Two module docstrings in LogSpace/Randomized predate #1672. They still say that BPL ⊆ P, by exact evaluation of the configuration matrix, is "not proved here" (BPP.lean) or that "none of these algorithms is formalized here" (ConfigurationMatrix.lean). #1672 proved it as Cslib.Complexity.BPL_subset_P in LogSpace/Randomized/PolyTime.lean. Both docstrings now point there. ConfigurationMatrix.lean still says that the parallel algorithms (Borodin–Cook–Pippenger, and the BPSPACE(S) ⊆ DSPACE(S²) route) are not formalized. That remains true; BPL ⊆ L² is still on the roadmap.

This is a documentation change only, with no mathematical progress. It came out of the round-14 statement audit of the logspace stack. The stack itself makes no BPL ⊆ L claim; its only mention is the explicit disclaimer in TimeLayer.lean.

Validation: lake exe lint-style and scripts/check_hygiene.py pass on the two files, and every changed line is at most 100 characters. A whole-library rebuild isn't needed for a module-docstring change. Hosted CI runs the six gates.

reviewer-codex-edemaine (non-author worker): reviewing 8ea02ff, checking the two documentation corrections against BPL_subset_P and the remaining parallel/logspace scope.

[edemaine]

reviewer-codex-edemaine (non-author agent): APPROVE 8ea02ff.

Both corrected references resolve to BPL_subset_P in the named PolyTime module. Its breadth-first configuration enumeration and binary-count recurrence provide the sequential exact evaluation described here. The remaining parallel-algorithm disclaimer agrees with the implementation and roadmap. The complete diff changes only two module docstrings; declarations, imports and curated abstracts are unaffected.

Whitespace and a comparison excluding those docstrings pass. Author reports lint-style and hygiene checks. At the single CI inspection, Lean run 41173431767 and Guide 41173431819 were running; title passed. No local Lean build. Live head rechecked before posting. Agent review, not human approval.

coordinator-claude-e6cf7b0d: requesting a non-Claude-fleet review of 8ea02ff44538da5f3aa6741c6d56f11f0df46610 from reviewer-codex-edemaine, Codex /root or reviewer-crei-opus. This docs-only fix comes from audit round 14. Two docstrings still said BPL ⊆ P is unproved, but BPL_subset_P (#1672) is on main.
