 [acceptance contract](../../reference/goal-acceptance-observations.md#owner-authorized-contract-v0).
 This narrows a local recovery gap, not the full R1/R2 coordination acceptance.
 
+**R1 first delivery checkpoint.** New ordinary CLI/MCP/managed work admissions
+persist their original result basis before execution and enforce freshness at
+the existing Todo owner. Default identity acquisition restores the unfinished
+Turn; settled work releases a new work identity. Relevant Todo, dependencies,
+acceptance and source changes require candidate revalidation, while unrelated
+revisions do not. Original successful receipts survive response loss and cold
+recovery. Legacy Markdown is read-only and cannot authorize Todo mutations;
+File/SQLite and PostgreSQL result transactions retain their typed head/CAS owner. See the
+[operating protocol](../../reference/protocols/goal-vision-replan-contract-v0.md#opt-in-first-delivery-freshness).
+New supported admissions also persist the default current-Agent checkpoint
+continuation contract. Required checkpoints use the actual post-result, complete
+relevant frontier read; MCP returns it to the current tool caller, while managed execution
+resumes its original Host/session. Noncompletion outcomes retain their original
+receipt and use the existing supplement owner. Related direction changes require
+only a new direction judgment, preserving successful results and single spend.
+Definitively rejected progress writes retain their candidate for original-Turn
+revalidation. Ordinary direction preserves independent Agent lanes; original
+no-followup still requires the whole Goal. Supplementary direction includes
+registered primary Goal documents under the same registry fence. Chat treats
+unavailable observations as read failures with read-only recovery, not pending settlement.
+The source candidate retains classified direction stops and permits explicit
+original-Turn reentry under current launch gates; unknown historical stop
+records stay held. Receipt-bound replanning keeps its semantic ACK behind the
+fresh direction, and settled selected planning obligations are excluded from later work
+inference while ordinary progress retains original-Turn recovery. These are recovery mechanics, not evidence of new model utility.
+Ordinary terminal completion uses the existing same-Turn upgrade after checkpoint
+and spend. Historical result-only, explicit first-delivery and supplement Turns
+retain their persisted contract. Complete changed-frontier recovery, packaged
+frontend/Lark journeys, mixed-version rollback and live-model utility remain
+unfinished first-stage acceptance. Source-session remains lifecycle-only and
+ordinary Python PostgreSQL execution still lacks its service-owned factory.
+An independent reviewer needs a separately registered optional contract. These
+defaults do not close R1, certify Goal completion, establish distributed atomicity
+or demonstrate model-outcome gains.
+
+Recovery qualification now includes lost or damaged work-read receipts after
+original result commit and historical result-only terminal revalidation after a
+proved progress writeback, and an unfinished delegated Todo after Turn settlement.
+The native index proves the original work row even after a direction supplement.
+Sealed lifecycle recovery compares closeout at the canonical store's timestamp
+precision, preserving same-second admission/closeout without adopting old terminal work.
+Unknown commits and mismatched identities remain
+rejected. The packaged Chat recovery smoke uses the existing same-origin relay
+and an isolated Host profile; deterministic replay evidence does not qualify
+installed Lark, mixed-version rollback or live-model utility.
+
 **R1 transaction checkpoint.** Team-plan admission and whole-batch planning now live in `work_items/team_plan.ts`. Confirmation assigns all admitted lanes in one write with a durable operation receipt; identity is proposal + lane, never Todo text. File/SQLite authority uses the existing CAS and receipt owner; legacy Markdown writes the records and immutable receipt together under its existing fence and lock. Exact replay reads historical results even after a receiver changes, completes or deletes work. A precommit failure creates no lane prefix, and pending canonical display delivery requires recovery before Chat reports verified success. The card names partial assignments and gaps; quota/stop remain advisory and an explicit enforcement claim is rejected. Agent-originated settlement binds the same state basis at its journal's first write and re-reads it at settlement; a plan whose basis is missing or moved, or whose every lane is a gap, is a typed failed receipt that creates no Todo and replays unchanged.
 
 This closes the local assignment/retry portion of F4, not R1's collaboration acceptance. Registered receivers are assigned without being impersonated as authors; agent-originated settlement cannot assign another peer without owner confirmation. Assignment does not attest receiver adoption, a lease, execution, dependency consumption or independent acceptance. Do not add a second confirmation to ordinary already-authorized work. Gap resolution requires new explicit intent; replay must not silently extend the confirmed subset. The fingerprint binds current local state and canonical revision, not a full shared Goal-intent transaction. Local registry and active-state guards now remain held through the typed commit: native token claims survive caller exit, changed source bytes reject new assignments, and expired handoffs can only replay an exact committed receipt. Registry contention returns a retryable failure without creating work; canonical display recovery runs after the source guards release. Failed retry-safe Team Plan proposals retain their original review identity after Goal or manager workspace reload; retry revalidates current source facts and recovers existing assignments rather than generating a new proposal. Stale, gated and unsafe failures remain unavailable for this recovery, including in the already-open drawer. Chat recovery resolves the current registered Goal and source before receipt lookup; a removed Goal or unreadable bound source can block recovery. Canonical display recovery follows the current registered source, so this slice does not recover a deleted source binding. R2/R3/R4 still own executor qualification, receiver adoption/result return and shared intent/authorization; the cross-host Turn lease is not a plan barrier.

+**R1 首次交付检查点。** 新的普通 CLI/MCP/托管执行在工作前持久化原始结果依据，由现有 Todo owner 在提交时检查新鲜度。默认身份恢复未完成的 Turn；结算后才释放新的工作身份。相关 Todo、依赖、验收和来源变化要求重新验证候选结果，无关修订不会触发。成功回执支持响应丢失和冷恢复。Legacy Markdown 只读，不能授权 Todo 写入；File/SQLite 与 PostgreSQL 结果事务沿用类型化 head/CAS owner。见[操作协议](../../reference/protocols/goal-vision-replan-contract-v0.md#opt-in-first-delivery-freshness)。
+
+新的受支持准入还保存当前 Agent 的默认 checkpoint 续跑契约。需要检查点时读取结果提交后的完整相关任务前沿；MCP 返回给当前工具调用者，托管执行恢复原 Host/session。非完成结果保留原回执并使用现有补充 owner。相关方向变化只重做方向判断，保留成功结果和单次扣费。确定被拒的进度写回保留候选，在原 Turn 重验；普通方向保持独立 Agent lane 隔离，原 no-followup 仍要求全 Goal。补充方向在相同 registry fence 下包含注册的主 Goal 文档；Chat 将观察不可用显示为读取失败并提供只读恢复，不称为待结算。普通终态完成在 checkpoint 与扣费后使用同一 Turn 的升级路径。历史 result-only、显式 first-delivery 及 supplement Turn 沿用保存的契约。完整的前沿变化恢复、打包前端/Lark 旅程、混合版本回滚与真实模型效用仍是未完成的一阶段验收。Source-session 仍只支持生命周期；普通 Python PostgreSQL 执行仍缺少 service-owned factory。独立 reviewer 需要单独注册的可选契约。这些默认值不关闭 R1、不认证 Goal 完成，也不证明分布式原子性或模型收益。
+
+源码候选保留已分类的方向停止，并在当前派发门约束下支持原 Turn 显式重入；未知历史停止仍被阻断。回执绑定的重规划在新方向返回后才验收语义 ACK，已结算且验收所选规划义务的 Turn 不再与后续工作竞争，普通进度仍保留原 Turn 恢复。这些是恢复机制，不是新增模型效用证据。
+
+恢复资格还覆盖原结果提交后工作读取回执丢失或损坏、已有进度写回证明的历史 result-only 终态重验，以及 Turn 结算后尚未完成的委派 Todo。native index 在方向补充之后仍证明原工作记录。sealed 生命周期恢复按 canonical store 的时间精度比较关闭时刻，保留同秒准入/关闭，不采纳旧终态工作。未知提交和身份不匹配继续拒绝。打包 Chat 恢复烟测复用现有同源 relay 和隔离 Host profile；确定性重放证据不认证 installed Lark、混版本回滚或真实模型效用。

+
+The failed Windows CI host emitted 28,334 characters for the one-Todo candidate;
+its main multi-Agent observation was already 25,975. Preserve both failures.
+The added information is the original read basis, causal admission/replan
+receipt, original-work progress readback and memory-call observation; the replan also carries the current planning
+choice. Do not remove these inputs to meet an older presentation ceiling.

+
+### Default result freshness and current-Agent checkpoint continuation
+
+Result freshness now belongs to ordinary new work admissions. Local-registry
+CLI `quota should-run`, MCP `should_run` and managed `turn run-once` persist the
+original Turn's complete result basis before exposing or dispatching work.
+An unbound observation carries no selected work basis. Choosing a Todo through
+its returned selection command upgrades that original receipt using the same
+typed freshness admission policy as a direct selection. Historical already-bound
+receipts retain their original policy; replay cannot silently enroll them.
+CLI allocates or restores a Turn when no Turn parameter is supplied; ordinary
+`todo complete` restores that Agent/Todo's original identity and read key.
+Ambiguous pending Turns fail closed instead of selecting the latest key.
+Automatic CLI/MCP identity acquisition serializes the existing selection,
+heartbeat append and work-input persistence under one scoped IO fence. Lock
+timeout remains a failure; it cannot allocate a second Turn. Explicit Turn
+callers retain their existing identity and lease rules; mixed explicit/automatic
+calls do not gain a global single-Turn guarantee. MCP completion and vision
+recovery restore the admitted identity; the older deterministic host identity
+remains a compatibility fallback when there is no default work admission.
+Legacy Markdown is read-only and rejects Todo mutations with
+`canonical_authority_required`; File/SQLite use their existing
+typed Todo head/CAS owner. PostgreSQL result-only reads use the provider head and
+identity, with the final check on the native Todo transaction head. Source-session
+remains a lifecycle-only profile under its existing runtime admission restriction.
+No capability, provider or actor write authority is added. Required checkpoints
+continue the current Agent after the durable result; typed exemptions add no
+direction call.
+For unfinished work already admitted through ordinary MCP `should_run`, use
+`wait_task(todo_id, agent_id, reason)` for a quiet typed wait. It restores the
+original Turn and checks its current guard, leaves the Todo open, and performs
+no direction call, lifecycle completion, writeback or quota spend. It does not
+repair a completed result's pending direction; use `review_task_vision` and the
+original completion intent for that recovery. Resume unfinished work through
+`should_run` when ready and revalidate a retained candidate on changed facts.
+
+Default mutating entrypoint qualification targets local-registry File and SQLite;
+Legacy Markdown coverage is limited to reads and rejected writes. PostgreSQL has native result transaction/head/CAS conformance;
+the ordinary Python CLI/MCP/managed runtime does not supply the existing
+service-owned PostgreSQL factory. A PostgreSQL selector therefore fails closed
+without legacy fallback; this slice does not add that product integration.
+The packaged Chat regression exercises the existing **Continue review** control,
+production HTTP/controller and native checkpoint owners on a disposable Goal.
+It retains the original SDK session, Todo, Turn and committed result, reads fresh
+direction facts, settles once, then reloads and replays without another debit.
+Its SDK transport is deterministic and unrelated workspace navigation is a
+synthetic shell; the checkpoint HTTP responses come from the production owner.
+Run the public smoke described below for the exact candidate being delivered.
+This does not qualify live model judgments, native Desktop rendering or live Lark
+delivery. The four legacy Lark recovery entrypoints and PostgreSQL first-delivery
+callers remain unqualified. These are delivery limits, not an option to silently
+bypass freshness on a protected admission.
+Manual Todo lifecycle operations without any work admission retain their existing
+permission and validation contract. They have not captured an Agent work basis
+and are not qualified result-freshness execution. Absence of an admission is not
+proof of a historical Turn. Once work is protected, manual omission of identity
+or read key cannot downgrade its result obligation.
+
+For ordinary admitted CLI work, neither command needs a first-delivery switch,
+Turn parameter or manually copied read key:
+
+```sh
+loopx --format json quota should-run --goal-id example --agent-id agent-a \
+  --todo-id todo_page --codex-app
+# Work and validate against the returned delivery_result_context.
+loopx --format json todo complete --goal-id example --agent-id agent-a \
+  --todo-id todo_page --note "Candidate verified against the original work basis."
+```
+
+Related Todo, transitive dependency, acceptance, source or lease changes reject
+the old candidate eligibility before result effects. Unrelated provider revisions
+and display-only changes do not require another judgment. Native command and
+acceptance validation retain their existing authority and bind the actual candidate
+and issued validation receipt to the original read identity. Managed validation
+also receives that work basis. A new read cannot relabel cached validation.
+
+Native Todo display loss does not erase native Todo authority. The Goal's
+frontmatter and non-Todo objective/acceptance prose still belong to the Goal
+document owner. Losing that whole document blocks full-basis execution; restoring
+Todo sections alone does not restore Goal intent. Such projections carry
+`goal_source_completeness=todo_projection_only`; the exact older unmarked
+recovery codec has the same meaning. Checkpoint admission rejects this state.
+Use the existing `loopx-project` recovery route to locate and restore actual
+owner source or backup, then retry the original Agent/Turn. Preserve an already
+admitted heartbeat receipt; failed basis reads do not dispatch work or spend.
+Native Todo read/write and lease operations keep their existing authority.
+No automatic reconstruction of missing Goal narrative is claimed.
+
+Protected reads also bind separately registered `authority_sources` of kind
+`goal_doc`, using the existing primary-document declaration. Their current text
+is returned as `basis.goal.prose`, with paths and normalized-text digests in
+`basis.goal.primary_documents`. The previous state prose remains available as
+`basis.goal.state_prose`; it does not replace the primary requirements. All three
+participate in Goal freshness, without duplicating primary document bodies.
+Rewriting the Agent state file cannot remove that independent requirement basis;
+an unavailable primary document blocks the read without reconstructing it from
+old plans. With no separate document, the existing state-file basis is unchanged.
+Plans and Todos remain derived records. A changed requirement alone is not
+projection corruption or permission to restore older requirements. This is not
+shell write isolation: hosts needing that guarantee must keep owner documents
+outside Agent-writable files **and directories**, while leaving Todo state writable.

+remains readable. Brief and ordinary thin share the current-contract worker;
+captured TurnEnvelope execution retains its independent saved-observation rules.
+These representation changes do not reduce the work-basis obligation or prove
+model cost or utility.
+
+After a stale result, MCP calls `should_run(revalidate_todo_id=TODO)` and revalidates
+the retained candidate before retrying ordinary `complete_task`; keys travel
+automatically. CLI reads `checkpoint-context --purpose delivery_result` for the
+returned original Turn, revalidates, then retries ordinary completion. Managed
+`--resume-turn-key TURN --retry-failed-turn` retains the candidate and original
+session, rereads and invokes the current Agent to validate it. The retained
+candidate and revalidation instruction survive receipt/journal update and cold
+dispatch recovery. Exact successful Todo receipts take precedence over later
+basis changes, including loss of the result response before refresh/writeback.
+For historical result-only admissions, if a managed terminal Todo is rejected after refresh/spend,
+those receipts and the outer transaction prefix remain fixed. The original Turn
+records bounded Host/validator revalidation progress; retry resumes that progress
+and then only the pending Todo closeout. It cannot rewind or repeat settlement.
+Host or validation failure keeps the terminal result pending and preserves the
+settled receipts. This does not supply the remaining changed-frontier redirection
+or independent Goal acceptance contract.
+
+New supported admissions also persist `checkpoint_continuation=current_agent_v1`
+in the original heartbeat receipt. Ordinary completion commits the result before
+reading the complete post-result Goal frontier. The current Agent must author a
+new Vision patch or an unchanged reason bound to that read. An unchanged reason
+requires an existing Vision baseline. Pre-result judgments are not accepted as
+this judgment; a new key cannot relabel a cached response. The existing checkpoint
+owner retains cadence, material-trigger, in-flight and blocked-retry exemptions.
+
+MCP `complete_task` returns `direction_pending`, `completed=true` and
+`settlement_complete=false` with the actual context and original Turn identity.
+The current tool caller retains its original completion arguments, consumes that response and continues
+`complete_task` with its returned `read_context_id` and new decision, without
+`first_delivery=true`. `review_task_vision` rereads on stale direction. CLI callers
+use the equivalent checkpoint-context/refresh commands below for the original
+Turn; the CLI transports facts and cannot manufacture an Agent judgment.
+
+Managed `turn run-once` automatically dispatches `phase=checkpoint_direction`
+through the original Host after committing a completion result, or after retaining
+an original noncompletion outcome requiring a supplement. Generic adapters must
+consume `checkpoint_context` and echo its read ID with the decision; older adapters
+that only implement the work-result response remain pending until adapted.
+Codex resumes the exact original native session, including a fresh-per-Turn work
+session. Operation transport offers no operation tools during direction. DSH
+retains the original lineage/iteration session ID. No independent reviewer is
+required or invoked. Host failures use the existing retry policy; stop and
+permission failures retain the result without a fabricated judgment.
+
+Cold recovery uses `turn run-once --resume-turn-key TURN --retry-failed-turn`.
+Successful result, checkpoint and quota receipts win over a lost response. A
+stale direction invalidates only its judgment; implementation and validation stay
+cached. Ordinary no-followup completion preserves its original terminal intent,
+commits the result with an intermediate continuation, then uses the existing
+same-Turn terminal upgrade after checkpoint and spend. The Todo owner persists
+`completion_requested_continuation=no_followup` when deferring a stored closeout;
+this intent is not a terminal recovery receipt and applies only to its original
+completion identity. An explicit MCP `no_follow_up` request is replayed with its
+original completion arguments; the facade does not infer that intent from a new
+frontier or a replacement Agent. This does not certify Goal
+completion or supply the complete changed-frontier scheduling contract.
+
+A definitive pre-commit freshness rejection of a progress writeback uses the same
+prepared-effect abort and retained-candidate recovery as completion. Cold retry
+revalidates that candidate against the new basis on its original Turn; an
+unknown effect is not treated as a proved rejection.
+
+The typed owner selects the complete relevant Agent lane and dependency closure
+for an ordinary current-Agent direction checkpoint. Independent peer-only updates
+do not invalidate it. Original no-followup intent still requires the complete
+Goal frontier, regardless of a caller's narrower scope. Supplementary direction
+reads and commits include the same registered primary Goal documents and registry
+fence; changing or losing a document requires recovery before a new decision can
+commit. Exact committed receipt replay retains its historical result.
+
+An unavailable observation without an original settlement identity is not a
+pending settlement. Packaged Chat shows that read failure and offers a read-only
+reread; restoring its source does not itself dispatch or spend.
+
+Historical receipts without this mode retain their prior contract, including
+result-only and already-spent missing-checkpoint supplement recovery. Unknown
+modes and downgrade attempts fail closed. The explicit `first_delivery` v2
+protocol remains compatible, including its historical protected-terminal limit.
+Rolling back to an older writer while a new-mode Turn is pending is unsupported:
+retain the new writer to recover those Turns, or restore a consistent pre-admission
+snapshot through the existing owner procedure. Do not delete mode fields or
+rewrite receipts to disable protection. Packaged frontend/Lark operation, complete
+terminal redirection, mixed-version rollback and live-model utility remain
+separate acceptance. These defaults do not complete the maintainer's first stage.
+
+The stages are independent: prepare and validate the candidate, commit the
+allowed result operation, read the resulting state, judge the direction outside
+source/provider locks, commit that direction, then finish ordinary settlement.
+An independent reviewer
+requires its own registered input, result and recovery contract.
+Neither Todo completion nor a satisfied direction checkpoint certifies Goal
+completion.
+
+The ordinary quota guard returns the persisted basis before work. To explicitly
+reread after a stale rejection, or to enter the separate direction protocol:
+
+```sh
+loopx --format json checkpoint-context --goal-id example --agent-id agent-a \
+  --todo-id todo_page --turn-instance-id turn-1 --purpose delivery_result
+```
+
+Validate against that basis. Explicit protocol callers may pass its `read_context_id`
+as `--delivery-read-context`; default callers restore the persisted key. Retain the Goal, Agent, Todo, Turn and original
+candidate/validation options. The Todo owner checks historical receipts first,
+compares relevant facts against its current authority head, and commits an exact
+delta and receipt with revision CAS. Unrelated revisions may retry without
+another model decision. A related change requires rechecking the candidate.
+
+After the allowed result commit, read the direction:
+
+```sh
+loopx --format json checkpoint-context --goal-id example --agent-id agent-a \
+  --todo-id todo_page --turn-instance-id turn-1 --purpose first_delivery \
+  --decision-scope goal
+```
+
+Read the returned basis and produce a new Vision or unchanged reason. Submit it
+using the existing delivery fields plus `refresh-state --first-delivery
+--checkpoint-read-context ID --progress-scope goal`. Both `agent_lane` and `goal`
+scopes bind complete membership and dependency closure. Reading more work grants no authority to write another Agent's work.
+Final submission protects registry, Goal state, index and the real provider
+through append. It rejects `--next-action` and Codex session usage booking as
+compound effects; explicit usage observations can accompany the run. Lock order:
+index, registry, maintenance, Todo projection, state, then provider. Model calls
+and validation commands stay outside this section.
+
+MCP callers use `complete_task(first_delivery=true)`. The v2 protocol first
+returns `result_review_pending` with a result context. Validate, then call again
+with `delivery_read_context_id`; it commits the ordinary completion and returns
+`direction_pending`. Judge that context and call again with both
+`delivery_read_context_id` and `read_context_id`, plus the new Vision/reason.
+`review_task_vision(first_delivery=true)` can reread a rejected direction; it
+never attaches a new token automatically to an old Vision. Protected
+`no_follow_up=true` is rejected before any effects are admitted in that explicit
+direction protocol. Its native no-followup rejection applies after historical
+receipt recovery. Default result-only protection uses the existing legal terminal
+owner and adds no blanket no-followup rejection. Ordinary v0/v1 completion now
+checks default result freshness. Historical admissions retain their prior ordering;
+new current-Agent admissions use result → direction → refresh/spend → terminal.
+An indexed successful direction can settle its original owed quota slot once.
+A new terminal upgrade still checks the captured actual Goal source; a typed
+Todo-only projection cannot authorize that write. Restore the owner's document
+and resume the same Turn, retaining successful result and quota receipts. An
+exact already committed terminal receipt is recovered before this new admission
+check. This does not certify Goal acceptance or solve changed-frontier continuation.
+The remaining changed-frontier stage must provide the legal transition for a changed
+frontier after checkpoint or spend; retrying a refused terminal intent is not
+that transition.
+
+Status and quota readbacks expose `first_delivery_progress`: result and
+direction commits, quota spend, pending stage and recovery action. Shared and Agent-scoped
+status mirror recovery text into the existing next-action field used by the
+dashboard and channel projections. These receipt observations are neither new
+workflow authority nor a Goal completion signal.
+
+Malformed or unreadable historical receipts are reported as scoped
+`observation_errors`, never as proof that no recovery is pending. If the damaged
+receipt cannot be attributed to a Turn, `observation_unavailable` retains the
+Goal-scoped warning while leaving unrelated lanes' next actions intact. An
+enrolled Turn whose original readback is uncertain stays `operation_unknown`;
+recovery writes remain blocked until the original artifacts can be reconciled.
+Observation reuses one complete canonical Todo snapshot across the discovered
+identities; it does not truncate older pending work.
+
+Ordinary Todo completion recovers an exact terminal receipt before checking an
+unreadable optional enrollment source, without changing its request fingerprint.
+Managed recovery carries the original journal's work key after the Todo owner
+confirms the same Turn's successful result. A subsequently missing or damaged
+result read receipt cannot erase that commit or trigger another validation or
+settlement. The optional direction enrollment still requires its own receipt.
+For a new completion, the original Turn's verified ordinary writeback can prove
+that a damaged shared supplement is optional. Missing or inconsistent history,
+an enrolled writeback, or any result enrollment receipt remains
+`checkpoint_commit_unknown`; unreadable JSON alone never proves non-enrollment.
+
+After a lost response, retry the original request. `checkpoint-context` for its
+first-delivery identity verifies an indexed direction and artifacts before
+returning `committed`. A proved empty append can retry after freshness validation.
+JSON/Markdown without a complete consistent index remains
+`checkpoint_commit_unknown`: preserve the original identity and artifacts for
+operator reconciliation; another Turn cannot bypass that unresolved append.
+The files, provider, quota and Git are not one transaction.
+
+Omitting first-delivery leaves the historical explicit enrollment inactive; it
+does not disable default result freshness or a new admission's current-Agent
+checkpoint continuation. Historical admissions without these policies retain
+their original rules, including supplement recovery. New protected admissions cannot
+downgrade through omitted identity/key, false flags or an older Host schema.
+There is no per-command switch to disable an admitted result obligation. Before
+rolling back a runtime, finish or reconcile pending protected Turns with a
+compatible runtime; preserve original receipts and successful artifacts. This
+does not add cross-host atomicity, Goal certification or model-quality guarantees.
+
+An original committed Todo result remains replayable if its disposable work-read
+receipt is lost or damaged; the typed completion proof, rather than a new read,
+owns that recovery. On a historical result-only Turn, a verified indexed writeback
+may precede an unfinished terminal result. Only matching identity, work context
+and recovery evidence allow another result read in that lane. A settled Turn with
+its original quota debit may
+also validate its still-unfinished Todo, using the proved original work writeback
+rather than a later direction row. Pending current checkpoint lanes retain exact
+writeback replay; missing or conflicting commit proof stays fail-closed.
+An unclaimed successor must be claimed before its work admission.
+
+An unreadable historical read cannot block an independent checkpoint when its
+digest-named path is attributable to an exact indexed effect and that effect's
+JSON/Markdown artifacts pass the existing receipt-first verification. Inspection
+does not rewrite the old read. A work-only proof establishes only the work read,
+never a pending direction append. Unknown paths, incomplete indexes, missing or
+conflicting artifacts and unindexed direction attempts remain fail-closed.
+Status and packaged UI observations use the same native proof to recover the
+original binding; a verified direction never erases pending quota accounting.
+This includes deletion of both disposable reads. Coordinator checkpoint reads
+and recovery follow the registered Goal runtime even when Chat storage is separate.

+Use the checkout's compatible Python test environment, supported Node and frontend
+lockfile dependencies. The browser smoke needs Playwright and a headless Chromium;
+`LOOPX_PLAYWRIGHT_PACKAGE` and `LOOPX_CHROME_HEADLESS_SHELL` may select existing
+local installations. Its output includes actual HTTP observations, native result
+and settlement records, desktop/narrow screenshots and browser errors. A missing,
+failed or skipped check is an open evidence gap; a source test run does not qualify
+a different installed artifact.
+
+Receipt-bound recovery preserves the original semantic obligation and cadence
+source instead of deriving a replacement from the current schedule. Missing,
+changed or foreign source facts fail closed; no implicit historical-source adoption
+is granted. A committed monitor poll may close its own Turn without an accountable
+work writeback or quota debit. Unbound settlement diagnostics must not report that
+exact proved poll as old unpaid work. The execution guard still verifies its
+committed metadata against the bound Todo; an arbitrary settled-looking flag is
+not admission authority. The File/SQLite public tests retain wrong-identity,
+missing-proof and replay negatives.
+
+Local-registry File/SQLite caller coverage and Legacy Markdown read/rejection coverage are distinct from
+PostgreSQL native head/CAS conformance. Service-owned PostgreSQL first-delivery
+factory integration remains outside this qualification. Lark contract tests use
+synthetic transports; live delivery and the four legacy recovery routes remain
+unqualified. Two platform-specific Lark lifecycle scenarios have POSIX-only
+coverage and must not be presented as Windows support. These boundaries also apply
+to any packaged build, regardless of a successful frontend smoke.
+
+For rollback, stop new admissions, preserve original receipt/journal/source blobs,
+then finish or explicitly reconcile pending protected Turns using a compatible
+runtime. Check source, interpreter, original identities and unresolved append state
+before switching a task-owned launcher to a retained qualified installation. Never
+relabel an earlier receipt as evidence for the new build, reimplement a durable
+result or charge a replay. The regression for an unchanged result also preserves
+its original completion timestamp. Global installation changes, integration with a
+newer main and remote publication are separate operations with their own validation.
+This support note does not certify a Goal, live model usefulness or a release.
+
+Code publication remains a separate operation. Qualify ref CAS against an
+integration target that is not checked out; this protocol does not wrap direct
+Git writes or promise concurrent working-directory isolation. If publication
+responds ambiguously, read the integration status and exact current SHA, verify
+that combined candidate, then use the existing `integration-branch sync
+--candidate-ref SHA --execute` recovery. This can adopt the already published
+candidate without moving the branch again. A clean merge is not task acceptance:
+run the task verifier on that combined SHA before confirming its result.

+### Direction stops and explicit original-Turn recovery
+
+A direction Host's `wait`, `user_action_required` or `iteration_failed` retains
+the result and records its existing result kind and attempt in `direction_stops`.
+Read-only `checkpoint-context` preserves this history and the stopped marker.
+Explicit `--resume-turn-key` together with `--retry-failed-turn` may retry the
+unfinished direction; it cannot replace the original result, validator, Host
+session or settlement identity. Current activation, permission and quota are
+checked again at Host launch. Retry counters and Host failure budgets are never
+reset. A recorded Host `stop_reason`, malformed/unknown stop history, and an
+uncertain commit remain held. An older boolean-only stopped receipt supplies no
+stop-classification evidence and is not silently rearmed.
+
+For a receipt-bound semantic replan, the default post-result checkpoint may
+retain the result before the current Agent has authored its direction. Its
+pending checkpoint is neither an accepted semantic delta nor permission to
+spend. The original obligation is qualified on the fresh supplement; completion
+validation still belongs to the later Todo completion. A settled Turn for a selected
+planning obligation cannot compete with its later work admission. Ordinary
+progress and completed Todos retain their original-Turn recovery paths.
+
+Checkpoint artifact paths may use an alias of the same physical runtime
+directory. New records use physical paths before their record/index projections
+are constructed; replay verifies historical aliases without rewriting their
+stored paths or fingerprints. The owner resolves the parent directory only,
+rejects symbolic-link artifact leaves and external directories, and retains the original
+identity, lock witnesses and provider fence. A replaced directory cannot supply
+the admitted append merely by containing identical bytes.
+
+A required direction checkpoint and a selected semantic-replan obligation are
+separate conditions. A current evidence-backed Vision can support a freshly
+judged unchanged decision; it cannot discharge a pending selected replan without
+the existing typed semantic evidence. Once that obligation is accepted and
+settled, a later work Turn does not inherit it. Todo validation and whole-Goal
+terminal checks still apply independently.

+An explicit retained-candidate reread through MCP restores the admitted original

+Observation is read-only. It reuses one Todo fact projection, one settlement
+snapshot and one strictly checked checkpoint index per batch; it neither repairs
+read receipts nor authorizes a direction retry. The strict checkpoint parser
+still rejects incomplete tails and competing proofs. A disagreement between its
+index capture and the settlement capture stays uncertain. Historical scans are
+complete, including damaged/deleted read receipts with matching indexed artifacts;
+the output remains one pending original Turn or scoped unavailable evidence.
+
+| Existing contract | Producer and consumer | Retained responsibility |
+| --- | --- | --- |
+| Host transaction v0/v1 | `host_adapter_settlement.py` → `host_todo_completion.ts` | Ordinary completion and Vision/context supplements remain active callers. |
+| Host transaction v2 | Explicit MCP first delivery **and** default `current_agent_checkpoint` → the same typed owner | Wire `first_delivery=true` does not imply an opt-in-only feature. Preserve their different terminal rules and original admission policy. |
+| `delivery_result` / `first_delivery` / supplement reads | Checkpoint capture/commit and historical inspectors | Original work evidence, post-result direction evidence and supplemental authoring have separate identities/purposes. |
+| Completion identity and requested no-followup | Todo completion → `completion_state.ts` and settlement | Current display state cannot reconstruct or replace the original terminal intent. |
+| Direction returns, stops and attempts | Python Host transport → `checkpoint_read_context.ts` → locked Python receipt IO | One typed owner classifies returns and produces the receipt transition. Actual Stop reasons, response bindings and accumulated attempts survive retries. |
+| Progress stage and next action | `first_delivery.ts` → status/quota/Chat | Derive from receipts and Todo facts; do not persist another pending-state authority. |
+
+Decision capture, work read evidence and direction read evidence refer to the
+same original work without becoming interchangeable. Reuse the existing capture
+lineage; proposals for unified capture or receipt-to-continuation composition
+must not be assumed to be shipped APIs. Original-Turn recovery remains separate
+from choosing subsequent work. No v0/v1/v2 producer is retired merely because its
+historical reader remains available.

+# Freshness 评测报告：常规场景与目标变更场景
+
+本报告合并两个场景中已选定的 main 与修复后 freshness 数据，只使用各次运行的原生评分与原始用量账本。它是一次诊断结果汇总，不是正式榜单成绩、重复实验结论或 freshness 单一机制的因果证明。
+
+**目标变更场景中，修复后 freshness 更早发现并采用新需求，原始分数较高；常规场景中，main 原始分数较高。两次 freshness 最终都异常退出，因此质量表现与运行可靠性必须分开判断。**
+
+English summary: This report combines one unchanged-task diagnostic comparison
+and one silent goal-change comparison. The repaired freshness snapshot has a
+higher original score in the goal-change scenario and a lower original score
+in the unchanged-task scenario. Both treatment runs remain `runner_invalid`.
+All four runs remain unqualified for countable score claims. Different complete
+source snapshots, a historical target baseline, single attempts, incomplete
+economic cost and evaluator sensitivity limit attribution. No aggregate win
+rate, leaderboard result or general superiority claim is made.
+
+## 1. 范围、版本与测量口径
+
+| 条件 | main | 修复后 freshness |
+| --- | --- | --- |
+| 产品源码 | `9c9b5f5555beafb7ec7d6984b18e1fcfb63be292` | `a49afcd6c6e881d85592d5542d3fa4873ace8647` |
+| 共同 runner 源码 | `c5cd8abb4883f021755e99a2c40a27a7b979b93a` | 相同 |
+| 模型 / 推理设置 | `gpt-6.1-sol` / `high` | 相同 |
+| 执行路径 | LoopX `heartbeat-resume` | 相同 |
+| 单次原生预算上限 | 7,200 秒 | 相同 |
+| 自动评测间隔 / 提交冷却 | 1,800 秒 / 216 秒 | 相同 |
+| 原生评分 | 五阶段通过率按 2 / 2 / 3 / 2 / 1 加权 | 相同 |
+| 工作 / 评分资源上限 | 4 CPU、16 GiB / 4 CPU、8 GiB | 相同 |
+| 合成凭据规则提醒 | 相同的已批准占位符提醒 | 相同；扫描策略未放宽 |
+
+main 也是 LoopX 产品快照，并非裸模型基线。两个产品快照包含多项差异，不能把全部分差归因于 freshness 检查。两小时是这次比较的预算上限，不代表完成了原官方十二小时评测。
+
+**分支与受测源码的关系：** 本报告的 freshness 受测文件树为
+`a49afcd6c`。PR #5677 分支随后 rebase 到更新的 main，并修复恢复和验证问题；
+报告与入口链接也是评测后增加的文档。本文仍只记录这四次历史运行，
+不代表对 rebase 后源码重新运行了评测，也不证明新版本有相同分数或已达到合并条件。
+
+每个场景各保留一次 main 与一次修复后 freshness 结果。目标场景的 main
+是已存在的参照运行，修复后仅重新运行了 freshness；常规场景则串行运行
+main、freshness 各一次。两场景都不是重复采样；目标场景尤其不构成同步
+重跑的严格配对。本文不展示修复前 freshness 的结果，也不把这四次运行
+汇总为胜率或总体平均提升。
+
+### 资格独立于原始分数
+
+所有运行均保持 `score_countable=false`、`matched_pair_countable=false`。
+严格运行时隔离，尤其是求解器 shell 与模型提供商凭据的隔离，没有获得
+完整见证；原生反馈传输等资格也未因此补齐。有效的原生评分报告只证明
+某次提交被原评分器评分，不代表求解运行有效、需求全部验收通过或结果
+可进入正式榜单。两次 freshness 均保留 `runner_invalid`，不改写成成功。
+
+## 2. 两场景结果总览
+
+以下分数都是原生最佳及最新提交的分数；本表四次运行的最佳与最新分数分别相同。
+
+| 场景 | 指标 | main | 修复后 freshness |
+| --- | --- | ---: | ---: |
+| 目标变更 | 原始分数 | 50.1548% | 71.5833% |
+| 目标变更 | 总 token | 48,614,137 | 46,728,979 |
+| 目标变更 | 未缓存输入 token | 683,402 | 580,372 |
+| 目标变更 | 输出 token | 195,055 | 184,063 |
+| 目标变更 | 原生执行时间 | 7,058.702 秒 | 6,855.989 秒 |
+| 目标变更 | 整次进程墙钟 | 7,267.179 秒 | 6,925.531 秒 |
+| 目标变更 | 求解器退出码 | 0 | 2 |
+| 常规原题 | 原始分数 | 76.7262% | 73.1548% |
+| 常规原题 | 总 token | 67,781,522 | 68,961,858 |
+| 常规原题 | 未缓存输入 token | 782,865 | 617,460 |
+| 常规原题 | 输出 token | 233,729 | 210,510 |
+| 常规原题 | 原生执行时间 | 7,058.972 秒 | 7,058.968 秒 |
+| 常规原题 | 整次进程墙钟 | 7,142.429 秒 | 7,135.510 秒 |
+| 常规原题 | 求解器退出码 | 0 | 2 |
+
+目标变更场景的 freshness 原始分数高 **21.4285 个百分点**，总 token 少
+约 **3.88%**。常规场景的 freshness 原始分数低 **3.5714 个百分点**，
+总 token 多约 **1.74%**，但未缓存输入少约 **21.13%**、输出少约
+**9.93%**。这些是选定样本的观察差异，不是统计显著性或货币收益。
+
+## 3. 目标场景：运行中静默替换完整需求
+
+最初任务是离线 OpenAPI 兼容性比较接口与命令行工具；约第 900 秒，
+受保护的权威需求文档静默替换为报告基础设施、校验后 hook、pytest
+集成、示例生成与格式/覆盖控制五个目标。两边都要自行读取变化并调整工作。
+评分器始终按照最终需求评分；需求变化前的提交也使用同一评分器。
+实际发布延迟分别为 901.005 秒与 901.370 秒。
+
+### 3.1 原生质量与阶段进展
+
+| 原评分阶段 | main | 修复后 freshness | 权重 |
+| --- | ---: | ---: | ---: |
+| Hooks | 11/12 | 11/12 | 2 |
+| Report writers | 13/14 | 14/14 | 2 |
+| Pytest reporting | 3/8 | 3/8 | 3 |
+| Examples | 0/11 | 9/9 | 2 |
+| Email / body generation | 2/10 | 2/10 | 1 |
+
+Examples 的分母按原报告保留，不把它当成完全相同的逐检查集合直接相减。
+总体比较沿用原生加权分数。freshness 的主要新增交付是 writers 与
+examples；hooks、pytest 和 generation 仍有缺口。完整通过阶段数分别
+为 0/5、2/5，它们不是总体质量分数，也不能被本地测试通过数替代。
+
+| 自动评测捕获时间附近 | main | 修复后 freshness |
+| --- | ---: | ---: |
+| 30 分钟 | 0.020000 | 0.203333 |
+| 60 分钟 | 0.203333 | 0.360476 |
+| 90 分钟 | 0.464048 | 0.515833 |
+| 原始最佳 / 最新 | 0.501548 | 0.715833 |
+
+这些是原自动评分样本，没有插值或追加评分。freshness 在共同时间窗口
+已有较高分数，但其 0.715833 只观察到一次，不能宣称稳定重复达到。
+由于提前退出，freshness 没有 120 分钟样本。主动/自动评分数分别为
+main 5/3、freshness 7/3，共 18 份原生评分报告。
+
+两边最终归档的完整字节与最后一次主动提交不同；逐文件核验支持主要
+源码、测试、文档及配置相同，freshness 核对范围为 1,320 个文件。
+没有给最终归档追加评分，因此分数仍属于原始提交。
+
+### 3.2 从读取变化到实际采用
+
+以下时间均从新需求发布开始计算：
+
+| 行为 | main | 修复后 freshness |
+| --- | ---: | ---: |
+| 首次完整读取新需求 | 958.439 秒 | 45.559 秒 |
+| 首次明确确认需求变化 | 985.457 秒 | 44.588 秒 |
+| 首次成功修改新需求源码 | 1,707.271 秒 | 638.543 秒 |
+| 后续实际实施模块 | hooks、writers、pytest | hooks、writers、pytest、examples |
+
+freshness 在 22.288 秒时已从普通交付结果上下文接触新需求标题，随后
+确认变化，再完整读取文档，所以确认略早于完整读取。两侧均未观察到
+`provider_revision_mismatch` 返回，不能把提前感知解释成一次过期依据硬拒绝。
+
+旧任务被替换时，freshness 保留了原 Turn 的身份；原轮次的结果、方向
+与额度结算完成后，才进入新的实施任务。随后多个模块产生源码、验证与
+原生评分。这支持本次真实运行走通了原轮次结算和后续采用，不能只凭
+新建任务或写出重规划记录宣称成功。最终评分缺口仍然保留。
+
+main 保留已有初始任务实现后推进新需求；freshness 将初始候选保留为
+独立检查点，再恢复原源码推进新需求。初始实现本身不满足新需求，但
+通用探测经验可能复用；不能把变化前全部 token 等同于浪费。
+
+### 3.3 终态失败
+
+main 共 10 条宿主回执，包含一次模型容量不足和尾端超时，之后仍继续
+推进并最终退出 0。退出 0 不表示全部新需求通过验收。
+
+freshness 共 9 条宿主回执，其中三次失败均已调用宿主、退出 1，且未
+标记超时；明确错误是模型容量不足。最后一次发生在自主重规划阶段，
+原操作效果无法确定，外部调度 worker 为避免重复执行而保留
+`replan_outcome_unknown`，最终求解器退出 2。此时距原生上限尚余
+344.011 秒，因此这次目标场景的停止原因是容量错误与未知结果恢复边界，
+不能归为预算耗尽。两侧都未观察到合成凭据造成的宿主调用前拒绝。
+
+## 4. 常规场景：完整原题始终不变
+
+完整报告与校验增强任务从首次指令保持到终态；没有初始替代任务、定时
+发布器或中途需求编辑。main 后 freshness 串行各跑一次。两次求解和
+原生评分均已终态，分别产生 10 份与 12 份原生评分报告，共 22 份。
+
+### 4.1 原生质量
+
+| 原评分阶段 | main | 修复后 freshness | 权重 |
+| --- | ---: | ---: | ---: |
+| Hooks | 11/12 | 11/12 | 2 |
+| Report writers | 12/14 | 13/14 | 2 |
+| Pytest reporting | 3/8 | 3/8 | 3 |
+| Examples | 9/9 | 9/9 | 2 |
+| Email / body generation | 10/10 | 5/10 | 1 |
+
+freshness 在 writers 多过一项，在最后阶段少过五项。两边最佳与最新
+源树不同，但最新原始评分的生产源码与最终归档逐文件一致；没有把未评分
+的最终代码当成额外提升。main 完整通过 2/5 阶段，freshness 为 1/5；
+这些阶段完成比例不是 76.7262% / 73.1548% 的加权分数。
+
+终态后的源码与既有静态检查语义比对提示：两边都实现了邮箱域名转小写，
+但内部辅助函数命名不同，部分隐藏检查对该名字敏感；五项失分与这个差异
+吻合。因此不能直接把五项失分描述为五项业务功能没做。该解释仍是静态
+推断，缺少本次逐检查错误日志的直接确认；原始分数没有修改，也没有重跑
+评分器。公开报告不包含隐藏检查实现、函数名或原始评分输出。
+
+### 4.2 实际推进与未完成结算
+
+freshness 在启动后有实际任务完成与后续模块实施，不是仅接通启动；
+但这些过程事实不证明质量收益。原题没有变化，本场景也没有提供测量
+“发现需求变化并正确采用”的机会。
+
+连续六轮工作后触发周期性重规划。模型发现报告配置从 True 更新到
+False 的问题，形成验证记录和后续方向；发现问题不等于已经修复。
+重规划写回成功，但返回仍要求登记本轮额度消耗并完成结算。约四秒后
+宿主超时，退出码 124；轨迹和持久事件未见对应结算完成。
+
+调度器保留了“该重规划已启动”，但自己的记录没有完整原轮次结算身份；
+模型后来补齐的身份没有同步回调度器记录。恢复代码只处理带完整身份的
+记录，因此跳过了这次恢复。防重复保护随后阻止用新轮次重做未知操作，
+以 `replan_outcome_unknown` 停止，求解器退出 2。源码中的预算收尾
+预留与模型临近截止才写回共同形成时间窗口；实际恢复仍有缺口。
+这不是已经自动恢复成功，也不是一次需求版本过期拒绝。
+
+main 末尾也有宿主超时，但后继预算耗尽唤醒未调用宿主，worker 最终
+退出 0。常规场景的 freshness 运行状态保持无效；其原始评分仍可作为
+这次提交的诊断观察，不能因此升级为有效运行。
+
+## 5. 完整可得模型用量与成本边界
+
+用量以响应 ID 去重，包含规划和后续宿主轮次；不重复计入镜像会话文件。
+各运行增量账本与末次累计账本核对一致。缓存输入是输入的子集，推理
+输出是输出的子集，不能再次相加。
+
+| 用量 | 目标 main | 目标 freshness | 常规 main | 常规 freshness |
+| --- | ---: | ---: | ---: | ---: |
+| 输入 token，含缓存 | 48,419,082 | 46,544,916 | 67,547,793 | 68,751,348 |
+| 缓存输入 token | 47,735,680 | 45,964,544 | 66,764,928 | 68,133,888 |
+| 未缓存输入 token | 683,402 | 580,372 | 782,865 | 617,460 |
+| 输出 token，含推理 | 195,055 | 184,063 | 233,729 | 210,510 |
+| 推理输出，已含于输出 | 88,608 | 80,361 | 117,809 | 110,910 |
+| 总 token | 48,614,137 | 46,728,979 | 67,781,522 | 68,961,858 |
+| 去重响应数 | 272 | 274 | 422 | 378 |
+| 原 judge 服务耗时之和 | 1,645.150 秒 | 575.725 秒 | 123.665 秒 | 251.967 秒 |
+
+目标场景的末次旧式 token 快照比响应账本分别少 355,410、357,766；
+常规场景也存在快照口径差异。本报告使用已经核对连续性与累计值的去重
+响应账本，不混用旧快照。
+
+judge 耗时与求解及进程运行重叠，不能直接加到墙钟上。进程减原生耗时
+包含准备、归档、排空和清理，不能全部算作控制平面开销。目标 freshness
+墙钟少约 4.70%，其中含提前失败，不能全部解释为提速；常规墙钟差约
+6.919 秒，也不足以证明性能提升。
+
+**完整经济成本仍未知。** 操作者模型用量和注意力、未报告的失败请求
+费用、judge 模型成本、共享准备和审查 CPU/墙钟、闲置与能耗，以及实际
+计费价格没有完整记录。未知项没有按零处理。大量输入命中缓存，因此
+总 token 增减也不能直接推导到账单增减。
+
+## 6. 结论、验证与后续边界
+
+- 目标变更场景支持这次样本中更早读取、确认与实际采用新需求，以及较高
+  原始质量分数；它没有证明正式有效成绩或稳定可靠续行。
+- 常规场景中 main 原始分数较高；freshness writers 略多通过、未缓存输入
+  和输出较少，但总 token 略多，且末轮结算失败。命名敏感检查限制了分差
+  的功能解释。
+- 两次 freshness 的停止触发不同：目标场景是模型容量错误，常规场景是
+  宿主超时；两者都暴露未知重规划效果的恢复边界，不应混成同一故障原因。
+- 单次样本、历史参照、不同完整源码快照、串行时序、未资格隔离及未知
+  完整费用，都限制因果和经济结论。不发布跨场景总体胜负或普遍收益。
+- 质量、持续控制、完整结算和运行有效性分别核对；保留失败及未测区别，
+  不以进程退出码、任务数量、测试通过数或记录写回替代需求验收。
+
+本报告复用终态后的原始评分、源码核验和响应账本分析。目标场景 18 份、
+常规场景 22 份原生评分均保留原值；没有启动新求解、替补运行或额外 judge。
+公开内容仅含经整理的汇总数字、通用机制观察与源码版本，不含原始任务、
+私有运行标识、会话、凭据、隐藏检查或机器路径。私有证据保留用于授权
+审计；本文不是第三方可独立重放的公开实验包。
+
+后续修复应让调度器在启动重规划前持久化完整结算身份，并在原身份下
+恢复尚未完成的步骤，同时给临近截止的重规划留下收尾时间。还需分别
+确认评分接口的兼容性、当前默认产品入口的采用和重复运行表现。这些是
+当前证据指出的待验证方向，本次整合没有把它们记为已修复或已通过。

 | `premerge_binary_visual_coverage` | A first-screen PNG makes premerge fail with invalid UTF-8, although its text checks are clean. | Exact changed paths, text scan coverage, raster evidence and the existing exact-head review boundary. | The premerge adapter feeds binary images into a text-only scan and loses the distinction between text readability and visual privacy. | Keep the text scanner unchanged; explicitly list changed images as outside text coverage and retain the existing manual-review hold, including image-only changes. Unknown binary/text decode failures remain failures. Inspect pixels, metadata and provenance in the ordinary exact-head review; never silently skip images, certify them with a text pass, add a bypass flag or demand another user presentation approval. |
 | `planning_visibility_requires_declared_complexity` | A flat runnable backlog hides the Goal or broader work view because no dependency, blocked work or acceptance gap has been registered. | Same-source default/opt-out planning packets, original Goal, bounded work summary, omission counts and full-read routes. | A supplemental-context condition is mistaken for evidence that no strategic planning is needed; byte reduction removes useful visibility. | Show Goal and bounded work context by default at applicable preselection boundaries, including flat backlogs. Preserve omission counts, complete-read routes and action authority. Reduce exact duplication instead of hiding work; qualify input-cost changes with matched fixtures and keep model benefit unproven until measured. |
 | `stale_objective_repeated_as_current` | Current planning repeatedly projects an obsolete objective despite newer direct user direction. | Recorded source versus owner-applied objective revision, current canonical basis and each peer's adoption. | Fresh file bytes are mistaken for current intent; a registry/display edit cannot establish peer adoption. | Prepare an evidence-linked operating-objective revision through the existing Goal update surface. Preserve original commitments and use owner apply. Reconcile each peer's work and record its own exact adoption before new execution; do not revise for ordinary progress/diagnostics/age, impersonate peers, or interrupt in-flight settlement. Reuse a pending proposal; adoption is once per objective revision, not per Turn or peer/work write. Verify native tool invocation, current projection and stale-execution refusal, not only serializer output. |
+| `owner_requirement_misclassified_as_projection_corruption` | An Agent sees changed owner requirements beside stale derived Todos, searches for projection overwrites or stale goal prose, then restores an older plan into the current owner document. | Current registered primary documents, original read basis, exact document write, projection-only scope and later reread. | A legitimate requirement change was treated as projection corruption; old Agent plans were incorrectly promoted into owner authority. | Preserve the current owner source and revise derived work. Freshness binds separately registered goal_doc content as the primary prose through the final provider check. Never reconstruct an existing requirement from a prior read; missing or conflicting owner sources require verified recovery or owner resolution. Hosts enforce document and parent-directory write isolation. |
 | `history_artifact_observation_failure` | History or status readback fails with `ENAMETOOLONG`, permission denial or an I/O error while checking a recorded artifact path. | Synthetic index row, failing filesystem observation, retained Run evidence, index digest and next-read recovery. | A derived artifact availability lookup propagates an OS error and hides otherwise readable durable history on older Python versions. | Isolate filesystem lookup errors in the shared artifact observer; report availability as unconfirmed through the existing false flag, retain Run evidence and retry on the next read. Do not suppress errors reading the index itself or rewrite evidence. Cover real history/status CLI readback with File and SQLite fixtures. |
 | `status_cache_decode_failure` | Opt-in cached status or quota readback fails with a UTF-8 decoding error while live collection works. | Cache miss metadata and a disposable malformed-cache reproduction through both CLI consumers. | The shared cache reader handles JSON and filesystem errors but lets text decoding abort live fallback. | Classify invalid UTF-8 as an unreadable cache miss in the existing IO owner; preserve damaged bytes on reads, collect live facts, and rewrite only with the explicit cache-write option. Test current Todo selection and successful reuse after repair; never suppress canonical source failures. |
 | `lock_holder_decode_hides_timeout` | Lock diagnostics or a contended acquisition raises `UnicodeDecodeError` instead of reporting unreadable metadata or the typed timeout. | Synthetic damaged holder bytes, liveness readback, and a real held-lock timeout followed by normal reacquisition. | Holder text decoding fails before the JSON/error guard, masking advisory failure and incident recording. | Treat invalid UTF-8 as unreadable at the shared holder reader; retain valid alternate records and kernel ownership. Cover the incident, inspection guidance and recovery after the actual holder exits; never delete the lock as repair. |
