# web modem/protocol tests — pure Node, no browser or second device needed
test-web:
	@node test/web-protocol.test.js

# zebra-spaces state-machine tests — pure unit tests for the FSM framework
# + each machine spec (publish / subscribe / call / remote-tile). Extracts
# the live code from web/zebra-spaces.html so the tests track the page.
test-fsm:
	@node test/zebra-fsm.test.js

# Receive-side stream lifecycle (watchVideoTrackForRemoval) — fake-clock
# state-machine tests covering 'when is it safe to remove a tile'. Catches
# the regressions where transient mutes (NACK gaps, network blips, mobile
# handoffs, hard-refresh renegotiation churn) would otherwise kill live
# tiles. Extracts the function from the page and the shipped mute window
# so the assertions track what's live.
test-video-removal:
	@node test/video-track-removal.test.js

# Mesh state-sync invariant tests — pins the contract fox stated as
# "whatever one device shares all should see, and when unshared none
# should see." Runs the shipped handleRemoteSfuTrack + renderVideoTile +
# removeVideoTile + watchVideoTrackForRemoval against multi-peer
# scenarios with synthetic ontrack/mute/unmute/ended events. Catches
# regressions where one peer's publish/unpublish leaves another peer
# out of sync.
test-mesh:
	@node test/multi-peer-mesh.test.js

# Mod-action serializer — pins the kick race fix fox hit 2026-06-04
# ("kicked two phones, only one was kicked"). Extracts runModSerial +
# awaitStateUpdate + resolvePendingStateUpdate from the live page so
# the assertions track the shipped code, then drives synthetic mod
# actions through them with a stubbed roomEpoch counter to prove the
# second action signs against the FRESH epoch.
test-mod-actions:
	@node test/mod-action-serializer.test.js

# SelfListenerFSM — pins the state-machine contract for the speaker/
# cohost/host "switch myself to the buffered HTTP listener stream"
# toggle. Extracts createFSM + selfListenerSpec from the live page so
# the spec can't drift from shipped transitions (off↔on with
# TOGGLE/ENABLE/DISABLE/UNMUTE/DEMOTED/CLEAR edges).
test-self-listener:
	@node test/self-listener-fsm.test.js

# Listener audio attach pipeline — pins src→(jbuf)→gain→destination
# graph reachability through attachAudioStreamViaWorklet,
# setWorkletStream, installJitterBuffer, attachSfuTrack,
# flushSfuStreams. Extracts each function from the live page and
# replays the cascade scenarios (fresh attach, same-stream no-op,
# different-stream in-place swap, dedup by pubkey, publisher rejoin,
# zero-live-track reject). Catches silent-listener regressions where
# a chain builds but never reaches audioCtx.destination.
test-listener-audio:
	@node test/listener-audio-attach.test.js

# zebra-spaces JS↔Go protocol parity + vault + ed25519 + (optionally) a live
# server flow. The live-server tier auto-runs when proxy.unturf.com sits
# alongside this checkout AND has a Go toolchain — we build the relay binary
# transparently and point the test at it. Otherwise that tier is skipped and
# only the pure-protocol/crypto tiers run.
