Record Manager — starter template

Clean, best-practice starting point for the CS 2060 cumulative project. Pick a flavor (contacts / gradebook / expense tracker) and extend it milestone by milestone; do not delete the verification targets.

Before your first commit: read SETUP.md (toolchain) and AGENTS.md (the rules every coding agent reads), copy MILESTONE.md per milestone as your write-up.

Layout

include/record.h   the record_t struct + record_new/record_free + status codes
src/record.c       record implementation
src/main.c         CLI menu (Milestone 1)
tests/smoke.sh     dependency-free smoke tests for the CLI
Makefile           build + test + sanitizer targets
.clang-format      enforced formatting (clang-format -i src/*.c include/*.h)

Targets

Command	What it does
`make`	build `build/recman` (`-std=c17 -Wall -Wextra -Wpedantic -Werror -g`)
`make test`	run the smoke tests
`make sanitize`	rebuild with ASan+UBSan and run the smoke tests
`make valgrind`	run under Valgrind Memcheck (leaks → non-zero exit)
`make clean`	remove `build/`

Milestones

The five-milestone spec (M1 CLI → M2 buffer → M3 list → M4 file → M5 refactor) lives in ../README.md (the assignments/projects/ folder).

AI use (optional)

AI assistance is not required. If you use it, the standard AGENTS.md in this repo tells the agent exactly what Tier 2 permits; state "AI used: none | Tier 2" at the top of each milestone write-up and let the verification gates (make test / make sanitize / make valgrind + the CI report) be the record. retest 1787710392
