-"""CFOP/IPPT auto-apply: fills or corrects ONLY C000025.CFOP and C000025.IPPT, and nothing else,
-when central.app.field_contract.resolve_product already classified the cell AUTO_FILL_SAFE
-(state=CHANGE, write_eligible=True) for this product.
-
-Safety model (defense in depth, default OFF), mirrors gti_fiscal_agent.rtc_auto_apply: the Hub sets
-a per-installation, per-capability mode DISABLED / DRY_RUN / APPROVAL_REQUIRED / ENABLED and delivers
-it inside an authenticated job (central.app.cfop_ippt_audit.job_authorizations). The Agent only
-exposes the restricted capability CFOP_IPPT_WRITE_V1; there is no local .env switch. Write allowlist:
-ALLOWED_FIELDS = ("CFOP", "IPPT") on C000025 - no free SQL, one short transaction per cell.
-
-Compare-before-write ("human override sempre vence"): every candidate carries the exact value the
-field_contract resolver saw when it was selected (`expected_before`). Immediately before the UPDATE
-the cell is re-read; if it no longer equals `expected_before` - a human (or any other process) changed
-it since - the write is ABORTED with STALE_VALUE_CHANGED_SINCE_DECISION and nothing is written; if it
-already equals the proposed value the write is skipped as NO_WRITE_REQUIRED (idempotent - a second run
-over the same candidates always writes 0). Every applied change is read back and verified; a mismatch
-never returns APPLIED. `rollback_one` restores the previous value only if the current value still
-equals what was written (a later human edit blocks the rollback too).

-# CFOP/IPPT write capability V1 — Missão 3 / Bloco C
-
-## Estado atual: núcleo implementado e testado, NÃO ligado, NÃO publicado
-
-- `agent/src/gti_fiscal_agent/cfop_ippt_auto_apply.py` — lógica pura (sem I/O de rede): `write_gate`,
-  `select_candidates` (só células `CHANGE`+`write_eligible=True` de `field_contract.resolve_product`,
-  restrito a CFOP/IPPT — nenhuma regra nova, reaproveita o motor já testado), `apply_candidate`
-  (compare-before-write, stale-write guard = "human override vence", readback, uma transação por
-  célula), `apply_candidates` (lote, uma falha nunca para o resto), `rollback_one`/`rollback_records`.
-- `agent/tests/test_cfop_ippt_auto_apply.py` — 14 testes, todos verdes: flag OFF nunca escreve; só
-  células AUTO_FILL_SAFE viram candidatas; valor alterado por humano entre a decisão e a escrita
-  aborta sem gravar (`STALE_VALUE_CHANGED_SINCE_DECISION`); segunda execução sobre a mesma célula já
-  aplicada grava 0 (`NO_WRITE_REQUIRED`); readback divergente nunca retorna `APPLIED`; rollback só
-  restaura se o valor atual ainda for o que foi escrito.
-- **Nada disto está ligado ao `execute_job` do Agent, nem existe ainda o lado Hub** (coluna
-  `Installation.cfop_ippt_write_mode`, tabela de auditoria, entrega da autorização dentro do job -
-  o mesmo padrão já usado pelo RTC, `central/app/rtc_audit.py`/`installations.rtc_write_mode`).
-  **Nenhum comportamento do Agent publicado (1.3.8) muda com este commit** — nenhum código existente
-  importa este módulo novo.
-
-## Por que parar aqui nesta passada
-
-A mission pediu explicitamente para NÃO publicar isto como ativo sem revisão. Ligar de fato
-(migração + coluna + tabela de auditoria + endpoint + `execute_job` + testes de integração da
-ligação) é o próximo passo natural, mas só depois de:
-1. Você revisar este relatório e o Bloco C.1 (candidatas rebaixadas).
-2. Decidir se a exclusão manual das 9 células de evidência fraca (ver Bloco C.1) deve ser um
-   mecanismo do capability em si (ex.: lista de exclusão por produto) ou uma melhoria futura na
-   evidência do `field_contract` (contagem/proporção de `C000032.TIPO=COMPOSICAO`, hoje é só um
-   `in`/`not in` binário no Agent, nunca uma taxa).
-
-## Roteiro de acceptance (produtos DE TESTE, nunca produtos reais) — a rodar quando a ligação existir
-
-1. **Preparar**: operador cria 2 produtos de teste no SGV de teste/sandbox (nunca em produção):
-   um com CFOP em branco e papel de produto comprovável (ex.: `TIPO=VENDA`, evidência de revenda
-   clara), outro com IPPT="T" mas uma entrada `C000032.TIPO=COMPOSICAO` clara e majoritária para o
-   mesmo CODPRODUTO.
-2. **Rodar REPROCESS_PRODUCTS em modo DRY_RUN** (capability ligada, `cfop_ippt_write_mode=DRY_RUN`):
-   confirmar que o job relata os 2 candidatos, sem nenhuma escrita (`writes_attempted=0` no
-   resultado do job).
-3. **Ligar `cfop_ippt_write_mode=ENABLED`** só para essa instalação de teste; rodar de novo:
-   confirmar `write_successes=2`, os 2 valores corrigidos no Firebird, auditoria com `old_value`/
-   `new_value`/`job_id` para cada célula.
-4. **Editar manualmente** um dos 2 produtos no SGV para um TERCEIRO valor (nem o antigo nem o
-   proposto) e disparar `REPROCESS_PRODUCTS` de novo sem terceira mudança de cadastro: como o valor
-   já bate com o proposto ou já foi decidido, a resposta esperada é `write_successes=0`
-   (`NO_WRITE_REQUIRED` se já correto, ou nada a propor se o motor já vir o valor humano como
-   `ALREADY_CORRECT`/válido).
-5. **Critério de PASS**: (i) flag OFF = 0 escritas em todos os passos; (ii) só CFOP/IPPT tocados,
-   nunca outro campo; (iii) segunda execução idêntica = 0 escritas; (iv) edição humana entre a
-   decisão e a escrita nunca é sobrescrita; (v) toda escrita aparece na auditoria com valor antigo,
-   novo, `job_id` e timestamp; (vi) rollback de uma célula aplicada restaura o valor antigo só se
-   ninguém mexeu de novo.
-
-Só depois de um PASS completo nesse roteiro (produtos de teste) é que as 12 células reais do Agent 2
-(Bloco C.1) devem ser consideradas para uma primeira aplicação real — e mesmo assim, só as que
-sustentam a evidência (ver rebaixamento no Bloco C.1), nunca o lote inteiro de uma vez.
-
-## Se/quando o Agent mudar de fato (fora desta passada)
-
-Bump para 1.3.11 (release/VERSION, `agent/pyproject.toml`, `agent/scripts/run_agent_service.py`'s
-default, `agent/src/gti_fiscal_agent/preflight.py`, todos juntos - mesma disciplina de
-`test_agent_version_is_internally_coherent`), build do installer
-(`scripts/build_agent_package.py`), validação em Windows Sandbox (`scratch_sandbox/gti.wsb` já
-existe de releases anteriores: instalar, `upgrade in-place` preservando `installation_id`/SQLite,
-confirmar `cfop_ippt_write_mode` chega `DISABLED` por padrão mesmo depois do upgrade). O upgrade na
-máquina real do Agent 2 continua sendo do operador (sem canal remoto).
