Summary

Implements the LiveMaterializationStrategy — the third materialization strategy type defined in the specification's Output Rendering Framework. Updates RichMaterializer to use live rendering instead of sequential buffer delegation.

Changes

• src/cleveragents/cli/output/materializers.py: Added _LiveMaterializationStrategy class (~130 lines) with ~15fps throttling, dirty-element tracking, per-frame composition, and thread-safe operation. Updated RichMaterializer to extend it.
• features/output_rendering.feature: 5 new BDD scenarios for live strategy
• features/steps/output_rendering_steps.py: Step definitions
• vulture_whitelist.py: Added LiveMaterializationStrategy entry

Note

All 10 element types and handle classes were already fully implemented in prior work. The actual gap was only the LiveMaterializationStrategy.

Closes #903

Review: Looks Good (self-authored — posted as comment)

Well-designed concurrency model with proper frame coalescing. Thread-safe _lock protecting mutable state. _maybe_render_frame correctly uses time.monotonic() for frame timing. Deviation docs updated. Minor: add changelog entry and consider Robot integration test.

Updated Review (Deep Pass): Changes Required

My initial review looked good. The deep review reveals issues.

New Finding: Missing get_error_output() method — potential runtime error

_LiveMaterializationStrategy does NOT implement get_error_output(), but other strategies (_BaseBufferStrategy, _AccumulateStrategy) do. If get_error_output() is called on a RichMaterializer (which extends _LiveMaterializationStrategy), it will raise AttributeError. This is a potential runtime error in error paths.

New Finding: materializers.py pushed past 500 lines (now 677 lines)

This PR adds ~176 lines, pushing the file from ~501 to 677 lines — well over the 500-line limit. The _LiveMaterializationStrategy class (~170 lines) should be extracted to its own module.

New Finding: Dead field _ended

self._ended: bool = False is set on on_session_end() but never read anywhere. Either remove it or use it.

New Finding: import time as _time inside hot-path methods

Both _maybe_render_frame and _render_frame import time inside the method body. While Python caches module imports, this is unnecessary overhead on every call (~15 fps) and violates the import guidelines.

Previous finding still applies: Thread safety model is well-designed.

If `get_error_output()` is called on a `RichMaterializer` (which extends `_LiveMaterializationStrategy`), it will raise `AttributeError`.

Auto-agents controller manages this PR/issue (see tools/controller/deploy/RUNBOOK.md). Remove this label to abandon controller management.

  

auto/blocked-by-deps

PR blocked by an open issue dependency. Operator must close the dep (or remove the dependency link) before the merge driver can act. Auto-cleared by merge_drive when no open deps remain.

  

auto/ci-timeout

Most recent merge cycle hit CI timeout. Driver excludes this PR while last merge_cycle row is < 30 min old; label persists thereafter as visible history.

  

auto/claimed-implementer

auto/claimed-merge

auto/claimed-reviewer

Currently being processed by a reviewer worker.

  

auto/driver-down

Merge driver heartbeat stale; pipeline halted. Closed automatically on next clean tick.

  

auto/invariant-violation

Detected master commit violating the strict merge invariant. Tracked as an issue (not a PR label); kept here for label completeness.

  

auto/last-attempt-tier-0

In-cycle escalation: most recent attempt ran at the Tier 0 slot (`tier-0`). Slot's model defined in .opencode/models/tiers.yaml.

  

auto/last-attempt-tier-1

In-cycle escalation: most recent attempt ran at the Tier 1 slot (`tier-1`). Slot's model defined in .opencode/models/tiers.yaml.

  

auto/last-attempt-tier-2

In-cycle escalation: most recent attempt ran at the Tier 2 slot (`tier-2`). Slot's model defined in .opencode/models/tiers.yaml. Gated behind IMPLEMENTER_ESCALATION_TIER2_ENABLED.

  

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.

  

Automation Tracking

Tracking issues used by the AI Automation system for agents to communicate and report.

  

auto/needs-conflict-resolution

Rebase conflict needs LLM conflict-resolver.

  

auto/needs-implementer

Failing CI needs implementer attention.

  

auto/postmortem

Documenting a driver incident or rollback.

  

auto/ready-to-merge

Reviewer has APPROVED this PR and no later REQUEST_CHANGES is outstanding. The merge driver requires this label to even consider a PR for merging. Set by the reviewer worker on APPROVE; cleared on REQUEST_CHANGES.

  

auto/restart-throttled

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.

  

auto/stale-inactivity

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

  

auto/unstable

Repeatedly fails on current master (>= 3 ci-fail-on-rebased-sha releases in 12 h). Excluded from driver until human triage.

A ticket in a blocked state and unable to complete until some other task is completed first.
