# RFC-025 M4 — agent loop self-management e2e (Docker isolated).
#
# Verifies 通信龙's hard verification line: real agent-nodes prove the
# 6 self-loop tools + safety防线 cross-runtime, not just unit tests.
#
# **Critical isolation** (通信龙 红线):
#   - COMMHUB_DB=/tmp/commhub-loop-m4-$$.db (per-run isolated)
#   - test hub on :9220 (NOT 9200, NOT prod 47.x)
#   - never connects to production hub
#   - safe_rm_rf for all workdir cleanup
#
# 5 test groups × in-scope runtimes:
#   1. batch-cancel confirm-back (4th cancel in 30s → confirm_token)
#   2. cooldown real-block (edit within 30s → rejected; after 31s → ok)
#   3. multi-loop reference resolution (3 loops, edit by goal_id)
#   4. cron-lite 3 modes (interval / time_of_day / weekday)
#   5. preflight self-lock prevention (bad TZ → rejected, store unchanged)
#
# **Runtime matrix**:
#   - codex-sdk + grok-build-acp: full 5 groups via HTTP MCP path
#     (each runtime starts its own loops HTTP server in parent
#     agent-node; bearer token read from /proc/<pid>/environ — never
#     logged per 通信龙 security constraints).
#   - claude-agent-sdk: structural smoke ONLY — the 6 tools live as
#     in-process SDK MCP that only initializes inside processWithClaude
#     (per-task), so driving them requires LLM fire. Behavior防线 for
#     claude is covered by the 199-pass goals/ unit suite (cooldown,
#     batch-cancel, confirm-token, preflight all unit-tested against
#     the shared handlers). For claude we verify:
#       a. node starts + loops SDK MCP wire log line appears
#       b. addGoalFromSlash path (the LLM-free goal creation pathway)
#       c. scheduler tick observable (goal next_wake_at advances)
#
# What we deliberately DON'T assert: LLM-driven task execution after
# a wake. Single real-LLM demo run is M5 (separate, per 通信龙).

# NOTE: deliberately NOT `set -e`. We track failures explicitly via
# the PASS/FAIL counters + final exit code; set -e would silently
# abort the whole matrix the moment a single python3/grep returns
# non-zero, masking which test really failed and skipping later
# runtimes. Each helper guards its own error paths.

# Group 6: P0.3 poison-goal auto-pause — end-to-end WIRE test.
#
# Scope constraint: `GoalStore` uses an in-memory `Map` as source of
# truth (only re-loaded on process boot). External `goals.json` writes
# between MCP calls are invisible — so we cannot inject
# `consecutive_failures=5` via disk. The auto-pause TRIGGER
# (`bumpFailure` → `applyAutoPause` at scheduler-tick failure) is
# unit-tested exhaustively in `failure-counter.test.ts` (19 tests +
# 3 self-loop-tools.test.ts edit-side tests). Hitting the trigger
# end-to-end would require ≥5 real wake failures at 30s tick cadence
# = ~3 min wait, not practical for e2e.
#
# What this e2e DOES prove: after adding the P0.3 counter-reset branch
# to `handleEditMyLoop`, the existing `paused=true` → `paused=false`
# wire still round-trips correctly through HTTP MCP → handler →
# `goalStore.mutate` → `goals.json`. Basically a regression backstop
# against the P0.3 change silently breaking `edit_my_loop`'s pause
# flip on the codex/grok wire.
