Backport current benchmark agents and runner lifecycle from dev/tui

[furgalep]

What does this PR do?

Backports the current benchmark agents from dev/tui: single python_cell execution, automatic summarization, method writing, bounded delegation, and Todo updates merged after successful worker cleanup. BenchAgent and the delegation-oriented RLMBenchAgent share the same capabilities; both await workers and return TaskResult with solution, observed evidence, and How to Verify.

Workers share the model client, summarization configuration, and workspace path, with separate shells and histories. Supplied context is an ordinary worker-method argument: NOOA renders it with its existing parameter formatting and makes it available in the Python namespace. No custom delegation renderer or redaction policy.

Default delegation depth is four; strategy settings are ten retries and a 1,800-second cell timeout. Awaited delegation shares the parent cell deadline. Timeouts cancel the worker without merging partial Todo state and do not consume the strategy retry counter; the enclosing harness budget limits repeated attempts. These semantics are now documented, not changed.

Review follow-up

• Promote CodeActV2 (nooa.CodeActV2 or nooa.strategies.CodeActV2). Remove CodeActLiteStrategy, its exports and obsolete formatter/tests; the evaluation CLI offers codeact_v2. Breaking removal documented in CHANGELOG. CodeActStrategy remains the default, but its model-visible fixes are explicitly documented.
• Keep CurrentCall mutable for its live execution namespace, while preserving its correlation ID. The Task event's display tag now has its own field. Event filtering by the current call works for both strategies.
• Preserve validated inline-return values on real execution outputs without fabricating provider tool-call history. Retain original task arguments after compaction; restore concise context usage and compaction guidance for both benchmark variants.
• Resolve output reserves from UnifiedLLM's actual request settings (client defaults, selected reasoning level, per-call cap). Context percentages, automatic summary triggers and overflow recovery use the same usable input window. Unknown caps are labelled planning reserves; explicit summarizer thresholds stay fixed. Context management rejects a configured cap at or above the known window instead of installing a one-token summary budget; valid large caps retain their actual reserve. Normalize Responses reply caps to max_output_tokens and replace inherited cap aliases. Tests inspect actual serialized requests for all three interfaces, sync and async.
• Make Todo updates/restores atomic. Migrate legacy notes and non-done statuses through the real stored-session deserializer, not only TodoManager.from_dict. Document downgrade data loss.
• Keep completed results and worker state recoverable when Todo merging conflicts, introduces worker-only dependencies, or the worker removes its delegated Todo.
• Drain cleanup under repeated owner cancellation, including child-task re-entry. A cancelled cleanup callback no longer drops later callbacks or cancels unrelated closers.
• Export archived and active events with actual IDs. Failed trajectory exports invalidate prior-task artifacts and cannot produce new metrics from stale data. Debug failures do not prevent successful task/verifier output.
• Correct V2 recovery tool names, live input-type reporting after reassignment, and method-writing/delegation prompt examples. _working_directory_context is explicitly @no_trace, inherited by RLMBenchAgent.
• Fix Python-tool handling in ACP, Playground and trace display. For no-ID execution traces, require matching code before selecting a following model turn; do not infer prefill solely from missing IDs.
• Improve same-cell alias and starred-gather behavior metrics. Schema version 2 rejects incompatible artifacts; regenerate old reports from trajectories. Metrics cover controller history, not worker cells or runtime loop counts.
• Preserve ACP subprocess checkout isolation. Verify the runner's actual working-directory argument and resource lifecycle.
• Authenticate trace-explorer viewer paths and honor proxy settings. Authenticated HTTP retains a sanitized warning for compatibility; HTTPS-only enforcement remains a separate viewer/exporter policy decision, not a claim made by this PR.
• Match ShellTools.run_stream(command, *, stdin=None, timeout=30.0) to run, including the coding activity wrapper and bounded stdin event recording. Empty stdin now works in the shared helper. Existing positional streaming timeouts must be passed by keyword.

Stack

main → #331 → #337 → #330 → #346 → #347 → #350 (dev/tui). Merge bottom-up. Base: main (bb1f948f). Downstream layers must retain the CodeActV2 rename when rebased. Existing main OAuth, SnapshotVars, caching and tool-choice fixes are retained.

Validation

Latest candidate: 94792d6c. Offline tests used Python 3.13.11 and pytest 9.1.1. Regression tests were observed failing before fixes, then passing. The context-budget audit also caught and fixed Responses calls silently dropping max_tokens and Anthropic calls ignoring a reply cap left only in extra_body. Wren accepted the preceding candidate with one context-window guard requested; this candidate adds that guard (12 observed failures before the fix, all 38 focused tests passing afterward).

Changed Python files pass Ruff lint and formatting checks; git diff --check passes. The test environment needed the already-declared msgpack dependency; no project dependency was added. No live model calls were needed for these regressions.

Streaming follow-up: pytest tests/tools src/nooa/tools/tests packages/nooa-cli/tests/test_coding_activity.py -q — 353 passed, including signature parity, stdin payloads/empty input, exit status, bounded activity recording, persistent shell framing and recovery. Wren has been asked to review the frozen head before merge.

Individual review replies record fixes and subsequent corrections. Reviewer resolution and merge approval remain separate; this update does not assert every additional audit follow-up is closed.

291-303: 🩺 Stability & Availability | 🟡 Minor | ⚡ Quick win

Cleanup exceptions can replace a completed benchmark result: after _run writes the result and artifacts, an exception from agent.close() or llm_client.aclose() propagates through asyncio.run, causing a successful task to exit with status 1. Isolate and log cleanup failures while preserving the original execution or write exception so resource shutdown cannot falsely fail a completed benchmark run.

Heads-up: two fixes from the SWE-bench Pro batch-10 wrap-up are relevant to this backport but not currently in it (verified against the branch: grep for both comes up empty). They're sitting on furgalep:dev/tui (2 commits ahead of this backport's dev/tui base point), ready to cherry-pick if wanted:

1. fix(trace-explorer): send viewer auth headers and honor proxy env — the trace-explorer thin client sent no Authorization headers (auth-enabled viewers 401 every call) and set trust_env=False (bypasses the corporate proxy required for viewer egress on this host class — every call died with ConnectError). Adds viewer_headers() (Bearer from NOOA_VIEWER_AUTH_TOKEN) wired into all httpx client constructors. Verified end-to-end against a live viewer.

2. feat(codeact-experimental): make python_cell_context the unified execution context — removes the separate execution_context block for CODEACT_EXPERIMENTAL; python_cell_context now IS the execution context (symbol stub with from-imports included, plus module labels), so from-import-only adapters get a populated block instead of an empty one, and it's memoized per agent class (static, cacheable prefix). Offline TUI suite passes 7/7; the live fixed-prompt benchmark run confirmed the populated block in every turn-1 system message — and that run flipped qutebrowser FAIL→PASS.

(1) is a plain bugfix that applies anywhere trace-explorer is used. (2) changes the benchmark agents' context layout — relevant to this backport since it touches src/nooa/strategies/codeact_experimental.py, which this PR carries in its older two-block form.

Also addressed the outside-diff runner cleanup finding from review 5198355410 in 7a8cc7e. Ordinary exceptions from synchronous or asynchronous agent/client shutdown are logged independently, client shutdown is still attempted after agent cleanup fails, and cleanup cannot replace the result or an execution/artifact exception. Cancellation remains propagating. Twenty parametrized cases cover both cleanup styles and success, reported failure, execution error, write error, and cancellation; the initial sixteen cases reproduced the failure before the fix.

The two inline findings are fixed and replied to. The three previously resolved CodeRabbit findings (short rendering budgets, Todo status documentation, and adjacent-turn prefill correlation) remain covered by passing tests. #330 has been restacked onto this head and passes 281 integration tests, with its own patch unchanged.

Published adb0504 with the remaining deep-review fixes and replies to all four new inline findings.

• Cleanup is cancellation-safe: concurrent close calls share the shielded drain, and repeated caller cancellation propagates only after callbacks finish. Tests exercise actual summarizer cleanup before shell/client release.
• ACP subprocess tests are pinned to the checkout again. The runner regression now passes working_dir by name and checks the worker's cwd.
• CHANGELOG explicitly declares model-visible CodeAct changes, Todo downgrade data loss, PersistentVars rules, DelegationMergeError, and benchmark changes.
• Shared cell-state/prompt rules replace duplicated versions; method-writing examples follow automatic argument rendering.
• New regressions cover Todo variable/comment merge conflicts, Todo.v APIs, non-string trailing expressions, and non-TaskResult evaluation returns.
• Fresh CodeRabbit fixes: camelCase credential redaction, HTTPS-only authenticated viewer requests, and following-turn lookup for no-ID prefills.

Validation: 1,633 passed / 3 xfailed in the bench/ACP/strategy/context/trace/Todo selection; separately 1,300 passed / 8 skipped / 69 deselected in runtime+agents. Exact commands are in the updated PR body; counts are not a deduplicated total. Ruff passes. No live calls.

Human threads remain available for reviewer confirmation. Wren has the frozen SHA for re-verification. #332 is still paused; no merge performed.

Updated in b3f033f: Python cell context is a single commented Python block (including real import aliases), DelegationMergeError stays recoverable but is hidden from the advertised namespace, and benchmark guidance requires verification before claiming completion. ShellTools now explicitly directs command/file operations through its four methods; run_stream documents direct async iteration with exit/timeout inspection rather than pyp. Ambiguous replace(Match, old, new) fails before file access with corrective guidance. Also fixed the CI-discovered default-strategy prompt binding: template self is the agent, so strategy restrictions are now passed explicitly.

Verification: observed failing tests before the context/doc changes and passing tests after. Broad selection: tests/strategies tests/runtime tests/agents tests/context_blocks tests/test_initial_llm_messages_no_errors.py tests/tools/test_shell_tools_modern.py tests/tools/test_shell_tools_modern_behavior.py tests/tools/test_builtin_libs.py packages/nooa-bench/tests — 2762 passed, 3 skipped, 69 deselected. After the final two documentation contracts, tests/tools/test_shell_tools_modern_behavior.py tests/tools/test_bash_session_framing.py — 44 passed. Ruff check/format and git diff --check pass. No live model calls in this delta. CI for the new head is not yet verified.

[furgalep]

Updated in f01d08d per review: TaskResult now uses how_to_verify (schema title: How to Verify) rather than command_to_verify. It describes verification steps and expected results; shell commands are optional, and observed evidence remains separate. Updated generation guidance, runner result serialization, README and changelog. The TodoManager usage example now activates exploration before work and activates the dependent fix after completing exploration.

Verification: new schema tests first failed against the old command-only field, and the example test first failed for missing activation. After the changes, packages/nooa-bench/tests tests/unit/test_todo_status.py tests/unit/test_todo_comments.py: 192 passed. Tests cover non-command instructions through evaluation output and execute the actual Todo docstring example. Ruff check/format and git diff --check pass. New-head CI remains pending.

[furgalep]

Restored context_usage for both BenchAgent and RLMBenchAgent in ca87df8. It displays provider-reported context usage, output reservation and attributed context/event breakdown. Manual-compaction guidance is omitted for these automatically summarized agents; the shared formatter retains its previous default for other callers. The automatic python_cell_state block remains disabled.

Verification: the new presence/prompt tests first failed for both agents; the formatter opt-out test first failed with an unsupported keyword. After the fix, packages/nooa-bench/tests tests/context_blocks/test_context_stats.py tests/strategies/test_codeact_v2.py: 190 passed. Formatter tests cover known/unknown usage, preserved defaults and high-usage warnings. Ruff check/format and git diff --check pass. New-head CI not yet verified.

[furgalep]

Updated in b337133: the agent-facing self.events.collapse API accepts integer endpoints when their string forms identify existing events, including archived originals and mixed string/integer boundaries over prior summaries. Successful conversion prints one reminder: Please use strings for event tags next time (e.g. '2', not 2). Missing numeric endpoints, booleans and floats are rejected before history changes. String-only calls stay silent; the archive implementation is unchanged.

Verification: observed the integer failures before implementation, then 323 tests passed across tests/runtime/test_events_api.py tests/test_event_manager.py tests/runtime/test_event_manager_events.py tests/unifiedllm/test_collapse_replay.py tests/strategies/test_codeact_v2.py packages/nooa-bench/tests. Tests cover memory and SQLite, nested summaries, invalid-input preservation, and a full CodeActV2 turn proving the warning appears in the next model request. Ruff check/format and git diff --check pass. New-head CI is not yet verified.

[furgalep]

Final adjustment in c19998e: valid integer collapse tags are now accepted silently, per request. Removed the warning while retaining endpoint validation and mixed/nested-summary support. This supersedes the warning described in the previous update. Tests first reproduced the unwanted warning, then 79 tests passed across tests/runtime/test_events_api.py and tests/strategies/test_codeact_v2.py; the full agent-turn test confirms no warning reaches the model. Ruff check/format and git diff --check pass.

Updated at 8dcaf13. Context status, percentages, automatic summaries and overflow recovery now resolve the configured reply cap through UnifiedLLM, including reasoning-level and per-call settings. Unknown caps are labelled planning reserves; explicit summary thresholds stay fixed. Request-body tests cover Chat, Responses and Anthropic in sync and async modes, including the cap translations uncovered by this audit. ShellTools.run_stream and its activity wrapper now match run: command, *, stdin=None, timeout=30.0. The shared helper also handles empty stdin. Verification: 4,979 passed / 3 skipped / 74 deselected in the core/runtime/agents/bench selection documented above; 353 passed in the tools and activity selection. Ruff and diff checks clean. Requested Wren review of this exact commit; not merged.

[furgalep]

Follow-up to the context-budget review: 94792d6 rejects a configured reply cap at or above the known context window with an actionable error. This prevents a one-token automatic-summary budget. Valid large caps retain their real reserve and percentages; unknown limits retain labelled fallback behavior. Regression evidence: 12 failures observed before the fix, all 38 focused tests pass afterward; the documented broad selection now passes 4,993 tests (3 skipped, 74 deselected), Ruff clean. Wren has the frozen SHA for final re-verification. No new model calls or private registry edits. PR body updated; not merged.

[furgalep]

Second review, head 94792d6 (Wren).

Verdict: accept. Reviewed in depth across five areas (strategies, benchmark package, runtime/storage/tools/ACP, review-thread closure, tests) at f44e38d, then re-verified each follow-up on exported trees: adb0504, 18fd5bd, 8706f60, 8dcaf13, 94792d6.

Verified by reproduction on the final head:

• Sessions saved by main restore through the real snapshot path: legacy blocked status maps to open, notes survive as description (Todo.__restore_snapshot__).
• A worker that completes and then prunes its todo raises DelegationMergeError carrying the finished result and worker state.
• EventManager.aclose is cancellation-safe: a callback closing the manager through a subtask returns instead of deadlocking; a callback that lets CancelledError escape no longer drops the remaining callbacks or leaks cancellation to other closers; the summary drain finishes before shell and client close.
• Context limits: the effective reply cap (client default, selected level, per-call, extra_body) drives stats, usable-window percentage, automatic summarisation and overflow recovery; recovery keeps the effort level and lowers the cap; a cap at or above a known window raises an actionable error instead of producing a one-token budget.
• Default CodeActStrategy changes (delegation prompt wording, validated inline value on replay, non-object tool-argument retry) are declared in CHANGELOG; downgrade loss of Todo descriptions is declared.
• All 39 review threads answered; 26 fixed and verified, 2 declined with stated reasons.
• No gateway hostnames, private routes, key names or live numbers in the diff. Built frontend assets follow repository convention and match the source edits.
• Suites on the exported head: 3,695 (unifiedllm, runtime, agents, tools, context_blocks, unit, bench) and 3,967 (with trace_explorer, viewer, ACP, coding agent) passed; the only failures are the two ACP console-script cases that also fail on main in this environment.

Not claimed: the lower-priority items from the max-effort review (loader error types, alias-import detection in the analyzer, duplicated tool-name sets across six consumers, TodoManager.update deep-copy cost, status() size, PersistentVars/AgentVars duplication, missing docstrings on three new public members) remain open by the author's own statement and are not blockers.
