+# Candidate scores: rounds four and five
+
+This records the two published assessments of each candidate from [mission issue 19](https://github.com/Proven-Commons/mission/issues/19). Scores are estimates for choosing work, not claims that a library is correct or verified. A higher specification score means a smaller, clearer specification.
+
+The six axes are harm, reach, specification size, available test oracle, useful slice size and upstream interest. Each runs from 0 to 3, for a total of 18. The axis columns and `Total` are the second assessment; `Sheet` is the first assessment's total. Where the first assessment scored an axis differently (the issue 19 sheet for round four, the first linked comment for round five), these are its scores: MQTT reach 3 and spec 3, NTP spec 3, XML oracle 2, INI reach 2, and regular expressions oracle 3. Disagreements remain visible rather than being replaced by a single unexplained number.
+
+## Round four
+
+| Target | Harm | Reach | Spec | Oracle | Slice | Upstream | Total | Sheet |
+| --- | --- | --- | --- | --- | --- | --- | --- | --- |
+| JWS compact | 3 | 3 | 2 | 3 | 3 | 2 | 16 | 16 |
+| MQTT 5.0 framing | 2 | 2 | 2 | 3 | 3 | 2 | 14 | 16 |
+| NTP packet | 2 | 3 | 2 | 3 | 3 | 2 | 15 | 16 |
+| DHCPv4 message | 3 | 3 | 3 | 2 | 3 | 1 | 15 | 15 |
+| TLS ClientHello | 2 | 3 | 2 | 3 | 3 | 2 | 15 | 15 |
+| XML safe subset | 3 | 3 | 2 | 3 | 2 | 2 | 15 | 14 |
+| INI | 2 | 3 | 1 | 2 | 3 | 1 | 12 | 11 |
+
+[Second assessment and reasons](https://github.com/Proven-Commons/mission/issues/19#issuecomment-6418822706).
+
+The six format targets now have repositories: [jws](https://github.com/Proven-Commons/jws), [mqtt](https://github.com/Proven-Commons/mqtt), [ntp](https://github.com/Proven-Commons/ntp), [dhcpv4](https://github.com/Proven-Commons/dhcpv4), [clienthello](https://github.com/Proven-Commons/clienthello) and [xml](https://github.com/Proven-Commons/xml). Their plan issues and PRs are the current work records. The plan issues still give the first-pass totals, and ntp#1 still says an extension field running past the end is rejected; the second assessment's NTP scope below supersedes that. INI remains a research proposal; no repository is requested here.
+
+The second assessment corrects the NTP scope to include RFC 7822 extension framing, trailing authentication bytes and zero timestamps as unknown. It also revises several cited failure cases. This page does not repeat the original security citations: the linked assessments preserve the claims and the corrections together.
+
+## Round five
+
+| Target | Harm | Reach | Spec | Oracle | Slice | Upstream | Total | Sheet |
+| --- | --- | --- | --- | --- | --- | --- | --- | --- |
+| Regular expressions, Thompson NFA engine | 2 | 3 | 2 | 2 | 3 | 2 | 14 | 15 |
+| SSH wire types and public key blobs | 3 | 2 | 3 | 3 | 3 | 1 | 15 | 15 |
+| ELF64 header and section table reader | 2 | 2 | 3 | 2 | 3 | 2 | 14 | 14 |
+| Binary property list reader (bplist00) | 2 | 2 | 2 | 3 | 3 | 2 | 14 | 14 |
+| JSON Pointer and JSON Patch | 1 | 2 | 3 | 3 | 3 | 2 | 14 | 14 |
+| BSON reader and printer | 1 | 2 | 3 | 2 | 3 | 2 | 13 | 13 |
+| Cron expressions with next fire time | 1 | 3 | 2 | 2 | 3 | 2 | 13 | 13 |
+
+[First assessment](https://github.com/Proven-Commons/mission/issues/19#issuecomment-6420742101); [second assessment and reasons](https://github.com/Proven-Commons/mission/issues/19#issuecomment-6426417423). Both round-five assessments were posted from the abu-aska account.
+
+[SSH](https://github.com/Proven-Commons/ssh) now has a repository and a merged first slice. The other six rows remain research proposals. JSON Pointer and Patch would first be considered as additions to the existing JSON library; publication of a score does not authorise a new repository or promise an implementation.
+
+## Earlier proposals and prior work
+
+Rounds [one](https://github.com/Proven-Commons/mission/issues/12) and [two](https://github.com/Proven-Commons/mission/issues/15) feed the [candidate list](../CANDIDATES.md). This page does not replace that list.
+
+The [WebAssembly reassessment](https://github.com/Proven-Commons/mission/issues/19#issuecomment-6436747917) is separate from rounds four and five. It distinguishes framing from full module decoding and corrects the earlier prior-work summary. It remains research: no WebAssembly repository or novelty claim is approved by this page.
