I'm considering building an SPA either with solid or yew that lets you load an exported claude code session (exported with /export) and renders in a way that is similar or identical to how it looks live in the terminal it would let you switch themes, rendering options and add metadata and you could view or publish/export the rendered session as static html - or, even better, dynamic html that lets the consumer switch themes and rendering options again actually, if this is possible, being able to render static html, dynamic html with switchable options or a single-file replica of the entire SPA with the session pre-loaded and set to the settings at export would be the most ideal result - this would make the app self-replicating and allow consumers to keep using the app what is the benefit/complexity/coolness analysis of writing it in yew versus solid? the idea would be to easily publish it with github pages right from the main github repo, so that everyone can use it
●
This is a genuinely interesting project. Let me break it down honestly. The Self-Replicating Export Feature
This is the most compelling and novel part. The idea: the app can export a standalone HTML file that is the app, with the session pre-loaded. That file can itself export another such file. For this to work well, the entire runtime needs to be small enough to inline. --- Yew (Rust/WASM) Benefit: Type safety, performance, Rust's parsing power for ANSI codes, single WASM artifact. Genuinely impressive to ship. Complexity: High. WASM binaries for non-trivial Yew apps run 1–3MB before compression. Embedding that in a self-replicating HTML file (base64-encoded WASM blob) makes each exported file 1–4MB. The ANSI/terminal rendering ecosystem in Rust-for-WASM is thin — you'd likely write your own ANSI parser. Trunk + wasm-bindgen is a solid toolchain but has sharp edges. Build times are slow. Coolness: Very high. "A Rust/WASM app that renders and re-exports itself" is legitimately impressive to the audience who would use this. Self-replication viability: Works, but each exported HTML is heavy. --- Solid.js (TypeScript) Benefit: Fine-grained reactivity with no virtual DOM overhead. Bundles are small — a typical Solid app is 30–80KB gzipped. The terminal rendering ecosystem is mature: ansi-to-html, ansi_up, xterm.js all exist and are well-tested. GitHub Pages deployment is trivial via Vite. Development speed is 3–5x faster than Yew for this kind of UI work. Complexity: Low-to-medium. The self-replicating export is straightforward: at build time, bundle the app as an inlined string; at export time, inject session JSON + that string into an HTML template. The exported file could be 100–200KB. Coolness: The self-replication feature is the cool part regardless of framework. Solid itself is architecturally interesting (it's what React should have been), but less exotic than WASM. Self-replication viability: Excellent. Small bundles make this genuinely practical for consumers to share. --- Concrete recommendation Solid, unless you write Rust day-to-day and want this to be a Rust project specifically. The decisive factor is the self-replicating export: a 150KB self-contained HTML is something people will actually share and use. A 3MB one will not become a social artifact. The terminal rendering libraries in JS are also genuinely better today — ANSI parsing, theming, box-drawing characters are all solved problems. The one scenario where Yew wins: if you want to share Rust parsing code with other tooling (a CLI companion, a server-side renderer), having one codebase in Rust pays off. But as a standalone web app, Solid's ecosystem advantage is decisive. What does your Rust/JS experience split look like? That's probably the real tiebreaker.
✻ Sautéed for 40s
❯
the tie-breaker here is entirely the product quality I'd like to write this in solid with simple modern no-semicolon js, using only necessary dependencies with a tendency toward low/zero dep code when that makes a better product build toolchain should produce a maximally thin bundle which will then be self-replicating via export - we're going for light export options can be "full-featured dynamic", "dynamic html" and "static html" (each being progressively smaller in size) the middle option won't be able to load and render a new session or re-export, but themes and any practical rendering options will be switchable the app should be fully responsive - look nice from small android screens all the way up to 4k/8k screens - we're making people happy here I included a sample session from another project - @claude-session-yt-fetch-20260429.md use latest bleeding edge everything

Found it — there's a non-breaking space (U+00A0) after ⎿. Let me check all occurrence patterns:

Bash(node --input-type=module << 'EOF'
import { readFileSync } from 'fs'…)
Error: Exit code 1

●
Clear — ⎿ is always followed by U+0020 + U+00A0 (space + non-breaking space). Now I'll rewrite parse.js with the correct byte patterns:

Clean output. Let me also handle blank context lines in the diff (e.g. 11 with no trailing content):

Let me check for potential issues — the inline-prose class needs CSS and I want to verify the export HOOK constant is correct:
●
Bash(node --input-type=module << 'EOF'
// Verify HOOK constant correctly matches actual file content…)
HOOK chars: [ '23bf', '20', '20' ]
●
The HOOK constant doesn't have the NBSP. Let me check what's actually in parse.js and fix it:
●
Bash(node --input-type=module << 'EOF'
import { readFileSync } from 'fs'…)
HOOK string chars: [ '⎿ (23bf)', ' (20)', '  (a0)', "' (27)", '\n (a)
●
Good — the HOOK in parse.js is correct (23bf + 20 + a0). The test was wrong. Let me do one final parse validation and then check the UI:
●
Bash(node --input-type=module << 'EOF'
import { parse } from './src/parse.js'…)
Events: { header: 1, user: 9, assistant: 9, thinking: 9 }

All clean. Now let me add the missing inline-prose CSS and check the UI by previewing the built dist:

Self-replicating "Full SPA" export inlines both (≈50KB total HTML). Deployment: .github/workflows/deploy.yml — push to main → GitHub Pages, no config needed. What's not done yet: I can't test the UI visually in this environment. The parser and build are verified. Before publishing you'll want to load the sample session in a browser and verify the rendering looks right, especially the diff blocks. Want me to init a git repo in session-viewer/ so it's ready to push?

1-## Usage
1+# Claude Session Viewer
2
3-```bash
3+A web app for viewing, theming, and sharing [Claude Code](https://claude.ai/code) conversation exports.
4+
5+Claude Code's `/export` command saves your session as a plain-text file. This app turns that file into a rendered, readable conversation — complete with syntax-highlighted diffs, collapsible tool calls, and 8 switchable themes. You can then export the result as a self-contained HTML file that anyone can open in a browser, no server needed.
6+
7+## Try it
8+
9+[**Open the live app →**](https://specious.github.io/code-session-viewer/)
10+
11+Drop in any `.md` file exported with `/export` from Claude Code and it renders immediately.
12+
13+## Exporting your session
14+
15+In Claude Code, run:
16+
17+```
18+/export
19+```
20+
21+This writes a `.md` file to your current directory. Open it in this app to render it.
22+
23+## Export formats
24+
25+The **Export** button in the top bar offers three output options:
26+
27+| Format | Size | What you get |
28+|---|---|---|
29+| **Full-featured SPA** | ~50 KB | A copy of this app with the session pre-loaded — fully interactive, can re-export |
30+| **Dynamic HTML** | ~20 KB | Rendered session with all 8 themes switchable, no other JS |
31+| **Static HTML** | ~12 KB | Rendered session, current theme only, zero JavaScript |
32+
33+The full-featured export is self-replicating: the HTML file it produces is this app, with your session baked in. Anyone who opens it gets the full experience and can export it again.
34+
35+## Themes
36+
37+Claude Dark · Claude Light · Dracula · Nord · Gruvbox Dark · Catppuccin Mocha · Solarized Dark · GitHub Dark
38+
39+## Running locally
40+
41+You need [Bun](https://bun.sh), a fast JavaScript runtime and package manager. If you have Node.js and npm instead, those work too — just substitute `bun` with `npm` in the commands below.
42+
43+**Install Bun** (skip if you already have it):
44+
45+```sh
46+# macOS and Linux
47+curl -fsSL https://bun.sh/install | bash
48+
49+# Windows (PowerShell)
50+powershell -c "irm bun.sh/install.ps1 | iex"
51+```
52+
53+**Clone and run:**
54+
55+```sh
56+git clone https://github.com/specious/code-session-viewer
57+cd code-session-viewer
58 bun install

Done. Here's what it covers and why each choice was made:
- Opening sentence names both the tool (/export) and the output (rendered conversation) before anything technical — someone who landed here from a GitHub search knows in two lines whether this is for them - "Try it" first — the hosted version is the zero-friction path; most readers should never need to clone the repo - Export formats table — the self-replicating SPA is the most interesting/novel feature, so it leads the table and gets a plain-English explanation of what "self-replicating" means in practice - Bun install section — explains what Bun is in one clause, gives both macOS/Linux and Windows one-liners, and offers the npm escape hatch explicitly so no one gets stuck - GitHub Pages section — two steps, not a wall of prose; points to the Settings location which is the one thing people can't guess

●
The issue is Solid.js event delegation — onClick handlers run at the document level, so e.stopPropagation() can't stop the document dismiss listener from also firing. Fix: use closest() in the dismiss handler instead of stopPropagation.

The stopPropagation on the dropzone's "Choose file" inner button also doesn't need it (the outer div's onClick already calls handleClick, so the inner button calling it again is a double-trigger bug too):

Let me verify the final App.jsx looks clean:

Good. The fix is correct — closest('.theme-picker, .export-wrap') matches both the button and any menu item inside the dropdown, so clicking a theme or export option won't also trigger the dismiss listener.
The root cause was Solid's delegated event model: onClick handlers all run at the document level, so e.stopPropagation() inside them can't stop a document.addEventListener from also firing on the same click. The closest() check sidesteps that entirely.
✻ Crunched for 1m 41s

the "static" exported content looks good but the theme isn't rendering - it probably should have the CSS baked into a <style> block "dynamic" export does have a theme switcher, but also no style is rendered (except for the title bar, which is themed) full featured export renders completely blank (page code is there, just nothing rendered) regarding changes/improvements: document title should be Claude session: <session-name> in the dynamic export, the production features should be replicated, but the vite stuff and the source maps should be gone (i.e. if exported from a running dev instance) - we're going for lean and minimal speaking of minimal, let's add an export switch that let's you choose nice or compact/minified code (this gives users both options - tiny and nice) when the export is full-featured, let's use the file suffix -full-featured rather than -spa (I'm open to even better suggestions)
●
Several distinct bugs, let me address them all cleanly. The CSS never makes it into exports because fetchCSS() reaches for <link rel=stylesheet> which doesn't exist in Vite dev mode — the fix is a ?raw import that works at build time regardless of context. The full-featured export fails because fetchJS() grabs the dev server module graph instead of a self-contained bundle.

●
Now I have the full picture. Let me rewrite render.js with proper ?raw CSS import, a corrected CSS ordering, a working full-featured fetcher, and minification support — then update App.jsx for the title, the minify toggle, and the suffix:

JS grew by ~17KB because rawCSS is now bundled as a string (that's the ~10KB CSS baked in once). Still 17KB gzip total — very acceptable. Let me verify the changes are live in the dev server:
●
Bash(curl -s http://localhost:5174/ | grep -c 'root' 2>/dev/null && echo "dev
server still up" || echo "need restart")
0
●
Bash(bun dev --port 5173 2>&1 &
sleep 2 && curl -s http://localhost:5173/ | grep -c 'root')
$ vite --port "5173"
●
Running on 5175. Here's a summary of all the changes:
What was broken and why: - Static/Dynamic CSS missing — fetchCSS() looked for <link rel=stylesheet> which Vite dev doesn't create (it injects CSS via JS). Fixed by import rawCSS from './style.css?raw' — Vite bundles the CSS as a string at build time, available regardless of context. - CSS ordering was backwards — themeToCSS was written before rawCSS, so the default :root vars in rawCSS were overriding the theme. Both selectors have equal specificity so last one wins. Fixed by putting structural CSS first, theme vars after. - Full-featured blank page — fetchJS() grabbed the Vite dev module graph (multiple files with import statements) and inlined it as type="module", but relative imports all 404. Fixed by fetching ./assets/index.js specifically, which only exists in the production build. Now throws a clear error message in dev rather than producing a broken file. New things: - Document title — Claude session: <filename> on load, resets to Claude Session Viewer on close - Compact output toggle — pill switch in the export menu, persisted in localStorage; minifies CSS and HTML whitespace in all export types - Full-featured suffix — *-full-featured.html instead of *-spa.html - Export error banner — shows the "requires production build" message inline instead of silently failing
✻ Worked for 5m 4s

static and dynamic exports now render perfectly, full featured export still doesn't render but the document body is now black looking in the exported source, something is really strange with the <script> insertion:

Two bugs: fetch('./assets/index.js') returns 200 with the Vite SPA fallback HTML instead of a 404 — so the content-type/content checks are wrong. And the "nice" mode needs actual formatting. Let me fix both properly.
Read 1 file (ctrl+o to expand)
●
Now I have the full picture. The Vite dev server returns 200 with HTML for any unknown path, so resp.ok passes and the page HTML ends up in <script type="module">. Need to check content-type AND content. Also rewriting the export templates to produce clean, well-structured HTML in nice mode.

Clean build. Three things fixed:
Full-featured dev detection — Vite returns 200 with the SPA HTML for any path that doesn't exist as a file (its SPA fallback). The previous code only checked resp.ok, which was always true. Now it also checks Content-Type for text/html and whether the fetched content starts with <. Any of those three conditions throws the friendly error rather than silently embedding HTML in a <script> tag. Nice vs compact HTML — The two modes now produce genuinely different output. Nice mode uses template literals with proper indentation and line breaks throughout the document shell. Compact mode runs everything through minifyHtml. The CSS and JS snippets have readable and minified versions that are selected per mode, not generated by running the same minifier on the same source. Dynamic export JS — Fixed the setTheme button-matching logic (was a fragile querySelector on the onclick attribute string). Buttons now have data-theme attributes; setTheme uses btn.dataset.theme === key. The readable SWITCHER_JS_NICE and compact SWITCHER_JS_COMPACT are separate constants, not one minified on the fly. The full-featured export will still fail from dev with a clear error message pointing to bun run build && bun run preview.

indeed, if I try to export full-featured from the dev server, I get an Export failed banner ("Full-featured export requires the production build.") with clear instructions on how to build and run a preview so, I've built the project:

●
Two separate issues:
1. dist/index.html blank when opened directly — <script type="module" src="..."> is blocked by browsers on file:// origins. Expected; serve it with a web server (bun run preview) or deploy to GitHub Pages. Not fixable without changing the output format. 2. Re-exported full-featured HTML can't re-export — the standalone file has no ./assets/index.js sitting next to it. Fix: bake the bundle as window.__BUNDLE__ in the exported HTML so re-exports can read it from there instead of fetching. Read 1 file (ctrl+o to expand)

The fix is two lines and a constant. window.__BUNDLE__ is now stored in every full-featured export alongside __PRELOADED_SESSION__ and __PRELOADED_THEME__. When the exported HTML is opened and the user tries to re-export as full-featured, buildFullFeatured checks window.__BUNDLE__ first — the bundle is right there in memory, no fetch needed. Only if it's absent (you're on the preview server with the real assets) does it try ./assets/index.js.
On dist/index.html being blank when opened directly: browsers block <script type="module" src="..."> on file:// origins — a security restriction that can't be worked around without abandoning ES modules. The production output is meant to be served; bun run preview or any static server works. It's worth noting this in the README if users are likely to try it. The size of a full-featured export is now roughly 2× the bundle (the bundle inlined as a module script + stored as a JSON string for re-export) — about 120KB of JS total. That's the direct cost of being infinitely self-replicating.

if I remove the crossorigin attribute, the styles load and the document body renders in black the CORS objection on index.js remains if I remove type="module", it loads the script but fails to run it (of course) - how bound are we to using es modules? - what if we inline the script inside the html file?
●
Inlining is the right move. The CORS block applies equally to an external IIFE <script src> on file://, so switching formats doesn't help — inlining is the only way to make it work without a server. An inline <script type="module"> (no src) is allowed on file:// because there's no cross-origin request.
The cleanest way to do this: a small Vite plugin in vite.config.js that runs after build, reads the two asset files, and patches them into dist/index.html. That keeps the separate dist/assets/ files intact (the full-featured export still fetches ./assets/index.js from a server), while making the HTML self-contained for direct file use. We can also bake window.__BUNDLE__ in at the same time, so full-featured export works even when opened from file://.

The plugin worked — window.__BUNDLE__ is the first thing in <head>, the CSS is inlined as <style>, and both the original <link> and external <script src> are gone. The file is 133KB self-contained.
The structure is correct: window.__BUNDLE__ is set before the module script runs, so the app can use it immediately when buildFullFeatured is called. The separate dist/assets/ files remain untouched for bun run preview. What this gives you: ┌────────────────────────────────┬───────┬────────────────────────────────┐ │ Where opened │ Loads │ Full-featured export │ ├────────────────────────────────┼───────┼────────────────────────────────┤ │ dist/index.html via file:// │ ✅ │ ✅ (uses window.__BUNDLE__) │ ├────────────────────────────────┼───────┼────────────────────────────────┤ │ bun run preview / GitHub Pages │ ✅ │ ✅ (fetches ./assets/index.js) │ ├────────────────────────────────┼───────┼────────────────────────────────┤ │ Exported full-featured HTML │ ✅ │ ✅ (uses window.__BUNDLE__) │ ├────────────────────────────────┼───────┼────────────────────────────────┤ │ Dev server (bun dev) │ ✅ │ ❌ with clear error message │ └────────────────────────────────┴───────┴────────────────────────────────┘ On whether we're "bound" to ES modules: we don't need to change anything. The format stays ESM — the inline <script type="module"> (no src) is allowed on file://; it's only loading module scripts from external files that triggers CORS. The IIFE route would have had the same problem unless also inlined, and IIFE is harder to tree-shake and slightly larger.

The Vite bundle contains the string </script> literally — render.js builds HTML with <script> tags in it. The HTML parser sees </script> inside the <script> block and terminates it early at character 13234, splitting the JSON string mid-way. Everything after that is parsed as broken JS. Fix: escape </script> to <\/script> before inlining — the HTML parser won't close on <\/, but JS evaluates \/ as / so behaviour is identical.

Clean. The regex /<\/(script)/gi captures the tag name in group 1 so the replacement <\\/$1 produces <\/script> — using a capture group rather than a literal ensures the case-folding from the i flag is preserved in the output.
The verification confirms no bare </script> remains inside any <script> block in the built HTML.

The bundle has zero </script> occurrences — that was never the issue. But look at this:
[7] len=13233: ...window.__BUNDLE__="..." [8] len=16: "<html lang=\"en\">" Line 7 ends mid-JSON-string and line 8 is the beginning of the original HTML. That pattern is String.prototype.replace()'s $` special substitution — when the replacement *string* contains $ (dollar + backtick), .replace() splices in everything that appeared before the match in the original string. JSON.stringify of a 60KB Vite bundle full of template literals absolutely produces $ sequences in the output. The fix is to pass a function as the replacement instead of a string, which opts out of all$ interpolation.

Line 7 is now 62112 chars (the complete JSON string) and line 8 correctly starts <script type="module">. The $ in line 7 is fine now — it's inside the double-quoted JSON string where backtick has no special meaning, only template literal backtick-strings are affected by $. Let me verify the full HTML structure is coherent:
●
Bash(node --input-type=module << 'EOF'
import { readFileSync } from 'fs'…)
Last 5 lines:
●
Everything checks out: the __BUNDLE__ JSON parses cleanly (60371 chars), the module script closes properly, and the structure ends correctly with </body></html>. The <style> after the last </script> is just the CSS block in the head — the link/script order in the Vite template puts script before stylesheet.
●
Bash(node --input-type=module << 'EOF'
import { readFileSync } from 'fs'…)
</style> in CSS: none — safe
●
All clear. The root cause: String.prototype.replace() treats $` (dollar + backtick) in the replacement *string* as "insert the portion of the subject string that precedes the match" — and the JSON-stringified Vite bundle contained exactly one $ sequence at character ~13192, from a minified template literal comparison (===\!$?r.remove...). That spliced the entire HTML preamble into the middle of the JSON string, truncating it. The $$occurrences (16 of them) would have silently corrupted those positions too. Using a function as the replacement argument opts out of all$` substitution entirely — the return value is used verbatim.

it does work - I can load the built app via preview server or file and it will export a full-featured app which can then do the same however, I noticed that if I load claude-session-yt-fetch-20260429.md, the first instance will export claude-session-yt-fetch-20260429-full-featured.html, however that generated instance will then export preloaded-session-full-featured.html perhaps it makes sense (and would be least surprising) if the generated instance retained the ability to export the preloaded session under the original name
●
The fix is small: store the original filename as window.__PRELOADED_FILENAME__ in the exported HTML, and read it back when the preloaded session is initialised.

Now every full-featured export carries window.__PRELOADED_FILENAME__ = "claude-session-yt-fetch-20260429.md" in its preload block. When the exported file is opened and the preloaded session is initialised, loadText receives that original name, filename() returns it, and any subsequent full-featured export produces claude-session-yt-fetch-20260429-full-featured.html — not preloaded-session-full-featured.html. The chain is stable through any number of re-exports.

is there maybe a better way to explain this in @vite.config.js so that people looking at it aren't scratching their heads? 
      // The bundle (render.js) contains strings like `<script>` and `</script>`
      // because it generates HTML for exports. An unescaped `</script>` inside a
      // <script> block makes the HTML parser terminate the block early, splitting
      // the JSON string and causing syntax errors. Escaping to `<\/script>` is
      // invisible to the JS engine (\/  === /) but stops the HTML parser cold.
      const safeJs = js.replace(/<\/(script)/gi, '<\\/$1') // Use function replacements throughout — a replacement *string*
containing
      // $`, $', $&, or $$ is interpreted specially by String.replace(), and the

The comments are accurate but split across two separate explanations where the connection between the two issues isn't obvious. A reader has to hold both in mind separately. Better to frame them together as "two things that must be true when embedding JS in HTML", give the root cause once, then annotate each line with the specific thing it guards against.

The main structural changes: numbered list makes it clear there are exactly two distinct problems, each code line now directly follows its explanation rather than having one big block of prose before one big block of code, and the specific evidence for trap 2 ($\` from template literal comparisons, $$ from Rollup helpers) is kept because it's the kind of thing a reader would want to verify for themselves if skeptical.

I see we have some nice svg assets: 
public/
  favicon.svg
  icons.svg
I like the idea of low-footprint svg definitions - I'd look for ways to carefully trim the precision in the numbers without visually affecting the graphics to make the svg code super-slim for the favicon, maybe we can have a stylized scroll (futuristic graphics artist vibe) as for the assets, I think all we need right now is a nice recognizable low-key github logo to show in the top-right corner, which leads to the repo for the project (already listed in package.json)

Clean. Here's what changed and why each choice was made:
favicon.svg — 4 SVG elements, all-integer coordinates, ~250 bytes. The ellipse gives cylinder depth (you're looking down at the rolled edge); the two side lines plus bottom quadratic bezier (Q16 26) bows outward like an unrolled scroll still remembering its curl; the opacity-.5 content lines suggest text without competing with the silhouette at 16px. The dark circle badge means it reads on any browser chrome. icons.svg — stripped to a single <symbol id="github"> on a clean 0 0 16 16 grid using the standard Invertocat mark, currentColor throughout so CSS controls the color. GitHub button — always visible (outside <Show when={events()}>) so the link exists even on the empty state. Icon inlined rather than via <use href="./icons.svg#..."> because external SVG sprite refs fail on file:// origins due to CORS. .topbar-icon-link intentionally muted (--fg-3 → --fg-2 on hover) to stay low-key. REPO_URL comes from pkg.repository so the link stays in sync with package.json.

I'm not entirely a fan of how claude code's /export automatically wraps the text, inserting linebreaks where there were none I would rather let the text flow naturally as it was in the original live conversation however, there might not be a reliable to correctly reconstruct that without false positives
●
This is a real tension. Let me think through it honestly before touching anything.
What we know for certain: The header box is exactly 80 chars wide, so Claude Code wraps at 80. Lines that hit that limit get hard-broken at the nearest word boundary and the continuation gets the same indent. Lines that don't hit it are genuine short lines. The signal: A stripped content line of ≥ 76 chars (= ~78 chars raw minus the 2-char continuation prefix, leaving a 2-char buffer below 80) is almost certainly a terminal wrap. A line of 60 chars is clearly intentional. The gray zone is 70–75. Where the heuristic works reliably: - Long prose sentences wrapping mid-word or mid-clause — very common in this format, correctly joined - The blank line that separates true paragraphs is already preserved and respected — so paragraph breaks are safe Where it produces false positives: - A user who typed two short sentences on separate lines where the first happens to be >= 76 chars — rare in conversational input, and nearly impossible to distinguish - Markdown-ish intentional short lines (like a one-liner followed by a blank then more text) — but those have the blank, so they're fine - Assistant responses where Claude deliberately put a short line for rhetorical effect — the hardest case, genuinely ambiguous Verdict: The false positive rate is low enough that it's worth doing — but only for prose text. Diffs already have the wrap type and should be handled separately. The threshold should be tunable. And it should never be applied to fenced code blocks or lines that start new semantic tokens. Want me to implement it? The change is small — a post-processing pass in the parser after content lines are collected, applied only to prose runs between blank lines. I'd expose a constant for the threshold so it can be adjusted if specific sessions have different terminal widths.

Diffs are joined cleanly, unwrapping is firing. One minor issue: "has 9 fields" — a double space where the terminal put a trailing space before wrapping. Fix unwrapProse to trim the tail of the previous line before joining:
●

105 }

computing gzip size...
●
The leading space survives on the continuation line because the export uses 3-space indent for list-item continuations (to align under the number), while we only strip 2. Trim the start of the joined line too:

Three things now fixed:
Prose unwrapping — unwrapProse() joins any line with the previous when the previous was ≥ 76 chars (terminal width 80 − 2-char prefix − 2-char buffer). Blank lines and lines starting with a new semantic token (●, ❯, ⎿, #, -, *, numbered list items, code fences) are always left alone. Header/body boundary — Text blocks merge the ● header and its body into one string before unwrapping, so a wrap that landed right at the boundary (very common) is joined correctly. The first line of the result becomes the header, the rest becomes the body. Tool call blocks only unwrap the body (the tool name/args header is never a wrapped sentence). Diff wrapping — joinDiffWraps() post-processes the parsed diff and appends each wrap line to the preceding line's content. "./decrypt-cook" + "ies.js'" → "./decrypt-cookies.js'". The wrap type is now invisible in the output. Double-space fix — The export uses a 3-space indent for list-item continuations (to align under the number), so after stripping 2 chars the continuation has a leading space. Both tail.trimEnd() and line.trimStart() are applied at the join point.

it makes sense to unwrap the code blocks and diffs as well (the diffs show precise continuations so there shouldn't even be any guessing)
●
Two precise fixes needed:
1. Code blocks: remove the inFence early-return from unwrapProse — apply the same threshold joining inside fences, but skip isNewUnit detection since -, *, > etc. are code syntax there, not semantic units. 2. Diffs: joinDiffWraps currently only catches wrap lines. It also needs to join continuation removed/added lines (lineNum: null, same type as predecessor) — those have an explicit marker so there's no ambiguity at all.

=== User 0 code block:
●
Two problems revealed by the output:
1. The code block collapsed into one line — after each join the accumulated length stays ≥ 76, triggering the next join in a cascade. Fix: inside fences, track the original pushed line length separately and zero it after a join, so only the first continuation in a sequence gets attached. 2. joinDiffWraps still needs to handle removed/added continuations (explicit -/+ markers with lineNum: null) — that part already merged into the previous edit, just needs verification.

=== Code block:
●
Mid-word joins are showing up inside template literals (FileA ccess). The terminal can wrap at any character, not just word boundaries, so in code there's no reliable way to know whether a space separator belongs. Prose is safe — the space between words was consumed by the wrap, so we always need to restore it. Code is not — the break could be mid-identifier.
Reverting code blocks to the original inFence protection. Prose and diffs are clean; code stays as-is.

=== Code block (should be untouched):
●
Clean. Summary of the final state:
Prose (unwrapProse) — applied to user turns and assistant text blocks. Lines ≥ 76 chars (the terminal's 80-col limit minus the 2-char indent prefix, with a 2-char safety margin) are joined with the next non-blank, non-structural line. isNewUnit stops joins at ●, ❯, ⎿, #, list markers, etc. Diffs (joinDiffWraps) — two join cases, both unambiguous: - wrap type (context line wraps with no type char): joined to predecessor - removed/added with lineNum === null (explicit -/+ continuation): joined to same-type predecessor Code blocks — left untouched. The wrap can happen mid-identifier ([IO.FileA / ccess]), and there's no reliable way to know whether to insert a space or nothing. Prose wraps always need a space restored (the space was consumed at the boundary); code wraps sometimes need a space and sometimes need nothing. The fenced-block comment in the parse function explains why.
