Readiness

What this surface is

Readiness is the evaluation workspace for a target deck you already have. Its page header reads Readiness — “Bottlenecks, conflicts, chain analysis, and battle-log insights.”

Three tabs are exposed in the tab strip, each answering a different question: how does this deck stack up against another one, how do its interaction chains resolve, and what actually happened when you played it. A fourth view — conflicts — is reachable by deep-link only; see the note under Tabs.

Where to find it in the app

Sidebar → Strategy → Evaluation, which routes to /readiness. The nav label is “Evaluation”; the page title is “Readiness”. Both refer to this surface.

Target-deck selection

Readiness always operates on one deck at a time and picks it for you.

On a fresh load — a new tab, a reload, or a session in which you have not opened a deck in Deck Lab yet — the order is:

1. ?deck=<id> in the URL, if that deck is one of your target decks
2. the deck currently open in Deck Lab
3. the most recently updated target deck

Within a session, a deck already open in Deck Lab wins. Once you open a deck in Deck Lab, that choice is remembered for the rest of the browser session, and Readiness starts on it — ?deck= does not override it. So navigating to /readiness?deck=<other-id> after having opened a different deck in Deck Lab analyses the Deck Lab deck, not the one named in the URL.

Precaución

The Compare title can disagree with the analysed deck. The browser tab title is derived from ?deck=, but the analysis is run on the deck selected by the rule above. In the session case described above they are different decks, so the title names one deck while the panels show another. To be certain which deck you are looking at, reload the page with the ?deck= link — a fresh load honours the URL.

If you have no target decks, there is nothing to select and the tabs render empty. Create a deck in Deck Lab first.

Tabs

The default tab is Compare.

Tab	?tab=	What it shows
Compare	compare	Two decks side by side — see Compare
Chain Analysis	chain	How the deck’s interaction chains resolve
Battle Log	battle_log	Recorded duels, matchup notes, and the cards that mattered

Compare and Chain Analysis carry a view-mode toggle (list / thumbnail / gallery); Battle Log does not.

Precaución

Missing / bottleneck cards are not here. They moved to the Market surface on 2026-05-08. A /readiness?tab=bottlenecks link rewrites the address bar to /market?tab=bottlenecks, but the rewrite is not a navigation — Readiness stays mounted on its default Compare tab, and the corrected URL only reaches Market on the next load. Link to /market?tab=bottlenecks directly.

Precaución

A fourth tab exists but has no tab-bar entry. /readiness?tab=conflicts renders the conflicts panel — the same “conflicts” the page subtitle advertises. The tab strip lists only Compare, Chain Analysis and Battle Log, so the deep-link is the only way in. This is an underexposure gap, not a removed feature.

Compare deep-links

The Compare tab reads two parameters:

• ?deck=<id> — the baseline deck
• ?cmp=<id> — the deck to compare it against

Compare is the default tab, so /readiness?deck=<id>&cmp=<id> already renders the right content. The browser tab title, however, is gated on tab=compare being present explicitly: it resolves only for

/readiness?tab=compare&deck=<baseline-id>&cmp=<target-id>

which produces <baseline> vs <target> - Compare - DeckScope. Use that third parameter in anything you share, or the link lands under the generic app title and is unrecognisable in a tab strip.

A shared Compare link resolves its baseline reliably only on a fresh load — see Target-deck selection for the in-session case where a deck open in Deck Lab takes precedence over ?deck=.

Battle Log

Battle Log records real duels rather than simulations: match details, duel notes, and the cards that decided the game. Notes support card mentions — type / inside the comment composer to insert a card reference — and entries have a read-oriented preview mode separate from the edit mode.
