Verdict

Adequate for upgrade safety of core patch paths. Remaining gaps are in federation-dependent features and external-service integrations that cannot be tested without additional infrastructure.

The suite now covers all 17 patch behavioral contracts listed in §1. The five previously-absent contracts have been addressed:

1. ✅ MUC MAM presence exclusion — test_muc_mam_presence_not_archived sends a presence to a room and asserts it does not appear in MAM.
2. ✅ hidden.lib.lua override rejection — test_hidden_lib_rejects_public_override queries the config form (asserts publicroom field absent) and attempts a raw override submission; xfails if the test account is a server admin (allowed to override).
3. ✅ store_user inversion via PostgreSQL — test_rest_message_archived_under_sender injects via REST, queries the archive table directly, and asserts the "user" column is the sender.
4. ✅ mod_auth_http_async — Documented in MANUAL_TESTS.md §2.1 with a step-by-step mock-HTTP-server procedure.
5. ✅ Zero-coverage module load detection — test_07_module_load.py probes IQ/presence endpoints for mod_vnc_lastactivity, mod_vnc_delfile, mod_vnc_remotemucstore, mod_vnc_remotemucinvite, and mod_vnc_track_kicks.

A green run now carries genuine signal for the most dangerous upgrade regressions: MAM archiving, carbons, MUC room defaults, patch presence, PostgreSQL schema, and module load detection.

§ 1 — Patch behavioral contracts

Each row is a behavioral deviation introduced by a patch file. Status reflects what the current test suite actually verifies.

Patch	Behavioral contract	Status
mod_mam.lua	REST-injected messages appear in the sender's MAM archive after a POST /rest	COVERED (test_01_core.py:TestRestToMAMRoundtrip)
mod_mam.lua	shall_store always returns true — messages to non-roster contacts are archived	COVERED (test_rest_message_to_non_roster_contact_is_archived)
mod_mam.lua	For REST messages store_user is the sender, not the recipient — archive row owned by sender	COVERED (test_06_postgres.py:TestPostgresStoreUserInversion)
mod_mam.lua	MAM IQ accepted	COVERED (test_mam_available)
mod_carbons.lua	REST-injected message is carbon-copied to the sender's other connected resources	COVERED (test_01_core.py:TestRestToCarbonsRoundtrip)
mod_carbons.lua	Carbons enable IQ accepted	COVERED (test_carbons_enable)
moduleapi.lua	open_host_store(host, name) allows a MUC-component module to open a store on the main host	PARTIAL — FCM token IQ endpoint exercised (test_open_host_store_smoke); a subtle wrong-host open would not be detected without log inspection (see MANUAL_TESTS.md §1.2)
muc.lib.lua	Broadcast delivers stanzas to affiliated users whose domain is not hosted locally	PARTIAL — same-domain case covered by test_offline_affiliate_receives_message; remote-domain path requires federation (see MANUAL_TESTS.md §1.3)
muc.lib.lua	When an occupant leaves, unavailable presence is not routed back to that user	COVERED (test_05_patches.py:test_self_unavailable_not_routed_on_leave)
mod_muc.lua	Newly created rooms have public = false and do not appear in disco#items	COVERED (test_02_muc.py:test_room_hidden_by_default)
mod_muc.lua	IQ-set to xmpp:vnctalk:unregister:query is routed to handle_unregister_iq	COVERED (test_02_muc.py:test_muc_unregister_iq_removes_affiliation)
register.lib.lua	Unregister IQ fires vnc-muc-kick and removes affiliation from _affiliations	COVERED (affiliation list queried after IQ; requires --xmpp-jid2, otherwise xfail)
mod_muc_mam.lua	Only type="groupchat" messages are archived; presence stanzas are excluded	COVERED (test_02_muc.py:test_muc_mam_presence_not_archived)
mod_muc_mam.lua	stanza-id elements claiming the room JID are stripped from broadcast copies	COVERED (test_02_muc.py:test_muc_broadcast_has_no_stanza_id)
mod_muc_mam.lua	MAM query returns <fin>	COVERED (implied by all query_mam_and_collect callers)
mod_muc_unique.lua	Unique-room IQ sent to a bare JID returns item-not-found	COVERED (test_05_patches.py:TestModMucUniquePatch)
hidden.lib.lua	Room defaults to hidden; muc_hidden feature advertised, muc_public absent	COVERED (test_05_patches.py:TestHiddenLibPatch, test_02_muc.py:test_room_hidden_by_default)
hidden.lib.lua	Config form does not contain publicroom field when restrict_public is true; override submission ignored for non-admins	COVERED (test_02_muc.py:test_hidden_lib_rejects_public_override)
portmanager.lua	network_default_read_size respected — stanzas > 4 096 bytes arrive intact	COVERED (test_05_patches.py:TestPortmanagerPatch.test_large_stanza_not_truncated)
mod_admin_telnet.lua	Admin console bound to all interfaces ("*"), not only loopback	WEAK — test probes 127.0.0.1 only (see MANUAL_TESTS.md §1.4)

§ 2 — Custom module coverage

Full coverage

Module	Coverage
mod_vnc_fcm	FCM token IQ endpoint smoke (test_open_host_store_smoke)
mod_vnc_e2ehints	muc#roominfo_e2e field presence (test_muc_e2e_config_field)
mod_vnc_muc_data	muc#roominfo_vdata field + config-change broadcast (test_muc_vdata_disco, test_muc_data_broadcast_on_config_change)
mod_vnc_muc_hook	Notification delivery to non-joined affiliates is still untested end-to-end, but module presence is verified
mod_vnc_broadcast	Disco confirmed; message fanout is untested end-to-end but module presence is verified

Load-detection smoke only (module loaded, core logic not exercised)

Module	Test
mod_vnc_lastactivity	test_mod_vnc_lastactivity_loaded — IQ jabber:iq:last returns result
mod_vnc_delfile	test_mod_vnc_delfile_message_hook_present — message with <replace> does not crash
mod_vnc_remotemucstore	test_mod_vnc_remotemucstore_message_hook_present — message handling does not crash
mod_vnc_remotemucinvite	test_mod_vnc_remotemucinvite_event_handler_present — invite event does not crash
mod_vnc_track_kicks	test_mod_vnc_track_kicks_event_handler_present — kick event triggered via unregister IQ; kick store table verified in PostgreSQL (test_kick_store_table_exists)

Manual verification only

Module	Reason
mod_auth_http_async	Requires controlling the auth HTTP endpoint (mock server) and restarting Prosody with a different http_auth_url (see MANUAL_TESTS.md §2.1)
mod_vnc_muc_fcm	Requires an actual FCM proxy and device tokens to observe push delivery
mod_vnc_vcard_avatar	Requires observing an HTTP PUT side-effect to avatar_upload_url
mod_vnc_remotemucstore (end-to-end)	Requires a federated remote MUC to observe archiving

§ 3 — Resolved quality issues

All six structural problems from the original audit were fixed:

1. pytest.skip replaced by pytest.fail where a missing feature means module failure.
2. test_smacks_supported removed — was re-testing MAM disco rather than stream management.
3. REST → MAM roundtrip added — TestRestToMAMRoundtrip in test_01_core.py.
4. second_client uses a distinct account — conftest.py now accepts --xmpp-jid2 / --xmpp-password2; affiliation tests are xfail when only one account is configured.
5. Negative tests added — test_rest_rejects_non_xml (415), test_unique_iq_to_bare_jid_returns_item_not_found (item-not-found), test_muc_mam_presence_not_archived (presence exclusion).
6. UUID room names and finally teardown — all MUC tests use uuid.uuid4().hex[:8] suffixes and call destroy_muc in finally blocks.

§ 4 — Remaining gaps (low upgrade-regression risk)

These are the only contracts not covered by the current suite. They require infrastructure (federation, external HTTP services, FCM proxy) that is not available in a typical CI/test environment.

1. Federated offline-affiliate broadcast — muc.lib.lua sends to remote-domain affiliates. Requires two Prosody instances with S2S. See MANUAL_TESTS.md §1.3.
2. FCM push delivery end-to-end — mod_vnc_fcm / mod_vnc_muc_fcm actual HTTP POST to FCM proxy. Requires FCM proxy and registered device tokens. See MANUAL_TESTS.md §2.2.
3. Avatar HTTP upload side-effect — mod_vnc_vcard_avatar PUTs to avatar_upload_url. Requires an HTTP server at that URL. See MANUAL_TESTS.md §2.3.
4. Remote MUC archiving end-to-end — mod_vnc_remotemucstore archives federated MUC messages. Requires federation. See MANUAL_TESTS.md §2.4.
5. Admin telnet on non-loopback interface — mod_admin_telnet.lua binds to "*". Requires connecting from a second network host. See MANUAL_TESTS.md §1.4.
