- @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
.xlsxfiles. - Browser-side ad hoc imports accept
.xlsxand.csv. - Workbook import and export generation now use
exceljsinstead of direct runtimexlsxusage.
Server Boundary
The dispo-import reader in 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 throughexceljsbehind a hardened server-side parser boundary
The API entry points in dispo.ts reject non-.xlsx workbook paths before staging or validation begins.
Browser Boundary
The browser import helpers in excel.ts and skillMatrixParser.ts now enforce:
- a hard client-side file size limit of
10 MiB - explicit rejection of legacy
.xls - a tabular row limit of
5,000data rows plus the header row - a tabular column limit of
200 - header validation that rejects blank and duplicate column names
.xlsxparsing throughexceljs.csvparsing 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
.xlssupport keeps the old binary workbook format in the untrusted path without enough payoff.- the server path keeps compatibility-first
.xlsxparsing for the current dispo workbooks, but only behind explicit file validation, size limits, andexceljs - 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.
