-# TK-10896 — Claude vs Codex comparison (model=codex)
-
-Scope: independent read-only/dry-run comparison. No canonical DB writes and no
-new SKU allocation. The standing rule is authoritative: recover an already
-existing code from evidence, or re-scrape; never mint a sequential code.
-
-| Finding | Claude / ticket ledger | Codex comparison | Verdict |
-|---|---|---|---|
-| Original active-blank scope | 33,946, later 34,569 after Phase 1 accounting | Mac2 mirror currently reports 34,600 | Different snapshots; mirror is advisory, not canonical |
-| Safe existing-code self-copy | 18,502 scoped; 18,369 clean rows applied before the no-mint ruling | 25,623 mirror rows remain dry-run self-copy candidates after collision and provenance guards | Agreement on method; current count is mirror-only |
-| Collision/duplicate rows | 133 routed to TK-10649; examples include Novasuede and Arte | 9 currently surface on the mirror because most prior rows no longer meet blank-active scope | Agreement on route; no auto-fix |
-| Re-scrape need | 12,589 no-identifier rows; Carnegie 5,921 anchor | 8,962 mirror rows: 8,897 mint-residue plus 65 genuinely bare | Broad agreement after accounting for mirror residue |
-| Greenfield prefixes | Phase 4 allocated previously unused `DWAG/DWAX/DWCX/DWST/DWSC/DWDX/DWWG` prefixes, then Steve reverted the allocation | Codes in these prefixes on blank rows are blocked from self-copy and routed to `MINT_RESIDUE_RESCRAPE` | Codex accepts Claude's provenance evidence; this is required by no-mint |
-| Bucket-A prefixes | Existing prefixes such as `DWKN/DWTT/DWRW/DWJS/DWRO/DWCC` predated Phase 4, but some ranges were also minted and reverted | Prefix alone cannot distinguish native codes from mint residue; exact reverted-number ledger is still required | Partial/unresolved; do not claim blanket provenance |
-| Canonical authority | Kamatera owns `shopify_products` | Scanner run here used the Mac2 mirror only | Canonical totals remain unverified by this pass |
-
-## Codex conclusion
-
-Claude's phase ledger resolves the largest ambiguity in the initial Codex scan:
-the seven greenfield-prefix cohorts are reverted mint residue, not valid recovery
-candidates. The guarded dry run therefore reports:
-
-- 25,623 `recoverable_now_self_copy`
-- 8,962 `rescrape_program_TK10900`
-- 9 `dedup_gated_TK10649`
-- 6 `recoverable_now_staging_link`
-
-This comparison does not authorize applying any candidate. Canonical recovery
-must be re-counted on Kamatera and every write remains separately gated.
