// aidlc-knowledge.ts — the DocumentKB tool: index a customer's documents into a
|
|
// committed, searchable catalog.
|
|
//
|
|
// Two directories, and the split between them is load-bearing:
|
|
// knowledge/documents/ USER-managed originals. Their folder structure is
|
|
// theirs — nested by topic, by customer, however they
|
|
// like — and this tool NEVER reorganises it.
|
|
// knowledge/documentkb/ TOOL-managed, derived, and safe to rebuild from
|
|
// documents/ at any time.
|
|
//
|
|
// That gives the invariant the whole design rests on: documentkb/ is
|
|
// RECONSTRUCTIBLE. Delete index.json and `sync` rebuilds it from documents/ plus
|
|
// each surviving document's own metadata.json. Nothing unrecoverable lives only
|
|
// in documentkb/.
|
|
//
|
|
// NOT from the audit ledger, which an earlier draft of this comment claimed:
|
|
// rebuildIndex() reads the filesystem only, and the sole audit call in this file
|
|
// is the WRITE side. The distinction matters for what a reader expects to
|
|
// survive -- deleting a per-document metadata.json really does lose that row's
|
|
// tombstone, and no ledger replay brings it back.
|
|
//
|
|
// Every write goes through the journaled transaction: take the workspace lock,
|
|
// stage outside it, re-validate the source digest inside it, then `rename()` the
|
|
// finished tree in as the single commit point. An earlier draft of this comment
|
|
// said `onboard` "writes directly, which is why it is not yet safe under
|
|
// concurrency" — true when it was written, stale since the transaction landed.
|
|
//
|
|
// THE READ BOUNDARY. Every path this tool touches came from somewhere it does
|
|
// not control — a CLI argument, a directory walk, or a committed index row — so
|
|
// four shared guards apply, and none is optional:
|
|
// 0. THE ANCHOR ITSELF is trusted first (assertKnowledgeRootTrusted): no
|
|
// container on the way down to documentkb/ may be a symlink;
|
|
// 1. the shape is validated (aidlc-documentkb-schema.ts): relative, POSIX,
|
|
// no `..`, no NUL, real digests;
|
|
// 2. no path COMPONENT is a symlink (assertNoSymlinkInChainOrThrow) — a walk
|
|
// that validates a container and then trusts its contents will read a
|
|
// symlinked file inside an already-trusted directory;
|
|
// 3. containment is re-checked AFTER realpathSync, the contained identity is
|
|
// retained, and readRegularFileNoFollowOrThrow requires the opened
|
|
// descriptor to match it before reading.
|
|
//
|
|
// Steps 2 and 3 are separate on purpose. A containment check on the resolved
|
|
// leaf answers "does this land inside?" but not "did we travel through
|
|
// something that can be repointed later".
|
|
//
|
|
// Step 0 was MISSING until 2026-08-08, and its absence made steps 1-3 decorative
|
|
// on the write path: they all protect paths BELOW an anchor that was itself
|
|
// resolved with realpathSync and then trusted. A symlink AT `documentkb/` was
|
|
// therefore obeyed, and a measured `onboard` wrote the whole catalog outside the
|
|
// project (and, pointed inward, into the user's own documents/). Guarding the
|
|
// contents of a container you have not verified is guarding the wrong thing.

*
|
|
* Built here rather than by calling `auditFilePath(pd, undefined, space)`, and
|
|
* the reason is a measured trap. `undefined` does NOT mean "no intent" to that
|
|
* helper -- it means "resolve one from the cursor": `auditFilePath` -> `recordDir`
|
|
* -> `activeIntent`, which falls back to the active-intent pointer and then to a
|
|
* lone intent. The space shard is only reached when `recordDir` returns null,
|
|
* i.e. when the space has no intents at all. So a first probe in an empty space
|
|
* looks correct and the same call starts filing into `intents/<slug>/audit/` the
|
|
* moment any intent exists.
|
|
*
|
|
* That is exactly what the first build of this transaction did. DocumentKB rows
|
|
* MUST NOT land in an intent's shard: a document outlives any intent, and
|
|
* `associate`/`dissociate` can move its scope later -- filing its provenance
|
|
* under whichever intent happened to be active would split one document's
|
|
* history across shards and make it unreconstructible.
|
|
*
|
|
* `intentsDir()` IS the space record root (`spaceRecordRoot` is a private alias
|
|
* for it), so this composes the same path the null branch of `auditFilePath`
|
|
* composes, without touching shared code.

* THE WRITE-SIDE FUNNEL for every mutable path under `documentkb/`.
|

|
|
* `assertKnowledgeRootTrusted` anchors the chain down to `documentkb/` ITSELF,
|
|
* but a container can be trusted while what's INSIDE it is not: `.journal` or a
|
|
* document id directory can independently be a symlink, planted after
|
|
* `documentkb/` was created honestly. Measured against the shipped tool
|
|
* (2026-08-11):
|
|
*
|
|
* documentkb/.journal -> /outside `collectStaleJournals` (called from
|
|
* both `sync` and standalone) `rmSync`ed
|
|
* an external victim file THROUGH the
|
|
* link, exit 0, "Up to date."
|
|
* documentkb/<id> -> knowledge/documents `sync`/`associate`/`rebind` wrote
|
|
* `content.md` and `metadata.json` into
|
|
* the user's OWN originals folder.
|
|
*
|
|
* So containment must be re-checked per COMPONENT of the requested descendant,
|
|
* exactly like `resolveContainedPath` already does for a read — this is that
|
|
* same discipline applied to the write side. `journalDir`, `journalTxnDir` and
|
|
* `documentDir` below are the intended path-builders for every mutation under
|
|
* `documentkb/`; today every `mkdirSync`/`rmSync`/`renameSync`/`writeFileAtomic`/
|
|
* `writeBufferAtomic` target below `documentkb/` is `join()`'d off one of their
|
|
* return values (or off the bare, unextended `documentkbDir()`/`indexPath()`
|
|
* anchor). That is a fact about the CURRENT body of this file, not a property
|
|
* this function enforces — nothing here stops a future export from calling an
|
|
* fs primitive directly against a hand-built path under a different name.
|
|
* `documentDir`, `journalDir` and `journalTxnDir` are convenient, not
|
|
* mandatory: a rename defeats "convenient" every time. What actually catches a
|
|
* new unguarded call site is
|
|
* `tests/unit/t289-knowledge-onboard-boundary.test.ts`'s pinned COUNT of raw fs-
|
|
* mutation calls plus a per-call-site provenance trace back to the funnel or
|
|
* the bare anchor — routed around the parameter/name a call happens to use,
|
|
* not keyed to it. A miscounted or unrouted new call site fails that test, not
|
|

* replacing the link would destroy whatever it pointed at.
|

|
|
* Called from every command handler AND from inside each exported entry point
|
|
* (`onboard`, `syncDocuments`, `listDocuments`, `showDocument`,
|
|
* `setIntentAssociation`, `rebindDocument`). Both, deliberately: the handler call
|
|
* fails early, before `--intent` resolution does any work, and the in-function
|
|
* call is what protects a caller who imports the module and skips `main()`
|
|
* entirely. Review measured that bypass -- an in-process `onboard()` against a
|
|
* redirected `documentkb` wrote the catalog off-project with the handler guard in
|
|
* place -- and while no in-repo caller does that today, these signatures take a
|
|
* plain `(projectDir, space)` and give a future importer no hint that anchoring
|
|
* is required. Cheap (a handful of `lstat`s) and idempotent, so paying for it
|
|
* twice per invocation costs nothing worth measuring.
|
|
*
|
|
* SCOPE, stated rather than implied: this catches a symlink that is present when
|
|
* the command starts. It is not a defence against a race -- an attacker who can
|
|
* plant a symlink DURING the run, between this check and a later write, wins, and
|
|
* closing that would mean re-anchoring after every intermediate mkdir and rename
|
|
* inside the transaction. That residual risk is accepted: it requires a process
|
|
* already co-resident on the filesystem and timing a several-hundred-millisecond
|
|
* window, which is a far stronger position than the threat actually defended
|
|
* here -- a hostile branch, tarball, or clone that lands a symlink before anyone
|
|
* runs anything.
|
|
*
|
|

* Repair a document's identity after a change the tool refuses to guess at.

* `rebind` is not a convenience -- it is the required counterpart to failing
|
|
* closed. With only {path, sha256} there is genuinely no information
|
|
* distinguishing "moved and edited policy.pdf" from "deleted policy.pdf and added
|
|
* an unrelated standards.pdf". A heuristic would silently re-point identity, and

|
* because a rule's citation hangs off that identity, a wrong guess
|
|
* MIS-ATTRIBUTES A POLICY.
|
|
*
|
|
* Failing closed is only defensible if the human has a way to resolve what the
|
|
* tool refused, which is this. Without it, an edited-and-moved document is
|
|
* permanently stranded and the only remedy is re-onboarding under a NEW identity
|
