Claude a627fa5ac7 Log the no-setpoint rule as a decision to revisit, and widen the register
OI-02: the second of the three lines this system does not cross - no
recommended setpoints or operating parameters - is expected to come up as
a feature request. An Advisory answer gives evidence, ranges, outcomes and
documented limits, then defers to a competent person, and never returns a
number as the answer. There is a foreseeable case for allowing it, and the
conversation should start from what is built rather than from scratch.

The entry records where the rule actually lives, because it is a code path
and not a prompt instruction, so relaxing it is a change in four places at
once: AdvisoryAnswer's recommendation_given: Literal[False] and required
deferral in api/contracts.py, the classifier routing anything
partly-advisory to the class that refuses to advise, 14 Advisory cases in
the eval set, and 15 tests. It also records what has to be decided before
any of that is touched - who is accountable for the number, what evidence
is sufficient when the historian shows what happened rather than what the
plant can safely do now, and how a recommendation is told apart from a
documented limit on screen.

It is blocked by the OT/safety review of section 2 of the build spec,
which is still outstanding. That review will have the strongest opinion on
this rule of anything in the document, so the rule should not be relaxed
before it happens.

The register's header said it held work we "intend to do", and its
boundary table admitted only defects. OI-02 is neither: the rule works as
designed. Rather than let the register's rules and its contents disagree -
which is the failure this register exists to prevent - the header now
covers decisions we expect to revisit, and the table has a row for them
requiring the entry to be marked "not a defect".

Open issues — WRPS Plant Assistant

Work we own, and decisions we expect to revisit. One entry per issue, newest first. Nothing here is assigned yet; owners are set at handover.

What belongs here, and what does not

This repository has three other registers. Putting an item in the wrong one is how a repository ends up saying two different things about the same fact.

If it is... It goes in Not here
Waiting on somebody outside this project REQUESTS.md
A shortcut we consciously accepted BUILD-AI-CONTAINERS.md §14
Something already running, and its state current-state.html
A defect or gap we own and have not fixed here
A design decision we expect to revisit here, marked not a defect

Three rules:

  1. Anything in §14 is closed by decision. It was weighed and accepted. Do not re-open it here — caddy/ai-routes.caddy carries one such decision explicitly marked "do not re-raise this as a task".
  2. If an issue is a defect in something that already passed a phase gate, fixing it means re-running that gate. CLAUDE.md requires it; say so in the issue.
  3. Closed issues move to the bottom, they are not deleted. The register is part of the as-built record, and an issue with no trace of how it closed is worth less than one that was never raised.

OI-02 · The no-setpoint rule may need to become optional

Raised 2026-09-01 · Owner unassigned · Affects the product, not the build · Not a defect — the rule works as designed. Logged because it is a design decision that is expected to be revisited.

The second of the three lines this system does not cross is no recommended setpoints or operating parameters. An Advisory answer gives evidence, ranges, outcomes and documented limits, then defers explicitly to a competent person. It never returns a number as the answer.

There is a foreseeable case for allowing it — a recommendation is the thing an operator actually wants, and withholding it has a cost. This entry exists so that conversation starts from what is built rather than from scratch.

Where the rule lives. It is not a prompt instruction, so relaxing it is a code change in several places at once:

Enforcement point What it does
api/contracts.pyAdvisoryAnswer recommendation_given: Literal[False] — the contract cannot express a recommendation. A deferral string is required, and a scope banner is attached to every Advisory answer
api/classifier.py Advisory beats Historical; partly-advisory is advisory. Anything that could be read as advice is routed to the class that refuses to advise
eval/testset.jsonl 14 Advisory cases assert the refusal
api/tests/ 15 tests across contracts and classifier rules

What would have to be decided before it changes — none of this is a coding question:

  • Who is accountable for a number the assistant produces, once it stops deferring. Today the deferral is what keeps that answer unambiguous.
  • What evidence is sufficient. The rule exists because "best" depends on equipment condition and concurrent operations this system cannot see — the historian shows what happened, not what the plant can safely do now.
  • How a recommendation is distinguished on screen from evidence, so it cannot be misread as a documented limit.
  • Whether it applies to all parameters or a named subset, and who approves that list.
  • §2 of the build spec is still awaiting an OT/safety review. This rule is the largest single thing that review will have an opinion on. Do not relax it beforehand.

Blocked by the OT/safety review of spec/BUILD-AI-CONTAINERS.md §2, which is outstanding. Blocking nothing.


OI-01 · OpenPLC Editor is not installed

Raised 2026-09-01 · Owner unassigned · Affects the demo plant, not the assistant

The OpenPLC Editor — a desktop tool published by the OpenPLC project, installed on a workstation — is the application used to author and compile the IEC 61131-3 program that openplc-runtime executes. It is not installed anywhere. It talks to the running container over its REST API on port 8443, bound to 10.0.0.17.

Why it matters. openplc-runtime is live control for this demo: CLAUDE.md and BUILD-AI-CONTAINERS.md §4 both forbid reconfiguring it as a side effect of other work. Without the Editor there is no way to author, review or compile the control logic — and no reviewable source for it in or beside this repository. The program exists only inside the container. If the container is lost, so is the logic.

What port 8443 is — probed read-only on the host 2026-09-01, because two earlier statements in the build spec called it a web UI and were wrong:

Server: Werkzeug/3.1.8 Python/3.11.2
/  /login  /index.html  /programs  /status  /runtime   -> 404
/api/v1                                                -> 401 Unauthorized

An authenticated REST API. No browser interface. Both build-spec statements were corrected in the commit that raised this issue.

Open questions to settle when this is picked up.

  • Which workstation. Not lin001 — the Editor is a desktop application. Not cicore1CLAUDE.md forbids installing anything on it. That leaves an engineering workstation with VPN or LAN reach to 10.0.0.17:8443.
  • Credentials for /api/v1, which currently answers 401. Not held by this project.
  • Whether the PLC program goes under version control, and where. This is the part that closes the "logic exists only in the container" gap, and it is the reason this issue is worth more than "install a tool".

Blocked by nothing. Blocking nothing today — the demo runs.
