Hosts need shared hosting vocabulary and an owning-module directory preparation operation before they can stop linking provider and bundle implementations. This PR adds pure tinyhosts-bus DTOs, errors, schemas and tool declarations, with library compatibility re-exports, plus authorized bounded preparation through the existing Execute(String) envelope. Providers() and all existing arities, operation/result tags and ten model tool declarations remain unchanged.

A trusted host authorizes a canonical workspace and relative source before calling preparation. The module walks anchored directory handles without following symlinks, excludes credential stores/environment/build files, and returns the actual standard-base64 snapshot plus facts. Approval and deployment use those exact bytes; the compiled fixture changes the source after preparation and verifies the original bytes are uploaded. Supplied Launch/Deploy bundles also reject credential paths. Windows absolute/NUL paths and FIFO replacement have regression coverage.

Preparation is bounded by 4 MiB decoded source, 4,096 files, 16,384 examined entries, 64 directory levels, 1,024-byte relative paths and 6 MiB conservative JSON output charged before base64 allocation. These limits apply to preparation. Existing larger supplied Launch/Deploy requests retain the transport budget; a regression and compiled artifact probe upload 6 MiB raw/8 MiB base64 successfully. Larger directory snapshots and streaming remain required followup capabilities for full host integration.

Validation: 210 all-feature and 179 default tests including doctests pass; strict clippy, all-target build, rustdoc and format pass. All 19 implementation source files exceed 90% coverage (minimum 91.23%, preparation 94.02%). Default/all-feature normal/build contract closures contain only serialization/error derives. Actual cdylib loader exercises Providers, existing requests, preparation snapshot binding and large legacy deployment against local provider mocks. Independent scoped review accepted the preparation and the legacy-budget followup after fresh regressions/artifact probes.

Host ModuleClient integration, authorization/model-dispatch restrictions, root gitlinks and artifact pins remain separate, gated on a published compatible module artifact and verified digest. No package version or release is manually changed. Granular commits and existing PR history are preserved.

Part of tinyhumansai/openhuman#7292.

📝 Walkthrough
📝 Walkthrough

Walkthrough

The pull request adds tinyhosts-bus as a workspace crate for shared hosting types and RPC contracts. The module uses those contracts and adds bounded bundle preparation from authorized directories. CI, coverage, release workflows, tests, and documentation now account for the workspace and the new behavior.

Changes

Shared hosting contract and bundle preparation

Layer / File(s) Summary
Shared hosting vocabulary and compatibility exports
Cargo.toml, crates/tinyhosts-bus/Cargo.toml, crates/tinyhosts-bus/src/error/mod.rs, crates/tinyhosts-bus/src/inputs.rs, crates/tinyhosts-bus/src/launch.rs, crates/tinyhosts-bus/src/model.rs, src/error/mod.rs, src/host/types.rs, src/launch/types.rs, crates/tinyhosts-bus/README.md, docs/specs/minimal-bus-contract.md, AGENTS.md
Adds shared errors, request inputs, launch results, and provider-independent hosting types. Existing modules re-export the shared types. The contract documentation describes interfaces, serialization, and responsibility boundaries.
RPC envelopes and module integration
crates/tinyhosts-bus/src/lib.rs, crates/tinyhosts-bus/src/rpc.rs, crates/tinyhosts-bus/src/lib_tests.rs, src/rpc/mod.rs, src/rpc/mod_tests.rs, src/tinybus_module/*, src/tools/mod_tests.rs, src/lib.rs
Adds shared RPC request and result envelopes, provider and tool declarations, and contract-version constants. The module adopts the shared envelopes and constants, clamps site and deployment list limits to 1–100, and returns Unsupported for unmatched operations.
Authorized bundle preparation
crates/tinyhosts-bus/src/preparation.rs, src/preparation/*, src/rpc/mod.rs, src/rpc/mod_tests.rs, src/bundle/*, src/lib.rs, examples/verify_module.rs, README.md
Adds authorized-directory and prepared-bundle types, bounded filesystem collection, and bundle-path checks. PrepareBundle returns a prepared snapshot without provider or credential lookups. Tests and the verification example cover snapshot behavior, exclusions, limits, symlinks, and legacy bundle sizes.
Workspace workflows and project guidance
.github/workflows/ci.yml, .github/workflows/release.yml, .github/scripts/check-file-coverage.sh, tests/release_workflow.rs, AGENTS.md
Runs CI, coverage, and release checks across the workspace. Release version discovery selects the tinyhosts package, and version updates include the tinyhosts-bus manifest. Tests cover package selection and version updates.

Merge Risk: ⚪ Minimal · up to 0e02d

The version-bump concern is addressed, and no actionable merge-blocking risk remains from the supplied evidence.

Security Architecture Review

Security architecture risk: 🟡 Moderate · up to 0e02d

The new operation can return local source files. Strong path, credential-exclusion and resource limits reduce risk, but safe exposure depends on trusted callers and workspace authorization that are not demonstrated here. No unauthorized production access has been established.

Retained concerns

  • Medium · security · inferred: The new local-file RPC relies on caller isolation and workspace authorization outside the module. AuthorizedDirectory is a deserializable scope declaration, not authorization proof, and Execute forwards preparation without a caller-policy check. If an untrusted caller can reach this interface, it could request nonexcluded files from caller-selected canonical directories readable by the process. Documentation prohibits that exposure, but the production enforcement boundary is unresolved.
Security review details

Security Blast Radius

  • inferred — Conditional on untrusted Execute reachability, exposure extends to nonexcluded regular files readable by the hosting process beneath caller-selected canonical workspaces, rather than a module-owned workspace allowlist. Per-call collection limits do not establish tenant isolation. Production caller access and filesystem privilege scope remain unknown.

Security Findings and Attack Paths

  • inferred — The unresolved attack path is an untrusted caller supplying a directory scope through Execute and receiving encoded source files without a caller-policy decision in this module. Explicit trusted-host requirements and the prohibition on generic model forwarding are counterevidence. This is a conditional architecture concern, not a verified unauthorized-access finding.

Trust Boundaries and Controls

  • observed — The host owns authorization, system-root restrictions and deployment approval; the module owns input validation and collection. PreparedBundle carries files and counts, not an authorization token or deployment-target binding. Approval must therefore retain the returned value and submit those exact bytes through a trusted caller.

Resilience and Maintainability Implications

  • observed — Preparation bounds decoded bytes, files, examined entries, depth, relative path length and serialized output, charging encoded growth before allocation. No-follow and nonblocking opens reject symlink and nonregular replacement hazards. Collection does not version-check concurrent regular-file writes or promise a transactionally consistent directory image; the demonstrated guarantee concerns bytes retained after return.

Hardening Proposals

  • proposed — Before exposing preparation through a production host, demonstrate authenticated, restricted Execute access and identity-scoped workspace policy, including denial of generic model forwarding. Keep the approved bundle immutable and associated with the intended deployment so approval cannot accidentally authorize substituted bytes.

I’m a rabbit with a bundle to pack,
I gather safe files and leave secrets back.
A snapshot holds each byte in place,
While limits guide my digging pace.

And workspace checks keep builds in song.

Review comments at @.github/workflows/release.yml:
- Line 143: Update the version-bump step to also change the root Cargo.toml
dependency requirement for tinyhosts-bus to match the new version before cargo
update runs, while preserving the existing package-version updates.

Review comments at @Cargo.toml:
- Around line 35-36: Remove the redundant version requirement from the root
tinyhosts-bus path dependency so release version bumps do not make Cargo reject
the local crate.

equality assertion against an empty `Vec<BundleFile>` to avoid the
`assert_is_empty` Clippy lint while preserving the empty-bundle check.

Review comments at @src/preparation/mod.rs:

use a lowercase form of the name, matching the existing case-insensitive
credential checks. Ensure collect also skips mixed-case names such as
.Env.local.
