“Only internal for now,” Tom said. “But the CI logs show odd requests originating from a service account tied to supplier reports. The patch is preventing new uploads. We need you to confirm the integrity of the latest files.”
Mara smiled without nostalgia. “No,” she said. “It was an accident waiting to happen. The hot patch only exposed something we needed to fix.”
If those corrections were valid, then the hot patch had done something worse than block uploads: it stopped crucial disclosures. If the company rolled forward without them, the public record would be wrong. If they accepted the mirror upload without verification, they risked admitting to a backdoor change.
“Decode it,” she said.
Mara opened her laptop and tried to breathe logically. The spreadsheet from Atwood Logistics, the one with new scope-3 figures and a promised emissions methodology, had been overdue. She’d expected it this morning. She pulled the cached version of the draft she’d worked on last night and ran the checks she always did: row counts, column headers, checksum. Everything matched, but the missing final worksheet nagged at her.
She called Tom in Security before thinking. Tom answered on the second ring, voice small over the line.
“Because their exporter is legacy,” said the Atwood contact. “We didn’t want to risk disrupting your live service. We routed the correction through our maintenance mirror. We thought it was a temporary workaround.”
