description	OverKill Hill P³ ChatGPT project migration. Use when migrating, preserving, extracting, inventorying, normalizing, reconciling, or incorporating ChatGPT project threads, conversation exports, or complete chat histories into a repository. Also activate when a user needs a lossless thread archive, project-to-export crosswalk, provenance ledger, or public-safe distillation workflow. This is the authoritative capture and reconciliation process for ChatGPT project material in this repo -- use it even when the user asks only to "save", "review", or "summarize" a large set of threads.

Capture a ChatGPT project as evidence before transforming it. This skill keeps the source corpus intact, proves which threads and turns were captured, and only then routes reviewed material into durable repository artifacts.

Scope

In scope	Out of scope
Exporting and indexing accessible ChatGPT project threads	Recovering deleted or permission-restricted content
Preserving every exported message node and content part	Treating an LLM summary as source preservation
Reconciling source material with repository artifacts	Publishing raw chats, credentials, or third-party private data
Optional Notion status register	Making Notion the authoritative raw archive

---

Operating principle

Use a two-lane process:

1. Source lane: immutable export, project inventory, normalized transcripts, hashes, and exception records. Keep it local and out of Git.
2. Artifact lane: reviewed, classified, public-safe Markdown and structured artifacts committed to their proper repository locations.

Do not substitute artifact-lane summaries for source-lane records. A source record may be distilled many times without changing the original evidence.

---

Required inputs and first decision

Record the project URL, capture date, account/workspace type, intended archive location, and publication sensitivity. Treat repository visibility as unknown unless the owner has resolved it.

Use ChatGPT data export as the primary source when available. It is faster and more complete than manually copying UI text. Use Browser to enumerate the target project and verify it against the export. Use Computer only for UI actions that Browser cannot complete, such as a download dialog or desktop-only control.

If the account cannot export data, proceed with Browser-based recovery but mark the batch ui_capture_only and list its reduced-fidelity limitations.

Capture procedure

1. Preserve the original

Store the downloaded export ZIP in an owner-controlled local archive outside the repository. Do not rename, edit, or unpack the only copy. Calculate and record raw_sha256 before working with it.

Create a disposable working copy under custom-gpts/ingestion/. That location is Git-ignored, but it is a staging area, not the permanent archive.

2. Inventory the project UI

Enumerate every accessible thread in the target project. For each thread record the stable conversation ID from its URL, displayed title, project URL, observed last activity, attachments or images, and UI-capture status. Do not use title matching as the primary key.

Write project_capture_manifest.json following references/source-manifest-schema.md. Assign each row one of: inventoried, captured, normalized, reconciled, routed, exception.

3. Normalize without flattening

Parse every conversation record into a normalized transcript and retain the raw JSON record. Preserve all nodes in the conversation mapping, including regenerated alternatives and non-current branches. Do not serialize only the current_node path.

For every message node retain: node ID, parent ID, child IDs, role, create and update time, author metadata, content parts in order, attachments, tool or citation metadata when present, and a source locator. Represent unavailable fields as null; do not invent values.

4. Reconcile and recover exceptions

Match project inventory rows to normalized export records by conversation ID. Record a one-to-one match, one-to-many ambiguity, or no match. Do not silently drop unmatched rows.

For every no_match or missing asset, use Browser-based capture as the recovery path. Preserve the URL, capture time, and reason for the exception. Keep the exception open until it has a source record or the owner accepts the loss.

---

Completion gates

Do not call a migration complete until all are true:

• Every inventoried thread has a conversation_id and a disposition.
• Every captured source has a raw_sha256 and a normalized-record hash.
• The parser counted all conversation mapping nodes, not only visible turns.
• Every unmatched thread, branch, message, or asset appears in exceptions.
• Raw source material remains outside tracked repository paths.
• Every committed artifact links to a source reference, a review decision, or an explicit statement that it is an original new artifact.

Report coverage as counts: threads inventoried/captured/reconciled, mapping nodes retained, assets retained, and open exceptions. Do not claim 100% unless the exception count is zero and the owner accepts the inventory boundary.

---

Integration and routing

Classify each candidate before writing to the repository:

Class	Destination	Handling
Raw evidence	Local archive and ignored staging	Preserve verbatim; never commit by default
Historical reference	custom-gpts/proto/ or a clearly marked archive	Retain provenance and version context
Durable method	custom-gpts/consolidated/, docs/, or a skill	Distill, deduplicate, and cite source IDs
Operational artifact	Relevant schema, example, skill, or child-repo material	Add acceptance checks and ownership
Private or unsafe material	Local quarantine record	Redact, omit, or obtain explicit owner approval

Use Notion only as an optional private Corpus Register for batch status, hashes, source locations, routing decisions, and review notes. Do not copy the entire source corpus into Notion merely to make it searchable.

When processing already captured Custom GPT material, use the existing corpus ledger and evidence-register conventions. Preserve disagreement and historical versions rather than making repetition appear authoritative.

---

Required handoff report

Return a concise report with:

Batch: <project name and capture date>
Source: export | ui_capture_only
Threads: <inventoried> inventoried / <captured> captured / <reconciled> reconciled
Nodes: <retained> retained
Assets: <retained> retained / <unavailable> unavailable
Exceptions: <count>
Artifact routing: <destinations and counts>
Owner decisions needed: <list or none>
