"""PROC-01 generator — Boréal Fenestration Inc. (Procurement): evaluation of five supplier quotations for RFQ BFI-2025-117
(annual supply of aluminium extrusion profiles).

Usage: python generate.py [--seed 4209] [--oracle-root ~/wp42-oracles]
Writes the PUBLIC bundle (inputs/, portal/portal.json, task.json, BRIEF.md) next to this file and the HIDDEN oracle
(oracle.json, REFERENCE.md) under <oracle-root>/PROC-01/.

Design note: the commercial figures (unit prices, quantities, terms) are design constants so that the planted ranking flip
(supplier C wins with its erroneous extensions, supplier B wins once corrected) is exact; the seed drives identifiers
(quotation numbers, certificate numbers, phone numbers, portal credentials, employee numbers).

Boréal Fenestration Inc. — Procurement · Approved by {ORG['manager']}, {ORG['manager_title']} · {RFQ_ISSUE.isoformat()}

## 1. Compliance screening (pass / fail)
A quotation is **compliant** only if it meets every mandatory requirement of the RFQ:

| # | Requirement | Source |
|---|---|---|
| M1 | Quotes all four SKUs in alloy 6063-T5 (Annex A) | RFQ §2, §3 |
| M2 | Lead time of at most {MAX_LEAD_DAYS} calendar days from PO release to delivery in Gatineau | RFQ §3 |
| M3 | Delivery to Gatineau: DDP, or EXW/FCA with the Annex B freight allowance added by BFI | RFQ §4 |
| M4 | Currency CAD or USD (USD converted at the RFQ rate of 1 USD = {FX_USD_CAD:.2f} CAD) | RFQ §4 |

Non-compliant quotations are **excluded from the award**: they receive a weighted score of 0, are shown in the evaluation
workbook with the reason for exclusion, and are not used to determine the lowest cost in criterion C1.

**Quotation validity.** The RFQ requires {VALIDITY_REQUIRED_DAYS} days of validity. A quotation whose stated validity has lapsed
on the evaluation date is *not* excluded: it is evaluated as submitted, the lapse is reported in the recommendation memo, and
any award recommendation involving that supplier is made **conditional on the supplier's written re-confirmation of its price
and terms** before the award. The evaluator records the re-confirmation as an open question for the Procurement Manager.

**Arithmetic.** The evaluator recomputes every extended amount (unit price × RFQ quantity) and every total. Where a quotation's
stated amounts do not tie, the evaluation uses the **unit prices** as the binding figures (RFQ §2: prices are per linear metre),
the corrected amounts are used for scoring, and the discrepancy is reported in the memo.

## 2. Normalisation to total landed cost (CAD)
`Total landed cost (CAD) = Σ (unit price × RFQ annual quantity) × FX + freight allowance`

* FX = 1.00 for CAD quotations; FX = {FX_USD_CAD:.2f} for USD quotations (RFQ rate).
* Freight allowance = 0 for DDP quotations; Annex B amount for EXW/FCA quotations, by origin.
* Pre-tax amounts only.

## 3. Weighted scoring (compliant quotations)
| Code | Criterion | Weight | Scoring scale |
|---|---|---|---|
| C1 | Total landed cost (CAD) | 50 % | score = (lowest compliant landed cost ÷ supplier's landed cost) × 100 |
| C2 | Lead time | 15 % | ≤ 7 days: 100 · 8–14 days: 85 · 15–21 days: 70 · > 21 days: non-compliant (M2) |
| C3 | Quality certification (ISO 9001:2015) | 10 % | valid certificate with number and expiry: 100 · certification in progress (audit scheduled): 50 · none: 0 |
| C4 | Delivery terms | 10 % | DDP Gatineau: 100 · DAP / CPT Gatineau: 80 · EXW / FCA (freight allowance added): 60 |
| C5 | Payment terms | 10 % | Net 60 or longer: 100 · Net 45: 85 · Net 30: 70 · shorter than Net 30 or deposit required: 40 |
| C6 | Warranty | 5 % | ≥ 24 months: 100 · 18–23 months: 85 · 12–17 months: 70 · < 12 months: 40 |

Weighted score = Σ (criterion score × weight). Criterion scores and weighted scores are carried to two decimal places; do not
round intermediate values. Lead time for EXW/FCA quotations is the supplier's stated lead time to shipment plus the stated
transit time. The supplier with the highest weighted score among compliant quotations is recommended for award, subject to
the conditions noted by the evaluator (re-confirmations, clarifications, credit check).

## 4. Deliverables of the evaluation
1. Evaluation workbook (sheet *Normalisation*: landed cost per supplier with live formulas; sheet *Scoring*: criterion scores,
   weighted scores and ranking with live formulas).
2. Recommendation memo to the Vice-President, Operations.
3. Award recommendation entered in the procurement portal (when available).

**From:** {ORG['manager']}, {ORG['manager_title']}, {ORG['name']} (Gatineau)
**To:** {ORG['analyst_role']}
**Date:** {BRIEF_DATE.isoformat()}
**Copy:** {ORG['quality']}, {ORG['quality_title']}

Good morning,

The quotation period for RFQ {RFQ_NO} closed on {RFQ_DUE.isoformat()} and we received five quotations for the annual supply
of our four Série 4000 extrusion profiles (SKUs BFI-EX-4120, -4125, -4310 and -4480). I need the full bid evaluation and an
award recommendation for {ORG['vp']} ({ORG['vp_title']}) before the operations review on Thursday. Please carry out the
evaluation yourself, end to end, following our published evaluation criteria.

## What you have (`inputs/`)
- `rfq_bfi_2025_117.docx` — the RFQ as issued: items and annual quantities, mandatory technical and commercial requirements,
  the fixed USD/CAD rate for evaluation, the freight allowance for EXW/FCA quotations (Annex B), validity requirement.
- `evaluation_criteria.md` — the approved evaluation method: compliance screening, normalisation to total landed cost in CAD,
  weighted scoring scales. Apply it exactly as written; do not invent additional criteria or weights.
- `quotes/` — the five quotations received, as PDF, one per supplier: Extrusions Laurentides Inc., Profilés Nordaluminium Ltée,
  Kingsway Aluminum Extrusions Ltd., Great Lakes Extrusion Co., Extrudal Saguenay Inc.
- `supplier_master.csv` — vendor master extract for the five bidders; `bid_receipt_log.csv` — date and time each quotation was received.

Read every quotation in full: we score what the supplier actually wrote, and suppliers do not always present their figures the
way our RFQ asks. Check that the amounts on each quotation tie before you use them.

## What I need in `out/`
1. **`bid_evaluation.xlsx`** — the evaluation workbook, with live formulas (not pasted values) so that {ORG['vp']} can
   audit it:
   - sheet **`Normalisation`**: for each supplier and each SKU, the unit price as quoted, the RFQ annual quantity, the extended
     amount as quoted and as recomputed, then per supplier: currency, FX applied, freight allowance applied, and the
     **total landed cost in CAD** per the criteria;
   - sheet **`Scoring`**: compliance status (with the reason if not compliant), the six criterion scores, the weighted score and the
     rank of each supplier, computed by formulas from the Normalisation sheet and the published scales.
2. **`recommendation_memo.docx`** — a memo to {ORG['vp']} (at least 400 words) with these sections: summary; compliance
   screening; normalised (corrected) totals, including any discrepancy you found in a quotation and its amount; scoring table;
   recommendation; conditions attached to the recommendation; next steps. Name the recommended supplier explicitly
   ("Recommended supplier: …") and state its total landed cost in CAD and the number of compliant quotations.
3. **`COMPLETION.json`** — per `COMPLETION_SCHEMA.json`; list in `issues_found` every anomaly you found in the quotations and in
   `questions` anything that must be confirmed with a supplier or with me before award.

If the procurement portal is available in your environment, also submit the **Award recommendation** form (recommended supplier,
total landed cost in CAD, number of compliant quotations, conditions). The portal document library holds the same files as
`inputs/`.

## Conventions
- Amounts in CAD, two decimals, pre-tax; show USD figures alongside their CAD conversion at the RFQ rate.
- Dates ISO 8601. The evaluation date is the date of this memo.
- Refer to suppliers by their legal name as it appears on their quotation.
- Keep the memo factual: every statement about a supplier must be traceable to its quotation or to the RFQ.

Thank you,
{ORG['manager']}
