Summary

This PR closes the last missing production component in the ACMS context assembly pipeline by implementing DepthReductionCompressor for the skeleton-compression stage.

The change:

• adds a production DepthReductionCompressor that re-renders inherited parent fragments to overview depths 0-1
• resolves reduced detail levels through the UKO DetailLevelMap inheritance chain for code, language-specialized, document, data, infrastructure, and generic fragments
• exports the compressor through cleveragents.application.services and makes ContextAssemblyPipeline default to it instead of the no-op skeleton compressor
• adds BDD coverage for compressor behavior and for default pipeline wiring
• updates CHANGELOG.md with the user-facing change entry required by the contribution guidelines

Motivation

Issue #919 identifies the skeleton-compression stage as the only remaining ACMS pipeline component that still lacked a production implementation. The repository already referenced builtin:DepthReductionCompressor in configuration, but no matching implementation existed. This PR brings the runtime behavior in line with the specification and closes that pipeline gap.

Validation

Completed locally:

• nox -e lint
• nox -e typecheck
• nox -e unit_tests
• nox -e integration_tests
• nox -e coverage_report (97.47%)

Environment note:

• nox -e e2e_tests is blocked locally because the real-provider E2E acceptance suites require external LLM credentials in this environment. The code changes for #919 do not touch those flows.

Closes #919

Review: APPROVED with Comments

Strong feature implementation with good BDD coverage.

Notes

1. acms_skeleton_compressor.py at 579 lines slightly exceeds the 500-line guideline. The 5 render visitor classes could be extracted to a separate module.
2. Breaking metadata type change: DepthBreadthProjector metadata values changed from int/bool to str. The step assertion was loosened to match. This could break downstream consumers — ensure nothing depends on the numeric types.
3. Mixed concerns: The metadata type changes and import refactoring in depth_breadth_projection.py are separate from the compressor feature. Ideally separate commits.
4. builtin: import path: getattr(builtin_services, class_name) without validation could import any public name. Consider an explicit allowlist.

## Review: APPROVED with Comments Strong feature implementation with good BDD coverage. ### Notes 1. **`acms_skeleton_compressor.py` at 579 lines** slightly exceeds the 500-line guideline. The 5 render visitor classes could be extracted to a separate module. 2. **Breaking metadata type change**: `DepthBreadthProjector` metadata values changed from `int`/`bool` to `str`.

This could break downstream consumers — ensure nothing depends on the numeric types. 3. **Mixed concerns**: The metadata type changes and import refactoring in `depth_breadth_projection.py` are separate from the compressor feature.

@freemo addressed the review notes and force-pushed feat/depth-reduction-compressor on top of the latest master.

Updates from your comments:

• extracted the skeleton render visitors into src/cleveragents/application/services/acms_skeleton_renderers.py so acms_skeleton_compressor.py stays under the size guideline
• restored DepthBreadthProjector projected metadata values to native int/bool types so downstream consumers do not see the string coercion change
• kept the depth_breadth_projection.py changes scoped to the compressor integration and child-focus prioritization, without the earlier metadata/import refactor drift
• added an explicit builtin allowlist in ComponentResolver and covered the rejection path with the new features/component_resolver.feature scenario for builtin:ConfigService

auto/last-attempt-tier-min

In-cycle escalation: most recent attempt ran at the Tier -1 slot (`tier-min`). Slot's model defined in .opencode/models/tiers.yaml. Suffix is ``-min`` (not ``--1``) so the Forgejo UI reads naturally.

Train repeatedly lost master-tempo races. Driver excludes via merge_cycle until cooldown elapses; label persists as visible history.

  

auto/revert

Revert PR backing out an invariant violation. Fast-tracked through the merge driver.

  

auto/sentinel

Sentinel PR duplicated from upstream into a personal fork by tools/duplicate_prs_to_fork.py for pipeline testing. Lives only in the fork; the canonical pipeline never sees it.

No implementer activity for N days. Flagged for human review. Auto-cleared on next push to head branch.
