Full details: Cmux Algorithmic ComplexityExplanation The new runtime path hashes the app-host product tree with an unbounded global sort. In Resolution Replace the global materialization and sort with a linear-time canonical traversal or another deterministic hashing design. If the sort is required, document an explicit product-tree size bound and add a benchmark or profiling measurement for the expected 1000+ file tree, including the twice-per-run pre/post validation cost. Full details: Description checkExplanation The description gives a detailed summary, rationale, implementation scope, validation details, and related issues. However, it omits the required Testing, Demo Video, Review Trigger, and Checklist sections from the repository template. Resolution Add the required template sections. Include exact test commands and manual verification under Testing, provide a demo video or explain why it is not applicable, include the review-trigger comment block, and complete the Checklist with the current review and testing status. ✨ Finishing Touches 💡 1📝 Generate docstrings 💡

In `@docs/workload-profiles.md`:
- Line 101: Update the cold-state rule in the workload profile documentation:
explain that omitting --state-root for a cold state class creates a temporary
root, while an explicitly provided root must already be empty; retain that warm
classes require an explicit state root.
In `@scripts/ci/cmux_workload_profile.py`:
- Around line 703-747: Update the semantic-result condition and cleanup metadata
in the result-building flow to use settled_cleanly: remove the cleanup_state ==
"incomplete" check from the ambiguous-result condition and set
process_group_settled directly from settled_cleanly. Preserve the existing
result and comparison behavior for forced cleanup.
- Around line 790-794: Delete the unused validate_result_document function and
leave load_result using validate_result_structure with its stricter repository,
profile, type, and metadata checks unchanged.
In `@scripts/ci/workloads/macos-app-host-test-shard.sh`:
- Line 67: Update run_batch to explicitly capture and validate the shard planner
command’s status, returning its nonzero status immediately on failure instead of
relying on set -e. Then explicitly reject an empty only_testing_args array by
reporting the error and returning nonzero, preventing xcodebuild from running
without shard filters.

Reconvened on current head The earlier draft dependency on teamleaderleo/glaeda#1088 no longer applies to this PR's merge boundary: Also confirmed the fresh Greptile dev-build finding is repaired on this head: Moved the PR back to ready-for-review. Completed checks on this head are green; the main CI run is still executing. #1088 remains the activation prerequisite for candidate-eligible physical fleet receipts, not for landing the CMUX profile core. |

In `@scripts/ci/cmux_workload_profile.py`:
- Around line 946-963: Update the timeout and settlement flow around
child.wait() and settle_process_group() so the child remains waitable until
settlement, using waitid(..., WNOWAIT) rather than reaping it before the probe.
Extend process_group_alive to ignore the known zombie leader and assess only
remaining group members, then reap the child with child.wait() after settlement
while preserving existing timeout exit-code behavior.

raises “semantic result toolchain identity is inconsistent” after the preceding
observation checks. Leave the existing observation validation and other
toolchain validation unchanged.

Current head closes the remaining actionable review items: workload children now stay unreaped through process-group settlement via waitid(..., WNOWAIT), residual group probing ignores the known exited leader before a one-shot SIGKILL/ambiguous fallback, and the child is reaped only after settlement; duplicate toolchain identity validation is removed; dev-check validates the sanitized tag-slug bundle path; focused tests cover unreaped wait identity, leader exclusion, and the tagged bundle path. The previously flagged platform-mock, shard-planner fail-closed, cold-state docs, and legacy validator items were already fixed. Auto-merge remains enabled; fresh CI is running on the current head. |

Verification receipt for the workload-profile repair pass: current head
The branch includes the settlement metadata fix, explicit shard-planner failure handling, result-comparison identity recomputation, untracked-source refusal, and self-contained product-tree symlink checks from this review pass. |

CMUX repeatedly asks CI, developer machines, and fleet workers to perform the same meaningful operations, but those operations currently have no stable repository-owned identity. That makes machine acceptance, cache experiments, Glaeda routing, and performance comparisons vulnerable to command drift.
This adds a first-generation workload registry and semantic runner owned by CMUX.
Result
The first four profiles are:
cmux.macos.compile-admission@1cmux.macos.dev-check@1cmux.macos.app-host-test-shard@1cmux.ci.guard@1Each profile binds an explicit semantic generation, repository entrypoint, platform requirements, result/artifact class, timeout/resource/network class, and admitted benchmark-state classes. Internal refactors can preserve a generation when the operation and validity contract stay equivalent; semantic changes require a generation bump.
The runner freezes the exact CMUX commit/tree, validates profile generation and bounded parameters, invokes only checked-in CMUX entrypoints, records stage timings/toolchain/resources/artifact identities/process settlement, and emits
cmux-workload-result/v1withpassed|failed|timed_out|ambiguous.Benchmark comparison keys bind exact source tree, profile/generation, semantic validator, reviewed environment class, semantic parameters, exact runtime-input identities, state class, and toolchain.
comparerefuses mismatched semantics/context, failed results, incomplete artifact validation, or incomplete cleanup.The existing
workflow-guard-testsjob now runscmux.ci.guard@1through this runner and prints the semantic receipt, giving the first hosted execution path.Existing front doors

Summary by cubic
