@@ -49,6 +49,7 @@ and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0
 - **Tokenizer**: `time.Now`/`time.Since` are now read only when metrics are enabled (previously twice per tokenization even when disabled). If metrics are toggled on mid-call the call is not recorded. No API or token-output change [W1-02].
 - **Tokenizer**: keyword and compound-keyword-start lookup now uses a single fused-hash open-addressed table (one FNV-1a hash computed while upper-casing, one probe) instead of two Go map lookups per identifier. The table is filled in a fixed order (hot keywords first, then sorted) so its probe layout is deterministic across processes. No behaviour change; token output is identical [W2-01].
 - **Tokenizer**: token Start/End locations are now computed from a cached current-line window (a range check and a subtraction) instead of two calls to the non-inlinable position lookup per token; out-of-window offsets take the existing lookup. Token positions are identical, including after a UTF-8 BOM and across pooled-tokenizer reuse (guarded by an oracle test). [W2-02]
+- **Tokenizer**: `@param` and SQL Server `@@var` token values are now slices of the input instead of `"@"+name` concatenations, removing one string allocation per parameter (SQL Server real-world allocs/op -90% to -100%, MariaDB/MySQL/Snowflake -50% to -67% on the large cells). Names that `readIdentifier` treats specially (`U&` escapes, a single letter before a quote, compound-keyword starts such as `@group by`, non-ASCII names) keep the previous path, so token types, values and spans are identical (pinned by a golden over 9 dialects). [W2-03]
 - **Pools**: the tokenizer, parser and AST pools now count Get/Put through precreated, cache-line padded atomic counters (`internal/poolstats`) instead of an RWMutex-guarded map keyed by pool name, removing a lock, map lookup and string hash from every pool operation. `metrics.GetPoolStats` and `metrics.ResetPoolStats` behave exactly as before; named custom pools keep the map path. [W1-01]
 - **Parser**: token preprocessing now takes a type-gated fast path. Only identifier, keyword, aggregate and compound tokens take the normalisation path; every other token is appended with a single copy. Output is identical (guarded by an old-versus-new differential test); no API or behaviour change.
 - **Parser**: the parser's current token is now a pointer into its token slice (with a per-parser zero EOF sentinel) instead of a 72-byte copy made on every `advance`, and `peekToken` returns a pointer, which removes most GC write-barrier work and struct copying from the parse loop. Parse results, errors and positions are byte-identical (behaviour goldens plus a recovery-path differential); no API change. A zero-value `&Parser{}` keeps working. [W3-02]
