 This candidate does not close those qualification gates.
 
+**Prospective V10 rendering qualification (2026-11-09).**
+The original all-samples 1-second gate remains the criterion for its historical
+results. Subsequent loaded-lens qualification repeats each of the same five
+directed transitions three times on the complete 200-item fixture, starting each
+repeat on Board. Every transition's median must be below 1 second; every sample
+must be below the existing 2-second page-usability ceiling. Three repetitions
+are the smallest odd sample count that separates one moderate outlier from a
+repeated slowdown. Report all 15 click-to-visible samples, the five medians,
+maximum and count above the 1-second target before asserting the budget.
+Playwright action waiting and browser scheduling are included; this is local
+rendering qualification, not pure backend latency or a kernel regression verdict.
+The bounded isolated-overage allowance applies to both a real page delay and
+host scheduling overhead; a median cannot identify their cause. Browser long-task
+entries are reported alongside each measured window when supported, with an
+explicit unavailable signal otherwise. They are diagnostic evidence, not proof
+that an unexplained Linux overrun was host noise. A single real page stall below
+2 seconds may pass this prospective rule; the above-target sample remains visible.
+Every lens retains all 200 items, and classification, selection, no-effect and
+error checks remain independent of timing. Initial rendering and expansion retain
+their existing 2-second checks. Historical failures are not reclassified by this
+rule; cross-host, installed, live-team, full-cost and unrelated CI qualification
+still require their own evidence.

 ### Recovering a native result after Core failure
 
+A native terminal error remains a failure. When the complete current invocation
+is idle, every observed step is settled and its final error is done, the adapter
+retires that invocation's cancellation target before returning the structured
+error. Active or unknown steps retain existing bounded cancellation and permission
+handling. Avoiding a second cancellation neither proves effect-free execution
+nor grants replay, recovery, result adoption or business-completion authority.

 may reserve one new quota-continuation Turn only after two independent reads of
 the same idle native trajectory prove its latest invocation contains exactly the

Subject: [PATCH 25/40] fix(quota): reject rolled clocks on blocked retry
 closeout (#8371)

Date.parse accepted impossible calendars and offset-less timestamps as a
1-30 minute retry, so settlement could close that Turn without a spend.
Qualification now uses the same timezone-aware resume clock as the writer.

 this checkpoint does not authorize merge or declare the minimal kernel complete.
+
+### 2026-11-09 — Reuse validated complete source-basis bytes
+
+The existing Python Todo compatibility transport now retains its validated
+canonical field bytes as the complete source basis. It previously encoded each
+field twice, once for the basis and once for digest validation. The basis is
+only decoded as JSON; mapping insertion order is not a source difference. Full
+digest mismatch fallback, scalar-fact protection, request-scope provenance and
+source/revision/lease/refusal/replay guards remain. No decoder, cache, provider,
+configuration, protocol or competing decision owner is added.
+
+On the same real isolated SQLite field observation, the immutable original
+encodes two fields four times and the candidate twice; both retain complete
+values and empty source differences. The original passes two mapping-order and
+scalar-protection characterization cases; the candidate passes all nine canonical
+source cases across File/SQLite. Final `summary_item.py` SHA-256 `a8ca890eee547929060ac326fc8b85ca9c14a8fd5ec850deb2fe3e6586628513`
+matches the isolated wheel. Four complete 101-Todo source/wheel × File/SQLite
+CLI lifecycles preserve sum45, original completion time, four receipts, one debit,
+restart and refusal/replay, with two normal native exits per lifecycle.
+Validation uses macOS arm64, CPython3.13.5 and Node22.22.3.
+
+This is an encoding mechanism refinement, not matched-cost or full marginal-cost
+and adoption qualification. Frozen cost, attribution and normal-bytecode
+campaigns remain unchanged. PostgreSQL host factory absence is already recorded;
+its store/service checks do not qualify a source/wheel host journey. Retain every
+original acceptance and I3/minor-release, M1/#8011, full R0/V10/R1, D2/D5/D6/D3,
+context/model/split-install, installed-host, full-cost/adoption and historical
+failure gap. Exact-head review, CI/readiness and maintainer merge authority remain
+separate gates.

+保留 sum45、原完成时间、四份 receipt、一次 debit、restart 和 refusal/replay，
+每条均观测两次正常 native exit。验证环境为 macOS arm64、CPython3.13.5、Node22.22.3。
+
+这是编码机制细化，不代表 matched-cost、完整边际成本或 adoption 资格。冻结的 cost、
+attribution 与 normal-bytecode campaign 保持不变。PostgreSQL host factory 缺失
+已有记录，其 store/service 验证不能成为 source/wheel host journey 资格。继续保留

Subject: [PATCH 27/40] Remove dead personal-workspace i18n keys and the unused
 ManagerBrief operations prop (#8414)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Delete 57 workspace i18n message keys (114 lines, en + zh-CN) that no
longer have any reference: composer hint/placeholder text replaced by the
inline composer placeholder, the retired header description/theme/agent
labels, and leftover drawer/tasks/conversation/sidebar/palette-adjacent
copy. Keys composed at runtime (palette.*, goal.*, actionReview.*,
capabilities.*, runs.*, time.*) were verified as live and kept; the scan
covered quoted literals plus template/concatenation construction across
src, smoke and i18n-internal localization helpers, and tsc confirms the
WorkspaceMessageKey union stays consistent in both dictionaries.

Also drop onViewAllOperations, which personal-workspace-page threaded
through ManagerHomeBoard into ManagerBrief where it was declared but
never read.

Validation: tsc --noEmit clean; smoke:usage-progress (asserts i18n
source spelling), smoke:home-route, smoke:conversation-input and the
personal-workspace contract tests pass; the personal-workspace smoke
suite passes its node/SSR steps and the browser lane passes 37/38
scenarios — research-worker-readback fails with route.fetch ECONNRESET
reproducibly on pristine origin/main in the same fresh-worktree
environment, so it is a pre-existing environment gap, not a regression
from this change. No rendered output changes; removed strings were
unreachable.

+### 8.7 Budgeted research planning on EdgeBench
+
+**Hypothesis.** Comparing bounded multi-step continuations by their expected
+accepted outcome at the remaining horizon can improve native results over the
+current LoopX policy. This includes prerequisite work, informative measurements
+and time for confirmation, not just the next action's immediate score gain.
+[Joint decisions §5.8](target-yardstick-stride-decisions-v0.md#budgeted-planning)
+owns the decision semantics; §5.9 owns the subsequent calibration/learning path.
+This is a proposed experiment, not a completed run or established benefit.
+
+#### First implementation slice
+
+Use the existing single-agent Stride/Yardstick/Explore path. A revision-pinned
+benchmark treatment adds the §5.8 comparison to the current decision instructions:
+compare the supported continuation with a small number of plausible routes,
+identify dependencies and a discriminating next boundary, then execute the first
+coherent slice. Keep evidence and predictions in existing findings/plan reasoning;
+use supported `next_probe` and Yardstick fields for the immediate choice. Do not
+add unsupported v0 fields, a required extra model call or a per-Turn form.
+
+The first implementation PR should contain the bounded instruction change, its
+explicit treatment selection in the existing benchmark configuration/manifest,
+and one real-path readback/followthrough episode showing the model's next work.
+Keep default behavior unchanged. Pin the exact policy, source and projection used;
+existing detail reads suffice if a richer projection is not yet merged. Source
+delivery and model adoption qualify the path, not effectiveness. A dual-session
+Controller/Worker runtime, numerical fidelity engine and learned policy are not
+prerequisites. Later schema work needs an observed missing producer/consumer fact.
+
+#### Affordable conditional-effect pilot
+
+Start with three complementary task types, under the pinned upstream task names:
+
+| Task | Mechanism to investigate |
+| --- | --- |
+| ANN vector search | Investment in a different search mechanism can require several steps before a native gain. |
+| Ad placement | Local ranking can disagree with native outcomes; more local samples alone need not remove bias. |
+| Grid optimization | A better average can still violate a hard correctness or tail-time constraint. |
+
+These are hypotheses for the panel, not new empirical claims. Compare two arms:
+**current LoopX policy** and **the same path plus budgeted planning**. Both receive
+the same available evidence, resource facts, model/tools, feedback and acceptance
+rules; freeze context projection, starting candidate, contention policy and source
+revision. Changed reasoning is the treatment and its overhead counts. Do not
+quietly give only the planning arm a repaired proxy or extra native evaluations.
+
+A bounded starting design is **3 tasks × 2 independently generated, prospectively
+selected checkpoints × 2 arms × 3 hours = 36 additional worker-hours**. Report
+checkpoint creation, control and evaluation costs as well. The two source runs
+per task, checkpoint rule and assignment are selected before outcomes; do not
+choose favorable peaks. This small pilot screens mechanisms, not statistical
+sufficiency for a general gain claim. Freeze its resource ceilings before launch.
+
+Use the existing [matched-continuation boundary](hierarchical-agent-stride-control-v0.md#matched-research-continuation):
+a copied workspace alone is not a shared research state. Candidate/frontier,
+accepted incumbent, evidence, memory, pending results, available budget and native
+submission history/cooldown must be equivalently reconstructable, with fresh run
+identities and inherited immutable provenance. Prefer quiescent checkpoints to
+reduce ambiguity. The [adapter](../../../benchmark/edgebench/README.md) currently
+does not guarantee native judge restart/cooldown continuity; prove the required
+restore seam before admitting a pair. If unavailable, use a matched from-start
+comparison and report its actual budget rather than label a fresh registration
+as a checkpoint fork. This does not require building a general replay platform.
+
+Keep native cooldown and terminal selection unchanged. If three hours cannot
+accommodate a useful multi-step route and permitted confirmation, classify the
+pilot as uninformative and redesign its next preregistered horizon; do not loosen
+cooldown or add retroactive evaluation slots. Each valid pair estimates the
+conditional effect from that checkpoint over three hours. It does not establish
+the effect of running the policy from scratch for eighteen hours.
+
+#### Full-budget benefit and later refinement
+
+After a useful pilot, compare **strong Official continuation, current LoopX, and
+the selected planning treatment from the start**, with matched task/model/seed
+blocks and an eighteen-hour budget per run. Freeze repeat count, resource caps,
+practically meaningful improvement/non-inferiority margins, terminal selection
+and analysis before collecting confirmatory outcomes. Retain the required §5
+baseline evidence; the focused pilot does not replace that evidence program.
+Report 6/12/18-hour curves with the eighteen-hour native outcome primary; keep
+first-submit/startup advantages distinct from sustained continuation benefit.
+An early lag can precede a later gain, but hindsight does not qualify persistence.
+
+Use the native accepted outcome and frozen best/final rule, not the highest local
+score or an untested final workspace. Preserve correctness failures, unfinished
+grading, cancellations and missing coverage with their declared treatment. Bind
+each result to the exact candidate, evaluator/input and submission. Report paired
+effects and uncertainty, time to accepted improvement, complete tokens/wall time,
+control and evaluator cost. Do not sum raw QPS and unrelated task scores; use
+per-task effects and only the benchmark's declared normalization for aggregates.
+
+Read pre-action predictions against realized method, resources, intermediate
+evidence and terminal outcome. Distinguish predicted value, actual adoption,
+information and confirmed gain. Attribute delayed gains to the relevant sequence
+for analysis, not automatically to its last action; observational associations
+remain non-causal. Only then add an affordable lookahead-depth or calibration
+ablation where a specific uncertainty justifies it, rather than a full factorial
+matrix upfront.
+
+Expand when repeated terminal benefits meet frozen margins and uncertainty
+requirements without unacceptable correctness, resource or authority regressions.
+Keep negative and inconclusive results. Freeze the selected policy before testing
+held-out tasks and workloads; adaptively queried native feedback is development
+evidence. Calibrated forecasts and learned allocation must beat the qualified
+current-model policy under the same complete budget. Benchmark evidence alone
+does not authorize production promotion or reuse of raw task data for training.

+
+| 任务 | 要研究的机制 |
+| --- | --- |
+| ANN 向量搜索 | 投入不同搜索机制可能经过多步才产生 native 增益。 |
+| Ad placement | 本地排序可能与 native 结果冲突；增加本地样本未必消除偏差。 |
+| Grid 优化 | 均值更好仍可能违反硬正确性或尾部耗时约束。 |
+

+不足以单独支持一般性收益结论；启动前冻结资源上限。

+将 pilot 标为信息不足，为下一次预注册实验调整时长，不放宽 cooldown 或事后增加
+评测机会。有效配对只估计该 checkpoint 后三小时的条件效应，不能证明从头运行
+十八小时的策略效应。
+
+#### 完整预算收益与后续细化
+
+pilot 有用后，从头比较**强 Official 接续、当前 LoopX、选中的规划 treatment**，
+按 task/model/seed 匹配，单次预算十八小时。确认性结果采集前冻结重复次数、资源
+上限、具有实际意义的改善/非劣效界限、终局选择和分析方法。保留第 5 节要求的基线
+证据；局部 pilot 不能替代完整证据计划。报告 6/12/18 小时曲线，以十八小时 native
+结果为主；首提/启动优势与持续接续收益分开。早期落后可能换来后期提升，但事后
+看到突破不能证明当时坚持合理。
+

+workspace。按预先声明的处理保留正确性失败、未完成评分、取消与覆盖缺失。每项
+结果绑定精确候选、evaluator/input 和提交身份。报告配对效应与不确定性、首次验收
+改善时间、完整 token/墙钟时间、控制及评测成本。不把原始 QPS 和无关任务分数相加；
+报告分任务效应，聚合只用 benchmark 声明的归一化规则。
+
+把行动前预测与真实方法、资源、中间证据及终局结果对照，区分预测价值、实际采用、
+信息与确认收益。分析延迟收益时关联相关工作序列，不自动只归给最后一步；观察关联
+仍不是因果结论。只有具体疑问值得时，再增加可负担的 lookahead 深度或校准消融，
+不一开始铺开全因子矩阵。
+
+重复终局收益达到冻结的界限与不确定性要求，且无不可接受的正确性、资源或权限
+回归，才扩大实验。保留负结果及不确定结果。冻结选中策略后再测 held-out 任务和
+工作负载；被自适应查询的 native 反馈属于开发证据。校准预测和学习型分配必须在

+<a id="budgeted-planning"></a>
+
+### 5.8 Budgeted multi-step research planning
+
+This extends the existing pair/Stride decision, not the work-graph or scheduler
+owner. The near-term caller is the EdgeBench policy experiment in
+[Research program §8.7](long-horizon-harness-benchmark-research-program-v0.md#edgebench-budgeted-planning).
+A plan is a revisable continuation through useful evidence boundaries, not a
+promise to execute every step or a new mandatory record per tool call.
+
+#### Objective and remaining resources
+
+For a fixed starting research state `s0`, let `Y_B` be the accepted native outcome
+under the frozen selection rule at resource horizon `B`, expressed in the declared
+better-is-higher direction (for example, negate lower-is-better step counts).
+This changes notation, not native acceptance or cross-task aggregation. Compare
+policies by:
+
+$$
+J_\pi(B\mid s_0)=\mathbb E[Y_B^\pi\mid s_0],\qquad
+\Delta J(B\mid s_0)=\mathbb E[Y_B^\pi-Y_B^{\pi_0}\mid s_0].
+$$
+
+Within-run gain over the starting candidate is not the incremental benefit over
+an improving baseline. A common starting value cancels without requiring a
+precise absolute estimate, but equal scores do not imply equal research states.
+Respect whether the contract selects the best valid evaluated submission, a final
+artifact, or another outcome; an untested best candidate is not a realized result.
+
+`B` may constrain wall time, tokens and evaluator resources separately. Read
+remaining amounts and availability from their existing owners, retaining coverage
+and unknowns. Same wall time is not same token use. Charge planning, source reads,
+failed work, proxy construction/repair and confirmation to their real resources;
+account for parallel work and waiting without summing overlapping wall intervals.
+Under a fixed-resource terminal-outcome objective, opportunity cost is the work
+foregone. Do not subtract tokens from a score or debit that opportunity a second
+time. A monetary penalty needs an explicit utility conversion and objective.
+
+A simplified planning model with known positive resource use `k(a)` is:
+
+$$
+V^*(s,b)=\max\left\{G(s),\ \max_{a:\,k(a)\le b}
+\mathbb E[V^*(S',b-k(a))\mid s,a]\right\}.
+$$
+
+`G` is the value of ending research under the accepted selection rule. State
+includes incumbent/frontier evidence, unresolved prerequisites, yardstick scope,
+pending results and remaining resources. Real durations may be uncertain and
+availability constrained; the model explains the objective, not a kernel solver.
+Stopping a branch reallocates resources. Ending the entire run has no automatic
+saving benefit if unused budget has no other value; preserve existing honest
+success, exhaustion, authority and resource stop conditions rather than inventing
+an endless-work obligation or a fixed-cost Bernoulli stopping threshold.
+
+#### Compare continuations, execute a bounded first slice
+
+Use the current route as a comparator and expand only decision-relevant
+alternatives. Their value depends on competing routes and the remaining horizon,
+not a fixed index of each candidate alone. Immediate gain/cost is a screening
+heuristic: prerequisite work, complementary evidence and delayed improvements can
+make it rank plans incorrectly. A zero-gain first probe does not refute a useful
+multi-step plan; a past late breakthrough does not justify arbitrary persistence.
+
+The decision should make these meanings recoverable from existing work/evidence:
+
+| Meaning | Minimum useful content |
+| --- | --- |
+| Comparison | Current accepted objective, incumbent/frontier and the continuation being compared; same-state/budget scope. |
+| Continuation | Necessary dependencies and a short conditional route to an informative or accepted result; what survives a failed branch. |
+| Prediction | Possible outcomes, goal-relevant gain or range, resource/time range, evidence basis and material unknowns. |
+| Next boundary | A feasible first slice, distinguishing observation, condition to continue/revise/stop, and time/resources needed for confirmation. |
+
+These are planning semantics, not four new wire fields or a form to repeat.
+Use Stride's existing plan/reason axes and `next_probe`, the ordinary Yardstick
+`next_action`, and cited Explore findings for supporting reasoning. Keep the
+current cue short (§5.7); do not squeeze a full plan into bounded `cost_bound`
+text or add unsupported keys to v0. A real new deliverable/dependency uses Todo's
+existing owner. A plan step within the same deliverable does not create a Todo.
+Execute the first coherent slice and reconsider at useful evidence boundaries;
+retain normal settlement and due reviews without forcing a method switch.
+
+For example, compare continuing a supported implementation with establishing a
+necessary correctness check and then trying another mechanism. If the check
+fails, revise that prerequisite; if it passes, continue while useful budget
+remains; if confirmation will miss the deadline, compare the feasible validated
+routes. This is a conditional research plan, not a generic enforced tool order.
+
+Estimates come from mechanism/headroom evidence, comparable earlier experiments
+and bounded probes. Allow unknowns, intervals and decision thresholds rather
+than invented precise probabilities. Log predictions before seeing results and
+calibrate them against realized outcomes. A model's confidence or observed
+`grow`/`verify`/`switch` success frequency is not an action's causal value: those
+choices occur in different states. Bellman notation does not supply a transition
+model, and a post-hoc peak must never become a decision-time feature.
+
+#### Progress evidence and measurement choice
+
+Milestones are dependent state predicates with evidence, applicability and
+possible reversals; alternative branches need not satisfy the same milestones.
+Do not model heterogeneous steps as iid Bernoulli trials or add one reward per
+completed step. Keep accepted goal gain, newly satisfied prerequisites and
+information/adoption separate. Flat incumbent score does not by itself prove
+useful learning or regression prevention. For an unchanged scalar outcome rule,
+score differences telescope to final improvement; process reward for a future
+learner must preserve that objective rather than reward activity or repeatedly
+repairing the same defect.
+
+Local evidence has both noise and possible systematic bias. More local samples
+cannot by themselves fix workload mismatch or missed hard correctness/tail-time
+constraints. Qualify a yardstick where choices happen: same-parent candidates,
+exact evaluator/input scope, nearby alternatives and native counterexamples.
+Across-time rank agreement may merely reflect common search progress. Include a
+bounded audit of uncertain/proxy-rejected candidates when it can expose missed
+opportunities; do not let the proxy alone veto informative authorized evaluation.
+A conflict revisits the scoped method, not a global blacklist of its whole type.
+
+Evaluator cooldown, queue availability and pending feedback are planning inputs,
+not permission to change the benchmark. Reuse immutable candidate/result links
+when feedback arrives late. A pending result can support independent work while
+it runs; it is not a measured gain. Confirmation must fit the frozen terminal
+protocol, and adaptively used native feedback is development evidence, not an
+untouched holdout.
+
+### 5.9 Policy evolution through the same owner
+
+| Stage | Useful next result | Retained boundary |
+| --- | --- | --- |
+| Current-model pilot | A revision-pinned bounded planning treatment changes actual work and improves the §8.7 comparison. | Existing Stride/Yardstick/Explore owners and ordinary responses; no second controller session or numerical fidelity engine prerequisite. |
+| Calibrated estimates | Pre-action predictions linked to actual method, duration, next state and terminal result improve forecast/calibration on held-out episodes. | The domain provider owns measurement meaning; supporting estimates are not acceptance, permission or fabricated counterfactual labels. |
+| Learned allocation | A learned policy beats the qualified current-model policy under matched full budgets and transfer tests. | Replace the policy implementation behind the same work decision boundary; Core retains admission, budget, identity and settlement. |
+
+Record state and evidence as they were available at decision time, action and
+actual method, resource use, next observation/state, and later outcomes through
+existing provenance/followthrough. Selected-action logs can train forecasts;
+they do not reveal unchosen outcomes. Use prospective matched continuations or
+explicitly justified off-policy assumptions for policy-value claims. Preserve
+failed, cancelled and unknown results. Raw task data stays within the research
+boundary and cannot become a production memory or training corpus by default.
+
+No new policy registry, plan database, scheduler or universal scalar rank is
+needed for the first caller. Before any later schema change, demonstrate the
+missing producer/consumer fact, extend the existing versioned owner, and qualify
+readback/recovery/off behavior. Controller–Worker composition can later consume
+the same decision; it neither grants additional authority nor proves benefit.

 provider failures, Stop, blocked planning, or a valid terminal LoopX decision.
 Campaign duration coverage must still classify an early exit as missing time.
 
+An operator may explicitly hand off an unchanged stopped legacy heartbeat Host
+whose failed attempt produced no stdout/stderr and returned a phase timeout,
+while the native session remained idle. This is disabled by default. First run
+`benchmark.edgebench.stopped_recovery` with `--idle-host-handoff` and, when
+needed, `--install` to place its inert proof in that same stopped worker. The
+producer requires the exact failed scheduler, pending witness, latest unique
+wake, original workspace, registry, runtime and native stores, including committed
+SQLite WALs. It preserves the unknown failure and does not infer a quota failure
+from diagnostic text. The proof grants no execution or evaluator authority.
+The empty-output witness uses the worker's `stdout.jsonl` and `stderr.log` files;
+the producer and receiver share that writer-owned layout.
+
+After the owner restores compatible native evaluator authority separately,
+restart only the original inert container and retain its original environment.
+Set `LOOPX_INTERRUPTED_SOURCE` to the installed proof and provide an explicitly
+authorized finite `LOOPX_PHASE_DEADLINE_EPOCH`. Invoke
+`python -m benchmark.runtime.scheduler` with its ordinary arguments plus
+`--idle-host-state-sha256 ORIGINAL_SCHEDULER_SHA256`. The consumer verifies the
+same namespace and complete unchanged source, current Goal/session/profile and
+fresh native account allowance. The native history owner must return a stable
+complete history whose last completed cursor precedes the failed attempt, with
+no pending effects. Its observer uses a disposable copy of the native store and
+committed WALs because native read APIs can update their own history index; it
+copies no authentication file. Every copied native base participant must match
+the producer's sealed set; an extra archived-session/index store or database
+version is unsupported and rejected before native observation. The original
+source remains byte-stable. Empty
+output or a session-identity error alone is insufficient.
+The final source comparison runs under current Goal admission. Only its exact
+held cross-runtime lock and holder records may differ, verified through the
+existing lock owner's process/token witnesses; registry contents, SQLite/WALs,
+work files and unrelated lock files remain protected.
+
+An accepted handoff creates a new finite transport phase linked to the original
+failed record. It retains the session, Goal, Todos, work and failure evidence;
+it does not settle an old Turn, refill native opportunities/cooldown, or create
+another task budget. Repeating the exact phase retains its clock and any later
+failure; a changed deadline cannot replay the original handoff. The owner still
+enforces its audited remaining solver allowance and external cutoff, including
+setup and cleanup. Omit both new opt-ins to keep the ordinary refusal path.
+Retain the proof and phase records when disabling future handoffs. Genuine Stop,
+unavailable allowance, changed source or native work during the failed window
+continues to hold execution.

+### 2026-11-08 — Canonical source scalar-comparison refinement
+
+The existing `todo.read` owner now uses exact equality for unchanged primitive
+fields after its complete canonical-field digest and JSON clone. Containers and

+source-lane additions, scalar-fact protections and stale-reference rejection

+belong to different budget decisions, so their repeated read recipes do not
+justify an authority cache. The bounded refactoring stays in the existing
+canonical source comparison instead of collapsing those decisions.
+
+Final `read_transaction.ts` SHA-256 `ac0ae4311e4fe5c385ec75b3569cd8ebbe98328189e2885b5ecdcccb11c476b3`
+passes 61 Python and 56 TypeScript cases plus real isolated PostgreSQL16.15
+store391/service11, zero skips in these qualified runs. The immutable original
+passes the selected native PostgreSQL source-protection case; a mutation that
+treats all primitives as unchanged fails it. Parent replacement, deletion and
+restoration, changed notes/scopes/counts and provider-state readback remain covered.
+Four complete 101-Todo source/wheel × File/SQLite CLI lifecycles preserve sum45,
+original completion time, four receipts, one debit, restart and refusal/replay;
+each owns and observes two normal native process exits. The isolated wheel's
+runtime source bytes match the checkout. Validation uses macOS arm64,
+CPython3.13.5 and Node22.22.3. Earlier toolchain/setup failures and a service-env
+skip remain preparation evidence, distinct from the qualified runs.
+
+This removes redundant scalar digest work; it is not a matched-cost or full
+marginal-cost/adoption result. Frozen cost, attribution and normal-bytecode
+campaigns remain unchanged. Preserve the original complete transaction and all
+I3/minor-release, M1/#8011, full R0/V10/R1, D2/D5/D6/D3,
+context/model/split-install, PostgreSQL host/wheel and historical failure gaps.

+separate gates; no installed-host upgrade or Goal completion is claimed.

 separate gates.
+
+### 2026-11-09 — Combined report and canonical-source caller qualification
+
+The original #8360 proposal now combines report construction isolation with
+the scalar comparison from #8372 and complete validated source-basis reuse from
+#8374 over target main `aee777008`. Runtime qualification uses
+`8b4df2fac966933e200ba15bb36b2f7afb9a194a` and preserves the original proposal's
+ancestry. The same existing report and typed Todo owners retain configuration
+validation, complete canonical reads, source/revision/lease protection and
+receipt/refusal/replay semantics; no decoder, authority cache or provider is added.
+
+Four fresh 101-Todo source/wheel × File/SQLite complete CLI lifecycles retain
+the original fixture/artifact fingerprints, scopes and completion time, four
+receipts, one debit and two observed normal native exits each. All 1,921 present
+tracked wheel entries match source bytes; seventeen existing source-only,
+documentation and media omissions remain. On Node 22.22.3 and CPython 3.13.5,
+the control-plane typecheck and 105 adjacent TypeScript cases pass. Real isolated
+PostgreSQL 16.15 store/service checks pass (391/11, zero skips), and the owned
+server is stopped afterward.
+
+The isolated wheel's packaged browser passes `typed-actions`,
+`conversation-activity` and `conversation-history-recovery` with synthetic
+upstream data. The original exact interruption assertion and completion/Turn
+isolation remain. Extended report caller checks return 70 passes and one failure:
+the calendar capability-action test expects a missing `turn_envelope`. The same
+test fails identically on immutable target main `aee777008`; this is retained
+as an unresolved validation gap, not relabeled as passing. Initial relative
+interpreter, installed-package provenance and missing-browser preparation
+failures are retained separately from the qualified runs.
+
+This combined boundary qualifies integration correctness, not whole-path or
+full marginal-cost/adoption benefit. Frozen cost, attribution, normal-bytecode
+campaigns, every original acceptance gap and historical failure remain intact.
+#8372/#8374 remain separate open proposals pending reconciliation; combination
+is not merge. Exact-head review, CI/readiness and explicit maintainer merge
+authority remain required. The original task stays open.
+
+### 2026-11-09 — Reconcile merged loading and the remaining source proposal
+
+Before publication, #8360 was observed merged as `e37a1d691`; #8011 is also in
+target main `520a1ab47`. The remaining source refinements now continue through
+the original #8372 proposal, preserving its `cbda59c6e` ancestry and incorporating
+#8374's complete-basis change. The merged report proposal is not recreated.
+
+Fresh runtime qualification at `4e72980bee91c7bbfcedb2eb481b8573113340b3` over
+that main passes 82 focused Python cases, 105 TypeScript cases, typecheck,
+real isolated PostgreSQL store/service (391/11), four complete 101-Todo
+source/wheel × File/SQLite lifecycles and the three packaged browser scenarios.
+Wheel ownership remains 1,921 matching entries and seventeen existing omissions.
+The standard premerge at that runtime revision passes six direct and nineteen
+selected checks. The expanded report family remains 70 passed/one failed;
+immutable `520a1ab47` reproduces the same `turn_envelope` assertion failure.
+That unresolved packet-contract qualification remains a hold alongside exact-head
+review, required CI/readiness and maintainer merge authority. Initial collection,
+environment and interrupted interim runs retain their original limits.
+
+This reconciles shipped loading with the remaining reviewed source boundary;
+it does not close the original task, installed-host, PostgreSQL host/wheel,
+full-cost/adoption or any other retained acceptance. No frozen campaign is rerun
+or relabeled, and this lane performs no main merge.
+
+### 2026-11-09 — Reconcile the M0 ratchet after the merged status move
+
+The exact #8372 qualification head's CI fails its kernel-static prerequisite:
+merged #8011 moved `chat_status_api.py` into `chat/status_api.py`, reducing the
+root from 128 modules to 127, while the fixture still pins 128. The downstream
+Stage 2C, checks and aggregate pytest jobs reject their skipped/failed inputs;
+those results do not establish new runtime failures or passes.
+
+The existing M0 fixture now records measured main `520a1ab47` and lowers its pin
+to 127. Its schema, entrypoint allowlist, exact-count rule and over-budget
+rejection remain intact. The same seven kernel-static checks pass on CPython
+3.13 and 3.11. In the same isolated source tree, an added unapproved 128th root
+module still fails; removing only that synthetic module restores the pass.
+The original CI and local 127-versus-128 failures remain retained evidence.
+
+This repairs the validation handoff for an already merged module relocation;
+it neither moves another runtime owner nor changes a production limit. Pages,
+the separate report packet-contract gap, full CI/review/readiness and every
+original installed-host, PostgreSQL host/wheel, full-cost/adoption and frozen
+qualification remain separate. The complete original task stays open.
+
+
+### 2026-11-09 — Complete-source report caller qualification
+
+The M0 pin repair passes CI, together with the real PostgreSQL, typed kernel,
+TypeScript, browser and Stage 2C checks at the recorded proposal head. Integration
+now includes target main `1cba745f5` while retaining the original proposal ancestry.
+The report calendar CLI smoke still fails on that integrated source because it
+reads the retired `turn_envelope` carrier. Its `None` replan assertion also
+belongs to the old projected adapter: the complete source retains competing
+advice while the typed controller owns final capability precedence.
+
+The smoke now gives the single `work_contract` directly to the existing controller.
+Across plan, dry-run and executing generic/Codex CLI calls, it checks the same
+owned next command, idle host, absent premature report artifacts and unchanged
+effect flags. A changed command with the original source binding is rejected.
+Dropping the next command from the real CLI result makes the independent smoke
+assertion fail. No runtime decoder, compatibility adapter or authority owner is added.
+
+The source and isolated-wheel report families each pass all 71 cases; 101
+adjacent Python cases and the control-plane typecheck pass. All inventoried
+present tracked wheel entries match the source bytes.
+This closes the stale caller-test gap without claiming new execution semantics,
+full-cost/adoption benefit or installed-host qualification. Initial reader-choice
+and missing-bundle preparation failures remain separate evidence. Pages retains
+its known out-of-scope broken link; exact-head CI, review/readiness, maintainer
+merge authority and every original acceptance/frozen campaign remain open.
+
+
+### 2026-11-09 — Complete CLI qualification across native context integration
+
+The retained follow-through plan now runs through complete 101-Todo CLI
+lifecycles, rather than stopping at report cases. Source and isolated wheel ×
+File/default-SQLite pass at proposal `bb65769cc`. The next target-main snapshot
+`3b16b8491` adds native preparation/navigation changes; the combined runtime
+`9baeafd8a` passes the same four complete lifecycles with a newly rebuilt wheel.
+
+Every case retains the original immutable synthetic fixture and independently
+verified sum-45 artifact, complete source/lease/refusal/replay/recovery checks,
+four committed receipt kinds, one debit, unchanged completion time and two
+observed normal native exits. The existing scalar/source-basis owner bytes
+remain unchanged. All inventoried present tracked wheel entries match this
+runtime source. Seven progressive-context contract cases and its typecheck pass.
+The stale frontend bundle's initial wheel-build refusal remains separate from
+the rebuilt package's qualification.
+
+This is integration correctness for the recorded source/package snapshots.
+It does not rerun or relabel the frozen cost, attribution or normal-bytecode
+campaigns, qualify current browser/installed-host or PostgreSQL host/wheel
+behavior, or establish full marginal-cost/adoption benefit. Current exact-head
+CI, review/readiness, maintainer merge authority and the existing out-of-scope
+Pages hold remain separate. The original task and all original acceptance stay open.
+
+### 2026-11-09 — Minimum supported Python CLI qualification
+
+CPython 3.11.15 now qualifies the complete 101-Todo source/isolated-wheel ×
+File/default-SQLite lifecycle at `15c937821`, extending the earlier 3.13
+qualification. Target main `a3b589610` subsequently changes context reading and
+settlement guidance; integration `220275f6a` repeats the four complete paths
+against that new input and a newly built wheel. Both groups preserve the same
+immutable fixture and independently verified sum45 artifact, original completion
+time, full source/lease/refusal/replay/recovery behavior, four committed receipts,
+one debit and two observed normal native exits per case.
+
+The earlier source and wheel each pass nine canonical-source cases; the current
+integration separately checks the merged report CLI caller in both distributions.
+Loaded wheel modules retain package provenance. Inventoried tracked entries
+present directly in the new wheel match source bytes; inventory counts are not
+used as a benefit comparison. Merge reconciliation retains the upstream module
+baseline and unchanged 127-module limit, explicit transaction-detail delivery,
+capability precedence and the original source-binding negative assertion.
+
+The private verifier's initial Python syntax failure and stale-bundle build
+refusal remain preparation failures, distinct from runtime qualification. The
+previous-head synthetic 200-item lens-switch CI budget failure remains a hold;
+these CLI checks do not qualify browser performance. No frozen cost, attribution
+or normal-bytecode campaign is rerun or relabeled. I3/minor-release, M1/#8011,
+full R0/V10/R1, D2/D5/D6/D3, context/model/split-install, PostgreSQL host/wheel,
+installed-host, full-cost/adoption and all historical gaps remain open. Exact-head
+review, required CI/readiness and maintainer merge authority still apply.
+
+### 2026-11-09 — Current-main required-Vision refusal qualification
+
+The proposal incorporates `main@aa475b29f` and its merged #8388 qualification
+repair at integration `2dd6c3d97`. The existing qualification adapter preserves
+the native `refresh-state` refusal output for required Vision while retaining
+its nonzero status and existing feedback bound. A missing stride cannot append
+writeback or spend; the caller can inspect the structured refusal, correct the
+same draft and then settle once. The typed writer remains the decision owner.
+
+On macOS arm64 with CPython 3.11.15 and Node 22.22.3, the complete existing
+required-Vision family passes 35 cases from source and 35 from an isolated wheel.
+The source-pinned `a3b589610` adapter fails the new missing-stride correction
+case. An initial comparison accidentally loaded the candidate through pytest's
+checkout insertion; that pass is invalid as a baseline result. The corrected
+comparison and wheel run verify every loaded LoopX module's package origin.
+These are scripted synthetic native-CLI qualification cases, not model results.
+
+The wheel matches 1,921 directly corresponding tracked ZIP entries, including
+the qualification adapter. This count is not compared with historical inventory
+methods. `read_transaction.ts` and `summary_item.py` retain the bytes qualified
+at `86d08a01c`; the earlier complete 101-Todo File/SQLite source/wheel lifecycle
+and PostgreSQL API/store evidence are retained, not rerun or relabeled. Standard
+premerge at the integration head passes six direct and nineteen selected checks.
+The bounded refactoring pass needs no additional production abstraction here;
+the existing writer and feedback boundary already own this behavior.
+
+The review published for `86d08a01c` remains historical evidence for that head.
+The updated proposal still needs current-head CI, review and merge readiness;
+this qualification grants no merge authority. Preserve the original transaction,
+I3/minor-release, M1/#8011, full R0/V10/R1, D2/D5/D6/D3,
+context/model/split-install, PostgreSQL host/wheel, installed-host, complete-cost
+and adoption gaps, and all frozen negative results. No kernel completion or
+whole-path benefit is claimed.
+
+### 2026-11-09 — Reuse fresh canonical field digests in quota reconstruction
+
+The proposal incorporates `main@c44eb156d`. A complete canonical read already
+returns a digest for each projected Todo field. Quota reconstruction now uses
+that digest from the same fresh in-process read rather than hashing the entire
+field again. The existing selector path retains its direct hash comparison.
+Complete cloning, immutable provider facts, source revisions, role checks and
+caller-change rejection remain in the existing TypeScript owner. The digest is
+neither caller-provided authority nor retained across requests; supplied-source
+fallback is unchanged. No protocol, configuration or provider is added.
+
+The current source and isolated wheel each pass 24 complete-source cases; 76
+adjacent planning cases, 23 native read cases and control-plane typing pass.
+A swapped user/agent digest is rejected, followed by a successful valid pair.
+The same negative case passes on the current-main baseline; removing digest
+rejection in an isolated source copy makes both File and SQLite cases fail.
+Every loaded LoopX module is checked against its selected source or wheel.
+Current-main and candidate source File/SQLite CLI lifecycles, plus candidate
+wheel File/SQLite lifecycles, preserve the same 101-Todo fixture and sum45
+artifact, original completion time, refusals/replay/restart, four committed
+receipts, one debit and two normal native exits per case. The initially stale
+frontend bundle refused packaging; rebuilding through its existing owner makes
+the new wheel build pass. These are correctness checks, with no cost comparison
+or rerun of frozen campaigns. All earlier acceptance gaps and negative evidence
+remain open; the changed head needs fresh review, CI and merge readiness.
+
+
+### 2026-11-09 — Kernel integration with the prospective M2 qualification
+
+The original #8372 branch integrates target main `6787fc8d5`, including the
+prospective Dashboard qualification in #8433. Kernel runtime `17d85c971` passes
+53 source and 53 isolated-wheel Python cases, twelve focused TypeScript cases
+and typing. All 1,921 directly corresponding tracked wheel entries match. The
+same six complete 101-Todo base/candidate source and candidate-wheel File/SQLite
+CLI lifecycles retain the fixture, sum45, original completion time, complete
+scopes, four receipts, one debit, restart/refusal/replay and two normal native
+exits per case. Real isolated PostgreSQL16.15 store391/service11 pass without
+skips. The same current PostgreSQL source-protection harness passes base/head;
+a primitive-protection mutation fails its expected-rejection oracle. Standard
+premerge passes six direct and nineteen selected checks. Local runtime checks
+use CPython3.13.5; CLI and mutation qualification use Node22.22.3, while the
+focused source and full PostgreSQL suites use Node26.0.0. Initial packaging,
+fixture-import and mutation-snapshot preparation failures remain distinct.
+
+This qualifies kernel integration correctness. It neither repeats frozen cost,
+attribution or normal-bytecode campaigns nor qualifies Linux browser recovery,
+installed-host, PostgreSQL host/wheel, full marginal-cost or model/team adoption.
+Keep every historical failure and original acceptance open. The prospective M2
+rule does not turn a historical frozen failure into a pass; unchanged-head
+review, required validation and fresh merge readiness still govern delivery.

+本次是记录中源码/包快照的组合正确性。不重跑或重标签冻结成本、attribution 和
+normal-bytecode campaign，不证明当前 browser/installed-host、PostgreSQL
+host/wheel 或完整边际成本/adoption 收益。新 exact-head CI、review/readiness、
+maintainer 合入权限和既有域外 Pages hold 分别保留。原任务及全部原验收保持开放。
+
+### 2026-11-09 — 最低支持 Python 版本的完整 CLI 验证
+
+CPython 3.11.15 在 `15c937821` 上完成 101-Todo 源码/隔离 wheel ×
+File/default-SQLite 四条完整 lifecycle，补充此前的 3.13 资格。目标 main
+`a3b589610` 随后更新 context reader 与结算指引；组合 `220275f6a` 对这份新输入
+及重新构建的 wheel 再验证相同四条路径。两组均保留相同 immutable fixture、
+独立校验的 sum45 artifact、原完成时间、完整 source/lease 拒绝及重放/恢复行为，
+每个 case 四种 committed receipt、一次 debit 和两个已观察到的正常 native exit。
+
+前一组合的源码与 wheel 分别通过九项 canonical-source 用例；当前组合另在两个
+distribution 验证合并后的报告 CLI caller。已加载的 wheel 模块保持包来源；新 wheel
+中直接存在的已盘点 tracked 条目与源码字节一致，不以盘点数量作收益比较。冲突协调
+保留上游 module baseline、不变的 127 上限、显式 transaction detail、capability
+优先级及原 source-binding 篡改负例。
+
+私有 verifier 初次 Python 语法失败和旧 bundle 构建拒绝仍属于准备失败，与 runtime
+资格分别保留。前一 head 的合成 200 项 lens-switch CI 预算失败仍为 hold；本次 CLI
+检查不证明 browser 性能。不重跑或重标签冻结成本、attribution、normal-bytecode
+campaign。I3/minor-release、M1/#8011、完整 R0/V10/R1、D2/D5/D6/D3、
+context/model/split-install、PostgreSQL host/wheel、installed-host、完整成本/adoption
+及全部历史缺口保持开放。exact-head review、必需 CI/readiness 和 maintainer 合入
+权限仍分别适用。
+
+### 2026-11-09 — 最新 main 的必需 Vision 拒绝资格
+
+提案接入 `main@aa475b29f` 及其已合入的 #8388 资格修正，集成 head 为
+`2dd6c3d97`。现有资格适配器为必需 Vision 保留原生 `refresh-state` 的拒绝输出，
+同时保留非零退出状态和原有反馈大小边界。缺少 stride 时不能追加写回或扣额；
+调用方可以读取结构化拒绝、纠正同一份草稿，再结算一次。typed writer 继续拥有决策。
+
+在 macOS arm64、CPython 3.11.15 和 Node 22.22.3 上，现有完整必需 Vision 家族
+在源码和隔离 wheel 中各通过 35 项。固定到 `a3b589610` 源码的旧适配器在新增的
+缺 stride 纠正用例中失败。初次对照因 pytest 插入 checkout 路径而意外加载候选，
+该通过不能作为基线结果；纠正后的对照及 wheel 运行核验了全部已加载 LoopX 模块的
+包来源。这些是脚本控制的合成原生 CLI 资格用例，不是真实模型结果。
+
+wheel 的 1,921 个直接对应已跟踪 ZIP 条目字节匹配，包含资格适配器；不与历史盘点
+方法比较数量。`read_transaction.ts` 和 `summary_item.py` 保留 `86d08a01c`
+已验证的字节，先前完整 101-Todo File/SQLite 源码与 wheel 生命周期及 PostgreSQL
+API/store 证据继续保留，不重跑或重标签。集成 head 的标准 premerge 通过六项直接
+检查及十九项选中检查。此次有界重构审视无需再添加生产抽象，现有 writer 和反馈
+边界已拥有该行为。
+
+针对 `86d08a01c` 发布的 review 仍是该 head 的历史证据；更新后的提案仍需当前
+head 的 CI、review 和 merge readiness，本次资格不授予合入权。原事务、I3/minor-release、
+M1/#8011、完整 R0/V10/R1、D2/D5/D6/D3、context/model/split-install、
+PostgreSQL host/wheel、installed-host、完整成本和 adoption 缺口及全部冻结负面结果
+均保留。不宣称最小内核完成或完整路径收益。
+
+### 2026-11-09 — 在 quota 重建中复用新鲜 canonical 字段摘要
+
+提案接入 `main@c44eb156d`。完整 canonical 读取已为每个投影后的 Todo 字段
+返回摘要；quota 重建现在复用同一次新鲜进程内读取生成的摘要，避免再次对整个
+字段计算摘要。现有 selector 路径保留直接摘要比较。完整克隆、不可替换的 provider
+事实、来源修订、角色检查及调用方改动拒绝仍由原 TypeScript owner 负责。该摘要
+不来自调用方授权，也不跨请求保留；完整 supplied-source fallback 不变。没有新增
+协议、配置或 provider。
+
+当前源码与隔离 wheel 各通过 24 项完整来源用例；76 项相邻规划用例、23 项原生
+读取用例及 control-plane 类型检查通过。交换 user/agent 摘要会被拒绝，后续合法
+配对仍成功。同一反例在当前 main 基线上通过；隔离源码副本移除摘要拒绝后，File
+和 SQLite 两项均失败。所有已加载 LoopX 模块均核验所选源码或 wheel 来源。
+当前 main 与候选源码的 File/SQLite CLI 生命周期，以及候选 wheel 的 File/SQLite
+生命周期，均保留同一 101-Todo 夹具与 sum45 产物、原完成时间、拒绝／重放／重启、
+四类 committed 收据、一次扣额及每项两次正常原生退出。首次打包因 frontend bundle
+过期而拒绝；由现有 owner 重建后，新 wheel 构建通过。这些是正确性检查，不进行
+成本对照或重跑冻结实验。全部既有验收缺口与负向证据继续开放；新 head 仍需新鲜
+review、CI 与 merge readiness。
+
+
+### 2026-11-09 — 接入前瞻 M2 资格的内核集成
+
+原 #8372 分支接入目标 main `6787fc8d5`，包含 #8433 的前瞻 Dashboard 资格规则。
+内核 runtime `17d85c971` 通过源码和隔离 wheel 各 53 项 Python、十二项 focused
+TypeScript 与类型检查；1,921 个直接对应已跟踪 wheel 条目字节一致。相同六条
+101-Todo 基线／候选源码和候选 wheel × File/SQLite 完整 CLI lifecycle 保留原
+夹具、sum45、原完成时间、完整 scopes、四类收据、一次扣额、重启／拒绝／重放
+及每项两次正常 native exit。真实隔离 PostgreSQL16.15 store391/service11
+零跳过通过；相同的当前 PostgreSQL 来源保护 harness 在 base/head 通过，移除
+primitive 保护的 mutation 则在预期拒绝 oracle 失败。标准 premerge 通过六项
+直接检查和十九项选中检查。本地 runtime 使用 CPython3.13.5；CLI 和 mutation
+资格使用 Node22.22.3，focused 源码及完整 PostgreSQL 套件使用 Node26.0.0。
+初次打包、fixture import 和 mutation snapshot 的准备失败分别保留。
+
+本次验证内核集成正确性，不重跑冻结成本、attribution 或 normal-bytecode
+campaign，不证明 Linux browser 恢复、installed-host、PostgreSQL host/wheel、
+完整边际成本或 model/team adoption。全部历史失败与原验收继续开放；前瞻 M2
+规则不会把历史冻结失败改记为通过。未变 head 的 review、必需验证与新鲜 merge
+readiness 继续分别约束交付。

+### Inspect cached images by case

+The worker's existing Docker preflight records the local image ID and logical
+size for the work and judge images in `runtime-receipt.json`. Review observations
+across selected run directories without reading trajectories or contacting Docker:

+observations by task specification digest, image role and image ID. It counts
+older receipts without observations and keeps distinct image revisions separate.
+Docker's logical image sizes include shared layers. Use them for cache inventory,
+and measure incremental disk use and runtime memory separately. Observations
+describe the worker's local Docker daemon at preflight. A remote judge requires
+its own image provenance, and a later retag can change what gets launched.

 An absent attachment preserves the current decision; an explicit `proxy: null`
 chooses direct evaluation while historical profiles remain readable.
 
+A current decision can reuse explicitly cited measurements from earlier
+findings by the same agent on the linked question. Each profile keeps its own
+input and evaluator revisions, and cross-profile comparison still requires the
+same candidate pair. Findings with their own Yardstick decision retain their
+original work and target scope.
+The primary settlement records a server-owned canonical event-prefix count and
+content-bound event-id digest for these citations. Attachment recovery verifies
+that original prefix; later ingestion order cannot expand its evidence. Old
+captures without this source snapshot remain readable, but plain cited
+measurements stay unknown rather than acquiring the recovery-time graph.
+Readback replays that prefix through the existing Explore projection, so a later
+update to the same finding cannot rewrite its cited measurement.
+The server-only source snapshot stays out of presentation capture payloads;
+independently installed readers retain the existing decision/binding wire shape.

+使用 `loopx upgrade` 或 snapshot 安装器时，会在启用候选运行时前，通过已有的
+`authority-archive upgrade --all-known --execute` 流程备份并迁移这些旧元数据。
+直接通过 pip 安装、源码运行或恢复旧备份时，可先只读检查：
+
+```bash
+loopx authority-archive upgrade --all-known --require-current
+# 需要迁移时，先备份原字节，再执行迁移
+loopx authority-archive upgrade --all-known --execute
+```
+
+原 registry 保存在相邻 `backups/registry-preimages/` 下，迁移结果返回具体备份路径。
+迁移保留暂停意图；字段冲突时保持停止，不会自动 Resume，也不改 Todo、执行回执或额度。
+之后仍可从「已停止」区或上面的同一 CLI 恢复。迁移失败时升级不会宣称完成，备份保留，
+原命令可重试；不要用备份覆盖迁移之后产生的新工作。
