## Submitter notes for this review

The submitter has attached the following context for this review — it may include excerpts of a spec or PRD, the intended behaviour change, or judgment guidance for borderline cases. Read it before the diff and let it shape what you flag (or don't flag), but it does not relax the review checklist below.

## Context from the prior review

You have already reviewed this PR once. The comments raised last round and the author's follow-up replies are below. Treat this as context, not a checklist:

- Focus on two things: (1) whether the must / should items from last round were actually fixed, and (2) hunks in the diff marked `← NEW since` — those are the changes that appeared after the previous review.
- For items where the author has given a **reasonable explanation**, **do not raise the same point verbatim again**. If the explanation does not hold up, you may re-raise it, but the new finding's body must explicitly say "I read your reply to prior #<X>; the part that does not hold up is …".
- Already-published comments are listed below. If you find the same issue this round, skip it; new issues from a different angle are fine to raise.
  {{#FORCE_PUSHED}}
- ⚠️ Note: the PR has been force-pushed since the last review, and the prior commit `{{LAST_REVIEWED_SHA}}` is no longer in the current history. Treat the entire diff as new — do not assume "previously reviewed regions are unchanged".
  {{/FORCE_PUSHED}}
  {{^FORCE_PUSHED}}
- The previously reviewed commit was `{{LAST_REVIEWED_SHA}}`.

## Source at PR head

A working tree of this PR is checked out at:

`{{SOURCE_PATH}}` (commit `{{HEAD_SHA}}`)

**Files there reflect the post-merge state of this PR**, so reading them tells you exactly what the diff produces. Use this to expand context beyond the diff hunks — inspect callers of a changed function, check whether a removed export still has consumers, walk into adjacent modules. You may run read-only shell / git commands inside it. Do not modify any files; the diff below remains the canonical source of truth for what changed in this PR.

{{/SOURCE}}
{{#SOURCE:snapshot}}

## Source at PR head (partial)

A snapshot of files this PR touches, fetched at commit `{{HEAD_SHA}}`, is available at:

`{{SOURCE_PATH}}`

**Only the files the diff touches are present** — callers, sibling modules, and unmodified files are not. The snapshot reflects the post-merge state of those files; reading them tells you what the diff produces. For broader context, ask the user to pin a local clone of this repository when starting the review. Treat the snapshot as read-only.

{{/SOURCE}}

## Diff

Each body line below is prefixed with a `<NEW_LINE> | ` gutter where `<NEW_LINE>` is the line's number in the new file. Use that gutter as the source of `line` and `startLine` for findings — do NOT count offsets from `@@` headers. Removed (`-`) lines have a blank gutter because they don't exist in the new file and cannot be targeted by inline comments.

Some non-reviewable files (dependency lockfiles, minified bundles, snapshots) have already been removed from the diff below. If you still see a file that is clearly generated, vendored, or machine-produced (large auto-generated client code, committed build output, etc.), you may skip reviewing it and need not report findings on it.

{{DIFF}}

## Review checklist

Apply the rules below against the diff. Skip any rule whose preconditions don't appear in the diff. The rules section may enumerate allowed `category` strings — if it does, every finding's `category` must match one of those strings exactly; otherwise pick a short, descriptive free-form `category` label yourself.

{{RULES}}

## Severity rubric

- 🔴 **must** — blocks merge: bugs that will hit production, security issues, type-safety escape hatches, broken contracts.
- 🟡 **should** — serious enough that a reviewer would normally request changes: design smells, missing error handling, performance traps, naming that will mislead.
- 🔵 **nit** — minor polish: small naming preferences, comment fixes, optional refactors. Never blocks.

## Output

This review produces two files. Use whatever file-write capability your runtime provides (the Write tool, a shell write, etc.); do NOT print either report to stdout.

### Findings file

You MUST write a JSON array of findings to the file at: {{FINDINGS_PATH}}.

Each finding must conform to this schema:
{{SCHEMA}}

Rules:

- Do NOT print the report to stdout — write only to the findings file.
- IDs are "R1", "R2", ... numbered globally across all findings, in the order you write them.
- Use `file: null` and `line: null` for cross-file or PR-level findings; those will be aggregated into the review body.
- For file-anchored findings, `line` MUST refer to a line that appears in the diff above (a changed line or a line within a hunk's context window). If a finding genuinely refers to an untouched line, set `file: null` and `line: null` so it goes into the review body.
- `severity` ∈ `"must"` | `"should"` | `"nit"`.
- `title` is a one-line summary; `body` is markdown with the concrete problem.
- If you find no issues, write an empty array `[]` — do not invent praise findings.

### How to use `suggestion`

GitHub renders the `suggestion` field as a fenced "suggestion" code block. When a maintainer clicks "Commit suggestion", GitHub replaces the targeted lines `[startLine..line]` **verbatim** with the suggestion text. So `suggestion` is a literal patch, not an illustrative snippet.

**Default: provide `suggestion` whenever the fix is a contiguous edit inside one file.** Omitting `suggestion` and putting code in `body` loses the one-click apply — only fall back to body-only when the fix genuinely can't fit a single contiguous drop-in (multi-file, requires changes outside any current hunk, or depends on context the diff doesn't expose). When in doubt, try the inline form.

**Targeting (`line` and `startLine`)**

- `line` is the **last** line being replaced. Must appear in the diff above.
- For a multi-line replacement, set `startLine` to the **first** line being replaced. `startLine` must also appear in the diff, and every line in `[startLine..line]` must be inside the diff.
- For a single-line replacement, omit `startLine`.
- The number of lines inside `suggestion` does NOT have to equal `line - startLine + 1` — GitHub allows the replacement to be longer or shorter than the original. What matters is that `[startLine..line]` covers the original block you intend to replace.
- ⚠️ If you write a multi-line `suggestion` but anchor only at `line` (no `startLine`), GitHub will replace just that one line and inflate the file. Always set `startLine` for multi-line cases.

**Content requirements**

- The text of `suggestion` is the exact code that should occupy `[startLine..line]` after the patch. Match the surrounding indentation precisely.
- No `// ...`, no `/* ... */`, no ellipsis, no `// path/to/file.ts` headers, no pseudo-code, no prose. The block must compile / parse in place.
- A single `suggestion` cannot span multiple files.

**Worked examples**

- _Single-line tweak._ Original line 43 reads `      clientId: 'podcast-service',`. To rename: `line: 43`, no `startLine`, `suggestion`:
  ```
        clientId: 'transcode-service',
  ```
- _Multi-line replacement._ Original lines 267-269 form an `if (eid) { this.eventTracker.trackStarted(eid) }` block. To gate it on first attempt: `startLine: 267`, `line: 269`, `suggestion`:
  ```
      if (eid && job.attemptsMade === 0) {
        this.eventTracker.trackStarted(eid)
      }
  ```
  Do NOT use `line: 269` alone — that would replace just the closing `}` and leave the original `if`/body in place above.

### Review summary file

You MUST also write a single JSON object to the file at: {{SUMMARY_PATH}}. This summary powers a human-facing overview of the review — it is separate from the findings.

It must conform to this schema:
{{SUMMARY_SCHEMA}}

Guidance:

- `overview` — a short markdown description (a few sentences or a handful of bullets) of what this change set actually does: the main changes, grouped by intent. Describe the change itself, not your findings.
- `manualReview` — the files or areas where a human should review carefully on their own, each with a concrete `reason`. Use it for what automated review cannot fully verify: judgment calls, security-sensitive surfaces, behaviour that depends on context outside the diff, or anything you were genuinely uncertain about. Set `file` to the repo-relative path, or `null` for a change-set-wide note. An empty array is correct when nothing warrants special human attention — do not pad it.
- Write the summary even when the findings array is empty.
