## Chapter 399 - Corners and Surfaces Tuesday existed because the year had been given an extra day. Isha discovered this at breakfast when Thomas mentioned the date while checking whether he had enough time to walk rather than take the bus. “Your calendar adds a day sometimes.” “Every four years, mostly.” “Mostly?” Thomas was putting the lid back on the yoghurt. “There are exceptions involving centuries.” Isha looked at him across the table. He reconsidered the value of completing the explanation before work. “The important part is that today exists.” “It seemed to exist before you explained it.” “Then the system is working.” She finished her tea and left him to his calendar. The email from the mineral-specimen firm arrived at 10:43. Isha was between climbing-centre tasks when she saw the sender. She read only the first paragraph before locking the phone again. A customer was waiting for a harness check, Yoshida was speaking to a father and daughter near the beginner wall, and a reply about gold had already waited a week without injury. She opened it properly during her break. The person writing identified himself as the staff member who handled mineral specimens and thanked her for the photographs. His answer was cautious enough that Isha liked it before reaching the useful part. From photographs alone, they were comfortable describing the specimen as visibly gold-bearing and dominated in part by pale vein material consistent with quartz, with darker material that could not responsibly be identified from the images supplied. The exposed gold appeared in several different relationships with the surrounding material—some broad visible surfaces, some narrower seams and irregular contacts—but photographs could not establish how far those relationships continued into the specimen. They could not provide a meaningful bulk composition from appearance. They could not identify a geographic source from appearance. They could not reliably reconstruct the geological formation history from photographs, particularly after a section had already been removed. A first physical examination would not require further cutting. Isha slowed there. The proposed sequence began with visual examination under magnification, documentation of natural and previously cut surfaces, and, where geometry allowed, non-destructive surface analysis at selected points. Any procedure involving drilling, polishing, cutting, powdering or removal of material would require a separate discussion and explicit permission. The firm was willing to begin with photographs alone if she first supplied several additional views: the existing cut face, close detail where visible gold met the pale and dark matrix, full dimensions with a metric scale, and one image under less directional light to reduce reflection. The existing assay report was optional at this stage. They would read it if she wanted them to, but the writer suggested that the first visual description could be made before reviewing the assay if Isha preferred an observation less influenced by the earlier result. At the end was a sentence Thomas would later approve of considerably. *If your primary question is what the remaining specimen physically contains and how its visible components relate to one another, that is within the kind of work we can discuss. If your primary question is commercial value or undocumented provenance, we would recommend different specialists.* Isha read the email again from the beginning. Then she returned to work. At lunch, Thomas received a forwarded copy with one line above it. `Isha: I like this answer.` He read it at his desk while Sugiyama was on the telephone two seats away explaining, for the third time and with admirable patience, that a student could not correct a university record by emailing a screenshot of a different university record. Thomas reached the paragraph about undocumented provenance and smiled. `Thomas: So do I.` He considered adding a paragraph about surface-analysis limitations, decided Isha had already understood the email perfectly well and sent only: `Thomas: Especially the fact that they have told you what they cannot answer.` Her reply came several minutes later. `Isha: Yes.` Then: `Isha: We can take the other photographs tonight.` The specimen came out of the cabinet after dinner. They treated the process with less ceremony than they had the previous week. Isha had already handled it carefully, photographed it and returned it once. Thomas cleared the protected section of table while she fetched the tray and the plain scale they had used before. The object remained visually difficult in the way dense natural material often was. Gold caught the room light too readily. Pale stone reflected more softly. The darker material seemed to disappear when the angle was wrong, leaving the brightest parts to dominate every photograph. Isha tried the requested cut-face image first. “No.” Thomas was holding a metric ruler just outside the frame. “Technical problem or artistic objection?” “Reflection.” She changed the lamp angle. The next image was better. Thomas held the ruler where she told him, then removed his hand while she made close photographs of two places where gold disappeared into pale material and one where the darker matrix bordered both. For the softer-light image, they moved the lamp farther away and bounced part of its light from the pale wall. Thomas looked at the result on her phone. “That seems much more boring.” “Yes.” “So probably useful.” Isha enlarged one contact between gold and quartz-like material. “I want them to tell me what they can see here.” She did not ask Thomas what he saw. His expertise extended to recognising that the yellow part remained gold. They took twelve new photographs and kept five. Before putting the specimen away, Isha looked at the previous cut face for a while. The earlier destructive test had been necessary when they knew almost nothing. Its absence was now part of the object's shape: one small section no longer there because they had needed an answer badly enough to remove it. She settled the specimen back into its support. “No more pieces yet,” she said. Thomas closed the cabinet after her. “Agreed.” The photographs went out that night. Nothing else did. The nameless four-person chat remained silent. After the conversation at the beginning of the week, that silence felt neither awkward nor deliberate. Ian had said good night. Kanno had passed on the sensory correction he wanted Thomas and Isha to know. There was no reason to keep talking simply because a route existed. Wednesday gave Thomas a student whose residence paperwork was complete but whose departmental system still showed an old address. The department corrected it. Thomas forwarded confirmation and did not become the owner of the address. He ate lunch away from his desk. Isha's Wednesday contained one customer who wanted advice, rejected it, tried the same movement again and then returned to ask the same question using different words. Isha answered it again without pointing out the sequence. Later she spent twenty minutes moving holds with another staff member and considerably longer cleaning chalk from places that suggested climbers could transfer chalk through dimensions unavailable to ordinary geometry. No Coach 1 dates arrived. Kanno spent the evening choosing which copies of *Until Replaced* needed inspection before 25 March. Three weeks remained before the Small Works Weekend. This was close enough to justify counting stock and far enough away that she resisted reorganising everything on the table. One copy had a corner slightly more compressed than the others. She put it in the pile she would keep for handling rather than sale. Then she looked at the Mars directory for approximately twenty seconds, closed it and returned to the booklet. Thursday remained equally inconsiderate of narrative importance. Thomas went to archery after work. At eighteen metres, the first arrow landed left of where he expected, the second low, and the third close enough to the centre to create false confidence. The next three corrected that misunderstanding. Nakahara watched one end, told Thomas his shoulder was beginning to rise again when he tired, and then moved on to someone whose bow-string problem was more urgent. Thomas lowered the draw weight for the final part of the session rather than proving anything to the target. His last arrow was mediocre. He packed the bow away satisfied. Isha's MMA session contained no opponent, revelation or unusual performance. Arai made her repeat an entry because the first version gave away too much space. Later Mizuno kept her pinned long enough that strength became increasingly irrelevant, then lost the position when Isha finally stopped trying to solve the wrong part of it. They both went home sweaty. Thomas arrived first by eleven minutes and put two bowls on the table. Isha looked into hers. “Rice, fish and vegetables.” “Yes.” “No experimental sauce.” “No.” “No dessert intended to make me reconsider my life.” “I bought mandarins.” She sat down. “Good.” He joined her. By Friday, the mineral firm had acknowledged the additional photographs and said the staff member would review them with the first set. No deadline was promised. Thomas did not send a follow-up. Isha did not either. Kanno's Friday finished late because a client had discovered that *final* could still accommodate four revised captions, a new image and a change to page order. She left work with the corrected file submitted and enough irritation remaining that she walked part of the way home rather than taking the first available train. Halfway there she remembered Miyake's invitation. The message she sent was ordinary. `Kanno: Are you still willing to show me the album repairs sometime?` Miyake replied twenty-six minutes later. `Miyake: Yes. Tomorrow afternoon if you are free. I am not working.` Kanno checked her own weekend. `Kanno: I can come around two.` `Miyake: Fine. 204. You already know the difficult journey.` Kanno looked at the apartment number and smiled. The distance from 202 to 204 was, under ordinary conditions, less impressive than Berlin, Venus or Mars. She preferred it that way. On Saturday, she arrived with two small proof prints from the wall series in a plain envelope. She had considered bringing nothing. Then she decided a conversation about photograph handling would be more useful if Miyake had actual photographs she was allowed to touch. She did not bring Venus. She did not bring Mars. Miyake opened the door wearing reading glasses and a grey cardigan, looked at the envelope in Kanno's hand and said, “Good. I was worried you might only ask theoretical questions.” “I can still do that.” “I know.” Flat 204 had the same broad architectural family as the other homes in the building and very little else in common with 202. Bookcases occupied more wall than decoration. A low worktable held a cutting mat, board, brushes and a small press, with everything arranged closely enough to imply use rather than display. Miyake had already put three albums on the table. “None of these is precious,” she said. “That makes them easier to explain with.” Kanno sat opposite her. The first was old enough for its covering cloth to have worn pale at the edges. Its spine had been repaired with a strip of new linen in a colour close to the original but plainly newer. The repair line was visible on both boards. “You could have hidden that more,” Kanno said. “Yes.” Miyake opened it. The internal repair was similarly unashamed. Several weak page folds had been reinforced. One torn guard had a narrow strip of different paper carrying the load. Nothing had been artificially stained to resemble age. “It still opens correctly,” Miyake said. “That was the problem.” Kanno ran one finger near the repaired hinge without touching it. “And if somebody dislikes seeing the new linen?” “They can dislike it.” There was no lesson attached. Miyake turned to the second album. This one had once used adhesive pages beneath clear plastic. The adhesive had aged badly. A few photographs remained in their original positions because removing them would have caused more damage; others had already released themselves at one edge and had been rehoused in sleeves with the old sequence documented separately. Kanno leaned closer. “So you did not force them all into one solution.” “They were not all in the same condition.” Miyake showed her the third. It was much newer: heavy pages, interleaving and simple removable corners holding prints without adhesive on the photographs themselves. The corners were small enough to vanish unless one looked for them. Kanno did. “Those are what you meant last time.” “Yes. For something stable enough to handle and where I want removal to stay easy.” “What if the back matters?” “Then I would not trap it against a page unless there was a reason.” Miyake reached to a nearby box and took out an example: a print held inside a clear protective sleeve, with a labelled paper sheet behind it but not attached to it. “If the reverse has writing, stamps, processing notes, anything useful, a sleeve or a loose enclosure lets you keep both sides accessible. If it is a group meant to stay in a sequence, you can still number the enclosures.” Kanno thought of folders. `2028-02-27_Mars` Actual camera files. Frames made by Ian with her camera marked separately. The digital structure already distinguished things she did not want collapsed together. Physical objects would make the same question less abstract. She opened her envelope. “These are expendable.” Miyake gave her a look. “They are test prints.” “That is different.” Kanno placed the two wall photographs on the cutting mat. One showed the pale rectangle left after a sign had been removed from concrete. The other held the rust trace of a bracket and a newer patch where the fixing had been filled. Neither belonged to *Until Replaced*. Both came from the loose set she still did not know what to do with. Miyake handled them by the edges. “What do you want them to do?” “Today?” “That is usually the safest time scale.” Kanno considered. “I want to test ways of holding them where I can change the order later.” “Album or box?” “That is what I don't know.” Miyake nodded and reached for a sheet of board. She did not build a finished object. Instead she showed Kanno three possibilities with the same photograph: removable corners on a page, a hinged paper guard that allowed the print to lift, and a loose sleeve placed inside a simple paper folder. Each made different parts of the object easier to use. The corners made the front clean and visible. The guard gave better support but turned the page into a more deliberate structure. The loose enclosure made sequence temporary. Kanno moved the second print between the arrangements herself. “If I had several kinds of photograph,” she said, “and it mattered that some were made one way and some another?” Miyake did not ask what kinds. “Then decide whether that difference belongs in the storage or only in your catalogue.” Kanno looked up. Miyake continued while trimming a scrap of interleaving paper. “If you need to know which is which every time you handle them, separate them physically. Different folders, dividers, labels. If the distinction only matters when you research them later, the record may be enough.” Kanno turned one of the transparent sleeves over. “What would you do?” “I would ask what mistake would annoy me most.” That answer was sufficiently Miyake that Kanno almost laughed. “Mixing them.” “Then do not store them in a way that makes mixing easy.” Miyake slid the wall print back to her. Nothing in the exchange required Kanno to say *Venus*. She appreciated that. They spent another hour working with ordinary materials. Kanno learned how little adhesive was needed when adhesive genuinely was the correct answer, how quickly a corner became ugly if cut inconsistently, and why Miyake preferred a slightly generous enclosure over one that fitted beautifully until humidity changed. Kanno ruined two paper corners. The third worked. “You look pleased,” Miyake said. “I made a corner.” “Yes.” “It is a good corner.” Miyake inspected it. “It is acceptable.” Kanno put it carefully beside the failures. At some point tea appeared. Miyake had made it before Kanno arrived and forgotten about it until both cups were already lukewarm. They drank it anyway. Kanno showed her the second wall print again. “I still don't know what these are becoming.” Miyake adjusted her glasses. “Then don't bind them.” Kanno looked down at the three sample structures spread across the worktable. “That is annoyingly practical.” “You asked me about book repair.” “True.” Before Kanno left, Miyake gave her a small handful of spare photograph corners, two sheets of interleaving paper and one unused sleeve. “For testing,” she said. “I can buy these.” “Yes.” Kanno put them into the envelope anyway. In the corridor outside 204, she almost turned left towards 202 from habit. Instead she stopped. Thomas and Isha were home; she could hear nothing through their door, which was the preferred condition for neighbours. She had no reason to visit merely because she was two doors away. Kanno went downstairs and walked home. The private route to Ian remained unused. So did the group chat. Sunday began with rain. Thomas and Isha stayed inside until almost noon, then went out when the rain thinned to something that did not justify an umbrella for a short walk and immediately proved that judgement wrong. They bought groceries and returned with damp shoulders. Thomas considered Cleanse. Isha looked at him. “We are already home.” “That was my reasoning.” “You are going to use magic because we failed to carry an umbrella.” “I have used magic for less.” This was true. He dried the surface water from both coats in the genkan, leaving the fabric itself unchanged, and they hung them properly afterward. No revelation followed. The mineral firm still had not replied substantively to the additional photographs. Coach 1 dates remained absent. The April working group remained in April. The next passage was now a little over a week away if the thirty-cycle estimate held closely enough. The 25 March Small Works Weekend was less than three weeks away. Neither date needed action on Sunday afternoon. Thomas read. Isha returned to the unfinished paper hanging and moved one pale-grey length twice before deciding the second position had been worse. At her own flat, Kanno emptied Saturday's envelope onto her desk. Two wall prints. Three acceptable or failed paper corners. Interleaving. One sleeve. She opened the Mars directory, looked at the group photograph and then at the portrait Ian had taken. This time she did not begin designing a final album in her head. She created three temporary folders on the desk instead. On the first piece of scrap paper she wrote: **Camera photographs — Kanno** On the second: **Camera photographs — made by Ian** On the third: **Generated / external images** She stared at the labels. Venus would fit. Mars would fit. The machine approximation would fit somewhere else. The impossible universe image was already making trouble with the third category, because *generated* and *external* were not necessarily the same thing and Ian's explanation of its provenance had never become astrophysics. Kanno crossed out the third label. She wrote: **Other provenance — describe individually** Better. She placed the three labels beside the empty folders. No photographs went into them. There were no physical Mars prints yet, and the Venus photographs remained digital apart from the separately handled reconstruction print. The folders were only a way to see whether Miyake's advice survived contact with the actual problem. Kanno moved the second and third labels farther apart. Then she used one of Miyake's spare corners to mount the ordinary wall photograph on a sheet of cheap test board. The corner sat straight. Kanno pressed the board flat beneath her hand, checked it once from the side and left it there.
