- @capakraken/* → @nexus/* across 12 packages (root + 11 workspaces),
1551 import lines migrated via codemod
- User-visible brand strings renamed (emails, page titles, PWA
manifest, mobile header, MFA backup-codes header, tooltips, signin
page, invite page, weekly digest, install prompt)
- TOTP issuer "CapaKraken" → "Nexus" (existing secrets still valid;
re-enrollment relabels them in users' authenticator apps)
- Function rename: assertCapaKrakenDbTarget → assertNexusDbTarget
- LocalStorage migration shim in apps/web/src/app/layout.tsx copies
capakraken_* → nexus_* on first load (guarded by nexus_migrated_v1
sentinel; runs once per browser, then never again)
- Service-worker cache name capakraken-v2 → nexus-v2 with one-time
caches.delete('capakraken-v2') from the same shim
- Email-domain fixtures @capakraken.{dev,app} → @nexus.{dev,app} in
seed data, e2e specs, SMTP default fallback
- Dockerfile.dev / Dockerfile.prod / all .github/workflows/*.yml
pnpm --filter @capakraken/* → @nexus/*
- README, CLAUDE.md, LEARNINGS.md, all docs/*.md, .env.example,
tooling/deploy/.env.production.example brand sweep
Phase 1 deliberately leaves untouched (handled in Phase 3 cutover):
- PostgreSQL DB name "capakraken" and POSTGRES_USER "capakraken"
- Volume names capakraken_pgdata etc.
- Compose project name "capakraken" / "capakraken-prod"
- db-target-guard default expectedDatabase
- env-var CAPAKRAKEN_EXPECTED_DB_NAME
- Container DNS names in docker-compose.ci.yml
Quality gates green: pnpm typecheck (7/7), pnpm test:unit (7/7),
pnpm lint (0 errors), check:exports/imports/architecture all pass.

# Import Hardening
|
|
|
|
**Date:** 2026-03-30
|
|
**Purpose:** Define the safe parser boundary for untrusted spreadsheet imports.
|
|
|
|
## Decision
|
|
|
|
- Untrusted workbook imports no longer accept legacy `.xls`.
|
|
- Server-side dispo imports accept only `.xlsx` files.
|
|
- Browser-side ad hoc imports accept `.xlsx` and `.csv`.
|
|
- Workbook import and export generation now use `exceljs` instead of direct runtime `xlsx` usage.
|
|
|
|
## Server Boundary
|
|
|
|
The dispo-import reader in [read-workbook.ts](/home/hartmut/Documents/Copilot/nexus/packages/application/src/use-cases/dispo-import/read-workbook.ts) now enforces:
|
|
|
|
- normalized filesystem paths before reading
|
|
- regular-file checks
|
|
- non-empty file checks
|
|
- a hard size limit of `15 MiB`
|
|
- a worksheet row limit of `10,000`
|
|
- a worksheet column limit of `256`
|
|
- `.xlsx`-only parsing through `exceljs` behind a hardened server-side parser boundary
|
|
|
|
The API entry points in [dispo.ts](/home/hartmut/Documents/Copilot/nexus/packages/api/src/router/dispo.ts) reject non-`.xlsx` workbook paths before staging or validation begins.
|
|
|
|
## Browser Boundary
|
|
|
|
The browser import helpers in [excel.ts](/home/hartmut/Documents/Copilot/nexus/apps/web/src/lib/excel.ts) and [skillMatrixParser.ts](/home/hartmut/Documents/Copilot/nexus/apps/web/src/lib/skillMatrixParser.ts) now enforce:
|
|
|
|
- a hard client-side file size limit of `10 MiB`
|
|
- explicit rejection of legacy `.xls`
|
|
- a tabular row limit of `5,000` data rows plus the header row
|
|
- a tabular column limit of `200`
|
|
- header validation that rejects blank and duplicate column names
|
|
- `.xlsx` parsing through `exceljs`
|
|
- `.csv` parsing through a local parser for simple tabular imports
|
|
|
|
Affected upload flows:
|
|
|
|
- resource CSV/XLSX import
|
|
- estimate scope spreadsheet import
|
|
- single skill-matrix import
|
|
- batch skill-matrix import
|
|
|
|
## Rationale
|
|
|
|
- `.xls` support keeps the old binary workbook format in the untrusted path without enough payoff.
|
|
- the server path keeps compatibility-first `.xlsx` parsing for the current dispo workbooks, but only behind explicit file validation, size limits, and `exceljs`
|
|
- the browser path moves away from blanket spreadsheet parsing to a narrower parser boundary
|
|
- export generation follows the same maintained workbook stack as import parsing
|
|
- CSV remains useful for lightweight business imports and is small enough to parse with a narrow local parser.
