Read the host's source registry file, not an invented path - #109

The module built its engine config with `config_path =
workspace_dir/config.toml`. No host writes that file: OpenHuman keeps
`config.toml` beside the `workspace/` directory, and that is where every
`[[memory_sources]]` entry the user adds lands. So `get_source_in` — the
lookup behind `run_source_sync` — read an empty registry and answered
`NotFound("no memory source registered as src_…")` for every source of
every kind, which is the strand reported in openhuman#5820 and reproduced
today on a healthy store by adding a folder source and pressing Sync.
- `ModuleConfig` gains an optional `config_path` the host sends; an older
host deserializes it as `None`.
- `provider::host_config_path` resolves it: the host's value first, then
`config.toml` beside the workspace when that file exists (the documented
layout), then the historical path so a host with neither is unchanged.
- `EngineRuntimeConfig::memory_sources_json` answers from that file when it
exists, so a source added after the module loaded is visible to the
in-module sync loops instead of only to a load-time snapshot; the
snapshot remains the answer with no file or a failed read.
- `sources::registry::list_sources_in` is the explicit-config twin of
`get_source_in` that the live read goes through.

function documentation, stating that it returns Err(String) when the registry
TOML file is malformed or unreadable, with the failure message converted to a
string. Do not alter the registry lookup or error-handling implementation.

- Around line 271-285: Update EngineRuntimeConfig::set_memory_sources_json and
save so changes are written to the live registry at config_path when it exists,
keeping memory_sources synchronized for snapshot-only configurations. Ensure
memory_sources_json returns a setter-updated registry value, and add a
deterministic regression test using an existing registry file that verifies
setter, getter, and persistence behavior.

Review follow-up: with `memory_sources_json` reading the registry file live, a `set_memory_sources_json` that only updated the in-memory snapshot was invisible to the very next getter, and `save` on this config is a no-op, so the in-module caps migration never persisted. `SourceRegistry::replace_all` (validate each entry, same atomic load-modify-save cycle, other keys kept) backs a new `registry::replace_sources_in`, and the engine config's setter writes through to the file when there is one, keeping the snapshot for a config without a file. Regression test covers set → live get → on disk, plus the snapshot-only path. `list_sources_in` gains its `# Errors` section.

…e registry) Second re-pin of this PR, same five sites plus both Cargo.locks: the vendor/tinymemory gitlink to the v1.13.1 tag commit, `modules/registry.rs` (version, release_url, all 11 digests from the release's checksum.toml), the four workflow `memory_version`/`memory_sha256` pairs, and `ARTIFACT_CAPABILITIES_PIN`. The capability surface is unchanged since v1.12.0 (empty diff on capabilities.rs and the module's lib.rs). v1.13.1 carries tinyhumansai/tinymemory#109: the module now reads the `config_path` this host sends instead of an invented `workspace_dir/config.toml`, so per-source sync no longer answers `no memory source registered as src_…` — the strand in tinyhumansai#5820.

Summary
The module built its engine config with
config_path = workspace_dir/config.toml. No host writes that file — OpenHuman keepsconfig.tomlbeside theworkspace/directory, and that is where every[[memory_sources]]entry a user adds lands. Soget_source_in, the lookup behindrun_source_sync, read an empty registry and answeredNotFound("no memory source registered as src_…")for every source of every kind. That is the strand reported in tinyhumansai/openhuman#5820, and it reproduces today on a perfectly healthy store: add a folder source, press Sync.Three small changes make the module read the host's file:
ModuleConfiggains an optionalconfig_paththe host sends (openhuman's paired change adds it to the load payload). A host too old to send it deserializesNone.provider::host_config_pathresolves the engine'sconfig_path: the host's value first; for an old host,config.tomlbeside the workspace when that file exists (the documented profile layout); otherwise the historical path, so a host with neither is unchanged.EngineRuntimeConfig::memory_sources_jsonanswers from that file when it exists, so a source added after the module loaded is visible to the in-module sync loops rather than only to the load-time snapshot. The snapshot remains the answer with no file or a failed read.sources::registry::list_sources_inis the explicit-config twin ofget_source_inthis goes through.Related issue

API or behavior changes
Additive only:
ModuleConfig.config_path: Option<PathBuf>(#[serde(default)]),sources::registry::list_sources_in. Behavior: with the corrected path, module-side registry reads and writes (upsert_composio_sourcefrom the in-module reconcile) now target the host'sconfig.toml— the same file the host writes through the sameSourceRegistry(atomic temp-file + rename, owner-only). The two sides do not share the in-process mutation lock, so a simultaneous host write and module write can lose one update; the rename keeps the file intact. That window existed for the host's own two loops before and is rare (reconcile at boot).Validation
