-# FEC candidate data dictionary
+# FEC data dictionary
 
-237 column entries across ten tables and four views. NULL rates use the complete prechange audit, verified again after metadata creation. Examples inspect at most the first 10,000 rows; empty examples do not imply all values are missing. View statistics are not materialized. Snapshot and interpretation limitations are documented below.
+Snapshot: 2026-11-09.
 
-This dictionary describes the identified [candidate snapshot](README.md). Fourteen 2022 occupation/employer fields lose balanced wrapper quotes under the strict double-quote CSV interpretation; thirteen separate malformed literal-quote recoveries retain literal quotes. FEC's field page does not specify quote escaping. Eight malformed nonblank 2016/2018 date tokens remain NULL with raw values and identifiers in the [quality report](sources-2026-10-18.json). The latest committee 2024 source contains one additional row relative to this snapshot. No extra row or guessed date correction was silently applied.
+Null percentages are exact full-source-table counts rounded to one decimal place. Examples are omitted. Statistics for v_candidate_totals, v_daily_donations, and v_top_donors are unavailable; their SQL definitions are unchanged.
+
+Join entity IDs with `cycle`. Aggregate child transactions before joining to avoid fan-out. Values are source fields, not validated identities; donor strings are not a reliable unique-person key.
+
+Contributor names/addresses are subject to [FEC use restrictions](https://www.fec.gov/updates/sale-or-use-contributor-information/).

+## Snapshot and verification
+
+This is a source-identified snapshot, not a live feed. The current-main URLs above follow the latest publication. For reproducible work, replace `main` with the immutable dataset revision you downloaded. Source URLs can change without notice; provenance records individual acquisition times, hashes and sizes.
+
+The refresh adds a net **3,832,549 rows** relative to the October 18 snapshot. This is not a count of new donors or new cash. Master-table rows are entity/cycle records; transaction rows retain reported multiplicity.
+
+The current official 2022 individual-contributions ZIP has a truncated root member: 23,747,535 physical records with a partial last record. Its 34 official date shards independently reproduce all 63,885,802 typed baseline rows and all four SHA-256 limb sums. This release restores that complete baseline-equivalent cycle. It does not treat the root load as complete.
+
+Strict current-source CSV checks cover all 27 standalone source/cycle partitions. Before publication, strict checks corrected a net 1,199 rows lost by this rebuild’s permissive CSV ingestion across 16 partitions. Of the 27 current typed multisets, 23 match the prior snapshot and four differ. Independent-expenditure raw source counts are reported separately from amendment-filtered final counts. Three current operating-expense sources require normalization of exactly one empty terminal field.
+
+[Provenance](sources-2026-11-09.json), [dictionary](DICTIONARY.md), and the [portable snapshot validation bundle](fec-snapshot-validation-2026-11-09.zip) record the checks and source identities. The bundle includes a DuckDB 1.5.5 read-only full-fingerprint verifier, source lock, code, tests and MIT license. It does not bundle the database or raw FEC sources and does not provide an offline or one-command source rebuild.
+
+Fingerprint sums are decimal strings to avoid JSON/JavaScript precision loss. Full typed-row multiset fingerprints preserve multiplicity but do not prove hash injectivity. The separate whole-file SHA-256 identifies this database exactly.
 
 ## Interpretation and source quality
 
-Transaction rows are not unique donors or a complete census of donations. The [FEC individual-contributions file](https://www.fec.gov/campaign-finance-data/contributions-individuals-file-description/) includes a subset of reported itemized contributions under rules that changed over time. Entity IDs recur across cycles: join with `cycle` and aggregate child transactions before combining them.
+The [FEC individual-contributions file](https://www.fec.gov/campaign-finance-data/contributions-individuals-file-description/) covers a subset of reported itemized contributions under rules that changed over time. It is not a census of donations or unique people. Entity IDs recur across cycles: include `cycle` in joins and aggregate child transactions before combining them.
+
+`v_candidate_totals` and `v_top_donors` net specified refund types. `v_daily_donations` excludes refunds and reports positive non-refund transactions. `v_pac_to_candidate` selects direct 24K/24Z contributions. These are different measures. For net contributions, account for memo rows, conduit transfers and refunds; avoid join fan-out. Raw name/employer/address strings are not stable donor identities.
+
+Eight malformed nonblank individual-contribution dates from 2016/2018 remain NULL. No guessed date repair was applied. The retained 2022 interpretation removes 14 balanced wrapper quotes and separately preserves 13 malformed literal-quote fields. FEC does not specify quote escaping, so this is a disclosed interpretation choice. Other conversion/framing outcomes are summarized by source partition in the provenance.
+
+Blank fields become NULL; amounts remain DOUBLE, with floating-point rather than exact decimal arithmetic. Source outlier dates, inconsistent amounts and prank filings remain. Inspect anomalous records against filings. Historical comparisons and parsing choices are retained in the [immutable prior provenance](https://huggingface.co/datasets/Nason/fec-database/blob/aee3ae8b28685104765fb1b1e3ebc2588cb907a3/sources-2026-10-18.json).
 
-`v_candidate_totals` and `v_top_donors` net specified refund types. `v_daily_donations` instead excludes refunds and reports positive non-refund transactions; `v_pac_to_candidate` selects direct 24K/24Z contributions. Their outputs are different measures.
+The dictionary has exact base-table null percentages. Null statistics and examples for `v_candidate_totals`, `v_daily_donations`, and `v_top_donors` are unavailable after the 2022 correction. View SQL is unchanged.
 
-All 37 historical changes have documented parsing/upstream explanations. A strict double-quote CSV interpretation removes balanced wrapper quotes from fourteen 2022 fields (twelve RETIRED occupations, one POLICY occupation, one NOT EMPLOYED CURRENTLY employer). Thirteen separate malformed literal-quote recoveries retain literal quotes. FEC's field description does not specify quote escaping; this is a disclosed interpretation choice, not an official rule. Eight malformed nonblank dates in 2016/2018 remain NULL, with raw tokens/identifiers retained in the provenance. No guessed date repair was applied.
+## Resources and use restrictions
 
-A later source added committee **C00962951, CARMELA CONROY VICTORY FUND**, after the validated cutoff. It is outside this frozen snapshot. Source outlier dates, inconsistent amounts and prank filings remain; inspect unusual records against filings. Blank fields become NULL; DOUBLE amounts preserve the existing floating-point representation. For net contributions, account for memo rows, conduit transfers and refunds; avoid join fan-out.
+Disk size is not a RAM estimate. Remote queries can transfer much of the file. Contribution views aggregate large tables, and a final `LIMIT` does not guarantee a small scan. Keep the pre-attachment resource limits in the examples, leave process and disk headroom, and expect larger queries to fail when spill is disabled.
 
-The complete typed-row multiset audits, source hash/CRC checks, exact small-table comparisons and metadata verification are documented in [provenance](https://huggingface.co/datasets/Nason/fec-database/blob/aee3ae8b28685104765fb1b1e3ebc2588cb907a3/sources-2026-10-18.json).
