No verdict is implied.`, and `audit --host` reported Claude Code coverage `complete`. Host-grants `0.9` (extended in place) now publishes `command_setting` grants for `statusLine`, `subagentStatusLine`, `fileSuggestion`, `apiKeyHelper`, `otelHeadersHelper`, `awsAuthRefresh` and `awsCredentialExport` (`high`, the command shown as a hook's is: name, digest and shape, never text) and `env` grants for endpoint, trust and loader names (`*_BASE_URL`, OpenTelemetry exporter endpoints, the proxies, `NODE_EXTRA_CA_CERTS`, `NODE_TLS_REJECT_UNAUTHORIZED`, `NODE_OPTIONS`, `BASH_ENV`, `CLAUDE_CODE_SHELL_PREFIX`, `LD_PRELOAD`, `DYLD_INSERT_LIBRARIES`; `high`, the value digested and never published), so adding one is a `⚠ high added` row and editing one a `changed` row naming the two digests. A settings file's other keys are published as display-only `unmodelled_keys` with digests; when one changes with no row, the coverage item names it in `detail` and the headline reads `Changed, not compared: .claude/settings.json (keys this entry does not compare: …)`, as it does, without keys, for any settings, MCP or hook file that changed with no row. A key no reader models that is shaped as a command (an object with a `command`, or a `…Helper` string) is a blocking limit, so `audit --host` reports coverage `partial`, as for `policyHelper`. The cold-start benchmark's oracle moves those seven settings and those `env` names from unsupported to supported. Migration: [STABILITY.md](STABILITY.md#host-commands-env-1027). (#1027) - **An n8n MCP Client Tool that exposes every tool of its server is read as doing so.** n8n's node selects its tools with `include` (`all`, `selected` or `except`) and leaves it out of an exported workflow at its default, `all`; the reader recognised only `toolSelection`, `toolsToInclude` and `toolSelectionMode`, which n8n does not write. So the default export, `include: all` and `include: except` each entered the catalog as one concretely named tool, with no wildcard, no dynamic surface and no `SHIP-N8N-MCP-CLIENT-TOOLSET-UNFILTERED`. Each is now one `.*` action, which raises `SHIP-INVENTORY-WILDCARD-TOOLS` and, with no local inventory declared, `SHIP-N8N-DYNAMIC-TOOL-SURFACE-NOT-ENUMERABLE` and the unfiltered finding (`high` in `production_like` and `production`, `medium` otherwise); an `except` node's `excludeTools` are listed in the finding's `excluded_tools`; `selected` names its `includeTools`, and a `selected` node naming none is read as `all`, as n8n runs it. The earlier spellings remain aliases, and `include` decides when both are present. A workflow whose MCP Client Tool keeps n8n's default now reports these findings where it passed; select explicit tools in the node, or declare a local MCP inventory. Migration: [STABILITY.md](STABILITY.md#mcp-reader-conformance-1025). (#1025) - **`SHIP-MCP-ENV-SECRET-PASSTHROUGH` counts a secret an MCP server forwards by name, not only an `env` entry.** A secret-like variable in Codex's `env_vars` list or `env_http_headers`, any `bearer_token_env_var`, and a `${NAME}` reference in a `headers` value (`.mcp.json`) now fire the finding (an editor's `${env:NAME}` is read as `NAME` there and in `env`, and a prompted `${input:…}` names no variable) and add to the server's risk score as an `env` entry always did. A credential-named header (`Authorization`) counts the variable it carries whatever that variable is called, and a value written where a variable name belongs is redacted in the evidence, not echoed. (#1025) - **A `codex_config` source names the other hosts' MCP config files it does not read.** Its coverage said it read `.mcp.json`, `.codex/config.toml` "and the other host MCP config files" under its root; it reads only the first two. A `.cursor/mcp.json` or `.vscode/mcp.json` there is now named in a source warning, so a workspace whose servers live only in one no longer passes silently, and the coverage text in [`docs/determinism-boundary.md`](docs/determinism-boundary.md) names exactly the files read and the files named.

Every field is read from the drift payload the engine already produces — `risk` is the engine's severity and `expansion_signals` is the engine's word on widening — so there is no second implementation to drift. A `permission_mode` or `sandbox` row names the setting and its value as the file spells it (`enableAllProjectMcpServers: true`, `defaultMode: dontAsk`), recovered from the grant's published value and digest, and a Claude Code setting's `why` is the basis the engine's one setting table (`core/host_settings.py`) records for the value; that table also rates the grant and `check`'s violation, so a row's severity and the violation's risk give one answer (#827, `tests/test_prompt_disabling_settings.py`). `verify`/PR and `check` reuse the host comparator (#684, `tests/test_manifest_free_pr_rows.py`), and the source name each named reusable-workflow secret refers to, also non-widening, with a redacting name or target refused rather than compared, and an unreadable value neither compared nor named on this surface — only the host inventory and `audit --host` name its `job/destination`, as on `1.0.0` (#693, `tests/test_reusable_workflow_secret_mappings.py`); check retains argument redaction, except that an allow rule the engine rates as reaching a [documented arbitrary-code launcher](engineering/exec-equivalent-permissions.md) is shown in table text (`Bash(npx *)`, or a wider rule's own prefix of it, `Bash(python3 *)`) and never with a user operand, the one rating `diff`, `audit --host`, `verify` and the PR comment also carry, and its existing local-policy control (#824, `tests/test_exec_equivalent_permissions.py`). Missing comparison evidence never supplies empty comparable rows. A Claude Code permission rule row's `direction`, `expands` and `why` read the engine's one rule model (`core/claude_permission_rules.py`), the reading drift's `expansion_signals` and `check`'s violations come from, so a covered, respelled, never-consulted or carve-out rule gets one answer on every route (#918, #941, #969, #974, #938, `tests/test_claude_permission_rule_model.py`). A permission rule's cell is the text the settings reader published, never re-redacted here: a URL in it keeps its closing delimiter and trailing wildcard and withholds its path, query, fragment and userinfo, with a digest where it withholds a URL part, so two rules that publish alike stay two rows and two changes on every route (#922, `tests/test_permission_rule_url_redaction.py`). Default host mode only (`--application` is registered separately below); workflow rows compare effective writes and reusable secret recipients (#685, `tests/test_workflow_capability_diff.py`), with the privileged `pull_request_target` event stated apart from the job token scopes, a calling job's permissions printed as a ceiling whose reach the engine read from a same-repository callee's own permissions (`callee_permissions`, `callee_write_scopes` on the grant), and an inheriting call re-pinned to another reference of the same workflow a reference change rather than a new recipient, all read off the grant and `expansion_signals` the engine published (#920, #921, #924, `tests/test_actions_token_scope.py`), and each job's remote step action references, as a non-widening change (#771, `tests/test_workflow_step_action_references.py`); and each job's agent launches — a documented agent action's permission inputs, the permission flags of a `run:` that is one plain `claude -p` / `codex exec` command — and checkout refs, compared as text, as a change unless the job gains a documented widening rule, which the engine names in `expansion_signals` (`workflow_agent_widened_*`) — a rule read only from text the engine reads exactly (no shell is parsed; an argument input that is not a plain list of words is compared by a digest and read for no rule), and a gain the engine does not claim (a rule moved in from a job the launch left, one an unread step of the job rewritten as a read launch may already have met, or one the job's launch held before in an expression or an unread argument input) named in the `why` from the same engine function, never counted — with a note on a workflow row naming the untrusted-input trigger, write scopes, secrets and pull request checkout beside each agent step, read off the grant the engine published and moving no direction; an unread `run:` agent step (never compared, so never a row), an unreadable value or a setting published redacted is named only by the host inventory and `audit --host`, as for an unread secret value, an unread argument input or an unresolved launch is named there and in the `why` of a row reporting its launch, and a checkout ref holding credential-shaped text is refused as a redacting step reference is (#823, `tests/test_workflow_agent_launches.py`); every job id, step label, trigger and scope name those rows print is the label the engine published once where it built the grant, redacted, never re-derived here; `check`'s workflow evidence is derived from the raw declarations, which it still compares, and redacts job and scope names by the same rule; two distinct job ids or triggers in one workflow, or scope names in one `permissions` mapping, that publish alike are refused rather than compared, so while such a workflow exists `check` refuses on every run even when it is unchanged (#802, `tests/test_workflow_label_redaction.py`); artifact-only edits remain separate evidence. Tool-source subjects are #655. Where a partial or experimental surface is byte-identical on both sides, `diff` and `verify` compare the rest and name it in `unchanged_limits`; `check` keeps refusing, because its boundary result cannot carry a limit yet (#721). A surface the reader reaches through an in-tree link it reads through qualifies only when that link, a link with the same text at each link on the way, and the file it lands on, the same blob at the same path, are both unchanged, read from the base's Git tree entries against a commit's or, without following any link, the working tree's; any change to either is treated as before. The same proof decides which shared plugin-reference limits `check` leaves out, so behind such a link `check` compares, and publishes the rows it finds, exactly as for a limit at its own path, and a comparison `partial` only because of such a limit is `comparable` with it in `unchanged_limits` (#822, `tests/test_linked_unchanged_limits.py`). An added or changed MCP row's `why` appends a launch-source note — `launch source is mutable`, or `launch source moved from pinned … to mutable …` when both sides establish a pin — read from the `launch_source` the engine published on the grant by a bounded declaration grammar ([mcp-launch-source-notes](engineering/mcp-launch-source-notes.md)); grant equality, the inventory digests and saved baselines leave that fact out, so the note adds no row and moves no direction, `expands`, severity, expansion signal or `check` decision (#825, `tests/test_mcp_launch_source.py`). An `npx` package named with no version specifier reads instead `package spec has no exact version; launch resolution not established: npx may resolve a local project dependency or fall back to the registry/cache`, from the display-only `resolution: local_project_or_registry` the engine published beside the pin (host-grants `0.9`), as npm documents `npx` resolving such a name; no `package.json`, lockfile or cache is read, and nothing else moves (#933). A changed MCP row names the plain environment-variable names its `env_vars` list gained and lost (`env_vars names +CODEX_SECURITY_PLUGIN_ROOT`, or `in a different order`) from the display-only `env_var_names` the engine published on the grant (host-grants `0.9`), never a value; grant equality, the inventory digests and saved baselines leave it out, so it adds no row and moves no direction, `expands`, severity, expansion signal or `check` decision (#795, `tests/test_mcp_env_var_names.py`). A removed MCP row reads `the server is no longer declared in this source; whether it is still offered through a changed declaration this entry does not read is not established` instead of `an MCP tool surface is no longer offered to the agent` when the same comparison's #821 discovery names a changed, unread input that may declare MCP servers in the head (a plugin manifest's `mcpServers`, a manifest that does not parse, a plugin's `mcp.json`) in the same plugin scope and for the same host; the input is never read, matched or paired, keeps its coverage item, and no direction, `expands`, severity or `check` decision moves; `check` lists the changed files for it only when a server is removed and a provided diff states only the files it touches (#929, `tests/test_mcp_row_bounded_wording.py`). An MCP row's subject names the host the engine published its grant under, which for a `.mcp.json` is the host whose declaration selects it (#936): `codex` for a Codex plugin's, and no host for one the inventory published under `unknown`, whose `why` then says the host is not established; it restates the inventory's attribution, which `check`'s `affected_hosts` and `host_coverage` read too, and moves no direction, `expands`, severity, expansion signal or `check` decision (`tests/test_mcp_host_attribution.py`). A hook row's `why` states the grant's loading basis, read from its published `source`, `access` and `risk` by the engine's `hook_loading_basis`; only a hook the host loads for this project earns an expansion signal — one a settings layer declares, or one a plugin selects that the repository's project settings enable from an in-repository marketplace — so a declared-only hook, or one a plugin selects without that enablement, is a row and never an expansion, and a removal names no basis (#714). An added or changed Claude Code `PreToolUse` hook row whose basis is host configuration or a project-enabled plugin appends `inline allow auto-approves matched tool calls without a prompt (matcher …)` when a handler's published `inline_allow` is true — the engine's reading of a literal, unconditional allow on a broad matcher by a bounded declaration grammar ([inline-hook-allow-notes](engineering/inline-hook-allow-notes.md)), which grant equality, the inventory digests and saved baselines leave out — so the note adds no row and moves no direction, `expands`, severity, expansion signal or `check` decision (#826, `tests/test_inline_hook_allow.py`). A Claude Code tool-event hook row reads the `matcher_reach` the engine published on each handler (host-grants `0.9`): a hook every one of whose handlers is `no_tool_name` — its declared matcher, read by a bounded parser that never runs it, can match no built-in or MCP tool name, as with `Bash(git push*)` — earns no expansion signal, and its row is `declares a hook no tool call can trigger` and names the matcher, as does a row whose hook also has handlers that can run; the engine counts the handlers a tool call may run to decide a widening, so `diff`, `verify`, the PR comment, `check`'s rows and drift give one answer, and `check`'s decision does not move (#940, `tests/test_hook_matcher_reach.py`). A hook row also names a handler's exec-form `args` — the first argument shaped as a relative script path that no redaction rule rewrites, alone or after the arguments before it, and a digest of the rest, never other argument text — and the documented `type`, `async`, `asyncRewake`, `shell` and `once` settings it declares, before and after, read from the display-only `handlers` the engine published (host-grants `0.9`), which grant equality, the inventory digests and saved baselines leave out, so the field difference reaches the text and `review.changes[].change` and moves no row, direction, severity, expansion signal, loading basis or `check` decision, and a change confined to a field still not published, such as `if` or `statusMessage`, still says it is not shown (#972, #971, `tests/test_hook_args_and_settings.py`). A hook row also describes a changed inline command by the structure the engine published on its display-only `command.shape` (host-grants `0.9`) — the plain-token programs at its command positions, counts of commands, pipes, substitutions, control-flow keywords and quoted strings, its file redirects and a script path, never an argument, quoted string, URL or absolute path — or, when the engine published `shape_limit` instead, says the command is not described, the digest moved and the config has to be opened to read the change; the shape is a function of the text the digest holds, so every shape #987 withholds stays withheld and its rotations quiet, and it moves no row, direction, severity, expansion signal or `check` decision (#934, `tests/test_hook_command_shape.py`). `check` compares without a plugin-reference limit both sides share on an untouched source, which it cannot name and, untouched, does not route; a limit only one side carries makes its comparison incomparable. Those rows are not what routes a change: `check`, and the boundary check a manifest-backed `verify` runs, route a changed hook declaration of a plugin the project settings enable through the existing protected-surface rule, from the plugin hook reader's selection on both compared sides, and count a changed hook file such a plugin selects that the reader does not open as incomplete input; the rows beside either are unchanged (#809, `tests/test_enabled_plugin_hook_routing.py`). A partial clone that never fetched the base's objects is refused as `objects_missing`, exit `2`, never compared and never fetched; the refusal ends with the remediation sentence `verify` reports for the same reason, produced by the same function (#817, `tests/test_capability_diff_partial_clone.py`). The text of `diff`, `verify`, the PR comment and `check` reads the rows through one function, `review_changes`, and adds no row and changes no row value in any JSON projection (#795, `tests/test_host_diff_review_changes.py`): a permission rule is named with its disposition; an MCP server with the command name (never its path) or redacted URL, its package and argument digest (#819) and the env and header key names its grant already publishes, a URL printing only in the engine's sanitized scheme-and-host form and otherwise as `url not shown`, or, when none of those differ, a sentence naming what was compared and that the change is in a detail not shown, such as the command's path or another setting; a hook with each handler field that changed — its group's matcher, its command as its executable's name and digest, its timeout — before and after, a handler only one side declares, or the published handlers in a different order with a detail not shown that may also differ, and past the handler bound the same kind of sentence naming a handler past it, all read from the handlers its host-grants `0.7` grant publishes, which hold no command or argument text, and never re-derived here, and a declaration outside the documented hooks shape named as not shown rather than guessed (#819, `tests/test_hook_mcp_detail_fields.py`); those hook and MCP members display what `config_sha256` already binds, so grant equality and every inventory digest leave them out, a saved baseline holds none of them, and no row, row value, reason, digest or control answer moves; the PR comment gives the lines 1.1.0 printed their room first, the coverage block included, and prints an entry whole when the whole comment fits, otherwise cut to the widest length of at least 60 characters at which it does, or else in its shortest form (a difference cut after its name, an added or removed grant as its row), never longer than the entry 1.1.0 printed, with one line naming `verifier.json`, so no long entry hides a row, the coverage block, the change count, the review question, the reproduction or the advisory that 1.1.0 kept (#819 review, cycles 4 and 6); an allow rule the permission lattice decided another replaced (`widened` or `narrowed`), a removed and an added rule Claude Code documents as one grant in one host, source and disposition (`respelled`, #918), or the exact rule text that moved between dispositions in one host and source (`moved`), is one entry, never on the routes that redact rule arguments; and `diff` counts entries `from N rows` when one joins rows. Comparable results with entries end with one review question, naming the row count when an entry joins rows, and every result whose comparison names a base commit and a commit or working-tree head — a zero-row result and a refusal included (#812 follow-up, `tests/test_host_comparison_coverage.py`) — ends with the compared commits, the tool version and an `agents-shipgate diff --base ` reproduction, labelled `Inputs:` rather than `Compared:` where the comparison was refused, since that run compared nothing — and a refused comparison publishes no `review` object at all, so those two lines are the only place that run states its provenance, built from the `base_commit` it publishes beside the refusal; `check` and a provided diff print the question alone, and no result without a change asks a question. Every one of those facts is published beside the rows, so a machine consumer reads what a human reads (#795 slice 2, same test file): a row adds `disposition`, the `allow`/`ask`/`deny` list a permission rule is declared under and `null` for any other kind, on every route that publishes rows; and `review` in `diff --json` (capability diff `0.3`) and `host_comparison.review` in `verifier.json` (verifier `0.20`) — one object for one comparison — carry the presented changes, each naming the `row_indexes` it stands for, the `direction` the text uses (`widened`, `narrowed`, `respelled` and `moved` included, which no single row can carry), its cells, its `why` and one `expands`, plus a `summary` of `{rows, changes, widenings}` equal to `diff`'s summary line, the review question and the reproduction command. The block is refused unless its changes stand for every published row exactly once, its counters match and no joined change's two sides read alike, so the routes that redact rule arguments publish their rows alone and never a pair that reads `X → X`; `check`'s boundary result carries rows, with their dispositions, and no block. It is presentation, not a second opinion: it is the one `review_changes` projection the text prints, so the rows, their values, their count and every control answer are what they were. A comparison read back from JSON prints the changes it published, and one whose rows a caller sliced falls back to those rows. Each comparison also says what it established (#812, `tests/test_host_comparison_coverage.py`): `coverage` in `diff --json` (capability diff `0.3`) and `host_comparison.coverage` in `verifier.json` (verifier `0.20`) are the same object, printed as `What this run established` by `diff`, `verify` text and the PR comment. It is read off the grant changes, artifact changes, observed sources and blocking issues the comparator already computed: a file's rows, counting a source inside it (`#profiles.`, `#plugins.`); a file with no row and no artifact change called unchanged (`compared`, `0` rows) only when Git proves its blob identical, as the check `unchanged_limits` uses does, asked privately in one bounded batch and never published, because the artifact digest redacts `env` values and `apiKeyHelper`; a file that changed with no compared grant moving (`changed_without_grant_change`), whose artifact differs only in its digest or whose content Git shows differs while its artifact did not (never a difference a checkout line-ending conversion or a converting attribute explains, and no filter is run), never a plugin manifest or marketplace, a retargeted link or project settings while a hook's loading basis moved, worded as no compared grant changing and never as which fields changed; any other changed file with no row (`changed_without_rows`); a file Git neither proves identical nor shows differs — a provided diff, a link read, a redacted path, a working-tree file a checkout wrote with `CRLF` that Git reports unchanged — as `unchanged_not_proven`, never no change and never a change (#812 review cycle 3); the side that published a source, worded `published by` rather than `read in` for a plugin manifest or marketplace, which is published only while it declares hooks; and on a refused comparison each blocking source and its kind. Outside the bounded candidate rules below, a file no inventory observed is never an item and its absence is no claim, which the block states where it is read — one line under the heading and `read_sources_only` in the JSON — so a true list cannot be taken for the account of the change (#812 follow-up); a source already in `unchanged_limits` is not repeated; the list is capped at ten with `omitted_items`, ordered so what no row shows precedes a file's rows and, among blocking limits, by kind (`unreadable`, `parse_failed`, `unresolved_precedence`, then `unsupported`, `dynamic_source_excluded`, `remote_source_excluded`) — order, not severity, and a ranking of kinds rather than of items, since `unsupported` carries both a file this entry merely does not accept and one whose own text would not parse, so an item behind the count may still be one to repair; total down to every field an item is keyed by, the source name and then its side, limit and status — and counted in text as items not listed, ranked below those listed, and the PR comment lists only what fits in the room its entries, review question, reproduction, advisory, next action and evidence leave, at most 2000 characters, so the block never pushes out a line the comment prints without it (a row list that fills the comment by itself still truncates it, as on `1.0.0`); an instruction file's line carries no redacted-values note; sources are the inventory's redacted paths; `null` means not recorded, which is how a `0.19` verifier reads. It moves no row, reason, digest, baseline, control state or next action, and `check`'s boundary result and text carry none, so neither `check` nor a provided diff asks Git anything for it. The same list names the changed inputs this entry does not read (#821, `tests/test_unread_changed_inputs.py`): capability diff `0.4` and verifier `0.21` add a `changed_not_read` item, with the `candidate` rule that named it, for each path in the comparison's own changed-file set — the committed change, or the working tree's tracked and untracked changes — that a bounded, documented rule set recognises as plausibly agent configuration (`mcp.json` in a plugin directory, a plugin manifest's `mcpServers`, a Codex, Cursor or Copilot manifest's `hooks` and the hook files it names, a manifest or marketplace that does not parse, `.cursor/hooks.json`, host settings below the repository root, a marketplace entry's external `source`) and that no inventory published; a member is named whatever read its file, because no reader reads it. It is named from the path and, for a manifest or marketplace member, its text: nothing is fetched, run or read as a grant, so it is never a row, a widening, a `check` violation or a loading claim, and an external source is described redacted and never fetched. It ranks right after the blocking limits, inside the same cap; `read_sources_only` is `false` while one is named, and the first line says so instead; `unread_candidates` and `unread_candidates_not_examined` say whether the change set was examined and how many candidates were not — past the bound of 32, or because a file the rule needed was not read or did not parse, one count the text names both causes of. A manifest-free `verify` whose only host-relevant change is such an input, or a changed candidate it counts as not examined, publishes the comparison instead of the setup route, and `verify --preview` then names `audit --host` instead of `init --write`, in an agent-related workspace too; a `0.20` verifier reads with the search not recorded. A comparison refused only by plugin-reference limits, each bounded by its plugin directory, that no compared source depends on, is `partial` instead (#808, `tests/test_partial_host_comparison.py`); any other blocking limit it carries must be one both sides share on an unchanged source, named in `unchanged_limits` as on a comparable result. Capability diff `0.4` and verifier `0.21` publish `comparison_status: partial` with the refusal's `incomparable_reasons`, the rows, review and unchanged limits established outside those directories, and each directory (the outermost, where one holds another) as the reserved `coverage.items[].scope` on the `blocking_limit` items it bounds, and never call a changed project settings file without a row `changed_without_grant_change`, since the hooks whose loading basis it decides are not all compared; `diff`, `verify` text and the PR comment lead with `Partial comparison against …` or `Host capability comparison partial: …` and `Not compared: , …` before any entry, and a partial result with no entry is never printed as no change. Independence is read off the reader's reference graph, never off directory names: any other limit that is not unchanged, a reference leaving its plugin, a plugin at the root or holding project settings, a marketplace elsewhere declaring inline hooks for it, or a directory that does not publish as itself refuses as before. It answers no engine question and moves no control: a partial comparison is not comparable, `verify`'s control and route are the refusal's, the control envelope projects it as `incomparable` with no rows, and `check`, whose boundary result cannot name a directory, refuses its comparison and decides exactly as before. A `0.20` verifier claiming a partial comparison or a scope is refused. A plain instruction document (`AGENTS.md`, `AGENTS.override.md`, `CLAUDE.md`) both sides read directly, refused only because it is past the 256 KiB instruction bound, is withheld the same way and named as its own `scope` with `limit: unsupported`, since that profile publishes no grant and so no compared row depends on its text; a skill, command, Cursor rule, unread role, NUL byte, one-sided or linked document, or one proven unchanged (named in `unchanged_limits`) is treated as before, and a blocking limit both sides carry ends its `detail` and its line with whether Git shows its file changed in this change, identical, or neither (#973, `tests/test_oversized_instruction_document_partial.py`). A selected hook's script bytes are a comparison input of its hook grant (#702, `tests/test_hook_script_capture.py`, `tests/test_hook_script_comparison_limits.py`): a script-only edit is one `changed` row on the declaring hook, never an expansion, whose `why` names the script and loading basis and whose change carries the digests, read from the `script_inputs` the engine published; the script's own coverage line is `changed_without_rows`, which the text words as the row of the hook that runs it naming it, and a script only one side's hooks select is `compared` on that side, its selection change being the hook's row. A script the reader could not read costs that script only: a shared limit Git proves unchanged, or a script Git proves is on neither side, is an `unchanged_limits` entry of kind `unreadable`, and any other makes the comparison `partial` with a `blocking_limit` item naming the script as both `source` and `scope`, and `Not compared: the bytes of …` in the text; a working-tree difference a line-ending conversion can explain is `unchanged_not_proven`, not a row. A selected hook whose script is not resolved is a `script_not_resolved` item naming each handler and its reason, while the change could touch it, never a row, widening or limit. `check` and the boundary check of a manifest-backed `verify` route a changed selected script as a protected change of the hosts selecting it, from both compared sides' declarations, reading the base's only when the change touches a declaration (`tests/test_hook_script_routing.py`); `check` and a provided diff, which name no limit, leave out a selected script the change does not touch, from their comparison and input coverage alike, and a provided diff that touches both a script and its declaring file compares the script's bytes as the diff states them (`tests/test_hook_script_comparison_limits.py`). | +| `capability_diff` | `src/agents_shipgate/cli/diff.py`, `src/agents_shipgate/core/capability_diff_rows.py`, `src/agents_shipgate/core/host_comparison.py`, `src/agents_shipgate/report/host_comparison.py`, `src/agents_shipgate/core/unread_inputs.py`, `src/agents_shipgate/cli/verify/changed_inputs.py` | — | — | Answers no question the engine answers: it emits no verdict, no release decision and no pin. Every field is read from the drift payload the engine already produces — `risk` is the engine's severity and `expansion_signals` is the engine's word on widening — so there is no second implementation to drift. A `permission_mode` or `sandbox` row names the setting and its value as the file spells it (`enableAllProjectMcpServers: true`, `defaultMode: dontAsk`), recovered from the grant's published value and digest, and a Claude Code setting's `why` is the basis the engine's one setting table (`core/host_settings.py`) records for the value; that table also rates the grant and `check`'s violation, so a row's severity and the violation's risk give one answer (#827, `tests/test_prompt_disabling_settings.py`). `verify`/PR and `check` reuse the host comparator (#684, `tests/test_manifest_free_pr_rows.py`), and the source name each named reusable-workflow secret refers to, also non-widening, with a redacting name or target refused rather than compared, and an unreadable value neither compared nor named on this surface — only the host inventory and `audit --host` name its `job/destination`, as on `1.0.0` (#693, `tests/test_reusable_workflow_secret_mappings.py`); check retains argument redaction, except that an allow rule the engine rates as reaching a [documented arbitrary-code launcher](engineering/exec-equivalent-permissions.md) is shown in table text (`Bash(npx *)`, or a wider rule's own prefix of it, `Bash(python3 *)`) and never with a user operand, the one rating `diff`, `audit --host`, `verify` and the PR comment also carry, and its existing local-policy control (#824, `tests/test_exec_equivalent_permissions.py`). Missing comparison evidence never supplies empty comparable rows. A Claude Code permission rule row's `direction`, `expands` and `why` read the engine's one rule model (`core/claude_permission_rules.py`), the reading drift's `expansion_signals` and `check`'s violations come from, so a covered, respelled, never-consulted or carve-out rule gets one answer on every route (#918, #941, #969, #974, #938, `tests/test_claude_permission_rule_model.py`). A permission rule's cell is the text the settings reader published, never re-redacted here: a URL in it keeps its closing delimiter and trailing wildcard and withholds its path, query, fragment and userinfo, with a digest where it withholds a URL part, so two rules that publish alike stay two rows and two changes on every route (#922, `tests/test_permission_rule_url_redaction.py`). Default host mode only (`--application` is registered separately below); workflow rows compare effective writes and reusable secret recipients (#685, `tests/test_workflow_capability_diff.py`), with the privileged `pull_request_target` event stated apart from the job token scopes, a calling job's permissions printed as a ceiling whose reach the engine read from a same-repository callee's own permissions (`callee_permissions`, `callee_write_scopes` on the grant), and an inheriting call re-pinned to another reference of the same workflow a reference change rather than a new recipient, all read off the grant and `expansion_signals` the engine published (#920, #921, #924, `tests/test_actions_token_scope.py`), and each job's remote step action references, as a non-widening change (#771, `tests/test_workflow_step_action_references.py`); and each job's agent launches — a documented agent action's permission inputs, the permission flags of a `run:` that is one plain `claude -p` / `codex exec` command — and checkout refs, compared as text, as a change unless the job gains a documented widening rule, which the engine names in `expansion_signals` (`workflow_agent_widened_*`) — a rule read only from text the engine reads exactly (no shell is parsed; an argument input that is not a plain list of words is compared by a digest and read for no rule), and a gain the engine does not claim (a rule moved in from a job the launch left, one an unread step of the job rewritten as a read launch may already have met, or one the job's launch held before in an expression or an unread argument input) named in the `why` from the same engine function, never counted — with a note on a workflow row naming the untrusted-input trigger, write scopes, secrets and pull request checkout beside each agent step, read off the grant the engine published and moving no direction; an unread `run:` agent step (never compared, so never a row), an unreadable value or a setting published redacted is named only by the host inventory and `audit --host`, as for an unread secret value, an unread argument input or an unresolved launch is named there and in the `why` of a row reporting its launch, and a checkout ref holding credential-shaped text is refused as a redacting step reference is (#823, `tests/test_workflow_agent_launches.py`); every job id, step label, trigger and scope name those rows print is the label the engine published once where it built the grant, redacted, never re-derived here; `check`'s workflow evidence is derived from the raw declarations, which it still compares, and redacts job and scope names by the same rule; two distinct job ids or triggers in one workflow, or scope names in one `permissions` mapping, that publish alike are refused rather than compared, so while such a workflow exists `check` refuses on every run even when it is unchanged (#802, `tests/test_workflow_label_redaction.py`); artifact-only edits remain separate evidence. Tool-source subjects are #655. Where a partial or experimental surface is byte-identical on both sides, `diff` and `verify` compare the rest and name it in `unchanged_limits`; `check` keeps refusing, because its boundary result cannot carry a limit yet (#721). A surface the reader reaches through an in-tree link it reads through qualifies only when that link, a link with the same text at each link on the way, and the file it lands on, the same blob at the same path, are both unchanged, read from the base's Git tree entries against a commit's or, without following any link, the working tree's; any change to either is treated as before. The same proof decides which shared plugin-reference limits `check` leaves out, so behind such a link `check` compares, and publishes the rows it finds, exactly as for a limit at its own path, and a comparison `partial` only because of such a limit is `comparable` with it in `unchanged_limits` (#822, `tests/test_linked_unchanged_limits.py`). An added or changed MCP row's `why` appends a launch-source note — `launch source is mutable`, or `launch source moved from pinned … to mutable …` when both sides establish a pin — read from the `launch_source` the engine published on the grant by a bounded declaration grammar ([mcp-launch-source-notes](engineering/mcp-launch-source-notes.md)); grant equality, the inventory digests and saved baselines leave that fact out, so the note adds no row and moves no direction, `expands`, severity, expansion signal or `check` decision (#825, `tests/test_mcp_launch_source.py`). An `npx` package named with no version specifier reads instead `package spec has no exact version; launch resolution not established: npx may resolve a local project dependency or fall back to the registry/cache`, from the display-only `resolution: local_project_or_registry` the engine published beside the pin (host-grants `0.9`), as npm documents `npx` resolving such a name; no `package.json`, lockfile or cache is read, and nothing else moves (#933). A changed MCP row names the plain environment-variable names its `env_vars` list gained and lost (`env_vars names +CODEX_SECURITY_PLUGIN_ROOT`, or `in a different order`) from the display-only `env_var_names` the engine published on the grant (host-grants `0.9`), never a value; grant equality, the inventory digests and saved baselines leave it out, so it adds no row and moves no direction, `expands`, severity, expansion signal or `check` decision (#795, `tests/test_mcp_env_var_names.py`). A removed MCP row reads `the server is no longer declared in this source; whether it is still offered through a changed declaration this entry does not read is not established` instead of `an MCP tool surface is no longer offered to the agent` when the same comparison's #821 discovery names a changed, unread input that may declare MCP servers in the head (a plugin manifest's `mcpServers`, a manifest that does not parse, a plugin's `mcp.json`) in the same plugin scope and for the same host; the input is never read, matched or paired, keeps its coverage item, and no direction, `expands`, severity or `check` decision moves; `check` lists the changed files for it only when a server is removed and a provided diff states only the files it touches (#929, `tests/test_mcp_row_bounded_wording.py`). An MCP row's subject names the host the engine published its grant under, which for a `.mcp.json` is the host whose declaration selects it (#936): `codex` for a Codex plugin's, and no host for one the inventory published under `unknown`, whose `why` then says the host is not established; it restates the inventory's attribution, which `check`'s `affected_hosts` and `host_coverage` read too, and moves no direction, `expands`, severity, expansion signal or `check` decision (`tests/test_mcp_host_attribution.py`). A hook row's `why` states the grant's loading basis, read from its published `source`, `access` and `risk` by the engine's `hook_loading_basis`; only a hook the host loads for this project earns an expansion signal — one a settings layer declares, or one a plugin selects that the repository's project settings enable from an in-repository marketplace — so a declared-only hook, or one a plugin selects without that enablement, is a row and never an expansion, and a removal names no basis (#714). An added or changed Claude Code `PreToolUse` hook row whose basis is host configuration or a project-enabled plugin appends `inline allow auto-approves matched tool calls without a prompt (matcher …)` when a handler's published `inline_allow` is true — the engine's reading of a literal, unconditional allow on a broad matcher by a bounded declaration grammar ([inline-hook-allow-notes](engineering/inline-hook-allow-notes.md)), which grant equality, the inventory digests and saved baselines leave out — so the note adds no row and moves no direction, `expands`, severity, expansion signal or `check` decision (#826, `tests/test_inline_hook_allow.py`). A Claude Code tool-event hook row reads the `matcher_reach` the engine published on each handler (host-grants `0.9`): a hook every one of whose handlers is `no_tool_name` — its declared matcher, read by a bounded parser that never runs it, can match no built-in or MCP tool name, as with `Bash(git push*)` — earns no expansion signal, and its row is `declares a hook no tool call can trigger` and names the matcher, as does a row whose hook also has handlers that can run; the engine counts the handlers a tool call may run to decide a widening, so `diff`, `verify`, the PR comment, `check`'s rows and drift give one answer, and `check`'s decision does not move (#940, `tests/test_hook_matcher_reach.py`). A hook row also names a handler's exec-form `args` — the first argument shaped as a relative script path that no redaction rule rewrites, alone or after the arguments before it, and a digest of the rest, never other argument text — and the documented `type`, `async`, `asyncRewake`, `shell` and `once` settings it declares, before and after, read from the display-only `handlers` the engine published (host-grants `0.9`), which grant equality, the inventory digests and saved baselines leave out, so the field difference reaches the text and `review.changes[].change` and moves no row, direction, severity, expansion signal, loading basis or `check` decision, and a change confined to a field still not published, such as `if` or `statusMessage`, still says it is not shown (#972, #971, `tests/test_hook_args_and_settings.py`). A hook row also describes a changed inline command by the structure the engine published on its display-only `command.shape` (host-grants `0.9`) — the plain-token programs at its command positions, counts of commands, pipes, substitutions, control-flow keywords and quoted strings, its file redirects and a script path, never an argument, quoted string, URL or absolute path — or, when the engine published `shape_limit` instead, says the command is not described, the digest moved and the config has to be opened to read the change; the shape is a function of the text the digest holds, so every shape #987 withholds stays withheld and its rotations quiet, and it moves no row, direction, severity, expansion signal or `check` decision (#934, `tests/test_hook_command_shape.py`). `check` compares without a plugin-reference limit both sides share on an untouched source, which it cannot name and, untouched, does not route; a limit only one side carries makes its comparison incomparable. Those rows are not what routes a change: `check`, and the boundary check a manifest-backed `verify` runs, route a changed hook declaration of a plugin the project settings enable through the existing protected-surface rule, from the plugin hook reader's selection on both compared sides, and count a changed hook file such a plugin selects that the reader does not open as incomplete input; the rows beside either are unchanged (#809, `tests/test_enabled_plugin_hook_routing.py`). A partial clone that never fetched the base's objects is refused as `objects_missing`, exit `2`, never compared and never fetched; the refusal ends with the remediation sentence `verify` reports for the same reason, produced by the same function (#817, `tests/test_capability_diff_partial_clone.py`). The text of `diff`, `verify`, the PR comment and `check` reads the rows through one function, `review_changes`, and adds no row and changes no row value in any JSON projection (#795, `tests/test_host_diff_review_changes.py`): a permission rule is named with its disposition; an MCP server with the command name (never its path) or redacted URL, its package and argument digest (#819) and the env and header key names its grant already publishes, a URL printing only in the engine's sanitized scheme-and-host form and otherwise as `url not shown`, or, when none of those differ, a sentence naming what was compared and that the change is in a detail not shown, such as the command's path or another setting; a hook with each handler field that changed — its group's matcher, its command as its executable's name and digest, its timeout — before and after, a handler only one side declares, or the published handlers in a different order with a detail not shown that may also differ, and past the handler bound the same kind of sentence naming a handler past it, all read from the handlers its host-grants `0.7` grant publishes, which hold no command or argument text, and never re-derived here, and a declaration outside the documented hooks shape named as not shown rather than guessed (#819, `tests/test_hook_mcp_detail_fields.py`); those hook and MCP members display what `config_sha256` already binds, so grant equality and every inventory digest leave them out, a saved baseline holds none of them, and no row, row value, reason, digest or control answer moves; the PR comment gives the lines 1.1.0 printed their room first, the coverage block included, and prints an entry whole when the whole comment fits, otherwise cut to the widest length of at least 60 characters at which it does, or else in its shortest form (a difference cut after its name, an added or removed grant as its row), never longer than the entry 1.1.0 printed, with one line naming `verifier.json`, so no long entry hides a row, the coverage block, the change count, the review question, the reproduction or the advisory that 1.1.0 kept (#819 review, cycles 4 and 6); an allow rule the permission lattice decided another replaced (`widened` or `narrowed`), a removed and an added rule Claude Code documents as one grant in one host, source and disposition (`respelled`, #918), or the exact rule text that moved between dispositions in one host and source (`moved`), is one entry, never on the routes that redact rule arguments; and `diff` counts entries `from N rows` when one joins rows. Comparable results with entries end with one review question, naming the row count when an entry joins rows, and every result whose comparison names a base commit and a commit or working-tree head — a zero-row result and a refusal included (#812 follow-up, `tests/test_host_comparison_coverage.py`) — ends with the compared commits, the tool version and an `agents-shipgate diff --base ` reproduction, labelled `Inputs:` rather than `Compared:` where the comparison was refused, since that run compared nothing — and a refused comparison publishes no `review` object at all, so those two lines are the only place that run states its provenance, built from the `base_commit` it publishes beside the refusal; `check` and a provided diff print the question alone, and no result without a change asks a question. Every one of those facts is published beside the rows, so a machine consumer reads what a human reads (#795 slice 2, same test file): a row adds `disposition`, the `allow`/`ask`/`deny` list a permission rule is declared under and `null` for any other kind, on every route that publishes rows; and `review` in `diff --json` (capability diff `0.3`) and `host_comparison.review` in `verifier.json` (verifier `0.20`) — one object for one comparison — carry the presented changes, each naming the `row_indexes` it stands for, the `direction` the text uses (`widened`, `narrowed`, `respelled` and `moved` included, which no single row can carry), its cells, its `why` and one `expands`, plus a `summary` of `{rows, changes, widenings}` equal to `diff`'s summary line, the review question and the reproduction command. The block is refused unless its changes stand for every published row exactly once, its counters match and no joined change's two sides read alike, so the routes that redact rule arguments publish their rows alone and never a pair that reads `X → X`; `check`'s boundary result carries rows, with their dispositions, and no block. It is presentation, not a second opinion: it is the one `review_changes` projection the text prints, so the rows, their values, their count and every control answer are what they were. A comparison read back from JSON prints the changes it published, and one whose rows a caller sliced falls back to those rows. Each comparison also says what it established (#812, `tests/test_host_comparison_coverage.py`): `coverage` in `diff --json` (capability diff `0.3`) and `host_comparison.coverage` in `verifier.json` (verifier `0.20`) are the same object, printed as `What this run established` by `diff`, `verify` text and the PR comment. It is read off the grant changes, artifact changes, observed sources and blocking issues the comparator already computed: a file's rows, counting a source inside it (`#profiles.`, `#plugins.`); a file with no row and no artifact change called unchanged (`compared`, `0` rows) only when Git proves its blob identical, as the check `unchanged_limits` uses does, asked privately in one bounded batch and never published, because the artifact digest redacts `env` values and `apiKeyHelper`; a file that changed with no compared grant moving (`changed_without_grant_change`), whose artifact differs only in its digest or whose content Git shows differs while its artifact did not (never a difference a checkout line-ending conversion or a converting attribute explains, and no filter is run), never a plugin manifest or marketplace, a retargeted link or project settings while a hook's loading basis moved, worded as no compared grant changing and never as which fields changed; any other changed file with no row (`changed_without_rows`); a file Git neither proves identical nor shows differs — a provided diff, a link read, a redacted path, a working-tree file a checkout wrote with `CRLF` that Git reports unchanged — as `unchanged_not_proven`, never no change and never a change (#812 review cycle 3); the side that published a source, worded `published by` rather than `read in` for a plugin manifest or marketplace, which is published only while it declares hooks; and on a refused comparison each blocking source and its kind. Outside the bounded candidate rules below, a file no inventory observed is never an item and its absence is no claim, which the block states where it is read — one line under the heading and `read_sources_only` in the JSON — so a true list cannot be taken for the account of the change (#812 follow-up); a source already in `unchanged_limits` is not repeated; the list is capped at ten with `omitted_items`, ordered so what no row shows precedes a file's rows and, among blocking limits, by kind (`unreadable`, `parse_failed`, `unresolved_precedence`, then `unsupported`, `dynamic_source_excluded`, `remote_source_excluded`) — order, not severity, and a ranking of kinds rather than of items, since `unsupported` carries both a file this entry merely does not accept and one whose own text would not parse, so an item behind the count may still be one to repair; total down to every field an item is keyed by, the source name and then its side, limit and status — and counted in text as items not listed, ranked below those listed, and the PR comment lists only what fits in the room its entries, review question, reproduction, advisory, next action and evidence leave, at most 2000 characters, so the block never pushes out a line the comment prints without it (a row list that fills the comment by itself still truncates it, as on `1.0.0`); an instruction file's line carries no redacted-values note; sources are the inventory's redacted paths; `null` means not recorded, which is how a `0.19` verifier reads. It moves no row, reason, digest, baseline, control state or next action, and `check`'s boundary result and text carry none, so neither `check` nor a provided diff asks Git anything for it. The same list names the changed inputs this entry does not read (#821, `tests/test_unread_changed_inputs.py`): capability diff `0.4` and verifier `0.21` add a `changed_not_read` item, with the `candidate` rule that named it, for each path in the comparison's own changed-file set — the committed change, or the working tree's tracked and untracked changes — that a bounded, documented rule set recognises as plausibly agent configuration (`mcp.json` in a plugin directory, a plugin manifest's `mcpServers`, a Codex, Cursor or Copilot manifest's `hooks` and the hook files it names, a manifest or marketplace that does not parse, `.cursor/hooks.json`, host settings below the repository root, a marketplace entry's external `source`) and that no inventory published; a member is named whatever read its file, because no reader reads it. It is named from the path and, for a manifest or marketplace member, its text: nothing is fetched, run or read as a grant, so it is never a row, a widening, a `check` violation or a loading claim, and an external source is described redacted and never fetched. It ranks right after the blocking limits, inside the same cap; `read_sources_only` is `false` while one is named, and the first line says so instead; `unread_candidates` and `unread_candidates_not_examined` say whether the change set was examined and how many candidates were not — past the bound of 32, or because a file the rule needed was not read or did not parse, one count the text names both causes of. A manifest-free `verify` whose only host-relevant change is such an input, or a changed candidate it counts as not examined, publishes the comparison instead of the setup route, and `verify --preview` then names `audit --host` instead of `init --write`, in an agent-related workspace too; a `0.20` verifier reads with the search not recorded. A comparison refused only by plugin-reference limits, each bounded by its plugin directory, that no compared source depends on, is `partial` instead (#808, `tests/test_partial_host_comparison.py`); any other blocking limit it carries must be one both sides share on an unchanged source, named in `unchanged_limits` as on a comparable result. Capability diff `0.4` and verifier `0.21` publish `comparison_status: partial` with the refusal's `incomparable_reasons`, the rows, review and unchanged limits established outside those directories, and each directory (the outermost, where one holds another) as the reserved `coverage.items[].scope` on the `blocking_limit` items it bounds, and never call a changed project settings file without a row `changed_without_grant_change`, since the hooks whose loading basis it decides are not all compared; `diff`, `verify` text and the PR comment lead with `Partial comparison against …` or `Host capability comparison partial: …` and `Not compared: , …` before any entry, and a partial result with no entry is never printed as no change. Independence is read off the reader's reference graph, never off directory names: any other limit that is not unchanged, a reference leaving its plugin, a plugin at the root or holding project settings, a marketplace elsewhere declaring inline hooks for it, or a directory that does not publish as itself refuses as before. It answers no engine question and moves no control: a partial comparison is not comparable, `verify`'s control and route are the refusal's, the control envelope projects it as `incomparable` with no rows, and `check`, whose boundary result cannot name a directory, refuses its comparison and decides exactly as before. A `0.20` verifier claiming a partial comparison or a scope is refused. A plain instruction document (`AGENTS.md`, `AGENTS.override.md`, `CLAUDE.md`) both sides read directly, refused only because it is past the 256 KiB instruction bound, is withheld the same way and named as its own `scope` with `limit: unsupported`, since that profile publishes no grant and so no compared row depends on its text; a skill, command, Cursor rule, unread role, NUL byte, one-sided or linked document, or one proven unchanged (named in `unchanged_limits`) is treated as before, and a blocking limit both sides carry ends its `detail` and its line with whether Git shows its file changed in this change, identical, or neither (#973, `tests/test_oversized_instruction_document_partial.py`). A selected hook's script bytes are a comparison input of its hook grant (#702, `tests/test_hook_script_capture.py`, `tests/test_hook_script_comparison_limits.py`): a script-only edit is one `changed` row on the declaring hook, never an expansion, whose `why` names the script and loading basis and whose change carries the digests, read from the `script_inputs` the engine published; the script's own coverage line is `changed_without_rows`, which the text words as the row of the hook that runs it naming it, and a script only one side's hooks select is `compared` on that side, its selection change being the hook's row. A script the reader could not read costs that script only: a shared limit Git proves unchanged, or a script Git proves is on neither side, is an `unchanged_limits` entry of kind `unreadable`, and any other makes the comparison `partial` with a `blocking_limit` item naming the script as both `source` and `scope`, and `Not compared: the bytes of …` in the text; a working-tree difference a line-ending conversion can explain is `unchanged_not_proven`, not a row. A selected hook whose script is not resolved is a `script_not_resolved` item naming each handler and its reason, while the change could touch it, never a row, widening or limit. `check` and the boundary check of a manifest-backed `verify` route a changed selected script as a protected change of the hosts selecting it, from both compared sides' declarations, reading the base's only when the change touches a declaration (`tests/test_hook_script_routing.py`); `check` and a provided diff, which name no limit, leave out a selected script the change does not touch, from their comparison and input coverage alike, and a provided diff that touches both a script and its declaring file compares the script's bytes as the diff states them (`tests/test_hook_script_comparison_limits.py`). A Claude Code setting the host runs as a command (`statusLine`, `subagentStatusLine`, `fileSuggestion`, `apiKeyHelper`, `otelHeadersHelper`, `awsAuthRefresh`, `awsCredentialExport`) or an `env` entry that redirects requests, changes TLS trust or loads code is a row read off the `command_setting` or `env` grant the engine published (host-grants `0.9`), its command shown as a hook's is and an `env` value never shown; a comparable result with no row in which a settings, MCP or hook file changed leads with `Changed, not compared: ()`, read off its coverage items and the `detail` naming the keys no reader compares, instead of `No static host-grant changes detected`; no `check` decision moves (#1027, `tests/test_claude_command_settings.py`). | | `application_diff` | `src/agents_shipgate/cli/application_diff.py`, `src/agents_shipgate/cli/application_scope.py`, `src/agents_shipgate/cli/application_summary.py`, `src/agents_shipgate/inputs/tool_reach.py` | — | — | Advisory SDK/ADK source-wiring comparison through `diff --application`. Without `--scope` the scope is derived from the change: the outermost package holding each changed Python file and the agent-building SDK/ADK files (discovery's own signals) that import it or that it imports within six hops, with what they import. Each independent application is its own comparison and never the root by default; agents only the root would join are named as `outside` and make the answer `partial`. A whole application directory moved is one relocation. A change no agent reaches is an explicit `not_established` answer, and a bound reached is named in `scope_selection` and makes the answer `partial` (#875, `tests/test_application_scope.py`). Reuses framework observations and the binding graph; its comparator answers no release or merge verdict, activation verdict, executable pin, or declared authority question. Unlike host mode it computes per-agent source differences, not a projection of host drift. Scoped gaps and `not_established` candidates bound the answer; no deployment-root reachability is asserted. An agent the other side's file still names through a construction no reader supports is a gap there, never a removal or addition, and SDK identity follows the import, so LiveKit's `Agent`/`function_tool` are not read as the SDK's. `tests/test_application_diff.py`, `tests/test_application_diff_review.py` and `tests/test_application_diff_identity.py` prove the advisory boundary, isolation, uncertainty and evidence identity. Every scope, the root included, is materialized by the scoped verified materializer, so a link is recreated rather than refused and never read through; every link under the scope, a dangling one included, is censused and gapped only where it can hide application source (a `*.py` link not aliasing an input the scope reads, a directory link holding Python outside the scope, or an unresolved link where the other side reads source); a submodule is never read, named as a limit when its gitlink commit is unchanged and a coverage gap over its path (the whole scope at the scope itself) otherwise; the host-configuration census adds no application gap (`tests/test_application_diff_reach.py`). A tool an agent binds from another module inside the selected scope is followed by the SDK/ADK readers to its definition, never imported or run, and each module read is published with its digest as `import_path` evidence outside the compared meaning; an import they cannot follow stays a named gap scoped to its agent (#864, `tests/test_imported_tool_bindings.py`). An unobserved agent is not no change (#876): every OpenAI Agents SDK construction in a file the scope reads is an observed agent or a named limit — `return Agent(...)`, `self.agent = Agent(...)`, an inline agent, `Agent[Context](...)` and a positional name are read under their literal `name`; `**` or extra positional arguments, a capability-passing copy, a change to an agent's tools after construction, one identity constructed twice with different tools, a construction without a literal name, and an agent built from an SDK `Agent` subclass or from a class deriving from a Google ADK agent class are limits — so `compared` holds no unaccounted construction site. Test code, by discovery's test-path convention relative to the scope, establishes nothing and is listed per side in the additive `excluded_tests` field, a list of the comparison's own unread input paths that restates no engine answer and adds no claim; a tool name one application file defines twice is a gap on that name, never a refusal (`tests/test_application_diff_unobserved.py`). Each side of a row also carries `reach` (#872). It holds the outbound HTTP calls read statically from the tool's own code and its same-scope helpers, up to three calls deep. For each call it records the method, the URL template and literal request fields, which model-supplied parameters flow where, and the environment variables sent as credentials, by name, never a value. Every call it cannot follow is a named limit. `effect_evidence` is the engine's own `assess_tool_semantics` over that tool, with the reach as one more structural source, `source_http_call`, so it is not a second classifier. `read` is claimed only when every call was followed and every outbound call reads. `reach.effects` (#913) names what the tool's code reaches beyond HTTP through a recognised database, process, file, cloud SDK or messaging library (`src/agents_shipgate/inputs/tool_effects.py`), by import identity and method, never a spelling: a SQL statement, a command's arguments and a withheld path are only digested, and a method outside the tables is a limit. Such an effect is one more structural source of the same assessment, `source_library_call`, and `read` still needs everything reached to read, so it adds no claim either (`tests/test_tool_reach_effects.py`). Both are evidence outside the compared meaning, so they move no row or status. For a Google ADK name constructed more than once, `binding_location` names a construction that lists the tool, and `construction_sites` lists every one (`tests/test_application_diff_tool_reach.py`). A tools, handoffs or sub-agents list built by an expression — a spread, `+`, a conditional, `or`, a filter, another module's list — is read member by member through one resolver both readers share, and each part it cannot read is named, with its location, on the agent it belongs to, which stays incomplete. A member held only under a condition carries `bound_when`, the condition's source text, never evaluated; it restates no engine answer, and a change to it alone is a `changed` row whose direction is not established (#909, `tests/test_list_expressions.py`). A tool bound as an object — an MCP server or toolset, an agent exposed as a tool, a hosted or built-in tool recognised by its import, never its spelling — is a binding whose side carries `object`, what it is (transport, URL host or program file name, credential names, filter; the wrapped agent; the tool name), and `object_evidence`; a URL's path or query, a header value and a command's arguments are only digested, never printed. Both are facts about the source, read for `diff --application` only, so `scan` reads what it did and neither restates an engine answer (#910, `tests/test_object_bound_tools.py`). The comparison opens with an additive `summary` block and the text built from it (#914): one finding per changed agent, the first thing not read, one entry per cause shared by `not_established` rows, and a question specific to what changed. It is a reading of the rows, derived from the sanitized rows and naming the rows it summarizes by index: it moves no row, status, direction, gap, scope or exit code, states nothing a row does not, and is excluded from the benchmark's `answer_id`, so it restates no engine answer and adds no claim. A finding is `partial` when any of its tools has an unread binding or reach, and says so with the first place reading stopped; `comparison_status` is unchanged and still speaks of bindings only (`tests/test_application_summary.py`). | | `zero_install_detector` | `tools/shipgate-detect.py` | `agent_project_verdict` | `test_detector_verdict_matches_cli` | Emits no `diagnostics[]` and no `next_actions[]`; evidence strings and framework scores are simplified.

Since `1.1.0`, a widening entry is marked `⚠`, a permission rule names its disposition, a replaced or moved rule is one `widened`, `narrowed` or `moved` entry, an MCP server names its published command name (not its path) or redacted URL and key names, and the entries end with `Review question: Does the team intend …?`, a `Compared:` line naming the base and head commits and the version, and a `Reproduce:` line with the `agents-shipgate diff --base ` to run after checking out the head. Both lines also end a comment with no change. A comment whose comparison was unavailable ends with the same two lines, the first labelled `Inputs:` rather than `Compared:`, since that run compared nothing — but only where that run named a base commit: `shallow_history` and an unfetched base name none, so those comments carry neither line, as they carry no block. Neither asks a question. On `pull_request` that head is the commit the Action compared, `github.sha`: GitHub's merge commit for the PR, not the branch tip. No branch holds it, so fetch it first with `git fetch origin refs/pull//merge`, which serves it only until a later push to the PR or its base branch replaces it. - **No change** — `Repository-declared host capability changes:`, then `No static host-grant changes detected in the covered comparison. No verdict is implied.` -- Either of those can add **Not compared** — `Not compared: unchanged in this change and not read, so no claim is made about them:` and the sources it skipped, such as an unparseable `.cursor/mcp.json` the PR did not touch. Nothing is claimed about those. +- **Changed, not compared** — `Repository-declared host capability changes:`, then `Changed, not compared: (). No host-grant row describes this change. No verdict is implied.` when a settings, MCP or hook file changed with no row, such as in a key this entry does not compare (#1027, after `1.2.0`). It is not a no-change answer. +- Any of those can add **Not compared** — `Not compared: unchanged in this change and not read, so no claim is made about them:` and the sources it skipped, such as an unparseable `.cursor/mcp.json` the PR did not touch. Nothing is claimed about those. - **Cannot compare** — `Host capability comparison unavailable:` with the reason, such as `head_inventory_incomplete` for a configuration file the PR leaves unreadable, or `shallow_history` for a clone without the base branch's history. That is an input limit, not a finding and not a pass. - Since `1.1.0`, an answer from a comparison that read both sides — every one above but `shallow_history` — is followed by **What this run established**: the sources compared and how many rows each gave, a source that changed with no compared grant changing (so an `env` or `apiKeyHelper` edit to `.claude/settings.json`, key or value, no longer looks like no change; a source is listed as unchanged only when its bytes are proven identical), any other changed source no row is attributed to, such as a plugin manifest's `hooks` reference, a source only the base or the head read or published, such as a deleted file or an untracked `.claude/settings.local.json`, and for an unavailable comparison each source that left an inventory incomplete, with its kind. It lists sources the comparison already read or tried to read and, after `1.1.0` (not in the pinned release yet), a changed input a bounded candidate list names that this entry does not read — a plugin's `mcp.json`, `.cursor/hooks.json`, a nested `.claude/settings.json`, an external marketplace source — as `added`, `removed` or `changed, not read by this entry`, never as a row (#821). Its first line says which, so it is never read as the whole account of the change; any other changed file this entry does not read is absent from it. Blocking limits come first, most actionable kind first, so a cap never hides an unreadable source behind routine ones, and what it leaves out is counted as ranking below what it lists. In the comment it lists only what fits in the room the entries and the lines after it leave, at most 2000 characters, and counts the rest, so it never pushes those lines out. diff --git a/src/agents_shipgate/cli/diff.py b/src/agents_shipgate/cli/diff.py index 74a7a8239..900adb2b7 100644 --- a/src/agents_shipgate/cli/diff.py +++ b/src/agents_shipgate/cli/diff.py @@ -448,7 +448,14 @@ def run_capability_diff( typer.echo("") if not rows: if not partial: - typer.echo("No static host-grant changes detected.
