PR
#7868requires the moved UI rules to preserve behavior. The current PR description reports a behavior change: unusual HTTP(S) links are nowBlockedinstead ofWeb. This conflicts with the issue acceptance criterion that the moved rules' behavior remain unchanged. The host import switch, manifest changes, boundary exception removal, v0.18.6 repin, and reported lockfile updates address the other listed objectives. The available evidence does not show that the moved rule tests passed.Resolution

Tiny Sweeper reviewNo actionable findings were raised across the five review lanes (critique, security, tests, commits, description). The change replaces the direct `tinymcp` dependency on the hosts and core crates with the `tinymcp-bus` contract crate, repins the TinyMCP module record to release v0.18.6 with contract version (1, 25), and removes the now-unneeded `hosts:tinymcp` module-boundary exception. The tests lane judged the swap mechanically sound with no new untested behavior, and the description lane confirmed the pull-request body accurately describes the diff. Reviewers noted the vendored `tinymcp-bus` sources and the v0.18.6 digest values could not be independently verified in this deployment because the submodule is not checked out, but the updated registry test asserts the new version, URL, and sha256 values. State: Incomplete Review snapshot
Completeness: Incomplete What changedAll review lanes found 0 active findings. The critique, security, and commits lanes reviewed with nothing sensitive or problematic found; the commits lane specifically reported nothing sensitive in the committed content. The tests lane concluded that the change moves the hosts and core off the `tinymcp` implementation crate onto the `tinymcp-bus` contract (same `ui` functions re-referenced by path), removes the now-unneeded `hosts`/`tinymcp` boundary exception, and pins the module to 0.18.6 with contract (1, 25), with the registry manifest test updated in this diff to assert the new version, URL, and every sha256 so the pin is covered; every swapped call site is a compile-checked path change with identical semantics, the core `ui` re-exports are exercised by the existing `cache_tests`/`decorate_tests`/`discovery_tests`/`ops_tests` files, and no new behavior is introduced that lacks a failing test. The description lane verified the body matches the diff, including the fail-closed link-classification behavior change, while noting the vendored `tinymcp` submodule is not readable in this deployment so the v0.18.6 digest values themselves are unverifiable here though they are asserted in the updated registry test. Multiple lanes noted the code index is behind this pull request (indexed at `b728b0815680`), so retrieved context may be out of date. Features

…ct tinymcp dep tinymcp moved its pure tool-UI rules into the contract (tinymcp_bus::ui, tinymcp#105), so openhuman-core and openhuman-app no longer need to link the tinymcp module crate for them. Switch every tinymcp::ui import, and tinymcp::MCP_RESULT_KIND, to tinymcp_bus; drop the direct tinymcp dependency from both hosts (the app takes tinymcp-bus instead); and remove the temporary hosts:tinymcp module-boundaries exception.
v0.18.6 ships tinymcp#105 (tool-UI rules in tinymcp-bus, contract 1.25), which the host switch in the previous commit needs. vendor/tinymcp moves to the v0.18.6 tag (3c3967fce). The registry record's version, release_url and all 17 archive sha256 come verbatim from the release's checksum.toml via release-and-repin.mjs, as does the published-manifest test. The lockfiles drop tinymcp from the hosts (and, in the app, the now-unused tinymcp package with its dirs 7 dependency) and take tinymcp-bus 0.18.6 with base64.

tinysweeper could not review the latest push, so its earlier approval no longer speaks for this pull request.
