- A clear understanding of the codebase
- Alignment with product direction
- Thoughtful reasoning behind changes
- Evidence of real-world usage or hands-on experience with the problem
-
-If these expectations are not met, we would prefer to implement the changes ourselves rather than spend time reviewing low-effort submissions.

-### Controlling Ripgrep search and fzf search simultaneously
-
-`search` and `transform-search` action allow you to trigger an fzf search with
-an arbitrary query string. This frees fzf from strictly following the prompt
-input, enabling custom search syntax.
-
-In the example below, `transform` action is used to conditionally trigger
-`reload` for ripgrep, followed by `search` for fzf. The first word of the
-query initiates the Ripgrep process to generate the initial results, while the
-remainder of the query is passed to fzf for secondary filtering.

-export TEMP=$(mktemp -u)

-# SIMD byte search: `indexByteTwo` / `lastIndexByteTwo`
-
-## What these functions do
-
-`indexByteTwo(s []byte, b1, b2 byte) int` -- returns the index of the
-**first** occurrence of `b1` or `b2` in `s`, or `-1`.
-
-`lastIndexByteTwo(s []byte, b1, b2 byte) int` -- returns the index of the
-**last** occurrence of `b1` or `b2` in `s`, or `-1`.
-
-They are used by the fuzzy matching algorithm (`algo.go`) to skip ahead
-during case-insensitive search. Instead of calling `bytes.IndexByte` twice
-(once for lowercase, once for uppercase), a single SIMD pass finds both at
-once.

-## How the SIMD implementations work
-
-**ARM64 (NEON):**
- Broadcasts both needle bytes into NEON registers (`VMOV`).
- Processes 32-byte aligned chunks. For each chunk, compares all bytes
-  against both needles (`VCMEQ`), ORs the results (`VORR`), and builds a
-  64-bit syndrome with 2 bits per byte.
- `indexByteTwo` uses `RBIT` + `CLZ` to find the lowest set bit (first match).
- `lastIndexByteTwo` scans backward and uses `CLZ` on the raw syndrome to
-  find the highest set bit (last match).
- Handles alignment and partial first/last blocks with bit masking.
- Adapted from Go's `internal/bytealg/indexbyte_arm64.s`.
-
-**AMD64 (AVX2 with SSE2 fallback):**
- At init time, `cpuHasAVX2()` checks CPUID + XGETBV for AVX2 and OS YMM
-  support. The result is cached in `_useAVX2`.
- **AVX2 path** (inputs >= 32 bytes, when available):
-  - Broadcasts both needles via `VPBROADCASTB`.
-  - Processes 32-byte blocks: `VPCMPEQB` against both needles, `VPOR`, then
-    `VPMOVMSKB` to get a 32-bit mask.
-  - 5 instructions per loop iteration (vs 7 for SSE2) at 2x the throughput.
-  - `VZEROUPPER` before every return to avoid SSE/AVX transition penalties.
- **SSE2 fallback** (inputs < 32 bytes, or CPUs without AVX2):
-  - Broadcasts via `PUNPCKLBW` + `PSHUFL`.
-  - Processes 16-byte blocks: `PCMPEQB`, `POR`, `PMOVMSKB`.
-  - Small inputs (<16 bytes) are handled with page-boundary-safe loads.
- Both paths use `BSFL` (forward) / `BSRL` (reverse) for bit scanning.
- Adapted from Go's `internal/bytealg/indexbyte_amd64.s`.
-
-**Fallback (other platforms):**
- `indexByteTwo` uses two `bytes.IndexByte` calls with scope-limiting
-  (search `b1` first, then limit the `b2` search to `s[:i1]`).
- `lastIndexByteTwo` uses a simple backward for loop.
-
-## Running tests
-
-```bash
-# Unit + exhaustive tests
-go test ./src/algo/ -run 'TestIndexByteTwo|TestLastIndexByteTwo' -v
-
-# Fuzz tests (run for 10 seconds each)
-go test ./src/algo/ -run '^$' -fuzz FuzzIndexByteTwo -fuzztime 10s
-go test ./src/algo/ -run '^$' -fuzz FuzzLastIndexByteTwo -fuzztime 10s
-
-# Cross-architecture: test amd64 on an arm64 Mac (via Rosetta)
-GOARCH=amd64 go test ./src/algo/ -run 'TestIndexByteTwo|TestLastIndexByteTwo' -v
-GOARCH=amd64 go test ./src/algo/ -run '^$' -fuzz FuzzIndexByteTwo -fuzztime 10s
-GOARCH=amd64 go test ./src/algo/ -run '^$' -fuzz FuzzLastIndexByteTwo -fuzztime 10s
-```
-
-## Running micro-benchmarks
-
-```bash
-# All indexByteTwo / lastIndexByteTwo benchmarks
-go test ./src/algo/ -bench 'IndexByteTwo' -benchmem
-
-# Specific size
-go test ./src/algo/ -bench 'IndexByteTwo_1000'
-```
-
-Each benchmark compares the SIMD `asm` implementation against reference
-implementations (`2xIndexByte` using `bytes.IndexByte`, and a simple `loop`).
-
-## Correctness verification
-
-The assembly is verified by three layers of testing:
-
-1. **Table-driven tests** -- known inputs with expected outputs.
-2. **Exhaustive tests** -- all lengths 0–256, every match position, no-match
-   cases, and both-bytes-present cases, compared against a simple loop
-   reference.
-3. **Fuzz tests** -- randomized inputs via `testing.F`, compared against the
-   same loop reference.
