What changed

las refresh ~/code/notes-api     # analyse again and compare with the previous analysis
las history ~/code/notes-api     # one line per previous analysis

Every real analysis (not one served from cache) saves a snapshot in .localalibi/history.db: date, git HEAD if any, every claim, and every file with its hash. las refresh analyses again and translates the difference into architecture language:

New
  + Service: OpenAI  ← src/services/summary.ts:1
  + New route DELETE /notes/:id  ← src/routes/notes.ts:16

Changed
  ~ Routes: 1 file changed  ← src/routes/notes.ts
  ~ Service OpenAI: 1 new file  ← src/services/summary.ts

Alerts
  ⚠ README does not mention OpenAI yet  ← src/services/summary.ts:1

Sign	Meaning
+	new services, databases, ORMs, frameworks, routes and dependencies
-	the same, removed — and important files that were deleted
~	a status changed (SQLite: ✓ confirmado → ≈ inferido), and changed files grouped by the component they belong to ("Base de dados SQLite: 2 ficheiros alterados"), or by folder
⚠	new contradictions, and new services/databases the README doesn't mention yet

It works without git: changes are detected from file hashes. In a git repository the HEAD is recorded too.
