Summary

This PR executes three focused items from the solana-program-examples audit vs. the latest solana-finance skill (https://github.com/quicknode/solana-finance-skill):

• Fix testing documentation and commands: CONTRIBUTING.md, root README, and many anchor example READMEs now correctly document the actual commands and layout.

  • Anchor: anchor test (or cargo test) from the .../anchor/ dir. Tests live in programs/<name>/tests/.
  • Quasar: cargo test (or quasar test). Tests live in src/tests.rs (per Quasar.toml).
  • Removed the incorrect universal "run pnpm test from the subdir" guidance and fixed prerequisite text.

• Enforce transfer_checked uniformly in Quasar token paths (documentation + prep): Investigation confirmed quasar_spl .transfer(...) is the raw/unchecked form while .transfer_checked(..., mint, ..., decimals) is the safe equivalent (already used correctly in lending and external-delegate Quasar code).

  • Ready-to-apply patches for the finance examples (escrow, token-swap, token-fundraiser) plus the required Accounts changes for the fundraiser mint are recorded in the committed ACTIVE-AUDIT-ITEMS.md.
  • Anchor twins already use transfer_checked.

• Clean legacy / inconsistent artifacts (markdown portion): Removed active references and links to the deprecated solana-developers/program-examples (and professional-education) in credits and docs per the skill rules. ACTIVE-AUDIT-ITEMS.md contains the exact steps + commands for deleting the orphan tokens/.../allow-block-list-token/anchor/tests-rs/ directory and stripping stale bankrun/validator comments from a few Anchor.toml files.

All landed changes are documentation / reference cleanup. The ACTIVE-AUDIT-ITEMS.md file committed with the PR serves as the detailed record and patch source for the remaining non-markdown parts of the three items.

Changes

• 16 files (15 docs + 1 new audit scope file)
• Pre-commit biome formatting applied cleanly.
• No program behavior changes.

Test plan

• Commit succeeded with lint-staged + biome --write on all changed files.
• From updated anchor directories (e.g. basics/counter/anchor, finance/token-swap/anchor, basics/hello-solana/anchor): anchor build && anchor test (or plain cargo test).
• Confirm Quasar READMEs (counter, escrow, etc.) still correctly say cargo test.
• When applying the prepared patches from ACTIVE-AUDIT-ITEMS.md: run the relevant cargo test (Quasar finance) and anchor test for any touched tomls.
• Root pnpm check / pnpm lint (biome) at repo level if desired.
• Review that no references to the old solana-developers program-examples remain in active docs.

✅ Testing docs/commands aligned
✅ Legacy references cleaned (markdown)
❌ (Prepared) Quasar transfer_checked source changes + orphan dir + toml comments — patches + exact commands in ACTIVE-AUDIT-ITEMS.md
