- **Version 0.6.1**, on [PyPI](https://pypi.org/project/ctrlrun/), Python 3.11 and later.
- **4,999 tests**, every version specified before it was written and every requirement mutation-tested.
- **15 guarantees you can check in your own setup**, with `ctrlrun verify` against your policy, on your store's backend, in a scratch store it creates.
- **Version 0.7.0 is in development**; [PyPI](https://pypi.org/project/ctrlrun/) has 0.6.1. Python 3.11 and later.
- **5,164 tests**, every version specified before it was written and every requirement mutation-tested.
- **16 guarantees you can check in your own setup**, with `ctrlrun verify` against your policy, on your store's backend, in a scratch store it creates.
- **One host: a file.** SQLite, no server, no ops. **Many hosts: Postgres**, the same guarantees, graded by the same suite.
- **Soaked for 20m 0s on postgres**: 889,735 actions, 0 unattributed ambiguous outcomes, positive control fired. Nothing here establishes what only accumulates over days. [What it does not establish](https://ctrlrun.dev/docs/production/soak).
- **Each receipt carries the hash of the one before it**, so an alteration is detected and named.

and a second implementation of SPEC-v0.1 §5.5's asymmetry, which is the one rule in this
codebase that must not drift.

v0.7 narrows that asymmetry on one path, in both places at once so they cannot drift apart:
**a continuation leg never records `FAILED`**. A continuation exists only because the remote
answered once already and is holding the exchange, so nothing on the second leg can truthfully
say the remote did nothing. `Control.resume` opens its executor run already marked, so
`transport.py` will not claim there, and the gateway refuses `FAILED` for every path that could
reach it on a continuation, an operator's `not_executed_on_error` included. An executor's own
`NotExecuted` is still believed; what changed is that nothing in the library hands it one
(SPEC-v0.7 §12.2.12).

The same holds for authority (v0.3). `authority.py` reads the store through the `StateStore`
protocol and **writes nothing and appends nothing**: `Authority.evaluate` returns a result and
`plan_delegation` returns the record it *would* write, and `Control` performs every write and

start comparing equal to `1`. Policy still cannot see a principal: `agent_eq` and every other
reserved name are still refused at load (§4.7).

**The sentence that followed that one said *`policy.py` does not import `authority.py`, so there
is no cycle*, and a v0.7 review found it is no longer true.** `policy.py` reaches
`authority.py` from inside two functions, `state.py` imports `receipt.py`, `receipt.py` imports
`policy.py` and `authority.py` imports `state.py`, so there is a cycle:
`state` → `receipt` → `policy` → `authority` → `state`. It does not break `import ctrlrun`,
because the two edges out of `policy.py` are function-level and run after every module is
loaded, which is exactly why it went unnoticed. What it costs is this section's own rule: with
the cycle in place *dependencies point downward only* is a statement about import order rather
than about the module map, and the map is what a reader uses to work out what may know about
what. Whether to break it, and which edge to break, is a **named item before v1.0** on the
roadmap rather than a change made in a release pass. Recorded 2026-09-12.
