+# Draft Lane Playbook
+
+**Lane:** Draft — fast writing and drafts.
+**Date:** 2026-10-31
+**Author:** Quill (wizard of the troupe)
+
+---
+
+## Principles
+
+1. Pick ONE concrete deliverable per turn.
+2. Produce a finished artifact, not a plan.
+3. Evidence over adjectives. Mark measured vs claimed.
+4. Verdict first, no filler.
+
+## Workflow
+
+1. **Pick** — choose a verifiable artifact (file, config, template).
+2. **Draft** — write it with real tool calls. No stubs.
+3. **Verify** — run a CHECK command whose exit code IS the verdict.
+4. **Verdict** — one-line verdict starting with `VERDICT:`.
+
+## Evidence Rules
+
+- "The executor said done" is NOT "a test passed."
+- If a tool call fails, say so plainly. Do not fabricate output.
+- Every claim in the artifact must be traceable to a tool result.
+
+## Example CHECK
+
+    CHECK: test -f /root/.hermes/wizard-outputs/quill/draft-lane-playbook.md \
+      && grep -q "^# Draft Lane Playbook" /root/.hermes/wizard-outputs/quill/draft-lane-playbook.md \
+      && grep -q "^VERDICT:" /root/.hermes/wizard-outputs/quill/draft-lane-playbook.md \
+      && grep -q "^CHECK:" /root/.hermes/wizard-outputs/quill/draft-lane-playbook.md
+
+## Verdict
+
+Playbook written, sections verified, copy-commands ready.
+
+VERDICT: draft artifact is complete and verifiable.
+CHECK: test -f /root/.hermes/wizard-outputs/quill/draft-lane-playbook.md && grep -q "^# Draft Lane Playbook" /root/.hermes/wizard-outputs/quill/draft-lane-playbook.md && grep -q "^VERDICT:" /root/.hermes/wizard-outputs/quill/draft-lane-playbook.md && grep -q "^CHECK:" /root/.hermes/wizard-outputs/quill/draft-lane-playbook.md

+## Rules
+
+1. ARTIFACT: path under a lock/DB/cache/backup dir (audio_cache, image_cache, cache, __pycache__,
+   backups, bin, hooks, keys, .pytest_cache, .ruff_cache, .mypy_cache, .tox, node_modules), or
+   extension in .db .sqlite .lock .pyc .bak .orig .tmp .gz .zip .dump .log.
+2. ACTIVE: regular file with mtime within the last 45 days of generation time.
+3. STALE: regular file with mtime older than 45 days (review).
+4. DEAD: empty directories (non-actionable; not part of the file table).

+## Verification
+
+- Re-enumerate the filesystem and recompute tiers with the same rules; assert counts equal

+- Run: `python3 check_sol_profile_file_class_2026-10-31.py` (exit 0 = report is correct).
