PM Time Tracker Bridge

What it is

PM Time Tracker Bridge connects Mission Control items to the Time Tracker -- a Time tab in the item card lets you start/stop timers and view logged time against any PM item, directly from the board.

Starting a timer from an item card creates a time entry linked to that PM item (pm_item_id on time_entries). The entry appears in both the item card's Time tab and the Time Tracker's Today timeline (with a PM item name chip).

Where to find it

In two places. On the board, an item card carries a Time tab where a timer is started and stopped and the logged time for that item is listed. In the Time Tracker, the same entry shows up on the Today timeline, tagged with a chip carrying the PM item's name.

How it behaves

All Time Tracker invariants are preserved:

• Single-running: starting a timer auto-stops any running entry (reuses the existing TIME_TRACKER_ENTRY_START channel, extended with optional pmItemId)
• Derive-once money: billable amounts are derived at read time using BigInt-exact multiply/divide (never stored per entry)
• Plugin isolation: the Mission Control plugin communicates only through window.__AMC_MISSION_CONTROL_SESSION__ bridge methods, never importing AMC modules directly

There are no dedicated settings; the feature requires both Mission Control and the Time Tracker to be enabled.

For agents

Two read-only channels were added (both in BLOCKED_CHANNELS for desktop-only):

• TIME_TRACKER_PM_ENTRIES -- list time entries for a PM item
• TIME_TRACKER_PM_TOTAL -- total time + billable amount for a PM item

Timer start/stop reuses the existing Time Tracker channels -- no new write channels were added.

Data model

Column	Type	Table	Purpose
pm_item_id	TEXT, nullable	time_entries	Links entry to a PM item
pm_item_name	TEXT, nullable	time_entries	Denormalized name for display

A filtered index (idx_time_entries_pm_item) covers non-null pm_item_id.

Settings: no dedicated settings. Requires missionControlEnabled and the Time Tracker to be enabled.

The time side of this bridge is documented in time-tracker.md, and the board side in mission-control.md -- the parent page. Because a timer is started from an item card, pm-my-work.md is often the quicker way to reach your own items. The full behavioural contract is recorded in pm-time-tracker-bridge-contract.md, and every other page in this library is listed in INDEX.md.
