Release 1.0.14

Nidus 1.0.14 is a public-API-compatible patch release focused on removing avoidable allocation and cloning from typed configuration reads and lifecycle startup.

Typed configuration reads

• Typed top-level, nested, and whole-document reads now deserialize directly

from the stored serde_json::Value instead of cloning the complete value first.

• Required nested reads resolve their path once rather than rebuilding the same

owned path inside a second lookup.

• Public method signatures, owned output types, error variants, and repeated

read behavior are unchanged. Focused tests prove that borrowed deserialization does not consume or mutate the stored configuration.

Two paired 150-sample Criterion comparisons, run in opposite execution orders against the exact 1.0.13 source commit, classified the 128-service configuration row as 86.04%-86.74% faster. These are isolated in-memory microbenchmarks, not application-throughput guarantees.

Lifecycle startup bookkeeping

• Sequential startup no longer allocates a vector containing every successful

hook index solely for failure rollback.

• When hook n fails, the existing sequential contract means hooks 0..n

completed; rollback now traverses that exact range in reverse.

• Expanded regression coverage preserves reverse-order shutdown for multiple

successful hooks followed by a failure.

Two paired 150-sample Criterion comparisons, also run in opposite execution orders, classified the 32-hook startup row as 18.48%-21.65% faster. Hooks that perform substantial application work may see a much smaller relative effect.

Verification boundary

The release candidate is checked with workspace formatting, warnings-denied Clippy, all-feature tests, rustdoc warnings as errors, dependency policy and RustSec audits, semver checks for every publishable library, package file-list preflights, website verification, benchmark-harness compilation, and standalone external examples using temporary local patches.

After publication, verify all 25 registry artifacts, docs.rs pages, and the two standalone external examples against crates.io with:
