What & why

Loop actions can now return payloads larger than the task-run envelope without losing coordinator restart safety or bypassing bounded tool results. Values up to 16 KiB remain inline; larger values are stored in the existing loop blob store and exposed through an exact-byte, workspace-authorized paging resource. Values above the effective action budget fail with the typed action_result_too_large error before task completion.

This also hard-cuts spec-cycle task fan-out from embedded bodies to path plus body_ref, adds bounded result disclosure to the task UI, and pages compozy__tool_list so the global tool-result limit remains enforceable.

How you verified it

  • make gate: codegen, Go lint, Go race tests, SDK Go, SDK TypeScript, and web all pass for fingerprint 3712e97b36f4a6ec6b148516c9beabf7d34dfe4f.
  • Isolated runtime QA reassembled a 71,694-byte result byte-for-byte through CLI, HTTP, native tool, web copy, and daemon restart; a 307,200-byte result failed with action_result_too_large and released its lease.
  • ET-035 walked all 275 native tools across three bounded pages and verified typed errors for invalid paging bounds.
  • Scenarios LP-oversized-action-result-fails, TA-task-run-result-paging, TA-web-task-result-disclosure, LP-spec-cycle-path-fanout, and ET-035 pass.
  • Both strict QA audits report PASS with zero blockers and zero warnings; both isolated labs tore down with clean: true.
  • Codex implemented this change; the result was reviewed against the accepted plan, deslop guidance, targeted suites, public-surface QA, and the scoped local gate.

Impact

  • CLI/API/web: adds compozy task run result, HTTP/UDS task-run result paging, Host API tasks/runs/result, native compozy__task_run_result, and bounded web disclosure/copy.
  • Docs: updates task-run, loop, tool, extension, configuration, CLI, example, glossary, and official Compozy skill references.
  • Config: no new or deprecated config.toml keys; the existing tool-result budget remains the source of truth.
  • Native tools: adds the result tool and descriptor/toolset/schema coverage; compozy__tool_list now returns deterministic pages while compozy__tool_info retains full descriptors.
  • Extensibility and hooks: Host API and spec-cycle contracts are updated; no hook, capability, bridge SDK, MCP-sidecar, or extension-resource lifecycle changes.
  • Workspace data isolation: results remain task/run/cell scoped; HTTP, UDS, Host API, native tool, cache keys, and store reads propagate workspace identity and mask foreign resources.
  • Official Compozy skill: task orchestration, loops, native tools, tool catalog, extension authoring, and configuration references are updated.

  • make gate passes locally; this PR is delivered only after its required CI checks are green
  • New or changed behavior is covered by tests, or I explained above why not
  • If an agent wrote or co-wrote this, I named it above and verified the result myself

Summary by CodeRabbit

  • New Features
    • Added paginated task-run result retrieval through the API, CLI, native tools, and Host API.
    • Added exact byte-range navigation, base64 transport, integrity checks, and access controls.
    • Added web UI support to view, navigate, retry, and copy large run results.
    • Added result references and byte counts to task-run details.
  • Bug Fixes
    • Enforced configurable result-size limits and clearer errors for oversized or invalid results.
    • Removed raw task bodies from imported task payloads while preserving body references.

Walkthrough

This change adds paginated task-run result reading across storage, APIs, CLI, native tools, Host API, SDK, and web UI. It also enforces action result-size limits, paginates native tool_list, and removes inline task bodies from the spec-cycle import payload.

Changes

Task results and result-size handling

Layer / File(s) Summary
Spec-cycle import payload cleanup
extensions/spec-cycle/*
The import-tasks output no longer includes inline body. Tests validate body_ref and the updated schema digest.
Task result state, paging, and persistence
internal/task/*, internal/store/globaldb/*
Runs now store inline or external result metadata. The task service and store read exact result pages and validate stored result data.
HTTP, Host API, and generated contracts
internal/api/..., internal/extension/..., internal/extensionprotocol/*, sdk/go/contracts/*
The API, Host API, permissions, routes, and SDK contracts expose task-run result pages.
CLI and native tool surfaces
internal/cli/*, internal/daemon/native_*, internal/tools/builtin/*, internal/toolmeta/*
The CLI adds task run result. Native tools add task_run_result and paginated tool_list behavior.
Loop action result size enforcement
internal/loop/*, internal/daemon/loop_*, internal/tools/result_limit.go
Loop actions use configurable result-size limits and reject oversized or truncated results.
Web task result fetching and display
web/src/systems/tasks/..., web/src/systems/os/apps/tasks/*
The web UI fetches, pages, copies, and renders external task-run results. Supporting settings and generated-contract updates are included.

Estimated code review effort: 5 (Critical) | ~110 minutes

Merge Risk: 🔵 Low · up to 24cc3

The PR enables large task results to be retrieved in pages and rejects oversized loop outputs before completion. Remaining merge-readiness risk is limited to UI structure/markup consistency and test assertion organization, with no demonstrated production correctness or security defect; it is mergeable with explicit owner awareness and follow-up.
