Pi Posthorse synthesis verification

Type: agentic-system-analyses/types/agentic-system-verification.md

Verification

The handed synthesis supports publication as a bounded implementation account. I checked its substantive statements against the supplied runtime, memory, epistemic and workflow members, the reconciliation, and the two settled verification judgments. No synthesis refusal was supplied and synthesis answers are empty. Reconciliation declares neither supersessions nor unresolved conflicts. This judgment checks meaning and qualifications, not deterministic reference or quotation occurrence.

Boundary, ownership and admission

The public opening identifies the frozen extension revision, cutoff and evidence layers. It distinguishes included SDK callers and evaluator source from observed execution, and external Pi responsibilities from Posthorse controls. These distinctions agree with the boundary and Source register. The account does not imply host qualification or measured task success.

The preparation and reset passages preserve model authorship, code admission and host commitment as separate stages. Request-local guidance, forced-prompt delivery, reminder eligibility and model compliance are distinguished. The reset callback's recorded identity and size admission do not become a commitment guarantee; foreground errors, abort checks, pending input and later-handler exceptions remain beside the claim. Publication is not semantic approval, and rejected reset admission does not undo successful sibling effects. The cited RT-RTE-request-guidance, RT-RTE-explicit-reset, RT-RTE-note-admission and MEM-OBJ-notes support these statements. Model version and deployment uncertainty remain faithful to RT-CMP-active-model.

Recovery and read-back

The automatic-recovery account retains the conditions that bound no-summary construction: a reached supported custom hook, a narrower eligible threshold fallback, and manual/unsupported native alternatives. Cancellation is scoped to the supported handler rather than asserted as a transaction over journal mutation or all host activity. Later projection edits and competing handlers remain consequential exceptions. See RT-RTE-automatic-recovery.

Provenance classification is not strengthened into authentication of truth or present authorization. The public text preserves effective tool registration, unnamespaced projected linkage and successful result requirements for owner answers. Its receipt account allows errors and orphan/legacy asynchronous evidence without inferring completed work. The ancestry, nonautomatic-checkpoint and truncation passages agree with EPI-RTE-recovery-provenance, EPI-OBJ-result-evidence, MEM-OBJ-recovery-record and EPI-RTE-recovery-reshape. Deterministic construction is not equated with semantic equivalence or exclusion of all model-authored interpretation.

Automatic checkpoint delivery is separated from requested notes/history recall. The selectors, original/replacement distinction, project/subagent scope, estimated shared page budget and display-only expansion claims are supported by MEM-RTE-notes-recall, MEM-RTE-history-recall, RT-CMP-page-reservations and MEM-OBJ-posthorse-display. Archive access is not recast as agent launching, delegate initialization or a completion barrier.

Workflow and independent property assessments

The selected workflow remains one connected scripted fixture, with a separate rejection/retry scenario. Its terminal answer and reopening assertions are evaluator design, not task-state acceptance or observed recovery. The workflow account and EPI-RTE-reset-evaluator support that characterization.

The scenario-relative conclusion distinguishes implemented continuation channels from completeness, synchronization and live-state correctness. Capacity arithmetic remains conditional on host estimates. The positive trace-learning finding is narrowly an automatic trace-fed retained update with a later model channel at wired strength; it does not assert improved capacity, parameter learning or an outcome comparison. Its support remains MEM-OBJ-recovery-record, EPI-RTE-recovery-reshape and MEM-BAP-recalled-content.

Theory-builder conditions, criticism-induced capacity improvement, reflection, autonomous theory building and self-improvement are left independently unestablished rather than bundled into an absence claim about the host model. The accepted records do not supply a formulated-theory criticism/iteration chain or an objective-bearing improvement update with subsequent causally dependent operation. Fixed guidance and continuation wiring are not substitutes. See RT-RTE-request-guidance, RT-RTE-automatic-recovery and the epistemic bounded conclusion. The proposed evidence that could change these assessments is conditional, not claimed evidence or an adoption recommendation.

Carriage of settled limits

The public Limitations carries both report-verification limits with their record citations, inspected scope and prevented comparisons: recall equivalence/exact replay and selected evaluator coverage/general reliability. Profile verification declares no additional limits. The remaining rows faithfully retain external ownership, local hook guarantees, unresolved initial/native provenance, semantic truncation, missing operation and causal evidence, and unestablished improvement properties. They do not excuse unsupported emitted values or contradict the bounded account.

No additional record fault or material unsupported conclusion was found. Source-read log: none; no ambiguity required frozen-source inspection beyond the handed records.

Blockers

none

Limits

• MEM-RTE-history-recall and RT-RTE-retained-retrieval: retained inspection of SRC-1, src/session-files.ts, src/history-search.ts and src/history-entries.ts supports scoped requested recall and paging but does not certify full-scan equivalence across arbitrary encodings and queries or exact normalized replay. Withhold exhaustive-recall and exact-replay comparisons. The synthesis Limitations already states this carried limit and its resolving evidence.
• EPI-RTE-reset-evaluator and the workflow account: SRC-1, test/official.test.mjs supplies selected reset/read/reopen and rejection/retry evaluator designs, not an exhaustive assertion audit, passing execution or live task-state verification. Withhold total evaluator-coverage, checker-correctness and general recovery-reliability comparisons. The synthesis Limitations already preserves this carried limit; the selected connected workflow remains supported.
