Module loose 

“Loose” mode for anchor debugger — runs in any cargo workspace without requiring an Anchor.toml.

Anchor projects ship an Anchor.toml that maps program names to deployed pubkeys and pins the cargo test invocation. Bench / research workspaces are plain cargo workspaces that happen to use anchor-lang-v2 as a library — forcing them to author an Anchor.toml just to use the debugger would be friction for no payoff.

This module covers everything the Anchor.toml-driven path provides:

• Workspace root — walk up from cwd looking for the nearest Cargo.toml declaring [workspace].
• Current package — read <cwd>/Cargo.toml for the [package] name.
• Test invocation — cargo test --features profile -p <pkg> from the workspace root.
• Program → ELF map — pair target/deploy/*.so with the matching *-keypair.json to recover the deployed pubkey.

Sanity checks fire as early as possible so the user gets actionable errors instead of opaque “no traces” messages later.

Structs

LooseWorkspace

Discovered cargo workspace context.

Functions

clear_profile_dir

Wipe the per-test trace dir before a fresh run so stale traces from a previous session don’t leak into the new picker. Idempotent — missing dir is fine.

discover_programs

Walk the workspace’s SBF build artifacts and return a base58 program-id → .so path map. Two location families are considered:

run_cargo_test

Run cargo build-sbf -p <pkg> from the workspace root. This produces the post-linked .so + sibling keypair under target/deploy/ that solana-sbpf can parse — the raw cargo build --target sbpf-solana-solana artifact in target/sbpf-solana-solana/release/ is missing relocation metadata our debugger needs.
