 * Current Session State
 
 ** What We're Working On
-Testing unattended installation with --config-file option. Currently running 2-disk mirror test.
+All 3 unattended installation tests completed successfully.
+
+** Bugs Found and Fixed This Session
+
+*** Bug 1: gather_input returns non-zero exit code
+- Cause: `[[ -n "$WIFI_SSID" ]] && info "..."` returns 1 when WIFI_SSID is empty
+- The bare `return` inherits this exit code
+- With `set -e`, script exits immediately
+- Fix: Changed `return` to `return 0`
+- Commit: 2f5bb37
+
+*** Bug 2: pacstrap hangs on provider prompts
+- Cause: pacstrap prompts for package provider selection (iptables, initramfs)
+- In unattended mode, no input is available
+- Fix: Pipe `yes ""` to pacstrap to auto-select defaults
+- Commit: 1dc4e95
+
+*** Bug 3: fsck hook in mkinitcpio
+- Cause: fsck hook was included in HOOKS for ZFS root
+- ZFS doesn't use fsck, causes error messages
+- Fix: Removed fsck from HOOKS line
+- Commit: 1dc4e95
+
+*** Bug 4: Missing hostid for ZFS boot
+- Cause: ZFS uses hostid to identify pool ownership
+- Without hostid, pool import can fail
+- Fix: Generate/copy hostid and add spl.spl_hostid to kernel cmdline
+- Commit: 1dc4e95
+
+** Testing Status
+- Test 1: 2-disk mirror - PASSED (installation complete, boots to passphrase prompt)
+- Test 2: 2-disk stripe - PASSED (installation complete)
+- Test 3: Single disk - PASSED (installation complete)

 - Config only used when explicitly specified (prevents accidental disk wipes)
 - Example config at /root/install-archzfs.conf.example on ISO
 - Validates required fields: HOSTNAME, TIMEZONE, DISKS, ZFS_PASSPHRASE, ROOT_PASSWORD
-- Sets sensible defaults for optional fields
 
 *** Boot Fixes for ZFS
-- Removed fsck from mkinitcpio HOOKS (ZFS doesn't use fsck)
+- Removed fsck from mkinitcpio HOOKS
 - Added hostid generation/copy to installed system
 - Added spl.spl_hostid to kernel command line
 - Removed 'quiet' from kernel params for visible boot messages
 
-*** Multi-Disk RAID Support
-- RAID level selection: mirror, stripe, raidz1/2/3
-- EFI partitions on all disks for boot redundancy
-- Stripe option for max capacity (no redundancy)
-- Dynamic capacity calculations in preview
-
-*** fzf-Based User Interface
-- Replaced all select menus with fzf fuzzy finder
-- Timezone: fuzzy search with current time preview
-- Locale: all locales shown, format examples in preview
-- Keymap: all keymaps with layout info
-- Disk selection: multi-select (TAB), disk details preview
-- RAID level: explanatory preview with capacity calculations
-- WiFi: network list by signal strength, security info preview
