Daily Task Switching

What makes the Daily version different

Practice is open-ended and seed-based. Daily Task Switching uses the calendar date as the start of a deterministic schedule. That means the same date reconstructs the same source block, stimulus choices and F/J orientation in the same browser build. The Daily path is useful for repetition because a retry does not quietly replace a difficult switch sequence with an easier random one.

Daily does not replace Today’s 6

DailyBrainArc already has a frozen 2026 Today’s 6 contract drawn from twelve established rotation-source games. Task Switching remains outside that contract. Completing Daily Task Switching records a separate specialist history and streak; it does not add a seventh slot, replace one of the six games or change the frozen Today’s 6 sequence. This containment is rechecked during release QA.

How the 2026 schedule is built

Each date receives a deterministic seed and a difficulty chosen by the specialist's frozen distribution. The runtime materializes a candidate block and computes a complete identity from its source, response orientation and concrete stimuli. If that identity was already used earlier in the same year, the scheduler advances a deterministic variant seed until it finds a configuration not yet used. The final 2026 schedule is then measured rather than assumed to be unique.

365 distinct means actual block identity

The verifier checks all 365 dates in 2026 and confirms 365 distinct materialized identities. A different date string alone does not count as a different puzzle. This distinction matters because seeded systems can accidentally map two dates onto the same underlying configuration. The release claim is limited to the frozen 2026 schedule that was actually enumerated and should not be generalized to another year without remeasurement.

Difficulty distribution stays deliberate

The Daily schedule contains 60 Easy, 180 Standard and 125 Challenge dates in 2026. Easy uses 24 trials and two rules from one family. Standard uses 32 trials with more switches and a shorter response deadline. Challenge uses 40 trials across two families and four active rules. The distribution gives most days a substantial Standard block while still reserving easier entries and a meaningful number of high-load days.

What is stored after a Daily block

Completing the block stores the date, level, accuracy, median correct response time, repeat median, switch median, switch cost, conflict cost, timeouts and whether the run was Clean or Assisted. The specialist also keeps a local completion streak and best streak. All of this stays in the browser's versioned DailyBrainArc store. There is no account requirement and no remote leaderboard involved in the specialist contract.

Daily completion is not a perfect-score gate

A task-switching block is a speed-accuracy exercise rather than a puzzle with one final solved state. The Daily history therefore records completion instead of pretending a lower-accuracy run never happened. Accuracy, timeouts and timing metrics remain visible in the saved result. This avoids encouraging players to reload repeatedly until only a perfect outcome is preserved in the history.

Clean versus Assisted on Daily

Previewing the next rule is available on Daily just as it is in Practice because it can be useful for studying the transition. The moment advance preview is used, that run is Assisted. The Daily history preserves that classification. A Clean run means you responded cue by cue without seeing the upcoming rule early. The distinction is a transparency feature, not a punishment for using help.

Why replaying the same day can be useful

A first run shows how you handled an unfamiliar sequence. A retry lets you study whether errors came from particular rule pairs, response conflicts or simply rushing. Because the date-stable block does not change, improvement on a retry has an interpretable practice context. It is still affected by familiarity, so a retry should not be compared as though it were another fresh assessment.

Reading the Daily result

Start with overall accuracy and timeouts. Then compare repeat and switch accuracy. If switch accuracy is lower, the rule transition created more errors in that block. If both are high, compare median correct response times. Switch cost is switch median minus repeat median. Conflict cost is conflict median minus congruent median. Neither number is corrected into a population score; both are direct within-block differences.

Why Daily uses medians

A single interruption can create one extremely long response. Median timing keeps that one event from dominating the block summary. Only correct responses contribute to the median timing metrics, while wrong responses and timeouts remain visible in accuracy and error counts. That design keeps speed and accuracy from being merged into a number that hides how the result was produced.

What happens when the browser store migrates

V0.138 uses its own versioned storage key. When a populated V0.137 store is present, migration creates a new V0.138 store while leaving the serialized historical V0.137 value byte-unchanged. Existing specialist statistics are preserved, and Task Switching begins with an empty run history. Browser QA exercises that populated migration path rather than testing only a blank new-user store.

A short Daily routine

Before starting, read the active response map once. During the block, prioritize cue accuracy over anticipation. After finishing, look at accuracy and switch cost before deciding whether to replay. If the result was mostly timeouts, Practice at the same or easier level is more useful than repeatedly forcing the Daily block. If the result was accurate but slow on switches, a Clean retry can help you study transitions without changing the configuration.

What Daily Task Switching does not claim

The specialist does not diagnose attention problems, measure intelligence, certify job performance or estimate a clinical cognitive-flexibility score. A browser task is sensitive to hardware, input method, reading speed, familiarity and interruptions. The Daily format exists to provide a consistent local practice loop with transparent calculations and reproducible blocks.

Practice and Daily belong together

Use Daily when you want one fixed block tied to the date. Use Practice when you want fresh seeds, direct difficulty control and repeated training at one level. Both modes share the same source bank, rule authority and result definitions, so the terms Repeat, Switch, Conflict, Clean and Assisted mean the same thing throughout the specialist.
