drafts: true📝 WalkthroughWalkthroughAdds a resource-policy verifier with canonical parsing, strict lineage validation, isolated digest-pinned Docker execution, bounded output handling, artifact validation, and two CLI entrypoints. ChangesResource Policy Verification
Estimated code review effort: 4 (Complex) | ~60 minutes Merge Risk: 🟠 High · up to The runner can currently report that a command succeeded even when it never executed, while its mount validation uses an incompatible Docker schema and CI is not green. Caller-selected host paths and failure cleanup also need explicit safety boundaries, so this PR is not merge-ready until the correctness, build, and isolation issues are fixed.

Inline comments:
In `@tools/af02-verifier/src/resource.rs`:
- Around line 902-1012: Add negative counterexample tests covering
validate_resource_policy for an invalid schema or runner_image_digest and an
out-of-bounds numeric field. Add validate_lineage tests rejecting BOOTSTRAP with
a predecessor and REBASE without one. Add synthetic serde_json::Value fixtures
for verify_runtime_inspection rejecting NetworkMode other than none and writable
source mounts, including the expected Tmpfs and Mounts representations.
- Line 1: Remove the unused std::collections::BTreeSet import from the resource
module, leaving the remaining imports and implementation unchanged.
- Around line 215-221: Update validate_directory to reject canonicalized source
and output paths containing commas or equals signs before constructing the
Docker --mount specifications. Ensure invalid paths return the existing
validation error path, while valid paths continue using source and output in the
mount arguments.
- Around line 195-197: Update run_bounded to require Docker CLI version 20.10.0
or newer before invoking the command with --pull=never. Preserve --pull=never
for offline_required executions, and provide a clear failure when the detected
CLI is older.
- Around line 308-320: Update the captured-status validation in run_bounded so
exit code 125 is tolerated only when the inspected container State.Status is
classified as exited and stderr contains the AF02_RESOURCE_PROBE_FAIL= marker;
otherwise return ResourceError::RuntimeInspection. Preserve normal matching
exit-code handling, and fail closed when the container status cannot be read or
classified.
- Around line 569-574: The verify_runtime_inspection mount validation must
follow Docker’s inspect schema: read Mounts from the top-level inspect object,
use each entry’s RW field, and compare it with the inverse of the expected
read_only value for both bind-mount checks. Add a synthetic inspect fixture
covering these mount fields and validation paths in
tools/af02-verifier/src/resource.rs at lines 569-574 and 591-601.

AF-02 Stack A0 — T015 resource runner infrastructure
Stack predecessor:
This is a stacked A0 infrastructure candidate. It does not modify
resource-policy.json, does not execute fuzz/property/coverage/mutation evidence, and does not claim dependent closure.T015 implementation

The canonical resource policy remains the earlier BOOTSTRAP policy and is not changed in this candidate. No same-candidate dependent evidence is included. This PR remains draft and is not merge-authorized while its stack predecessors are non-canonical or review governance is unsatisfied.
Qualification
This initial implementation head is intentionally unqualified. It will be formatted, compiled, linted, unit-tested and subjected to a real pinned-container negative-probe smoke before any exact-head qualification claim.
Summary by cubic
Adds a bounded OCI resource runner to the AF-02 verifier so commands execute in a digest-pinned, fail-closed Docker environment. Adds
