From a06a6fed7e66b763a3d769f2886e28201c0b4d31 Mon Sep 17 00:00:00 2001 From: Zeren Wang <53075619+Vanzeren@users.noreply.github.com> Date: Tue, 1 Sep 2026 10:13:41 +0200 Subject: [PATCH] feat(harness): deterministic acceptance checklist for subagent delegations (RFC #4651, layer 2) (#5109) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit * feat(harness): deterministic acceptance checklist for subagent delegations (RFC #4651, layer 2) PR4 of RFC #4651: check lead-supplied acceptance_criteria in code when a subagent completes, so objectively checkable requirements can never be silently passed by a self-report. - subagents/acceptance_checks.py: deterministic leaf families — file: exists|non-empty and file_written: read through read_current_file_content scoped to the shared thread workspace; the read uses the sandbox-native virtual path form (the local read validator and provider mount tables resolve /mnt/user-data/... paths, not host paths); the scope decision canonicalizes with realpath on the local sandbox so workspace symlinks cannot escape into uploads; a remote provider's "Error: ..." return string is normalized to a failed check (provider-typed via is_local_sandbox); a UnicodeDecodeError marks a binary deliverable as existing and non-empty; out-of-scope paths degrade to UNVERIFIED. tests_passed: anchors to a matching recorded bash execution with status=success and a test-summary shape; matching is shell-structure aware with control-flow attribution (span must end at the last segment with provable execution), negating-option values are ineligible evidence and a target negated anywhere in the command degrades the match, extra flags must be selection-preserving, extra positionals widen only after a path-scoped criterion, truncated commands degrade via command_truncated, the summary shape is read only from output attributable to the matched segment (preceding segments provably silent by invocation form), and pass shapes require a nonzero passed count. Criterion text is neutralized with neutralize_untrusted_tags before storage/rendering. Anything else renders UNVERIFIED, never silently passed. - executor: accumulate bounded bash command/output evidence per streamed chunk (merged by tool_call_id, newest-capped) so subagent summarization compacting earlier messages cannot erase a recorded execution; the recorded status is the actual shell exit status parsed from the output's exit marker (signed codes included; the remote Command exited with code N form is accepted only as the whole trimmed output), falling back to deerflow_tool_meta only when no marker exists. - sandbox providers: e2b/opensandbox/tenki/boxlite append the LocalSandbox-style "Exit Code: N" marker on nonzero exit even with non-empty output; aio propagates the SDK's structured exit_code on both exec paths the same way; local timeouts append Exit Code: 124; and _truncate_bash_output always preserves a trailing exit marker (signed included) inside its budget, with a 32-char floor raising any smaller configured limit, so the actual shell outcome always survives in the output text. - task_tool: run the checklist offloaded (asyncio.to_thread) on the completed branch, failure-isolated; stamp the verdict into result metadata and render the per-criterion section into the model-visible result text. - status contract: additive subagent_acceptance_verdict transport with read-side structural validation. - delegation ledger: entry carries the verdict and renders a compact acceptance segment; gateway strips caller-forged verdicts from both ledger entries and message metadata, like the citation verdict. - blocking-IO anchor pins the offload (teeth proven red->green); leaf read errors catch only OSError/SandboxError so unexpected errors reach the task-tool-level isolation instead of being mislabeled. * fix(harness): close acceptance evidence gaps from review (RFC #4651 PR4) - negating options: overlap with a matched criterion target is now checked by path/nodeid prefix, not exact token equality — excluding a sub-path of the criterion's selection (pytest tests --deselect tests/unit/test_auth.py) degrades to UNVERIFIED instead of holds - output attribution: any redirection token in the matched final segment makes the recorded tail non-attributable (> / >> / 2> are word characters to the parser, so redirection was invisible to the matcher) - silent-source allowlist narrowed from any *activate suffix to the */bin/activate shape - status_contract docstring: restore the shared-fixture sentence and note subagent_acceptance_verdict is deliberately outside the fixture - executor: update_bash_executions publishes [] (stream carried no bash-family calls) instead of collapsing it into None, mirroring update_tool_receipts * fix(harness): close acceptance residual gaps from re-review (RFC #4651 PR4) - tests_passed: add error outcomes to the fail shapes — "4 passed, 1 error" and pytest's "ERROR " short summary no longer satisfy the pass shape when the exit status is swallowed (|| true) or absent; zero-error counts stay clean. - file leaves: bound the deliverable read — a "wc -c" shell size probe answers files above 50k bytes without loading ~2x their size, honoring the host-bash kill switch and falling back to the full read on any non-integer rendering, so verdicts never get less sound. - executor: record the exit marker text as status_marker on harvested bash evidence; the leaf detail now reports the marker actually seen instead of asserting a failure indistinguishable from the command's own trailing text. - extend the blocking-IO anchor to drive the probe branch inside the offload; teeth re-verified red->green. * fix(harness): close acceptance forgery and bound gaps from P2 re-review (RFC #4651 PR4) - file leaves: never read unbounded — size is established first (os.stat on the validated local host path, so the host-bash-disabled configuration needs no shell; a guarded wc -c on remote providers that renders missing/unreadable in its own words). Above the 50k cap the leaf answers from the size alone, at/below it the full read runs, and an unestablishable size degrades to UNVERIFIED instead of an unlimited fallback read. - output attribution: source/. prefixes are never provably silent — a crafted */bin/activate path shape says nothing about what the script prints, so sourced segments can no longer lend a passing summary. - executable identity: an explicitly path-spelled criterion now requires the same normalized executable path; the basename rule stays only for deliberately bare criterion commands. * fix(harness): run acceptance size probe outside subagent-controlled state (RFC #4651 PR4) - remote probe no longer runs in the sandbox's persistent shell: a fresh env -i /bin/sh with absolute-path stat/realpath (poisoned functions, aliases, PATH, exported functions, IFS, locale cannot steer it), plus a marker env routing AIO onto a fresh per-call bash.exec session. - metadata-only: stat never opens content, so a FIFO deliverable cannot block the parent for the provider's idle timeout; non-regular files (fifo/dir/symlink) degrade to UNVERIFIED. - containment canonicalized against the literal mount root: a final-component symlink or a swapped parent directory (root included) cannot redirect the check outside shared storage; unprovable layouts degrade to UNVERIFIED. * fix(harness): canonicalize probe containment against the canonical mount root (RFC #4651 PR4) Literal-root equality made every remote file leaf permanently UNVERIFIED on e2b and Tenki, which realize /mnt/user-data as a symlink to the home dir by default (e2b bootstrap 'sudo ln -sfn', Tenki best-effort symlink). Containment now compares the file's realpath against the mount root's realpath — exactly what the provider's own read path resolves, so probe and read-back stay consistent; final-component symlinks stay rejected by the non-dereferencing stat, and an intermediate dir-link escape under a sane root still lands ESCAPED. The inner script is a module constant and the suite now executes the composed probe for real against on-disk layouts (real dir, symlinked prefix, final symlink, fifo, missing, dir-link escape), which the canned-output stub could not see. * fix(harness): close bare-criterion negation and CDPATH summary channels (RFC #4651 PR4) - matching: a criterion with no positional selection target (bare pytest, make test) stands for the runner's default selection, so ANY negating option (--ignore/--deselect/...) makes the recorded run a different selection — unprovable. The overlap guard only sees consumed criterion tokens, which a bare criterion does not have; scoped criteria keep the unrelated-exclusion behavior. - attribution: cd is no longer blanket-silent — CDPATH makes cd print the resolved (subagent-chosen) destination and the pass shapes match as substrings, so one mkdir 'all tests passed' plus an export minted a pass for any quiet command. A cd argument or CDPATH= value (export or leading assignment) carrying any summary shape makes the segment non-silent; shape-free cd dir wrappers keep matching. - docs: _truncate_bash_output states the effective 32-char floor (the guarantee previously read as an unconditional max_chars bound). * fix(harness): close env-assignment and expansion channels in acceptance matching (RFC #4651 PR4) Self-audit in the shape of the last review rounds — channels the matcher classified as accounted-for that can change what runs, narrow the selection, or lend the summary text: - env assignments are no longer blanket-stripped: only an allowlist of inert display/CI knobs (CI, NO_COLOR, PY_COLORS, ...) may prefix a matched span, and a non-allowlisted assignment in any preceding segment (pure-assignment or export NAME=) is state pollution — PATH redirects the executable, LD_PRELOAD/PYTHONPATH/NODE_OPTIONS inject code, PYTEST_ADDOPTS/GOFLAGS/MAKEFILES inject selection-changing inputs, BASH_ENV runs arbitrary shell startup. All degrade to unprovable. - runtime expansions: any span token carrying /$( )/backticks, any negating-option value carrying an expansion or glob (unknown excluded set), and any extra executed token carrying glob metacharacters (crafted option-looking filenames narrow invisibly) are unprovable. Criterion-side globs stay self-consistent (literal match). - cd: an argument carrying a runtime expansion or glob is non-silent (unknown destination, unknown print); CDPATH= assignments are now handled as state pollution at the match layer, subsuming the value-shape special case. * fix(harness): persistent-shell evidence, exact env sets, option-arity scoping (RFC #4651 PR4) - tests_passed: on a persistent-shell provider (new Sandbox.persistent_shell_sessions capability, set by AioSandbox) every leaf degrades to UNVERIFIED — any earlier call in the shared session could have mutated the state the clean-looking run executed in, and only a fresh controlled session (RFC section 6 verifier) can prove otherwise. The flag is read from the provider registry without acquiring a sandbox. - env assignments: the allowlist is gone — no variable is provably inert across repositories (CI/DEBUG are routinely read by tests). The span's assignment prefix must equal the criterion's exactly (values included, order-insensitive); any assignment or export NAME= in a preceding segment is state pollution. - scoping: positional targets are now read by option arity, so a path embedded in an option (--basetemp=/tmp/p, --junitxml=/tmp/r.xml) never counts as a selection target and an extra positional after such a criterion narrows the default selection it denotes. * fix(harness): stamp shell provenance at harvest, close export/unset and arity gaps (RFC #4651 PR4) * fix(harness): split physical newlines as shell separators in acceptance matching (RFC #4651 PR4) * fix(harness): scope cd wrappers to thread data roots, pin accepted boundaries (RFC #4651 PR4) * fix(harness): preserve criterion connectors, prove file_written readable, fail-closed shell capability (RFC #4651 PR4) * fix(harness): compare only the connector prefix, tolerate trailing criterion semicolons (RFC #4651 PR4) * fix(harness): preserve continuation-line operators, keep ./-spelled executable identity (RFC #4651 PR4) * fix(harness): render criteria single-line so a multiline criterion cannot inject a forged checklist line (RFC #4651 PR4) * fix(harness): reject parent-traversal executable tokens in acceptance matching (RFC #4651 PR4) * fix(harness): reject parent-traversal negated values in acceptance matching (RFC #4651 PR4) --- backend/app/gateway/services.py | 28 +- .../agents/middlewares/delegation_ledger.py | 9 + .../harness/deerflow/agents/thread_state.py | 3 + .../community/aio_sandbox/aio_sandbox.py | 16 + .../harness/deerflow/community/boxlite/box.py | 10 +- .../community/e2b_sandbox/e2b_sandbox.py | 12 +- .../deerflow/community/opensandbox/sandbox.py | 10 +- .../deerflow/community/tenki/sandbox.py | 10 +- .../deerflow/sandbox/local/local_sandbox.py | 8 + .../harness/deerflow/sandbox/sandbox.py | 17 + .../harness/deerflow/sandbox/tools.py | 45 +- .../harness/deerflow/subagents/AGENTS.md | 1 + .../deerflow/subagents/acceptance_checks.py | 1396 ++++++++++++ .../harness/deerflow/subagents/executor.py | 211 +- .../deerflow/subagents/status_contract.py | 20 +- .../deerflow/tools/builtins/task_tool.py | 38 +- .../test_task_tool_acceptance_checklist.py | 183 ++ backend/tests/test_acceptance_checks.py | 1930 +++++++++++++++++ backend/tests/test_aio_sandbox.py | 15 + backend/tests/test_boxlite_provider.py | 13 + backend/tests/test_delegation_ledger.py | 50 + backend/tests/test_e2b_sandbox_provider.py | 9 + backend/tests/test_gateway_services.py | 69 + .../test_local_sandbox_command_timeout.py | 13 + backend/tests/test_opensandbox_provider.py | 4 +- backend/tests/test_subagent_executor.py | 362 ++++ .../tests/test_subagent_status_contract.py | 38 + backend/tests/test_task_tool_core_logic.py | 120 +- backend/tests/test_tenki_provider.py | 10 + backend/tests/test_tool_output_truncation.py | 48 +- 30 files changed, 4665 insertions(+), 33 deletions(-) create mode 100644 backend/packages/harness/deerflow/subagents/acceptance_checks.py create mode 100644 backend/tests/blocking_io/test_task_tool_acceptance_checklist.py create mode 100644 backend/tests/test_acceptance_checks.py diff --git a/backend/app/gateway/services.py b/backend/app/gateway/services.py index 8fc64a162..21c6a6553 100644 --- a/backend/app/gateway/services.py +++ b/backend/app/gateway/services.py @@ -76,7 +76,7 @@ from deerflow.runtime.secret_context import ( ) from deerflow.runtime.stream_modes import normalize_stream_modes from deerflow.runtime.user_context import reset_current_user, set_current_user -from deerflow.subagents.status_contract import SUBAGENT_RECEIPT_VERDICT_KEY, SUBAGENT_TOOL_RECEIPTS_KEY +from deerflow.subagents.status_contract import SUBAGENT_ACCEPTANCE_VERDICT_KEY, SUBAGENT_RECEIPT_VERDICT_KEY, SUBAGENT_TOOL_RECEIPTS_KEY from deerflow.utils.messages import ORIGINAL_USER_CONTENT_KEY from deerflow.utils.thread_id import validate_thread_id @@ -121,6 +121,7 @@ _SERVER_OWNED_MESSAGE_METADATA_KEYS = ( TOOL_TRANSFORMS_KEY, SUBAGENT_TOOL_RECEIPTS_KEY, SUBAGENT_RECEIPT_VERDICT_KEY, + SUBAGENT_ACCEPTANCE_VERDICT_KEY, } ) | PROVENANCE_KEYS @@ -272,18 +273,23 @@ def _strip_external_metadata_from_message_like(item: Any) -> Any: return item -def _strip_external_delegation_verdict(entry: Any) -> Any: - """Remove the runtime-stamped receipt verdict from a caller-supplied - delegation-ledger entry. +#: Server-owned verdict keys on a delegation-ledger entry: runtime-stamped +#: execution evidence (citation verdict PR2, acceptance checklist PR4) that a +#: caller must never supply. +_SERVER_OWNED_DELEGATION_VERDICT_KEYS = frozenset({"receipt_verdict", "acceptance_verdict"}) - ``receipt_verdict`` is server-owned execution evidence stamped at task - write-back.

Hot reloads must not make either layer advertise more capacity than the already-created process controller; a changed startup-only value takes effect only after restart. The same middleware separately enforces `subagents.max_total_per_run` (default 6, config schema 1-50, runtime override `max_total_subagents` clamped to the same range) against current-run entries in the durable delegation ledger, so a long lead-agent run cannot bypass concurrency limits by launching repeated legal-sized batches at each planning checkpoint, but historical delegations from previous runs in the same thread do not consume the new run's budget. Explicit `batch_task` work does not consume or relax that ordinary-run ledger: its persisted total/live/running limits live under `subagent_batches`. Gateway `run_agent()` and embedded `DeerFlowClient.stream()` both provide a per-invocation `run_id` in runtime context; `DeerFlowClient.stream()` also tags its input `HumanMessage` with that same id so durable-context capture can identify the current request boundary. Gateway resume paths may not append a new `HumanMessage`, so the worker also exposes the pre-run checkpoint's message ids in runtime context; durable-context capture uses that as the current-run boundary and never re-tags older task calls as the resumed run. When no delegation slots remain, task calls are stripped, provider raw tool-call metadata is synced, `finish_reason` is forced to `stop`, and a visible "subagent delegation limit" note is appended so the agent can synthesize already-collected results. Default subagent timeout `subagents.timeout_seconds=1800` (30 min) and built-in `general-purpose` `max_turns=150`. **Flow**: Ordinary `task()` → `SubagentExecutor` → shared process slot → result polling/SSE. Explicit `batch_task()` → durable batch/item rows → lease-based batch service (`subagents/batch_service.py`, started by Gateway or an explicit direct runtime) → the same `SubagentExecutor`/process slots → bounded stored result and owner-scoped API/JSONL export. Batch mode is selected only by the explicit tool, never inferred from prompt size. Executor queue rejection/timeout occurs before model execution and therefore releases the durable lease without consuming an item attempt; real execution failure and expired leases still consume the retry budget. User cancellation terminalizes every nonterminal item immediately and clears its lease, fencing any stale worker completion. Background cancellation resolves the result/future under `_background_tasks_lock` but calls `Future.cancel()` only after releasing it, because cancellation may synchronously invoke the completion callback that reacquires the registry lock. Direct runtimes provide the tools and worker but not Gateway's HTTP/UI surface. `task_started` carries the resolved effective model name. The per-subagent `SubagentTokenCollector` publishes a cumulative usage snapshot to the shared `SubagentResult` after every completed LLM response; the next `task_running` event carries that snapshot, so collapsed workspace cards can update without re-accounting parent-run totals. Terminal ToolMessage metadata (`subagent_model_name`, `subagent_token_usage`) and the persisted `subagent.end` event retain the model/usage after reload; absent provider usage stays absent rather than being estimated as zero. The executor caches one resolved `AppConfig` snapshot (explicit or `get_app_config()` fallback) for agent assembly, deferred setup, and receipt harvesting, so `verification.receipts_enabled=false` remains authoritative on both construction paths. Terminal tool receipts are harvested before `try_set_terminal` and committed with the other payload fields under the same state lock, so status polling cannot observe a terminal result before its receipt metadata is available. Each yielded values chunk becomes the latest terminal-harvest state and immediately publishes its harvested receipts to the shared result before cooperative cancellation is checked. Tool-ended cancellation/failure evidence uses the current ToolMessage scan, but a completed result always uses the bounded ledger snapshot attached to the assistant text being returned—even when a max-turn partial ends on a later tool chunk—so omitted receipts cannot validate its citations; a missing/malformed completed snapshot fails closed with no receipts. Therefore direct task cancellation and both execution/polling timeouts retain the latest execution evidence even when cancellation interrupts before another stream boundary. **Report contract (RFC #4651 PR3)**: `report_contract.py` owns the prompt-layer text that makes Layer 1 receipt verification non-inert. `SubagentExecutor._build_initial_state` appends `build_report_contract_section(receipts_enabled=...)` to every subagent's consolidated `SystemMessage` — built-in and custom alike — requiring `[rN tool_name]` citations (from the Tool receipts ledger) for action claims, verifiable handles (absolute path, URL, ID, HTTP status) for deliverables, and explicit reporting of failures; the citation clause follows `verification.receipts_enabled`, and the citation example derives from the single-owner `format_citation`/`receipt_id` so prompt text cannot drift from the verifier. The `task` tool hands lead-supplied `acceptance_criteria` to the `SubagentExecutor` constructor, which appends them via `render_acceptance_criteria_block(...)` to the task `HumanMessage` (stripped, capped at 20 items × 500 chars, each entry neutralized) — the untrusted channel `InputSanitizationMiddleware` escapes and boundary-frames, matching their model-supplied provenance. The subagent's `SystemMessage` never carries criterion text; it gets only the framework-owned `build_acceptance_criteria_system_note(...)` pointer naming the list's location and authority, so natural-language injection inside a criterion cannot gain system-channel priority over framework instructions. Deterministic leaf checking is a separate layer. +**Acceptance checklist (RFC #4651 PR4)**: `acceptance_checks.py` checks lead-supplied `acceptance_criteria` in code on the `task` tool's completed branch (offloaded via `asyncio.to_thread`, failure-isolated). Decidable leaves: `file: exists|non-empty` and `file_written:` read through `read_current_file_content` scoped to the shared thread workspace (`workspace_path`/`outputs_path`; virtual `/mnt/user-data/...` prefixes and workspace-relative spellings normalized first) — the read itself uses the sandbox-native virtual form because the local read validator and provider mount tables resolve virtual paths, not host paths; a remote provider's `"Error: ..."` return string (remote providers return instead of raise for missing files) is normalized to a failed check, never evaluated as content — provider-typed via `is_local_sandbox`, so a genuine `Error:`-prefixed file on the local sandbox stays valid content; a UnicodeDecodeError on a text read marks a binary deliverable (PDF/image) as existing and non-empty instead of dropping the verdict; reads are byte-bounded — the size is established first (`os.stat` on the validated host path locally, so the host-bash-disabled configuration needs no shell; a metadata-only `stat`/`realpath` probe in a fresh `env -i` shell on remote providers — absolute-path utilities and a marker env that routes AIO off its persistent shell, so a completed subagent's poisoned session state (functions/aliases/PATH/exported functions/locale) cannot steer it; `stat` never opens content, so a FIFO cannot block the parent for the provider's idle timeout; the file must stat as a regular non-symlink file, and containment is canonicalized — the file's realpath must stay under the mount root's realpath, which is exactly what the provider's own read path resolves (e2b and Tenki realize `/mnt/user-data` as a symlink to the home dir by default), so a final-component symlink is rejected outright and an intermediate dir-link escape under a sane root still lands outside the canonical root), leaves above `_FILE_CONTENT_READ_CAP_BYTES` answer from the size alone — `file_written` only with an added bounded one-byte open probe (stat metadata is not read-back: a mode-000 file stats fine while any open raises EACCES), and smaller files run the full read, and an unestablishable size degrades to UNVERIFIED rather than an unbounded fallback read; out-of-scope paths degrade to UNVERIFIED, never misjudge — on the local sandbox the scope decision canonicalizes with realpath, so a workspace symlink into uploads cannot satisfy a scoped leaf with upload content. `tests_passed:` anchors to a matching bash execution (newest match wins) with `status=success` and a test-summary shape in its bounded output tail — each harvested execution carries a `shell_persistent` provenance stamp — the producing sandbox's `persistent_shell_sessions` flag (AIO's legacy exec path) resolved from the state that carried the evidence, never the parent runtime, which has no `sandbox` key when the parent delegated before touching one — and a persistent stamp (or an unidentifiable or undeclared one — a custom provider that never declared its session semantics is unknown, not fresh-shell; unknown provenance fails closed) degrades the leaf to UNVERIFIED instead, because any earlier call in the shared session could have mutated the state the clean-looking run executed in and a fresh controlled session (RFC §6 verifier) would be needed to prove otherwise, harvested by the executor (`_harvest_bash_executions`, only when criteria were delegated) from the same stamped `ToolMessage`s the receipt layer reads, accumulated per streamed chunk (merged by `tool_call_id`, newest-capped) so subagent summarization compacting earlier messages cannot erase a recorded execution, with over-cap commands carrying `command_truncated` so the matcher degrades to UNVERIFIED instead of proving a match on a suffix-less prefix; the recorded status is the actual shell exit status parsed from the output's `Exit Code: N` / `Command exited with code N` marker (a nonzero bash exit returns ordinary text that `deerflow_tool_meta` still reports as success; local/e2b/opensandbox/tenki/boxlite all append the marker on nonzero exit with or without output, aio propagates the SDK's structured exit_code on both exec paths, and local timeouts append `Exit Code: 124` and signal kills parse as signed markers (`Exit Code: -9` records error), and `_truncate_bash_output` always preserves a trailing exit marker inside its budget — a 32-char floor raises any smaller configured limit, and the remote `Command exited with code N` form is accepted only as the whole trimmed output — so truncation cannot erase the failure; the matched marker text travels on the entry as `status_marker` so a `tests_passed` detail reports what was seen instead of asserting a failure the harness cannot distinguish from the command's own trailing text), falling back to the meta status only when no marker exists; matching is shell-structure aware (operator-separated segments — a physical newline separates with `;` semantics — or with the continuation operator the next line opens with (`cmd1\n&& cmd2` is `&&`; `cmd1\n|| cmd2` is `||`, which after a successful first command skips the rest while exiting 0, so flattening it to `;` would record a run that never happened) —, so a multi-line script's trailing `echo`/`seq` lines are never merged into the matched segment's arguments, status, or output attribution —, executable identity — directional: a bare criterion executable accepts any path spelling of the name, while an explicitly path-spelled criterion requires a path-spelled execution of the same normalized executable path (spelling judged on the raw token: `./pytest` names the project-local file and normpath collapsing `./` must not demote it to a PATH lookup; a `..` component on either side is unprovable outright — `link/../pytest` normalizes to `pytest` textually, but the OS follows `link` before resolving `..`, so lexical normalization cannot prove identity), so `/tmp/fake/pytest` cannot certify `/opt/project/.venv/bin/pytest` —, ordered argument subsequence whose env-assignment prefix must equal the criterion's exactly as an effective name → final-value mapping — extra, missing, or differently-valued assignments degrade the match, as does any reordering of a repeated name (`CI=0 CI=1` vs `CI=1 CI=0` are last-wins opposite environments), since no variable is provably inert across repositories (`CI`/`DEBUG` are routinely read by tests; `PATH`/`LD_PRELOAD`/`PYTEST_ADDOPTS`/`MAKEFILES` change what runs), and any assignment or argumented `export`/`unset` in a preceding segment is state pollution, and any span token carrying a runtime expansion (`$VAR`/`$( )`/backticks) or an extra token carrying glob metacharacters (crafted option-looking filenames narrow invisibly) is likewise unprovable), so a command that merely mentions the criterion string (`echo '12 passed'; # pytest x.py`) cannot anchor the leaf, and control flow is preserved — the matching span must end at the command's last segment with provable execution (`&&` needs recorded success, `||` needs recorded failure, pipelines inside the span and backgrounding are never provable), and the criterion's own connectors are preserved — an expected `&&` executed as `;` (`cd missing; pytest x` for `cd missing && pytest x`) lets a failed preceding step be bypassed, so it degrades; only the stricter direction (criterion `;` executed as `&&` with recorded success) survives), so a short-circuited segment (`false && pytest x; echo '3 passed'`) degrades to UNVERIFIED instead of a false hold; the summary shape is evaluated only when the output is attributable to the matched segment (every preceding segment provably silent by invocation form — only shape-free `cd dir` and pure assignments qualify; `pushd`/`umask`/`ulimit`, any `export`/`unset` (an invalid identifier prints bash's `not a valid identifier` error carrying subagent-chosen text — `export 'all tests passed'; make test` — and valid forms are state pollution), and any `source`/`.`, whose `*/bin/activate` path shape says nothing about what a crafted script prints, are not — so neither `echo '12 passed'; make test` nor a sourced forge can lend the shape; the `cd` print channel is closed too — CDPATH makes `cd` print the subagent-chosen resolved path and the pass shapes match as substrings, so a `cd` argument carrying a summary shape or runtime expansion is non-silent, and any `CDPATH=` assignment degrades the match as state pollution), pass shapes require a nonzero passed count (`0 passed`, go `[no test files]`, `Ran 0 tests` veto), argument matching treats tokens consumed by negating options (`--ignore`/`--deselect`/`--exclude`/`--skip` families) as ineligible evidence (`pytest --ignore tests/security tests` cannot affirm the excluded tests) and a target negated anywhere in the command degrades the match (`pytest tests/security tests/unit --ignore tests/security` cannot certify the excluded target), and a bare criterion with no positional selection target (bare `pytest`, `make test`) treats ANY negating option as a different selection (`pytest --ignore tests/security` never ran the default selection the criterion means), and accepts extra executed flags only when provably selection-preserving (verbosity/output/xdist/coverage forms; `-k`/`-m`/`--lf`/`--collect-only`/`-c`/`-p` and friends degrade to UNVERIFIED — `pytest -k smoke tests/security` cannot certify the full selection; extra positionals widen only after a path-scoped criterion — scoping reads positional targets by option arity, so a path embedded in an option (`--basetemp=/tmp/p`, `--junitxml=/tmp/r.xml`) never counts as a target, and an option of unknown arity (absent from the value-taking table, no glued `=`) followed by a path-like token (`--rootdir /tmp/project`) fails closed — the token may be the option's value, so the criterion keeps no scoped-selection proof —, so `python -m unittest pkg.OneTest` cannot certify bare `python -m unittest`), and criterion text is neutralized with `neutralize_untrusted_tags` before storage/rendering so a blocked tag in a criterion can never reach the lead-visible checklist section. Any other criterion is UNVERIFIED, never silently passed. The verdict (`subagent_acceptance_verdict` in `additional_kwargs`, validated on read) feeds the delegation ledger's `acceptance:` segment and the model-visible checklist section appended to the result text; the gateway strips caller-forged verdicts from both ledger entries and message metadata like the citation verdict. Leaf read errors catch only `OSError`/`SandboxError` — unexpected errors propagate to the task-tool-level isolation so the blocking-IO gate keeps teeth (`tests/blocking_io/test_task_tool_acceptance_checklist.py`). Known accepted boundaries (pinned by `TestKnownBoundaries` — conscious, do not re-raise): a bare criterion executable trusts PATH/filesystem spelling (a subagent-crafted same-name script is textually indistinguishable; spelling an absolute criterion path restricts evidence to that normalized path); relative criterion targets resolve in the wrapper's cwd, so `cd` prefixes must stay in scope (relative without `..`, or absolute under the thread data roots / virtual prefix) while a symlink inside an allowed root pointing out is a filesystem-layer concern; runner semantics are trusted (a Makefile swallowing failures, a runner exiting 0 on failure) — Layer 2 is execution evidence only, claim correctness belongs to the PR5 judge / RFC §6 re-execution; evidence is bounded (500-char command, 1000-char tail) and truncation degrades to UNVERIFIED rather than proving. **Events**: `task_started`, `task_running`, `task_completed`/`task_failed`/`task_timed_out` **Handled LLM failures**: `LLMErrorHandlingMiddleware` deliberately converts provider/model exceptions into an `AIMessage` so the graph can end cleanly, stamping `additional_kwargs.deerflow_error_fallback=true` plus error metadata. Clean graph termination does not imply subagent success: `SubagentExecutor` inspects the last assistant message at terminalization and maps a marked fallback to `SubagentStatus.FAILED`, which then emits `task_failed` and the existing structured `subagent_error`. Only the marker is authoritative — error-looking assistant prose without it remains a normal completed result, so neither the executor nor frontend parses display text as a status protocol. **Guardrail caps & `stop_reason` (#3875 Phase 2)**: three independent axes can end a subagent run early, and all now surface *why* through one additive field rather than a new status enum. **Turn axis**: `recursion_limit` on the subagent `run_config` equals `max_turns`, so exhausting the turn budget raises `GraphRecursionError` from `agent.astream`; `executor.py::_aexecute` catches it specifically (before the generic `except Exception`). **Token axis**: `TokenBudgetMiddleware` is attached per-agent via `build_subagent_runtime_middlewares` from `subagents.token_budget` (default `max_tokens` **coupled to `summarization.enabled`** — 1,000,000 when subagent summarization is on, 2,000,000 when off, warn at 0.7, hard-stop at 1.0; a user-set budget always wins regardless of the switch — #3875 Phase 3; a backstop against a subagent that burns tokens on trivial work). It does *not* raise: at the hard-stop threshold it strips the in-flight turn's tool calls, forces `finish_reason="stop"`, and lets the run complete naturally with a final answer. **Loop axis**: `LoopDetectionMiddleware` (attached at the same point) catches repeated identical tool-call sets — or one tool *type* called many times with varying args — and its hard-stop likewise strips `tool_calls` and forces a final answer without raising, recording `loop_capped`. Each guard exposes its cap on a per-`run_id` `consume_stop_reason(run_id)` accessor; `_aexecute` collects **every** middleware with that method (duck-typed via `hasattr`, so the executor has no import coupling to the guard classes) and surfaces the first non-`None` reason — adding a future guard needs no executor change. **Surfacing**: whichever axis fired, `_aexecute` stamps a normal status plus an additive reason — `completed` + `stop_reason=token_capped|turn_capped|loop_capped` when a usable final answer (or partial recovered from the last streamed chunk via `_extract_final_result` → `utils/messages.py::message_content_to_text`, returning a `"No response Generated"` sentinel when no text survived) was produced; `failed` + `stop_reason=turn_capped` when nothing usable survived. `SubagentResult.stop_reason` flows through `task_tool.py::_task_result_command` → `format_subagent_result_message` (renders `Task Succeeded (capped: ...)` / `Task failed (capped: ...)`) and `make_subagent_additional_kwargs`, which stamps the additive `subagent_stop_reason` key alongside the normal `subagent_status`. **Why additive, not an enum**: a new status value would break v1 consumers; an optional field is ignored by older frontends and ledger readers, so the cross-language contract (`contracts/subagent_status_contract.json` v2 + `subagents/status_contract.py` + `frontend/.../subtask-result.ts`, pinned by `test_status_values_match_contract` / `test_stop_reason_values_match_contract`) stays backward-compatible. The durable delegation ledger captures `stop_reason` onto the entry and renders model-facing guidance ("hit a guardrail cap with a partial result; reuse it, retry tighter, or raise the per-agent budget (`max_turns` / `token_budget`)") so the lead reuses a capped completion knowingly instead of mistaking it for a clean one. (Phase 1 shipped this surfacing as a `MAX_TURNS_REACHED` status enum in #3949; Phase 2 replaced that enum with the additive `stop_reason` field per the agreed design — the `max_turns_reached` status value and `SubagentStatus.MAX_TURNS_REACHED` are gone.) diff --git a/backend/packages/harness/deerflow/subagents/acceptance_checks.py b/backend/packages/harness/deerflow/subagents/acceptance_checks.py new file mode 100644 index 000000000..a56a66163 --- /dev/null +++ b/backend/packages/harness/deerflow/subagents/acceptance_checks.py @@ -0,0 +1,1396 @@ +"""Deterministic acceptance-criteria checks (RFC #4651 PR4). + +Layer 2 of the verification stack: the lead attaches ``acceptance_criteria`` +to a ``task`` delegation (PR3 wired the parameter and the prompt contract); +this module checks the decidable criteria *in code* once the subagent +completes, so a self-report can never silently pass an objectively checkable +requirement. + +Leaf families: + +- ``file: exists`` / ``file: non-empty`` — read through + ``read_current_file_content`` (the ``ReadBeforeWriteMiddleware`` + precedent), **scoped to the shared thread workspace**: the path must + resolve under the thread's ``workspace_path``/``outputs_path`` (virtual + ``/mnt/user-data/...`` prefixes and workspace-relative spellings are + normalized first).
