Known simplifications

Each simplification below is a model limitation of the registry. An open limitation with a monetary impact (yes or unknown) makes every result it applies to not payable, with an open_limitation blocker; the result lists every applicable limitation in assurance.limitations.

enti-ricerca-aran/research_allowances_missing · base_salary · impact yes · open

ALLOWANCES: the indennità di Ente of levels IV-VIII (Tabella C5) and the indennità di valorizzazione professionale of levels I-III (Tabella C6) are stated by the CCNL only as increments from 1.1.2027, their earlier amounts set by older contracts not read: not modelled, the caller pays them.

Applies when: base_salary applies.

Remediation: Read the indennità di Ente and di valorizzazione professionale of the earlier CCNL and add them with the 2027 increments.

enti-ricerca-aran/shared_rules_unchecked · sickness · impact unknown · open

SHARED RULES: the hourly divisor, the tredicesima, the leave, absence, sickness and accrual rules are those of the scuola file of the same comparto (istruzione-ricerca-aran), not read again for the research bodies. No overtime table is modelled.

Applies when: sickness applies.

Remediation: Read the research sections of the CCNL 2019-2021 (18/1/2024) for leave, absence, sickness and overtime.

enti-ricerca-aran/perseo_sirio_not_modelled · pension_fund_contribution · impact yes · open

PENSION FUND: the staff of the research bodies join the Fondo Perseo Sirio, not modelled here.

Applies when: a fact the request cannot express: never recorded on a run.

Remediation: Model the employer and employee rates of Fondo Perseo Sirio.

sickness_inps_daily_base · sickness · impact unknown · open

The INPS share of a sick day is the INPS rate times the CCNL daily quota of the current month, counted on the CCNL payable days. INPS computes it on its own daily base (retribuzione media globale giornaliera of the month before) and on calendar days. The worker's total for the day is the same; the split between INPS indemnity (outside the contribution base) and employer integration may differ, and with it the contributions.

Applies when: sickness applies; the run takes the engine code path.

Remediation: Compute the INPS indemnity on the INPS daily base and calendar days of the INPS rules, with the pay of the month before, then resolve this limitation.

sickness_cumulation_window · sickness · impact unknown · open

The CCNL tier and the comporto are counted on the days of one episode and the relapses it continues. A CCNL that sums the sickness of separate episodes over a window (a calendar year, the last three years) can reach a lower tier or the end of the comporto earlier than the engine shows. The run is affected when an earlier episode outside the relapse chain is recorded.

Applies when: sickness applies; the run takes the engine code path.

Remediation: Add the cumulation window of each CCNL to its sickness rule, with the source, and count the tier and the comporto over it.

provisional_ruleset · irpef · impact unknown · open

The run reads a tax ruleset marked provisional: the sources of its year are not published yet (budget law of the year; regional and municipal surtax resolutions), so the values are those of the year before, carried over. Rules in force by statute (the IRPEF brackets of art. 11 and the deductions of art. 13 of the testo unico of D.Lgs. 117/2026) carry over unchanged; any change of the budget law is not applied.

Applies when: irpef applies; the run takes the engine code path.

Remediation: Replace each provisional ruleset of the year with the values of its published sources, drop its provisional flag, then resolve this limitation.

provisional_inps_ruleset · inps_employer · impact unknown · open

The run reads an INPS ruleset marked provisional: the INPS circulars of its year are not published yet, so the rates, the massimale and the minimale (and the hourly contributions of domestic work) are those of the year before, carried over. The indexed amounts change every January: the carried-over values understate them.

Applies when: inps_employer applies; the run takes the engine code path.

Remediation: Replace each provisional INPS ruleset of the year with the values of the INPS circulars of the year, drop its provisional flag, then resolve this limitation.
