Kris Nuttycombe 192cb3ffda shardtree: Remove `Node::Pruned` 
In 7e48886fd3, `Node::Pruned` was
introduced in order to fix problems with `LocatedTree::max_position`
resulting from reinsertion of subtree information as children of
a previously pruned subtree represented by a `Node::Leaf` at its
root. This fix introduced a large amount of complexity that is
better resolved by fixing the `max_position` function in a different
way and generally minimizing its usage.

Kris Nuttycombe f5adcd5a2c shardtree: Fix pruning of annotated `Parent` nodes with `Nil` children. 
The current behavior of `unite` incorrectly discards annotation data.

Jack Grigg 020a7d76d7 shardtree: Use `Tree` constructors instead of struct creation 
This makes it easier for us to track where new tree nodes are created,
and how the node kinds are used within the `ShardTree` data model.

Kris Nuttycombe d40e178f8d shardtree: Do not unify pruned nodes with empty nodes. 2024-05-28 19:22:45 -06:00
Kris Nuttycombe 7e48886fd3 shardtree: Add `Pruned` node type 
In circumstances where insertion into a subtree results in pruning, and
then a subsequent insertion within the same range contains leaves that
must be retained, it is necessary to be able to distinguish the maximum
position among notes that have been observed but later pruned. This
fixes a bug wherein an insertion into an already-pruned tree could cause
the maximum position reported for the subtree to regress.

Kris Nuttycombe ffc087424d shardtree: Discard `REFERENCE` retention in leaf overwrites. 
Also, disallow value-conflicted overwrites at the leaf level.

Kris Nuttycombe e55ff2d7f2 incrementalmerkletree: add `Reference` retention type. 
This new retention type is intended to be used when inserting frontiers
that should not automatically be pruned.

Also, improve documentation for the `Retention` type.

Kris Nuttycombe 8d301a14dd shardtree: Add `witness_at_checkpoint_id` methods. 
It is useful to be able to refer to a specific checkpoint, rather than
just a checkpoint depth, when computing a witness.

checkpoint depth, for which one wishes to compute the root.

Jack Grigg 8d699c9667 shardtree: Pass checkpoints alongside tree to `ShardTree::insert_tree` 
There are no `ShardTree` APIs that allow for checkpointing at arbitrary
positions, which makes sense as the relevant leaf may have been pruned.
For this API to be a viable substitute for `ShardTree::batch_insert`, it
therefore needs to support marking any checkpoints associated with the
inserted tree.

Jack Grigg 4666e9e370 shardtree: Don't insert empty subtrees in `ShardTree::insert_tree` 
`ShardTree::max_leaf_position` relies on the invariant that the last
shard in the subtrees vector is never created without a leaf then being
added to it. `LocatedTree::decompose_to_level` can return a trailing
empty subtree for some inputs, and given that it is always correct to
not insert an empty subtree into `self`, we maintain the invariant by
skipping empty subtrees.

Jack Grigg 1eda8b2e24 shardtree: Derive correct shard root addrs in `ShardTree::insert_tree` 
`LocatedTree::decompose_to_level` will return the tree as-is if it is
smaller than a shard, so we can't assume that the address of `subtree`
is a valid shard address.
