…aho-mqtt-cpp The Nix environment provides paho-mqtt-cpp as a shared-only library and does not include libmeos. Four changes make the build pass: - flake.nix: add stock paho-mqtt-c + paho-mqtt-cpp to baseThirdPartyDeps; pass -DNES_ENABLE_MEOS=OFF in both defaultPackage and devShell cmakeFlags. - nes-plugins/CMakeLists.txt: introduce NES_ENABLE_MQTT and NES_ENABLE_MEOS options that gate the respective plugin subdirectories via activate_optional_plugin(). - nes-plugins/Sources/MQTTSource, nes-plugins/Sinks/MQTTSink: select PahoMqttCpp::paho-mqttpp3-static when available, fall back to the shared PahoMqttCpp::paho-mqttpp3 target (Nix only ships the shared variant). - nes-physical-operators: gate all MEOS-specific add_plugin calls and the nes-meos link behind if(NES_ENABLE_MEOS) in three CMakeLists files (top-level, Functions/Meos, Aggregation/Function/Meos). - CMakeLists.txt (root): declare option(NES_ENABLE_MEOS) and add_compile_definitions(NES_ENABLE_MEOS) before the nes-* subdirectory loop so the preprocessor symbol is visible to all sibling components. - nes-query-optimizer/LowerToPhysicalWindowedAggregation.cpp: guard the TemporalSequenceAggregationPhysicalFunction include and instantiation with #ifdef NES_ENABLE_MEOS so the translation unit compiles and links when MEOS is disabled.

Superseded by the master-derivation deliverable. The pin artifacts here (tools/pin/compose-order.txt, tools/regen-from-pin.sh) are obsolete: pins are no longer used — the surface derives directly from MobilityDB master via the MEOS-API catalog. The generation policy (family-organized, catalog-derived, zero hand-written surface) is realized and documented by the committed generator (#185: tools/codegen + README) and enforced by the drift-guard CI (#186). Closing; reopen if a top-level GENERATION.md is wanted, which would then reference master rather than a pin. |

Add tools/pin/compose-order.txt (the canonical fold manifest of the ~50 open codegen-wave PRs from the live DAG: generator infra MobilityDB#170 first, then the per-family NES operator waves W105-W149, then the -22a verify/regenerate PRs) and GENERATION.md (the per-binding generator policy: MobilityNebula generates the NES MEOS-operator surface via tools/codegen/codegen_nebula.py from the catalog, family-organized, zero hand special-cases).

What
Brings MobilityNebula onto the ecosystem-wide per-binding generator policy (completing the rollout: JMEOS #29, GoMEOS #6, MEOS.NET #6, meos-rs #4, PyMEOS #96/#21, MobilityDuck #206, MobilitySpark #29, MobilityFlink #32, MobilityKafka #17):
tools/pin/compose-order.txt— the canonical fold manifest of the ~50 open codegen-wave PRs (derived from the live DAG): generator infra feat(codegen): IDL-driven NES MEOS-operator generator with idempotent build/grammar/QPC glue #170 folds first, then the per-family NES operator waves W105–W149 (feat(meos): add GEO_NUM_POINTS/GEOS/SRID/IS_UNITARY, GEO_EQUALS/SAME, GEOG_DISTANCE NES operators (W105) #125–feat(meos): add trgeometry vs trgeometry spatial predicate NES operators (W149) #169), CI fix(ci): make the Nix build work with NES_ENABLE_MEOS=OFF and stock paho-mqtt-cpp #171, and the -22a verify/regenerate PRs verify(codegen): regenerate tfloat/tint-transform operators from -22a IDL #172–feat(meos): add 9 spatial predicate operators via codegen (tgeo/tcbuffer gap-fill) #174.GENERATION.md— the policy: MobilityNebula generates the NES MEOS-operator surface viatools/codegen/codegen_nebula.pyfrom the catalog, family-organized, zero hand special-cases.Docs + manifest only — no code, no build impact.
Why
Per the per-binding generator policy: each binding owns its generator + its own pin manifest, the single source of truth is the MEOS-API catalog, and generation converges to a zero-hand-written surface via generate-then-retire (the last green-CI version is the equivalence probe).
