"""End-to-end integration test: ClankerSaddle web app + saddle daemon.

Drives the web app the way statum.js does (entrypoint state loads plus
action POSTs carrying the auth slot and sealed private blobs) while a
REAL saddle daemon runs a REAL goal against a real git checkout under
WORKSPACE, powered by saddle/test/mock_llm.py with a deterministic
script — both binaries, the true cross-binary contract proof (the
per-repo fake-peer suits live in web_stack_test.py / saddle e2e).

The consolidated goal-era arc (plan 15, re-baselined for C+D):
1. goal create -> start: the goal-run assignment reaches the daemon
   over the ask/allocate channel with the full plan-12 payload (kind/
   mode/creator/goal context/ephemeral branches for workers)
2. a commentary-only round and a trailing-comment round feed VERBATIM
   (comment-policy-free inputs, plan 15 D1) before the pre-plan
   question block -> answered on the goal page -> the ONE answer
   resolves the goal-run task's single task_blocks row and the parked
   goal agent resumes with the verdict wording
3. plan submit -> reject-with-feedback -> revision -> approval (the
   agreed verdict words ride the resume)
4. task fan-out through the real /api/saddle/task/create + enqueue
   callbacks; the worker's DEGENERATE first response is
   validator-caught (plan 15 D2 — never executed, one receipt, the
   session continues); the clean resend runs in its ephemeral
   worktree branch cut from the goal clone, commits, completes —
   worktree auto-pruned, branch kept
5. the terminal transition (the goals row's last_terminal_watermark,
   plan 15 C3 — goal_events is gone) coalesces (~SADDLE_GOAL_RESUME_S)
   into the goal agent's batched resume; it merges, deletes the task
   branch, pushes the goal branch (push-before-review) and submits
   the completion report
6. completion review accept — the live per-repo push flags gate it
   (plan 15 C4): the accept REFUSES while origin is behind, passes
   once the branch is re-pushed and the probe re-cached -> goal
   complete, run task done
7. the goal agent's terminal sessions (SSE replay), the audit trail
   (the DERIVED goal narrative, typed session_commands, the
   harness-authored system rows), the /status goal_branches cache
   sampled by the manual saddle refresh
8. the legacy ingest API surface (401s, typed updates, exactly-once
   poll handover) and the stm-markdown renderer

Prerequisites (see README.md "Integration testing"): the web app
running with SPRY_SEED_ADMIN_USERNAME=admin,
SPRY_SEED_ADMIN_PASSWORD=adminpass123, SADDLE_LLM_BASE_URL pointing
at the mock, SADDLE_PROJECTS_ROOT=$WORKSPACE and a FRESH database
(the harness asserts an empty tasks/goals state); a saddle daemon
with SADDLE_WORKSPACE_ROOT=$WORKSPACE (the shared-volume deployment
assumption — the goal clone anchors the worker worktrees); a git
repo with at least two commits at $WORKSPACE/demo whose origin is
pushable (the harness prepares demo + demo-origin.git when WORKSPACE
is empty).

Environment:
  WEB            web app base URL      (default http://localhost:8080)
  SADDLE         daemon control URL    (default http://localhost:7100)
  SADDLE_HOST    host:port to register (default localhost:7100)
  SADDLE_NAME    registration name     (default saddle-e2e-1)
  WORKSPACE      demo repo parent dir  (default /tmp/clanker-e2e/workspace)
  DB_PATH        web app SQLite file   (for audit assertions)
  MOCK           mock_llm.py path      (default <repo>/../saddle/test/mock_llm.py)
  MOCK_PORT      local mock port       (default 9999)
  MOCK_CMD       run instead of the local mock (e.g. a podman exec line
                 that starts the mock inside the saddle container); the
                 script skips spawning the mock when set (the mock then
                 needs its own --capture for the receipt assertions)

Prints PASS/FAIL lines Statum-style; exits non-zero on any failure.
