Edit existing posts + cover images in /write portal - #11
Merged
Conversation
Cover: pick an in-post image or upload one; stored once, used as the social/OG card and an optional post hero. Edit: each export writes a .write-source.json sidecar next to the post; 'Edit a published post' dialog fetches it plus the original images from GitHub raw and reloads them losslessly into the editor. Original publish date preserved, updated date stamped on re-export.

What
Two features for the
/writeportal.Cover image — pick an image already placed in the post or upload a new one, at the bottom of the meta form. Stored once, written to frontmatter as
cover: ./x, bundled in the ZIP, used as the social/OG card and rendered as an optional hero atop the post.Edit an existing post — every export now also writes a hidden
.write-source.jsonsidecar (the exact editor doc + meta + table styles) next to the post. An "Edit a published post" dialog takes the post URL, fetches that sidecar plus the original image bytes from GitHub raw (open CORS, individual files — no repo/folder download), and reloads everything losslessly into the editor. Original publishdateis preserved;updated:is stamped on re-export. Missing sidecar → clean error, never corrupts.Files
