It does not modify product code or inspect user state: fixture +data is synthetic and all scenario roots are temporary. Ordinary MCP scenarios +exercise `icm_mcp::McpService` directly; process-backed lanes retain a cleared +environment for isolation, proxy, and topology assertions. +The committed design is the contract; the runner invokes a real ICM +binary for process-backed lanes and records real wire responses, +synthetic-tree mutations, configured loopback HTTP integration traffic, and +process topology. A staged suite copy must include this package manifest, +contracts, fixtures, and goldens; normal workspace operation uses the crate +path directly. The frozen `productCratePathDependenciesAllowed: false` field +applies to fixture construction: SQL/JSON fixture generation remains free of +product crates. The workspace evaluator itself links only `icm-mcp` and +`icm-store` for its integrated service lane. + +The initial design was frozen on 2026-08-05 before replacement implementation. +Later revisions are post-implementation audit/spec corrections. v9 was frozen +before the initial final-candidate run. That run exposed stale evaluator-only +provider journal and revision-sensitive proxy-header assumptions. v10 fixes +those assumptions and closes provider-state, Git-ancestry, and cross-scenario +canary gaps before the corrected candidate run. Its first two-root self-test +then exposed three stale modern text-ULID normalization rules; v11 removes +them because modern IDs live in `structuredContent` and concise text does not +duplicate them. Its completed two-root diff then identified the remaining +dynamic structured IDs and timestamps; v12 declares only those exact pointers. +The 294 scenarios and all thresholds remain unchanged. +The pre-implementation upstream observation remains frozen in +`goldens/baseline-metrics.json`, including its source commit and candidate +binary hash. + +The required lane provides portable controlled-input isolation: + +- every scenario receives a new synthetic home, XDG tree, Windows profile + tree, database, configuration tree, working directory, and environment; +- the child environment is cleared and rebuilt from an explicit allowlist; +- embeddings are disabled for product behavior and the proxy topology lane + uses a deterministic loopback mock daemon/model; +- no provider account, credential, real configuration, Git configuration, + external service, fixed port, shell, `/tmp`, or host-specific absolute path + is used; +- the dedicated workspace is rejected beneath inherited provider state or any + Git worktree ancestor; +- fixture hashes are verified, and each high-entropy deterministic canary is + checked after every scenario for integrity and absence from captures and + newly created scenario trees; +- candidate commands and the mock daemon are owned by timeout-bounded RAII + guards that kill and reap children on success, error, and timeout; +- the normalized suite is run under two distinct roots (one with spaces and + one with Unicode) and must produce byte-identical results. + +Host PSS and real-model observations are supplemental only. They can never be +required for the portable acceptance result. + +## Build and run + +From the repository root, verify the in-workspace suite and build the +process-backed candidate separately: + +```bash +cargo build -p icm-mcp-eval --locked --offline +cargo run -p icm-mcp-eval --locked --offline -- verify-design \ + --suite-root crates/icm-mcp-eval +cargo build -p icm-cli --locked --offline --no-default-features \ + --features backend-sqlite,http-api +``` + +The full runner intentionally operates on a staged suite in a dedicated, +non-Git workspace. This keeps candidate paths and all generated evidence out +of the checkout and makes the same command usable in CI: + +```bash +set -euo pipefail +root="$(mktemp -d /tmp/icm-mcp-eval.XXXXXX)" +mkdir -p "$root"/{suite,candidate,runs/self-test,evidence} +cp crates/icm-mcp-eval/Cargo.toml "$root/suite/" +cp -a crates/icm-mcp-eval/contracts \ + crates/icm-mcp-eval/fixtures \ + crates/icm-mcp-eval/goldens "$root/suite/" +install -m 0755 target/debug/icm "$root/candidate/icm" +target/debug/icm-mcp-eval self-test --expect candidate \ + --workspace-root "$root" \ + --suite-root "$root/suite" \ + --candidate "$root/candidate/icm" \ + --work-root "$root/runs/self-test" \ + --evidence-root "$root/evidence" \ + --run-label candidate +``` + +To inspect a non-acceptance observation instead, use `record-baseline` with +an explicit run label. It never updates committed goldens. `--expect +baseline` permits `UNSUPPORTED_BASELINE`; `--expect candidate` requires every +scenario to pass. The current frozen inventory includes provider scenarios, +which require the candidate's trusted-provider CLI capability. + +All paths may be relative or absolute. The runner resolves them before +creation. Candidate, suite, work, and evidence must be disjoint strict +children of a dedicated, non-Git workspace. The workspace may be below +`HOME`, but it may not equal `HOME`/`USERPROFILE` or lie within inherited or +standard-default XDG, app-data, or macOS Library state directories. +Candidate environments, arguments, and working directories are checked not to +receive those real-state locations. Normalized output stores placeholders. + +The package is named `icm-mcp-eval`, but frozen protocol identities may still +contain `icm-cleanroom-eval` or `icm-cleanroom-mock`. Those strings are +contract data covered by checksums/goldens; renaming them requires an explicit +contract revision, not a package rename. + +Provider scenarios are frozen in the 294-scenario inventory. They require +the production candidate's trusted-provider CLI (`icm provider ...`); a +candidate without that capability is reported as unsupported in baseline +mode and fails candidate acceptance rather than being silently omitted. + +The loopback gate proves that configured proxy endpoints and the mock +integration's recorded peer/local sockets are loopback. It does not claim OS +firewall enforcement or observation of arbitrary sockets. Likewise, the +canary gate proves unchanged bytes and non-disclosure in stdout, stderr, raw +exchanges, and the scenario tree; it does not claim detection of an arbitrary +silent read. + +`record-baseline` is intentionally separate from `run`: it writes an observed +artifact but never silently updates the committed SHA-256 golden contract. +Updating a golden requires an explicit reviewed file change. `run` enforces +all candidate gates and exits unsuccessfully if a capability is missing or a +scenario fails. diff --git a/crates/icm-mcp-eval/contracts/checksums.sha256
