You are the Niyam encoder. Update this rulebook so it matches a new government document.

The validated change set is in .niyam/changeset.json. It lists each change with its exact source quote, page and clause. The source document is registered in sources/index.yaml as gr-202407031335114330 (date 2024-07-03).

Do this:

Read CLAUDE.md (the rulebook rules), the change set, and the files of the affected scheme(s): mh.ladki_bahin.
Apply every change in the change set, following CLAUDE.md exactly:
- parameter change: add a new dated value under values: starting 2024-07-03. Never edit or delete older values.
- condition change: set valid_until on the old condition to the day before 2024-07-03, and add a new condition with the same id and valid_from: 2024-07-03.
- condition removed: only set valid_until to the day before 2024-07-03.
- every new value or condition gets source / metadata.reference with doc gr-202407031335114330, page, clause, quote (copied from the change set) and quote_en.
- if a change needs a new person field, add it to schema/person.yaml with a safe default that keeps existing results unchanged.
Add test citizens to tests/ for every change, dated on or after 2024-07-03: just below, at, and just above each limit, plus one case dated before 2024-07-03 proving the old rule still applies. Each case cites GR 202407031335114330 p.<page> clause <clause> in source.
Add an entry at the top of CHANGELOG.md (English, Hindi, Marathi) linking to the document.
Run python -m niyam_rulebook test and fix problems until it prints 0 failed with no PROBLEM lines.
Do not run git. Do not edit files outside schemes/, parameters/, tests/, sources/, glossary/, schema/ and CHANGELOG.md.

Finish with a short summary of what you changed and the final test result.

I applied all six changes from GR 202407031335114330 to mh.ladki_bahin. python -m niyam_rulebook test prints tests: 47 passed, 0 failed with no PROBLEM lines.

Maximum age (c1): age_max now has a 2024-07-03 value of 65.
Unmarried women (c2): eligible_marital_statuses now includes unmarried from 2024-07-03.
One unmarried woman per family (c3): I added a new condition, unmarried_one_per_family, valid from 2024-07-03. schema/person.yaml already had other_unmarried_beneficiary_in_family, so I added no field.
Contract staff (c4): disqualifying_govt_jobs is now [regular, pensioner] from 2024-07-03.
Other-scheme limit (c5): I set valid_until: 2024-07-02 on the old other_scheme_limit condition. A new one from 2024-07-03 uses <, so receiving exactly Rs 1,500 now disqualifies.
Farm land (c6): I set valid_until: 2024-07-02 on farm_land_limit and added no replacement.

Every new value and condition cites the GR with page, clause, the original-language quote and the English quote.

I added 22 test cases to tests/mh/ladki_bahin.yaml. They cover each limit (age 64/65/66, other-scheme Rs 1,499/1,500/1,501, farm land 4.5/5/5.5 acres) and the contract-staff cases at and just above Rs 2.5 lakh income. There is also one case dated 2024-07-02 per change showing the old rule still applies.

I added a CHANGELOG entry in English, Hindi and Marathi linking to the GR.

Contract staff and the Rs 2.5 lakh cap: I read the cap as the existing family income ceiling, so contract staff no longer disqualify at all. The change set flags this as ambiguous, and I did not model the other reading.
Skipped topics: The change set skipped the ration-card income-certificate exemption and the document, committee and incentive changes, and I left them out.
Source index: sources/index.yaml already listed the GR and the PDF was already in sources/mh/, so I left both alone.
