Archive 21 implemented triplets whose shipped decisions are complete and whose bodies no longer guide future work (one-off UI chrome, generator applications whose scripts are self-explanatory, superseded implementation detail, process history owned by current contracts/skills). Delete 4 rejected triplets whose premises are obsolete: the DeepReadonly proposal (dev-invariants note now carries the alternative inline), the collapse tool-owned presentation proposal (superseded by the shipped render-intent union), retire-mid-turn-steering (steering is now load-bearing across plan-mode/apiproxy/TUI), and single-session-ACP (automation-only ACP resolved the question; multi-session isolation is pinned by tests). Repair every inbound link: retarget intentional historical citations to archived paths, replace decision-current citations with the surviving authority, and fix the stale example-execute-over-tsx pointer in pnpm-workspace.yaml. Re-record pairing sidecars and seal the archive manifest (append-only; existing seals unchanged).

# Agent Note: User-message IconActions under the bubble

## Problem
|
|
|
|
The chat user bubble had no under-bubble action chrome. The Harness design (figma `User_Bubble/message_container`) shows three IconActions — copy, branch in new chat, and edit — right-aligned under the bubble, matching the product action-bar pattern used elsewhere.
|
|
|
|
## Decision
|
|
|
|
`MessageItem` owns the actions for `kind: 'user'` only. Layout is a column (`align-items: flex-end`, 6px gap): bubble, then a 28px action row with 10px gaps and 28px circular icon buttons (`IconCopyOutline16`, `IconBranchOutline16`, `IconEditOutline16`). Tooltips carry Chinese labels. Actions stay visible by default; `@media (hover: hover)` hides them until the row is hovered or focus-within, so touch / `hover: none` devices keep discoverable controls (opacity alone still hit-tests).
|
|
|
|
Copy writes the bubble's joined text blocks to the clipboard (`navigator.clipboard.writeText`, with an `execCommand` fallback). Branch and edit are present chrome with no handlers yet — they reserve the design seats without inventing session-fork or edit-resubmit behavior.
|
|
|
|
Steering bubbles keep the badge-only form and do not show these actions.
|
|
|
|
## Alternatives considered
|
|
|
|
**Wire branch/edit to real session fork and draft-edit now.** Rejected for this change: those product flows are not specified; shipping inert buttons matches the requested scope and avoids half-built mutation paths.
|
|
|
|
**Always hide with `opacity: 0` outside hover.** Rejected for touch: without `@media (hover: hover)`, idle opacity still hit-tests while looking empty. Hover-capable pointers keep the fade; others keep the actions visible.
|
|
|
|
## Consequences
|
|
|
|
User messages expose copy immediately; branch/edit remain clickable stubs until a later decision owns their behavior. Tests pin the three buttons, copy payload, and steering exclusion.
