    v0.3.7 Stable

    0.3.7 — runtime footprint trims

    What the plugin holds while the game runs, after a symbol-level pass over the 0.3.6 ELF:

    • Diagnostics thread stack 2 MiB → 256 KiB. The Switch std gives every Rust thread a 2 MiB stack from the game heap unless the spawner sets one; Deluxe never did. About 1.75 MiB of heap back for the whole run. Hardware check: heartbeats keep arriving in hang-trace.log, no crash report naming deluxe-diagnostics.
    • Pia RTT station table allocated on first use. The 107 KB table (253 stations × 100-sample ring) lived in .data; it is now allocated by the diagnostics poll after the first RTT sample of the process and never exists offline. Until it exists the overlay shows exactly what an empty table shows (tested).
    • API trace chunks 4096 → 2048 rows (80 KiB .bss); still ~1.9 s per chunk at the measured hardware rate against the 500 ms drain.
    • Callback capture buffer (64 KiB) allocated per capture and freed after export; the render path still never allocates.

    Sections .text 1402336 / .rodata 343120 / .data 69912 / .bss 138672; resident image 1.95 MB (0.3.6: 2.21 MB). With the stack the steady-state cost drops by about 2.0 MB.

    Not in this release: the embedded imgui backend trims, which are being prepared in the fork intpa/imgui-smash for both the embedded archive and the standalone companion plugin.
