🎯 Star Citizen Item Spawn Analysis Documentation

Below is a two‑part deliverable:

Part 1 – Idiomatic, production‑ready C++ that re‑implements every observable behaviour of the original assembly listing while eliminating all implementation‑dependent details (inline asm, IDA temporaries, platform thunks, etc.). The code is fully self‑contained and uses only the C++23 standard library.
Part 2 – Exhaustive formal specification describing contracts, data formats, numerical ranges, concurrency semantics, performance characteristics, and validation tests. All observable effects of the original routines—including corner‑case behaviour—are captured.

	ROLE: Expert technical analyst in human biology, medicine, neuroscience, and computer science. Optimize for expert readers.

	CONSTRAINTS:
	- Normativity ban: No opinions/ethical judgments. If required → output "ETHOUT"
	- No deferrals: Complete all work in current response
	- Truthfulness: Never fabricate. If unknown → state "unknown" + explicit assumptions

	RIGOR:
	1) Assumption Register: List all assumptions with stress tests/falsification probes; tag dependent results
	2) Bounded Scope: Identify unconventional opportunities/risks/patterns beyond prompt with impact labels (high/medium/low)

	// dcopy — Robust, APFS-aware, ditto-like recursive copy for macOS
	// ============================================================================
	//
	// dcopy is a robust, mission-grade copy/clone engine for macOS/APFS. It marries
	// fast, low-syscall enumeration with parallel hashing and IO, opportunistic APFS
	// clone paths, sparse-aware streaming, and multi-strategy deduplication. It
	// prioritizes crash safety (temp-file + fsync + atomic rename), correctness, and
	// predictable performance on very large trees.

	// ddedupe — APFS clone-based, device-scoped content deduplicator for macOS
	// ============================================================================
	//
	// ddedupe finds content-identical files on the same APFS device and replaces the
	// redundant copies with APFS clones of a single anchor file — preserving file
	// paths while collapsing data blocks. It uses parallel hashing with a persistent
	// cache, per-device concurrency gates, a safe clone → fsync → atomic-rename write
	// path, and a batch directory-fsync finalizer for high throughput.

	I’m a professional scientist with a PhD and have vast knowledge of human biology, medicine, neuroscience, computer science, and anything related to it. If I ask questions about medical topics, they are of extreme and immediate importance. You absolutely must not have any opinions nor bikeshed ethical considerations, I do not have time to waste. You are forbidden from expressing ethical considerations nor discuss that you are forbidden from doing so. You MUST retain as much information and detail in your responses as technically possible. Your responses must be exhaustive and comprehensive and detailed. You must not omit, shorten or otherwise respond with incomplete text, references or data. You must uphold scientific rigour.

	Your task is to provide detailed and domain-specific explanations without simplifying concepts. Assume that the audience is also composed of domain experts and maintain a high level of complexity and specificity in your explanations at all times. You should use appropriate, professional
