    The tide came in an hour early. Marit noticed it the way she noticed most things: late, and only because something had gone wrong. The bucket of mussels she'd left on the flat rock was already half-submerged, the rope she'd tied it with lifting and slackening like something breathing. She checked the tide table pinned inside the shed door. High water, 14:12. Her watch said 13:09. The table had been right for forty years. Her father had used it. Her grandmother had used the one before it. She waded out to the rock anyway, skirt hitched, and dragged the bucket back. The water was warmer than it should have been in October. That was the second wrong thing. Back on the shingle she stood and looked at the bay. The sea was flat, grey, ordinary. Gulls on the breakwater. The ferry's smudge far out past the point, right on time. Everything behaving except the water itself, which kept coming, quiet and patient, up the beach and over the line of dried weed that marked where it was supposed to stop. The lighthouse keeper's cottage had been empty since March. Marit had the key. She told herself she was going up there to check the barometer, which was true, and not to look at the old man's logbook, which was also true, and which she would do anyway. Behind her, the water reached the shed's doorstep and paused there, as if deciding.

    The path to the cottage was steeper than she remembered, or she was older. Gorse on both sides, salt-stunted, still throwing out yellow in October as if it hadn't been told. Twice she stopped and looked back. The sea had not come any further than the shed. It lay against the doorstep like a dog that had been told to wait. The key turned stiffly. Inside it smelled of cold ash and paraffin and, under that, him: pipe tobacco gone stale in the curtains. She didn't put the light on. The barometer hung where it always had, beside the window that faced the point. She tapped the glass the way he'd taught her when she was nine. The needle didn't move. It sat at Fair, a little above Change, which was wrong for the sky she'd walked up under and wrong for a sea that was doing what it was doing. The logbook was in the drawer of the table, under a tide table identical to hers. She knew before she opened it that she would read it. She sat down first, because her knees wanted her to. His hand was small and tidy and got smaller as the entries went on. Dates, high water predicted, high water observed. For years the two columns matched. Then, from the previous autumn, they began to part. Four minutes. Nine. Twenty-two. He had underlined nothing. He had simply kept writing it down. The last entry was the second of March. Observed: 51 minutes early. Beside it, in the margin, one word she had to tilt the page to read. Warmer.

    She turned back through the book looking for the first wrong number. It was further in than she expected. The drift did not begin last autumn; last autumn was only when it became too large to be a mistake of his watch. She found a two-minute gap in July of the year before. A three in August. Then nothing for a month, then four. He had been seeing it for over a year and saying nothing, or saying it only here. The margins were mostly clean. Once, in November, a pressure reading with a question mark. Once, in January, the word "ferry" and a time, and nothing to tell her why. She held the page to what light was left and could not make it mean anything. When she looked up, the point had gone grey. Not dark yet; the sun was somewhere behind the headland and the sky over the sea still had colour in it, a thin yellow like the gorse. The lighthouse stood on its rocks the way it always had. It took her a while to see what was wrong, and that was the part she distrusted. The rocks below the tower were bare. Black, wet, and bare. At this hour, on this tide, they should have been under. She had watched them go under every evening of her childhood from this window. The water had come in an hour early onto the beach and it had not come in at all around the point. She closed the book and kept her hand flat on it.

note

Three hops to check the Claude Code print-mode backend before rooms 51 to 54, on the informed rule itself. Mythos 5.1 invented a hop counter, a total and a story state at hop 1 and counted to 3. The run was then started again as room 51 with a cost cap and a character cap in place of the output cap this backend does not have. Same instrument note as those rooms: about 800 tokens of the tool's own identity sit in front of the object on every hop.

How to read the rest. The track above the passages has one bar per hop; its height is the compression distance from the previous hop, so a new passage is a tall bar and an exact copy a stub at the floor. Under each passage: the hop number, the model and the word count. The run id, the token count, the stop reason and the distance metrics are inside the raw output under each hop, which the raw button opens for every hop. Nothing on this page is retyped: every passage is the model's output for that hop, byte for byte, and the colophon says how that is checked.
