+# Branch Maintenance: Audit & Cleanup Plan
+
+> **Snapshot:** 2026-07-14 (UTC), measured against `origin/main` (`d171a154`).
+> **Regenerate before acting** — branch state drifts as PRs merge. This is a point-in-time report, not a live view.
+
+This document audits every branch (local and remote) and classifies it by how its work relates to `main`, then lists a concrete, staged deletion plan. It also scans for **dead/stale** branches by last-commit age.
+
+> [!IMPORTANT]
+> All measurements are against **`origin/main`**, **not** the local `main` branch. At snapshot time local `main` was **104 commits behind** `origin/main`; auditing against it would misclassify almost everything. Run `git fetch --prune origin` before regenerating.

+
+## TL;DR
+
+| Scope  | Linear-merged | Squash-merged | Unmerged | Total |
+|--------|--------------:|--------------:|---------:|------:|
+| Remote | 8 | 107 | 98 | 213 |
+| Local  | 1 | 13 | 6 | 20 |
+
+- **Safe to delete now:** all **Linear-merged** + **Squash-merged** branches (their work is already in `main`).
+- **Keep:** all **Unmerged** branches — they contain unique work not in `main`.
+- **Dead/stale flag:** **12** unmerged branches are >180 days old (abandoned), **25** are 90–180 days old. These need an **owner decision**, never auto-deletion.
+- **Status:** the delete plan below has since been **executed** (owner-run CLI) — see the [Execution Log](#execution-log). All merged branches (linear + squash) were removed; only unmerged branches and two protected `release/*` branches remain. The table above is the **audit-time snapshot**, retained as the record.
+
+---
+
+## Execution Log
+
+> **2026-07-14** — the delete plan in this document was executed via CLI (owner-run). Each branch was **re-verified fresh** against `origin/main` immediately before deletion (linear = `merge-base --is-ancestor`; squash = synthetic-commit + `git cherry` patch-id); every deleted SHA was recorded for recovery.
+
+**Deleted — 116 total (104 remote + 12 local):**
+
+| Tier | Deleted | Notes |
+|------|--------:|-------|
+| Linear-merged (remote) | 7 | ancestors of `main`; trivially recoverable from `main` history |
+| Squash-merged `ahead==1` (remote) | 51 | high-confidence single-commit squashes |
+| Squash-merged (local) | 12 | local counterparts of the above |
+| Squash-merged `ahead>1` (remote) | 44 | multi-commit; each patch-id-re-verified before deletion |
+| Trivial dead (remote) | 2 | `tairan/decoding_opt` (0 net diff), `tairan/CB` (1-line README) |
+
+A further ~12 already-merged branches had been deleted upstream between the snapshot and execution.
+
+**Held (deliberately not deleted):**
+
+- `release/v1.0.10.post3-glm5-stability`, `release/v1.0.10-glm5-cudagraph-clean` — merged, but match the protected `release/*` pattern.
+- `docs/glm51-enable-thinking-fix` (local) — checked out in a separate worktree, so `-D` was refused; its remote counterpart was deleted.
+
+**Recovery:** deleted tips are restorable with `git push origin <sha>:refs/heads/<name>` (SHAs saved in the operator's recovery manifests; server reflog retains them ~90 days).
+
+**State after execution** (vs `origin/main` `d171a154`): **100 remote branches remain — 2 merged (both protected `release/*`) and 98 unmerged** (24 with open PRs). Unmerged/no-PR by age: **10 dead** (≥180d), **25 stale** (90–179d), **39 active** (<90d). No unmerged, dead, or stale branch was deleted.
+
+---
+
+## Scope & Method
+
+Each branch tip is compared to `origin/main` and placed in exactly one class:
+
+| Class | Definition | Detection | Safe to delete? |
+|-------|------------|-----------|-----------------|
+| **Linear-merged** | Branch tip **is an ancestor** of `origin/main` — every commit is present in `main`'s history, unchanged. Full linear history preserved. | `git merge-base --is-ancestor <branch> origin/main` | **Yes** — `git branch -d` accepts it. |
+| **Squash-merged** | Branch's **net diff** is already in `main`, but as a rewritten (squashed/rebased) commit with a different SHA. Individual commits are **not** linearly in `main`. | Synthetic full-tree commit on the merge-base, then `git cherry origin/main <synthetic>` patch-id match (equiv. to `git-delete-merged-branches --effort=3`). | **Yes**, but `git branch -d` **refuses** it — `-D` required. |
+| **Unmerged** | Has commits whose patch is **not** in `main`. | Neither of the above. | **No** — deleting loses work. |
+
+**Dead/stale** is an orthogonal, age-based axis applied to **unmerged** branches (committer-date of the tip):
+- **Dead** — no commits in **>180 days** (abandoned).
+- **Stale** — no commits in **90–180 days**. (90 days = GitHub's own "Stale branches" UI threshold.)
+
+---
+
+## Policy Context
+
+- **`PR_MERGE_POLICY.md` § 4 (Commit & branch hygiene)** already mandates branch discipline: work on `<handle>/<short-description>` branches, no direct commits to `main`, and — most relevant here — **"Delete the PR branch once merged."** This document **operationalizes** that rule for the accumulated backlog of branches that were merged but never deleted; it does not introduce a new policy.
+- **`CONTRIBUTING.md` § Merge Policy** governs *who* merges (owner-only merge button, ≥1 approving review, green CI; direct pushes to `main` reserved for the owner).
+- Neither doc pins a merge *method*, but the squash-merge counts below reflect a de-facto **squash-merge** workflow (even `chore/contributing-merge-policy` and `chore/cleanup-for-migration` are squash-merged into `main`).
+- There is **no stale-branch automation** in `.github/workflows/` today, so this cleanup is manual. A companion PR proposes a report-only stale-branch workflow to enforce §4's "delete once merged" going forward.
+
+---
+## 1. Linear-merged — full linear history (SAFEST to delete)
+
+Tip is a true ancestor of `origin/main`; every commit is already in `main`. `git branch -d` accepts these.
+
+**Local (1):** `main` — an ancestor of `origin/main` but **do not delete**; it is your default branch, just stale (104 behind). Fast-forward it instead: `git fetch origin && git branch -f main origin/main` (when not checked out).
+
+**Remote (8):**
+- `ci/sglang-release-test`
+- `release/v1.0.10.post3-glm5-stability`
+- `tairan/adapt_Pynccl_Comm`
+- `tairan/cold_start_opt`
+- `tairan/fix_posix_shm`
+- `tairan/fix_stateless_comm_init`
+- `tairan/full-dsa-cuda-graph-prod`
+- `tairan/urgent_fix`
+
+---
+
+## 2. Squash-merged — work in `main`, history rewritten (SAFE, but not linear)
+
+The branch's net diff is already in `main` under a different (squashed) SHA. Safe to delete, but `git branch -d` will **refuse** them (it only sees ancestor reachability), so `-D` is required. Split by confidence:
+
+### 2a. High confidence — single-commit squash (`ahead == 1`)
+
+One original commit, cleanly squashed into `main`. Deletion is unambiguous.

+### 2b. Review-first — multi-commit squash (`ahead > 1`)
+
+Detected as squash-merged because the **whole branch's net diff** matches `main`, but each carries multiple commits. The patch-id signal is reliable, yet the commit count warrants a quick human glance before bulk deletion (guards against a branch that was squash-merged and then had unrelated commits reverted to a net-equal state).

+## Delete Plan
+
+> Execute top-to-bottom. Each tier is safe on its own; stop at any point. **Nothing here runs automatically** — copy/paste after review. Remote deletions are owner-gated per `CONTRIBUTING.md`.
+
+### Step 0 — Sync (always first)
+
+```bash
+git fetch --prune origin      # drop remote-tracking refs for already-deleted branches
+```
+
+### Step 1 — Local branches (this machine)
+
+```bash
+# Linear-merged: -d refuses if not truly merged (safety kept on purpose)
+git branch -d main            # SKIP — keep default branch; fast-forward instead:
+# git fetch origin && git branch -f main origin/main   # (only when 'main' not checked out)
+
+# Squash-merged locals (-D required; -d would refuse):

+### Step 5 — Unmerged dead/stale (DO NOT auto-delete)
+
+These hold unique work. Ping the owner (see §3 ownership) and only delete after explicit confirmation. There is no safe bulk command for this tier by design.

+
+## Safety & Recovery
+
+- **`git branch -d` vs `-D`:** `-d` refuses to delete a branch that isn't an ancestor of its upstream — keep using it for linear-merged branches as a built-in guard. `-D` (force) is only needed for squash-merged branches, where `-d` cannot see through the rewritten commit.
+- **`--force-with-lease`:** if you script remote deletion via a tool that pushes, prefer `--force-with-lease` over `--force` so a colleague's newer commit on the same ref is never silently discarded.
+- **Recovery window:** a deleted branch tip is recoverable from the reflog for **~90 days** (`gc.reflogExpire` default; 30 days for unreachable objects). Recover with `git reflog --all | grep <branch>` then `git branch <branch> <sha>`. Beyond that, `git fsck --lost-found` is a last resort until the next `git gc`.
+- **Protected/open-PR branches:** GitHub refuses to delete branches tied to open PRs, and branch-protection rules/rulesets can block deletion server-side. Enable **Settings → Automatically delete head branches** to auto-prune PR-merged branches going forward.
