v0.99.98

This release is largely about filament: a new on-printer product-edit workflow for
building your own catalog, correct OrcaSlicer material matching so synced spools land on
the right preset, and automatic repair of mislabeled slots. It also sharpens print-status
reporting (M117 messages and layer/ETA accuracy), adds automatic ZMOD z-offset
persistence, and clears a cluster of crashes and small-screen layout issues.

Added

• Build your own filament catalog — a new product-edit modal lets you add and edit filament products right on the printer. Your entries live in a user overlay that survives catalog regeneration, so updates never wipe them. (#1120)
• Automatic ZMOD z-offset persistence — on printers with a ZMOD probe, HelixScreen enables persistent z-offset on connect, so a calibrated offset survives restarts instead of resetting.
• M117 messages on more screens — status messages set via M117 now appear on the idle card and during pre-print heating, QGL and purge, not only mid-print.

Fixed

• Filament synced to OrcaSlicer with the wrong material — a slot set to a specific type like ASA-GF came across in OrcaSlicer as "Generic PLA", putting PLA temperatures on glass-filled ASA. HelixScreen now sends OrcaSlicer the closest name it does recognize (ASA-GF → ASA), so it picks a correct preset, while your printer's own screen keeps showing the precise name. A truly unknown material syncs with its color and temperatures but no material selected, rather than a wrong guess. Existing slots are repaired automatically the next time HelixScreen starts.
• WiFi wizard crash during backend startup on Pi (bundle WWZE4K9T) — WifiBackendWpaSupplicant::stop() captured a local std::promise by reference into a deferred runInLoop lambda, then returned and destroyed it when its wait timed out; the queued cleanup later called into freed memory and crashed at PC=0x0. The promise is now held in a shared_ptr captured by value, so it outlives the deferred completion.
• Filament mapping showed unused tools — the print filament-mapping card listed every tool on the palette; it now shows only the tools a print actually uses, and no longer suppresses the material-mismatch warning for used-but-unresolved slots.
• Garbage layer and ETA during print start — fabricated layer/ETA figures are now gated on print duration, so they stop flashing nonsensical values during PRINT_START.
• M117 handling during prints — messages are cleared at print end rather than print start, are no longer clobbered by routine status deltas, and no longer leak into the phase-label line.
• Camera stayed live across network changes — the K2 webcam is registered with a relative URL, immune to DHCP lease changes and eth/wlan interface flips that previously stranded a baked-in IP.
• Several crashes — scroll-container repopulate use-after-free (#1123), a temperature-graph observer race during deferred delete (#1117), hot-reload rebuild of the print-file detail overlay, and duplicated side-effects when reconnecting to unchanged hardware (#1117).
• AD5X filament loading — corrected gcode-path TYPE=/HEX= extraction and made the loading-time budget swap-aware. (#1065)
• Small-screen history filter — the history filter row collapses on small screens (Snapmaker U1) with an active-filter funnel indicator. (#1116)
• Pre-print options — toggles gated on a macro that isn't installed are now hidden instead of doing nothing. (#1122)
• Touch, fans, installer — released touch slots keep their coordinates instead of zeroing; a fan's .part role falls back to the front-most named fan; installer architecture validation reads the ELF header without dd.

Changed

• Inputs scale on larger screens — text fields, dropdowns and toggles use a responsive height so they aren't cramped on big displays; small screens keep the compact 48px size.
• No more source comments on outgoing gcode — HelixScreen no longer annotates M117/M118 and other commands with a "; from helixscreen" comment that some firmware echoed back into the console. (bundle A2TPH5V2)
