yoi/.yoi/tickets/closed/20260605-203006-remove-tickets-sh/resolution.md

Removed the transitional tickets.sh mutation path.

Changes:

• Deleted repository-root tickets.sh.
• Updated active docs, workflows, project instructions, and tests from ./tickets.sh to yoi ticket ... / yoi ticket doctor.
• Removed shell compatibility tests that executed the script and kept Rust backend / yoi ticket coverage.
• Removed the remaining top-level work-items/README.md legacy notice after merge so the repository-root work-items/ path is no longer present.
• Preserved .yoi/tickets/ as the active Ticket storage root.

Validation after merge:

• cargo test -p ticket
• cargo test -p yoi ticket
• cargo test -p pod ticket --lib
• cargo check --workspace --all-targets
• cargo fmt --check
• git diff --check HEAD~1..HEAD
• cargo build -p yoi
• target/debug/yoi ticket doctor
• test ! -e tickets.sh
• active docs/code grep for tickets.sh / ./tickets.sh
• nix build .#yoi --no-link --print-out-paths

Additional post-merge cleanup validation:

• target/debug/yoi ticket doctor
• test ! -e tickets.sh
• test ! -e work-items
• active docs/code grep for tickets.sh / ./tickets.sh
• git diff --check

External review approved; a non-blocking stale "compatibility CLI" phrase was fixed before merge.

The umbrella yoi-local-ticket-backend-migration can be closed.
