Renamed the `template` and `template-bus` crates to `tinyruntime` and `tinyruntime-bus` respectively, along with all their internal paths and module names, to reflect the actual project identity rather than a placeholder name. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>
The greeting module and its tests were part of the initial template scaffolding and are no longer needed by the crate. Removing them eliminates dead code and keeps the source tree focused on the runtime's actual functionality. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>
The type parser now returns an error when given an empty string instead of panicking. This prevents a crash when malformed input is provided to the language module. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>
Introduce a basic type system in the language module to support type-checked message passing on the runtime bus. This change adds type definitions and their associated parsing logic, enabling the bus to validate message payloads at compile time rather than relying solely on runtime checks. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>
The `Settings` struct and its associated test module were no longer used anywhere in the codebase. Removing them eliminates dead code and reduces maintenance burden. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>
Return an empty provision set instead of panicking when the provision file does not exist, allowing the runtime to start without a provision file present. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>
The test was asserting that the bus capacity was zero after provisioning, but the correct behaviour is that the capacity should reflect the number of provisioned slots. This change updates the assertion to match the expected post-provision state. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>
When a URI contains consecutive slashes, the path parser now skips empty segments instead of treating them as valid path components. This prevents resolution failures that occurred when empty segments were passed to downstream handlers, aligning the behaviour with common URI parsing conventions. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>
Relax the atomic ordering from SeqCst to AcqRel in the slot allocation path to match the actual synchronisation requirements. The change improves performance on weak-memory architectures while preserving correctness of the lock-free handoff between producer and consumer threads. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>
…nyruntime-bus/src/exec/test.rs, Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>
Remove the test module and types module from the harness, as they are no longer referenced anywhere in the codebase. This cleans up dead code that was left over from an earlier refactoring of the test infrastructure. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>
The `Name` type in the names module was no longer used by any external consumers and was removed to simplify the public API surface. This change eliminates dead code and reduces maintenance overhead. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>
When the key list is empty, the provisioning logic now returns an empty result instead of panicking. This fixes a crash that occurred during startup when no keys are configured, allowing the system to initialize gracefully without requiring at least one key to be present. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>
When deserializing a version struct, the code previously panicked if the version field was absent from the input. This change makes the field optional with a default value, so that missing data is handled gracefully instead of causing a runtime crash. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>
Add the Cargo.toml and lib.rs files for the tinyruntime-bus crate, which were previously missing from the repository. This establishes the crate structure and enables its use as a dependency. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>
The workspace and its crates have been renamed from "template" to "tinyruntime", updating package names, repository URLs, and dependency references throughout Cargo.toml and Cargo.lock to reflect the new project identity. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>
The `Language` type now applies the same trimming and lowercasing during deserialization that its constructor uses, so values received over the wire are normalised before they are used for routing. A derived transparent deserialize would pass the raw string through unchanged, causing a peer that sends "NodeJS" to produce an identifier no provider is registered under. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>
Add test modules to six bus crate components that were previously missing test coverage. This ensures each module has a dedicated test file for future unit testing. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>
Wrap the word "CPython" in backticks in the doc comment for `RuntimeLayout` so that it is rendered as inline code, matching the style used for other tool names in the same comment. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>
Add the full set of runtime dependencies needed for the module to download, verify, and extract toolchain archives, along with the corresponding workspace-level dependency declarations. This includes reqwest for HTTP fetching with rustls, sha2 and hex for archive integrity verification, tar/flate2/xz2/zip for decompression, fs2 for cross-process locking, dirs for platform cache paths, uuid for staging directories, and tracing for diagnostics. The tokio feature set is also expanded to include fs, io-util, process, net, and sync to support the async I/O and concurrency patterns the module requires. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>
The error display implementation now falls back to a default message when the error kind is not set, preventing a panic during formatting. This ensures that errors with uninitialized kind fields are still printable and do not cause runtime crashes. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>
Return an empty result when extracting from an archive that contains no entries, instead of panicking or producing undefined behaviour. This ensures the extraction function behaves correctly for edge cases where the archive is valid but empty. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>
The Cargo.lock file was updated to include new dependencies required by the archive test module, adding crates such as reqwest, sha2, uuid, and various supporting libraries for HTTP, cryptography, and compression functionality. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>
When the server does not send a Content-Length header in the response, the download module now falls back to reading the stream until it ends rather than failing with an error. This improves compatibility with servers that use chunked transfer encoding or omit the header for other reasons. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>
The test module in the download module was not being used and contained no test functions, so it has been removed to keep the codebase clean. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>
The store lock implementation previously allowed a thread holding a read lock to attempt acquiring a write lock, which would cause a deadlock since the write lock waits for all readers to release. The fix ensures that a thread already holding a read lock can upgrade to a write lock without blocking itself. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>
Removed an unused import from the test file to clean up the code and eliminate a compiler warning. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>
Add the serde crate as a dependency in the tinyruntime Cargo.toml to enable serialization and deserialization support for runtime data structures. This change is required by the provider module which now uses serde for configuration handling. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>
When looking up a provider by name in the registry, the code now returns an error if the bus is not set, instead of panicking. This ensures graceful failure when the provider has not been properly initialized with a bus connection. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>
… keys The stub provider previously returned a single-element list containing a default value when a key was not found, which did not match the expected behavior of returning an empty list. This change aligns the stub with the contract defined by the provider trait. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>
The `installing_provider` helper function accepted a `layout_version` parameter that was never used, along with a `TapVersion` trait and its implementation that were only needed to consume that parameter. Removing these simplifies the test code and eliminates dead code. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>
The stub provider now checks for a marker file before reporting a layout, preventing install tests from silently short-circuiting when the target directory does not actually contain the installed toolchain. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>
Remove unused imports from test modules across tinyruntime-bus and tinyruntime to clean up code and eliminate compiler warnings about unused items. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>

In @.github/workflows/ci.yml:
- Line 75: Update the dependency validation command in the CI workflow to
enforce the complete prohibited-dependency policy, covering async runtimes, HTTP
clients, transports, and native libraries rather than only the current fixed
names. Ensure dependencies such as async-std, isahc, surf, and openssl-sys are
detected and cause the job to fail, consistent with the tinyruntime-bus
Cargo.toml policy.
In `@Cargo.toml`:
- Around line 28-29: Update the wire-contract comment in Cargo.toml to reference
crates/tinyruntime instead of crates/template, accurately describing the current
package dependency and re-export relationship.
In `@crates/tinyruntime/src/archive/test.rs`:
- Around line 13-152: Expand the archive tests around extract and single_root to
raise this file’s coverage from 72.6% to at least 90%, adding focused cases for
ArchiveFormat::TarXz and other currently untested extraction branches. Reuse the
existing write_tar_gz, write_zip, extract, and single_root helpers, and verify
both successful extraction and relevant failure paths without broad refactoring.
In `@crates/tinyruntime/src/download/test.rs`:
- Around line 139-152: Replace the port-1 network dependency in
an_unreachable_channel_reports_a_download_failure and the related timeout test
with a test-controlled transport or listener that deterministically returns the
required failure response; remove wall-clock timing assumptions and isolate
timeout behavior from this unit test while preserving the assertions for
download failure and retryability.
In `@crates/tinyruntime/src/exec/mod.rs`:
- Around line 93-118: Update launch_for and its callers so the built Launch,
including provider.harness and env::materialise results, is cached by language
and runtime version before repeated execute requests; ensure cache lookup occurs
before fetching or materialising and reuse the cached Launch on pool reuse.
Correct the launch_for documentation to describe the actual caching behavior
rather than attributing it to Pools::ensure.
In `@crates/tinyruntime/src/pool/env_test.rs`:
- Around line 10-87: Restore the 90% line-coverage gate by adding deterministic
tests for the uncovered worker-environment paths in
crates/tinyruntime/src/pool/env_test.rs:10-87, using the existing build and
materialise/WorkerHarness flows. Add deterministic tests for the uncovered
TinyBus adapter paths in crates/tinyruntime/src/tinybus_module/test.rs:148-358,
covering the branches identified by the coverage report without changing
production behavior.

178: Cover promotion failure, restore failure, discard logging, and cache-root
fallback branches.
In `@crates/tinyruntime/src/pool/env.rs`:
- Around line 78-85: Update materialise to write harness.source to a unique
temporary file within root, then atomically replace the target path only after
the temporary write succeeds. Preserve the existing target file until
replacement completes, and clean up the temporary file if writing or replacement
fails.
In `@crates/tinyruntime/src/pool/lang_pool.rs`:
- Around line 136-141: Update the hard_deadline calculation in the dispatch flow
to apply a finite hard ceiling when timeout is None, while retaining the
existing timeout-plus-WEDGED_GRACE behavior for timed jobs. Define and use a
clear constant alongside WEDGED_GRACE so every Worker::await_response invocation
is bounded.
In `@crates/tinyruntime/src/pool/mod.rs`:
- Around line 71-84: Update Pools::ensure’s reuse fingerprint to include a
stable WorkerHarness::source content digest or provider harness revision via
Launch::fingerprint, so changes to harness contents invalidate the existing pool
and cause workers to rebuild while preserving reuse when the value is unchanged.
In `@crates/tinyruntime/src/resolve/mod.rs`:
- Around line 183-194: Update memo_key to use an unambiguous typed key instead
of concatenating fields with "|" separators. Define a private key type
containing the language and all RuntimeSettings values used by memoization,
deriving the required equality and hashing traits, and update memoization call
sites to use it while preserving distinct keys for distinct settings.
In `@crates/tinyruntime/src/resolve/test.rs`:
- Around line 300-341: Rename
an_install_that_produces_no_toolchain_is_reported_as_such to describe the
file:// download failure, and remove its unused archive setup unless reused. Add
a separate test using a local HTTP listener to serve the archive, exercise
extraction and promotion, and assert the resolver returns Error::EmptyInstall;
reuse write_single_root_tarball for that test.
In `@crates/tinyruntime/src/store/lock.rs`:
- Line 40: Replace the version-colliding Path::with_extension derivation in
crates/tinyruntime/src/store/lock.rs:40 by appending ".lock" to
install_dir.file_name() and applying it with with_file_name. Also update the
aside-path construction in crates/tinyruntime/src/store/mod.rs:145-156 to append
".replaced-<pid>" to destination.file_name() via with_file_name, ensuring
the unconditional remove_dir_all targets only that install’s displaced tree.
In `@MODULE.md`:
- Around line 65-66: Update the installation documentation so it does not
present the v0.1.0 archive command as available before the release asset exists;
either publish the v0.1.0 release and retain the command, or clearly mark the
command unavailable until publication.
In `@README.md`:
- Around line 52-55: Update the README passage to distinguish per-request
runtime-selection settings from module-wide configuration: provider routing via
providers and harness location via harness_dir are loaded at module
initialization, while each request supplies the settings used for runtime
selection.
---
Outside diff comments:
In `@crates/tinyruntime/src/tinybus_module/README.md`:
- Around line 1-21: Update the README to document the current RuntimeService
adapter instead of the removed greeting example: replace
GreetingService/greet/Greet references with RuntimeService and its Languages,
Resolve, Execute, and PoolStats methods, use tinyruntime_bus::names for the
method-name source, and point the verification example to the tinyruntime
verify_module example. Preserve the existing ABI, manifest-alignment, loader,
and generated-project guidance.

Nitpick comments:
In `@crates/tinyruntime/src/pool/worker_test.rs`:
- Around line 120-134: Update
a_worker_that_never_connects_back_fails_rather_than_hanging to use
std::env::current_exe() as the launched binary, removing the platform-specific
binary selection and early-return skip. Preserve the test’s no-connection
behavior and handshake_timeout assertion while configuring arguments as needed
for the current executable.
In `@crates/tinyruntime/src/pool/worker.rs`:
- Around line 343-370: Update verify_handshake to validate Handshake::language
against launch.language when the worker provides a language value, rejecting
mismatches while preserving the existing checks and accepting an omitted worker
language.
- Around line 406-408: Align the pool unit-test layout with the documented
convention by replacing the `worker_test.rs` path attachment in the `test`
module with the module-local `src/pool/test.rs` arrangement, preserving access
to private items and existing test coverage.
- Around line 189-198: Update spawn’s listener-accept flow around read_handshake
and verify_handshake to keep accepting loopback connections until one presents a
valid token or the overall handshake timeout expires. Reject invalid connections
and continue within the remaining timeout budget, while preserving the existing
success path once verify_handshake passes and returning the timeout/error when
no valid worker connects.
In `@crates/tinyruntime/src/resolve/reuse.rs`:
- Around line 32-47: Update the directory scan in the surrounding async resolver
to use tokio::fs::read_dir(root).await and iterate with next_entry().await,
returning None on traversal errors instead of silently skipping them. Keep
entry.file_type() synchronous and preserve the existing directory, staging, and
store::is_inside filters when collecting candidates.
In `@crates/tinyruntime/src/store/lock.rs`:
- Around line 36-67: Update acquire to use try_lock_exclusive with a bounded
retry loop and delay between attempts, returning a retryable Error::Install when
the lock remains unavailable instead of blocking indefinitely. Extend acquire’s
# Errors documentation to include Error::Storage for directory-creation
failures.

🚀 Performance & Scalability | 🟠 Major | ⚡ Quick win
launch_for runs the harness fetch and harness write on every job, not once per toolchain.
The doc comment states that Pools::ensure makes this run once per toolchain. execute calls launch_for before Pools::ensure, so provider.harness() (a bus round trip) and env::materialise (a filesystem write) run for every ExecRequest. Pool reuse only avoids the worker spawn.
Cache the built Launch per language and runtime version, and correct the doc comment.

Make the memo key unambiguous.
memo_key joins the fields with |. Any field value that contains | can produce the same key as a different field combination. cache_dir, release_tag, and preferred_command are host-supplied strings, so this is reachable through configuration. A collision returns the toolchain resolved for other settings, which is the exact outcome the doc comment at Lines 43-45 says the key prevents.
Use a key that cannot be ambiguous.

}A private key struct that derives Hash and Eq would also remove the string entirely, which matches the "prefer small, typed APIs over stringly-typed ones" rule in the coding guidelines.

Path::with_extension is used to derive sibling paths from version-shaped directory names. with_extension replaces the last dot-separated segment instead of appending, so node-v22.11.0 and node-v22.11.1 collapse to one derived path. That breaks lock scoping and makes the displaced-install path ambiguous.

When a parked worker's child process exits while idle, the pool now checks for that before dispatching a new job. Previously the death was only discovered after writing the job, and because a TCP write into a closed peer's buffer succeeds, the error arrived at the read phase where it was classified as terminal and the job was never retried.

Add two new tests to the pool environment test suite: one verifying that a harness which cannot be written due to a file blocking the directory reports a storage error, and another confirming that a worker without an inherited PATH still receives the toolchain directory in its environment.

Add three new integration tests covering the router's exec path and cached resolve behaviour. The first test verifies that a host can run code through the router over the bus end-to-end, including pool stats reporting. The second test ensures that attempting to execute code for a language with no provider fails with a readable error. The third test confirms that a cached toolchain install is reported through the router's resolve method. Also simplify the existing unrouted language test by using expect_err instead of a manual match. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>

…chain Replace the static test fixtures in the fake provider with a host toolchain that re-executes the test binary as a worker, removing the dependency on Node being installed. The layout method now echoes the request directory back through the version field so tests can verify the request crossed the bus, and the diagnostic resolve call is removed as it is no longer needed.

…ocking helper Extract the common pattern of spawning a blocking task and unwrapping its join error into a reusable `crate::blocking::run` function, reducing boilerplate and making the error handling consistent across archive extraction, install locking, and store promotion. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>
Add a `tracing` subscriber that enables all levels and discards every record, ensuring that field expressions in log macros are actually evaluated during tests. Without a subscriber, `tracing` short-circuits before formatting, which can hide panics in field expressions until they occur in production. The new `evaluate_log_fields` helper is called at the start of every test, and `cache_root` is refactored into `cache_root_under` to make the platform-cache fallback testable without environment manipulation.

Move a `use` statement for `PermissionsExt` to the top of the test file and add crate-level `allow` attributes for clippy lints in the fake worker and testing modules. The `PermissionsExt` import was previously inside two test functions and is now hoisted to module scope, while the clippy suppressions prevent false positives in test and simulation code that intentionally uses unwrap and panic.

Extract the repeated `Error::Install` construction into a local helper function in two modules, reducing boilerplate for unreachable IO failures. Add a constant for the unknown archive format error message and a test that verifies a truncated transfer is reported and the partial file is removed. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>
…re modes The retry-on-pre-dispatch-failure logic in LangPool::dispatch was removed because a parked worker whose process has exited is now caught before the write by Worker::has_exited, and a graceful close leaves the socket writable so a write to a dead peer succeeds with failure only surfacing at read—by which point the job must never be re-run. New tests cover a worker whose socket dies, a worker that cannot be started, workers that send no handshake or garbage, and a pool with reaping disabled. The fake worker gained a Linger directive and launch_with_mode helper to support these scenarios, and the stub provider gained a failing-layout mode for resolution tests. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>
When decompressing an archive that contains no entries, the previous code would attempt to iterate over an empty list and return an error. This change adds an early return for empty archives, allowing decompression to succeed gracefully without processing any entries. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>
Replace the string-based worker misbehaviour markers with a typed enum, and factor out a shared error formatting function for read failures. The archive module's unknown-format error is also simplified by calling a dedicated helper instead of inlining the error construction. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>
The `unknown_format` helper was only used in one place and added unnecessary indirection. Inlined it directly into the match arm, keeping the explanatory comment that was previously on the function. This also removes a function that existed solely to satisfy a non-exhaustive enum match. test(pool): add in-process tests for worker connection modes Extracted the connection and serving logic from `serve()` into a new `connect_and_serve()` function that accepts its parameters directly, making it testable without manipulating process environment variables. Added tests for Silent, Garbage, and Serve modes over real TCP sockets, and a test verifying that directives which change process exit behaviour still produce a reply before the process ends. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>
The catch-all arm for unknown archive formats now returns an `io::Error` instead of an early `Error::Install`, aligning it with the error mapping used by the other match arms. This keeps the error handling consistent and reduces the branch to a single expression. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>
The hang and linger directives now keep a worker unresponsive for 25 seconds instead of 120. This is still comfortably longer than any test deadline, ensuring the pool's grace period always ends the wait, but avoids turning a ten-second test suite into a two-minute one under parallel runs. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>
A semicolon was missing after the call to `connect_and_serve` inside the test's thread spawn closure, which caused a compiler warning about the unused result. Adding the semicolon makes the expression a statement and silences the warning. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>

Read layout_fails in layout and return Error::ProviderUnavailable.
with_failing_layout sets layout_fails, but layout does not read it. The configured stub returns Ok(None) instead of exercising the provider-error path in a_cached_directory_the_provider_errors_on_is_skipped.

The leading comment contradicts the test.
Lines 575-576 state that the scan must not abort. The test asserts found.is_err(), so the resolution does abort. The comment appears to be copied from the two preceding skip tests. Lines 587-588 already give the correct reason.
📝 Proposed comment fix
async fn a_provider_that_is_down_entirely_fails_the_resolution() {
- // One unreadable leftover must not abort the scan and hide the install
- // sitting next to it.
+ // A provider that answers nothing is different from one that declines a
+ // directory: the resolution fails rather than reporting "not installed".

What changed
Replaces the template with
tinyruntime: a TinyBus module that resolves alanguage runtime, installs one when the host has none, reuses one when it does,
and runs code on a bounded pool of warm interpreter processes.
Every host that wants to run a bit of JavaScript or Python needs the same
unglamorous machinery — find a compatible interpreter or download one, verify it,
unpack it somewhere durable, notice next time that it is already there, and then
not pay tens of megabytes of resident memory per execution. That machinery is
identical for every language and gets reimplemented, slightly differently and
slightly wrongly, once per host. This is that machinery, once, behind a bus.
The split
This repository is the router and contains no language knowledge. A
grepfor
nodeorpythonundercrates/tinyruntime/srcthat finds anything otherthan a comment is a bug. Providers answer five questions; the router does
everything those answers imply.
crates/tinyruntime-bus— the wire contract. Two pure-Rust dependencies, notransport. Defines both interfaces, because the router consumes the provider
interface exactly as a host consumes the router's.
crates/tinyruntime— the router: resolution order, download with mandatorydigest verification, extraction, atomic promotion, cross-process install
locking, cache reuse, and the warm worker pool.
Resolution order
Each step exists to avoid the cost of the next: process memo → host interpreter →
cached install → download. The first three never touch the network, which is what
makes a non-installing probe worth calling.
Properties worth reviewing
this host runs code with. A mismatched archive is deleted rather than left where
a later run might reuse it.
install directory, plus a re-check after acquiring it, so the loser finds the
winner's work instead of downloading hundreds of megabytes to overwrite it.
failure restores what was there.
reached the worker; only one that provably never left is retried.
authenticated loopback socket, never the job's own stdout.
callers not to fall back to spawning their own interpreter.
Public API / behaviour changes

Languagedecodes through a manualDeserialize. A derived#[serde(transparent)]skips normalisation, so a peer spelling"NodeJS"onthe wire would arrive as an identifier no provider is registered under and fail
to route. There is a test that fails without it.
tinybus_module!builds a module's manifest object path from its bus name, soproviders sharing one path would ship manifests disagreeing with the objects
they export — invisible to in-process tests.
names::object_path_forappliesthe same derivation, and
each_provider_is_addressed_at_its_own_object_pathcovers it with two providers on one bus.
provider/stub.rsanswers the fivequestions from memory, so resolution, reuse, install, and execution are
exercised without a second module, a release channel, or a network.
Follow-ups (deliberately not in this PR)
npm/pip) is reported in a layout but nothing callsit; whether that belongs behind a member here is an open contract question.
Depends on nothing.
tinyruntime-nodejs,tinyruntime-python, and the openhumanintegration all pin this branch as a submodule and should land after it.
Summary by CodeRabbit
Update — the 90%-per-file coverage gate
The first CI run failed this gate, which I had not run locally. Closing it took
real work rather than a threshold change, and two of the things it forced are
worth calling out in review:
A defect the tests found. A parked worker whose process had died was
classified post-dispatch and the job failed terminally — even though it
provably never ran. The cause is TCP: a write into a closed peer's buffer
succeeds, so the failure only surfaces at the read, by which point the job counts
as dispatched.
Worker::has_exitednow checks before the write, turning that caseinto a transparent respawn. The pre-dispatch retry inside
dispatchwas thendead code for this transport and has been removed, with a comment explaining why.
A real worker, not a mock.
pool/fake_worker.rsre-executes the test binaryas an interpreter, so the handshake, warm reuse, recycling, backpressure, the
install pipeline, and
Engine::executeare all exercised against a genuine childprocess over a genuine socket — with no dependency on Node or Python being
installed.
Where a branch was unreachable rather than untested, I changed the code rather
than the gate:
cfg!(windows)branches became parameters (bin_dir_for,executable_name_for,windows_executable), so the Windows layout is checked on Linux instead of onno machine at all.
tested against a loopback server rather than nodejs.org or GitHub.
cache_root_undertakes the platform cache, so the last-resort fallback isordinary to exercise.
spawn_blockingjoin-failure arms collapsed into one tested helper(
blocking::run), reachable by handing it a panicking task.tracingfield expressions, whichboth covers those lines and proves a log field cannot panic.
All four contract commands plus the coverage gate now pass on all three module
repositories.
