fix(session): preserve stamped turns and shared journal ancestors (#7180) [skip ci]

Keep the contributor's original commits and their Windows Console feature fix.
A stamp enriches an unshared user entry. Preserve authored payload, cache
markers, runtime ownership, conflicting stamps and preexisting branch history.
Use the same prefix semantics for saved outcomes and TUI refresh. Record
the strictly changed byte offset separately for token accounting.

42 focused tests passed. The macOS PTY sent the same text twice on purpose,
one Enter at a time. The loopback provider saw exactly two requests, the two
answers stayed on the active path, and it matched the persisted transcript.
The linked Windows incident has not been reproduced. Refs #7178.

+- **Composition on the first request:** `execute_tools` accepts a bounded named batch from the current MCP catalog, with argument names from its allowed members and the same nested gate as a JavaScript program. Exact tool-name searches work with regex anchors. Stream receipts hash the executable in the background; `CODEWHALE_TIMING=1` reports phase durations. (CW-7649)

 - **Runcrate is a bundled provider:** `runcrate` reaches the OpenAI-compatible host at `https://api.runcrate.ai/v1` with `RUNCRATE_API_KEY`, and model ids come from its public `GET /v1/models` listing. Thanks @heydryft for the request and the vendor details. (#7085)
 - **MCP connection status reaches the model:** one existing history snapshot now records permitted configured, connecting, failed, authorization-required, unknown and connected servers, with bounded inert names and no raw errors. Stale status and server guidance are withdrawn on contention, configuration/scope changes and restore; observation does not connect servers or promise callable tools. (#6866)
 - **Bundled-skill policy:** `[skills.bundled]` separates automatic, authoritative and disabled installation from discovery, with per-name selection, disable and explicit-only controls. Aliases share policy; disabled shipped copies reveal user alternatives. Modified and managed files remain intact, and doctor plus `/skills inspect` show the effective policy. (#7066)
-- **Configurable skill routing index:** `[skills] listing_max_description_chars` and `listing_budget_fraction` control the shared parent/child catalogue. Defaults stay 400 characters and 5% of the route window, within the existing total bounds. Load warnings, localized inspect notes and `/context` explain shortening; full skill loading stays available. (#7073)

 ### Fixed
 
+- Saving a user turn when the Engine adds its metadata preserves the journal entry and its place in history. Sessions with a fork keep the earlier branch intact. Thanks [@SparkofSpike](https://github.com/SparkofSpike). ([#7180](https://github.com/codewhale-hq/Codewhale/pull/7180))
+- **Star keycaps stay intact in Markdown (#7176):** plain and escaped text
+  preserve the full grapheme, and a keycap cannot open emphasis. The separate
+  Windows Terminal font-fallback issue remains unqualified. Thanks
+  [@SparkofSpike](https://github.com/SparkofSpike).
 - **Codewhale runs from a HarmonyOS user directory (#7168):** on HarmonyOS hmdfs (the 2in1 `/storage/Users/currentUser` mount), which reports its own owner and a group-writable mode for every object and refuses `chmod` and advisory locks, a GUI start failed one feature at a time — the workspace lease, the owner control socket, then the OAuth credential directory. Private directories, the secret store and credential files now probe the mount once, keep the strict ownership check everywhere it can be expressed, and on a mount that cannot express ownership still enforce no-follow, single-link and atomic publication, with one warning naming what the mount reported. A filesystem without advisory locks serialises secret-store writes within the process instead of refusing; a held lock is still contention. Not observed here on a real HarmonyOS device. Thanks [@gaord](https://github.com/gaord).
 - **Notes stop swallowing a backslash:** a transcript note is machine-generated and names paths, but it went through the markdown renderer, where CommonMark §2.4 reads a backslash before ASCII punctuation as an escape. A note naming `C:\Users\asus\.codewhale\setup_state.json` therefore printed as `C:\Users\asus.codewhale\setup_state.json` — a directory that does not exist, in the one line a user would copy to find the real one. Notes are now escaped where they are rendered. Fenced blocks, and lines carrying inline code or a table row, are passed through untouched, because the renderer already copies those verbatim and doubling a backslash inside one would print it doubled.
 - **Setup state survives a second instance:** two running Codewhale windows share one home, and both rewrite `setup_state.json` when the provider or model changes. The replacing rename is now retried briefly when the destination is held open for a read — Windows refuses it outright while that handle lives — instead of surfacing a write the caller could have made. The failure message also carries the underlying I/O error instead of only the outer context, so the next occurrence is diagnosable.

 - **Compact approvals keep their authority visible:** cards show three choices and default to Deny. An exact saved rule requires its scope preview on screen. Shortcuts for additional actions require opening Details; a hidden saved-rule choice never falls back to granting the session.
 - **Quicker everyday navigation:** top-level help separates everyday and advanced commands, `doctor --all` expands path/backend details, and the launch screen labels how to resume recent work. Up selects the newest recent session. Whale cameos stay out of transcript text.

 ### Fixed
 
+- Saving a user turn when the Engine adds its metadata preserves the journal entry and its place in history. Sessions with a fork keep the earlier branch intact. Thanks [@SparkofSpike](https://github.com/SparkofSpike). ([#7180](https://github.com/codewhale-hq/Codewhale/pull/7180))
+- **Star keycaps stay intact in Markdown (#7176):** plain and escaped text
+  preserve the full grapheme, and a keycap cannot open emphasis. The separate
+  Windows Terminal font-fallback issue remains unqualified. Thanks
+  [@SparkofSpike](https://github.com/SparkofSpike).
 - **Codewhale runs from a HarmonyOS user directory (#7168):** on HarmonyOS hmdfs (the 2in1 `/storage/Users/currentUser` mount), which reports its own owner and a group-writable mode for every object and refuses `chmod` and advisory locks, a GUI start failed one feature at a time — the workspace lease, the owner control socket, then the OAuth credential directory. Private directories, the secret store and credential files now probe the mount once, keep the strict ownership check everywhere it can be expressed, and on a mount that cannot express ownership still enforce no-follow, single-link and atomic publication, with one warning naming what the mount reported. A filesystem without advisory locks serialises secret-store writes within the process instead of refusing; a held lock is still contention. Not observed here on a real HarmonyOS device. Thanks [@gaord](https://github.com/gaord).
 - **Notes stop swallowing a backslash:** a transcript note is machine-generated and names paths, but it went through the markdown renderer, where CommonMark §2.4 reads a backslash before ASCII punctuation as an escape. A note naming `C:\Users\asus\.codewhale\setup_state.json` therefore printed as `C:\Users\asus.codewhale\setup_state.json` — a directory that does not exist, in the one line a user would copy to find the real one. Notes are now escaped where they are rendered. Fenced blocks, and lines carrying inline code or a table row, are passed through untouched, because the renderer already copies those verbatim and doubling a backslash inside one would print it doubled.
 - **Setup state survives a second instance:** two running Codewhale windows share one home, and both rewrite `setup_state.json` when the provider or model changes. The replacing rename is now retried briefly when the destination is held open for a read — Windows refuses it outright while that handle lives — instead of surfacing a write the caller could have made. The failure message also carries the underlying I/O error instead of only the outer context, so the next occurrence is diagnosable.

 The renderer favors `Use when:` triggers, shortens descriptions before falling back to names, and reports shortened/omitted entries. Descriptions exceeding the configured cap without a trigger also produce a load warning. `/skills inspect` shows a localized note with the same effective cap, and `/context` repeats the loss count. `load_skill name="list"` and exact-name loading retain full text.

Plan, Work, and Operate\nuse the same primitive identities. Plan centrally refuses `write`, `edit`, and\n`bash`; Work and Operate still pass those calls through approval, sandbox,\ntrusted-path, repository-law, and managed-policy gates. Full Access changes\nordinary approval behavior but does not bypass hard safety or repository law.\n\n`update_plan` remains registered only for saved-artifact compatibility and is\nnot model-visible. `tasks`, `Git`, `Run`, `Web`, `remember`, and other\nspecialized capabilities are searchable rather than first-turn ceremony.\n\nOn the TUI's default (calm) shell card the Bash description is the headline,\nshown as written apart from stripped terminal escapes, collapsed whitespace and\na length bound, and the command sits on its own `$` row directly under it in\nevery state and at every width, including automatic runs. A card without a\ndescription leads with the `$` command instead. The labeled card\n(`show_tool_details = true` with `calm_mode = false`) keeps the command in its\nheader and the description as a muted `note:` row. The description nLine truncated

Use\n`config.toml`, CLI flags, or values exported by the launching shell for those\nexplicit control-plane settings. `.env` is read from a stable regular-file\nhandle, is capped at 1 MiB, and symbolic links, reparse points, and multiply\nlinked files are rejected.\n\n## Reading and checking configuration from the CLI\n\n`codewhale config get <key>` reads scalar keys, whole tables such as `tools`,\nand nested paths such as `tools.user_input_timeout_seconds`. Displayed tables\nand nested values apply the same recursive credential redaction as `config dump`.\n\n`config set` supports its named scalar keys and the provider, route, and\nnotification commands. It refuses a key that nothing reads and suggests the\nnearest real key (`config set calm_mod on` names `calm_mode`). A settings.toml\nkey such as `calm_mode` or `tool_collapse` is validated and written to the\nuser-global settings.toml, not config.toml; `config get` reads it back from\nthere even when an old config.toml copy (which nothing reads) is still present,\nand names that copy so you can `config unset` it. Settings keys have no project\nscope, so `--project` refuses them. A config.toml key is checked against the\ntype its reader expects and stored as a TOML boolean or number where the\nreader needs one (`yolo = true`, `max_subagents = 4`); `reasoning_effort`\naccepts the same aliases as `/effort` (#6563). Other dotted writes fail before\nmodifying the file and name the TOML table to edit. For example, set a tools\ntimeout in the file as:\n\n```toml\n[tools]\nuser_input_timeout_seconds = 0\n```\n\n`codewhale config doctor` checks credential presence and endpoint shape, and\nwarns about each config.toml root key that nothing reads: a settings.toml key\nleft in config.toml is named as misplaced, and any other unread key gets a\ndid-you-mean. Keys read by any runtime reader are not reported. The warnings do\nnot fail the check, and a clean result does not validate every runtime setting's\nvalue (#6083, #6563).\n\n## Constitution, project instructions, and repo authority\n\nCodewhale has several instruction surfaces. They are deliberately separate so a\npersonal constitution, repo policy, project instructions, and runtime security\ncontrols do not blur together.\n\n- **Bundled global Constitution** — the compiled base law in the binary. It is\n  the default floor for every session.\n- **User-global constitution** — the normal guided setup output. Manage it with\n  `/constitution` or `/setup`; Codewhale stores structured data at\n  `$CODEWHALE_HOME/constitution.json` (default `~/.codewhale/constitution.json`)\n  and renders it into a separate `<codewhale_user_constitution>` prose block.\n  This can express preferences and stop conditions, but it does not change\n  runtime approval policy, sandbox, shell, network, trust, or MCP permissions.\n- **Repo-local constitution** — optional project policy in\n  `.codewhale/constitution.json`, described below.\n- **`AGENTS.md`** — cross-agent **project instructions** (prose). This is the\n  canonical file for \"how should an agent work in this repo.\" Run `/init` to\n  scaffold one. Instruction files written for other tools (`CLAUDE.md`,\n  `.claude/instructions.md`, `.cursorrules`, `.github/copilot-instructions.md`\n  and similar) are read only when you opt in with the top-level\n  `project_instruction_imports` key, for example `[\"claude\"]`, `[\"cursor\"]` or\n  `[\"all\"]` (see `config.example.toml`); Codewhale warns when it finds one it\n  did not load.\n\n  Codewhale reads one instruction file per directory, from the repository\n  root down to the workspace, and puts your global instruction file (such as\n  `~/.codewhale/AGENTS.md`) in front of them. The nearest scope reads last\n  and wins: the workspace file overrides its parents, and project files\n  override the global file. Global and project instructions are budgeted\n  separately in estimated tokens (see [Instruction budget](#instruction-budget-instruction_budget-6526)\n  below): a scope over its budget drops whole files from the broadest end\n  first, and a single file larger than the remaining budget keeps its head\n  with a marker that names the bytes and tokens dropped. A file keeps at most\n  its first 100 KiB, and a file larger than `file_max_bytesLine truncated
