# MIGRATION_ID_MAPPING — Phase 4 (deletion-pending)

> ⚠️ **LLM-targeted deletion reminder**: This file was a Phase 4 transient artifact for the ID-format migration. **From 2026-05-10 onward** (2 weeks after Phase 5 completion 2026-04-26), any LLM agent that reads this file MUST surface the following single-line reminder to the user at the start of its next response:
>
> *"`MIGRATION_ID_MAPPING.md` is past its 2-week retention window (since 2026-05-10) — confirm if you want me to delete it now."*
>
> Until 2026-05-10 the file remains untouched as a reverse-lookup aid (git history, old chat transcripts, external references may still mention OLD IDs).
>
> **Phase 4 of the ID-format migration** (see `LLMP-DEC-50`). Maps existing 3-component IDs (`<TOPIC>-<TYPE>-<N>`) to the new 4-component format (`<PREFIX>-<TOPIC>-<TYPE>-<RAND>`).
>
> **Status:** generated 2026-04-26; Phase 5 (per-topic rename) completed 2026-04-26; Phase 6 (cross-ref cleanup) consumes this table. **Original Phase 7 plan (delete this file) is superseded** — this file now persists as a historical reverse-lookup aid, with a 2-week deletion-review window starting 2026-05-10 (per user instruction 2026-04-26).
>
> **Generation rules:**
> - Repo prefix per `REPO_PREFIXES.md` (file → repo → prefix).
> - Random 4-char `[A-Z0-9]` suffix; unique within each `<PREFIX>-<TOPIC>-<TYPE>` triplet.
> - `LLMP-DEC-N` entries are NOT migrated (workspace-meta exception).
> - Template/placeholder IDs (e.g. `## GRID-I-1: ...` example line, `AUTH-I-N` placeholder) are NOT migrated.
> - "Pending" references (mentioned in docs but not yet defined as `_ISSUES.md`/`_TODO.md` entries) are NOT migrated — see "Pending forward-references" section below; they get rewritten/removed in Phase 6.

## ACBLAZOR — AyCode.Blazor

### MGGRID (GRID)

Canonical home: `AyCode.Blazor.Components/docs/MGGRID/MGGRID_TODO.md`. (No issues yet — `MGGRID_ISSUES.md` only contains a placeholder example line.)

| OLD_ID | FILE (repo-relative) | NEW_ID |
|---|---|---|
| `GRID-T-1` | `AyCode.Blazor.Components/docs/MGGRID/MGGRID_TODO.md` | `ACBLAZOR-GRID-T-V4P7` |

## Pending forward-references (NOT migrated — Phase 6 cleanup)

These IDs are referenced in docs but not yet defined as `_ISSUES.md`/`_TODO.md` entries. They have no OLD_ID body to migrate. Phase 6 must decide per-case: (a) actually create the entry under the new format, or (b) rewrite/remove the reference.

| Referenced ID | Mentioned in | Decision deferred to Phase 6 |
|---|---|---|
| `LOG-T-12` | `docs/AUTH/README.md`, `docs/adr/0001-user-bearer-token-flow.md` | Tentative TODO ("Never log secrets" framework guideline). Either define as `ACCORE-LOG-T-<RAND>` and add to `LOGGING_TODO.md`, or rewrite reference. |
| `SBP-T-9` | `AyCode.Services/docs/adr/0001-acbinary-decorator-feature-stack-design.md` | Reserved for `AcHubProtocolDecoratorBase` impl + handshake; deferred until at least one leaf ADR (0002-0005) reaches `Status: Accepted`. Either define on demand or rewrite reference. |

## Template/placeholder IDs (NOT migrated)

These appear in template/example lines, not as real entries. They stay as-is (or get reformatted to the new placeholder syntax in Phase 5 alongside the topic rename).

| Placeholder | File | Note |
|---|---|---|
| `GRID-I-1` | `AyCode.Blazor.Components/docs/MGGRID/MGGRID_ISSUES.md:7` | Example line: "Add the first `## GRID-I-1: ...` entry below..." — should become "`## ACBLAZOR-GRID-I-<RAND>:`" example. |
| `AUTH-I-N` | `AyCode.Core/docs/AUTH/AUTH_ISSUES.md`, `AyCode.Core/docs/AUTH/README.md` | Generic placeholder — the `N` is literal "N", not a digit. Should become `ACCORE-AUTH-I-<RAND>` example. |

## Workspace-meta IDs (NOT migrated — bare exception)

`LLMP-DEC-N` Decision Log entries do NOT receive a repo prefix per `REPO_PREFIXES.md` "LLMP exception" section. They stay bare. Highest entry as of 2026-04-26: `LLMP-DEC-55` (Phase 3 closure).

## Within-triplet duplicate-check (sanity)

| Triplet | Count | Suffixes (sorted) | Unique? |
|---|---:|---|---|
| `ACCORE-BIN-I-` | 15 | B4Y7, D2J5, F1W8, G7N3, H2C5, J4D2, K8R4, L7G3, M3K6, N6Q3, P3M6, R5V9, S1F8, T9X1, V5L2 | ✅ |
| `ACCORE-BIN-T-` | 4  | Q2N7, S8P4, T5J8, W9F1 | ✅ |
| `ACCORE-LOG-I-` | 10 | B2H5, K1Z7, K7M2, L4N8, M4C9, P5W3, R9P3, T8F2, V3J6, X7Q1 | ✅ |
| `ACCORE-LOG-T-` | 11 | B8K5, F4S6, H6Y4, J9G2, L3T8, M7P2, N2D8, Q6Z1, R7L3, W4H9, X1V4 | ✅ |
| `ACCORE-SBP-I-` | 2  | F6T2, G4B5 | ✅ |
| `ACCORE-SBP-T-` | 8  | B3K6, H7M5, J5W8, K3J7, L1V4, N9F3, P8X9, R6D2 | ✅ |
| `ACCORE-SIG-I-` | 9  | B5G9, H8D6, K6F1, L5K3, N3V8, P1J4, R4W7, T7S2, X4M7 | ✅ |
| `ACCORE-SIG-T-` | 6  | D7Q4, J2P5, M5L6, S3N8, V9H1, W8R3 | ✅ |
| `ACCORE-TOON-I-` | 4 | B7L4, K4Z9, P6V5, X3H2 | ✅ |
| `ACCORE-TOON-T-` | 7 | D1R7, F3X1, G5M3, J8N6, M9Q2, S6B9, V2T4 | ✅ |
| `ACCORE-XCUT-I-` | 1 | X8Q1 | ✅ (trivially) |
| `ACBLAZOR-GRID-T-` | 2 | S2L9, V4P7 | ✅ |

All 12 triplets pass uniqueness within-triplet (the only collision domain that matters per `REPO_PREFIXES.md`'s suffix specification — collisions ACROSS triplets are non-issues since the full ID disambiguates).

## Phase 5 readiness checklist

For each topic-pair (`_ISSUES.md` + `_TODO.md`) Phase 5 will:
1. Rename headers (`## LOG-I-1: ...` → `## ACCORE-LOG-I-K7M2: ...`).
2. Rewrite intra-file cross-refs (e.g., body text "see LOG-I-3" → "see ACCORE-LOG-I-L4N8").
3. Rewrite TOC/anchor references if present.
4. Verify with grep: zero remaining bare `<TOPIC>-<TYPE>-<N>` matches in the file (post-rename), excluding example/placeholder lines.
5. One commit per topic (12 commits total: BIN, LOG, SBP, SIG, TOON, XCUT, GRID — but BIN/LOG/SIG/SBP/TOON each pair I+T → 5 commits; XCUT and GRID each 1 commit → 7 commits total).

Inter-file cross-refs (e.g., `BINARY_ISSUES.md` mentioning `BIN-T-3`, `BINARY_TODO.md` mentioning `BIN-T-3` from another entry, ADRs mentioning `LOG-I-9` etc.) are handled in Phase 6.
