 - **utmpx time field portability** — replaced hardcoded `C.__uint32_t` / `C.__int32_t` casts with a C helper function (`auth/utmpx_time.h`) that lets the compiler handle type conversion. fixes build failure on systems where `ut_tv` uses `struct timeval` instead of the 32/64 compat struct
 - **cgo pointer safety for pam** — replaced `unsafe.Pointer(&h)` (Go stack pointer passed to C) with `storeHandle`/`loadHandle` helpers that keep the `cgo.Handle` in C-heap memory. fixes `cgo argument has Go pointer to unpinned Go pointer` panic on Go 1.22+
+- **pam conversation callback** — fixed `unsafe.Slice` using `&r` (pointer-to-pointer) as the backing array instead of `r` (the calloc'd response array), which wrote password bytes into random stack memory. also now only responds to `PAM_PROMPT_ECHO_OFF`/`PAM_PROMPT_ECHO_ON` messages — info and error messages get nil. fixes `pam_unix: auth could not identify password`
+- **makefile `enable` and `update` targets** — `make enable` stops any running DM, disables the aliased display-manager, and enables latchd. `make update` runs uninstall → git pull → reinstall in one command
 - **missing `extra/` directory** — added `extra/config.toml`, `extra/xsetup.sh`, `extra/lemurs.pam`, and `extra/lemurs.service` so `make install` can find them
 - **makefile `deps` target** — added `make deps` to automatically install `libpam0g-dev` and `build-essential`, and verify go is present
 - **readme overhaul** — rewrote for clarity: added "what problem does this solve", "how it works", known issues, simpler install instructions, and proper dependency listing
