# Sixth-handoff reading guide after C479

**Active packet:** `490d_C479_Sixth_Handoff_Compact_Restart_Kit_20260925.zip`.
**Full reference:** `490d_C01_C479_Complete_Window_Archive_20260925.zip`.
**Latest completed:** C479. **C480 unexecuted.**

## Shortest reliable restart

1. Read `490d_Sixth_Handoff_C479_20260925.md` first.
2. Read `490d_C479_Handoff_Archive_Verification_20260925.md` and the direction/correction ledger.
3. Open and verify `controls/FILE_18.md`, `controls/FILE_09.md`, `controls/C265_CERTIFICATE.json`, and the C479 checkpoint/certificate under `active/C479/`. Check actual access; prior sandbox links alone do not establish it.
4. Read the C479 synthesis in that same packet, then the complete report/evidence locator. Do not read every historical report.
5. Return a short access/status summary and a small restart checkpoint, then wait for Dean's instruction unless the new message already authorizes research.

## Immediate C480 dependencies, if later authorized

| Need | Compact location |
|---|---|
| Complete51-coordinate/101-label1150 inventory | `active/C470/evidence/DATA.json` and its report |
| Source bindings of three admitted expansions | `active/C471/` |
| Completed1250 grammar as comparison | `active/C472/` |
| Frozen528-label/373-coordinate register | `active/C470/sources/C286_DATA.json`; full earlier packet at `reference/packets/C286/` |
| Eight fixed E pivots and qualified rule | `active/C470/sources/C450_DATA.json`; `controls/FILE_46.md` lines117–133 |
| Current synthesis, scope and next-step decision | `active/C479/` |

C480 is a finite classification of already frozen1150 pairs. Do not expand the event/pivot menu, resume the superseded AD1905–1911 task, or repeat the finished1250 census.

## Selective earlier reading

All C266–C469 reports are available under `recent_reports/`; C470–C479 have complete active packets. Exact filenames appear in the JSON locator's `compact_report` field. Selected earlier full packets are under `reference/packets/`. Selected milestone checkpoints are under `milestone_checkpoints/`.

`490d_C266_C479_Research_Trajectory_20260925.md` gives a concise guide through these structural advances and their limits. Original unprefixed Mirror reports, Engine reports and C-series reports remain distinct.

## Archive access and verification

The compact kit also retains the earlier C265 compact ZIP. The new full archive contains both the entire C01–C265 archive and the intact September17 complete-study original. Their old instructions and partial-copy warning are historical. Their current hashes and access status are in the new verification record.

Use `python3 verify_handoff_package.py ARCHIVE.zip` to check the included payload manifest and ZIP integrity. This is not a research replay. For selected mathematical replay, follow that packet's README; newer packets use `python3 evidence/check.py --out replay`. Do not run old orchestration/upload scripts. C480 has no packet because it has not been executed.

The enclosing manifest excludes only itself; final archive hashes appear in the separate package receipts. Each preserved research packet retains its own original manifest/certificate. The full archive also preserves original published evidence ZIPs and batch reading/integrity records where available. Current directions override archived next-step paragraphs.
