Verification

The handed public synthesis supports a bounded source-grounded account. No material blocker or additional unresolved defect was found. Its central distinction holds: retained context, admitted effects and evaluation-responsive change are implemented capacities; semantic accuracy, successful delivery and improved future capacity are not established by that wiring.

I read the full supplied invocation, governing types and contracts, boundary, four analyst reports, reconciliation, synthesis and both preceding verification judgments. The synthesis answers file is empty, and no refusal or previous synthesis verification was supplied. I assessed every substantive synthesis passage, its supporting records, the reconciliation's four supersessions and each Limitations row. No source files were read, no target was executed and no evidence or analyst record was added. This is a support judgment, not a repetition of deterministic form checks.

Runtime and representative delivery

The evidence basis, enclosing-runtime classification, frozen revision, cutoff and external exclusions agree with boundary and evidence. The public text explicitly distinguishes a whole-system source boundary from exhaustive route inspection. It does not attribute external service inference or persistence internals to the shipped client.

The request-to-effect account is supported by RT-RTE-foreground-turn, RT-OBJ-tool-context and RT-CMP-turn-model. The synthesis keeps model proposal separate from host continuation and permission admission. Its distinction between consent and truth, and between shell isolation and arbitrary executable extensions, preserves the scope of RT-CLM-approval-policy, EPI-RTE-hook-policy and RT-CLM-shell-isolation.

The listener's unknown-before-effect and exact-after-settlement account preserves the conditional protocol of RT-RTE-listener-approval and RT-CLM-effect-checkpoint. It promises neither exactly-once effects nor rollback and does not extend the listener callbacks to ordinary headless execution. Alternate ingress and scheduled work are supported by the runtime account and RT-RTE-scheduled-prompt; queued work is not presented as completed work.

The delegation account remains conditional on a local non-memory Task and a live bidirectional session, as established by RT-RTE-subagent-task and the workflow account. Launch receipt, child protocol settlement, product verification and parent delivery remain distinct. Bounded notifications and the one-time truncated-stream retry are not converted into full-report delivery, generic correctness verification or effect rollback. Task's unrestricted child default is expressly not generalized to every delegation route.

Retention, transformation and authority

The public memory account preserves committed automatic projection versus working-tree tool reads, metadata discovery versus full skill injection, and automatic history versus requested search. These distinctions are supported by MEM-RTE-core-projection, MEM-CLM-visibility-boundary, MEM-RTE-deferred-read, MEM-RTE-skill-loading and MEM-RTE-transcript-search. It does not imply semantic relevance ranking or that all memory consumers require commitment.

Structural admission, factual acceptance and model-interpreted authority remain separate. The false-body counterexample is supported by EPI-RTE-frontmatter-check; the hook and restore qualifications follow EPI-RTE-commit-admission and EPI-RTE-memory-restore. The archive mismatch follows MEM-CLM-archive-projection. None becomes a claim that all memory adoption lacks semantic checking.

Compaction and reflection remain distinct trace-fed chains. MEM-RTE-transcript-compaction supports bounded summary generation and summary-plus-tail retention, not fidelity. MEM-RTE-reflection-integration supports proposal integration, retries, successful no-change consumption and later file consumers. Requested contradiction correction and skill generalization remain doctrine-strength under EPI-RTE-reflection-guidance. The reasons requested in reports and commits are not claimed to reach normal body-only consumers. Arena choice, attachment withdrawal and opaque hosted alternatives retain the qualifications of MEM-RTE-arena-selection, MEM-RTE-repository-sync and MEM-OBJ-hosted-memory.

The synthesis uses the memory-side canonical summary/projection/fetch/arena identities while retaining the epistemic generation, retention and semantic assessments. The reconciliation supersessions therefore do not strengthen evidence or erase distinct functions. No unresolved analyst conflict was declared in the supplied reconciliation.

Independent properties and carried limits

The assessment leads with the strongest supported improvement-directed contribution: scenario evaluation, prior-attempt feedback, pass-responsive selection and optional executable copying in EPI-RTE-mod-evaluation and EPI-RTE-mod-selection. It keeps subsequent live loading separate under RT-RTE-extension-load. Settings and release changes are not mistaken for evidence-responsive improvement.

The theory-builder discussion separately identifies missing formulation, content-dependent decisions, content-directed criticism and criticism-shaped iteration. It treats them as unestablished, not absent. Learning from criticism, requested self-representation, maintenance without per-edit human approval and dormant self-improvement are separately qualified, consistent with the epistemic bounded conclusion. Lack of supplied runs is not used to erase inspectable capacities, and source wiring is not used to close an exercised or beneficial improvement chain. The proposed evidence that would change these assessments addresses activation, subsequent causal dependence and benefit separately.

I checked all eleven Limitations rows. They preserve the consequences and record citations of both report-verification limits: the omitted Workflow delegation route prevents cross-route generalization of Task grants and recovery; the incompletely characterized initialization/reorganization procedure prevents a complete content-checking inventory or an inference that all memory adoption lacks semantic checks. The preceding profile verification declares no additional limit. Other rows retain the source reports' external, provenance, replay/selection, repair, arena, enforcement and evaluation uncertainties without implying absence or complete coverage.

Read without supporting-member context, the synthesis defines its operational distinctions and keeps consequential conditions beside its claims. Its scenario-relative capacities and proposed resolving evidence do not introduce a product ranking, transfer recommendation or system-wide epistemic grade. The existing limitations preserve the supported public account; no new limit needs to be carried into it.
