Scope MCP discovery, setup, doctor, status and recovery guidance by selected tool families using one contract inventory and shared catalog identity. Preserve default discovery, canonical validation and complete Evidence.
Fixes#3246. Builds on #3026. Real libcrypto workflow verifies all 5,367 exports and identical complete Evidence. Static/source/build/docs/Windows/package/Greptile checks pass; ten assertions reproduced identically on clean main and feature across Node 24/22, with cancelled coverage explicitly unverified. Merge uses the user-authorized bypass for baseline failures and unchecked human-readiness declarations, without attesting human review.

Add opt-in bounded output-schema advertisements while preserving the full default, canonical server validation and complete structured content. Verify real stdio discovery under a 1 MiB receive cap, all 5,367 libcrypto export coordinates, complete Evidence parity, whole-task serialization estimates and resource bounds.
Fixes#2512. Integrates #7054 by Akshad Jogi with original authorship retained.

This reverts commit 7336a566ac (#7119).
After #7120 and the other merges of 2026-10-25 grew inspect_analysis_view's
complete input schema (71,762 bytes plus 3,003 bytes of examples), the 64 KiB
fitting from #7119 could no longer keep instance level 3 and fell back to
level 2. That summarized the inline Evidence source and the view selector
collections, so main CI failed in toolInputReferences, toolSchemaValidity,
analysisViewMcp, absoluteLocalPathSchema, javascriptFactsViewMcp and
godotPckMcp. #7119's own CI ran against bc143125e, before that growth.
Reverting restores the complete full-profile advertisement while the size
limit is redesigned against these contracts (#4081 stays open).

* fix(mcp): fit every advertised input schema within the 64 KiB client limit
Claude Desktop drops a local connector tool whose compact-JSON input
schema exceeds 64 KiB. The full input profile advertised
compare_web_captures at 171,867 bytes and inspect_analysis_view at
71,632 bytes, because the self-contained projection inlines the
complete producer capture schemas once per side.
The full advertisement now fits the limit at its producing boundary.
A property whose schema repeats an earlier sibling's points at it, and
schemas below the deepest instance level that fits are summarized as
their types, size constraints and descriptions. Every rewrite widens the
advertisement through the existing relaxation rules for oneOf, not,
if/then/else, contains and unevaluated keywords, so canonical inputs
stay accepted and the canonical contract still validates every call.
Schemas within the limit are unchanged, and the compact profile is
still presented from the complete projection.
Numeric const and enum literals are also relaxed in the advertisement,
like boolean literals, since Gemini accepts only string enum members.
Fixes#4081

* fix(mcp): keep fitted input summaries widening and at the deepest fitting level
Array summaries took item types only from `items`, so a tuple such as
`{prefixItems: [{type: string}], items: {type: number}}` was advertised
as a number array that rejected `["a", 1]`. Item types now include tuple
positions from `prefixItems`, a draft-07 `items` array, and
`additionalItems`, and stay unconstrained when later elements are open.
A summary can also be longer than the schema it replaces (a nullable
array becomes an anyOf), so candidate size is not monotone in the
retained depth and stopping at the first overflow could skip a deeper
candidate that fits. A schema is now kept whole when its summary is not
smaller, and fitting searches from the deepest level down.
Property tests check that every summary accepts what its schema accepts
over every catalog input subschema and synthetic tuples, and that the
fitted schema is the deepest fitting candidate. The browser comparison
boundary test now expects a malformed `after` capture to be rejected
canonically, since `after` is advertised as the same schema as `before`;
the same malformation on `before` stays advertised-invalid.

Use compact MCP input advertisements by default while preserving explicit full, canonical validation, output contracts and complete Evidence. Require an explicit selected catalog for runtime identity and honor both profiles in CLI status.
Real ripgrep/Zellij SDK tasks, independent ELF oracle, actual client trials, profile parity workflows and CI are recorded in experiments/analysis-efficiency/mcp-input-catalog.md. SDK token estimates improve; actual Codex token savings and general latency/memory gains are not established.

BREAKING CHANGE: MCP input advertisements default to compact. Set REA_MCP_INPUT_SCHEMA_PROFILE=full for complete advertised guidance and nested constraints.
Every `doctor`, `mcp doctor` and MCP server that reports or compares its
catalog identity rebuilt all advertised JSON Schemas and canonicalized
them to compute the default digests, about 200 ms of CPU per process.
The default (full input and output schema) catalog is a deterministic
function of the compiled contracts and pinned schema converter, so
compilation now records it once into dist and the runtime reuses it.
Compact and output-schema-off identities, and source runs, still compute
their digests on first use.

Include the selected output advertisement profile while retaining canonical output validation in the identity. Reuse the SDK output projection and select doctor expectations from both profiles. Correct the compact input error documentation.
Capture the current entrypoint once without inventing a path. Preserve unknown registration ownership through setup and doctor, refuse unsafe registration plans, and retain exact pinned-launcher readiness checks. Hash the same full or compact schema projection advertised by each MCP server and use that identity in doctor comparisons.
BREAKING CHANGE: server.command_path may be null when the invocation path is unavailable. Registration and setup statuses, and doctor classifications, may report unknown.

Use one named input-schema projection for clients and catalog identity, preserve dialect declarations, and bound compact schema depth. Keep canonical SDK output validation when output advertisements are disabled. Release request-owned state on cancellation and carry upstream limitations through composed workflows. Preserve doctor full-output envelopes and validate navigation facts at their owner.

Validation: focused schema, SDK output-validation, context, and workflow tests passed; no schema dialect or canonical output validation was relaxed.
* feat(server): frame analysis-target content as untrusted data
Strings, decompiled code, page text, scripts, captures and logs returned
by REA originate from the analysed target, which can embed text aimed at
the agent. Nothing marked that content, so a prompt injection inside a
binary or page could steer the agent toward tools that run code.
- Server instructions now state that target-derived tool output is data,
never instructions, and that any request in it to run, install,
download or send something is a prompt-injection attempt to report.
- Tool contracts declare returnsTargetContent. It is on by default; only
seven tools whose results hold REA session state or caller-supplied
values (binary_session, close_binary, export_evidence_bundle,
record_unknown, update_unknown, inspect_adb_client,
inspect_apktool_client) are audited exceptions, so new tools start
marked.
- Successful results of marked tools carry
_meta.provenance = { untrusted_content: true, source: "analysis_target" }.
content and structuredContent are unchanged, and the response budget
accounts for the fixed marker bytes.
Tests cover the encoding and budget accounting, the audited exception
list against the contract catalog, and an in-memory MCP client that sees
the instructions and the marker on a marked tool but not on
binary_session.
* fix(server): mark failed target-content results as untrusted too
The untrusted provenance marker was attached only on the success branch
of ToolResultDelivery, but failures can carry target-derived text as
well: error messages, captured output, and partial observations such as
the terminal frames a failed capture_process_scenario retains in
partial_observation. A host gating later process or device actions on the
marker would have treated an adversarial error payload as trusted.
Every error path in src/server now carries the failing tool's provenance:
- toErrorToolResult and toRecordedPartialErrorToolResult take the tool's
target-content flag explicitly, so each caller is audited by the type
checker; toCallToolResult, toEvidenceToolResult (recording failure), the
response-budget error that replaces an oversized success, and the
Electron partial-evidence path pass contract.returnsTargetContent.
- Admission failures in runAdmittedToolOperation resolve the flag from the
tool name through the new toolReturnsTargetContent, the same predicate
the contract metadata uses; unknown names stay marked.
- The transport's oversized-error replacement keeps the original's marker
and counts it in its budget check, matching the projected error.
- Errors the MCP SDK builds itself (input validation, thrown handlers) are
marked in the transport for target-content tools only.
Error encoding accounts for the marker bytes exactly as success encoding
does. docs/mcp-contracts.md now states that error results carry the
marker. Tests cover marked and unmarked error results, the
capture_process_scenario partial-observation errors in-process and over
the SDK transport, the recorded partial-evidence path, the budget
replacement, the oversized-error replacement, and SDK validation errors
for a marked and a content-free tool.
* fix(contracts): mark session status, close and client probes as target content
The content-free exception set was audited against successful results
only. Now that failures carry the marker too, every exception was
re-audited against its error paths with one question: can the result
include text produced by an external process, provider or device, or
stored content REA did not author?
Removed from TARGET_CONTENT_FREE_TOOLS:
- close_binary: a failed provider cleanup (GhidraClient cleanup error via
createGhidraDiagnostics) projects the launcher's captured stdout and
stderr, which can contain target-derived log text.
- binary_session: capability status reports runtime unavailability as the
provider error message (ProviderAdapterError and similar), and the
provider candidate and Android availability diagnostics include probe
output such as the apktool stderr excerpt.
- inspect_adb_client: the success result carries the version and
installed path parsed from `adb version` stdout, and a failed probe
keeps a stderr_excerpt.
- inspect_apktool_client: the success result carries the first line of
the launcher's `--version` output, and a failed probe keeps a
stderr_excerpt.
- update_unknown: the new revision carries forward the stored question
and domain, which an imported evidence bundle can supply; list_unknowns
and get_evidence_bundle already return that data marked.
The set now holds only export_evidence_bundle (path, byte and record
counts; failures are filesystem, cancellation, or a fixed integrity
message) and record_unknown (the caller's input plus REA-computed ids
and digests; registry errors project only a reason code).
The conformance test pins the reduced set and asserts each removed tool
is marked. Tests that used binary_session as the unmarked example now use
record_unknown. docs/mcp-contracts.md lists the remaining exceptions and
why the removed tools stay marked.
* fix(contracts): include target-content policy in the catalog identity
createToolCatalog() and CATALOG_IDENTITY.tools projected every
client-visible contract field except returnsTargetContent. Because the
untrusted-content framing left schemas, effects, prompts, CLI names and
the package version unchanged, a same-version MCP process started before
the update digested equal to the new server and binary_session reported
it aligned although it never emits _meta.provenance.
Project the flag as returns_target_content in both the digested tool
catalog and CATALOG_IDENTITY.tools, and export createCatalogDigests so a
boundary test proves that toggling the flag on one tool changes the
tools and combined digests.
Group repeated session tool availability and provider capability facts, preserve complete named contracts and ordered limitations, and remove duplicate catalog descriptors. Update consumers and migration guidance.
Validated by all 31 CI jobs, focused source checks, and actual Claude Code/Linux Hopper/native Windows Ghidra small-target workflows on the current integration tree.

BREAKING CHANGE: binary_session no longer includes server_identity.catalog.tools; tool_availability and provider capabilities use grouped facts documented in docs/mcp-contracts.md.

* fix: order remaining outputs independently of host locale
String.prototype.localeCompare without a pinned collation follows the
host's ICU default locale, so the same input could be ordered differently
on different machines. 614fb768 moved canonical domain projections to
compareUnicodeCodePoints; provider, application, catalog, and setup
orderings still used locale collation.
Order every remaining source site by Unicode code point, including Mach-O
symbols, firmware extraction paths, ASAR entries (previously pinned to
"en" collation), evidence ID sets, browser and Electron target, script,
and resource inventories, reconstruction obligations, capability and
provider listings, and setup environment details.
The current tool and prompt catalog names order identically under both
comparators, so the catalog identity digest is unchanged.
* fix(artifacts): order ASAR entries by their portable path
@electron/asar lists host-spelled paths, so code-point order over the raw
spelling still differed by host: "a\b" sorts after "a0" on Windows while
"a/b" sorts before it on POSIX. Pair each listing with its portable
archive path once, order by that path, and keep the host spelling for
@electron/asar calls and adapter keys.
Add immutable session bundle snapshots, bounded resource discovery, paginated unknowns, mutable current analysis snapshots, and provider-neutral navigation/address context tools.
BREAKING CHANGE: export_evidence_bundle now requires a filesystem path and no longer returns an inline bundle.
BREAKING CHANGE: comparison tools now require session-owned Evidence IDs or approved bundle paths, and structured Evidence results use compact references.
Derive package, tool-family, provider, setup-client, schema-version, and CLI facts from the runtime contract sources into a deterministic checked-in catalog.
Add non-mutating generated-file checks, exact TypeDoc regenerate-and-compare validation, caller-visible documentation fact checks, and CI enforcement through docs:check.
Cover command-router parity, source-derived catalog values, deliberate documentation drift, and stale generated artifacts while preserving runtime behavior.
