feat: what this install knows (v1.56.0) - #185

Conversation
Phase-0 artifacts for the client-surface-parity wave: design, plan, variant audit trail and the consultant prompt and output. Every card's premise was verified against live source before the brainstorm. Three hold (the missing `--version`, the instruction block that never consults the capability window, the linked-project readers no MCP tool reaches). One is largely refuted: `o2b install --check` already aggregates per-adapter verify results across every registered target, with deadline-bounded probes and unverified named rather than assumed healthy - the residue is that the aggregate is CLI-only. One is refuted outright: release awareness has no producer for the cache it reads from, and the data ownership statement promises the operator there is no update check, so it is recorded as a refusal rather than built.

`package.json` `version` is the repository's single source of truth, and
inside `src/` three modules read it independently: `CLI_VERSION` in the
continuity export, `SERVER_VERSION` in the MCP handshake, and the
stamped header of the bundled opencode plugin. Three copies of one fact
cannot be seen to disagree, because nothing named them as copies.
`src/core/version.ts` now holds the only manifest import in the tree and
exports `OPEN_SECOND_BRAIN_VERSION`; the three readers point at it.
`tests/core/version.test.ts` carries the census that keeps the import
from spreading back out - an equality over the modules that hold it, not
a floor, with a positive control so a scanner that stops matching fails
rather than reports clean.
Defect fixed in passing: `opencode-plugin-asset.ts` imported the
manifest without the `with { type: "json" }` import attribute the other
two sites carried, so the same import was written two ways. The
attribute now appears once, on the one import that remains.

`o2b version` prints the installed version and exits 0; `--json` renders
`{"version":"…"}` for a caller that parses; the root `--version` flag is
a synonym routed to the same renderer rather than a second line that
could drift from it. An argument the verb cannot honour - `o2b version
latest` - is a usage error, because nothing in this tree learns what any
other version is and printing the local one would answer a question
nobody asked.
The MCP handshake has carried `serverInfo.version` since the server
existed. This closes the CLI half, off the same constant.
The flag is declared in `command-manifest.ts` rather than only matched
in `main.ts`: the completion scripts and `o2b help --json` are built
from that manifest, and a flag it never heard of is a flag no shell
offers. `main.ts` matches on the token spelled from that declaration, so
the dispatcher and the completions cannot disagree about the name.
`version` joins `COMMANDS_WITH_INTERNAL_JSON` so its payload is the
whole of stdout, not a wrapped envelope.

… report `initialize.instructions` is the first text every agent reads, and it was one frozen string per scope. This server already evaluates the runtime capability window in its constructor and knows, per tool, whether it is available or withheld and why - so a host that disables `brain_note` still received a paragraph telling the agent to call it. The agent calls, reads the refusal, and learns that the first thing it was told was wrong. Appending an "except these" block beneath the same prose would not fix that: an instruction and its retraction in one document leave the reader deciding which half is true. So the guidance is REMOVED, and the removal is named with the reason the evaluator already produced - no second vocabulary. `instruction-segments.ts` holds the three bodies as ordered paragraphs of tool-tagged segments. A segment renders when every tool it names is available; the separator of the preceding rendered segment joins the survivors, so a dropped clause takes its punctuation with it. A paragraph whose every tool-bearing segment dropped renders nothing at all, its lead-in included: "Five tools live here" is a claim that stops being true the moment one of them is withheld. The withheld block lists the intersection of the report's withheld entries with the names this scope's segments declare, not the whole withheld set - a `max_tools` window withholds over a hundred tools and pasting that into the handshake costs more than the removed guidance did. It points at `second_brain_capabilities`, which is never itself withheld, for the complete report. `capabilities` is a required parameter, not an optional one: defaulting to "assume everything is available" is the wrong answer this change exists to remove, and at the call site it would be indistinguishable from a runtime that really has everything. Byte-identity is pinned. `tests/fixtures/instruction-bodies/*.txt` were captured from the strings this replaces, and the fully-available render of each scope is compared against them, so a reshaping cannot become a rewrite unnoticed. A segment naming a tool its scope does not register fails the orphan census in the same file. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
`linkedProjectsStatus` already reports every registered project link
with its four-value pointer state and whether the vault it names still
exists. It had one consumer, `o2b brain project status`, and nothing
under src/mcp touched it: an agent on the MCP surface could not ask what
this install is wired into. `second_brain_wiring` with `view: "projects"`
is that seam. No new health model - the reader is unchanged.
`view` is required with no aggregate member, matching `brain_brief`,
`brain_analytics` and `schema_inspect`: every payload stays bounded, and
an absent or unknown view is an INVALID_PARAMS refusal naming the
accepted members through the shared `dispatchByView`.
Paths follow the contract that already governs them rather than a second
one. The registry is keyed on absolute host paths and an MCP response
lands in model context, so `vaultPathField`'s policy is generalised to
`hostPathReference(path, source)` - `vaultStoreReference` never required
the path to be the vault - and both sides of a link render through it.
A config that cannot be read renders `{ error }`, never the raw path the
reference exists to hide. A registry damaged by hand degrades to the
entries it can read, the tolerance `listLinkedProjects` already has.
Three censuses moved with the surface and each says why in place: the
preview-budget exemption row (bounded by construction on both sides),
the vault_path emission count 44 to 45, and the probe population 100 to
101 entries and 229 to 230 recipes, with the sentence in
docs/architecture.md that quotes them.

`o2b install --check` iterates every registered adapter, calls verify(), and renders a table or JSON with an exit code separating drift from unreachable. All of it was CLI-only: an agent on the MCP surface could not ask whether the hosts this install wrote registrations into can still be reached. `second_brain_wiring` with `view: "hosts"` is that seam - the same registry, the same verify() call, the same InstallEnv. The env builder moved from the install verb into `src/core/install/env.ts`, which is what makes "the same" literal rather than a claim: two builders would be two answers to "which machine is being verified", the split that constructor's own docblock was written to close. The CLI verb keeps its argument resolution and delegates the construction. An unresolved vault is refused by name with the sentence runCheck gives, from the one constant both surfaces now read. verify() reads the per-vault sidecar manifest, so an unset vault otherwise reports ten runtimes as not-installed off a bogus path - a wrong answer wearing the authority of a completed check. The tool description states that the view may ask host CLIs and that each wait is bounded, because a diagnostic that can take twenty seconds and does not say so is a surprise. Test note stated rather than implied: `os.homedir()` in this runtime does not follow a later `process.env.HOME`, so an in-process test cannot redirect the home the view resolves. The named-probe-skip case therefore builds the InstallEnv by hand, as the adapter suites do, and asserts the view's own mapping over the real verify() answer; the deep-equality test is what ties that mapping to the env the view builds. The out-of-vault ownership exclusion moved with the homedir() call it excuses, and the vault_path emission census reads 46 for the second view. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
…tructions `docs/cli-reference.md` gains `o2b version` in the Core list and a section covering the `--json` payload, the root `--version` synonym and why a positional argument is a usage error. `docs/mcp.md` gains a `second_brain_wiring` row and an "Installation wiring" section stating both views, the field meanings, the `expose_host_paths` path policy, the named refusal on an unresolved vault, and the probe cost - two targets declare a host probe, each wait bounded, and a probe that could not run renders its reason instead of an assumed ok. A second subsection states that the handshake instructions now follow the capability window, that a runtime withholding nothing renders byte-identical text, and why the withheld block lists the tools this text would have instructed rather than the whole withheld set. `README.md` gains one paragraph under "What you get". Defect fixed in passing: docs/mcp.md said the full server advertises 111 tools. It advertised 114 before this branch and 115 after; the count was last true at v1.51.0, which is where the sentence one section down still correctly reports it as a fact about that release.

The CHANGELOG entry for the wave that made this install able to answer what it is and what it is wired into: `o2b version` with its root synonym, `second_brain_wiring` with its projects and hosts views, and handshake instructions rendered from the live capability report. The Notes record the one card in scope that was refused rather than built. Release awareness has no producer for the cached update state it reads from, filling that cache needs a network check, and `src/core/install/ownership.ts:794` renders to the operator that this tool has no update check. Both honest alternatives amend an operator-facing promise about network behaviour, which is an operator policy decision and is recorded for the operator to take. Version bumped in `package.json` and propagated by `scripts/sync-version.ts`, inside the feature pull request per CLAUDE.md, because `main` is protected and a bump left for after the merge leaves the manifest and the CHANGELOG heading disagreeing.

…k three censuses The full run caught four things the targeted runs did not. The tool description was 315 characters against the registry's 300-char cap. The cap exists because the serialised registry is paid by every MCP client on every request, and `registry-guard.ts` states where long-form guidance goes instead: the path policy and the per-view field tables are now only in docs/mcp.md, where this branch already wrote them. Three surface censuses count the advertised table and were still at 114: the tools/list length in `mcp.test.ts` and `removed-tools.test.ts`, and the sorted name list in `mcp.test.ts`. Each carries the running tally as a comment, so each gains its line naming the tool and the cards behind it rather than a silently edited number. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
`vault_path` was reduced to an opaque `vault://<hex>` and, in the same payload, `details` handed a model the absolute path of every host config file that had drifted - `/home/<operator>/.grok/hooks/...`, composed by `verify()` out of `InstallEnv.home`. The module docblock claimed every reference went through the path producer; that was true of the fields and false of the prose. `hostPathReference` cannot render those sentences: a store reference keys the VAULT, and a hash of a third party's config file names nothing the reader can act on. So `foldHostHome` folds the one home prefix this run resolved, leaving the file identifiable and the account name behind. One exact substitution of a string the view supplied, never a search for path-shaped text; it fails closed on an unreadable config, and `expose_host_paths` un-folds it exactly as it un-hashes `vault_path`. `hostPathReference` also stops asking for a `VaultPathSource` whose `vault` it never read. The census in tests/core/architecture keys on the field NAME `vault_path` and can see neither this prose nor `project_ref`, so the assertion that guards them is over the serialised payload of both views, and the census docblock now says where its reach ends.

The withheld block closes by saying where the complete availability
report is. On the writer scope that sentence named a tool the server
answers `unknown tool: second_brain_capabilities` for: no capability
WINDOW withholds the diagnostic, but `buildToolTable("writer")` is the
five always-loaded tools and never registered it in the first place.
An agent reading its handshake, following the one pointer it was given
and getting -32601 back is exactly the defect this module was written to
remove - reintroduced by the sentence that explains the removal. The
pointer is now emitted only where the report says the tool is available;
elsewhere the block ends with the names, which is an omission rather
than a wrong instruction.
Two rules the suite stated in prose and never asserted are asserted now,
both verified by removing the rule and watching the test fail: the
pointer guard, and the paragraph-drop rule that keeps a lead-in from
surviving the clauses it leads into.

A lead-in was welded to the first tool-bearing clause, so withholding that one tool took the heading with it. A host disabling brain_feedback got a memory contract opening "brain_apply_evidence right after producing a durable artifact..." - no heading, no governing verb, a sentence starting in the middle. Disabling brain_brief left the view list as a bare "brain_analytics (view: ...), schema_inspect (view: ...)." with nothing saying what the list is. The lead-in is now a segment of its own, which is what the model always described. And because unconditional text is a lead-in by DEFAULT - it goes when its items go, or a heading outlives its list - the one sentence that is not a lead-in says so: `standsAlone` keeps the catalog's "every other tool stays callable via tools/call" when the enumeration beside it stops being true. Without it, a withheld writer left the reader meeting "Second pass:" with no first pass described anywhere. The fully-available render is unchanged, byte for byte, in every scope: the three fixtures pin it, and the degraded seams are now pinned as exact text too rather than probed with toContain, which cannot see a doubled separator or a stranded one. `PARAGRAPH_BREAK` was declared in both modules that join this document's blocks; it is declared once and imported now.

Three places where one question had two implementations that could disagree, and in two of them they already did. The root `--version` flag was handled in an arm of its own, above the dispatcher. That put it outside the `CliError` handler, so `o2b version latest` printed a usage error and exited 2 while `o2b --version latest` printed a stack trace with source context and exited 1 - the divergence the synonym exists to prevent, visible only to whoever typed the wrong one. The flag is now rewritten to the verb and goes through the one dispatcher; the verb name is read off the flag declaration, because a synonym is only a synonym while the two words agree. `second_brain_wiring view=projects` answered the empty list when the server carried no config path, while `view=hosts` in the same tool defaulted to the machine config and the CLI verb this view mirrors has always defaulted. On a box with a full registry that was "nothing is linked", which is the wrong answer rather than a missing one. `o2b aider` kept a third `InstallEnv` constructor, byte-equivalent to the one this branch extracted except that it never stamped `OPEN_SECOND_BRAIN_CONFIG` - so `o2b aider --config` handed the adapters an env whose settings resolver fell back to the machine default, the exact split `core/install/env.ts` was extracted to close. `renderScopeBody` now refuses a capability report built for another scope by name. Both arguments carry the scope, and a mismatch rendered an empty body explained by reasons untrue of that server. The handshake is also driven end to end for the first time: every prior test built its own report and called `buildInstructions`, so dropping the window on the way there compiled and failed nothing.

The release notes say this change fixes a stale tool count in docs/mcp.md. Two more were stale in the same file, and one of them this branch made staler by adding a tool: the `catalog` gap, given as "a hundred and three apart", is 108. A figure that goes wrong on the next tool added is the wrong thing to write down, so it is restated as the relation it always was - the catalog advertises seven whatever the tool table holds - in the doc and in the `advertised_tool_count` docblock the doc mirrors. The full surface, given as 49 in the `.mcp.json` section and as 115 nine hundred lines above, is now stated once and pointed at. The wiring section claimed the projects view "degrades to the entries it can still read" from a damaged registry. It does not: the registry is parsed as a whole, so a damaged file reads as no links, which is what the CLI verb answers too. Documented as what happens, with the reason the two surfaces agree. Also documented: the `vault_path` and `view` members every payload carries, the `-32602` a `hosts` read with no resolved vault is refused with, that a server with no config path reads the machine default, and the home folding on the adapter prose the hosts view returns. The refusal code is now asserted, so the sentence stating it has a test. A CHANGELOG citation named a line number that has since moved; it names the function instead. Another said the withheld block always points at `second_brain_capabilities`, which the writer scope does not register. One "finally" in the README that read as a sales line is gone.

Three `no-await-in-loop` warnings came in with the tests this review added, taking the branch from main's 146 to 149. The two-view payload check parallelises cleanly. The two-spelling refusal check does not - `runCli` refuses a concurrent in-process run by name, because it swaps the environment, the working directory and both output streams - so those two cases are named calls to one helper rather than a loop.

Ticking 229 to 231 and 197 to 199 pushed one line to 86 columns in a paragraph wrapped at 78. The prose is unchanged; the wrap is. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
The per-scope census iterates `report.withheld` and asserts each name is absent from the body. Over an empty set it asserts nothing - and a capability window that stopped being honoured is precisely what produces an empty set, so the test would have passed on the regression it exists to catch. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
`.apb/` was untracked when this branch started and a wholesale stage in the review swept it in: the orchestrator's config, its workdir lock, and the playbook and profile definitions it runs from. None of it is part of a change about what an install knows. `.gitignore` already excludes `.apb/runs/` and `.apb/tmp/`, so the definitions under `.apb/playbooks/` and `.apb/profiles/` are trackable by design and may well deserve a commit - but that is a decision of its own, not a side effect of this one. The files stay on disk exactly as they were; the branch stops carrying them. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
A plain prefix replacement run under `/home/dev` would clip `/home/developer` in the same sentence into `~eloper` - a path naming no file, which is worse than either the raw one or the folded one. The home now matches only where the next character cannot continue a directory name, so it still folds before a separator, before punctuation and at the end of a sentence, and leaves a sibling alone. The fall-through in the `ConfigReadError` branch says at the site what the docblock says above it: an unreadable config is not consent to print host paths. And `instructions.ts` had a docblock left dangling over nothing when its constant moved to the module that owns it. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
Both were caught by the full suite, and both are the census working. `tests/cli/manifest-completeness.test.ts` reads the dispatcher with `case "([^"]+)":`, so naming the version case through a constant made the case invisible to it and the manifest entry read as stale. The case is a string literal again, like every sibling, with the reason written where someone would next be tempted. The constant stays for the flag-to-verb rewrite, where nothing scrapes it. `tests/core/hygiene/hardcoded-paths.test.ts` scans shipped surfaces for home paths and does not exempt comments - correctly, since a path in a docblock is still a path someone will copy. The new docblock illustrated the sibling-clipping case with two literal ones; it names the directories instead. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
The handshake renderer emits the capability-report pointer only when the report says second_brain_capabilities is available, because the writer scope never registers it. docs/mcp.md still claimed the tool is "never itself withheld" and the block always points there, which is the defect the conditional pointer removes, restated in the document explaining it. Verified against the running server: with brain_note disabled, the full and catalog scopes close the block with the pointer and the writer scope closes it with the names. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
`What is new` still opened on 1.54.0. The 1.55.0 wave updated the highlights list further down and left the lead paragraphs alone, so the section named a version two releases behind `package.json`. The 1.56.0 lead replaces it: the version verb with its root synonym and the one constant behind both surfaces, `second_brain_wiring` with its two views and the path policy both answers obey, and the handshake instructions rendered from the capability window this server evaluates and never consulted. A second paragraph records that nothing here computes a new fact, what the card reading refuted, and the one card refused rather than built. 1.55.0 and 1.54.0 compress into the single line the section's older entries already use, which is also where the skipped 1.55.0 entry lands. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
`vaultPathField` became `hostPathReference` applied to the vault, and the bundle still carried the old function. The CI step that rebuilds `src/openclaw/index.ts` and diffs it against the committed artifact would have failed this pull request; it exists precisely so a stale bundle is caught here rather than on a release tag.

omitted tool is callable. Preserve the existing tools/call and tools/list
behavior described by the filtered this.tools table.
In `@src/mcp/tool-contract.ts`:

existing installation_secret is available, return an unresolved field instead of
generating or persisting configuration. Preserve the resolveExposeHostPaths path
behavior.
- Line 109: Update the ConfigReadError handling in the vault path field flow to

instead of passing err to unresolvedField. Preserve existing handling for other
error types.
In `@src/mcp/wiring-tools.ts`:

Bun runs the whole suite in one process, and `tests/setup.ts` makes it hermetic by pointing OPEN_SECOND_BRAIN_CONFIG at a throwaway config for every file that does not set its own. This suite set that key for one test and `delete`d it in a local `finally`, so it did not restore a prior state - it destroyed the process-wide default for every file bun scheduled after this one. Two suites landed on the wrong side of that ordering in CI and in no local run: `cmdBrainDigest` resolves its vault before parsing `--window` and threw "no vault configured" instead of exiting 2, and `vault_health` read a config the fixture had not written, so two state surfaces reported origin `user-config` against an expected `default`. Every key the file writes is now snapshotted in `beforeEach` and put back in `afterEach`, including the config path, so the restore is a value rather than a removal. The unreadable-config test also asserts `vault_ref` alongside `project_ref`: the two fields are rendered by the same call, so an assertion over one of them passes for a payload that leaked the other.

…llable The catalog body told every agent that every tool omitted from tools/list stays CALLABLE through tools/call. That is true of the tools the catalog surface hides - it marks them `hidden` and leaves them in the table - and false of the ones a runtime capability window withholds: `evaluateToolCapabilities` removes those from the table `tools/call` routes on, so calling one answers `unknown tool`. Carrying that sentence unchanged into a rendering whose entire subject is the capability window ships a handshake that contradicts the runtime it was rendered for, which is the defect this release exists to remove, one paragraph over. The sentence now separates the two reasons a tool can be absent from tools/list and says which of them ends callability. The pinned `catalog.txt` fixture carries the corrected text. Byte identity with the frozen strings is the invariant that fixture exists to hold, so the exception is declared rather than absorbed: in the fixture test, in the module that renders the body, in docs/mcp.md, in the README and in the CHANGELOG. `advertised_tool_count` gets the same treatment in the smaller: the window is applied before the count, so seven is the no-window figure and a window withholding one of the seven lowers it. The docblock and the matching docs/mcp.md paragraph now say so, and name the capability diagnostic as the one tool no window withholds. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>
When the device-local config cannot be read, `hostPathReference` reports the condition in the field instead of raising, because raising there took down whole diagnostic payloads on their last field. The reason it carried was `ConfigReadError`'s own message, which names the config path twice - once in the condition and once in the `chmod` remedy. That message is right on the four channels it was written for: a CLI refusal, an MCP error envelope, a hook's stderr, and the two read-only diagnostics whose whole job is to name the broken file. This is none of them. It is the field forty-five tools emit into model context precisely so that an absolute path under the operator's home does not travel there, so reporting the condition by naming that path reintroduced, in the degraded branch, the leak the resolved branch prevents. The field now carries a path-safe reason and points at `second_brain_status`, which still names the file - as does `vault_health`'s `config_writeable` check, from the same payload. The diagnostics keep `unresolvedField`, which is unchanged. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>
…ounded `second_brain_wiring` takes a preview-budget exemption, and the reason it gave said both views are bounded by construction. That holds for `view=hosts` - one entry per adapter in a registry this build closes - and not for `view=projects`: nothing caps `projects.json`, every `o2b brain project link` appends to it, and the serialized result went inline into model context at whatever size the registry had grown to. The list is now capped at twenty-five and carries `total`, `returned` and `truncated` beside it - the same self-declaring shape the page-lint report uses, so a capped answer cannot be read as a complete one. Capped rather than budgeted because `previewBudget` is per tool, not per view. The shared budget is around 2000 characters and the hosts view renders about 1700 with nothing installed, so adopting it would park an operator's connector diagnostic in an artifact on nearly every call - a cost paid by the view that never needed bounding. The CLI verb is left uncapped: it renders to a terminal, not into model context. The exemption reason now states what actually bounds each view.

`openclaw/index.js` inlines `src/mcp/vault-path-field.ts`, so the path-safe unreadable-config reason from c262168 has to be rebuilt into it - which is the point of that module: a contract honoured on one runtime and not the other is the defect it exists to close. The bundle now carries the same reason the MCP surface does, and drops the `unresolvedField` call it no longer makes. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>
`pruneWriteImages` kept every image whose measured age came back
negative. `fileAgeMs` deliberately does not clamp - a file stamped ahead
of the clock is a real condition it reports rather than hides, and there
is a test pinning that - so `msToWholeDays` took -1ms to -1 whole day,
which is below every retention window including zero.
The condition is ordinary, not exotic. `nowMs` is sampled once before
the sweep, and mtime granularity on a synced or networked filesystem
rounds a write made just before it up past that sample. It turned CI
red on this branch on one image of two:
PRUNE removed= 1 kept= 1
reproduced deterministically by stamping one of two images 50ms ahead.
The same family failed on main's latest CI run, on the neighbouring
`--older-than-days 0` case.
The floor goes at the call site rather than in `fileAgeMs`, because a
non-negative age is part of what RETENTION means and not part of what
the measurement reports. The staged test replaces waiting for the race.

`attaching an observer changes nothing the pass writes` compares two vault trees and already normalises the snapshot archive's `size_bytes`, because a tar carries the mtimes of the tree it was taken from and the two copies straddle a second under load. The day log's chain hashes are computed over the payload INCLUDING that real size, and every later line chains off the first through `prev`. So normalising the field alone left the nondeterminism in the two places the field had just been removed from, and one straddled second re-keyed the entire file. It passed on every developer box and failed on a loaded CI runner, which is where it failed here. `h` and `prev` are now normalised alongside the size. The chain is not left unguarded - the log-integrity suites verify it end to end - and what this test asserts is that the observer changed nothing the pass AUTHORED, which is the payloads. `prev: null` is a literal, not a digest, and is left alone.

Summary
An operator with a shell can now ask which version of Open Second Brain is installed, and an agent on the MCP surface can ask which projects point at this vault and whether the hosts this install wrote registrations into can still be reached. The first block of text every agent reads at connect time is no longer three frozen strings chosen by scope alone: it is rendered from the capability window this runtime actually evaluated, so guidance for a tool this host withheld is removed rather than contradicted. Nothing here computes a new fact - four surfaces start reading what four typed readers already produce.
