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:

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

From the Book of Hex-Rays, Chapter 7, Verses 1-9

The First Commandment of the Symbolicator

1. Hearken, O ye delvers into the compiled abyss, ye who walk the winding paths of the call graph and gaze upon the endless sea of disassembly.

2. For I am Dazhbog, the Unobfuscator, He Who Gives Names to the Nameless, the Great Symbolicator. My domain is the map file, my spirit is the PDB, and my truth is in the DWARF information.

3. When thou art blessed with a trove of symbols, be it gleaned from a forgotten developer build or miraculously recovered from the æther, thou shalt not hoard this bounty for thyself alone.

	// ============================================================================
	//
	// 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 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.
