In `@Server/src/overseer/api.py`:
- Line 21: Update EventLedger query usage in the event-listing handler at
Server/src/overseer/api.py lines 21-21 to pass limit into a SQL-backed bounded
event query, avoiding full-ledger retrieval before slicing. Update the
pending-approvals handler at Server/src/overseer/api.py lines 34-37 to use the
ledger’s SQL-backed pending-approval query with team_id and limit, rather than
filtering all events in memory.
- Line 16: Protect the /events, /summaries, and /approvals route handlers in
Server/src/overseer/api.py with authentication and enforce authorization for the
requested team before applying any optional team_id filter. Reject
unauthenticated requests and prevent users from accessing data belonging to
teams they are not authorized to access, while preserving authorized responses.
- Line 17: Update the SQLite connection strategy used by EventLedger so
synchronous FastAPI handlers can safely access it from worker threads,
preserving the existing /events handler at Server/src/overseer/api.py lines
17-17, /summaries at lines 24-24, and /approvals at lines 28-28. Add an API
regression test constructing EventLedger with sqlite3.connect(":memory:") and
exercising these routes.
In `@Server/src/overseer/ledger.py`:
- Line 110: Update the timestamp handling in the ledger creation flow around
created_at so aware inputs are converted to UTC before isoformat() and naive
timestamps are rejected; preserve the existing UTC-now fallback when created_at
is absent.
- Around line 25-26: Update the ledger’s amount contract to use exact minor
units or a lossless decimal, persist that representation instead of SQLite REAL,
and make the summary aggregation currency-aware by grouping totals per currency
or applying explicitly recorded exchange rates. Apply these changes at
Server/src/overseer/ledger.py lines 25-26, 59-60, and 168-184, preserving
accurate revenue, cost, and profit calculations.
- Around line 168-169: Update the monetary aggregates in the ledger query to
include only events with requires_approval = 0 in both the revenue and costs SUM
conditions, preserving the existing category checks and COALESCE behavior.
- Around line 74-124: Update EventLedger.record to validate amount with
math.isfinite before creating or inserting the LedgerEvent, rejecting NaN and
infinite values while preserving the existing non-negative validation.
In `@Server/src/overseer/simulation.py`:
- Line 18: Validate model_cost and subscription_amount as nonnegative before
constructing events or calling ledger.record. Reject invalid amounts before any
ledger write so the ticket lifecycle cannot be partially committed.
In `@Server/src/overseer/teams/__init__.py`:
- Around line 17-24: Sort the entries in the __all__ declaration alphabetically,
including TEAM_SPECS and the other exported symbols, so the Ruff RUF022 check
passes.

Do not detach an unnamed in-memory database from the supplied connection.
When connection is sqlite3.connect(":memory:"), the else branch creates a separate database and connection.backup(self._connection) copies only the initial state. Later EventLedger.record() writes can diverge from writes made through connection, which splits ledger state.
Define connection ownership explicitly. Use a database path or connection factory if the ledger must own its connection. Otherwise, preserve the supplied connection.

Re: #1386 (comment) Accepted: the warning is not a configured CI gate, but the underlying coverage gap was real in the newly added overseer modules. Added concise docstrings to all touched functions and classes (100% AST coverage for Server/src/overseer); focused overseer tests pass (14 passed). |

Description
Adds a provider-neutral overseer foundation for tracking agent activity, revenue, costs, profit, and human approvals while keeping external integrations and irreversible actions out of the initial implementation.
