What changed, not the private recipe.

Posterior release notes are written for users: what improved, what it changes in the daily MLB workflow, and how the product is becoming more useful. We avoid raw commit notes and implementation recipes so the product stays transparent without giving away the work that makes it different.

The Wire leads somewhere useful

Every source-linked Wire story now has a clearer path into the baseball record behind it: the original report, the relevant club desk or player almanac, the public methodology, and the settled ledger. Posterior also measures those paths without collecting story titles, searches, or personal data, so the team can improve what readers actually use.

What changed for users

  • A breaking MLB brief can now lead directly into its player or club context and the public record that explains Posterior's standard.
  • Readers arriving from Google or an AI answer get the same evidence path as readers who start on the homepage.
  • Existing Calibration, Guide, and Changelog pages are now included in the public sitemap for reliable discovery.

Release notes

  • Wire links for the source report, team desk, player almanac, methodology, and public record.
  • Privacy-bounded Wire and evergreen-page discovery measurement.
  • Expanded public sitemap coverage for Calibration, Guide, and Changelog.

Added historical product entries.

Every receipt reads cleanly

The public Decision card now keeps each quote, probability, timestamp, and filing note in a clean definition pair. Screen readers, search agents, and browsers can follow the same receipt structure as fans without losing the detail beneath each field.

What changed for users

  • Assistive technology can navigate the public Decision receipt as four clear label-and-value pairs.
  • The note beneath every quote, probability, timestamp, and filing time stays attached to the value it explains.
  • Nothing about the card's evidence or visual layout changes — the structure underneath is simply correct.

Release notes

  • Valid accessible definition-list markup on the public home-page Decision card.
  • Quote and receipt context remains attached to its corresponding value for browsing agents and assistive technology.
P-26.08.049 · Reliability

Search lands on the real desk

Posterior's public search signals now describe the same things fans see: the delayed record carries a complete dataset description, game pages identify their ballpark and organizer, and the access page presents one clear monthly offer instead of a site-wide product card on unrelated pages.

What changed for users

  • Google can understand the public record as a documented dataset, with its owner, license, and downloadable ledger attached.
  • Game-result pages carry complete ballpark and league context for richer event discovery.
  • Search snippets no longer treat every Posterior page as a product listing.

Release notes

  • Complete Dataset metadata on the public Today desk.
  • Complete game Event metadata on live and ticket pages.
  • One valid Posterior Pro monthly offer on Pricing only.

Resumes, not tipsters

People becomes a public skill directory of real baseball records. Every card is a compressed baseball CV — Baseball IQ with the ladder tier, settled season record, best call type with its hit rate, live streak, and the most recent notable call. Discovery sections rank by what matters: top IQ, beating the model, longest streaks, category leaders. Individual resumes gain the full breakdown: record by call type, model-agreement rate, and recent settled cards.

What changed for users

  • Dense resume cards: handle, club, IQ and tier, W–L, best category with hit rate, streak, and a recent notable result — decide in three seconds whether a record deserves a follow.
  • Discovery ranks by earned signal — Top Baseball IQ by default, plus Beating the Model, Longest Streaks, and Category Leaders once samples are real.
  • Every resume page now carries the settled record: IQ, streak, per-category hit rates, how often they sided with or faded the model, and their recent settled cards.
  • Every account is claimed through Play; records settle from box scores — never self-reported.

Release notes

  • People directory rebuilt as ranked resume sections with dense cards.
  • Public resume pages gain the IQ/record/streak/model-agreement stat block, category table, and recent settled cards.
  • Honest early-stage line while the directory is small.

The board tells you what you missed

Three honest nudges, no invented pressure. The public Today desk now counts down to the board's real deadline — first pitch — and shows what yesterday's graded board actually did, losses included, straight from the filed recap. And in Play, when the machine holds its own on your card, the verdict banner points at the official desk where it plays its full hand.

What changed for users

  • A live first-pitch countdown on the public desk — the board's genuine lock, not a marketing timer.
  • Yesterday's real record on the paywall: wins and losses from the public recap, with the receipts one click away.
  • Play's verdict banner bridges to the official board only when Posterior actually matched or beat you on shared calls.

Release notes

  • First-pitch lock countdown on /today for non-subscribers.
  • Yesterday's graded W-L line with recap link on /today.
  • Machine-authority bridge line on the Play verdict banner.
  • Recap payload additively exposes the graded day's own W-L.
P-26.08.046 · iOS App

Parlays come to the phone

The iPhone Today desk catches up to the web board: the daily recommended-parlay menu and the hot-form lane — parlays built from in-form players — now render as native cards, leg by leg, with each leg's win rate and the combined number. Same locked Decisions, same honest empty states.

What changed for users

  • Hot right now: the in-form-player lane from the web board, as native cards.
  • Recommended parlays: the daily menu with tier, risk profile, per-leg players and win rates, combined probability, and the theoretical price.
  • Reference context only — never an official bet, exactly as the web board frames it.
  • Days without an honest menu show nothing rather than filler.

Release notes

  • Today API ships the parlay menu and hot-form lane (additive).
  • iOS Today renders both as card bands under the Decision desk.

The graph speaks integers again

A driver-level type mismatch made every capped graph read fail silently — the People directory said nobody had a handle while handles existed, results panels sat empty, and the Play settle sweep could not even list the picks waiting to grade. One fix at the single choke point repairs them all, and the People page gets the design it deserved: resume cards with faces, clubs, and a door that reads like a clubhouse.

What changed for users

  • People now lists every public handle — resume cards with avatar, display name, club colors, and a straight line to the resume.
  • Play picks that were stuck ungraded settle on the next sweep; results, verdicts, streaks, and the settled-card notification flow from there.
  • Every capped listing that quietly returned empty — activity feeds, league leaders, recent results — reads correctly again.

Release notes

  • People directory redesigned and actually populated.
  • Play settlement sweep unblocked; pending picks grade on the next cycle.
  • Query parameters normalized to integers at the graph driver — one fix, every listing.
P-26.08.044 · iOS App

Store-ready polish

The iOS tab bar drops a stray technical entry that could appear beside Play, and this build is the App Store release candidate — same app, tightened for review.

What changed for users

  • The bottom bar reads exactly five tabs: Today, Play, Markets, Wire, More.
  • Receipt pages still open from Play and from shared links — they just never impersonate a tab.

Release notes

  • Stray receipt-route tab removed from the iOS tab bar.

Club Wars and the trophy case

Your card now plays for your club. Club Wars pools every member's settled week under their primary club and prints the clubhouse standings — a club appears once it has a real crew of two or more settled players. And the trophy case opens: every achievement in the set on display, earned in copper, unearned as an honest outline with exactly what it takes — including four new receipts: Sharp Mind, No Way, Century Club, and The 162.

What changed for users

  • Clubhouse standings on the card page: weekly settled points pooled by primary club, ranked, with your club highlighted.
  • Clubs below the two-player crew minimum are counted as forming, never printed as fake totals.
  • The trophy case shows the whole set with plain requirements — collection pressure without invented numbers.
  • New receipts: Sharp Mind (2,000 Baseball IQ), No Way (land a 4x call), Century Club (100 settled calls), The 162 (162 cards locked).

Release notes

  • Club Wars weekly standings panel with crew counts and forming-club notes.
  • Trophy case with earned/unearned states for all eleven achievements.
  • Achievement engine now grades IQ, hardest-won multiplier, and cards locked.

The card changes shape

Tonight's Gauntlet stops repeating its silhouette. Beyond rotating names and phrasings, the card's structure itself now changes night to night: the second-name slot alternates between a hit call and a 2-plus total-bases call, and the closer alternates between the first-inning call and a second game winner from elsewhere on the slate.

What changed for users

  • Different shapes on different nights — some cards close on the first inning, some on a second game to win.
  • Total-bases calls join the rotation, graded from the box score like everything else.
  • Rotation is deterministic per date: everyone sees the same card, and replays never flicker.
  • Thin slates degrade honestly — one game on the schedule still closes with the first-inning call.

Release notes

  • Second-name slot alternates hit / 2+ total bases by date.
  • Closing slot alternates first-inning call / second game winner by date.
P-26.08.041 · Posterior Play

You, the model, and the crowd

Locking a call now starts a conversation. The reveal shows Posterior's number on the call — 57% BAL — beside how the crowd has split, with one plain sentence about where you stand: with the model, with the crowd, or fading both. Settled results carry the same three-way context, share receipts name where you beat the model, and the free card gets a front door on the public Today desk.

What changed for users

  • Post-lock reveal: the model's percentage and side on every call it leaned on, plus the crowd split, plus your relation line — "You faded both the model and the crowd."
  • Settled days show how the room leaned next to how the model leaned and what actually happened.
  • Share receipts name the calls where you beat the model and carry the you-vs-Posterior score.
  • Today desk: a Posterior Play section with tonight's anchor call and the live community lean — the free layer, visible where fans already are.
  • Thin signals stay honest: below ten locked calls the crowd reads as still forming, never a fake percentage.

Release notes

  • Post-lock reveal block: model % + side, crowd split, relation line.
  • Crowd context on settled result rows.
  • Model-context lines on the play share receipt.
  • Play teaser section on /today with honest low-signal state.

Your call is live

The moment your player steps in, the card tells you: AT THE PLATE RIGHT NOW. A landed call pops the instant it happens, and every settled night now shows how it moved your Baseball IQ — on the verdict banner and in your results, day by day.

What changed for users

  • Batter calls flag the exact at-bat: your player standing in, the inning, and what a homer here would do to your card.
  • Landed calls animate once, the moment they land — motion only ever means something just happened.
  • Every settled day shows its IQ movement: the verdict banner and your results both carry the +18 (or the damage).

Release notes

  • At-the-plate live flag on pending batter calls.
  • One-time landed-call animation, Reduce Motion respected.
  • IQ delta per settled day on the verdict banner and results panel.

Baseball IQ — prove you know ball

Play stops being a quiz and starts being a rating. Every graded call now moves your Baseball IQ — an honest skill number that climbs a baseball ladder from Rookie Ball through AA and AAA to The Show and beyond. Tonight's Gauntlet opens with who you are: your IQ, your rung, your streak, your club rank, and the call types you're best and worst at. Calls show real game mechanics — difficulty dots and what the call actually pays — and once enough of the crowd has locked a side, you see how the room split.

What changed for users

  • Baseball IQ: starts at 1,000, moves on every graded call, weighted by difficulty — winning a longshot moves you far more than winning a coin flip, and it is always recomputable from your history.
  • The ladder: Rookie Ball → A Ball → AA → AAA → The Show → All-Star → MVP → Posterior Elite, with the distance to your next rung always visible.
  • Your strengths, named: best and weakest call categories once you have a real sample — no zero-padded stats.
  • Difficulty dots and honest worth (the real 50-point stake times the frozen multiplier) replace bare sportsbook-looking multipliers.
  • Crowd splits per call, shown only once at least ten players have locked that call — a split of three is a rumor.

Release notes

  • Gauntlet strip above the card: Baseball IQ, ladder tier, streak, club rank, career record, best/weakest categories.
  • Tonight's Gauntlet headline; the open board reads as a challenge, not an apology.
  • Per-call difficulty dots, worth-in-points, and thresholded crowd splits.

The verdict finds you

When the last call on your card grades, Posterior tells you — a push notification with the night's verdict: your score, the machine's score on the same calls, who took the night. On iOS, Play catches up to the web's full loop: the verdict banner, your streak on the line, live standing under every pending call, and the machine's revealed side after you lock.

What changed for users

  • One push per settled card — "You beat the machine · You 4/5 · Posterior 3/5" — tap it to open the call-by-call verdict.
  • Card verdicts respect the same settlement-alerts switch as everything else you lock; turn it off and Posterior stays quiet.
  • iOS Play now shows the verdict banner, streak-on-the-line, live sweat lines, and the machine reveal — full parity with the web card.
  • iOS also gets the answer-mapping fix: your pick always displays against the exact call you answered.

Release notes

  • Push notification when your Play card fully settles, with the you-vs-Posterior verdict.
  • iOS Play: verdict banner, streak note, per-call live standing, machine reveal after lock.
  • iOS pick display re-attaches answers by exact call identity.
P-26.08.037 · Posterior Play

Sweat the card in real time

Your locked card now follows the games. Every pending call shows its live standing — a hit already in the book, four strikeouts through five innings, your side up two in the eighth — straight from the same MLB feed as the scoreboard. If you're on a streak, the card says so before you lock. And on phones, the card becomes a one-call-at-a-time deck you can swipe through.

What changed for users

  • Watch your calls move while the games play: hits, homers, strikeout counts, first-inning results, and the score from your side's point of view.
  • Calls that have effectively decided say so — a recorded hit has landed; a run in the first has got away — with the official grade still coming from the box score.
  • Your win streak is named at pick time: what tonight's card puts on the line.
  • On phones, the card reads one call at a time — swipe through five big cards instead of scrolling a form.

Release notes

  • Live standing line under every pending pick on a locked card, refreshed with the page.
  • Streak-on-the-line note while the card is open.
  • Mobile: horizontal one-call-at-a-time deck with call counter; desktop list unchanged.
P-26.08.036 · Posterior Play

A fresher card, and the machine shows its hand

Play stops feeling like the same quiz every night. The card rotates its featured names — yesterday's stars sit out when the slate offers alternatives — and the phrasings change day to day. After you lock your card, Posterior reveals its own side of every call, and when you return the next day the page opens on the verdict: did you beat the machine last night? Also fixed: answers now always display against the exact call you answered.

What changed for users

  • Yesterday's featured batters rotate out when the slate has other names, so the card reads fresh every night.
  • Lock your card and the machine shows its hand — Posterior's side of every call, flagged where you're against it.
  • Come back the next morning to the verdict up top: your score, Posterior's score, who took the night.
  • A display bug that could show your answer against the wrong call (two same-type calls on one card) is fixed.

Release notes

  • Play card rotates featured players and phrasings day to day, deterministically per date.
  • Post-lock reveal: Posterior's side on every call, with an against-the-machine flag.
  • Verdict banner on return: last settled card, you versus Posterior.
  • Locked answers now re-attach to calls by exact identity, never by loose type matching.

The plate, in your pocket

The iOS live board catches up to the web's broadcast view: the at-bat opens on batter versus pitcher with official headshots, their real lines from tonight's boxscore, and the count big enough to read at a glance. The pitch locator stands the same true-proportion batter silhouette on the correct side of the plate, and Play now shows your results — every settled day call by call, with your running record against Posterior on the same calls.

What changed for users

  • iOS at-bat: faces, tonight's actual lines — 2-4 with a homer, 5.1 innings on 87 pitches — and the ball-strike count with outs as dots, live at-bats only.
  • The traced batter silhouette from the web locator, identical path and zone calibration, mirrored to the measured batting side.
  • Play on iOS keeps your record: settled days call by call, career line, and the you-versus-Posterior score on shared calls.

Release notes

  • iOS live board: at-the-plate card with headshots, boxscore lines, and the live count.
  • iOS pitch locator: true-proportion batter silhouette on the measured batting side.
  • iOS Play: "Your results" — graded history plus the same-call record against Posterior.
P-26.08.034 · Posterior Play

Your record, call by call

Play now keeps your results. A new panel on the card page shows each recent settled day call by call — what you took, what actually happened, and what Posterior's own number favored on the identical call — plus your career record and a running you-versus-Posterior score on shared calls.

What changed for users

  • Every settled card stays visible: your side, the outcome, and the multiplier you played, day by day.
  • You versus Posterior is scored honestly on the same calls — when Posterior's number had no lean, the call counts for nobody.
  • Your career line — wins, losses, hit rate — sits on top, built from every pick you have ever had graded.
  • New visitors see the free game from the front page: follow your club, play the card, check the record — before anyone talks about pricing.

Release notes

  • Play card page: new "Your results" panel with each recent settled day, call by call.
  • Career record (wins, losses, hit rate) across every graded pick.
  • You-vs-Posterior score on shared calls, graded on Posterior's own frozen number for the identical call.
  • Homepage: a fourth door — "Make your calls. Beat the machine." — routes fans straight to the free daily card.
P-26.08.033 · Live Games

A real batter in the box

The pitch locator now stands a true silhouette of a batter beside the strike zone, drawn to real proportions: knees at the bottom of the zone, letters at the top, feet on the ground. He takes the correct side of the plate for the batter actually up — lefties one side, righties the other — and no batter is drawn when the feed does not report a side.

What changed for users

  • The zone finally reads at a glance the way a broadcast graphic does: you can see why a pitch at the knees is a strike and one at the eyes is not.
  • The figure mirrors to the real batting side of the hitter at the plate, straight from the same MLB feed as the scoreboard.
  • The silhouette sits behind the zone at low opacity and fades toward the frame edge, so pitch markers stay the loudest thing on the chart.

Release notes

  • Pitch locator: a true-proportion batter silhouette stands beside the zone, on the correct side of the plate for the hitter actually up.
  • The figure is drawn only when the MLB feed reports the batting side — no side, no batter.
  • The silhouette sits at low opacity behind the zone and fades toward the frame edge so pitch markers stay dominant.
P-26.08.032 · Live Games

The at-bat, the way TV shows it

The live page opens on the batter and pitcher face to face — headshots, their real lines from tonight's game, and the count big enough to read across the room. New pitches and batted balls animate in with real spring physics; everything already on screen holds still.

What changed for users

  • Batter versus pitcher leads the at-bat: faces, tonight's actual lines — 2-4 with a homer, 5.1 innings with 87 pitches — and the ball-strike count with the outs.
  • A new ball in play draws its flight from the plate and lands with a real bounce; a home run flares. Nothing already on screen moves, so motion always means something just happened.
  • Every panel opens with one plain sentence saying what you are looking at — no chart needs decoding.
  • Turn on Reduce Motion and everything simply appears, already settled.

Release notes

  • At-the-plate matchup card with official headshots, game box lines, and the live count.
  • Entrance animation for new pitches, tracers, and landing balls; spring easing where the browser supports it.
  • Plain-language intros on the pitch tunnel, locator, and spray chart.
  • Pitcher lines now carry pitch count, walks, hits, and earned runs from the boxscore.
P-26.08.031 · Live Games

The live page watches the game with you

The live game page now follows the game the way a broadcast does — the at-bat first, the plays right under it, the meaning after — and the instruments got real paint: a lit pitch corridor, a park with grass and clay, and pitches you can follow as a thrown sequence.

What changed for users

  • The at-bat in progress leads the page. What just happened sits right beneath it, not at the bottom.
  • Before first pitch the matchup preview leads; once the game starts it steps aside for the baseball.
  • The pitch tunnel is a lit corridor now — real ball spheres with shadows on the ground, a glass strike zone, and tails that stretch with velocity, so a 98 mph fastball feels different from a 78 mph curve.
  • The strike zone shows the batter actually standing in the box, on the side they really hit from, and pitches connect 1-2-3 as a sequence.
  • The spray chart is a park — grass, infield clay, warning track, distance arcs — with each ball's flight traced from the plate to where it landed, bowing with its measured launch angle.
  • The page refreshes every 15 seconds while the game is live, inside the official feed's own suggested pace.

Release notes

  • Live game page reordered: at the plate, what just happened, what it means, the game so far.
  • Pitch tunnel, locator, and spray chart repainted; pitch-family legend added.
  • Batter silhouette from the measured batting side; no side reported, no figure drawn.
  • Auto-refresh: 15s live, 45s otherwise.

The board fits in your hand

The decision board no longer scrolls sideways on a phone, tablets stop being handed a desktop table through a slot, and the iPhone app picks up the week's intelligence: Posterior Live on the game desk, player faces on the rows, and every graded slate's recap.

What changed for users

  • On a phone, the board holds still — the section rail no longer pushes the whole page into sideways scroll, and the blank band under the header is gone.
  • A tablet held upright gets stacked pick cards it can read instead of a desktop table it has to drag.
  • On iPhone, a live game desk shows what moved Posterior's number, on what evidence, and what it is watching next — from readings taken during that game, or a plain statement that none exist.
  • Decision rows on iPhone carry the player's face, and the morning recap opens any graded slate — a losing night as easily as a winning one.
  • Probability gaps read the same on every surface now, phone included.
  • Desktop is untouched.

Release notes

  • Section rail, masthead, and pick tables reflow below desktop widths; touch targets meet the 44px floor.
  • iPhone game desk gains Posterior Live with freshness labelling.
  • iPhone recap gains a graded-slate date rail with an honest missing-slate notice.
  • Official headshots beside iPhone Decision rows.
  • The next app build carries the iPhone changes.

Ask can show you what moved

During a live game you can ask why Posterior's number moved, and get an answer built from readings actually taken during that game — or a straight admission that no reading exists.

What changed for users

  • Ask about a game in progress and it can tell you what changed, how far the number moved, and what it is watching next.
  • If Posterior took no readings on that game, Ask says so instead of working an answer backwards from the score.
  • A movement is never dressed up as a pick. It is what the model saw, not a reason to bet.
  • Tonight's free pick shows the player, not just their name.
  • A probability gap is written the same way everywhere now, and a card no longer rounds one number two different ways in two places.

Release notes

  • Live-game questions carry Posterior's captured movement, recent changes, and what it is watching.
  • A game with no captured probability is stated as such.
  • Official player headshots on the public pick.
  • One wording for probability gaps and Action Windows across the product.

Every graded slate gets its own page

A day the model lost is now as easy to open as one it won. Each morning recap has a permanent address, the pick ledger links straight to it, and the track record page returns real numbers instead of stalling and then showing an empty ledger.

What changed for users

  • Every graded slate has its own recap link you can save, send, or come back to.
  • The pick ledger points at that morning's recap, so you can follow one night from the published price to the result to the write-up.
  • Ask for a date Posterior never graded and it says so, instead of quietly showing you a different night's numbers under that heading.
  • The track record page returns the real ledger. It used to sit for a minute and a half and then show zeros where the numbers should be. It is still slower than we want it — that work is not finished.
  • One probability now reads the same everywhere on a card. The headline said 64% while the sentence under it said 63.8%.

Release notes

  • /mlb/recap accepts a date and pins the page to that slate; each prior day carries a permalink.
  • The pick ledger links its yesterday line into that morning's recap.
  • Track record reads are bounded and report a missing ledger honestly.
  • Probability gaps are written one way across the product.

The desk stops guessing, and the live board says what moved

The track record page could hang for a minute and a half and then show a season that looked like zero. It now answers inside a budget and says when a reading is missing. Live games get a board that ranks where the league just moved.

What changed for users

  • The track record page answers quickly. When a reading does not arrive, it says the ledger is unavailable instead of printing a 0% season over the gap.
  • Live games are ranked by what actually moved, with the reason each one is on the list — built only from readings taken during that game.
  • A game we have no readings for never appears on that board. It stays empty rather than filling itself in.
  • Player faces appear beside the rows on the desk, so a long list of props is something you scan instead of read.
  • Labels across the desk now come from one small set of sizes rather than twenty-five.

Release notes

  • Track record answers within a bounded read and reports a missing ledger honestly.
  • New Right now board on Live for members: the live slate ranked by captured movement.
  • Official player headshots as a visual index in the Decision lists.
  • One shared label scale and one figure treatment across the newer desk surfaces.

One slate, counted the same way everywhere

The board, tonight's card, and the Today desk were each counting a different set of contracts and all calling it “assessed”. Every count now says which set it came from, and a board Posterior could not finish reading says so instead of reporting an empty market.

What changed for users

  • Each slate total names the group it counted, so the number on the board and the number on Today can no longer look like the same figure disagreeing with itself.
  • When a read comes back short, the desk says the board is incomplete and how many lines were left out — it no longer reports that as Posterior finding nothing worth playing.
  • A line Posterior could not match to a player is marked as unfinished work, not as a contract it looked at and rejected.
  • Members open Today and get their desk. No sign-in banner, no subscribe button, no locked rows they already pay for.
  • Rows explain themselves in plain English. The internal code is still there, one tap down, for anyone who wants it.
  • Live games get a Posterior Live panel: what changed, how far the number moved, and what Posterior is watching next — built only from readings actually taken during the game.
  • On a phone, Today, Board, Live, and Record sit at the bottom of the screen where your thumb already is.

Release notes

  • Slate counts carry their scope; the desk headline reads Board incomplete when coverage is broken.
  • Signed-in members no longer see paywall messaging on /today.
  • Price → Action Window → Receipt renders from one shared component across the desk.
  • Evidence is labelled LIVE, CURRENT, DELAYED, CACHED, ARCHIVED, or DEGRADED.
  • Posterior Live on the game page; a persistent bottom navigation on phones.
  • The Posterior Record and My Ledger are now two clearly separate destinations.

The desk sits in the middle again

On a wide screen, Posterior is still full-bleed in the background. The board, the homepage, and the rest of the desk sit in the old centered column instead of stretching to the edges.

What changed for users

  • A desktop monitor shows photography and atmosphere to the edges, with tonight’s board and copy in a readable middle column.
  • Phones are unchanged. They already used the full width of the hand.
  • Every product page shares that same desktop measure — not a squeezed homepage and a stretched board.

Release notes

  • Desktop content is centered. Page backgrounds still go edge to edge.
  • The living homepage masthead and hero copy use the same desktop column as the rest of the site.
  • Mobile layout is not capped.

Paying members land on tonight’s board at /mlb. Tonight’s Card is still a page you can open. It no longer intercepts the desk.

  • Tonight’s Card remains at /mlb/card if you want the compact readout.
  • Diagnostic lab blocks on that board stay limited to the owner desk.

Release notes

  • Signing in no longer sends you from /mlb to /mlb/card.

Your account is a desk again

The member page is a press credential and a ledger, not a settings dump. Complimentary Pro reads as complimentary. Followed clubs are chips you can tap, not a scrolling box of names.

What changed for users

  • Open Account and see your name, club, and tier — not your email set in display italic.
  • Complimentary access no longer pretends there is a card on file.
  • The phone layout stacks the same credential instead of squeezing the old two-column masthead.

Release notes

  • Account leads with a member pass: handle or name, club stamp, ledger strip, then the rest of the desk.
  • Complimentary Pro shows the through-date and hides the Stripe portal.
  • Followed clubs are chips. The old fake masthead and icon grids are gone.

The first screen tells the truth

Posterior now leads with the public ledger, including the losses. When tonight's board publishes and nothing qualifies, the desk says so instead of asking you to subscribe to an empty slate.

What changed for users

  • A first visit sees the MLB prop desk, the public W-L, and what to open next.
  • On nights with no public rec, you can still see that the board passed and ask for one email when one qualifies.
  • Calibration stays visible without a subscription. Live names still sit behind Pro.

Release notes

  • Homepage first screen: public ledger, today's desk, the CSV, and methodology. No search-as-hero and no ticket preview.
  • Today's desk no longer asks you to subscribe to reveal a board that did not qualify.
  • Methodology and accuracy share the live season record. Calibration is public; live picks stay Pro.
P-26.08.021 · Platform

The phone homepage gets the same living atmosphere

Phones no longer open a status dashboard. The mobile landing now leads with photography, search, and the baseball day — composed for a hand, not squeezed from a monitor.

What changed for users

  • The first screen on a phone is the living engine: a photograph, the same headline, and search.
  • Games, your club, players, and a Decision example follow as stacked, swipeable cards.
  • Desktop stays the wide desk. The two compositions remain separate.

Release notes

  • Mobile hero uses regional and campaign photography with the living headline and search.
  • Today’s games and player cards scroll sideways. Club, Decisions, access, and the public record stack below.
  • The old four-cell status board is no longer the first thing on the phone homepage.
P-26.08.020 · Play

The night scorecard.

Play now looks like a game you mark in ink. Two-sided calls sit on a night scorecard. Career rank, XP, missions, club clash, and today-month-season boards live on the same desk. Your public handle is a baseball resume: streak, perfect cards, and what you have actually earned.

What changed for users

  • Open Play and stamp a side on every open call. The scoreboard waits on the box score.
  • A losing card still moves XP and missions. Weekly club clash and period boards are ranks until three qualified players land.
  • Open a public handle to see streak, perfect cards, and earned marks — not a follow count pretending to be a career.

Release notes

  • Play is a copper-on-ink scorecard. Call buttons are the product. Handle claim sits after the card.
  • Boards cover today, this week, this month, and the season. Challenges you are in list on Play.
  • Public resumes show career rank, XP, streaks, perfect cards, and achievement titles when they exist.
P-26.08.019 · Play

Play is a game. Pick a side.

Today Card is no longer a printed sheet you stamp. You pick who wins, hit or no hit, six Ks or not, a run in the first or not. Each call locks at that games first pitch, so a late afternoon still has baseball left. Points are the score. XP and a baseball rank keep you moving even when the card goes 1-for-5.

What changed for users

  • Open Play on the web or iPhone and choose a side on every open call. Lock those picks. The box score grades them.
  • A 1-for-5 night still pays XP. Missions, achievements, club week, and a club clash sit on the same desk as the card.
  • Harder calls are worth more points than a moneyline. That is game difficulty, not a sportsbook price.

Release notes

  • Each call is a two-sided question. There is no silent lock of a printed winner.
  • Calls lock per game at first pitch. Remaining night games stay open after an afternoon starter.
  • Play shows career rank, XP, daily and weekly missions, earned achievements, and a same-division club clash when another club has played.

Play lands on iPhone

The iPhone app now has Play: lock the printed calls, watch them grade, and keep a handle other fans can find. Winter still prints a Hot Stove or Spring card when the regular-season slate is gone.

  • Claim a public handle from Play or Account so other fans can open your resume and follow you.

Desktop goes full-width. Phones get their own desk.

The living homepage no longer squeezes a wide desk onto a phone. Large screens use the full viewport. Phones and tablets open the mobile desk instead.

What changed for users

  • On a computer, Posterior uses the full screen: photography, games, and the Decision example sit in a wide composition.
  • On a phone, the homepage is a separate desk with its own navigation, status strip, and stacked sections — not a shrunk desktop.
  • The hero still follows region and favorite club on desktop. Mobile keeps the dedicated Posterior desk.

Release notes

  • Desktop layout is full-width with the existing living sections.
  • Below 1024 pixels, the mobile homepage desk and mobile nav take over.

Play keeps score — and winter still has a card

Play now opens as a session. Lock the printed calls, watch them grade, climb your club week, and come back tomorrow. When the regular-season slate is gone, Posterior prints a Hot Stove or Spring card from resolvable baseball questions. It will not invent rumor to fill five boxes.

What changed for users

  • The Play desk leads with your card: live, locked, graded, or perfect, plus club rank and streak when you have them.
  • A follow, a graded card, a settled challenge, or an unlock lands on Play and Fan Radar as a real object you can open.

  • Open Play to lock the printed calls, then see Your Card with live calls, club week rank, and streak.
  • My Baseball Fan Radar includes card grades, follows, challenges, and unlocks that link to resumes and receipts.

What changed for users

  • The hero still follows your club and region. National visitors keep the shared backplate.
  • Wide screens show the sourced game photography and club marks already in the product.
  • The Ticket Market again carries the official MLB mark behind the price desk.

Claim a handle you can actually open, and put a face on it

Handles on arguments, club challenges, and a public resume you control

A baseball identity can now carry a bio, privacy, and block/mute/report. Clubhouse arguments can show a claimed handle. Today's Card can be an async challenge. Weekly boards include your division, and a club Clubhouse can show people to follow without inventing a crowd.

What changed for users

  • Fans can follow, mute, or report a public resume, and keep bets off that resume unless they opt in to a self-reported record.
  • A claimed handle can appear on a Clubhouse argument or a public roster, never as an account id.
  • Today's Card can be challenged asynchronously. No cash, no point transfer, box-score grades only.

  • Public profiles include block, mute, and report.

P-26.08.011 · Decisions

The board keeps 1+ hits and sits out losing strikeout overs

Tonight's official board had been filling with pitcher strikeout overs while 1+ hit decisions stayed in the lab. Posterior now publishes 1+ hits from live sportsbook consensus, and parks strikeout overs that have been losing on the public record until that segment earns its way back.

What changed for users

  • 1+ hit decisions can appear on the official board again when they clear price, lineup, and edge gates.
  • Pitcher strikeout overs stay on the diagnostic record instead of being sold as official plays while that segment is losing.
  • The public ledger still shows every settled result, including the strikeout overs that are no longer recommended.

Release notes

  • The Decision board prefers 1+ hits when a live two-way sportsbook price exists.
  • Strikeout overs remain visible as research rows and still grade after the game; they are not official recommendations until the segment recovers.
  • A 1+ hit that does not beat the live consensus, or that lacks a confirmed lineup, still does not become a recommendation.

  • Clubhouse calls stay attached to the choice you made — including revisions, reality outcomes, and sealed receipts when they exist.

  • Open My Baseball from the signed-in navigation to see My Club, My Calls, My GM Desk, My Players, and Fan Radar.
  • My Calls separates open calls, calls awaiting reality, and resolved calls without pretending every baseball debate has a universal win or loss.
  • My GM Desk keeps active scenarios and marks a scenario for review only when current sourced roster reality makes a saved move no longer fully achievable.
  • Changing your Primary Club continues to synchronize the established desk preference with Clubhouse affiliation, while additional club follows remain optional.
  • My Baseball starts honestly when your history is empty: make a first call, follow a player, or build a roster scenario to give Posterior something personal to remember.

The homepage becomes one connected MLB desk

Posterior now introduces the baseball day, fan participation, club context, player discovery, and Decision intelligence in a deliberate sequence — with each section given its own visual job.

What changed for users

  • Fans can discover live MLB context, the Clubhouse, and their club before reaching Posterior's advanced Decision layer.
  • The homepage is shorter and clearer on mobile because repeated Decision explanations and duplicate receipt presentations are gone.
  • Existing Posterior imagery remains, but action photography, player identity, club identity, proof, and device visuals no longer compete for the same job.

Release notes

  • Posterior Decisions owns the detailed Price-to-Receipt example; Public Proof now concentrates on the aggregate ledger and calibration record.
  • Ticket Market, Access, Apple ecosystem, Public Proof, and the Posterior system follow a clean numbered sequence.

Moneyline joins the board — with honest anchors
