Census 2023 weekly rent paid by households, by regional council (NZ, G8-d1)

[MaxGhenis]

Adds Census 2023 weekly rent paid by households for New Zealand, the 16 regional councils and the Area Outside Region: 162 published facts from the Stats NZ Place Summaries files that #335 already pinned. This is package G8-d1 of microcosm#1183. Microcosm NZ's rent input (method card MC8) needs a rent distribution, and Chronicle had none.

No new source file, no new R2 object: the family reads the 18 CSVs in db/data/stats_nz/census_2023_place_summaries/ exactly as the #335 families do.

What this adds

packages/stats_nz/census_2023_weekly_rent/: a national root plus 17 rc_XX children (rc_01–rc_09, rc_12–rc_18, rc_99), 18 aliases, nine facts per place.

Section	Categories	Value type	Facts per place
Weekly rent paid by households	Under $200; $200 - $299; $300 - $399; $400 - $499; $500 - $599; $600 - $699; $700 - $799; $800 and over	Count	8
Median weekly rent paid by households	the table row	Median (nzd_per_week, aggregation: median)	1

Spot values, checked against the files:

• New Zealand bands: 89,439; 53,325; 80,247; 101,067; 99,042; 68,544; 32,286; 35,712. Median $450.
• Auckland Region bands: 28,113; 9,909; 16,734; 28,827; 42,645; 37,143; 19,629; 22,899. Median $540.

Not emitted, but preserved in the pinned files: Percent rows, the 2013 and 2018 periods, and the Māori-ethnic-group sections. The median also appears as a Quick-stats row with the same value. The package selects the table row, by its row identity, as the #335 families do for duplicated quick stats.

What the product doesn't state, and the package doesn't assert:

• the rent population, for example whether these are rented occupied private dwellings with a stated rent;
• the regional boundary vintage;
• any rounding note.

The reference date is census night, 7 March 2023.

Invariants and how they're checked

• One CSV row per fact, with no sums. New Zealand rows are their own facts, never a sum of regions. The bands are never totalled.
• Exact selection. The test declares every expected fact from literal lists (place, section, category, row identity), independent of the package YAML, and requires exactly that set.
• Status lineage. confidentiality_indicator and final_indicator travel with each fact. A flagged row is never emitted as a number. All 162 selected rows are unflagged.
• Labels as published, including the spacing in $200 - $299. Every dimension and value carries a label (Dimension labels are only checked for the UK suite: 68 of 79 other packages fail the consumer_fact.v2 rules #265).

Mutants that fail the tests:

• a Percent row in place of a Count row;
• a 2018 row in place of 2023;
• Northland's file read for Auckland;
• a Māori-ethnic-group row in place of the total-population row;
• the Quick-stats median in place of the table median;
• a band relabelled as its neighbour.

Tests

• tests/test_chronicle_nz_census_weekly_rent.py: 185 cases. The build lane ran it, and the hub re-ran it on the final tree after merging main. It covers validate-package and a single-source suite for all 18 members.
• tests/test_chronicle_nz_census_households.py (186) and the alias-drift tests still pass. Since Discover nested source-package members so the alias-drift guard sees them #338, the drift guard sees the nested members.
• The full-bundle node is left to CI.

Bundle pins

Measured against main 3c113e8a (#338, merged since, changes no pins):

• facts +162 (1,004,092 → 1,004,254), of which 144 are counts and 18 medians;
• packages +18 (359 → 377); tables +1 (318 → 319);
• geographies +0, sources +0, warnings +0;
• by_source stats_nz +162; household +162; calendar_year:2023 +162;
• each of the 18 existing Census geographies +9.

Chronicle governance

• Agent role: ledger-source-ingestor. The per-package files outside its allowed_paths are the alias entries in chronicle/source_package.py, the checklist row, the changelog fragment and the bundle pins.
• Judges: the build lane's local independent reviewers gave ledger-source-fidelity: PASS (all 18 packages match exactly the 162 physical rows; checksums and sizes match) and ledger-boundary: PASS (direct values, distinct count and median units, no computed values). The independent review that follows is asked for both as named verdicts.
• Receipts: the 18 objects were published and verified for Add Stats NZ 2023 Census household and family counts by regional council #335. chronicle verify-raw --root db/data/stats_nz/census_2023_place_summaries --manifest 'manifest-*.yaml' re-checks them.

Merged by the NZ hub (session local_e407a527) at 239bf84 with --squash. Gates: gh pr checks exit 0; MERGEABLE; not draft; no CHANGES_REQUESTED review. Reviewed head: 239bf84. Delta review 20261012-045000 (GPT-6.1 Sol) APPROVE_WITH_NITS at 239bf84: alias drift 28 passed, bundle 24, weekly rent 185; ledger-source-fidelity PASS, ledger-boundary PASS. Its 'Needs Max' flag was for publishing Stats NZ's own census figures (162 facts, no PolicyEngine number); hub judged no, as for #209 under d962. Nit not applied: evidence.md already discloses that the hub supplies the census date (7 March 2023) and NZD basis and that the CSVs state only 2023/Census/dollars; a publisher citation for both rides the next Stats NZ package (G8-d2).
