# Patch Memory

`PATCH /v1/memories/{path}`

## Request

- Base URL: `https://api.heirmos.com` (the document declares no server; this is the origin it was published from)
- URL: `https://api.heirmos.com/v1/memories/{path}`
- Auth: HTTP bearer

## Path parameters

- `path` string, required

## Request body

- MemoryPatch: PATCH /v1/memories/{path:path} request — SPEC §5.3 line 360-379. 본문은 `content` (Mode A — full replace) 또는 `edits` (Mode B — surgical str_replace) 중 **정확히 하나**로 바꾼다. 둘 다 생략하고 `title` 만 보내면 제목만 바뀐다(본문 불변) — 2026-08-23, 그전까지 제목은 생성 시에만 정할 수 있어서 "이름 바꾸기" 가 불가능했다.
  - `content` string, nullable
  - `edits` MemoryEdit[], nullable
    - `old` string, required
    - `new` string, required
  - `title` string, nullable

## Response `200`

Successful Response

- MemoryRead: GET /v1/memories/{path:path} response — SPEC §5.3 line 326-339. `summary` is included even though SPEC's example omits it: the column exists (SPEC §4.1) and list responses surface it, so a single-memory read should too.

  - `dedup` DedupInfo: Advisory write-time dedup result — Phase 13 P13-2 (SPEC §10 + §15 #17). Rides on the ``POST /v1/memories`` response body **only** (never persisted). The server always saves the memory (201); this tells the client/user that the new memory resembles an existing one so they can choose to merge into ``suggested_path``. Propose-only — the server never blocks or auto-mutates.
    - `relation` 'same' | 'similar' | 'related' | 'conflicting' | 'new', required
    - `suggested_path` string, nullable
    - `rationale` string
    - `similarity` number, nullable

## Other responses
