# Security Triage

Use when reviewing Quiet Core bot security advisories, drafts, or GHSA reports.

Goal: high-confidence maintainers' triage without over-closing real issues or shipping unnecessary regressions.

## Close Bar

Close only if one of these is true:

- duplicate of an existing advisory or fixed issue
- invalid against shipped behavior
- out of scope under `SECURITY.md`
- fixed before any affected release/tag

Do not close only because `main` is fixed. If latest shipped tag or npm release is affected, keep it open until released or published with the right status.

## Required Reads

Before answering:

1. Read `SECURITY.md`.
2. Read the GHSA body with `gh api /repos/liuda1999/Quiet-Core-bot/security-advisories/<GHSA>`.
3. Inspect the exact implicated code paths.
4. Verify shipped state:
   - `git tag --sort=-creatordate | head`
   - `npm view quiet-core-bot version --userconfig "$(mktemp)"`
   - `git tag --contains <fix-commit>`
   - if needed: `git show <tag>:path/to/file`
5. Search for canonical overlap:
   - existing published GHSAs
   - older fixed bugs
   - same trust-model class already covered in `SECURITY.md`

## Review Method

For each advisory, decide:

- `close`
- `keep open`
- `keep open but narrow`

Default to one advisory at a time when comments/closures are involved:

1. Review exactly one GHSA.
2. Print the GHSA URL first.
3. Summarize the decision and evidence for discussion.
4. Draft one maintainer-ready comment.
5. Copy only that one comment to the clipboard.
6. Stop and wait for Peter to post/discuss before moving to the next GHSA.

Do not batch multiple close comments unless Peter explicitly asks for a batch.

Check in this order:

1. Trust model
   - Is the prerequisite already inside trusted host/local/plugin/operator state?
   - Does `SECURITY.md` explicitly call this class out as out of scope or hardening-only?
2. Shipped behavior
   - Is the bug present in the latest shipped tag or npm release?
   - Was it fixed before release?
3. Exploit path
   - Does the report show a real boundary bypass, not just prompt injection, local same-user control, or helper-level semantics?
   - If data only moves between trusted workspace-memory files called out in `SECURITY.md`, do not treat "injection markers" alone as a security bug.
   - In that case, frame sanitization as optional hardening only if it preserves expected memory workflows.
4. Functional tradeoff
   - If a hardening change would reduce intended user functionality, call that out before proposing it.
   - Prefer fixes that preserve user workflows over deny-by-default regressions unless the boundary demands it.
5. Hardening follow-up
   - Even when the GHSA should close, ask whether a narrow hardening change would reduce footguns without changing the documented trust boundary.
   - Separate hardening from vulnerability status. Phrase it as "not required for GHSA closure, but worth considering".
   - Bring up hardening only if it is concrete, low-risk, and preserves intended maintainer/operator workflows.
   - If hardening would require a product/security model change, say that explicitly and do not imply it is a required fix for closure.

## Response Format

When preparing a maintainer-ready close reply:

1. Print the GHSA URL first.
2. Then draft a detailed response the maintainer can post.
3. Include:
   - exact reason for close
   - exact code refs
   - exact shipped tag / release facts
   - fix provenance or canonical duplicate GHSA when applicable
   - optional hardening note only if worthwhile and functionality-preserving

Keep tone firm, specific, non-defensive.

## Public Wording Hygiene

- Keep raw commit hashes, PR titles/numbers, and fix-mechanism summaries out of public advisory text. Use the patched release/version field only.
- Keep exact commit SHAs, PRs, and implementation notes in internal notes and verification files.
- For hardening/no-publish outcomes, do not add exploit-heavy details, "Fixed by" text, or a "Fix Commit(s)" section. Thank reporters, preserve credit, state the `SECURITY.md` boundary, and say clearly that the GHSA will close without publication.
- For published CVE/GHSA text, prefer `### Patched Versions` with the fixed release. Do not explain how the patch works unless Peter explicitly asks for that public detail.
- Keep GHSA ids out of changelog and release-note wording unless Peter explicitly asks.

## Discussion Mode

When Peter is manually posting GHSA comments, use this flow:

1. Show the URL.
2. Give a terse verdict (`close`, `keep open`, or `keep open but narrow`).
3. List the strongest evidence bullets.
4. State any optional hardening follow-up separately from the close reason.
5. Copy the proposed comment body with `pbcopy`.
6. End the reply after the one advisory. Do not continue to the next advisory until Peter says to continue.

If the GitHub API cannot post comments for private advisories, say so once and keep using clipboard/UI paste.

## Clipboard Step

After drafting the final post body for the current advisory, copy it:

```bash
pbcopy <<'EOF'
<final response>
EOF
```
