概述

完整实现 Moss CI —— 面向 Moss 智能体的多维度回归评测平台。涵盖数据模型、YAML 解析、Pipeline 引擎、Moss Runner(CLI/API/SDK 三后端)、5 种评估器、持久化存储、FastAPI 服务、CLI、Flake 检测、回归分析、React Dashboard,以及从 mock 到真实 Moss 的切换。

本 PR 一次性落地实现计划的全部 16 个 Task / 8 个 Phase,测试 68 passed

架构

分层架构:Pydantic 数据模型 → YAML 解析 → Pipeline 引擎(DAG 调度 + 并行执行)→ Moss Runner → Evaluator → FastAPI + CLI + React Dashboard。PostgreSQL 存元数据(开发用 SQLite),MinIO 存日志/产物,Redis 做队列和缓存。

技术栈:Python 3.11+ / Pydantic v2 / FastAPI / Typer / SQLAlchemy async / asyncpg / Redis / MinIO / PyYAML / NetworkX / Structlog / Tenacity / SSE-starlette / React + TypeScript + Recharts + Vite

过程中处理的实现计划缺陷

实现计划(spec)自身的测试与实现代码有若干对不上之处,已逐一修正:

  1. Task 5 — CLIBackend shell 拆分:exec 模式下 bash -c 'echo $X' 被当成单个 argv,测试挂。改用 shlex.split(prompt) 拆分。
  2. Task 6 — API 后端测试 mockpatch(return_value=AsyncMock) 对异步方法返回非 awaitable;AsyncMock.json() 返回 coroutine。改用 MagicMock response(.json() 同步)+ AsyncMock post。
  3. Task 8 — Repository 关系懒加载:async session 下 get/list 访问嵌套关系触发 lazy load 崩(MissingGreenlet)。加 selectinload 链式预加载 suites→tests→evals。
  4. Task 9 — Cache TTLttl=-1set 里被 else 0 压成「永不过期」。重写 expiry 逻辑:>0 未来、==0 永不、<0 已过期。
  5. Task 13 — Flake 状态语义:实现把「达阈值但非全过」判为 flake,测试期望 pass。保留 flake 状态(区分不稳定通过),修正测试期望为 flake
  6. Task 16 — API 层 async repo_repo() 为 async 但调用处未 await。统一为 repo = await _repo()
  7. Task 16 — Executor fail_fast_execute_suite 的 fail_fast 遍历裸 coroutine 调 .done() 崩(Task 4 遗留,被真实 Moss 失败路径暴露)。用 asyncio.Task + asyncio.wait(return_when=FIRST_COMPLETED) 重写,实现真正的 fail_fast 取消。
  8. Task 16 — DB 初始化:httpx ASGITransport(测试)不触发 FastAPI lifespan,DB 不初始化。Database.init() 改为幂等,_repo() 兜底 ensure。

已知待办(计划内明确推迟)

以下功能在实现计划「Scope Notes」中标注为有意推迟,留作后续 spec:

  • 模板变量({{ model }} 替换)、suite 继承、条件执行、matrix 策略
  • OAuth2/OIDC + Webhook + 定时触发(API 暂无 auth)
  • Dashboard 的 flake 状态单独展示

端到端冒烟(需配环境)

Task 16 Step 10 的真实 Moss 冒烟需运行环境提供 Moss 后端之一 + judge 端点:

# 选其一
#   CLI:  set MOSS_CLI_COMMAND=moss
#   API:  set MOSS_API_URL=https://...
#   SDK:  import moss 可用
# Judge:

- CLIBackend now tokenizes moss_command, so MOSS_CLI_COMMAND can point
  at an interpreter + script (e.g. 'node /abs/cli.js --config-file ...')
  not just a PATH-resolved binary.
- CLI `run` now invokes a real MossRunner by default; add --mock to keep
  scaffold ([mock]) behavior when no Moss instance is available.
- Add examples/moss_smoke.yaml: 4-test smoke suite (contains evals) used
  to verify the real Moss end-to-end path (Task 16 Step 10).

Verified against a real Moss CLI: 4 passed, 0 failed via
  MOSS_CLI_COMMAND='node .../dist/cli.js --config-file .../config.json'
  moss-ci run examples/moss_smoke.yaml --no-fail-fast

Moss writes session logs (.moss/sessions/*.jsonl) into the cwd when
invoked. These are runtime artifacts (and were accidentally committed
in the previous commit). Add .moss/ to .gitignore and remove them from
the tree.

- examples/moss_capabilities.yaml: a real-value test suite where every
  contains target is something Moss can only answer by actually invoking
  tools or reasoning — e.g. a random token (ZETA-7741-NOVA) planted in
  examples/fixtures/secret_config.json that Moss must read_file to know.
  Covers: file-read+extract, code-bug detection (regex, case-insensitive),
  multi-step counting, and a flake-detection stability test.
- Fix infinite recursion in flake detection: FlakeDetector.detect called
  executor._execute_test, which re-entered the flake branch for the same
  plan. Split _execute_test into a flake gate + _run_test_once (single
  non-flake run); FlakeDetector now calls _run_test_once so re-runs don't
  recurse.
- Verified end-to-end against real Moss: 5 passed, 0 failed (4 read/tool
  tests + 1 stability test run 3x, all pass).

- `run` now persists each PipelineResult to the RunRepository (SQLite by
  default) and prints the run_id, so a run is comparable later.
- `history` lists persisted runs (id, pipeline, status, summary).
- `status <run_id>` shows per-test pass/fail for a run.
- `diff <prev> <curr>` runs DiffEngine.compare and prints new_failures /
  fixed / improved / degraded — the core CI value: not "did it pass" but
  "did it regress since last run".
- `logs <run_id>` shows stored Moss output per test.

Previously these commands were scaffold stubs ("not available — API not
running"). The CLI is now a usable local CI: run → diff → catch regressions.

Co-Authored-By: Claude <noreply@anthropic.com>
A reference workflow for Moss forks (D-Robotics/moss): on push/PR, install
moss-ci from 1-ztc/ci_test, build Moss, and run the capability suite
(moss_capabilities.yaml) against the freshly-built Moss. Fails the PR if
a capability regresses.

Key mechanics, validated locally:
- moss-ci ships the CLI but not the example suites, so the workflow also
  fetches the examples/ tree from the same ref and stages it into the
  checkout (the suite uses workdir: ./examples/fixtures, resolved against
  the moss-ci cwd = the Moss checkout root).
- Moss ignores env vars for model settings, so a temporary config.json is
  written at runtime from the MOSS_API_KEY repo secret; the file lives only
  on the one-shot runner.

To activate in a Moss fork: copy this file to
<moss-fork>/.github/workflows/moss-ci.yml and add the MOSS_API_KEY secret.

Note: this gates on pass/fail. Cross-run regression DIFF (new_failure/fixed)
needs a shared result store across runners — a follow-up.

shlex.split() with posix=True (the default) eats backslashes as shell
escapes: 'C:\Users\tongchun.zhao\...\config.json' becomes
'C:Userstongchun.zhao...config.json', so Moss can't read --config-file
and exits 3 with "needs a model configuration".

Use posix=False on Windows (os.name == 'nt') for the command-prefix split
so Windows paths survive. Forward-slash paths (Linux CI runners) were
already fine; this fixes local Windows runs. Prompt tokenization is
unchanged (still posix=True) so the bash -c test stays green.

CI failed with "ModuleNotFoundError: No module named 'aiosqlite'" because
aiosqlite was only in the dev extras — the CLI's run/history/status/diff
persist to SQLite at runtime, so it must be a runtime dependency. Move it
to [project].dependencies.

Also collapse the CLI `run` command's two asyncio.run() calls (run tests,
then save) into one async function. The second asyncio.run() raised
"cannot be called from a running event loop" on some platforms and left a
stale loop; a single run_and_save fixes it. Persistence is wrapped in
try/except so a DB hiccup never masks the actual test results.

Co-Authored-By: Claude <noreply@anthropic.com>
The CLI now lets a run result travel outside the SQLite DB so CI can
diff consecutive runs (the core CI value: not "did it pass" but "did it
regress since last run").

CLI:
- `moss-ci export [run_id] -o <file.json>` — write a run (or the latest
  run if run_id omitted) to JSON. Omit run_id is for CI where the id
  isn't easily captured.
- `moss-ci diff-files <prev.json> <curr.json>` — read two exported runs
  and report new_failures/fixed/improved/degraded.
- Refactored the DB-backed `diff` command's print into `_print_diff`,
  shared with `diff-files` so both produce identical output.

CI workflow (reference at .github/workflows/moss-ci.yml, copied to the
Moss fork): after running the capability suite, restore the last run's
JSON from a per-branch cache, export the current run, `diff-files` the
two into $GITHUB_STEP_SUMMARY (visible on the PR Checks tab), then cache
the current run as next run's baseline. First run on a branch establishes
a baseline; subsequent runs report the regression diff.

Verified end-to-end locally: baseline (5 pass) → tightened eval (1 fail)
reports "1 new failure"; reversing reports "1 fixed".

…ce/tool_args

The tool_sequence and tool_args evaluators were untested against real Moss
because CLIBackend only captured stdout text — moss_result.tool_calls was
always empty. Now CLIBackend reads Moss's session jsonl (the one Moss writes
to <cwd>/.moss/sessions/ per invocation) and extracts Anthropic-style
tool_use blocks, converting {"name","input"} to moss-ci's {"tool","args"}.

Snapshot existing sessions before the run, then parse only the NEW session
file(s) so stale tool-call history can't leak into the current run's
result. Robust to missing/empty/malformed sessions (returns []).

moss_capabilities.yaml gains a "工具调用-顺序与参数" test using
tool_sequence (read_file, strict) + tool_args (path contains secret_config),
verified passing against real Moss: Moss called read_file with
path=secret_config.json and both evaluators passed.

Covers: quickstart (env vars + run + diff), CI activation in a Moss fork,
cross-run regression diff via cache, custom Anthropic-protocol endpoints
(e.g. horizon — needs the Bearer-auth support in moss fork 2026_07_08),
the 5 evaluators, tool-call extraction from Moss sessions, and how to
write capability tests that Moss can only pass by actually working.

No secrets — key handling points at GitHub Secrets / local files only.

The extract-token/field prompts previously contained the expected answer
in the prompt text itself, so Moss could pass by echoing the prompt
without actually reading the file — masking real read_file regressions.
Reword prompts to ask for the field VALUE without revealing it, so Moss
must truly read_file to answer. (Used to verify a real read_file
regression is caught — see moss fork 2026_07_08.)

Upgrade the capability suite from 6 baseline tests to a 13-test matrix
covering Moss's core agent capabilities, split into CI-cost-controlled
layers.

CLIBackend (moss_ci/runner/cli_backend.py):
- Extract files_modified from the Moss session (write_file/edit_file/
  apply_patch/move_file tool_use input.path) → MossResult.files_modified,
  so the side_effect evaluator (file_modified) works against real Moss.
- Insert `--` before the prompt argv so prompt text like "python -m pytest"
  isn't parsed as Moss flags (-m → --model → HTTP 400). env-injection
  test rewritten to a fixture script (bash -c no longer viable with --).

CLI (moss_ci/cli/main.py):
- `run --tag <tag>` filters tests by TestConfig.tags, enabling layer split:
  push/PR runs `--tag quick`, manual/nightly runs the full layer.

Suite (examples/moss_capabilities.yaml, v2.0): 13 tests across
A. tool calls (read/write/multi-step sequence + tool_args)
B. file side effects (write/modify, side_effect file_modified)
C. multi-step end-to-end (autonomous bug-fix via task:, tests_pass)
D. code understanding (division-by-zero, empty-list, count)
E. stability (flake_detection runs=3 on key tests)
F. quality (llm_judge code review)
Fixtures: buggy.py + test_buggy.py (C1), to_transform.txt (C2).

Workflow (.github/workflows/moss-ci.yml): two layers — quick on push/PR,
full on workflow_dispatch + nightly schedule; per-layer cache keys so
diffs compare within the same layer; MOSS_CI_JUDGE_API_URL secret wired
into the run step.

Verified locally: quick layer (9 tests) all pass against real Moss
(deepseek-v4-pro); files_modified + side_effect confirmed; tool_sequence
strict ordering confirmed. C1 end-to-end depends on Moss autonomous
maxTurns config (full layer, manual/nightly).

…-insensitive)

C1 (autonomous bug-fix) was failing even when Moss fixed the bug and ran
the tests, because tests_pass checked for the exact uppercase pytest
banner "PASSED"/"OK" — but Moss reports results in natural language
("All 4 tests pass", "tests passed"). Match "pass" case-insensitively
(covers pass/passed/passing). Drop the bare "ok" match — it's a substring
of "broken" and caused false positives. tests_fail similarly matches
"fail"/"error" case-insensitively.

This was the real blocker for the C1 end-to-end test, not maxTurns (Moss
completes the fix in ~5 tool calls, well under the 64-turn default).
Verified: Moss reads buggy.py → edits it → runs pytest → reports "All 4
tests pass" → tests_pass eval now passes.

Rewrite the capability-suite section for v2.0: 13 tests across 6
dimensions split into quick (push/PR) and full (manual/nightly) layers,
all 5 evaluators in use, tool_calls + files_modified extraction, and the
local end-to-end verification result (quick 9 pass, full 4 pass incl.
C1 autonomous bug-fix 3/3). Records the C1 fix (tests_pass case-insensitive,
maxTurns wasn't the blocker) and adds guidance on writing tests
(answer-source-proof prompts, tags, flake_detection).

The llm_judge evaluator was inert: it returned a fake score 3.0 when no
endpoint was configured (F1 always "passed") and called an OpenAI
/chat/completions shape that didn't match the real endpoint.

- Rewrite _call_judge for Anthropic /v1/messages + Bearer auth, reading
  MOSS_CI_JUDGE_API_URL + MOSS_CI_JUDGE_API_KEY from env. Host-based auth
  detection mirrors the Moss fork: Bearer for non-anthropic gateways
  (horizon at llmapi.horizon.auto), x-api-key for api.anthropic.com.
- Unconfigured judge now marks the eval error (score=None) instead of
  faking 3.0 — no silent pass, no phantom score polluting the diff engine.
- Robust score parsing: strip ```json fences, JSON, then regex fallback for
  prose like "score is 4".
- Fix dimension threshold bug: min==0 (default) dimensions are recorded
  but don't gate pass, instead of letting any score through.
- Default judge_model -> HORIZON-GLM; F1/llm_judge.yaml updated.
- Add 8 real tests (success/fence/prose/http-error/bearer/apikey/dim).

Co-Authored-By: Claude <noreply@anthropic.com>
Three independent bugs found while wiring up judge end-to-end:

- flake_runs were never persisted (RunRepository skipped the field), so
  `status`/`logs` showed "flake" with no per-run breakdown. Add a JSON
  column + serialize/deserialize + a lightweight ALTER TABLE migration so
  existing dev DBs get the column.
- CLI --concurrency defaulted to 10, ignoring each suite's YAML
  max_concurrency. The inner per-suite semaphore masked it, but the
  semantics were muddled and fragile. Default is now None (no global cap);
  the suite's own max_concurrency is the real limit, --concurrency N caps it.
- Moss wrote into the source fixtures dir (hello.txt etc. residue), so the
  next run's create-file test saw the file exist and skipped -> failed.
  Executor now stages a throwaway copy of workdir per run (ignoring
  .moss/__pycache__), so source fixtures stay clean across runs.
- logs/status now render flake per-run verdicts (+ judge score) since the
  data is finally available.

Co-Authored-By: Claude <noreply@anthropic.com>
`moss-ci run` exits 1 when tests fail, which skipped the Export/diff
steps — so the regression-diff report (CI's core value) never ran exactly
when tests failed, and the baseline cache got corrupted copying a missing
file. Add if: always() to Restore/Export/diff; guard Save with || true and
emit a has_baseline flag; cache only when a baseline exists.

Also inject MOSS_CI_JUDGE_API_KEY (URL already wired) so F1 can really
score on CI. Update USAGE/PROJECT_STATE: judge now uses Anthropic protocol
+ Bearer at https://llmapi.horizon.auto (HORIZON-GLM); unconfigured = error,
not fake 3.0.

Co-Authored-By: Claude <noreply@anthropic.com>
On CI the GitHub runner can't reach llmapi.horizon.auto (ConnectTimeout
— Chinese IP, runner is US-west), so F1's judge failed and blocked the
PR behind branch protection. The judge code is correct (scores 5.0 when
reachable), so failing the whole suite on a network gap was wrong.

- Distinguish an unreachable endpoint (network) from a real error. A
  network failure (httpx TransportError/ConnectTimeout/etc) now SKIPS the
  eval — it's environmental, auto-recovers when reachable. Config missing
  / HTTP 401 / unparseable score still hard-fail (never fake a pass).
- EvalResult.skipped flag; executor excludes skipped evals from the pass
  verdict (all-skipped -> test "skipped"); flake detector treats an
  all-skipped set as skipped.
- Short connect timeout (10s) so an unreachable host fails fast instead
  of burning 120s × 3 flake runs.
- Readable error: httpx ConnectTimeout has empty str(), so lead with the
  type name instead of an unreadable error="".
- Persist skipped (in details JSON, no new migration).
- status/logs render skipped judge runs with the reason.

Local (reachable) still scores 5.0/3; CI (unreachable) will skip F1 and
the suite stays green. Swap in a public-reachable endpoint to re-enable.

Aligns moss-ci with the upstream Moss repo (D-Robotics/moss, MIT) so the
tool can live alongside or within the organization without a license
ambiguity blocking compliance review. Without an explicit license the
code defaulted to all-rights-reserved.

Co-Authored-By: Claude <noreply@anthropic.com>
The tool and test suites now live at D-Robotics/moss-ci (main), so the
upstream Moss CI no longer depends on a personal fork (1-ztc/ci_test).
Updates the workflow's pip install + git clone sources and the docs to
match. Branch ref changes from feat/implementation to main.

The current.json (per-test moss_output + moss_tool_calls) was only
written to the runner's /tmp and lost when the job ended, leaving no
way to see what Moss actually returned when tests fail. Upload it as a
short-lived artifact so failures can be diagnosed without re-running.
Marked with a comment so it can be removed once the suite is green.

Co-Authored-By: Claude <noreply@anthropic.com>
When tests come back with empty moss_output, this pinpoints the failing
layer: L1 TCP reachability to the gateway, and L2 an authenticated
/v1/chat/completions call (HTTP status only). Key read from env, never
echoed. Distinguishes network-blocked (GitHub IP not allowlisted) from
auth/path errors. Remove once the suite is green.

Co-Authored-By: Claude <noreply@anthropic.com>
F1's llm_judge eval keeps timing out from the runner. Add a parallel
L1 (TCP) + L2 (authenticated /v1/messages, host-based Bearer/x-api-key)
probe for MOSS_CI_JUDGE_API_URL so we can see whether it's network
blocked (GitHub IP not allowlisted) vs auth/path. Key never echoed.

Co-Authored-By: Claude <noreply@anthropic.com>
The llm_judge (F1) eval skips cleanly when its endpoint is unreachable
from the runner (internal/VPC gateway GitHub hosted runners can't
reach) — it's not an error and doesn't turn CI red. Two clarity fixes:

- Update the secret comment to say "skipped, not error" instead of the
  old "marked error" wording, and note unreachable endpoints auto-recover.
- In the job summary, detect skipped llm_judge evals in the export and
  print a one-line "llm_judge skipped" note with the reason, so it's
  visible in PR Checks instead of buried in step logs.

No behavior change to pass/fail — F1 still skips, just no longer a
mystery to anyone reading the CI output.
