Summary

  • New API method logLockChange(String user, Location location, String lockState, boolean staffOverride); API version 13 → 14.
  • A lock change is stored as a normal interaction row (action 2) under the real player name, with [coreprotect:lock, state, staffOverride] in the row's meta. Rollback already skips interactions, purge treats them like clicks, and u:<player> finds them.
  • /co lookup and the left-click block inspector render these rows as Steve set chest lock to Private. or Admin set chest lock to Public (staff override).
  • The block inspector now includes interaction rows with metadata (action=2 AND meta IS NOT NULL). Plain clicks have no metadata, so block history is otherwise unchanged.
  • New phrases LOOKUP_LOCK_CHANGE and LOOKUP_LOCK_CHANGE_STAFF (English default; other languages fall back to it).

Thievery will call this when a player cycles a container, display or furniture lock.

Test plan

There is no test suite in this repo, so I checked it on a local Paper 1.21.10 server with a small test plugin calling the API and a protocol bot as the player:

  • SQLite (what Main and Dev use): left-click inspector, /co lookup u:Steve, /co lookup a:click r:10 and /co l 1:10 all show the new lines; a plain logInteraction still reads "clicked chest" and stays out of the inspector
  • Backdated rows show as 1.00/d ago
  • /co rollback u:Steve,Admin t:2d r:10 modifies 0 blocks and the lock entries remain
  • DuckDB: inspector and u:Admin lookup render the same lines
  • Empty lock state is rejected (logLockChange returns false)

Summary by CodeRabbit

  • New Features
    • Added API support for recording lock-state changes, including changes made with a staff override.
    • Block lookups now display lock-state changes and indicate when a staff override was used. Plain clicks remain excluded.

Add CoreProtectAPI.logLockChange(user, location, lockState, staffOverride)
and bump the API version to 14. A lock change is stored as an ordinary
interaction row under the real player name, with the new state in the
row's block metadata, so rollback, purge and u:<player> lookups treat
it like any other click.

Lookups and the block inspector show these rows as
"Steve set chest lock to Private." or, for staff overrides,
"Admin set chest lock to Public (staff override)." Left-click inspection
of a block now includes its lock changes; plain clicks stay out of
block history because they have no metadata.

📝 Walkthrough

Walkthrough

The API now queues lock changes with metadata for persistence. Block and standard lookup paths parse that metadata and display the lock state with a regular or staff-override message.

Changes

Lock Change Logging and Lookup

Layer / File(s) Summary
Lock-change data and API entry point
src/main/java/net/tfminecraft/coreprotect/model/action/LockChange.java, src/main/java/net/tfminecraft/coreprotect/CoreProtectAPI.java, src/main/java/net/tfminecraft/coreprotect/consumer/Queue.java
Adds lock-state and staff-override metadata parsing and serialization. Adds logLockChange, which validates its inputs and returns the queue result.
Queue and persist lock changes
src/main/java/net/tfminecraft/coreprotect/consumer/process/*, src/main/java/net/tfminecraft/coreprotect/database/logger/PlayerInteractLogger.java
Adds the LOCK_CHANGE queue action and consumer dispatch. The interaction logger inserts lock-change metadata when it is present.
Lookup queries and lock-change messages
src/main/java/net/tfminecraft/coreprotect/database/lookup/BlockLookup.java, src/main/java/net/tfminecraft/coreprotect/command/lookup/StandardLookupThread.java, src/main/java/net/tfminecraft/coreprotect/language/Phrase.java, src/main/java/net/tfminecraft/coreprotect/language/Language.java, lang/en.yml
Lookup paths parse lock-change metadata and select the regular or staff-override phrase. English defaults are added for both messages.

Merge Risk: ⚪ Minimal · up to 43a39

Lock-change logging and lookup have no confirmed merge-blocking issue in the inspected paths.

Security Architecture Review

Security architecture risk: 🟡 Moderate · up to 7e25c

The new audit records rely on other plugins to supply accurate player and staff-override information. The API can also report that a record was queued when logging has stopped, so these records should not yet be treated as a guaranteed account of lock changes.

Retained concerns

  • Medium · security · observed: Plugins can submit lock-change records for any supplied player and assert a staff override without identity or staff-authority verification at the new API boundary. The staff-override assertion is subsequently shown as audit history; the existing interaction API already permits caller-supplied player names, but not this new assertion.
  • Medium · reliability · observed: The new API documents success as a queued lock change, but returns true even when the persistence-halted path declines to publish it. A caller relying on that result can believe a security-relevant change was recorded when no record was accepted.
Security review details

Security Blast Radius

  • inferred — The independently established caller boundary is another plugin obtaining the public API, not a player command in this repository. Such a caller can choose the recorded name, location, state, and staff-override flag; deployment restrictions on installed plugins were not established.

Security Findings and Attack Paths

  • inferred — A plugin that supplies false attribution can create a lock-history line claiming a staff override. This does not establish that an ordinary player can call the API or that a deployed plugin forwards untrusted player input.

Trust Boundaries and Controls

  • observed — The new API checks availability, non-empty user and lock state, and location presence, but does not establish the actor's identity or authority for staffOverride. The older interaction API uses the same availability and user/location checks, limiting the newly expanded trust claim to lock-specific information.

Resilience and Maintainability Implications

  • observed — A halted consumer can reject publication without the rejection reaching the new API result. The interaction writer can also omit an event following its existing blacklist, cancellation, or invalid-block checks, so API success is not a durability guarantee.

Hardening Proposals

  • proposed — Define which caller verifies the actor and staff authority, and distinguish queue acceptance from eventual persistence in the API contract. Constrain or safely render caller-provided lock-state text before displaying it in staff lookups; the visible path inserts that text into formatted output, but its upstream player controllability was not established.

A rabbit logs a lock-state change,
With metadata queued in its range.
A lookup reads the state,
Staff overrides get their own plate,
And plain clicks stay outside the exchange.
