fix(modules): load callback-bound modules from the verified release, not only a local file - #8535
Modules that take host callbacks (TinySecurity, TinyMCP, TinyEventQueues, TinyChannels, TinyComputer) now load from the pinned release on hosts without OPENHUMAN_MODULE_PATH. Before this, they needed a local-file override.
Every callback load now goes through TinyBus's Resolver::ensure_loaded_with_host_callback_factory, which already walks the release chain with callbacks: installer bundle, then the release cache, then a download into it. It checks the archive SHA-256 and, when the record pins one, the library SHA-256 before the module gets a binding.
A later load of a module that is already admitted now confirms the binding it kept (callback_load::confirm) instead of offering it a second time.
Callback loads run on the process-owned module runtime (callback_load::detached). A caller's timeout (for example TinyComputer's 8 s) drops only its wait, never the admission or the publication of the binding's host state. The task is scheduled before the bus finishes installing its callbacks, and it carries the caller's CoreContext.
No TinyBus change and no vendor move. OpenHuman was calling the one TinyBus API that only accepts a local file.
Problem
ops::ensure_loaded_with_storage_callback, ensure_loaded_with_computer_callback and the repeat path in security::host_callbacks::ensure_loaded all called Resolver::ensure_loaded_with_host_callbacks. That is the single-binding API, and it refuses any source that is not ModuleSource::LocalFile with "module '{id}' host callbacks require a verified local-file source".
ops::resolver gives these modules a LocalFile source only when source::local_artifact finds an OPENHUMAN_MODULE_SOURCE_DIR build or an OPENHUMAN_MODULE_PATH artifact. Shipped builds and embedders have neither, so the source is the release:
TinyMCP, TinyEventQueues and TinyChannels failed their first load.
TinyComputer failed its first load too (security-module builds).
TinySecurity's first load already used the factory and worked. After that, every security::ensure_loaded re-presented the binding through the single-binding API and failed. This is the "downloads and digest-verifies fine, then every callback-bound call fails" report.
Exporting OPENHUMAN_MODULE_PATH at the release cache made it work only because that turned the source into LocalFile.
Solution
New modules/ops/callback_load.rs:
load(resolver, id, prepare) prepares a fresh binding and its host state (storage endpoint, consequence host) for each candidate artifact. It keeps the state of the candidate that was admitted and drops the rest. A refused candidate revokes only its own binding.
confirm(resolver, id, binding) checks that the admitted module still holds binding, without preparing anything or touching a source.
The storage, computer and security callback loads use these two functions. Per-module configuration (storage_callback, consequence_host, the security config) is built per candidate, the same way TinySecurity's first load already did it.
Resolution order for a callback-bound module is now:
a [[modules.overrides]] path, then OPENHUMAN_MODULE_SOURCE_DIR, then OPENHUMAN_MODULE_PATH (as LocalFile, unchanged);
otherwise the pinned release: installer bundle (set_bundled_releases_dir / OPENHUMAN_BUNDLED_MODULES / bundled-modules/). A bundled artifact that fails its pin is refused with "repair the installation" and does not fall back to the cache;
then the release cache under ops::install_dir;
then a download into that cache when modules.allow_download is on.
Every rung after the overrides is digest-checked by TinyBus before the binding is offered.
Why the fix is in OpenHuman and not TinyBus: TinyBus already does bundle/cache/download/verify with callbacks (load_first_admitted_with_host_callbacks, reached through the factory API), and covers it in first_admitted_tests.rs. Adding a resolver source that turns the release into a local file would duplicate that chain.
Tests
New modules/ops_callback_release_tests.rs. It stages tests/fixtures/storage_probe_module (built by the storage-host cdylib tests, whose probe_artifact is now shared) as a release: a tar.gz archive and its extracted library under <root>/<id>/<version>/<host key>/. A record pins both digests. Each test runs in its own process, like a_faulted_module_is_not_retried_in_process.

Every failure here also fails on main (registry::contract_tests x2, which is the module-pins work in flight; boot_skips_disabled_components; plus two TinyDocs tests that fail only inside the full suite).

Submission Checklist
Tests added or updated (happy path + failure/edge cases)
Diff coverage ≥ 80%: callback_load.rs and the storage callback path are exercised by ops_callback_release_tests.rs. The TinyComputer branch is the same two calls, behind security-module, and the diff-cover lane checks it
Coverage matrix updated: N/A, behaviour fix with no feature row change
Affected feature IDs: N/A
No new external network dependencies (fixtures are local; downloads off in every test)
Manual smoke checklist: N/A
Linked issue: N/A, no tracking issue filed
Impact
Desktop, CLI, Docker and embedders: callback-bound modules work from the bundled or cached release with no host workaround. OPENHUMAN_MODULE_PATH is no longer needed for them.
Security: the "verified" property stays. Callbacks are bound only to an artifact that matches the registry's archive digest (and library digest when pinned), or to an explicit local override, as before.
Public API or behaviour change: none outside modules. ops::callback_load is pub(super).

Bug Fixes
Callback modules retain and reuse the binding accepted during loading, and reject attempts to confirm a different binding.
Release bundles and cached libraries with digests that do not match their release records are refused. Local-file overrides continue to take precedence over pinned releases.
Module loading can continue if the initial caller stops waiting, allowing a later caller to find the loaded module.

The serving_with_callbacks helper now takes the resolver and checks that a
loaded module answers with the same retained host callback binding its load
prepared, rather than only checking that some binding exists. This makes the
release tests assert that reloads confirm the existing binding instead of
re-presenting it.

Moves the storage and computer callback load sequences into a new

Host callback loading now verifies that an already-admitted module still holds its binding rather than presenting the binding again, since a spent binding is refused and the single-binding path only accepts local-file sources, which broke every later call for host-served releases.

Pull request purpose (title): fix(modules): load callback-bound modules from the verified release, not only a local file. Callback-bound modules (TinySecurity, TinyMCP, TinyEventQueues, TinyChannels, TinyComputer) previously failed on hosts without a local-file override with "host callbacks require a verified local-file source", because they were loaded through the single-binding API that accepts only a local file. This pull request routes those loads through a new `callback_load` module (`load`, `confirm`, `detached`) over `Resolver::ensure_loaded_with_host_callback_factory`, so a release-served module loads from the installer bundle, the digest-verified release cache, or a download, and later loads confirm the binding already admitted. The latest-push-delta section is unavailable, so no push delta is described.

What changed
Callback-bound module loading is extracted into `crates/openhuman-core/src/modules/ops/callback_load.rs`: `load` prepares a fresh binding and host state per candidate artifact and retains only the admitted candidate's state, `confirm` re-checks an already-admitted binding without touching a source, and `detached` runs the work on the module bus executor so a caller that stops waiting loses only its wait, not the admission or the publication of the binding's host state. `detached` now captures and propagates the caller's `CoreContext` and spawns through a new `spawn_on_bus` in `crates/openhuman-core/src/modules/runtime.rs`, so the task awaits bus start itself. `ensure_loaded_with_storage_callback` and `ensure_loaded_with_computer_callback` in `ops.rs` delegate to `detached`, with the load bodies moved into `callback_load::load_with_storage_callback` and `callback_load::load_with_computer_callback`; `ensure_loaded_with_security_callback` wraps `security::host_callbacks::ensure_loaded` the same way, and that repeat path now confirms the admitted binding instead of re-presenting it. The resolver comment in `ops.rs` documents that a staged artifact still wins as a local file, otherwise the pinned release serves from the bundle or the digest-verified cache. Test-visibility bumps in `storage_host.rs`, `storage_host_cdylib_tests.rs`, and `storage_host_tests.rs` share the probe fixture, and `ops_callback_release_tests.rs` adds process-isolated tests for the bundled, cached, override, digest-refusal, binding-mismatch, cancelled-caller, and caller-context paths. The README documents the new resolution order.
Features
Added — Callback-bound module load helper (`callback_load::load`): Prepares a fresh host-callback binding and host state for each candidate artifact the resolver tries, keeping the admitted candidate's state and dropping refused candidates', so a release-served module can be admitted without a local-file override. (crates/openhuman-core/src/modules/ops/callback_load.rs)
Added — Callback binding confirmation helper (`callback_load::confirm`): Re-checks that an already-admitted module still holds its binding without preparing anything or touching a source, so later loads of release-served modules no longer fail with the local-file-source refusal. (crates/openhuman-core/src/modules/ops/callback_load.rs)
Added — Detached callback load runner (`callback_load::detached`): Runs a callback load on the module runtime and waits for it; the task is scheduled before any await and carries the caller's `CoreContext`, so a caller that gives up drops only its wait and cannot strand the admitted binding's host state. (crates/openhuman-core/src/modules/ops/callback_load.rs)
Added — Module bus task spawning (`spawn_on_bus`): Adds `spawn_on_bus`, which starts the module bus without awaiting its host callbacks and hands back a join handle for a task that outlives the caller that spawned it. (crates/openhuman-core/src/modules/runtime.rswhere)
Modified — Storage and computer callback load paths: `ensure_loaded_with_storage_callback` and `ensure_loaded_with_computer_callback` now run their load bodies through `callback_load::detached`, confirming the retained binding on later loads, so storage- and computer-backed modules load from the bundled or cached release. (crates/openhuman-core/src/modules/ops.rsasync fn ensure_loaded_with_computer_callback(, crates/openhuman-core/src/modules/ops/callback_load.rs)
Modified — Security callback load and repeat path: The security callback load runs through `callback_load::detached`, and the repeat path confirms the admitted binding instead of re-presenting it through the single-binding API, fixing every later callback-bound call on release-served hosts. (crates/openhuman-core/src/modules/ops.rsasync fn ensure_loaded_with_security_callback(, crates/openhuman-core/src/modules/security/host_callbacks.rspub(in crate::modules) async fn ensure_loaded()
Modified — Resolver source comment for callback-bound modules: Documents that a staged artifact wins as a local file and otherwise the pinned release is served from the installer bundle or the digest-verified release cache. (crates/openhuman-core/src/modules/ops.rspub fn resolver(config: &Config) -> Resolver {)
Modified — Module README resolution documentation: Documents that callback-bound modules load through `ops/callback_load.rs` with the override, bundle, cache, then download order. (crates/openhuman-core/src/modules/README.mddownload, its `dlopen`, or its resident memory.)

description
Conclusion: Success
Scope reviewed: all assigned evidence
Lane summary: The description matches what the code does: the new `modules/ops/callback_load.rs` provides `detached`, `load` and `confirm` over `Resolver::ensure_loaded_with_host_callback_factory`; the storage, computer and security paths now go through them; `ops::resolver`'s comment update and the `probe_artifact`/test-module visibility changes are all reflected in the body; and the new `ops_callback_release_tests.rs` contains the seven scenarios the table names (the extra `a_detached_callback_load_runs_under_the_callers_context` test simply backs the undetached-context claim the body already makes). The only thing I could not verify is the TinyBus side — `vendor/tinybus` is not checked out, so the quoted error strings and the factory's candidate/verification semantics are taken from the body and tests rather than read from the dependency. No description/behaviour mismatch worth a finding. _The code index is behind this pull request (indexed at `8335c08765d6`), so retrieved context may be out of date._
Storage, security, and computer callback loads now run as detached tasks and use shared helpers to prepare or confirm bindings. New process-isolated tests cover release resolution, binding reuse, timeout behavior, digest checks, and local-file loading.

Boot admits tinychannels and tinycomputer artifacts without their host callback bindings.
73-76: 🎯 Functional Correctness | 🟠 Major | 🏗️ Heavy lift
Boot admits tinychannels and tinycomputer artifacts without their host callback bindings.
The boot search-path loader admits staged tinychannels and tinycomputer artifacts through load_dir or load_file, with no callback binding (crates/openhuman-core/src/modules/search_path.rs:128-133). tinychannels requires the storage callback (ops.rs, needs_storage_callback). A module that is already admitted cannot receive a binding through the callback-aware load (ops/callback_load.rs:1-22). A module admitted this way can run without the callbacks it needs. tinymcp and tinyeventqueues have the same boot-admission gap through load_file_with_config (search_path.rs:122). This admission path predates this PR.
Correct the admission behavior for all four IDs. Callback-dependent modules must not be admitted at boot without a binding. Their staged artifacts must stay discoverable, and their first admission must go through callback-aware loading. Discovery must cover OPENHUMAN_MODULE_PATH and the supported platform data directories.
Adding these IDs to the skip lists does not meet this goal. local_artifact (source.rs) searches only OPENHUMAN_MODULE_PATH. The resolver's search_skip (ops.rs) does not list tinychannels or tinycomputer. Platform-directory discovery depends on TinyBus source that is not in this checkout, so the routing change needs that source for review.
Effort is high. The change spans the boot loader, the resolver source routing, and artifact discovery.

Update the boot admission flow using load_dir, load_file, and
load_file_with_config so tinychannels, tinycomputer, tinymcp, and
tinyeventqueues are first admitted through callback-aware loading with their
required bindings. Preserve discovery of staged artifacts through
OPENHUMAN_MODULE_PATH and supported platform data directories; coordinate
resolver source routing and artifact discovery with the TinyBus source needed to
verify platform-directory behavior. Do not rely on skip lists or local_artifact
alone, since they do not satisfy the discovery and callback-binding
requirements.
Add a test for the download branch of the release callback load.
Add a test for the download branch of the release callback load.
The release callback tests disable downloads. resolver() in crates/openhuman-core/src/modules/ops_callback_release_tests.rs:167 sets allow_download: false, and no test in the modules tree runs a callback-bound load with downloads enabled. The release tests cover the installer bundle, the release cache, pin mismatches, and local overrides.
A cache miss that downloads a pinned release, followed by a retained callback binding, is not tested. This path runs in TinyBus before the binding is offered. The openhuman closure in callback_load::load does not depend on the candidate source, so a test on that path would also need to check the download step.
Add a test that sets allow_download: true in a variant of the fixture. Serve the pinned release from an empty cache and assert that serving_with_callbacks succeeds. The download source needs a test seam, such as a local release server or an injectable download URL. The available source does not show such a seam.

Add a release-callback test using a fixture variant of resolver() with downloads

safe test seam for the download source, such as an existing local-server or
injectable-URL mechanism; do not assume an unavailable API or rely on an
external release service.

Add a presence check for storage_callback in the release test path.
ensure_loaded_with_storage_callback writes storage_callback into the module configuration at ops.rs:289, inside the closure passed to callback_load::load. The release tests do not check that entry. The probe's setup never reads its module configuration. serving_with_callbacks compares only the retained binding's unique_name() and checks the bus listing. Removing or renaming the write leaves these tests green.
Assert that the module configuration built at ops.rs:288-290 contains storage_callback equal to the retained binding's unique_name(). The probe can report the configuration it receives, or the test can capture the value at that boundary. Run the check on the same production load path that the release tests already exercise. Do not add an extraction whose independent unit test leaves this caller path untested.

Add a regression test asserting that when a caller's wait on a callback module load times out, the admitted binding's host state is not stranded and the next caller finds the module serving.

Callback-bound module loads now run on the module runtime via a new detached helper, so a caller that times out or drops its future no longer cancels the load and strands the binding's host state in the process-wide cache. The next caller would otherwise find the module serving with a binding nobody holds state for.

The test now brings up the module bus before triggering the load, since boot starts it in the core and its absence was not the thing the caller was meant to give up on.

The ops.rs entry now explains that callback modules load on the module runtime, with `load` for the storage and computer first loads and `confirm` for later ones, and notes that TinySecurity prepares its own per-candidate state over the same resolver. The shared resolution order for overrides, bundle, cache, and download is spelled out for each path.

Make the abandoned-load test prove that the first binding survived.
With Duration::ZERO, the first caller can stop before its load starts. In that case the second call performs a fresh load, and both final assertions still pass. serving_with_callbacks compares against the binding currently stored for ID, so it cannot tell the first admitted binding from a new one. The assertion message says the second caller reuses the first load, but no check verifies that.
Record the admitted binding's unique name before the second call, then assert that the name is unchanged after it. The first load must also reach admission before the first caller is dropped. The STORAGE_CALLBACK_LOADS entry is inserted only after the load returns, and the mutex is held across the load, so waiting on that entry does not show admission. Add an observation point for admission first, then drop the caller after it.

Update the abandoned-load test around ensure_loaded_with_storage_callback to
observe the first load reaching admission before dropping its caller; use an
observation point that signals actual admission, not the STORAGE_CALLBACK_LOADS
entry added after the load returns. Record the admitted binding’s unique name
before the second call and assert that name is unchanged afterward, proving the
second caller reused the first binding.
Adds a test asserting that work spawned on the module runtime during a detached callback load runs under the caller's context rather than the process default, since the first load reads ambient profile, agent, and storage scope.

Callback loads now spawn on the module bus before awaiting its runtime, so a caller that times out while host callbacks are still installing no longer cancels the load, and the work runs under the caller's propagated CoreContext so TinySecurity's first load can resolve its secret scope.

Relocated the storage and computer callback load functions out of ops.rs into the callback_load submodule so the callback loading logic lives alongside its supporting helpers. Behaviour is unchanged; the call sites now delegate to the moved functions.

Reordered the imports in callback_load.rs and reflowed the consequence callback binding expression to satisfy rustfmt. No behaviour change.

Make the zero-timeout test confirm the first load before the second call.
The test does not detect a regression in which the abandoned first call never starts its load. In that case the second call performs the entire load, and both assertions still pass. The assertion message says the next caller finds the load that the first caller started, but no assertion checks that the first load was started.
Add a bounded wait for the entry before the second call. The wait fails if the entry never appears.

Unverified finding
We couldn't verify this from the code. It is shown for review, not as a verified issue.
Once the caller drops its wait for task, a subsequent runtime-installation or callback-preparation error has no receiver in this wrapper and may go unreported.
The module remains unavailable without an error reaching that caller or, potentially, an operational failure signal.
This can occur when: A caller times out, then the detached task fails before publishing a callback binding.

Summary
OPENHUMAN_MODULE_PATH. Before this, they needed a local-file override.Resolver::ensure_loaded_with_host_callback_factory, which already walks the release chain with callbacks: installer bundle, then the release cache, then a download into it. It checks the archive SHA-256 and, when the record pins one, the library SHA-256 before the module gets a binding.callback_load::confirm) instead of offering it a second time.callback_load::detached). A caller's timeout (for example TinyComputer's 8 s) drops only its wait, never the admission or the publication of the binding's host state. The task is scheduled before the bus finishes installing its callbacks, and it carries the caller'sCoreContext.Problem
