Reloadable auto_compact_threshold

What it does

Lets the /plugin dialog's Reload pick up a changed auto_compact_threshold without a restart, with the context meter and /context reading the same value.

Source

ganja-code-6ojt (auto_compact_threshold reloadable without a restart).

The bead is closed when this issue is published, with its external reference pointing here (#38).

File and line references in this issue are to main as of 75a7a92.

Against the three criteria

• Direction (README): The README says nothing about compaction or resuming.
• Today's terminal users: The value is read once, when the engine is built (D566). The bead itself calls it low priority: the key is set once per machine in practice.
• Evidence: The D566 review accepted the restart as a known limit; no report asks for more.

Depends on

No other idea. It needs a sixth D474 reload seam (an atomic is enough) and an amendment to RELOAD_SPLIT (crates/ganja-tui/src/app.rs:267) with its pinned test.

Theme: #56

Start by inspecting the reload seams and the RELOAD_SPLIT amendment in crates/ganja-tui/src/app.rs:267, then trace where auto_compact_threshold feeds the context meter and /context. Add the sixth reload seam and update its pinned test so the /plugin Reload action uses the changed value without a restart.
