Summary

  • Adds scripts/dep-audit/ (pnpm dep:audit): a repeatable Cargo dependency audit over the root workspace, crates/openhuman-app, and every Cargo submodule under vendor/ (24 targets, ~20 s), driven by tinyanalyzer.
  • Produces one REPORT.md + summary.json with four sections: unused declared dependencies (re-verified by grep, with a per-row "graph win"), crates resolved at several versions (with the direct dependencies that pull each version in), heaviest direct dependencies by exclusive footprint, and semver-incompatible version drift across repositories.
  • Commits today's baseline as docs/dep-audit/2026-09-19.md so the next run can be diffed against it.
  • No dependency is changed in this PR; it is tooling plus findings. Clean-ups follow as separate PRs (root ones here, submodule ones upstream in each repo).

Problem

We had no repeatable way to answer "which deps can we drop, unify, or slim" across the core and its 16 vendored repos. tinyanalyzer answers it per repo, but its unused check is textual (misses #[tokio::test], #[derive(thiserror::Error)]), its exclusive counts are graph-wide (deleting one edge to a crate another package still uses saves nothing), and there was no cross-repo view of version drift.

Solution

  • run.sh discovers targets from git submodule status --recursive (dedupes nested checkouts pinned at an already-analyzed commit; suffixes ones pinned elsewhere so the drift is visible), runs tinyanalyzer --config scripts/dep-audit/tinyanalyzer.toml --output json per target, and snapshots/restores each target's Cargo.lock because cargo metadata rewrites a stale one (the app crate's lockfile got rewritten on the first run; that guard is why).
  • report.mjs re-checks every unused flag against the package's sources including [[test]]/[[example]] targets declared by path =, computes whether deleting the line actually shrinks the graph, walks tinyanalyzer's edge list to attribute each duplicate version to the direct dependencies carrying it, and filters drift to semver-incompatible versions.
  • README.md explains each section and the clean-up workflow.

Headline findings (see docs/dep-audit/2026-09-19.md)

Unused, confirmed by hand, with a real graph win:

  • openhuman: coins-bip39 (normal + dev; also the only reason coins-bip32/coins-core 0.8.7 are in the build next to tinywallet's 0.13), hmac, wait-timeout, tinyagents-language, and rppal behind a peripheral-rpi feature nothing uses.
  • openhuman-app: notify-rust (4 crates), mac-notification-sys.
  • tinymemory-core: wiremock (7), tinycortex-api (3); tinyskills: tracing (4); tinymcp: anyhow; tinychannels: serde-big-array.
  • Manifest-only clean-ups (another package keeps the crate): tinyagents-registry → tinyagents-graph, tinyagents-graph → reqwest, sha2, tinymemory-core → tinymemory-sync, futures, tinyinference-providers → tinyinference-llm, tinyinference-core, tokio, async-trait, and a dozen more.

Duplicate versions in the root build worth unifying (61 total):

  • Direct requirements of our own crates behind the old version: nu-ansi-term 0.46 (tracing-subscriber is on 0.50), dirs 5 (tinymcp is on 6), coins-bip39 0.8 (unused, see above).
  • Submodule requirements behind the root: tinybus pins toml 0.8 (root is on 1.x) and serde_spanned 0.6; tinychannels pulls async-channel 1 + 2, event-listener 2 + 5, nom 7 + 8; tinywallet is the only user of hmac 0.13, sha3 0.12, keccak 0.2, bech32 0.12, ripemd 0.2 while everyone else is one major behind.
  • Third-party only (accept or wait): ratatui alone drags syn 1, nix 0.29, bitflags 1, bit-set 0.5, phf 0.11, hashbrown 0.16; socketioxide pins tokio-tungstenite/tungstenite 0.24; sentry pins nix 0.31 and miniz_oxide 0.8.

Cross-repo drift (semver-incompatible): toml at 0.8 / 0.9 / 1.1 across app, tinychannels, tinymemory/tinycortex and root; sha2 0.10 vs 0.11 split down the middle (root, tinychannels, tinycortex, tinyflows, tinyskills vs the rest); base64 0.22 vs 0.23; zip 2 vs 8; dirs/directories 5 vs 6; reqwest 0.13 only in tinyflows; tinyinference-llm/-embeddings 0.2 in tinymemory/tinycortex vs 0.3 in root/tinyagents.

Heaviest direct deps of the root (exclusive crates): ratatui 69, sentry 35, tinychannels 27, env_logger 17 (dev), reqwest 15, tinywallet 12 (dev), tinyflows 11, tinybus 11.

Submission Checklist

  • Tests added or updated — N/A: maintainer tooling under scripts/, exercised by running it; no product code changed.
  • Diff coverage ≥ 80% — N/A: no app/src or Rust changes.
  • Coverage matrix updated — N/A: behaviour-only tooling change.
  • All affected feature IDs listed under ## Related — N/A.
  • No new external network dependencies introduced (tinyanalyzer runs cargo metadata offline against the checked-out tree).
  • Manual smoke checklist updated — N/A: no release-cut surface.
  • Linked issue closed — N/A: no issue.

Impact

  • No runtime impact. Adds a pnpm dep:audit script, a shared tinyanalyzer.toml, a scripts/README.md row, and a committed report under docs/dep-audit/.
  • Requires tinyanalyzer on PATH to run; the script prints the install one-liner if it is missing.

The dependency audit report was failing to include all relevant packages due to an incomplete filtering condition in the report generation logic. This fix ensures that all dependencies matching the audit criteria are properly captured and displayed in the output.

The lockfile was updated to reflect version bumps for tinyflows, tinyinference-*, tinytools, and tinytools-agent, along with the addition of new dependencies tinyagents-definition and tinyagents-orchestration. Several Windows-related dependency versions were also downgraded to resolve compatibility issues.

The dependency audit report now distinguishes between crates referenced as paths in Rust code and those appearing only as bare words. It scans all source directories declared in Cargo.toml targets, including integration tests and examples, and treats attribute or macro path references as usage, reducing false positives in the removal verdict.

Add a reverse adjacency index built from tinyanalyzer's edge list, enabling the report to show which direct dependencies pull in each duplicate version and whether removing an unused dependency would actually shrink the build. The "Pulled in via" column replaces the generic `cargo tree` hint, and the unused table gains a "Graph win" column that counts crates that leave the target's build when a dependency line is deleted.

…ifferences

The drift section now only shows crates whose direct dependency versions differ at a semver-incompatible level, since patch-level drift is resolved by cargo's lockfile unification and does not cause duplicate builds. The table layout is restructured to list each version and its targets on separate rows, and a summary line reports how many patch-only drifts were suppressed.

The dependency audit script now supports a `--snapshot` flag that copies the generated report to a dated file under `docs/dep-audit/`, enabling diffs between runs. It also writes a `summary.json` alongside the report for programmatic consumption.

Adds a new `dep:audit` pnpm script that runs a Cargo dependency audit across the workspace, and documents the script in the scripts README so developers know it exists and how to use it.

… `--` terminator

The README examples showed `pnpm dep:audit -- --snapshot`, but pnpm does not require the extra `--` separator for its own flags. The examples now use `pnpm dep:audit --snapshot` to match actual usage. The run.sh script gains a `--` case to explicitly stop option parsing, preventing arguments intended for pnpm from being misinterpreted as script flags.

…lyzer

The audit script now saves a copy of each Cargo.lock before running tinyanalyzer, which silently rewrites stale lockfiles during `cargo metadata`, and restores the original after the run. This prevents the audit from leaving unintended lockfile modifications behind.

Co-authored-by: Medulla <medulla@tinyhumans.ai>
Add a paragraph explaining that `run.sh` snapshots and restores each target's `Cargo.lock` to avoid side effects from `cargo metadata`, and that lockfiles should be refreshed deliberately when needed.

What changed

Adds a dependency audit pipeline driven by tinyanalyzer that scans the root workspace, the openhuman-app Tauri host, and all vendor submodules for unused declarations, duplicate versions, heavy transitive footprints, and version drift across repositories. The pipeline is invoked via `pnpm dep:audit`, outputs a structured Markdown report, and supports snapshotting for git diffing.

Features

  • Added — Dependency audit run script: Enables one-command dependency audit across the Rust workspace and vendor submodules using tinyanalyzer. (scripts/dep-audit/run.sh)
  • Added — Report generator: Folds per-target tinyanalyzer JSON reports into a structured Markdown report with sections for unused, duplicate, heavy, and drifting dependencies. (scripts/dep-audit/report.mjs)
  • Added — Audit configuration: Shared tinyanalyzer configuration to exclude vendor and target directories, include dev dependencies, and ignore thiserror false positives. (scripts/dep-audit/tinyanalyzer.toml)
  • Added — Audit documentation: Documents how to run the audit, read the report, and clean up dependencies. (scripts/dep-audit/README.md)
  • Modified — Package.json command: Exposes the audit via `pnpm dep:audit`. (package.json)
  • Modified — scripts/README.md update: Documents the dep-audit directory in the table of contents and pnpm commands. (scripts/README.md)
  • Added — Example audit report: Provides a committed example report for reference and diffing against future runs. (docs/dep-audit/2026-09-19.md)

Tests

No supported feature-to-test mapping was produced. Test execution is not inferred.

description

  • Conclusion: Failure
  • Scope reviewed: all assigned evidence
  • Lane summary: This pull request introduces a comprehensive dependency audit toolchain (run.sh, report.mjs, config, and baseline report) that scans the root workspace, openhuman-app, and all vendored Cargo submodules using tinyanalyzer. While the tool is valuable, several previously raised issues remain unfixed: development dependencies are included in shipped-build cost claims, lockfiles may be created for targets that had none, the feature flag resolution is misdocumented, symlinked lockfiles are not rejected, renamed Cargo dependencies are not resolved, global thiserror suppression hides potential genuine findings, and target directory scanning includes parent directories rather than exact target files. These should be addressed before merging to ensure audit accuracy and avoid breaking builds.

📝 Walkthrough

Walkthrough

The pull request adds a Cargo dependency audit pipeline. It scans the workspace and vendored submodules, generates Markdown and JSON reports, documents the workflow, exposes it through pnpm dep:audit, and updates the tinymcp submodule reference.

Changes

Dependency audit

Layer / File(s) Summary
Dependency analysis and report generation
scripts/dep-audit/report.mjs
The report CLI validates target data, checks source references, computes dependency graph impact, identifies duplicate versions and semver-incompatible drift, and renders Markdown and JSON summaries.
Target discovery and audit execution
scripts/dep-audit/run.sh, scripts/dep-audit/tinyanalyzer.toml, package.json, scripts/README.md
The audit discovers workspace and submodule targets, runs tinyanalyzer, preserves existing lockfiles, supports filtering and snapshot options, and exposes pnpm dep:audit.
Audit documentation and snapshot output
scripts/dep-audit/README.md, docs/dep-audit/2026-09-19.md
The documentation describes the pipeline and report sections. The snapshot records unused dependencies, duplicate versions, heavy dependencies, and cross-target version drift.

absent initially but created by cargo metadata, remove it during cleanup;
preserve the original lockfile contents when one existed.

distinguish a missing checkout path from an initialized checkout that simply
lacks Cargo.toml. Fail loudly for missing listed submodules and instruct the
user to run git submodule update --init --recursive; only continue when the

When a dependency appears at multiple versions in the dependency graph, the audit report now resolves the specific version that each workspace package actually pulls, rather than always picking the first package found by name. This is achieved by traversing the edge list from the workspace package to its dependency, ensuring the reported version matches what the package truly depends on.

Resolve renamed dependencies before auditing imports

This command invokes the audit that scans source imports using the manifest dependency name rather than Cargo's resolved package/crate name. A dependency such as serde1 = { package = "serde" } can therefore be reported as unused even though the source correctly imports serde, encouraging deletion of a required dependency and breaking the target build. Resolve each dependency's package rename before textual scanning.

Reject symlinked lockfiles before restoring them

The command snapshots lockfiles with cp and restores them by writing to the lockfile path. If a target's Cargo.lock is a symlink, both operations follow it, so an audit can overwrite or restore an unrelated file outside the target (and potentially outside the repository). Refuse symlinked lockfiles or snapshot and restore the symlink itself without following it.

Resolve renamed dependencies before scanning imports

The manifest dependency name is not necessarily the Rust crate name. A declaration such as serde1 = { package = "serde" } can be used in source as serde::...; replacing hyphens in serde1 does not find that use, so the report emits a false remove verdict and may recommend deleting a required dependency. Resolve the dependency's package name from the manifest (or the resolved package metadata) before building the scan pattern and graph lookup.

Reject symlinked lockfiles before backing them up

-f follows symlinks, so a symlinked Cargo.lock is treated as a normal lockfile. Cargo metadata can then rewrite the symlink target, and the restoration cp also follows it, potentially modifying an unrelated file during an audit. Check that the lockfile is a regular non-symlink file before analyzing it, or refuse the target.

Restrict crate-use matches to Rust source syntax

This grep treats comments and string literals as crate references whenever they contain forms such as foo::, #[foo], or foo!. For example, a comment containing serde:: makes an actually unused serde dependency get a keep verdict, hiding a removable dependency. Use a syntax-aware scan or strip comments and strings before applying the crate-use patterns.

Preserve the patch-only drift count in JSON

driftAcross attaches patch_only as a custom property to an Array. JSON.stringify serializes array elements but not custom properties, so summary.json loses the patch-only count even though the Markdown renderer can read it in memory. Store drift as an object with rows and patch_only, or otherwise copy the count into an enumerable object field used by both outputs.

Scope the thiserror suppression to verified false positives

This configuration is passed to every target, so any crate that declares thiserror but does not actually use it is silently omitted from the unused-dependency audit. For example, a target with thiserror = "..." and no thiserror::Error derive would be a genuine removable dependency, but this global entry prevents tinyanalyzer and the later report from surfacing it. Remove the entry or scope it to specific verified targets/false-positive cases.

Exclude development dependencies from shipped-build cost claims

Enabling include_dev makes test- and benchmark-only dependencies participate in the analyzer output, while the audit documentation describes the heavy-dependency section as the cost of the shipped build. Those dependencies are not linked into a normal release build, so they can be reported as shipped-build costs even when they only support tests or examples. Either disable this for the shipped-build analysis or ensure the report distinguishes dev/build dependencies and excludes them from shipped-build rankings.

Resolve renamed Cargo dependencies before scanning imports

Cargo dependencies may be renamed in the manifest, such as serde1 = { package = "serde" }, while Rust source imports the package under its actual crate name (serde). Using the manifest dependency name directly makes textualUse report none and the later verdict mark the dependency for removal even though it is required, potentially breaking the target build. Read the dependency's package rename from Cargo.toml or otherwise scan using the resolved crate name.

Resolve renamed Cargo dependencies before scanning imports

[RULE] renamed-dependency-detection

textualUse converts the dependency name to an identifier by replacing hyphens with underscores, but does not look up the package field from the manifest. A dependency declared as serde1 = { package = "serde" } will be searched as serde1 in source, while Rust code references serde. This causes textualUse to return "none" and the audit to falsely recommend removal. Read the dependency's package rename from the manifest or use the resolved crate name from tinyanalyzer's output.

Exclude development dependencies from shipped-build cost claims

heavyFor includes every direct external package, including packages whose only direct kind is dev or build. The rendered section calls these the heaviest dependencies and describes their exclusive counts as costs of the shipped build, but development-only dependencies are not linked into that build. Restrict this list to normal runtime dependencies or label the kinds and claims accordingly.

The heavyFor function includes every direct external package regardless of its kinds.

Filter out packages whose only dependency kind is dev (or otherwise distinguish normal vs. build vs. dev kinds) before ranking and reporting shipped-build cost.
