How do I take my turn?

Answered counted as answered

Depending on the phase of the game, taking a turn involves different actions: **In the Auction Power Plants phase:** 1. The player may offer a power plant from the current market for auction [1]. 2. If a player does not want to offer a power plant for auction, they must opt out, which means they cannot bid in later auctions during this phase and will not get a new power plant this round [2]. 3. Players may bid on power plants; if a player buys a power plant, they cannot bid in another auction in the same round, nor can they offer a plant at auction [1]. 4. When the auctioning player wins the auction and buys the power plant, the next player in turn order takes their turn (if they have not already purchased a power plant this round) [1]. 5. If a player other than the player who started the auction wins, the auctioning player may choose to auction a different power plant from the current market or pass [1]. **In the Buy Resources phase:** 1. Players may buy matching resources for their power plants as long as there is still storage space [2]. 2. Players may not buy resources that their current power plants cannot use [2]. 3. The player purchases resource tokens from the spaces of the resource market, paying the price shown on the upper right of each resource space to the bank [2][3]. 4. After purchasing, the player moves their house on the player order track to the same numbered space on the bottom row [2][3]. **In the phase for increasing electricity networks:** 1. A player may connect any number of new cities during their turn, as long as they pay all building and connecting costs [4]. 2. All subsequent cities added to a network must connect to at least one city already in that player's network (with one of their houses) [4][3]. 3. When connecting to a new city, the player chooses the cheapest connection(s) between one of the cities in their network and the new city and pays the total of connecting costs and the cheapest available building cost to the bank [4]. 4. After connecting all desired cities, the player moves their house on the player order track to the same numbered space on the bottom row [4].

retrieval — what the search arm returned

score = the fused retrieval score (reciprocal-rank fusion over the search arms) — NOT a cosine similarity. How many arms fused this ruling was NOT RECORDED (it predates the boost trail, ran on the path that stored none, or stored one that could not be read), and the ceiling depends on that count (ceiling = arms/(k+1) at k=60): 2 arms top out at 0.03279; 3 arms top out at 0.04918. So a score above 0.03279 here is not an anomaly: it is arithmetic proof a boost arm voted, and the measured band 0.016–0.033 (taken on two-arm asks) is what does not apply. A chunk only one arm ranked highly lands near 0.016 (that one arm's #1 vote), so 0.03 here is an excellent hit, not a 3% match.

per-arm ranks (the rank each search arm gave a chunk): NOT DISCLOSED by the gateway. Fusion happens gateway-side and only the FUSED score crosses the wire, so rulesage cannot show them without a gateway change. The rank column below is the FUSED rank (position in the returned list), which is real.

token count per chunk: NOT DISCLOSED — chunk token counts are not reported on the ask path. The character counts below are of the bounded snippet/quote rulesage actually received — a real measurement of what we hold, never an estimate of the chunk.

generation — timing and the path taken

timing split: retrieval 208 ms · first delta n/a · total 9977 ms (retrieval and first-delta both measured from the START of gateway work, so first-delta INCLUDES retrieval — do not subtract)
full breakdown: queued 0 ms · retrieval 208 ms · ask 9758 ms · gateway work 9977 ms · total 9977 ms
live seat (read from the running child): answering — gemma4:26b think:false · num_ctx 32768 (live-verified 54s ago)
stream path: not recorded — this ruling predates the stream-path column (V41)
watchdog: first-token watchdog: 30s per arming window (rulesage.table.first-token-watchdog-seconds), re-armed once by the passages frame — so the worst case before a reader falls back to polling is 60s. Whether it actually fired is a BROWSER-side decision that never reaches the server, so it is not recorded here. The stream path above is the server's half of that story: whether a delta was emitted at all.
num_ctx · think posture: both are the CHILD's settings, not rulesage's, and no ask reply carries them — an answer never states which context window or think posture produced it. The live-seat line above reads them from the running child instead, where the gateway can answer for itself; it describes the child NOW, not this ask.

abstain rationale (n/a — this ruling answered): answered — no abstain rationale applies

setup-shape — why the checklist band did or didn't render

decision: NOT_SETUP_SHAPED — no setup-shape pattern matched this question

errata registry — what the gate above had to match against

this game registers NO errata cards (edition 25), so "no registered errata card matched" above could never have matched one

Errata scope: the gate above matched this ruling's own edition only. When an ask also reads an expansion, that expansion's own registered errata cards stay outside the match — a stated phase-1 limitation, not a failed lookup.
