## Thinking Path
> - Paperclip orchestrates AI agents for zero-human companies
> - A core part of that is the operator experience around reading issue
state, agent chat, and sub-task structure
> - The current branch had a long run of issue-detail and issue-list UX
fixes that all improve how humans follow and steer active work
> - Those changes mostly live in the UI/chat surface and should be
reviewed together instead of mixed with workspace/runtime work
> - This pull request packages the issue-detail, chat, markdown, and
sub-issue list improvements into one standalone change
> - The benefit is a cleaner, less jumpy, more reliable issue workflow
on desktop and mobile without coupling it to unrelated server/runtime
refactors
## What Changed
- Stabilized issue chat runtime wiring, optimistic comment handling,
queued-comment cancellation, and composer anchoring during live updates
- Fixed several issue-detail rendering and navigation regressions
including placeholder bleed, local polling scope, mobile inbox-to-issue
transitions, and visible refresh resets
- Improved markdown and rich-content handling with advisory image
normalization, editor fallback behavior, touch mention recovery, and
`issue:` quicklook links
- Refined sub-issue behavior with parent-derived defaults, current-user
inheritance fixes, empty-state cleanup, and a reusable issue-list
presentation for sub-issues
- Added targeted UI tests for the new issue-detail, chat scroll/message,
placeholder-data, markdown, and issue-list behaviors
## Verification
- `pnpm vitest run ui/src/components/IssueChatThread.test.tsx
ui/src/components/MarkdownEditor.test.tsx
ui/src/components/IssuesList.test.tsx
ui/src/context/LiveUpdatesProvider.test.tsx
ui/src/lib/issue-chat-messages.test.ts
ui/src/lib/issue-chat-scroll.test.ts
ui/src/lib/issue-detail-subissues.test.ts
ui/src/lib/query-placeholder-data.test.tsx
ui/src/hooks/usePaperclipIssueRuntime.test.tsx`
## Risks
- Medium: this branch touches the highest-traffic issue-detail UI paths,
so regressions would show up as chat/thread or sub-issue UX glitches
- The changes are UI-heavy and would benefit from reviewer screenshots
or a quick manual browser pass before merge
## Model Used
- OpenAI Codex coding agent (GPT-5-class runtime in Codex CLI; exact
deployed model ID is not exposed in this environment), reasoning
enabled, tool use and local code execution enabled

Increased min-height from 144px to 384px on project workspace and from
128/192px to 256/384px on execution workspace so the JSON field is
comfortable to edit inline.

## Thinking Path
> - Paperclip orchestrates AI agents for zero-human companies.
> - Board users and agents collaborate on issue-scoped documents such as
plans and revisions need to be trustworthy because they are the audit
trail for those artifacts.
> - The issue document UI now supports revision history and restore, so
the UI has to distinguish the current revision from historical revisions
correctly even while multiple queries are refreshing.
> - In `PAPA-72`, the newest content could appear under an older
revision label because the current document snapshot and the
revision-history query could temporarily disagree after an edit.
> - That made the UI treat the newest revision like a historical restore
target, which is the opposite of the intended behavior.
> - This pull request derives one authoritative revision view from both
sources, sorts revisions newest-first, and keeps the freshest revision
marked current.
> - The benefit is that revision history stays stable and trustworthy
immediately after edits instead of briefly presenting the newest content
as an older revision.
## What Changed
- Added a `document-revisions` helper that merges the current document
snapshot with fetched revision history into one normalized revision
state.
- Updated `IssueDocumentsSection` to render from that normalized state
instead of trusting either query in isolation.
- Added focused tests covering the current-revision selection and
ordering behavior.
## Verification
- `pnpm -r typecheck`
- `pnpm build`
- Targeted revision tests passed locally.
- Manual reviewer check:
- Open an issue document with revision history.
- Edit and save the document.
- Immediately open the revision selector.
- Confirm the newest revision remains marked current and older revisions
remain the restore targets.
## Risks
- Low risk. The change is isolated to issue document revision
presentation in the UI.
- Main risk is merging the current snapshot with fetched history
incorrectly for edge cases, which is why the helper has focused unit
coverage.

Agent configuration edits already had an API path for replacing the full adapterConfig, but the edit form was still sending merge-style patches. That meant clearing the last environment variable serialized as undefined, the key disappeared from JSON, and the server merged the old env bindings back into the saved config.
Build adapter config save payloads as full replacement patches, strip undefined keys before send, and reuse the existing replaceAdapterConfig contract so explicit clears persist correctly. Add regression coverage for the cleared-env case and for adapter-type changes that still need to preserve adapter-agnostic fields.
Fixes#3179
