Memex

Adds a new domain folder with a hub index and wires it into `_MANIFEST.md` -- for a new topic area, or splitting an existing domain into its own folder.

Moves a file from active (Tier 2) to archived (Tier 3) so Memex stops loading it automatically -- for a wrapped project, a stale reference, or a superseded file. The file stays on disk; only its manifest tier and hub status change.

Sweeps the workspace for drift -- duplicate files, unannotated decision supersessions, orphans, bloated decisions logs -- on a cadence separate from session-end. Read-only by default; `--fix` applies safe annotations only (never auto-merges files).

Trigger when the user's question spans multiple Memex workspaces and they don't know which one holds the answer, or they ask "have I written about X anywhere?". Not for questions the current workspace can answer -- use `/memex:search` instead. Reads only manifests and closets, never inside individual files.

Quick-capture an idea to the scratch inbox. Use when the user explicitly asks to capture: "capture this", "add to ideas", "don't let me forget", "log this idea", `/memex:idea`. Not for every "we should eventually..." aside -- most asides aren't capture-intent. Not for decisions (decisions.md) or state claims (closets `claims:` field).

Sets up Memex in the current workspace. Detects state -- fresh repo, existing repo with loose markdown, a foreign manifest, or an outdated version marker -- and runs the right combination of scaffold, scan-and-organize, migrate, or health-check.

Registers this Memex workspace in the global source registry so it's searchable from your other workspaces via `/memex:cross-search`.

Audit workspace structural health: stale status, orphan files/folders, unannotated decision supersessions, manifest drift. Read-only; `--fix` applies safe annotations. Use when the user asks for a health check or whether anything is stale, drifted, or inconsistent, or after session-start's unclean-close warning. Don't fire on vague unease or as a routine session step -- session-start/session-end handle hygiene. Wikilink targets: `/memex:wikilinks` (lint doesn't re-scan links).

Backfills or rebuilds every hub's `_CLOSETS.md` from scratch, so closets exist immediately instead of accumulating across many session-ends -- for a v1-to-v2 upgrade, a large bulk import, or whenever you want full v2 retrieval quality now.

Refreshes manifest and hub summaries to the v2 retrieval-tuned format -- enumerated subjects, named entities, verbatim user-stated facts -- replacing the topic-only v1 style, or catching up summaries after large content changes.

Cross-hub index search within the current workspace: manifest, closets, and the typed-edge graph, grouped by folder, with a built-in similarity pass for fuzzy/paraphrase matches. For cross-workspace search, use `/memex:cross-search`.

Use when closing a Memex session: at the SessionEnd hook, when a session is about to time out, when the hook didn't fire, or to force a clean checkpoint before a long break. Updates memory files, refreshes closets, verifies wikilinks.

Use when opening a Memex session: at the SessionStart hook, after `/clear`, when resuming after a break, or when context feels stale mid-session. Loads tiered context and outputs a briefing.

Removes a Memex workspace from the global source registry -- e.g. after a project is archived or moved -- so it stops appearing in `/memex:cross-search`. For a temporary opt-out instead, use `set-searchable false` (see Gotchas).

Mid-session checkpoint: status/decisions only, no session-log, hub updates, or wikilink checks. Use on an explicit checkpoint ("update memory", "checkpoint progress", "save status", `/memex:update`) or after a significant decision before stepping away. Not for every topic shift or heavy-context moment. For a clean close, use `/memex:session-end`.

Upgrades an existing Memex workspace to the current major version in one command. Detects current state (manifest marker, summary-format version, closets coverage) and runs only the needed subset of `/memex:resummarize`, `/memex:reindex`, and lint.

Verifies wikilink integrity (broken `[[targets]]`), then optionally suggests plain-text-to-wikilink conversions across the workspace. The conversion sweep is a workspace-wide bulk edit, so review suggestions before accepting. For a broader workspace audit (orphans, stale status, manifest drift), use `/memex:lint`.
