+`0fd7e2829449b052abf0078666669302923d77af`. + +This experiment asks one question only: how much of an actual inner Code Mode +tool invocation can reviewed same-process runner instrumentation observe without +patching OpenCode? + +## Result + +Stock OpenCode 2.0.23 supports a useful partial observation path: + +| Fact | Stock supported surface | Result | +| --- | --- | --- | +| unique inner invocation identity | runner-owned `tool.transform` wrapper allocates an ID when the decoded leaf handler is actually entered | **supported** | +| actual selected tool | wrapper is attached to the effective registered tool | **supported** | +| executable input | wrapper runs after core input decoding and receives the value passed to the leaf handler | **supported** | +| real outer `execute` binding | the real `Tool.Context` carries Session/message/outer CallID into each inner leaf | **supported** | +| start / handler-terminal ordering | runner observer sequence around the transformed leaf handler | **supported** | +| exact final value delivered to the Code Mode script | no supported public stock boundary exposes it with unique inner identity | **unsupported** | +| exact final error seen by the script catch path | no supported public stock boundary exposes it with unique inner identity | **unsupported** | + +The partial path is useful for proving that an inner call really entered a +particular tool with a particular decoded input. It is **not** sufficient for +assertions about the value/error ultimately observed by Code Mode. + +The experiment therefore reports the final-caller capability as: + +```json +{ + "status": "unsupported", + "reason": "stock_codemode_final_boundary_not_exposed" +} +``` + +No value is reconstructed from an earlier result. + +## Exact missing boundary + +There are three distinct boundaries in stock 2.0.23. + +### 1. Public transformed leaf handler + +`packages/core/src/tool/runtime.ts` decodes input and then calls the registered +tool's `execute(decoded, context)`. + +A runner-owned `ctx.tool.transform(...)` wrapper can therefore allocate a fresh +per-call ID at a real execution boundary and observe: + +- the effective tool registration; +- decoded/executable input; +- the real Session ID, agent, message ID and outer `execute` CallID carried in + `Tool.Context`; +- handler return or throw; +- start and handler completion order. + +This works for identical concurrent calls because correlation is carried by the +wrapper's own per-invocation state. It does not pair calls by input, FIFO order, +tool name, or completion order. + +But the handler result is still early. After it returns, core may: + +1. encode/normalize the tool output; +2. run public `tool.execute.after` hooks, which may mutate the result; +3. normalize content; +4. let the Code Mode adapter choose structured output vs text/null fallback; +5. validate Code Mode output; +6. JSON stringify/parse the value before it crosses into the confined script. + +So the transform wrapper cannot claim its handler terminal is the script-visible +terminal. + +### 2. Public core `tool.execute.after` + +`packages/core/src/tool.ts` exposes a later hook with the core result/error. + +This is also insufficient for exact Code Mode correlation: + +- every inner Code Mode call receives the same `Tool.Context.id` as the outer + model-visible `execute` call; +- therefore concurrent identical inner calls have the same public CallID; +- the hook runs before Code Mode's own final output decode/JSON round trip; +- failures that escape the core Tool.Error path need not produce this hook even + though Code Mode later converts the failure for the script. + +Using input equality, FIFO order, object identity, or completion order to join +this hook back to wrapper records would invent a correlation contract that stock +OpenCode does not provide. + +### 3. Private Code Mode terminal and catch materialization + +The last success-value boundary exists inside `@opencode/codemode`. + +In `packages/codemode/src/tool-runtime.ts`, `hooked(...)` runs +`hooks["tool.after"]` from `Effect.onExit` around the Code Mode execution body. +For a successful call, this happens after output decoding and the JSON +stringify/parse round trip, so its `CallResult.value` is the plain value that the +tool promise will deliver into the interpreter. + +However, `packages/core/src/codemode/tool.ts` constructs Code Mode with only +OpenCode's private `progressHooks(record)`. That hook uses the internal call +object only to update UI rows and publishes name/input/status. It does **not** +publish the success value, and stock plugin APIs provide no supported way to add +another Code Mode hook there. + +The error path is later still. A failed tool promise reaches the interpreter and +`packages/codemode/src/interpreter/interpreter.ts` materializes the failure into +the JavaScript error value bound by a `catch` clause. There is no plugin/runtime +hook at that materialization boundary either. The private Code Mode `tool.after` +can see the host-side failure before this conversion, but that is not the exact +JavaScript error object seen by the script. + +So stock exposes neither the final success value with public unique correlation +nor the final catch-path error representation.

The script asserts that it +receives `AFTER-MUTATION`. The transformed handler observer records +`BEFORE-MUTATION`.

This branch is based on the post-#52 target head `b10c52d50aaf0c038e77e80eaca3890347d5fa82`. ## Defect Stock OpenCode 2.0.23 creates the model-facing Code Mode `execute` tool inside `Tool.snapshot`, after registration transforms have run. The integrated observer therefore did not emit a native observation for that real outer invocation. Inner records were linked only to an internal opaque token. That allowed the public native boundary to report complete/zero outer-`execute` observations while Code Mode had actually run. ## Correction - Observe the real model-facing outer `execute` invocation at stock `execute.before`. - Keep `session.tool.success` / `session.tool.failed` as terminal authority. - Bind Code Mode inner records to that observed outer invocation ID. - Reject dangling, wrong-tool, or identity-mismatched parents in canonical accounting/validation. - Strengthen provider-free acceptance checks for outer observation, exact parent resolution, identity agreement, non-zero native coverage, concurrency, and reverse completion. - Document that synthetic outer `execute` input is exact at `execute.before` but pre-`CodeMode.Input` decode. ## Scope No threat-model expansion.

The base now includes merged #54 (`b10c8e9`), which closes the authoritative outer Code Mode `execute` blocker. This PR is rebased directly on that commit and contains only the remaining authoritative-capture transport correction plus its regression coverage. Stock OpenCode remains **2.0.23**. No threat-model expansion. ## Blocker 1 — outer Code Mode `execute` **Closed in the base by #54 and revalidated here.** The current integrated runtime evidence: - observes the real synthetic outer `execute` at the supported stock `execute.before` boundary; - records Session, agent, message, real CallID, supported hook input, and a unique runtime invocation ID; - uses stock `session.tool.success` / `session.tool.failed` as terminal authority; - binds every inner Code Mode call to that exact observed outer invocation; - rejects dangling or identity-mismatched parents; - keeps exact Code Mode caller-finality explicitly unsupported. The Code Mode probe remains green after the capture-transport change. ## Blocker 2 — remove target-writable authoritative capture The production observer no longer uses: `/tmp/runtime/runtime-observer.jsonl` Authoritative observer records now cross the process boundary through a **runner-owned one-connection loopback stream**: 1. the runner binds an ephemeral listener on `127.0.0.1` immediately before the real OpenCode invocation; 2. the trusted observer connects during plugin startup; 3. the listener closes after accepting that one connection; 4. the observer removes the endpoint from `process.env` before evaluated tool subprocesses run; 5. sanitized observer records flow over the established stream; 6. the runner drains and validates those bytes through the existing canonical builder/validator/accounting path. A direct inherited memfd/FD was tried first, but stock `@opencode/cli@2.0.23` crosses an internal process boundary that does not preserve arbitrary extra descriptors. The one-connection stream keeps stock OpenCode unchanged and avoids filesystem authority without introducing security-platform machinery. Protection against a deliberately malicious same-process plugin remains explicitly out of scope. ## Tamper regression Provider-free acceptance includes an evaluated tool that spawns `/bin/sh` and: - creates the old capture path; - deletes it; - recreates it; - appends a forged observer record. The scenario passes only if the shell tamper completes, authoritative evidence remains complete/eligible, the real tamper tool is observed, and the forged invocation/tool never appears in `runtime_evidence`. ## Preserved - `opencode-eval-runner/runtime-evidence/v1`; - canonical builder / validator / accounting; - pre-sink credential sanitization; - stock Session terminal authority; - Code Mode exact caller-finality remains unsupported; - normal `invoke` behavior; - assertion-scoped eligibility; - stock OpenCode 2.0.23 only. No signing/HMAC, protected channel, remote PluginHost, capability broker, hostile-plugin isolation, or OpenCode patch is introduced. ## Validation Current clean head is based directly on merged #54 and is mergeable. - **CI #329 / run 37532684965 — PASS** - **95/95 Python tests** - stock Code Mode probe: **PASS** (`diagnostics_passed: true`) - OpenCode **2.0.23** - **Provider-free runtime evidence acceptance #43 / run 37532684985 — PASS** - all **11/11** scenarios: - native_success - native_error - code_success - code_caught_error - concurrent_reverse - delegation - timeout - interrupted - redaction - collector - capture_tamper - **Stock native observer integration #55 / run 37532684878 — PASS** - stock OpenCode 2.0.23 - capture complete - provider-free native observation ## Merge scope This PR is ready for review against `refactor/trusted-checkout-evidence`.

The runner is an isolated **invocation execution boundary**, not an eval-suite engine. This PR makes that contract explicit and documents every supported public invocation surface. ## Changes - add `docs/invocation-usage.md` as the authoritative usage/interface reference; - explicitly state that there is no input-JSON request API today; - document the invocation input contract: CLI/Action arguments plus prompt/system/config seed files; - document all **24/24 CLI options**, including defaults and transport applicability; - document all runner-specific environment overrides and recognized provider credentials; - document all **21/21 GitHub Action inputs** and defaults; - document Action precedence: repository `command` mode, direct invocation mode, and setup-only mode; - document which CLI capabilities are not exposed as direct Action inputs; - add a complete "ways to run" matrix; - clarify that eval cases/assertions/judging remain owned by the calling harness; - correct the stale README description of the current zero-inference plugin activation preflight; - link the complete reference prominently from README local and Action usage sections. ## Validation Cross-checked the docs against the current implementation: - CLI flags documented: **24/24** - Action inputs documented: **21/21** - runner-specific environment overrides documented: **8/8** Documentation only; no runtime or contract behavior changes.
