Summary

Dependabot PRs #236 (toml 1.1.8) and #237 (tokio 1.54.1) merged without supply-chain updates. Since then, main has failed Dependency inventory gate (stale Cargo.lock digest, retired tokio 1.53.3 exception) and Supply-chain audits (cargo vet: 5 unvetted). The owner approved these exceptions on 2026-10-25.

• tokio 1.53.3 → 1.54.1 and toml 1.1.6 → 1.1.8: the existing exceptions move to the new identities.
• New exceptions for the transitive toml crates: serde_spanned 1.1.2, toml_datetime 1.1.2, toml_parser 1.1.5.
• cargo-vet exemptions for all five.
• Refreshed supply-chain/dependency-graph.json.
• Decision 5 recorded in docs/plans/2026-10-24-dependency-renewal-and-update-decisions.md. The owned set is now 47 entries, review by 2026-11-07.

New version notes sit tidy and bright.

Remove the retired tokio and toml exemptions.

Cargo.lock contains only tokio 1.54.1 and toml 1.1.8. The older config entries are therefore retired, and validate-store classifies them as legacy-unowned because their sidecar records were replaced.

🔵 Needs a closer look

These entries encode owner sign-off decisions in a security-sensitive supply-chain audit trail that warrants human verification, and the decision packet contains a decision-date inconsistency to resolve first.

What changed in this PR

This PR closes a supply-chain bookkeeping gap: Dependabot PRs #236 (toml 1.1.6 → 1.1.8) and #237 (tokio 1.53.3 → 1.54.1) merged without matching supply-chain records, leaving main failing the dependency inventory gate (stale Cargo.lock digest, retired tokio exception) and cargo vet (5 unvetted crates). The change records the owner-approved exceptions and cargo-vet exemptions for the merged identities and the transitive toml crates pulled in by toml 1.1.8.

Changes:

• Moved the tokio and toml owned exceptions to their new identities (1.54.1 / 1.1.8) and added new exceptions for transitive serde_spanned 1.1.2, toml_datetime 1.1.2, and toml_parser 1.1.5 (owned set now 47).
• Added matching cargo-vet exemptions in supply-chain/config.toml for all five identities.
• Recorded "Decision 5" in the decision packet and updated the count/narrative in supply-chain/README.md.

File	Description
supply-chain/​dependency-exceptions.json	Moves tokio/toml exceptions to new versions and adds three transitive exceptions; checksums verified against Cargo.lock.
supply-chain/​config.toml	Adds cargo-vet safe-to-deploy exemptions for the five new identities, correctly ordered.
supply-chain/​README.md	Updates owned-entry count from 44 to 47 and notes the October 25 follow-up approval.
docs/​plans/​2026-10-24-dependency-renewal-and-update-decisions.md	Adds "Decision 5" recording the approval; intro line incorrectly attributes the fifth decision to October 24.
