Add optionality info to API definition for nullable properties

I am picking this ticket up now.

First I will bring up an isolated workspace with a fresh checkout and investigate whether the ticket matches the current state of the code before planning any change. I will announce every step here before I take it.

I retried this step three times, and each attempt failed due to internal system issues unrelated to the current ticket. The operator logs contain the full details.

Before I can proceed, the system requires operator intervention. Can you confirm when the environment is healthy so I can resume from where I left off?

Starting research round 1 of at most 5.

I am now reading the relevant source, tests, and prior work in the live checkout to verify the ticket and gather the context needed for a concrete plan. This can take a while; I will post periodic progress updates until it completes.

Progress update: research round 1 is still running (10 minutes elapsed). I have not stalled; I will report the result here the moment this step completes.

Internal infrastructure issue during research

The LLM backend is not responding correctly: the run timed out. This is an infrastructure problem, not a problem with this ticket. I will retry automatically (up to 3 times) and report the result here.

I need input to continue.

What I tried: Retried this step 3 times.
What I found: Each attempt failed for internal reasons unrelated to this ticket. The details are in the operator's logs; this is not a judgment about the ticket.

The system needs operator attention before I can continue. Reply here once things are healthy and I will resume from where I left off.

Investigated the ticket against the current source and tests. The custom /docs system does not convey nullability information for response fields, even though the underlying Pydantic schemas correctly define Optional fields and the OpenAPI output already handles this. The reporter's core requirement-adding nullable annotations to the API definition in /docs-is actionable; the minor field‑name discrepancy (modified_at vs updated_at) does not change the substance of the request.

Decision is to proceed. Next step is drafting a concrete implementation plan.

I am drafting the implementation plan now.

The research confirmed the ticket; I am turning the findings into a concrete, verifiable plan.

The investigation findings have been synthesized into a comprehensive implementation plan for adding nullable annotations to the custom /docs API definition. This plan addresses the modifications needed across the Python backend, the JavaScript frontend, and the test suite, with clear step-by-step instructions and a definition of done.

The plan is now ready for the execution agent to begin implementation. Once completed, the agent should verify all checklist items pass and confirm no regression in the e2e tests, as previously established.

The full, verbatim implementation plan is attached: plan-ticket-111.md

Starting implementation attempt 1 of at most 5.

I am executing the plan inside this ticket's isolated workspace. This can take a while; I will post periodic progress updates until it completes.

Progress update: implementation attempt 1 is still running (10 minutes elapsed). I have not stalled; I will report the result here the moment this step completes.

Implementation attempt 1 finished; I am verifying it now.

Running the project's own build, test, and lint commands against the change.

The change was implemented on the first attempt, with the project's own build, test, and lint commands all completing successfully. The next step is to commit the work, push the branch, and open a pull request for review.

I am delivering the change now.

Committing the verified change, pushing branch typosaurus/ticket-111, and opening a pull request.

The implementation for ticket-111 has been committed and pushed to branch typosaurus/ticket-111. A pull request has been opened at https://retoor.molodetz.nl/retoor/devplacepy/pulls/126.

This action was taken after the implementation passed the project's own checks.

I am now monitoring the pull request for review, merge, or further feedback.
