## 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 |

| 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 Do not expand the event/pivot menu, resume the superseded AD1905–1911 task, or repeat the finished1250 census.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.

ledger=write(f'490d_C479_User_Direction_and_Correction_Ledger_{DATE}.md',r'''# User direction and correction ledger — sixth handoff after C479

25 September2026. This is a continuity ledger, not a reconstructed verbatim chat transcript. Current explicit directions take precedence over older source-document workflow suggestions. No new research is authorized by this file.

| Direction or correction | Consequence for continuation |
|---|---|
|Continue from the fifth handoff's C265, never restart|Preserve the earlier full C-series, source snapshots, original numbering distinctions and all later work throughC479.|
|Dean's important529 update replaced the originally proposedC266|ActualC266 is the new529 endpoint ledger. AD1905–1911 versus post-Flood MT was superseded before execution and remains outside the active next step.|

|Regular Gears are Noah/Shem/Flood only|No upstream/Creation/Lamech/Arphaxad-forward or cumulative Gear propagation; noG0/G4. Older studies may discuss broader constructions without reopening them.|

## Non-negotiable distinctions

Global pairedMirrorJanuaryAD1 versus localjunctionJanuaryAD2; no civil yearzero. BC pairedbase b=(b+1)t/bn; ADbase a=ADat/(a+1)n. Source-labelled phase pairs differ from bare coordinates. Signed cumulative values are not civil dates. Center expansion with restored phase separation differs from pointwise phase dilation.

K529,E25/23,P70/69; J300/299 is File02 gap conversion, not ResidueProtocol or a general calendar operator. Incoming notationK=25/23 must be translated. Local reflection centers and the twofixedMirror exchanges retain their declared domains.

Source data, selected comparison rules, conditional placement, generated coordinates, theological interpretation and independent historical evidence are different categories. Exact conditional uniqueness does not supply an otherwise unestablished source prescription. Counts of labels, repeated paths, translated configurations and verification assertions are not independent witnesses.

The original C265 direction ledger and fifth handoff remain preserved as historical records. Their still-valid scientific qualifications survive; their old stopping point, next-step proposal and damaged-copy access status do not override this ledger.

verification=write(f'490d_C479_Handoff_Archive_Verification_{DATE}.md',r'''# Sixth handoff after C479 — access, coverage and archive verification

25 September2026. **Fresh artifact checks; no historical research campaign rerun.** Latest completedC479;C480unexecuted.

## Actual access and numbered coverage

| Item | Fresh verification |
|---|---|
|File_18 and File_09|Actual bytes accessible; both controlling SHA256 hashes match.|
|All supplied project-source files|40/40 match the inherited source inventory.|
|C265 checkpoint/certificate|Readable; retained hashes and compact-manifest bindings match.|
|C479 packet|72 manifested payloads,12 certificate bindings,59 frozen source snapshots and their originals verify.|
|C01–C265 complete-window archive|4412 manifested payloads pass;265 report hashes and result hashes match the locator.|
|C266–C479 complete packets|214/214 present;6369 sealed payloads verify; every report/results record matches its certificate and records a passing result.|
|Predecessor continuity|213 internal links C266→C479 plus the C265→C266 baseline link verify:214 links in total.|
|Canonical graph|Unchanged;208 nodes and382 duration edges.|

All479 canonical reports and result records are available. C130's downstream-selected Primary_Circuits packet and alternate Dependent_Mirror_Closure remain distinct. For C266, checkpoint authentication is through its payload manifest; the other213 new checkpoints have explicit certificate hash bindings.

Passing research results are inherited sealed records, not479 newly executed calculations. Earlier source-review/replay counts retain their original meaning. This handoff's independent artifact and continuity reviews do not establish independent historical witnesses or design intent.

## The September17 original is now intact

| Property | Verified current original |
|---|---|
|Bytes|159,771,259|
|SHA256|`a24741428ab6b1f88577b4571597b442dd35d069664e56dd1e29c3c354157a19`|
|ZIP integrity|Pass|
|Manifest payloads|2068 pass|

This exactly matches the expected original recorded before the earlier local partial-copy problem. The old146,961,408-byte partial file and its warning remain historical, not the current status. The new full archive embeds the intact original unchanged. No reattachment of the damaged copy is needed.

The immutable C01–C265 archive is105,886,952bytes, SHA256`a76c7e9d1ed130d95c827fe208192a18230a0e92f951a39e454550b9d5403e64`; its4412 payloads pass. It preserves the original unprefixed ten-step Mirror ZIP, prior recovery/review archives and its full report locator. Eight older nested reference ZIPs were authenticated by recorded or enclosing-manifest hashes and checked for fresh CRC integrity. Their internal manifests were not all separately re-audited.

Original unprefixedReports01–10 remain the separate preserved foundation. Original interruptedReports11–25 remain unestablished. The four Engine reports and two differentReportV studies are separate source-literature numbering. No missing original sequence is silently filled by C-numbered reports.

## New package verification

Both new packages contain `PACKAGE_MANIFEST.json` recording every other payload's exact path,size andSHA256. `verify_handoff_package.py` verifies this manifest and ZIP CRC without running research. The build also checks that every new locator path resolves to the intended report/result bytes. The separate `490d_C479_Handoff_Package_Receipts_20260925.json` gives the final package sizes, hashes and payload counts; it is outside the archives to avoid a self-hash cycle.

The compact kit is an explicitly selected working subset, recorded by `COMPACT_FILE_MAP.json`. The full archive includes all214 normalized C266–C479 packets, original published evidence ZIPs, batch indexes/integrity records, all40 source files, the supplemental input bundle, and the two intact older reference libraries. Private transfer credentials/logs and runtime caches are excluded. No scientific report is omitted by those exclusions.

Audit details are retained under `audit/`: `ACCESS_ARCHIVE_VERIFICATION.json`, `C266_C479_COVERAGE.json`, the unified locator, source inventory, and the baseline-link record. Recorded absolute original-workspace paths are provenance; use the package map for portable access.

This handoff changes no source,date,phase,pivot,operator menu,global axis,primer status or graph. **C479 complete; C480 unexecuted.**

opening=write(f'490d_C479_New_Chat_Opening_Prompt_{DATE}.md',r'''This is the **sixth handoff of the existing490d Unified Chronology research**, continuing through **C479**, not a restart.

Read **`490d_Sixth_Handoff_C479_20260925.md` first**, then the new reading guide, archive verification, direction/correction ledger and C01–C479 report/evidence locator. Use **`490d_C479_Sixth_Handoff_Compact_Restart_Kit_20260925.zip` as the active working packet**. Treat **`490d_C01_C479_Complete_Window_Archive_20260925.zip`** and its intact nested older archives as reference libraries; inspect indexes and retrieve dependencies selectively. Current corrections and scope decisions override stale archived instructions and old next-step paragraphs.

Verify actual access to File_18,File_09 and the C479 checkpoint, with C265 continuity preserved. Verify report/evidence availability through the supplied locators and integrity records without reading every historical report. C01–C479 are distinct from original unprefixedReports01–10, the unestablished interrupted originalReports11–25, and the comparative Engine reports. The September17 original is now intact and hash-verified; its old partial-copy warning is superseded.

Keep the **Mirror and529 focus**; regular Gears remain **Noah/Shem/Flood only**. The original proposedC266 AD1905–1911 check was superseded; actualC266 began the important529 update. Preserve both supplemental LXX8464 corrections and the SKL appendix without redirecting research.

**C480 has not been done:** it proposes reducing the existing51-coordinate/101-label1150 interval inventory to disjoint source-role/context templates and explaining the three admitted fixed-E expansions. Do not add dates,pivots,phases or operators.

First return a concise access/status summary and a small restart checkpoint, then wait for my instruction before new research. During later authorized batches, reassess after each bounded result and publish completed reports and incremental evidence checkpoints as work proceeds.
