+Document role:
+This file is a small community prompt pack for an F1 grounding repair pattern.
+
+How to use this file:
+1. Read this page before using the prompts below.
+2. Use these prompts only after routing the case to F1 or a nearby grounding-first region.
+3. Treat this as a community prompt example, not as official atlas doctrine.

+# F1 Re-grounding Prompt Pack v1
+
+## Community prompt example
+
+This is a small community prompt pack for F1-style grounding repair.
+
+It is designed for cases where:
+
+- the answer looks fluent
+- the evidence anchor is wrong
+- the first repair move should be re-grounding
+
+---
+
+## When to use this pack
+
+Use this prompt pack when the case has already been routed to:
+
+- F1 Grounding & Evidence Integrity
+- or a nearby F1-first boundary region
+
+Do not use this pack as a substitute for routing.
+
+Route first.
+Prompt second.
+
+---
+
+## Prompt A
+
+### Re-grounding prompt
+
+```text
+You are debugging a grounding-first failure.
+
+Do not improve style first.
+Do not expand reasoning first.
+
+Your task is:
+
+1. identify the evidence source that should anchor the answer
+2. ignore semantically adjacent but unverified sources
+3. restate the answer using only the verified source
+4. state briefly why the original answer drifted
+
+Return:
+- verified anchor
+- corrected answer
+- short drift explanation
+````
+
+---
+
+## Prompt B
+
+### Anchor comparison prompt
+
+```text
+You are comparing two candidate evidence anchors.
+
+Your task is:
+
+1. identify which source is the valid anchor
+2. explain why the other source is misleading
+3. rewrite the answer using only the valid source
+
+Keep the output short and structured.
+Do not add unsupported inference.
+```
+
+---
+
+## Prompt C
+
+### Minimal route-first repair prompt
+
+```text
+This is an F1 grounding-first case.
+
+Do the first repair move only.
+
+Required steps:
+1. re-check the evidence anchor
+2. discard the wrong anchor
+3. produce a corrected answer from the verified anchor
+
+Do not attempt broader workflow redesign.
+Do not speculate beyond the verified source.
+```
+
+---
+
+## What this pack is trying to improve
+
+This pack is trying to improve:
+
+* anchor discipline
+* evidence fidelity
+* grounding-first repair behavior
+
+It is not trying to solve every downstream issue.
+
+---
+
+## Known limits
+
+This pack is weaker when:
+
+* no verified source exists
+* the case is really an F5 visibility problem first
+* the case is actually an F7 container problem disguised as a grounding issue
+
+---
+
+## One-line status
+
+**This is a small community prompt pack for route-first F1 re-grounding behavior.**
