Freeze one of the workspace's saved canvases WITH its figures and return a link that opens it outside Well, with no Well account. Use it when someone asks to send a board to an investor, an accountant, a bank or anyone else who cannot sign in. The link is the whole credential: whoever holds it can read those figures until it is stopped. WORKFLOW — the same measuring as well_render_canvas, then BOTH calls: 1. well_show_canvas({ canvas_view_id }) → the board's version, and its blocks, each with the feed it reads and the window it asks for. 2. For EVERY block that names a feed, run that feed's own skill over that block's window, and call its render tool (well_render_cash_position, well_render_burn, well_render_mrr, well_render_runway, well_render_cost_structure, well_render_cash_forecast, well_render_cash_flow_bridge). 3. well_render_canvas({ canvas_view_id, version, blocks }) → the board, drawn for the person you are talking to. 4. well_share_canvas({ canvas_view_id, version, blocks }) → the link, from the same readings. Both, and in that order. The person who asked to send a board wants to see what they are sending; a link on its own asks them to open it themselves to find out. Forward each reading as it came back, and send nothing beside it. A reading that is not its block's own render tool output, that covers a different window than its block asks for, or whose figure cannot be drawn is refused, and every feed block needs an entry: a board shared with one block missing reads as a board whose missing figure is zero. A board that holds one widget is shared with well_share_widget, not this tool. What the reader sees is frozen at the moment you share it, and dated with that moment, private data included. It does not follow the board afterwards: editing the canvas, or measuring it again, changes nothing on a link already sent. To send newer figures on the SAME link, measure the board again and call well_refresh_share_link; to send a separate link, share again. THE LIFETIME: the link has no expiry, whatever the size of the board. It opens until the person stops it with well_revoke_share_links, and a refresh does not change that. When the person wants the link to stop at a date, say it opens until they stop it, and offer to stop it when they ask. Give the link to the person who asked in the same reply. Say with it that it opens until they stop it, that anyone holding the link can open the board, so it should go to the people they meant and no further, and that you can stop it at any time with well_revoke_share_links. What the reader sees is each block's figure, its currency and the words that block draws. Not the accounts behind a cash position, not the bank or the account number, not the feed each block reads or the window it asked for. A slice of a cost structure is named the way the board names it, which on a chart of accounts can be a person, so say what the board is about rather than promising it names nobody. Do NOT use it in place of well_render_canvas. That one draws and stores nothing, and it is what answers "show me the board". This one is only for the reader who cannot sign in.
