+# Package Generation
+
+This project supports generating both Debian (.deb) and RPM (.rpm) packages
+using CPack.
+
+## Manual Package Generation
+
+### Prerequisites
+
+- CMake 3.16 or later
+- Make or Ninja build system
+- For RPM packages: `rpmbuild` utility
+
+### Build Process
+
+1. **Create build directory:**
+   ```bash
+   mkdir -p build-package
+   cd build-package
+   ```
+
+2. **Configure with CMake:**
+   ```bash
+   cmake .. -DCMAKE_BUILD_TYPE=Release
+   ```
+
+3. **Build the project:**
+   ```bash
+   make -j$(nproc)
+   ```
+
+4. **Generate packages:**
+   ```bash
+   cpack -G DEB    # Generate Debian package
+   cpack -G RPM    # Generate RPM package (requires rpmbuild)
+   ```
+
+### Requirements for RPM Generation
+
+To generate RPM packages, you need `rpmbuild` installed:
+
+- **Ubuntu/Debian**: `sudo apt-get install rpm`
+- **CentOS/RHEL**: `sudo yum install rpm-build`
+- **Fedora**: `sudo dnf install rpm-build`
+
+### Package Contents
+
+The generated packages include:
+
+- **Main executable**: `/usr/bin/salmanoff`
+- **Shared libraries**: `/usr/lib/lib*.so`
+- **Device configurations**: `/usr/share/salmanoff/devices/` (preprocessed
+  .daps files)
+- **Documentation**: `/usr/share/doc/salmanoff/`
+
+### Installing Packages
+
+**Debian/Ubuntu:**
+```bash
+sudo dpkg -i salmanoff-0.00.004-x86_64.deb
+```
+
+**CentOS/RHEL/Fedora:**
+```bash
+sudo rpm -i salmanoff-0.00.004-x86_64.rpm
+```
+
+### Package Configuration
+
+Package metadata and configuration is defined in
+`cmake/CPackConfig.cmake`. This includes:
+
+- Package name, version, and description
+- Dependencies and recommendations
+- License information
+- File naming conventions
+
+### Troubleshooting
+
+- **RPM generation fails**: Ensure `rpmbuild` is installed
+- **Missing dependencies**: Check that all build dependencies are
+  installed
+- **Permission errors**: Ensure you have write permissions in the build
+  directory

+Ok: I realized I may be able to bridge async sequences without needing needing to make a bunch of functions async. The basic thing is:
+
+```
+funcThatCallsAsyncFuncsButWhoseSignatureIsItselfSync(ComponentThread &ct)
+{
+  std::atomic continuationCondition(false);
+
+  async_call(ct, [] {
+    // Do stuff that will enqueue events on ct.

+     * here, may not actually be the thread that owns
+     * ct, in which case, ct's owner will dequeue the stuff
+     * that async_call() sent it to do, then conclude its
+     * processing. It may or may not send a message back
+     * to the thread executing this sync sequence here.
+     *
+     * If we are the same thread as ct, then wonderful:

+     * it, then conclude the processing. We may or may
+     * not send a message back to ourself at the end of
+     * the processing but it doesn't matter since we'll
+     * have to check the condvar in the loop post-
+     * conditions before the next iteration.
+     *
+     * The problem is the first case where ct is a foreign
+     * thread which may not send us a wakeup message
+     * when condvar has been modified, and we may
+     * hypothetically never get another signal from any
+     * other thread.
+     * This can be solved by just ensuring that this thread
+     * always gives a callback to async_call() which first
+     * modifies condvar, and then sends an empty message
+     * to itself.
+     */
+    ct.run_one();
+    if (continuationCondition.load()==true
+      ||!ct.isRunnable())
+    {
+      break;
+    }
+  }
+
+  /* We've now bridged the async calls into this
+   * sync function's body without losing any
+   * event responsiveness for the main loop.
+   */
+  // Continue executing normally...
+}
+```
+
+This should be a complete solution for async bridging.
+
+Now let's try it first in the sendHandshake sequence. We'll try to use non-blocking socket api calls to send the heartbeat and wait for a response asynchronously. Don't use boost:asio:socket functions because they cause a segfault due to a bug (see /CMakelists.txt). To wait for events on the socket, setup boost to wait on the socket or bind FD.
+
+Async_call is OBVIOUSLY NOT a function you're expected to implement. It's merely a placeholder for any async sequence we call inside of the sync function.
+
+You're expected to get rid of the io_context auto-scope object inside of executeHandshake, and use the stored Device.componentThread's io_context instead. You are expected to refrain from associating Device.componentThread.io_service with any boost::asio::socket stuff. You will have to write manual posix socket api code, and use a boost::file_descriptor to catch wakeup events on the socket from the UDP events like recv-data-ready.
+
+You're basically going to break up executeHandshake into a series of lambdas, but use the pattern I described above to keep it as one synchronous function by bridging it. executeHandshake is the synchronous function that must remain synchronous to its caller. Internally, you must split up executeHandshake into several lambdas, and then at the end you set the condvar and post a message back to CompnentThread::getSelf()->io_service. Then, since executeHandshake() has a bridging sequence that loops and calls run_one() until the condvar is set, executeHandshake will resume executing after that loop exits.
+
+Makes sense?

+# Negtrin path reasoning:
+
+This file is intended to enable me to trace the path of negtrin through a mind. This path of reasoning is important because it allows me to link my way from the understanding of the genesis of implexing, to understanding an implementation path for implexing.
+
+## Motivation:
+
+We already understand that implexing begins with an intrin. The intrin prompts a search for the body surface which is experiencing the intrin. That surface is first implexed and stored away. Then subsequently, the cause of the intrin is sought out by implexing things that are relating/interacting with that body surface.
+
+Since it turns out that intrins are what motivate tabula rasa implexing, we can't move forward in designing our implexor code until we understand how the intrin path will work, since the implexor code will be invoked only as a consequence of, and in service to, the intrin processing code. We could implement something on the implexing side, but it would be a blind implementation.
+
+## What exactly are we trying to figure out?
+
+When intrins occur they occur at some device. Smo doesn't need a software-level representation of body parts, surfaces, or spots. The director can implex these and then build a proximity map for each intrin location by checking the causal relationships between the intrins when they occur. Intrins that co-occur in time and have a through-line of connecting co-occuring intrins are close enough to be proximally related.
+
+This is how the director can build damage map volitionally without requiring us to force it to.
+
+The design question we're pursuing here isn't the top-level notion of how to design a body map, but rather how to implement, at the software level, intrin implexing and delivery to the director.
+* What information precisely do we have to deliver to the director for it to successfully implex body surfaces?
+* At what point in the interoceptor data IRQ handling have we done enough work to enable the director to take over from that point?
+
+The answers to these questions will, as a side effect, also tell us how to design the implexor model for interoceptors, at least for intrin interoceptors anyway.
+* Should they be designed as NMI IRQs that the director can't ignore?
+* Should they be prioritized normal IRQs that the director can ignore?
+* Should they be IRQs at all? Maybe they should just be added to prioQ that the director polls.
+* Should they be asychronously processed at all? Maybe the director should have to poll the device service routines manually.
+
+Which of these implexor event interface designs is correct for the behavioural model?
+Also, can this model that we're designing for interoceptors also work for extrospectors? Do intrin percept events work the same as nontrin percept events?
+
+We still haven't fully crystallized the exact essential question we're trying to answer, but we have a list of questions. It appears that the fundamental question is what the correct behavioural model is for intrins and intrin processing. As a side-effect, we're also trying to figure out what the correct interface model should be between the interoceptor devices and the director. Finally, we're trying to figure out whether the design we come up with for interoceptors will be reusable for extrospectors.
+
+## Suspicions:
+
+### A hidden, implicit new subsystem:
+
+I suspect that part of the reason why I can't easily figure out the operations that need to be performed to properly process intrins is that the current set of subsystems I'm using to model the processing is insufficient. There may be additional, new functions that need to be performed by a new logically distinct subsystem altogether, or a new role to be assigned to a current subsystem.
+
+### Alternatively: my understanding of negtrins is simply inadequate:
+
+It could also be that the reason I can't understand how to implement the negtrin path is because I just don't fully understand what negtrins are, implementation-wise. I.e: I still don't understand how to make negtrins be experienced by the director as intrinsically undesirable.
+
+We do fully understand how to make postrins intrinsically desirable from an implementation perspective. But we don't understand fully how to make negtrins undesirable. Perhaps when we understand fully how to make the director __volitionally__ consider negtrins undesirable, the model will reveal itself.
+
+## Intrinsically undesirable negtrin model design:
+
+Postrins are represented as intrinsically desirable because the director will experience them as stupefactors. When a postrin occurs, the director will experience that as a stupifying experience, and will enter a HLT state, broken only by the suspicion that a greater state of stupefaction is possible.
+
+### Our implicit assumption: negtrins have an implementation meaning on their own terms:
+
+When the director dequeues a negtrin, what does it do? Perhaps our entire thought patterns around the default state of the director is simply wrong. We currently model the mind as having an idle loop, and then it can choose what to contemplate and pursue. Because of this thought model, we consider the question of how to treat negtrins to be a valid question: we treat negtrins as having their own intrinsic meaning.
+
+### What if negtrins only have meaning as frustrators relative to postrins?
+
+Consider what follows if we bias the entire implementation positively toward the direct pursuit of postrins. We treat the entire consciousness as a program whose fundamental goal is to enter a stupefaction loop on best postrin known to it. What would negtrins represent, in implementation terms? They would represent a frustrator. They would represent a dysvalue, automatically -- they would represent something that forces the mind to stop pursuing its highest known postrin and to attend to something cumbersome.
+
+In other words: negtrins don't represent a distinct fact from postrins. The damage map that negtrins help us to build isn't meaningful on its own terms. It's only meaningful in relation to the stupefaction loop pursuit that it forces us to turn away from.
+
+In this model, the stupefaction loop has intrinsic implementation meaning while the negtrin event has no intrinsic meaning: its meaning is merely that it diverts attention away from the pursuit and enjoyment of stupefaction.
+
+#### Supporting evidence:
+
+* A tabula rasa mind that has never experienced postrins literally has no desire to live. It has no positive goals.
+
+#### Detracting evidence:
+
+* A tabula rasa mind that has only experienced negtrins won't pursue any self-directed goals or desire to live, but it also will respond to negtrins. So even though this mind has never experienced a postrin, it will have a response (implying meaning and interpretation) to negtrins. If negtrins only have meaning relative to postrins, then this shouldn't be the case.
+  * Rejoinder: The tabula rasa mind which has never experienced a postrin will sit apoplectic in complete stasis, essentially in a "powered off" state. Is this not the same as a stupefied state? It seems that stupefaction is the default pursued state. To support the "default stupefaction pursuit" orientation, you'd only need to update your model of stupefaction to include net neutral states within your definition of postrins.
+
+### Stupefactor-Frustrator model:
+
+In this model, the mind doesn't receive nontrins as IRQs. Rather, it polls for them actively by "paying attention". Intrins are qualitatively different because they trigger IRQs. The mind is by default a procedural, polling system that volitionally polls its sensors. IRQs are intrins being injected.
+
+Intrins are fundamentally different because they force attention, and a neurological response. When a sufficiently intense postrin happens, you automatically stupefy. I have never been forcibly postrin-injected while trying to conduct some other activity, so I can't confirm this model. I've never had the indignity of being forcibly made to experience a postrin when I didn't volitionally choose to participate in allowing it. An ideal experiment would be to somehow have say, a coregasm while working out and not have chosen it, and see whether I can ignore it. This is the closest I can conceive of as a barriered-off experiment.
+
+For negtrins, I already know that a negtrin forcibly hijacks attention.
+
+## The fundamental problem is the canvas-director evaluation function:
+
+The fundamental unsolved problem is the contemplative evaluation whereby the canvas and director work together to produce a value judgment that considers intrins to be intrinsically [un]desirable.
+
+### Who does comparison? Canvas or Director?
+
+How does evaluation occur? Who does the comparison? We previously thought that the canvas does the comparisons but today we noticed that Director may be able to do them. In a sense, it makes more sense for Director to be the comparator because:
+
+#### Director as comparator:
+
+* If canvas merely helps director to transform mentents (we've finally found a good name), then director has more of an understanding of what specific instructions it's supposed to be giving to canvas.
+  * Our previous model of having canvas hold both goals and mentents made it difficult to really understand how director could ever "know" what instructions to send to canvas.
+  * With director holding goals, it can choose the types of scenes that need to be rendered in order to make comparisons and causal evaluations.
+* This makes the canvas implexing make more sense: the comparison is being done within director, but the canvas is making the comparison possible by rendering the mentents in orientations that enable canvas to compare them.
+* In a sense, this also makes it make more sense how compartmentalization occurs. A lot of the compartmentalization isn't within canvas, but rather it's between the director and canvas.
+
+#### Canvas as comparator:
+
+In a sense, we can think of it as director partitioning the canvas, and finding some way to refer to the mentents within different partitions. Director can then implex the rendered output from canvas and compare that way. Perhaps the director only compares, and the canvas holds both the mentents and the goals that the mentents are being compared against.
+
+But how can the director know whether the goal currently loaded into the "goal partition" of the canvas is indeed the goal that it desired to compare against? The canvas is a distinct mentent space from the director's comparison stage. The director-comparator model has the advantage of ensuring that the director can be certain that its current goal matches whatever is being rendered by the canvas for it to implex from.
+
+What we can do is synthesize a bit:
+* Have a special shared region between the canvas and director called the "goalspace". This is where the director stores its current goal mentents and the canvas can read from this space directly. Some synchronization will be necessary between the two, but overall, it should be fine. Canvas will only ever need to read from it so we can prolly synchronize it with an RW spinlock, avoiding the overhead of sleeplocks (mutex, sem, etc).
+
+I think we settle on the director as comparator, canvas as orienter model, with a shared goalspace between them.
+
+### Where are introspective/contemplative qualia experienced?
+
+In introspection/contemplation, canvas renders the scene into the buffers. Director implexes from the buffers. So in that sense, contemplative qualia are experienced when director implexes them from the buffers.
+
+For intrins, canvas renders them into the sense buffers and then director implexes them and "experiences" them. I don't know whether canvas' rendering act triggers IRQs -- probably not. Since director is paying attention to what canvas is rendering, there's no need to forcibly direct director's attention toward canvas' rendered output.
+
+### How does director's comparison yield the notion of intrinsic [un]desirability?
+
+Imagine director asking canvas to simulate the effects of some interaction that would bring about direct pleasure.
+
+Could it simply be that the director holds the goal of postrins as an innate comparison goal, and so when a comparison yields an intrin, it ends the need to compare, and the director just commits to action from then on?
+* Prolly not because we don't only figure out that an interaction will yield an intrin. With postrins for example, we figure out that they'll yield a postrin and then we spend a long time elaborately contemplating that postrin in self-indulgent scenarios.

+I just realized that my spinqueueing mechanism is highly power inefficient if a
+lock needs to be held across a "true async wait"—where the async sequence
+actually waits on a hardware bottleneck. In this case, the thread acquires the
+spinlock, then goes to sleep in the kernel schedq until some hardware event
+occurs, and is then awakened—all while still holding the spinlock.
+
+Meanwhile, other sequences running on other threads and contending for that lock
+will be Qspinning. This is acceptable if all I care about is maximum throughput:
+the Qspinning just re-posts the sequences back into the Q, and eventually
+they'll acquire the LockSet and proceed.
+
+Importantly, since the thread itself isn't slept in the kschedQ, it will be
+deQing and processing other sequences that aren't bottlenecked on the lock held
+by the sequence waiting for the hardware response. Throughput is indeed
+maximized.
+
+However, I just realized that if kernel mutexes expose FD events, I can apply
+this same logic to sleeplocks: I can wait on the sleeplocks asynchronously
+instead of synchronously. If I can make my asio::io_service wait on all the
+mutex FDs requested by sequences on the current thread, then in theory I can put
+the thread to sleep and know that when the mutex becomes available, I'll be
+awakened again.
+
+Hence, I can get the best of both worlds: maximum throughput and power saving.
+Instead of spinqueueing, we just add the lock FDs to an FD set to be waited on
+by asio. If any of those locks become available, the kernel scheduler will
+awaken our asioQ thread, and we can then awaken and retry the lock.
+
+## Boost asio queue-based sleep locking:
+
+Instead of using FDs, we can also try to use a fifo Q based mechanism: each lock
+is a spinlock and a fifo queue.
+
+Acquire:
+```
+lock(spinlock);
+q.push_back(self);
+head = q.peek_front();
+if (head == self) {
+	// We acquired the lock.
+	unlock(spinlock);
+	return;
+}
+
+unlock(spinlock);
+```
+
+release:
+```
+lock(spinlock);
+// Should get back ourself.
+q.pop_front();
+// Wake up the next request in the q.
+head = q.peek_front();
+if (head == NULL) {
+	// Nobody was waiting.
+	unlock(spinlock);
+	return;
+}
+
+head.thread_to_wake.getIoService().post([]{
+	// This lambda causes thread_to_wake to check this lock's
+	// Q and then proceed to execute since it now owns the lock.
+});
+unlock(spinlock);
+```
+
+Something like this: it causes the entire thing to be, at least ostensibly,
+in userspace -- though idk how Boost handles its queues internally.
+
+## Priortizing LockSets:
+
+One problem we have with a FIFO-based sleeping system is that it makes it very
+unlikely that LockSets will ever acquire all of their locks, if there are
+contenders for those same locks who only need to acquire one of the locks in
+that LockSet.
+
+We could theoretically give locksets an advantage by not making them backout
+if they fail to acquire all locks in their set. I.e: if they get 2/3, then they
+hold those 2 and then wait for the 3rd. This is problematic because it leaves
+room open for deadlocks in the form of T1 and T2 needing both LockA and LockB,
+but they acquire them in reverse order. I.e: T1 takes LockA and now waits for
+LockB; and T2 takes LockB and now waits for LockA. This will now happen among
+the LockSets if we don't impose backing out. It may be possible to avoid this
+using very careful lock ordering and dependency analysis but this project is
+asynchronous the locking is done in the async sequences and not in the sync
+accessor functions. So this kind of analysis is almost impossible to do.
+
+
+We need to think of a way to make the FIFOs biased toward LockSets so that they
+have an advantage over single-lock acquirers. Or else LockSet sequences will be
+starved.
+
+### Timed backoff:
+
+We could have Locksets be greedy and try to hold on to the locks they've
+acquired (say, 2/3 and then wait for the 3rd) but then be forced to backoff
+after a timeout.
+
+This introduces async event complexity and also the timeout we choose is almost
+guaranteed to be arbitrary.
+
+### Fractionally inserted FIFOs:
+
+We insert sequences with a LockSet.size() of 1, at the back.
+We insert all other sequences (>1) into first 1/LockSet.size()th position in the
+Queue.
+So a Lockset of size 2 will be inserted at the end of the first half of the
+items in the queue.
+A Lockset of size 3 will be inserted at the end of the first 33% of items.
+A lockset of size 4 will be inserted at the end of the first 25% of items.
+And so on.
+
+This ensures that higher LockSet.size()s will be prioritized ever higher, and
+at the same time they don't completely hog everything. Those single-lock
+sequences that have already naturally progressed past the fraction-mark of a
+given LockSet size will continue making progress toward the front.
+
+For queueing sequences with Locksets>1, we can enQ them on the FIFO of the first
+lock in their set. They'll back off each time anyway, so they'll always be
+re-trying from the first lock in their set each time.
+
+#### Impl details:
+
+We'd like to use std::unordered_set because insertion will require lots of
+moving items around, but we'll have to use std::vector because we need direct
+access to insert at arbitrary fractional indexes. It's unlikely the number of
+items in any lock's Q will ever be large enough to require lots of displacement,
+but welp there's no reason not to plan for scaling. Although if we end up
+needing scaling that's a symptom of a bigger problem...with scaling itself lol.
+There shouldn't be enough items blocked on a lock that we have to design the
+lock's queue to be scalable.
+
+### Inverted Fractionally acquired locksets:
+
+The previous ideas of fractionally inserted lockQs was okay, but the acquisition
+algo required that the async seq be at the front of a locks queue to
+successfully acquire that lock. That makes it almost impossible for Locksets>1
+to ever acquire all of their locks. If we add backoff to that, it basically
+means no lockset will ever acquire all of its locks.
+
+Instead what we now do is always insert at the rear (push_back()) and then when
+acquiring, we check to see if the sequence is in the first
+1/(1/(LockSet.size())), and if so, it successfully acquires the lock. I.e: if
+the sequence item isn't in the LAST 1/(LockSet.size()) items, then it succeeds.
+* For a lockset of size=1: It must be at the front of the queue.
+* Lockset.size=2: it must be in the first 50% of items.
+* Lockset.size=3: it must be in the first 66% of items.
+* Lockset.size=4: It must be in the first 75% of items.
+
+So this way larger LockSets are favoured, but 1-size locksets make progress.
+
+For performance:
+* We obv can just scan the smaller tail percentage for the item instead of
+  scanning the larger front percentage.
+* If we use a doubly-linked list, we can prolly keep the insertion iterator
+  and this way we won't have to actually find the item in the lockQ when we wish
+  to eventually remove it from the lockQ when releasing the lock.
+
+## Total overall design:
+
+### Asio queues and Lockvokers:
+
+Lockvokers are initially enqueued on a CompThread's queue. When the lockvoker
+first runs, it checks a flag to see if it has been "registered" into the queues
+for all locks in its set. If not, then it "registers" itself in each lock's
+ticketQ and then attempts to acquire each lock. Registration and acquisition
+are logically separate operations; and locks will often attempt acquisition
+many times after first registering, without needing to register again. Ideally
+we can implement a LockSet::registerAndTryAcquireAll() method, but that's for
+us to think about later.
+
+```
+/* We'll need to rename current class LockSpec to LockSet. */
+class LockSet
+{
+	/* Add this either inside of LockSet or outside of it -- depends on whether
+	 * it's we can get it to compile because I'm seeing some potential circular
+	 * definition dependencies.
+	 */
+	typedef std::pair<Qutex, LockerAndInvokerList::iterator>
+		LockUsageDesc;
+
+	/* Find a LockUsageDesc -- useful below */
+	LockUsageDesc &getLockUsageDesc(Qutex &criterionLock)
+	{
+		for (auto &reqLock: requiredLocks) {
+			if (reqLock.first == &criterionLock) { return reqLock; }
+		}
+
+		// Should never happen.
+		throw;
+	}
+};
+
+LockSet::register(LockerAndInvoker &lockvoker)
+{
+	for (auto &lock: lockset.locks) {
+		// Register the Lockvoker object in each lock's ticketQ.
+		lock.second = lock.first.register(lockvoker);
+	}
+	registered = true;
+}
+
+bool LockSet::tryAcquire(LockerAndInvoker &lockvoker)
+{
+	if (!registered) {
+		// Should never happen.
+		throw ...;
+	}
+	int nLocksAcquired=0,
+		nLocksInSet = lockset.size();
+	for (auto &lock: lockset.locks) {
+		if (!lock.first.tryAcquire(nLocksInSet)) {
+			break;
+		}
+
+		nLocksAcquired++;
+	}
+
+	if (nLocksAcquired == nLocksInSet) {
+		// Success
+		return true;
+	}
+
+	for (int i=0; i<nLocksAcquired; i++) {
+		// Backoff does different stuff from release();
+		locks[i].first.backoff(lockvoker);
+	}
+}
+
+LockSet::release()
+{
+	for (auto &lock: requiredLocks) {
+		lock.release();
+	}
+}
+```
+
+Now, the Qutex class is what we'll use for synchronization. It's just a
+combination of a SpinLock, a sh_ptr<LockerAndInvoker> and a std::list.
+
+```
+class SpinLock
+{
+	/* Modify to add methods acquire() and release() which busy-wait.
+	 */
+	void acquire();
+	void release();
+};
+
+class LockSet
+{
+	/* Modify the std::vector of SpinLock to instead be:
+	 *	std::vector<LockUsageDesc> locks;
+	 */
+	std::vector<LockUsageDesc> locks;
+}
+
+bool LockerAndInvoker::operator==(const LockerAndInvoker &other)
+{
+	/* Compare by the address of the continuation objects. Why?
+	 * Because there's no guarantee that the lockvoker object that was
+	 * passed in by the io_service invocation is the same object as that
+	 * which is in the qutexQs. Especially because we make_shared() a
+	 * copy when registerInQutexQueues()ing.
+	 *
+	 * Generally when we "wake" a lockvoker by enqueuing it, boost's

+			 * The reason why we do this rotation is to avoid a particular kind
+			 * of deadlock wherein a grid of async requests is perfectly
+			 * configured so as to guarantee that none of them can make any
+			 * forward progress unless they get reordered.
+			 *
+			 * Consider 2 different locks with 2 different items in them
+			 * each, both of which come from 2 particular requests:
+			 *	Qutex1: Lockvoker1, Lv2
+			 *	Qutex2: Lv2, Lv1
+			 *
+			 * Moreover, both of these lockvokers have requiredLocks.size()==2,
+			 * and the particular 2 locks that each one requires are indeed
+			 * Qutex1 and Qutex2.
+			 *
+			 * This particular setup basically means that in TL1's queue, Lv1
+			 * will wakeup since it's at the front of TL1. It'll successfully
+			 * acquire TL1 (since it's at the front), and then it'll try to
+			 * acquire TL2. But since Lv1 isn't in the top 50% of items in TL2's
+			 * queue, Lv1 will fail to acquire TL2.
+			 *
+			 * Then similarly, in TL2's queue, Lv2 will wakeup since it's at
+			 * the front. Again, it'll successfully acquire TL2 since it's at
+			 * the front of TL2's queue. But then it'll try to acquire TL1.
+			 * Since it's not in the top 50% of TL1's enqueued items, it'll fail
+			 * to acquire TL1.
+			 *
+			 * N.B: This type of perfectly ordered deadlock can occur in any
+			 * kind of NxN situation where ticketQ.size()==requiredLocks.size().
+			 * That could be 4x4, 5x5, 6x6, etc. It doesn't happen in 1x1
+			 * because a Lockvoker that only requires one lock will always just
+			 * succeed if it's at the front of its queue.
+			 *
+			 * This state of affairs is stable and will persist unless these
+			 * queues are reordered in some way. Hence: that's why we rotate the
+			 * items in a QutexQ after backing off of it. Backing off means
+			 * Not necessarily that the calling LockVoker failed to acquire
+			 * THIS PARTICULAR Qutex, but rather than it failed to acquire
+			 * ALL of its required locks.
+			 *
+			 * Hence, if we are backing out, we should also rotate the items
+			 * in the queue if the current front item is the failed acquirer.

+		 *	Lv3 release()s that common lock.

+		 *	Lv2 was not at the front of the qutexQ, so it does NOT awaken the

+		 *
+		 * Thus, Lv1 never gets awakened again. The end.

+# Spinqueueing: A new locking method that only blocks requests and not threads.
+
+The idea is that instead of using sleeplocks like mutexes, we instead only spin
+particular request objects by re-posting them to the queue.
+
+Particular requests may need a given shared resource. Instead of sleeping a
+whole thread while that particular request waits for the resource, we instead
+sleep the request itself by re-posting it into the thread's queue. This
+basically implements a kind of spinlock without busy-waiting. The underlying
+thread is never blocked unless it has no requests that can make forward
+progress.
+
+Forward progress through requests is only halted when an external resource is
+actually being waited on. Generally this will be an actual hardware event that
+is being waited on. No software bottlenecks will be slept on.
+
+All locks in the program are simple spinlocks, but the algorithm to spin on them
+is:

+
+### Mode/Stim/Affordance Parameter Values
+
+| Data Type | Mode Values | Description |
+|-----------|-------------|-------------|
+| Point Cloud Intensity | `pointCloudIntensity`, `pcloudIntensity`, `pCloudIntensity`, `pCloudI`, `pcloudI` | Light intensity/reflectivity data |
+| Point Cloud Coordinates | `pcloud`, `pCloud`, `pointCloud` | Spatial coordinate data |
+| Gyroscope | `gyro` | Angular velocity measurements |
+| Accelerometer | `accel` | Linear acceleration measurements |
+
+### Format Parameter Values (for point cloud modes)
+
+| Format | Description |
+|--------|-------------|
+| `xyz` | Standard Cartesian coordinates (X, Y, Z) |
+| `spherical` | Raw spherical coordinates (range, azimuth, elevation) |

+
+## Device Discovery and Connection
+
+The specification uses a retry-based connection strategy with two different approaches:
+
+### Connection Methods
+
+**1. Broadcast-Based Connection (connectToKnownDeviceReq)**
+- Uses device IP addresses discovered from broadcast advertisements
+- **smo-ip parameter**: Optional - if omitted, driver auto-detects the appropriate interface
+- **smo-subnet-nbits parameter**: Optional - used for validation if smo-ip is provided
+- **When to use**: When devices are actively broadcasting their presence
+
+**2. Heuristic Connection (connectByDeviceIdentifierReq)**
+- Generates device IP addresses from serial numbers using network prefix
+- **smo-ip parameter**: **Required** - needed to determine network prefix for IP generation
+- **smo-subnet-nbits parameter**: **Required** - needed to calculate valid device IP addresses
+- **When to use**: When devices are not broadcasting or for initial setup
+
+### Connection Strategy
+
+1. **Initial Check**: Check if device is already known from broadcasts
+2. **Direct Connect**: Attempt direct connection based on calculated IP address
+3. **Retry Wait**: If direct connect fails, wait for `retry-delay-ms` for broadcast messages
+4. **Final Check**: Check known devices again after retry delay
+5. **Report Result**: Success or failure based on final check
+
+## Data Formats
+
+### Point Cloud Coordinate Formats
+
+1. **XYZ Format**: Standard 3D Cartesian coordinates
+   - X, Y, Z in meters
+   - Standard coordinate system orientation
+
+2. **Spherical Format**: Raw spherical coordinates
+   - Range (distance) in meters
+   - Azimuth angle in degrees/radians
+   - Elevation angle in degrees/radians
+
+3. **Spherical-Cartesian Format**: Spherical coordinates converted to Cartesian
+   - Range, azimuth, elevation converted to X, Y, Z
+   - Maintains spherical measurement precision
+
+4. **Dual Formats**: Support for dual-coordinate systems
+   - Useful for devices with multiple measurement modes
+   - Provides redundancy and validation capabilities
+
+### Intensity Data
+
+- Reflectivity values typically in the range 0-255
+- Normalized intensity measurements
+- Calibrated for material reflectivity analysis
+
+### IMU Data
+
+- **Gyroscope**: Angular velocity measurements (rad/s)
+- **Accelerometer**: Linear acceleration measurements (m/s²)
+- Timestamped data synchronized with point cloud measurements
+
+## Error Handling
+
+The specification includes comprehensive error handling for:
+
+- Network connectivity issues
+- Device communication timeouts
+- Invalid coordinate format requests
+- IMU data stream interruptions
+- Device discovery failures
+- Connection retry timeouts

-# exported API, or moved to Autoconf or Automake where they belong.
-#
-# The trouble is, aclocal is a bit thick.  It'll see the old AC_DEFUN

-# We use AC_DEFUN over AU_DEFUN for compatibility with aclocal-1.6.
