Case films 02–05: gateway, HTTP 413, row lock, costing
The /portfolio page now plays five case films. Facts sourced from SKAX STAR docs; people scenes only where the sources record real collaboration.
Four films added on top of the Case 01 grammar: 46-endpoints→1 gateway (senior's security pushback answered with a PoC, then hardened by him), HTTP 413 → PK-only payloads (easy fix rejected — shared server), duplicate LOT IDs → Oracle FOR UPDATE scoped to one row and shrunk to one statement, and the costing project (single-intake anchor role, 7.7K-line PL/SQL → per-process CTEs, thank-you letter at month 7).
Numbers come from the resume; narrative and quotes from ds-forge SKAX docs. Where sources conflicted (STAR notes say "about 40 APIs", resume says 46; customer wanted 50 LOTs, resume claims 80), the published resume number won. The row-lock film has no people scene because the sources record no collaboration facts for it — nothing invented.
Player change: films start when scrolled into view (IntersectionObserver) so five don't animate simultaneously.
What it doesn't do: films for distributed-lock, multi-plant, validation, and Dure TCP still text-only on faangforge. Not deployed yet.
