Change

Letta Code panes (agent kind letta, offered since #1815, Chat in #2312) drew the fallback mark: the
initial "L" in a disc, in the sidebar, the agent picker, the pane title and the composer.

This adds letta to AGENT_SVG_MARKS. The glyph is the vector path of Letta's own favicon
(https://docs.letta.com/favicon.svg), rounded to one decimal like the other marks, on the blue tile
(#0707AC) with the grey glyph (#C9CDD1) of Letta's app icon, at the same proportion (glyph half the
tile). It carries brand fills, so Settings → Appearance → Agent logos → Mono greys it like the others.

• src/components/agentSvgMarks.ts: the letta entry, and its source in the header comment.
• THIRD_PARTY_NOTICES.md: letta joins droid and maki as a mark that does not come from LobeHub Icons.
• src/components/AgentMark.test.tsx: letta is among the marks with brand colors.
• changelog.d/letta-agent-mark.md.

Part of #1730.

Validation

• bun run check fast on these files: workflow syntax, generated types and themes, typecheck, build, unit
  (8877 pass, 0 fail, 35 skip) and actionlint all ok. That run was invalidated only because the commit
  was made while it ran (same file contents); a rerun on the committed tree follows below.
• Rendered with the Vite client against a herdr 0.9.5 server with nine Letta Code panes: every Letta row,
  the pane title and the composer drew the new mark (14 .agent-mark.letta, no fallback initial), no
  page errors. Checked at 16 px and 64 px.

Full details: Title check

Explanation

The title 'feat(agents): draw Letta Code's own mark instead of the fallback initial' matches the main change. The PR adds a dedicated 'letta' entry to AGENT_SVG_MARKS so Letta Code panes show Letta's mark instead of the fallback 'L' disc. The title is concise, specific, and uses a conventional-commit style prefix.

Full details: Description check

Explanation

The description follows the repository template. It has a '## Change' section that describes the problem (Letta Code panes showed the fallback 'L' disc), the resulting behavior, and the files touched, and it links the related issues (#1730, #1815, #2312). It has a '## Validation' section that lists the commands run (bun run check fast) with results and a rendering check against a herdr server. The template asks for a maintainer-agreed issue link for features. The description references #1730 as 'Part of', which may or may not be the maintainer-agreed issue, so the author should confirm that link. Contract-test coverage is not mentioned, but the change does not touch HTTP/WS code, so this is not required.

Full details: Docstring Coverage

Explanation

No eligible functions found in the changed files. Skipping docstring coverage check. Docstring coverage is scoped to functions touched by this diff with cyclomatic complexity of at least 2. Documentation-only edits and deletions within surviving functions are included; unchanged diff context and fully deleted functions are excluded. Analyzed 0 functions across 2 files. (2 skipped: 2 unsupported.)

Merging 82da80a, thank you @homebodify! Letta Code's agent tiles and pickers now draw its own mark (its official favicon glyph) instead of the fallback initial, through the existing agent-mark registry; the monochrome style uses the existing grayscale treatment. Strict external review by the merge pass: every changed file read, the SVG carries no script, external reference or handler; it follows the pattern and attribution of the other vendor marks; 36 tests, conventions and typecheck pass. The maintainer delegated the per-PR look check and judges the final build before the release. Attribution matches the other non-LobeHub marks (droid, maki): the source is named in agentSvgMarks.ts and letta is excluded from the LobeHub notice; CodeRabbit's two Minors on attribution/DESIGN.md were answered on that basis.
