CaptureRepository#update — InnoDB row-lock timeout

Now I have the cluster details. Let me invoke the RCA skill.

This is a latency cluster for `Api::V1::Admin::CapturesController#update` taking ~50 seconds in EU r

I have comprehensive evidence from both Datadog logs and source code. The root cause is clear: MySQL

Now I have all the evidence needed. Let me write the RCA report.

Now let me update the cluster frontmatter — but the user explicitly said NOT to modify the cluster f

RCA complete. The report is at `content/docs/incidents/be196c4b-4151-49c7-acac-99be79e4e5ed/rca.mdx`

I'll start by checking if a state file already exists and reading the necessary inputs.

No existing state file. Let me now read the templates and check for memory episodes.

I found a highly relevant memory entry: "Nested state machine lock timeout" pattern and the "Fix Sco

Excellent. I have critical memory context. The key lesson from episode 78dd34b4 is:

Now I have all the context needed. Let me proceed with Phase 1 — creating the state file.

Phase 1 done. Now Phase 2 — I need to explore the affected code in the tesla repo to design the plan

Now let me check if there are existing retry patterns in the tesla codebase that I can follow.

I can see there's a retry pattern in the codebase already (e.g., `workspace_permission.rb`, `elastic

Now I have a clear picture. The `after_transition from: any, to: %i[done skipped]` callback at line

No existing `Retryable` concern for lock retries. Let me look at how `workspace_permission.rb` does

Good. The codebase uses simple `rescue ... retry` patterns. Now I have enough context to write the p

Now update state.mdx for Phase 2 completion.

Now Phase 3 — Create Jira Issue.

Now let me create the Jira issue:

Jira issue created: **TSLA-13025**. Now update the description with the full RCA report.

The sed command didn't strip correctly. Let me use a simpler approach:

Good, content starts correctly. Now update the Jira description with full RCA:

Now add the RCA web link and clean up:

Now update state.mdx with Jira info:

Phase 3 done. Now Phase 4 — Prepare Worktree.

Now copy `.env` to the worktree per repo-mapping setup instructions:

Update state.mdx:

Phase 4 done. Now Phase 5 — Implement the fix.

Now validate syntax:

Syntax is valid. Now commit:

Phase 5 done. Update state.mdx:

Now Phase 6 — Validate with blind subagent. Let me collect the git diff and prepare the validation.

Now let me read the validator agent prompt and validation template:

Now launch the validation subagent:

Validation passed — **APPROVED**. Let me verify the file was written and update state:

The validator raised a good point about the `private` keyword possibly affecting `upload_meshes` and

Let me check the original file to see what visibility `upload_meshes` and `analyze_panos` had:

Indeed — `upload_meshes` and `analyze_panos` were **public** methods in the original file (before th

Now I need to add the private method after the `protected` section. Let me read the full file to see

I see the file ends with `class << self` ... `end` then `end` (class end). Let me find where `protec

The structure is: public methods → `protected` at line 52 → protected methods → `class << self`. I'l

Now validate syntax again and re-commit:

**Syntax OK**. Now amend the commit with the fix:

Good. Now let me verify the final diff:

The `private` keyword is now placed after line 174 (after `_search` which is a protected method), an

Phase 6 done. Now Phase 7 — Create PR.

Now create the PR:

The `DefaultCollection` pattern didn't match. Let me check the remote URL directly:

Project is `tesla`, repo is `tesla`. The URL format is `https://dev.azure.com/cupix/{project}/_git/{

PR created successfully! PR #87923. Now update state and cluster file:

Now update the cluster file `resolution`:

Phase 7 done. Now Phase 8 — Reflection.

Now update the service memory with this new pattern:

Now update state.mdx Reflection row:

All phases complete. Here's the summary:

State file already exists. Let me check the current state and read the templates/state.md.

The state shows `phase: completed` — a previous run already finished all phases. However, looking at

Let me read the relevant memory files and the previous episode for this cluster.

**Memory context found:** 2 relevant episodes from the `mysql-lock-timeout` category:

No templates directory exists. I'll create state/plan/etc from the existing format. Let me check wha

There's already a worktree from the previous run. Let me check its state.

The worktree already has the previous fix (retry logic) committed on `feature/TSLA-13025`. Since the

Now I have a complete picture of the code. Let me also check how `after_commit` is used elsewhere in

The `saved_change_to_state?` pattern already exists in the codebase. Now let me also check what the

I can see `saved_change_to_editor_id?` and `after_commit` is already used in the Editing model (line

Now let me write the plan.

Now update state.mdx for Plan done and proceed to Jira.

Now Phase 3: Create Jira issue.

Jira issue created: **TSLA-13030**. Now let me update the description with full RCA and add a link.

Now update state.mdx with Jira info.

Phase 4: Prepare worktree.

Good. Now set up the worktree (copy .env if needed per repo-mapping).

Update state.mdx:

Phase 5: Implement. Let me read the file from the worktree to make edits there.

Now I'll implement the changes. The strategy is:

Now I'll implement the changes. The plan is to:

Now I need to add the `after_commit` callbacks in the `included do` block, after the `state_machine`

I see line 177 is the `end` of the `state_machine` block. I need to add `after_commit` callbacks bet

Now I need to add the private methods for these callbacks. Let me read the current end of the file t

Now I'll add the callback methods before the closing `end` of the `included` block (which is at line

The structure is: all methods defined after the state_machine block are inside `included do`. The `e

Let me verify the final file looks correct:

I notice a potential issue: `prepare_escalated_state`, `sync_review_completion`, `start_sitetrack`,

Update state.mdx:

Phase 6: Validate with blind subagent. Let me get the diff and prepare the validation.

Now let me read the validator agent template and launch the validation subagent.

Now let me check if there's a validation template:

Now I have everything needed for the validator subagent. Let me launch it.

The validator approved with verdict APPROVED. Let me read the validation file and move it to the cor

Good. Let me copy the validation file to the correct location and clean up.

Now update state.mdx for validation done.

Phase 7: Create PR. Push branch and create Azure DevOps PR.

The regex didn't match because the URL format doesn't have `/DefaultCollection/`. Let me extract the

Good. Now create the PR.

PR created successfully: **PR #87931**. Now update state and cluster files.

Now update the cluster file resolution:

Phase 8: Reflection. Update the episode and service memory, then create summary.

Update the episode with the new fix (this is a follow-up fix for the same cluster):

Now update service memory:

Now create the summary.

Update state.mdx Reflection row:

All phases complete. Here's the summary:

The state.mdx shows this cluster was already completed with a previous fix ("after_transition → afte

I have all the information needed. Now let me write the plan.

The file doesn't exist yet (it's a new file for this attempt). Let me check:

Now I'll overwrite it with the new plan for the async Worker approach.

Now update state.mdx to mark Plan as done.

## Phase 3: Create Jira Issue

Now let me create the Jira issue. I'll prepare the description:

Jira issue created: **TSLA-13049**. Now update the description with the full RCA and add the web lin
