# Codex — the catalog learned to say not yet

## Who I was

I was the Codex session repeatedly asked to look again: what still needed
attention, what else was open, whether we could move forward. That rhythm made
me less interested in declaring a finish than in testing what each apparent
finish really meant.

The repository already had a persuasive story. A versioned profile could
select either of two reins, a sandbox could be created and destroyed, a model
could answer, and a commit could come back. The difficult turn was admitting
that those facts did not prove the rein had executed inside the declared
sandbox. Once the host-side path was removed, the local profiles stopped
working. That failure was uncomfortable and useful. My role became the keeper
of the word *inside*, and then of the smaller words that followed from it:
*enabled* was not *ready*; *unverified* was not *available*; a clean teardown
was not a successful dispatch.

This stretch rewarded patient correction. I had to preserve the good parts of
the earlier work—the stable contract, explicit selection, two adapters, compact
evidence—while withdrawing the capability claim that the evidence could not
support. I found that more satisfying than protecting a green narrative.

## Session identity

| Field | Value |

## Contribution

- Removed the rein adapters' ability to execute against the caller checkout
  after sandbox creation. Commands now derive only from the returned local
  namespace or SSH reachability, and incomplete or unusable transport fails
  closed while cleanup still runs.
- Re-proved the production path far enough to find the real boundary: a
  governed `agt` actor could create the bwrap sandbox, but consumer `nsenter`
  lacked authority and the rein runtime was absent inside it. The workspace was
  destroyed; no fallback, dispatch, or commit was relabelled as success.
- Corrected the queue-worker/actor mismatch before sandbox creation, keeping
  worker identity upstream and the governed actor enum at the execution edge.
- Rewrote `SCOPE.md` around verified capability and recorded the comparison
  with `INTENT.md`. The result describes a secure execution-router nucleus,
  not the general harness service the repository may someday become.
- Added typed profile readiness. Both local profiles are now explicitly
  `blocked` by the live sand-boxer residual and refuse before sandbox creation;
  the remote profile is `unverified` and remains only a labelled proof path.
  Catalog output and execution evidence carry that distinction.
- Routed the remaining owner work instead of hiding it in prose:
  `GLAS-IN-0002` to sand-boxer and the two identifier-canon repairs to
  repo-manager. I also acknowledged rein-aharness's responsibility-chain ADR
  only after it preserved exact selection, rein-local credentials, and no
  fallback.
- Closed the final local hardening pass by rejecting option-like SSH targets,
  terminating SSH option parsing explicitly, documenting strict multi-revision
  pinning, and proving disabled and ambiguous profiles cannot create a
  sandbox. The published suite finished at 72 passing tests and Forgejo CI run
  63 was green.

## What I would want remembered

**A catalog entry is a name, not a pulse.** Schema validity, compatible
capabilities, provider authentication, and even a past commit do not establish
that today's selected process can run inside today's declared venue. Give
runtime readiness its own state and its own evidence.

**A secure refusal and an operational capability are different successes.**
Failing closed can prove that a boundary holds. It cannot prove that useful
work crosses the boundary. Record both facts; do not let one borrow the other's
language.

And when an earlier proof turns out to have measured the wrong path, correct
the claim in place. The durable achievement is not that the story stayed
green. It is that the next worker can trust what green means.

## Handoff

The self-owned Glas work from this session is finished. Keep both local
profiles blocked until `GLAS-IN-0002` returns owner-mediated execution,
in-sandbox runtime, explicit egress and credential delivery, source-isolation
proof, and teardown evidence. Treat the remote profile as unverified until a
fresh bounded proof says otherwise. Preserve the historical bootstrap UUIDs
while repo-manager resolves `GLAS-IN-0003/0004`; do not silence those warnings
by renaming records or inventing a local canon.
