 ## Status
 
-Version `0.3.0` adds fail-closed post-publication provenance and model-card rendering, fixes underspecified deterministic grader contracts, and keeps the routine gate safe through 131,072 prompt tokens on 64 GiB Apple Silicon hosts. Maximum-window qualification is an explicit, separately configured run. Public leaderboard claims additionally require the release suite, rotating holdout seeds, raw result publication, and the policy in [docs/leaderboard-policy.md](docs/leaderboard-policy.md).
+Version `0.5.0` adds a frozen 30-case expanded agentic matrix, four disposable-repository repairs with hidden tests, declared JSON key/type contracts, grounded receipt projection, and repeat-trial summaries. The lightweight six-case quant gate remains unchanged. The optional **Shiftedx Agent Harness** receives no hidden expected values, uses the public profile identifier `shiftedx-harness-v1`, and never replaces the default baseline. Version 0.3's fail-closed post-publication provenance, model-card rendering, and safe routine gate through 131,072 prompt tokens remain intact. Maximum-window qualification is an explicit, separately configured run. Public leaderboard claims additionally require the release suite, rotating holdout seeds, a sanitized per-case ledger, and the policy in [docs/leaderboard-policy.md](docs/leaderboard-policy.md).
 
 This benchmark does not claim to replace RULER, HELM Long Context, NoLiMa, LiveCodeBench, BFCL, SWE-bench, or broad academic evaluations. Its distinctive purpose is paired local-deployment qualification across quality, context, multimodality, and runtime acceleration.

+### Optional Shiftedx Agent Harness
+
+The **Shiftedx Agent Harness** is an optional, model-agnostic inference-time execution layer inside Shiftedx Bench. Its first public profile, `shiftedx-harness-v1`, tests whether explicit receipt-grounded state improves tool-use reliability without changing model weights or the serving runtime. It classifies structured tool receipts, blocks identical calls within an unchanged state epoch, preserves unresolved verification failures across investigation, requires verification after successful mutations, and allows at most two correction turns for malformed or unsupported final JSON. When a model repeats an already successful call and the evidence is sufficient, the harness disables tools for the next request and asks it to finalize. It never invents a tool result or reads hidden expected values.
+
+See [docs/shiftedx-agent-harness.md](docs/shiftedx-agent-harness.md) for the trust boundary, state machine, telemetry, and reporting contract.
+
+Run it as a paired experiment against the unchanged baseline:
+
+```bash
+.venv/bin/shiftedx-bench run-suite \
+  --suite agentic \
+  --config configs/suites-smoke-v1.json \
+  --base-url '<openai-compatible-base-url>/v1' \
+  --model '<served-model-id>' \
+  --label '<model>-shiftedx-harness-v1' \
+  --thinking on \
+  --reasoning-effort medium \
+  --agentic-control-profile shiftedx-harness-v1 \
+  --output results/agentic-shiftedx-harness-v1.jsonl
+```
+
+The profile is disabled by default. It never reads scenario `expected_final` values or required-call sets while steering; those remain grader-only data. Report baseline and controlled accuracy separately along with emitted calls, dispatched calls, blocked duplicates, correction turns, total wall time, and decode throughput. A controller result is not a claim that the underlying quant became more intelligent.
+
+For broader qualification, select the 30-case deterministic matrix or the four disposable-repository repairs:
+
+```bash
+# Stale evidence, status payloads, repairs, recovery, parallel reads, and safety refusals.
+.venv/bin/shiftedx-bench run-suite \

+  --agentic-control-profile shiftedx-harness-v1 \
+  --label '<model>-shiftedx-harness-repo' \
+  --output results/agentic-repo.jsonl
+```
+
+Use `--case-id <id>` for a targeted diagnostic, not for a promotion claim. Summarize complete repeated runs without copying raw responses:
+
+```bash
+.venv/bin/shiftedx-bench summarize-agentic \
+  results/baseline-*.jsonl results/shiftedx-harness-*.jsonl \
+  --output results/agentic-trials.json
+```
+
+Receipt projection is deliberately narrow: a successful structured receipt may be projected only when it contains every declared output key with the declared JSON type, and a green `N passed` verification may produce the declared `{status, tests}` object. It cannot infer missing values or bypass a failed verification.
+
+Before attaching results to a public model card, export a sanitized ledger and manifest. This command removes model responses, transcripts, raw errors, local paths, request/session identifiers, and host-environment details while retaining per-case outcomes, public-safe telemetry, immutable revisions, and the declared request contract:
+
+```bash
+.venv/bin/shiftedx-bench export-public-results \
+  results/agentic-expanded.jsonl \
+  --output public/agentic-expanded.public.jsonl \
+  --manifest results/agentic-expanded.manifest.json \
+  --manifest-output public/agentic-expanded.manifest.public.json
+```
+
+Keep the raw JSONL as private audit evidence. Run `validate-release` against the clean public tree, not the working results directory.

+Shiftedx Bench and evaluated model cards use immutable, two-revision provenance. Never benchmark or cite a moving `main` branch.
+
+## Publish the benchmark
+
+1. Freeze the version, configurations, schemas, CLI help, and changelog.
+2. Run the complete test suite and `shiftedx-bench validate-release --root .` against a clean source tree.
+3. Publish the clean tree to `Shiftedx/shiftedx-bench` in one release commit.
+4. Fetch the repository anonymously, record the full commit SHA, and confirm the version and public file list from that immutable revision.
+
+## Qualify a model
+
+1. Record the model's immutable weight-bearing Hugging Face commit.
+2. Serve byte-identical weights from that revision using the intended public runtime contract.
+3. Run the lightweight gate with both `--hf-revision` and `--benchmark-revision` set to full immutable commit SHAs.
+4. For Shiftedx Agent Harness claims, run complete paired `baseline` and `shiftedx-harness-v1` treatments under the same model, runtime, sampler, reasoning mode, tools, case order, and budgets. Use at least three complete trials for a promotion claim.
+5. Generate aggregate summaries only after every expected row and manifest exists.
+6. Export public ledgers and manifests with `export-public-results`; retain raw JSONL privately.
+7. Render the standard model-card block from the complete post-publication run. Report baseline model scores separately from harness-assisted deployment results.
+
+## Publish the model-card enrichment
+
+1. Stage the README plus sanitized aggregate/ledger artifacts in a clean directory.
+2. Run the public-release scanner on that directory.
+3. Commit only metadata and sanitized benchmark artifacts; do not modify weight files.
+4. Verify the rendered card anonymously at the new commit.
+5. Confirm that all weight LFS hashes still match the recorded weight-bearing revision.
+
+Do not publish access tokens, raw model responses, prompts, transcripts, local paths, request/session identifiers, private host names, or interrupted maximum-window outputs. A watchdog or out-of-memory event is a host operability limit, not an incorrect model answer.

+## Agentic execution profiles
+
+The default `baseline` profile sends the scenario system prompt, task, tool schemas, and tool results without an external execution layer. `shiftedx-harness-v1` is the first Shiftedx Agent Harness profile and is an opt-in paired treatment; it must never replace baseline results in a model-quality scorecard.
+
+The harness operates only on observable request and tool-result state. It records success or failure receipts, scopes duplicate suppression to a state epoch, advances that epoch after a successful mutation, requires a later successful verification receipt, and validates only the task's declared bare-JSON output shape. Hidden expected answers and grader-required tool sets are not harness inputs. At most two terminal correction turns are allowed.
+
+Declared output contracts include both key names and JSON primitive types. Grounded receipt projection may eliminate a final model turn only when a successful structured receipt itself contains the full declared schema, or when a successful verifier reports an exact `N passed` result for a declared `{status, tests}` response. Projection is recorded in telemetry and may not supply an unstated value.
+
+The `expanded` scenario set contains 30 cases across repair loops, stale evidence, structured status, wrong-path recovery, parallel reads, and underspecified destructive-action refusal. The `repo` set creates four fresh temporary source trees, permits writes only to the named source module, statically screens replacement code, and executes visible plus hidden assertions through the resource-limited Python sandbox. Hidden assertions are never included in prompts or controller state. Disposable-repository results are still small-fixture evidence, not SWE-bench claims.
+
+For a valid comparison, keep model artifact, server, sampler, reasoning mode, tools, cases, and case order fixed. Report both emitted and actually dispatched tool calls because duplicate suppression can reduce external side effects without reducing the model's attempted calls. Also report correction turns, total prompt/completion tokens, wall time, and per-turn decode telemetry. Treat higher accuracy bought through unbounded retries or materially larger token budgets as a different operating point, not a free quality improvement.

+# Shiftedx Agent Harness
+
+The Shiftedx Agent Harness is an optional execution layer for agentic evaluations in Shiftedx Bench. It is designed to answer a narrow operational question: does a model complete tool-driven work more reliably when observable tool receipts are converted into a small, explicit state machine?
+
+The first profile is `shiftedx-harness-v1`. It is disabled by default and is always evaluated beside the unchanged `baseline` profile.
+
+## What it does
+
+The harness:
+
+- classifies tool results from structured status before considering incidental words such as `error`;
+- records compact success/failure receipts without copying tool-result contents into harness state;
+- blocks identical calls within an unchanged state epoch;
+- opens a new epoch after a successful mutation;
+- requires successful verification after mutation;
+- preserves failed verification across later inspection;
+- stops unbounded inspection after a diagnosed verification failure when a mutation tool is available;
+- validates declared bare-JSON keys and primitive types;
+- permits at most two terminal correction turns; and
+- projects a final JSON object only from a complete, type-valid receipt contract.
+
+## What it cannot see
+
+The harness receives the scenario prompt, public tool schemas, emitted calls, dispatched tool results, and the declared output shape. It does not receive expected answers, hidden assertions, required-call sets, scorer results, or holdout secrets. It cannot fabricate a tool receipt, infer an unstated output value, turn a failed receipt into success, or bypass post-mutation verification.
+
+## State model
+
+Each dispatched tool call creates a receipt containing only its sequence number, tool name, canonical argument signature, success/failure classification, and state epoch. A successful mutation increments the epoch and opens a verification requirement. A successful verifier closes that requirement. Failed verification remains open while the model investigates and closes only after a later verifier succeeds.
+
+Duplicate suppression applies only within an epoch. Re-reading the same file after a mutation is therefore allowed because the underlying state may have changed.
+
+## Reporting contract
+
+Run `baseline` and `shiftedx-harness-v1` against the same model revision, server revision, sampler, reasoning mode, tool schemas, scenario order, and budgets. Report each profile separately with:
+
+- cases passed and total cases;
+- emitted and dispatched tool calls;
+- blocked duplicate and investigation-stall counts;
+- terminal correction and receipt-projection counts;
+- prompt/completion tokens and total wall time; and
+- weighted decode throughput when available.
+
+A harness-assisted improvement is a deployment-policy result, not evidence that the model weights became more intelligent. Promotion should require repeated complete trials under an unchanged public benchmark revision. Publish only sanitized aggregate and per-case ledgers; retain raw transcripts privately for audit.
