lossless-migration skillA

lossless-migration is agent-read markdown (skill) from tjcages/skills: Inventory-before-rewrite: map every table/endpoint/engine/UI to a destination tag, prove zero regressions, retire only when replacement is live. Use when migrating/reframing an existing product, consolidating AI engines, or the user asks for an inventory audit / lossless migration / “don’t lose anything.” NOT for green-field apps with nothing to preserve..

Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.

What the file says

# Lossless migration

Chat: [RESPONSE.md](./RESPONSE.md). Full method: [METHODOLOGY.md](./METHODOLOGY.md).

## Operating order

### 1. Migration or skip? (§1)

Green-field / toy → skip. Existing users/behaviors → continue. No constitution → hand to `constitution-first` first.

### 2. Wire the trio (§2)

Constitution (why) · inventory audit (proof) · roadmap (phases). Confirm conflict rule.

### 3. Enumerate (§4.1)

Data · endpoints · engines · UI · primitives · one-offs. Breadth before deep mapping.

### 4. Tag every row (§3–§4.2)

One primary destination tag + one-line mapping. Escalate unknowns — no silent skips.

### 5. Verdict + GAP/RETIRE (§4.3–§4.4)

Reframe % · consolidate % · GAP list · RETIRE list (supersede + phase).

### 6. Engine collapse if needed (§5)

Cluster AI/functions into one registry; old callers thin then die.

### 7. Roadmap + score (§6–§9)

Invisible→visible→scrub. Rubric ≥12/16, no 0 on #1–#5. Log EXAMPLES.md same day.

### 8. Hand off

Phases → `linear-setup`. Agent writes → `accept-gated-ai`. Multi-platform parity → `behavior-contracts`.
