Fixed

• asset create --override no longer deletes the existing asset before checking the local file - The existing asset was deleted first and the local file was only validated by the upload that followed, so a mistyped filename (or an unsupported extension, a 413, a dropped connection) destroyed the customer's asset and its metadata with no way back. The local file is now checked before anything destructive happens, and if the re-upload still fails after the delete, the deleted asset's UUID and any metadata captured for --restore-metadata are printed so they can be recovered by hand.
• folder list --folder-uuid now lists that folder - The argument was accepted by the parser and never read, so the command silently listed the tenant root instead.
• The banner no longer corrupts command output - It was printed to stdout whenever any argument equalled help, -h or --help, including values: env list --name help or asset text-match --text help emitted ASCII art ahead of their JSON. The banner is now shown only above genuine help output, as decided by the argument parser.
• --threshold is validated as a percentage - Values outside 0-100 are rejected at parse time on every matching command (--threshold 500 used to go straight to the API; --threshold -5 failed with a misleading "unexpected argument"). A value below 1, almost always 0.85 typed for 85%, is still accepted but produces a warning saying what it actually asks for.
• --concurrent is validated on every command, so --concurrent 0 no longer hangs - asset create-batch sized its semaphore from the flag with no range check, and zero permits made every upload wait forever with no output. The folder match commands only rejected an out-of-range value after resolving the tenant. All concurrent commands now share one parser that accepts 1-10.
• The install page links to the right repository - docs/src/installation.md pointed the installer script, the release page, the clone URL and the issues link at github.com/physna/pcli2, which is not this project.

Changed

• CI is green again on the current stable toolchain - clippy 1.98 flags every Result<_, CliError> as result_large_err because the CSV writer error embedded in the error enums was several hundred bytes wide. That variant is now boxed in both FormattingError and CliActionError; nothing user-visible changes.
• Dependency lockfile refreshed - Clears the h2 advisory (RUSTSEC-2026-0258, reachable through reqwest in the shipped binary) and the rand and event-listener unsoundness advisories reported by cargo audit.
