Possible missing 1-minute aggregates: MMM and HON (Stocks Basic)

Hello Massive Support,

We are investigating possible missing 1-minute stock aggregate bars on the
Stocks Basic plan.

Affected requests:

1. MMM โ€” missing 2026-08-04 13:58 UTC

The adjacent one-minute bars contain material activity:

• MMM 2026-08-04: 13:57 volume 9,099.618093 / 166 transactions;
  13:59 volume 2,825.923488 / 102 transactions.
• HON 2026-08-04: 13:57 volume 1,328.076841 / 62 transactions;
  13:59 volume 4,683.273666 / 100 transactions.
• HON 2026-08-03: 13:54 volume 5,205.521008 / 158 transactions;
  13:56 volume 4,564.955796 / 205 transactions.

Notably, MMM and HON are missing the same minute (2026-08-04 13:58 UTC),
which suggests a possible ingestion-side or symbol-partition issue rather
than two independent no-trade intervals.

HON appears in two of the three cases and underwent a spinoff and company-name
change effective 2026-06-29. Could post-corporate-action symbol mapping be
related to the repeated HON omissions?

We also checked the other 28 current Dow constituents at 13:58 UTC on
2026-08-04. All 28 had bars. Across those 28, the median 13:58 volume and
transaction-count ratios versus the mean of 13:57 and 13:59 were both
approximately 0.898, so we did not observe a market-wide collapse at that
timestamp.

For all three affected five-minute windows, the five-minute aggregate volume
exactly equals the sum of the four available one-minute bars.

Could you please confirm:

1. Did these intervals have zero qualifying trades because of trade-condition
   filtering, or do they represent an ingestion/data gap?
2. If this is an ingestion issue, is it known to be systematic, transient, or
   symbol-partition specific?
3. Are five-minute aggregates constructed from the same underlying base
   aggregates, or independently from qualifying trades?

Thank you.
