sim bbc3f131be refactor(#4653): make containment ONE decision, resolved two ways
Satisfies #4653 DW1 and DW9, which were the phase's outstanding acceptance
criteria: every other implementation must be deleted or route its containment
DECISION through the canonical predicate, and no surviving wrapper may decide
WHETHER a path is contained.

Three implementations were being retained with their own comparisons, on the
argument that each needs LEXICAL resolution — a realpath-based predicate is the
wrong tool wherever a symlink must be preserved rather than resolved. That
argument is correct about RESOLUTION and was being used to justify owning the
DECISION too. Those are separable, and separating them is what closes the
criteria honestly rather than by reinterpretation.

  isContainedIn(resolvedTarget, resolvedRoot, pathImpl?)   module-internal

is now the single place this repo decides containment. It is separator-aware, so
a sibling merely sharing a prefix (`<root>-evil` against `<root>`) is still
rejected. Two exported families sit on it and differ ONLY in how a candidate is
resolved before the decision:

  assertWithinRoot / tryWithinRoot                realpath-resolving
  assertWithinRootLexical / tryWithinRootLexical  path.resolve only, no I/O

The lexical pair carries `opts.pathImpl`, so win32 separator semantics stay
testable off Windows — that seam already existed in isPathConfined and would
have been lost by a naive collapse.

The three call sites now take their decision from the predicate and keep only
what is genuinely theirs:

  external-descriptor-trust isPathConfined   delegates outright; pathImpl forwarded
  installer-migrations ensureInsideConfig    delegates; keeps its own message and
                                             its LEXICAL fullPath, which callers
                                             consume for existsSync and journal rows
  gsd-tools.cjs isInsideDir                  delegates; keeps its own `target !==
                                             root` condition, and the separate
                                             symlink refusal above it stands

DW5 is not weakened by this. That criterion binds the symlink oracle and the
ancestor canonicalization; both are untouched. The only change inside
validatePath is three comparison lines becoming one call, and the rejection
string `Path escapes allowed directory: <resolved> is outside <base>` stays
byte-identical because it is an observable CLI contract.

What this does NOT do, stated plainly: the lexical family still cannot see a
symlink. That is a property of lexical resolution, not a gap in the seam, and
the three callers that need it are the three that must pair it with their own
symlink refusal — which is exactly what the fix earlier in this phase added at
the install sites. The doc comment says so at the definition, and CONTEXT.md and
docs/explanation/security-model.md are corrected: they previously described
these three as deliberately NOT routed through the predicate, which is no longer
true.

// here — NOT in the capability registry (ADR-959's commandFamilies is reserved
// for toggleable feature capabilities: graphify/audit/intel). A host command
// like `state` is core, non-toggleable, carries no tier/activationKey, so it
// cannot be a capability. Each entry maps a top-level command to its standard
// `route*Command` router (the same routers the hardcoded `case` arms called).
// Consulted in runCommand's `default` case, after capability + overlay
// dispatch, before the unknown-command error. A migrated command's `case` arm
// is removed at cutover so it reaches here; an unmigrated command still hits
// its `case` (collision structurally impossible, same property as ADR-959).
// ─── ADR-2346 P3: resolve/git/config/research host routers ────────────────
// Each body was relocated VERBATIM from its `case` arm (cutover: the arm is
// removed so dispatch reaches HOST_COMMAND_ROUTERS). Closures over module-
// scope libs (commands/config/output/error/_dispatchNonFamily) are preserved;
// only per-dispatch values (args/cwd/raw/defaultValue/workstreamContext)
// arrive via the destructured context.

// (#3045 CORE REDESIGN): correct for executor dispatch, where the record
// must be structurally unskippable — but wrong for a read-only
// diagnostic. A health check that records a phase:null/plan:null
// sentinel can hard-block every executor dispatch for the sentinel's
// lifetime, across sessions sharing the main checkout. Inspection
// surfaces call this verb instead. Two claims, both narrower than
// "side-effect-free", and both exactly true (#2486 review, Majors 2 & 4):
//
// 1. SENTINEL-FREE, not write-free. This route writes nothing itself, and
// in particular never writes .gsd/dispatch-isolation-sentinel.json —
// the only write that can hard-block a later executor dispatch. It is
// NOT an unconditional claim of total filesystem purity: like every
// gsd-tools invocation, it runs the shared bootstrap and
// active-workstream resolution first. As of #3579's root-cause fix
// that bootstrap resolves via the non-mutating peekActiveWorkstream
// (never unlinks); an actual stale/invalid pointer is still
// self-healed, but only by whichever verb's own getActiveWorkstream
// call later consumes it for real — this inspection route makes no
// such call, so it is now also side-effect-free on the pointer file.
//
// 2. SHARED NEGOTIATION, for the arguments this verb accepts. Both verbs
// call resolveDispatchIsolationDecision, so the natural resolution
// cannot drift. It is NOT a claim of byte-identical output for every
// argv: routeDispatchIsolation applies --force-isolation AFTER the
// shared helper returns, so the same argv could otherwise yield
// 'none' there and the declared capability here. Rather than let a
// caller receive a silently different answer, this verb REJECTS the

// false for a pi install, so the ENTIRE gsd-hooks/ tree — including any
// user-added file inside it — was invisible to detect-custom-files and
// therefore never backed up before the next clean-install wipe (silent
// data loss).
//
// Resolution order, mirroring bin/install.js's own resolveSharedHooksDirName:
// 1. Read the per-install runtime marker written by the installer at
// <configDir>/gsd-core/.gsd-runtime (#2297).
// 2. Look up that runtime's `hostBehaviors.sharedHooksDirName` in the

// module in the same installed tree as this file). Deliberately NOT
// `require('bin/install.js')`: that file is never shipped into an
// installed tree (the #3024/#2071 bug class), so only the shipped data
// module is read here.
//
// Asymmetric fallback: when the runtime or its descriptor cannot be
// determined (an install predating the marker, an unreadable/corrupt
// registry, or an unrecognized runtime id) this does NOT guess a single
// name — it returns every known candidate name instead. Over-scanning is
// safe here: a candidate directory that does not exist is silently skipped
// by the caller's `fs.existsSync` guard, and a file already tracked in the

// every call — it never reads the committed docs/CONTEXT-INDEX.json (that
// artifact is a CI drift-guard byproduct, not a query source, so it can
// never go stale relative to the live predicates it answers about).
//
// Selectors: --class <CLASS>, --prefix <dotted.prefix>, --contains <text>.
// At least one is required. When more than one is given they are ANDed
// together — the same documented precedence selectPredicates() itself
// implements (see context-predicates.cjs doc comment: "Select predicates
// by one or more optional criteria (ANDed together)"); no selector is
// silently dropped or overridden by another.
//
// Flag parsing mirrors routePromptBudget's Map-based flagMap: the three
// known flags are recognized in both the space-separated `--flag value`
// form and the inline-assignment `--flag=value` form (the latter is the
// escape hatch for a flag-shaped selector value, e.g. `--contains=--dry-run`
// — #2928 review finding C; the space-separated form has no such escape by
// design, since a following `--...` token always reads as a missing value).
// `--class=` (empty value) and `--class==A` (double-equals typo shape)
// are rejected the same way under either form. On a duplicate flag the
// FIRST occurrence wins (`Map.set` only fires when the key is absent),
// which is deterministic across repeated invocations with identical argv.
//
// Prototype-pollution safety: selector values are only ever compared via
// `===`/`.startsWith()`/`.includes()` against ordinary string fields — this
// route never uses a user-supplied string as an object property key
// (`obj[userValue] = ...`), so `--class __proto__` / `constructor` /
// `prototype` are just non-matching ordinary strings, not property-access
// vectors. `flagMap` itself is a `Map`, immune to prototype pollution by

* #3275: resolve a DECLARED command name to the file a spawn can actually start.
*
* Lane descriptors (src/review-lane-descriptor.cts) declare BARE, platform-unaware
* binary names ('codex', 'gemini', 'kimi', 'agy'), and `review-lane invoke`'s
* `deps.spawn` + `deps.hasBinary` both need the on-disk form of that name. Before
* this helper existed they disagreed: `hasBinary` scanned PATH WITH PATHEXT (so
* probes reported lanes AVAILABLE on Windows) while `spawn` received the bare name
* — `CreateProcess` performs no PATHEXT resolution, so every spawn-transport lane
* ENOENT'd there, and the #3086 `.cmd`/`.bat` cmd.exe mediation gate never fired
* because the declared name never carried an extension. One shared resolver is the
* only shape that cannot drift back apart.
*
* win32: tries PATHEXT entries ONLY — never the bare name. npm global installs
* drop an EXTENSIONLESS POSIX sh shim (`...\npm\codex`) next to `codex.CMD`; a
* bare-name-first scan resolves to it, the mediation gate sees no `.cmd`, and the
* ENOENT returns unchanged (field-reported on Windows 11 — see the #3275 issue
* comment pinning exactly this pitfall).
*
* POSIX: answers EXISTENCE only (the old `hasBinary` contract, preserved
* byte-for-byte) by scanning PATH for the bare name. `deps.spawn` does NOT consult
* this on POSIX — the bare name goes to spawnSync unchanged and Node's own PATH
* search does the work, so macOS/Linux behavior is untouched (#3275 acceptance).
*
* Path-like names (any '/' or '\') bypass the PATH scan: the name is already an
* address, so it passes through when the file exists and is a file.
*
* #3411: the scan itself now lives in the declared platform seam
* (`src/shell-command-projection.cts` → `resolveExecutableBinary`). This function is
* the `bin/` entry point onto it and holds no copy of the logic — `CONTEXT.md`
* declares that file "All OS-facing I/O; single platform seam", and a private
* duplicate here is what made it untrue.

// hand-rolling a `command -v timeout` probe per file.
//
// Exit-code contract (kept identical to GNU `timeout` so the existing per-site
// dispatch — `-eq 124` for timeout, `-eq 0` for pass, non-zero for fail — is
// unchanged):
// • command exits normally → exit with the command's own code
// • wall-clock budget exceeded → exit 124
// • command killed by a signal → exit 128+signum
// • command not found / not exec → exit 127 / 126 (spawn ENOENT / EACCES)
// • bad wrapper args → exit 2 (usage — a workflow-authoring bug)
