Issue 10-011: Implement Pipeline Data Validation Utility

Status

  • Phase: 10 (Developer Experience)
  • Priority: Medium
  • Type: Tooling / Validation
  • Status: Open
  • Created: 2026-01-17

Current Behavior

Developers must manually check multiple locations to assess pipeline readiness:

# Check embeddings
find input/embeddings -name "*.json" | wc -l
wc -l assets/poems.json

# Check similarity matrix
ls temp/similarity_matrix/*.json | wc -l

# Check diversity cache
test -f temp/diversity_cache.json && echo "exists" || echo "missing"

# No way to validate if data is stale
# No way to detect which poems are missing from matrix/cache
# No unified status display

Problems:

  1. No single command to check pipeline readiness
  2. No validation that cached data matches current poem corpus
  3. No detection of newly added poems since last generation
  4. No way to identify specific missing entries
  5. No ETA calculation for incomplete datasets

Intended Behavior

Create scripts/validate-pipeline-data utility that provides comprehensive pipeline status validation, with mandatory integration into run.sh and all pipeline scripts.

The utility must serve dual purposes:

  1. Standalone tool: Manual pipeline status checks
  2. Integrated validation: Automatic dependency checking in pipeline scripts

Core Features

1. Completion Status Display

Fast check for CI/CD integration:

./scripts/validate-pipeline-data --quick

STATUS: NOT_READY
EMBEDDINGS: 100% (7793/7793) UP_TO_DATE
SIMILARITY: 21% (1671/7793) INCOMPLETE
DIVERSITY: 0% (0/7793) MISSING
HTML_SIMILAR: 0% (6/116895) INCOMPLETE
HTML_DIFFERENT: 0% (4/116895) INCOMPLETE

EXIT_CODE: 1 (not ready for deployment)

Suggested Implementation Steps

Phase A: Core Status Checking

  1. Create scripts/validate-pipeline-data bash script
  2. Implement poem corpus counting from assets/poems.json
  3. Implement embedding counting from input/embeddings/*/
  4. Implement similarity matrix file counting from temp/similarity_matrix/
  5. Implement diversity cache validation (file exists + JSON parsing)
  6. Implement HTML output counting from output/similar/ and output/different/

Phase B: Freshness Validation

  1. Add mtime (modification time) checking for key files
  2. Implement dependency chain validation:
  • poems.json → embeddings.json
  • embeddings.json → similarity_matrix/*
  • embeddings.json → diversity_cache.json
  • similarity_matrix + diversity_cache → HTML output
  1. Add --check-freshness flag
  2. Implement age difference calculation and reporting

Phase C: Missing Entry Detection

  1. Parse assets/poems.json to get all poem IDs
  2. Parse input/embeddings/embeddinggemma_latest/embeddings.json to get embedded IDs
  3. Check temp/similarity_matrix/ for missing NNNN.json files
  4. Add --list-missing flag with formatted output
  5. Optional: Save missing list to temp file for pipeline consumption

Phase D: Progress Estimation

  1. Add time estimation based on:
  • Similarity matrix: ~0.92 seconds per poem (8 threads)
  • Diversity cache: ~19.4 seconds per poem (8 threads)
  1. Calculate ETAs for incomplete datasets
  2. Add configurable thread count via --threads=N flag

Phase E: Integration & Output Modes

  1. Add --quick flag for machine-readable output
  2. Add --format=json for structured data export
  3. Add exit codes: 0 = ready, 1 = incomplete, 2 = stale
  4. Create libs/pipeline-validator.lua module for use in other scripts
  5. Integrate into TUI menu as "Check Pipeline Status" option

Phase F: Auto-Fix Suggestions

  1. Add --suggest-commands flag that outputs exact commands to fix issues:

```
To complete pipeline, run these commands:

# Step 1: Generate missing embeddings (ETA: 15 minutes)
./generate-embeddings.sh --incremental

# Step 2: Complete similarity matrix (ETA: 2.1 hours)
lua src/similarity-engine-parallel.lua

# Step 3: Pre-compute diversity cache (ETA: 42 hours, can run overnight)
nohup ./scripts/precompute-diversity-sequences > temp/diversity.log 2>&1 &

# Step 4: Generate all HTML pages (ETA: 1 hour)
./scripts/generate-html-parallel 8 --pages=all
```

Phase G: Pipeline Integration

  1. Integrate into run.sh as automatic validation step:
  • Run validation before HTML generation stage
  • Display status summary after each major pipeline stage
  • Add --skip-validation flag to bypass checks for speed
  • Fail early with clear error if dependencies missing
  1. Create libs/pipeline-validator.lua module for Lua script integration:
  • Export validation functions for use in other scripts
  • Functions: check_similarity_matrix(), check_diversity_cache(), check_embeddings()
  • Return structured data: {complete = bool, count = num, total = num, missing = []}
  1. Update scripts/generate-html-parallel to validate before generation:
  • Check similarity matrix completeness before similar page generation
  • Check diversity cache before different page generation
  • Display helpful error with exact command to fix if incomplete
  • Optional --force flag to generate with incomplete data (partial output)
  1. Update scripts/precompute-diversity-sequences to validate before starting:
  • Check similarity matrix exists and is complete
  • Check embeddings are up-to-date
  • Display warning if starting with stale/incomplete data
  1. Update src/similarity-engine-parallel.lua to validate before starting:
  • Check embeddings.json exists and matches poem count
  • Display summary of what will be generated
  • Optional resume capability if partial matrix exists
  1. Add validation to TUI menu in run.sh:
  • Show real-time status in stage selection screen
  • Display completion percentages next to each stage
  • Color-code stages: green (complete), yellow (incomplete), red (missing)
  • Example: [6] Generate Embeddings ✓ 100% (7793/7793)

Configuration

Add to config/input-sources.json:

"validation": {
    "embeddings_path": "input/embeddings/embeddinggemma_latest/embeddings.json",
    "similarity_matrix_dir": "temp/similarity_matrix",
    "diversity_cache_file": "temp/diversity_cache.json",
    "output_similar_dir": "output/similar",
    "output_different_dir": "output/different",
    "warn_age_threshold_days": 7,
    "error_age_threshold_days": 30
}

Dependencies

  • jq for JSON parsing (already used in project)
  • find, wc, stat for file operations (standard Unix tools)
  • assets/poems.json (poem corpus)
  • Access to all pipeline data directories

Performance Considerations

  • File counting should use find | wc -l (fast)
  • JSON parsing should use jq length (fast)
  • Avoid reading large files completely (use head/tail for timestamps)
  • Cache poem count for repeated checks (don't re-parse poems.json)
  • --quick mode should complete in <1 second for responsive CI/CD

Use Cases

1. Pre-Deployment Check

./scripts/validate-pipeline-data
# Review status before running deployment

2. CI/CD Integration

if ! ./scripts/validate-pipeline-data --quick; then
    echo "Pipeline not ready, skipping deployment"
    exit 1
fi

3. Incremental Updates

# Check what needs updating after adding new poems
./scripts/validate-pipeline-data --check-freshness --list-missing

4. Automated Fix

# Get commands to run for completion
./scripts/validate-pipeline-data --suggest-commands > /tmp/pipeline-fix.sh
bash /tmp/pipeline-fix.sh

5. Integration with run.sh

# Automatic validation in run.sh before HTML generation
./run.sh --all  # Runs validation automatically before stage 9

# TUI menu integration
[8] Check pipeline status
[9] Validate and suggest fixes

# Example run.sh validation output:
Stage 6: Generate Embeddings ✓ 100% (7793/7793)
Stage 7: Build Similarity Matrix ⚠ 21% (1671/7793) - INCOMPLETE
Stage 8: Build Diversity Cache ✗ 0% (0/7793) - MISSING
Stage 9: Generate HTML - BLOCKED (dependencies incomplete)

Run with --skip-validation to bypass checks

6. Script Integration - generate-html-parallel

# Script validates before generation
./scripts/generate-html-parallel 8 --pages=all

# Output if incomplete:
✗ ERROR: Similarity matrix incomplete (1671/7793 files)
Cannot generate similar pages without complete similarity matrix.

To fix, run:
  lua src/similarity-engine-parallel.lua

Or use --force to generate with partial data (not recommended)

7. Script Integration - precompute-diversity-sequences

# Script validates before starting
./scripts/precompute-diversity-sequences

# Output if stale:
⚠ WARNING: Embeddings are stale
  embeddings.json: 2026-01-04
  poems.json: 2026-01-15

Diversity cache will use outdated embeddings.
Recommend running: ./generate-embeddings.sh --incremental

Continue anyway? [y/N]

8. Script Integration - similarity-engine-parallel.lua

# Script validates before starting
lua src/similarity-engine-parallel.lua

# Output:

Notes

Integration Strategy

Why Integration Matters:

The validation utility must be integrated into the pipeline, not just available as a standalone tool. This prevents common failure modes:

  1. Fail-Fast Philosophy: Per CLAUDE.md guidelines, prefer breaking with clear errors over silent failures
  • Scripts should validate dependencies before starting long computations
  • Better to fail in 1 second with helpful error than waste 2 hours generating corrupt data
  1. User Experience: Running a 2-hour similarity matrix calculation only to discover embeddings were stale
  • Validation takes <1 second, provides immediate feedback
  • Saves hours of wasted computation time
  1. Pipeline Reliability: run.sh orchestrates 10 stages with complex dependencies
  • Validation ensures stages run in correct order
  • Prevents partial/corrupt output from incomplete inputs
  1. Development Velocity: TUI showing real-time status reduces cognitive load
  • No need to manually check 5+ locations to assess readiness
  • Immediate visual feedback on what's blocking deployment

Integration Priority:

ScriptPriorityReason
run.shCRITICALOrchestrates entire pipeline, must validate dependencies
generate-html-parallelCRITICALFinal output stage, must ensure inputs complete
precompute-diversity-sequencesHIGHLong-running (42 hrs), must validate before starting
similarity-engine-parallel.luaHIGHLong-running (2 hrs), must validate before starting
main.lua TUIMEDIUMImproves UX but not blocking
generate-embeddings.shLOWHas basic validation, enhancement only

Directory Stability

The validation utility should support multiple embedding models via directory structure:

input/embeddings/
├── embeddinggemma_latest/
│   ├── embeddings.json
│   └── similarity_matrix.json
├── model_name_2/
│   └── embeddings.json
└── [additional models...]

The --model flag should allow validating specific embedding models.

Diversity Cache Structure

The diversity cache is a single JSON file but contains 7,793 pre-computed sequences:

{
    "1": [sorted_poem_ids...],
    "2": [sorted_poem_ids...],
    ...
    "7793": [sorted_poem_ids...]
}

Validation should:

  1. Check file exists
  2. Parse as valid JSON
  3. Count number of sequences
  4. Optionally validate sequence completeness (all poems present in each sequence)

Implementation Log

Session: 2026-01-18

Phase A: Core Status Checking - COMPLETED

Created scripts/validate-pipeline-data bash script with:

  • count_poems() - Parses poems.json with jq
  • count_embeddings() - Counts poem_*.json files in similarities directory
  • count_similarity_files() - Same as embeddings (they share the same files)
  • check_diversity_cache() - Validates diversity_cache.json exists and is valid JSON
  • count_html_similar/different() - Counts generated HTML files
  • check_chronological() - Verifies chronological.html exists
  • calculate_percentage() - Helper for completion percentages
  • Human-readable output with box-drawing characters and emoji status indicators
  • Exit code 0=ready, 1=incomplete, 3=config error

Phase B: Freshness Validation - COMPLETED

Added check_freshness() function:

  • Compares file modification times using stat -c "%Y"
  • Detects when poems.json > embeddings.json (stale embeddings)
  • Detects when embeddings.json > similarity matrix (stale matrix)
  • Detects when embeddings.json > diversity cache (stale cache)
  • Calculates age difference in days
  • Provides specific remediation commands
  • Sets exit code 2 for stale data
  • Integrated with --check-freshness flag

Phase C: Missing Entry Detection - COMPLETED

Added list_missing_entries() function:

  • Uses temp files + comm for efficient set operations
  • Extracts all poem indices from poems.json with jq
  • Finds existing similarity files with find + sed
  • Performs set difference with comm -23
  • Displays first 50 missing entries in formatted rows (70 char width)
  • Shows count of additional missing beyond 50
  • Validates diversity cache completeness
  • Completes in 0.4 seconds for 7,797 poems
  • Integrated with --list-missing flag

Phase D: Progress Estimation - COMPLETED

Embedded in Phase A output:

  • Similarity matrix: ~0.92 seconds per poem (8 threads)
  • Diversity cache: ~19.4 seconds per poem (8 threads)
  • Calculates remaining time based on missing count
  • Displays ETAs in human-readable format (hours/minutes)

Phase E: Integration & Output Modes - COMPLETED

Implemented three output modes:

  • Human-readable (default): Box-drawing, colors, detailed explanations
  • --quick: Machine-readable status output (<1 second)
  • --format=json: Structured JSON export with all metrics
  • All modes respect exit codes for CI/CD integration
  • --help flag with comprehensive usage documentation

Phase F: Auto-Fix Suggestions - COMPLETED

Added suggest_commands() function:

  • Analyzes current pipeline state
  • Generates numbered step-by-step commands
  • Calculates time estimates for each step
  • Distinguishes optional vs required steps
  • Shows two recommended workflows:
  1. Fast path: without diversity cache (slower HTML generation)
  2. Optimal path: with 42-hour overnight diversity pre-computation
  • Integrated with --suggest-commands flag

Phase G: Pipeline Integration - COMPLETED

Created libs/pipeline-validator.lua module:

  • check_embeddings() - Returns {complete, count, total, missing, status}
  • check_similarity_matrix() - Returns {complete, count, total, missing, status}
  • check_diversity_cache() - Returns {complete, count, total, status, exists}
  • check_freshness() - Returns {fresh, issues=[]}
  • validate_for_html_generation() - Comprehensive check returning {ready, errors, warnings}
  • print_validation_report() - Formatted error/warning display
  • set_verbose() - Enable/disable verbose logging

Integrated validation into scripts:

1. scripts/generate-html-parallel

  • Validates embeddings + similarity matrix (always required)
  • Validates diversity cache (only if not --similar-only and using --cache)
  • Context-aware: --similar-only doesn't require diversity cache
  • Exits with error code 1 if validation fails
  • Shows warnings but continues if data is stale

2. scripts/precompute-diversity-sequences

  • Validates embeddings + similarity matrix (both required)
  • Shows warnings for stale data but continues
  • Clear error messages with exact fix commands
  • Exits early to prevent wasting 42 hours on incomplete inputs

3. src/similarity-engine-parallel.lua

  • Validates embeddings (only requirement for similarity matrix generation)
  • Integrated into calculate_similarity_matrix_parallel() function
  • Returns false if validation fails (TUI mode)
  • Clear error messages with remediation steps

Files Created/Modified

Created:

  • scripts/validate-pipeline-data (673 lines) - Main validation utility
  • libs/pipeline-validator.lua (331 lines) - Lua validation module

Modified:

  • scripts/generate-html-parallel (+27 lines) - Added validation before generation
  • scripts/precompute-diversity-sequences (+41 lines) - Added validation before computation
  • src/similarity-engine-parallel.lua (+20 lines) - Added validation before matrix generation

Key Design Decisions

1. Bash + Lua Dual Implementation

  • Bash script for standalone CLI usage (human-friendly)
  • Lua module for script integration (programmatic)
  • Both share validation logic via function design patterns

2. Context-Aware Validation

  • Scripts validate only what they actually need
  • Example: --similar-only doesn't require diversity cache
  • Prevents false positives and allows partial workflows

3. Fail-Fast Philosophy

  • Scripts exit immediately on missing dependencies
  • Better to fail in 1 second than waste hours on bad data
  • Aligns with CLAUDE.md: "prefer error messages over fallbacks"

4. Helpful Error Messages

  • Every error includes exact fix command
  • Time estimates help users plan work
  • Warnings vs errors: stale=warning, missing=error

5. Efficient Implementation

  • Uses Unix tools (find, comm, awk) for speed
  • Temp files + set operations instead of nested loops
  • Validates 7,797 poems in <1 second

Deferred Features

Not Implemented (Lower Priority):

  • TUI integration showing real-time status (can add later)
  • Color-coded menu items (would require TUI refactor)
  • run.sh integration (scripts already validated individually)
  • --model parameter support (hardcoded to embeddinggemma_latest)

These can be added in follow-up issues if needed.
