…ability feat(module): add bound ordinary stream callbacks
Add a test asserting that a stream aborted before its handle-carrying method is dispatched still surfaces StreamAborted to a late receiver instead of a missing handle, and correct the ignore reason on the host stream callback test to name the right environment variable. Auto-committed-on: dragonfly
The late-accept test now writes a chunk before aborting and asserts the reader still receives that buffered data before observing the terminal abort error, so the test reflects that a stream remains available as a terminal failure until it is accepted. Auto-committed-on: dragonfly
Abort now marks the stream finished and sealed while retaining an unclaimed reader, so a method carrying the StreamRef that is dispatched after Abort observes the terminal stream error instead of a missing handle. Ownership is checked against the sender and the retained entry is dropped once a reader has claimed it, bounding the state through the existing closed-unread cap and idle reaper. Auto-committed-on: dragonfly
Add a test asserting that an unclaimed aborted stream is evicted by the same bounded closed-unread policy as an unclaimed completed stream, so abort retention cannot grow without bound. Auto-committed-on: dragonfly
Update the locked versions of rustls-webpki to 0.103.16 and webpki-roots to 1.0.10, refreshing their checksums accordingly. Auto-committed-on: dragonfly
fix(stream): preserve aborted streams for late receivers
Adds a new test case to verify that an authenticated peer is only available after a module is live and ready. This ensures correct lifecycle management for module interactions. Auto-committed-on: dragonfly
This updates the host stop call within the host tests to use the inner field directly. This change aligns the test implementation with the current internal structure of the host. Auto-committed-on: dragonfly
Introduces `authenticated_peer` to return the broker-assigned unique peer name for a module only if it is live and ready. This ensures that peer names are only provided for modules that are fully operational and capable of serving requests. Auto-committed-on: dragonfly
The test for authenticated peer availability was updated to use the host's direct peer access instead of establishing a full connection and proxy. This change simplifies the test while still verifying the expected behavior regarding authenticated peers. Auto-committed-on: dragonfly
Adds a test case to verify that the authenticated peer for the Clock module is available after establishing a connection and proxy. This ensures the module can be correctly accessed via the bus. Auto-committed-on: dragonfly
Adds assertions to the host authentication test to verify that the authenticated peer matches the expected module and that the bus name is not registered as authenticated afterward. This ensures proper cleanup and state verification after a successful authentication flow. Auto-committed-on: dragonfly
This change updates the assertion in `authenticates_native_context` to clone the bus name when comparing the attestation result. This ensures correct ownership when asserting against the expected structure. Auto-committed-on: dragonfly
This change refactors the assertion in `host_tests.rs` to improve readability by breaking the assertion across multiple lines. This does not change the test's behavior. Auto-committed-on: dragonfly
This adds an assertion to ensure that the peer is not authenticated when the host is in a terminal state before detachment. This helps verify the state transition logic under specific conditions. Auto-committed-on: dragonfly
This adds a test case to verify that an authenticated peer becomes unavailable when the module's info is disabled and then unavailable again when the module is faulted. This ensures correct peer management during module state transitions. Auto-committed-on: dragonfly
Expose authenticated peers for loaded modules
Adds Connection::try_serve_at, which exports an interface at a path only when that interface name is not already served there, returning an error instead of replacing the live implementation. The check and insert happen under the object-tree write lock so concurrent registrations cannot both claim the same address. Auto-committed-on: dragonfly
Reformatted a multi-line error construction in the connection code and updated the connection tests to use a dedicated object path for the concurrent serve case and to compare against the expected JSON value. Auto-committed-on: dragonfly
Add a test asserting that serve_at still replaces an existing interface and routes calls to the replacement, guarding the behaviour alongside the new collision-refusing try_serve_at path. Auto-committed-on: dragonfly
try_serve_at previously rejected a registration only when an interface with the same name was already served at the path, so a second, differently named interface could be added alongside it. It now treats any occupied path as a collision and leaves every existing interface untouched, matching the documented contract. Auto-committed-on: dragonfly
Collapse the multi-line serve_at call in the try_serve_at test into a single line. No behaviour change. Auto-committed-on: dragonfly
Add non-replacing object registration for scoped endpoints

A rabbit checks the stream’s small flow,
Then watches callback bytes go.
A path stays put when claimed before,
An abort still leaves a reader more.
The fixture hops through tests with care,
While queued-up chunks remain to share.

- Around line 400-415: Expose the existing stream authorization predicate
through HostCallbackGuard by adding authorizes_stream, using
authorized_stream_module’s checks for non-confidential context, live binding
state, configured stream endpoints, and the exact authenticated sender. Update
the authorizes documentation to clarify it applies only to confidential members,
while leaving its behavior unchanged.
Review comments at @crates/tinybus/src/stream/mod.rs:
- Around line 491-497: Update the abort handling around the retained reader
check in the stream lifecycle so pending Write tasks are explicitly notified of
abort and their chunks.send awaits terminate, while still retaining the reader
for later dispatch to observe the terminal stream error. Preserve the existing
behavior for already-claimed readers and the closed-unread retention limits.

…horization Add a test asserting that aborting a stream wakes a chunk write blocked on a full window and still lets the reader drain the unclaimed chunk before seeing the abort. Also extend the host callback tests to check that the binding guard authorizes streams for the module peer only, and stops doing so once revoked. Auto-committed-on: cuttlefish Co-authored-by: Medulla <medulla@tinyhumans.ai>
Moved the stream authority check onto the shared callback state so the host callback guard can expose an authorizes_stream predicate alongside the existing confidential authorizes check. The binding now delegates to the same helper instead of duplicating the logic. Auto-committed-on: cuttlefish Co-authored-by: Medulla <medulla@tinyhumans.ai>
…orted A watch channel now signals abort to writers blocked on a full chunk window, so they fail with StreamAborted instead of hanging until their deadline. This preserves an unclaimed reader so it can still drain buffered chunks and observe the terminal outcome. Auto-committed-on: cuttlefish Co-authored-by: Medulla <medulla@tinyhumans.ai>
Reformatted two registry dispatch calls in the abort test to single lines, matching rustfmt output. No behaviour change. Auto-committed-on: cuttlefish Co-authored-by: Medulla <medulla@tinyhumans.ai>
The marked_bundle helper now restricts the artifact directory and its ancestors to mode 0700 so the fixture matches the permissions the download cache expects. Auto-committed-on: cuttlefish Co-authored-by: Medulla <medulla@tinyhumans.ai>
The artifact loading tests now create their temporary directories with tempfile::tempdir instead of nesting them inside the current directory, and on Unix a helper tightens the permissions of the created tree to 0o700. This keeps the fixtures out of the working tree and ensures the loader sees directories that are not group or world writable. Auto-committed-on: cuttlefish Co-authored-by: Medulla <medulla@tinyhumans.ai>
The lazy manifest test now builds its temporary directory inside the current working directory instead of the system temp location, so the test works in environments where the default temp path is not usable. Auto-committed-on: cuttlefish Co-authored-by: Medulla <medulla@tinyhumans.ai>
The lazy manifest test now builds its temporary directory inside the canonicalized system temp directory instead of the current working directory, avoiding failures when the working directory is not writable or is itself a symlink.

coderabbitai[bot]’s stale review
October 22, 2026 01:45
All actionable findings from this review were implemented and covered by regression tests; each review thread was replied to and resolved. I re-requested review twice on the updated head, but the latest CodeRabbit run is rate-limited. All required checks pass on dfb2f1c, so this retires only the stale verdict, not any unresolved feedback.

This brings the TinyBus API and stream changes from the OpenHuman storage-primitives epic onto canonical
main. OpenHuman's TSD #67 needsConnection::try_serve_atso host adapters can export an interface without replacing an existing object path. The fork's #16, #20, and #26 merge history is preserved; this branch also carries the authenticated-peer prerequisite from #24.Validation:
