VERIFIER SHEET — PILOT ROUND	INSTRUMENT SHAKEDOWN, n=4

THIS IS A PILOT, NOT THE AGREEMENT STUDY	Read this line before anything else.
Purpose	Shake down the instrument: does the codebook produce consistent answers, are the columns the right columns, is anything ambiguous.
What it is NOT	This is not the main agreement round. No headline agreement statistic is claimed from n=4.
Codebook may change after	Refinement is EXPECTED after this round. That is the point of a pilot.
Main round	Runs later on the full cohort, against a codebook frozen after this pilot's findings are folded in.

SCOPE — why 4 rows
Population	4. This is the COMPLETE set of distinct real EDGAR filings in the repository, not a sample of a larger set.
Not an under-pull	5 XML files exist; 0001594162.xml at the repo root is byte-identical (SHA-256 f8dcf202...) to the td6_real_sources copy. 5 files, 4 distinct filings.
Why so few	The pipeline is designed for a 500-firm cohort. These 4 are the verification sources committed to the repo. A larger cohort requires a live EDGAR pull, which is a separate action.

HOW TO USE
1	Click OPEN SEC FILING in column E. It goes to the SEC's own filing index — the primary source.
2	Compare each extracted value against the filing. Do not compare against memory or another sheet.
3	Fill only the ANSWER_ columns (amber headers). Leave every other column untouched — they are the extraction under test.
4	One row at a time, top to bottom. Do not batch-judge.
5	Record your actual start and end time. Both go in the receipt.

COLUMN DEFINITIONS — one line each
row_id	Stable identifier for this row. Never reuse or renumber.
cik	SEC Central Index Key of the primary issuer, zero-padded to 10.
issuer_name	Entity name exactly as filed. Case and punctuation are part of the value.
accession_no	SEC accession number identifying this specific filing.
filing_link	Clickable link to the SEC filing index. This is the receipt for every value in the row.
form_type	D = new offering notice. D/A = amendment to a prior notice.
is_amendment	true when the filing amends an earlier one.
jurisdiction_of_inc	Where the issuer is incorporated. Not necessarily where it operates.
issuer_state_country	Mailing address state or country, as filed.
entity_type	Legal form: limited partnership, corporation, LLC, other.
industry_group	Issuer's self-selected industry classification.
investment_fund_type	Fund category when the issuer is a pooled investment fund.
is_pooled_fund	true when the issuer files as a pooled investment fund.
total_offering_amount	Total offering size in USD, or the literal 'Indefinite'. 'Indefinite' is a VALID value, not a gap.
total_amount_sold	USD sold to date at filing time.
total_remaining	Offering amount still available. Should equal offering minus sold when both are numeric.
min_investment_accepted	Smallest accepted investment in USD. 0 means no stated minimum.
has_non_accredited	true when any non-accredited investor participated.
investors_already_invested	Count of investors at filing time.
signature_date	Date the filing was signed, as filed.
signature_name	Name on the signature block.
source_file	Repository path of the parsed XML, so any value can be traced back to bytes.
ANSWER_issuer_name_correct	YES / NO / LOW. Does the extracted name match the filing exactly?
ANSWER_offering_amount_correct	YES / NO / LOW.
ANSWER_amount_sold_correct	YES / NO / LOW.
ANSWER_fund_type_correct	YES / NO / LOW.
ANSWER_confidence	HIGH or LOW for the row overall. See the LOW protocol below.
ANSWER_receipt	Where you looked. Section or item of the filing. Required for every NO and every LOW.
ANSWER_notes	Anything the columns above cannot hold. Ambiguity in the codebook belongs here — it is a pilot finding.

LOW-CONFIDENCE PROTOCOL
When to use LOW	Whenever you cannot settle the answer from the filing alone. LOW is a real answer, not a failure to answer.
Never guess	A guessed YES is worse than a LOW. YES is used downstream as verified; LOW routes the row to adjudication.
LOW needs a receipt	Every LOW must say in ANSWER_receipt what you checked and what was missing or ambiguous.
Ambiguity is a finding	If the filing or the codebook is ambiguous, that is a pilot finding. Mark LOW and say so in notes.
Do not resolve upward	Two LOWs on one row do not make a NO. Leave them LOW.

RECEIPT FORMAT
Shape	<where you looked> -> <what it said>
Example (agreement)	Item 13 Offering Amount -> $202,490,000, matches
Example (disagreement)	Item 13 -> 'Indefinite'; sheet shows a number. Filing wins.
Example (LOW)	Item 6 -> two fund types checked; sheet carries one. Cannot tell which is primary.
Rule	A receipt names a location in the filing. 'Looks right' and 'checked' are not receipts.

TIME	Deadline is tomorrow 10:00 EDT if quality requires it. Record actual start and end times; duration is disclosed, not constrained.
