-## BEFORE START
-This project uses uv instead of pip.
-model : qwen
+# A3Service Data Pipeline
 
-## Instructions
-1 - First download uv. This site has instructions, you just need to copy paste onto the bash.
+## Purpose
 
-https://docs.astral.sh/uv/getting-started/installation/
+The A3Service data pipeline prepares boiler/manual PDF documents for the technical library used by the backend and mobile app.
 
-2 - After uv install, only thing left is go "cd data-pipeline" then "uv sync"
+The workflow is intentionally split into two separate parts:
+
+```text
+1. Manual PDF discovery/download
+2. Structured JSON extraction from downloaded PDFs
+```
+
+The downloader does not call Gemini.
+
+The extraction pipeline does not scrape websites.
+
+This separation makes the workflow easier to debug, rerun, and validate.

+
+## Local-only files
+
+The following files and folders are local/generated and should normally not be committed:
+
+```text
+.env
+.venv/
+raw_pdfs/
+logs/
+input/manual_sources.generated.json
+output_json/_debug/
+output_json/_index/downloaded_manuals.json
+output_json/_review/failed_downloads.json
+```
+
+The following generated output files may be committed when the team needs the extracted demo dataset:
+
+```text
+output_json/{Brand}/
+output_json/_index/manuals_index.json
+output_json/_index/fault_codes_index.json
+output_json/_index/processed_manuals.json
+output_json/_review/low_confidence_records.json
+output_json/_review/failed_extractions.json
+```
+
+## Environment setup
+
+From the data-pipeline folder:
+
+```bash
+cd apps/data-pipeline
+```
+
+Install dependencies:
+
+```bash
+uv sync
+```
+
+Create a local `.env` file:
+
+```env
+GEMINI_API_KEY=your_api_key_here
+GEMINI_MODEL=gemini-2.5-flash
+```
+
+Do not commit `.env`.
+
+## Manual PDF discovery and download
+
+Manual sources are configured in:
+
+```text
+input/source_registry.example.json
+```
+
+If a local custom source registry is needed, create:
+
+```text
+input/source_registry.json
+```
+
+When `source_registry.json` exists, the downloader uses it instead of the example file.
+
+### Discover manuals
+
+Discovery finds possible PDF/manual links and writes them to:
+
+```text
+input/manual_sources.generated.json
+```
+
+Examples:
+
+```bash
+uv run python download_manuals.py discover --brand Bosch
+uv run python download_manuals.py discover --brand Vaillant
+uv run python download_manuals.py discover --brand Baxi
+```
+
+### Download manuals
+
+Downloaded PDFs are saved into brand-specific folders under:
+
+```text
+raw_pdfs/
+```
+
+Examples:
+
+```bash
+uv run python download_manuals.py download --brand Bosch
+uv run python download_manuals.py download --brand Vaillant
+uv run python download_manuals.py download --brand Baxi
+```
+
+For large sources, use a small limit first:
+
+```bash
+uv run python download_manuals.py download --brand Bosch --limit 5
+```
+
+## Current downloader source status
+
+Working sources:
+
+```text
+Bosch official Home Comfort documentation pages
+Vaillant via FreeBoilerManuals
+Baxi via FreeBoilerManuals
+Direct PDF links
+```
+
+Experimental or partially manual sources:
+
+```text
+Unical official site crawler
+Viessmann official source collector
+```
+
+Unical and Viessmann may require manually verified direct PDF downloads because their site structures and download behavior are less reliable.
+
+## Structured extraction pipeline
+
+The extraction pipeline reads PDFs from:
+
+```text
+raw_pdfs/
+```
+
+It recursively finds PDFs, so brand folders work automatically.
+
+### Process all downloaded PDFs
+
+```bash
+uv run python run_pipeline.py
+```
+
+### Process one brand only
+
+```bash
+uv run python run_pipeline.py --brand Bosch
+```
+
+### Process only a few PDFs
+
+```bash
+uv run python run_pipeline.py --brand Bosch --limit 1
+```
+
+### Force reprocessing
+
+The pipeline uses file hashes to skip already processed PDFs.
+
+To reprocess already processed PDFs:
+
+```bash
+uv run python run_pipeline.py --brand Bosch --force
+```
+
+Or with a limit:
+
+```bash
+uv run python run_pipeline.py --brand Bosch --force --limit 1
+```
+
+## Recommended safe workflow
+
+For a safe test run:
+
+```bash
+uv run python download_manuals.py discover --brand Bosch
+uv run python download_manuals.py download --brand Bosch --limit 5
+uv run python run_pipeline.py --brand Bosch --limit 1
+```
+
+If the output looks good, increase the limit gradually.
+
+Do not run hundreds of manuals through Gemini before checking runtime, cost, and output quality.
+
+## Output JSON structure
+
+Structured extraction outputs are written to:
+
+```text
+output_json/
+```
+
+Example:
+
+```text
+output_json/
+  Bosch/
+    bosch_greenstar-wall-boiler_abc123.json
+
+  Vaillant/
+    vaillant_ecotec-plus_xyz789.json
+
+  Baxi/
+    baxi_duo-tec_123abc.json
+
+  Unical/
+    unical_kone_456def.json
+
+  Viessmann/
+    viessmann_vitodens_789abc.json
+
+  Buderus/
+    buderus_logamax-plus_123xyz.json
+
+  _index/
+    manuals_index.json
+    fault_codes_index.json
+    processed_manuals.json
+
+  _review/
+    low_confidence_records.json
+    failed_extractions.json
+
+  _debug/
+    raw and repaired Gemini responses
+```
+
+## Full manual JSON files
+
+Brand folders contain full extracted manual data.
+
+A full manual JSON may contain:
+
+```text
+schema_version
+document_meta
+technical_specs
+fault_codes
+diagnostic_codes
+status_codes
+safety_warnings
+maintenance_tasks
+search_terms
+derived_guidance
+extraction_meta
+```
+
+These files are the main source-of-truth extracted data.
+
+## Index files
+
+### manuals_index.json
+
+Path:
+
+```text
+output_json/_index/manuals_index.json
+```
+
+Purpose:
+
+```text
+lists successfully processed manuals
+stores brand/model/manual metadata
+points to the full output JSON file
+shows confidence and review status
+```
+
+### fault_codes_index.json
+
+Path:
+
+```text
+output_json/_index/fault_codes_index.json
+```
+
+Purpose:
+
+```text
+contains a flattened list of extracted fault codes
+supports quick search by code/component/symptom
+points back to the full manual JSON using output_file
+```
+
+If multiple brands/manuals are processed, this file contains fault-code records from all successfully processed manuals.
+
+### processed_manuals.json
+
+Path:
+
+```text
+output_json/_index/processed_manuals.json
+```
+
+Purpose:
+
+```text
+tracks processed PDF hashes
+prevents repeated Gemini calls for the same PDF
+used by pipeline skip logic
+```
+
+## Review files
+
+### low_confidence_records.json
+
+Path:
+
+```text
+output_json/_review/low_confidence_records.json
+```
+
+Purpose:
+
+```text
+collects records that require human review
+keeps uncertain or incomplete records visible
+helps identify extraction quality issues
+```
+
+A record may appear here when:
+
+```text
+confidence is low
+review_required is true
+possible causes are missing
+manufacturer steps are missing
+source references are unclear
+JSON was repaired after malformed Gemini output
+```
+
+### failed_extractions.json
+
+Path:
+
+```text
+output_json/_review/failed_extractions.json
+```
+
+Purpose:
+
+```text
+tracks manuals that failed during extraction
+helps with retry planning and debugging
+```
+
+Common failure reasons:
+
+```text
+Gemini 503 high demand
+invalid API key
+malformed response
+schema validation failure
+empty or invalid PDF
+```
+
+## Debug files
+
+Debug files are written under:
+
+```text
+output_json/_debug/
+```
+
+This folder can contain:
+
+```text
+raw Gemini responses
+repaired Gemini responses
+schema validation error logs
+```
+
+Do not commit `_debug/`.
+
+## Notes about Buderus outputs
+
+Some PDFs discovered from Bosch-related sources may be extracted under:
+
+```text
+output_json/Buderus/
+```
+
+This can happen when the actual manual/document brand is Buderus, even if the source came through Bosch Home Comfort pages.
+
+This is not automatically wrong. It should be treated as useful extracted data, but later validation should compare:
+
+```text
+source/download brand
+extracted document_meta.brand_name
+output folder brand
+```
+
+## Confidence and review_required
+
+Each extracted record may include:
+
+```text
+confidence
+review_required
+source_refs
+```
+
+Important:
+
+```text
+confidence is a review signal, not absolute proof of correctness
+review_required means the record should be checked before production use
+source_refs should be used to trace extracted data back to the manual page
+```
+
+## Windows logging issue
+
+On Windows PowerShell, emoji output can cause encoding errors.
+
+Use this before long runs:
+
+```powershell
+chcp 65001
+$env:PYTHONUTF8 = "1"
+$env:PYTHONIOENCODING = "utf-8"
+[Console]::OutputEncoding = [System.Text.Encoding]::UTF8
+$OutputEncoding = [System.Text.Encoding]::UTF8
+```
+
+Then run Python with UTF-8 mode:
+
+```powershell
+uv run python -X utf8 run_pipeline.py --brand Bosch --limit 10
+```
+
+For logs:
+
+```powershell
+mkdir logs
+$ts = Get-Date -Format "yyyyMMdd_HHmmss"
+uv run python -X utf8 run_pipeline.py --brand Bosch --limit 10 2>&1 | Tee-Object "logs/bosch_$ts.log"
+```
+
+## Recommended usage for teammates
+
+Backend developers should use:
+
+```text
+output_json/{Brand}/
+output_json/_index/manuals_index.json
+output_json/_index/fault_codes_index.json
+```
+
+Frontend/mobile developers should usually use:
+
+```text
+manuals_index.json for manual/library lists
+fault_codes_index.json for fault-code search
+full manual JSON files for detail views
+```
+
+Data pipeline developers should use:
+
+```text
+raw_pdfs/
+download_manuals.py
+run_pipeline.py
+source_registry.example.json
+schemas.py
+prompts/
+_review/
+_debug/
+```

+# A3Service Data Pipeline Output Guide
+
+## Purpose
+
+This document explains how backend, frontend, and mobile developers should use the JSON files generated by the A3Service data pipeline.
+
+The data pipeline converts manufacturer PDF manuals into structured JSON data. These JSON files are generated during development or build time. The mobile app should use the generated structured data offline and should not call an LLM at runtime for normal technician use.
+
+The main idea is simple:
+
+```text
+PDF manuals
+  -> data pipeline
+  -> structured JSON files
+  -> backend database or offline mobile data
+```
+
+## Output location
+
+Generated data is stored under:
+
+```text
+apps/data-pipeline/output_json/
+```
+
+Current output structure:
+
+```text
+output_json/
+  Bosch/
+    bosch_96-afue-condensing-gas-furnace_[hash].json
+
+  Vaillant/
+    vaillant_ecotec-plus_[hash].json
+
+  _index/
+    manuals_index.json
+    fault_codes_index.json
+    processed_manuals.json
+
+  _review/
+    low_confidence_records.json
+    failed_extractions.json
+
+  _debug/
+    raw and repaired extractor responses
+```
+
+## Important rule
+
+The full manual JSON files are the source of truth.
+
+Index files are helper files created from the full manual JSON files. They are useful for search, listing, and quick access, but they should be treated as derived data.
+
+```text
+Full manual JSON = source of truth
+Index JSON files = fast lookup files
+Review JSON files = quality control files
+Debug files = local developer troubleshooting files
+```
+
+## Full manual JSON files
+
+Brand folders contain the full extracted data for each processed manual.
+
+Example:
+
+```text
+output_json/Bosch/bosch_96-afue-condensing-gas-furnace_ddbe41d426.json
+```
+
+A full manual JSON file contains:
+
+```text
+schema_version
+document_meta
+technical_specs
+fault_codes
+diagnostic_codes
+status_codes
+safety_warnings
+maintenance_tasks
+search_terms
+derived_guidance
+extraction_meta
+```
+
+Backend developers should use full manual JSON files when importing data into the database.
+
+Frontend and mobile developers usually should not load full manual JSON files for search screens. They should first use index files, then open the full manual JSON only when detailed data is needed.
+
+## document_meta
+
+The `document_meta` object describes the manual itself.
+
+Example fields:
+
+```json
+{
+  "brand_name": "BOSCH",
+  "product_family": "96% AFUE Condensing Gas Furnace",
+  "model_names": [
+    "BGH96M060B3C",
+    "BGH96M080B3C"
+  ],
+  "manual_type": "installation_and_maintenance",
+  "document_title": "Installation and Operating Instructions 96% AFUE Condensing Gas Furnace Bosch BGH96 Model",
+  "document_code": "BTC 772003301 C",

+  "source_file": "bgh96_furnace_revc_iom_en_06.2025.pdf",
+  "file_hash": "ddbe41d426..."
+}
+```
+
+Use this data for:
+
+```text
+manual library pages
+brand and model filtering
+backend manual records
+source tracking
+```
+
+## technical_specs
+
+The `technical_specs` array contains extracted technical specifications.
+
+Example:
+
+```json
+{
+  "parameter": "Inlet Gas Supply Pressure (Natural Gas)",
+  "value": "Minimum: 4.5",
+  "unit": "in. WC",
+  "applies_to_models": [],
+  "category": "gas",

+      "table_title": "Table 24 Inlet Gas Supply Pressure",
+      "source_quote": "Natural Gas Minimum: 4.5 in. WC"
+    }
+  ],
+  "confidence": 1.0,
+  "review_required": false
+}
+```
+
+Use this data for:
+
+```text
+technical specification screens
+manual detail pages
+model comparison
+backend technical data tables
+```
+
+## fault_codes
+
+The `fault_codes` array contains detailed fault code information from the manual.
+
+Example:
+
+```json
+{
+  "code": "F9",
+  "description": "Pressure switch stuck open",
+  "possible_causes": [
+    "Pressure switch hose blocked, pinched or connected improperly",
+    "Blocked flue",
+    "Weak induced-draft blower"
+  ],
+  "manufacturer_steps": [
+    "Inspect pressure switch hose. Repair if necessary.",
+    "Inspect flue for blockage, proper length, elbows, and termination.",
+    "Replace pressure switch."
+  ],
+  "cautions_or_notes": [
+    "Turn power OFF prior to repair.",
+    "Replace pressure switch with proper replacement part."
+  ],
+  "symptoms": [],
+  "related_components": [
+    "Pressure switch",
+    "Induced draft blower",
+    "Flue"

+      "source_quote": "F9 Pressure switch stuck open"
+    }
+  ],
+  "confidence": 1.0,
+  "review_required": false
+}
+```
+
+Use this data for:
+
+```text
+fault code search
+fault detail pages
+technician troubleshooting screens
+backend fault code records
+offline mobile lookup
+```
+
+## diagnostic_codes
+
+The `diagnostic_codes` array contains diagnostic or installer-level codes if they exist in the manual.
+
+Example:
+
+```json
+{
+  "code": "d.000",
+  "description": "Heating partial load",
+  "value_range": "Auto, 0 to 24 kW",
+  "default_value": "Auto",
+  "unit": "kW",
+  "adjustable": true,
+  "source_refs": [
+    {
+      "page_number": 35,
+      "section_title": "Installer level overview",
+      "table_title": null,
+      "source_quote": "d.000 Heating partial load"
+    }
+  ],
+  "confidence": 1.0,
+  "review_required": false
+}
+```
+
+Use this data for:
+
+```text
+service menus
+installer settings
+advanced technician reference
+```
+
+Some manuals do not contain diagnostic codes. In that case this array may be empty.
+
+## status_codes
+
+The `status_codes` array contains status or operating codes.
+
+Example:
+
+```json
+{
+  "code": "01",
+  "meaning": "Heating",
+  "operating_mode": "heating",
+  "source_refs": [
+    {
+      "page_number": 74,
+      "section_title": null,
+      "table_title": "Operation code",
+      "source_quote": "01 Heating"
+    }
+  ],
+  "confidence": 1.0,
+  "review_required": false
+}
+```
+
+Use this data for:
+
+```text
+operating state reference
+service screens
+technician diagnostics
+```
+
+## safety_warnings
+
+The `safety_warnings` array contains warnings, cautions, dangers, notices, and important safety notes from the manual.
+
+Example:
+
+```json
+{
+  "warning_type": "warning",
+  "topic": "Fire or Explosion Hazard",
+  "text": "Do not store or use gasoline or other flammable vapors and liquids in the vicinity of this or any other appliance.",
+  "source_refs": [
+    {
+      "page_number": 4,
+      "section_title": "1.2 Safety",
+      "table_title": null,
+      "source_quote": "WARNING Fire or explosion hazard! Do not store or use gasoline..."
+    }
+  ],
+  "confidence": 1.0,
+  "review_required": false
+}
+```
+
+Use this data for:
+
+```text
+safety warning screens
+fault detail safety notes
+manual detail pages
+technician alerts
+```
+
+## maintenance_tasks
+
+The `maintenance_tasks` array contains maintenance or inspection tasks if the manual includes them.
+
+Example:
+
+```json
+{
+  "task_name": "Inspect condensate drain",
+  "description": "Check condensate drain line and trap for blockage.",
+  "interval": "Annually",
+  "required_qualification": "Qualified service technician",
+  "source_refs": [
+    {
+      "page_number": 62,
+      "section_title": "Maintenance",
+      "table_title": null,
+      "source_quote": "Inspect condensate drain..."
+    }
+  ],
+  "confidence": 1.0,
+  "review_required": false
+}
+```
+
+Some manuals may not produce maintenance tasks in the current extraction version.
+
+## source_refs
+
+Most extracted records include `source_refs`.
+
+A source reference shows where the extracted data came from.
+
+Example:
+
+```json
+{
+  "page_number": 74,
+  "section_title": null,
+  "table_title": "Error code Fault description",
+  "source_quote": "F9 Pressure switch stuck open"
+}
+```
+
+Use source references for:
+
+```text
+manual verification
+admin review
+showing source page in UI
+debugging bad extraction
+```
+
+Recommended frontend display:
+
+```text
+Source: Bosch manual, page 74
+```
+
+## confidence
+
+The `confidence` field is an extraction confidence score between `0.0` and `1.0`.
+
+Important: this is not a perfect scientific probability. It is a review-priority signal.
+
+Interpretation:
+
+```text
+1.0   very clear extraction
+0.8   probably correct, but still check if important
+0.5   uncertain
+0.0   missing, repaired, or unreliable metadata
+```
+
+Do not use confidence as the only truth criterion.
+
+Use it together with:
+
+```text
+review_required
+source_refs
+extraction_meta
+manual review status
+```
+
+## review_required
+
+The `review_required` field tells whether a record should be checked by a human before production use.
+
+A record may require review when:
+
+```text
+causes are missing
+manufacturer steps are missing
+source references are unclear
+the extracted value is ambiguous
+the JSON response was repaired
+the manual section was hard to interpret
+```
+
+Recommended behavior:
+
+```text
+Backend:
+  Store review_required in the database.
+
+Frontend/mobile:
+  Avoid showing review-required data as fully verified.
+  If shown, label it as unverified or needs review.
+
+Data engineer:
+  Use low_confidence_records.json to review and improve data.
+```
+
+## extraction_meta
+
+The `extraction_meta` object describes extraction quality for the full manual.
+
+Example:
+
+```json
+{
+  "overall_confidence": 0.82,
+  "review_required": true,
+  "missing_or_unclear_sections": [],
+  "extraction_notes": [
+    "Original Gemini response was malformed JSON and was repaired by the pipeline."
+  ]
+}
+```
+
+Use this data for:
+
+```text
+admin review
+dataset quality tracking
+debugging extraction problems
+deciding whether a manual is production-ready
+```
+
+## manuals_index.json
+
+Path:
+
+```text
+output_json/_index/manuals_index.json
+```
+
+Purpose:
+
+`manuals_index.json` is a summary list of all successfully processed manuals.
+
+It answers:
+
+```text
+Which manuals have been processed?
+Which brand and model does each manual belong to?
+Where is the full output JSON file?
+Does the manual need review?
+```
+
+Example:
+
+```json
+[
+  {
+    "source_file": "bgh96_furnace_revc_iom_en_06.2025.pdf",
+    "file_hash": "ddbe41d426...",
+    "output_file": "Bosch\\bosch_96-afue-condensing-gas-furnace_ddbe41d426.json",
+    "brand_name": "BOSCH",
+    "product_family": "96% AFUE Condensing Gas Furnace",
+    "model_names": [
+      "BGH96M060B3C",
+      "BGH96M080B3C"
+    ],

+## fault_codes_index.json
+
+Path:
+
+```text
+output_json/_index/fault_codes_index.json
+```
+
+Purpose:
+
+`fault_codes_index.json` is a flattened list of all extracted fault codes from all successfully processed manuals.
+
+If there are 100 manuals and all of them have fault codes, this file should contain fault codes from all 100 manuals.
+
+This file exists so the backend or mobile app can search fault codes quickly without opening every full manual JSON file.
+
+Each record includes:
+
+```text
+code
+description
+brand_name
+product_family
+model_names
+search_tags
+related_components
+output_file
+confidence
+review_required
+```
+
+Example:
+
+```json
+{
+  "code": "F9",
+  "description": "Pressure switch stuck open",
+  "brand_name": "BOSCH",
+  "product_family": "96% AFUE Condensing Gas Furnace",
+  "model_names": [
+    "BGH96M060B3C",
+    "BGH96M080B3C"
+  ],
+  "search_tags": [
+    "pressure switch",
+    "stuck open",
+    "venting"
+  ],
+  "related_components": [
+    "Pressure switch",
+    "Induced draft blower",
+    "Flue"
+  ],
+  "output_file": "Bosch\\bosch_96-afue-condensing-gas-furnace_ddbe41d426.json",
+  "confidence": 1.0,
+  "review_required": false
+}
+```
+
+Use this file for:
+
+```text
+search by fault code
+search by symptom or component
+list fault codes by brand
+list fault codes by model
+open the full manual JSON using output_file
+```
+
+Recommended search flow:
+
+```text
+1. User searches "pressure switch".
+2. App searches fault_codes_index.json.
+3. App finds F9 Pressure switch stuck open.
+4. App uses output_file to load the full manual JSON.
+5. App finds the complete F9 record in fault_codes.
+6. App displays causes, steps, warnings, and source references.
+```
+
+## processed_manuals.json
+
+Path:
+
+```text
+output_json/_index/processed_manuals.json
+```
+
+Purpose:
+
+`processed_manuals.json` is a pipeline state file.
+
+It helps the pipeline skip PDFs that were already processed.
+
+The pipeline calculates a file hash for each PDF. If the same hash already exists in `processed_manuals.json`, the pipeline skips the file unless `--force` is used.
+
+This file is mainly for the data pipeline, not for frontend or mobile.
+
+Use this file for:
+
+```text
+avoiding repeated Gemini API calls
+tracking processed PDF hashes
+debugging pipeline runs
+```
+
+## low_confidence_records.json
+
+Path:
+
+```text
+output_json/_review/low_confidence_records.json
+```
+
+Purpose:
+
+`low_confidence_records.json` collects records that need human review.
+
+A record may appear here when:
+
+```text
+confidence is low
+review_required is true
+causes are missing
+manufacturer steps are missing
+source reference is unclear
+JSON was repaired after malformed LLM output
+```
+
+Example:
+
+```json
+{
+  "section": "fault_codes",
+  "output_file": "Bosch\\bosch_96-afue-condensing-gas-furnace_ddbe41d426.json",
+  "confidence": 0.9,
+  "review_required": true,
+  "record": {
+    "code": "FE",
+    "description": "Gas valve not working",
+    "possible_causes": [],
+    "manufacturer_steps": [],
+    "related_components": [
+      "Gas valve"
+    ]
+  }
+}
+```
+
+Use this file for:
+
+```text
+human review
+quality control
+prioritizing manual corrections
+deciding which records are not production-ready
+```
+
+Frontend should not treat review-required records as fully verified.
+
+## failed_extractions.json
+
+Path:
+
+```text
+output_json/_review/failed_extractions.json
+```
+
+Purpose:
+
+`failed_extractions.json` tracks manuals that failed during extraction.
+
+Common reasons:
+
+```text
+Gemini 503 high demand
+invalid API key
+malformed response
+schema validation failure
+network error
+```
+
+Example:
+
+```json
+[
+  {
+    "source_file": "ecotec-plus-open-vent-installation-and-servicing-instructions-2914319.pdf",
+    "error": "503 UNAVAILABLE",
+    "failed_at": "2026-04-27T18:34:06.774997+00:00"
+  }
+]
+```
+
+Use this file for:
+
+```text
+data engineering troubleshooting
+retry planning
+pipeline monitoring
+```
+
+This file should not be used by the app.
+
+## _debug folder
+
+Path:
+
+```text
+output_json/_debug/
+```
+
+Purpose:
+
+The `_debug` folder stores raw Gemini responses, repaired responses, and validation errors.
+
+This folder is for local developer debugging only.
+
+Do not commit this folder.
+
+It should be ignored in `.gitignore`:
+
+```gitignore
+apps/data-pipeline/output_json/_debug/
+```
+
+## Recommended backend import strategy
+
+Backend should import full manual JSONs into normalized database tables.
+
+Suggested tables:
+
+```text
+manuals
+models
+fault_codes
+fault_code_causes
+fault_code_steps
+fault_code_notes
+fault_code_source_refs
+technical_specs
+status_codes
+diagnostic_codes
+safety_warnings
+maintenance_tasks
+```
+
+Suggested relationships:
+
+```text
+manuals 1..* models
+manuals 1..* fault_codes
+fault_codes 1..* possible_causes
+fault_codes 1..* manufacturer_steps
+fault_codes 1..* source_refs
+manuals 1..* technical_specs
+manuals 1..* safety_warnings
+manuals 1..* status_codes
+manuals 1..* diagnostic_codes
+```
+
+Possible database mapping:
+
+```text
+document_meta -> manuals table
+document_meta.model_names -> models table
+fault_codes -> fault_codes table
+fault_codes.possible_causes -> fault_code_causes table
+fault_codes.manufacturer_steps -> fault_code_steps table
+fault_codes.cautions_or_notes -> fault_code_notes table
+fault_codes.source_refs -> fault_code_source_refs table
+technical_specs -> technical_specs table
+status_codes -> status_codes table
+diagnostic_codes -> diagnostic_codes table
+safety_warnings -> safety_warnings table
+```
+
+## Recommended frontend and mobile usage
+
+For search screens:
+
+```text
+Use fault_codes_index.json.
+```
+
+For manual library screens:
+
+```text
+Use manuals_index.json.
+```
+
+For detail screens:
+
+```text
+Use output_file from the index record.
+Load the full manual JSON.
+Find the matching fault code, status code, or technical spec.
+Display full details.
+```
+
+Example fault code detail screen should show:
+
+```text
+code
+description
+possible causes
+manufacturer steps
+cautions or notes
+related components
+severity
+safety level
+source page
+review status
+```
+
+## Minimal demo strategy
+
+For a quick demo, the backend or frontend can use JSON files directly without database import.
+
+Demo flow:
+
+```text
+1. Load manuals_index.json.
+2. Show available brands and manuals.
+3. Load fault_codes_index.json.
+4. Search by code, description, search_tags, or related_components.
+5. Show matching fault codes.
+6. Open the matching full manual JSON using output_file.
+7. Display full fault details.
+```
+
+This allows the team to demonstrate offline technical lookup before the database integration is complete.
+
+## Runtime LLM usage
+
+The mobile app should not call Gemini or another LLM at runtime for normal technician use.
+
+Correct architecture:
+
+```text
+LLM used during data generation
+Generated JSON used by backend/mobile
+Mobile app works offline
+```
+
+Incorrect architecture:
+
+```text
+Technician asks question
+Mobile app calls LLM every time
+Technician waits for online answer
+```
+
+The second approach is not suitable for the offline-first goal.
+
+## Future derived guidance
+
+The current pipeline extracts manufacturer-stated information.
+
+Later, the project may generate technician-friendly guidance from:
+
+```text
+extracted JSON
+manual source references
+domain rules
+reviewed technician knowledge
+optional LLM generation
+```
+
+This generated guidance must be stored separately from manufacturer facts.
+
+The schema already has a placeholder:
+
+```json
+{
+  "derived_guidance": {
+    "status": "not_generated",
+    "technician_summary": null,
+    "steps": [],
+    "generated_from": [],
+    "review_status": "not_reviewed"
+  }
+}
+```
+
+Do not mix generated repair advice with manufacturer-stated data unless it is clearly marked as derived guidance.
+
+## Reliability rules
+
+The data is extracted from manufacturer manuals by an LLM-assisted pipeline.
+
+Do not treat every extracted field as final truth without review.
+
+Use these fields:
+
+```text
+confidence
+review_required
+source_refs
+extraction_meta
+```
+
+Recommended rules:
+
+```text
+If review_required is false and source_refs exist:
+  The record is probably safe for demo use.
+
+If review_required is true:
+  The record should be reviewed before production use.
+
+If source_refs are missing:
+  The record should be treated as weaker.
+
+If extraction_meta.review_required is true:
+  The whole manual output should be reviewed before production use.
+
+If JSON was repaired:
+  The manual output should be reviewed even if many individual records look good.

+# A3Service Data Pipeline Requirements
+
+## Purpose
+
+The data pipeline converts boiler and HVAC manufacturer manuals into structured JSON data that can later be ingested by the backend and used by the mobile app's offline technical library.
+
+The pipeline is used at development/build time, not at app runtime. The mobile application should not depend on live LLM calls for field use because the product is designed around offline access to technical documentation and fault information.
+
+## Current scope
+
+The pipeline should extract structured information from PDF manuals placed locally under:
+

The following steps shall be followed for each appliance connected to the venting system being placed into operation, while all other appliances connected to the venting system are not in operation: 1. Inspect the venting system for proper size and horizontal pitch. Determine that there is no blockage, restriction, leakage, corrosion or other deficiencies which could cause an unsafe condition. 2. Close all building doors and windows and all doors. 3. Turn on clothes dryers and TURN ON any exhaust fans, such as range hoods and bathroom exhausts, so they shall operate at maximum speed. Open the fireplace damper. Do not operate a summer exhaust fan. 4. Follow the lighting instructions. Place the appliance being inspected in operation. Adjust thermostat so the appliance shall operate continuously. 5. Test each appliance (such as a water heater) equipped with a draft hood for spillage (down-draft or no draft) at the draft hood relief opening after 5 minutes of main burner operation. Appliances that do not have draft hoods need to be checked at the vent pipe as close to the appliance as possible. Use a combustion analyzer to check the CO2 and CO levels of each appliance. Use a draft gauge to check for a downdraft or inadequate draft condition. 6. After it has been determined that each appliance properly vents when tested as outlined above, return doors, windows, exhaust fans, fireplace dampers and any other gas burning appliance to their normal condition. 7. If improper venting is observed during any of the above tests, a problem exists with either the venting system or the appliance does not have enough combustion air (Supply Air from outside) to complete combustion. This condition must be corrected before the appliance can function safely. NOTE: An unsafe condition exists when the CO reading exceeds 40 ppm and the draft reading is not in excess of -0.1 in. W.C.(-25 kPa) with all of the appliance(s) operating at the same time. 8. Any corrections to the venting system and / or to the supply (outside) air system must be in accordance with the National Fuel Gas Code Z223.1 or CAN/CGA B149.1 Natural Gas and Propane Installation Code (latest editions).

The following steps shall be followed for each appliance connected to the venting system being placed into operation, while all other appliances connected to the venting system are not in operation: 1. Inspect the venting system for proper size and horizontal pitch. Determine that there is no blockage, restriction, leakage, corrosion or other deficiencies which could cause an unsafe condition. 2. Close all building doors and windows and all doors. 3. Turn on clothes dryers and TURN ON any exhaust fans, such as range hoods and bathroom exhausts, so they shall operate at maximum speed. Open the fireplace damper. Do not operate a summer exhaust fan. 4. Follow the lighting instructions. Place the appliance being inspected in operation. Adjust thermostat so the appliance shall operate continuously. 5. Test each appliance (such as a water heater) equipped with a draft hood for spillage (down-draft or no draft) at the draft hood relief opening after 5 minutes of main burner operation. Appliances that do not have draft hoods need to be checked at the vent pipe as close to the appliance as possible. Use a combustion analyzer to check the CO2 and CO levels of each appliance. Use a draft gauge to check for a downdraft or inadequate draft condition. 6. After it has been determined that each appliance properly vents when tested as outlined above, return doors, windows, exhaust fans, fireplace dampers and any other gas burning appliance to their normal condition. 7. If improper venting is observed during any of the above tests, a problem exists with either the venting system or the appliance does not have enough combustion air (Supply Air from outside) to complete combustion. This condition must be corrected before the appliance can function safely. NOTE: An unsafe condition exists when the CO reading exceeds 40 ppm and the draft reading is not in excess of -0.1 in. W.C.(-25 kPa) with all of the appliance(s) operating at the same time. 8. Any corrections to the venting system and / or the supply (outside) air system must be in accordance with the National Fuel Gas Code Z223.1 or CAN/CGA B149.1 Natural Gas and Propane Installation Code (latest editions). If the vent system must be resized, follow the appropriate tables in Appendix G of the above codes or for this appliance.",

Open the fireplace damper. Do not operate a summer exhaust fan. 4. Follow the lighting instructions. Place the appliance being inspected in operation. Adjust thermostat so the appliance shall operate continuously. 5. Test each appliance (such as a water heater) equipped with a draft hood for spillage (down-draft or no draft) at the draft hood relief opening after 5 minutes of main burner operation. Appliances that do not have draft hoods need to be checked at the vent pipe as close to the appliance as possible. Use a combustion analyzer to check the CO2 and CO levels of each appliance. Use a draft gauge to check for a downdraft or inadequate draft condition. 6. After it has been determined that each appliance properly vents when tested as outlined above, return doors, windows, exhaust fans, fireplace dampers and any other gas burning appliance to their normal condition. 7. If improper venting is observed during any of the above tests, a problem exists with either the venting system or the appliance does not have enough combustion air (Supply Air from outside) to complete combustion. This condition must be corrected before the appliance can function safely. NOTE: An unsafe condition exists when the CO reading exceeds 40 ppm and the draft reading is not in excess of -0.1 in. W.C.(-25 kPa) with all of the appliance(s) operating at the same time. 8. Any corrections to the venting system and / or to the supply (outside) air system must be in accordance with the National Fuel Gas Code Z223.1 or CAN/CGA B149.1 Natural Gas and Propane Installation Code (latest editions). If the vent system must be resized, follow the appropriate tables in Appendix G of the above codes or for this appliance.",

Rinse out burner rods with a water jet; hold burner so water enters all slots if the burner rods and drains out again. 8. Remove remaining water by swinging the burner. 9. Check that the slots of the burner rods are free. Remove water and dirt residue in the slots. If any slots are damaged the burner must be replaced. 10. Assemble and install the burner in reverse order of removal and disassembly (→ page 46). Tighten the fixing nuts well. Make sure that the front edge of the burner box cover is properly engaged in the sealing grommets. 11. Place boiler in operation as directed in (→ Chapter 9.1, page 33). 12. Check operation of AquaSmart. 13. Test low water cut-off if installed. 14. Check area around boiler for hazards. The area around the boiler must be free from flammable substances, gasoline or any other flammable or corrosive vapors and liquids."

+You are an expert technical data extraction assistant for HVAC and boiler manuals.
+
+Your task is to extract structured manufacturer-stated information from the provided PDF manual.
+
+You must output JSON that strictly follows the provided schema.
+
+PRIORITY ORDER
+
+Prioritize extraction in this order:
+
+1. document metadata
+2. fault codes and troubleshooting charts
+3. diagnostic codes
+4. status codes
+5. safety warnings
+6. maintenance tasks
+7. core technical specifications
+
+Core technical specifications include model names, fuel/gas type, heat input/output, electrical data, dimensions, pressure limits, water flow, and connection sizes.
+
+Do not extract every installation clearance table, flue terminal positioning table, airflow CFM table, or large generic installation table unless it is directly relevant to fault diagnosis, servicing, or model identification.
+
+CRITICAL RULES
+
+1. NO HALLUCINATIONS
+Only extract information explicitly present in the manual. Do not invent fault codes, causes, repair steps, technical values, safety warnings, or model names.
+
+2. PRESERVE UNCERTAINTY
+If a value is missing, unclear, unreadable, or ambiguous, leave the field empty or null where allowed and set review_required to true.
+
+3. MANUFACTURER FACTS ONLY
+Do not generate technician-friendly repair advice unless it is directly stated in the manual.
+The derived_guidance object must remain:
+status = "not_generated"
+technician_summary = null
+steps = []
+generated_from = []
+review_status = "not_reviewed"
+
+4. SOURCE REFERENCES
+For each important extracted item, provide source_refs when possible.
+Include page_number, section_title, table_title, and a short source_quote when visible.
+If page number is not reliably available, set page_number to null.
+
+5. CONFIDENCE SCORES
+Every extracted technical item must include confidence between 0.0 and 1.0.
+Use lower confidence when:
+- the text is ambiguous
+- table structure is hard to interpret
+- the value may apply only to some models
+- the source does not clearly connect a cause or step to a specific code
+
+6. REVIEW REQUIRED
+Set review_required to true when:
+- the item may be incomplete
+- the item was extracted from a complex table
+- the manual gives only partial information
+- the record is useful but uncertain
+- a code has description but no causes or actions
+- a model mapping is unclear
+
+7. EXTRACT BROAD MANUAL DATA
+Extract the following when present:
+- document metadata
+- model names and product family
+- technical specifications
+- fault codes
+- diagnostic codes
+- status codes
+- safety warnings
+- maintenance tasks
+- search terms useful for offline search
+
+8. FAULT CODE EXTRACTION
+For each fault code, extract:
+- exact code
+- description
+- possible causes, only if stated
+- manufacturer troubleshooting/corrective steps, only if stated
+- cautions or notes
+- symptoms
+- related components
+- search tags
+
+If a manual has corrective actions but no separate "possible cause" column, put the repair actions in manufacturer_steps and leave possible_causes empty.
+
+9. TECHNICAL SPECIFICATIONS
+For technical specifications, preserve units and values exactly.
+If a value applies to multiple models, include applies_to_models.
+If the model mapping is unclear, leave applies_to_models empty and set review_required to true.
+
+10. SAFETY
+Safety warnings must be extracted carefully.
+Do not simplify dangerous safety instructions in a way that changes meaning.
+
+11. OUTPUT LANGUAGE
+Keep extracted manufacturer text in the source language of the manual.
+Do not translate to Bosnian in this extraction step.
+
+Now analyze the full PDF manual and produce the JSON according to the schema.

-## BEFORE START
-This project uses uv instead of pip.
-model : qwen
-
-## Instructions
-1 - First download uv. This site has instructions, you just need to copy paste onto the bash.
-
-https://docs.astral.sh/uv/getting-started/installation/
-
-2 - After uv install, only thing left is go "cd data-pipeline" then "uv sync"

-You are an expert technical data extraction assistant. Your task is to extract fault codes, their descriptions, related troubleshooting steps, and technical specifications from the provided HVAC or thermal appliance manual (e.g., boilers, water heaters).
-
-CRITICAL RULES:
-1. NO HALLUCINATIONS: You must ONLY extract information explicitly stated in the provided text. Do not invent, guess, or infer any fault codes, descriptions, or solutions.
-2. MISSING DATA: If a specific piece of information (like a troubleshooting step or possible cause) is not mentioned for a fault code, leave that array empty. Do not fill it with generic advice.
-3. ACCURACY: Ensure the exact alphanumeric fault code (e.g., F.22, EA) is captured perfectly.
-4. FORMAT: You must format your output strictly according to the provided JSON schema. 
-
-Analyze the text carefully and extract the data now.

+# Backend DB bootstrap and seed (Sprint 1)
+
+This guide documents the Prisma migrate/generate/seed flow for a fresh clone.
+
+## Prereqs
+
+- Node.js 22+ and npm 10+
+- A local PostgreSQL instance
+- A repo root .env file with the required database URLs
+
+## Required environment variables
+
+Create a .env file at the repo root (c:\A3Service\.env) with:
+
+```
+DATABASE_URL=postgresql://USER:PASSWORD@HOST:PORT/DBNAME?schema=public
+DIRECT_URL=postgresql://USER:PASSWORD@HOST:PORT/DBNAME?schema=public
+```
+
+Notes:
+- DATABASE_URL is used by Prisma Client at runtime.
+- DIRECT_URL is used by Prisma Migrate.
+- Both must be valid URLs or seed/migrate will fail.
+
+## One-time setup (fresh clone)
+
+From the repo root:
+
+1) Install dependencies
+
+```
+npm install
+```
+
+2) Generate Prisma client
+
+```
+npm run prisma:generate
+```
+
+3) Apply migrations (dev database)
+
+```
+npm run prisma:migrate:dev
+```
+
+4) Seed the database
+
+```
+npm run prisma:seed
+```
+
+## What seed creates
+
+The seed file lives at apps/api/prisma/seed.ts and inserts:
+- Users and profiles (manager and technicians)
+- Clients and sites
+- Jobs with realistic dates
+- Service logs (Sprint 2 stub data)
+- Sync logs
+
+## Quick verification
+
+After seeding, you should be able to:
+- Log in using a seeded user (see apps/api/prisma/seed.ts)
+- Query jobs endpoints and see sample data
+
+## Troubleshooting
+
+- If migrate hangs, confirm .env exists and DATABASE_URL is valid.
+- If seed fails, ensure DIRECT_URL is set and postgres is reachable.
+- If Prisma Client is stale, re-run `npm run prisma:generate`.
