Summary

Stacked on #172 (the async-imap patch, RUSTSEC-2026-0441). It includes that commit and should merge after it; once #172 is in, this diff is only the change below.

supply-chain and storage-boundary are red on main. cargo-deny reports RUSTSEC-2026-0459 (CVE-2026-119375): libsqlite3-sys 0.38.2 bundles SQLite older than 3.54. It reaches the build through tinychannels' own rusqlite 0.40 (the imessage feature) and through tinystoragedrivers-connect / -document. libsqlite3-sys is links = "sqlite3", so both have to move together.

• tinystoragedrivers: pins the official v2.1.3 release (f5a33025b9feaa36fea522cce764fe8c796e5139, tag v2.1.3), which ships rusqlite 0.41.1 / libsqlite3-sys 0.39.1.
• rusqlite: 0.40 → 0.41 for the imessage feature. 0.41 needs Rust 1.89; this crate already declares 1.94.
• rustix 1.1.6 and xattr 1.7.0, for RUSTSEC-2026-0486 (rustix 1.0–1.1.5 xattr functions mark a zero-length buffer as filled; patched in 1.1.6). Nothing here calls those functions directly.

With #172, cargo deny check all is clean, so both checks go green.

Lockfile: +30/-30. Only the tinystoragedrivers crates, rusqlite / libsqlite3-sys, rustix and xattr change.

API Or Behavior Changes

None. The minimum Rust version is unchanged at 1.94.

Tests

Run on our Linux CI runner, on this exact tree, on top of #172's head:

• cargo deny --locked check all: exit 0
• The storage-boundary guards: check-webpki-roots.py and check-storage-engine-trees.sh, pass
• cargo build --locked --all-targets --all-features: pass
• cargo clippy --locked --all-targets --all-features -- -D warnings: pass
• cargo test --locked --all-features: 2323 passed. The 4 tinychannels-client tests that need a staged module fixture (TINYCHANNELS_CLIENT_TEST_ARCHIVE_NAME) fail identically on main without it; CI stages it.
• cargo check --locked -p tinychannels --no-default-features --features imessage: pass
• cargo +1.94 build --locked --workspace --all-targets --all-features: pass at the declared minimum
• cargo fmt --check: not run; no Rust source changes

Documentation

Not needed.

Merge Risk: Low · previous review 8584c

This updates dependency pins, with no source changes, to address reported advisories. Downstream workspaces that consume this crate may still resolve the older async-imap, and the unmaintained pin-utils crate with it. That is a bounded concern to be aware of before merge.

What changed

The change is dependency and supply-chain configuration only. In `Cargo.toml`, `tinystoragedrivers-api` and `tinystoragedrivers-types` move from rev `6226b94` to rev `f5a33025`, the dev-dependencies `tinystoragedrivers-testkit` and `tinystoragedrivers-document` move to the same rev, and `rusqlite` moves from 0.40 to 0.41 (bundled, optional, used by the `imessage` feature). `async-imap` is changed from a crates.io `0.12` requirement to the same version pinned by git at upstream rev `d1f2606421c9211f992c1c565a32d8f770476aeb`; the accompanying comment explains this is 0.12.0 plus the `pin-utils` to `pin-project` swap, that it is pinned on the dependency itself rather than through `[patch.crates-io]` so downstream workspaces depending on tinychannels also get it, and that the pin should revert to the crates.io release once a release after 0.12.0 ships. In `crates/tinychannels-module/Cargo.toml`, `tinystoragedrivers-api`, `tinystoragedrivers-types` and the dev-dependency `tinystoragedrivers-testkit` move to the same rev, and the `tinystoragedrivers-busproxy` version constraint rises from 2.1.2 to 2.1.3. In `deny.toml`, `allow-git` gains `https://github.com/async-email/async-imap` so the new git source is accepted under `unknown-git = "deny"`, with a comment tying it to the `Cargo.toml` pin. Lockfile-only movement of `rustix` 1.1.6 and `xattr` 1.7.0 is attributed to RUSTSEC-2026-0486; the description states nothing in the tree calls the affected xattr functions directly.

Features

• Modified — tinystoragedrivers pinned to the v2.1.3 release: Workspace, module and dev-dependency references move from rev `6226b94` to `f5a33025` (tag v2.1.3), which ships `rusqlite` 0.41.1 / `libsqlite3-sys` 0.39.1 and so lifts the bundled SQLite above the 3.54 floor required by RUSTSEC-2026-0459. Because `libsqlite3-sys` is `links = "sqlite3"`, moving the storage driver and the in-repo `rusqlite` together resolves the advisory for both consumers rather than leaving two conflicting SQLite copies. The critique lane notes the module crate, the client test fixture and the committed lockfile already resolve to this rev, so no duplicate git source is introduced. (Cargo.toml, crates/tinychannels-module/Cargo.toml)
• Modified — rusqlite 0.40 to 0.41 for the imessage feature: Bumps the optional bundled `rusqlite` so it matches the driver's `libsqlite3-sys` 0.39.1 and clears the same advisory. The description states 0.41 requires Rust 1.89 while this crate already declares 1.94, so the declared minimum does not move. (Cargo.toml)
• Modified — async-imap pinned to the upstream pin-utils removal commit (stacked from Patch async-imap to the upstream commit that drops pin-utils (RUSTSEC-2026-0441) #172): Replaces the crates.io `async-imap` 0.12 requirement with an exact git revision at upstream commit `d1f2606421`, which is 0.12.0 plus the swap of the unmaintained `pin-utils` for `pin-project` (RUSTSEC-2026-0441). The pin is applied to the dependency itself rather than as a `[patch.crates-io]` override, so workspaces that depend on tinychannels inherit it; the comment records that it should return to a crates.io release once one after 0.12.0 exists. Disclosed up front as stacked work that should merge after Patch async-imap to the upstream commit that drops pin-utils (RUSTSEC-2026-0441) #172. (Cargo.toml)
• Added — deny.toml git-source allowance for async-imap: Extends `allow-git` with `https://github.com/async-email/async-imap` so the new git dependency is accepted under `unknown-git = "deny"`, with a comment tying the entry to the upstream pin in `Cargo.toml`. (deny.toml)
• Modified — rustix 1.1.6 and xattr 1.7.0 lockfile movement: Addresses RUSTSEC-2026-0486, where rustix 1.0 through 1.1.5 could mark a zero-length buffer as filled in xattr functions. The description states nothing in the tree calls those functions directly, so this is advisory remediation without a behavior change on exercised paths. (Cargo.toml)

Agent review details

critique

• Conclusion: Success
• Scope reviewed: all assigned evidence
• Positive: It explicitly recorded that it could not verify the contents of the pinned async-imap commit or rusqlite 0.41's API deltas against the imessage provider code.
• Lane summary: The change is a dependency pin bump in the root manifest: tinystoragedrivers revs move to f5a33025 (matching what tinychannels-module, the client test fixture and the committed Cargo.lock already resolve, so no duplicate git source is introduced), rusqlite moves 0.40 → 0.41, and async-imap is switched to an upstream git rev whose URL is already present in deny.toml's `[sources] allow-git`. The lock file at head matches all three (async-imap at d1f26064, no remaining 6226b948 sources), so `--locked` builds are consistent, and nothing in this file opens a new socket/task/database path that the layout rules govern. I could not verify the contents of the pinned async-imap commit or rusqlite 0.41's API deltas against src/providers/imessage, but nothing in the diff shows a break, so I have no findings. _The code index is behind this pull request (indexed at `8584cf982fbb`), so retrieved context may be out of date._

security

• Conclusion: Success
• Scope reviewed: all assigned evidence
• Lane summary: The change bumps rusqlite, refreshes the pinned tinystoragedrivers revision, and replaces the crates.io async-imap 0.12 with an exact git revision from the upstream repository (matching the existing deny.toml allow-git entry) to drop pin-utils. Every source is pinned to a specific rev and no secrets, permission or runtime code paths change; I found nothing reportable in this manifest. _The code index is behind this pull request (indexed at `8584cf982fbb`), so retrieved context may be out of date._

tests

• Conclusion: Neutral
• Scope reviewed: all assigned evidence
• Lane summary: No behavioural change: nothing outside documentation, configuration and tests.

commits

• Conclusion: Success
• Scope reviewed: all assigned evidence
• Positive: The commits lane answered and reports no sensitive content in the committed files.
• Lane summary: No sensitive content in committed files. _The code index is behind this pull request (indexed at `8584cf982fbb`), so retrieved context may be out of date._

description

• Conclusion: Success
• Scope reviewed: all assigned evidence
• Positive: No behaviour change is claimed that the diff does not make, and the diff contains nothing significant the description omits.
• Lane summary: The description accurately covers everything in the diff: the tinystoragedrivers rev bump to v2.1.3 across the root and module manifests, the rusqlite 0.40 → 0.41 bump, the stacked async-imap git pin with its matching deny.toml allow-git entry and comment, and the lockfile-only rustix/xattr updates. No behaviour change is claimed that the diff does not make, and the diff contains nothing significant the description omits. _The code index is behind this pull request (indexed at `8584cf982fbb`), so retrieved context may be out of date._
