# Wave-1 integration smoke test
#
# Assertion-driven LIVE coverage of the full wg stack — this MUST run live
# against real endpoints; no stubs, no mocks, no special bypass. If the
# default config is broken, this smoke fails. The earlier version of this
# script silently passed because it relied on a fake LLM and ran the daemon
# with --no-coordinator-agent — that's exactly how the wg-nex 404 slipped
# through and the user hit it on the first 'hi' in TUI chat.
#
# Scenarios (live unless explicitly noted):
#   1. Claude task graph (init + daemon + phantom check + task lifecycle)
#   2. Nex two-turn (fake LLM) — kept as offline lower bound
#   3. Setup routes (claude-cli + openrouter non-interactive)
#   4. Launcher history recall in TUI
#   5. Model alias resolution (claude:sonnet → current model id)
#   6. **Nex live**: wg init -e https://lambda01… -x nex; wg service start;
#      wg chat 'hi' must return a non-error response within 30s; 4 more
#      messages back-to-back must all succeed. If lambda01 is unreachable
#      a LOUD banner is printed (NEX SMOKE SKIPPED — endpoint unreachable);
#      it is greppable in run output. Set WG_SMOKE_FAIL_ON_SKIP=1 to make
#      that condition exit non-zero instead.
#   7. **Claude live chat**: wg init -x claude; wg service start; wg chat
#      'hi' must return a non-error coordinator response within 60s.
#
# Configure via env vars:
#   WG_LIVE_NEX_ENDPOINT  default https://lambda01.tail334fe6.ts.net:30000
#   WG_LIVE_NEX_MODEL     default qwen3-coder
#   WG_SMOKE_FAIL_ON_SKIP if set to 1, treat loud-skip as fail (CI strict mode)
#   WG_SMOKE_KEEP_SCRATCH if set to 1, do not remove scratch dirs (post-mortem)
#
# Usage:
#   bash scripts/smoke/wave-1-smoke.sh            # run all (live + offline)
#   bash scripts/smoke/wave-1-smoke.sh --quick    # skip slow scenarios (2,4,6,7)
#   bash scripts/smoke/wave-1-smoke.sh --offline  # skip live scenarios (6,7)
#
# Run before merging any wave-1 task and any task touching coordinator/nex.

# coordinator-0 with task .chat-0", so a fresh `wg init` (which has no
# `.chat-0` task) sent `wg spawn-task .chat-0` into a perpetual restart
# loop chasing a phantom. The fix: enumerate `.chat-N` (and legacy
# `.coordinator-N`) tasks from the graph; spawn one supervisor per task;
# subprocess loop pre-flight checks task existence and exits cleanly on
# orphan instead of restart-looping.
#
# Verification: run the regression test suite directly. These tests are
# fast (pure-function + 3 short-running daemon subprocesses) and will
# fail if anyone reverts the orphan-guard logic.

# ── Scenario 6: Nex live against user's real endpoint ─────────────
#
# This is the scenario the previous wave-1 smoke FAILED to cover. The
# user's literal reproduction:
#   $ wg init -m qwen3-coder -e https://lambda01...:30000 -x nex
#   $ wg service start
#   $ <open chat in TUI, type 'hi'>
#   → 'why isn't the smoke test catching all this stuff! i did the most
#      basic thing i wrote hi and then it barfed.'
#
# The bug was in the named-endpoint path of create_provider_ext: the
# stored endpoint URL had no /v1 suffix, so the OAI client posted to
# /chat/completions and got 404. The coordinator-spawned `wg nex`
# (which does NOT use -e) hit this path, which meant the inline-URL
# fix in agent-62 was insufficient and only the agent-72 fix caught
# the named-endpoint case.
#
# This smoke runs the full TUI chat flow programmatically. `wg chat
# 'hi'` is exactly what the TUI Send button does — it goes through
# IPC UserChat to the coordinator, which proxies to the nex agent via
# chat/<coordinator-ref>/{inbox,outbox}.jsonl.
