Priority 1: Daily backup automation via Dagu DAG (~/dagu/dags/fn_backup.yaml,
schedule "0 3 * * *"). Backs up registry.db, each operations.db, and vaults
via rsync --link-dest. Fixes set -e arithmetic bugs in rotate_backups.sh and
backup_all.sh ((var++) returns 1 when var=0). Fixes && chain set -e bug in
vault rotation.
Priority 2: Pre-commit hook v2 chains scan_secrets + uses_functions audit.
New function git_hook_audit_app_drift_bash_infra blocks commits that touch
app code when that app has uses_functions drift. Allows corrective app.md-only
edits. Installed on fn_registry + 32 sub-repos.
Priority 3: Synced uses_functions in 6 sub-repo apps (commits in their own
repos): dag_engine, script_navegador, deploy_server, docker_tui,
auto_metabase, metabase_registry. Drift went from 7/12 to 4/12 apps.
Remaining drift = audit heuristic limitations (Python nested imports,
Go symbol name detection).

Adds `fn doctor` read-only diagnostic command with subcommands artefacts,
services, sync, uses-functions, unused, and --json flag for agents.
Each subcommand wraps a registry function in functions/infra/.
New functions:
- artefact_doctor, services_status, pc_locations_drift,
audit_uses_functions, find_unused_functions (Go diagnostics)
- backup_sqlite_db, rotate_backups, wait_for_http, wait_for_port,
port_kill, tail_journal, pre_commit_hook_install (bash utilities)
- notify_telegram (Go HTTP)
- backup_all pipeline (tag launcher)
Plus prior session leftovers (scan_secrets_in_dirty, append_diary_entry,
git utilities, http_session_cookie_middleware, compile/full-git pipelines).
Fixes pc_locations_drift filepath.Join bug with absolute dir_path.
Documents fn doctor in CLAUDE.md, .claude/rules/fn_doctor.md (rule 23),
docs/architecture.md, CHANGELOG.md (2026-05-07), and diary entry.
First fn doctor uses-functions run found drift in 7/12 apps (deuda
para sincronizar app.md con imports reales).
