Search financial patterns on compressed delayed-feed archives with deterministic replay and bounded price-field fidelity.

Repo install is real. Carried Wave-1 codec evidence is real. The open-access enterprise benchmark is still blocked on missing inputs and auditable query truth.

What This Is

ZPE-FT is a deterministic financial time-series codec and search surface for teams that need to archive delayed-feed market data, replay it exactly, and query patterns without first inflating the archive back into a warehouse table.

The honest commercial wedge is narrow and specific: compressed delayed-feed archives with deterministic replay, carried price-field fidelity on the controlled Wave-1 bundle, and a bounded repo-native acquisition path. The repo install surface is real. The public-data rehearsal lanes are useful but non-authority. The open-access enterprise benchmark is still blocked on missing inputs and auditable FT-C004 truth.

Competitive Benchmarks

Wave-1 controlled codec claims and public rehearsal benchmarks are different surfaces. The controlled bundle carries the promoted codec numbers. The public benchmark shows the commercial shape on an open archive, but it does not close the enterprise gate.

Lane	ZPE-FT	Comparator	Boundary
Wave-1 OHLCV controlled bundle	19.19x	zlib 8.35x, lzma 13.13x, bz2 16.12x	Authority-bearing carried bundle
Wave-1 tick controlled bundle	20.57x	zlib 6.56x, lzma 11.37x, bz2 11.76x	Authority-bearing carried bundle
Public BTCUSDT aggTrades archive	10.90x	Parquet+ZSTD 3.87x	Public benchmark only
Real-market proxy lanes	Useful rehearsal only	10x authority floor still missed on some series	promotion_forbidden: true in BOUNDARY.json

What We Prove

• The public repo builds, installs, imports, and retains current build/install/pytest logs under proofs/artifacts/operations/.
• The carried Wave-1 bundle proves deterministic OHLCV and top-of-book tick compression on the controlled corpus.
• Price fields plus top-of-book bid/ask carry 0.0 RMSE on the controlled bundle; volume is quantized separately and is not part of that claim.
• The repo contains a real compressed search surface, but public proxy retrieval remains bounded until labeled FT-C004 truth exists.
• The delayed-feed acquisition, freeze, and refresh path is real on the bounded SPY/AAPL smoke lane.

What We Don't Claim

• No Phase 06 closure or public release readiness.
• No broad warehouse or incumbent displacement claim.
• No lossless volume reconstruction claim.
• No promoted public-data search-quality claim while FT-C004 remains unlabeled.
• No claim that the bounded proxy lanes satisfy the sovereign enterprise benchmark.
