1	"""Comprehensive hardening tests for ``muse hub``.
2
3	Coverage
4	--------
5	Unit
6	- _normalise_url: scheme injection (file://, ftp://), http non-loopback rejected,
7	loopback allowed, scheme-less normalised to https, trailing slash stripped
8	- _hub_hostname: standard URL, URL with port, URL with path, bare hostname
9	- _ping_hub: reachable, HTTP error, URLError, timeout, redirect refused
10	- _hub_api: file:// scheme blocked, response size cap, error detail sanitized,
11	missing token exits, None-value payload keys stripped
12	- _resolve_proposal_id: full UUID passthrough, prefix match, no match, ambiguous match
13	- _format_proposal: all fields sanitized
14
15	Integration (CliRunner + mock hub)
16	- run_connect: --json schema, re-connect warns, normalisation, invalid scheme exits
17	- run_disconnect: --json ok, --json nothing_to_do, text mode to stderr
18	- run_status: --json all keys present, no-hub exits, not-authenticated exits
19	- run_ping: --json ok, --json error, text mode to stderr, unreachable exits nonzero
20	- run_proposal_list: --json is a JSON array, text mode to stderr, no-proposals message
21	- run_proposal_create: --json schema, missing branch exits, sanitizes output
22	- run_proposal_merge: --json schema, merge=false exits nonzero
23	- run_proposal_show: --json passthrough
24
25	Security
26	- file:// hub URL blocked in _hub_api before network
27	- ANSI in proposal title/branch sanitized in _format_proposal
28	- ANSI in proposal ID sanitized in _resolve_proposal_id errors
29	- hub URL in errors sanitized in _get_hub_and_identity
30	- Response body size cap prevents OOM
31
32	E2E (via CliRunner)
33	- connect --json schema includes all required keys
34	- disconnect --json schema correct for both ok and nothing_to_do
35	- ping --json schema with all required keys
36	- status --json all keys always present (no missing keys when not authenticated)
37
38	Stress
39	- 8 concurrent ping checks against isolated mock responses
