Thought for 5 mins 39 sec

Done.

Summary

Table

Area	Result
Datasheet URL	Added official Hirose URL to the project
MPN	Present: `DF40HC_3.0_-100DS-0.4V_51_`
Manufacturer	Project description mentions Hirose, but there is no explicit `Manufacturer Name` property
Pin count	Symbol has 100 terminals; footprint has 100 pads
Pin numbering	Terminals appear to cover 1..100 exactly once
Symbol pin metadata	Only `Pin Number`, `Pin Type`, and symbol position are present
Footprint check	Pad count matches symbol pin count, but geometry could not be fully verified against datasheet text
Mismatches flagged	Yes - see below

What I updated

Added Datasheet URL:
- https://www.hirose.com/en/product/document?clcode=&productname=&series=DF40&documenttype=Catalog&lang=en&documentid=en_DF40_CAT

Key specs I could verify

From the official/distributor product data I could confirm:

Manufacturer: Hirose Electric
Series: DF40
Part: DF40HC(3.0)-100DS-0.4V(51)
Type: board-to-board / mezzanine receptacle
Positions: 100
Pitch: 0.40 mm
Stack height variant: 3.0 mm
Mounting style: Surface Mount

Cross-check results

Table

Check	Status	Notes
MPN present	OK	Matches project intent
Datasheet URL present	Fixed	Was missing as a property; now added
Symbol pin count vs part	OK	100 terminals present
Footprint pad count vs part	OK	100 pads present
Symbol numbering continuity	OK	Pins appear numbered 1..100 once each
Pin descriptions vs datasheet	Incomplete	No per-pin descriptions/functions populated
Pin names vs datasheet	Incomplete	Terminals are named only by number
Pin type classification	Plausible but not fully verified	All pins are set to `Passive`, which is reasonable for a passive connector
Metadata completeness	Incomplete	Missing explicit `Manufacturer Name`, `Part Type`, `Package or Case Code`
Prefix consistency	Mismatch	Project-level prefix is `J`, terminal-level prefix is `P`
Footprint geometry vs datasheet land pattern	Not fully verified	I could confirm pad count, but not full mechanical dimensions from the datasheet text

Mismatches / issues flagged

Prefix inconsistency
- Project property uses J
- Individual terminals use P
Missing metadata
- No explicit Manufacturer Name
- No explicit Part Type
- No explicit Package or Case Code
Weak project description
- Current description is not a clear part summary
Pin metadata is minimal
- No pin names/descriptions beyond numeric labels
Mechanical verification incomplete
- I could confirm 100 pads, but not fully compare pad geometry/outline to Hirose land-pattern data because the datasheet/catalog text was not machine-readable in this session

Recommendation

The part is structurally close:

symbol count matches,
footprint pad count matches,
numbering looks consistent.

The main cleanup items are:

add missing part metadata,
resolve J vs P prefix inconsistency,
improve description,
optionally add short pin descriptions if you want a more polished library part.

If you want, I can do the next cleanup pass and update:

Manufacturer Name
Part Type
Package or Case Code
project description
terminal prefix consistency

Fix all mismatches

Check missing datasheets

Prioritize critical parts
