Rules that act
Cross an operating threshold and see the model escalate review work automatically.
How-To films
Each short episode starts with a real action and follows what Grid does next. A companion guide, runnable model, or reference is waiting when you want to go deeper.
Every player, caption file, poster, and transcript is tied to its release receipt. The library currently spans Grid 0.61.0 and Grid 0.63.2 and Grid 0.66.2; each film shows its exact release.

Cross an operating threshold and see the model escalate review work automatically.
Turn a plain-text model into a live grid, then change one input and watch every dependent value—and the judgment—recompute.
Select a result, reveal its formula, and trace the evaluated lineage behind the number.
Declare data, logic, and interface together, then open the same model as a working pipeline board.
Try to combine incompatible currencies, see Grid stop the mismatch, then make the conversion explicit.
Import a workbook with its formulas intact, then change one input and watch every dependent result recalculate.
Trim one position and see totals, carry, duration, stress, and concentration move as one connected portfolio.
Model revenue and cost as distributions, widen uncertainty, and watch the launch decision change with the odds.
Change the evening price spike and watch hourly charge and discharge choices roll into a new daily P&L.
Override a computed treasury value, see the funding stack reprice, then undo to recover the original formula.
Change revenue, then look back at an earlier revision without disturbing the live model.
Walk through edits and rule firings as an event stream, inspect the past, then return to unchanged live state.
Watch an offscreen teammate change units and leave a comment while the shared model updates without a refresh.
Bring in a live FX rate, contain a failed ML signal with a deterministic fallback, and keep exposure recalculating.
Flip the same portfolio model through Source, Author, Debug, and LaTeX while its live results remain unchanged.
Turn a live approval model into a routed App, exercise one guarded action, and publish the same package as App Home.
Change one order from pending to paid and watch the live relation, revenue total, alert, and four dashboard tiles update together.
Launch a two-row experiment, compare stored summaries, verify a read-only trajectory replay, and publish immutable evidence without treating it as approval or release.
Change one dependency, watch the releasability gate move while approval stays contested, and use WHY to retain its authorities and exact graph-edge witnesses.
Resolve a source-authored Planning region into relative-time resource lanes, then reveal the makespan, objective, and repair evidence behind the schedule.
Baseline a small ReqIF set, import one controlled revision, and publish the exact structural change impact with upstream and downstream reachability.
Flip one treasury freeze flag, verify the operating classification and payment rule recompute, then isolate P5 in Flow as a legible three-node, two-edge neighborhood fed by A9 and A10.
Flip one manual-freeze flag and watch the operating mode and a recorded payment-freeze action settle together.
Change one incident latitude and let geodesic distance choose the nearest response hub.
Run four visible Dataset transforms, explicitly publish three clean rows to TrustedOrders, and verify the bound Table reads only that result.
Move Acme from Lead to Qualified on the real CRM Kanban and verify the shared Table row and stage-sensitive KPIs update from the same Accounts input.
Reschedule one Calendar event and watch the bound work rows and daily capacity recalculate through the model.
Attempt an invalid write, keep the last valid state with an authored explanation, then correct the input and settle the model.
Change one coefficient and watch factors, derivatives, roots, and exact mathematical evidence update together.
Change one allocation input, refine the reactive Visuals chart, and export deterministic SVG and PNG output.
Change one month of units and watch mapped revenue, cumulative totals, and three scenario futures recalculate together.
Change one corrected List quantity and watch the published array and restock pipeline update while the original List and folded ink total stay intact.
Change one order total and watch a named pricing function and a closed Order choice update the decision while the ledger stays intact.
Change a valid invoice reference to malformed text and watch the raw input stay visible while an anchored parse guard returns unparsed and closes the decision as rejected.
Change a valid arithmetic expression to invalid syntax and watch Grid return structured rejection evidence instead of turning the parse into a model error.
Change one poll and watch exact forecast probabilities and seats update while the same seeded draws repeat across every resolve.
Change one game payoff and watch an unstable profile gain a certified pure equilibrium with its supporting witness.
Toggle one preference and watch the matching reorganize while stability, proposer optimality, and complete assignment remain certified.
Change one demand assumption and watch bounded target-price, maximum-profit, and minimum-cost SOLVE results recompute without overwriting their candidate inputs.
Raise baseline weekly demand and compare two saved 52-week trajectories so PREV smoothing, DELAY arrivals, and STOCK inventory visibly retain model-time state without rewriting the authored inputs.
In production
These pages stay separate from the published sequence until their media and captions pass release verification.
Ask the inspector to explain net liquidity in plain language and keep the supporting evidence beside the answer.
