- Include item_key in StreamingObject#id so a LATEST item no longer collides with an explicit subscription to the same packet item - Fall back to removing by key in StreamingObjectCollection#remove since items are added as [key, item_key] but removed by key alone - Resolve LATEST in get_limits using the caller's scope, not $openc3_scope, and inline the single-use _get_item helper - Authorize the resolved packet in get_limits (Ruby and Python) instead of the literal LATEST, and upcase the names Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
- Key TargetModel item_map_cache by the scoped item_map_key instead of the target name so LATEST can't resolve against another scope's map - Clear the cache entry in test_cvt_model so the LATEST test no longer depends on test order Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
- override_tlm, normalize_tlm, enable_limits and disable_limits expand LATEST to every packet containing the item via _tlm_process_args_all_packets - set_limits and set_state_color accept LATEST and validate every packet before changing any so a failure can't partially apply - Authorize each expanded packet before making any change - Factor _tlm_extract_args and _tlm_resolve_packet_name out of _tlm_process_args (Ruby and Python) Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
- get_tlm_values with start_time queries every packet containing a LATEST item instead of the packet received most recently now - A point in time queries each candidate packet on its own since the ASOF JOIN only looks up other packets at the first packet's last row - A range puts regular items first so they drive the rows; a range of only LATEST items keeps using the packet received most recently now - Alias every tsdb_lookup column since QuestDB renames duplicate names across tables (VALUE_2), which broke decoding of the second one - Add a flatten option to tsdb_lookup and QuestDB integration specs Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
- Historical LATEST queries each candidate packet with the value type and limits that packet has; asking for a missing column (VALUE__F) failed the whole QuestDB query - get_tlm_available reports the best value type and limits across all LATEST packets instead of only the one received most recently - Factor _tlm_available_value_type out of get_tlm_available Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
- Streaming rejects LATEST for commands since the item to packet map only covers telemetry - Streaming skips LATEST packets the user can't access instead of failing the whole request, raising only if none are accessible - get_tlm, get_tlm_packet, get_tlm_buffer, get_tlm_cnt, get_packet_derived_items and wait_packet raise a clear LATEST error Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
- Both take a packet name directly rather than through _extract_target_packet_names so they missed the LATEST check; share it as _tlm_reject_latest (Ruby and Python) Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
- Python _tlm_available_value_type counted a DERIVED read conversion as CONVERTED, but Packet.decom writes no __C for it, so historical lookups queried a missing QuestDB column - Add Python and Ruby tests for a DERIVED item with a read conversion Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

What changed in this PR
7 important issues, 1 nit.
This PR expands consistent LATEST telemetry handling across Ruby, Python, QuestDB history, limits operations, and streaming.
Changes:
- Expands
LATESTacross candidate packets for writes, limits, and historical queries. - Adds scoped item-map caching and QuestDB column aliasing.
- Rejects
LATESTwhere a concrete packet is required and adds parity tests.

- Around line 761-767: Update the historical LATEST lookup in get_tlm_values to
exclude candidates whose QuestDB tables are missing before the range ASOF JOIN,

candidates can still return values. Suppress only the missing-table error; allow
unrelated query errors to propagate. Use the by_packet and CvtModel.tsdb_lookup
flow shown in the diff to locate the lookup logic.

The api docs spec reads every def as a public API, so the nested add helper in tlm_api.py failed the doc and Ruby/Python parity checks. Match the skip filters on file basename so a checkout path containing "stream" no longer drops every Python script file. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

Select historical packets from the requested range, not the live CVT.
When a range contains only LATEST items, this branch selects the packet received most recently now. If another candidate held the item during the requested range, the query omits that candidate’s history. If the selected packet has no QuestDB table, the query can fail instead of using a candidate with historical data. Filter candidates by existing tables and resolve the range from their historical timestamps. The matching Ruby path needs the same correction. (raw.githubusercontent.com)
Based on learnings, a runtime-added packet has no QuestDB table until its first row, and historical LATEST must exclude candidates without tables.

Keep range rows aligned across QuestDB shards.
When a regular item and a LATEST item belong to different shards, this query places the regular item first. QuestDB then queries each shard separately and merges rows by ordinal position, not packet time. A LATEST value from a later timestamp can therefore appear beside an earlier regular-item row. Align shard results by timestamp before selecting candidate values, or reject this mixed-shard range until it can be aligned. (raw.githubusercontent.com)

Restrict the fallback sweep to the requested item key.
An unknown explicit item pair must not remove other subscriptions. Do not restrict the fallback to key_only requests. A LATEST expansion can produce a different concrete object ID when the packet mapping changes, so an explicit-item removal can require the fallback. Match both source_key and item_key.

Update the fallback sweep in the object-removal logic to match both source_key
and item_key for explicit-item removals, so an unknown item pair cannot remove
other subscriptions. Preserve the broader source-level sweep for key_only
requests and retain the fallback for explicit-item removals when no exact object
is found.

Removing an explicit [key, item_key] pair that has no exact object now only sweeps objects with the same source_key and item_key, so an unknown pair can no longer drop other subscriptions on that key. Co-Authored-By: Claude <noreply@anthropic.com>
Build positions in _tlm_latest_history as a dict keyed by item index so ty no longer flags a possibly-None entry as not iterable. Co-Authored-By: Claude <noreply@anthropic.com>

284-290: 🚀 Performance & Scalability | 🔵 Trivial | 💤 Low valueRemove the redundant
LATESTresolver call.
_tlm_packet_namesandCvtModel.determine_latest_packet_for_itemuse the same packet map. The resolver always returns a member ofpacket_names, so the union adds nothing. The resolver also performs an unnecessary CVT read for every candidate.In Python, a candidate without current CVT values can raise before the existing
tryblock. This behavior is pre-existing, not introduced by this PR.♻️ Suggested change
