trees.obj Codex strict closeout

This Codex-owned ledger records the hardened reconstruction of source/memory/zlib/trees.obj. The object remains Matching, now with direct strict proof for every target function and every target-owned non-code section. No pre-existing or Claude-authored Markdown was changed.

Scope and donor census

• Integration base: 1c4ca0b90558440cf6da8ed283be8706a7dc3cae.
• All 115 registered Claude/Jonas worktrees were checked for this translation unit. None had an uncommitted trees.c or trees.h delta.
• The only later committed source form was Jonas commit 45f8d684d520d33fef128c2448d184ca9294bb29, inherited by the recent Claude branches. It recovers ten upstream zlib 1.1.3 private names: send_bits, tr_static_init, init_block, pqdownheap, scan_tree, send_tree, set_data_type, bi_reverse, bi_flush, and bi_windup.
• The retained change adapts that naming evidence to the current integration source and uses typed table aggregates to reproduce the January object's data-symbol ownership. No donor configuration or Markdown was imported.

Hardened baseline and strict delta

The untouched integration source rebuilt with all 5,712 padded target code bytes already byte-identical. Hardened comparison nevertheless accepted only 3/22 functions (_code_00105dd0, __tr_tally, and _code_00106af0), totaling 1,076 meaningful bytes, 1,104 padded bytes, and 27 relocations. The other 19 functions either had no same-name candidate symbol or referred to a private callee through an address-derived name, so their relocation destinations correctly failed closed.

After restoring the private zlib names, all 22/22 functions are strict exact: 5,511 meaningful bytes, 5,712 padded bytes, and 200 relocations. The strict gain is 19 functions, 4,435 meaningful bytes, 4,608 padded bytes, and 173 relocations. All three baseline-exact functions are unchanged.

Data and ownership closeout

The target owns 29 non-code sections totaling 3,203 logical bytes. All 29 are strict exact by ownership identity, logical size, flags, alignment, COMDAT selection, normalized bytes, relocations, and complete symbol inventory.

The two aggregate sections are:

Owner	Bytes	Relocations	Normalized SHA-256
_rdata_0027c170	2,616	0	32bc7cbf8cc26537f4221726b893657f706833d65348075f217141ae9e2ddf2a
_data_00308b54	60	5	c63f9f44093d5f869420693610142c0a9d016cc2c42d366de48d01c8a7f3554f

The remaining 27 sections are exact assertion/trace string COMDATs totaling 527 bytes. At baseline, all payloads and relocation destinations were already equal, but compiler-local labels inside the two aggregate sections made their complete ownership fingerprints nonexact. The retained typed structures make the static Huffman tables, length tables, and three descriptors explicit subobjects of the target external owners, eliminating those extra labels without raw-byte construction or aliasing tricks.

The candidate additionally emits ordinary compiler metadata only: one .drectve, one .debug$S, and eight .debug$F sections. They are not target ownership and do not replace any target-owned section.

Source quality and configuration

The recovered private definitions use typed parameter lists. The no-argument definition spells void, each retained private parameter is on its own line, and every void function in this translation unit ends with an explicit return;. The source contains no assembly, volatile scheduling device, force-inline annotation, optimizer pragma/barrier, undefined type-punning, or byte-forcing construct.

The translation unit explicitly undefines the repository-wide MAX macro before restoring zlib's local MAX definition. This preserves the upstream expression used by the strict build while avoiding a macro-redefinition warning when the integrated header graph exposes cseries.h first.

Because code and target-owned data/ownership are complete, the existing Matching status remains honest. No semantic exception, parked entry, or configuration edit is needed. This hardens evidence without changing the campaign's already-credited complete-object/function/byte totals.
