+# Service type-LoadBalancer Network Load Balancer with Security Group
+
+## Overview
+
+The controller can be configured to enable managed Security Group (SG) for Services using AWS Network Load Balancer (NLB) by setting an opt-in configuration in your cloud config. When enabled, each NLB created for a Kubernetes Service of type `LoadBalancer` with annotation `service.beta.kubernetes.io/aws-load-balancer-type=nlb` will have a dedicated Security Group, managed by the cloud provider controller. We are calling this as opt-in Managed NLB Security Group ("Managed SG" mode).
+
+> Note: The BYO SG (user-provided security groups) annotations (`service.beta.kubernetes.io/aws-load-balancer-security-groups` and `service.beta.kubernetes.io/aws-load-balancer-extra-security-groups`) are valid only for Classic Load Balancers. To learn more about supported annotations by load balancer type, see the [service_controller documentation][doc-ctrl-service].
+
+[doc-ctrl-service]: https://github.com/kubernetes/cloud-provider-aws/blob/master/docs/service_controller.md
+
+## Configuration
+
+### Opt-in Managed Security Group mode
+
+To enable this feature, add the following to your cloud config (usually `/etc/kubernetes/cloud-config` or as configured in your deployment):
+
+```ini
+[Global]
+NLBSecurityGroupMode = Managed
+```
+
+- **Default behavior:** If `NLBSecurityGroupMode` is not set or set to any value other than `Managed`, NLBs are provisioned without a dedicated, controller-managed Security Group (legacy behavior).
+- **Opt-in behavior:** When set to `Managed`, the controller will create, attach, update, and delete a dedicated SG for each NLB Service.
+
+## Feature Details and Use Cases
+
+- **Why use this feature?**
+ - Improved security: fine-grained, automated control over NLB ingress.
+ - Automated lifecycle management of SGs, reducing manual intervention and risk of resource leaks.
+- **When to use:**
+ - When you want the controller to manage NLB security groups automatically for NLB.
+ - When your security/compliance policies require explicit SGs for each NLB.
+
+## Upgrade and Migration Notes
+
+- **Enabling the feature:**
+ - Existing Service type-loadBalancer NLB will not be retroactively assigned a managed SG. Only new Services (created after enabling the feature) will have managed SGs.
+ - To migrate existing NLBs, you must recreate the Service or manually update the SGs.
+- **Disabling the feature:**
+ - If you disable the feature after using it, previously managed SGs will not be deleted automatically unless the Service and associated NLB is deleted.
+- **Controller restart:**
+ - Changing the config requires a controller restart for the new setting to take effect.
+
+## Security Group Lifecycle
+
+### Managed Security Group
+
+- **Creation:**
+ - SGs are created with owned cluster tag indicating they are managed by the controller.
+- **Tagging:**
+ - Managed SGs are tagged for identification and safe cleanup. Example cluster tag:
+ - `kubernetes.io/cluster/: owned`
+- **Deletion:**
+ - Managed SGs are deleted when the corresponding Service is deleted. The controller uses exponential backoff to handle AWS dependency violations.
+
+## Testing and Validation
+
+### Test 1 - **How to test the Managed Security Group:**
+
+ 1. Ensure your cloud-config has the configuration `NLBSecurityGroupMode = Managed`
+ 2. Create a Service of type `LoadBalancer` after enabling the feature.
+```sh
+APP_NAME=app
+APP_NAMESPACE=$APP_NAME
+SVC_NAME="${APP_NAME}-nlb-sg"
+cat << EOF | kubectl create -f -
+apiVersion: v1
+kind: Service
+metadata:
+ name: "${SVC_NAME}"
+ namespace: "${APP_NAMESPACE}"
+ annotations:
+ service.beta.kubernetes.io/aws-load-balancer-type: nlb
+spec:
+ selector:
+ app: "${APP_NAME}"
+ ports:
+ - port: 80
+ targetPort: 8080
+ protocol: TCP
+ type: LoadBalancer
+EOF
+```
+ 3. Verify that a managed SG is created and attached to the NLB in the AWS console.
+ 4. Check that the SG is tagged appropriately and that ingress rules match your Service spec.
+ 5. Ensure you can reach the Service NLB endpoint:
+```sh
+LB_DNS=$(kubectl get svc $SVC_NAME -n ${APP_NAMESPACE} -o jsonpath='{.status.loadBalancer.ingress[0].hostname}')
+
+aws elbv2 describe-tags --resource-arns $(aws elbv2 describe-load-balancers | jq -r ".LoadBalancers[] | select(.DNSName==\"$LB_DNS\").LoadBalancerArn") | jq .TagDescriptions[].Tags
+
+[
+ {
+ "Key": "kubernetes.io/service-name",
+ "Value": "app/app-svc-ccm"
+ },
+ {
+ "Key": "kubernetes.io/cluster/mrb-sg-zvcgr",
+ "Value": "owned"
+ }
+]
+
+# reach the LB endpoint
+curl -v $LB_DNS
+```
+ 4. Delete the Service and verify that the SG is deleted.
+
+## Troubleshooting
+
+- **SG not deleted:**
+ - Check for AWS dependency violations (e.g., NLB still deleting). The controller will retry deletion with backoff.
+- **NLB not created:**
+ - Ensure the controller has IAM permissions to manage Security Groups.
+- **SG rules not as expected:**
+ - Check your Service annotations and cloud config.
+- **Config changes not taking effect:**
+ - Ensure you have restarted the controller after changing the config.

+## Target group attributes for Service type-loadBalancer NLB
+
+The following target group attributes are supported by the controller using the annotation `service.beta.kubernetes.io/aws-load-balancer-target-group-attributes`:
+
+| Attribute | Values | Description |
+| -- | -- | -- |
+| preserve_client_ip.enabled | [true\|false] | Whether to preserve client IP addresses when terminating connections at the target group level |
+| proxy_protocol_v2.enabled | [true\|false] | Whether to enable proxy protocol v2 on the target group |
+
+**Format:** Attributes are specified as `key=value` pairs, separated by commas.
+
+**Example:**
+```yaml
+service.beta.kubernetes.io/aws-load-balancer-target-group-attributes: preserve_client_ip.enabled=true,proxy_protocol_v2.enabled=false
+```
+
+### Usage Example 1 - working with hairpin connection on internal NLB
+
+The following Service example changes the Target Group Traffic Control attribute "Preserve client IP addresses" from the default (`true`, when target type is instance) to `false`:
+
+```yaml
+apiVersion: v1
+kind: Service
+metadata:
+ name: $SVC_NAME
+ namespace: ${APP_NAMESPACE}
+ annotations:
+ service.beta.kubernetes.io/aws-load-balancer-type: nlb
+ service.beta.kubernetes.io/aws-load-balancer-internal: true
+ service.beta.kubernetes.io/aws-load-balancer-target-group-attributes: preserve_client_ip.enabled=false
+[...]
+```
+
+### Usage Example 2 - working with hairpin connection on internal NLB tracking source IP address
+
+The following example allow users to fine tune the Services for a backend which requires tracking the original source IP address of internal Load Balancers NLB with support of hairpin connections:
+
+
+```yaml
+apiVersion: v1
+kind: Service
+metadata:
+ name: $SVC_NAME
+ namespace: ${APP_NAMESPACE}

+(CEL) project, we pledge to respect everyone who contributes by
+posting issues, updating documentation, submitting pull requests,
+providing feedback in comments, and any other activities.
+
+Communication through any of CEL's channels (GitHub, Gitter, IRC,

+insults, or other unprofessional conduct.
+
+We promise to extend courtesy and respect to everyone involved in this

+disability, age, race, ethnicity, religion, or level of experience. We
+expect anyone contributing to the project to do the same.
+
+If any member of the community violates this code of conduct, the

+# How to Contribute
+
+We'd love to accept your patches and contributions to this project. There are a
+few guidelines you need to follow.
+
+## Contributor License Agreement
+
+Contributions to this project must be accompanied by a Contributor License
+Agreement. You (or your employer) retain the copyright to your contribution,
+this simply gives us permission to use and redistribute your contributions as
+part of the project. Head over to to see
+your current agreements on file or to sign a new one.
+
+You generally only need to submit a CLA once, so if you've already submitted one
+(even if it was for a different project), you probably don't need to do it
+again.
+
+## Code reviews
+
+All submissions, including submissions by project members, require review. We
+use GitHub pull requests for this purpose. Consult
+[GitHub Help](https://help.github.com/articles/about-pull-requests/) for more
+information on using pull requests.
+
+## What to expect from maintainers
+
+Expect maintainers to respond to new issues or pull requests within a week.
+For outstanding and ongoing issues and particularly for long-running
+pull requests, expect the maintainers to review within a week of a
+contributor asking for a new review. There is no commitment to resolution --
+merging or closing a pull request, or fixing or closing an issue -- because some
+issues will require more discussion than others.

+# Project Governance
+
+This document defines the governance process for the CEL language. CEL is
+Google-developed, but openly governed. Major contributors to the CEL
+specification and its corresponding implementations constitute the CEL
+Language Council. New members may be added by a unanimous vote of the
+Council.
+
+The MAINTAINERS.md file lists the members of the CEL Language Council, and
+unofficially indicates the "areas of expertise" of each member with respect
+to the publicly available CEL repos.
+
+## Code Changes
+
+Code changes must follow the standard pull request (PR) model documented in the
+CONTRIBUTING.md for each CEL repo. All fixes and features must be reviewed by a
+maintainer. The maintainer reserves the right to request that any feature
+request (FR) or PR be reviewed by the language council.
+
+## Syntax and Semantic Changes
+
+Syntactic and semantic changes must be reviewed by the CEL Language Council.
+Maintainers may also request language council review at their discretion.
+
+The review process is as follows:
+
+- Create a Feature Request in the CEL-Spec repo. The feature description will
+ serve as an abstract for the detailed design document.
+- Co-develop a design document with the Language Council.
+- Once the proposer gives the design document approval, the document will be
+ linked to the FR in the CEL-Spec repo and opened for comments to members of
+ the cel-lang-discuss@googlegroups.com.
+- The Language Council will review the design doc at the next council meeting
+ (once every three weeks) and the council decision included in the document.
+
+If the proposal is approved, the spec will be updated by a maintainer (if
+applicable) and a rationale will be included in the CEL-Spec wiki to ensure
+future developers may follow CEL's growth and direction over time.
+
+Approved proposals may be implemented by the proposer or by the maintainers as
+the parties see fit. At the discretion of the maintainer, changes from the
+approved design are permitted during implementation if they improve the user
+experience and clarity of the feature.

+# Common Expression Language
+
+The Common Expression Language (CEL) implements common semantics for expression
+evaluation, enabling different applications to more easily interoperate.
+
+Key Applications
+
+* Security policy: organizations have complex infrastructure and need common
+ tooling to reason about the system as a whole
+* Protocols: expressions are a useful data type and require interoperability
+ across programming languages and platforms.
+
+
+Guiding philosophy:
+
+1. Keep it small & fast.
+ * CEL evaluates in linear time, is mutation free, and not Turing-complete.
+ This limitation is a feature of the language design, which allows the
+ implementation to evaluate orders of magnitude faster than equivalently
+ sandboxed JavaScript.
+2. Make it extensible.
+ * CEL is designed to be embedded in applications, and allows for
+ extensibility via its context which allows for functions and data to be
+ provided by the software that embeds it.
+3. Developer-friendly.
+ * The language is approachable to developers. The initial spec was based
+ on the experience of developing Firebase Rules and usability testing
+ many prior iterations.
+ * The library itself and accompanying toolings should be easy to adopt by
+ teams that seek to integrate CEL into their platforms.
+
+The required components of a system that supports CEL are:
+
+* The textual representation of an expression as written by a developer. It is
+ of similar syntax to expressions in C/C++/Java/JavaScript
+* A representation of the program's abstract syntax tree (AST).
+* A compiler library that converts the textual representation to the binary
+ representation. This can be done ahead of time (in the control plane) or
+ just before evaluation (in the data plane).
+* A context containing one or more typed variables, often protobuf messages.
+ Most use-cases will use `attribute_context.proto`
+* An evaluator library that takes the binary format in the context and
+ produces a result, usually a Boolean.
+
+For use cases which require persistence or cross-process communcation, it is
+highly recommended to serialize the type-checked expression as a protocol
+buffer. The CEL team will maintains canonical protocol buffers for ASTs and
+will keep these versions identical and wire-compatible in perpetuity:
+
+* [CEL canonical](https://github.com/google/cel-spec/tree/master/proto/cel/expr)
+* [CEL v1alpha1](https://github.com/googleapis/googleapis/tree/master/google/api/expr/v1alpha1)
+
+
+Example of boolean conditions and object construction:
+
+``` c
+// Condition
+account.balance >= transaction.withdrawal
+ || (account.overdraftProtection
+ && account.overdraftLimit >= transaction.withdrawal - account.balance)
+
+// Object construction
+common.GeoPoint{ latitude: 10.0, longitude: -5.5 }
+```
+

+
+IMPORTANT: Please submit PRs via a clone of the https://github.com/antlr/antlr4 repo, and not here.
+
+ - Do not submit PRs or any change requests to this repo
+ - This repo is read only and is updated by the ANTLR team to create a new release of the Go Runtime for ANTLR
+ - This repo contains the Go runtime that your generated projects should import
+
+## Introduction
+
+This repo contains the official modules for the Go Runtime for ANTLR. It is a copy of the runtime maintained
+at: https://github.com/antlr/antlr4/tree/master/runtime/Go/antlr and is automatically updated by the ANTLR team to create
+the official Go runtime release only. No development work is carried out in this repo and PRs are not accepted here.
+
+The dev branch of this repo is kept in sync with the dev branch of the main ANTLR repo and is updated periodically.
+
+### Why?
+
+The `go get` command is unable to retrieve the Go runtime when it is embedded so
+deeply in the main repo. A `go get` against the `antlr/antlr4` repo, while retrieving the correct source code for the runtime,
+does not correctly resolve tags and will create a reference in your `go.mod` file that is unclear, will not upgrade smoothly and
+causes confusion.
+
+For instance, the current Go runtime release, which is tagged with v4.13.0 in `antlr/antlr4` is retrieved by go get as:
+
+```sh
+require (
+ github.com/antlr/antlr4/runtime/Go/antlr/v4 v4.0.0-20230219212500-1f9a474cc2dc
+)
+```
+
+Where you would expect to see:
+
+```sh
+require (
+ github.com/antlr/antlr4/runtime/Go/antlr/v4 v4.13.0
+)
+```
+
+The decision was taken to create a separate org in a separate repo to hold the official Go runtime for ANTLR and
+from whence users can expect `go get` to behave as expected.
+
+
+# Documentation
+Please read the official documentation at: https://github.com/antlr/antlr4/blob/master/doc/index.md for tips on
+migrating existing projects to use the new module location and for information on how to use the Go runtime in
+general.

+Package antlr implements the Go version of the ANTLR 4 runtime.
+
+# The ANTLR Tool
+
+ANTLR (ANother Tool for Language Recognition) is a powerful parser generator for reading, processing, executing,
+or translating structured text or binary files. It's widely used to build languages, tools, and frameworks.
+From a grammar, ANTLR generates a parser that can build parse trees and also generates a listener interface
+(or visitor) that makes it easy to respond to the recognition of phrases of interest.
+
+# Go Runtime
+
+At version 4.11.x and prior, the Go runtime was not properly versioned for go modules. After this point, the runtime
+source code to be imported was held in the `runtime/Go/antlr/v4` directory, and the go.mod file was updated to reflect the version of
+ANTLR4 that it is compatible with (I.E. uses the /v4 path).
+
+However, this was found to be problematic, as it meant that with the runtime embedded so far underneath the root
+of the repo, the `go get` and related commands could not properly resolve the location of the go runtime source code.
+This meant that the reference to the runtime in your `go.mod` file would refer to the correct source code, but would not
+list the release tag such as @4.12.0 - this was confusing, to say the least.
+
+As of 4.12.1, the runtime is now available as a go module in its own repo, and can be imported as `github.com/antlr4-go/antlr`
+(the go get command should also be used with this path). See the main documentation for the ANTLR4 project for more information,
+which is available at [ANTLR docs]. The documentation for using the Go runtime is available at [Go runtime docs].
+
+This means that if you are using the source code without modules, you should also use the source code in the [new repo].
+Though we highly recommend that you use go modules, as they are now idiomatic for Go.
+
+I am aware that this change will prove Hyrum's Law, but am prepared to live with it for the common good.
+
+Go runtime author: [Jim Idle] jimi@idle.ws
+
+# Code Generation
+
+ANTLR supports the generation of code in a number of [target languages], and the generated code is supported by a
+runtime library, written specifically to support the generated code in the target language. This library is the
+runtime for the Go target.
+
+To generate code for the go target, it is generally recommended to place the source grammar files in a package of
+their own, and use the `.sh` script method of generating code, using the go generate directive. In that same directory
+it is usual, though not required, to place the antlr tool that should be used to generate the code. That does mean
+that the antlr tool JAR file will be checked in to your source code control though, so you are, of course, free to use any other
+way of specifying the version of the ANTLR tool to use, such as aliasing in `.zshrc` or equivalent, or a profile in
+your IDE, or configuration in your CI system. Checking in the jar does mean that it is easy to reproduce the build as
+it was at any point in its history.
+
+Here is a general/recommended template for an ANTLR based recognizer in Go:

+Make sure that the package statement in your grammar file(s) reflects the go package the generated code will exist in.
+
+The generate.go file then looks like this:
+
+ package parser
+
+ //go:generate ./generate.sh
+
+And the generate.sh file will look similar to this:
+
+ #!/bin/sh
+
+ alias antlr4='java -Xmx500M -cp "./antlr4-4.12.1-complete.jar:$CLASSPATH" org.antlr.v4.Tool'
+ antlr4 -Dlanguage=Go -no-visitor -package parsing *.g4
+
+depending on whether you want visitors or listeners or any other ANTLR options. Not that another option here
+is to generate the code into a
+
+From the command line at the root of your source package (location of go.mo)d) you can then simply issue the command:
+
+ go generate ./...
+
+Which will generate the code for the parser, and place it in the parsing package. You can then use the generated code
+by importing the parsing package.
+
+There are no hard and fast rules on this. It is just a recommendation. You can generate the code in any way and to anywhere you like.

+// rule and uses the default error recovery, which consumes until the
+// reSynchronization set of the current rule.
+//
+// If the sub-rule is optional
+//
+// ({@code (...)?}, {@code (...)*},
+//
+// or a block with an empty alternative), then the expected set includes what follows
+// the sub-rule.
+//
+// During loop iteration, it consumes until it sees a token that can start a
+// sub-rule or what follows loop. Yes, that is pretty aggressive. We opt to
+// stay in the loop as long as possible.
+//
+// # Origins
+//
+// Previous versions of ANTLR did a poor job of their recovery within loops.
+// A single mismatch token or missing token would force the parser to bail
+// out of the entire rules surrounding the loop. So, for rule:
+//
+// classfunc : 'class' ID '{' member* '}'
+//
+// input with an extra token between members would force the parser to
+// consume until it found the next class definition rather than the next
+// member definition of the current class.
+//
+// This functionality cost a bit of effort because the parser has to
+// compare the token set at the start of the loop and at each iteration. If for
+// some reason speed is suffering for you, you can turn off this
+// functionality by simply overriding this method as empty:

+//
+// This local follow set only includes tokens
+// from within the rule i.e., the FIRST computation done by
+// ANTLR stops at the end of a rule.
+//
+// # Example
+//
+// When you find a "no viable alt exception", the input is not
+// consistent with any of the alternatives for rule r. The best
+// thing to do is to consume tokens until you see something that
+// can legally follow a call to r or any rule that called r.
+// You don't want the exact set of viable next tokens because the
+// input might just be missing a token--you might consume the
+// rest of the input looking for one of the missing tokens.
+//
+// Consider the grammar:
+//
+// a : '[' b ']'
+// | '(' b ')'
+// ;
+//
+// b : c '^' INT
+// ;
+//
+// c : ID
+// | INT
+// ;
+//
+// At each rule invocation, the set of tokens that could follow
+// that rule is pushed on a stack. Here are the various
+// context-sensitive follow sets:
+//
+// FOLLOW(b1_in_a) = FIRST(']') = ']'
+// FOLLOW(b2_in_a) = FIRST(')') = ')'
+// FOLLOW(c_in_b) = FIRST('^') = '^'
+//
+// Upon erroneous input “[]”, the call chain is
+//
+// a → b → c
+//
+// and, hence, the follow context stack is:
+//
+// Depth Follow set Start of rule execution
+// 0 a (from main())
+// 1 ']' b
+// 2 '^' c
+//
+// Notice that ')' is not included, because b would have to have
+// been called from a different context in rule a for ')' to be
+// included.
+//
+// For error recovery, we cannot consider FOLLOW(c)
+// (context-sensitive or otherwise). We need the combined set of
+// all context-sensitive FOLLOW sets - the set of all tokens that
+// could follow any reference in the call chain. We need to
+// reSync to one of those tokens. Note that FOLLOW(c)='^' and if
+// we reSync'd to that token, we'd consume until EOF. We need to
+// Sync to context-sensitive FOLLOWs for a, b, and c:
+//
+// {']','^'}
+//
+// In this case, for input "[]", LA(1) is ']' and in the set, so we would
+// not consume anything. After printing an error, rule c would
+// return normally. Rule b would not find the required '^' though.
+// At this point, it gets a mismatched token error and panics an
+// exception (since LA(1) is not in the viable following token
+// set). The rule exception handler tries to recover, but finds
+// the same recovery set and doesn't consume anything. Rule b
+// exits normally returning to rule a. Now it finds the ']' (and
+// with the successful Match exits errorRecovery mode).
+//
+// So, you can see that the parser walks up the call chain looking
+// for the token that was a member of the recovery set.
+//
+// Errors are not generated in errorRecovery mode.
+//
+// ANTLR's error recovery mechanism is based upon original ideas:
+//
+// [Algorithms + Data Structures = Programs] by Niklaus Wirth and
+// [A note on error recovery in recursive descent parsers].
+//
+// Later, Josef Grosch had some good ideas in [Efficient and Comfortable Error Recovery in Recursive Descent
+// Parsers]
+//
+// Like Grosch I implement context-sensitive FOLLOW sets that are combined at run-time upon error to avoid overhead
+// during parsing. Later, the runtime Sync was improved for loops/sub-rules see [Sync] docs

+// prediction should only fall back to LL when the additional lookahead
+// cannot lead to a unique SLL prediction.
+//
+// Assuming combined SLL+LL parsing, an SLL configuration set with only
+// conflicting subsets should fall back to full LL, even if the
+// configuration sets don't resolve to the same alternative, e.g.
+//
+// {1,2} and {3,4}
+//
+// If there is at least one non-conflicting
+// configuration, SLL could continue with the hopes that more lookahead will
+// resolve via one of those non-conflicting configurations.
+//
+// Here's the prediction termination rule them: SLL (for SLL+LL parsing)
+// stops when it sees only conflicting configuration subsets. In contrast,
+// full LL keeps going when there is uncertainty.
+//
+// # Heuristic
+//
+// As a heuristic, we stop prediction when we see any conflicting subset
+// unless we see a state that only has one alternative associated with it.
+// The single-alt-state thing lets prediction continue upon rules like
+// (otherwise, it would admit defeat too soon):
+//
+// [12|1|[], 6|2|[], 12|2|[]]. s : (ID | ID ID?) ;
+//
+// When the [ATN] simulation reaches the state before ';', it has a
+// [DFA] state that looks like:
+//
+// [12|1|[], 6|2|[], 12|2|[]]
+//
+// Naturally
+//
+// 12|1|[] and 12|2|[]
+//
+// conflict, but we cannot stop processing this node because alternative to has another way to continue,
+// via
+//
+// [6|2|[]]
+//
+// It also let's us continue for this rule:
+//
+// [1|1|[], 1|2|[], 8|3|[]] a : A | A | A B ;
+//
+// After Matching input A, we reach the stop state for rule A, state 1.
+// State 8 is the state immediately before B. Clearly alternatives 1 and 2
+// conflict and no amount of further lookahead will separate the two.
+// However, alternative 3 will be able to continue, and so we do not stop
+// working on this state. In the previous example, we're concerned with
+// states associated with the conflicting alternatives. Here alt 3 is not
+// associated with the conflicting configs, but since we can continue
+// looking for input reasonably, don't declare the state done.
+//
+// # Pure SLL Parsing
+//
+// To handle pure SLL parsing, all we have to do is make sure that we
+// combine stack contexts for configurations that differ only by semantic
+// predicate. From there, we can do the usual SLL termination heuristic.
+//
+// # Predicates in SLL+LL Parsing
+//
+// SLL decisions don't evaluate predicates until after they reach [DFA] stop
+// states because they need to create the [DFA] cache that works in all
+// semantic situations. In contrast, full LL evaluates predicates collected
+// during start state computation, so it can ignore predicates thereafter.
+// This means that SLL termination detection can totally ignore semantic
+// predicates.
+//
+// Implementation-wise, [ATNConfigSet] combines stack contexts but not

+// means we can stop since no more lookahead will change that fact. On the
+// other hand, there might be multiple conflicts that resolve to different
+// minimums. That means we need more look ahead to decide which of those
+// alternatives we should predict.
+//
+// The basic idea is to split the set of configurations 'C', into
+// conflicting subsets (s, _, ctx, _) and singleton subsets with
+// non-conflicting configurations. Two configurations conflict if they have
+// identical [ATNConfig].state and [ATNConfig].context values
+// but a different [ATNConfig].alt value, e.g.
+//
+// (s, i, ctx, _)
+//
+// and
+//
+// (s, j, ctx, _) ; for i != j
+//
+// Reduce these configuration subsets to the set of possible alternatives.
+// You can compute the alternative subsets in one pass as follows:
+//
+// A_s,ctx = {i | (s, i, ctx, _)}
+//
+// for each configuration in C holding s and ctx fixed.
+//
+// Or in pseudo-code:
+//
+// for each configuration c in C:
+// map[c] U = c.ATNConfig.alt alt // map hash/equals uses s and x, not alt and not pred
+//
+// The values in map are the set of
+//
+// A_s,ctx
+//
+// sets.
+//
+// If
+//
+// |A_s,ctx| = 1
+//
+// then there is no conflict associated with s and ctx.
+//
+// Reduce the subsets to singletons by choosing a minimum of each subset. If
+// the union of these alternative subsets is a singleton, then no amount of
+// further lookahead will help us. We will always pick that alternative. If,
+// however, there is more than one alternative, then we are uncertain which
+// alternative to predict and must continue looking for resolution. We may
+// or may not discover an ambiguity in the future, even if there are no
+// conflicting subsets this round.
+//
+// The biggest sin is to terminate early because it means we've made a
+// decision but were uncertain as to the eventual outcome. We haven't used
+// enough lookahead. On the other hand, announcing a conflict too late is no
+// big deal; you will still have the conflict. It's just inefficient. It
+// might even look until the end of file.
+//
+// No special consideration for semantic predicates is required because
+// predicates are evaluated on-the-fly for full LL prediction, ensuring that
+// no configuration contains a semantic context during the termination
+// check.
+//
+// # Conflicting Configs
+//
+// Two configurations:
+//
+// (s, i, x) and (s, j, x')
+//
+// conflict when i != j but x = x'. Because we merge all
+// (s, i, _) configurations together, that means that there are at
+// most n configurations associated with state s for
+// n possible alternatives in the decision. The merged stacks
+// complicate the comparison of configuration contexts x and x'.
+//
+// Sam checks to see if one is a subset of the other by calling
+// merge and checking to see if the merged result is either x or x'.
+// If the x associated with lowest alternative i
+// is the superset, then i is the only possible prediction since the
+// others resolve to min(i) as well. However, if x is
+// associated with j > i then at least one stack configuration for
+// j is not in conflict with alternative i. The algorithm
+// should keep going, looking for more lookahead due to the uncertainty.
+//
+// For simplicity, I'm doing an equality check between x and
+// x', which lets the algorithm continue to consume lookahead longer
+// than necessary. The reason I like the equality is of course the
+// simplicity but also because that is the test you need to detect the
+// alternatives that are actually in conflict.
+//
+// # Continue/Stop Rule
+//
+// Continue if the union of resolved alternative sets from non-conflicting and
+// conflicting alternative subsets has more than one alternative. We are
+// uncertain about which alternative to predict.
+//
+// The complete set of alternatives,
+//
+// [i for (_, i, _)]
+//
+// tells us which alternatives are still in the running for the amount of input we've
+// consumed at this point. The conflicting sets let us to strip away
+// configurations that won't lead to more states because we resolve
+// conflicts to the configuration with a minimum alternate for the
+// conflicting set.
+//
+// Cases
+//
+// - no conflicts and more than 1 alternative in set => continue
+// - (s, 1, x), (s, 2, x), (s, 3, z), (s', 1, y), (s', 2, y) yields non-conflicting set

+// Useful for rewriting out a buffered input token stream after doing some
+// augmentation or other manipulations on it.
+
+//
+// You can insert stuff, replace, and delete chunks. Note that the operations
+// are done lazily--only if you convert the buffer to a {@link String} with
+// {@link TokenStream#getText()}. This is very efficient because you are not
+// moving data around all the time. As the buffer of tokens is converted to
+// strings, the {@link #getText()} method(s) scan the input token stream and
+// check to see if there is an operation at the current index. If so, the
+// operation is done and then normal {@link String} rendering continues on the
+// buffer. This is like having multiple Turing machine instruction streams
+// (programs) operating on a single input tape. :)
+//
+
+// This rewriter makes no modifications to the token stream. It does not ask the
+// stream to fill itself up nor does it advance the input cursor. The token
+// stream {@link TokenStream#index()} will return the same value before and
+// after any {@link #getText()} call.
+
+//
+// The rewriter only works on tokens that you have in the buffer and ignores the
+// current input cursor. If you are buffering tokens on-demand, calling
+// {@link #getText()} halfway through the input will only do rewrites for those
+// tokens in the first half of the file.
+
+//
+// Since the operations are done lazily at {@link #getText}-time, operations do
+// not screw up the token index values. That is, an insert operation at token
+// index {@code i} does not change the index values for tokens
+// {@code i}+1..n-1.
+
+//
+// Because operations never actually alter the buffer, you may always get the
+// original token stream back without undoing anything. Since the instructions
+// are queued up, you can easily simulate transactions and roll back any changes
+// if there is an error just by removing instructions. For example,
+
+//
+// CharStream input = new ANTLRFileStream("input");
+// TLexer lex = new TLexer(input);
+// CommonTokenStream tokens = new CommonTokenStream(lex);
+// T parser = new T(tokens);
+// TokenStreamRewriter rewriter = new TokenStreamRewriter(tokens);
+// parser.startRule();
+//
+
+//
+// Then in the rules, you can execute (assuming rewriter is visible):
+
+//
+// Token t,u;
+// ...
+// rewriter.insertAfter(t, "text to put after t");}
+// rewriter.insertAfter(u, "text after u");}
+// System.out.println(rewriter.getText());
+//
+
+//
+// You can also have multiple "instruction streams" and get multiple rewrites
+// from a single pass over the input. Just name the instruction streams and use
+// that name again when printing the buffer. This could be useful for generating
+// a C file and also its header file--all from the same buffer:
+
+//
+// rewriter.insertAfter("pass1", t, "text to put after t");}
+// rewriter.insertAfter("pass2", u, "text after u");}
+// System.out.println(rewriter.getText("pass1"));
+// System.out.println(rewriter.getText("pass2"));
+//
+
+//
+// If you don't use named rewrite streams, a "default" stream is used as the
+// first example shows.

+[fxamacker/cbor](https://github.com/fxamacker/cbor) is a library for encoding and decoding [CBOR](https://www.rfc-editor.org/info/std94) and [CBOR Sequences](https://www.rfc-editor.org/rfc/rfc8742.html).
+
+CBOR is a [trusted alternative](https://www.rfc-editor.org/rfc/rfc8949.html#name-comparison-of-other-binary-) to JSON, MessagePack, Protocol Buffers, etc. CBOR is an Internet Standard defined by [IETF STD 94 (RFC 8949)](https://www.rfc-editor.org/info/std94) and is designed to be relevant for decades.
+
+`fxamacker/cbor` is used in projects by Arm Ltd., EdgeX Foundry, Flow Foundation, Fraunhofer‑AISEC, IBM, Kubernetes[*](https://github.com/search?q=org%3Akubernetes%20fxamacker%2Fcbor&type=code), Let's Encrypt, Linux Foundation, Microsoft, Oasis Protocol, Red Hat[*](https://github.com/search?q=org%3Aopenshift+fxamacker%2Fcbor&type=code), Tailscale[*](https://github.com/search?q=org%3Atailscale+fxamacker%2Fcbor&type=code), Veraison[*](https://github.com/search?q=org%3Averaison+fxamacker%2Fcbor&type=code), [etc](https://github.com/fxamacker/cbor#who-uses-fxamackercbor).
+
+See [Quick Start](#quick-start) and [Releases](https://github.com/fxamacker/cbor/releases/). 🆕 `UnmarshalFirst` and `DiagnoseFirst` can decode CBOR Sequences. `MarshalToBuffer` and `UserBufferEncMode` accepts user-specified buffer.

+
+`fxamacker/cbor` is a CBOR codec in full conformance with [IETF STD 94 (RFC 8949)](https://www.rfc-editor.org/info/std94). It also supports CBOR Sequences ([RFC 8742](https://www.rfc-editor.org/rfc/rfc8742.html)) and Extended Diagnostic Notation ([Appendix G of RFC 8610](https://www.rfc-editor.org/rfc/rfc8610.html#appendix-G)).
+
+Features include full support for CBOR tags, [Core Deterministic Encoding](https://www.rfc-editor.org/rfc/rfc8949.html#name-core-deterministic-encoding), duplicate map key detection, etc.
+
+API is mostly same as `encoding/json`, plus interfaces that simplify concurrency and CBOR options.
+
+Design balances trade-offs between security, speed, concurrency, encoded data size, usability, etc.
+
+ 🔎 Highlights
+
+__🚀 Speed__
+
+Encoding and decoding is fast without using Go's `unsafe` package. Slower settings are opt-in. Default limits allow very fast and memory efficient rejection of malformed CBOR data.
+
+__🔒 Security__
+
+Decoder has configurable limits that defend against malicious inputs. Duplicate map key detection is supported. By contrast, `encoding/gob` is [not designed to be hardened against adversarial inputs](https://pkg.go.dev/encoding/gob#hdr-Security).
+
+Codec passed multiple confidential security assessments in 2022. No vulnerabilities found in subset of codec in a [nonconfidential security assessment](https://github.com/veraison/go-cose/blob/v1.0.0-rc.1/reports/NCC_Microsoft-go-cose-Report_2022-05-26_v1.0.pdf) prepared by NCC Group for Microsoft Corporation.
+
+__🗜️ Data Size__
+
+Struct tag options (`toarray`, `keyasint`, `omitempty`, `omitzero`) and field tag "-" automatically reduce size of encoded structs. Encoding optionally shrinks float64→32→16 when values fit.
+
+__:jigsaw: Usability__
+
+API is mostly same as `encoding/json` plus interfaces that simplify concurrency for CBOR options. Encoding and decoding modes can be created at startup and reused by any goroutines.
+
+Presets include Core Deterministic Encoding, Preferred Serialization, CTAP2 Canonical CBOR, etc.
+
+__📆 Extensibility__
+
+Features include CBOR [extension points](https://www.rfc-editor.org/rfc/rfc8949.html#section-7.1) (e.g. CBOR tags) and extensive settings. API has interfaces that allow users to create custom encoding and decoding without modifying this library.
+
+
+
+
+
+### Secure Decoding with Configurable Settings
+
+`fxamacker/cbor` has configurable limits, etc. that defend against malicious CBOR data.
+
+Notably, `fxamacker/cbor` is fast at rejecting malformed CBOR data.

+
+### Smaller Encodings with Struct Tag Options
+
+Struct tags automatically reduce encoded size of structs and improve speed.
+
+We can write less code by using struct tag options:
+- `toarray`: encode without field names (decode back to original struct)
+- `keyasint`: encode field names as integers (decode back to original struct)
+- `omitempty`: omit empty field when encoding
+- `omitzero`: omit zero-value field when encoding
+
+As a special case, struct field tag "-" omits the field.
+
+NOTE: When a struct uses `toarray`, the encoder will ignore `omitempty` and `omitzero` to prevent position of encoded array elements from changing. This allows decoder to match encoded elements to their Go struct field.
+
+
+
+> [!NOTE]
+> `fxamacker/cbor` can encode a 3-level nested Go struct to 1 byte!

+>
+> ### Tinygo
+>
+> Branch [feature/cbor-tinygo-beta](https://github.com/fxamacker/cbor/tree/feature/cbor-tinygo-beta) is based on fxamacker/cbor v2.7.0 and it can be compiled using tinygo v0.33 (also compiles with golang/go).
+>
+> It passes unit tests (with both go1.22 and tinygo v0.33) and is considered beta/experimental for tinygo.
+>
+> :warning: The `feature/cbor-tinygo-beta` branch does not get fuzz tested yet.
+>
+> Changes in this feature branch only affect tinygo compiled software. Summary of changes:
+> - default `DecOptions.MaxNestedLevels` is reduced to 16 (was 32). User can specify higher limit but 24+ crashes tests when compiled with tinygo v0.33.
+> - disabled decoding CBOR tag data to Go interface because tinygo v0.33 is missing needed feature.
+> - encoding error message can be different when encoding function type.
+>

+
+### Key Points
+
+This library can encode and decode CBOR (RFC 8949) and CBOR Sequences (RFC 8742).
+
+- __CBOR data item__ is a single piece of CBOR data and its structure may contain 0 or more nested data items.
+- __CBOR sequence__ is a concatenation of 0 or more encoded CBOR data items.
+
+Configurable limits and options can be used to balance trade-offs.
+
+- Encoding and decoding modes are created from options (settings).
+- Modes can be created at startup and reused.
+- Modes are safe for concurrent use.
+
+### Default Mode
+
+Package level functions only use this library's default settings.
+They provide the "default mode" of encoding and decoding.
+
+```go
+// API matches encoding/json for Marshal, Unmarshal, Encode, Decode, etc.
+b, err = cbor.Marshal(v) // encode v to []byte b
+err = cbor.Unmarshal(b, &v) // decode []byte b to v
+decoder = cbor.NewDecoder(r) // create decoder with io.Reader r
+err = decoder.Decode(&v) // decode a CBOR data item to v
+
+// v2.7.0 added MarshalToBuffer() and UserBufferEncMode interface.
+err = cbor.MarshalToBuffer(v, b) // encode v to b instead of using built-in buf pool.
+
+// v2.5.0 added new functions that return remaining bytes.
+
+// UnmarshalFirst decodes first CBOR data item and returns remaining bytes.
+rest, err = cbor.UnmarshalFirst(b, &v) // decode []byte b to v
+
+// DiagnoseFirst translates first CBOR data item to text and returns remaining bytes.
+text, rest, err = cbor.DiagnoseFirst(b) // decode []byte b to Diagnostic Notation text
+
+// NOTE: Unmarshal() returns ExtraneousDataError if there are remaining bytes, but
+// UnmarshalFirst() and DiagnoseFirst() allow trailing bytes.
+```
+
+> [!IMPORTANT]
+> CBOR settings allow trade-offs between speed, security, encoding size, etc.
+>
+> - Different CBOR libraries may use different default settings.
+> - CBOR-based formats or protocols usually require specific settings.
+>
+> For example, WebAuthn uses "CTAP2 Canonical CBOR" which is available as a preset.
+
+### Presets
+
+Presets can be used as-is or as a starting point for custom settings.
+
+```go
+// EncOptions is a struct of encoder settings.
+func CoreDetEncOptions() EncOptions // RFC 8949 Core Deterministic Encoding
+func PreferredUnsortedEncOptions() EncOptions // RFC 8949 Preferred Serialization
+func CanonicalEncOptions() EncOptions // RFC 7049 Canonical CBOR
+func CTAP2EncOptions() EncOptions // FIDO2 CTAP2 Canonical CBOR
+```
+
+Presets are used to create custom modes.
+
+### Custom Modes
+
+Modes are created from settings. Once created, modes have immutable settings.
+
+💡 Create the mode at startup and reuse it. It is safe for concurrent use.
+
+```Go
+// Create encoding mode.
+opts := cbor.CoreDetEncOptions() // use preset options as a starting point
+opts.Time = cbor.TimeUnix // change any settings if needed
+em, err := opts.EncMode() // create an immutable encoding mode
+
+// Reuse the encoding mode. It is safe for concurrent use.
+
+// API matches encoding/json.
+b, err := em.Marshal(v) // encode v to []byte b
+encoder := em.NewEncoder(w) // create encoder with io.Writer w
+err := encoder.Encode(v) // encode v to io.Writer w
+```
+
+Default mode and custom modes automatically apply struct tags.
+
+### User Specified Buffer for Encoding (v2.7.0)
+
+`UserBufferEncMode` interface extends `EncMode` interface to add `MarshalToBuffer()`. It accepts a user-specified buffer instead of using built-in buffer pool.
+
+```Go
+em, err := myEncOptions.UserBufferEncMode() // create UserBufferEncMode mode
+
+var buf bytes.Buffer
+err = em.MarshalToBuffer(v, &buf) // encode v to provided buf
+```
+
+### Struct Tags
+
+Struct tag options (`toarray`, `keyasint`, `omitempty`, `omitzero`) reduce encoded size of structs.
+
+As a special case, struct field tag "-" omits the field.
+
+ 🔎 Example encoding with struct field tag "-"
+
+https://go.dev/play/p/aWEIFxd7InX
+
+```Go
+// https://github.com/fxamacker/cbor/issues/652
+package main
+
+import (
+ "encoding/json"
+ "fmt"
+
+ "github.com/fxamacker/cbor/v2"
+)
+
+// The `cbor:"-"` tag omits the Type field when encoding to CBOR.
+type Entity struct {
+ _ struct{} `cbor:",toarray"`
+ ID uint64 `json:"id"`
+ Type string `cbor:"-" json:"typeOf"`
+ Name string `json:"name"`
+}
+
+func main() {
+ entity := Entity{
+ ID: 1,
+ Type: "int64",
+ Name: "Identifier",
+ }
+
+ c, _ := cbor.Marshal(entity)
+ diag, _ := cbor.Diagnose(c)
+ fmt.Printf("CBOR in hex: %x\n", c)
+ fmt.Printf("CBOR in edn: %s\n", diag)
+
+ j, _ := json.Marshal(entity)
+ fmt.Printf("JSON: %s\n", string(j))
+
+ fmt.Printf("JSON encoding is %d bytes\n", len(j))
+ fmt.Printf("CBOR encoding is %d bytes\n", len(c))
+
+ // Output:
+ // CBOR in hex: 82016a4964656e746966696572
+ // CBOR in edn: [1, "Identifier"]
+ // JSON: {"id":1,"typeOf":"int64","name":"Identifier"}
+ // JSON encoding is 45 bytes
+ // CBOR encoding is 13 bytes
+}
+```
+
+
+
+ 🔎 Example encoding 3-level nested Go struct to 1 byte CBOR
+
+https://go.dev/play/p/YxwvfPdFQG2
+
+```Go
+// Example encoding nested struct (with omitempty tag)
+// - encoding/json: 18 byte JSON
+// - fxamacker/cbor: 1 byte CBOR
+package main
+
+import (
+ "encoding/hex"
+ "encoding/json"
+ "fmt"
+
+ "github.com/fxamacker/cbor/v2"
+)
+
+type GrandChild struct {
+ Quux int `json:",omitempty"`
+}
+
+type Child struct {
+ Baz int `json:",omitempty"`
+ Qux GrandChild `json:",omitempty"`
+}
+
+type Parent struct {
+ Foo Child `json:",omitempty"`
+ Bar int `json:",omitempty"`
+}
+
+func cb() {
+ results, _ := cbor.Marshal(Parent{})
+ fmt.Println("hex(CBOR): " + hex.EncodeToString(results))
+
+ text, _ := cbor.Diagnose(results) // Diagnostic Notation
+ fmt.Println("DN: " + text)
+}
+
+func js() {
+ results, _ := json.Marshal(Parent{})
+ fmt.Println("hex(JSON): " + hex.EncodeToString(results))
+
+ text := string(results) // JSON
+ fmt.Println("JSON: " + text)
+}
+
+func main() {
+ cb()
+ fmt.Println("-------------")
+ js()
+}
+```
+
+Output (DN is Diagnostic Notation):
+```
+hex(CBOR): a0
+DN: {}
+-------------
+hex(JSON): 7b22466f6f223a7b22517578223a7b7d7d7d
+JSON: {"Foo":{"Qux":{}}}
+```
+
+
+
+
+
+ 🔎 Example using struct tag options
+
+
+
+
+
+Struct tag options simplify use of CBOR-based protocols that require CBOR arrays or maps with integer keys.
+
+### CBOR Tags
+
+CBOR tags are specified in a `TagSet`.
+
+Custom modes can be created with a `TagSet` to handle CBOR tags.
+
+```go
+em, err := opts.EncMode() // no CBOR tags
+em, err := opts.EncModeWithTags(ts) // immutable CBOR tags
+em, err := opts.EncModeWithSharedTags(ts) // mutable shared CBOR tags
+```
+
+`TagSet` and modes using it are safe for concurrent use. Equivalent API is available for `DecMode`.
+
+ 🔎 Example using TagSet and TagOptions
+
+```go
+// Use signedCWT struct defined in "Decoding CWT" example.
+
+// Create TagSet (safe for concurrency).
+tags := cbor.NewTagSet()
+// Register tag COSE_Sign1 18 with signedCWT type.
+tags.Add(
+ cbor.TagOptions{EncTag: cbor.EncTagRequired, DecTag: cbor.DecTagRequired},
+ reflect.TypeOf(signedCWT{}),
+ 18)
+
+// Create DecMode with immutable tags.
+dm, _ := cbor.DecOptions{}.DecModeWithTags(tags)
+
+// Unmarshal to signedCWT with tag support.
+var v signedCWT
+if err := dm.Unmarshal(data, &v); err != nil {
+ return err
+}
+
+// Create EncMode with immutable tags.
+em, _ := cbor.EncOptions{}.EncModeWithTags(tags)
+
+// Marshal signedCWT with tag number.
+if data, err := em.Marshal(v); err != nil {
+ return err
+}
+```
+
+
+
+👉 `fxamacker/cbor` allows user apps to use almost any current or future CBOR tag number by implementing `cbor.Marshaler` and `cbor.Unmarshaler` interfaces.
+
+Basically, `MarshalCBOR` and `UnmarshalCBOR` functions can be implemented by user apps and those functions will automatically be called by this CBOR codec's `Marshal`, `Unmarshal`, etc.
+
+The following [example](https://github.com/fxamacker/cbor/blob/master/example_embedded_json_tag_for_cbor_test.go) shows how to encode and decode a tagged CBOR data item with tag number 262. The tag content is a JSON object "embedded" as a CBOR byte string (major type 2).
+
+ 🔎 Example using Embedded JSON Tag for CBOR (tag 262)
+
+```go
+// https://github.com/fxamacker/cbor/issues/657
+
+package cbor_test
+
+// NOTE: RFC 8949 does not mention tag number 262. IANA assigned
+// CBOR tag number 262 as "Embedded JSON Object" specified by the
+// document Embedded JSON Tag for CBOR:

+// "Tag 262 can be applied to a byte string (major type 2) to indicate
+// that the byte string is a JSON Object. The length of the byte string
+// indicates the content."
+//

+### Functions and Interfaces
+
+ 🔎 Functions and interfaces at a glance
+
+Common functions with same API as `encoding/json`:
+- `Marshal`, `Unmarshal`
+- `NewEncoder`, `(*Encoder).Encode`
+- `NewDecoder`, `(*Decoder).Decode`
+
+NOTE: `Unmarshal` will return `ExtraneousDataError` if there are remaining bytes
+because RFC 8949 treats CBOR data item with remaining bytes as malformed.
+- 💡 Use `UnmarshalFirst` to decode first CBOR data item and return any remaining bytes.
+
+Other useful functions:
+- `Diagnose`, `DiagnoseFirst` produce human-readable [Extended Diagnostic Notation](https://www.rfc-editor.org/rfc/rfc8610.html#appendix-G) from CBOR data.
+- `UnmarshalFirst` decodes first CBOR data item and return any remaining bytes.
+- `Wellformed` returns true if the CBOR data item is well-formed.
+
+Interfaces identical or comparable to Go `encoding` packages include:
+`Marshaler`, `Unmarshaler`, `BinaryMarshaler`, and `BinaryUnmarshaler`.
+
+The `RawMessage` type can be used to delay CBOR decoding or precompute CBOR encoding.
+
+
+
+### Security Tips
+
+🔒 Use Go's `io.LimitReader` to limit size when decoding very large or indefinite size data.
+
+Default limits may need to be increased for systems handling very large data (e.g. blockchains).
+
+`DecOptions` can be used to modify default limits for `MaxArrayElements`, `MaxMapPairs`, and `MaxNestedLevels`.
+
+## Status
+
+[v2.9.0](https://github.com/fxamacker/cbor/releases/tag/v2.9.0) (Jul 13, 2025) improved interoperability/transcoding between CBOR & JSON, refactored tests, and improved docs.
+- Add opt-in support for `encoding.TextMarshaler` and `encoding.TextUnmarshaler` to encode and decode from CBOR text string.
+- Add opt-in support for `json.Marshaler` and `json.Unmarshaler` via user-provided transcoding function.
+- Update docs for TimeMode, Tag, RawTag, and add example for Embedded JSON Tag for CBOR.
+
+v2.9.0 passed fuzz tests and is production quality.
+
+The minimum version of Go required to build:
+- v2.8.0 and newer releases require go 1.20+.
+- v2.7.1 and older releases require go 1.17+.
+
+For more details, see [release notes](https://github.com/fxamacker/cbor/releases).
+
+### Prior Releases
+
+[v2.8.0](https://github.com/fxamacker/cbor/releases/tag/v2.8.0) (March 30, 2025) is a small release primarily to add `omitzero` option to struct field tags and fix bugs. It passed fuzz tests (billions of executions) and is production quality.
+
+[v2.7.0](https://github.com/fxamacker/cbor/releases/tag/v2.7.0) (June 23, 2024) adds features and improvements that help large projects (e.g. Kubernetes) use CBOR as an alternative to JSON and Protocol Buffers. Other improvements include speedups, improved memory use, bug fixes, new serialization options, etc. It passed fuzz tests (5+ billion executions) and is production quality.
+
+[v2.6.0](https://github.com/fxamacker/cbor/releases/tag/v2.6.0) (February 2024) adds important new features, optimizations, and bug fixes. It is especially useful to systems that need to convert data between CBOR and JSON. New options and optimizations improve handling of bignum, integers, maps, and strings.
+
+[v2.5.0](https://github.com/fxamacker/cbor/releases/tag/v2.5.0) was released on Sunday, August 13, 2023 with new features and important bug fixes. It is fuzz tested and production quality after extended beta [v2.5.0-beta](https://github.com/fxamacker/cbor/releases/tag/v2.5.0-beta) (Dec 2022) -> [v2.5.0](https://github.com/fxamacker/cbor/releases/tag/v2.5.0) (Aug 2023).
+
+__IMPORTANT__: 👉 Before upgrading from v2.4 or older release, please read the notable changes highlighted in the release notes. v2.5.0 is a large release with bug fixes to error handling for extraneous data in `Unmarshal`, etc. that should be reviewed before upgrading.
+
+See [v2.5.0 release notes](https://github.com/fxamacker/cbor/releases/tag/v2.5.0) for list of new features, improvements, and bug fixes.
+
+See ["Version and API Changes"](https://github.com/fxamacker/cbor#versions-and-api-changes) section for more info about version numbering, etc.

+
+## Who uses fxamacker/cbor
+
+`fxamacker/cbor` is used in projects by Arm Ltd., Berlin Institute of Health at Charité, Chainlink, Confidential Computing Consortium, ConsenSys, EdgeX Foundry, F5, Flow Foundation, Fraunhofer‑AISEC, IBM, Kubernetes, Let's Encrypt (ISRG), Linaro, Linux Foundation, Matrix.org, Microsoft, National Cybersecurity Agency of France (govt), Netherlands (govt), Oasis Protocol, Red Hat OpenShift, Smallstep, Tailscale, Taurus SA, TIBCO, Veraison, and others.
+
+`fxamacker/cbor` passed multiple confidential security assessments in 2022. A [nonconfidential security assessment](https://github.com/veraison/go-cose/blob/v1.0.0-rc.1/reports/NCC_Microsoft-go-cose-Report_2022-05-26_v1.0.pdf) (prepared by NCC Group for Microsoft Corporation) assessed a subset of fxamacker/cbor v2.4.
+
+## Standards
+
+`fxamacker/cbor` is a CBOR codec in full conformance with [IETF STD 94 (RFC 8949)](https://www.rfc-editor.org/info/std94). It also supports CBOR Sequences ([RFC 8742](https://www.rfc-editor.org/rfc/rfc8742.html)) and Extended Diagnostic Notation ([Appendix G of RFC 8610](https://www.rfc-editor.org/rfc/rfc8610.html#appendix-G)).
+
+Notable CBOR features include:
+
+| CBOR Feature | Description |
+| :--- | :--- |
+| CBOR tags | API supports built-in and user-defined tags. |
+| Preferred serialization | Integers encode to fewest bytes. Optional float64 → float32 → float16. |
+| Map key sorting | Unsorted, length-first (Canonical CBOR), and bytewise-lexicographic (CTAP2). |
+| Duplicate map keys | Always forbid for encoding and option to allow/forbid for decoding. |
+| Indefinite length data | Option to allow/forbid for encoding and decoding. |
+| Well-formedness | Always checked and enforced. |
+| Basic validity checks | Optionally check UTF-8 validity and duplicate map keys. |
+| Security considerations | Prevent integer overflow and resource exhaustion (RFC 8949 Section 10). |
+
+Known limitations are noted in the [Limitations section](#limitations).
+
+Go nil values for slices, maps, pointers, etc. are encoded as CBOR null. Empty slices, maps, etc. are encoded as empty CBOR arrays and maps.
+
+Decoder checks for all required well-formedness errors, including all "subkinds" of syntax errors and too little data.
+
+After well-formedness is verified, basic validity errors are handled as follows:
+
+* Invalid UTF-8 string: Decoder has option to check and return invalid UTF-8 string error. This check is enabled by default.
+* Duplicate keys in a map: Decoder has options to ignore or enforce rejection of duplicate map keys.
+
+When decoding well-formed CBOR arrays and maps, decoder saves the first error it encounters and continues with the next item. Options to handle this differently may be added in the future.
+
+By default, decoder treats time values of floating-point NaN and Infinity as if they are CBOR Null or CBOR Undefined.
+
+__Click to expand topic:__
+
+
+ 🔎 Duplicate Map Keys
+
+This library provides options for fast detection and rejection of duplicate map keys based on applying a Go-specific data model to CBOR's extended generic data model in order to determine duplicate vs distinct map keys. Detection relies on whether the CBOR map key would be a duplicate "key" when decoded and applied to the user-provided Go map or struct.
+
+`DupMapKeyQuiet` turns off detection of duplicate map keys. It tries to use a "keep fastest" method by choosing either "keep first" or "keep last" depending on the Go data type.
+
+`DupMapKeyEnforcedAPF` enforces detection and rejection of duplidate map keys. Decoding stops immediately and returns `DupMapKeyError` when the first duplicate key is detected. The error includes the duplicate map key and the index number.
+
+APF suffix means "Allow Partial Fill" so the destination map or struct can contain some decoded values at the time of error. It is the caller's responsibility to respond to the `DupMapKeyError` by discarding the partially filled result if that's required by their protocol.
+
+
+
+
+ 🔎 Tag Validity
+
+This library checks tag validity for built-in tags (currently tag numbers 0, 1, 2, 3, and 55799):
+
+* Inadmissible type for tag content
+* Inadmissible value for tag content
+
+Unknown tag data items (not tag number 0, 1, 2, 3, or 55799) are handled in two ways:
+
+* When decoding into an empty interface, unknown tag data item will be decoded into `cbor.Tag` data type, which contains tag number and tag content. The tag content will be decoded into the default Go data type for the CBOR data type.
+* When decoding into other Go types, unknown tag data item is decoded into the specified Go type. If Go type is registered with a tag number, the tag number can optionally be verified.
+
+Decoder also has an option to forbid tag data items (treat any tag data item as error) which is specified by protocols such as CTAP2 Canonical CBOR.
+
+For more information, see [decoding options](#decoding-options-1) and [tag options](#tag-options).
