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.

sistemazioni-idraulico-forestali-operai/structural_rules_from_2021_text · base_salary · impact unknown · open

Structural rules (Art. 7, 49, 52) taken from 2021 previgente CCNL text. The 2025 rinnovo PDF is image-only and full text is unavailable for independent verification.

Applies when: base_salary applies.

Remediation: Verify the structural rules against the 2025 renewal text.

sistemazioni-idraulico-forestali-operai/apprentice_seniority · seniority · impact unknown · open

APPRENTICE SENIORITY: the CCNL text read for this ruleset does not state whether apprentices accrue the level seniority increments or an amount of their own, and no apprentice amount is modelled. The engine pays no increment during the apprenticeship (provisional); the run is affected when the apprentice has matured increments the level pays.

Applies when: seniority applies; the run takes the engine code path; contract type in apprentice.

Remediation: Source the CCNL clause on apprentice seniority and model it as seniority_increments.apprentice_amount (zero when apprentices accrue none), then remove this note.

sistemazioni-idraulico-forestali-operai/apprentice_inps_rates_unsourced · inps_employer · impact unknown · open

APPRENTICE INPS RATES: the apprentice rates of the sector (agricoltura) apply the 10% of L. 296/2006 art. 1 c. 773 plus the 1.61% NASpI, but no source found settles the disoccupazione and CISOA contributions of agricultural apprentices (INPS circ. 43/2026 gives no apprentice rates). The contributions of an apprentice may differ.

Applies when: inps_employer applies; contract type in apprentice.

Remediation: Source the apprentice rates of agricoltura (an INPS circular or an association table of 2026), mark the apprentice block of contribution/2026/agricoltura.json derived, then remove this note.

apprentice_seniority_simplified · seniority · impact unknown · resolved

Apprentices accrue only the CCNL apprentice-specific seniority increment, paid in full: the apprenticeship percentage no longer reduces it a second time. A CCNL that declares no apprentice amount pays none and carries its own open limitation /apprentice_seniority, recorded when the level pays matured increments.

Applies when: seniority applies; the run takes the engine code path; contract type in apprentice.

Remediation: Resolved: the remaining CCNLs are tracked by their own apprentice_seniority limitation.

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.

inps_minimum_base_exempt_category · inps_employer · impact unknown · open

D.L. 463/1983 art. 7 c. 5 keeps the operai agricoli out of the 9.50% minimum daily base, and the run applies no minimum to them. Tabella A of INPS circ. 6/2026 still lists 51.70 for the operai agricoli, 'non soggetto all'adeguamento' of art. 7 c. 1; no source found says whether it is a floor of their contribution base. A base below it may understate the contributions.

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

Remediation: Source the role of the 51.70 of the operai agricoli (INPS circ. 43/2026 on the agricultural contributions, or the minimum daily wages of art. 1 L. 389/1989), then apply it as their minimum or record that none applies.

Without monetary impact¶

Serie retributiva starts 01/01/2026 (first tranche with primary-source data). Retroactive 2025 tabella not available in machine-readable form; pre-2026 amounts omitted.

Apprendistato: livelli O1 e O2 esclusi da destination_levels (engine requires at least 2 levels below minimum; O2 at order=2 cannot go 2 below). Only O3, O4, O5 supported.
