-# A sample workflow which sets up Snyk to analyze the full Snyk platform (Snyk Open Source, Snyk Code,
-# Snyk Container and Snyk Infrastructure as Code)
-# The setup installs the Snyk CLI - for more details on the possible commands
-# check https://docs.snyk.io/snyk-cli/cli-reference
-# The results of Snyk Code are then uploaded to GitHub Security Code Scanning

-# In order to use the Snyk Action you will need to have a Snyk API token.

 - ✅ Native `fetch` used throughout — no new npm dependencies
 - ✅ Graceful degradation: network failure or unrecognised object leaves detail page unaffected
 
+**Mount Mode Support - COMPLETE**: Dual sub-frame folder support (EQ + Alt/Az)
+- ✅ SeeStar names sub-frame folders differently per mount mode: `_sub` (EQ) and `-sub` (Alt/Az)
+- ✅ `catalogParser.js`: detects both `_sub` and `-sub` suffixes; adds `mountMode: 'eq' | 'altaz' | null` to parsed result
+- ✅ `fileAnalyzer.js`: dual sub-folder fields `subFolderEq` + `subFolderAltAz` per object; `mountMode: 'eq' | 'altaz' | 'both'`; backward-compat `subFolder` alias (prefers Eq)
+- ✅ `importService.js`, `mergeService.js`, `diskSpaceValidator.js`: `isSubframeNonFit()` now matches both `-sub` and `_sub`
+- ✅ `fileCleanup.js`: `cleanupSubFrameDirectories()` and `getSubFrameCleanupInfo()` iterate over both sub-folders per object; `deleteSessionFiles()` accepts `subFiles` as `[{ folder, file }]` to support files from two sub-folder paths
+- ✅ `server.js`: `POST /api/cleanup/session` updated — `subFiles` carries per-file folder, `subFolderPath` removed
+- ✅ Dashboard: dedicated **Mount** column in objects table with EQ / Alt/Az / Both badges (colour-coded); mount mode badge in object detail header
+- ✅ Object detail sub-frames section renders one card per sub-folder, each clearly labelled with mount mode
+- ✅ Session file matching (`_getSessionFiles`) searches both sub-folders; returns `{ folder, file }` objects
+- ✅ Delete session sends `subFiles` as `[{ folder, file }]` covering both sub-folders
+- ✅ Sub-frame cleanup confirmation message is mode-aware (lists correct folder suffixes)
+
+**Cosmetic Improvements - COMPLETE**: Dashboard display refinements
+- ✅ Object detail summary cards rendered in compact single-row layout (5 columns, icon + label + value inline)
+- ✅ Sub-frames folder detail grid uses `2fr + 4×1fr` so Files / Size / .fit Files / Other Files stay on one row
+- ✅ Integration Time in object detail banner and objects table falls back to `sum(stackCount × exposure)` from parsed sessions when no sub-frames exist — consistent with the Imaging Sessions table

 **Phase 4 - COMPLETE**: Windows installer & application branding
