The unpublished line of work joins the sanitized public line
The published line and the local line had no common ancestor: the public one
carried the redaction pass, the local one carried three weeks of corrections
that never shipped. This commit ports the local work onto the public line,
keeps every public redaction, and extends the same discretion to seven client
mentions that were still named in published comments.

Carried: LICENSE year and LICENSING.md; the measured burn figures replacing
the deflation claim (the vault holds ~0.137 AERE of 2.8 billion, and burn is
a share of validator coinbase revenue, which is zero today); 'audited' removed
from next to Bouncy Castle; citation paths rewritten to published form with
CITATIONS-UNRESOLVED.md remeasured 2026-08-11; VERIFY-POLICY.md; slashing and
ownership comments brought down to what the code does; the AerePyth repair;
the shutter test helper the tests cite; runnable package.json entries; the CI
file split into a GitHub/Gitea twin pair with a real measured test-run status;
and the .gitignore hardening written after a compiled artifact leaked a local
path in a sibling repository. A false '2-of-3 multisig' description of the
owner account is corrected to what the chain measures: an externally owned
account. The self-audit findings catalog stays unpublished pending an explicit
decision.

Licensing

Default for this repository: MIT, Copyright (c) 2026 AERE Network. See LICENSE.

That default does not cover every file. Some files here are third-party code vendored in unmodified, and they keep the licence their authors gave them. A few of our own files carry a copyleft header. Where a file has its own SPDX-License-Identifier, that header governs, not the repository default.

This page lists every exception. It was produced by reading the SPDX-License-Identifier line of every file in the tree, not from memory.

Counts, as measured

The exceptions, by path

contracts/zkverify/risczero/ — RISC Zero verifier, GPL-3.0 and Apache-2.0

Vendored from RISC Zero. Two of these files are copyleft. If you redistribute them, or a work derived from them, GPL-3.0 applies to that redistribution regardless of anything this repository says elsewhere.

These four are AERE Network's own work, but they carry an LGPL-3.0-only header. Until the provenance of that header is settled in writing, treat these files as LGPL-3.0-only, which is what their header says. They are not offered under the repository's MIT default.

Why the exceptions are not simply relicensed

Two reasons, and they point in opposite directions.

The vendored files are other people's copyright. We have no power to relicense them, and a repository-level notice claiming otherwise would be false rather than generous.

The contracts/mpc/ files are our copyright, so we could relicense them, but the direction of that change matters. Rewriting a copyleft header to a permissive one is only safe if the file is not derived from copyleft code. That has not been established for these four, so the header stands.
