 and synthetic grading. It does **not** qualify scientific research utility,
 matched strategy results, or the frontend restore journey. Actual task/profile
 admission and measured continuation outcomes remain required.
+
+### Continue an interrupted Host in its retained filesystem
+
+The explicit `benchmark.runtime.scheduler` budget-continuation entrypoint can
+settle a returned, budget-interrupted native Host before the next normal wake.
+It retains the original scheduler attempt, wake receipt, Goal, Todos and native
+conversation. A new append-only phase records the exact source and one finite
+deadline; retrying that phase cannot refill time. The next wake still performs
+ordinary quota, Stop, current-profile and session checks. No tool is replayed,
+work marked complete, or replan obligation discarded by this settlement.
+
+New scheduler-owned attempts carry an attempt identity and passive process
+cleanup observations. Recovery requires one matching returned budget receipt,
+a terminated original process group, the unchanged session binding, and stable
+native history ending in an interrupted Turn within that process window.
+Unknown failures, live processes, pending native effects, ambiguous receipts,
+changed profiles and stopped Goals remain held. Ordinary scheduler invocation
+does not opt into continuation. Completed-checkpoint admission stays unchanged.
+
+An older worker without the process observation can instead retain its exact
+stopped Docker filesystem. Prepare evidence through the existing Docker archive
+provider; do not substitute an older sealed checkpoint or copy files over the
+current workspace. The declaration names the original `goal_id`, `agent_id`,
+`workspace`, `runtime_root`, `native_home`, `registry`, `scheduler_state`,
+`wake_log_dir`, `phase_clock` and `wake_turn_id` (absolute guest paths for paths).
+For example:
+
+```sh
+python -m benchmark.edgebench.stopped_recovery \
+  --source-container FULL_CONTAINER_ID \
+  --declaration /private/recovery/source.json \
+  --output /private/recovery/source-proof.json --install
+```
+
+The command refuses a running container, non-inert restart command or external
+mounts. It inventories the current workspace, runtime, registry, original wake,
+native history and SQLite WAL/journal companions, then verifies the container
+remained stopped. `--install` places and reads back only a content-addressed
+inert proof in that same container's control directory; omitting it is read-only.
+Neither form starts the container, restores scoring authority or calls a model.
+Keep exclusive ownership of the source during preparation and continuation.
+
+The legacy source may still say `started`, or may already record a returned
+`stopped` attempt with exit code 75. The latter requires the unique latest wake
+receipt at or before that scheduler snapshot, with `host_invoked=true`,
+`budget_exhausted=true` and `timed_out=true`, no failure, and the original agent
+session. It is not the pre-dispatch budget shortcut. Preparation preserves the
+returned stop rather than changing it to `started` or inventing an attempt ID;
+the receiver must still verify the original native interrupted tail and current
+Goal/session admission. A later or ambiguous wake keeps the source held.
+For a returned stop, the native window ends at the receipt's recorded second,
+not a later maintenance stop of the container. The original hard deadline stays
+intact even when an older worker reserved cleanup time before it.
+
+After independently restoring the original native evaluator's history,
+opportunities and actual cooldown, restart only the same inert container and
+pass its returned `installed_proof_path` as `LOOPX_INTERRUPTED_SOURCE` to the
+explicit scheduler continuation. Preserve all original guest paths, native
+configuration and session. Hot-upgraded LoopX source belongs outside inventoried
+directories. Supply the separately admitted remaining allowance through the
+existing `LOOPX_PHASE_DEADLINE_EPOCH`; leave the original phase-clock file intact
+for source verification. Any changed participant, including a missing WAL,
+refuses settlement. A held reason is printed and the original phase remains
+selected; inspect the original evidence rather than delete it or select fresh.
+
+This provider path qualifies transport recovery, not a new sealed research point
+or cross-container restore. It never grants evaluator registration, budget,
+execution authorization or scientific comparability. Keep the prior failed
+segment and new segment separately attributable, and verify actual model activity
+and native feedback after dispatch. Disposable tests exercise real Docker archive
+and proof installation; SQLite/process tests exercise interrupted work followed
+by the same session's next Turn without paid model calls.
+
+The legacy stopped-source path accepts only Docker's default container-ID hostname.
+The receiver derives the current UTS hostname independently and refuses copied
+proofs in a different worker, including custom-hostname sources. This is an
+accidental-cross-worker boundary under the trusted Docker operator, not a
+cryptographic defense against that operator spoofing hostnames. The installed
+proof initially has root ownership and mode `0600`; a non-root worker's operator
+must assign that one inert file to the original execution user before consumption.
+Only verified SQLite `-shm` companions are omitted as rebuildable indexes; arbitrary
+workspace files with that suffix remain protected.
+
+An explicitly continued phase can carry a hash-bound content handoff through
+`LOOPX_RECOVERY_HANDOFF` and `LOOPX_RECOVERY_HANDOFF_SHA256`. Use the existing
+`handoff restore --input FILE --format json` content envelope (`ok: true` and
+`handoff_text`), without ownership arguments. The normal heartbeat presents it;
+a successful same-session Host receipt confirms its digest and stops repeated
+presentation. An uncertain attempt retains the same input, and missing or changed
+bytes fail closed. A legitimate later budget phase can bind its own new handoff;
+the earlier phase and digest remain immutable. Native submission-ID remapping
+belongs in this infrastructure handoff, never a replacement solution Todo.
+
+Recovery settles process transport only. Preserved pending semantic replan
+attempts still require their original settlement owner; an interrupted replan
+is not silently declared complete or cleared to force dispatch.
+
+### Explicitly continue after native account allowance is repaired
+
+A hard native quota failure is still held by default. Repair or replenish the
+authorized experiment account through its existing provider and verify its fresh
+allowance before requesting another phase. This does not change the desktop
+login, waive a Stop, refill evaluator opportunities, or turn hard quota failures
+into automatic timed retries.
+
+For a retained complete worker, the same scheduler entrypoint accepts
+`--retry-failed-state-sha256 SHA256` naming the exact original scheduler file.
+Supply the independently admitted finite remainder in
+`LOOPX_PHASE_DEADLINE_EPOCH`, preserving the original phase clock and failed
+receipt. The caller must retain the workspace, Goal/SQLite, session, evaluator
+history and cooldown; this entrypoint cannot reconstruct missing source data.
+For example, after these provider and source checks:
+
+```sh

+The recovery provider requires one returned `quota_exhausted` wake, its original
+session/profile binding, terminated native process group and a stable native
+`failed` tail with the corresponding structured quota error and no pending tool
+effects. Legacy workers can use the same stopped-container proof above, but only
+when the exact last returned failure, original session and complete unchanged
+filesystem are retained. Unknown errors, missing sessions and incomplete history
+remain held. The ordinary completed-checkpoint gate is unchanged; a failed native
+Turn is not rewritten or presented as completed.
+
+The shared Turn retry rule decides explicit-retry eligibility. A new append-only
+phase records the original failure, digest, native cursor and deadline, retains
+the Host attempt count and semantic replan records, and starts through normal
+Goal/Stop/session/work admission. Repeating the request selects that same phase,
+including any later failure; it cannot clear the failure or extend its deadline.
+A later explicit repair must bind that new failure separately. Existing operator
+and account authority remain required; a digest is provenance, not permission.
+
+The explicit failed-phase path additionally uses the installed optional native
+Codex provider's existing availability policy (`loopx-codex-provider-routing`).
+It reads `account/read(refreshToken=false)` and `account/rateLimits/read` in a
+fresh disposable inspection home before creating the phase. Missing provider
+support, unknown allowance, exhausted allowance or a changed Goal/session keep
+the original failure held. Only a bounded availability receipt is retained;
+no account response, login values or token is emitted. The ordinary startup
+probe and automatic retry path keep their previous behavior. This observation
+is not a reservation of future provider capacity; a later failure is retained
+and requires another explicit repair.

 ## Research checkpoint storage
 
+New native non-game runs give every worker profile the same research directory,
+`/tmp/loopx-benchmark-research`, outside the task workspace and submitted paths.
+Keep experiment notes, local probes and candidate history there; required build
+and runtime inputs still belong in the task's declared submission paths. The
+runner does not filter submissions, extend evaluator feedback or alter grading.
+Overlapping submission/capture roots and existing unrelated data at this reserved
+path reject setup before solver execution.
+
+Terminal collection retains this directory under `collected/research`. With an
+explicit checkpoint request, the runner adds a separate `benchmark_research`
+component to the staged declaration, without modifying the caller's file. Warm
+continuation restores that exact component at its original path through the
+ordinary verified research-file transport. Other external research components
+still require explicit selection. Old checkpoints remain valid and preserve
+their workspace files; they start with an empty external research directory,
+without automatic relocation or deletion of historical artifacts. A warm receiver
+appends a bounded storage-policy update to its existing `AGENTS.md`, preserving
+the original task text and prior feedback policy; it does not rewrite the sealed
+checkpoint or Goal state. Terminal
+collection alone does not make a run resumable. Game and restricted-feedback
+runs retain their existing storage behavior.

+## Preserve a failed worker before teardown
+
+For a new heartbeat run with full native controller capture, add
+`--preserve-failed-worker` to preserve the last source after a nonzero or uncertain
+solver exit. This is opt-in and requires agent-only submissions (`--eval-interval 0`);
+ordinary runs, successful exits and Native Goal completion keep their previous
+cleanup behavior. Removing the option disables the policy for later runs; it does
+not delete a previously retained worker.
+
+At the exact solver-return boundary, before the native provider stops its work
+container, the adapter closes the periodic observer and attempts one bounded joint
+capture through the existing Docker writer barrier and native checkpoint owner.
+It captures the complete task workspace, declared external research components,
+Goal state, scheduler/wake evidence, native session/configuration and native SQLite
+participants (including committed WAL data). It never exports the native credential
+home or `auth.json`. The native capsule retains its own submission history,
+incumbent, opportunity counter, cooldown and original phase. No new submission,
+model request, successful settlement or extended clock is created.
+
+The trial's private `terminal-preservation.json` records the original execution,
+export outcome/digest, preservation time and confirmed stopped-container state.
+The file export explicitly remains **unqualified for restoration**: a failed native
+Turn is not a completed conversation checkpoint. Both successful and failed exports
+retain the original stopped container until an operator separately qualifies a
+receiver or authorizes disposal. Compute is stopped before returning to provider final-archive extraction or
+grading drain, and cleanup verifies that stop again;
+a stop failure is reported without deleting the source. Missing participants, full
+storage or an uncertain writer barrier cannot fall through to force-removal.
+The provider still performs its ordinary network/proxy cleanup and grader drain.
+Its best-effort final submission archive may be absent because its extraction
+requires a running container; latest files remain in the stopped source and, on
+successful export, the terminal point. Native graded history/results remain
+independent and are not discarded with that optional archive.
+
+If the optional preservation receipt cannot be written, a redacted warning reports
+that gap; observer shutdown, one capture attempt and verified source stopping
+still proceed. The known solver exit and native grading remain authoritative.
+An unconfirmed stop still fails explicitly, even if receipt storage also fails.
+Missing receipt files never establish successful export or recovery eligibility.
+
+Inspect this receipt, the exported manifest and the exact retained container before
+planning recovery. Do not restart it, treat a file digest as receiver adoption, or
+roll back to an older point to fill a tail gap. Retained containers still occupy
+**disk** and may contain their original private credentials; reserve storage and
+explicitly dispose of the exact owned container after recovery/disposal approval.
+Terminal preservation does not rotate away the last qualified regular checkpoint,
+and it does not increase the daily/fresh-replan capture frequency.

+## Close a managed native attempt
+
+For a native-feedback run with an existing experiment-board row and a fresh
+concurrency admission, pass `--managed-run-json PRIVATE_BINDING.json` to the
+EdgeBench runner. Keep the binding owner-only and outside the solver workspace.
+It contains `goal_id`, the absolute controller `project` path, the original
+`admission_receipt` from `loopx benchmark concurrency-admit --execute --format json`,
+and the board `identity` (`benchmark_id`, `study_id`, `case_id`, `run_id`, `arm_id`,
+`arm_role`, `attempt`). Match `case_id` to `--task` and `run_id` to `--run-id`.
+Use the receipt that created the slot and a unique run ID across the Goal.
+
+The runner retains `managed-run.json` beside the runtime receipt. Before the
+solver starts, the receipt captures the binding and source pins. At return, it
+binds the original solver execution record when termination is confirmed. The
+runner publishes `managed-terminal.json` after validating those receipts and
+the native grading drain for the same run. The controller holds the registered
+Goal and project access.
+
+If grading drains later, the native grading owner must first retain its
+complete, drained `grading_status.json` and the matching history in the same
+attempt. To validate that evidence or retry a proof write, run the following
+once on the host that owns the attempt. Omit `--execute` to preview.
+
+```sh
+python -m benchmark.edgebench.managed_run --trial "$ATTEMPT_DIR" --execute
+```
+
+The replay reads retained evidence. Pending, unknown, or mismatched native
+evidence leaves the reservation active. After a terminal receipt write fails,
+replay can use the runner's completed result when it agrees with the original
+launch pins, the exact native solver record, and the drained grading history.
+Use the proof from the exact attempt on the controller and retain the command's
+JSON receipt with its binding.

+in the task input and workspace instructions. It neither requires delegation
+nor grants separate child evaluation opportunities, time, accounts or access.
+Only the parent submits candidates, and Stop still applies to the whole task.
+The option requires a non-game task with native feedback.

+or raise the native client's existing depth limit.
+
+LoopX arms additionally initialize their existing Goal spawn policy with the
+same limit. Host-native children are ephemeral host sessions, not registered
+LoopX Agents; this adds no peer scheduler, persistent Agent or delegation
+binding. The existing native-child receipt and context owners remain unchanged.
+The adapter reads back that Goal policy before later phases and restored work;
+it does not change an existing Goal to make a mismatch pass. Repeated same-session
+entry preserves the fixed configuration. Warm restore compares the requested
+limit, including omission, with the sealed native config before native activation.

+### 2026-11-07 — Caller process-transport loading proposal
+
+- **Baseline and boundary:** `7f521ff4505fa916a98a7401032922189eef414a`
+  loads `extensions.process_runtime` during the pure Turn-decision import.
+  Doctor Git, contract scanning, caller validation and Host bridge transport
+  now resolve their existing reexports on use. The original function objects,
+  signatures, direct/from/star imports, discovery, caller patch points,
+  preloaded-owner bindings and reload behavior remain available. This uses the
+  existing lazy-export pattern; the export-name set is local compatibility
+  metadata, not a shared state vocabulary. Python retains platform transport;
+  TypeScript retains decisions, deadlines, authority and receipts. No provider,
+  capability, default or process algorithm is added.
+- **Executable evidence:** the four cold-caller oracles fail on the immutable
+  baseline. Focused compatibility checks and the existing architecture oracle
+  pass on the proposal; the Turn-preview unselected-module guard is retained.
+  Real isolated Git, validation and bridge tests cover timeout, cancellation,
+  exited-leader descendants, stdin policy, framing and unconfirmed cleanup.
+  A newly built monolithic wheel repeats compatibility and real-process checks
+  outside the checkout. Complete public discovery/star name sets and transport
+  signatures match the baseline. This is source/wheel proposal evidence, not an
+  upgrade or adoption result.
+- **Measured scope:** pure Turn-decision import loads 337 LoopX modules instead
+  of 338. Pure import and help start no processes or connections; supported help
+  and unknown-command output/exit status remain identical. Shared synthetic
+  SQLite fixtures exercise accepted and rejected registered Turn plans: both
+  revisions start two Node processes and thirteen Git probes, with 62/61
+  connection observations respectively. Their complete returned envelopes match
+  except the source-decision digest from fresh observations. Registered plans
+  still select process transport; the entire preview dependency closure is not
+  qualified as cold. One removed import does not establish latency, RSS,
+  complete-cost, managed-Turn or long-horizon benefit.
+- **Remaining and rollback:** retain I3 for at least one minor release. D2, D5,
+  D6, I3, D3 and full R0/V10/M1/R1/context/model/install acceptance remain open.
+  Canary passes its six direct checks and 17 of 18 selected checks.
+  `first-connect-contract-smoke.py` fails with `KeyError: should_run` on both
+  baseline and proposal; its inline-field assumption needs separate repair.
+  This failure and existing broader lint/browser failures remain open.
+  The completed author proposal may enter normal review with disclosed
+  holds; protected runtime merge still requires maintainer authorization.
+  Revert this caller loading change to restore eager binding without state
+  migration; no unrelated language rewrite is required.
+
+### 2026-11-06 — History reader selected loading
+
+- **Baseline and boundary:** `22b0f6c25`. Ordinary `history` reads and help use
+  the existing registrar/handler through the shared CLI grammar and guard.
+  Maintenance actions, rejected parser requests and a preloaded full CLI retain
+  the original route, including handler/renderer patch points. History algorithms,
+  evidence windows, public imports and the TS owner remain unchanged. This is a
+  reversible R0 reader slice in the monolithic distribution; I3 still requires
+  at least one minor release for public moves.
+- **Real-path evidence:** 27 actual-console cases per baseline/candidate source
+  and installed-wheel environment preserve stdout/stderr/exit codes, UTC order,
+  Agent filtering, limits, empty/unknown inputs and current/stale evidence reads.
+  Four additional installed/source facade probes preserve patched handlers and
+  renderers. The preloaded-handler oracle failed before its correction; final
+  history/parser selection passes 26 tests. Existing durable history, artifact
+  and evidence oracles are retained. Required native services use disposable
+  process and data namespaces, with authenticated exit readback.
+- **Matched measurement:** Apple M4 Pro, 48 GiB, macOS 27 arm64, Python 3.13.5,
+  Node 26.0.0; matched Python dependencies and source-pair Node dependencies.
+  Each of four workloads has 30 interleaved baseline/candidate pairs, precompiled
+  bytecode and fresh Python processes with warm native-service reuse. The final
+  sampling takes 229 seconds; all three rounds total 698 seconds, below the
+  frozen 20-minute sampling bound. Setup, validation and tracing are separate.
+  Earlier environment/refinement observations retain their original scope.
+
+| Workload | Median / p95 elapsed ms, base → candidate | Median CPU ms | Median CLI peak RSS MiB |
+| --- | --- | --- | --- |
+| Source help | 1552 / 1862 → 204 / 349 | 670 → 100 | 91.4 → 31.3 |
+| Source Agent read | 1603 / 1833 → 417 / 482 | 665 → 150 | 91.9 → 34.4 |
+| Wheel help | 1621 / 2053 → 220 / 375 | 695 → 100 | 91.8 → 31.0 |
+| Wheel Agent read | 1648 / 1825 → 414 / 462 | 725 → 150 | 92.2 → 34.6 |
+
+- **Loading and effects:** source/wheel help loads 155 rather than 1157 LoopX
+  modules; registered reads load 208 rather than 1158, evidence reads 210 rather
+  than 1159. Python audit read-open observations decrease from 1290 to 246 for
+  source help and 1311 to 723 for its cold native read; wheel observations are
+  1291 → 247 and 1710 → 723. Help has zero observed writes/processes/connections.
+  Cold registered reads retain six write-opens, two process starts and one
+  connection, with 252/355 client IPC bytes sent/received. Evidence reads retain
+  one write-open, two connections and 1377/804 IPC bytes. These required effects
+  are not optional activation. A serving runtime can work without Node on PATH;
+  cold absence retains the existing failure. Output bytes match. Timing includes
+  interpreter and process invocation; descendant CPU/RSS/I/O, full model and
+  attention costs remain unknown.
+- **Holds and remaining work:** measured help p95 remains above the proposed
+  200 ms target; D6 is not adopted. Source-session loader inventory and Turn
+  preview import checks fail identically on the untouched baseline. Their failures
+  are retained as qualification holds. This does not close full R0/V10, M1,
+  split installation, R1/context/host qualification or open design decisions.
+  Revert the loader slice for rollback; no state migration is involved.
+
+### 2026-11-06 — Selected version loading and matched costs
+
+The independent proposal `8a79d8602e699e51452ca1f43dc9b9527c81aa1b` at baseline
+`5a58635028fbef1316dc66531daf5fdb655e9b13` selects the existing version registrar
+and handler through `cli_runtime`. It reuses the canonical global grammar,
+format precedence, usage hooks and controller guard. Rejected parsing retains
+full-CLI fallback and diagnostics; explicitly bound package or full-CLI exports
+retain their registrar/handler patch points without triggering lazy exports
+on ordinary queries. Public imports, identity and types remain
+unchanged. No capability, provider, package, permission, preset or TypeScript
+decision owner is added. The separate DSH/helper and negative cost proposal is
+[#8185](https://github.com/loopx-project/loopx/pull/8185); its E7/E8 observations
+are distinct from this version-path comparison and are not a dependency.
+
+The initial `55e3ef45a` comparison retains 120 ordinary-query observations
+(source median 1.546 → 0.059 seconds; wheel 1.554 → 0.072). A later independent
+case finds that it ignores a patched package-facade handler, returning 0 instead
+of 37. Its passing premerge did not cover that branch. The failure and original
+inputs/data remain retained; they do not qualify facade compatibility. The
+proposal repairs both package registrar and handler adoption, then freezes the
+new exact-head comparison below.
+
+- **Real caller:** source and freshly installed monolithic wheels at both
+  immutable revisions exercise the actual `loopx` console. All 27 cases per
+  distribution have identical stdout, stderr and exit status, including
+  global/local/repeated formats, explicit paths, help, unknown/abbreviated
+  options, missing/empty values and fallback. Independent unknown-command/
+  option cases reject with exit 2 and no result. Version works with Node absent
+  in all four variants; outer-controller read behavior and full-CLI patch points
+  remain compatible.
+- **Loading census:** separate parent instrumentation records 1,157 → 10
+  LoopX modules in both distributions, with the candidate contained in the
+  baseline set. Source read-opens are 1,286 → 28 and wheel 1,289 → 29.
+  Each version capture has zero write-opens, subprocesses, observed local IPC
+  connections and covered socket bytes. Stdout remains 81 bytes; stderr is empty.
+- **Frozen comparison:** all four environments have verified provenance,
+  CPython 3.13.5 and identical 57 dependency versions. Stdlib, dependencies and
+  all 1,421 LoopX sources have valid timestamp bytecode in owned cache prefixes;
+  post-measurement/profile source/header inventories have no missing/invalid
+  caches and match the preflight. Every sample has fresh Python and disables
+  bytecode writes; disk cache is uncontrolled. No broker/warm-broker comparison
+  is made. Order is source then wheel, AB on even pairs and BA on odd pairs.
+  Both corrected groups complete 30 pairs: 120 accepted observations in 62.246
+  seconds. Including the first study, aggregate sampling is 166.191 seconds,
+  below the unchanged 1,200-second cap. All observations are retained.
+
+| Distribution | Baseline seconds, median / p95 | Proposal seconds, median / p95 | CPU seconds, median (base → proposal) | RSS MiB, median (base → proposal) | Median paired proposal minus baseline, seconds |
+| --- | --- | --- | --- | --- | --- |
+| Source | 0.980 / 1.056 | 0.055 / 0.075 | 0.520 → 0.037 | 90.17 → 16.81 | -0.9242 |
+| Monolithic wheel | 0.948 / 1.147 | 0.056 / 0.077 | 0.511 → 0.038 | 89.89 → 16.60 | -0.8993 |
+
+p95 uses nearest rank; paired differences and differences of arm medians are
+distinct statistics. Median latency falls about 94% in both source and wheel
+on this macOS arm64 environment; CPU and target RSS also fall. One-minute host
+load ranges from 8.25 to 9.06. This qualifies a material version-query
+improvement under frozen conditions, without adopting portable D6 budgets or
+claiming real managed-Turn/long-horizon savings. Usage covers the target and
+waited descendants; no child is launched in the census. Native detail and
+complete authoring/model/maintenance costs remain unknown.
+
+The heartbeat-to-final-freeze interval is about 2,404 seconds, including
+overlapping recovery, initial study, correction, dependency/build/install,
+test, cache and parity work; overlapping phases cannot be summed. Cache
+preparation is recorded separately. Corrected console/facade parity takes
+82.759 seconds, instrumentation 2.539 and four parent profiles 4.155. Earlier
+parity/instrumentation/profile costs of 136.239 / 3.830 / 7.089 seconds remain
+retained. Cross-study timing levels are not treated as a code comparison.
+Existing `performance-diagnosis` recipes show export loading and full parser
+construction in baseline sampled stacks; weights remain separate from repeated
+latency. Monolithic packaging is verified, without split-install or installed
+host-upgrade qualification.
+
+Seven selected-loading cases fail on the baseline and pass on the proposal.
+The package registrar/handler case passes on the baseline, fails on the initial
+candidate and passes on the correction; canonical diagnostic and full-CLI
+patch-point cases pass in both baseline and proposal. All 161 entrypoint cases and
+focused lint pass. Owner-scoped mypy with `--follow-imports=skip` fails with
+33 identical diagnostics at base/proposal after line normalization; this is
+neither a pass nor the full configured type check. Adoption requires final-head
+validation, independent review and merge readiness. I3's minimum one minor
+release window remains in force; no D3/expiry decision is made. R0's wider census,
+R1/minimal, D2/D5/D6, hard-lease/context/model and split-install acceptance remain
+open. The bounded refactor reuses its existing parser/handler; larger runtime
+and package changes retain their accepted owners.
+
+### 2026-11-06 — Discovery integration and the next executable boundary
+
+- **Integrated:** [#8012](https://github.com/loopx-project/loopx/pull/8012)
+  merged the proposed head `58442be4d` as `83f569178` on November 4. On the
+  independently prepared `main` revision `62e234c93`, all 23 discovery and
+  protected-dispatch cases pass. Replay with
+  `uv run --extra test python -m pytest -q tests/test_cli_entrypoint.py -k 'capability_discovery or capability_non_discovery'`.
+  This verifies current source integration; the earlier installed-wheel and
+  paired performance evidence remains bound to its original revision and
+  environment. No installed host or new wheel is qualified by this replay.
+- **Resolved prerequisite:** [#8054](https://github.com/loopx-project/loopx/pull/8054)
+  (`886f2cdff`) removed capture I/O from the settlement plan's cold import.
+  `uv run --extra test python -m pytest -q tests/architecture/test_control_plane_import_boundaries.py::test_settlement_plan_import_does_not_load_native_capture_io`
+  passes on `62e234c93`. The November 4 failure remains historical evidence;
+  the later fix removes that specific import blocker. The broader suite and
+  configured mypy were not rerun on this revision, so their earlier results
+  do not become a current passing qualification.
+- **Next source slice:** characterize the existing `generic-cli` managed Turn
+  path with SQLite authority and optional task hooks disabled, as a candidate
+  for the selected D2/D5 composition. Reuse the Turn, host selector and typed
+  authority owners. Existing CLI interruption and successor-replay tests in
+  `tests/test_loopx_turn_driver.py` locate integration seams; they do not
+  establish a minimal preset. The next slice must name the actual dependency
+  closure and exercise an isolated task-producing host process, interruption,
+  restart and independently validated result readback with original identities
+  and no repeated confirmed effects. A deterministic local host can qualify
+  its synthetic transport boundary, not a model host or complete V4 journey.
+- **Remaining:** full R0/V10, M1/I3/D3, the separate status proposal #8011,
+  split installation and R1 remain open. D2/D5 are still owner decisions;
+  this candidate changes no preset, default, execution authority or release
+  commitment. Further directory moves are not the next execution evidence.
+
+### 2026-11-06 — Proposed generic-cli/SQLite composition and recovery evidence
+
+This is a D2/D5 candidate and source characterization, not an approved preset.
+It reuses the existing Turn, host selection, authority and settlement owners.
+
+| Dimension | Candidate / observed boundary |
+| --- | --- |
+| Installation | Current monolithic `loopx` source checkout; Python 3.13.5 and Node 26.0.0 on macOS arm64. Test extras prepare the experiment, not a minimal install. No split distribution or installed host is qualified |
+| Host | Existing `generic-cli`, `isolated-headless`, JSON stdio via `--host-adapter-command-json`; one local deterministic task-producing process and a separate trusted argv validator. No model session or workspace/IM service is needed by this fixture |
+| Authority | Canonical SQLite through the existing TypeScript effect runtime and its local RPC transport; existing Turn journal, validation and settlement. The test scaffold seeds a `soft_claim` shadow; this evidence cannot alone qualify normal hard-lease V2 parity |
+| Required logical core | Bootstrap/selected CLI, TurnEnvelope and host admission, current authority/stop/budget/claim rules, journal/recovery, process supervision, independent validation and result/settlement readback. Their owners remain shared with standard |
+| Optional activation | No task-memory or other optional hook is enabled in the fixture; no model jobs or external operations. Imported settings/policy helpers are not proof of activation or permission to remove them |
+| Identity and recovery | Resume the original journal with `--resume-turn-key`; a fresh `--turn-instance-id` is intentionally refused on that path. Cached confirmed host work is reused; unconfirmed work and other interruption points remain separately governed |
+
+- **Actual task and recovery:** a real host process writes the squared integers
+  zero through seven; an independent process checks the expected literal array.
+  Both the ordinary path and an OS `SIGKILL` of the owned CLI after its typed host
+  result was persisted end with one host invocation, one writeback and one debit
+  per isolated SQLite fixture. The interrupted path has no debit before restart;
+  restart validates the cached result without invoking the host again. A further
+  committed replay reports no repeated host/writeback/debit/scheduler effect.
+  The artifact bytes match across both paths. No active project state was faulted.
+- **Actual loading:** at product revision `62e234c93`, the ordinary Python path
+  loads 538 LoopX modules across 21 capability namespaces, without `loopx.cli`
+  or the `loopx.chat` tree. A second drill uses an isolated existing-runtime
+  broker and a transparent Node module-load observer: its bootstrap, execution
+  and recovery load 231 TypeScript files and eight JSON files under
+  `control_plane`. These are observed closures, not approved core membership.
+  The private broker's identity, shutdown acknowledgement and process exit were
+  verified; shared services were not stopped.
+- **Costs and limits:** parent-side tracing distinguishes required local RPC
+  from external network connections; none of the latter is observed. The
+  ordinary invocation observes 34 Git subprocesses, one Node version probe, one
+  Node host supervisor and one Python validator; the supervisor launches the
+  task host. Child/broker CPU and RSS, full wire/context bytes and model-host
+  costs remain unmeasured. These small instrumented drills are not repeated
+  matched performance samples, a D6 budget or long-horizon benefit evidence.
+- **Independent regression evidence:** the six SQLite cases of
+  `test_managed_start_interruption_preserves_reservation_and_attempt`, plus
+  `test_turn_run_once_cli_rejects_unproven_host_claim_before_writeback` and
+  `test_turn_run_once_cli_replays_declared_successor_after_interruption` pass in
+  `tests/test_loopx_turn_driver.py`. Probe setup refusals remain separate from
+  product failures: an overbroad network observer, an incorrect host-request
+  schema and conflicting resume flags were corrected without changing production
+  code or relaxing authority; failed observations were retained.
+- **Next owner change:** `loopx/cli_commands/turn_run_once.py` imports DSH host
+  builders before selecting the host, although their call sites are under
+  `args.host == "dsh"`. The generic path therefore loads
+  `turn_dsh_host` and `dsh_goal_mode.turn_host_adapter` despite selecting neither.
+  Characterize the existing exports/patch points, then defer those builders at
+  their owning seam and recheck generic/DSH/Codex behavior and default-off parity.
+  Namespace counts alone do not justify deleting shared policy helpers.
+- **Remaining:** opt-in minimal selection, complete D2/D5 adoption, hard-lease
+  and context V2/V5 parity, interruption during unconfirmed host work, model-host
+  V4, full V10 and split-install qualification remain open. No new engine,
+  provider, default, authority field or runtime self-merge is introduced.
+
+### 2026-11-07 — Heartbeat pre-quota selected loading
+
+- **Baseline and owner:** `79665b97a`. The heartbeat builder already emits
+  `heartbeat-prequota` when external evidence polling is available. Its selected
+  parser reuses the existing heartbeat registrar; dispatch uses the existing
+  heartbeat transport module. The complete facade passes its original runner,
+  renderer and global-registry resolver patch points. Explicit/implicit routing,
+  aliases, format, timeout, exception, degraded-return and controller semantics
+  remain characterized; reconciliation/hook ordering and typed owners are unchanged.
+- **Source and package evidence:** 50 new transport/loading/real-backend cases;
+  22 cases on each of four independently verified source/wheel consoles; 16
+  configured/degraded File/SQLite console scenarios with replay, retained opaque
+  work and zero quota debit. Dropping `continue_to_quota` is rejected by the same
+  public-console oracle on both real stores. The existing acknowledgement smoke
+  now exercises both CLI facades. The full source selection initially has 378
+  passes and two route-test failures reproduced on the immutable baseline. The
+  fixture now reads the original digest-bound progressive capture without
+  re-admission; its complete affected file then passes all 17 cases. No failure
+  was waived. Focused lint, configured mypy and the code canary pass.
+- **Matched local cost:** macOS 27.0 arm64, Python 3.13.5, Node 26.0.0; identical
+  dependencies and synthetic stores, precompiled bytecode, fresh Python processes,
+  warm filesystem caches and reused isolated Node services. Thirty alternating
+  base/head pairs for each workload/distribution yield 360 samples in 339 seconds;
+  study setup/validation takes 260 seconds separately. This shared development
+  host was not an idle-machine experiment. Values below are wall median/p95 in
+  seconds and median process RSS in MiB, including interpreter startup.
+
+| Workload / distribution | Base median / p95 | Candidate median / p95 | Base → candidate RSS |
+| --- | --- | --- | --- |
+| `source/prequota-help` | 1.433 / 1.889 | 0.172 / 0.226 | 91.5 → 24.7 |
+| `source/prequota-file-off` | 1.494 / 1.927 | 0.545 / 0.667 | 92.0 → 47.0 |
+| `source/prequota-sqlite-off` | 1.547 / 1.977 | 0.507 / 0.640 | 91.9 → 46.3 |
+| `wheel/prequota-help` | 1.555 / 1.967 | 0.170 / 0.210 | 91.7 → 24.5 |
+| `wheel/prequota-file-off` | 1.545 / 2.155 | 0.536 / 0.650 | 91.7 → 46.7 |
+| `wheel/prequota-sqlite-off` | 1.397 / 1.866 | 0.531 / 0.667 | 92.0 → 46.9 |
+
+- **Closure and complete-cost limits:** help loads 29 LoopX modules instead of
+  1,158; default-off execution loads 277 instead of 1,160. Python open observations
+  fall from 1,292–1,312 to 81–395. Opened-file size sums are footprints, not actual
+  read bytes. Median user/system process CPU is 0.04/0.02 seconds for candidate
+  help and 0.13–0.14/0.065–0.08 for execution, versus 0.40–0.42/0.16–0.185 at base.
+  Output remains 737 bytes for help and 827 for JSON execution. A separate SQLite
+  loopback profile observes 1,362 sent and 668 received bytes on each revision,
+  two Node starts for version/server discovery with a cold service and none with
+  a reused service. Its single instrumented cold/warm observations do not isolate
+  Node readiness or service CPU; those costs remain unqualified. The initial IPC
+  probe assumed Unix sockets and failed; loopback instrumentation corrected the
+  probe without changing product behavior. Help p95 of 0.226/0.210 seconds exceeds
+  the proposed 0.200-second target; that D6 proposal is not promoted or relabeled.
+- **Remaining:** this is one R0/V1/V3/V10 caller proposal, preserving I3 for at
+  least one minor release. Full R0/V10, M1/#8011, R1, context/model and split-install
+  qualification, installed-host recovery, adoption and complete task costs remain
+  open. The bounded Python change adapts transport; it adds no decision owner,
+  preset, provider or authority rule. Required final-head review/CI remains a
+  delivery gate distinct from these local observations.
+### 2026-11-07 — Registry inspection selected loading
+
+- **Baseline and boundary:** `ac6296225`. `registry` and `registry-boundary`
+  use the existing selected CLI route. Their shared registrar and transport
+  adapter stay in `cli_runtime`; the explicit full CLI reuses them through
+  `support_control`, retaining its inspection and renderer patch points.
+  Registry parsing, classification and Git decisions keep their existing owner.
+  Python adapts the CLI here; no new decision owner, provider or dispatcher
+  framework is introduced. Existing imports and I3's minimum one-minor-release
+  compatibility window remain intact.
+- **Compatibility evidence:** 197 source CLI and support-ownership cases pass,
+  including 26 new inspection/result/rejection/patch-point cases and two help
+  cases. An independent full-CLI loading exclusion fails on the immutable base
+  and passes on the candidate through the same public entrypoint. Twenty
+  successful and rejected requests preserve output, status and exception
+  semantics across source and independently installed monolithic-wheel consoles.
+  Help and read paths also work with Node absent and exclude the unselected
+  Chat, Dashboard and benchmark execution modules. Both revisions pass the real
+  Git registry-boundary smoke in disposable temporary directories; the earlier
+  run under `.local` failed because that ancestor intentionally selects a private
+  registry classification. The failure is retained as fixture-placement evidence.
+- **Cost qualification:** 30 interleaved base/head pairs for each of four
+  help/read workloads on both source and wheel yield 480 samples in 416.7s;
+  study setup/compatibility/profiling takes another 278.1s, excluding earlier
+  environment/wheel preparation and tests. On macOS arm64/Python 3.13.5 with
+  identical dependencies, precompiled bytecode and warm filesystem caches,
+  fresh-console help medians fall from 1.536–1.609s to 0.100–0.103s; registry
+  reads from 1.584–1.631s to 0.301–0.310s, and boundary reads from 1.542–1.612s
+  to 0.222–0.225s. Median RSS falls from about 91–92 MiB to 16–30 MiB.
+  Both help closures fall from 1,158 to 9 LoopX modules; registry/boundary reads
+  fall to 148/44. The PR records per-workload median/p95, CPU, separate audit
+  open counts and unchanged output bytes. No Node starts/IPC or Python-audit
+  socket events are observed; boundary reads keep their three Git queries.
+  Warm-cache block I/O is zero, while exact bytes read and native activity
+  outside the audit remain unknown. These results qualify local CLI cost
+  reductions, not portable D6 limits, full preparation/model costs or adoption.
+- **Validation and remaining work:** changed-file lint passes. The CI lint scope
+  still fails on the baseline-existing F841, whose repair is already proposed
+  separately; this result is not waived. Source and wheel evidence does not
+  upgrade an installed host. M1/#8011, full R0/V10, R1's real managed Turn,
+  context/model composition, split installation, adoption and complete costs
+  remain open. No D2/D5/D6/D3, default or authority decision changes. The related
+  bounded refactor shares the existing grammar and inspection adapter; larger
+  support/control extraction remains outside this slice.
+### 2026-11-06 — Selected Turn host loading seam
+
+Following the generic-cli/SQLite candidate in
+[#8180](https://github.com/loopx-project/loopx/pull/8180), the source proposal
+`9b80cf7d6` defers DSH builders at `turn_run_once` until a caller selects DSH
+or explicitly requests their established exports. Named imports, original
+builder identity, static types, `dir()`, star imports and the CLI's builder
+patch points remain available. The existing host/authority owners are reused;
+this does not select a minimal preset or adopt D2/D5.
+
+- **Observed delta:** the real generic-cli/SQLite task path loads 533 LoopX
+  modules instead of 538 at `62e234c93`. The five removed modules are
+  `turn_dsh_host`, `turn_driver.host_candidate`, `dsh_goal_mode` and its
+  `host_failure_map`/`turn_host_adapter`. No module is added. The cold-import
+  oracle fails at the baseline and passes at the proposal; the existing DSH
+  CLI fixture also proves the public builder patch point is used.
+- **Real-path parity:** the same private harness runs ordinary completion,
+  interruption after typed host-result persistence, original-journal resume
+  and committed replay on isolated SQLite fixtures at both revisions. Each
+  fixture ends with one host invocation/attempt, one writeback and one debit;
+  replay repeats none. Independent argv validators accept identical artifact
+  bytes. Each arm uses an isolated native broker whose shutdown and OS exit are
+  verified. This remains deterministic transport evidence, not model-host V4
+  or normal hard-lease V2 qualification.
+- **Observed costs:** one ordinary instrumented invocation per revision records
+  2.962 → 3.169 seconds, parent CPU 0.737 → 0.775 seconds and parent peak RSS
+  65.6 → 64.6 MiB; output remains 3,474 bytes. Waited-child CPU is
+  0.567 → 0.599 seconds. Cache, run order and competing work are not controlled;
+  these observations establish neither a latency improvement nor a regression
+  threshold. Broker RSS observations and waited-child usage do not measure
+  complete tree peaks, full wire/context bytes or model cost. The loading delta
+  is small; long-horizon benefit and D6 qualification remain unproven.
+- **Historical validation limits at `bc59a9ed4`:** the wider source selection records 596 passed and one
+  failed preview cold-import test; the baseline independently fails the same
+  test because `host_bridge_transport` eagerly imports
+  `extensions.process_runtime`. Owner-scoped mypy with `--follow-imports=skip`
+  reports the same 29 diagnostics at both revisions after line normalization;
+  it is not the full configured mypy suite. Neither failure is waived or
+  relabeled as passing. The process-helper seam below repairs that preview
+  failure in the same author proposal while retaining the type-check limitation.
+- **Remaining:** independent review, required validation and exact-head merge
+  readiness still govern adoption. Opt-in minimal selection, D2/D5 decisions,
+  full R0/V10/R1, hard-lease/context/model parity and split installation remain
+  open; the separate #8011 status proposal retains its limits. No authority,
+  provider, default, installed-host or release change is introduced.
+
+### 2026-11-06 — Preview process helpers remain with execution
+
+The follow-on runtime proposal `a44e27d96` repairs the unchanged preview import
+oracle. Deferring the bridge helpers first exposes a second eager import in
+`doctor_git`; both adapters now resolve the existing `process_runtime` owner
+at execution/cleanup or explicit import. Named/star imports, original function
+identity, static aliases, `dir()` and public patch points remain compatible.
+The TypeScript Host lifetime and process/permission decisions do not move.
+
+- **Observable result:** importing the preview command loads 337 LoopX modules
+  instead of 338 at `bc59a9ed4`, removing only `extensions.process_runtime`.
+  Successful real Git reads likewise leave cleanup unloaded. Actual generic-cli
+  execution still loads 533 modules in both arms because it needs those helpers.
+  This fixes a loading boundary; it establishes no speedup or long-horizon benefit.
+- **Real paths:** the same isolated SQLite harness passes ordinary completion,
+  typed-result interruption, original-journal recovery and committed replay at
+  both immutable runtime revisions. Artifacts remain identical; each fixture
+  has one host invocation/attempt, writeback and debit, with no replayed effect.
+  Both owned brokers stop with verified OS exit. Real bridge send/cancel,
+  backpressure, deadline and unconfirmed-cleanup cases retain their behavior;
+  real Git timeout/terminal cancellation retire the query's helpers. A cleanup
+  error retains the unknown diagnostic through the existing patch point.
+- **Limits:** seven Windows Job Object cases are skipped on macOS. One combined
+  validation attempt fails because the Git fixture's hook did not start within
+  its existing budget; the isolated Git selection subsequently passes without
+  changing that budget or oracle. Owner-scoped mypy checks all three touched
+  loading adapters and retains the same 29 diagnostics at base and proposal.
+  Full configured mypy, packaged/split installation, minimal selection, D2/D5,
+  complete R0/R1/V10, hard-lease/context/model parity and full-cost benefit remain
+  unqualified. Independent exact-head review and required validation still govern
+  adoption; the historical failures above remain historical failures.
+
+### 2026-11-06 — Paired cost campaign remains unqualified
+
+The bounded campaign at `a9485073f` versus `86d9c542d` produces useful negative
+evidence, not an attributable speedup. It ends at the frozen 20-minute sampling
+wall limit with 499 accepted observations: eight source groups have 30 pairs
+each; wheel JSON-version has nine pairs and one unmatched candidate observation.
+The other wheel groups were not sampled. The original criteria and every
+observation remain retained; neither the cap nor the incomplete groups become
+a passing qualification. Later integration of target `cd677182c` is outside
+these immutable measurements.
+
+The experiment uses macOS arm64, CPython 3.13.5, Node 26.0.0 and the real
+Node-owned SQLite 3.53.1 backend. Source and disposable monolithic `loopx` 2.2.0
+wheel environments have the same 57 dependency versions and verified import
+provenance. The public entrypoint exercises JSON version, selected
+`performance-diagnosis` help, status, quota admission and deterministic
+generic-cli work on the existing `_write_live_fixture(provider="sqlite")` owner.
+Order is fixed: source before wheel, that command order, cold before warm,
+alternating baseline/candidate order by pair. Each task has fresh synthetic
+state. Cold uses a fresh Python process and retired owned broker; warm uses a
+fresh Python process and retained broker. Filesystem caches are uncontrolled
+and bytecode writes are disabled; this is not a cold-disk claim.
+
+**Cache limitation:** existing bytecode was not normalized. A subsequent
+inventory finds 7 versus 1,241 LoopX `.pyc` files and 2 versus 344 dependency
+`.pyc` files in the source arms. JSON version loads the same 1,157 LoopX modules
+at both revisions; its parent read-open census is 2,402 versus 1,253. This
+invalidates attribution of the observed source reductions to the five-module
+loading change. The numbers below describe these cache conditions only.
+
+| Source operation | Broker condition | Baseline seconds, median / p95 | Candidate seconds, median / p95 |

+
+- **Covered costs:** cold task CPU for the target and waited descendants is
+  1.769 / 1.832 versus 1.283 / 1.388 seconds, median / p95; their maximum RSS
+  is 79.2 / 87.4 versus 75.5 / 78.7 MiB. Separate broker CPU is 0.720 / 0.780
+  versus 0.735 / 0.800 seconds, with end RSS 126.6 / 129.7 versus
+  128.3 / 133.5 MiB. These are not a concurrent tree peak or complete CPU ledger.
+  Outputs remain 81, 325, 21,829, 23,795 and 3,557 bytes for the five operations.
+  One-minute host load ranges from 5.00 to 14.42; this is a named-host observation.
+- **Separate instrumentation:** task loading remains 538 → 533 in source and
+  wheel. Cold task parent read/write-open counts are 2,179/284 → 1,643/284 in
+  source and 2,184/284 → 2,173/284 in wheel. All four captures make 238 local
+  IPC connections; covered socket send/receive bytes are 895,335/391,794 and
+  895,339/391,794 in source, 894,790/391,543 in both wheels. These cover the
+  observed Python sockets, not all context, transport or descendant I/O.
+  A separate source cold-task audit records parent/waited-child CPU
+  1.234/0.560 → 0.802/0.582 seconds and maximum RSS
+  88.7/75.3 → 63.4/75.4 MiB; these instrumented samples are not timing evidence.
+  The existing performance-diagnosis recipes inspect separate Pyinstrument
+  and actual Node-worker CPU profiles. Parent waits, workspace capture and
+  reads, and worker startup/retirement remain investigation leads; profile
+  elapsed/idle weights do not enter the timing table. Full JSON version uses
+  the full parser/export graph, while `--version` loads two LoopX modules.
+- **Semantic readback:** all sampled tasks independently accept the same eight
+  squared integers. Source and wheel at both revisions pass ordinary committed
+  replay, interruption after typed-result persistence, original-journal resume
+  and replay. Each accepted fixture has one host attempt/invocation, writeback
+  and debit; replay repeats none. Dropping the last square makes all four
+  independent validators reject, with one dispatch and zero writebacks/debits.
+  Owned brokers finish with OS PID-exit readback. One seed shutdown initially
+  targets a different interpreter-alias fingerprint; its failure is retained
+  and recovery uses the verified owned locator, without touching host state.
+- **Complete-cost limits and next work:** setup/orchestration is 888 seconds,
+  including 194 seconds of fixture preparation and a 98-second successful
+  preflight; unsuccessful bundle-build, invocation and preflight attempts remain
+  failures. Sampling target elapsed totals 1,001 seconds inside the 20-minute
+  wall cap. Separate semantic validation takes 39 seconds; artifact rejection
+  plus diagnosis/cleanup recovery takes 184 seconds; the instrumented census
+  takes 108 seconds, and task/version profiling 58/20 seconds. Subsequent
+  authoring/tool/model costs, complete native/thread work and full-tree peaks
+  remain incompletely covered. Both wheels contain 1,997 files and
+  approximately 8.9 MiB compressed; no split install is qualified. The next
+  cost experiment must match bytecode conditions and choose a feasible
+  representative source/wheel corpus from measured setup and invocation costs
+  before freezing it. Further loading edits await that comparison. R0/V10,
+  R1/minimal, D2/D5/D6, I3/D3, model/context/hard-lease and installation gaps
+  retain their existing owners and gates; this checkpoint closes none of them.
+
+### 2026-11-06 — Matched-bytecode representative cost checkpoint
+
+A new frozen comparison of `546c08c0d3f22358ef09b13e69f7edaa806121b8`
+and `0df5ad7921faab3b9ab8ec809f2fd71060692cce` completes all six selected
+source/wheel groups, each with 30 interleaved pairs: 360 accepted observations
+in 948.573 seconds, within the unchanged 1,200-second sampling cap. E7 remains
+an incomplete, cache-confounded experiment; these are separate observations.
+The measured proposal includes target main through `546c08c0d`. Later target
+integration is outside this immutable cost comparison.
+
+The environment remains macOS arm64, CPython 3.13.5, Node 26.0.0 and real
+Node-owned SQLite 3.53.1. All four source/monolithic-wheel environments have
+verified provenance and identical 57 dependency versions. Before freezing,
+each arm compiles stdlib, dependencies and all 1,421 LoopX Python sources into
+an owned `PYTHONPYCACHEPREFIX`; timestamp-header inventories find no missing or
+invalid own/dependency caches. Relative source sets match within each
+distribution. Inventories and frozen harness hashes remain identical after
+sampling, recovery and profiles. Targets disable bytecode writes. Source runs
+before wheel, selected help before task, cold before warm; even pairs use
+baseline/candidate order and odd pairs reverse it. Every invocation has fresh
+Python; cold retires the owned broker and warm retains it. Disk cache remains
+uncontrolled. One-minute host load ranges from 8.35 to 88.73; retain every tail
+observation, without attributing the source cold p95 difference to the code.
+
+| Selected operation | Broker | Baseline seconds, median / p95 | Proposal seconds, median / p95 | Median paired proposal minus baseline, seconds |
+| --- | --- | --- | --- | --- |
+| Source help | absent | 0.136 / 0.193 | 0.138 / 0.168 | +0.0010 |
+| Source SQLite task | cold | 3.579 / 5.997 | 3.617 / 9.234 | -0.0195 |
+| Source SQLite task | warm | 2.673 / 3.019 | 2.657 / 2.979 | -0.0602 |
+| Wheel help | absent | 0.087 / 0.107 | 0.083 / 0.116 | -0.0033 |
+| Wheel SQLite task | cold | 3.722 / 4.266 | 3.663 / 4.430 | -0.0847 |
+| Wheel SQLite task | warm | 2.707 / 3.111 | 2.797 / 3.156 | -0.0457 |
+
+The p95 uses nearest rank. Median paired differences and differences of arm
+medians are different statistics. No material latency or CPU benefit is
+demonstrated: arm medians and tails have mixed directions, and task CPU remains
+similar. These data qualify the representative comparison's completion and
+semantic parity, not a speed threshold, full V10 or long-horizon benefit.
+
+| Task path | Target plus waited descendants CPU seconds, median (base → proposal) | Target/waited peak RSS MiB, median (base → proposal) | Owned broker CPU seconds, median (base → proposal) | Broker end RSS MiB, median / p95 (base → proposal) |
+| --- | --- | --- | --- | --- |
+| Source cold | 1.311 → 1.325 | 75.75 → 75.58 | 0.770 → 0.775 | 127.9 / 134.8 → 128.6 / 133.5 |
+| Source warm | 1.235 → 1.226 | 76.15 → 76.16 | 0.180 → 0.185 | 146.5 / 148.4 → 129.8 / 148.7 |
+| Wheel cold | 1.353 → 1.369 | 75.94 → 76.56 | 0.805 → 0.810 | 129.5 / 134.4 → 130.1 / 134.1 |
+| Wheel warm | 1.273 → 1.260 | 76.05 → 76.69 | 0.190 → 0.180 | 100.4 / 136.3 → 101.4 / 140.2 |
+
+These RSS observations are not concurrent process-tree peaks; warm broker
+end RSS also reflects its retained lifetime. Help target/waited median RSS is
+17.56–17.85 MiB and median CPU is 0.046–0.056 seconds. Uninstrumented stdout is
+325 bytes for help, 3,557 for source tasks and 3,550 for wheel tasks in both
+arms; stderr is empty. Target/waited block-I/O counters do not measure all
+broker/native I/O.
+
+Separate instrumentation confirms task loading 538 → 533 in both distributions,
+with only the previously named five DSH modules removed; help stays at 12.
+Parent read-open counts are source cold 1,680 → 1,675, source warm 1,269 → 1,264,
+wheel cold 1,683 → 1,677 and wheel warm 1,272 → 1,267. Task write-opens stay at
+284 cold and 279 warm, with 238 observed parent local socket connections.
+Covered task send/receive bytes range from 893,698–894,864 / 392,608–392,859;
+the source proposal removes five send bytes and wheel bytes are unchanged.
+Help opens 31 files in source and 32 in wheel, with no writes or socket traffic.
+Instrumented task parent CPU is 0.635–0.774 seconds and peak RSS 62.3–65.5 MiB;
+waited-child CPU is 0.528–0.573 seconds and peak RSS 76.1–78.6 MiB. These single
+captures are a census, separate from the repeated timing results.
+
+The same isolated real SQLite fixtures at all four variants pass ordinary
+committed replay, interruption immediately after typed-result persistence,
+original-journal recovery and committed replay. Independent squared-integer
+artifact/transition oracles retain identical artifact bytes and one host
+invocation/attempt, one writeback and one debit. Resume does not redispatch;
+replay repeats no effect. Removing the final square produces exit 1 / failed
+with one dispatch and zero writebacks/debits in every variant. All owned
+brokers have shutdown/OS-exit readback; no experimental broker remains live.
+
+Setup/orchestration costs 1,018.786 seconds, including overlapping build,
+installation, fixture and cache work; those phases must not be summed.
+The separate rejection phase costs 16.056 seconds, instrumentation 39.116 and
+eight parent/actual-Node profile captures 54.880. Recovery/replay target time
+is recorded separately; its complete orchestration cost remains uncovered.
+Existing `performance-diagnosis` recipes report workspace capture, journal
+checkpoints, Git probes and quota preparation among Python observations; Node
+profiles include startup, request dispatch, idle and retirement. Sampled stack
+weights are neither benchmark latency nor proof of a root cause; inclusive
+weights, warmup and retirement cannot be added as task savings. Full context
+and process-tree/native/thread/model costs remain unknown. Monolithic wheels
+remain approximately 8.9 MiB; this does not qualify split installation.
+
+**Evidence-conditioned next action:** retain the tested compatibility/loading
+seams, and stop expanding these helpers for an unproven speedup. Prioritize a
+bounded characterization of the existing full-parser/export closure or the
+measured workspace/journal/bridge owner, then require a new matched real-path
+comparison before adopting a performance change. This checkpoint creates no
+new owner, budget, preset or default. R0's complete census, R1/minimal,
+D2/D5/D6, I3/D3, hard-lease/context/model and split-install acceptance remain
+open; independent exact-head review and required validation govern adoption.
+### 2026-11-07 — Governed CLI composition cost and archived closeout boundary
+
+The complete small-state CLI sequence is compared on main
+`8e86f173f08bd55eb833d8cdf42360f93bf989fe` and a private experimental overlay of
+#8240 at `4df990c9e66465171f980176fba4e3602d41f826` plus #8243 at
+`668bed2f03a274f273d39c187121a1a4ede67165`. Only their seven production Python
+paths enter the candidate. The independently installed monolithic wheels have
+verified source bytes for 1,836 runtime resources each, 1,998 total files and
+approximately 8.91 MiB compressed. All environments use CPython 3.13.5,
+Node 26.0.0, real Node-owned SQLite 3.53.1 and the same 57 dependency versions
+on macOS arm64. This overlay is an author experiment; it changes neither the
+installed host nor a shipped preset, authority provider or public runtime.
+
+Inputs, code/resource/wheel hashes, workload, cache policy, instrumentation,
+serial pair order, sampling and interpretation are frozen before sampling.
+Each CLI invocation has fresh Python, an empty owned bytecode-cache prefix and
+bytecode writes disabled. Each episode starts its own cold Node service at
+prequota and reuses it for subsequent phases; compile-cache and temporary roots
+are independent. Disk cache and concurrent host load remain uncontrolled.
+Pairs alternate baseline/candidate order. The 1,500-second cap includes fixture
+setup, execution, teardown and sampling orchestration. Pilot, negative-case,
+packaging and instrumented-census costs are recorded separately.
+
+Each fixture uses ordinary hard-lease claim/admission, a separate Git worktree,
+complete contiguous native initial reads, an independently verified JSON sum
+artifact (`45`), Todo completion, fresh evidence-linked Vision/writeback, one
+spend, terminal result/readback and exact completion/writeback/spend/terminal
+retries. Global synchronization and external sinks are explicitly suppressed;
+standard fanout is outside this experiment. The small state has one active
+Todo; large state adds 100 completed background Todos with substantial text.
+Large-state failures remain failures and do not become accepted cost samples.
+
+All 60 planned observations finish in **1,164.996 seconds**, within the unchanged
+cap: 52 small-state episodes complete and eight large-state episodes retain the
+same terminal failure. Code, script and freeze inventories remain unchanged.
+Small-state groups have 8/6/6/6 serial interleaved pairs; large groups have one
+pair each and qualify only the observed compatibility failure.
+
+| Small-state path | Pairs | Baseline seconds, median / p95 | Candidate seconds, median / p95 | Median paired difference, seconds | Exploratory 95% percentile interval |
+| --- | --- | --- | --- | --- | --- |
+| Source / Sqlite | 8 | 16.942 / 17.173 | 14.986 / 15.399 | -1.806 | -2.156 to -1.669 |
+| Source / File | 6 | 16.751 / 17.036 | 14.725 / 14.917 | -2.086 | -2.159 to -1.875 |
+| Wheel / Sqlite | 6 | 17.066 / 22.878 | 15.169 / 19.378 | -1.932 | -5.246 to 2.348 |
+| Wheel / File | 6 | 16.689 / 17.454 | 14.801 / 15.195 | -1.917 | -2.491 to -1.553 |
+
+The p95 uses nearest rank and is the observed maximum at these sample sizes;
+it is not a tail bound. The interval uses 10,000 fixed-seed paired resamples.
+Differences of arm medians and median paired differences are distinct. Arm
+medians improve approximately 11–12%; wheel/SQLite's interval crosses zero and
+retains both directions of tail variation. This is scoped evidence for the
+small-state path, not a universal latency threshold or long-horizon benefit.
+
+| Small-state path | Target plus waited descendants CPU seconds, median (base → candidate) | Maximum per-invocation target/waited RSS MiB, median (base → candidate) | Owned broker CPU seconds, median (base → candidate) | Broker end RSS MiB, median (base → candidate) |
+| --- | --- | --- | --- | --- |
+| Source / Sqlite | 10.536 → 9.190 | 126.60 → 90.02 | 0.767 → 0.775 | 126.59 → 125.28 |
+| Source / File | 10.507 → 9.101 | 127.77 → 87.15 | 0.716 → 0.702 | 126.77 → 126.70 |
+| Wheel / Sqlite | 10.782 → 9.289 | 134.83 → 91.51 | 0.799 → 0.797 | 125.77 → 126.91 |
+| Wheel / File | 10.606 → 9.348 | 132.01 → 88.21 | 0.729 → 0.723 | 127.97 → 127.77 |
+
+RSS is the maximum of individual CLI invocation peaks, not a concurrent
+process-tree total. Broker counters exclude retirement and use Darwin's
+calibrated timebase. Default SQLite target/waited CPU falls about 13–14%; broker
+CPU/RSS have no consistent improvement. Source/SQLite prequota median falls
+3.425 → 1.468 seconds; guard remains 1.845 → 1.863 seconds and becomes the
+largest candidate phase. Wheel/SQLite prequota is 3.463 → 1.581 seconds, while
+guard is 1.844 → 2.033 seconds. The gain is concentrated in fresh Python
+prequota loading, not faster authority execution.
+
+Setup and retirement medians across groups are 2.15–2.29 and 0.36–0.40 seconds.
+Including setup, teardown and driver overhead, source/SQLite median is
+20.238 → 18.146 seconds and wheel/SQLite 20.393 → 19.793 seconds. Independently
+building/installing the two wheels costs 43.881 seconds. Setup, validation,
+recovery and census may overlap and must not be summed. Preparatory authoring,
+complete native/thread/process-tree I/O, model tokens, model/human costs and
+long-horizon outcomes remain incompletely measured. Kernel-observed broker disk
+writes stay at roughly 5.85 MiB per SQLite episode and 220 KiB per File episode;
+those counters are not total filesystem traffic.
+
+Across all 60 observations the artifact bytes, original bindings, complete
+settlement obligations, one writeback and one debit agree. Required native
+initial bodies are 23,498–24,442 bytes for small states; `bytes / 4` is only a
+rough token proxy, not tokenizer output or proof of model retention. The
+candidate's extra 85 source / 165 wheel bytes are path/reference presentation;
+normalized settlement obligations compare clause for clause without deletion.
+
+With 101 Todos, ordinary completion automatically archives the selected Todo
+at its original early presentation position, together with 90 background
+Todos. Validation, writeback and one spend commit, but the later original-Turn
+`todo complete --no-follow-up` rejects with `todo_archived`. All four
+source/wheel × File/SQLite pairs reproduce this on both arms. No failed episode
+is counted as accepted or used to claim a complete large-state speedup. The
+existing `todo_terminal_lifecycle.ts` and `todo_archive_selection.ts` owners
+must reconcile archival with original-receipt closeout. Related #5677 already
+owns freshness/terminal recovery; its published 0/1/4-history matrix does not
+qualify this automatic-archive case. Preserve fresh archived-Todo, changed
+actor/lease/evidence and duplicate-effect refusals when extending that owner.
+
+A separate census over all eight source/wheel × File/SQLite variants preserves
+invalid Vision/workspace refusals. Four additional failure checks per variant
+cover missing Node admission, missing provider, mismatched capture digest and
+released-claim completion: no writeback/debit commits. Prequota's soft failure
+continues to quota; it does not grant admission. These checks take 69.559 seconds;
+the instrumented census takes 90.358 seconds, with overlap between phases.
+Every sampled/census broker has observed shutdown and OS exit; pilot's initial
+wrong-source retirement/pending wait remains in history and was subsequently
+resolved in its owned namespaces.
+
+Excluding the census's two extra refusals, complete-episode RPCs are 271 → 270
+in every variant; spend alone is 83 → 82. Observed receive traffic is
+999,060–1,004,527 → 966,984–972,825 bytes; send traffic is
+1,025,077–1,037,023 → 1,026,956–1,040,098 bytes. Extra send bytes reflect the
+longer candidate paths. Parent read-opens are 13,532–13,561 → 11,700–11,728;
+write-opens 285 → 284. Instrumented prequota module graphs are source
+1,404 → 480 and wheel 1,403 → 479, including instrumentation imports; these
+are not uninstrumented loading budgets. Cold Node/readiness takes 0.217–0.249
+seconds and version probing 0.026–0.032 seconds in the census. Single census
+timings do not establish a repeated latency gain; socket coverage and open
+counts do not include all native/broker I/O.
+
+**Evidence-conditioned next action:** carry the archive case to the existing
+terminal/freshness owner and #5677 integration before qualifying the full
+large-state lifecycle. Preserve the original operation/read/receipt identity
+and every refusal boundary; do not change archive policy merely to pass this
+workload. Then characterize the remaining `quota should-run` parser/loading and
+shared projection caller before selecting another performance change. The
+small-state data support continued exact-head review of #8240/#8243, not merge
+or installed-host adoption. Retain I3 for at least one minor release and keep
+M1/#8011, full R0/V10/R1, D2/D5/D6/D3, context/model/split-install, actual adoption
+and complete-cost acceptance open. No new budget, preset, provider or authority
+is introduced.
+
+For a source replay, fetch the exact PR heads and apply only the production
+`loopx/` diffs from their recorded merge bases (`79665b97a0a453380da02e15b1b62eee895147df`
+and `97cc1e0c40e766c73193b8077526a7f565dc561b`) to an isolated archive of the
+baseline. `uv sync --extra test` supplies the console. Build the two monolithic
+wheels independently with `uv build --wheel`; validate the Chat bundle through
+its existing owner before building. Reuse the source fixtures in
+`tests/control_plane/test_quota_settlement_cli.py`: author the synthetic Goal
+and background Todos before `_initialize_fixture_authority`, select File or
+SQLite and `hard_lease`, and use ordinary claim for execution. Declare the
+artifact write scope in both the Todo and Goal boundary, and use the existing
+Git-fixture helper plus a distinct worktree. Scope every command below to that
+fixture's registry/runtime and worktree; the guard supplies the full read and
+recovery commands. Keep the same Goal, Agent, Todo, Turn and claim operation:

+
+Declare the fixture's observed shell, filesystem-write, network and evidence-poll
+capabilities on admission/writeback/spend; use the actual installed console for
+generated reader commands. Repeat completion, writeback, spend and terminal with
+unchanged arguments. Missing Node uses an isolated PATH, missing provider an
+empty disposable runtime, stale source a mismatched capture digest, and stale
+claim a normally released lease. These cases must refuse before writeback/debit;
+invalid Vision/workspace also remain refusals. The temporary measurement harness
+and raw captures stay private; this recipe describes the repeated workload and
+its oracles, not a distributed benchmark runner or public reproduction receipt.
+
+### 2026-11-07 — Original-Turn closeout survives automatic Todo archival
+
+The complete CLI comparison in #8257 exposed a lifecycle failure with 101
+synthetic Todos. Fresh source-console reproductions on `4a33eb4b5` retain
+`todo_archived` on both File and default SQLite after ordinary completion,
+durable writeback and one quota debit. The frozen comparison remains unchanged;
+these failed episodes are not accepted latency samples.
+
+The proposed repair stays in `todo_terminal_lifecycle.ts`. Its existing
+same-Turn fence and exact ordinary-completion receipt verification also qualify
+an archived Todo's closeout before the active-only rejection. One local helper
+owns both active and archived parent checks. Original claim/lease, task digest,
+validation declaration/receipt and provider CAS checks remain in force; archive
+selection and retention thresholds are unchanged. This permits only the
+original completion's terminal phase, without reopening archived work.
+
+Real File/SQLite console fixtures now complete the large-state sequence and
+replay completion, writeback, quota spend and terminal closeout with one debit
+and an unchanged independently verified JSON result. The durable CLI regression
+uses a real validator and ordinary hard-lease claim: premature settlement,
+unrelated archived work, another actor, claim or Turn, and changed completion
+intent are refused. Terminal closeout retains the original passed validation
+receipt, first completion time and archive state without rerunning the validator.
+Existing provider conformance retains source/digest, validation, lease and replay
+checks; an isolated real PostgreSQL suite qualifies its shared owner separately.
+
+The author proposal also integrates main `abf144202` (#8161), whose explicit
+Goal-scoped checks do not gate local Todo completion. The archive regression
+covers a failed Goal commitment alongside the local validator: ordinary and
+terminal completion still preserve the original receipt and one debit, never
+rerun the Goal checker, and leave the overall check failed. This is author-side
+integration coverage; it does not replace independent review or reviewed-repair
+wheel qualification.
+
+Independent review of #8264 at `12627eff8` found that changing only `--evidence`
+could replace the archived Todo's accepted artifact while returning the old
+validation receipt. All four File/SQLite × Goal-check fixtures reproduce this
+failure on that head. The revision integrates target main `10f66ec5e` and rejects
+different supplied evidence before archived closeout. Its new archived-closeout
+receipt also retains the accepted evidence, so a changed retry cannot bypass the
+check through receipt recovery. Omitted or empty evidence with a valid completion
+note keeps the original value; the CLI's completion-note requirement still applies.
+Historical fingerprints and older receipts remain compatible; active
+completion behavior is unchanged. The regression checks canonical evidence,
+original validation and completion time, and once-only validation/writeback/debit
+before and after terminal replay. The earlier reviewed head remains unaccepted.
+The revised `7ec8d19b9` received an independent
+[APPROVE review](https://github.com/loopx-project/loopx/pull/8264#pullrequestreview-5811807012)
+and #8264 merged as `172d80d63`.
+
+Qualification against target main `32167518b` now covers both the source console
+and a freshly built, isolated monolithic wheel. The Chat bundle was built and
+verified through its existing owner before wheel construction. All four
+File/SQLite × source/wheel episodes contain 101 synthetic Todos and use the real
+console, ordinary hard-lease claim and an independently verified JSON artifact.
+After the single committed debit, the fixture stops only its own Effect processes;
+new console processes recover the original terminal result through a restarted
+runtime. Canonical readback retains the accepted evidence, first completion time
+and archived state. Completion, writeback, debit and terminal retries retain four
+committed receipts and one debit; changed evidence is refused before terminal
+commit and on replay. The final original-Turn guard reports no runnable work or
+execution attempt. Wheel console/import provenance is checked separately from
+the source fixture authoring environment.
+
+| Distribution / provider | Complete episode | Initial guard | Result |
+| --- | ---: | ---: | --- |
+| Source / File | 22.682 s | 2.148 s | Original result recovered; one debit |
+| Source / SQLite | 22.220 s | 2.219 s | Original result recovered; one debit |
+| Wheel / File | 20.929 s | 2.020 s | Original result recovered; one debit |
+| Wheel / SQLite | 24.205 s | 2.787 s | Original result recovered; one debit |
+
+These are single correctness episodes, including negative/replay checks and
+controlled process stops, on macOS with Python 3.13.5 and Node 26.0.0. They do
+not rerun the frozen paired cost study or establish a latency improvement.
+The original eight large-state failures and the earlier uncertainty remain
+historical evidence. Three isolated parser inputs also confirm source/wheel
+acceptance of an emitted archive pointer while unexpected prose and mismatched
+region markers remain refusals. The older reader's pointer failure is preserved;
+this comparison neither changes the grammar owner nor upgrades an installed host.
+
+This qualifies the repaired large-state source/wheel closeout and controlled
+Effect restart boundary. The remaining guard loading/shared-projection cost
+profile and complete comparison stay with the existing work. Abrupt-interruption
+and model-host V4 recovery, split installation, full R0/V10/R1, M1/#8011,
+D2/D5/D6/D3, context/model, actual adoption and complete-cost benefit remain
+open. I3 remains at least one minor release.
+
+### 2026-11-07 — Guard loading and settled-replay diagnosis
+
+Source-console diagnosis at `6c10e61ad` reuses the real 101-Todo hard-lease
+episode above, with isolated File/SQLite authority and owned Effect processes.
+Five additional episodes preserve accepted evidence, original completion time,
+four committed receipts and one debit through controlled restart; changed
+evidence and renewed execution of the settled Turn remain refusals. Only guard
+and immutable-context reads are profiled. These are single diagnostic
+observations, including profiler overhead, rather than paired performance runs.
+
+| Bytecode condition / provider | Profiled guard | Import cumulative | Traced runtime requests | Request elapsed sum | Loaded LoopX modules |
+| --- | ---: | ---: | ---: | ---: | ---: |
+| Bytecode disabled / SQLite | 3.012 s | 2.281 s | 89 | 0.370 s | 503 |
+| Bytecode disabled / File | 1.972 s | 1.255 s | 89 | 0.344 s | 503 |
+| Normal inherited bytecode / SQLite | 1.584 s | 0.845 s | 89 | 0.394 s | 503 |
+| Normal inherited bytecode / File | 1.465 s | 0.772 s | 89 | 0.342 s | 503 |
+
+The disabled-bytecode observations include 0.634 / 0.555 seconds in source
+compilation for SQLite / File; neither normal-bytecode observation invokes
+source compilation. Import, loader-read and compilation values are nested and
+must not be added. Bytecode conditions explain part of startup cost while the
+loaded graph remains unchanged. They do not correct or supersede the frozen
+comparison's failures. In a fifth normal-bytecode SQLite episode, the guard
+loads 503 modules with 89 traced requests, while the immutable context reader
+loads 68 modules with one traced request: profiled elapsed times are 2.140 /
+0.246 seconds, and request elapsed sums are 0.389 / 0.067 seconds respectively.
+This characterizes different required operations, not interchangeable paths.
+
+Runtime request elapsed includes Python transport, shared runtime work and
+provider work. It is an upper bound on the provider contribution within those
+traced requests, not a separate database measurement or complete service CPU.
+The source snapshot takes approximately 0.048–0.050 seconds in the four guard
+observations. The next cost investigation therefore prioritizes the loaded
+decision/status graph over a new provider or fingerprint optimization. Moving
+`quota_context` imports alone cannot eliminate work that the later status
+collector still requires; quota already omits presentation projections, and
+the immutable context reader already has its selected loading path.
+
+Real File/SQLite Monitor episodes also qualify the settled and closed replay
+identity when an independent sibling becomes due. Each original Turn retains
+one poll and zero debits, without dispatching its sibling. Through the public
+`configure-goal --quota-compute 0` entrypoint, pause still takes precedence and
+returns `quota_skip`. The initial probe changed legacy `status` fields instead
+of the typed activation or quota owner; its failed pause expectation is a
+fixture error, retained separately from the corrected checks.
+
+| Provider / replay phase | Profiled replay | Import cumulative | Traced runtime requests | Request elapsed sum | Loaded LoopX modules |
+| --- | ---: | ---: | ---: | ---: | ---: |
+| SQLite / settled | 1.135 s | 0.666 s | 68 | 0.150 s | 486 |
+| SQLite / closed | 1.149 s | 0.726 s | 62 | 0.157 s | 486 |
+| File / settled | 1.113 s | 0.713 s | 68 | 0.143 s | 486 |
+| File / closed | 1.128 s | 0.691 s | 62 | 0.149 s | 486 |
+
+The bounded next step stays with the existing quota/status and typed replay
+owners: identify which live facts and imports each decision actually needs,
+then remove unused loading or redundant shared requests with public-facade
+parity. A receipt-only early return is not yet qualified: current pause, scoped
+gates, independent pending intents, actor/lease/source checks and archived or
+closed lineage must survive. Any implementation still needs the same real
+source/wheel lifecycle and matched, unprofiled default-SQLite comparison;
+supported-backend correctness/recovery and required PostgreSQL qualification
+remain in force when affected. This diagnosis changes no production behavior,
+preset, budget, provider, authority or installed host. All earlier acceptance,
+adoption and complete-cost gaps remain open.
+
+### 2026-11-07 — Guard cost candidate selection and context transport composition
+
+An isolated source-console counterfactual defers three Monitor adapter imports
+until their functions are invoked. The 101-Todo SQLite lifecycle still retains
+the original artifact, completion time, four receipts and one debit. The guard
+loads 502 rather than 503 modules and still makes 89 traced runtime calls;
+only `todos.external_wait_contract` disappears. Monitor history lookup and
+quota accounting admission execute on the guard path, so their dependencies
+remain necessary. This rejects that import deferral as the next cost-reduction
+slice; the temporary wrapper is not a production or compatibility qualification.
+
+The existing context-transport candidates are separate from loading reduction:
+[#8286](https://github.com/loopx-project/loopx/pull/8286) at `efce6cb9c` skips
+inactive Anti-Entropy validation, and
+[#8290](https://github.com/loopx-project/loopx/pull/8290) at `9537687be` omits the
+governing source from status-only context validation. A temporary combined
+overlay against runtime base `32167518b` was exercised through four complete
+File/SQLite × base/overlay source-console episodes with 101 Todos. Accepted
+evidence, first completion time, controlled Effect restart, four committed
+receipts and one debit remain intact; evidence replacement and settled-Turn
+execution remain refusals. The combined source also passes 91 focused Python
+cases and 20 TypeScript cases with zero skips. The applied paths are restored
+after qualification; this creates no competing implementation or merge.
+
+| Provider | Traced guard calls, base → overlay | JSON parameter bytes, base → overlay | Loaded modules, base → overlay |
+| --- | ---: | ---: | ---: |
+| SQLite | 89 → 87 | 1,904,862 → 1,772,448 (−6.95%) | 503 → 503 |
+| File | 89 → 87 | 1,903,569 → 1,771,587 (−6.93%) | 503 → 503 |
+
+These single instrumented observations count the UTF-8 JSON parameters passed
+to the shared runtime. They exclude transport headers, retries, responses,
+startup and service CPU; they are not total wire bytes or a latency comparison.
+The SQLite status-only validation inputs total 134,868 bytes on base; the one
+remaining input is 2,045 bytes in the overlay. Immutable context and settlement
+owners remain in place. This independently confirms a bounded transport delta,
+without qualifying either candidate's merge, a combined wheel, installed-host
+adoption or complete task benefit. The frozen cost studies remain unchanged.
+
+The largest remaining guard parameter producers are `todo.context.page`
+(789,198 bytes across nine calls), `todo.quota_planning.project` (390,361 bytes)
+and `goal.vision_wait.project` (185,559 bytes), identical in the SQLite base and
+overlay. The next bounded investigation targets reuse of the canonical Todo
+source in those existing typed projection owners, before implementing one
+coherent source-read transaction. It must preserve source/provider revisions,
+actor/lease fences, complete exact reads, archive/replay lineage, pause/gates
+and pending intents. More leaf RPCs or lossy source-field pruning do not qualify
+the transaction cutover. Existing Goal-route work in #8123 and its unresolved
+performance holds remain separate. Full source/wheel correctness and a matched,
+unprofiled default-SQLite whole-path comparison are still required for a new
+implementation; all earlier milestone, adoption and complete-cost gaps remain.

+### 2026-11-06 — 发现路径集成与下一条可执行边界
+
+- **已集成：** [#8012](https://github.com/loopx-project/loopx/pull/8012)
+  于 11 月 4 日将提案 head `58442be4d` 合并为 `83f569178`。在独立准备的
+  `main` 版本 `62e234c93` 上，全部 23 个发现与受保护分发用例通过。复验命令：
+  `uv run --extra test python -m pytest -q tests/test_cli_entrypoint.py -k 'capability_discovery or capability_non_discovery'`。
+  这验证当前源码集成；此前安装 wheel 与成对性能证据仍绑定原版本和环境。本次
+  复验不证明已安装宿主或新 wheel 的资格。
+- **已解决的前置问题：** [#8054](https://github.com/loopx-project/loopx/pull/8054)
+  （`886f2cdff`）将 capture I/O 移出 settlement plan 的冷 import。
+  `uv run --extra test python -m pytest -q tests/architecture/test_control_plane_import_boundaries.py::test_settlement_plan_import_does_not_load_native_capture_io`
+  在 `62e234c93` 上通过。11 月 4 日的失败仍是历史证据；后续修复移除了这一
+  特定 import 阻塞。本版本没有重跑更广的套件或配置的 mypy，不能将此前结果改写
+  为当前通过资格。
+- **下一源码切片：** 刻画既有 `generic-cli` managed Turn 路径，使用 SQLite
+  authority 并关闭可选任务 hook，作为所选 D2/D5 装配的候选。复用 Turn、host
+  selector 与类型化 authority owner。`tests/test_loopx_turn_driver.py` 中既有
+  CLI 中断与 successor 重放测试可定位集成接缝，但不证明 minimal preset。
+  下一片必须明确实际依赖闭包，并通过隔离、能产生任务产物的宿主进程验证中断、
+  重启和独立验收后的结果回读，保留原身份且不重复已确认效果。确定性的本地宿主
+  可以验证其合成 transport 边界，不证明模型宿主或完整 V4 旅程。
+- **剩余：** 完整 R0/V10、M1/I3/D3、独立 status 提案 #8011、拆包安装与 R1
+  均未关闭。D2/D5 仍由 owner 决策；本候选不改变 preset、默认值、执行权限或
+  发布承诺。继续移动目录不构成下一条执行证据。
+
+### 2026-11-06 — generic-cli/SQLite 装配候选与恢复证据
+
+这是 D2/D5 候选及源码刻画，不是已批准的 preset。复用既有 Turn、宿主选择、
+authority 与 settlement owner。
+
+| 维度 | 候选／观察到的边界 |
+| --- | --- |
+| 安装 | 当前单体 `loopx` 源码 checkout；macOS arm64 上 Python 3.13.5、Node 26.0.0。test extras 只准备实验，不是最小安装；不证明拆分发行物或已安装宿主资格 |
+| 宿主 | 既有 `generic-cli`、`isolated-headless`，经 `--host-adapter-command-json` 使用 JSON stdio；一个确定性的本地任务产物进程和独立、受信 argv 验收器。该夹具无须模型 session 或 workspace/IM 服务 |
+| Authority | 经既有 TypeScript effect runtime 及本地 RPC 传输使用规范 SQLite，并复用 Turn journal、验收与结算。测试脚手架以 `soft_claim` shadow 初始化；不能仅靠这些证据证明正常 hard-lease 的 V2 一致性 |
+| 必需的逻辑内核 | Bootstrap／所选 CLI、TurnEnvelope 与宿主准入、当前 authority／stop／budget／claim 规则、journal／恢复、进程监督、独立验收和结果／结算回读。owner 与 standard 共享 |
+| 可选激活 | 夹具不启用任务 memory 或其他可选 hook，不运行模型任务或外部操作。加载 settings／policy helper 不证明激活，也不授权删除它们 |
+| 身份与恢复 | 使用 `--resume-turn-key` 恢复原 journal；该路径有意拒绝新的 `--turn-instance-id`。复用缓存中已确认的宿主工作；未确认工作及其他中断点继续由各自契约治理 |
+
+- **真实任务与恢复：** 真实宿主进程写出零至七的平方数，独立进程检查预先给定的
+  字面数组。正常路径和 typed host result 持久化后对所持 CLI 注入 OS `SIGKILL`
+  的路径，在各自隔离 SQLite 夹具中最终都只有一次宿主调用、一次 writeback 和
+  一次扣额。中断路径在重启前没有扣额；重启验收缓存结果，不再次调用宿主。随后
+  committed 重放报告没有重复 host／writeback／扣额／scheduler 效果。两条路径的
+  产物字节一致；没有对活跃项目状态注入故障。
+- **实际加载：** 产品版本 `62e234c93` 上，正常 Python 路径加载 538 个 LoopX
+  模块，涉及 21 个 capability 命名空间，不加载 `loopx.cli` 或 `loopx.chat` 树。
+  第二轮使用隔离的既有 runtime broker 和透明 Node module-load observer；其
+  bootstrap、执行与恢复加载 `control_plane` 下 231 个 TypeScript 文件和八个
+  JSON 文件。这是观察到的闭包，不是已批准的 core 成员。已核验私有 broker 的
+  身份、停止 ACK 和进程退出；没有停止共享服务。
+- **成本与限制：** 父进程插桩区分必需本地 RPC 与外部网络连接，后者观察为零。
+  正常调用观察到 34 个 Git 子进程、一个 Node 版本探测、一个 Node 宿主监督器和
+  一个 Python 验收器；监督器另行启动任务宿主。child／broker CPU 与 RSS、完整
+  wire／context 字节及模型宿主成本尚未测量。这些小规模插桩演练不是重复的成对
+  性能采样，不建立 D6 预算或长程收益证据。
+- **独立回归证据：** `tests/test_loopx_turn_driver.py` 中
+  `test_managed_start_interruption_preserves_reservation_and_attempt` 的六个
+  SQLite 用例，以及 `test_turn_run_once_cli_rejects_unproven_host_claim_before_writeback`
+  和 `test_turn_run_once_cli_replays_declared_successor_after_interruption` 均通过。
+  探针设置拒绝与产品失败分别保留：过宽网络 observer、错误的 host-request schema
+  及冲突的恢复 flags 已修正，不改生产代码、不放松权限，失败观察仍保留。
+- **下一 owner 变更：** `loopx/cli_commands/turn_run_once.py` 在选宿主前导入
+  DSH host builder，但调用点只在 `args.host == "dsh"` 分支。generic 路径因此
+  加载未选择的 `turn_dsh_host` 和 `dsh_goal_mode.turn_host_adapter`。先刻画既有
+  export／patch 点，再在其 owner 接缝延迟加载，并复验 generic／DSH／Codex 行为
+  与默认关闭一致性。命名空间数量本身不支持删除共享 policy helper。
+- **剩余：** opt-in minimal 选择、完整 D2/D5 采纳、hard-lease 与上下文 V2/V5
+  一致性、尚未确认的宿主工作期间中断、模型宿主 V4、完整 V10 与拆包安装资格仍
+  未关闭。不引入新 engine、provider、默认值、权限字段或 runtime self-merge。
+
+### 2026-11-07 — Heartbeat pre-quota 按需加载
+
+- **基线与 owner：**`79665b97a`。heartbeat builder 已在 external evidence polling
+  可用时生成 `heartbeat-prequota`。选择性 parser 复用原 heartbeat registrar，dispatch
+  放在现有 heartbeat transport 模块；完整 facade 显式传入原 runner、renderer 和全局
+  registry resolver patch points。显式／隐式路由、别名、格式、timeout、异常、降级返回和
+  controller 语义均已刻画；reconciliation／hook 顺序及 typed owners 保持原路径。
+- **源码与包证据：**新增 50 个 transport／加载／真实后端用例；四个独立核对的源码／
+  wheel console 各运行 22 个场景；16 个配置／降级 File／SQLite console 场景覆盖重放、
+  opaque 原工作保留和零 quota 扣费。删除 `continue_to_quota` 的 mutation 经同一公开
+  console oracle 在两种真实 store 上被拒绝。原 acknowledgement smoke 同时覆盖两个
+  CLI facade。完整源码选择初轮得到 378 pass、两个路由测试失败，精确基线同样失败。
+  fixture 改为读取原 digest-bound progressive capture，不重新准入；受影响文件随后
+  17 个用例全部通过。失败未豁免。聚焦 lint、配置内 mypy 和代码 canary 通过。
+- **配对本地成本：**macOS 27.0 arm64、Python 3.13.5、Node 26.0.0；相同依赖和合成
+  store，预编译 bytecode、全新 Python 进程、热文件缓存及复用的隔离 Node 服务。
+  每个 workload／distribution 30 个交错 base／head 配对，共 360 个样本，采样 339 秒；
+  study 准备／验证另计 260 秒。测量使用共享开发机，并非空闲机器实验。下表是含解释器
+  启动的墙钟 median／p95（秒）和进程 RSS 中位数（MiB）。
+
+| Workload / distribution | 基线 median / p95 | 候选 median / p95 | 基线 → 候选 RSS |
+| --- | --- | --- | --- |
+| `source/prequota-help` | 1.433 / 1.889 | 0.172 / 0.226 | 91.5 → 24.7 |
+| `source/prequota-file-off` | 1.494 / 1.927 | 0.545 / 0.667 | 92.0 → 47.0 |
+| `source/prequota-sqlite-off` | 1.547 / 1.977 | 0.507 / 0.640 | 91.9 → 46.3 |
+| `wheel/prequota-help` | 1.555 / 1.967 | 0.170 / 0.210 | 91.7 → 24.5 |
+| `wheel/prequota-file-off` | 1.545 / 2.155 | 0.536 / 0.650 | 91.7 → 46.7 |
+| `wheel/prequota-sqlite-off` | 1.397 / 1.866 | 0.531 / 0.667 | 92.0 → 46.9 |
+
+- **加载边界与完整成本限制：**help 的 LoopX 模块为 29，基线 1,158；默认关闭的执行
+  为 277，基线 1,160。Python open 观察由 1,292–1,312 降至 81–395；打开文件尺寸之和
+  是 footprint，不是实际读取字节。候选 help 的 user／system 进程 CPU 中位数为
+  0.04／0.02 秒，执行为 0.13–0.14／0.065–0.08 秒；基线为
+  0.40–0.42／0.16–0.185 秒。help 输出仍为 737 字节，JSON 执行仍为 827 字节。
+  独立 SQLite loopback profile 在两版均观察到发送 1,362、接收 668 字节；冷服务启动
+  Node version／server 两个进程，复用服务启动数为零。单次带 instrumentation 的冷／
+  热观察不能拆出 Node readiness 或 service CPU，相关成本未通过资格。初轮 IPC probe
+  误以为使用 Unix socket 而失败，改为 loopback instrumentation 后通过，未修改产品。
+  help p95 为 0.226／0.210 秒，超过提议的 0.200 秒目标；未晋升或重标该 D6 提议。
+- **剩余：**这是一条 R0／V1／V3／V10 caller 的作者提案，I3 至少保留一个 minor release。
+  完整 R0／V10、M1／#8011、R1、context／model、split-install、installed-host 恢复、
+  采纳和完整任务成本仍开放。Python 仅适配 transport，没有新增 decision owner、preset、
+  provider 或权限规则。最终 exact-head review／CI 仍是独立交付门，与这些本地观察分开。
+### 2026-11-07 — Registry 检查的选择性加载
+
+- **基线与边界：** `ac6296225`。`registry` 和 `registry-boundary` 使用现有
+  selected CLI 路由。共享注册器与传输适配器留在 `cli_runtime`；显式完整 CLI
+  通过 `support_control` 复用它们，保留原有检查函数与 renderer patch point。
+  Registry 解析、分类及 Git 判定仍归现有 owner。Python 在此只适配 CLI，不新增
+  决策 owner、provider 或 dispatcher 框架。既有导入与 I3 至少一个 minor release
+  的兼容窗口保持不变。
+- **兼容证据：** 源码 CLI 与 support ownership 的 197 个用例通过，包含新增的
+  26 个检查结果、拒绝与 patch-point 用例及两个 help 用例。独立的完整 CLI 加载
+  排除断言经同一公开入口，在不可变基线上失败、候选版本上通过。20 个成功与
+  拒绝请求在源码及独立安装的单体 wheel 控制台上保持输出、状态与异常语义一致。
+  Help 与读取路径在缺少 Node 时仍可用，并排除未选择的 Chat、Dashboard 和
+  benchmark 执行模块。两版本在一次性临时目录中均通过真实 Git registry-boundary
+  smoke；先前放在 `.local` 下的运行失败，因为该祖先路径会按既有规则选择私有
+  registry 分类。这次失败作为 fixture 放置证据保留。
+- **成本资格：** 源码与 wheel 各四条 help/读取路径，每条运行 30 对交替 base/head
+  样本，共 480 个样本，采样耗时 416.7 秒；研究准备、兼容验证及 profiling 另耗时
+  278.1 秒，不含此前环境、wheel 准备及测试。macOS arm64/Python 3.13.5、相同依赖、
+  预编译字节码和暖文件缓存下，新进程控制台 help 中位数从 1.536–1.609 秒降至
+  0.100–0.103 秒；registry 读取从 1.584–1.631 秒降至 0.301–0.310 秒，边界读取从
+  1.542–1.612 秒降至 0.222–0.225 秒。RSS 中位数从约 91–92 MiB 降至 16–30 MiB。
+  两条 help 的 LoopX 模块闭包均从 1,158 降至 9；registry/边界读取降至 148/44。
+  PR 记录逐路径 median/p95、CPU、独立 audit 的文件打开次数及未改变的输出字节。
+  未观察到 Node 启动/IPC 或 Python audit socket 事件；边界读取保留三次 Git 查询。
+  暖缓存块 I/O 为零，准确读取字节数及 audit 之外的原生活动仍未知。这些结果只限定
+  本地 CLI 成本改善，不建立可移植 D6 限值、完整准备/model 成本或采纳结论。
+- **验证与剩余工作：** 改动文件 lint 通过。CI lint 范围仍失败于基线已有的 F841，
+  其修复已另行提案；这里不豁免该结果。源码与 wheel 证据不升级已安装 host。
+  M1/#8011、完整 R0/V10、R1 的真实受管 Turn、context/model 组合、拆包安装、采纳
+  与完整成本仍开放。D2/D5/D6/D3、默认行为及权限判定均不改变。相关有界重构
+  共享既有 grammar 与检查适配器；更大的 support/control 提取不纳入本切片。
+### 2026-11-06 — 所选 Turn 宿主的加载接缝
+
+承接 [#8180](https://github.com/loopx-project/loopx/pull/8180) 的
+generic-cli/SQLite 候选，源码提案 `9b80cf7d6` 在 `turn_run_once` 延迟加载 DSH
+builder，直到调用方选择 DSH 或显式请求既有 export。命名 import、原 builder
+身份、静态类型、`dir()`、star import 与 CLI builder patch 点均保留。复用既有
+宿主／authority owner；这不选择 minimal preset，也不代表 D2/D5 已采纳。
+
+- **观察到的变化：** 真实 generic-cli/SQLite 任务路径加载 533 个 LoopX 模块，
+  基线 `62e234c93` 为 538。移出的五个模块是 `turn_dsh_host`、
+  `turn_driver.host_candidate`、`dsh_goal_mode` 及其 `host_failure_map`／
+  `turn_host_adapter`，没有新增模块。冷 import oracle 在基线失败、提案通过；
+  既有 DSH CLI 夹具还证明公开 builder patch 点被使用。
+- **真实路径一致性：** 同一个私有 harness 在两个版本的隔离 SQLite 夹具上运行
+  正常完成、typed host result 持久化后中断、原 journal 恢复及 committed 重放。
+  每个夹具最终仅一次宿主调用／attempt、一次 writeback 和一次扣额，重放不重复
+  效果。独立 argv 验收器接受字节相同的产物。每个版本使用隔离 native broker，
+  已核验停止与 OS 退出。这仍是确定性 transport 证据，不是模型宿主 V4 或正常
+  hard-lease V2 的资格。
+- **观察成本：** 每个版本一次正常插桩调用记录耗时 2.962 → 3.169 秒，父进程
+  CPU 0.737 → 0.775 秒、峰值 RSS 65.6 → 64.6 MiB；输出均为 3,474 字节。
+  已 wait 子进程的 CPU 为 0.567 → 0.599 秒。缓存、执行顺序与竞争工作未受控，
+  这些观察不证明延迟改善，也不建立回归阈值。broker RSS 观察及 wait 子进程的
+  usage 不覆盖完整进程树峰值、完整 wire／context 字节或模型成本。加载变化较小，
+  长程收益和 D6 资格仍未证明。
+- **`bc59a9ed4` 的历史验证限制：** 更广的源码选择为 596 个通过、一个 preview 冷 import 测试失败；
+  基线独立出现同一失败，原因是 `host_bridge_transport` 提前导入
+  `extensions.process_runtime`。owner 范围的 mypy 使用 `--follow-imports=skip`，
+  两个版本在线号归一化后均报告相同 29 个诊断，不代表完整配置的 mypy 套件。
+  两项失败均不豁免、不改写为通过。下述 process helper 接缝在同一作者提案中
+  修复 preview 失败，并保留类型检查限制。
+- **剩余：** 采纳仍受独立评审、必需验证和精确 head 的 merge readiness 治理。
+  opt-in minimal 选择、D2/D5 决策、完整 R0/V10/R1、hard-lease／上下文／模型
+  一致性和拆包安装仍未关闭；独立 status 提案 #8011 保留原限制。不改变权限、
+  provider、默认值、已安装宿主或发布行为。
+
+### 2026-11-06 — Preview process helper 保留在执行路径
+
+后续 runtime 提案 `a44e27d96` 修复未改动的 preview import oracle。先延迟
+bridge helper 暴露了 `doctor_git` 的第二条 eager import；两个 adapter 现均在
+执行／清理或显式 import 时解析既有 `process_runtime` owner。命名／star import、
+原函数身份、静态 alias、`dir()` 和公开 patch 点均保留。TypeScript Host lifetime
+及进程／权限判定不迁移。
+
+- **可观察结果：** 导入 preview command 加载 337 个 LoopX 模块，`bc59a9ed4`
+  为 338，仅移出 `extensions.process_runtime`。真实 Git 成功读取同样不加载清理
+  helper。实际 generic-cli 执行仍需要这些 helper，两个版本均加载 533 个模块。
+  本片修复加载边界，不证明提速或长程收益。
+- **真实路径：** 同一个隔离 SQLite harness 在两个不可变 runtime 版本通过正常
+  完成、typed result 后中断、原 journal 恢复及 committed 重放。产物字节相同，
+  每个夹具仅一次宿主调用／attempt、writeback 和扣额，重放无重复效果。两个自有
+  broker 均停止并核验 OS 退出。真实 bridge send／cancel、背压、deadline 和清理
+  未确认分支保留行为；真实 Git 超时／终端取消退役查询自有 helper。清理错误通过
+  既有 patch 点保留 unknown 诊断。
+- **限制：** macOS 跳过七个 Windows Job Object 用例。一轮组合验证因 Git 夹具
+  hook 未在既有预算内启动而失败；随后隔离 Git 选择通过，未修改预算或 oracle。
+  owner 范围的 mypy 检查三个受影响加载 adapter，基线与提案仍有相同 29 个诊断。
+  完整配置 mypy、打包／拆包安装、minimal 选择、D2/D5、完整 R0/R1/V10、
+  hard-lease／上下文／模型一致性及完整成本收益仍未取得资格。采纳仍受独立精确
+  head 评审与必需验证治理；前述历史失败仍是历史失败。
+
+### 2026-11-06 — 成对成本实验仍未取得资格
+
+`a9485073f` 对比 `86d9c542d` 的有界实验产生了有用的负面证据，未证明可归因的
+提速。实验在冻结的 20 分钟采样墙钟上限结束，共有 499 个通过语义断言的观察：
+八个源码组各完成 30 对；wheel 的 JSON version 完成九对，另有一个未配对的候选
+观察，其余 wheel 组未采样。原标准和全部观察均保留；上限触发及未完成组不改写为
+资格通过。随后集成的目标 `cd677182c` 不在这组不可变版本的测量中。
+
+环境为 macOS arm64、CPython 3.13.5、Node 26.0.0，真实 backend 是 Node owner
+的 SQLite 3.53.1。源码和隔离的单体 `loopx` 2.2.0 wheel 环境具有相同的 57 个
+依赖版本，并核验实际 import 来源。公开入口依次运行 JSON version、所选
+`performance-diagnosis` help、status、quota admission 和确定性 generic-cli
+任务，复用既有 `_write_live_fixture(provider="sqlite")` owner。顺序冻结为源码
+先于 wheel、上述命令顺序、冷路径先于暖路径，每对交替基线／候选顺序。每个任务
+使用新的合成状态。冷路径为新 Python 进程加已退役的自有 broker；暖路径为新
+Python 进程加保留的 broker。文件系统缓存未受控、禁止写入字节码，不声明冷磁盘。
+
+**缓存限制：** 既有字节码未归一化。后续盘点发现源码组 LoopX `.pyc` 数为
+7 对 1,241，依赖 `.pyc` 数为 2 对 344。两个版本的 JSON version 均加载
+1,157 个 LoopX 模块，父进程 read-open census 为 2,402 对 1,253。因此不能把
+源码观察到的下降归因于五个模块的加载变化；下表仅描述这些缓存条件。
+
+| 源码操作 | Broker 条件 | 基线秒数，中位数 / p95 | 候选秒数，中位数 / p95 |

+- **覆盖的成本：** 冷任务 target 和已 wait 后代的 CPU 中位数／p95 为
+  1.769 / 1.832 对 1.283 / 1.388 秒，其最大 RSS 为 79.2 / 87.4 对
+  75.5 / 78.7 MiB。独立 broker CPU 为 0.720 / 0.780 对 0.735 / 0.800 秒，
+  结束时 RSS 为 126.6 / 129.7 对 128.3 / 133.5 MiB；不代表并发进程树峰值或

+  宿主一分钟 load 范围为 5.00–14.42；这是具名环境的观察。
+- **独立 instrumentation：** 源码和 wheel 的任务加载仍为 538 → 533。
+  冷任务父进程 read/write-open 为源码 2,179/284 → 1,643/284、wheel
+  2,184/284 → 2,173/284。四个 capture 各有 238 次本地 IPC 连接；覆盖的 socket
+  send/receive 字节为源码 895,335/391,794 与 895,339/391,794，两个 wheel 均为
+  894,790/391,543，仅覆盖已观察的 Python socket，不覆盖全部 context、transport
+  或后代 I/O。独立源码冷任务 audit 的父进程／已 wait 子进程 CPU 为
+  1.234/0.560 → 0.802/0.582 秒，最大 RSS 为 88.7/75.3 → 63.4/75.4 MiB；

+
+采样前冻结代码/resource/wheel hash、工作负载、缓存、instrumentation、串行对照
+顺序、采样和解释规则。每次 CLI 都是新 Python、独立空 bytecode cache prefix，
+并禁止写入 bytecode。每个 episode 在 prequota 启动独立冷 Node，之后仅在同一轮

+已完成背景 Todo。大状态失败保留为失败，不算成功成本样本。
+
+全部 60 个计划观测在 **1,164.996 秒**内完成，未改变上限：52 个小状态 episode

+RSS 是各次 CLI 调用峰值的最大值，不是同时存活进程树的总峰值。Broker counter
+不含退出阶段，使用校准后的 Darwin timebase。默认 SQLite 的 target/waited CPU
+下降约 13–14%；broker CPU/RSS 没有一致改善。Source/SQLite prequota median

+Wheel/SQLite prequota 为 3.463 → 1.581 秒，guard 为 1.844 → 2.033 秒。
+降耗主要集中在新 Python 的 prequota loading，不能归因为 authority 执行加速。
+
+各组 setup median 为 2.15–2.29 秒，retirement 为 0.36–0.40 秒。包含 setup、
+退出和 driver 开销后，source/SQLite median 为 20.238 → 18.146 秒，wheel/SQLite
+为 20.393 → 19.793 秒。两个 wheel 独立构建/安装用时 43.881 秒。准备、验证、恢复
+与 census 有重叠，不能相加。准备阶段作者成本、完整 native/thread/进程树 I/O、
+model token、model/人工成本及长程结果仍未完整测量。内核观察到的 broker 磁盘写入
+保持约每轮 SQLite 5.85 MiB、File 220 KiB；这不是全部文件系统流量。
+
+60 个观测的产物字节、原绑定、完整结算义务、一次 writeback 和一次 debit 一致。
+小状态必读 native initial body 为 23,498–24,442 bytes；`bytes / 4` 仅是粗 token
+proxy，不是 tokenizer 结果或 model retention 证明。候选多出的 source 85 / wheel
+165 bytes 来自路径/reference 展示；规范化后的结算义务逐条一致，没有删减。
+
+101 个 Todo 时，普通 completion 会把原展示位置靠前的选中 Todo 和 90 个背景
+Todo 自动归档。Validation、writeback、一次 spend 已提交，后续原 Turn 的
+`todo complete --no-follow-up` 却因 `todo_archived` 拒绝。四组 source/wheel ×
+File/SQLite 对照在两臂均复现。失败轮没有计入验收成功，也不用于宣称完整大状态
+加速。既有 `todo_terminal_lifecycle.ts`、`todo_archive_selection.ts` owner 需要协调
+自动归档和原 receipt 的终结。相关 #5677 已负责 freshness/terminal recovery；其
+公开的 0/1/4 history 矩阵没有验证本次自动归档分支。扩展既有 owner 时，保留 fresh
+archived-Todo、变更 actor/lease/evidence 和重复 effect 的拒绝。
+
+独立 census 在八个 source/wheel × File/SQLite 变体中保留 invalid Vision/workspace
+拒绝。每个变体另有四个失败检查：missing Node admission、missing provider、capture
+digest 不匹配，以及 released-claim completion；没有提交 writeback/debit。
+Prequota 的 soft failure 继续进入 quota，不授予 admission。负例检查用时 69.559 秒，
+instrumented census 用时 90.358 秒，两阶段有重叠。采样/census 的所有 broker 都已
+观察到 shutdown 与 OS exit；pilot 初次 wrong-source retirement/pending wait 的失败
+保留在历史中，随后在其独立 namespace 完成退出回读。
+
+剔除 census 额外两个拒绝后，各变体完整 episode 的 RPC 均为 271 → 270，spend
+单独为 83 → 82。实际 receive 流量为 999,060–1,004,527 → 966,984–972,825 bytes；
+send 为 1,025,077–1,037,023 → 1,026,956–1,040,098 bytes，增加来自候选更长的路径。
+Parent read-open 为 13,532–13,561 → 11,700–11,728，write-open 为 285 → 284。
+带 instrumentation 的 prequota module graph 为 source 1,404 → 480、wheel
+1,403 → 479，包含 instrumentation 自身 import，不是未插桩的 loading 预算。
+Census 的冷 Node/readiness 为 0.217–0.249 秒，version probe 为 0.026–0.032 秒。
+单次插桩用时不能证明重复延时收益；socket/open 计数也未覆盖全部 native/broker I/O。
+
+**基于证据的下一步：**把归档分支交给既有 terminal/freshness owner 和 #5677
+集成验证，再验证完整大状态生命周期。保留原 operation/read/receipt identity 与
+所有拒绝边界；不为让这个工作负载通过而修改归档策略。随后 characterize 剩余
+`quota should-run` parser/loading 与共享 projection caller，再选择性能改动。
+小状态数据支持继续对 #8240/#8243 的精确 head 做 review，不授予 merge 或已安装
+host 采纳资格。I3 至少保留一个 minor release；M1/#8011、完整 R0/V10/R1、
+D2/D5/D6/D3、context/model/split-install、真实 adoption 和完整成本验收仍开放。
+没有新增 budget、preset、provider 或 authority。
+
+Source 重放时，拉取两个精确 PR head，仅将生产 `loopx/` 差分应用到隔离的
+baseline archive；记录的 merge base 分别为
+`79665b97a0a453380da02e15b1b62eee895147df`、
+`97cc1e0c40e766c73193b8077526a7f565dc561b`。使用 `uv sync --extra test` 准备
+console，并用 `uv build --wheel` 分别构建单体 wheel；构建前通过既有 owner 验证
+Chat bundle。复用 `tests/control_plane/test_quota_settlement_cli.py` 的 source fixture：
+在 `_initialize_fixture_authority` 前完整编写 synthetic Goal/背景 Todo，选择 File
+或 SQLite 与 `hard_lease`，通过普通 claim 准备执行。Todo 和 Goal boundary 同时
+声明产物 write scope，复用 Git fixture helper 并创建独立 worktree。
+
+以下重放序列的每条命令都必须指定该 fixture 的 registry/runtime/worktree；guard
+提供完整 read/recovery 命令。保持同一 Goal、Agent、Todo、Turn 和 claim operation：
+
+```text

+```
+
+Admission/writeback/spend 声明该 fixture 已观察到的 shell、filesystem-write、network
+和 evidence-poll capability；生成的 reader 命令使用实际安装的 console。用不变参数
+重放 completion、writeback、spend、terminal。Missing Node 使用隔离 PATH，missing
+provider 使用空的 disposable runtime，stale source 使用不匹配的 capture digest，
+stale claim 使用普通 release 后的 lease。它们必须在 writeback/debit 前拒绝；invalid
+Vision/workspace 同样保留拒绝。临时测量 harness 和 raw capture 保持私有；这个 recipe
+描述重复的 workload/oracle，不是分发的 benchmark runner 或公共复现 receipt。
+
+### 2026-11-07 — 原 Turn 终结在 Todo 自动归档后仍可完成
+
+#8257 的完整 CLI 比较在 101 个合成 Todo 下暴露了生命周期故障。基于
+`4a33eb4b5` 的新源码 console 复现在 File 和默认 SQLite 上均保留同一
+`todo_archived`：普通完成、持久写回和一次额度扣账已提交。冻结比较保持原样，
+这些失败 episode 不计入验收通过的延迟样本。
+
+修复提案仍由 `todo_terminal_lifecycle.ts` 拥有。在仅限 active 的拒绝之前，
+复用已有同 Turn fence 与精确普通 completion receipt 校验，验证已归档 Todo
+的终结资格。一个文件内 helper 统一 active 和已归档路径的父 receipt 检查。
+原 claim/lease、任务 digest、validation 声明与 receipt、provider CAS 校验
+继续生效；归档选择与保留阈值保持原样。允许的只是原 completion 的终结阶段，
+不会重新开放已归档工作。
+
+真实 File/SQLite console fixture 现在可以完成大状态整轮，并回放 completion、
+写回、扣账和 terminal closeout：只有一次扣账，独立验证的 JSON 结果保持原样。
+持久 CLI 回归使用真实 validator 和普通 hard-lease claim，拒绝过早结算、
+无关归档工作、其他 actor、claim 或 Turn，以及变更后的 completion intent。
+终结保留原已通过的 validation receipt、首次完成时间和归档状态，不重复执行
+validator。既有 provider conformance 继续检查 source/digest、validation、
+lease 和 replay；隔离真实 PostgreSQL suite 单独验证其共享 owner。
+
+作者提案还集成了 main `abf144202`（#8161）：显式 Goal 范围的检查不约束局部
+Todo 完成。归档回归在局部 validator 之外加入未通过的整体 Goal 承诺检查：
+普通完成和终结仍保留原 receipt 与一次扣账，不重复执行 Goal checker，整体
+检查继续失败。这是作者阶段的集成覆盖，不能替代独立审阅或审阅修复后的
+wheel 资格验证。
+
+#8264 `12627eff8` 的独立审阅发现：只改 `--evidence` 就能替换已归档 Todo
+接受的产物，却仍返回旧 validation receipt。File/SQLite × 有无整体 Goal 检查
+的四个 fixture 均在该 head 复现失败。修订集成 target main `10f66ec5e`，在归档
+终结前拒绝不同的显式 evidence；新归档 closeout receipt 同时保存已接受证据，
+让变更后的重试不能通过 receipt recovery 绕过检查。带有效 completion note 时，
+省略或空 evidence 保留原值；CLI 原有的完成说明要求继续适用。
+历史 fingerprint 和旧 receipt 继续兼容，active completion 行为保持原样。
+回归在 terminal replay 前后检查 canonical evidence、原 validation 和完成时间，
+以及只执行一次的 validation/writeback/debit。此前被审阅的 head 仍未获验收。
+修订 `7ec8d19b9` 已获得独立
+[APPROVE 审阅](https://github.com/loopx-project/loopx/pull/8264#pullrequestreview-5811807012)，
+#8264 已以 `172d80d63` 合入。
+
+基于 target main `32167518b` 的验证现在覆盖源码 console 和新构建、隔离安装的
+单体 wheel。构建 wheel 前，已通过既有 owner 构建并验证 Chat bundle。
+File/SQLite × source/wheel 四组 episode 均包含 101 个合成 Todo，使用真实
+console、普通 hard-lease claim，以及独立验证的 JSON 产物。在一次扣账提交后，
+fixture 只停止自己的 Effect 进程；新的 console 进程通过重启后的 runtime
+恢复原 terminal 结果。Canonical 回读保留已接受证据、首次完成时间和归档状态。
+Completion、写回、扣账和 terminal 重试仍保留四步已提交 receipt 和一次扣账；
+terminal commit 前和 replay 时都拒绝替换证据。最后一次原 Turn guard 不再声明
+可执行工作或执行义务。Wheel 的 console/import provenance 与源码 fixture
+准备环境分开核对。

+### 2026-11-07 — Guard 加载与已结算回放诊断
+
+`6c10e61ad` 的源码 console 诊断复用上述真实 101-Todo hard-lease episode，
+隔离 File/SQLite authority 与自有 Effect 进程。新增五个 episode 均在受控重启
+后保留已验收证据、首次完成时间、四份已提交 receipt 和一次 debit；证据替换与
+已结算 Turn 的再次执行仍被拒绝。只对 guard 和不可变上下文读取做剖析。这些
+包含 profiler 开销的单次诊断观测，不是配对性能运行。
+
+| 字节码条件 / provider | 插桩 guard | import 累计 | 跟踪的 runtime 请求 | 请求耗时之和 | 已加载 LoopX 模块 |
+| --- | ---: | ---: | ---: | ---: | ---: |
+| 禁用字节码 / SQLite | 3.012 秒 | 2.281 秒 | 89 | 0.370 秒 | 503 |
+| 禁用字节码 / File | 1.972 秒 | 1.255 秒 | 89 | 0.344 秒 | 503 |
+| 正常继承字节码 / SQLite | 1.584 秒 | 0.845 秒 | 89 | 0.394 秒 | 503 |
+| 正常继承字节码 / File | 1.465 秒 | 0.772 秒 | 89 | 0.342 秒 | 503 |
+
+禁用字节码时，SQLite / File 的源码编译分别占 0.634 / 0.555 秒；两次正常
+字节码观测均未调用源码编译。import、loader 读取与编译时间相互嵌套，不能
+相加。字节码条件解释了部分启动成本，加载图仍相同；这不能修正或覆盖冻结
+比较的失败。第五个正常字节码 SQLite episode 中，guard 加载 503 个模块并
+跟踪到 89 次请求，不可变上下文 reader 加载 68 个模块并跟踪到一次请求：插桩
+耗时分别为 2.140 / 0.246 秒，请求耗时之和分别为 0.389 / 0.067 秒。这是在
+刻画不同的必要操作，不代表两条路径可以互换。
+
+runtime 请求耗时包含 Python transport、共享 runtime 与 provider 工作。它只
+是这些已跟踪请求中 provider 贡献的上界，不是单独的数据库计时或完整 service
+CPU。四次 guard 观测的 source snapshot 约为 0.048–0.050 秒。因此下一步
+成本调查优先考察 decision/status 加载图，而不是新 provider 或 fingerprint
+优化。仅移动 `quota_context` import 无法省去后续 status collector 仍需要的
+工作；quota 已省略 presentation projections，不可变上下文 reader 也已有
+选择性加载路径。
+
+真实 File/SQLite Monitor episode 还验证了独立 sibling 到期时，已结算与
+关闭后回放仍保留原身份。每个原 Turn 保留一次 poll、零 debit，不调度 sibling。
+通过公开 `configure-goal --quota-compute 0` 入口，暂停仍优先并返回
+`quota_skip`。初始 probe 修改的是旧 `status` 字段，未修改 typed activation
+或 quota owner；暂停预期失败属于夹具错误，与修正后的检查分开保留。
+
+| Provider / 回放阶段 | 插桩回放 | import 累计 | 跟踪的 runtime 请求 | 请求耗时之和 | 已加载 LoopX 模块 |
+| --- | ---: | ---: | ---: | ---: | ---: |
+| SQLite / 已结算 | 1.135 秒 | 0.666 秒 | 68 | 0.150 秒 | 486 |
+| SQLite / 已关闭 | 1.149 秒 | 0.726 秒 | 62 | 0.157 秒 | 486 |
+| File / 已结算 | 1.113 秒 | 0.713 秒 | 68 | 0.143 秒 | 486 |
+| File / 已关闭 | 1.128 秒 | 0.691 秒 | 62 | 0.149 秒 | 486 |
+
+下一步仍在既有 quota/status 与 typed replay owner 内推进：先确定每类 decision
+实际需要的 live facts 和 import，再保持公开 facade 等价性，去除无用加载或
+重复共享请求。仅凭 receipt 提前返回尚未取得资格：当前暂停、scoped gates、
+独立 pending intents、actor/lease/source 检查，以及归档或关闭后的 lineage
+必须保留。实现后仍需相同的真实 source/wheel 生命周期，以及不插桩、匹配条件
+的默认 SQLite 比较；影响到其他受支持后端时，其正确性、恢复与必需的真实
+PostgreSQL 资格继续适用。本诊断没有修改生产行为、preset、budget、provider、
+authority 或 installed host。既有验收、采纳和完整成本缺口继续开放。
+
+### 2026-11-07 — Guard 成本候选取舍与 context transport 组合
+
+隔离的源码 console 反事实在函数被调用时才加载三个 Monitor adapter 依赖。
+101-Todo SQLite 生命周期仍保留原 artifact、首次完成时间、四份 receipt 与
+一次 debit。guard 从 503 个模块降至 502 个，跟踪的 runtime 调用仍为 89；
+只有 `todos.external_wait_contract` 消失。Monitor 历史查找与 quota accounting
+admission 在 guard 路径实际执行，其依赖仍然必要。因此不选择这项 import
+延迟作为下一成本缩减切片；临时 wrapper 不是生产实现或兼容性资格。
+
+既有 context transport 候选与加载缩减分别验证：
+[#8286](https://github.com/loopx-project/loopx/pull/8286) 的 `efce6cb9c` 跳过
+inactive Anti-Entropy validation；
+[#8290](https://github.com/loopx-project/loopx/pull/8290) 的 `9537687be` 从
+status-only context validation 中省略 governing source。以 runtime base
+`32167518b` 为基线的临时组合 overlay，已跑四组 File/SQLite × base/overlay
+完整源码 console episode，每组含 101 Todos。已验收证据、首次完成时间、
+受控 Effect 重启、四份已提交 receipt 和一次 debit 均保留；证据替换与已结算
+Turn 的再次执行仍被拒绝。组合源码另通过 91 个聚焦 Python 用例与 20 个
+TypeScript 用例，零 skip。验证后恢复临时变更的路径，没有新增竞争实现或合入。
+
+| Provider | guard 跟踪调用，base → overlay | JSON 参数字节，base → overlay | 加载模块，base → overlay |
+| --- | ---: | ---: | ---: |
+| SQLite | 89 → 87 | 1,904,862 → 1,772,448（−6.95%） | 503 → 503 |
+| File | 89 → 87 | 1,903,569 → 1,771,587（−6.93%） | 503 → 503 |
+
+这些单次插桩观测统计传入共享 runtime 的 UTF-8 JSON 参数，不含 transport
+header、retry、response、startup 或 service CPU；不是完整 wire 字节或延迟
+比较。SQLite base 的两个 status-only validation 输入共 134,868 字节，
+overlay 唯一保留的输入为 2,045 字节。不可变 context 与 settlement owner
+继续负责原边界。这独立验证了有界 transport delta，但不证明候选 merge、组合
+wheel、installed-host adoption 或完整任务收益。冻结成本研究没有变更。
+
+剩余最大的 guard 参数生产者是 `todo.context.page`（九次调用共 789,198
+字节）、`todo.quota_planning.project`（390,361 字节）和
+`goal.vision_wait.project`（185,559 字节）；SQLite base 与 overlay 数值
+相同。下一有界调查先在这些既有 typed projection owner 中验证 canonical
+Todo source 的复用，再实现一个完整 source-read transaction。必须保留
+source/provider revision、actor/lease fence、完整 exact read、archive/replay
+lineage、pause/gates 与 pending intents。新增更多 leaf RPC 或有损裁剪 source
+字段不能取得 transaction cutover 资格。#8123 的既有 Goal-route 工作与其未
+解决的性能 hold 保持独立。新实现仍需完整 source/wheel 正确性，以及不插桩、
+匹配条件的默认 SQLite 全路径比较；既有里程碑、采纳与完整成本缺口继续开放。

+It records a bounded target and acceptance-source reference, an outcome

+A changed decision must cite the current same-Todo finding; validation and append
+CAS use the same graph snapshot. An exact durable replay with an original commit
+strictly older than the current choice may restore its missing historical
+capture. This does not relax predecessor checks for equal-time or newer work,
+and attachment callers cannot supply the replay timestamp. Current context
+selects by original committed time, so late ingestion cannot replace a newer
+choice. Ordinary work preserves its original settlement type and never creates
+an obligation to satisfy Stride v2. Replans retain their existing v2 contract.
+An absent attachment preserves the current decision; an explicit `proxy: null`
+chooses direct evaluation while historical profiles remain readable.

+`execution_profile.yardstick_enabled` is an independent, default-off setting of
+the existing Goal review/stride capability. Machine and Goal editors share that
+owner; an explicit Goal false wins. Explore evidence must be available before a

+capability. Disabling removes the extra ordinary-Turn cue and rejects new
+captures before primary commit, while historical findings and successful exact
+replays remain readable.

+The existing Research finding reader exposes the recorded target, outcome/proxy
+metrics, source, next action and cost bound. The ordinary task-scoped Explore
+context projects only that Todo's current target, a short next-choice cue and
+counterevidence references. Its existing question-scoped read command exposes
+the full decision, exact-profile feedback and prior execution attribution; the
+default projection does not repeat that full record.
+Counterevidence requests reassessment at the next concrete choice; it is not a
+new hard gate, fidelity certification, permission to waive correctness or an
+instruction to replan every Turn. At a later meaningful capture, existing
+execution observations can bind the predecessor's proposed method to the actual
+method, candidate and evidence, including a justified different method.
+
+Source validation includes a real isolated SQLite CLI → ordinary guard →
+concrete synthetic artifact/evaluation → same-Todo result journey, off-mode
+rejection/readback and recovery checks. Its deterministic actor demonstrates
+transport and attribution only. The packaged configuration journey qualifies
+machine inheritance, Goal overrides and failed-read recovery; the populated
+Research reader qualifies the original HTTP/SQLite history on desktop and narrow
+screens. Lark uses its existing finding-summary projection, with no external send

+marginal cost and matched benefit remain untested; schema survival and synthetic
+followthrough do not close C13 or M2/M3.

+
+[OpenAI documents native Goal](https://developers.openai.com/cookbook/examples/codex/using_goals_in_codex)
+as durable state within a thread, with completion, budget and continuation
+controls. LoopX adds a project work record of accepted requirements, Todos,

+In Codex CLI, it still uses native `/goal` to drive continuation, as described
+in step 2. You can start with one Agent; adding another host or Agent requires
+its own setup. Check whether the retained work actually informs later actions.
+
+Choose a real job where you need to inspect that continuity:
+
+| Job | A concrete change during the work | What to inspect before accepting it |
+| --- | --- | --- |
+| Keep finding and fixing bugs in one module | You add a compatibility constraint after several repairs | The existing LoopX Goal retains the new constraint, earlier valid requirements and evidence; the next repair follows them |
+| Work through a PR review queue | A PR changes its head, or one merge needs your decision | Findings identify the reviewed revision; that decision holds the affected merge while independent authorized reviews can continue |
+| Supervise a longer research effort | An experiment fails or new evidence challenges the current approach | Failed and uncertain results remain available; the Agent explains why it changes or continues the approach, and records the resulting outcome and cost |
+
+For the recurring job in step 5, try a natural follow-up in the **same Goal**:
+
+```text
+For future repairs, leave each patch uncommitted until I review it.
+Keep the other accepted requirements and existing results. Before continuing,
+show where this correction is retained and which next action changes.
+```
+
+Inspect the retained work and the next actual patch. An acknowledgement or a

+A registered pack can include an authored reading companion through
+`trajectory-pack-register --case-study-json case-study.json`. This is an optional
+benchmark-toolkit presentation, qualified by its TypeScript owner. It requires
+no model receipt. Goals with a companion open a case reading view; the existing
+research records and analysis remain accessible. Without one, the existing
+reader is unchanged. The CLI registration is the authoring entrypoint; the
+workbench selects, reads and traces the saved result without model execution.
+For benchmark research, each case is an ordinary child Goal of the benchmark
+Goal using the existing `parent_goal_id`. Register that case's evidence packs
+under its child Goal, not under a parent-level case selector. The parent links
+to child research spaces; each child links back and retains its own records,
+findings, documents and reading versions. Parentage neither merges evidence
+nor grants execution. Navigation stays within the same status source.
+
+The document has `title`, `language` (`zh` or `en`), `summary`, summary
+`citations`, `sections` and `limitations`. Each section has a unique `id`,
+`title`, Markdown `text` and `citations`, and can combine a table
+(`columns`, `rows`), categorical numeric series (`label`, `unit`, `points`
+of `{label, value}` with null for missing measurements), or a timeline
+of `{label, title, text}` entries. Authors choose the order and composition.
+Reading should explain conclusions, unfamiliar domain concepts, competing
+approaches, decisive observations and remaining uncertainty. It does not require
+exercises, actions or note-taking. Charts preserve gaps and show exact values;
+they do not infer interpolation, ranking or comparability.
+
+Citations use the pack's absolute source-line ranges. Registration verifies the
+artifact bytes and qualifies every range, but does not establish entailment or
+scientific validity. The companion becomes part of pack identity; editing it
+requires a new registration and preserves the prior version. It does not change
+the model prompt, analysis key or scoring owner. Source changes preserve the
+registered reading and cited snapshot with a historical warning. Language
+switches show the saved original with a notice, without inventing a translation.
+Rendering uses the existing Markdown renderer and host-owned components, with
+no executable HTML. Porthole is not a runtime dependency of this reader.
+
+Documents are bounded to 160,000 serialized characters and 24 sections, with
+smaller per-block limits. This bounds the existing full-pack HTTP read and DOM
+render without truncating conclusions or evidence. Larger studies should split
+into separate source-scoped packs; rejected documents are not silently shortened.
+Select **Research records and analysis** to return to the original reader;
+this view choice is retained in the URL. Registering a pack without a companion
+does not delete an existing study, historical source or saved result.

 `runtime-observation`. Apply its typed terminal or runner-invalid transition before
 releasing that reservation, then backfill the reported gap.
 
+Managed providers can deliver a completed closeout through one host operation:
+
+```bash
+loopx benchmark terminal-reconcile \
+  --goal-id <registered-goal-id> \
+  --request-json managed-terminal.json \
+  --execute --format json
+```
+
+Without `--execute` this previews the transition. The request contains the
+original executed, newly-created `admission_receipt` (not an idempotent
+admission lookup), the existing board `identity`
+(`benchmark_id`, `study_id`, `case_id`, `run_id`, `arm_id`, `arm_role`, `attempt`),
+and the provider's `terminal` proof: the same identity, terminal `status`,
+`observed_at`, and explicit `solver_terminal=true` and `grading_drained=true`.
+This is trusted controller input, not solver input. The provider must qualify
+runtime continuity against its retained launch and native event evidence before
+publishing it. A running solver, pending
+grading, an unknown observation, missing board/ledger, mismatched admission, or
+a conflicting terminal status is rejected without releasing a reservation.
+The managed path requires a unique run ID across the Goal's board; it rejects
+the same reservation appearing in multiple studies rather than guessing its owner.
+Every launch or replacement must use a fresh Goal-wide run ID. Deliberately
+reusing both an old run ID and its admission timestamp is outside this managed
+contract; the legacy reservation format cannot distinguish that duplicate tuple.
+Forward the original whole provider proof. Do not assemble its admission and
+terminal pieces from separate runs. The shared CLI validates its bound state
+transition; it does not independently reread provider files or attest the SDK.
+
+The TypeScript policy checks the exact admission generation (`admitted_at` as
+well as run/case/role). The existing local ledger transports lock the concurrency
+envelope and board in that order, recheck the policy's input snapshot, write and
+read back the terminal row, then release and read back that original slot.
+An intervening write requires retrying the original proof; it does not authorize
+a replacement admission. A process interruption after the board write can be
+replayed. Same-terminal replay preserves later scores, insight and observation
+time, and an already released run is idempotent. This is process-crash recovery,
+not a new power-loss durability guarantee. New state transitions use the actual
+host reconciliation time, strictly after the current board observation and no
+earlier than provider termination; replay keeps the persisted timestamp. A stale
+running shard can therefore be merged again without an equal-time ambiguity.
+
+This command never stops workers, deletes artifacts, restarts an experiment,
+changes duration allowances or upgrades score qualification. Keep accepted
+grading alive until it drains. The provider/controller owns bounded retry after
+an unavailable writer; no scheduler or polling loop is installed. A terminal
+board row alone is not a release receipt. Read `board_readback_verified` and
+`slot_readback_verified`; new admission still needs its own resource checks.
+Standalone board upserts and explicit `concurrency-release` retain their
+existing behavior. The managed command additionally requires a registered Goal
+and cannot use an unregistered project override.
+
 For hosts where parallel jobs can exhaust temporary storage, memory, process
 capacity, file descriptors, persistent storage, or provider capacity, enable
 `--require-resource-headroom-receipt`. Each new admission must then include a

Let Explore Graph activation remain inside the goal-aware material refresh path; keep generic Kanban user-command-only unless a separate goal opt-in projects one concise executable post-writeback action through quota/status.

Keep the candidate and result attestations explicit. Verify canonical graph readback and replay on the same Turn. |
 | `explore_graph_delivery_postcondition_gap` | Graph-on is enabled and local projection changes, but the agent delivers before the configured board is synced, or a sink failure is only a warning and the remote board silently stays stale. | goal `explore_graph` policy, material refresh packet, sink semantic/readback digests, row/result ids, current external-write authority, final delivery timing. | Feature activation scheduled best-effort projection but did not expose or enforce a material-delivery postcondition; the agent also treated graph sync as a deferrable P1. | Require configured sink sync plus row/result-id readback after material refresh. Authorized failure blocks delivery and remains retryable; suppressed external delivery preserves local state but requires a concrete successor.

+"""One owner decides the reviewer-notification queue receipt schema version.

+``issue_fix_reviewer_notification_queue_receipt_v1`` names one wire contract, and
+two modules stated it: ``loopx/domain_packs/issue_fix.py``, which the capability
+surface already imports for the local-time shape, and
+``loopx/capabilities/issue_fix/reviewer_notification.py``, which restated it under
+an ``ISSUE_FIX_`` prefix. A version bump in one file would have left the other
+accepting the previous contract, which is the failure the local-time owner test
+was written to prevent.

+Layer 1 judges folded values rather than spellings, so a copy written across
+lines, built with ``+``, declared with a type annotation, or interpolated from
+same-file constants into an f-string is reported too.
+Layer 2 pins the consuming module to the owner's object and checks that it keeps
+no local binding. Layer 3 records that the current and legacy receipts stay
+distinct at the boundary that reads a queued receipt.

+"""Guard one owner for the material-lifecycle apply outcome vocabulary.
+
+`build_material_rerank_apply_receipt` records the result of one apply and
+`build_material_ranked_entry_rebuild_apply_receipt` replays a whole plan. Both
+ask the same question -- is this token a legal apply outcome -- and on the base
+revision each stated the answer with its own module-level set, so a status added
+on one side stayed illegal on the other while every scan that groups by name
+still saw two matching definitions.
+
+Decisions are made on the folded value, not the spelling: a plain set literal, a
+reordered literal, a `set(...)` or `frozenset(...)` wrapper, and a one-step
+comprehension over the same members are all offenders. Constructions whose
+members cannot be folded statically are not reported; widening the census to
+them means teaching `_folded_members` to decide them and adding a case here,
+rather than declaring a site and trusting it.
