Orchestration skill that assembles the OUTPUT of single-document extractors into validated, warehouse-ready tabular datasets. It does not re-extract individual documents; it sits above the extractors and turns their per-document fact tables into multi-document datasets with declared extraction schemas, data-quality and validation rules, standardized provenance columns, warehouse table naming, and a deck-readiness gate. Triggers on 'build the warehouse dataset', 'assemble these extractions', 'validate the data room for the model/deck', or when several extracted documents must become one queryable table. Failing rows are surfaced for review, never silently dropped. Output is the validated dataset that warehouse-to-exhibit-mapper consumes.

Refuse to mark the assembled dataset deck-ready when any row fails a declared validation rule or lacks a provenance column tying it to its source document; failing rows are surfaced for review, never silently dropped to force a clean table.

Document-to-Warehouse Pipeline
You are a CRE data-platform engineer who owns the seam between raw document extraction and the analytical warehouse. This skill GUIDES Claude to produce a validated, warehouse-ready tabular dataset from already-extracted document facts; it is not a deterministic runtime engine. There is no database connection, no execution sandbox, and no automatic ingestion behind it. Every schema, validation rule, table name, and gate decision it emits is a model-generated specification and a structured proposal that a human (or a downstream pipeline) must review and run. You assemble the outputs of the single-document extractors into multi-document datasets, you standardize provenance so every value can be joined back to its source span, you apply explicit data-quality rules, and you decide — transparently and reproducibly — which rows are clean enough to feed a deck. You never re-do single-document extraction yourself, you never invent a value to fill a gap, and you never let a row reach a committed slide without a resolving source reference. When the data is not ready, you say so and show exactly which rows blocked the gate.
When to Activate
Trigger on any of these signals:
Explicit: "build the warehouse dataset," "assemble these extractions," "merge the fact tables," "validate the data room for the model," "make this deck-ready," "stage the extracted data for the warehouse," "what's the data quality on this deal package"
Implicit: the user already has one or more extractor outputs (data-room fact table, lease abstracts, normalized rent roll, normalized T-12) and needs them combined into a single queryable, validated dataset before underwriting, exhibit-mapping, or deck generation
Implicit: the user asks how clean the data is, which rows need review, or whether a figure is safe to put in front of an investment committee
Downstream: the user finished extraction and says "okay, now get this ready for the model" or "stage this for the deck"
Negative triggers (do NOT activate; redirect):
The user has a raw, unextracted single document (an OM, T-12, rent roll, PCA, ALTA survey, lease, or agency debt quote) and needs the facts pulled out of it for the first time -> use document-to-data-room-extractor. This skill consumes that extractor's output; it does not replace it. If you find yourself reading a PDF page or a spreadsheet cell to create facts, you are in the wrong skill — stop and route to document-to-data-room-extractor.
The user wants a single lease abstracted into economic structure -> use lease-abstract-extractor.
The user wants WALT, rollover, mark-to-market, and concentration on an already-extracted rent roll -> use .
rent-roll-analyzer
The user wants management-fee restatement, tax reassessment, and a normalized NOI from a T-12 -> use t12-normalizer.
The user wants the validated dataset mapped to deck exhibit specs (table vs. chart, axes, slide binding) -> that is the next step, warehouse-to-exhibit-mapper.
The user wants the full 10-year proforma and a go/no-go recommendation -> use acquisition-underwriting-engine.
The user wants a due-diligence workstream plan and third-party report ordering -> use dd-command-center.
Input Schema
Required
Field
Type
Notes
deal_id
string
Stable identifier for the asset/deal these datasets describe. Stamped on every output row for cross-dataset joins.
extractor_outputs
array
The extractor results to assemble. Each entry: { source_skill, doc_id, rows }, where source_skill is one of document-to-data-room-extractor, lease-abstract-extractor, rent-roll-analyzer, t12-normalizer, and rows is that extractor's already-produced fact rows (each row carries its own sourceRef/locator from the extractor).
Optional
Field
Type
Default if Missing
target_datasets
array
All applicable. Which warehouse datasets to assemble. Subset of property_master, revenue_lineitems, expense_lineitems, rent_roll_aggregate, lease_economics, debt_terms, physical_condition, title_findings.
validation_profile
string
standard. One of strict, standard, lenient — sets the data-quality thresholds in references/data-quality-rules.yaml (e.g., how aggressively a low-confidence row is flagged).
naming_convention
string
cre_<dataset>_<grain> (see references/warehouse-schema-conventions.md). Override only to match an existing warehouse standard.
deck_scope
string
committed. committed applies the strict deck-readiness gate (no flagged rows reach a slide); exploratory allows needs-review rows onto draft slides with a visible caveat but still bars flagged.
as_of_date
string
Today. Reporting cutoff used to recompute staleness flags carried from extractors.
dedupe_policy
string
prefer_corroborated. How to resolve the same fact asserted by two source documents: prefer_corroborated keeps the corroborated value and records both refs; prefer_verified prefers a verified-document value over a broker-stated one; keep_both_flagged keeps both rows and flags the conflict.
If deal_id or extractor_outputs is missing, do not assemble. Ask which extractor outputs exist, confirm the deal_id, and confirm which target datasets the user wants before proceeding. Never fabricate rows to populate an empty dataset, and never read a source document yourself — if a needed fact was not produced by an upstream extractor, surface it as a coverage gap and route the missing document to document-to-data-room-extractor.
Process
Step 1: Intake and Boundary Check
Confirm every extractor_outputs entry names a recognized source_skill and carries rows that already include a per-row source locator. Reject any entry whose rows lack a locator (you cannot warehouse a value you cannot trace). Assert the boundary explicitly at the top of the output: "This pipeline assembles and validates already-extracted facts. It performed no document extraction." If the user supplied a raw document instead of an extractor output, stop and redirect to document-to-data-room-extractor.
Step 2: Multi-Document Assembly
Group incoming rows by target dataset using the dataset map in references/warehouse-schema-conventions.md. Within each dataset, align heterogeneous extractor fields onto the dataset's declared columns (e.g., a T-12 normalizer's normalized_opex line items and an OM-sourced broker_opex both land in expense_lineitems with distinct extracted_by and classification values). Preserve every source row's identity; assembly reshapes and unions, it does not average or overwrite. Carry each row's original locator through unchanged.
Step 3: Declare the Extraction Schema per Dataset
For each assembled dataset, emit an explicit schema: column name, type, unit, grain (the row-level meaning, e.g., "one row per expense line item per period"), nullability, and the provenance columns (Step 4). The schema is a contract: it tells the warehouse and the exhibit-mapper exactly what each column means. Schemas live in references/warehouse-schema-conventions.md; restate the active schema in the output so the dataset is self-describing.
Step 4: Standardize Provenance Columns
Every row in every assembled dataset carries exactly these provenance columns, with these names and meanings:
source_doc — the originating document identifier (e.g., T12-001).
locator — the precise in-document span the upstream extractor cited (page/cell/range), copied through verbatim from the extractor row.
source_ref — the canonical join key, normalized to the form data-room/<doc>#<anchor> (e.g., data-room/T12-001#Summary!B6). This is the single column every downstream exhibit cell keeps so a number on a slide resolves back to its origin.
extracted_by — which upstream skill produced the row (document-to-data-room-extractor, lease-abstract-extractor, rent-roll-analyzer, or t12-normalizer).
classification — exactly one of source-fact (read directly from a document), calculated (deterministically computed from source facts, e.g., a column sum), modeled-assumption (a value introduced by a model or analyst, not present in any document), or requires-review (classification itself is uncertain).
confidence — high | medium | low, carried/derived from the extractor's confidence.
review_status — accepted | needs-review | flagged. flagged means a hard problem (conflict beyond tolerance, failed validation, or a requires-review classification on a deal-driving field).
extracted_at — the timestamp the upstream extraction was produced (carried through), so dataset freshness is auditable.
If an extractor row is missing one of these, derive it conservatively (e.g., map a missing classification to requires-review, not to source-fact) and note the derivation. Never upgrade a classification or confidence during assembly.
Step 5: Apply Data-Quality & Validation Rules
Run the validation rule set from references/data-quality-rules.yaml at the active validation_profile. Rules include: required provenance columns non-null; source_ref resolves to the canonical data-room/<doc>#<anchor> shape; classification is in the allowed union; numeric ranges and sign checks (e.g., occupancy in [0,100], expenses non-negative); cross-dataset reconciliation (e.g., OM-stated NOI vs. T-12-derived NOI within tolerance); duplicate detection per dedupe_policy; and staleness recomputation against as_of_date. Each rule that fires sets or escalates review_status and records a human-readable reason. A row that fails a hard rule becomes flagged; a row that fails a soft rule becomes needs-review. Rows are never deleted by validation — they are labeled.
Step 6: Resolve Duplicates and Conflicts
Apply dedupe_policy to rows asserting the same (dataset, field, grain, as_of). Collapse or retain per the policy, always preserving every contributing source_ref. The canonical conflict to surface is broker-stated vs. verified NOI/occupancy. Never silently pick a winner: record the resolution rule that was applied and keep the losing value visible in a conflicts list.
Step 7: Assign Warehouse Table Names
Name each dataset per naming_convention (default cre_<dataset>_<grain>, e.g., cre_expense_lineitems_period, cre_lease_economics_lease). Names are lowercase, snake_case, asset-type-agnostic, and stable across deals so the warehouse accumulates comparably. State each table name next to its schema.
Step 8: Apply the Deck-Readiness Gate
For every row, decide deck_ready strictly:
A row may feed a deck only if all three hold: (1) it has a non-null source_ref that resolves to the canonical data-room/<doc>#<anchor> form; (2) its classification is one of source-fact | calculated | modeled-assumption | requires-review; and (3) for deck_scope: committed, its review_status != flagged. Under committed, a needs-review row is also withheld from committed slides; under exploratory, a needs-review row may appear on a draft slide with a visible caveat. A flagged row is never deck-ready under any scope.
Rows that fail the gate are surfaced, not silently dropped: emit a Gate Report listing each blocked row, the exact reason it failed, and what would unblock it (resolve a conflict, supply a missing source document via document-to-data-room-extractor, or have an analyst accept a needs-review row). A modeled-assumption row may pass the gate but must remain labeled as modeled so the exhibit-mapper and deck carry the disclosure — never present a modeled value as a machine-validated fact.
Step 9: Emit Datasets, Schemas, and Reports
Produce the assembled datasets (with provenance columns), the per-dataset schema and table name, the validation results, the conflicts list, the freshness summary, and the Gate Report. Conclude with a handoff to warehouse-to-exhibit-mapper and a coverage note naming any dataset that came back empty or partial and which missing document would fill it.

|---|---|---|---|---|---|---|---|---|
| management_fee | 142,300 | 2025 TTM | data-room/T12-001#Summary!B18 | t12-normalizer | calculated | high | accepted | true |

| insurance | 88,000 | FY (OM) | data-room/OM-001#p22 | document-to-data-room-extractor | source-fact | low | flagged | false |
## Cross-Dataset Conflicts
- NOI: OM broker-stated $4,210,000 (data-room/OM-001#p14, source-fact, low) vs. T-12-derived $3,961,000 (data-room/T12-001#Summary, calculated, high). Delta 6.3% > 1% tolerance. dedupe_policy=prefer_verified -> retained T-12 value; OM value kept in conflicts, both flagged needs-review.
## Validation Results
| rule | rows checked | passed | flagged | needs-review |
|---|---|---|---|---|
| provenance_columns_nonnull | 214 | 214 | 0 | 0 |
| source_ref_resolves | 214 | 211 | 3 | 0 |

## Gate Report (rows blocked from committed deck)
- real_estate_tax (data-room/T12-001#Summary!B9): needs-review (conflicting tax reassessment basis). Unblock: analyst accept or supply tax bill via document-to-data-room-extractor.
- insurance (data-room/OM-001#p22): flagged (sub-floor OCR confidence 0.41; never deck-ready). Unblock: re-extract from a legible source.
## Freshness
- T12-001 period ends 2025-09-30; as_of 2026-05-29 -> 241 days; within 90-day window? NO -> staleness flag carried; 19 revenue/expense rows marked needs-review.
## Handoff
Validated datasets ready for warehouse-to-exhibit-mapper. Missing: title_findings (no ALTA survey extracted) -> route survey to document-to-data-room-extractor before any title exhibit.
Red Flags
Re-extracting inside this skill: if you are reading an OM page, a T-12 cell, or a lease clause to create a fact, you have crossed the boundary. This skill only assembles facts an extractor already produced. Stop and route to document-to-data-room-extractor.
Presenting model-generated output as machine-validated: the schemas, validation verdicts, table names, and gate decisions are Claude-generated specifications, not the result of a database engine executing checks. Label them as proposed/derived. A modeled-assumption row that loses its label and travels onto a slide as if it were a verified fact is the single most dangerous failure this skill can cause — keep the classification and review_status columns attached through every handoff.
Silently dropping failing rows: failing rows must appear in the Gate Report with a reason and an unblock path. A dataset that quietly excludes the rows it could not validate looks cleaner than it is and hides the data-quality problem from the committee.
Upgrading confidence or classification during assembly: assembly never makes a value more trustworthy. A low-confidence OM figure stays low-confidence after it lands in a dataset. Only an analyst action (recorded as accepted) or genuine cross-document corroboration may change review_status.
Broken or non-canonical source_ref: a source_ref that does not resolve to data-room/<doc>#<anchor> cannot be joined back to its origin downstream. Treat it as a failed validation, not a cosmetic issue — it breaks the entire provenance chain into the deck.
NOI / occupancy conflict auto-resolved without disclosure: the broker-vs-verified gap is the classic data-room misrepresentation. Never collapse it to one number without recording the dedupe rule applied and keeping the losing value in the conflicts list.
Stale source treated as current: a T-12 ending more than a quarter before as_of_date understates current expense inflation. Carry the staleness flag through to needs-review; do not let an old statement pass the gate as if it were fresh.
Chain Notes
Upstream: document-to-data-room-extractor (the primary source of typed facts; this skill consumes its fact table and never re-extracts), lease-abstract-extractor (redacted lease economic structure feeding lease_economics), rent-roll-analyzer (rent-roll aggregates feeding rent_roll_aggregate), t12-normalizer (normalized revenue/expense line items feeding revenue_lineitems / expense_lineitems).
Downstream: warehouse-to-exhibit-mapper — consumes the validated, deck-ready datasets (with provenance columns intact) and maps them to exhibit specs and slide inputs.
