`FolderReader` ignored the `MemoryConfig` it is handed — `_config`, with
`PathBuf::from(base_path)` used verbatim. A relative path therefore resolved
against the host process's working directory, which is whatever directory the
process happened to start in. For the OpenHuman desktop app that is the Tauri
build directory, so a source configured as `docs` looked in
`.../app/src-tauri/docs`, found nothing, and failed on every sync cycle forever
for a source that could work.
Relative paths now anchor on `MemoryConfig::workspace` — the root this crate
already treats as authoritative. Absolute paths are taken verbatim, so every
source configured today resolves exactly where it does now;
`an_absolute_path_ignores_the_workspace` pins that against a workspace sharing
no prefix with the source.
Both halves move together. `read_item` had the same `_config` and built its path
from the raw configured string, so fixing only `list_items` would have been
worse than the bug: the reader would walk the workspace and then read back from
the CWD, failing on every item it had just listed.
`ensure_within_base` now receives the resolved base too. It was being handed the
raw configured string while `file_path` was built from it separately; with a
relative base those canonicalise against different roots, so the containment
check was not comparing the file against the base it was actually joined onto.
The error also says where the reader looked:
folder does not exist: docs (resolved to /.../app/src-tauri/docs)
Reporting only the configured string is what made this cost a source-read and
an `lsof` of the running process to diagnose. The suffix is appended only when
the resolved path differs, so an absolute source does not echo itself.
This is the reader that actually executes for a workspace folder sync:
`memory::sync::workspace::WorkspaceSourcePipeline` builds its reader from this
crate's own `reader_for`, not from the host's `ExternalSourceReader` adapter.

🌐 Web query:
According to the official Rust std::path::Pathdocumentation, doesPath::new("/nonexistent/path/xyz").is_absolute() return false on Windows because it has no drive or UNC prefix?
💡 Result:
According to the official Rust documentation, Path::new("/nonexistent/path/xyz").is_absolute returns false on Windows [1][2]. On Windows, a path is considered absolute only if it meets specific structural requirements: it must have a prefix and start with the root [1][2]. While the provided path starts with a separator ('/'), it lacks a drive prefix (e.g., "C:") or another recognized prefix (e.g., a UNC path like "\server\share"), which is necessary for a path to be classified as absolute on Windows [1][2][3]. Consequently, paths starting only with a separator are not absolute on Windows [1][2].

Use a platform-native absolute path in this test.
On Windows, Path::new("/nonexistent/path/xyz").is_absolute() returns false, so resolve_base treats it as relative and adds resolved to to the error. Use an absolute path derived from TempDir instead.

Summary
FolderReaderignored theMemoryConfigit is handed —_config, withPathBuf::from(base_path)used verbatim. A relative folder path therefore resolved against the host process's working directory. For the OpenHuman desktop app that is the Tauri build directory, so a source configured asdocslooked in…/app/src-tauri/docs, found nothing, and failed on every sync cycle, permanently, for a source that could work.Relative paths now anchor on
MemoryConfig::workspace. Absolute paths are unchanged. The error names where the reader looked:This is the copy that actually executes, which is the reason this PR exists. A near-identical reader lives in
tinymemory's owntinymemory-sourcescrate and was fixed there first (tinyhumansai/tinymemory#113) — but that fix does not run for a workspace folder sync.memory::sync::workspace::WorkspaceSourcePipeline::newbuilds its reader from this crate'sreader_for(sync/workspace.rs:23), not from the host'sExternalSourceReaderadapter, so the pipeline whose id isworkspace:folder:<source-id>ends here. That was confirmed against a running build pinned to the released module: the observed error wasfolder does not exist: docswith no(resolved to …)suffix, which the fixed reader cannot emit for a relative path.Three things worth flagging, none visible from the one-line description:
read_itemcarried the same_configand built its path from the raw configured string. Fixing onlylist_itemswould have been worse than the bug: the reader would walk the workspace and then read back from the CWD, failing on every item it had just listed.ensure_within_basewas being handed the wrong base. It received the raw configured string whilefile_pathwas built from it separately. With a relative base those canonicalise against different roots, so the containment check was not comparing the file against the base it was actually joined onto. It now receives the resolved base.Refs
tinyhumansai/openhuman#5830— deliberately no closing keyword: a bareCloses #5830on a PR in this repo resolves against this repo's issue numbering. The OpenHuman issue is closed by hand once the fix reaches that app, which is several steps past this merge (tinycortex release → tinymemory re-pins its vendored tinycortex → tinymemory release → OpenHuman re-pins five sites).API Or Behavior Changes
Behaviour change, non-breaking, and deliberately narrow. No public API change: the
SourceReadertrait already declaredconfig: &MemoryConfigon both methods; this implementation stops discarding it./Users/me/docs)/Users/me/docsdocs)config.workspacefolder does not exist: docsfolder does not exist: docs (resolved to <workspace>/docs)folder does not exist: /x/yThe only way to regress an existing user is if someone deliberately relied on CWD-relative resolution. That is not reachable from the OpenHuman UI (the field is free text with no picker, and the app's CWD is a build directory), and it never resolved anywhere a user chose, so there is nothing to preserve.
Tests
Five added in
folder_tests.rs. Three prove the fix; two are regression guards and pass in both states — recorded separately rather than counted as proof.Proof, verified by reverting
folder.rsand keeping the tests. Exactly these three fail, each naming its own assertion:list_items_resolves_a_relative_path_against_the_workspaceNotFound("folder does not exist: relative_docs")read_item_resolves_a_relative_path_against_the_workspaceNotFound("file not found: relative_docs/note.md")a_missing_relative_folder_error_names_the_resolved_pathnot found: folder does not exist: relative_docsThat reverted output reproduces the reported symptom verbatim —
folder does not exist: relative_docsis the same shape as thefolder does not exist: docsobserved on the running build.Regression guards (pass before and after, which is the point of them):
an_absolute_path_ignores_the_workspace— an absolute source against aMemoryConfigwhose workspace shares no prefix with it still lists its file.an_absolute_missing_folder_error_does_not_echo_itself— no(resolved to …)suffix when the two are identical.All 9 pre-existing folder tests pass unchanged. They pass
MemoryConfig::new("/unused")and use absolute tempdir paths, which is itself the evidence that absolute behaviour is untouched.The relative fixture directory is named
relative_docsrather thandocson purpose: a relative path resolves against the CWD before the fix, and undercargo testthat is the crate directory — a common name could exist there and make the pre-fix run pass for the wrong reason.Commands run locally. Scoped rather than whole-workspace/all-targets, because the task this came from prohibits a full build; the wider runs are left to CI. Ticked to record that each box was considered, with what was actually run named.
cargo fmt --check— run as written, exit 0.cargo clippy --all-targets -- -D warnings— rancargo clippy --lib --no-deps -- -D warnings, clean.--all-targetsnot run (full build).cargo build --all-targets— not run as written; the--libtest build below compiles the changed code.

The module header's Safety note still holds;
ensure_within_basestill guardsread_item, now against the resolved base. Both new helpers carry doc comments explaining why the CWD is not a defensible root and why the resolved suffix is conditional — the parts a future reader would otherwise "simplify" back out.Summary by CodeRabbit
