 All notable changes to CodeCraft. Versions follow [Semantic Versioning](https://semver.org/);
 until 1.0, minor versions may contain breaking changes.
 
+## [v202611-00040] – 2026-11-15
+
+### Fixed
+
+- **Images you upload reach Claude Code**: its chats read the history without the image bytes, so the
+  files it was pointed to were empty. Images without data are no longer written as empty files.
+
+## [v202611-00039] – 2026-11-15
+
+### Changed
+
+- A chat's colour no longer tints the chat background (pane, message field, agent bubbles, top bar
+  fill); it still marks the top bar line, the list entry, the badge and your own bubbles.
+
+### Fixed
+
+- **Claude Code can ask questions again**: its `AskUserQuestion` was always rejected; now the question
+  appears as a question card in the chat (single and multiple choice) and the answers go back to it.
+
+## [v202611-00038] – 2026-11-15
+
+### Changed
+
+- The chat menu in the sidebar has a **Delete** entry (with the question about the chat's own folder);
+  colour and icon selection moved out of it – they remain in the ⋯ menu inside the chat.
+
+## [v202611-00037] – 2026-11-15
+
+### Added
+
+- **Deleting a chat asks about its folder**: if the chat has a folder of its own (inside your folders,
+  not shared with any other chat, no project folder), you can delete it with the chat – with the
+  number of files, size and a warning for git repositories. The server checks again before deleting.
+
+## [v202611-00036] – 2026-11-15
+
+### Added
+
+- **Claude Code gets all CodeCraft tools** (image generation, 3D, OpenSCAD, browser, scheduling,
+  diagnostics, reverse engineering, skills, ask_user, the server's MCP tools …) over an MCP bridge,
+  as `mcp__codecraft__<name>`. Tools the CLI has itself (read, write, edit, bash, grep …) are not
+  offered twice. Calls go through the usual approval cards and rules.
+
+## [v202611-00035] – 2026-11-15
+
+### Fixed
+
+- Creating an SSH key failed with "No user exists for uid 99": `ssh-keygen`, `ssh-keyscan` and
+  `ssh-add` get the same passwd workaround as `ssh`.
+
+## [v202611-00034] – 2026-11-15
+
+### Fixed
+
+- `ssh`, `scp` and `sftp` failed with "No user exists for uid 99" because the container runs as a uid
+  without passwd entry; the image now wraps them with nss_wrapper (also used by the key wrappers).
+
+## [v202611-00033] – 2026-11-15
+
+### Added
+
+- **SSH keys** (Settings → Account): generate (ed25519) or import keys; agents, the terminal and the
+  git panel use them automatically for `ssh`, `scp`, `sftp`, `rsync` and git over ssh. Hosts are
+  trusted on first contact; the public key can be copied for the server's `authorized_keys`.
+
+## [v202611-00032] – 2026-11-15
+
+### Fixed
+
+- Agents now know that git credentials are stored (hosts, no secrets) and no longer search the
+  environment for them; the system prompt explains `git push` just works and how to read the token
+  for REST calls without printing it. Claude Code runs get the user's git credentials and identity too.
+
+## [v202611-00031] – 2026-11-15
+
+### Fixed
+
+- Images read by an agent (Read tool) are shown right away; with Claude Code they were dropped.
+
+## [v202611-00030] – 2026-11-15
+
+### Added
+
+- **`/clear`**: the model forgets the conversation so far; the chat keeps showing it, a divider marks
+  the cut. Also starts a fresh session with Claude Code.
+
+## [v202611-00029] – 2026-11-15
+
+### Added
+
+- **Statistics**: sections and models fold; long history with a year filter (monthly bars for long
+  ranges); export of the shown figures as XLSX (all tables) or CSV (one table).
+- **Prompt snippets**: own text blocks, inserted with `/name` in the message field (Settings → Account).
+- **Read-only links**: share a chat's text with people without an account (valid 1–90 days, revocable).
+- **Git panel**: the small model suggests a commit message for the staged changes.
+- **Weekly review** as a push notification (Mondays 08:00: chats, checks, costs; opt-in).
+- **Speech-to-text on the server** (`server.transcribe_model`) for browsers without dictation (Firefox).
+- **Offline**: the chat list and the last opened chats stay readable without a connection.
+- **Planning model** setting: plan mode always uses it, other modes the chat's model.
+- **Automations** send their report as a push notification when a run ends (switchable).
+
+### Fixed
+
+- fal.ai: the provider check no longer reports "API key rejected" when only the model listing is not offered.
+
+## [v202611-00028] – 2026-11-14
+
+### Added
+
+- **18 more chat icons** (gamepad, computer, food, coffee, home, book, code, camera, cart, heart,
+  star, globe, calendar, car, plane, bulb, money, palette).
+
+### Changed
+
+- **The ⋯ menu of a message sits inside its bubble** (in the foot next to the time, also in your own
+  bubbles); its popup opens upwards within the bubble and is no wider than the bubble.
+
+## [v202611-00027] – 2026-11-14
+
+### Added
+
+- **Chat bubbles:** your messages on the right in their own colour (the chat's colour tag if it
+  has one), the agent's answers on the left; tool-only steps and system notes stay without bubble.
+- **Icons for chats:** pick one of 22 icons in the ⋯ menu (chat and session list); it shows in the
+  list, the top bar and the project page, in the chat's colour, and is part of the project default.
+
+### Changed
+
+- **Colour tags are more vivid and more distinct:** eight fixed hues (new: pink), drawn with a
+  lightness that fits the theme (light/dark) and the highest chroma sRGB allows, so no two tags
+  look alike; backgrounds are tinted more strongly. Browsers without relative colours keep the
+  theme's own colours.
+
+## [v202611-00026] – 2026-11-14
+
+### Added
+
+- **Claude Code as an engine:** chats with a "Claude Code" model (Opus, Sonnet, Haiku, default) are
+  run by the `claude` CLI. Its events become normal chat messages; its tool approvals go through
+  CodeCraft's permission system (cards, push buttons, "allow for this project", diffs, sandbox).
+  Sign in from the web UI (Settings → Account → Claude Code: open the sign-in URL, paste the code),
+  see the CLI version and install updates (admins; installed into the persistent home). The Docker
+  image now contains the CLI.
+- **Small models (8k context) for side tasks:** `small_model` jobs cut their input to the model's
+  context window. New with it: a one-line status per chat in the session list, "What does this
+  do?" on approvals, and "Plan as automation" (drafts job instructions from a chat).
+- **Mobile:** the top bar no longer pushes the page sideways (extra actions moved into the ⋯ menu);
+  an image viewer for all images (zoom, swipe between images, mark up and attach to the message,
+  use in the message); jump to the previous own message; message menu (copy, quote, fork from
+  here, edit and resend); date and time under every message.
+- **Approvals:** push notifications can allow or reject right away; "always allow in this project"
+  is remembered per folder (never for dangerous commands) and can be revoked in the ⋯ menu.
+- **Changes per turn:** files changed by a turn with diffs and "roll back to before this turn".
+- **Check after each turn:** a command per project (e.g. `cargo test`) runs after turns that
+  changed files; green/red badge with output and "let the agent fix it".
+- **Colour tags for chats:** tinted chat background and a badge in the list, drawn in the colours
+  of the active theme.
+- **Project defaults, project page, offline queue:** new chats in a folder inherit model, mode,
+  colour, instructions and folder; a timeline of a project's chats (sidebar → project → ⋯);
+  messages written without a connection are sent when it is back.
+
+## [v202611-00025] – 2026-11-12
+
+### Fixed
+
+- **Models did not find built-in tools via `mcp_search`** (e.g. `generate_3d` in a chat that
+  had just been switched from plan to build): the search only looked at MCP servers. It now also
+  lists matching built-in tools and says whether the current mode has them ("available – call it
+  directly", or "not in the read-only mode plan – ask the user to switch to build").
+
+## [v202611-00024] – 2026-11-12
+
+### Added
+
+- **3D models with fal.ai (`generate_3d`):** from an image (a project file or one pasted into the
+  chat, optional back/left/right views), from a text prompt, or from an image steered by a prompt
+  (the image is refined with the prompt first – the 3D models take no text with an image).
+  Styles textured, geometry (untextured, for 3D printing) and low-poly, optional PBR. Uses fal.ai's
+  queue (takes minutes, with progress), saves a GLB plus a preview image, books the cost.
+  Defaults: Hunyuan3D v3 image-to-3D / text-to-3D (`[images] model_3d`, `model_3d_text`); Tripo
+  and Trellis endpoints work too.
+- The chat card offers "Open in the 3D view"; the media overview lists 3D models (also STL/3MF
+  written by the agent) with their previews.
+
+## [v202611-00023] – 2026-11-12
+
+### Added
+
+- **Tokens and cost under every answer:** a small line under each answer of the model shows the
+  tokens sent/received and the cost of all requests of that turn.
+
+### Fixed
+
+- **Total cost of chats stopped growing (opencode Go):** opencode now reports plan requests as
+  "nothing charged" (cost 0, usage in `allowance`), and CodeCraft took the 0. Plan requests are
+  valued at the model's list prices again; earlier ones are corrected once on start.
+- **Saving opencode Go models failed after fetching prices** ("data did not match any variant of
+  untagged enum ModelEntry"): opencode lists cache prices per duration for some models
+  (`{"30m": …, "12h": …}`); the shortest duration is used now.
+- The chat title in the top bar no longer shrinks to a single letter when there are many chips.
+
+## [v202611-00022] – 2026-11-11
+
+### Added
+
+- **Theme "Tintenblau"** (dark: ink blue with cream text; light: paper with dark ink), from the
+  Tintenblau desktop theme; also in the terminal client.
+
+## [v202611-00021] – 2026-11-11
+
+### Added
+
+- **Commits of agents name the model:** every `git commit` an agent makes gets the trailer
+  `Co-Authored-By: <model> (<provider>) via CodeCraft` (a git wrapper in the agent shell, also in
+  the sandbox; your own commits stay unchanged). The text is set under *Settings → General*
+  (`server.commit_trailer`, `{model}`, `{provider}`, `{model_id}`; empty = off).
+
+## [v202611-00020] – 2026-11-11
+
+### Added
+
+- **Reverse engineering outside craft:** *Settings → Agents & commands* can give any mode the
+  `binary_info` and `decompile` (Ghidra) tools; the clean-room rule stays a craft rule.
+- **Raw firmware in `decompile`:** optional `processor` (Ghidra language id, e.g.
+  `ARM:LE:32:Cortex`) and `base_address` for images without a file format (.bin, converted .hex).
+- **Skill "reverse-engineering":** how to identify, decompile and explore programs and firmware
+  (processor table for common chips, HEX conversion, notes in `analysis/`).
+

+name: reverse-engineering
+description: Analyse programs and firmware – identify the format, inspect with binary_info, decompile with Ghidra (decompile tool, also raw firmware with processor/base address), explore the output and write down findings. For file formats, protocols, bugs and interoperability.
+---
+# Reverse engineering of programs and firmware
+
+You analyse a binary to understand how it works – a file format, a protocol, an algorithm,
+a bug, or how to talk to a device. Work from cheap to expensive and write down what you learn.
+
+Only analyse binaries the user owns or may analyse (their own builds, their devices, programs
+for interoperability). Decompiled code is third-party material: never commit it and never paste
+it into the user's source – describe behaviour in your own words.
+
+## 1. Identify
+- `file <path>` – format, architecture, stripped or not.
+- Executables and libraries (PE .exe/.dll, ELF, Mach-O): `binary_info` – sections, imports,
+  exports, strings. Imports and strings tell a lot (file names, error messages, protocol
+  keywords, library names) before any decompiling.
+- Archives and update packages: unpack first (`unzip`, `7z x`), then identify the parts.
+- Intel HEX / S-record firmware: convert to a raw image –
+  `objcopy -I ihex -O binary fw.hex fw.bin` (the lowest address in the HEX file is the base
+  address). An ELF from the firmware's build (e.g. `zephyr.elf`, `firmware.elf`) is far better
+  than a raw image: symbols and addresses are included – look for it first.
+- Raw images: look for clues with `strings -n 6 fw.bin | head -200` and
+  `python3 -c` one-liners (vector table, magic numbers, embedded file systems).
+
+## 2. Raw firmware: processor and load address
+`decompile` needs both for images without a file format:
+
+| Chip family | `processor` | typical `base_address` |
+|---|---|---|
+| ARM Cortex-M (STM32, nRF52, RP2040, SAMD) | `ARM:LE:32:Cortex` | STM32 `0x08000000`, nRF52 `0x00000000`, RP2040 `0x10000000` |
+| ARM Cortex-A / ARMv7 | `ARM:LE:32:v7` | from the bootloader / datasheet |
+| AArch64 | `AARCH64:LE:64:v8A` | |
+| ESP32 (Xtensa) | `Xtensa:LE:32:default` | per segment (use the ELF if possible) |
+| AVR (Arduino) | `AVR8:LE:16:atmega256` or `AVR8:LE:16:default` | `0x0` |
+| MIPS (routers) | `MIPS:BE:32:default` or `MIPS:LE:32:default` | e.g. `0x80000000` |
+
+Cortex-M check: the first word of the image is the initial stack pointer (0x2000xxxx = RAM),
+the second the reset vector – it points just behind the base address. If the decompiled output
+is mostly garbage, the processor or base address is wrong: fix it and run again (results are
+cached per file *and* processor/address).
+
+## 3. Decompile
+- `decompile` with the path (plus `processor`/`base_address` for raw images). Large programs:
+  start with `max_functions` (e.g. 2000), widen when needed.
+- Output in `.codecraft/decompiled/<name>/`: `functions.tsv` (address, name, size, file,
+  signature), `functions/*.c`, `strings.tsv`, `imports.tsv`, `exports.tsv`.
+
+## 4. Explore
+- Start from what you know: a string, an import or an export.
+  `grep -l "SetCommState" .codecraft/decompiled/<name>/functions` finds the functions that use it.
+- Follow the calls by reading the functions; note addresses (`FUN_00401a30`) as you go.
+- Broad searches through thousands of functions: delegate them to an `explore` subagent with a
+  precise question and let it report file:line.
+- File formats: compare the reading/writing code with a sample file (`python3` to dump the bytes)
+  until every field is explained.
+
+## 5. Write it down
+Keep findings in `analysis/notes.md` (create it; it is not committed): structure of the
+program, important functions with addresses, data structures, file formats and protocols with
+field tables, open questions. Make sure `.gitignore` excludes `analysis/`, `original/` and
+`.codecraft/decompiled/`. At the end, report what you found and how sure you are – mark guesses
+as guesses.
