Symbol M_i

The passage around this formula

…these “representative numbers” rather than fixed constants — actual figures move with every project’s own files — but the shape they describe is stable and worth writing down as an identity: $T_{\mathrm{start}} = T_{\mathrm{sys}} + T_{\mathrm{mem}} + T_{\mathrm{env}} + T_{\mathrm{tools}} + \sum_{i=1}^{k} M_i$. where $M_i$ is the token count of the i -th memory file discovered along the walk from the filesystem root to the working directory, summed over however many, k , are found. Every term is committed before the developer types a word. The point is not the specific numbers; it is that $T_{\mathrm{start}}$ is…
