_timeout` and exceeded budgets report
+  `resource_constraint`.
+- Manifest reads are bounded to 512 KiB before decoding UTF-8. Strings XML
+  reads are bounded to 8 MiB; larger documents are skipped with partial
+  coverage and an explicit limit, rather than reported as missing.
+- `decoded_file_count` is capped at 100,000 files; the cap is reported in
+  the limitations when hit.
+- Apktool's own decode failures (`AndrolibException`, directory traversal
+  refusals) surface as `unsupported_target` with apktool's reason preserved
+  verbatim.
+
+## Real verification
+
+`npm run verify:apktool -- --apk PATH` exercises both operations against a
+real launcher. Record: apktool 2.7.0-dirty (Debian packaging) on Linux with
+OpenJDK 25 against a signed aapt2-built probe APK carrying two resource
+locales — launcher version, on-disk digest agreement, apktool.yml metadata
+(1.2.3, SDK 24–34), manifest package agreement, default and `de` string
+tables projected. Parser goldens in the test suite come from the same
+decode. See `docs/testing.md` for the lane summary.

+# MIPS ELF analysis through Ghidra
+
+This lane extends native ELF analysis; it does not execute MIPS code or rehost
+firmware. It advances the generic-MIPS portion of
+[#718](https://github.com/morluto/rea/issues/718), not the whole firmware roadmap.
+PSP/Allegrex remains a separate specialization tracked in
+[#1330](https://github.com/morluto/rea/issues/1330).
+
+## Admission boundary
+
+ELF `EM_MIPS` is retained as the provider-neutral `mips` family. The target also
+retains class, byte order, `e_type`, raw `e_flags`, and inspected ABI declarations.
+Recognition does not mean every provider or MIPS variant is supported. Existing
+PE, managed and Mach-O architecture sets are unchanged.
+
+The first Ghidra lane admits ELF32 `ET_EXEC`, little or big endian, with explicit
+o32 and `EF_MIPS_ARCH_32R2` flags and no machine-specific or ASE encoding flags.
+These are header declarations, not proof that every instruction conforms to
+that ISA. ELF64, n32/n64, unspecified ABI, MIPS16/microMIPS, machine-specific
+variants, shared/relocatable objects and PSP PRX are not covered by this lane.
+Their family may be identified, but provider selection returns the specific
+unsupported constraint rather than guessing a compatible profile.
+
+Explicit `EF_MIPS_FP64` and `EF_MIPS_NAN2008` declarations are refused. Their
+absence is insufficient: Clang can emit identical `e_flags` for FP32, FP64 and
+soft-float targets. Target resolution also reads the 24-byte ABI flags record
+identified by `PT_MIPS_ABIFLAGS` and/or `SHT_MIPS_ABIFLAGS`, without relying on
+section names or the record being inside the initial 4 KiB header probe.
+Program and section declarations must agree; duplicate, conflicting, truncated
+or out-of-file records are rejected. Stripped section tables and section-only
+records are supported. Extended table numbering is explicitly unsupported.
+The field layout follows
+[`Elf_MIPS_ABIFlags_v0`](https://github.com/bminor/glibc/blob/master/elf/elf.h).
+
+Provider admission requires record version 0, MIPS32r2, 32-bit GPR/CPR1, no CPR2,
+and a double-precision or FPXX ABI declaration with no ISA extension, ASE or
+unknown general flags. Missing records remain unknown rather than defaulting
+to a compatible ABI, and this initial lane refuses them. Unknown record values
+are retained for diagnosis but do not gain provider support. These checks bind
+the declared interpretation; the integer-only fixture does not establish full
+floating-point behavioral conformance.
+
+MIPS header and ABI record facts are committed in the analysis profile so
+interpretation changes invalidate profile-bound snapshots. The support-lane
+identity is versioned independently of file identity. Evidence, lifecycle
+outputs and saved snapshots preserve the `mips` family. Hopper and IDA adapters
+do not implicitly gain MIPS support. Windows Ghidra P0 remains PE x86/x86-64 only.
+
+## Use
+
+With a caller-installed Ghidra and compatible JDK on a supported Linux/macOS host:
+
+```bash
+rea analyze /absolute/path/to/mips.elf --provider ghidra --json
+rea function /absolute/path/to/mips.elf function_name --provider ghidra --json
+```
+
+MCP uses the existing tools, including `open_binary` with an absolute path and
+`provider_id: "ghidra"`. No MIPS-specific tool catalog or emulator is introduced.
+Inspect instructions, caller relationships and data alongside pseudocode. In
+particular, delay-slot semantics are supplied by Ghidra, not reconstructed by
+REA's ELF parser.
+
+## Verification
+
+The source-owned freestanding fixture is `tests/conformance/c/mips.c`. The
+optional cross-target lane requires a caller-supplied Clang with MIPS targets,
+LLD, GNU `readelf`, Ghidra and its compatible JDK; ordinary host-native checks
+do not acquire these tools. `REA_MIPS_CLANG` selects Clang and
+`REA_MIPS_READELF` selects GNU readelf (for example `greadelf` on macOS).
+These are test-time prerequisites, not REA runtime providers.
+
+```bash
+GHIDRA_INSTALL_DIR=/absolute/path/to/ghidra npm run verify:ghidra:mips
+```
+
+The lane compiles both byte orders and never executes the targets. GNU readelf
+independently supplies header/ABI facts and symbol addresses, compared with the
+production REA target resolver before provider startup. Its version, bounded
+command output and selected tool path are retained in the verification report.
+The parser deliberately recognizes only this fixture's GNU output, rejecting
+missing, ambiguous or unexpected fields rather than substituting defaults.
+
+Existing public MCP operations check Ghidra's **observed** language/compiler
+specification and loaded-file hashes. The source-owned `mips-probe.S` supplies
+fixed ADDIU and conditional-branch encodings: verification checks bytes, length,
+immediate and direct destination, independent of decompiler variable names.
+Global and string bytes are checked at independently reported symbol addresses.
+ELF load-image results retain observations even though REA's independent
+load-image comparison currently covers DOS, not ELF; this lane checks those
+observations and does not relabel the upstream result as verified.
+
+CLI/MCP discovery and decompilation, direct calls, target/profile/Evidence
+identity, snapshot round-trip and final process cleanup remain covered.
+Pseudocode presence is a liveness check, not proof of semantic equivalence.
+Instruction decoding and reader agreement likewise do not establish runtime,
+delay-slot execution or complete floating-point semantics. Assertion regressions
+reject incorrect byte order, constants, destinations and loaded identities.
+Parser/profile tests are narrower checks, not substitutes for this real-provider
+run. Report the actual lanes run and leave unexecuted verification pending.

+- In the JEB GUI client, start the MCP server from the _File_ menu (or via the VIBRE assistant).
+- Headless, use JEB's documented programmatic route (`JebMcpServerInstance` from the JEB API) with the JEB client on your classpath; JEB 5.48's `-c` headless mode does not accept `--mcp` directly.

+
+All four are read-only with respect to the target file; only `open_jeb_project` changes engine-side project state, and Evidence records the endpoint, the caller-selected parameters, and the engine-reported digests. Mutation workflows the engine also offers (renames, comments, `save_project`, `close_project`) are intentionally not exposed yet.
+
+**Engine coverage note (verified):** JEB 5.48.0 headless MCP instances do not advertise `open_project` — the target must be selected when the engine client starts (`--infile` on the programmatic launcher, or the GUI's file opening). REA preserves that refusal with the engine's reason instead of failing silently; `open_jeb_project` completes only against engine builds that advertise the tool, such as GUI clients.
+
+## Semantics
+
+- Paths in `open_jeb_project` are resolved by the JEB process, not by REA; REA does not require the artifact to exist locally.
+- The engine caps `list_units` pages at 100; a full page is reported as `coverage: "partial"` because more units may exist. An empty remainder is `complete` only when fewer units than requested were returned.
+- When `decompile_jeb_item` omits `unit_path`, the engine implicitly selects the project's first code unit; REA reports `unit_path: null` and a limitation instead of guessing the effective unit.
+- Engine refusals (`success: false` envelopes) are preserved as unsupported-target errors carrying the engine's own message, for example a nonexistent item address.
+- An unreachable endpoint is a provider-availability failure with recovery guidance; REA does not retry or spawn the engine.
+
+Real-engine verification lives in the JEB lane described in [testing.md](testing.md); mock transport tests do not establish real-engine compatibility.

+`verify:grok-client` requires installed Grok Build (verified with the official

+POSIX lane isolates `GROK_HOME`, an independent Git workspace and additional
+skill roots, disables foreign configuration discovery, guards setup writes,

+loads the full skill through native `read_file`, queries all REA names and input

+If discovery reports `partial`, the native agent diagnoses REA registration and
+retries discovery. No startup-timeout override or fixed readiness delay is used.
+A larger Unicode-path fixture exercises native result offloading: the full
+retained Evidence is validated against its named schema, then native terminal
+queries recover the selected export facts, subject and full artifact digest in
+the next model request. This verifies useful artifact recovery without claiming

+The verifier does not create accounts or install clients. It guards setup

+and verifies native default shared-skill discovery and complete activation.
+Default deferred-schema delivery stays enabled: the native prompt advertises
+every REA tool, exact-name `search_tools` returns every input schema, and a native
+shell query recovers the saved catalog's count and digest when the client spills
