The working protocol was Tessa's idea, or at least she was the one who framed it as something they needed to have.

She said it on Monday morning, which was also the morning of Mira's eighth day in Alderheath and the beginning of what Corin had established, with his preliminary assessment, was a woodworking cycle. The secondary assessment, not a major craft week -- more joinery-adjacent than anything involving structural lumber. He had been handling the timber samples from the Bellmaker's Row archive collection for several days before the transition, which explained the orientation. It was, by his standards, a predictable outcome.

"After Friday," Tessa said, standing in the doorway of the reading room with the card index open in her hands, "I think a working protocol would be appropriate. Given that you'll both be in structures that are not fully stable." She paused. "It doesn't need to be complicated. A statement of who does what, and what happens if there's a safety issue."

She left the room.

Corin and Mira sat at opposite ends of the reading room table and looked at each other and then at the empty space where Tessa had been.

"She's right," Mira said.

"She usually is."

"Do you want to start or should I?"

He considered. "You start."

Mira took a piece of paper from her notebook -- a separate sheet rather than a torn page, which he noticed was a degree more formal -- and put it on the center of the table. She uncapped her pen.

"Mira handles architectural and documentary analysis," she said, writing as she spoke. "Corin handles material and structural assessment." She looked up. "Agreed?"

"Agreed."

"Neither of us removes objects from a site without informing the other."

"And without informing Tessa."

She wrote it. "Neither of us enters a structurally uncertain building alone."

He looked at the paper. "Neither of us enters a structurally uncertain building without communicating the entry to the other and receiving acknowledgment." The distinction was precise: not just informing but confirming receipt. She wrote his version.

"Safety equipment on site visits," he said. "Both of us carry the standard kit."

She wrote it.

Four items. They both looked at the paper.

Mira looked at it for a moment longer than reading required. Then she put the pen to the paper and wrote a fifth item without pausing: Corin will not refuse to explain why his working knowledge varies significantly from day to day without providing at least a general explanation when directly asked.

She wrote it in one smooth motion and did not look up until the sentence was complete.

Corin looked at the sentence.

He read it twice.

He picked up the pen and drew a single straight line through the sentence. Not a scribble. A line. Clean and deliberate, the way you crossed out something that was going in the wrong direction.

"You can't unilaterally remove a proposed term," she said. "That's not how negotiation works."

"I just did."

"It doesn't count."

"I drew a line through it in ink."

She looked at the line. She looked at him. He set the pen down. He could read the shift in her expression -- not anger, not yet, more the quality of a person who has asked a question and received a deflection and is deciding how to respond to the deflection rather than to the absence of the answer.

"The term is relevant to working safely together," she said. "If you have a condition that affects your physical capability on certain days, that's a safety factor."

"I don't have a condition that affects my physical capability."

"Then what does affect it?"

He looked at the crossed-out sentence. He thought about explaining. He thought about what the explanation required -- the full version of it, the version that was actually true -- and what it would do to the careful equilibrium they had built in eight days of parallel work and careful distance. The comfortable working arrangement. The productive silence.

"The term is outside the scope of a working protocol," he said. "The first four terms are about task allocation and safety procedures. The fifth is personal."

"Safety procedures include knowing whether your colleague is going to be able to do what they said they'd do."

"I'm always able to do what I say I'll do." He met her gaze. "What I do changes. My ability to do it doesn't. Those are different things."

A silence. She was reading his face the way she read documents, not looking for a single key fact but assembling the picture from multiple sources simultaneously. He kept his expression neutral, which he was better at than most people. Better than most, but not, he suspected, better than her.

"Fine," she said, and capped the pen.

They both looked at the paper.

"We sign it," he said.

She looked at him with an expression that could have been resignation or something more deliberate. Then she uncapped the pen and signed at the bottom on the right side. She pushed the paper toward him. He signed on the left.

---

They worked in the reading room through the afternoon, side by side at the long table for the first time by design rather than accident. Mira was in a second box of Bookbinders' Guild records. Corin was finishing the written assessment of the Bellmaker's Row hardware pieces and cross-referencing them with the photographic archive.

He was aware, in the course of the afternoon, of the specific quality of how she worked.

She read fast -- faster than he did, fast enough that he registered the sound of pages turning on her side of the table at a rate that seemed too quick for careful reading. But her notes were not the notes of someone who was skimming. They were detailed and specific, structured in a way that indicated she was processing fully and quickly at the same time. She cross-referenced without stopping to flip back and forth between sources, keeping the earlier material in her head well enough to note connections in real time.

He was aware that he was observing this more carefully than a working relationship required.

He looked back at his hardware assessment.

She asked, without looking up: "The large cabinet near the fire door on this floor -- what period?"

He did not look at the cabinet. He knew it. He had examined it in Cycle 68. "1890s," he said. "Construction is local, the lock is not. The dovetails in the carcass corners are hand-cut in the style that several local joiners used in that decade."

She wrote something. "Thank you."

The afternoon light was the flat even light of an overcast February, falling without shadow across the table, and in it the pages and notebooks and hardware photographs were all the same quality of visible -- clear but not bright. The working quality of a properly lit room that was doing its job without calling attention to itself.

He thought about the crossed-out sentence. Not with regret, exactly. With the particular awareness of someone who had drawn a line through a thing they knew was going to have to be uncrossed eventually, and who had drawn it anyway because eventually was not now.

He put the thought away and returned to the hardware assessment.

From the other side of the table, the sound of a page turning. Then: "The Halvern-associated members entry from 1896, and the follow-up recommending continued monitoring -- do you know who was on the committee?"

He considered this. "Three names are in the card index," he said. "The committee chair was J. Merrin. His personal records are in the manuscript collection. I don't know if you've looked at those yet."

"Not yet." She wrote something. "I'll request them tomorrow."

He looked at the hardware photograph in front of him. J. Merrin. He had looked at Merrin's personal notebook in Cycle 68, examined it as an object -- the quality of the paper, the ink, the way the pages had been turned over many years. He had not read it carefully enough, he thought now. Not from the inside.

He made a note in his assessment log: Review Merrin personal records -- J. Merrin notebook, 1891.

He looked at the note. He underlined it.

Outside the reading room windows, the grey February afternoon was becoming evening. The particular dusk of mountain towns, not dramatic, just a deepening. The sky and the stone and the river going the same shade.

He had three months before the researcher across the table from him completed her work. He did not know yet what that meant. He thought about the signed document in his coat pocket, the four terms and the crossed-out fifth. He thought about the word eventually.

He turned to the next hardware photograph and kept working. She was still reading at the other end of the table, her pen moving steadily, her concentration intact.

He noticed, and did not remark on noticing, that the room was a different quality of quiet when she was in it than when he was in it alone.

The walk back to the workshop was fifteen minutes through Alderheath's evening streets, which were quieter at this hour than they were in the morning -- fewer of the delivery vehicles, none of the school-adjacent traffic, just the particular evening movement of people who lived and worked here moving between the places where they did both. Corin took the route he usually took: south along the main street, left at the old guild boundary marker that no one else seemed to recognize as such, through the lane by the cooperage building to the northern end of the Row, and so to his workshop door.

He took the folded paper from his coat pocket and looked at it under the workshop lamp.

Four terms. One crossed-out.

The crossed-out line was still legible through the ink. He had drawn the line in a single motion, and while it was thorough, it was not obliterating. You could still read what had been written underneath if you looked at it at the right angle to the light.

Corin will not refuse to explain why his working knowledge varies significantly from day to day without providing at least a general explanation when directly asked.

He set the paper on the workbench.

The thing about the fifth term was that it was not wrong. The observation it was based on was accurate, and the request it made was reasonable given the working arrangement they were in. He had crossed it out not because the term was unreasonable but because agreeing to it would have required him to decide, in advance, to tell her something that he had not yet decided whether to tell her. The crossing-out was a deferral, not a refusal. The distinction mattered to him even if it had probably not been legible to her.

He was aware that she had registered it as a refusal. He was aware that she had said fine with the quality of someone who was setting something aside rather than abandoning it.

She was going to ask again. Not the same question, or not in the same form -- she was too careful for that. She would approach it from a different angle, at a different time, when the context was different and the question came up naturally rather than being stated as a term in a protocol. She would look at the Merrin records and she would ask him about them. She would notice the pattern in his competence -- she had already noticed it, the fifth term was evidence of that -- and she would accumulate evidence with the systematic attention he had been watching all afternoon, and eventually she would have enough to ask the right question.

He did not know how he felt about that.

He had told Tessa the essential fact, eighteen months ago, because Tessa needed to know in order for the working arrangement to function. He had told Rosch everything, because Rosch's job was to help him and Rosch could not help him without the full picture. He had not told anyone else. The researchers who had come in the early months had been told the minimum necessary to conduct their assessments, which was very little, and they had accepted the minimum because they were primarily interested in the data rather than in Corin as a person.

Mira Solenne was interested in the data too. But she was also, he thought, interested in him as a person. Or at least in him as a variable she could not account for, which amounted to the same thing in the initial stages of research.

He folded the paper back along its crease and put it in the drawer where he kept the Ledger when it was not in use. Not with the Ledger -- it was not the same kind of document. But in the same drawer. The drawer for things he was keeping.

He went to bed at ten, which was early for a Monday. He was in the first-day period of the woodworking cycle, the joinery orientation coming in clearly now, and early nights on Day 1 helped the acquisition settle. By tomorrow he would be able to identify the grain direction of most common timber types by touch and would begin to understand what the Bellmaker's Row cabinet carcasses were trying to tell him about the people who had made them. By Day 3 he would be fluent.

He lay in the dark and thought about the reading room and the flat even light of the afternoon and the sound of pages turning on the other side of the table. He thought about three months and what that was: twelve cycles. Twelve weeks of being different things and knowing different things and demonstrating, without intending to, that he was different things and knew different things. She was already tracking the pattern. In twelve weeks she would have enough data to describe it accurately even without his telling her.

He thought about telling her.

He thought about the crossed-out line and what it had meant for her to write it and what it had meant for him to cross it out. The exchange of statements. Her statement: I have noticed this. His statement: Not yet. The implied third statement, which neither of them had made but which had been present in the room: Not never.

He had not said never because he did not know whether it was never.

He closed his eyes.

Outside, Alderheath settled into its nighttime sounds. The river. The wind off the ridge, continuous and low. In the morning there would be work to do: the hardware assessment to finish, the Merrin records that Mira had requested, the question of what he was going to do about the fact that she was going to find those records and read them and look at him with her particular quality of attention.

He had managed this situation for eighteen months without anyone outside the two people who needed to know finding out. He was not sure he was going to be able to manage it for three more months with Mira Solenne in the same reading room.

He was not sure, if he examined the feeling carefully, that he wanted to.

That thought was new. He let it sit in the dark without doing anything about it, and then he went to sleep, and in the morning there would be woodworking and a long list of hardware and the Merrin records on the shelf, waiting.

He thought about it one more time before he slept, and then he put the thought in the same place he put all the thoughts he was not yet done with -- the space between the last thing he wrote in the Ledger and the first thing he would write tomorrow morning -- and let it wait.

The woodworking competence was settling in his hands with the particular clarity that Day 1 sometimes had, before the roughness of the transition had fully resolved. He could feel the grain direction in the sheets of the bed, the specific quality of the cotton weave, the way the wood of the shelf by the bed was different from the wood of the headboard -- species, probably, and certainly different finishing methods, a lacquer on one and an oil on the other that his hands distinguished automatically, the way during bookbinding weeks he could feel the quality of paper through his fingertips.

This was the thing that never stopped being strange: the absolute normality of it, once it arrived. The new competence did not feel like something grafted on or borrowed. It felt like remembering. It felt like knowing, from the inside, in the way that skills that had been truly learned felt -- not like performance of an acquired technique but like extension of self. He was a woodworker, this week, in the same way he was himself: without effort, without performance, as a condition of existing in his own body rather than as an overlay on top of it.

By Thursday he would be able to tell you things about every timber joint in the Bellmaker's Row buildings that were not in any reference text and could not be known without the specific quality of attention he had this week and not others.

By Monday he would not remember any of it, in the way that mattered.

He slept, and in the morning the workshop was cold and the coffee was dark and Halvern Ridge stood at the top of the window in the grey February morning, patient as it always was, and the Merrin records were on the archive shelf waiting for Mira Solenne to request them, and none of that was yet requiring anything from him except to be present in the week as it was.

So it was. The morning would be woodworking, and it would be enough to do.
