# Archive Index — implementer-backend (L2 catalog, NO content)

> **Purpose:** rescue L2 archive "dark-matter" (not in RAG). One line per archived record so a reader can locate + Ctrl-F the verbatim text. This index holds NO record bodies — see `<file>.gist.md` for 4-field distillations, and the named archive file for full verbatim.
> **Pointer style = substring (Ctrl-F) PRIMARY.** Each row ends `substring:"…"` — a string that greps UNIQUE (count=1) inside its target file. Open the file, Ctrl-F the string, land on the record. Fallback hint = the record's `## /### ` heading (date + session). NO line-number hints (archives are frozen but line numbers drift if ever re-touched).
> **Why not date pointers:** dates COLLIDE — q1 has 5× `2026-05-14` + 4× `2026-05-15` + 2× `2026-05-13`; q2 2× `05-19` + 2× `05-22`; q3 4× `05-22`; q4 3× `05-26`. So every pointer is keyed on a git-SHA (`cdfd542`/`0bf6c7e`/`06a441c`/`62b50d1`) or a distinctive Mig-name / phrase, never the bare date.
> **Archives are FROZEN / additive-only.** `2026-05-q1..q4.md` are verbatim history (do NOT edit). `2026-06.md` (new, Harness-9 curate) holds 14 bullets moved byte-exact out of MEMORY.md L87-L104.
> **Labels:** `[meta]` = curate/governance/setup note (low code value). `[stub→git]` = FIFO-trim stub whose real content lives in git `d2f52ba` (do not expect rich body).
> **Sorted by DATE** (ISO 05-xx first; then session-keyed S41→S55 records in `2026-06.md`, which are chronologically post-`05-26`).
