How do I take my turn?

Answered counted as answered

Depending on the phase of the game, taking a turn involves different actions: **During the Power Plant Auction Phase:** 1. If you are the auctioning player, you may offer a power plant from the current market for auction [1]. 2. If you do not want to offer a power plant for auction, you must opt out, which means you cannot bid in later auctions during this phase and will not get a new power plant this round [2]. 3. If you win an auction, you buy the power plant [1]. 4. If you are the auctioning player and someone else wins, you may choose to auction a different power plant or pass [1]. **During the Resource Purchasing Phase:** 1. Players may buy matching resources for their power plants from the resource market as long as there is storage space [2]. 2. You purchase resource tokens from the spaces of the resource market by paying the price shown on the upper right of each space to the bank [2][3]. 3. After purchasing, you move your house on the player order track to the same numbered space on the bottom row [2][3]. **During the Network Expansion Phase:** 1. You may connect to any number of new cities during your turn, provided you can pay for them [4][5]. 2. To build the first house in your network, choose an empty city in the contiguous playing zone and pay 10 Elektro [3]. 3. All subsequent cities added to your network must connect to at least one city already in your network [5][3]. 4. When connecting a new city, you choose the cheapest connection(s) between a city in your network and the new city and pay the total of the connecting costs and the available building cost (10, 15, or 20 Elektro) to the bank [5]. 5. After connecting all desired cities, move your house on the player order track to the same numbered space on the bottom row [5].

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 231 ms · first delta n/a · total 9529 ms (retrieval and first-delta both measured from the START of gateway work, so first-delta INCLUDES retrieval — do not subtract)

live seat (read from the running child): answering — gemma4:26b think:false · num_ctx 32768 (live-verified 43s 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.
