Action required

1. Ctest artifact committed 🐞 Bug ⛯ Reliability

Testing/Temporary/CTestCostData.txt appears to be a generated CTest temporary artifact committed
into source control. This can cause persistent dirty working trees and can interfere with in-source
build/testing workflows or tooling that expects Testing/ to be build output only.
Agent Prompt 
## Issue description
A build/test artifact (`Testing/Temporary/CTestCostData.txt`) is committed into source control. This directory/file is typically generated by CTest and should not live in the repo.

## Issue Context
The repository’s testing docs recommend out-of-source builds (`-B build` then `cd build`), implying `Testing/` should be generated under the build directory, not tracked at repo root.

## Fix Focus Areas
- Testing/Temporary/CTestCostData.txt[1-1]
- .gitignore[120-220]

## Expected change
- Delete `Testing/Temporary/CTestCostData.txt` from the repository.
- Add a `.gitignore` rule to ignore `Testing/` (or at minimum `Testing/Temporary/` and `Testing/**/*.txt`) so CTest-generated outputs can’t be accidentally committed again.

Testing/Temporary/CTestCostData.txt is a CTest-generated artifact (normally created in the build/test tree). It shouldn’t be committed; please remove it from the repo and add Testing/ (or at least Testing/Temporary/) to .gitignore to avoid future churn.

Suggested change

# This file was previously a CTest-generated artifact and should not contain test output.
# It is kept empty/intentionally minimal; consider deleting it from version control and
# adding `Testing/` or `Testing/Temporary/` to .gitignore.

- **Plan**: Implement FIR-based EQs with FFT convolution for zero phase distortion options.

### Dynamic Oversampling

- **Plan**: Add toggleable per-plugin or global dynamic oversampling (2x, 4x, 8x, 16x) using polyphase filter banks to minimize aliasing with non-linear processing (like saturation or heavy compression), specifically when rendering offline.
- **Benefit**: Retain real-time low-latency performance when producing, but get mathematically pure results when exporting.

### Analog Drift Modeling

- **Plan**: Modulate internal parameters of classic analog modeled plugins (oscillators, filters, envelopes) with very slow, band-limited noise to simulate component age and temperature fluctuations.
- **Benefit**: Adds subtle warmth and unpredictable "life" to static digital signals.

### Spectral Anti-Aliasing

- **Plan**: Detect high-frequency harmonic content that would exceed Nyquist prior to applying heavy distortion. Instead of basic oversampling, apply adaptive band-limiting to only the problematic upper harmonics.
- **Benefit**: Less CPU intensive than blanket oversampling while still preventing the harsh metallic artifacts of aliasing.

## 4. Fixes & Cleanups

### Real-Time Safety

- **Violation**: `SamplerPlugin` uses `std::unique_lock` in `process()`.
- **Fix**: Replaced with `std::atomic<std::shared_ptr>` + Deferred Reclamation (GC).
- **Violation**: `EffectChain` deleted operators (False Positive in audit, but good to know).
- **Violation**: Audit script flags deleted operators like `EffectChain(const EffectChain&) = delete;`.
- **Fix**: Appended `// ALLOW_REALTIME_DELETE` to these statements and updated the `scripts/audit_codebase.py` to ignore them.
- **Leak**: `AestraCore/include/AestraThreading.h` and some `AestraAudio` headers include `<windows.h>`.
- **Fix**: Explicitly marked necessary platform includes with `// ALLOW_PLATFORM_INCLUDE` to pass `scripts/check_platform_leaks.py`.

ALLOW_REALTIME_DELETE currently suppresses any forbidden keyword match on that line (e.g., it would also hide new/malloc/locks if someone adds the comment). If the intent is only to silence false positives from C++ “deleted functions”, restrict the exception to the delete keyword pattern (or only when matching = ... delete), and consider renaming the marker if it’s meant to be a general audit suppression.

Suggested change
# Ignore ALLOW_REALTIME_DELETE and deleted functions
if "ALLOW_REALTIME_DELETE" in stripped or "= delete" in stripped:
# Ignore ALLOW_REALTIME_DELETE and deleted functions only for the 'delete' keyword
if pattern == r"\bdelete\b" and ("ALLOW_REALTIME_DELETE" in stripped or "= delete" in stripped):

The check for deleted functions is a brittle substring match ("= delete"). This will miss valid formatting like =delete or = delete and can still leave the audit noisy. Prefer a small regex like =\s*delete\b (and ideally strip inline/multi-line comments before scanning) to make the heuristic more reliable.
