"""Comprehensive hardening tests for ``muse hub``.

Coverage
--------
Unit
  - _normalise_url: scheme injection (file://, ftp://), http non-loopback rejected,
    loopback allowed, scheme-less normalised to https, trailing slash stripped
  - _hub_hostname: standard URL, URL with port, URL with path, bare hostname
  - _ping_hub: reachable, HTTP error, URLError, timeout, redirect refused
  - _hub_api: file:// scheme blocked, response size cap, error detail sanitized,
    missing token exits, None-value payload keys stripped
  - _resolve_proposal_id: full UUID passthrough, prefix match, no match, ambiguous match
  - _format_proposal: all fields sanitized

Integration (CliRunner + mock hub)
  - run_connect: --json schema, re-connect warns, normalisation, invalid scheme exits
  - run_disconnect: --json ok, --json nothing_to_do, text mode to stderr
  - run_status: --json all keys present, no-hub exits, not-authenticated exits
  - run_ping: --json ok, --json error, text mode to stderr, unreachable exits nonzero
  - run_proposal_list: --json is a JSON array, text mode to stderr, no-proposals message
  - run_proposal_create: --json schema, missing branch exits, sanitizes output
  - run_proposal_merge: --json schema, merge=false exits nonzero
  - run_proposal_show: --json passthrough

Security
  - file:// hub URL blocked in _hub_api before network
  - ANSI in proposal title/branch sanitized in _format_proposal
  - ANSI in proposal ID sanitized in _resolve_proposal_id errors
  - hub URL in errors sanitized in _get_hub_and_identity
  - Response body size cap prevents OOM

E2E (via CliRunner)
  - connect --json schema includes all required keys
  - disconnect --json schema correct for both ok and nothing_to_do
  - ping --json schema with all required keys
  - status --json all keys always present (no missing keys when not authenticated)

Stress
  - 8 concurrent ping checks against isolated mock responses
