# aerc Inline Images — Session Context

## Git State
- Branch: `feat/inline-images` (12 commits on top of pristine 0.20.0)
- Remote: `git.sethpc.xyz/Seth/aerc-inline-images`
- All tests pass, builds clean

## Config State (reverted to stock)
- `~/.config/aerc/aerc.conf`: `text/html=html-unsafe` (system default)
- To re-enable images: change to `text/html=html-kitty-unsafe`
- Custom filter at `~/.local/libexec/aerc/filters/html-kitty` (backup at `.backup/`)
- Logging disabled (`#log-file=`, `#log-level=info`)

## Key Discovery: Filter Output Interception
The spec's architecture was wrong. OSC markers are in filter stdout, not pv.source.
Fix: buffer filter.Stdout in attemptCopy(), run ExtractImages on buffer.

## Key Discovery: Vaxis Sixel Crash
`vaxis.(*Sixel).Resize()` spawns a goroutine that panics in go-sixel on certain dimensions.
Cannot be caught with defer/recover (different goroutine). Only affects non-Kitty terminals.
Kitty protocol path is stable.

## What Needs Work
1. HTML rendering quality — composite view is bare text, no pager features
2. Study existing TUI image viewers for better rendering patterns
3. Token auto-refresh for IMAP OAuth
