Problem

  • Upkeep was withdrawn once, when a node was activated. The node could then run for any number of cycles without paying again.
  • Deactivating refunded the full upkeep once for every input taken, so switching off a long cycle could pay back more than was charged.
  • The SimpleFactions ledger showed a daily Nodes line that counted inactive nodes and left out the over-capacity multiplier.

Change

  • Node.getDailyUpkeep() returns upkeep × costIncrease. That is the same "Total Upkeep" the node GUI already showed, now labelled d/day.
  • NodeManager.getTotalUpkeep() counts only active nodes. SimpleFactions charges this amount at every new day (companion PR).
  • Activation no longer withdraws. It still requires the guild to afford one day of upkeep.
  • A deactivation refund now returns only the cycle's inputs, not upkeep.
  • Abuse logging. Each manual activation and deactivation is logged with player, guild, node, location, daily upkeep and time until the new day. It goes to the console and to plugins/Dowsing/node-toggles.log. A toggle within 1 hour of the new day is logged at WARNING, so switching a node off over the new day to skip upkeep is easy to spot.

Behaviour change: guilds over their node capacity now pay the multiplied upkeep that the GUI advertised. Previously they paid the raw amount.

Deploy

Ship together with the SimpleFactions companion PR.

Testing

  • mvn package passes, with new tests for the upkeep total and the log's duration format.
  • Loaded on TFMCDev and checked there.

Summary by CodeRabbit

  • New Features

    • Active nodes incur upkeep at the start of each new day. Daily upkeep reflects the node’s cost increase and is rounded to two decimal places.
    • Node details show upkeep with a clear per-day rate.
    • Active-node details clarify that current-cycle inputs are refunded when deactivating, and that upkeep is charged daily while the node is active.
  • Bug Fixes

    • Upkeep totals include only active nodes owned by the relevant guild.
    • Activation checks that the guild can cover daily upkeep without charging it immediately. Deactivation no longer refunds upkeep as though it were a cycle cost.

Activation used to withdraw upkeep once and deactivation refunded it once
per input taken, so a long cycle could be switched off for more than was
paid. Upkeep is now charged by the SimpleFactions daily settlement for
each active node, including the over-capacity multiplier the GUI already
showed, and deactivation refunds only the inputs.

Manual activations and deactivations are logged to the console and to
node-toggles.log with the time left until the new day, as a warning within
an hour of it, so switching nodes off over the new day can be spotted.

📝 Walkthrough

Walkthrough

Node upkeep calculations now use a rounded daily amount for activation checks, guild totals, and displays. Activation no longer withdraws upkeep, and refunds no longer deposit upkeep. Successful manual activations and active-node deactivations are recorded in a timestamped log.

Node.getDailyUpkeep() calculates and rounds daily upkeep to two decimal places. Cost increases use guild node count and capacity when available. Activation checks and guild totals use daily upkeep; activation no longer withdraws upkeep, and refunds no longer deposit it. Displays identify the daily rate and active-node lore states when upkeep is charged.

NodeManager records successful activations and deactivations of active nodes. NodeToggleLog records event details, selects warning or info logging based on time until the new day, and appends entries to node-toggles.log. Tests cover duration formatting.

Merge Risk: ⚪ Minimal · up to 50d2f

Capacity purchases are reflected in subsequent upkeep totals. No identified issue remains that should block merging after normal checks.

Security Architecture Review

Security architecture risk: 🟡 Moderate · up to 50d2f

Guild members may be able to run nodes without paying the intended upkeep. The new toggle log helps identify some activity but does not collect or reserve payment. The companion billing behavior needs verification before the two changes are deployed together.

Retained concerns

  • Medium · security · inferred: Removing the activation charge leaves upkeep eligibility dependent on active state at daily settlement. A guild member can operate a node and deactivate it before that snapshot; the new log records toggles but does not enforce payment. Actual charge timing remains dependent on the companion system.
  • Medium · security · observed: Each activation checks the same available bank balance against one node's upkeep without debiting, reserving, or checking the aggregate active obligation. Multiple nodes can therefore become active when their combined daily upkeep exceeds that balance; the companion system's response to an unpaid charge is unknown.
Security review details

Security Blast Radius

  • inferred — The apparent independently attackable scope is upkeep for a guild's own nodes and bank, rather than another guild's nodes: the observed player path checks matching guild ownership, while the total filters by guild ID.

Security Findings and Attack Paths

  • inferred — A guild member able to toggle a node can obtain production before settlement and remove the node from the active-only upkeep total before rollover. Whether the companion later reconciles that usage is unknown.

Trust Boundaries and Controls

  • observed — The inventory handler enforces guild ownership or administrator permission, and Node.activate retains bank, resource, biome, and prerequisite checks. Those checks do not reserve upkeep or establish that daily collection succeeded.

Resilience and Maintainability Implications

  • observed — A toggle-log file write failure is reported to the server logger without reversing the toggle. The audit file is therefore not a durable prerequisite for changing node state.

Hardening Proposals

  • proposed — Verify the companion settlement's snapshot, insufficient-funds, and rollover semantics; consider enforcing a charge or reservation for the billable interval rather than relying on toggle warnings to detect missed upkeep.

A rabbit checks the daily rate,
Then logs the toggles, small and great.
The node wakes up; the record grows,
While rounded upkeep neatly shows.
At dawn, the charges start anew,
And carrots wait for review.

Refresh upkeep multipliers when guild capacity changes.

If a guild buys capacity while its nodes are over capacity, purchaseCapacity() changes the capacity but does not update those nodes. getTotalUpkeep() then continues to return their old, higher daily charges until another action updates each node. Recalculate the affected nodes’ upkeep when capacity changes, before a daily settlement can read this total.

Comment thread src/main/java/net/tfminecraft/dowsing/objects/Node.java Outdated
Capacity changes when members join or capacity is bought, which does not
refresh every node, so the daily upkeep now uses the guild's current node
count and capacity. Round it to the cent with BigDecimal half-up.

Merging with admin bypass. I opened this pull request, so I cannot approve it, and CodeRabbit's changes-requested review is still the recorded decision even after 50d2fd9. That commit calculates the capacity multiplier when upkeep is charged and rounds to the cent. The later CodeRabbit pass reported no remaining comments.
