📝 Walkthrough
Merge Risk: 🔵 Low · up to Ordinary zero-ID tables retain their filters and metadata, but a table with an invalid column ID can attach them to the wrong column. The remaining risk is narrow and should be fixed or explicitly accepted before merging. Security Architecture Review

check to accept zero as a valid source column ID, while preserving the existing
integer and duplicate-ID checks.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick winGuard against a missing or non-numeric
idin the source XML.
Number(c.getAttribute('id'))returns0when theidattribute is absent, becauseNumber(null)is0. It returns0for an empty string too. Such a source node is then stored under key0. A model column withsourceId0can then match that node by mistake. This inherits the metadata of the wrong column. The risk is real now that the PR accepts0as a valid ID. A later node with the same key also overwrites an earlier one.Skip nodes without a valid attribute value when building
byId.Proposed fix
- const byId = new Map(source.map((c) => [Number(c.getAttribute('id')), c])); + const byId = new Map<number, XmlElement>(); + for (const c of source) { + const raw = c.getAttribute('id'); + if (raw === null || raw.trim() === '') continue; + const id = Number(raw); + if (Number.isInteger(id) && !byId.has(id)) byId.set(id, c); + }🤖 Prompt for AI Agents

What does this change?
Keep loaded table-column identities through edits, and remap saved filter criteria and preserved column metadata by those identities. Criteria follow surviving columns, disappear with deleted columns, and cannot be revived on replacement columns after repeated insertions/deletions.
Fixes #50.
