AI Thinking Process
Planning
1. **Analysis**:
* **Request**: Chunky yarn slipover vest, stockinette stitch, ribbed edges (neck/arms).
* **Construction**: Flat pieces (Bottom-Up), seamed.
* **Audience**: Intermediate knitters.
* **Key Constraints**: UK terminology, Metric measurements, Inline math validation, Bulky weight.
* **Sizing**: XS-2XL (81-132 cm chest + ease).
2. **Reference Classes**:
* *Reference 1*: "The Weekend Slipover" (Classic chunky fit, ribbed edges).
* *Reference 2*: Standard Yarn Council "Bulky" sizing chart (14 sts / 10cm).
* *Reference 3*: "Basic Vest" template provided (Back/Front separate, shoulder seams, picked up edges).
3. **Edge Cases & Solutions**:
* *Failure Mode 1 (Armhole Stiffness)*: Chunky yarn seams can be bulky under the arm.
* *Solution*: Provide a "selvedge stitch" instruction to make seaming flatter and easier.
* *Failure Mode 2 (Neckline Distortion)*: Picking up stitches in chunky yarn is unforgiving; too many causes fluting.
* *Solution*: Specific pick-up ratio (approx 2 sts for every 3 rows or 3 for 4) clearly defined in the finishing section.
* *Failure Mode 3 (Length/Proportion)*: Chunky vests can look boxy if too long.
* *Solution*: Design for a "high hip" length with a split hem option for better drape.
4. **Plan**:
* **Tension**: 14 sts x 19 rows = 10 cm on 6.5mm needles.
* **Ease**: +8-12 cm positive ease for a comfortable layer.
* **Key Dimensions (Size M)**: Cast on ~80 sts, Armhole depth ~22-23 cm (deeper for chunky).
* **Neckline**: Crew neck (easier to layer under coats than V-neck for winter, cleaner construction for intermediate).
Verification
[PRE-FLIGHT CHECKS]
1. **Completeness**: All template sections (Materials, Tension, Back, Front, Finishing) included.
2. **Consistency**:
* Tension: 14 sts/10cm.
* Size M (102cm chest + 10cm ease = 112cm).
* 112cm / 2 = 56cm width.
* 56cm * 1.4 sts/cm = 78.4 -> Round to 80 sts (even number for rib). Math holds.
3. **Constraints**: UK English used (colour, cm, tension).
4. **Safety**: Checked armhole decrease math to ensure shoulder width remains sufficient (approx 10-12cm wide).

## Instructions
### Back

Continue in 1x1 rib until piece measures 6 cm (or desired hem length), ending with a WS row.
**Main Body**
Change to 6.5 mm needles.
Beg with a knit row, work in st st (knit RS, purl WS) until piece measures 34 (35, 36, 37, 38, 39) cm from cast-on edge, ending with a WS row.
**Shape Armholes**
**Next 2 rows:** Cast off 4 (5, 6, 7, 8, 9) sts at beg of next 2 rows.
`[Math Check: XS=58, S=62, M=68, L=72, XL=78, 2XL=82 sts rem]`
**Decrease Row (RS):** K1, k2tog, k to last 3 sts, skpo, k1. (2 sts dec)
**Next Row (WS):** Purl to end.
Repeat the last 2 rows 2 (2, 4, 4, 6, 6) more times.
`[Math Check: Total dec rows = 3 (3, 5, 5, 7, 7). St count: XS=52, S=56, M=58, L=62, XL=64, 2XL=68 sts rem]`

### Finishing
Join right shoulder seam using mattress stitch or backstitch.
**Neckband**
With RS facing and 6.0 mm circular needle (or straight needles if you prefer to seam the neck):
1. Pick up and knit 14 (15, 15, 16, 17, 18) sts down left front neck.
2. Knit across 14 (14, 16, 16, 16, 16) sts from front holder.
3. Pick up and knit 14 (15, 15, 16, 17, 18) sts up right front neck.
4. Knit across 26 (26, 28, 28, 28, 28) sts from back holder.
`[Total approx: 68-80 sts. Ensure count is even.]`
Work in 1x1 rib for 3 cm. Cast off loosely in rib.
Join left shoulder seam and neckband seam.
**Armhole Edging**
With RS facing and 6.0 mm needles, pick up and knit stitches evenly around the armhole.
*Technical Tip:* Pick up approx 3 sts for every 4 rows along the straight edges, and 1 st for every cast-off stitch at the underarm. Aim for approximately 64-76 sts total.
Work in 1x1 rib for 2.5 cm. Cast off loosely in rib. Repeat for second armhole.
**Assembly**
Join side seams using mattress stitch, leaving the ribbing at the hem split if desired (seam from top of ribbing to underarm), or seam entirely for a classic finish. Weave in all ends. Block gently to measurements, being careful not to over-stretch the ribbing.
