The fix moves the authoritative consent signal off the repo tree into a new **user-owned consent store** at `${GSD_HOME||homedir()}/.gsd/consent.json` (new leaf module `src/capability-consent.cts`): a bounded, non-throwing, atomically-written store keyed by `(realpath(projectRoot), capability id)`. The security binding is a **recomputed full-bundle content hash** (`bundleContentHash` — a `sha512` over *every* regular file in the bundle, manifest AND artifacts AND identity, symlinks and non-regular entries rejected, bounded), **not** the repo-plantable ledger `integrity` (which is `''` for path/git/dir installs — a degenerate `'' === ''`) and **not** the executable-only disclosure signature (which is constant for a declarative-only capability, so a repo-write attacker could swap `capability.json` for a malicious gate/contribution while consent still matched). The loader **recomputes** the bundle content hash at load and activates a project-scope overlay — declarative surfaces and command dispatch alike — only when it matches the consent record on **this** machine; any tamper (a swapped declarative manifest, an edited hook script, an empty-integrity local install) changes the hash and leaves the capability *discovered but inactive* (`gsd capability list` reports `status: inactive` with a reason). Global-scope overlays (under the user's own home) remain trusted without a per-project record. The lifecycle records consent (bound to the installed bundle's content hash) on a consented project install/upgrade and revokes it on remove, deriving the project root through one canonical helper (`consentProjectRoot`) shared by the install record site, the loader lookup, and `trust revoke`, so an install from a sub-directory is not immediately inactive. The disclosure signature now also covers each MCP server's `transport`/`url`/`headers` (non-stdio endpoints), `env`, `cwd`, and the *raw* args array, plus a command module's `router`, and every surface line is JSON-encoded (no delimiter-injection collisions) — so a swapped remote endpoint, header, environment (e.g. `NODE_OPTIONS=--require evil.js`), entry point, or non-string arg forces re-consent. The consent store serializes concurrent cross-project writes under a lockfile (no lost updates), enforces its record cap at write time, uses a collision-safe on-disk key for paths containing spaces, and tolerates a vanished directory on the durability fsync. New CLI: `gsd capability trust list` and `gsd capability trust revoke [--project ]`. The loader's per-scope ledger read now goes through the shared bounded fd reader (a repo-planted FIFO ledger can no longer hang the loader) and reuses the ledger's shared `isValidLedgerEntry` validator for committed-entry parity. Integration hardening: the overlay consumers (`capability-state`, `loop-resolver`, the federated config-loader/config-schema) now thread the consent home (`GSD_HOME`) explicitly to the loader so a consented project capability is never looked up at the wrong home; the loader's discovered-but-inactive warning carries a structural `kind: 'unconsented'` discriminant that `gsd capability list` filters on (rather than matching the reason prose); a reconcile rollback that deletes a project-scope bundle also revokes its now-stale consent so an identical re-drop stays inactive; `installCapability`/`upgradeCapability` warn on stderr when a project install supplies no consent store and when the consent-store write fails (the install still succeeds — a consent-store IO error never fails an otherwise-successful install); `gsd capability trust list` now exposes the stored `disclosureSignature` and `contentHash` for diffing; and when `GSD_HOME` resolves equal to a genuine project root an in-repo bundle still requires a consent record (it is not deduped as trusted-global). Convergence hardening: the content-hash canonicalization — the security binding itself — is now **injective and lossless**. It length-FRAMES every component (an entry count, then per entry a type tag, the uint32 path length + path bytes, and for files the uint64 content length + the **raw** content bytes read via a new raw-`Buffer` reader, never a lossy UTF-8 decode) so neither a `NUL` embedded in file content can fake a file boundary (the old `relpath + NUL + content + NUL` framing was non-injective) nor can two binary artifacts that differ only in invalid-UTF-8 bytes collide on `U+FFFD`; empty directories are bound via typed directory markers so adding/removing one changes the hash. `recordProjectConsent`/`revokeProjectConsent` now **throw** rather than perform an unlocked read-modify-write when the consent-store lock cannot be acquired (the lifecycle already treats a consent-write failure as non-fatal and warns, so an install still succeeds). The consent lock and the lifecycle lock are now ONE shared hardened primitive (`src/capability-lock.cts`) — process-start-time liveness identity + a hard deadman — so the consent lock can no longer stale-steal a slow-but-live writer (the old mtime-only 60 s steal could). Finally, the MCP disclosure signature now folds in a stable hash of the **full** server config object the writer persists (not only the whitelisted fields), so an upgrade that changes any host-honored field outside the whitelist (a future `envFile`/`workingDir`/launch option) still forces re-consent. A final convergence pass closes four residual gaps: (1) the loader's overlay-root dedup and the CB-3 "project root == global home ⇒ require consent" comparison are now keyed on `fs.realpathSync` (fail-safe to `path.resolve`), so a **symlinked `GSD_HOME` aliasing the project root** can no longer slip an in-repo bundle into the trusted-global slot — it still requires a consent record; (2) the loader reads `capability.json` through the shared **bounded** fd reader (regular-file + size cap) instead of a raw `fs.readFileSync`, so a project-planted FIFO/device or oversized manifest skips the overlay (warning) rather than hanging or OOM-ing the loop; (3) the **PATH** component of the content hash is now hashed from raw directory-entry **bytes** (a `{ encoding: 'buffer' }` walk, separator normalized at the byte level), so two bundle files whose names differ only in invalid-UTF-8 bytes (which a string decode would collapse to `U+FFFD`) no longer collide; and (4) the `gsd capability trust revoke` CLI now catches the consent-store lock-acquire failure and emits a clean, actionable error instead of surfacing a raw stack. A further convergence pass closes three more residual gaps and documents one irreducible limit: (1) the loader's user-owned consent gate now runs **before** the heavy pre-activation work (`materializeHookFragments` and cross-capability validation) for a project-scope overlay, so a forged in-repo bundle whose `fragment.path` points at an in-bundle FIFO/oversized file is skipped (unconsented → inactive) **without** ever reading that fragment — closing a pre-consent hang/OOM (the gate's decision is unchanged; only the work-ordering moved), and as defense-in-depth `materializeHookFragments` now reads each fragment body through the shared **bounded** fd reader (regular-file + size cap) so a FIFO/device/oversized fragment becomes an un-materializable-fragment validation error rather than a blocking read on any scope; (2) `gsd capability list` now reads each project `capability.json` through the same bounded reader instead of a raw `fs.readFileSync`, so a project-planted FIFO/device or oversized manifest omits that entry's metadata and exits cleanly rather than hanging/OOM-ing the list; (3) the loader's `canonicalDir` realpath **failure** is now strictly fail-safe — a candidate that would be classified trusted-`global` but whose `realpathSync` throws (a race/odd-FS, e.g. a symlinked `GSD_HOME` aliasing the project root) is reclassified conservatively to consent-required `project`, so it can no longer park an aliased project tree in the trusted-global slot (a non-existent global dir still resolves to a harmless no-op scan). Finally, an honest in-code comment at the loader consent gate documents the **irreducible filesystem-primitive TOCTOU residual**: the content hash binds the bundle at verification time, but a local writer racing between that verification and the capability's later execution can still mutate the bundle files — closing this window would require fd-pinned execution or an atomic content snapshot (native support not available at this layer); any persisted tamper is still caught on the next load (mirrors the #1462 lock-release residual — a documented real limit, not a dismissal). A final deep-convergence pass closes three more gaps: (1) the realpath fail-safe is now **two-sided** — a global overlay root is trusted (consent-free) ONLY when `realpath(global)` AND `realpath(project)` BOTH succeed AND resolve to DIFFERENT physical paths; the prior one-sided rule (demote only a realpath-failed *global* candidate) still let a **symlinked `GSD_HOME` aliasing the project root** bypass consent when the GLOBAL candidate realpathed fine but the PROJECT candidate's realpath failed (the keys never collided, so the in-repo bundle stayed in the no-consent global slot), so distinctness that cannot be proven (either side throws, or both resolve equal) now demotes the global to consent-required `project` whenever a genuine project root exists — while a genuinely non-existent project overlay (ENOENT) or a distinct real global root still stays trusted; (2) `bundleContentHash` now **bounds the enumeration itself** — it streams each directory via `fs.opendirSync` + `readSync` and throws the moment a cumulative entry counter exceeds the cap, BEFORE collecting/sorting a whole directory, so a malicious unconsented bundle with a huge single directory (or a deep tree) can no longer force unbounded memory/CPU before fail-closing (the cap is cumulative across the recursive walk; determinism is preserved by sorting the bounded set); and (3) a project `remove` no longer silently swallows the revoke-on-lock-failure throw — `revokeProjectConsent` throws on a consent-lock failure (a stale consent record a byte-identical re-drop could reactivate against), so `removeCapability` now surfaces it via a stderr warning naming the record AND a `consentRevokeFailed`/`consentRevokeWarning` flag on the result, which the CLI reports as a non-clean removal (telling the user to run `gsd capability trust revoke`). diff --git a/.gitignore b/.gitignore index 78ed6a695..2b265b76c 100644 --- a/.gitignore +++ b/.gitignore @@ -72,6 +72,8 @@ build/ /gsd-core/bin/lib/capability-ledger.cjs /gsd-core/bin/lib/capability-trust.cjs /gsd-core/bin/lib/capability-lifecycle.cjs +/gsd-core/bin/lib/capability-consent.cjs +/gsd-core/bin/lib/capability-lock.cjs /gsd-core/bin/lib/markdown-sectionizer.cjs /gsd-core/bin/lib/resolution.cjs /gsd-core/bin/lib/research-store.cjs diff --git a/CONTEXT.md b/CONTEXT.md index de4402cf4..71788c750 100644 --- a/CONTEXT.md +++ b/CONTEXT.md @@ -176,7 +176,7 @@ Generated central manifest projecting all co-located Capability declarations int ADR-857 phase 3b seam that merges capability-declared config slices into the `loadConfig` return value.

The MCP disclosure also captures each server's `env` (string→string, filtered) and `cwd` (#1459) — `disclosureSignature` folds them in as STABLE SORTED JSON so any env/cwd add/change forces re-consent while a key reorder does not; `signatureForManifest(manifest, stagedDir?)` is the single source of truth for that signature (consumed by the loader's consent check and the lifecycle's consent binding). #1459 finding 5: each MCP surface also carries `rawConfig` — the FULL declared server config the writer persists (`{...config}`), prototype-pollution-cleaned — folded into the signature as STABLE SORTED JSON so a change to ANY persisted field (not just the explicit whitelist — a future `envFile`/`workingDir`/launch option) forces re-consent, while a pure key reorder does not; the human summary stays readable via the key fields only. The barrier is consent + integrity + reversibility, NOT a sandbox — see `docs/explanation/capability-trust-model.md`. ### Capability Lifecycle ADR-1244 Phase 4 (D5+D6) orchestration seam (`gsd-core/bin/lib/capability-lifecycle.cjs`) composing the source resolver, ledger, and trust gate into the mutating operations. Exports: `installCapability` (pre-fetch source gate → resolve copy-only with `promote:false` → trust verdict → promote + apply marker-stamped shared edits → **ledger commit**; nothing written on block/abort), `upgradeCapability` (atomic stage-then-swap: old set aside, new swapped in, shared edits re-derived, **ledger committed**, backup dropped; re-prompts when the executable set changed), `removeCapability` (strip only `_gsdCapability`-marked shared-config entries — user hand-edits preserved — delete exactly the ledger-recorded files, then drop the entry; `CAPABILITY_DATA` preserved unless `removeData`), `reconcileCapabilities` (crash recovery driven by the ledger's `_pending {kind,backupName,sharedFiles}` INTENT — not a version comparison: roll an uncommitted upgrade back by restoring the backup, an uncommitted fresh install away entirely, and re-sync shared config from the winning bundle, guaranteeing no half-state), plus `applyCapabilitySharedEdits`/`stripCapabilitySharedEdits` (marker-isolated JSON edits, prototype-pollution-guarded). All four mutating ops + reconcile take a cross-process lock (`.gsd/capabilities/.lock`, atomic stale-steal) so a concurrent reconcile can't clear a live intent. Capability code never executes during any operation. The source resolver's `promote:false`/`skipEnginesGate` options are the seams that let this module own the swap/commit ordering and the engines gate (with `compatVersions` downgrade hint). ### Capability Command Dispatch -ADR-1244 Phase 5 (D7) registry-driven dispatch of capability command families. First-party families (`graphify`/`intel`/`audit`, shipped in `bin/lib/`) dispatch via `dispatchCapabilityCommand` (`gsd-core/bin/gsd-tools.cjs`) against the FROZEN `capability-registry.cjs` `commandFamilies` (confined to `bin/lib/`) — unchanged. Third-party (installed overlay) families dispatch via `dispatchOverlayCapabilityCommand`: after the first-party path returns false, it calls `loadRegistry({ includeInstalled, cwd })` and dispatches a family iff its `capId` is in `_overlay.commandRoots` — which `capability-loader.cjs` populates ONLY for accepted overlay capabilities that (a) declare `commands` AND (b) have a **committed** ledger entry (present, non-`_pending`); a bundle dropped on disk with no ledger entry is NOT command-dispatchable (consent gate).

Project-scope ledgers live in the repo tree and are only as trustworthy as the repo — see `docs/explanation/capability-trust-model.md` "project-scope trust boundary". +ADR-1244 Phase 5 (D7) registry-driven dispatch of capability command families. First-party families (`graphify`/`intel`/`audit`, shipped in `bin/lib/`) dispatch via `dispatchCapabilityCommand` (`gsd-core/bin/gsd-tools.cjs`) against the FROZEN `capability-registry.cjs` `commandFamilies` (confined to `bin/lib/`) — unchanged. Third-party (installed overlay) families dispatch via `dispatchOverlayCapabilityCommand`: after the first-party path returns false, it calls `loadRegistry({ includeInstalled, cwd })` and dispatches a family iff its `capId` is in `_overlay.commandRoots` — which `capability-loader.cjs` populates ONLY for accepted overlay capabilities that declare `commands` AND pass the loader's activation gate (a **committed** ledger entry, present and non-`_pending`, PLUS — for PROJECT scope — a matching user consent record in the Capability Consent Store; GLOBAL scope needs no consent record). A bundle dropped on disk with no install (no ledger entry) or no on-this-machine consent is NOT command-dispatchable. The router module is `require()`'d FROM the capability's install root via `defaultRequireFromInstallRoot` (bare-`.cjs` basename + `realpath` containment, rejecting `..` traversal and symlink escape); same own-property/function/sync-only guards as the first-party path. Wired into the `runCommand` default arm before "Unknown command". A repo-planted project ledger no longer activates anything on its own (#1459) — see `docs/explanation/capability-trust-model.md` "project-scope trust boundary". ### Loop Extension Point A named, stable site on a host loop step (per-step `pre`/`post` plus per-wave in Execute; 12 total) where Capabilities register hooks. Three hook kinds: `step` (runs as its own sequenced unit), `contribution` (injects into the core step's prompt/context), and `gate` (checks and optionally blocks via a declared `blocking` flag). Each hook declares the artifacts it produces and consumes; hook order is derived by topological sort of that produces/consumes graph (capability-id tiebreak), which also defines data flow — file-artifact based, surviving `/clear` and fresh executor contexts. Hooks are surfaced by runtime resolution with concrete projection: the workflow calls a query that resolves the active hooks and returns fully-rendered, ordered markdown for the executor. Failure is default-resilient — a non-gate hook that errors is skipped with a warning; a hook may opt into `onError: halt`. Part of the Capability system. ADR-857 phase 3c ships the registry-consuming query layer: `gsd-core/bin/lib/loop-resolver.cjs` exposes `resolveLoopHooks({ point, registry, config })` (pure, no I/O), `renderLoopHooks(resolved)` (pure markdown renderer), and `cmdLoopRenderHooks(cwd, point, raw, opts)` (I/O entry point); activated via `gsd-tools loop render-hooks ` which emits `{ point, activeHooks[], rendered }`. Activation is driven by `when` (dotted config key resolved against `loadConfig`), with inline literal `__proto__`/`constructor`/`prototype` prototype-pollution guard. The first phase-6 cutovers wiring workflows to this query have landed — ui-phase at `plan:pre` and ui-review at `verify:post` (in `plan-phase.md`/`autonomous.md`); further per-feature cutovers are ongoing. diff --git a/docs/INVENTORY-MANIFEST.json b/docs/INVENTORY-MANIFEST.json index f67e27086..7993ca302 100644 --- a/docs/INVENTORY-MANIFEST.json +++ b/docs/INVENTORY-MANIFEST.json @@ -279,9 +279,11 @@ "audit-command-router.cjs", "audit.cjs", "capability-activation.cjs", + "capability-consent.cjs", "capability-ledger.cjs", "capability-lifecycle.cjs", "capability-loader.cjs", + "capability-lock.cjs", "capability-registry.cjs", "capability-source.cjs", "capability-state.cjs", diff --git a/docs/INVENTORY.md b/docs/INVENTORY.md index b6c7fbf38..ccfb97d5f 100644 --- a/docs/INVENTORY.md +++ b/docs/INVENTORY.md @@ -390,7 +390,9 @@ Full listing: `gsd-core/bin/lib/*.cjs`. | `audit-command-router.cjs` | ADR-959 capability command router for `gsd-tools audit-uat` and `gsd-tools audit-open` — extracted from hardcoded cases in `gsd-tools.cjs`;
