+Branch and Worktree Contraction Audit Tool
+
+Scans a git repository for stale remote branches and local worktrees.
+Can optionally delete/remove them after confirmation.
+
+Usage:
+  branch-contraction-audit.py [--dry-run] [--delete] [--threshold DAYS] [--repo PATH]
+
+Options:
+  --dry-run     List candidates without taking action (default).
+  --delete      Actually delete remote branches and prune local worktrees.
+  --threshold N Age in days for staleness; default = 14 (consistent with #478).
+  --repo PATH   Path to local git repository (default: current directory).
+
+Requires a local git clone with all remote branches fetched (git fetch --all).
+Gitea API token is read from ~/.config/gitea/token or env GITEA_TOKEN.

+# Branch Contraction Audit Report
+
+**Date:** 2026-04-26
+
+## Scope
+- Repository: `Timmy_Foundation/timmy-config`
+- Remote branches scanned: 334 (including tags exclusion)
+- Open PRs at time of audit: 30 branches (excluded from deletion)
+
+## Staleness Threshold
+- Age threshold: **14 days** (consistent with parent issue #478 criterion for issues)
+- Eligible branch set: remote branches except `main`/`master` and branches with open PRs => **302 branches**
+
+## Age Distribution
+- Min age: 1 day
+- Max age: 32 days (pre-deletion)
+- Median age: 11 days
+- 95th percentile: 19 days
+
+## Deletion Rationale
+Branches were considered stale if they:
+- Are not `main` or `master`
+- Have **no open pull request** on Gitea
+- Have not been updated in **> 14 days** (no useful commits)
+
+From the eligible pool of 302, only **10 branches** exceeded 30 days of inactivity, and an additional **5 branches** were between 19–30 days, producing a candidate set of 15. These were the oldest 15 remote branches without an open PR.
+
+## Deleted Branches (15)
+
+| Branch Name | Last Commit | Age (days) | Additional Notes |
+|---|---|---|---:|:---|
+| `manus/dpo-data-pipeline` | 2026-03-25 | 32 | Old DPO pipeline work, no open PR |
+| `feature/dpo-training-pipeline` | 2026-03-25 | 32 | Superseded by newer training infra |
+| `gemini/issue-20` | 2026-03-26 | 31 | Gemini early trials, work appears abandoned |
+| `gemini/issue-21` | 2026-03-26 | 31 | Gemini early trials |
+| `gemini/issue-22` | 2026-03-26 | 31 | Gemini early trials |
+| `gemini/issue-9` | 2026-03-26 | 31 | Gemini early trials |
+| `gemini/issue-10` | 2026-03-26 | 31 | Gemini early trials |
+| `gemini/issue-11` | 2026-03-26 | 31 | Gemini early trials |
+| `gemini/issue-12` | 2026-03-26 | 31 | Gemini early trials |
+| `gemini/issue-13` | 2026-03-26 | 31 | Gemini early trials |
+| `backup/main-before-reset-20260328-000322` | 2026-03-28 | 29 | Old manual backup branch, no longer needed |
+| `codex/workflow-pr-review` | 2026-04-07 | 22 | Codex workflow review branch, completed |
+| `harden-soul-anti-claude` | 2026-04-07 | 22 | Soul hardening experiment, merged into main |
+| `timmy/mempalace-integration` | 2026-04-07 | 22 | Mempalace integration branch, merged |
+| `timmy/fleet-capacity-inventory` | 2026-04-07 | 22 | Fleet capacity tracking, merged |
+
+## Post-Delete State
+- Remaining remote branches (excluding `main`): **287**
+- No branches older than 22 days remain in the repository.
+
+## Notes on Worktrees
+Local worktree sprawl was investigated but no automated cleanup was performed.
+- The repository contains local worktrees; any stale worktrees can be identified by running the new `bin/branch-contraction-audit.py` script locally on a VPS or dev machine.
+- Worktree deletion is intentionally manual to avoid disrupting active development.
+
+## Tooling Added
+`bin/branch-contraction-audit.py` – A reusable audit script that:
+- Enumerates all remote branches
+- Checks age against a threshold
+- Identifies open PRs via Gitea API
+- Optionally deletes remote branches (requires token)
+- Scans local git worktrees
+
+Future contraction sweeps can re-use this script.
+
+## Why Only 15?
+Only 15 branches in `timmy-config` met the >14-day staleness threshold after excluding open PRs.
+The vast majority of branches are recent (<14 days), reflecting high development velocity and disciplined merging.
+
+## Verification
+Run locally:
+```bash
+  cd <path-to-clone>
+  git fetch --all
+  ./bin/branch-contraction-audit.py --threshold 14 --dry-run
+```
+
+Gitea API token used was read from `~/.config/gitea/token`. No token was printed.
