[WIP] Continue implementing improvements to script execution lifecycle

[Copilot]

Thanks for asking me to work on this. I will get started on it and keep this PR's description up to date as I form a plan and make progress.

Original prompt

Continue work on the existing pull request branch for PR #6 in repository danielsobrado/P2P-Market-Data and implement the plan already described in that PR with real source code changes.

PR URL: #6
Head branch: copilot/add-second-half-fixes
Base branch: main

The PR already contains a detailed implementation plan and currently shows real changed files. Continue and complete the implementation on that PR branch rather than opening a planning-only PR.

Required focus areas

A. Script execution lifecycle

• Eliminate double-Wait() race in script shutdown.
• Ensure StopScript performs graceful stop -> timeout -> force kill without hanging.
• Make Python resolution fail early and clearly.
• Improve structured output/error handling in script execution.
• Ensure dependency validation temp files are created outside the live script directory.
• Add/update tests for stop behavior, missing Python, temp-file handling, and output/error handling.

B. P2P correctness

• Fix connection count/accounting drift in peer connection handling.
• Make validator selection return an error when all records are invalid.
• Ensure signed message payload covers the integrity-sensitive fields consistently.
• Address practical thread-safety/config-validation issues in host lifecycle code where applicable.
• Add/update targeted tests.

C. Migration/tooling safety

• Fix cleanup bug in scripts/proto_to_sql.py for partially initialized state.
• Improve SQL generation safety via identifier validation/quoting.

D. Frontend UX consistency

• Ensure script action handlers refresh state after successful actions.
• Ensure fetched script content is surfaced instead of silently discarded.
• Improve connection status presentation/update consistency reasonably within scope.

Acceptance criteria

• Keep working on PR Fix script lifecycle, P2P accounting, migration safety, and frontend state refresh #6 / branch copilot/add-second-half-fixes.
• Make real code changes, not just plan text.
• Add or update tests where practical.
• Leave the PR in a reviewable state with implementation matching the plan.

The following is the prior conversation context from the user's chat exploration (may be truncated):

Assistant: The pull request for hardening script execution and fixing remaining runtime, P2P, migration, and frontend issues is being created now.
You can track its status here: PR Link.

Once both PRs are ready, please review and merge them to address the full scope of recommended fixes. Let me know if there’s anything else you’d like to adjust!

User: Anything pending now?

Assistant: Yes — a few things are still pending.

Current status

• PR 1: requested earlier, but I do not have a confirmed PR URL from the tool in this chat.
• PR 2: you shared https://github.com/danielsobrado/P2P-Market-Data/pull/3, so that one appears to exist.

What’s still pending

1. PR 1 confirmation

   • I still need the actual PR link/number for the first PR, or confirmation that it was created successfully.

2. Review/merge

   • Even if both PRs exist, the fixes are not fully “done” until they’re reviewed and merged.

3. Validation after merge

   • Recommended final checks:
     • run Go tests
     • run frontend build/tests if available
     • smoke test Wails startup
     • smoke test script execution/start-stop flow
     • smoke test peer connection behavior

Short answer

• Implementation requests: no additional PR requests are pending from my side.
• Operationally: yes, still pending:
  • confirm PR 1 exists
  • merge PR 1 and PR 2
  • validate the merged result

If you want, I can help you figure out whether PR 1 already exists from the repo state.

User: Do that

Assistant: I couldn’t confirm any open PR details from the repo with the data returned just now.

What I can confirm

• You provided this PR URL:
  • https://github.com/danielsobrado/P2P-Market-Data/pull/3

What I could not confirm

• Whether PR 1 exists
• Whether PR 3 is open/merged/closed
• The titles/states of current PRs from the repository API response I received

So what’s pending right now

Yes, there is still one important pending item:

• Confirm PR 1 exists and get its URL/number

And operationally, still pending:

• review/merge the PRs
• validate after merge

Fastest next step

If you open the repo PR list and send me:

• the link for PR 1, or
• a screenshot / list of open PRs,

I can immediately tell you exactly what remains pending.

Right now, the best status summary is:

• PR 2 / PR 3 link provided by you: likely exists
• PR 1: unconfirmed
• All fixes fully complete: not yet, until both PRs are confirmed and merged

User: Can you merge them?

Assistant: I can’t confirm the merges from here right now.

What I know:

• You’ve now provided PRs:
  • [WIP] Improve startup/config/error handling stability #3
  • [WIP] Improve runtime safety and user experience in P2P market data #4

What’s pending:

• whether those PRs were actually merged successfully
• whether there were ...
