+:::caution[Branch reset caveat]
+The migration branch periodically fast-forward-resets when main merges. Each Autoloop iteration rebuilds lost modules before adding new ones. `benchmarks/migration-status.json` reflects the iter-13 stable baseline (24 modules, 4,245 lines). Iteration 24 committed an additional 30 Go packages on top of that baseline; those modules are not yet captured in the JSON. The machine-state `best_metric` of 9.89 corresponds to ~7,092 migrated lines and is the authoritative progress signal.

-## Benchmark snapshot
+## Benchmark signals
 
-Autoloop's current migration metric is `python_lines_migrated_pct`: `(migrated_python_lines / original_python_lines) * 100`. The latest recorded status file on the migration branch reports 827 migrated lines out of 71,696 total, or 1.15%.
+### Migration metric
 
-### Manifest operations benchmark
+Autoloop tracks `python_lines_migrated_pct = (migrated_python_lines / original_python_lines) * 100`. The best recorded value is **9.89%** (iteration 24, ~7,092 of 71,696 lines). `go build ./...` and `go test ./...` pass on all accepted iterations. Module-specific Python-vs-Go timing data is not yet present in `benchmarks/migration-status.json`.
 
-The existing `scripts/benchmark_manifest_ops.py` benchmark measures Python manifest operation optimizations that remain relevant while Go parity work advances.
+### Manifest operations benchmark (`scripts/benchmark_manifest_ops.py`)
+
+Run locally on 2026-05-13 with `python3 scripts/benchmark_manifest_ops.py`. Results are nondeterministic micro-benchmarks; order-of-magnitude values are stable across runs.
 
 | Scale | `check_collision` speedup | `sync_remove_files` speedup | `cleanup_empty_parents` speedup | Scoped uninstall speedup |
 |---|---:|---:|---:|---:|
-| Current: 10 packages, 50 paths | 21.6x | 1.9x | 1.0x | 1.7x |
-| Growing: 50 packages, 250 paths | 85.4x | 1.7x | 0.6x | 9.7x |
-| Large monorepo: 100 packages, 2,000 paths | 519.8x | 1.7x | 0.5x | 20.5x |
+| Current: 10 pkgs, 50 paths | 24.9x | 1.8x | 0.9x | 2.0x |

+| Large monorepo: 100 pkgs, 2,000 paths | 923.3x | 1.7x | 0.5x | 24.2x |
+
+`cleanup_empty_parents` shows a small regression at scale (0.5x–0.9x) because the batch bottom-up algorithm has higher constant overhead than the legacy per-file walk-up at low deleted-file counts. This is expected and acceptable given the gains on the other three operations.
 
-### Go validation signals
+### Go build/test validation
 
-The Autoloop memory records that the Go module builds cleanly and `go test ./...` passes on accepted iterations. Module-specific Python-vs-Go timing data is not yet present in `benchmarks/migration-status.json`; the progress workflow should publish those timings here once Autoloop starts recording them.
+| Signal | Status | Notes |
+|---|---|---|
+| `go build ./...` | Pass (all accepted iters) | Confirmed in iter-13, iter-22, iter-23, iter-24 notes |
+| `go test ./...` | Pass (all accepted iters) | Confirmed in iter-13, iter-22, iter-23, iter-24 notes |
+| External deps | Unavailable in sandbox | `gopkg.in/yaml.v3` blocked; stdlib-only YAML scanner used for `workflow/parser` and `deps/aggregator` |
 
 ## Next up
 
-The Autoloop memory identifies these likely next targets:
+From the Autoloop memory `Future Directions`:
 
-- `utils/content_hash.py`: SHA-256 tree hashing.
-- `utils/exclude.py`: gitignore-style file exclusion.
-- `utils/console.py`: CLI output helpers.
-- Eventually wire Go packages into the Python CLI via subprocess or replace the entry point.
+- `install/pipeline.py` (741 lines), `install/sources.py` (734 lines), `install/services.py` (734 lines) -- larger install modules, clear patterns.
+- `policy/discovery.py` (1,365 lines) -- highest-impact policy module.
+- `deps/github_downloader.py` (1,686 lines) -- requires HTTP client work.
+- `install/phases/finalize.py` (92), `install/template.py` (140), `install/service.py` (146) -- smaller fill-in modules.
+- Wire Go packages into the Python CLI via subprocess or subprocess-replacement.
+- Address recurring branch-reset issue: consider a stable upstream merge strategy so `benchmarks/migration-status.json` stays current.
 
 ## Operating notes
 
-- Prefer leaf modules first; they have fewer internal APM dependencies and lower integration risk.
-- Keep Go implementations stdlib-only when sandbox networking blocks external module fetches.
-- Continue recording every accepted iteration in `benchmarks/migration-status.json` so this page can report real migration and benchmark data instead of estimates.
+- Prefer leaf modules first; fewer internal APM dependencies and lower integration risk.
+- Keep Go implementations stdlib-only when sandbox networking blocks external module fetches (e.g., use a line-scanner for YAML frontmatter instead of `gopkg.in/yaml.v3`).
+- Record every accepted iteration in `benchmarks/migration-status.json` so this page can report complete module data.
