 # HOUSEBOT-005: Anonymous Feedback Flow
 
 ## Summary
+
 Allow members to submit anonymous household feedback to the bot via DM, then repost sanitized messages to a configured topic.
 
 ## Goals
+
 - Protect sender identity in group output.
 - Reduce conflict by neutralizing wording.
 - Prevent abuse with rate limits and blocklist controls.
 
 ## Non-goals
+
 - Anonymous reactions.
 - Admin identity reveal path.
 
 ## Scope
+
 - In: DM intake, sanitize/rewrite, posting, moderation guardrails.
 - Out: full moderation panel UI.
 
 ## Interfaces and Contracts
+
 - Bot command in DM: `/anon <message>` (or conversational prompt flow).
 - Use-case: `PostAnonymousMessage`.
 - Result includes posted message id and moderation outcome.
 
 ## Domain Rules
+
 - Sender identity is never included in reposted content.
 - Per-user cooldown and daily cap enforced.
 - Blocklisted phrases reject or request rewrite.
 
 ## Data Model Changes
+
 - `anonymous_messages`:
   - `household_id`
   - `submitted_by_member_id` (internal only)

 ## Security and Privacy
+
 - Internal sender reference is never exposed via group features.
 - PII minimization and retention policy documented.
 - Abuse logging without public reveal.
 
 ## Observability
+
 - Submission volume metrics.
 - Rejection/acceptance rate metrics.
 - Error logs for rewrite or post failures.
 
 ## Edge Cases and Failure Modes
+
 - Message too short/too long.
 - Spam bursts.
 - Telegram post failure after rewrite.
 
 ## Test Plan
+
 - Unit:
   - moderation and cooldown policy
   - anonymization invariants
