String returns the class name, or "S?" for an unknown class.

Get returns the bytes at key, or ErrNotFound.

replace returns the input with all matches replaced by [REDACTED:<name>].

Compress returns the compressed bytes with ok=true on success. On any parse problem (malformed input, an unsupported shape) it returns (nil-or-input,

Handler returns the standalone HTTP handler: health, metrics, and the proxy catch-all, plus the separately authenticated framework optimization API.

Open opens (creating if needed) the SQLite database at path and migrates the schema. logger may be nil.

OpenMemory returns a fresh in-memory store.

Release the optional background refresh timer. Mirrors the Python `close()`.

Count returns a local token estimate for b.

New builds an engine with the default compressor registry. store backs CCR recovery and stats and may be nil — without it the engine still detects and

New constructs a standalone proxy Server.

Latch this client off. Every later `decide()` returns the caller's baseline.

Format renders a rollup as a stable, human-readable string.

Valid reports whether c is a registered class.

New assembles a standalone gateway server from a config and a telemetry sink.

ExtractCompressible returns only the request's cache-cold live-zone text segments and a reassemble fn that byte-splices replacements into the original

Open ignores path (there is no filesystem) and returns an in-memory store.

Decide what to run for ``task_family``. Synchronous, local, total. Performs no network I/O and never raises — a garbage context, a broken

all loads every memory.

Run a block inside a trace. The trace allocates a ``trace_id`` (32 lowercase hex) and a root ``span_id`` (16 lowercase hex) with the

Len reports how many objects are stored (test helper for ZDR assertions).

Load reads caveman.yaml from path, applying defaults. A missing file yields the default config (record mode on 127.0.0.1:8787) rather than an error: a

ParseUsageBytes extracts token usage from a complete provider response body, whether a single JSON document (non-stream) or an SSE / newline-delimited

Native adapters use this when their installed framework is untested. * No content or network request is sent. Strict mode remains explicit.

Put writes body at key, overwriting any existing object.

Remember stores text durably and returns it with a content-addressed id. Remembering identical current text twice is idempotent (same id, stored once)

SanitizeAndMapHeaders maps the inbound headers to the upstream header set and applies any provider auth/signing. upstream is the ALREADY-RESOLVED forw
