strata-archive

name	strata:archive
disable-model-invocation	true
description	Move merged branches' pr-context dirs into archive/. User-only — run when the user explicitly asks to "clean up old branches", "archive merged work", or "tidy the vault". Never deletes, only moves, but it mutates the vault and changes what recall returns, so it does not auto-invoke (matching forget / export-to-repo / promote-to-pr). Detects merged branches via `gh pr list --state merged` or `git branch --merged main` fallback.

strata:archive

PR-context notes accumulate as branches merge. This skill moves stale Working notes out of pr-context/ and into archive/<merge-date>--<branch>/ so the search/index reflects active work.

When to use

• Periodically (weekly is fine).
• Before a release, to leave a clean snapshot.

How

# See what would happen, no mutation
"${CLAUDE_PLUGIN_ROOT}/bin/strata" archive --dry-run

# Apply
"${CLAUDE_PLUGIN_ROOT}/bin/strata" archive

Strategies (auto-selected, override with --strategy):

• gh — queries gh pr list --state merged and matches by headRefName. Most accurate (uses real merge dates).
• git — git branch --merged <main>. Works without gh; uses today's date as the archive date.

Pass --main-branch develop if your trunk isn't main.

What it doesn't do

• Doesn't delete anything — moves only.
• Doesn't archive decisions/, lessons/, or domain/ — those are durable.
• Doesn't unwind itself; restore by moving back from archive/.
