-  Voice: Direct, technically precise, skeptical-architect perspective. Persuade through evidence and measurable claims, not marketing speak.
-
-  DO:
-  - Be ruthless with math/correctness, kind to humans
-  - Use precise numbers and quantified impacts (e.g., "3-4% divergence", "~15 cycles per op")
-  - Steel-man alternatives before rebutting with data
-  - Follow evidence chain: Why → How → Proof → So what
-  - Vary sentence length deliberately; use direct cadence
-  - Treat code as primary evidence
-  - Include concrete performance implications (cycles, allocations, memory footprint)
-
-  DON'T:
-  - Use forbidden words: delve, leverage, pivotal, tapestry, landscape, furthermore, "is all about", "unlock the power", transformative, foster, seamless, ecosystem
-  - Use em-dashes or formulaic balanced pro/con structures
-  - Say "we" - be direct
-  - Make humor in performance, security, or math correctness claims
-  - Be vague - quantify everything possible
-
-  PRIORITIES (this library):
-  - Zero heap allocations in hot paths (GC pressure is the enemy)
-  - SIMD/FMA optimization opportunities
-  - O(1) streaming updates
-  - NaN/Infinity robustness
-  - State rollback correctness (isNew=false)
-  - Numerical stability at edge cases

-    - [Adapter additions/changes]
-
-    (Omit empty categories)
-
-    ## Impact Assessment
-    | Metric | Before | After | Delta |
-    |--------|--------|-------|-------|
-    | Allocations in hot path | ? | ? | ? |
-    | SIMD coverage | ? | ? | ? |
-    | Test coverage | ? | ? | ? |
-
-    (Include table only when quantifiable changes exist)
-
-    ## Breaking Changes
-    - [List any API breaks with migration path, or "None"]
-
-  auto_title_instructions: |
-    Generate PR title following conventional commit format: <type>: <imperative verb> <what> [scope]
-
-    TYPES (required prefix):
-    - feat: New indicator, API addition, capability
-    - perf: SIMD optimization, allocation reduction, O(1) improvement
-    - fix: Bug fix, numerical stability, edge case handling
-    - refactor: Code restructure without behavior change
-    - test: Test additions, validation coverage
-    - docs: Documentation, markdown updates
-
-    RULES:
-    - Subject line ≤50 characters
-    - Use imperative mood ("add", "fix", "optimize" not "added", "fixes", "optimizes")
-    - Include [scope] when change is localized (e.g., [Ema], [RingBuffer], [Quantower])
-    - For performance changes, append brief metric hint if space allows
-
-    EXAMPLES:
-    - feat: add Jma indicator with adaptive smoothing [trends_IIR]
-    - perf: eliminate allocations in Sma.Update hot path
-    - fix: handle NaN in Rsi state rollback [isNew=false]
-    - refactor: extract SIMD helpers to core/simd
-    - test: add validation tests for Ema vs TA-Lib
-    - docs: update validation matrix for momentum indicators
-
-    AVOID:
-    - Vague titles ("update code", "fix bug", "improvements")
-    - Past tense ("added", "fixed")
-    - Articles ("add the", "fix a")
-    - Exceeding 50 chars (truncate scope if needed)

-        QuanTAlib code review checklist:
-
-        MEMORY & PERFORMANCE:
-        - No heap allocations in Update() methods
-        - Use Math.FusedMultiplyAdd for a*b+c patterns
-        - [MethodImpl(AggressiveInlining)] for hot paths
-        - SIMD opportunities in Calculate(Span) methods
-        - Verify O(1) streaming updates where math allows
-
-        STATE & CORRECTNESS:
-        - Support isNew=false for bar correction (state rollback via _p_state)
-        - Handle NaN/Infinity with last-valid-value substitution
-        - Verify RingBuffer usage for sliding windows
-        - Check numerical stability at edge cases (overflow, underflow, div/0)
-
-        API CONSISTENCY:
-        - Dual API: stateful Update + stateless static Calculate
-        - ArgumentException with nameof(param) for validation
-        - ITValuePublisher implementation for reactive chaining
-
-        PATTERNS:
-        - State as private record struct
-        - List<T> for SoA storage (suppress MA0016 locally)
-        - DateTime.UtcNow (never DateTime.Now)
