# screen_late_filers

> SIGNAL, NOT A VERDICT. FIIs and FIDCs whose monthly informe (FNET 'Informe Mensal Estruturado', first delivery of a versao 1 document) reached B3 Fundos.NET at least p_min_days_late days after the deadline Resolução CVM 175 states for it, in at least p_min_late of the p_months reference months ending at p_end. The deadline is cited, not assumed: FIDC — Anexo Normativo II, art. 27, III; FII — Anexo Normativo III, art. 36, I; both 15 days after the end of the reference month, counted here as calendar days (the text says dias, not dias úteis). A month is measured only from the first full month after the family's adaptation deadline (2024-12 FIDC, 2025-07 FII); a window ending earlier raises 22023. SILO applies no holiday calendar, so a deadline on a weekend or holiday may legitimately roll forward — p_min_days_late (default 5) absorbs that. informes counts the months measured, informes_late those past the threshold, max_days_late the worst, median_lag_days the fund's median delivery lag after month end, deadline_rule the citation. A late delivery is a timestamp compared with a rule, not a finding: the same row comes from an extension CVM granted, an upload that FNET timestamped after a delivery made by other means, or an administrator transfer that delayed one month for a whole book; a fund with several classes is measured on its earliest filing. A month with no informe in the register is NOT counted (FNET history is partial; absence is screen_silent_filers). Fund identity is the cnpjFundo link only, never fund_name. Defaults 12 months, 5 days, 2 late months. Every row carries screen and params. More than 1000 rows RAISES 22023 (never trimmed): raise p_min_late or p_min_days_late, or pin p_family.

**Row cap.** A window producing more than 1000 rows raises SQLSTATE `22023` naming this function. Nothing is trimmed to fit — PostgREST would silently cut the response at 1000 and a cut-short series is indistinguishable from one that simply ends. This function does not page — narrow the window instead.



## OpenAPI

openapi: 3.1.0
info:
  title: SILO Data API

  summary: >-
    Read-only Brazilian public financial data: CVM filings, BACEN series, B3
    quotes and the B3 BDI group.
  description: >
    Schema `api` over PostgREST. Views are `GET /<view>`; functions are

    `POST /rpc/<function>` with a JSON body.


    **This document is generated** from the live Postgres catalog by

    `scripts/gen_openapi.py` — `pg_get_function_arguments` for the RPC
    signatures,

    `information_schema.columns` for the view columns, and the granted-to-`anon`

    privilege set for which objects exist at all. It is not hand-maintained, and

    `tests/test_openapi_spec.py` fails the build when it drifts from the SQL.


    ### Two different ceilings


    Reading one for the other is the most expensive mistake on this API.


    * **The row cap refuses.** Fifty-nine set-returning functions raise SQLSTATE
      `22023` when the window they were handed would produce more than 1000 rows.
      Nothing is trimmed, and the error says why and how to fix it (the message,
      plus PostgREST's `details` and `hint`). Five of them (`panel`,
      `quote_history`, `fund_nav`, `index_history`, `trade_consolidated_history`)
      take a `p_after` cursor so you can walk the series; the other fifty-four ask you to narrow the window. `fund_nav` paging
      additionally REQUIRES `p_entity_type` — its cursor is a bare period, which
      is unique only within one family, and CNPJs that file under both `fi` and
      `fidc` in the same month would otherwise be ambiguous.
    * **The tier ceiling clamps.** Three other functions (`search_funds`,
      `option_chain`, `option_exercises`) silently lower `p_limit` to a per-tier maximum. No error is raised, so the
      only way to know the result was cut is to know the ceiling. Signing in
      raises it.

    Separately from both, PostgREST's server-wide `db-max-rows = 1000` cuts
    every

    response, on every endpoint, for every tier. On the GET views
    `Content-Range`

    is the signal (`0-999/*`); `Prefer: count=exact` turns the `*` into a total.


    ### Retention


    Most of this warehouse is append-only history. The **B3 BDI group** —

    `short_interest`, `short_interest_by_sector`, `investor_flow`,

    `lending_trades`, `lending_participants` — is not: B3 keeps roughly 21
    business

    days and publishes no archive. A missed session cannot be bought back. See

    Market Coverage.
