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). Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

## Ejemplo
|
|
|
|
```go
|
|
statuses, err := ServicesStatus("/home/lucas/fn_registry")
|
|
if err != nil {
|
|
log.Fatal(err)
|
|
}
|
|
for _, s := range statuses {
|
|
fmt.Printf("%s unit=%s port=%d listening=%v\n",
|
|
s.Name, s.UnitActive, s.Port, s.PortListening)
|
|
}
|
|
```
|
|
|
|
## Notas
|
|
|
|
- `UnitName` se asume `<name>.service`. Si la app usa otro nombre, el estado sera `not-installed`.
|
|
- La heuristica de puerto busca el primer entero en `[1024, 65535]` en `notes` o `description`. Si la app menciona varios numeros, toma el primero que encaje. Puede fallar si `notes` contiene IDs numericos antes que el puerto real.
|
|
- `UnitActive` intenta `systemctl --user is-active` primero; si el unit no se encuentra, reintenta con scope de sistema. Valores posibles: `active`, `inactive`, `failed`, `not-installed`, `unknown`.
|
|
- `PortListening` hace un dial TCP a `127.0.0.1:<Port>` con timeout 500ms. Solo aplica si `Port > 0`.
|
|
- `HostMatch` lee `~/.fn_pc` — primer linea no vacia no comentada.
