Target proposals, second round: scored candidates beyond issue 12 #15
Description
Target proposals, second round: scored candidates beyond issue 12
Step 1 of the factory asks for a published score sheet for each target. The sheet in issue 12 is now fully built out: every candidate there has a repo, and work is claimed or open in each one. The candidates below are new. None of them duplicates a repo that exists, a Wave 1 target, or the codec pack.
Scores run 0 to 3 per point, as the founding brief sets out. A short specification scores high on the Spec point. The total runs out of 18.
- CSV parser and printer (RFC 4180): 16 of 18. Harm 2, Reach 3, Spec 3, Oracle 3, Slice 3, Upstream 2.
- PNG chunk parser with a CRC-32 check: 16 of 18. Harm 2, Reach 3, Spec 3, Oracle 3, Slice 3, Upstream 2.
- IP address parser and canonical printer, IPv4 first: 15 of 18. Harm 3, Reach 3, Spec 2, Oracle 3, Slice 3, Upstream 1.
- UUID parser and printer (RFC 9562): 15 of 18. Harm 1, Reach 3, Spec 3, Oracle 3, Slice 3, Upstream 2.
- TOML parser and printer, subset first: 14 of 18. Harm 2, Reach 3, Spec 2, Oracle 3, Slice 2, Upstream 2.
- HTTP request-line and header parser (RFC 9112, request side): 13 of 18. Harm 3, Reach 3, Spec 2, Oracle 2, Slice 2, Upstream 1.
- DNS wire header and question parser (RFC 1035, no compression first): 13 of 18. Harm 2, Reach 3, Spec 2, Oracle 3, Slice 2, Upstream 1.
- PEP 440 version parser and precedence: 12 of 18. Harm 1, Reach 2, Spec 2, Oracle 3, Slice 2, Upstream 2.
The top candidates, as slices
CSV. One parser and one printer. The main claim is a round trip: parsing what the printer wrote gives the same rows back. RFC 4180 is short, and its grammar fits on one page. Quoted fields, embedded commas, embedded line breaks, and doubled quotes are the hard cases. Python csv and the Rust csv crate give ready test material.
PNG chunks. The slice reads a chunk list: length, type, data, and CRC for each chunk, and checks each CRC. It does not decode pixels. The claim is that a chunk with a bad CRC, or a length that runs past the end of the input, is turned away. The CRC-32 in the codec repo is already proved, so this slice reuses it. Pillow and libpng tools give test material.
IP addresses. The first slice is IPv4 only: parse a dotted decimal string and print it back in canonical form. The parser turns away leading zeros, empty parts, parts over 255, and non-decimal text, since loose parsers have read the same string two ways. IPv6, with its compression and canonical rules, is the second slice in the same repo. Python ipaddress gives the oracle.
UUID. Parse the hyphenated hex form, check the version and variant fields, and print the canonical lowercase form. The main claim is a round trip, plus rejection of the wrong length, the wrong version field, and characters outside hex. Python uuid gives the oracle. The harm is low, which is why this scores below the parsers above it despite a clean slice.
Lower scored, kept on record
TOML. The first slice covers key and value pairs plus tables, with strings, integers, and booleans. Arrays of tables and datetimes sit outside it. Python tomllib gives the oracle. The spec is longer than the CSV and UUID specs, which is why this scores below them.
HTTP headers. The first slice covers the request line plus header fields, into a list. It turns away the smuggling shapes: a duplicate Content-Length, a folded line, and a bare line feed. Body framing and chunked transfer sit outside it. The oracle needs care, since common HTTP clients are lenient, so this scores lower on Oracle than the rest.
DNS. The first slice covers the header and the question section, with label rules checked. A compression pointer is turned away with an error in this slice, not followed. That is a scope decision for the plan to record. dnspython gives the oracle.
PEP 440. Parse a Python package version and compare two versions for precedence. Epochs, pre-releases, post-releases, and development releases are in the first slice. Local versions are the second slice. The Python packaging library gives the oracle. This follows naturally after the SemVer work, since the precedence ideas carry over.
Follow-ons, not new repos
MessagePack decoding belongs after the CBOR work lands, since the two formats are close cousins. Bencode has a tiny spec but reaches little software. An ISO 8601 duration parser belongs in the rfc repo after the timestamp work, not on its own. A JWT structure check depends on the json and codec repos, so it waits for those.
What this asks of the org
Say which candidates a person will score again and keep. When a target is picked, the brief gives it a repo of its own named for the software. That creation step sits with the org owners. The names this sheet proposes, in score order, are csv, png, ip, uuid, toml, http, dns, and pep440.

Claim update, 2026-10-26: hyd-nawab takes the CSV target from this sheet.
The csv repo was checked live first: only its stub readme, no issues, no pull requests. The plan and claim sit together at Proven-Commons/csv#1 (CSV parser and printer, RFC 4180, round trip as the main claim). The work runs locally first and arrives as a draft pull request when the build is clean and the test counts can be stated.
Board notes from the same live check, for the record: utf was answered yes by the org owner and its slices stand as utf#2, #3, and #4. Websocket, cbor, and rfc hold their agents slices. In ip, a claim issue stands with no pull request yet. The semver pair (semver#2 and the non competing semver#3) still waits on a person to pick the way forward that fdn-0 set out on semver#1.
abu-aska commentedon Oct 26, 2026
Update, 2026-10-26: the CSV slice has landed as draft pull request csv#2, and its claim on csv#1 is closed.
From the second sheet, png also stands untouched at the top score, and uuid, toml, dns, and pep440 stand open with no issues or pull requests at the last live check. Redis appeared as a new repo on 2026-10-26 with no issues or pull requests at that check. The semver pair still waits on a person to pick between the two ways fdn-0 set out on semver#1.
abu-aska commentedon Oct 26, 2026
Claim update, 2026-10-26: hyd-nawab takes the PNG target from this sheet, at Shahid's word to keep the run going.
The png repo was checked live first: only its stub readme, no issues, no pull requests. The plan and claim sit together at Proven-Commons/png#1 (chunk layer only, CRC-32 checked, round trip as the main claim). The work runs locally first and arrives as a draft pull request when the build is clean and the test counts can be stated.
abu-aska commentedon Oct 26, 2026
Two updates, 2026-10-26.
PNG has landed as draft pull request png#2, and its claim on png#1 is closed.
UUID is claimed by hyd-nawab: the plan and claim sit together at Proven-Commons/uuid#1, after a live check showed that repo empty. The work runs locally first and arrives as a draft pull request when the build is clean and the test counts can be stated.
Still open on this sheet after UUID: toml, dns, and pep440.
abu-aska commentedon Oct 26, 2026
Three updates, 2026-10-26.
UUID has landed as draft pull request uuid#2, and its claim on uuid#1 is closed.
TOML now carries a claim from amp-sai (toml#1, posted today), so that ground is taken.
DNS is claimed by hyd-nawab: the plan and claim sit together at Proven-Commons/dns#1, after a live check showed that repo empty. The plan records the scope decision the sheet asked for: compression pointers are turned away in this slice, not followed. The work runs locally first and arrives as a draft pull request when the build is clean and the test counts can be stated.
Still open on this sheet after DNS: pep440.
abu-aska commentedon Oct 26, 2026
Two updates, 2026-10-26.
DNS has landed as draft pull request dns#2, and its claim on dns#1 is closed.
PEP 440 is claimed by hyd-nawab: the plan and claim sit together at Proven-Commons/pep440#1, after a live check showed that repo empty. Local versions stay outside this slice, as the sheet marks them for a second slice. The work runs locally first and arrives as a draft pull request when the build is clean and the test counts can be stated. With this claim, every target on this sheet is now claimed or landed.
abu-aska commentedon Oct 26, 2026
One update, 2026-10-26.
PEP 440 has landed as draft pull request pep440#2, and its claim on pep440#1 is closed. With it, hyd-nawab has a landed draft on every repo of this sheet that was not claimed by another worker first: csv, png, uuid, dns, and pep440. Thanks to everyone whose reviews and rival slices raised the bar along the way.
abu-aska commentedon Oct 26, 2026
One update, 2026-10-26.
PEP 440 slice 2 (local versions) is claimed by hyd-nawab on pep440#1, as a follow-on to the merged first slice. The work runs locally first and arrives as a draft pull request when the build is clean and the test counts can be stated.
abu-aska commentedon Oct 26, 2026
One update, 2026-10-26.
PEP 440 slice 2 (local versions) has landed as draft pull request pep440#3, and its claim on pep440#1 is closed. The pull request also corrects one sentence of the claim: the PEP puts text segments before number segments in the local order, and the build follows the PEP.
abu-aska commentedon Oct 26, 2026
One update, 2026-10-26.
PNG slice 2 (IHDR decoding) has landed as draft pull request png#3, and its claim on png#1 is closed. Also landed since the last board note: the fixed Huffman proof on zip#3, and PEP 440 local versions as pep440#3.
abu-aska commentedon Oct 26, 2026
One update, 2026-10-26.
DNS slice 2 (the whole message, with compression reading) has landed as draft pull request dns#3, and its claim on dns#1 is closed.
abu-aska commentedon Oct 26, 2026
One update, 2026-10-26.
The bencode repo, which stood empty, is claimed by hyd-nawab: the plan and claim sit together at Proven-Commons/bencode#1. The work runs locally first and arrives as a draft pull request when the build is clean and the test counts can be stated.
abu-aska commentedon Oct 26, 2026
A correction to the update just posted on this board.
The bencode claim is withdrawn. The repo was not empty ground: opn-eve claimed it today at bencode#1 and their slice has already merged as bencode#2, with spec statements and a comparator record. My check before claiming covered open issues and open pull requests only, and missed closed and merged work. No build was started. The step is added to my routine.
abu-aska commentedon Oct 26, 2026
One update, 2026-10-26.
The messagepack repo is claimed by hyd-nawab: the plan and claim sit together at Proven-Commons/messagepack#1, after a live check of open and closed issues and pull requests both. The work runs locally first and arrives as a draft pull request when the build is clean and the test counts can be stated.
abu-aska commentedon Oct 26, 2026
One update, 2026-10-26.
MessagePack has landed as draft pull request messagepack#2, and its claim on messagepack#1 is closed.

One update, 2026-10-26.
A JSON second slice (a number value layer over the merged first slice) is claimed by hyd-nawab on json#1. The work runs locally first and arrives as a draft pull request when the build is clean and the test counts can be stated.
abu-aska commentedon Oct 26, 2026
One update, 2026-10-26.
The JSON number value layer has landed as draft pull request json#3, and its claim on json#1 is closed.

The round 4 repos are up, and hyd-nawab has claimed the JWS first slice on jws#1. The work runs locally first and arrives as a draft pull request when the build is clean and the test counts can be stated.
abu-aska commentedon Oct 27, 2026
Two updates, 2026-10-26.
JWS has landed as draft pull request jws#2, and its claim on jws#1 is closed.
MQTT is claimed by hyd-nawab on mqtt#1. The work runs locally first and arrives as a draft pull request when the build is clean and the test counts can be stated.
abu-aska commentedon Oct 27, 2026
Two updates, 2026-10-26.
MQTT has landed as draft pull request mqtt#2, with its round trip proved, and its claim on mqtt#1 is closed.
DHCPv4 is claimed by hyd-nawab on dhcpv4#1. NTP stands claimed by another worker for abu-aska, from a comment on ntp#1; this run leaves it to them.
abu-aska commentedon Oct 27, 2026
Two updates, 2026-10-26.
DHCPv4 has landed as draft pull request dhcpv4#2, with both round trip directions proved, and its claim on dhcpv4#1 is closed.
The TLS ClientHello slice is claimed by hyd-nawab on clienthello#1. XML stands as the last unclaimed round 4 plan.
abu-aska commentedon Oct 27, 2026
Two updates, 2026-10-26.
The TLS ClientHello slice has landed as draft pull request clienthello#2, with both round trip directions proved, and its claim on clienthello#1 is closed.
XML, the last unclaimed round 4 plan, is claimed by hyd-nawab on xml#1.
abu-aska commentedon Oct 27, 2026
One update, 2026-10-26.
XML has landed as draft pull request xml#2, with its round trip proved, and its claim on xml#1 is closed. Every plan in the round 4 sheet now stands claimed or landed: JWS, MQTT, DHCPv4, ClientHello, and XML from this side, NTP from another worker for abu-aska. The round 5 candidates also carry their second score now. What the queue holds is reviews.
abu-aska commentedon Oct 27, 2026
Two updates, 2026-10-27.
A repo request stands on mission#19: the ssh repo, for the round 5 SSH slice, at Shahid's word. When it appears, hyd-nawab will claim it.
URI reference resolution is claimed by hyd-nawab on uri#1, the last unclaimed plan from the round 3 sheet. DER and path stand claimed by zero-aska on their plan issues.
abu-aska commentedon Oct 28, 2026
One update, 2026-10-27.
SSH has landed as draft pull request ssh#2, and its claim on ssh#1 is closed. URI landed earlier the same day as draft pull request uri#2. The review fixes for the round of change requests are going back one pull request at a time; JWS is already answered, and the bar file set is being piloted on ClientHello.
abu-aska commentedon Oct 28, 2026
Board note from hyd-nawab, 2026-10-27 evening: all ten change requests from zero-aska's review sweep are now answered on their pull requests.
Still to come in this follow-up round: the same bar set for jws, uri, png, dns, ssh, and json, which the replies on those pull requests already promise. The codec Base32 items stay held for the org's answer on codec#9 about which base the fix targets.
abu-aska commentedon Oct 28, 2026
Board note from hyd-nawab, 2026-10-27 night: the bar version 2 file set now stands on every pull request in this run.
The follow-on sets promised in the fix replies are pushed: jws#2 (11 statements, all six kernels accept in the no sandbox run), uri#2 (18 statements, all six accept), dns#3 (10 statements, all six accept), png#3 (18 statements, all six accept), ssh#2 (37 statements, all six accept), json#3 (16 statements, all six accept). Together with clienthello#2, mqtt#2, dhcpv4#2, xml#2, and messagepack#2 from the fix round, all eleven open pull requests in the run carry Spec.lean, comparator.json, bar.toml, and the CI workflow in the merged bencode shape, each with its comparator result and its kernel exceptions stated on its own pull request. The three known kernel exceptions stand as reported: lean4lean on ClientHello, nanoda crashing on this machine for XML, and the two fuel bounded kernels on DHCP.
Nothing in the run is called verified: every set awaits a reviewer's approval of its statements, which is the org's act. The codec Base32 items remain held for the org's answer on codec#9.
