Deterministic “random” note IDs (same suffix sequence every session?)

[daikiejp]

I’m using just the default way to generate IDs like timestamp-XXXX in obsidian.nvim.

I noticed that the “random” suffix is not actually random. Every time I restart Neovim, I get the exact same sequence of IDs when creating notes:

Example:
first note → timestamp-USPT
second → timestamp-CRIT
third → timestamp-LOCB
fourth → timestamp-ZSEZ

This sequence repeats consistently across sessions always same suffix.

From what I understand, this might be related to Lua’s math.random() using a fixed seed unless math.randomseed() is set. I fixed with math.randomseed(os.time() + vim.loop.hrtime()) in init.lua

Question
Is this the expected behavior in obsidian.nvim, or am I missing something in the setup?

Should the plugin handle random seeding internally, or is the recommended approach for users to manually call math.randomseed() in the Neovim config?
