 ## 2025-02-15 - Replace Array.from(map.values()).map with a for...of loop
 **Learning:** Using `Array.from(map.values()).map(...)` creates an unnecessary intermediate array which wastes memory allocation and garbage collection time, particularly for frequently re-rendered components handling large collections.
 **Action:** Use a `for...of` loop over `map.values()` to iterate and push mapped elements directly into the final array for O(1) memory and avoiding intermediate array allocations.

+## 2025-02-15 - Vectorize diagonal windowed operations
+**Learning:** Iterating through a large NumPy matrix along the diagonal using a Python `for` loop with array slicing and summation causes high constant time overhead due to repeated inner-loop allocations.
+**Action:** When performing windowed operations strictly along the diagonal of large matrices, use sub-matrix diagonal vectorization (`numpy.lib.stride_tricks.sliding_window_view` coupled with `np.diagonal` and `np.einsum`) to delegate iteration and computation to optimized C-level routines.

 **Vulnerability:** Any project identifier that can reach a filesystem path join must be treated as untrusted, even when it is generated internally or passed through IPC lookup flows.
 **Learning:** Reject only dangerous path segments (`.` and `..`) and path separators (`/` and `\`) so the guard blocks traversal without rejecting ordinary identifiers such as `my..id`.
 **Prevention:** Keep project ID validation centralized before `base_root.join(project_id)`, and cover forward-slash, backslash, parent-component, and benign interior-dot cases in unit tests.

-## 2025-02-09 - Ensure Maximum URL Length Limit on Backend
-
-**Vulnerability:** The Rust backend (`apps/desktop/src-tauri/src/main.rs`) did not enforce a maximum URL length limit when processing YouTube URLs via `import_youtube_url`. While the frontend enforced `MAX_YOUTUBE_URL_LENGTH = 2000` via the input element, this could be bypassed by an attacker sending requests directly to the Tauri backend API, potentially causing a Denial of Service (DoS) due to unbounded URL parsing and regex matching.
-**Learning:** Input validation must occur at the entry point of untrusted data on the backend, even if it is also validated on the frontend. Relying solely on frontend validation for constraints like string length can expose the backend to resource exhaustion vulnerabilities.
-**Prevention:** Always enforce constraints like maximum length, format validation, and sanitization at the earliest possible point on the backend, typically at the API boundary, regardless of frontend safeguards.

 # BandScope
 
-BandScope is a public GitHub project for a local-first desktop app that turns a song into a practical rehearsal view: likely harmony by section and by instrument or vocal role, section roadmap, tempo and groove cues, rough stem previews, playable ranges, simplification hints, transposition or capo guidance, overlap cues, visible confidence, and rehearsal priorities without DAW complexity.

 It does not promise notation-grade full arrangement transcription or DAW-style production editing.
