Graph incidence matrix builder
Implements the signed posting matrix \(P\), validates 1ᵀP = 0, and exposes sparse CSR representations for downstream PDE mappings.
Open sanitized file →Source Code Access & Review Process
Private repository access is restricted to protect issuer data, but reviewers receive structured entry points: sanitized module excerpts, build metadata, and a documented request workflow.
Why the Git repository is private
- Client filings: Working papers reference non-public registrant data extracted from PCAOB engagements.
- PII in audit logs: Reviewer and engagement-team identifiers are embedded in several test fixtures.
- Export-controlled research: PDE tooling includes Laplace-domain extensions currently under peer review.
Because of those constraints, all public links now direct here instead of throwing a 404 on GitHub. Reviewers still receive the same evidence, just via controlled delivery.
Access request workflow
- Email nirvanchitnis@gmail.com with your organization, review scope, and deadline.
- NDA acknowledgement (one-page). Turnaround < 1 business day.
- Delivery: a read-only Git bundle + SHA256 checksum, plus optional Zoom walkthrough.
- Revocation: bundles expire after 30 days unless an extension is requested.
Reviewers from audit firms have already been onboarded; referencing the engagement code in your email lets us reuse the approval.
Sanitized module excerpts
The most frequently cited file (src/graph/incidence.py) now has a static HTML snapshot so reviewers can confirm the discrete conservation logic without cloning the repo.
Future snapshots
Additional modules (Laplace solvers, empirical validators) can be exported on request. Mention the path(s) you need when emailing.
Build metadata
- Current release tag
acf-v2.3.0(November 2025)- Commit hash
f7f0b0b05d500a3149f6b539f84ac7ea0660a7b6(available in every bundle manifest)- Verifier
- Reproducibility suite (
tests/test_equity_bridge.py,tests/test_leverage_identity.py)
When you receive a bundle you can run git fsck and compare the SHA above to the manifest entry. All artifacts also include a BUILD.md file summarizing the dependency freeze.
