Independent reviews of the five WSL data and skfolio receipts (5 agree)

[seathatflowsinourveins]

What

Five independent_session reviews, all agree, of the WSL workstation receipts the foundation lane listed as awaiting review:

• data-alpaca-py install
• data-duckdb install
• data-edgartools use
• data-exchange-calendars use
• skfolio use

Another session recorded them (recorder identity fd125af9…). This session reviewed them (2c7ae79d…), and review and validate both check that the two identities differ.

How the reviews were done (reproduced and adequacy-checked)

Reproduction ran on a clean detached checkout of main at cd17bda. None of the receipts or the files their commands use changed between cd17bda and this branch's base, f5812d3.

• Every recorded command re-ran with its recorded exit code.
• Outputs were byte-identical except uv's self-reported timing line ("Checked N packages in X ms") in five offline uv pip sync --dry-run --offline checks.
• The five git ls-remote tag-to-commit checks were byte-identical. They were run with scripts/host_receipts.py's own run_command and output hash.

Adequacy was checked against docs/contributing-evidence.md §8:

Receipt	Layer role	Positive control	Backed claims	Bound to winner
edgartools use	native HTMLParser parsed a real 2021 8-K offline; Markdown content verified; 0 SEC requests	not required (content-checked parser output); native_document.py raises on a fixture hash mismatch	yes	pin_matches true
exchange-calendars use	XNYS open/close, early close, DST shift, holidays, 252 sessions in 2024, next open; the values agree with the NYSE schedule	a holiday session_open raises NotSessionError	yes	yes
skfolio use	the frozen WalkForward study's stdout is byte-identical (20 folds); MeanRisk invariants; 127 walk-forward folds	infeasible min_weights=0.2 is refused (SolverError)	yes	yes
alpaca-py install	readiness only: builds a LimitOrderRequest in a no-network namespace	n/a (install)	yes	yes
duckdb install	readiness only: the engine's pragma_version() reports v1.5.5, with a source_id that is a prefix of the pin	n/a (install)	yes	yes

Regenerated

• catalogs/landscape/component-evidence-matrix.json and docs/component-evidence-matrix.md.
• catalogs/landscape/new-host-grand-list.json and docs/new-host-grand-list.md.
• The three use receipts' layer pairs move from accepted to host_verified. WSL2 host_verified pairs go from 27 to 32.
• WSL host counts under the dashboard rule: 69 receipts, 56 current agree, 1 needs changes, 0 awaiting review and 12 superseded.

Checks

host_receipts.py validate (98 receipts), validate.py, component_matrix.py --check, new_host_grand_list.py --check, evidence_manifest.py --check and validate_convergence.py --all-recorded all pass.

This is lane:shared because it changes evidence/hosts/** and the matrix and grand list. It regenerates docs/new-host-grand-list.md, so it merges only after the v2026.09.25.2 release window closes and after the foundation lane acks.
