+## Introduction
+
+The purpose of a **placement policy** is to determine whichs node(s) of a frostfs system will store an object. Namely, given a **netmap** (a set of nodes) and a placement policy, a subset of those nodes is selected to store a given object. An important aspect is that since nodes in a netmap come and go due to distributed nature of the system, this selection must be deterministic and consistent, i.e. different nodes must come to the same conclusion as long as they share the same view of the netmap.
+
+> ℹ️ Throughout this document, we will consider each node as a dictionary of attributes and a global unique ID.
+
+One way to think about the placement policy, is as a pipeline of operations which begins with a set of nodes (the entire netmap) and gradually refine it into only the nodes that will be in charge of storing the object. More specifically, each operation in this pipeline takes a set of nodes and transforms it into a subset of those nodes. The transformation is done purely on the basis of the node attributes.
+
+![Placement policy as a pipeline](./image/placement_policy.svg)
+
+The three main operations are:
+1. `FILTER`: filters a set of nodes based on their attributes.
+2. `SELECT`: selects a specific amount of nodes from a set of nodes based on certain conditions.
+3. `REP`: specifies how many nodes (and which ones) from a set of nodes are used to store an object.
+
+In the next sections, we will explore each of them in detail.

+Before exploring the operations in detail, we must get acquainted with the basic expressions that appear in a placement policy. As mentioned above, the placement policy operates solely on the basis of node attributes, and as such, basic expressions mostly revolve around node attribute comparison.
+
+A comparison expression expresses whether a node attribute equals a specified value:
+```
+AttributeName Operation AttributeValue
+```
+
+For example, the following expression
+```sql
+City EQ 'Moscow'
+```
+asserts that the node attribute `City` equals the value `Moscow`.
+
+Comparison expressions can be nested via boolean operators and parentheses. For example, the following expression:
+```sql
+(City EQ 'Moscow') AND (Disks GT 2)
+```
+asserts that the node attribute `City` equals the value `Moscow` and the node attribute `Disks` must be greater than `2`. Note that the arguments can be either a string or a number.
+
+See [Appendix 1](#appendix-1-operators) for a complete list of supported operators.
+
+### `FILTER`
+
+A `FILTER` operation takes as input a set of nodes and returns a subset of those nodes. It's useful for selecting nodes that have (or lack) specific attributes. Its basic syntax is as follows:
+```bnf
+FILTER <expr> AS <id>
+```
+
+For example, the following filter
+```sql
+FILTER Color EQ 'Red' AS RedNodes
+```
+selects those nodes for which the `Color` attribute equals `Red`, and discards the rest. The filter's identifier is `RedNodes`, which can be used to reference it in other parts of the placement policy. For example, you could reference the above filter in another filter as follows
+```sql
+FILTER @RedNodes AND (City EQ 'Moscow') AS RedMoscowNodes
+```
+which would select those nodes for which the `Color` attribute equals `Red` and the `City` attribute equals `Moscow`. You can think of the `@` operator as embedding the referenced filter expression verbatim where it's used. This makes it easy to compose filters. However, filters can be referenced via `@` only within filter expressions. In other places you can simply use the filter identifier directly.
+
+> ⚠️ Every filter requires a unique identifier. What would be the use of a filter that you cannot reference?
+
+The following diagram illustrates the filter operation
+
+![FILTER](./image/filter_illustration.svg)
+
+where the nodes are represented as colored circles, with their color representing the value of their `Color` attribute, respectively.
+
+> ℹ️ A filter referring to all nodes in the netmap always exists and can be referenced by `*`.
+
+### `SELECT`
+
+A `SELECT` operation specifies how many and which nodes from a subset previously obtained from a `FILTER` will be available to build replica groups for object storage. It's not that different from a `FILTER` in that it transforms a set of nodes into a subset of those, but while a `FILTER` cannot control the size of the resulting subset and other characteristics, a `SELECT` can.
+
+Its basic syntax is as follows:
+```bnf
+SELECT <count> {IN (SAME|DISTINCT) <attribute>} FROM <filter> {AS <id>}
+```
+
+In a nutshell, a `SELECT` takes a filter result as input and outputs a specific number of nodes, optionally enforcing that all output nodes must either share or differ in a specific attribute. Note that only the output node count and the source filter are required.
+
+Let's see some examples
+```sql
+-- Selects exactly one node from the entire netmap
+SELECT 1 FROM *               
+
+-- Same as above, but with an identifier for the selection
+SELECT 1 FROM * AS ONE        
+
+-- Selects two nodes from the RedOrBlueNodes filter, such that both selected nodes 
+-- share the same value for the Color attribute, i.e. both red or both blue.
+SELECT 2 IN SAME Color FROM RedOrBlueNodes 
+
+-- Selects two nodes from the RedOrBlueNodes filter, such that the selected nodes 
+-- have distinct values for the Color attribute, i.e. one red and one blue.
+-- The selection is also given an identifier.
+SELECT 2 IN DISTINCT Color FROM RedOrBlueNodes AS MyNodes
+```
+
+The last example is illustrated in the following diagram:
+
+![SELECT](./image/select_illustration.svg)
+
+> ℹ️ At this point, notice that while `FILTER`'s output is always unique (namely, every node in the input is either filtered in or out), that is not always the case for `SELECT`. In the last example above, there is more than one way to select two nodes with distinct `Color` attribute. Because we require the output to be deterministic and consistent (so that all nodes agree on which nodes to store a given object without having to commmunicate with each other), we need a way to reach this consensus efficiently. Internally, the policy engine uses [Rendezvouz Hashing](https://en.wikipedia.org/wiki/Rendezvous_hashing) to ensure this. If you want more control over what nodes are actually selected, you can always use narrower filters/selections to ensure this.
+
+### `REP`
+
+A `REP` operation specifies how many copies of an object need to be stored (`REP` stands for "replica"). A placement policy can contain multiple replica operations, with each of them representing a replica group, i.e. a group of objects associated with the same replica. Following our analogy with a pipeline, `REP` operations are the sink or output nodes.
+
+Its basic syntax is as follows:
+```bnf
+REP <count> {IN <select>}
+```
+
+If a select is not specified, then the entire netmap is used as input. The resulting nodes will be used to actually store objects and they constitute a replica group (or simply, "a replica").
+
+Examples
+```sql
+-- A replica consisting of a single copy, stored in an arbitrary node of the netmap.
+REP 1
+
+-- A replica consisting of three copies, each stored in a different node from the selection
+-- identified as 'MyNodes'.
+REP 3 IN MyNodes
+```
+
+The following diagram illustrates the `REP` operation:
+
+![REP](./image/rep_illustration.svg)
+
+> ⚠️ Notice that although we use `REP 1` in the examples, in real life scenarios you almost always want to have more than a single node in each replica for redundancy.
+
+## Policies
+
+In order to specify a complete placement policy, we just need to assemble it from the operations described above.
+
+Its basic (simplified) syntax is as follows:
+```bnf
+<rep>+ <select>* <filter>*
+```
+
+We begin by stating all our `REP` operations, followed by all the `SELECT` operations and finally all the `FILTER` operations. Note that this is the reverse order in which they are applied. Also note that at least one `REP` operation is required.
+
+Here's a complete example:
+```sql
+REP 1 IN MyNodes
+SELECT 2 IN DISTINCT Color FROM RedOrBlueNodes AS MyNodes
+FILTER Color EQ 'Red' AS RedNodes
+FILTER Color EQ 'Blue' AS BlueNodes
+FILTER @RedNodes OR @BlueNodes AS RedOrBlueNodes
+```
+
+In additional to this basic syntax, there are a couple of additional useful options to specify which nodes and how many nodes are actually selected to store objects. We explore these in the next sections.
+
+### The policy playground
+
+> ℹ️ This section assumes you have an up-to-date version of the `frostfs-cli`. 
+
+While simple placement policies have predictable results that can be understood at a glance, more complex ones need careful consideration before deployment. In order to simplify understanding a policy's outcome and experimenting while learning, a builtin tool is provided as part of the `frostfs-cli` for this purpose: the policy playground.
+
+For the remainder of this guide, we will use the policy playground to setup a virtual netmap (that is, one that doesn't require any networking or deployment) and test various policies. In order to visualize this netmap easily, each node will have three attributes: a character, a shape and a color 
+
+![Sample Netmap](./image/sample_netmap.svg)
+
+We can start the policy playground as follows:
+```sh
+$ frostfs-cli container policy-playground
+> 
+```
+
+Since we didn't pass any endpoint, the initial netmap is empty, which we can verify with the `ls` command (to list the nodes in the netmap):
+```sh
+> ls
+>
+```
+
+Nows let's add virtual nodes to represent our test netmap in the figure above
+```sh
+> add 01 Char:A Shape:Circle  Color:Blue
+> add 02 Char:B Shape:Circle  Color:Green
+> add 03 Char:C Shape:Circle  Color:Red
+> add 04 Char:D Shape:Square  Color:Blue
+> add 05 Char:E Shape:Square  Color:Green
+> add 06 Char:F Shape:Square  Color:Red
+> add 07 Char:G Shape:Diamond Color:Blue
+> add 08 Char:H Shape:Diamond Color:Green
+> add 09 Char:I Shape:Diamond Color:Red
+```
+
+and verify that the netmap now contains what we expect
+```sh
+> ls
+	 1: id=06 attrs={Char:F Shape:Square Color:Red}
+	 2: id=08 attrs={Char:H Shape:Diamond Color:Green}
+	 3: id=01 attrs={Char:A Shape:Circle Color:Blue}
+	 4: id=04 attrs={Char:D Shape:Square Color:Blue}
+	 5: id=05 attrs={Char:E Shape:Square Color:Green}
+	 6: id=09 attrs={Char:I Shape:Diamond Color:Red}
+	 7: id=02 attrs={Char:B Shape:Circle Color:Green}
+	 8: id=03 attrs={Char:C Shape:Circle Color:Red}
+	 9: id=07 attrs={Char:G Shape:Diamond Color:Blue}
+```
+
+With our sample netmap setup, we can now continue.
+
+### `CBF`
+
+Consider the following policy:
+
+```sql
+REP 1
+```
+
+It builds a replica consisting of one copy, selected from the entire netmap. If we evaluate this policy in our sample netmap, we obtain a result which is probably unexpected:
+
+```sh
+> eval REP 1
+	 1: [06 05 02]
+```
+
+The `eval` commands evaluates a policy and lists in a separate line the nodes selected for each `REP` operation, in the order they appear in the policy. We were expecting a single node, but we got three instead. The reason is that there's a policy-wide parameter called **container backup factor** (or CBF). This parameter is a multiplier which controls the maximum number of storage nodes: for example, if a policy requires 10 nodes and the CBF is 3, it means that the policy can store an object in up to 10 × 3 nodes. However, if there are not enough nodes and fewer (but at least 10) are used, this is not considered an error.
+
+The default value for CBF is `3`, which explains our result above, given than every node in the netmap agrees with the policy. The CBF can be explicitly set in the policy right after the `REP` operations. For example
+
+```sh
+> eval REP 1 CBF 1
+	 1: [06]
+```
+
+results in what we expected in the first example. On the other hand
+
+```sh
+> eval REP 1 IN MyNodes SELECT 1 IN SAME Char FROM * AS MyNodes
+	 1: [01]
+```
+
+results in a single node despite the default CBF, because there are not enough nodes compatible with the selection.
+
+### `UNIQUE`
+
+Consider the following policy:
+```sql
+REP 1
+REP 1
+CBF 2
+```
+
+If we evaluate it
+```sh
+> eval REP 1 REP 1 CBF 2
+	 1: [06 05]
+	 2: [06 05]
+```
+
+we find that each replica gets two nodes, in accordance with the CBF. However, these nodes are exactly the same and this might not be desirable. In order to force the policy engine to select different nodes for each replica, we can use the `UNIQUE` option, which is specified right before the `REP` operations.
+
+In our example, if we change it to
+```sql
+UNIQUE
+REP 1
+REP 1
+CBF 2
+```
+
+and evaluate it
+
+```sh
+> eval UNIQUE REP 1 REP 1 CBF 2
+	 1: [06 05]
+	 2: [02 03]
+```
+
+we now find that the nodes selected for each replica are now distinct from each other.
+

 WriteObject()

Here is a scenario:
1. `resolveFrostFSErrors` is false.
2. The first object part was not written, which was signified in status.
3. The second part was written correctly.

Client now thinks that the object is written even though it was not.
In theory we could also return only status, but client-side splitting
is not a single RPC, so it makes sense.

Subject: [PATCH 081/323] [#115] pool: Drop part buffer pool

Tests showed that using part buffer pool doesn't save memory a lot.
Especially on big parts.
Probably we can use pool only for small parts
after adding buffer in payloadSizeLimiter

 While simple placement policies have predictable results that can be understood at a glance, more complex ones need careful consideration before deployment.

Subject: [PATCH 099/323] [#169] pool: Close inner pools during close routine

Some apps do not reuse pool instance and expect that
`pool.Close()` free resources. But it didn't actually
close inner SDK clients, so it leads to goroutine leak
in storage.

Subject: [PATCH 103/323] [#171] pool: Use dial status to close connections
 during restarts

Every client restart, pool creates new client instance. If client
failed due to dial error, there was no prior connection and go
routine on a server side. If client failed due to communication
or business logic errors, then server side maintains connection and
client should close it to avoid routine and connection leak.

Dialing is a part of healthcheck, so health status is now a enum
of three values:
- unhealthy due to dial fail,
- unhealthy due to transmission fail,
- healthy.

Subject: [PATCH 116/323] [#167] netmap: Fix reverse min agregator

The higher the price, the lower reverse min weight should be.
Previously nodes with 0 price had 0 weight which is a bit misleading.

Introduced in d71a0e0755f8.

Subject: [PATCH 117/323] [#186] netmap: Marshal policy with brackets

Brackets can be semantically important and must not be omitted,
otherwise the output is plain wrong.
We do not take the responsibility to preserve every bracket, though,
because parser does some optimizations related to grouping long chains
of filters combined with the same operation.

Subject: [PATCH 162/323] [#215] client: Introduce apemanager rpc interface

* Introduce `APEManagerAddChain`, `APEManagerRemoveChain`, `APEManagerListChains`.
* Introduce reqeuest/response types for these handlers (Prm*, Res*).
* Inroduce status type for apemanager `APEManagerAccessDenied`; add unit-tests.

Subject: [PATCH 190/323] [#247] object: Introduce `patcher` package

* Introduce `patcher` package that contains such interfaces to be
  implemented:
  - `PatchApplier` - the main patching engine that merges the stream
    of patches and the stream of original object payload divided by
    ranges. The merged streams result is output to `ChunkedObjectWriter`;
  - `RangeProvider` - provides the original object payload by ranges;
  - `HeaderProvider` - provides the original object header.
* Introduce `patcher` that implements `PatchApplier`;
* Cover all possible cases with unit-tests.

Subject: [PATCH 200/323] [#253] pool: Don't count regular FrostFS errors

Previously we count all frostfs errors like:
ObjectNotFound, EACLNotFound
because frostfs status is unconditionally resolved into built-in go errors
but handleError method handled built-in errors like internal network ones.
Since after resolving frostfs errors status is also returned we start check this first

+# Node connection pool
+
+* Distributes requests between fixed number of nodes
+* Wraps 
+
+The distribution between nodes in connection pool is based on priority and weight parameters from
+NodeParam struct. The distribution model is presented below. On this scheme nodes with the same 
+priority have the same color.
+
+![](./image/pool.png "Pool connections distribution model")
+
+## Priority
+
+Pool component forwards request to the nodes with the highest priority (the lower the value - 
+the higher the priority). The `node 1` from the image's scenario (I) is healthy
+and has the highest priority (1), that's why the pool forwards requests from it. There are no other
+nodes with priority 1, so `node 1` receives all requests. In the second scenario (II) `node 1` 
+becomes unhealthy. In that case pool tries to connect nodes with next in priority nodes e.g. 
+`Node 4` and `node 2`. If all of them become unhealthy too, the pool sends requests to nodes with 
+priority 3 in scenario (III) and so on.
+
+## Weights
+
+If there are several nodes with the same priority, then requests are distributed randomly between
+these nodes based on their weights. To do that the proportion of weights is calculated. 
+For example, for `node 2` and `node 4` with weights 2 and 8 the distribution would be 20 and 80 percent 
+respectively.

  first call.
* Empty payload patches just cut original object payload. So, these

Subject: [PATCH 219/323] [#270] client: Use RPC call instead of Dial

After api-go upgrade created client doesn't establish connection after created,
so RPC call is required to establish and check connection.
RPC call returns status error, so conversion from status error to context error
is required to satisfy Dial contract and unit tests.

Subject: [PATCH 222/323] [#269] Makefile: Update policy target

The previous policy target generated device-specific comments
(e.g., `/home/john_doe/repos/<...>`), which could result in
unnecessary file changes This behavior would confuse git and
require manual changes to resolve. The update ensures comments
are now device-agnostic, preventing unwanted changes.

After removing `grpc.Dial` from client `DialTimeout` used only if
custom dialer provided. Client uses `BalanceOf` instead of `grpc.Dial`,
so it is required to use `DialTimeout` to not to use RPC timeout.

Subject: [PATCH 234/323] [#282] client: Close connection on non-nil error in
 Dial

A particular status code does not imply that a connection has not been
established. However, `Dial()` requires user to call `Close()` only if
the error was nil. Thus, it is `Dial()` responsibility to close
everything if it returns an error.

Introduced after the gRPC update in #270 (6009d089fc69).

Subject: [PATCH 247/323] [#293] object: Fix payload size limiter

* Sending empty chunks by `writeChunk` should not release new
  objects as this doesn't change `payloadSizeLimiter` internal
  state.
* This also fixes the bug with patcher when an offset of a patch
  equals to `MaxSize` - `payloadSizeLimiter` releases object again
  although state is the same. This led to error because EC-encoder
  receieved empty payload and couldn't not process it.

Subject: [PATCH 251/323] [#301] rpc: Make client stream initialization get
 cancelled by dial timeout

* `c.conn` may be already invalidated but the rpc client can't detect this.
  `NewStream` may hang trying to open a stream with invalidated connection.
  Using timer with `dialTimeout` for `NewStream` fixes this problem.

+// Administrator-defined Attributes of the FrostFS Storage Node.
+//
+// `Attribute` is a Key-Value metadata pair. Key name must be a valid UTF-8
+// string. Value can't be empty.
+//
+// Attributes can be constructed into a chain of attributes: any attribute can
+// have a parent attribute and a child attribute (except the first and the
+// last one). A string representation of the chain of attributes in FrostFS
+// Storage Node configuration uses ":" and "/" symbols, e.g.:
+//
+//	`FrostFS_NODE_ATTRIBUTE_1=key1:val1/key2:val2`
+//
+// Therefore the string attribute representation in the Node configuration
+// must use "\:", "\/" and "\\" escaped symbols if any of them appears in an
+// attribute's key or value.
+//
+// Node's attributes are mostly used during Storage Policy evaluation to
+// calculate object's placement and find a set of nodes satisfying policy
+// requirements. There are some "well-known" node attributes common to all the
+// Storage Nodes in the network and used implicitly with default values if not
+// explicitly set:
+//
+//   - Capacity \
+//     Total available disk space in Gigabytes.
+//   - Price \
+//     Price in GAS tokens for storing one GB of data during one Epoch. In node
+//     attributes it's a string presenting floating point number with comma or
+//     point delimiter for decimal part. In the Network Map it will be saved as
+//     64-bit unsigned integer representing number of minimal token fractions.
+//   - UN-LOCODE \
+//     Node's geographic location in
+//     [UN/LOCODE](https://www.unece.org/cefact/codesfortrade/codes_index.html)
+//     format approximated to the nearest point defined in the standard.
+//   - CountryCode \
+//     Country code in
+//     [ISO 3166-1_alpha-2](https://en.wikipedia.org/wiki/ISO_3166-1_alpha-2)
+//     format. Calculated automatically from `UN-LOCODE` attribute.
+//   - Country \
+//     Country short name in English, as defined in
+//     [ISO-3166](https://www.iso.org/obp/ui/#search). Calculated automatically
+//     from `UN-LOCODE` attribute.
+//   - Location \
+//     Place names are given, whenever possible, in their national language
+//     versions as expressed in the Roman alphabet using the 26 characters of
+//     the character set adopted for international trade data interchange,
+//     written without diacritics . Calculated automatically from `UN-LOCODE`
+//     attribute.
+//   - SubDivCode \
+//     Country's administrative subdivision where node is located. Calculated
+//     automatically from `UN-LOCODE` attribute based on `SubDiv` field.
+//     Presented in [ISO 3166-2](https://en.wikipedia.org/wiki/ISO_3166-2)
+//     format.
+//   - SubDiv \
+//     Country's administrative subdivision name, as defined in
+//     [ISO 3166-2](https://en.wikipedia.org/wiki/ISO_3166-2). Calculated
+//     automatically from `UN-LOCODE` attribute.
+//   - Continent \
+//     Node's continent name according to the [Seven-Continent
+//     model](https://en.wikipedia.org/wiki/Continent#Number). Calculated
+//     automatically from `UN-LOCODE` attribute.
+//   - ExternalAddr
+//     Node's preferred way for communications with external clients.
+//     Clients SHOULD use these addresses if possible.
+//     Must contain a comma-separated list of multi-addresses.
+//
+// For detailed description of each well-known attribute please see the

+//
+//     This value refers to the maximum size of a **physically** stored object

+//     }{
+//     \mathrm{Object\ ID\ Size}
+//     }
+//     ```
+//
+//     This arises from the fact that a tombstone, also being an object, stores
+//     the IDs of inhumed objects and cannot be divided into smaller objects,
+//     thus having an upper limit for its size.
+//
+//     For example, if:
+//
+//   - Max Object Size Size = 64 MiB;
+//
+//   - Object ID Size = 32 B;
+//
+//     then:
+//     ```math
+//     \mathrm{Stored\ Object\ Size} \le
+//     \frac{\left(64\ \mathrm{MiB}\right)^2}{32\ \mathrm{B}} =
+//     \frac{2^{52}}{2^5}\ \mathrm{B} =
+//     2^{47}\ \mathrm{B} =
+//     128\ \mathrm{TiB}
+//     ```
+//   - **WithdrawFee** \
+//     Fee paid for withdrawal of funds paid by the account owner.
+//     Value: little-endian integer. Default: 0.
+//   - **MaxECDataCount** \
+//     Maximum number of data shards for EC placement policy.
+//     Value: little-endian integer. Default: 0.

+// Administrator-defined Attributes of the FrostFS Storage Node.
+//
+// `Attribute` is a Key-Value metadata pair. Key name must be a valid UTF-8
+// string. Value can't be empty.
+//
+// Attributes can be constructed into a chain of attributes: any attribute can
+// have a parent attribute and a child attribute (except the first and the
+// last one). A string representation of the chain of attributes in FrostFS
+// Storage Node configuration uses ":" and "/" symbols, e.g.:
+//
+//	`FrostFS_NODE_ATTRIBUTE_1=key1:val1/key2:val2`
+//
+// Therefore the string attribute representation in the Node configuration
+// must use "\:", "\/" and "\\" escaped symbols if any of them appears in an
+// attribute's key or value.
+//
+// Node's attributes are mostly used during Storage Policy evaluation to
+// calculate object's placement and find a set of nodes satisfying policy
+// requirements. There are some "well-known" node attributes common to all the
+// Storage Nodes in the network and used implicitly with default values if not
+// explicitly set:
+//
+//   - Capacity \
+//     Total available disk space in Gigabytes.
+//   - Price \
+//     Price in GAS tokens for storing one GB of data during one Epoch. In node
+//     attributes it's a string presenting floating point number with comma or
+//     point delimiter for decimal part. In the Network Map it will be saved as
+//     64-bit unsigned integer representing number of minimal token fractions.
+//   - UN-LOCODE \
+//     Node's geographic location in
+//     [UN/LOCODE](https://www.unece.org/cefact/codesfortrade/codes_index.html)
+//     format approximated to the nearest point defined in the standard.
+//   - CountryCode \
+//     Country code in
+//     [ISO 3166-1_alpha-2](https://en.wikipedia.org/wiki/ISO_3166-1_alpha-2)
+//     format. Calculated automatically from `UN-LOCODE` attribute.
+//   - Country \
+//     Country short name in English, as defined in
+//     [ISO-3166](https://www.iso.org/obp/ui/#search). Calculated automatically
+//     from `UN-LOCODE` attribute.
+//   - Location \
+//     Place names are given, whenever possible, in their national language
+//     versions as expressed in the Roman alphabet using the 26 characters of
+//     the character set adopted for international trade data interchange,
+//     written without diacritics . Calculated automatically from `UN-LOCODE`
+//     attribute.
+//   - SubDivCode \
+//     Country's administrative subdivision where node is located. Calculated
+//     automatically from `UN-LOCODE` attribute based on `SubDiv` field.
+//     Presented in [ISO 3166-2](https://en.wikipedia.org/wiki/ISO_3166-2)
+//     format.
+//   - SubDiv \
+//     Country's administrative subdivision name, as defined in
+//     [ISO 3166-2](https://en.wikipedia.org/wiki/ISO_3166-2). Calculated
+//     automatically from `UN-LOCODE` attribute.
+//   - Continent \
+//     Node's continent name according to the [Seven-Continent
+//     model](https://en.wikipedia.org/wiki/Continent#Number). Calculated
+//     automatically from `UN-LOCODE` attribute.
+//   - ExternalAddr
+//     Node's preferred way for communications with external clients.
+//     Clients SHOULD use these addresses if possible.
+//     Must contain a comma-separated list of multi-addresses.
+//
+// For detailed description of each well-known attribute please see the
+// corresponding section in FrostFS Technical Specification.

+//     Value: little-endian integer. Default: 0.
+//
+//     This value refers to the maximum size of a **physically** stored object

+//     }{
+//     \mathrm{Object\ ID\ Size}
+//     }
+//     ```
+//
+//     This arises from the fact that a tombstone, also being an object, stores
+//     the IDs of inhumed objects and cannot be divided into smaller objects,
+//     thus having an upper limit for its size.
+//
+//     For example, if:
+//
+//   - Max Object Size Size = 64 MiB;
+//
+//   - Object ID Size = 32 B;
+//
+//     then:
+//     ```math
+//     \mathrm{Stored\ Object\ Size} \le
+//     \frac{\left(64\ \mathrm{MiB}\right)^2}{32\ \mathrm{B}} =
+//     \frac{2^{52}}{2^5}\ \mathrm{B} =
+//     2^{47}\ \mathrm{B} =
+//     128\ \mathrm{TiB}
+//     ```
+//   - **WithdrawFee** \
+//     Fee paid for withdrawal of funds paid by the account owner.
+//     Value: little-endian integer. Default: 0.
+//   - **MaxECDataCount** \
+//     Maximum number of data shards for EC placement policy.
+//     Value: little-endian integer. Default: 0.

+// prefix to the name. Here is the list of fields available via this prefix:
+//
+//   - $Object:version \
+//     version
+//   - $Object:objectID \
+//     object_id
+//   - $Object:containerID \

+//     owner_id
+//   - $Object:creationEpoch \
+//     creation_epoch
+//   - $Object:payloadLength \
+//     payload_length
+//   - $Object:payloadHash \
+//     payload_hash
+//   - $Object:objectType \
+//     object_type
+//   - $Object:homomorphicHash \
+//     homomorphic_hash
+//   - $Object:split.parent \
+//     object_id of parent
+//   - $Object:split.splitID \
+//     16 byte UUIDv4 used to identify the split object hierarchy parts
+//   - $Object:ec.parent \
+//     If the object is stored according to EC policy, then ec_parent
+//     attribute is set to return an id list of all related EC chunks.
+//
+// There are some well-known filter aliases to match objects by certain
+// properties:
+//
+//   - $Object:ROOT \
+//     Returns only `REGULAR` type objects that are not split or that are the
+//     top level root objects in a split hierarchy. This includes objects not
+//     present physically, like large objects split into smaller objects
+//     without a separate top-level root object. Objects of other types like
+//     Locks and Tombstones will not be shown. This filter may be
+//     useful for listing objects like `ls` command of some virtual file
+//     system. This filter is activated if the `key` exists, disregarding the
+//     value and matcher type.
+//   - $Object:PHY \
+//     Returns only objects physically stored in the system. This filter is
+//     activated if the `key` exists, disregarding the value and matcher type.
+//
+// Note: using filters with a key with prefix `$Object:` and match type
+// `NOT_PRESENT `is not recommended since this is not a cross-version
+// approach. Behavior when processing this kind of filters is undefined.

+// prefix to the name. Here is the list of fields available via this prefix:
+//

+//     object_id
+//   - $Object:containerID \

+//     owner_id
+//   - $Object:creationEpoch \
+//     creation_epoch
+//   - $Object:payloadLength \
+//     payload_length
+//   - $Object:payloadHash \
+//     payload_hash
+//   - $Object:objectType \
+//     object_type
+//   - $Object:homomorphicHash \
+//     homomorphic_hash
+//   - $Object:split.parent \
+//     object_id of parent
+//   - $Object:split.splitID \
+//     16 byte UUIDv4 used to identify the split object hierarchy parts
+//   - $Object:ec.parent \
+//     If the object is stored according to EC policy, then ec_parent
+//     attribute is set to return an id list of all related EC chunks.
+//
+// There are some well-known filter aliases to match objects by certain
+// properties:
+//
+//   - $Object:ROOT \
+//     Returns only `REGULAR` type objects that are not split or that are the
+//     top level root objects in a split hierarchy. This includes objects not
+//     present physically, like large objects split into smaller objects
+//     without a separate top-level root object. Objects of other types like
+//     Locks and Tombstones will not be shown. This filter may be
+//     useful for listing objects like `ls` command of some virtual file
+//     system. This filter is activated if the `key` exists, disregarding the
+//     value and matcher type.
+//   - $Object:PHY \
+//     Returns only objects physically stored in the system. This filter is
+//     activated if the `key` exists, disregarding the value and matcher type.
+//
+// Note: using filters with a key with prefix `$Object:` and match type
+// `NOT_PRESENT `is not recommended since this is not a cross-version
+// approach. Behavior when processing this kind of filters is undefined.

+// Declares the general format of the status returns of the FrostFS RPC

+// protocol describes the possible outcomes and details of the operation.
+//
+// Each status is assigned a one-to-one numeric code. Any unique result of an
+// operation in FrostFS is unambiguously associated with the code value.
+//
+// Numerical set of codes is split into 1024-element sections. An enumeration
+// is defined for each section. Values can be referred to in the following ways:
+//
+// * numerical value ranging from 0 to 4,294,967,295 (global code);
+//
+//   - values from enumeration (local code). The formula for the ratio of the
+//     local code (`L`) of a defined section (`S`) to the global one (`G`):
+//     `G = 1024 * S + L`.
+//
+// All outcomes are divided into successful and failed, which corresponds
+// to the success or failure of the operation. The definition of success
+// follows the semantics of RPC and the description of its purpose.
+// The server must not attach code that is the opposite of the outcome type.
+//
+// See the set of return codes in the description for calls.
+//
+// Each status can carry a developer-facing error message. It should be a human

+// should not expect) useful information in the message. Field `details`

+// Declares the general format of the status returns of the FrostFS RPC

+// protocol describes the possible outcomes and details of the operation.
+//
+// Each status is assigned a one-to-one numeric code. Any unique result of an
+// operation in FrostFS is unambiguously associated with the code value.
+//
+// Numerical set of codes is split into 1024-element sections. An enumeration
+// is defined for each section. Values can be referred to in the following ways:
+//
+// * numerical value ranging from 0 to 4,294,967,295 (global code);
+//
+//   - values from enumeration (local code). The formula for the ratio of the
+//     local code (`L`) of a defined section (`S`) to the global one (`G`):
+//     `G = 1024 * S + L`.
+//
+// All outcomes are divided into successful and failed, which corresponds
+// to the success or failure of the operation. The definition of success
+// follows the semantics of RPC and the description of its purpose.
+// The server must not attach code that is the opposite of the outcome type.
+//
+// See the set of return codes in the description for calls.
+//
+// Each status can carry a developer-facing error message. It should be a human
+// readable text in English. The server should not transmit (and the client
+// should not expect) useful information in the message. Field `details`
+// should make the return more detailed.

Subject: [PATCH 269/323] [#326] pool: Fix panic that causes mutex deadlock

Two concurrent 'deleteClientFromMap' calls for
the same client may produce panic and deadlock.

First goroutine acquires lock, removes element
from the map, releases lock.

Second goroutine acquires lock, and throws panic
while trying to call 'close()' on empty struct.
Lock is never released and it causes deadlock for
other goroutines.

Subject: [PATCH 273/323] [#331] pool: Avoid connection leak in tree pool with
 netmap support

To avoid connection leak, call `close()` immediately after connection
is established. In regular tree pool, unhealthy connections are handled
by background goroutine which calls `redialIfNecessary()` to reestablish
connection. Here it is not viable so connection must be close.

Subject: [PATCH 278/323] [#334] rpc: Use DeadlineExceeded error when creating
 stream failed by timeout

According to https://pkg.go.dev/context#pkg-variables, ContextCancelled
should be returned when the context is canceled for some reason other
than its deadline passing. So creating gRPC stream with dial timeout fits
better for context.DeadlineExceeded.

Subject: [PATCH 287/323] [#339] pool/tree: Close replaced connection in client
 map

There is a race condition: multiple clients are created and dialled,
but only one is stored in the map. Others are remaining active but not
used.

With this change, new connection replaces old connection and closes
it.

Subject: [PATCH 291/323] [#342] client: Disable service config query

By default, gRPC fetches TXT report while resolving a domain.
https://github.com/grpc/grpc-go/blob/0914bba6c5c5a545d34bd11e5dee0bbb8eaadd3f/internal/resolver/dns/dns_resolver.go#L336

This leads to a hanging dial if DNS is unavailable, even though the host
may be specified in `/etc/hosts` (hello, localhost!).

Use `grpc.WithDisableServiceConfig()` to override the default.
This option seems impossible to override with `WithGRPCDialOpts()`,
but we do not use service config anyway.

Subject: [PATCH 305/323] [#349] object: Make patcher apply patching for split
 header

* Change `PatchApplier` interface: `ApplyAttributesPatch` -> `ApplyHeaderPatch`.
  Make `ApplyHeaderPatch` receive `ApplyHeaderPatchPrm` as parameter;
* Fix `patcher`: apply patch for split header;
* Fix `patcher` unit-tests. Add test-case for split header;
* Extend `Patch` struct with `NewSplitHeader`;
* Change `ObjectPatcher` interface for client: `PatchAttributes` -> `PatchHeader`.
  Fix `objectPatcher`.
* Fix object transformer: since object header sets `SplitHeader` if it's passed.

Subject: [PATCH 317/323] [#354] api/netmap: Return a slice of parameters
 directly

`IterateParameters` does a poor job:
- it doesn't encapsulate well, because it returns a pointer,
- it has a clunky interface, compared to range loop.

I have decided to return parameter slice and not `iter.Seq` for 2
reasons:
1. There already is `SetParameters`, so `NetworkConfig` struct is
   expected to be modified.
2. This iterator uses pointers, so even with this interface the slice
   can already be changed.

They are used by HRW sorting and it makes sense to store them separately
instead of iterating over all attributes each time we need them.
It also simplifies code: we already parse them in NodeInfo.readFromV2(),
so just save the result.

Subject: [PATCH 320/323] [#35] go.mod: Update go-multiaddr to v0.15.0

New multiaddr release is incompatible with the old one:
https://github.com/multiformats/go-multiaddr/releases/tag/v0.15.0
https://github.com/multiformats/go-multiaddr/blob/master/v015-MIGRATION.md

Thankfully, it seems we are not affected by any breaking changes.

Subject: [PATCH 321/323] [#35] network: Use AppendComponent() for TLS
 encapsulation

As advocated explicitly in https://github.com/multiformats/go-multiaddr/blob/master/v015-MIGRATION.md

Answering a question about safety:
AppendComponent() appends to `a.ma`` in place.
`a.ma` is created by FromString() function,
so there is only a single goroutine appending to it.
Thus, assuming `FromString()` itself is called from a single goroutine,
no data race is introduced.
