Refuse to resolve any PyPI dependency uploaded in the last 7 days (`[tool.uv] exclude-newer = "7 days"`). Mitigates blast radius of compromised dependencies (typosquatting, account takeovers, dependency confusion). Pins `required-version = ">=0.11.1"` so older uvs fail loudly instead of silently parsing "7 days" as an RFC 3339 date and proceeding *without* the cooldown — see uv#17908. zeroband has no first-party PrimeIntellect packages in its dep closure, so no `[tool.uv.exclude-newer-package]` exemptions are needed. Add the table when that changes. Lock regenerated: uv migrated the lockfile schema from revision 2 to revision 3 (large mechanical churn — 0 packages removed, 0 versions regressed). Schema migration is independent of the cooldown change. Part 1 of 3 in a coordinated supply-chain hardening across PI repos. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

What
Adds
exclude-newer = "7 days"to[tool.uv]so new PyPI uploads are filtered out until they've been on the index for ≥ 7 days.zerobandhas no first-party PrimeIntellect packages in its closure, so no[tool.uv.exclude-newer-package]exemptions are needed yet — the comment inpyproject.tomldocuments when to add one.Why
Most malicious PyPI uploads (typosquatting, account takeovers, dependency confusion) are detected and yanked within hours-to-days. A short cooldown quarantines them at near-zero cost. Part 1 of 3 in a coordinated supply-chain hardening across PrimeIntellect repos.
Notes
uv.lockdiff is large but mechanical: uv migrated the lockfile schema fromrevision = 2→revision = 3. The semantic diff is just the new[options]block recording the cooldown. Zero packages removed; zero version regressions.uv lock --checkpasses locally.tool.uv.dev-dependencies(pre-existing; should migrate todependency-groups.devin a follow-up).🤖 Generated with Claude Code
