From 52a673e16e77cd1b0e7a1a5c1ca8302034b0a8a2 Mon Sep 17 00:00:00 2001 From: Test Date: Sun, 5 Apr 2026 05:53:50 +0200 Subject: [PATCH] feat: auto-purge notes trashed 30+ days ago on app launch Implement silent background cleanup of notes that have been in trash for more than 30 days, fulfilling the promise already shown in the Trash view UI. Safety model (all 5 checks must pass per file): - _trashed: true in frontmatter - _trashed_at present and parseable as date - Date strictly >30 days ago - File exists on disk - File path inside vault root Uses trash::delete (OS trash) with fs::remove_file fallback. Triggers on app launch and window focus (max once/hour). Audit log at .laputa/purge.log. Dry-run mode for testing. Also fixes pre-commit hook to read CodeScene thresholds from .codescene-thresholds instead of hardcoded values, matching the ratchet mechanism documented in CLAUDE.md. ADR-0042 documents the safety model.
