ADDED Requirements

Requirement: Hold Overview API SHALL provide summary statistics

The API SHALL return aggregated summary KPIs for hold lots.

Scenario: Summary endpoint delegates to extended get_hold_detail_summary

• WHEN GET /api/hold-overview/summary is called with hold_type=quality
• THEN the route SHALL delegate to the extended get_hold_detail_summary(reason=None, hold_type='quality')
• THEN the response SHALL return { success: true, data: { totalLots, totalQty, workcenterCount, avgAge, maxAge, dataUpdateDate } }
• THEN only lots with EQUIPMENTCOUNT=0 AND CURRENTHOLDCOUNT>0 SHALL be included
• THEN hold_type classification SHALL use the same NON_QUALITY_HOLD_REASONS set as existing hold endpoints

Scenario: Summary with reason filter

• WHEN GET /api/hold-overview/summary?hold_type=quality&reason=品質確認 is called
• THEN the response SHALL only include lots where HOLDREASONNAME equals the specified reason

Scenario: Summary hold_type=all

• WHEN GET /api/hold-overview/summary?hold_type=all is called
• THEN the response SHALL include both quality and non-quality hold lots

Scenario: Summary error

• WHEN the database query fails
• THEN the response SHALL return { success: false, error: '查詢失敗' } with HTTP 500

Requirement: Hold Overview API SHALL provide workcenter x package matrix

The API SHALL return a cross-tabulation of workcenters and packages for hold lots.

Scenario: Matrix endpoint

• WHEN GET /api/hold-overview/matrix is called with hold_type=quality
• THEN the response SHALL return the same matrix structure as /api/wip/overview/matrix: { workcenters, packages, matrix, workcenter_totals, package_totals, grand_total }
• THEN workcenters SHALL be sorted by WORKCENTERSEQUENCE_GROUP
• THEN packages SHALL be sorted by total QTY descending
• THEN only HOLD status lots matching the hold_type SHALL be included

Scenario: Matrix delegates to existing get_wip_matrix

• WHEN the matrix endpoint is called
• THEN it SHALL delegate to get_wip_matrix(status='HOLD', hold_type=...) from wip_service.py

Scenario: Matrix with reason filter

• WHEN GET /api/hold-overview/matrix?hold_type=quality&reason=品質確認 is called
• THEN the matrix SHALL only include lots where HOLDREASONNAME equals the specified reason

Requirement: Hold Overview API SHALL provide TreeMap aggregation data

The API SHALL return aggregated data suitable for TreeMap visualization.

Scenario: TreeMap endpoint uses new get_hold_overview_treemap function

• WHEN GET /api/hold-overview/treemap is called with hold_type=quality
• THEN the route SHALL delegate to get_hold_overview_treemap() (the only new service function)
• THEN the response SHALL return { success: true, data: { items: [...] } }
• THEN each item SHALL contain { workcenter, reason, lots, qty, avgAge }
• THEN items SHALL be grouped by (WORKCENTER_GROUP, HOLDREASONNAME)
• THEN avgAge SHALL be calculated using the pre-computed AGEBYDAYS column from DW_MES_LOT_V

Scenario: TreeMap with matrix filter

• WHEN GET /api/hold-overview/treemap?hold_type=quality&workcenter=WC-MOLD&package=PKG-A is called
• THEN the response SHALL only include lots matching the workcenter AND package filters

Scenario: TreeMap with reason filter

• WHEN GET /api/hold-overview/treemap?hold_type=quality&reason=品質確認 is called
• THEN the response SHALL only include lots where HOLDREASONNAME equals the specified reason

Scenario: TreeMap empty result

• WHEN no hold lots match the filters
• THEN the response SHALL return { success: true, data: { items: [] } }

Requirement: Hold Overview API SHALL provide paginated lot details

The API SHALL return a paginated list of hold lot details.

Scenario: Lots endpoint delegates to extended get_hold_detail_lots

• WHEN GET /api/hold-overview/lots?hold_type=quality&page=1&per_page=50 is called
• THEN the route SHALL delegate to the extended get_hold_detail_lots(reason=None, hold_type='quality', ...)
• THEN the response SHALL return { success: true, data: { lots: [...], pagination: { page, perPage, total, totalPages } } }
• THEN each lot SHALL contain: lotId, workorder, qty, package, workcenter, holdReason, age, holdBy, dept, holdComment
• THEN lots SHALL be sorted by age descending (longest hold first)

Scenario: Lots with matrix filter

• WHEN GET /api/hold-overview/lots?hold_type=quality&workcenter=WC-MOLD&package=PKG-A is called
• THEN only lots matching the workcenter AND package filters SHALL be returned

Scenario: Lots with treemap filter

• WHEN GET /api/hold-overview/lots?hold_type=quality&workcenter=WC-MOLD&treemap_reason=品質確認 is called
• THEN only lots matching the workcenter AND treemap_reason SHALL be returned

Scenario: Lots with all filters combined

• WHEN GET /api/hold-overview/lots?hold_type=quality&reason=品質確認&workcenter=WC-MOLD&package=PKG-A&treemap_reason=品質確認 is called
• THEN all filters SHALL be applied as AND conditions

Scenario: Lots pagination bounds

• WHEN page is less than 1
• THEN page SHALL be treated as 1
• WHEN per_page exceeds 200
• THEN per_page SHALL be capped at 200

Scenario: Lots error

• WHEN the database query fails
• THEN the response SHALL return { success: false, error: '查詢失敗' } with HTTP 500

Requirement: Hold Overview API SHALL apply rate limiting

The API SHALL apply rate limiting to expensive endpoints.

Scenario: Rate limit on lots endpoint

• WHEN the lots endpoint receives excessive requests
• THEN rate limiting SHALL be applied using configured_rate_limit with a default of 90 requests per 60 seconds

Scenario: Rate limit on matrix endpoint

• WHEN the matrix endpoint receives excessive requests
• THEN rate limiting SHALL be applied using configured_rate_limit with a default of 120 requests per 60 seconds

Requirement: Hold Overview page route SHALL serve static Vite HTML

The Flask route SHALL serve the pre-built Vite HTML file.

Scenario: Page route

• WHEN user navigates to /hold-overview
• THEN Flask SHALL serve the pre-built HTML file from static/dist/hold-overview.html via send_from_directory
• THEN the HTML SHALL NOT pass through Jinja2 template rendering

Scenario: Fallback HTML

• WHEN the pre-built HTML file does not exist
• THEN Flask SHALL return a minimal HTML page with the correct script tag and module import

Requirement: Extended service functions SHALL maintain backward compatibility

The extended get_hold_detail_summary(), get_hold_detail_lots(), and get_wip_matrix() SHALL not break existing callers.

Scenario: Hold Detail summary backward compatibility

• WHEN existing Hold Detail code calls get_hold_detail_summary(reason='xxx')
• THEN the result SHALL be identical to the pre-extension behavior
• THEN the new hold_type parameter SHALL default to None (no additional filtering)

Scenario: Hold Detail lots backward compatibility

• WHEN existing Hold Detail code calls get_hold_detail_lots(reason='xxx', workcenter=..., package=..., age_range=...)
• THEN the result SHALL be identical to the pre-extension behavior
• THEN the new hold_type and treemap_reason parameters SHALL default to None

Scenario: WIP Overview matrix backward compatibility

• WHEN existing WIP Overview code calls get_wip_matrix(status='HOLD', hold_type='quality')
• THEN the result SHALL be identical to the pre-extension behavior
• THEN the new reason parameter SHALL default to None (no HOLDREASONNAME filtering)
