Review history¶
| Date | Reviewer | Scope | Outcome | Findings |
|---|---|---|---|---|
| 2026-10-10 | claude-opus-5-5 (ai) | Whole file. The values checked were not recorded; no value was marked verified. | confirmed | The review recorded no list of the documents it read. |
| 2026-10-11 | claude-opus-5-5 (ai) | Every payable rule of the file (98 records) read again in the signed texts: the renewal of 7 March 2024 and the CCNL testo definitivo of 21 January 2021 deposited at CNEL (B101), which the 2024 renewal leaves unchanged for these articles. | corrected | 96 records match their source and are verified; the two corrected rules below are verified too. The 34 records that cited the mysolution.it summary sheet now cite the CNEL testo definitivo. Pages are physical PDF pages (the printed page of the CNEL text is two lower). Corrected: the leave tiers of Art. 42 start after the 10th and the 15th year (120 and 180 months), not 132 and 192. Corrected: Art. 51 b) deducts unworked hours by the ratio 173 / working hours of the month, and Art. 50 keeps 1/25 for Sunday holidays, so the absence rule is by_month_hours instead of by_25. Not modelled, each underpaying: night overtime after the first hour (76%), the 25% and 35% bands for daytime overtime beyond 48 hours, and the sickness tiers of 10 and 12 months for longer service. The IND_FUNZIONE clause is Art. 46 g), not Art. 47. No renewal signed after 7 March 2024; the contract expired on 30 June 2026 and a renewal is under negotiation. |
| 2026-10-12 | claude-opus-5-5 (ai) | Overtime bands of art. 35 and the sickness rule of art. 60, follow-ups of the review of 2026-10-11. | corrected | Overtime: the 25% (49th weekly hour), 35% (beyond) and 76% (night after the first hour) bands were missing; added, the night threshold read per day. Sickness: only the band up to 3 years was modelled, per episode and on the gross pay; now three seniority bands within 36 months, on the net pay, with the restart after 4 months without sickness (derived: months of 30 days, band edges read on completed months). |
| 2026-10-12 | claude-opus-5-5 (ai) | Special cases of the comporto (art. 60 B as rewritten on 7 March 2024). | corrected | The longer comporto of the malattie invalidanti (+2, +3, +4 months) and the hospital stays over 5 days left out of the comporto (60 days at most) are now modelled; the restart from the 16th day of a hospital stay and the periodic checks stay a limitation. |
| 2026-10-12 | claude-opus-5-5 (ai) | Restart of the sickness treatment from the 16th day of a hospital stay (art. 60 C). | corrected | From the 16th day of a hospital stay the treatment starts anew (full pay again): modelled with hospital_restart_day 16. |
| 2026-10-12 | claude-opus-5-5 (ai) | Restart 12 months after the end of the full pay and periodic checks (art. 60). | corrected | The last special cases of art. 60 are modelled: the restart 12 months after the full pay ended and the periodic checks out of the comporto; the limitation sickness_special_cases is closed. |

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.
concia-unic/higher_overtime_bands · overtime · impact yes · open
OVERTIME: every band of art. 35 is modelled: 15% to the 48th weekly hour, 25% the 49th, 35% beyond; night 61% the first hour, 76% after (first hour read per day); holiday 71%. The percentages do not add up ('la maggiore assorbe la minore', p. 57). The engine pays the first tier of an overtime event and flags the bands past a threshold (overtime_tier_not_applied): the caller passes the multiplier for the hours past a threshold.
Applies when: overtime applies.
Remediation: Pass the multiplier on the overtime event for the hours past a threshold; the engine does not split an event by weekly or daily hours.
concia-unic/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.
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
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.
tfr_compensation_apprentice_guarantee_fund · inps_employer · impact yes · open
An apprentice whose TFR goes to a pension fund or to the Fondo Tesoreria takes the 0.28-point relief of D.L. 203/2005 art. 8, but not the exemption from the 0.20% Fondo di garanzia contribution of D.Lgs. 252/2005 art. 10 c. 2: no source found says whether the apprentice rate (10% of L. 296/2006 art. 1 c. 773 plus NASpI and the integration funds) holds a Fondo di garanzia share to exempt. The employer contributions of the run may be overstated by 0.20% of the INPS base.
Applies when: inps_employer applies; the run takes the engine code path; contract type in apprentice.
Remediation: Find an INPS source on the Fondo di garanzia share of the apprentice rate, then exempt it with the other workers or record that none is due.
Without monetary impact¶
DAILY DIVISOR: Art. 51 b) of the CCNL testo definitivo 21/01/2021 (CNEL B101, physical pp. 69-70) deducts the normal hours not worked by the ratio 173 / working hours of the month; Art. 50 keeps the quota of 1/25 for the holidays falling on a Sunday. Modelled as by_month_hours: one share per Monday to Friday out of the Mondays to Fridays of the month.
LEAVE: Art. 42 of the CCNL testo definitivo 21/01/2021 (CNEL B101, physical p. 62): 4 weeks (20 days) up to the 10th year of service completed; 4 weeks + 2 days beyond the 10th year (120 months); 4 weeks + 3 days beyond the 15th (180 months); 5 weeks (25 days) beyond the 18th (216 months). ROL 68 ore/anno not modelled.

Coverage notes
SALARY MODEL: split. base_salary = minimo tabellare (Allegato n. 1, CCNL 07/03/2024). EDR = 10.33 EUR (Accordo 31/07/1992, all levels). IPO = Indennità di posizione organizzativa, level-specific time series per tranche (levels B1, C1, D1, E1, E2). IND_FUNZIONE = 25.82 EUR (level A only, Indennità di funzione, art. 47 CCNL 2017). Back-calculation: D1 total 01/01/2026 = 2041.99+123.67+10.33 = 2175.99; kitech confirms 2176.00 (rounding). B1 total = 2494.04+222.01+10.33 = 2726.38; kitech confirms 2726.38. A total = 2937.60+25.82+10.33 = 2973.75; kitech confirms 2973.75.
DECORRENZA: economic decorrenza 01/07/2023; first tranche 01/03/2024. Arretrati for 2023-07-01 to 2024-03-01 paid as lump sum. Series starts at 2024-03-01. SIMPLIFICATION: pre-tranche salary not modeled.
HOURLY DIVISOR: contract states 'quota oraria = retribuzione mensile / 173' (Allegato n. 1). Cross-check: 40h/week × 52 / 12 = 173.3; divisor 173 verified. Source: primary CCNL PDF filctemcgil.it.
IPO CROSS-CHECK: MySolution 2017 IPO at 01/05/2019: B1=182.63, C1=91.62, D1=103.98, E1=128.23, E2=73.02. Allegato n.1 pre-renewal (30/06/2023): B1=192.63, C1=96.62, D1=108.98, E1=135.73, E2=75.52. Deltas B1+10.00, C1+5.00, D1+5.00, E1+7.50, E2+2.50 — all clean round figures consistent with 2019-2023 renewal cycle.
APPRENTICESHIP: under_classification per MySolution sintesi 2017 p. 5 (Allegato apprendistato). 6 tracks by destination level, all with levels_below 2 → 1 → 0. D1 period-2: source table prints E2, but 10 of 11 destination tracks are monotone 2->1->0; E2 (order 3) below D1 (order 6) would cut pay mid-track, so D2 (order 5, exactly 1 below D1) is the only consistent reading. Max 36 months per D.Lgs. 167/2011 as amended 26/04/2012 (footnote in source).
SICKNESS: seniority bands of art. 60 modelled as a cumulation (8, 10, 12 months of comporto within 36 months; 3, 4, 5 months in full and the rest at half, on the net pay); restarts after 4 months without sickness, from the 16th day of a hospital stay (within the episode) and 12 months after the end of the full pay; comporto 2, 3, 4 months longer for an invalidating disease; hospital stays over 5 days (60 at most) and periodic checks of an oncological illness left out of the comporto.
SENIORITY: biennial (cadence_months=24), maximum 5 increments, amounts per level from Art. 48 of the CCNL testo definitivo 21/01/2021 (CNEL B101, physical p. 67), which the 2024 renewal leaves unchanged.
