What changes

Board fixes from using basou board on a board moved from a hand-written one. No shape changes: board_version 3, record_version 3, the record's on-disk shape and the --json shapes stay as they are.

Changed

• repos[].files leaves out a symlink that leaves the repository. A repo with agent instruction files linked in from another repo (AGENTS.md -> ../<repo>/AGENTS.md, CLAUDE.md -> AGENTS.md, .github/copilot-instructions.md -> ../AGENTS.md), tracked or untracked and not ignored, had files null at every measurement, and a built-in value takes no exclude. Unreadable paths and directories git could not list still make it null. A symlink whose end cannot be reached (a directory on the way that may not be entered) is outside when its text, or that of a link in the repo it leads to, leaves the repository. Declared measures (file_count of **) are unchanged. BOARD_REPOS_METHOD 2 -> 3: the next measure fires the axis review's trigger (e) once and the next record marks the repos section method_changed.
• http final_url holds only the scheme, host (with a port that is not the scheme's own) and path. The guide's script prints it from new URL(url_effective), or a null with an error when it is not an absolute http(s) URL; record refuses a final_url holding ?, #, a user name, a password, or a character a terminal hides. Behind a sign-in the redirect URL carried a token signed anew each time: the observation moved at every record and the token landed in a record kept in git. Records already written are not checked again, and the board page still draws their http values as parts (it holds a written value to the shape record took when it was written).
• The guide asks for all manual observations of a record in one message, and lists them as one operator turn with each key under it.
• Milestones are days on which something happened (a release, a launch, the start of the work), never a plan or a target date, in the guide and in the comment board init prints.

Added

• A files column in the repos tables of the live board and of a record's page.
• Under Claude's and Codex's time on the board page: each counts an overlap once, not a sum of sessions.

Fixed

• The per-day tile says what it divides by (the days from the start to today, both included, one more than the elapsed days beside it); docs/spec/board.md defines it.
• The guide's Source: line quotes an argument where the command quotes it (a check name with a space), and leaves a plain name as it was.

Verification

• pnpm -r build, pnpm typecheck, pnpm lint, pnpm lint:lang, pnpm lint:paths, pnpm test:scripts, pnpm -r test: all exit 0 (core 2972 passed, 1 skipped; sdk 67; cli 1599).
• Reverting each change one at a time makes its tests fail (repos files, the unreachable-end symlink, the record's final_url checks including hidden characters, the page drawing a written value with a query, the script's URL reduction, source quoting including shell-expanded characters, the manual turn, the per-day divisor, the union sub-texts in en and ja, the files column).
• The http script was run against curl 8.7.1 and a local TLS server for 25 redirect cases; every value it printed passes record's check.
