### Updates #### 1. Status Section - Updated Status to reflect all completed steps (1, 2-A/B/D, 2-E) - Documented parity verification success #### 2. Completion Status Section (NEW) - Added dedicated section for Phase 91 Step 2 completion - Listed all deliverables with checkmarks - Documented test results: 1062/1062 PASS #### 3. Next Steps - Clarified Phase 92 lowering requirements - Updated timeline expectations #### 4. Test Fixture Fix - Fixed syntax error in test_pattern5b_escape_minimal.hako (field declarations: changed `console: ConsoleBox` to `console ConsoleBox`) ### Context Phase 91 Step 2 is now fully complete: - ✅ AST recognizer (detect_escape_skip_pattern) - ✅ Canonicalizer integration (UpdateKind::ConditionalStep) - ✅ Unit tests (test_escape_skip_pattern_recognition) - ✅ Parity verification (strict mode green) Ready for Phase 92 lowering implementation. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Haiku 4.5 <noreply@anthropic.com>

// Minimal Pattern P5b (Escape Handling) Test Fixture
|
|
// Purpose: Verify JoinIR Canonicalizer recognition of escape sequence patterns
|
|
//
|
|
// Pattern: loop(i < n) with conditional increment on escape character
|
|
// Carriers: i (position), out (accumulator)
|
|
// Exit: break on quote character
|
|
//
|
|
// This pattern is common in string parsing:
|
|
// - JSON string readers
|
|
// - CSV parsers
|
|
// - Template engines
|
|
// - Escape sequence handlers
|
|

static box Main {
|
|
console ConsoleBox
|
|
|
|
main() {
|
|
me.console = new ConsoleBox()
|
|
|
|
// Test data: string with escape sequence
|
|
// Original: "hello\" world"
|
|
// After parsing: hello" world
|
|
local s = "hello\\\" world"
|
|
local n = s.length()
|
|
local i = 0
|
|
local out = ""
|
|
|
|
// Pattern P5b: Escape sequence handling loop
|
|
// - Header: loop(i < n)
|
|
// - Escape check: if ch == "\\" { i = i + 1 }
|
|
// - Process: out = out + ch
|
|
// - Update: i = i + 1
|
|
loop(i < n) {
|
|
local ch = s.substring(i, i + 1)
|
|
|
|
// Break on quote (string boundary)
|
|
if ch == "\"" {
|
|
break
|
|
}
|
|
|
|
// Handle escape sequence: skip the escape char itself
|
|
if ch == "\\" {
|
|
i = i + 1 // Skip escape character (i increments by +2 total with final i++)
|
|
if i < n {
|
|
ch = s.substring(i, i + 1)
|
|
}
|
|
}
|
|
|
|
// Accumulate processed character
|
|
out = out + ch
|
|
i = i + 1 // Standard increment
|
|
}
|
|
|
|
// Expected output: hello" world (escape removed)
|
|
me.console.log(out)
