Bad text stays visible

Change a valid invoice reference to malformed text and watch the raw input stay visible while an anchored parse guard returns unparsed and closes the decision as rejected.

Expected checkpoint

A known state for this walkthrough.

After loading the canonical invoice and owner text.

Invoice valid: TRUEA4 and A7
Extracted year: 2026A5
Normalized text: priority:urgent owner:sharedA6
Classification: :accepted / currentB1 / B2
Division fallback: 0B3

01 · Validate

Two independent checks admit the invoice

Regex validates the complete shape while a glob checks the expected suffix.

02 · Normalize

Capture and replacement produce reusable text

The year becomes a stable field and owner data is rewritten without changing the raw source.

03 · Recover

Errors and blanks become explicit policy

TRY and DEFAULT keep downstream classification readable.

MODEL "Text And Quality"
DESCRIPTION "Portable model for classification, text cleanup, and defensive parsing."
VERSION "1.0.0"
AUTHOR "Grid Team"
TAGS "canonical", "portable", "text", "quality"

# Raw text inputs
A1 = "INV-2026-001"
A2 = "priority:urgent owner:ops"
A3 = raw"^INV-\d+-\d+$"

# Parsing and cleanup
A4 = REGEXMATCH(A1, A3)
A5 = REGEXEXTRACT(A1, /INV-(\d+)/)
A6 = REGEXREPLACE(A2, /owner:\w+/, "owner:shared")
A7 = WILDCARDMATCH(A1, glob"INV-*-001")

# Classifications
B1 = A4 AND A7 THEN :accepted ELSE :rejected
B2 = MATCH(A5, "2025" -> "legacy", "2026" -> "current", _ -> "other")
B3 = TRY 10 / 0 ELSE 0
B4 = BLANK DEFAULT "unassigned"
B5 = `invoice={A1} year={A5} state={B1}`
