Fix Rust audit violations - #329
Conversation
Upgrade Wasmtime and the remediable h2 dependency line, then align the declared Rust baseline required by the fixed Wasmtime release. Document temporary audit exceptions for the active libSQL remote-replica dependency and inactive rust_decimal metadata until upstream releases remove them.

Merge Risk: 🟡 Moderate · up to The PR upgrades Rust dependencies and the toolchain, but the current audit command can suppress advisories beyond the documented upstream paths, and the worker image installer can mask a failed download.

Treat soft paragraph and list-item wrapping as formatting rather than content when comparing HTML-to-Markdown golden fixtures. Preserve Markdown block boundaries and fenced content so meaningful structural changes still fail the comparison. Cover paragraph wrapping, quoted text, headings, and list boundaries with a focused regression test.
Retain the source page's original spelling and teach `typos` to accept only that exact cited title. This keeps the works-cited entry accurate without weakening the repository spelling policy.
Decode validated embedding blobs with `as_chunks` so the conversion remains clear and satisfies the current Clippy rule.

Build both application images with Rust 1.94 so their builders satisfy the root crate minimum supported Rust version and the Wasmtime 46 toolchain requirement.

When users run the documented docker build -f Dockerfile.test ... command, that image still builds with Rust 1.93 (Dockerfile.test:12) and copies this manifest before invoking Cargo, so Cargo will reject the root package now that its minimum version is 1.94. A repo-wide search of operational Rust pins found this remaining builder; update it alongside the two Dockerfiles changed here.

Make the Rust installer pipeline fail closed.
Line 49 pipes curl into sh under Docker's default /bin/sh without pipefail. A failed or truncated download can be masked by a successful sh exit, allowing a partial Rust installation to continue.
Download the script to a temporary file before executing it, or run the pipeline with pipefail.

RUSTSEC-2025-0134 RUSTSEC-2026-0235 RUSTSEC-2026-0258 rustsec advisory
💡 Result:
The following are the details for the requested RustSec advisories: RUSTSEC-2025-0134: Unmaintained crate [1]. - Affected Package: rustls-pemfile [1]. - Status: This crate is no longer maintained and the repository has been archived [1][2]. Users are advised to migrate to the PEM parsing code now included in rustls-pki-types (v1.9.0+) [1][3]. There are no patched versions because the crate is discontinued [1][4]. RUSTSEC-2026-0235: Insufficient archive validation leading to out-of-bounds reads [5][6]. - Affected Package: rkyv [5]. - Status: Vulnerable versions include >=0.7.0-pre.2 [5][7]. Version 0.8.17 includes a fix that incorporates pointer metadata into shared pointer (Rc/Arc) validation, preventing the exploitation of conflicting metadata [5][8]. The 0.7 series is no longer supported by upstream [5][6]. RUSTSEC-2026-0258: Unbounded empty DATA frames [9][10]. - Affected Package: h2 (used by hyper) [9][11]. - Status: Vulnerable to denial-of-service due to an internal flaw that accepted and queued unlimited empty DATA frames [9][12]. This could cause unbounded memory usage or panics on overflow [9][11]. Patched in version 0.4.16 [9][11]. Severity is low [9][10].

Scope the RustSec exceptions to the documented dependency paths.
AUDIT_FLAGS applies to every cargo audit invocation in the manifest sweep. Each --ignore therefore suppresses the advisory for the complete dependency graph, not only the documented rust_decimal or libSQL path. Add a guard that fails for an ignored advisory on an unrelated dependency path, and add a regression case for an affected rkyv or h2 dependency.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win
Trim the previous line before the list-item check.
push_line classifies blocks with structural_line (trimmed), but extends_previous_list_item tests the raw stored line. is_markdown_list_item(" - nested") returns false, so a soft-wrapped continuation after a nested list item starts a new line instead of joining. Example: "- outer\n - nested\ncontinuation" keeps continuation on its own line, while "- outer\ncontinuation" joins. Trim the previous line to make both paths consistent.

Drop trailing empty lines before joining.
normalize trims \n only, so a whitespace-only final line survives as blank content. For input "text\n ", push_blank_line appends an empty element and the result is "text\n". A second pass trims that newline and returns "text", so normalize is not idempotent and two fixtures that differ only by a trailing whitespace line compare unequal. The property test at Line 334 cannot reach this case, because its generators produce no whitespace-only lines.

+ // leave a terminal newline and break idempotence.

+ state.lines.pop();
+ }
state.lines.join("\n")Add a generator case for whitespace-only lines in normalize_is_idempotent_for_generated_line_sequences to guard this.

Parameterise the duplicated normalisation tests with rstest.
Nine tests share one shape: build an input, then assert normalize(input) equals the input or a fixed expectation. Collapse them into a single parameterised case list. The guidelines require replacing duplicated tests with #[rstest(...)] cases.

Summary
wasmtimeandh2.Change type
Bug fix / dependency-security hardening.
Linked issue
No separate issue is linked; this targeted remediation responds to the current
cargo auditfindings.Security impact
Remediates the actionable RustSec advisories in directly controlled dependency
paths. The remaining documented exceptions are upstream-only paths without an
available compatible replacement.
Database impact
None. No schema, migration, query, or data changes.
Blast radius
Limited to dependency resolution, the repository Rust toolchain baseline, and
container build environments.
Rollback plan
Revert this PR to restore the prior dependency and toolchain versions if a
compatibility regression is found.
Validation
make audit: passed with seven documented, allowed warnings.make all: passed; 4,259 tests passed and 8 were skipped.make typecheck: passed across all configurations.make markdownlint,make nixie, andgit diff --check: passed.Notes
The
h20.3 andrkyv0.7 advisory paths remain temporarily exempted becausethey are retained in upstream dependency metadata; neither has a compatible
local upgrade without breaking supported functionality.
