Conversation
The Telegram module sends ctx.reply(text) with no parse_mode, so the DA's **bold**, *italic*, `code`, code fences, and links arrive as literal characters on the phone. The existing TELEGRAM MODE OVERRIDE prompt worked around this by steering the DA toward plain prose — a render-side problem masquerading as a content-side restriction. Changes: - New `mdToHtml` helper in modules/markdown-html.ts converts a useful subset of markdown to Telegram HTML: bold, italic, strikethrough, inline code, fenced code, links, ATX headers (→ bold lines), bullets (→ '•'). - Telegram module sends with parse_mode: 'HTML' by default; plain-text fallback on any send error via .catch(). - New `markdown_mode: "html" | "plain"` field in TelegramConfig, defaults to 'html' — opt-out preserved for users who want raw text. - TELEGRAM MODE OVERRIDE prompt flipped from 'no formatting' to an inline cheatsheet of what renders, so the DA writes naturally- formatted prose. Robustness: - Code blocks are stash-and-restored before other transforms run — bold/italic cannot leak into them. - Italic boundaries admit punctuation, whitespace, and HTML tag chars so '**a _b_**' nests correctly while 'snake_case' and 'Array<T>' survive untouched. - Unbalanced markers degrade to literal characters, so chunk-splitting at the 4096-char boundary cannot produce broken HTML. Tests: $ bun test ./Releases/v5.0.0/.claude/PAI/PULSE/modules/telegram.test.ts 21 pass, 0 fail End-to-end validation: showcase message exercising every transformation sent through @nairyo_bot; renders correctly on iOS.

Relationship to other open PRs
v2 — per-thread sessions, live tool reactions, empty-response recovery) — no functional overlap on markdown rendering. feat(pulse/telegram): v2 — per-thread sessions, live tool reactions, empty-response recovery #1281 setsparse_mode: "Markdown"on its/help,/status, and/threadscommand-output text only, not on the DA's actual replies, and uses the legacy Telegram Markdown mode (no nesting, no underscores-in-identifiers safety). This PR adds proper HTML rendering of the DA's prose with a regex-tested converter and a plain-text fallback. The two PRs do sharemodules/telegram.tsand would file-conflict on merge — whichever lands second will need a rebase, but the conceptual scopes are orthogonal.
