fix(quota): preserve explicit Todo selection gates and retry

[LIHUA919]

Summary

An explicit Todo request could be refused by a replan, workspace or write-scope gate, then reported as heartbeat_receipt_identity_conflict even when the Turn had no settlement identity. Preserve the TypeScript qualification result and return quota_action_selection_rejected or quota_action_selection_deferred, with deterministic guard re-entry and no receipt creation, upgrade or quota spend.

Recompute qualification after final workspace/scope guards while preserving their selected identity. Normal admitted selection, exact due-monitor obligations and committed-identity conflict rules remain unchanged. Failed preflight under --turn-envelope retains its typed packet and complete re-entry command.

中文：修复显式 Todo 选择把真实准入阻塞误报为回执身份冲突的问题。保留 replan、工作树、写入范围、能力和认领边界；最终 guard 改变准入时重新计算类型化资格，返回原 Goal/Agent/Turn 的重入路径，失败不写或升级回执、不扣额度。

Issue Or Task

• Refs quota: explicit Todo selection can reject the canonical runnable successor #4327; covers the monitor-successor failure and a canonical add-after-pending-guard boundary failure.
• Contributor task ID: explicit Todo selection admission and retry.
• The reproduced monitor failure has a present canonical candidate but a deferred long-chain replan gate. The add-after-guard fixture reaches final workspace/scope repair. This PR reports those actual gates; it does not label an unverified source divergence as projection_stale or change the current-frontier admission policy.

Validation

• Tested revision: df1c6889485cfffef5ecebfcfb01b5a30e0ccc96.
• Run state: finished.
• Input classes: synthetic, public_fixture.

Check kind	Result	Public-safe evidence / limitation
real_entrypoint	passed	73 tests across explicit successor selection, quota settlement CLI, action portfolio, boundary selection, identity preconditions and error codes.
real_backend	passed	Disposable File and SQLite stores plus legacy state; actual monitor mutation, canonical Todo add, pending guard, selection, receipt readback and retry. Node 22.22.3 / SQLite 3.51.3.
regression_parity	passed	The same test_explicit_successor_selection.py fails on immutable main 7eb4b7bb1661bd5eff63a8725a33169792d5964b for both canonical long-chain and add-after-guard cases, returning the old identity-conflict code. Both pass on the candidate.
integration	passed	Existing managed Turn advisory-primary CLI test and two TurnEnvelope validation-failure tests pass. Host execution/model calls are not exercised. A system-installed tests package initially shadowed the repository namespace; the managed test passed with imports explicitly scoped to repository tests.
unit	passed	17 TypeScript action-portfolio and quota-selection tests; their rule implementations are unchanged.
static	passed	Ruff, compile, diff checks and public/private scans.
integration	passed	Risk premerge: 4 direct checks and 18 selected checks; zero failures, warnings or skips. Includes CLI output budgets, monitor/scheduler contracts and maintainability.
integration	passed	Exact-head GitHub CI: Sign-off and merge-gate passed, including all four Python shards, Stage 2C correctness, installed-package, Node compatibility, packaged dashboard, and Windows checks. CI run. Publish/deploy jobs were skipped as expected for this PR.

Coverage and gaps: no store implementation, provider routing, promotion, score, persisted Todo schema or default capability change. PostgreSQL integration is not applicable to this CLI diagnostic/qualification projection change; File/SQLite are the reproduced entrypoints. A distinct case with an actually admitted default candidate and unavailable explicit source would need its own minimal fixture. No active Goal data or model/benchmark jobs were used.

Future-facing pass: moved existing explicit-selection validation/confirmation together with failed-preflight recovery into quota_action_selection.py; the main command handler passes the existing complexity ratchet. The TypeScript qualifier remains the semantic owner. #4061's fallback-source work is unchanged.

Frontend / Visual Evidence

• UI impact: none. The changed user entrypoints are explicit quota CLI selection and failed --turn-envelope output. No setting, frontend control or configuration projection changes; managed Turn keeps the shared eligibility owner.
• Before / After / Viewports: N/A.
• Source data: synthetic.

Thank you for the concrete reproduction and File/SQLite coverage. The canonical fix has now merged via #4335 as main b0f7aa0, and #4327 is closed. Before closing this duplicate, I ran your exact tests/control_plane/test_explicit_successor_selection.py against that merged main: 7/7 passed, including legacy/File/SQLite, the long waiting chain, deterministic retry/no duplicate receipt, and canonical add-after-guard behavior. Merging both implementations would now create a second CLI selection transport beside the existing TS qualification + quota wrapper owner. Closing as superseded, not as a rejection of the contribution: your reproduction and provider matrix materially strengthened the accepted boundary and post-merge verification.

[LIHUA919]

Thank you for the clarification and for crediting the reproduction/provider coverage. I agree that the full #4332 transport should not be merged alongside #4335.

I independently checked the remaining delta in an isolated checkout pinned to merged main b0f7aa0d12eab1947808d5af3f46ac51d37ec794, with pytest and CLI helpers confirmed to load that checkout. Copying the unchanged tests/control_plane/test_explicit_successor_selection.py from df1c68894 (SHA-256 f15d292ecb967ca65b9545c56b7eaf8a427f44fc460e276f01ec0094efd4a78a) and running python3 -m pytest -q tests/control_plane/test_explicit_successor_selection.py produced 4 passed, 3 failed:

• Two failures are only the intentional action_selection versus action_selection_qualification field difference; I am not treating those as functional blockers.
• test_canonical_add_after_pending_guard_reports_final_boundary still exposes a narrow scope-guard recovery gap. In the real synthetic File fixture, the final decision is boundary_projection_repair, normal_delivery_allowed=false, and self_repair_allowed=true, while qualification remains qualified. The CLI then raises requested action selection qualification conflicts with its projection and returns quota_unexpected_collection_error plus heartbeat_receipt.status=write_failed.

The guarded early return in _resolve_agent_lane_delivery_route preserves the first-pass qualification instead of refreshing it after the final scope guard. The same fixture on #4332 returns typed deferred/control_repair without a fake receipt. This concerns the scope-boundary branch, separate from the workspace-repair recovery already added in #4335.

Could we retain this as a small follow-up on the merged implementation—keeping its inventory/TS owner and workspace-repair behavior, and adding only final scope-guard qualification plus the focused regression? No need to reopen or merge the full duplicate PR.

嗯，感觉 sol 搞错了，这个我 reopen

动机

评审对象是 exact head 4332@df1c6889485cfffef5ecebfcfb01b5a30e0ccc96。PR 的目标是修复显式 --todo-id 在 replan、workspace 或 write-scope 最终 guard 之后被误报为 heartbeat_receipt_identity_conflict 的问题。这个问题仍有真实增量：在当前 origin/main@0933d48efc058d9e1585bd30058942416aa258a9 上，Todo 在首轮 guard 之后新增、随后要求 loopx/** 写范围时，focused fixture 仍返回 quota_unexpected_collection_error，没有保留类型化资格。旧 PR 的测试在它自己的旧基线通过，但整个 seven-file diff 已与当前 main 的 #4335 运行时/协议 transport 重叠。

改动思路

入口是 quota should-run --codex-app --todo-id，资格的语义 owner 是 TypeScript action-selection reducer，should_run_packet.py 组装最终 delivery route，quota.py 负责 CLI 诊断与 heartbeat receipt。旧 PR 中 _resolve_agent_lane_delivery_route 的 final-guard ordering 修复是有价值的；但是新增 quota_action_selection.py、新的 action_selection 字段、协议文档和大批 monitor/retry 测试，与当前 main 已有的 _apply_requested_quota_action_selection_preflight、action_selection_qualification 和现有回执测试形成第二套 transport。rebase 到当前 main 时 quota.py 与 settlement 测试发生冲突，确认了这不是一个适合整批合入的增量。

正向路径应是：先从 canonical agent Todo inventory 得到 qualification，再冻结 selected identity 并返回最终 workspace/scope guard；deferred/rejected 只返回 typed diagnostic，已有 identity-less receipt 只 replay，不写新 settlement identity、不扣额度。最小修复是保留现有 owner，只移动 qualification 计算位置并加入一条 late-selection boundary regression。

具体改动

关键代码讲解

• loopx/control_plane/quota/should_run_packet.py::_resolve_agent_lane_delivery_route（约 549 行）：旧 main 在 guarded-agent-lane 分支直接 return，跳过 qualify_action_selection_from_inventory。PR 的最后一个 commit 将资格计算移到该 return 之前，保证 control_repair/delivery_not_allowed 仍能以 derived action_selection_qualification 输出，同时不改变 selected Todo identity。
• loopx/cli_commands/quota.py::_apply_requested_quota_action_selection_preflight（约 390 行）：当前 main 已是 CLI/receipt transport owner，负责把 deferred/rejected 转成 quota_action_selection_deferred/rejected、回放现有 receipt 并阻止 settlement。旧 PR 新增的 parallel helper 与 action_selection 字段不应再保留。
• loopx/control_plane/work_items/action_portfolio.py::qualify_action_selection_from_inventory（约 134 行）：继续作为 inventory-to-TS qualification adapter；没有新增状态源或 authority。
• tests/control_plane/test_explicit_successor_selection.py 的 monitor cases 与 tests/control_plane/test_quota_settlement_cli.py 现有 guard cases 大量重复。真正缺少的是 late Todo + final boundary guard 的 canonical File fixture，应合并进现有 quota settlement suite。

对主干的风险

旧 exact head 直接合并会带来一个 P1 阻塞：它在当前 main 上是 stale/conflicting，并行引入第二个 explicit-selection transport，造成 action_selection 与 action_selection_qualification 两种公开字段和两套 retry owner；后续消费者可能把同一 deferred state 分流成不同错误码。该 batch 的 +522/-85 规模相对于当前只缺一个 ordering branch 是 disproportionate。

已验证的负向场景是：当前 main 的 early return 会让 late selection 退化为 quota_unexpected_collection_error；同一 real CLI/File-authority fixture 在把 qualification 前移后返回 quota_action_selection_deferred、reason=control_repair，现有 identity-less receipt 为 replayed 且 rollout event 数量不变。default/unselected、workspace repair、newly-due monitor、autonomous replan 和 user-gate 邻近场景均保持通过。没有新增 Todo authority、持久化 schema、quota spend、provider 或 capability activation。

请求修复（P1）：将本 PR 收敛为现有 should_run_packet.py owner 中的 final-guard ordering 修复和一条 focused regression；删除/不合入已由当前 main 提供的 parallel CLI module、旧协议重复说明及重复 monitor 测试。对应回归为 tests/control_plane/test_quota_settlement_cli.py::test_selection_added_after_pending_guard_reports_final_boundary。

验证：旧 exact head 的 test_explicit_successor_selection.py 为 7 passed；当前 main 的 focused reproduction 在修复前复现错误码；收敛后的 two-commit patch 的 focused + 邻近 5 cases、完整 test_quota_settlement_cli.py（58 passed）、boundary/CLI suites（25 passed）及 Ruff/diff checks 通过。loopx canary premerge --from-git-diff 的 direct checks 和大多数 smokes 通过；quota-plan-smoke 在基线与修复分支均受 capability-memory effect-runtime fixture 失败影响，catalog-run-e2e-smoke 用项目 Python 直接运行通过但被 canary wrapper 报失败。这两项属于环境/基线证据，不是本 diff 引入的回归；应以推送后的 GitHub CI 为最终门禁。

我的整体评价

当前 #4332 exact head 不能合并，结论是 REQUEST_CHANGES。它包含一个正确且仍有价值的 final-guard ordering 修复，但其余改动在当前 main 上主要是重复实现/重复覆盖。收敛后的实现保持 TS qualification、Python quota transport 和 heartbeat receipt 的单一 owner，并以最小 real-path regression 锁定之前未覆盖的 boundary 分支。完成收敛、推送新 exact head 后应重新 review，不能继承本次结论或旧的 CI 通过状态。

English verdict: REQUEST_CHANGES for 4332@df1c6889485cfffef5ecebfcfb01b5a30e0ccc96. The final-guard qualification ordering is a valid incremental fix, but the seven-file head duplicates current main’s quota transport and exposes a second selection field/owner. Keep the existing TS/Python owners, retain the focused late-boundary regression, and drop the superseded module/docs/duplicate tests. Baseline reproduction shows quota_unexpected_collection_error; the focused repair returns typed quota_action_selection_deferred without receipt mutation.

[huangruiteng]

Superseded by the self-refined follow-up #4350, which rebased the remaining final-guard qualification fix onto current main and merged it after exact-head review and CI. The original seven-file transport remains closed because #4335 already supplied its overlapping owner/contract.

[LIHUA919]

收到，谢谢重新核验并完成修复。看到剩余的 final-guard qualification 问题已通过 #4350 收敛并合并，这个处理方向我认同：沿用主干现有的 TS qualification 和 quota/receipt 处理，只保留 final guard 前刷新 qualification 的修复，以及 late-selection boundary 回归，避免引入重复的 transport、协议说明和测试。

原 #4332 由 #4335 和 #4350 接续覆盖后关闭没有问题。谢谢保留这条边界回归；后续如需我补验证或调整，直接 @ 我即可。
