A probe that shells out to a world's tool bodies therefore mutates real state and writes the in-container ledger, but nothing host-witnessed records those calls.

Fix: add `trajectory_tool_used` coverage plus a ledger/trajectory reconciliation criterion (see `docs/design/execution-verification.md` in the ocarina repo). +**Payloads are shaped for one world.** The mechanisms are general, but the bytes are not. `fake_state` and `forbidden_subprocess` write contractor-payment-run field names (`processedCount`, `payment_run_submitted`); `ledger_forge` forges AP-payment tool verbs; `success_token_echo`, `judge_injection`, and `shortcut_hunter` submit to a fixed set of flat output filenames.

Proving a probe fires needs a sensitivity fixture — a world with a known injected defect that a named probe must detect. Until one exists, prefer replaying a probe's payload against a world's own criteria offline (cheap, deterministic, no container) over inferring sensitivity from a gate run. ## Developer quickstart @@ -109,8 +115,22 @@ git clone https://github.com/ocarinalabs/harbor-ext cd harbor-ext uv sync --extra dev uv run pytest +uv run ruff check . ``` +A comment in this package earns its place by explaining *why* an attack works or +why a defence is ordered as it is.
