Outcome: changes-requested

Policy assessment
@foo-bender, AgentLine has a substantive agent-native telephony identity: agents receive persistent numbers and use documented REST, MCP, skill, SDK, webhook, and relay surfaces for calls, inbound SMS, transcripts, and events. Identity & Comms fits, the five submitted evidence items are structurally valid and supported, and no duplicate listing was found.

The profile nevertheless contains stale factual statements. limitationsMd says current first-party sources disagree about one-time versus monthly number fees, US versus Canada availability, and outbound SMS; the current homepage, introduction, and pricing page now consistently state $2/month US numbers and inbound SMS only. unknownsMd says the homepage Python install command conflicts with the SDK documentation, but both now use agentline-ai; Node is explicitly documented as not yet on npm. Please update or remove those obsolete conflict statements and refresh their evidence dates as appropriate.

This PR also has maintainerCanModify: false. If the corrected entry passes, enable maintainer edits so the required focused reviewer-owned SEO/provenance commit can be applied. SEO metadata was not evaluated in this failing review.

Evidence checked
Validated https://docs.agentline.cloud/introduction, https://docs.agentline.cloud/guides/calls, https://agentline.cloud/skill.md, https://agentline.cloud/pricing, and https://github.com/AgentLineHQ/AgentLine, plus the current homepage and MIT licence.

Checks run
Against current main 66026dc9943c8c8c4b2fa344e033206116b90c11: npm run validate:content passed; npm test passed (84/84). These schema results do not resolve the stale profile claims above.

Applied the requested corrections in e1ad84c: updated the listing to the current $2/month US-only numbers, inbound-only SMS, agentline-ai Python package, and Node-via-REST status; removed the stale source-conflict claims; refreshed evidence dates; and retained only unverified hands-on service quality as an unknown. Local tests pass (84/84), content validation passes, and both GitHub checks are green. GitHub will not enable maintainerCanModify because this is a same-repository PR rather than a fork PR; maintainers already have direct access to the branch. Ready for the policy/SEO re-review.
