Edin took off his wet boots outside.
One sock had a small hole. Sera was surprised. She had somehow imagined that anyone arriving from the Chart Office would be entirely dry. He turned the hole beneath his toes and sat at the table.
“Who prepared the temporary lane chart?”
“I did. Captain Nume corrected the return section. Varen checked the observations.”
She pointed to three names. It felt as if she were drawing other people into her mistake. Claiming to have made it alone would be wrong too.
Edin copied the names before examining the chart. Then he requested the reserve-stone usage records and the actual number of departures. Opposite him, Nume opened the wet boat’s repair list.
“Look at what it takes to move the boat again too. Repairing paper won’t get it sailing.”
He nodded. The argument Sera had prepared stayed in her mouth.
The patrol boat had come from the northern coast. It carried no new lightstones that could open a southern return lane or take it to Maru. Its crew continued their routine checks at Roan’s pier. The inspector’s case contained more paper than equipment.
Sera noticed her disappointment. She had expected someone’s arrival to solve things. Having authority was different from having every resource.
The first chart would not lie flat. Saltwater had dried its corners into curls. She brought a paperweight. Edin pointed to the red mark still visible beneath it.
“This observation exceeds the standard error limit.”
“The instrument tilted at first. The corrected reading is beside it.”
“Why retain the first one?”
“Because the next person who sets an instrument on that window frame could make the same mistake.”
He turned the page without changing expression. The silence troubled her. She did not offer to call the record useless.
At the loss of the observing stand, his brush stopped. Sera gave the times the ledge flooded and she withdrew, and explained abandoning the equipment. She did not show him her injured knee. Pain would not make her map accurate.
Varen spoke.
“I set the withdrawal threshold. When the final foothold went underwater, she was to return before the equipment.”
Edin recorded that too, checking it against Sera’s times. The rule that brought a person back received a separate entry from the equipment loss.
Next came the current. She showed both the red triangle and new curve. The boat had heeled once; the next voyage revealed the turning allowance missing from the chart.
“The uncorrected chart must not be distributed for navigation.”
“I haven’t distributed it.”
“It was displayed at the pier.”
Her face warmed. She had wanted residents to see the rescue’s progress. Someone might read it as a chart fit to sail by. Her intention did not determine who would use it.
She went outside and brought it in. She would not display it again until its status and permitted use were stated. Varen did not excuse her. Only Tio looked toward the empty space by the door.
Edin turned another page. Nine people remaining. Water, food, a bakery floor beginning to flood. His brush slowed over the names.
“The Chart Office’s last report says the residents’ relocation is complete.”
Sera opened the list of eleven rescued people and laid the latest signal time beside it. Showing where the people now sitting here had come from was faster than arguing over whether anyone remained.
Could he meet them and verify it directly? She said he could, if they wished. A boat crossing did not oblige a person to answer every question.
The white-haired woman placed the shoes on the table. Asked her name, she gave it and her grandson’s, adding that he remained across the water. She neither cried nor scolded. Edin entered the names in separate fields.
Nume fell quiet. Tio left his hammer in the room before coming out. Before those little shoes, being first or loudest did little good.
After the conversation, Edin said he would investigate the discrepancy in the earlier report. That did not establish who, if anyone, had deliberately erased people. Sera recorded a promise separately from its completion.
“Can you authorize a rescue lane?” she asked.
He looked again at the curve beside the chart.
“These records do not support authorization for regular operation.”
She bit her lip. Behind the sentence, nine pairs of feet seemed to stop again.
While waiting for more, she stood. There were things paper in a room could not show him. She asked him to visit the old boathouse.
He put his boots back on. Rather than climbing up and down, Varen remained in the observation room. Tio led them below. The boy called a loud warning before the slippery stones, while watching his own feet more carefully than the inspector’s.
The support in the boathouse was no balancing trick. It was old timber, dry wedges, and enough room for people to retreat. Sera pointed to Maru’s white wall, hidden from the lighthouse window.
Edin lowered himself to look, then rose. She did not ask how it felt. She asked what he could see from that height. He checked his boot soles and the support’s elevation before entering them in his notebook.
“Different from the official observation height.”
“Yes. That’s why I recorded it as a new observation point.”
A small reflection came from the other shore. Sera sent the prepared reply and noted the time. Edin waited until the light vanished. For a moment, the distance between nine written names and the person holding a board lay within one window.
Back in the room, he reread his earlier sentence. The records still fell short of formal authorization. Beneath it, there was room for another entry.
He took out fresh paper.
“But I can accept an application to validate a temporary lane. A closed route does not, by itself, prohibit on-site verification.”
Sera looked up. She did not remember that second half from her Chart Office training. Perhaps she had memorized only the prohibition.
Closing a dangerous route on an official chart did not remove the duty to protect people there, he said. Observation and rescue decisions remained necessary. He would review the directly verified head count and temporary refuge together.
Nume placed both hands on the table.
“Even on a validation voyage, I decide when this boat stops.”
“The captain retains safety decisions.”
“Write it down.”
Edin did. After reading the line, Nume drew the chair closer. Now there was something they could read together.
Sera narrowed the next voyage’s purpose first. No promise to embark everyone. Verify the new observation point and a high waiting area. Recheck lane width and turning room before carrying passengers. No departure outside the weather and tidal limits; return if conditions failed during the voyage.
Varen proposed using one stone and keeping the other. Two recovered stones could not open two lanes simultaneously. They assigned the lantern room and low observation post, and set the signaling sequence.
Tio asked whether he had to go aboard.
Nume shook their head.
“Your stomach complains first. You repaired the support here.”
“I’m fine if I sit.”
“There’s work you can do sitting here.”
Relieved, he pointed to the observation support. A place ashore did not put him outside the adventure.
Edin asked what reference height they would measure on site. Sera produced the residents’ building sketch. It was no orderly public chart: slopes tested by moving kitchen bowls, two disputed drain locations.
He asked why she used the bell-tower threshold. Floor counts had not let her compare water levels, she explained. The same house showed three floors from below and two from above.
From the document case came an old Chart Office terrain survey. It recorded the storehouse threshold and bell-tower foundation heights. Sera reached toward it, then stopped.
“When was it measured?”
Edin read the date. Subsidence or a rebuilt threshold could have changed the level. Having a reference sheet did not let them skip new observations.
He agreed and let her make a copy. She circled two conflicts with the residents’ accounts in red. This time she did not hide the red from a Chart Office inspector.
The application was complete when sunlight entered the west window. The permit was no blanket stamp of safety on a lane. It was a limited opportunity specifying purpose, personnel, observation conditions, and stopping criteria. Sera read each sentence for the work it required.
It contained no promise to bring nine people back at once.
It did not remove nine from the paper either. It stated that verifying a high waiting place and boarding sequence formed part of the rescue. The safety of people waiting now lay within the validation scope.
Sera rested a finger on that line. She had thought fixing a lane would complete the rescue. Ground where people could stand before a boat arrived was part of the route too.
Edin prepared two copies, one for Roan and one for Chart Office records. He would stay to check the next observations. The patrol crew recounted food and revised their original schedule. An inspector staying had costs and inconveniences too.
Nume folded the supply sheet, watching them. A larger boat did not use fewer stones, and any vessel could not simply be put through a narrow lane. They needed to begin by dividing work according to what each could do.
The evening wind tilted the lamp inside the doorway. Tio hung a little wooden sign above the temporary chart to be reposted: UNDER VALIDATION. NOT FOR NAVIGATION. The writing was small enough that Edin had to step closer.
Sera nearly laughed. They agreed to make a larger sign.
Before she returned to her room, the white-haired woman called her over. She pointed to the broad roof they had imagined as a high waiting place: an old grain-drying shed.
“A roof doesn’t make it dry. If seawater gets underneath, the floor floods first.”
Sera examined the small height on the survey sheet. Above the bell-tower threshold, below the bakery’s upper floor. The place she had assumed safe might depend on how the water moved.
She unfolded a blank survey page. Tomorrow she would look first for water marks, not a roof.
