Samrawit Assefa clipped the first recovered plate tag beside the crack map and refused the terminal’s offer to group it with the others.
Internal Lot Seven filled the proposed heading. Beneath it, three transition welds carried the same green receiving status that had followed their steel into Slip Two.
The receiving checks had passed. The cracks were real. Neither result erased the other.
She locked her boots into the materials station and enlarged Wanjiku Bett’s signed examination. Article Four, the short barrel meant to connect two pressure hulls elsewhere, remained captured in its cradle. Shallow cracks occupied the heat-affected plate beside all three mixed transitions. Further proof and transfer were inhibited.
Tuva Hawthorne’s witnessed control stayed open in another pane. Same plate row, original recorded procedure and treatment, clean through repeated loading and unloading. Its retained specimen sat behind Samrawit in a clamped rack.
She needed the names the metal had carried before the yard gave it one.
The removable fabrication tags had returned to numbered sleeves when the pieces entered the barrel. Their photographs and cut records preserved which face belonged at each joint. Samrawit linked the first sleeve to its installed location, then followed the local serial back through stock withdrawal to receiving.
One complete upstream certificate hash.
The adjoining plate led to another.
She put both strings beneath the first marked transition. Long, unreadable identities to an unaided eye, but exact enough for the terminal to compare without guessing. Different hashes did not establish different metallurgy. They established two records the local label had concealed.
At the second transition, the pair repeated. At the third, again.
Every mapped cracked joint crossed that division. The indications stayed on the plate linked to the same one of the two certificates.
Samrawit saved the overlay, including the tag photographs. A colored boundary without its attachment chain would be another persuasive picture nobody could verify.
Wanjiku joined at the station rail and fastened her slate beside the map.
“You matched the inner-face references?”
“Both faces. Cut record through receiving, each piece. No reversed tag.”
The inspector checked the first location against her scan coordinates before opening the next.
Samrawit added the same-hash joints and their retained examination results. No corresponding indications in the completed coverage. The earlier same-row coupons stayed clean, too. Tuva’s new control joined that column with its limited specimen geometry attached.
The clean column occupied more screen space than the cracked one.
“Enough to name a suspect population?” Wanjiku asked.
“Enough to preserve the division. Not enough to reject every plate behind one certificate.”
Unused stock had never taken the barrel’s load. One certificate might cover more than one processing condition. Samrawit left those limits beneath the comparison rather than letting the green entries become a claim that every same-hash joint would survive.
Wanjiku attached the overlay to the nonconformance record. Her hold stayed unchanged.
Samrawit carried the slate through the access corridor on its short tether. At the quarantine cage, she caught the rail and secured herself between the two restrained rows.
Her white tape line still divided their stock positions. The plates looked alike beneath the task lamp. Portable hardness checks had separated them into two compliant clusters during receiving. She had kept them apart then, with less evidence than she had now.
A stock handler clipped into the rack station.
“Which row stays held?”
“Keep both under their current custody status. No new interchangeability clearance.”
He opened the inventory pane. One category covered both rows. Separate local serials and certificate links remained underneath, available only after expansion.
“The next withdrawal screen gives either row,” he said.
Samrawit followed the category into the local schema. Nominal structural grade. Chemistry band. Thickness and dimensions. Receiving acceptance. Those fields populated the stock-selection rule. Nothing asked how a plate had acquired its properties.
The same rule had supplied Article Four’s planning record. Their special hold and witnessed joining package had restrained its use. They had not repaired the ordinary certificate.
The handler opened a printable receipt. The category and acceptance box survived. Both upstream links disappeared from its short view.
Samrawit asked him to expand it before saving. Two additional lines returned the hashes to the page. Nothing about the plate changed, but the next worker would have a path back to the evidence instead of a reassuring label.
She kept that short view with the audit. The yard’s ordinary paperwork could repeat the omission without anyone deleting another field.
“Keep the separate links on every withdrawal,” she said. “The category doesn’t answer the joining question.”
He retained her instruction with the stock record. She took a fresh photograph of each row tag and returned to the terminal alcove without moving a plate.
The revision list opened under her existing engineering scope. She had already searched for process fields. This time she followed the action that had made them unnecessary to the receiving screen.
Two upstream hashes entered the local reissue. The grade matched. The acceptance results matched. Both shipments fell inside one logistics window.
One output category: Internal Lot Seven.
The merge entry retained its timestamp and internal authorization reference. It named the certificate fields selected for the local record. Forming history was absent from that list. Working direction was absent. Thermal history and upstream revisions had no destination fields.
Samrawit opened the next revision, then the next. Corrections to quantity and local stock positions survived. The merge action survived. None restored the technical history excluded from the reissue.
She saved the complete local revision chain, not merely the merge entry. A later correction might have mattered as much as the original omission.
Onur Tekin’s earlier sealed-record acknowledgment remained linked beside the two hashes. Origin records existed outside her scope. The local audit could not establish their contents, or whether every missing process fact survived upstream.
She added that limit.
Internal Lot Seven was a security category, not evidence of one production lot. Two acceptable receipts had become permission to select either stock row. The engineering copy had discarded the distinctions required to judge what happened when the rows met in one treated joint.
That was a failure she could document. It was not the cause of a crack she could name.
At the materials terminal, Samrawit opened a blank request rather than the offered origin-access form.
Five lines beneath each complete certificate hash:
Forming method.
Principal working direction.
Stress-relief cycle.
Final heat treatment.
Revision chain.
She added a requirement to distinguish a documented absence of a process from missing information. An empty stress-relief field could mean no cycle had occurred. It could also mean nobody had copied it. Those answers would send a joining review in different directions.
Her thumb pressed against the restraint buckle while she read the request again. She could demand everything behind the sealed acknowledgment. The demand would be easy to write and difficult to defend. A source address would not tell her whether joining heat changed the steel.
She entered the exclusions explicitly: source name, route, facility location, contract identity, destination.
Wanjiku returned her checked overlay with all three locations confirmed.
“What are you asking him to open?”
“Nothing unrestricted. These attributes for both hashes, with the revisions that establish which values applied to our plates.”
“Will they explain the indications?”
“They may distinguish the material histories. We still have to test any explanation.”
Samrawit attached the crack map, clean comparisons, merge entry and complete local audit. The request itself needed none of the yard’s location or purpose. She signed the technical need and saved it for compartmentation review. No outgoing query left the terminal.
Around the compact request, the certificate viewer held broad empty spaces where process information should have been. The existing record had room for dimensions, chemistry and an accepted check box. It had never made room for the five answers she needed.
She reduced the attachments to their linked headings.
The shortest useful request fit on one screen. Samrawit left the empty fields visible around it.
Author’s note: This story continues the Site Anvil arc in late Year 3, on the fourth day of Article Four’s investigation. A hidden yard can retain custody of its stock while losing the history needed to join it safely.
