This puts #410's code on main. #410 merged into bundle-stream-consumer-rows on 5 November at 16:07 UTC, 86 minutes after #414 had merged that branch into main, so chronicle#408's packages never reached main. #410 has the full description of what they add.

What the branch holds

• UK land value inputs for chronicle#408: MHCLG land values, VOA's 2026 stock, EPC D3, council tax by authority, the Market Value Survey, land by sector and HMRC stamp tables #410's merge, unchanged. The branch starts from 41c5b37, the commit that merged UK land value inputs for chronicle#408: MHCLG land values, VOA's 2026 stock, EPC D3, council tax by authority, the Market Value Survey, land by sector and HMRC stamp tables #410 into bundle-stream-consumer-rows. Its parents are UK land value inputs for chronicle#408: MHCLG land values, VOA's 2026 stock, EPC D3, council tax by authority, the Market Value Survey, land by sector and HMRC stamp tables #410's head (d2737e6) and Write and count bundle rows per package instead of holding them all #414's head (b71d03d), which main already has.
• One merge commit from main. 9db960f brings in Register UK area inputs for Microcosm's geography-first spine: IMD by small area with crosswalks, 2024-25 Band D, 2011 OAC #413 (chronicle#412's area inputs).
  • The only conflict was .gitignore, where both PRs added raw-only entries at the end. Both blocks are kept.
  • docs/pe-uk-source-checklist.md merged without conflict.
• The diff against main is UK land value inputs for chronicle#408: MHCLG land values, VOA's 2026 stock, EPC D3, council tax by authority, the Market Value Survey, land by sector and HMRC stamp tables #410's. It touches the same 63 files and changes the same lines.
  • Register UK area inputs for Microcosm's geography-first spine: IMD by small area with crosswalks, 2024-25 Band D, 2011 OAC #413 adds raw-only manifests, docs and its own test, but no package. It left the bundle test's counts unchanged on main, so UK land value inputs for chronicle#408: MHCLG land values, VOA's 2026 stock, EPC D3, council tax by authority, the Market Value Survey, land by sector and HMRC stamp tables #410's re-pinned counts should still hold; CI checks them.

Tests

Run locally on 9db960f:

• ruff check chronicle policyengine_chronicle db scripts tests is clean.
• scripts/build_dimension_value_register.py --static-check finds no problems.
• 292 tests pass and 3 skip, in 12½ minutes with a peak of 2.5 GiB. They cover:
  • Register UK area inputs for Microcosm's geography-first spine: IMD by small area with crosswalks, 2024-25 Band D, 2011 OAC #413's test;
  • UK land value inputs for chronicle#408: MHCLG land values, VOA's 2026 stock, EPC D3, council tax by authority, the Market Value Survey, land by sector and HMRC stamp tables #410's tests, including the label register's;
  • chronicle#407's test;
  • the UK tests that read .gitignore or walk every manifest.
• The 3 skipped tests are for earlier sources (High-value housing facts for the UK local calibration: HM Land Registry Price Paid Data, UK HPI, ONS house price statistics by constituency, the National Statistics Postcode Lookup, and the OBR High Value Council Tax Surcharge costing #343, UK local energy, area classification and Welsh bus facts: DESNZ Northern Ireland and sub-local consumption, rural-urban lookups, BUS04 country rows (PolicyEngine/microcosm#1207) #356 and the gambling survey). They need large or R2-only raw files this checkout doesn't have.

Not run locally: the bundle job's two test steps, tests/test_chronicle_uk_national_2025.py and tests/test_chronicle_bundle.py. That job took 3h16m on #410's CI, and it runs again on this PR.

Refs #408. Item 6 waits on #409.

Review of 9db960f. I checked that this is #410 as I last reviewed it (round 3 at d2737e6), now on main, with nothing added, dropped or reverted. I compared blob hashes and did not run anything locally.

How I checked

• UK land value inputs for chronicle#408: MHCLG land values, VOA's 2026 stock, EPC D3, council tax by authority, the Market Value Survey, land by sector and HMRC stamp tables #410's effect is b71d03d..41c5b37: Write and count bundle rows per package instead of holding them all #414's head to UK land value inputs for chronicle#408: MHCLG land values, VOA's 2026 stock, EPC D3, council tax by authority, the Market Value Survey, land by sector and HMRC stamp tables #410's merge commit. UK land value inputs for chronicle#408, on main (re-lands #410) #415's effect is 3a06cf1..9db960f: main to this head. Both diffs touch the same 63 files.
• 61 of the 63 files have the same before and after blobs in both diffs. That includes every package, manifest, script, test and data file, plus chronicle/bundle.py, chronicle/source_package.py and canonical_labels.json.
• The two files that differ are the two Register UK area inputs for Microcosm's geography-first spine: IMD by small area with crosswalks, 2024-25 Band D, 2011 OAC #413 also touched: .gitignore and docs/pe-uk-source-checklist.md. In both, the lines UK land value inputs for chronicle#408, on main (re-lands #410) #415 adds and removes are exactly the lines UK land value inputs for chronicle#408: MHCLG land values, VOA's 2026 stock, EPC D3, council tax by authority, the Market Value Survey, land by sector and HMRC stamp tables #410 added and removed. The .gitignore merge keeps Register UK area inputs for Microcosm's geography-first spine: IMD by small area with crosswalks, 2024-25 Band D, 2011 OAC #413's OA lookup entry and then adds UK land value inputs for chronicle#408: MHCLG land values, VOA's 2026 stock, EPC D3, council tax by authority, the Market Value Survey, land by sector and HMRC stamp tables #410's VOA zip and TPA entries.
• Main is Write and count bundle rows per package instead of holding them all #414's head plus Register UK area inputs for Microcosm's geography-first spine: IMD by small area with crosswalks, 2024-25 Band D, 2011 OAC #413 and nothing else. Register UK area inputs for Microcosm's geography-first spine: IMD by small area with crosswalks, 2024-25 Band D, 2011 OAC #413 adds no package, and none of its paths overlap with UK land value inputs for chronicle#408: MHCLG land values, VOA's 2026 stock, EPC D3, council tax by authority, the Market Value Survey, land by sector and HMRC stamp tables #410's. tests/test_chronicle_bundle.py and chronicle/bundle.py on main are byte-identical to Write and count bundle rows per package instead of holding them all #414's head, so UK land value inputs for chronicle#408: MHCLG land values, VOA's 2026 stock, EPC D3, council tax by authority, the Market Value Survey, land by sector and HMRC stamp tables #410's re-pinned counts still apply: 1,735,989 + 326,495 = 2,062,484 facts, 102,618 + 275 geographies, 554 + 46 periods and 458 + 12 packages. The per-package fact breakdown in the comment adds up to 326,495.
• Nothing from Write and count bundle rows per package instead of holding them all #414 is duplicated or reverted. This diff leaves bundle.py exactly as UK land value inputs for chronicle#408: MHCLG land values, VOA's 2026 stock, EPC D3, council tax by authority, the Market Value Survey, land by sector and HMRC stamp tables #410 left it, on top of Write and count bundle rows per package instead of holding them all #414's final head.

Earlier items: all settled on #410 and carried over unchanged. That covers the provisional years in Live Table 126, the Barnsley and Sheffield table and Microcosm alias note, and the "£2m plus" label.

CI at 9db960f: bundle, surface and checks all pass. "Test merged Chronicle bundles" ran in full and took 1h55m. The whole bundle job took 1h59m, against #410's 3h16m and the 300-minute limit, so the timing watch item can rest for now.

Verdict: this is #410's reviewed content with a clean merge of main. I have nothing further.
