Session: 12:37 AM - Context Resumption - UTF-8 Character Boundary Fix

Environment: Claude Code CLI | /Users/evan/Downloads/data-2025-10-13-11-23-05-batch-0000/claude_convo_exporter | branch: fix/truncate-char-boundary | Resumed session Context Markers Since Last TLDR: 6 entries covering archaeology synthesis → chunking implementation → production deployment

🔧 Problems Solved

Problem: Panic when truncating strings containing multi-byte UTF-8 characters (emojis, special chars)

thread 'main' panicked at floatctl-embed/src/lib.rs:359:28:
byte index 47 is not a char boundary; it is inside '"' (bytes 46..49)

Solution: Replaced byte-based indexing with character-based indexing

// BEFORE (buggy):
format!("{}...", &s[..max_len.saturating_sub(3)])  // byte index

// AFTER (safe):
let target_len = max_len.saturating_sub(3);
let truncate_at = s
    .char_indices()
    .nth(target_len)
    .map(|(idx, _)| idx)
    .unwrap_or(s.len());
format!("{}...", &s[..truncate_at])  // character boundary

Technical reasoning: Rust strings are UTF-8 encoded where characters can be 1-4 bytes. Direct byte indexing can fall inside a multi-byte character encoding, causing a panic. char_indices() iterator provides byte positions that are guaranteed to be at character boundaries.

🌀 Context Evolution (from ctx:: markers)

Timeline of floatctl-rs evolution (from recent context):

  1. Oct 13 @ 6:53 PM: Rust rewrite complete (three iterations, 6.5s performance)
  2. Oct 13 @ 10:08 PM: Better error handling, rate limiting, stdin support
  3. Oct 14 @ 2:30 AM: Chunking implementation (paragraph/sentence boundaries)
  4. Oct 14 @ 10:56 PM: PR #2 created, production deployment begins
  5. Oct 14 @ 11:03 PM: Discovered chunking edge cases (8,329 tokens exceeds limit)
  6. Oct 14 @ 12:37 AM (this session): Fixed UTF-8 character boundary bug

Mode shifts observed:

Project context bridging:

📍 Next Actions

Based on completed work and recent context markers:

  1. Review and merge PR #4 (truncate fix) - all tests pass, ready for review
  2. Address chunking edge cases (from Oct 14 @ 11:03 PM context marker):
    • Lower MAX_TOKENS from 8000 to 7500 or 7000
    • Improve sentence splitting logic for edge cases
    • Add hard fallback: if chunk > 8000 tokens, truncate with warning
    • Document batch-size limits in README (max ~100 to stay under 300K token limit)
  3. Continue embedding production deployment:
    • Process October 2025 conversations first (302 conversations)
    • Then September (571 conversations)
    • Monitor for any additional edge cases
  4. Test EVNA-Next pgvector integration once embeddings populate database

Immediate priority: Merge PR #4 (truncate fix) since it’s blocking production progress bars from displaying correctly.

Session: 12:37 AM - 01:31 AM - Lossy UTF-8 Decoding Recovery

Environment: Claude Code CLI | /Users/evan/Downloads/data-2025-10-13-11-23-05-batch-0000/claude_convo_exporter | branch: fix/truncate-char-boundary | Production debugging Context Markers Since Last TLDR: 2 entries (Float systems architecture synthesis, Rangle pharmacy sync)

🎯 Major Accomplishments

💡 Key Insights

🔧 Problems Solved

Problem: Token decoding failure during message chunking

Error: Failed to decode tokens: Unable to decode into a valid UTF-8 string:
invalid utf-8 sequence of 1 bytes from index 0

Context: Processing large Python script (#!/usr/bin/env python3)
Chunking: 30,696 tokens → 6 chunks

Solution: Segmented decode with partial recovery

// Try full chunk decode first
match BPE.decode(chunk_tokens.to_vec()) {
    Ok(text) => text,
    Err(e) => {
        // Break into 100-token segments
        let mut recovered = String::new();
        for segment in chunk_tokens.chunks(100) {
            match BPE.decode(segment.to_vec()) {
                Ok(text) => recovered.push_str(&text),
                Err(_) => recovered.push('�'), // Replacement char
            }
        }
        recovered
    }

🌀 Context Evolution (from ctx:: markers)

Recent context entries (last 2 hours):

  1. Oct 14 @ 5:15 AM: Float systems architectural synthesis

    • Karen boundary guardian function externalization
    • Translation layer for institutional adoption
    • “Context-appropriate masks preserve soul while adapting delivery”
  2. Oct 10 @ 1:03 PM: Rangle pharmacy sync with Scott Evan

    • Project context shift to work projects

This session’s context:

📍 Next Actions

Based on this session and embedding pipeline status:

  1. Test the embedding pipeline with lossy recovery in production:

    cargo run -p floatctl-cli --release -- embed \
      --in out/messages.ndjson \
      --skip-existing \
      --batch-size 100 \
      --rate-limit-ms 500
  2. Monitor for warnings during embedding run:

    • Look for “UTF-8 decode failed, using lossy conversion” warnings
    • Track how many chunks require partial recovery
    • Verify recovered content is acceptable quality
  3. Consider PR strategy:

    • Current branch has two fixes: truncate + lossy decode
    • Could merge as single PR or split into two
    • Both fixes related to UTF-8 safety in production
  4. Address remaining chunking issues (from earlier context markers):

    • Lower CHUNK_SIZE from 6000 to 5500 or 5000 for more buffer
    • Document batch-size limits (max ~100 to stay under 300K token limit)
    • Consider adaptive chunk sizing based on token density

Immediate priority: Run embedding pipeline with both fixes and monitor behavior in production.

Problem: Query latency killing usability

[2m2025-10-14T06:15:43.582433Z[0m [32m INFO[0m creating IVFFlat index with lists=33
[2m2025-10-14T06:16:11.752295Z[0m [33m WARN[0m slow statement: elapsed=27.944258791s

Every semantic search query taking 40+ seconds total.

Root Cause: ensure_optimal_ivfflat_index() called on every query

Solution 1: Remove from Query Path

// floatctl-embed/src/lib.rs:411-427
pub async fn run_query(args: QueryArgs) -> Result<()> {
    // ... connection setup ...

    // Note: Index creation removed from query path for performance
    // Index is created/updated during embedding runs via ensure_optimal_ivfflat_index_if_needed()

    let openai = OpenAiClient::new(api_key)?;
    // ... query execution ...
}

Solution 2: Smart Index Check

// floatctl-embed/src/lib.rs:730-786
async fn ensure_optimal_ivfflat_index_if_needed(pool: &PgPool) -> Result<()> {
    // Check if index exists
    let index_exists: (bool,) = sqlx::query_as(
        "SELECT EXISTS(SELECT 1 FROM pg_indexes WHERE indexname = 'embeddings_vector_idx')"
    ).fetch_one(pool).await?;

    if !index_exists.0 {
        info!("IVFFlat index not found, creating...");
        return ensure_optimal_ivfflat_index(pool).await;
    }

    // Get current lists parameter from pg_class.reloptions
    let current_lists_result: Result<Option<String>, _> = sqlx::query_scalar(
        "SELECT array_to_string(reloptions, ',') FROM pg_class WHERE relname = 'embeddings_vector_idx'"
    ).fetch_optional(pool).await;

    // Parse "lists=33" format and compare with optimal
    let optimal_lists = (count / 1000).max(10) as i32;
    let diff_pct = ((optimal_lists - current_lists).abs() as f64 / current_lists as f64) * 100.0;

    if diff_pct < 20.0 {
        info!("IVFFlat index already optimal (lists={}, optimal={}, row_count={})",
            current_lists, optimal_lists, count);
        return Ok(());
    }

    // Only recreate if significantly outdated
    ensure_optimal_ivfflat_index(pool).await
}

Solution 3: Update Embed Pipeline

// floatctl-embed/src/lib.rs:191-192
// Create or update IVFFlat index only if needed (smart check)
ensure_optimal_ivfflat_index_if_needed(&pool).await?;

📍 Next Actions

Based on completed optimizations and branch status:

  1. Review and Merge PR #5:

  2. Test EVNA-Next Integration:

    • Semantic search now fast enough for real-time use
    • Verify conversation context displays properly in EVNA-Next UI
    • Test marker-based filtering (project::, meeting::)
  3. Document Performance Characteristics in README:

    • Query latency: 1-2s (28x improvement)
    • Index management: automatic smart check
    • Batch size recommendations (<100 for OpenAI token limits)
    • Expected performance at scale (33K embeddings proven)
  4. Address Remaining Chunking Edge Cases (from Oct 14 @ 11:03 PM marker):

    • Lower CHUNK_SIZE from 6000 to 5500 for more buffer
    • Improve sentence splitting for edge cases
    • Add hard fallback if chunk > 8000 tokens
  5. Consider HNSW Migration (Phase 2 optimization):

    • IVFFlat: linear scaling, fast build
    • HNSW: logarithmic scaling, slower build, much faster queries
    • At 33K embeddings, HNSW would provide further speedup
    • One-time migration cost for long-term query performance

Immediate priority: Merge PR #5 - the substrate now runs at substrate speed.
