# /wheypoint `/wheypoint` captures just enough state for a cold reader to resume. `/wheypoint` is for culture's end-of-session checkpoint and for the messy mid-task moment when no phase slug applies and context is about to be lost. ## Inputs - The conversation so far (the primary input). - Optional argument: a description of what the next session will focus on. When present, treat it as the lens and tailor the document to it.

Reads both notes from `.cheese/notes/` and writes a single merged note whose `parents:` lists both slugs. - Optional verb `--split`: fork the current thread into two resumable tracks. Writes two child notes, each with `parents: [<current-slug>]` and a distinct slug. ```text /wheypoint -> one note with session/git/created auto-filled /wheypoint --join A B -> one merged note, parents: [A, B] /wheypoint --split -> two child notes, each parents: [<current>] ``` ## Flow 1. **Derive a slug** from the task (e.g. `auth-retry-backoff`). Reuse an existing slug if this session already owns one under `.cheese/`. 2. **Inventory what already exists.** List the `.cheese/` artifacts, specs, PRs, issues, commits, and diffs this session produced or touched. These get referenced, never re-summarised. 3. **Write the handoff document** to `.cheese/notes/<slug>.md` with the slug he
