     Cleanup gives back what it was given, near enough, so a reply several times

+    left alone: there the same runaway is rare, and a ceiling would cut the
+    minutes short instead.
+
+    The answer's share is the transcript's length in characters spent as a
+    budget in tokens, so what it really allows is two to four times the
+    transcript depending on how well the language tokenises. Turkish sits at the
+    tight end of that and still has room to spare for a reply that is meant to
+    come back the same length it went in.
+
+    Thinking is added on top of that share rather than taken out of it. Sharing
+    one budget is what makes turning thinking up quietly cost the answer, and on
+    a short dictation the 512 floor is the whole budget, so the answer is what
+    goes missing first.
+
+    `context` is what the server was started with, and the whole of it is the
+    real limit whatever is asked for here: a ceiling above it is not a ceiling,
+    because the runaway it exists to stop would run to the end of the context
+    instead. So the ceiling is held below what the prompt leaves. Two characters
+    to the token is under any tokeniser's rate for natural language, Turkish

+"""The parts of AppKit a dictation needs on macOS and Qt does not reach.
+
+Two jobs, both about staying out of the user's way.
+
+The first is keeping the indicator on screen. Qt draws it as a tool window,
+which on macOS is an NSPanel, and an NSPanel is hidden by the system the moment
+its application stops being the active one. For a dictation indicator that is
+exactly backwards: you press the shortcut inside some other program, so Dikte is
+never the active application, and the one window that has something to say
+disappears as soon as you look away from it. Three settings AppKit has and Qt
+does not expose:
+
+  hidesOnDeactivate = NO      stay put when another application comes forward
+  collectionBehavior          show on whichever desktop is in front, including
+                              over a full screen window, and stay out of Cmd+Tab
+  nonactivating panel         come to the front without bringing Dikte with it
+
+The second is putting the front back. Opening the microphone activates Dikte
+whatever the indicator does, so app.py watches for that and calls activate()
+here. See _give_the_front_back() there for the measurement.
+
+Done through the Objective-C runtime rather than a binding, because Dikte has no
+third party Python packages and this is a handful of messages to three objects.
+The runtime is loaded in _appkit() rather than at import, the way paste.py loads
+its frameworks in _macos_api(): that is the one function a test fakes, and it is

+# The Vulkan whisper-server bundle
+
+whisper.cpp publishes a CPU-only archive for Linux, so the graphics card on a
+Linux machine is out of reach through the Download button. This directory
+builds the archive upstream does not: `whisper-server` with a dynamic Vulkan
+backend next to the CPU ones, for x86_64, against the Ubuntu 22.04 runtime
+contract.
+
+It is published as a release of Dikte's own, `whisper.cpp-v<version>`, marked
+as a prerelease and kept off Latest so that neither the update check nor the
+download page picks it up. `dikte/ggml.py` fetches it by tag and installs it
+only when the archive's digest is the reviewed one; anything else falls back
+to upstream's CPU archive, and the settings window says when it did.
+
+## Publishing a new bundle
+
+1. Enable GitHub's immutable releases setting for the repository, and give the
+   `dependency-release` environment a required reviewer. Both are repository
+   settings, not something this workflow can do for itself.
+2. Run **whisper.cpp Vulkan bundle** on `master` with the new version and its
+   peeled commit, `expected_sha256` empty and `publish: false`. The run builds
+   the archive and reports its digest; without a reviewed digest it refuses to
+   publish, which is what the first run is for.
+3. Review that digest against a build of your own, then run the workflow again
+   with the same version and commit, `expected_sha256` set to it, and
+   `publish: true`. Approve the environment when it asks.
+4. Write the same version, tag and digest into `MANAGED_WHISPER_RELEASE`,
+   `MANAGED_WHISPER_VERSION` and `MANAGED_WHISPER_SHA256` in `dikte/ggml.py`,
+   and into `REVIEWED_WHISPER_VERSION` and `REVIEWED_WHISPER_SHA256` in the
+   workflow. `tests/test_packaging.py` holds the two sides together.
+5. Ship a Dikte release. Until one goes out, nobody's Dikte knows the new
+   bundle exists.
+
+## What this costs, and what it does not promise
+
+The digest lives in Dikte's source, so a backend update is a Dikte release.
+Linux x86_64 machines with a Vulkan loader stay on the pinned whisper.cpp
+version until step 5 happens, while every other platform follows upstream's
+newest release on its own. That is the deliberate trade: an executable Dikte
+downloads is not allowed to change without a reviewed digest behind it.
+
+The build is deterministic between two runs of the same builder, not across
+time. The base image, the CMake tarball, the LunarG packages and the direct
+apt packages are pinned by digest or version, but the Ubuntu and LunarG
+repository metadata behind them is not, and LunarG drops superseded packages.
+A rebuild months later can fail to resolve, or resolve to something that
+produces a different digest. Treat the published archive as the artifact, not
+as something reproducible on demand: a version bump means building,
+validating, reviewing the new digest and updating the pinned tuple together.
