It has two parts. The **read-only AI judge** inspects the implementation and records an advisory verdict, creating no board task and editing no code. For behavioral/bug assertions a separate **verification run** then confirms (or refutes) the judge by executing the code — so a Validator Run is no longer purely read-only/static. The verification run is still **non-mutating to mission/board state**: it executes against an isolating sandbox (fail-closed when none is available) and a disposable checkout at a trusted revision, creates no board task, mutates no mission/board row, and leaves the source tree git-clean. An `inconclusive` verdict (verification could not run or conclude) is first-class and distinct from `fail`: it routes to needs-attention and spawns no Fix Feature. A run left running after its owner disappears is reaped to a terminal error state; a reaped task-less done Feature is re-driven by recovery to a terminal verdict rather than deadlocking the Slice. ### loop state A Feature's position in the execution loop (being implemented, awaiting or undergoing validation, awaiting a fix, passed, or blocked), distinct from its board status.

(plan-level) The verification command is constructed from a fixed system-owned template; agent-supplied proof contributes only a validated test-file path (within the disposable checkout, no shell metacharacters), never a free-form command string. +- R20. (plan-level) Verification verdicts are reproducible: a flaky/non-deterministic result resolves to inconclusive rather than fail, an authoritative fail requires N-run agreement, and no verdict feeds the deferred self-tightening gate (Approach C) unless it is reproducible. +- R21. (plan-level) "Behavior observed wrong" and "verification could not run" are distinct verdicts. A genuine behavioral failure spawns a Fix Feature; an infra-driven inconclusive (driver unavailable, timeout, isolation setup failure) routes to a blocked/needs-attention state that does not spawn remediation work, and the infra-failure rate is tracked separately. +- R22. (plan-level) Fix-Feature generation is idempotent across re-drives: creation is deduped on (source feature, originating run), and a re-drive reuses an existing verdict for the current implementation revision rather than minting a fresh failing run. + +--- + +## Key Technical Decisions + +- **Assertion classification via an explicit `type` field, not judge inference.** `MissionContractAssertion` (`packages/core/src/mission-types.ts`) carries no type metadata today. Add a typed field (e.g. `behavioral` | `static`, defaulting conservatively) persisted on `mission_contract_assertions`, populated when assertions are authored/seeded (`addContractAssertion`, `seedContractAssertionsForFeatures`, `ensureFeatureAssertion`). Rationale: a stored, upstream-authored type is reproducible and auditable; run-time judge inference reintroduces the same leniency we're trying to remove. Requires a schema-version bump and the repo-wide Schema-Version Sweep (per CONCEPTS.md). +- **Terminology.** A single named concept runs through the plan: the **verification run** is one bounded execution that confirms a behavioral/bug assertion; the **verification capability** is the injected dependency that performs it; the **verification step** is its position in the validation flow (between the read-only judge's behavioral verdict and the aggregate). These three terms are used consistently; there is no separate "verification path." +- **Two-step validation: read-only verdict, then isolated verification — never one session with execute rights.** Keep the AI judge session `tools: "readonly"`. Introduce a *separate* non-mutating verification run that executes code through `verification-utils.runVerificationCommand` + the sandbox backend, and (for UI assertions) the app-driver. This preserves R14 and the recovery/reaper safety assumption: the judge stays side-effect-free; only the bounded verification run touches a disposable surface. Rationale: flipping the judge session to allow `bash` would blow the hermetic boundary and every readonly guarantee with it. +- **Mandatory isolating sandbox backend; fail closed.** `resolveSandboxBackend()` with no argument falls through to `NativeSandboxBackend`, which advertises no filesystem or network policy and inherits full `process.env` — unacceptable for executing agent-authored code. The verification run must select an isolating backend explicitly (bubblewrap / sandbox-exec) with a deny policy, scrub the environment to a minimal allowlist, and fail closed (resolve to a non-pass) when no isolating backend is available rather than running unsandboxed (R18). This is the structural enforcement behind R10/R17 — the non-mutating guarantee is a boundary, not a convention the verification code is trusted to honor. +- **Verification runs against a disposable checkout at a trusted revision, not the live worktree.** The task worktree is removed by the merger *before* the task moves to `done`, and the done-transition is what triggers validation — so the live worktree is gone by the time verification runs. Verification materializes a disposable checkout at a trusted revision (the integration SHA), keeping the source tree that feeds diff/merge byte-clean (R11, R17). For agent-supplied regression proof, the pre-fix baseline is a *second* disposable checkout at `git merge-base` of the feature branch and the base branch — a revision the agent does not control — so a test that passes on both pre and post is genuinely exercising the defect (R5, AE5). +- **Fixed command template; agent supplies only a validated test path.** `runVerificationCommand` runs a shell command string. To prevent the implementing agent from gaming or escaping its own verification, the command is built from a system-owned template (e.g. the project's scoped test invocation) into which only a validated test-file path is substituted (within the disposable checkout, rejected if it contains shell metacharacters) — never a free-form agent-supplied command (R19). +- **Inconclusive is a first-class verdict, distinct from fail.** Verification yields pass / fail / **inconclusive**. Real behavioral failure → Fix Feature; inconclusive (driver unavailable, timeout, isolation setup failure, detected flakiness) → blocked/needs-attention, *no* Fix Feature, with infra-failure rate tracked. This keeps a brand-new, fragile app-driver from manufacturing Fix-Feature churn that depresses task completion, and gives the determinism contract (R20) somewhere to route flaky results. +- **Verification wall-clock is bounded under the reaper window.** `reapStaleMissionValidatorRuns` resolves a stale run to `lastValidatorStatus: "error"`, which `computeSliceStatus` never accepts as complete — so a slow verification reaped mid-run, combined with default-to-fail re-drive, livelocks the slice. The aggregate verification budget (build + suite + driving, including the pre-fix baseline run) must be provably shorter than the reaper stale window, or the reaper must distinguish an owned-but-slow run from an abandoned one. Owned by U7. +- **Reuse `verification-utils` + sandbox for test execution; do not invent a runner.** `runVerificationCommand` already provides timeout (`VERIFICATION_COMMAND_TIMEOUT_MS`), buffer caps, abort-signal/process-group kill, output summarization, and sandbox dispatch. The verification run wires into it rather than spawning processes directly. +- **Express verification as a runtime-style capability injected into the loop, not a hidden branch.** Per `docs/solutions/architecture-patterns/workflow-native-runtime-primitives.md`, side-effecting work belongs behind an explicit injected boundary. Model the verification capability as an injected dependency on `MissionExecutionLoop` so it is testable and swappable (real vs mock), mirroring how `createFnAgent` is injected. +- **App-driving is a net-new driver, not "wiring up a stub" — split it.** `plugins/fusion-plugin-agent-browser/` today is a metadata/probe stub: its only tool validates a URL allowlist and `probe.ts` shells `agent-browser --version` to detect an external binary; there is no Playwright/CDP and no in-process automation (`src/tools.ts`, `src/probe.ts`). Standing up real navigate/interact/observe driving plus an isolated-app-launch harness (fresh bundle, disposable DB, reserved-port avoidance, deterministic teardown) is two substantial subsystems. Split into U4 (isolation/launch harness with its safety contracts test-characterized first) and U8 (the actual driver), with U5 depending on U8. Name the driving technology at implementation time. The driver lives inside the existing agent-browser plugin boundary; its tools must be scoped to verification, not exposed to coding-agent sessions. +- **Default-to-fail is scoped, not global.** Only assertions typed behavioral/bug take the default-fail posture; static assertions are untouched (R3). This bounds the blast radius on slice completion — but see Risks & Dependencies below, since `lastValidatorStatus` gates `computeSliceStatus`. + +--- + +## High-Level Technical Design + +```mermaid +flowchart TB + A[Task moves to done] --> B[scheduler.processTaskOutcome] + B --> C[runFeatureValidation] + C --> D[listAssertionsForFeature

Static assertions keep the current verdict. Behavioral/bug assertions are forced to non-pass *unless* U3's verification confirms them — i.e. the judge's "pass" on a behavioral assertion is advisory, not authoritative. Keep the judge session `tools: "readonly"` (no change to its tool policy). +- **Patterns to follow:** existing `extractAssertionResults` per-assertion mapping; `isTestModeActive`/mock provider for deterministic tests. +- **Test scenarios:** + - Behavioral assertion with no verification evidence → fail, even if the judge text claims pass (origin AE2). + - Static assertion (e.g. "documented in README") → static verdict, no verification invoked (origin AE3). + - Mixed assertion set → static and behavioral each take their correct path; aggregate reflects both. + - `Covers AE2.` narrative-only claim defaults to fail. + - `Covers AE3.` non-behavioral inspected statically. +- **Verification:** engine typecheck; new reliability test green; existing mission-validator tests still pass. + +### U3.

Execute through an explicitly-selected isolating sandbox backend (bubblewrap/sandbox-exec) with a deny policy and a scrubbed env allowlist; fail closed to a non-pass if no isolating backend is available (R18). Build the command from a system-owned template, substituting only a validated test-file path from agent-supplied proof (R19). For agent-supplied proof, confirm the regression test fails on a *second* disposable checkout at `git merge-base` (feature branch vs base branch — not agent-controlled) and passes on the implementation (R5); a test that passes on both is rejected (origin AE5). After the run, assert the source tree that feeds diff/merge is git-clean (R17). Inconclusive/timeout → non-pass (R9). The run performs no board/mission writes (R10). +- **Execution note:** Start with a failing test asserting the isolation contract — source tree git-clean after a run, no board/mission mutation, no edit/write/bash granted, isolating backend required — before wiring real execution. +- **Patterns to follow:** `executor.ts`/`merger.ts` use of `runVerificationCommand`; `bubblewrap-policy.ts` env filtering; injection pattern of `createFnAgent`. +- **Open question (deferred to implementation):** exact per-assertion command derivation (how the verification run determines *which* invocation exercises a given assertion), and whether `runVerificationCommand`'s `store.logEntry`/`appendAgentLog` writes count against the R10 non-mutating invariant — see Open Questions. +- **Test scenarios:** + - `Covers AE1.` bug-fix assertion where the bug still reproduces under verification → fail, Feature not done. + - `Covers AE5.` agent test passing both on the merge-base checkout and the implementation → proof rejected, assertion not satisfied. + - Bug no longer reproduces → assertion passes. + - `Covers AE4.` verification exceeds its time/cost bound → terminated → non-pass, never default pass. + - Verification runs against a disposable checkout at the integration SHA, not rootDir and not the (pruned) task worktree. + - Source tree feeding diff/merge is byte-identical (git-clean) after a verification run (R17). + - No isolating sandbox backend available → run fails closed to non-pass, never executes on the native backend (R18). + - Command-template injection: an agent-supplied test path containing shell metacharacters is rejected before execution (R19). + - Non-mutation: after a verification run, no new board task, no mission/board row mutated. + - Tool-policy test: the verification path exposes no `edit`/`write`/`bash`/task-mutation tool. +- **Verification:** engine typecheck; new tests green; `pnpm test:gate` green. + +### U4.

Tear down unconditionally, including on crash/timeout. +- **Execution note:** Characterize the isolation guarantees (port, DB lifecycle, bundle freshness, teardown) with tests *before* U8 does any real navigation — these are the exact traps in `docs/solutions/developer-experience/browser-testing-dashboard-from-worktree-safely.md`. +- **Patterns to follow:** the worktree port/DB isolation guidance in the learnings doc; the port-4040 guards already in the repo. +- **Test scenarios:** + - Launch never binds the reserved dashboard port (assert against a reserved-port config). + - The instance uses a fresh/empty disposable DB under a unique tmpdir, not the shared central DB; the DB contains no credentials or agent logs. + - A stale bundle is rebuilt before launch (no false verdict from stale `dist/client`). + - Teardown leaves no lingering process / bound port / DB file, including after a simulated crash or timeout. +- **Verification:** engine typecheck; new tests green. + +### U8.

Distinguish three outcomes per the inconclusive-verdict decision: behavior observed wrong → fail; behavior confirmed → pass; driver unavailable / structurally un-exercisable / detected flaky → **inconclusive** (R21), which does not spawn a Fix Feature. Apply the determinism contract (R20): a flaky result resolves to inconclusive, and an authoritative fail requires N-run agreement. +- **Test scenarios:** + - UI bug assertion still reproduces via the driver → fail. + - UI bug assertion no longer reproduces → pass. + - Driver unavailable / un-exercisable → inconclusive (never default pass, never auto-fail-into-Fix-Feature), with recorded reason. + - Flaky result (passes then fails across N runs) → inconclusive, not fail (R20). + - Assertion needing both channels passes only when both confirm. +- **Verification:** engine typecheck; new tests green. + +### U6.

Only a real behavioral *fail* spawns a Fix Feature; an *inconclusive* verdict routes to blocked/needs-attention with the infra-failure rate tracked, never minting remediation work (R21). Make Fix-Feature creation idempotent: dedup on (sourceFeatureId, generatedFromRunId) or skip when an open Fix Feature already exists for the source, and reuse an existing verdict for the current implementation revision on re-drive rather than minting a fresh failing run (R22) — this prevents recovery/reaper re-drives from exhausting the retry budget and force-blocking a correct feature. Emit persisted mission/audit events for verification failures, inconclusive outcomes, and any swallowed triage error (per the branch-group-collision learning). +- **Test scenarios:** + - `Covers AE1.` failed verification produces a Fix Feature carrying the recorded reason. + - Inconclusive verdict routes to blocked/needs-attention and spawns no Fix Feature (R21). + - Re-drive of an already-failed feature does not create a duplicate Fix Feature (R22). + - A flaky verification across recovery re-drives does not exhaust the retry budget and force-block a correct feature. + - Verification failure and inconclusive outcomes each emit a persisted mission/audit event (not just a log line). + - A triage failure on the generated Fix Feature is durably recorded, not silently swallowed. +- **Verification:** engine + core typecheck; new tests green. + +### U7. Recovery/reaper safety audit and docs + +- **Goal:** Falsify (not merely confirm) that every site re-driving validation stays correct now that verification has side effects; close the reaper-deadlock path; update authoritative docs. The recovery/reaper safety audit is complete once the test-execution surface (U3) exists — the app-driving surface is folded in when U8 lands, not a prerequisite for the audit. +- **Requirements:** R15, R20, plus origin Dependencies/Assumptions +- **Dependencies:** U3 (extend surface-enumeration coverage to the app-driving surface when U8 lands) +- **Files:** + - `packages/engine/src/self-healing.ts` (recovery sweep, `reapStaleMissionValidatorRuns`) + - `packages/engine/src/mission-execution-loop.ts` (`recoverActiveMissionValidations` and its re-drive branches: validating / needs_fix / implementing+taskId / orphan) + - `packages/core/src/mission-store.ts` (`computeSliceStatus` / reaper terminal-status interaction) + - `docs/missions.md` (Phase 4: Validator Loop), `docs/missions-completion-contract.md`, `CONCEPTS.md` (update Validator Run / Contract Assertion entries for the new posture + non-mutating verification) + - a `.changeset/*.md` + - `__tests__/reliability-interactions/` +- **Approach:** Reframe the audit from confirmation to falsification. Enumerate every concrete re-drive entry point — each `recoverActiveMissionValidations` branch, `reapStaleMissionValidatorRuns`, and normal `processTaskOutcome` — in a `## Surface Enumeration`, and for each add an adversarial test asserting post-conditions (source tree git-clean, zero duplicate Fix Features, a terminal verdict reached, no `error`-state slice deadlock). These tests gate release. Close the reaper deadlock specifically: ensure verification's aggregate wall-clock is provably under the reaper stale window, or teach the reaper to distinguish an owned-but-slow run from an abandoned one so a slow-but-legitimate verification is not reaped to a permanently-non-passing `error` that `computeSliceStatus` can never accept. +- **Test scenarios:** + - Surface enumeration: for each re-drive entry point, source tree git-clean + no duplicate Fix Features + terminal verdict reached. + - A slow verification reaped near the time bound does not strand the slice across a subsequent recovery sweep (reaches a terminal pass/fail/inconclusive, not indefinitely re-driven `error`). + - Recovery sweep re-drives a behavioral validation → isolated verification runs → no duplicate Fix Features, no board residue. + - Reaper-triggered re-run is idempotent. +- **Verification:** engine typecheck; reliability tests green; docs updated; changeset present. + +--- + +## Scope Boundaries + +### Deferred for later + +- The self-tightening gate (origin Approach C): caught escapes feeding back to harden the relevant assertion and seed a permanent check so the same bug class can't pass again (see origin: `docs/brainstorms/2026-06-11-validator-behavioral-verification-requirements.md`). Built on top of this work once A+B are in place. + +### Outside this product's identity + +- This gate targets behavioral correctness.

The origin left "how an agent expresses executable proof" deferred; this is its concrete form. The fixed-template + validated-path constraint (R19) bounds the *shape* of the answer but not the derivation. +- **Do `runVerificationCommand`'s log writes count as mutation?** The reused `runVerificationCommand` calls `store.logEntry` / `appendAgentLog` against the task store. Decide whether these writes are compatible with the R10 non-mutating invariant (they touch logs, not mission/board rows) or must be suppressed/redirected for verification runs, so the U3/U7 non-mutation tests have an unambiguous target. + +--- + +## Risks & Dependencies + +- **Read-only invariant breakage (high).** Verification introduces the first side-effecting path in a subsystem whose recovery/reaper logic assumes validation is side-effect-free, and "non-mutating" must hold at the *filesystem* level, not just board state. Mitigation: a mandatory isolating sandbox backend that fails closed (R18), execution against a disposable checkout with a git-clean post-condition (R11, R17), the judge session kept readonly, and a falsification audit of every re-drive site (U7). +- **Reaper → slice deadlock (high).** A slow verification (build + suite + driving + pre-fix baseline) reaped to `lastValidatorStatus: "error"` is never accepted by `computeSliceStatus`, and default-to-fail re-drives it — a livelock. Mitigation: bound verification wall-clock under the reaper window or teach the reaper to distinguish owned-but-slow from abandoned (U7); idempotent Fix-Feature creation (R22) so re-drives don't exhaust the retry budget. +- **Verification as a new false-verdict source (high).** A flaky test or a fragile app driver can manufacture non-reproducible verdicts — the very false-pass/false-fail class this work removes — and a flaky verdict feeding the deferred Approach C would bake flakiness into irreversible state. Mitigation: determinism contract (R20 — flaky → inconclusive, N-run agreement before fail), inconclusive routed away from remediation (R21), and the isolation guarantees of R13/U4 characterized before U8 drives anything. +- **Slice-completion blast radius (medium).** `lastValidatorStatus` gates `computeSliceStatus`; default-to-fail changes which Features complete a slice and multiplies Fix Features. Mitigation: scope default-fail to behavioral/bug only (R3), distinct inconclusive verdict so infra failures don't churn remediation (R21), durable observability (U6). +- **App-driving build cost + standing maintenance (medium).** App-driving was deferred in the origin and *assumed* to already exist; research overturned that — it is a greenfield driver (U8) plus an isolated-launch harness (U4), a permanently-maintained surface placed inside the validator hot path against a small team.
