Built Applications Reference knowledge hub for Tech - shortcuts/commands/Q&A by platform (freecommander, server, existing windows/android) plus a separate installed-apps inventory DB. Wired both into backend and frontend nav. Filed a server-improvement task and took a fresh platform snapshot.

1) Extended lab-api.php with add_shortcut/add_command/add_qa/list_platforms actions (backup taken first) - reused laboratory.db instead of forking a new DB per USR369 direction. 2) Seeded freecommander platform (3 QA: font size, duplicate Downloads folder fix, quick view panel position-unconfirmed). 3) Seeded server platform (11 QA sourced from Server 40's own knowledge-40.md/directive-40.md/jurisdiction-40.md - backend directory structure, deploy safety rules, records.db trap path, backup retention rule, DB schema gotchas, auth gate, transfers API location, WAF timeout behavior, web-fetch.php status, CHECKPOINT handoff bug). 4) Built separate apps_inventory.db + inventory-api.php (device/name/category/version/purpose/notes) - segregated by design from troubleshooting knowledge. Seeded 3 Computer entries (FreeCommander XE, Google Drive for Desktop, FreeFileSync). 5) Built apps-hub.html viewer page, tabbed by platform, pulling live from both APIs. 6) Linked apps-hub.html from backend/index.html (Tools section) AND frontend/30-Tech/index.html (apps section, which had been missed initially and caught on follow-up) - backups taken before both edits. 7) Filed T725 to Server 40 - memory-pipeline-api.php missing update_tags action (found while trying to tag existing knowledge entries applications:yes/no). 8) Added D690 standing directive to directive-30.md (confirmed correct decade-suffix path, not code-suffix) - auto-log future troubleshooting Q&A/shortcuts in-session going forward. 9) ARTIFACTS-30.md updated across 4 append cycles, also caught Laboratory and Factory apps which existed live but were never registered there before this session. 10) Fresh full-platform SNAPSHOT taken 6:35pm PT (2475 files, 25.7MB zipped) to capture all session changes, after confirming morning's snapshot predated the work.
