chore(0010): remove stale .gitignore entry for rendered policies

[fullsend-ai-retro]

What happened

PR #42 removed the policy rendering pipeline from experiment 0010 (no more HOST_IP resolution, no more sed template substitution, no more rendered policy files). However, the .gitignore at 0010-host-side-api-server/.gitignore still contains policies/rendered-*.yaml on line 1. The review agent flagged this as a low-severity finding in its approval comment: 'Line 1 (policies/rendered-*.yaml) is now stale — rendered policies are no longer generated after this change. Harmless but could be cleaned up.' The finding was not addressed before merge.

What could go better

The review agent correctly identified this vestigial entry but the author chose not to address it (likely because it was harmless and the primary change was already validated). This is a minor cleanliness issue. Confidence: high — verified by reading the current .gitignore file.

Proposed change

Remove the stale policies/rendered-*.yaml line from 0010-host-side-api-server/.gitignore. This is a one-line deletion with no functional impact.

Validation criteria

The .gitignore file in 0010-host-side-api-server/ no longer references policies/rendered-*.yaml.

Triage Summary

Severity: low · Category: chore/cleanup

Problem

The .gitignore at 0010-host-side-api-server/.gitignore still contains a stale entry policies/rendered-*.yaml on line 1. This entry was relevant when the experiment had a policy rendering pipeline, but that pipeline was removed in PR #42. The review agent flagged this during review; it was not addressed before merge.

Confirmed state

The file currently contains:

policies/rendered-*.yaml   ← stale, should be removed
bin/
__pycache__/
*.pyc

Recommended fix

Delete line 1 (policies/rendered-*.yaml) from the file. No other changes needed.

Proposed test

# After fix, verify the stale entry is gone:
assert 'rendered' not in open('0010-host-side-api-server/.gitignore').read()
# File should have exactly 3 remaining lines: bin/, __pycache__/, *.pyc

This is a one-line deletion with zero functional impact — safe to merge with minimal review.

Labels: This is a low-severity cleanup chore. Marking as 'good first issue' since it is a trivial one-line change, and adding 'triaged' to reflect completed triage.
