      The Ambassador Program (#1308) · 9e403629

      The Ambassador Program on Polkadot Collectives Parachain
      
      The Polkadot Ambassador Program has existed for a while; more
      information can be found
      [here](https://wiki.polkadot.network/docs/ambassadors).
      In this PR, the program is being brought on chain.
      
      ### On Chain Structure
      The on-chain program consists of nine ranks, divided into four
      categories ([full
      list](https://github.com/paritytech/cumulus/blob/c238fb26b75569a11abb57437fd14acd26e05f18/parachains/runtimes/collectives/collectives-polkadot/src/ambassador/mod.rs#L52)):
      - Ambassadors (1-2 tiers)
      - Senior Ambassadors (3-4 tiers)
      - Head Ambassadors (5-7 tiers)
      - Master Ambassadors (8-9 tiers)
      
      Each rank has a corresponding `Origin` (e.g., `HeadAmbassadorsTier5` -
      [full
      list](https://github.com/paritytech/cumulus/blob/c238fb26b75569a11abb57437fd14acd26e05f18/parachains/runtimes/collectives/collectives-polkadot/src/ambassador/origins.rs#L35)),
      which represents the collective voice of members of that rank and above.
      
      ### Referendum
      
      The `AmbassadorReferenda` instance of [referenda
      pallet](https://docs.rs/pallet-referenda/latest/pallet_referenda/)
      consists of [nine
      tracks](https://github.com/paritytech/cumulus/blob/c238fb26b75569a11abb57437fd14acd26e05f18/parachains/runtimes/collectives/collectives-polkadot/src/ambassador/tracks.rs#L51),
      each corresponding to an `Origin`. A referendum taken on `senior
      ambassador tier 4` track invites all members from rank 4 or above to
      vote and commands `SeniorAmbassadors` `Origin`. Every member gets one
      vote plus an additional vote for every excess rank. The referendum
      proposal can be submitted by any member of a senior rank or above.
      
      ### Membership Management
      
      Initial members will be brought on chain via migration, with subsequent
      member management handled through the `AmbassadorCollective` instance of
      [ranked collective
      pallet](https://docs.rs/pallet-ranked-collective/latest/pallet_ranked_collective/).
      Both `Root` and `FellowshipAdmin` `Origins`, commanded via public
      Polkadot referendum, can promote or demote members to and from any rank.
      Members themselves also have the power to promote or demote via its
      referendum, with a senior member vote by the rank two above the new /
      current rank - [full
      configuration](https://github.com/paritytech/cumulus/blob/9ab6aa47063d7e8b67ddc10d9c136037f99c03a3/parachains/runtimes/collectives/collectives-polkadot/src/ambassador/mod.rs#L67).
      
      ### Content Management
      
      The program's on-chain content is managed via the collectives content
      pallet, allowing for setting its charter and making announcements. The
      voice of head ambassadors have the authority to set the charter, while
      announcements can be made by any senior rank member or through a
      referendum among all members.
      
      ### Additional Functionality
      
      The `AmbassadorCore` instance of [core fellowship
      pallet](https://docs.rs/pallet-core-fellowship/latest/pallet_core_fellowship/)
      decorates the ranked collectives pallet with features like salary
      determination, activity/passivity registration, and the handling of
      promotion and demotion periods. While the usage of this pallet is
      optional in the first version, future updates will make it the exclusive
      method for induction/promotion.
      
      Periodic salaries in USDt, payable on Asset Hub, are introduced through
      the [salary
      pallet](https://docs.rs/pallet-salary/latest/pallet_salary/). This
      requires induction into the ambassador core pallet.
      
      Please for more information on the pallets' functionality refer to their
      documentations.
      
      ### Next Steps:
      - Migrate to seed the program members
      - Mint ambassador NFT badges on Asset Hub when promoting
      - Treasury pallet instance for the Ambassador Program

      Replace free for all collation in `cumulus` runtimes (#1251) · a181ced4
      georgepisaltu authored
      
      
      Partially fixes #103 
      
      This PR removes instances of "free for all" collation in the `glutton`,
      `shell`, and `seedling` runtimes and replaces them with Aura instances.
      Aura is configured without a session manager, so the initial authority
      set cannot be changed later on.

      "Common good" vs "System" parachain clean up (#1406) · d569e728
      Branislav Kontur authored
      ## Summary 
      The term "common good parachain" has been abandoned in favor of "system
      parachain" - e.g. [Joe's speech at
      Decoded2023](https://youtu.be/CSO-ERHK2gY?t=456). This pull request
      tries to fix and align code with this vision.
      
      ## Impact
      
      The important change is implementation of `trait IsSystem` for `Id`
      [here](https://github.com/paritytech/polkadot-sdk/pull/1406/files#diff-0b7b4f5b962a18ce980354592b55ab2a27b5a2e9f6f8089ec803ca73853e8583R225-R229)
      where we changed condition from `< 1000` to `<= 1999`, which means that
      all parachain IDs bellow 1999 (included) are considered as "system
      parachain" IDs. This change has a direct impact on the following
      components:
      
      ####
      [ChildSystemParachainAsSuperuser](https://github.com/paritytech/polkadot-sdk/blob/master/polkadot/xcm/xcm-builder/src/origin_conversion.rs#L72-L88)
      This origin converter is used for allowing to process XCM `Transact`
      from "system parachain" on the relay chain - e.g. see [configuration for
      Kusama](https://github.com/paritytech/polkadot-sdk/blob/master/polkadot/runtime/kusama/src/xcm_config.rs#L92-L101).
      Only configured for Kusama, Westend, Rococo runtimes.
      
      **No need for this feature anymore.** See
      [comment](https://github.com/paritytech/polkadot-sdk/pull/1406#issuecomment-1708218715).
      
      ####
      [IsChildSystemParachain](https://github.com/paritytech/polkadot-sdk/blob/master/polkadot/xcm/xcm-builder/src/barriers.rs#L310-L317)
      `IsChildSystemParachain` is used with `AllowExplicitUnpaidExecutionFrom`
      barrier for checking XCM programs (they have to start with
      `UnpaidExecution` instruction).
      Only configured for Kusama, Westend, Rococo runtimes.
      
      **Overall the impact is low or mostly ok because it only allows unpaid
      execution for "system parachains" (e.g. AssetHub, BridgeHub...) on the
      relay chain.**
      
      ####
      [SiblingSystemParachainAsSuperuser](https://github.com/paritytech/polkadot-sdk/blob/master/polkadot/xcm/xcm-builder/src/origin_conversion.rs#L94-L114)
      
      Not used anywhere in `polkadot-sdk` repo.
      
      
      ## Unresolved Questions
      - [ ] constants `LOWEST_USER_ID` and `LOWEST_PUBLIC_ID` seem to express
      the same thing now, do we want to keep them both or deprecated one of
      them? If so, which one?
      - [x] determine impact for `ChildSystemParachainAsSuperuser`
      
      ## TODO
      
      - [ ] when merged here, open PR to the `polkadot-fellows`

      * move min backing votes const to runtime

      Signed-off-by: default avataralindima <[email protected]>
      
      * add runtime migration
      
      * introduce api versioning for min_backing votes
      
      also enable it for rococo/versi for testing
      
      * also add min_backing_votes runtime calls to statement-distribution
      
      this dependency has been recently introduced by async backing
      
      * remove explicit version runtime API call
      
      this is not needed, as the RuntimeAPISubsystem already takes care
      of versioning and will return NotSupported if the version is not
      right.
      
      * address review comments
      
      - parametrise backing votes runtime API with session index
      - remove RuntimeInfo usage in backing subsystem, as runtime API
      caches the min backing votes by session index anyway.
      - move the logic for adjusting the configured needed backing votes with the size of the backing group
      to a primitives helper.
      - move the legacy min backing votes value to a primitives helper.
      - mark JoinMultiple error as fatal, since the Canceled (non-multiple) counterpart is also fatal.
      - make backing subsystem handle fatal errors for new leaves update.
      - add HostConfiguration consistency check for zeroed backing votes threshold
      - add cumulus accompanying change
      
      * fix cumulus test compilation
