+# Product / component verification
+
+Bugs are frequently filed against the wrong `Product :: Component`. Part of triage is
+confirming the bug is filed where it belongs and, when it isn't, proposing the correct
+`Product :: Component` so it reaches the right team.
+
+Do this **after** you have localized the affected code (you need concrete file paths to
+verify ownership), and record the result in the `component_assessment` structured-output
+object.
+
+## How to verify
+
+1. **Find the ownership map.** The Firefox source tree ships a module-ownership file,
+   `mots.yaml` (the maintainer/module metadata; commonly at the repo root or under
+   `source/`). Glob for it (`**/mots.yaml`) and Read it. Each module lists path globs it
+   owns (e.g. an `includes:` list) and its Bugzilla product/component (e.g. under a
+   `meta`/`components` mapping — field names may vary slightly, read the file to see the
+   shape).
+2. **Match your localized paths to a module.** Take the file path(s) you identified as
+   the root cause and find the module whose path globs own them. That module's Bugzilla
+   product/component is the _expected_ component for a bug in that code. Use Searchfox to
+   confirm ownership when a path spans directories or the mapping is ambiguous.
+3. **Compare with the bug.** Compare the expected `Product :: Component` against the
+   bug's current values.
+
+## What to record
+
+- If the current component matches, set `component_assessment.correct` to `true`, leave
+  the suggestions null, and give a one-line rationale.
+- If it clearly belongs elsewhere, set `correct` to `false`, put the corrected values in
+  `suggested_product` / `suggested_component`, and in the rationale cite **both** the
+  `mots.yaml` module that owns the path **and** the path evidence.
+
+## Confidence and field changes
+
+- **High** — the localized path is unambiguously owned by one module and the mismatch is
+  clear. Only then may you record a `bugzilla_update_bug` proposing the corrected
+  `product` / `component` (see the system prompt's recording rules). Cite the mots.yaml
+  module and path in the `reasoning`.
+- **Medium / low** — the code area is uncertain or the path is owned by multiple modules.
+  Report the assessment (and your best suggestion) in the comment and structured output,
+  but do **not** record a field change.
+
+## Interaction with scoping
+
+A wrong-component finding can mean the bug is out of scope for a _frontend fix_ — e.g.
+the code you localized is Core (layout, DOM, graphics), not a Firefox frontend
+component. In that case, still record the component assessment and the proposed
+correction, but do not invent a frontend fix plan: set `actionable` per the scoping
+rules and let the comment focus on the re-triage.

+# Severity assessment
+
+Assess an appropriate Mozilla severity for the bug and record it in the
+`severity_assessment` structured-output object. Base the judgment on **user impact and
+reach** as evidenced by the bug report and the code you investigated — how badly the
+user is affected, how many users hit it, and whether a workaround exists.
+
+## Severity definitions
+
+- **S1 — catastrophic.** Crash, hang, data loss, security issue, or a bug that blocks
+  major functionality with **no workaround**. Affects a large number of users.
+- **S2 — serious.** Major functionality is broken or a severe UX problem, and the
+  workaround (if any) is painful or non-obvious. Affects many users.
+- **S3 — normal.** Blocks non-critical functionality, or a reasonable workaround exists.
+  **This is the default for most frontend papercuts.**
+- **S4 — minor / trivial.** Cosmetic issues, small polish, or edge cases with negligible
+  impact.
+
+## Guidance
+
+- Frontend UI/UX papercuts are usually **S3** (or **S4** when purely cosmetic). Reserve
+  **S1 / S2** for genuine breakage: crashes, data/state loss, or a broken core workflow
+  with no easy workaround.
+- Weigh: is it functional vs cosmetic? Is there a workaround? How frequently and how
+  broadly is it hit (mainline path vs rare configuration)?
+- Do **not downgrade** an existing higher severity unless you have strong evidence the
+  impact is lower than currently recorded.
+
+## Confidence and field changes
+
+- **High** — impact is clear-cut (clearly cosmetic, or clearly a crash/data-loss). Only
+  then may you record a `bugzilla_update_bug` proposing the `severity` (see the system
+  prompt's recording rules), with a `reasoning` citing the impact evidence. Prefer not to
+  propose a change when the bug already carries a reasonable severity.
+- **Medium / low** — suggest a severity in the comment and structured output, but do
+  **not** record a field change.
