- Branch:
be-2025-vintagesfromorigin/mainat5c15bfd. - Worktree inputs are staged under
.lane-raw/and must remain uncommitted. - Lane C5 is complete, validated, independently reviewed, and ready for handoff.
- The requested staged C2 report is absent, but root
LANE_C2_REPORT.mdis byte-identical to the sibling lane's staged copy (SHA-2564590e0dc...50f06e7) and is the pattern used.
- Read the repository Chronicle boundary rules in
AGENTS.md. - Read
.lane-raw/SOURCES.mdand confirmed all five named publisher artifacts are present. - Confirmed the worktree is otherwise clean apart from
.lane-raw/and the shared.venvlink. - Verified all five staged artifact SHA-256 pins exactly.
- Mapped FPB workbook cells: 990 facts across T01/T06/T07/T11/T17/T24, with
2022–2025 observations and 2026–2031
source_projectionfacts. - Confirmed PDF boundary evidence: printed page 19 calls 2026 the first projection year; annex table units appear on printed pages 45, 48, 49, 53, 58, and 65.
- Chosen Eurostat layout: two vintage-specific source-package aliases share new manifest entries, preserving the prior package YAMLs, raw bytes, and fact outputs unchanged.
- Reproduced the Statbel curator logic: 18 NUTS1 × sex × age-band cells totaling 11,825,551.
- Added the hash-pinned FPB workbook and publication PDF plus the
fpb-economic-outlook-2026-2031-june-2026package alias. - Built 990 line-specific publisher facts (99 per year): 396 observations for
2022–2025 and 594
source_projectionfacts for 2026–2031. - Passed FPB
validate-packageandbuild-suite: 990 facts, full cell lineage, zero acceptance errors, and pinned 2025 cells 320578 / 77771 / 5602 million euro. - Re-ran the Statbel 2026 curator logic on the 2025 ZIP and added the hash-pinned raw capture plus its deterministic 18-row curated CSV.
- Passed Statbel 2025
validate-packageandbuild-suite: 18 facts totaling 11,825,551, 66 constraints, full lineage, and zero acceptance errors. - Added the Eurostat
gov_10a_taxag2025 andspr_exp_func2024 manifest entries plus vintage-specific package aliases, without modifying either prior artifact or prior package specification. - Passed both new Eurostat package validations and suite builds: 12 tax facts and 9 ESSPROS facts, full lineage, and zero acceptance errors.
- Extended Belgium and Eurostat regressions for FPB table counts/cells and assertion boundary, vintage non-overlap, prior-output digests, Statbel pins, and the declared 0.25% Statbel/FPB population comparison tolerance.
- Passed 43 focused tests and the full merged-bundle regression: 157,177 facts, 148 packages, zero aggregate-key duplicates, and expected goldens throughout.
- Recorded pins, counts, boundary evidence, curator commands, validation tails,
and consumer fact families in
LANE_C5_REPORT.md. - Passed independent
ledger-source-fidelityandledger-boundaryreviews with no required corrections.
- None; ready for handoff. No push was performed.
