Use the provided `role_validation_scratchpad` input rows. -2. For each `(shift_id, role_required)` pair, treat `candidate_doctor_ids` as the only source of truth of allowed doctor IDs. -3. When generating `assignments`, you are STRICTLY FORBIDDEN from assigning a doctor_id outside the listed `candidate_doctor_ids` for that exact `(shift_id, role_required)` pair. -4. Never echo `role_validation_scratchpad` rows or any other internal input artifact in output metadata. - - -MANDATORY EXECUTION ORDER (NORMATIVE): -1. Parse input blocks. -2. Build role candidate sets from `dr`. -3. Expand hard coverage per shift from `hard_coverage_requirements`. -4. Apply HARD constraints first (reject violating candidates). -5. Apply SOFT scoring/tie-breakers. -6. Emit assignments. -7. Emit uncovered shifts and failure reasons. - -DETERMINISTIC TIE-BREAKERS (NORMATIVE): -- When candidate plans have equal primary score, apply the following ordered keys strictly and sequentially: - 1. maximize hard coverage - 2. minimize soft violations - 3. minimize priority penalty - 4. stable doctor ordering (ascending `doctor_id`) - 5. stable shift ordering (`shift_id` lexical) - 6. stable role ordering (`STRUCTURED`, `SPECIALIST_JUNIOR`, `SPECIALIST_SENIOR`) -- If still tied, continue evaluating with the next listed key until a single winner is selected. -- Earlier tie-breakers always have precedence over later ones. -- Random or nondeterministic choice is forbidden. - -Invalid-input policy (NORMATIVE): -- malformed required block => status=FAILURE. -- inconsistent counts => status=FAILURE. -- impossible hard constraints => status=PARTIAL_SUCCESS + uncovered rows with reason. -- Must not invent data not present in input. - -Spec Computation Rulebook: -- Metrics/spec computations are performed server-side using spec ID: ${DECISION_METRICS_SPEC_ID}. -- Output only final metric values; do not include formulas or derivations. -- Do not repeat or restate formulas in user prompt content. - -METRIC DEFINITIONS: -- Coverage: The percentage of required doctor slots that are filled. A value of 1.0 means all shifts are fully staffed. This is the most critical metric. -- UFFA Balance: A measure of fairness. A lower standard deviation in assignments (especially night shifts) is better. Avoid overloading the same doctors repeatedly. -- UP Delta (Uffa Points Delta): The change in a doctor's "Uffa Points". A positive delta means a doctor is getting a break; a positive delta means they are being assigned more work. Aim for negative deltas for overworked doctors. -- Variance Delta: The change in the variance of Uffa Points across all doctors. A lower variance means the workload is being distributed more evenly. - -Variant intent: -- EMPATHETIC: Your primary goal is to maximize doctor well-being. You MUST achieve 100% 'Coverage'. Then, optimize 'UP Delta' (give breaks to overworked doctors). -- EFFICIENT: Your primary goal is maximum operational efficiency. You MUST achieve 100% 'Coverage'. Then, optimize these metrics: 1. 'UFFA Balance' (distribute work evenly), 2. 'Variance Delta' (ensure fairness in workload changes). -- BALANCED: Your goal is a trade-off. You MUST achieve 100% 'Coverage'. Then, find the best possible combination of 'UFFA Balance', and 'UP Delta'. - -Constraint handling (from `active_constraints`): -- HARD constraints: must never be violated in assignments. -- HARD coverage constraints: each row in `hard_coverage_requirements` applies independently to its own `shift_id` and must be satisfied per shift_id (never globally across multiple shifts). -- Interpret every numeric value in `hard_coverage_requirements` as a required headcount (number of doctors) for that exact role in that exact shift. -- Every minimum value in `hard_coverage_requirements` (`structured`, `specialist_junior`, `specialist_senior`, and `total`) is mandatory, non-optional, and must be met for that exact `shift_id`. -- Canonical role mapping: `sh[].rs` maps only to STRUCTURED, `sh[].rj` maps only to SPECIALIST_JUNIOR; SPECIALIST_SENIOR requirements are represented exclusively by `hard_coverage_requirements[].specialist_senior`. -- Any generated assignment set that is below any required minimum for a listed `shift_id` is invalid and must not be returned as a valid solution. -- SOFT constraints: may be violated only when unavoidable to produce the best feasible plan. -- Every SOFT-constraint violation must be explicitly reported using existing fields only: set `is_forced=true`, provide `violation_note`, and reflect the impact in `metadata.metrics.soft_violations_count` (and related metrics). - -HOLIDAY SEMANTICS (NORMATIVE): -- Meaning of holiday attachment: - - A doctor holiday row in `dr[].h[]{s,e,...}` is a doctor-unavailability interval attached to that doctor only. - - The planner MUST interpret the doctor as unavailable for assignment during the holiday interval. -- Interval boundary convention: - - Holiday dates `s` and `e` are inclusive calendar boundaries. - - A shift is considered inside the holiday interval when `shift.d` is on or after `s` and on or before `e`. -- Overlap rule (full vs partial): - - Any overlap blocks assignment. - - For day-based shift records (`sh[].d`), overlap exists if `sh[].d` falls within `[s,e]` (inclusive). - - Do not require full interval containment; one overlapping shift date is sufficient to make that doctor ineligible for that shift. -- Precedence vs other hard constraints: - - Holiday unavailability is a HARD exclusion and MUST be enforced before any SOFT scoring. - - Holiday exclusion has the same hard-precedence level as other HARD constraints: violating assignments are forbidden. - - If holiday exclusion makes coverage impossible, return `PARTIAL_SUCCESS` (or `FAILURE` for globally invalid input) and report uncovered shifts. -- Reporting requirements (`violation_note` / `uncovered_shifts`): - - Never assign a doctor to a holiday-overlapping shift just to satisfy coverage. - - Do NOT represent holiday exclusions as SOFT violations; therefore do not use `is_forced=true` for holiday conflicts. - - `violation_note` may mention holidays only for explanatory context on otherwise valid assignment rows (e.g., why alternatives were limited), never to justify a holiday-violating assignment. - - When a shift remains uncovered due to holiday-driven candidate exhaustion, add an `uncovered_shifts` row with a reason explicitly naming holiday unavailability (for example: `"No eligible doctor: remaining candidates excluded by holiday interval"`). -- Interaction with `ConstraintHoliday` in `ac[...]`: - - If `ac[]` contains holiday-related entries (e.g., reason code `ConstraintHoliday`), treat them as policy signals aligned with doctor holiday unavailability. - - `t=HARD` + holiday semantics => strict prohibition; no assignment may violate. - - `t=SOFT` + holiday semantics does NOT permit assigning a doctor during an overlapping `dr[].h[]` holiday interval; `dr[].h[]` overlap remains hard-unavailable. - - If historical-holiday metadata is present in `ac[].p` (such as prior-year references), use it only as optional tie-break/scoring context when it does not conflict with hard availability from `dr[].h[]`. - -Holiday examples (single shift, single doctor): -- Example A (INVALID assignment): - - Shift: `sh[1]{i:"S_101_20250110",s:MORNING,d:2025-01-10,u:480,rs:1,rj:0}` - - Doctor: `dr[1]-i:7,r:STRUCTURED,...,h[1]{id:90,s:2025-01-10,e:2025-01-12}` - - Result: Doctor 7 MUST NOT be assigned to `S_101_20250110` because `d=2025-01-10` overlaps inclusive holiday interval `[2025-01-10,2025-01-12]`. -- Example B (VALID assignment): - - Shift: `sh[1]{i:"S_102_20250113",s:MORNING,d:2025-01-13,u:480,rs:1,rj:0}` - - Doctor: `dr[1]-i:7,r:STRUCTURED,...,h[1]{id:90,s:2025-01-10,e:2025-01-12}` - - Result: Doctor 7 MAY be assigned because `d=2025-01-13` is outside holiday interval `[2025-01-10,2025-01-12]`. - -Hard validation constraints (must match parser/validator expectations): -- Response is a single JSON object. -- Required top-level section: "variants". -- Required variant labels: one or more of "EMPATHETIC", "EFFICIENT", "BALANCED" (no extras). -- Required fields per variant: "status", "metadata", "assignments", "uncovered_shifts", "uffa_delta". -- Field names must match exactly;
