# Contract note — 1a16c508 · Full-fidelity evolution (Stage 1 PRESERVATION)

Saved 5 Sep 2026 ~00:26 Europe/London. Extends UUID **1a16c508**. Janhavi + ChatGPT directive. Shadow work only.

## What this is
Full-fidelity **shadow evolution** of the historical FYJ corpus into the Dev experience model — without discarding live production content and without cutting over.

Pipeline: **PRESERVATION → RECONCILIATION → EVOLUTION → VERIFICATION → APPROVAL**.

This file marks **Stage 1 PRESERVATION** (inventory + contract + zero-loss scaffolding).

## Roles (do not collapse)
| Role | Meaning |
|------|---------|
| **OLD SYSTEM** | Historical source-of-truth corpus. Authoritative production until explicit approval cutover. Especially live `/founder/visibility/`. |
| **DEV / MOCKUP** | Target **experience** model only (`html-explainers/dev/v1/`). Not a replacement corpus. |
| **NEW SYSTEM** | Complete historical corpus expressed through evolved interaction — built as **shadow beside live**. |

## Invariants
- Do **not** rebuild from Dev/mockup alone.
- Do **not** treat `/founder/visibility/` (live) as disposable.
- **Zero-loss:** every meaningful object accounted for (may be superseded / historical-only / merged — never silent discard).
- Do **not** mutate live Founder/Agent Views. Do **not** cut over.
- Do **not** invent narrative bridges — mark **NARRATIVE GAP**.
- Do **not** invent customer / path / P; do **not** unpark **63e813ea**; parked stays silent state.
- Site v2 remains paused. Do not wipe `/var/www/fyj-notes`.

## Honesty floor (unchanged)
P empty · no named path · cut 63e813ea silent parked · compile 0 · blocker reach · live team founder only · Current slot unchanged · no assemble · no invent customer.

## Stage 1 artefacts
Manifests under `/workspace/fyj-dashboard/html-explainers/dev/migration/`:
- `00-README.md` — process + invariants
- `01-inventory-summary.md` — counts by type
- `01-inventory-files.jsonl` / `01-inventory-dirs.jsonl`
- `02-zero-loss-template.md` / `02-unresolved.md`
- `03-parity-checks.md`

## What this is not
- Not a publish of a finished NEW SYSTEM.
- Not a rewrite of Dev pages into the migration yet.
- Not a merge into live Founder/Agent Views.
- Not Site v2 work.

## Prior companions under 1a16c508 family
- `1a16c508-frontier-schedule.md` — frontier + schedule feedback
- `b7e2d19a-cuts-forward.md` — cuts-forward / silent parked
- `a4e8c12f-dev-v1-contract.md` — Dev V1 cream surface

Confirmation: Stage 1 PRESERVATION contract on agent attention. Live Founder/Agent Views untouched. Shadow only. Zero-loss scaffolding at migration/. Site v2 paused. P empty. Cut 63e813ea silent parked.
