Summary

This PR adds a comprehensive Markdown to HTML converter for the Telegram channel, enabling rich text formatting in messages sent to Telegram. The converter transforms standard Markdown syntax into Telegram's supported HTML tags, providing users with better formatted responses.

Motivation

Currently, the Telegram channel sends plain text messages without any formatting. This limits the readability and visual appeal of responses, especially for structured content like tables, code blocks, and emphasized text.

With this change, LLM responses written in Markdown will be automatically converted to Telegram-compatible HTML, improving:

  • Readability: Bold, italic, and strikethrough text for emphasis
  • Code presentation: Proper code blocks with syntax highlighting support
  • Table formatting: Clean tabular data display
  • Quotes: Blockquote support for citations
  • Links: Clickable URLs

Technical Details

Conversion Rules

All conversions follow Telegram Bot API HTML style:

Markdown Telegram HTML Status
# Header <b>Header</b>
**bold** <b>bold</b>
*italic* <i>italic</i>
~~strikethrough~~ <s>strikethrough</s>
`code` <code>code</code>
```python code ``` <pre>code</pre>
> quote <blockquote>quote</blockquote>
|col1|col2| col1\tcol2
- item • item
--- ──────────
[text](url) <a href="url">text</a>

Special Features

  1. Multi-line quote merging: Consecutive > lines are merged into a single <blockquote> tag
  2. Table header bolding: First row of tables is automatically bolded
  3. Cell-level formatting: Table cells support inline styles (bold, italic, etc.)
  4. Code block HTML escaping: Special characters in code blocks are properly escaped
  5. Robust code fence detection: Supports code fences anywhere in a line (e.g., [prefix] ```code``` )
  6. Graceful fallback: HTML parse errors fall back to plain text sending

Testing

All tests pass (28/28, excluding 1 pre-existing unrelated failure):

Remove 50 build artifact files from source control.

The src/copaw/console/assets/ directory contains 50 JavaScript files with content hashes in filenames (e.g., chunk-4BX2VUAB-BEvcyVQL.js, pieDiagram-ADFJNKIX-B2m5RLpk.js), which are build artifacts generated by a bundler. Your project's own .gitignore already excludes src/copaw/console/dist/ with the explicit policy: "Console frontend build (generated in Docker/CI, do not commit)". The assets/ directory violates this same policy.

Add src/copaw/console/assets/ to .gitignore and regenerate these files during the CI/CD build step, or if intentional, update the .gitignore comment to clarify the exception.

.node-icon-${r-1}, .section-edge-${r-1}, .edge-depth-${r-1}) which misaligns
sections with the renderer's section-1/section-2 naming; change all occurrences
of r-1 to r so class names match the renderer. Also clamp the computed edge
stroke width (p), which currently can become non-positive (from expressions like
17 - 3*r); compute p using a clamp/Math.max to ensure a minimum positive stroke
(e.g., p = Math.max(1, 17 - 3*r)) so .edge-depth-${r} stroke-width stays valid.

HTML chunking with newline/space boundaries can break tags; fallback masks the inefficiency.

_chunk_text splits on the last newline or space within chunk size, with no awareness of HTML structure. If a split point falls inside an HTML tag (e.g., <a href="..."> or <code>), the chunk becomes malformed. Telegram rejects unbalanced HTML with BadRequest: can't parse entities.

The current code catches this and retries as plain text, which prevents message loss but wastes an API call. To improve efficiency, either:

  1. Use HTML-aware chunking that preserves tag boundaries, or
  2. Switch to entity-based formatting (entities= parameter) instead of parse_mode="HTML" to avoid HTML parsing altogether.

Handle file:// audio payloads before calling send_audio.

Audio content is normalized to file://... upstream (like image/video/file), but the audio branch forwards data directly without checking for the file:// prefix. In contrast, image, video, and file branches all explicitly check for file:// URIs, extract the local path, and pass a file object to their respective send methods. Since Bot.send_audio() does not support file:// URIs, audio sends will fail when content is stored as file:// URLs. Convert file:// paths to file objects before calling send_audio, matching the pattern used by other media types.

Fix .gitignore to properly exclude console frontend build outputs.

The .gitignore file (line 16) explicitly states that console frontend builds are "generated in Docker/CI, do not commit", but the exclusion pattern is misconfigured. It currently specifies src/copaw/console/dist/, but the Vite build configuration outputs directly to src/copaw/console/. This causes generated chunk files and assets (like chunk-TZMSLE5B-DB6V8Dki.js) to be committed to version control.

Update the .gitignore pattern to properly exclude the frontend build output directory, or verify that the source files should remain committed while build artifacts are regenerated during CI/deployment.

Remove build artifacts from version control or update .gitignore.

This file is a minified build artifact generated by Vite (confirmed by content hash in filename and minified syntax). The .gitignore file explicitly states that console frontend builds should not be committed:

However, these generated assets are currently committed in src/copaw/console/assets/ (containing 110 minified files and fonts). This violates the stated intent in .gitignore.

Recommended fix: Either:

Browsers parse this CSS in the DOM using standard CSS syntax, which only supports /* ... */ comments. The // tokens are invalid and can interfere with adjacent declarations or selectors.

Example fix
- // .flowchart-label .text-outer-tspan {
- //   text-anchor: middle;
- // }
+ /* .flowchart-label .text-outer-tspan {
+    text-anchor: middle;

- Around line 503-505: The code is chunking already-converted HTML which can
split tags and cause parse errors; instead, perform chunking on the original
markdown/plain text and then convert each chunk to Telegram-safe HTML.
Concretely: replace uses of convert_markdown_to_telegram_html(text) followed by
self._chunk_text(html_text) in the send flow (including the block around
convert_markdown_to_telegram_html and _chunk_text and the similar section at
520-533) with self._chunk_text(text) to get chunks, then loop over those chunks

- Around line 90-101: The parser incorrectly treats trailing text after a
closing ``` as a new code block and can drop inline fenced code because
flush_code_block() is called while in_code_block is toggled incorrectly; update
the logic in the block handling lines with "```" (refer to the in_code_block
flag, flush_code_block(), code_block_content, converted_lines, and escape_html)
so that when closing a fence you do not re-enter code mode for the remainder —
instead assign the remainder back to line for normal text processing (or
continue if empty); and when a single-line fenced code (```code```) is detected
(the branch that inspects after_parts), emit a converted_lines entry (wrapping
escaped content via escape_html into a <pre> or equivalent) rather than
appending to code_block_content and calling flush_code_block(), then continue
processing any trailing text correctly.
- Line 39: The INFO-level logger calls that print user message snippets (the
logger.info(f"[FORMAT] Original: {text[:200]}...") and the similar logger.info
at lines ~307-309) can leak sensitive data; change these to either a
lower-verbosity level (logger.debug) or remove the raw message content entirely
and replace with a non-sensitive placeholder (e.g., logger.debug("[FORMAT]
Original message truncated") or logger.info("[FORMAT] Original message omitted
for privacy")), and ensure you update both occurrences (the logger.info call
that references text[:200] and the later logger.info block around lines 307-309)
so no raw user content is logged at INFO level.
- Around line 61-69: flush_code_block currently only resets state when
code_block_content is non-empty, which can leave in_code_block True for empty
fenced blocks; change flush_code_block so that if in_code_block is True it

block (empty if needed) to converted_lines after escaping via escape_html; keep
the nonlocal declaration and use the same variables (in_code_block,
code_block_content, converted_lines, escape_html) and ensure code_block_content

m.height or the variable representing node height) so the layout uses the
correct height fallback instead of width.

In `@src/copaw/console/assets/xychartDiagram-PRI3JC2R-DpKyYrXD.js`:
- Line 1: transformDataWithoutCategory can loop forever when xMin === xMax
because computed step becomes 0; modify transformDataWithoutCategory to detect
this case and generate distinct x values instead of dividing by zero — e.g., if
(xMax === xMin && data.length > 1) create x positions as xMin + index (or set
step = 1 and adjust start/end accordingly) so the loop that advances by step
will terminate; locate and update the section that computes step/start/end
(references: transformDataWithoutCategory, any local vars named step, start,
xMin/xMax) to short-circuit and produce a deterministic non-zero step or
per-item offsets when all x values are equal.

Minor comments:
In `@src/copaw/console/assets/chunk-B4BG7PRW-TJWoWC1M.js`:
- Around line 112-116: The CSS selector block mistakenly repeats
"#dependencyStart" instead of targeting the dependency end marker; update the
selector so it reads "#dependencyStart, `#dependencyEnd`, .dependency" (or replace
the second "#dependencyStart" with "#dependencyEnd") so both start and end
dependency markers receive the same styles; modify the rule that currently lists
"#dependencyStart, .dependency" to include "#dependencyEnd" alongside
"#dependencyStart" and ".dependency" (referencing the selector names
"#dependencyStart", "#dependencyEnd", and ".dependency").

In `@src/copaw/console/assets/chunk-DI55MBZ5-BMGPkNnz.js`:
- Around line 205-207: The CSS rule for .statediagram .edgeLabel currently
hardcodes color: red which overrides theme-driven colors; replace the hardcoded
value with the theme variable (e.g., use the existing template placeholder
${e.noteTextColor} or a CSS custom property such as var(--note-text-color) with
an appropriate fallback) so edge labels inherit the configured theme color;
update the .statediagram .edgeLabel rule to use the theme variable instead of
"red".

In `@src/copaw/console/assets/diagram-S2PKOQOG-CcEhckg0.js`:
- Line 1: The getNextFittingBlock helper (named H / exported as
"getNextFittingBlock") incorrectly computes split block .bits as r - e.start and
e.end - n which are off-by-one for inclusive start/end ranges; update the two
computed bits to be inclusive (use r - e.start + 1 for the first split and e.end
- n + 1 for the second) so that resulting block.bits match end-start+1 and keep
all other validations (start/end presence and ordering) unchanged.

In `@src/copaw/console/assets/gitGraphDiagram-V2S2FVAM-CsWhjUa7.js`:
- Line 1: The rendering code in function Xr mutates commit state by calling
r.tags.reverse(); change that to iterate over a non-mutating reversed copy such
as (r.tags||[]).slice().reverse() (or [...(r.tags||[])].reverse()) so tag order
isn't altered on re-renders; update the loop that currently uses
r.tags.reverse() to use this copied array.

In `@src/copaw/console/assets/journeyDiagram-XKPGCS4Q-CmA4_6we.js`:
- Around line 98-118: Each .task-type-N and .section-type-N block incorrectly
checks t.fillType0; change the guard in each block to check its matching
property (e.g., for .task-type-1/.section-type-1 use t.fillType1, for
.task-type-2/.section-type-2 use t.fillType2, etc.) so that the template uses
the corresponding t.fillTypeN when generating the fill value for fillType1..7
rather than always gating on t.fillType0.

In `@src/copaw/console/assets/kanban-definition-3W4ZIXB7-SWzUKYw3.js`:
- Around line 12-31: The CSS template is using `.section-${r-1}`,
`.node-icon-${r-1}`, `.section-edge-${r-1}`, and `.edge-depth-${r-1}` selectors
which are off-by-one versus the rendered classes (`section-1`, `section-2`,
...); update those selectors to use `${r}` instead of `${r-1}` so the selectors
in this template match the generated section classes and their colors (adjust
`.section-${r-1}`, `.node-icon-${r-1}`, `.section-edge-${r-1}`,
`.edge-depth-${r-1}` to `.section-${r}`, `.node-icon-${r}`,
`.section-edge-${r}`, `.edge-depth-${r}` while keeping existing uses of
d(t["cScale"+r],10), t["cScaleLabel"+r], t["cScale"+r], t["cScaleInv"+r], and
p).
- Line 1: The type2Str mapping contains a typo returning "hexgon" for the
HEXAGON case; locate the type2Str function (or mapping) in the kanban parser
module (search for type2Str or the HEXAGON branch in the performAction/parse
code) and correct the string from "hexgon" to "hexagon" so class/shape lookups
receive the correct name; update any related unit test or usage that depends on
the exact "hexagon" string to reflect the fix.

In `@src/copaw/console/assets/mindmap-definition-VGOIOE7T-DcDY83n6.js`:
- Line 1: The type2Str() mapping has a typo for nodeType.HEXAGON producing
"hexgon" instead of "hexagon"; update the mapping in the type2Str (or similar
string-mapping) function to return "hexagon" for nodeType.HEXAGON so consumers
receive the correct shape/class name (search for type2Str and nodeType.HEXAGON
in the file to locate and fix the entry).

In `@src/copaw/console/assets/stateDiagram-FKZM4ZOC-WcdK8wPu.js`:
- Line 1: The edge-label loop in the drawEdge function (symbol Q / "drawEdge")
iterates with for (let u=0; u<=o.length; u++) causing an extra undefined entry;
change the loop condition to for (let u=0; u<o.length; u++) (or equivalent
bounds check) so it only iterates actual rows from o = z.getRows(d.title), and
ensure any accesses to o[u] are safe after the change.

In `@src/copaw/console/assets/xychartDiagram-PRI3JC2R-DpKyYrXD.js`:
- Line 1: The left-axis group class name contains a typo "axisl-line" which
should be "axis-line" so shared selectors/hooks work; search the diff for the
string "axisl-line" and replace it with "axis-line" wherever it appears (e.g.,
in any DOM creation/selection or class assignment in the minified module that
defines axis groups such as the chart/axis rendering code and
performAction-related strings) ensuring consistency with other axis group names.

Duplicate comments:
In `@src/copaw/app/channels/telegram/format_converter.py`:
- Around line 56-57: The f-string embeds a backslash-escaped string expression
("'\n'.join(blockquote_lines)") which is invalid on Python <3.12; change it so
the join is computed outside the f-string (e.g. assign joined =
"\n".join(blockquote_lines)) and then interpolate joined into the f-string or
use string concatenation, updating the expression that references
blockquote_lines in format_converter.py (the line producing "<blockquote>...")
to avoid escapes inside the { } expression.

In `@src/copaw/console/assets/c4Diagram-YG6GDRKO-8lrJiWgp.js`:
- Line 1: Remove the stray undeclared identifier from the lexer by locating the
switch case labeled "case 14" inside the generated lexer/switch in the parser
(the lexer used as D or the D.lex switch in the parse function) and delete the
bare "c" so the case becomes a no-op (e.g., just break); ensure it reads "case
14: break;" (or equivalent no-op) to avoid ReferenceError when that lexer path
is hit.

In `@src/copaw/console/assets/chunk-DI55MBZ5-BMGPkNnz.js`:
- Line 1: The code currently writes m.url (from the click stmt created in
performAction cases 32/33) directly into xlink:href after only trimming quotes;
locate the code that sets xlink:href for clickable SVG nodes (referencing m.url
or the click stmt produced in performAction case 32/33) and replace the direct
assignment with a sanitized URL: parse and trim the value, validate its scheme
against a whitelist (e.g., http, https, mailto, tel, ftp), reject or neutralize
unsafe schemes like javascript: and data:, and only assign the sanitized/allowed
URL to xlink:href (or omit the attribute if invalid). Ensure you centralize this
in the renderer/helper that binds click stmts to SVG nodes so all uses of the
click stmt (created in performAction case 32/33) are covered.

Nitpick comments:
In `@src/copaw/app/channels/telegram/channel.py`:
- Around line 161-166: Replace the manual "file://"+local_path concatenation
with a robust Path-based URI construction: when building file_url from
local_path (the variable used in the channel Telegram code), check if local_path
already starts with "file://" and otherwise convert via
pathlib.Path(local_path).resolve().as_uri(); update both occurrences (the block
creating file_url and the similar logic at the later occurrence) and add the
necessary pathlib import (Path) if missing to ensure cross-platform escaping and
normalization.

In `@src/copaw/console/assets/chunk-4BX2VUAB-BEvcyVQL.js`:
- Line 1: The checks in function m currently use truthy checks on e.accDescr,
e.accTitle, and e.title which skip empty-string updates; change them to explicit
presence checks (e.g., use "accDescr" in e or
Object.prototype.hasOwnProperty.call(e, "accDescr") / check for undefined)
before calling c.setAccDescription, c.setAccTitle, and c.setDiagramTitle so
callers can clear values with empty strings; update the logic for all three
fields in function m and then regenerate the bundled asset
(chunk-4BX2VUAB-BEvcyVQL.js).

In `@src/copaw/console/assets/chunk-DI55MBZ5-BMGPkNnz.js`:
- Around line 183-196: Remove the duplicated CSS rule for the selector
.statediagram-note rect: locate both identical blocks labeled
".statediagram-note rect" and delete one of them so only a single declaration
block (using e.noteBkgColor and e.noteBorderColor, stroke-width, rx, ry)
remains, preserving the remaining instance exactly as-is.

In `@src/copaw/console/assets/chunk-TZMSLE5B-DB6V8Dki.js`:
- Line 1: In drawRect (the function exported as x / "drawRect") replace the
truthy checks for t.rx and t.ry so they don't skip valid zero values: instead of
"t.rx && e.attr('rx', t.rx)" and "t.ry && e.attr('ry', t.ry)" use explicit
undefined checks (e.g., check t.rx !== undefined and t.ry !== undefined) before
calling e.attr, ensuring 0 is preserved; keep the rest of the attribute logic
(including the t.attrs loop and t.name/class handling) unchanged.

In `@src/copaw/console/assets/ganttDiagram-JELNMOA3-aggv0wze.js`:
- Around line 1-267: This PR includes a committed minified bundle (the module
that exports "Is as diagram" and defines symbols like parser Ni, db bs, renderer
Ds, styles Ss and functions wn/Cs/Ms), which should be removed from source
control; instead remove this file from the PR, restore/modify the original
source modules, and update the build/CI pipeline to produce the minified asset
during CI or release steps. Also add/adjust gitignore and any repository
policies to prevent committing generated bundles, and re-submit the PR with only
source-module changes (or with the bundle generated by CI) so reviewers can
inspect real source (e.g., update build scripts that produce the module
referenced by wn, Cs, Ms and the exported Is).

In `@src/copaw/console/assets/gitGraphDiagram-V2S2FVAM-CsWhjUa7.js`:
- Line 1: In setParallelBTPos (function Dr) you must validate that each parent
id resolves before calling Ur; wherever Ur(a, r.get(n), e, r) is invoked, check
r.has(n) (or that r.get(n) is truthy) and throw a clear Error like `Parent not
found for commit ${a.id}: ${n}` if missing, so the code fails fast with
contextual information instead of throwing deeper/unclear errors.

In `@src/copaw/console/assets/index-w_uOUyFM.css`:
- Line 1: The CSS contains duplicate rules for the
.index-module__envRowSelected__VaIjO selector (and its :hover variant) — locate
both occurrences of .index-module__envRowSelected__VaIjO and remove the
redundant block so only a single declaration remains (if the two blocks differ,
merge the unique properties into one consolidated
.index-module__envRowSelected__VaIjO { ... } and
.index-module__envRowSelected__VaIjO:hover { ... } pair to preserve behavior).
Ensure no other selectors (e.g., .index-module__envRowSelected__VaIjO:hover) are
left duplicated after the cleanup.

87-98: ⚠️ Potential issue | 🟠 Major

Fix fence transition logic for trailing text and inline fenced code.

Line 97 re-enters code mode for trailing text after a closing fence, and Lines 149-151 can drop ```code``` content because flush_code_block() is called while not in code mode.

Proposed fix

60-68: ⚠️ Potential issue | 🟠 Major

Fenced-code parsing still has state bugs for empty/inline/trailing fence cases.

Empty fenced blocks can leave parser state inconsistent, trailing text after a closing fence is misclassified, and inline ```code``` still routes through a path that can drop content.

Security fix: Links in Markdown are now properly HTML-escaped before
embedding in <a> tags. This prevents potential XSS attacks and HTML
parsing issues when link text or URLs contain special characters.

Changes:
- Updated escape_html() to support optional quote escaping
- Modified all 3 link replacement locations to use callable functions
- Link text is escaped with escape_html(text)
- Link href is escaped with escape_html(href, quote=True)

Fixes review finding about raw regex captures in HTML output.
Removed files that were incorrectly placed under src/copaw/console/:
- index.html (correct location: console/index.html)
- copaw-symbol.svg (correct location: console/public/copaw-symbol.svg)
- logo.png (correct location: console/public/logo.png)

Updated .gitignore to ignore entire src/copaw/console/ directory
as it should not contain any source files.
Ignore console/assets/ and console/dist/ (build artifacts)

Restored from upstream/main:
- console/index.html
- console/public/copaw-symbol.svg
- console/public/logo.png
1. Security: Mask sensitive content in logs
   - Change logger.info to logger.debug
   - Add mask_text() helper to sanitize text before logging
   - Apply to both input and output log statements

2. Robustness: Fix code block fence handling
   - flush_code_block() now always resets state (even for empty blocks)
   - Closing fence properly handles trailing content without re-entering code block
   - Single-line code blocks (\`\`\`code\`\`\`) are processed directly without state changes
   - Prevents edge cases with inline/trailing/empty fences

Problem: Converting entire message to HTML before chunking can split
HTML tags across chunk boundaries, causing Telegram parse errors.

Solution:
1. Chunk the original markdown text first (at 4096 char boundaries)
2. Convert each chunk individually to HTML
3. Send each converted HTML chunk separately

This ensures HTML tags are never split across message boundaries.

Fallback: If HTML parsing fails for a chunk, send as plain text.

Pull request overview

Adds Telegram message formatting support by converting Markdown responses into Telegram-compatible HTML, and extends Telegram sending to support topic threads and improved local media URL handling.

Changes:

  • Added a Markdown → Telegram HTML converter with basic support for headings, emphasis, code blocks, blockquotes, tables, lists, separators, and links.
  • Updated Telegram channel sending to convert outgoing text to HTML (parse_mode="HTML"), add message_thread_id support, and refactor media sending.
  • Updated tests and release/docs metadata (command set test, README bullets, version string, package-lock cleanup).

send_media_payload always sets parse_mode="Markdown", but these send* calls don’t include a caption parameter, so parse_mode is effectively unused (and the PR description mentions “media captions”). Either remove parse_mode here for clarity, or plumb a caption field through OutgoingContentPart/meta and apply consistent formatting (likely HTML) when a caption is actually sent.

_start_typing() no longer cancels any existing typing task for the same chat_id. If multiple messages arrive before a reply is sent, this will leak the previous asyncio.Task(s) and cause multiple concurrent typing loops to run until timeout (and the old task can’t remove itself from _typing_tasks because the dict entry has been overwritten). Consider calling _stop_typing(chat_id) before creating a new task (as before), or otherwise ensuring only one typing loop per chat_id can exist at a time.

send() chunks the raw Markdown and then runs the Markdown→HTML converter on each chunk independently. This can break multi-line constructs (e.g., fenced code blocks or blockquotes) that span chunk boundaries; the converter will treat an opening fence/quote in one chunk as “unterminated” and flush it at the end of that chunk, producing incorrect HTML (and potentially triggering Telegram parse errors). Consider converting the full message first and then chunking the resulting HTML with an HTML-aware chunker, or making the chunker/converter stateful across chunks so fences can span multiple chunks safely.

convert_markdown_to_telegram_html builds Telegram “HTML” output but most transformations insert user-controlled text directly into HTML tags without escaping (e.g., , , , , headings). If the input contains characters like <, >, &, or quotes, Telegram parsing can fail or unintended formatting/HTML injection can occur. Please ensure all non-tag content is HTML-escaped before being embedded into tags (similar to what you already do for code blocks and link text/hrefs), ideally by using re.sub replacement functions that call escape_html() on captured groups.

Table header bolding is skipped when the previous converted row starts with "<". This means headers that start with a formatting tag (e.g., a link "Col" → "<a …>") won’t be bolded even though the converter advertises automatic header bolding. Consider bolding per-cell (split on tabs and wrap cells that aren’t already bold) rather than using a startswith("<") guard on the whole row.

# Support single-column tables (no tabs)

cells = prev.split("\t")
converted_lines[-1] = "\t".join(
f"<b>{cell}</b>" for cell in cells

# Single column case

# Support both single-column and tab-separated tables.

The debug logs use f-strings (mask_text(...)) inside logger.debug(), which eagerly formats even when debug logging is disabled. Prefer logger.debug("[FORMAT] Input: %s", mask_text(...)) (or guard with logger.isEnabledFor(logging.DEBUG)) to avoid unnecessary work on every conversion.

Hi! @hh0592821 Thank you for all the work you’ve put into this. We’ve been closely tracking this issue.

Shortly after you opened this PR, PR #850 was submitted targeting the same bug. After running local tests, we’ve decided to proceed with #850 for the merge.

The main reason is correctness: we later found a case where #717 can still fail to parse when the output contains raw angle brackets (< / >). In #717, some fallback paths can append raw text without a full escape, so messages with plain <> may still break parsing. #850’s placeholder-based, multi-phase pipeline escapes the full text before formatting, which makes it more robust for these cases.

That said, we really appreciate your contribution here. Your PR also includes several useful improvements (e.g., broader Telegram send handling) that are valuable, and we’d love to work with you to bring those pieces in.

If you have ideas or want to iterate on a follow-up PR, please keep the discussion going. We’re happy to collaborate.

Understood, thank you for your response. I will close this PR and reorganize it to include other enhanced features for Telegram message sending.
