housekeeping: prune merged branches (16 local + 5 remote); keep docs/epic-b-macos-windows-detection

[gnanirahulnutakki]

Context / Problem

A pile of already-merged (or duplicate) branches lingers locally and on the remote, cluttering the branch list and making it hard to see active work. These should be pruned. One WIP branch must be kept.

Evidence

Verified against the working tree on 2026-07-09.

Local branches to delete (all merged, or duplicates):

Remote branches to delete (origin/…):

Remote branch	Merged via
origin/feat/A2-eval-harness	PR #53
origin/feat/A6-run-governance-bridge	PR #81
origin/feat/epicA-slice1-daemon	PR #82
origin/fix/A2-unicode-confusable	PR #52
origin/feat/epicA-slice4.2-lsm	PR #92 (CLOSED)

KEEP (active WIP): docs/epic-b-macos-windows-detection.

Also present but tied to still-open/draft PRs — do not delete: docs/epic-a-completion-assessment (#125), docs/epic-b-b1-linux-detection (#120), docs/epic-b-b2-b7-slice-plans (#127), docs/epic-b-linux-detection-research (#137), fix/epicA-122-123-honesty (#136), and origin/feature/ultimate-game-stopper (handle via the PR #18 issue).

What to do / Acceptance criteria

1. Before deleting each branch, confirm it is merged (git branch --merged origin/dev / check the PR is MERGED). Do not delete anything with an open/draft PR.
2. Delete the listed local branches (git branch -d, or -D only after confirming merged) and remote branches (git push origin --delete <branch>).
3. Keep docs/epic-b-macos-windows-detection.
4. Acceptance: the listed 16 local + 5 remote branches are gone; only active WIP and PR-backed branches remain; git branch / git branch -r are clean.

Completed against the fresh canonical EXTENDED clone.

Final local state:

• one worktree: /Volumes/EXTENDED/github/ardur-deep-review-20260709
• one local branch: clean, synchronized dev
• the 16 legacy local branches listed in this issue are absent
• 12 additional clean worktrees/branches created by the Phase 0 review were removed after merged/superseded proof

Remote state:

• deleted feat/A2-eval-harness (feat(benchmark): AuditBench eval harness — B1 runnable baseline #53 squash-merged)
• deleted feat/A6-run-governance-bridge (feat(run): zero-setup governance bridge for launched agents (Epic A) #81 squash-merged)
• deleted feat/epicA-slice1-daemon (feat(daemon): ardur-kernelcaptured Slice 1 — always-on eBPF daemon #82 squash-merged)
• deleted fix/A2-unicode-confusable (fix: re-scope unicode confusable check, restore 22/22 Phase-2 conformance #52 squash-merged)
• deleted feat/epicA-slice4.2-lsm (closed feat(enforcement): Slice 4.2 — BPF-LSM enforcement bridge #92, explicitly superseded by merged fix(enforcement): compile-fix Slice 4.2 BPF-LSM, add double-buffer + Linux CI #101)
• also deleted merged review branch gnanirahulnutakki/138-go-1-26-5-cve
• already-closed PR Ultimate Game-Stopper: Phase 1-3 Implementation (Kernel Observability, Evidence Bundles & Semantic Review) #18/docs(roadmap): Epic A completion assessment — NOT DONE (integration gaps #104/#121/#122/#123/#124) #125 branches and review scratch refs are absent; remote-tracking refs were pruned

Because the four old PRs were squash-merged, source-tip ancestry alone was false-negative. Before deletion I verified their current behaviors in dev: benchmark oracle-circularity disclosure/gofmt, hook-to-proxy gap test, CaptureLoss reset/slow-path routing test, and dot-confusable traversal handling.

Preserved: open PR heads for #17, #120, #127, #137, and contributor #182. The named docs/epic-b-macos-windows-detection WIP was not present in this fresh clone or on the live remote, so no operation targeted it.
