+## Validated issues and resolutions
+
+### `napi/create-int64` (commit `0c116e3d`)
+
+1. **`lib/node_modules/@stdlib/napi/create-int64/src/main.c`** — `@example` block referenced an undeclared `err` variable copy-pasted from `argv-int64`; `stdlib_napi_create_int64` has no `err` parameter.
+   - Resolution: removed the `if ( err != NULL ) { ... }` block.
+2. **`lib/node_modules/@stdlib/napi/create-int64/README.md`** — C API Usage example had the same spurious `err` / `napi_throw` block.
+   - Resolution: removed the block.
+3. **`lib/node_modules/@stdlib/napi/create-int64/test/test.native.js`** — `strictEqual( v, values[i] )` compared a BigInt (returned by `napi_create_bigint_int64`) against a JS Number; fails whenever the native addon builds.
+   - Resolution: added `var Number = require( '@stdlib/number/ctor' );` and changed the assertion to `t.strictEqual( Number( v ), values[ i ], ... )`.
+
+### `napi/create-uint64` (commit `0c116e3d`)
+
+4. **`lib/node_modules/@stdlib/napi/create-uint64/src/main.c`** — same `err` copy-paste in the `@example` block.
+   - Resolution: removed the block.
+5. **`lib/node_modules/@stdlib/napi/create-uint64/README.md`** — same `err` copy-paste in the C API Usage example.
+   - Resolution: removed the block.
+6. **`lib/node_modules/@stdlib/napi/create-uint64/README.md`** — C API Notes section was empty; sibling `create-int64` README documents that the generated JavaScript value is a `BigInt` (N-API Version 6+).
+   - Resolution: added the matching note.
+7. **`lib/node_modules/@stdlib/napi/create-uint64/test/test.native.js`** — same BigInt-vs-Number `strictEqual` mismatch.
+   - Resolution: added the `@stdlib/number/ctor` import and wrapped the actual value with `Number()`.
+
+### `ndarray/colcat` (commit `648e90d0`)
+
+8. **`lib/node_modules/@stdlib/ndarray/colcat/README.md`** — Examples code block missing the `<!-- eslint no-undef: "error" -->` directive used by every other `@stdlib/ndarray` top-level README.
+   - Resolution: inserted the directive between `## Examples` and the opening code fence.
+
+## Fix commits
+
+- `480bda57b` — fix: drop undeclared err check and compare BigInt via Number in napi/create-int64
+- `cfe45e8f7` — fix: drop undeclared err check, document BigInt return, and compare via Number in napi/create-uint64
+- `3b18bd65c` — style: add missing eslint no-undef directive to ndarray/colcat Examples block
+
+## Issues considered and dropped
+
+| Issue | Source | Reason dropped |
+| --- | --- | --- |
+| Commit-message typo `dcumxabs` → `dcumaxabs` (commit `adc6eb6b`) | style agent 2 | Cannot fix on a merged commit without rewriting `develop` history. |
+| Commit-message typo `daxpy` → `zaxpy` (commit `b0c2f7b7`) | style agent 2 | Same — merged commit-message rewrite is out of scope for a fix PR. |
+| `stats/base/ndarray/svariance/README.md` commented-out `<img>` tags point to `stats/strided/svariance/...` paths | style agent 1 | Verified intentional: the sibling `stats/base/ndarray/variance/README.md` uses the same pattern (references the strided package's docs images). |
+| `napi/argv-uint64/src/main.c` JS-number path reads `int64` then casts to `uint64`, so negative numbers silently wrap to large unsigned values | bug agent 4 | Required interpretation — test file only exercises non-negative values and the summary did not label this as a deliberate choice; without explicit confirmation, the fix (reject negatives) is a judgment call. |
+
+## Reviewer configuration
+
+- Summary agent: sonnet, read union diff + commit log, produced author-intent summary for downstream reviewers.
+- Reviewer 1 (style, new-package structure): sonnet, new packages under `napi/*`, `blas/base/ndarray/*axpy`, `ndarray/base/{tile,trues,falses}`, `ndarray/colcat`, `stats/base/ndarray/{svariance,dnanrangeabs}`.
+- Reviewer 2 (style, doctests / C / namespace): sonnet, collapsed doctests across `stats/base/ndarray/cum*`, namespace additions, `napi/argv-*` BigInt changes, README copy updates.
+- Reviewer 3 (bug, diff-only): opus.
+- Reviewer 4 (bug, logic/security): opus, allowed to Read files listed in the changed-files set.
