Sources and the conflicts register
Two help trees, one schema, one kit specification, the vendored docs, the release notes, and one capture kit, with a ruling for every conflict a section touches.
The pin is sbx 0.47.0 and docker-agent 1.149.0. The agent file schema is at version 16, and the Sandbox Kit Spec at milestone v3.0.0-m.8. The pin date is 2026-10-07, and the facts were verified on 2026-10-08. Every file named below is vendored in the repository, and its README records its origin, commit, line count, and license.

The ranked sources
When two sources disagree, the higher one wins and the section says so. The table repeats the ranking of the manual with its source keys.
| Rank | Source | Source key | Used for |
|---|---|---|---|
| 1 | the help text that sbx 0.47.0 and docker-agent 1.149.0 print | help-sbx, help-agent with the command | every command, flag, default, and path |
| 2 | the agent file schema at v1.149.0 | schema with the definition | every key, type, and default of the agent file |
| 3 | Sandbox Kit Spec v3 at tag v3.0.0-m.8 | kitspec with the section, kitspec-main for unreleased changes, kitcap for a capability page | the kit descriptor and each capability |
| 4 | the Docker documentation, fetched 2026-10-08 | docs-sbx, docs-agent, docs-dmr, docs-mcp, docs-sbx-api, docs-desktop with the page | rules and limits the help text does not state |
| 5 | the release notes | rel-sbx, rel-agent with the version | when a behaviour appeared, changed, or was removed |
| 6 | Docker blog posts and talks, through the research files | blog, talk with a date, declared null | history and positioning only, never a rule |
| 7 | the capture kit | the captured output | every command output, file, and record shown |

The conflicts register
The conflicts register holds 122 conflicts, C1 to C122, in nine groups, and 30 pieces of stale advice, S1 to S30. The table below keeps every C row that a section entry of the plan cites or whose ruling names a section. That is 94 rows, each with the ruling the manual follows. The 28 rows that no section uses are cut to keep the table short, and the next table names them by group. Their substance appears in the S rows below or in the register itself. Kind is the register's own label.
| Group | Rows cut |
|---|---|
| A, sbx | C1, C2, C3, C5, C6, C8, C10, C11, C14, C22, C23, C24, C30 |
| B, docker-agent | C55, C57, C74 |
| C, Docker Model Runner | C78, C80, C81, C82, C85 |
| D, MCP gateway and Toolkit | C86, C87 |
| E, Compose | C94, C95, C97 |
| F, Offload | C100 |
| G, Cloud Sandboxes | C102 |
| Id | Kind | What disagrees | Ruling |
|---|---|---|---|
| C4 | talk vs docs | libkrun or Firecracker as the VMM, against a VMM Docker wrote | A VMM Docker wrote, on Hypervisor.framework, WHP, and KVM. libkrun stays unverified |
| C7 | removed | API keys exported in the shell, against the secret store since v0.35.0 | Secrets come from the secret store. -e KEY is a plain variable, not a secret |

| C12 | docs vs repo | a 512 MB default kit volume, against 20 GiB in the spec docs | Both numbers with their sources, no single default |
| C13 | docs vs CLI | v1, v2, and v3 kits, against sbx kit commands that name only v1 and v2 | The sbx kit artifact commands are v1 and v2 tooling. A v3 kit is an OCI image built with Docker tooling |

| C21 | docs vs CLI | 11 built-in secret services in the docs, 13 in the CLI | 13 services |
| C25 | renamed | the plugin name rule, against the sbx rule | The sbx rule: 2 to 63 characters, letters, digits, hyphens, periods, default reserved |
| C26 | undocumented | host.docker.internal:3128 or gateway.docker.internal:3128, against docs with no address | The address and variables the capture shows |
| C27 | blog stale | UDP and ICMP blocked for good, against UDP behind feature.udp-egress | UDP rules exist behind the experimental flag. ICMP is blocked. DNS is policy-controlled |

| C29 | talk vs docs | near-instant start, against seconds | The manual's own timing on one machine, no vendor number |
| C31 | removed | docker sandbox exec -d, against sbx exec -d not supported | Said so in 2.2 |
| C32 | renamed | docker sandbox save into the host daemon, against the runtime image store | Said so in 2.3 and the migration table |

| C42 | docs vs CLI | ssh <name>.sbx through a managed block, against sbx setup ssh details | The help text facts |
| C43 | docs vs CLI | templates and kits as different things, against a kit as the positional agent | Three words defined once in 2.1 |

| C106 | blog stale | the sandbox primitive inside Kubernetes, against no other mention | Omitted |
| C107 | removed | the plugin still in Desktop, against removal in 4.80.0 | The error text the capture shows |
| C108 | removed | --mount-docker-socket, --load-local-template, --pull-template, against none in sbx | Migration rows S1 to S4 |
| C109 | renamed | network proxy flags, against policy subcommands with no bypass | Migration rows S10 and S11, bypass with no replacement found |

| C112 | removed | keys from the daemon environment and state under ~/.docker/sandboxes/, against the sbx store | One table in 7.3 |
| C113 | docs vs CLI | index annotations that the frontend promotes (kitspec §9.3), against an index with an attestation manifest and no annotations | 4.1 prints both. The annotations sit on the platform manifest (28-index.json, 28-manifest.json), which a consumer reads when the index has none |
| C114 | docs vs CLI | a floating docker/sandbox-kit:3 that never moves for a milestone, against a resolve to 3.0.0-m.8 | 4.1 prints both (28-buildx.txt). A build that needs the same frontend every time names the exact version tag |
| C115 | docs vs CLI | docker buildx build -f kit.yaml --push as the publish command, against a schema 2 manifest with no annotations from the default docker driver | 4.1 says to build with a docker-container builder (28-manifest-docker-driver.json, 28-manifest.json). An image without the annotation is not a kit |
| C116 | docs vs CLI | a local source directory passed to sbx during development, against sbx kit inspect failing on Desktop 4.94.0 | 4.1 prints both (13-kit-v3-inspect.txt, 28-kit-inspect-source.txt). No capture ran sbx run on a directory |
| C117 | docs vs CLI | source builds in the sbx-kit-builder sandbox, against a build through the host Docker daemon and a builder "not created" | 4.1 and 4.3 print the help line and the status (13-kit-builder-status.txt). Where a successful source build runs stays unstated |
| C118 | docs vs repo | agent file config version 15 as current, against a schema enum to "16" and captured files that load | "16" from the schema (5.2, R.4). The docs page still names 15 |
| C119 | docs vs CLI | session titles made from the first message, against five sessions titled Running agent | 5.6 prints the five rows (21-session-db.txt) |
| C120 | docs vs CLI | a skill name and mode lists that A2A 1.0.1 requires, against a card with an empty skill name and two empty mode lists | 6.3 prints the card against the rules (23-agent-card.json). A client accepts the empty values |
| C121 | docs vs CLI | "A2A artifact support not yet integrated", against a task whose artifacts hold the answer | 6.3 says the capture contradicts the limitation (23-a2a.http) |
| C122 | docs vs CLI | a release note that points to docker sbx, against a notice that points to the product page and a plugin list that still shows sandbox v0.13.0 | 7.3 prints the notice (29-docker-sandbox.txt, 29-docker-plugins.txt). The plugin entry stays, and the command only prints the notice |
