Core packages live under `internal/`; domain types and ports are in `internal/domain/`, capability packages include `ingest`, `search`, and `analysis`, and MongoDB/Qdrant adapters live in `internal/storage/`. Templates and assets are under `internal/web/`. Unit tests sit beside their packages; tagged end-to-end tests are in `tests/`. Project documentation and ADRs live in `docs/`; deployment files are in `deploy/`. + +## Build, Test, and Development Commands + +- `make setup`: download Go modules, install development tools, and create `.env` from `.env.example`. +- `make compose-up`: start MongoDB, Qdrant, and Ollama; run `make models` once. +- `make dev`: run the application from source at `http://127.0.0.1:8080`. +- `make build`: create the static binary at `bin/relata`. +- `make test`: run unit tests with the race detector; `make test-short` is faster. +- `make test-integration`: run tagged integration tests using disposable service containers. +- `make check`: run formatting, linting, and unit-test checks. + +## Coding Style & Naming Conventions + +Target Go 1.26.5 or newer. Use tabs as emitted by `gofmt`; run `make fmt` before committing. `make lint` applies `go vet` and `staticcheck` when installed. Follow Go naming: exported identifiers use `PascalCase`, internal identifiers use `camelCase`, and packages are short lowercase nouns. Domain ports must not depend on HTTP, database, or provider-specific types. Treat model output and documents as untrusted input. + +## Testing Guidelines + +Use Go's `testing` package and name cases `TestBehavior`; prefer table-driven subtests where useful. Keep unit tests beside implementation as `*_test.go`. Add cross-service tests to `tests/` with the `integration` build tag. Run `make test-security` for auth, workspace isolation, input-handling, or rendering changes. Use `make test-cover` for coverage and `make fuzz` after parser or validation changes. There is no fixed coverage threshold, but changed behavior needs regression coverage. + +## Commit & Pull Request Guidelines + +History contains only `first commit`, so no mature convention exists. Use a concise imperative subject such as `Harden upload filename validation` and keep commits focused. Pull requests should explain the effect, approach, and tests run; link issues or ADRs. Include screenshots for template/CSS changes and call out configuration, migration, security, or API impacts. + +## Security & Configuration + +Never commit `.env`, tokens, keys, uploaded data, or build artifacts. Add settings to `.env.example`, validate safe defaults, redact secrets from logs, and preserve workspace filtering in storage operations. diff --git a/Dockerfile b/Dockerfile new file mode 100644 index 0000000..4ab8377 --- /dev/null +++ b/Dockerfile @@ -0,0 +1,67 @@ +# Relata production image. +# +# Multi-stage: a full toolchain builds a static binary, and the runtime stage +# contains that binary, CA certificates and nothing else.

It worked, +but it would not have survived a reboot — and Relata is enabled at boot and depends on it, so a +restart would have brought the site up with no embedding and no analysis. + +It is now `ollama.service`, enabled, with the 6.8GB model store moved from `/home/andy/.ollama` +to `/usr/share/ollama/.ollama` where the service's own user can read it. `relata.service` +declares `After=ollama.service`. + +**Models stay resident for 30 minutes** (`/etc/systemd/system/ollama.service.d/keep-alive.conf`). +Measured on this host: an answer takes **47s cold and 17s warm**, and almost all of the +difference is loading 5.2GB of `llama3.1:8b`. The default of 5 minutes expired between one +question and the next, so nearly every answer paid the load. The two models total ~5.8GB +against 31GB of RAM. + +**The Cloudflare real-IP snippet is deliberately NOT included.** With the hostname grey-clouded, +`$remote_addr` is already the true client. That snippet trusts `CF-Connecting-IP` from any +Cloudflare address — with no Cloudflare proxy actually in front, anyone willing to route a +request through a Cloudflare Worker could then set their own address and give themselves a +fresh login-rate-limit bucket. + +**If this hostname is ever put back behind the orange cloud, re-add the include.** Without it +every request would appear to come from a Cloudflare edge node and rate limiting would bucket +the whole internet together. + +**nginx adds no security headers.** Relata sets its own CSP, X-Frame-Options, +X-Content-Type-Options and Referrer-Policy on every response. `add_header` in nginx appends +rather than replaces, and two conflicting X-Frame-Options headers are worse than one. + +**Two locations have long timeouts.** `GET /search` and `POST /api/v1/search/answer` run a +language model inside the request. Everything else gets 120s. + +## Known constraints + +### Answer generation is slow, because this host has no GPU + +8 cores, 31GB RAM, CPU-only inference. Measured with `llama3.1:8b`: + +| | Time | +|---|---| +| Answer, model warm | ~17s | +| Answer, model cold | ~47s | +| Full ingestion pipeline, one short note | ~120s | + +Ingestion is asynchronous — jobs run in the background and nobody waits — so 120s is a +non-issue. Answer generation is synchronous and is what a person actually feels. + +A second Ollama container would not change any of this: same CPU, same weights, plus several +gigabytes of duplicated model store. What would: + +1. A GPU. That is the whole of the gap. +2. `RELATA_ANALYSIS_MODEL=llama3.2:3b` — several times faster, noticeably worse, and the + safeguards still hold (an uncited answer is downgraded, a schema-echo answer is rejected). +3. `RELATA_SEARCH_ANSWER_MAX_CHUNKS=4` to send the model less material. + +### Cloudflare (resolved, but worth knowing) + +Both of the following applied while `relata.dixon.cx` was proxied, and are the reason it is now +grey-clouded. They return the moment the orange cloud goes back on: + +- **Non-browser clients are challenged.** Requests without a browser get `403` with + `cf-mitigated: challenge` at the edge. This is zone-wide on `dixon.cx` — `grafana.dixon.cx` + and `intel.dixon.cx` behave the same way; `blackwall.cx` has an exception. API tokens are + unusable through it. +- **A 100-second proxy timeout** on non-enterprise plans, which cannot be raised from the + origin, returns 524 for a slow answer even though nginx and Relata would both have waited. + +If you want the proxy back for its other benefits, both are fixable from the Cloudflare +dashboard: a **WAF → Custom rules → Skip** matching +`(http.host eq "relata.dixon.cx" and starts_with(http.request.uri.path, "/api/v1/"))` skipping +*Managed Challenge* and *Bot Fight Mode*, and either keeping answers under 100s (see above) or +accepting that they will be cut off. Re-add `snippets/cloudflare-realip.conf` to the site at the +same time. + +### Everything else + +- **First sign-in provisions a private workspace.** Each Blackwall identity gets its own, and + relationship discovery never crosses between them.

That removes an entire class of ID-mapping bugs and makes +"delete this item's vectors" a filter rather than a join. + +Chunk IDs are **deterministic** — derived from `(workspace, item, sequence, content_hash)` — +so re-chunking an unchanged item reuses the same point IDs and overwrites the vectors rather +than orphaning them. + +### The three unique indexes that carry the weight + +These are not merely constraints; they are what make the pipeline idempotent under +concurrency. + +- **`entities (workspace, normalised_key)`** — one entity per normalised name and type. + Concurrent workers extracting the same company from different documents converge on one + record instead of racing to create two. Similar-but-different names never collide here; + they produce a candidate alias for a person to adjudicate, and even a confirmed alias + leaves both records in place. +- **`relationships (workspace, dedupe_key)`** — the key is derived from the endpoint pair, so + reprocessing updates an existing relationship rather than adding a parallel one. Crucially, + the upsert **refuses to overwrite a human review decision**: if someone has confirmed, + rejected or edited it, only the evidence is refreshed. +- **`jobs (idempotency_key)` where `status = "pending"`** — a partial index, so at most one + *pending* job may exist per key while completed jobs remain as history. Re-enqueuing after + a crash is a no-op rather than duplicate work. + +### Workspace enforcement + +Every user-content record carries `workspace_id`, and every repository method takes one. The +helper `wsFilter` is the only sanctioned way to begin a filter and **returns an error on an +empty workspace**, so a missing principal cannot silently widen a query. + +There is deliberately no `GetByID(id)` that skips the workspace. Cross-workspace access +returns `not_found`, never `forbidden`, so probing cannot confirm that an ID exists elsewhere. + +### Qdrant payloads + +Only what retrieval needs: + +``` +workspace_id · item_id · chunk_id · source_type · created_at · embedding_model +``` + +No text, no titles, no relationship data. Keeping the payload thin is what stops Qdrant +drifting into a second, unversioned copy of the corpus.

Nothing external is needed to detect the crash. + +**Losing a lease cancels the work.** If a heartbeat finds the lease gone — another worker has +taken over — the job's context is cancelled so the original worker abandons its attempt +instead of writing a stale result. + +**Two independent limits.** Worker count bounds concurrent jobs; a separate semaphore bounds +concurrent AI calls. A small local model is not swamped just because the worker count was +raised. + +**Only transient failures retry.** Invalid model output, an unparseable document, a missing +handler and a deleted item are permanent — repeating them wastes the queue. Transient +failures retry with bounded exponential backoff and full jitter, within an attempt budget. + +**A panicking handler does not take the worker down.** Handlers run guarded; a panic becomes +an ordinary job failure. + +**Shutdown drains.** The HTTP server stops accepting first, then workers are given until the +shutdown deadline.

Each now has a regression test. + +1. **Worker deadlock.** `execute` waited for the heartbeat goroutine to exit, while that + goroutine's only exit was the job context being cancelled — which happened via `defer` + *after* `execute` returned. Every worker wedged after one job; three workers meant three + stuck jobs and a queue that never drained. Found by watching the queue page stop moving. + `TestWorkerCompletesJobsAndDoesNotDeadlock` queues more jobs than there are workers. + +2. **Dates leaking into figures.** The number pattern could begin at the whitespace *before* a + date and take `202` out of `2025-02-10`. The overlap check tested only the match's start + offset, so the fragment survived and was then compared against other documents' quantities — + manufacturing contradictions between documents that agreed. Found by reading the evidence + behind a suspicious `contradicts`. Fixed by testing the whole span. + +3. **Mirror-image relationships.** The dedupe key included endpoint order, so a link found + while processing A and rediscovered while processing B became two records. Every pair in + the demonstration set was duplicated. `PairKey` now normalises the order. + +4. **Incomparable ranking curves.** Scaled contributions (entity match, relationship + expansion) used `weight × strength / 15` while ranked contributions used + `weight / (60 + rank)`. A full-strength expansion therefore outranked a direct keyword hit — + "related to a match" beating "is a match". Both now sit on the same reciprocal-rank curve. + +5. **Duplicate detection that a race could defeat.** Exact-duplicate detection read the + content hash and then inserted, with only a non-unique index underneath. Eight concurrent + uploads of identical content stored four items each claiming to be the only one — so + "an identical item already exists" was simply untrue under load. Found by writing the + concurrency test rather than by observing it. The fix puts the guarantee where it belongs: + a partial unique index on `(workspace_id, content_hash)` covering live, non-deliberate + items, with the insert's duplicate-key error reported as exactly the same `DuplicateError` + the check produces, so callers see one answer regardless of which path caught it. + Deliberate duplicates carry `duplicate_of` and sit outside the constraint. + +6. **A useless model answer failed the whole request.** Adding degeneracy validation to model + output surfaced this: `Answer` returned `nil, err` for any generation failure, discarding + the retrieved sources and the recorded contradictions between them. Both are produced + deterministically and neither depends on the model, so the one case where a user most needs + to read the sources themselves was the case that showed them nothing. Invalid output now + degrades — no prose, sources and conflicts retained, rejection reason stated — matching the + no-material and no-readable-text paths beside it. A timeout or unreachable provider still + errors, because that is an operational condition rather than a bad answer. + +A seventh, found by fuzzing rather than running: the Markdown parser set a heading block's `Text` +to the trimmed line while its offsets spanned the untrimmed one, breaking the invariant that +`block.Text == doc.Text[block.Start:block.End]` — on which every claim and entity source +reference depends. The failing input is retained as a corpus seed. + +### Deliberate changes from the plan + +- **`MaxUnreviewedScore = 0.95`.** Not in the original design. Without it a candidate with + enough accumulated signals reached 1.00 — the same score as a human confirmation — and the + interface presented them identically. That conflates "much evidence" with "confirmed", which + is the distinction the whole design exists to preserve. +- **Alias signals require a *confirmed* alias.** The plan listed `alias_entity` as a signal + without saying which aliases counted. Using unconfirmed candidates would have made a guess + into evidence, defeating the point of proposing aliases for review. +- **Claim subjects moved to a two-sided rule.** For a value the subject precedes the figure + ("the cost is £42,000"); for a quantity it follows ("ship 240 **units**"). The one-sided + rule produced subjects like "ship" and "ltd", which paired unrelated claims. +- **A model that says "unrelated" no longer also contributes its type suggestion.** Both + signals were being recorded, so a model could simultaneously argue against and for a link. +- **No `scripts/openapi` generator.** The specification is hand-written and a test asserts it + matches the routes the router actually registers, plus every enum and error code. A + generator would have produced a specification that could only agree with itself. + +### Verified, with the caveats that apply + +Run against MongoDB 7, Qdrant 1.12, and Ollama with `nomic-embed-text` and `llama3.1:8b` on a +CPU-only machine. + +- The full pipeline completes for all eleven demonstration documents. +- The two superficially similar depot reports acquire **no** relationship, and the note sharing + only the entity "Example Ltd" acquires none either — sharing wording, or an entity, is not a + relationship. +- The cost contradiction is detected deterministically, with both figures named, and is + surfaced in generated answers **independently of what the model says**. +- Deleting an item leaves no orphaned vectors, chunks, claims or entities. +- Reprocessing twice changes no derived-record count, and a human review decision survives it. +- Two Relata instances against one MongoDB cooperated correctly through the leased queue — + unplanned, but a genuine test of the lease design. + +Known weak points are listed in the README rather than here, so that a reader meets them +before they meet a surprise. diff --git a/docs/INGESTION_PIPELINE.md b/docs/INGESTION_PIPELINE.md new file mode 100644 index 0000000..47c5140 --- /dev/null +++ b/docs/INGESTION_PIPELINE.md @@ -0,0 +1,273 @@ +# Ingestion pipeline + +From "a user pastes a note" to "the note has evidence-backed relationships". + +The governing rule: **the original is preserved.** Whatever a user supplies is stored verbatim +before any parsing is attempted.

It +may be innocent, or it may be an attempt to smuggle one format past a check for another; either +way it is visible. + +--- + +## Stage 1 — Parse + +`internal/parsing`, handler in `pipeline.go` + +Opens a **processing run**, then extracts text from the preserved original. + +| Format | Approach | Retains | +|---|---|---| +| Plain text | Paragraph splitting on blank lines; RFC-822 headers recognised as a block | Paragraph offsets | +| Markdown | Line-based structural parse: headings, lists, fences, quotes, tables | Heading hierarchy as a section path | +| JSON | Depth-bounded streaming scan, then flattening to `path: value` lines, keys sorted | Object boundaries as sections | +| PDF | Page by page; a page that fails is skipped with a warning | Page numbers | +| DOCX | Streaming XML over `word/document.xml`; Word heading styles → structural headings | Heading hierarchy | + +Every block records **byte offsets into the extracted text**, and the invariant +`block.Text == doc.Text[block.Start:block.End]` holds. Every derived record's source +reference depends on that identity; it is asserted in unit tests and fuzz-tested. + +**Failure behaviour.** A parse failure is *not* a job failure. The warning is recorded, the +item is marked `failed`, the original is untouched, and the job returns successfully — the job +did its work correctly, and retrying would only repeat the same failure. The user sees the +warning on the item and can reprocess after fixing the cause. + +**Quality warnings** raised here: +- `low_extractable_text` — a large file yielding almost no letters, usually a scan. Relata does + not OCR, and says so rather than silently indexing nothing. +- `truncated_text` — output exceeded the configured limit; blocks past the cut are dropped and + the straddling one clamped, so offsets stay valid. +- `json_depth_exceeded` — nesting or width beyond the limit. +- `parse_failed` — recorded per page for PDFs, or for the whole document. + +--- + +## Stage 2 — Chunk + +`internal/chunking` + +Structure first, character counts only as a ceiling. + +**Rules, in order:** + +1. A document below `RELATA_CHUNK_MIN_SPLIT_CHARS` becomes **one chunk**. Splitting a + two-sentence note produces fragments that embed worse than the whole. +2. A heading starts a new chunk, once the current one is large enough to stand alone. +3. A page change (PDF) is a real boundary. +4. A JSON object boundary is respected once the chunk has reached its target size. +5. Adding a block that would exceed `RELATA_CHUNK_MAX_CHARS` starts a new chunk. +6. A single block larger than the ceiling is split internally, preferring blank lines, then + sentence terminators, then line breaks, then word breaks. +7. Chunks below `RELATA_CHUNK_MIN_CHARS` are merged into a neighbour. + +**Overlap.** Each chunk after the first extends backwards by up to +`RELATA_CHUNK_OVERLAP_CHARS`, aligned to a word boundary, so a sentence spanning a boundary is +retrievable from both sides. The chunk's `Start` moves back with it, so +`chunk.Text == text[Start:End]` still holds; `OverlapChars` records how much was borrowed. + +Each chunk stores: parent item, sequence, source offsets, page, section, heading, text, +content hash and (after embedding) the embedding model. + +**Chunk IDs are deterministic** — derived from `(workspace, item, sequence, content_hash)` — so +re-chunking unchanged content reuses the same Qdrant point IDs and overwrites vectors rather +than orphaning them. Before writing new chunks, the item's existing vectors are deleted. + +--- + +## Stage 3 — Embed + +`internal/embeddings` + +- Chunks are embedded in batches of `RELATA_EMBED_BATCH_SIZE`. +- An **AI semaphore** is held for the duration of the provider call, so concurrent model usage + stays within `RELATA_AI_CONCURRENCY` regardless of worker count. +- **Dimension validation.** The first response fixes the width; a later mismatch is a + *permanent* error, because writing differently-sized vectors into one collection would + corrupt it. The error names the fix. +- **Bounded retry.** Only transport failures and explicitly transient HTTP statuses retry, with + exponential backoff and full jitter, within `RELATA_AI_MAX_RETRIES`. A 400 or an unknown + model never retries. Jitter matters because the worker pool dispatches in parallel: without + it, a provider restart would be met by every worker retrying in lockstep. +- Vectors go to Qdrant with the minimal payload; chunks are marked embedded with the model name. +- **Document text is never logged.** + +--- + +## Stage 4 — Entities + +`internal/entities` + +Two stages, separately labelled so a user can tell a matched pattern from a model's guess. + +**Deterministic** (`method = deterministic`) — narrow by design, because a pattern that fires +on ordinary prose would flood the index and make shared-entity evidence meaningless: + +- organisations ending in a legal suffix (`Ltd`, `PLC`, `GmbH`, `Inc`, …) +- people preceded by an honorific (`Dr`, `Prof`, `Ms`, …) +- email addresses +- dates in ISO, `14 March 2025`, `March 14, 2025` and `14/03/2025` forms, **normalised to + ISO-8601** (day/month/year for the ambiguous numeric form, matching the application's + British English conventions) + +**Model-assisted** (`method = model`) — broader concepts, over a bounded sample of chunks. +Output is enum-validated per row; one bad row is skipped rather than invalidating the response. +A claimed evidence quotation that does not appear in the source is **dropped**, because a +fabricated quotation would break the promise that source references point at real text. + +**Resolution.** Entities are keyed on `(workspace, type, normalised_name)` and merged only on +an **exact** key match. Normalisation is shallow — case folding, whitespace, punctuation, +apostrophes, diacritics — and deliberately does *not* strip legal suffixes: "Example Ltd" and +"Example Holdings Ltd" are different companies far more often than they are typos. + +Names that look alike produce a **candidate alias** for a human to confirm, using a looser key +plus token overlap, edit distance and acronym detection. Nothing is merged automatically. + +Every mention carries item-relative byte offsets and the verbatim quote. + +--- + +## Stage 5 — Claims + +A claim records that a source **said** something. It is not a fact, and it never loses its link +to the original text. + +**Deterministic** — sentences carrying a figure or a date, because those are the statements +that can actually agree or conflict with another source. Sentence splitting knows common +abbreviations, so "Ltd. reported" stays one sentence. + +For each, Relata derives comparison keys: +- **subject** — the content word governing the figure ("cost" in "the total project cost is + £42,000") +- **numbers** — currency- and separator-aware +- **dates** — normalised to ISO-8601 +- **polarity** — +1 affirmative, −1 negated + +**Model-assisted** — broader claims, with attribution and a `quoted`/`paraphrased`/`inferred` +nature. A claim whose quotation cannot be located in the source is **discarded**; whitespace +reflow is tolerated, because that locates the same span rather than inventing one. + +--- + +## Stage 6 — Discover relationships + +`internal/relationships/discover.go` + +**Candidates never come from an all-pairs comparison.** Three bounded, indexed sources: + +1. **Vector neighbours** — a sample of the item's chunks is embedded and searched, filtered to + the workspace and excluding the item itself. +2. **Shared entities** — an indexed aggregation over `entities.item_ids`, ordered by how many + entities are shared. Concepts are excluded as a *source* (too broad) while still + contributing a signal. +3. **Shared claim subjects** — an indexed lookup on `claims.subject`. + +The union is capped at `RELATA_REL_MAX_CANDIDATES` before any scoring or model call. + +**Evidence gathering** per candidate: shared entities (discounted by corpus frequency), +concept overlap, temporal proximity, shared metadata, claim comparison and content-hash match. + +**Claim comparison** is what makes "which sources disagree about the cost?" answerable without +a language model: two claims about the same subject with materially different figures (beyond +a 0.1% tolerance) or different dates are a **contradiction**, recorded with both quotations +attached. Matching figures are **support**. + +**Scoring**, then a bounded number of model classification calls — only for candidates that +already have real evidence, so model time is not spent on noise. The model contributes one +signal; a maximally confident opinion cannot on its own reach the storage threshold. + +**Storage.** Candidates below `RELATA_REL_STORE_SCORE` are discarded. The rest are stored as +`pending` review with full evidence. Non-directional types are stored in a canonical endpoint +order so A~B and B~A are one relationship. A near-duplicate (similarity above +`RELATA_NEAR_DUPLICATE_SIMILARITY`) is flagged with an explicit note — **never merged**. + +--- + +## Failure and recovery + +| Failure | Behaviour | +|---|---| +| Parse fails | Warning recorded, item marked `failed`, original preserved, job succeeds | +| Embedding provider down | Transient — retried with backoff, then the job fails and can be retried from the queue page | +| Model returns invalid JSON | Recorded with a reason, **not** retried; deterministic results are kept | +| Model unavailable | Entity and claim extraction degrade to deterministic only; the pipeline continues | +| Worker crashes | The lease expires and the job returns to the queue | +| Job exceeds its attempts | Marked failed; retryable manually | +| Item deleted mid-pipeline | Permanent failure — the stage stops rather than resurrecting derived data | + +--- + +## Reprocessing + +`RequestReprocess` opens a **new processing run** and restarts the chain at parsing, with the +run ID in the job's idempotency key so it is never suppressed as a duplicate of the original +ingest. + +Nothing multiplies: + +| Records | Why not | +|---|---| +| Chunks | Replaced wholesale | +| Vectors | Deterministic IDs; the item's vectors are cleared before re-chunking | +| Claims | Replaced wholesale; unique dedupe key | +| Entities | Upserted on the normalised key; observations accumulate | +| Relationships | Upserted on the dedupe key — and **a human review decision is never overwritten** | + +Previous processing runs are **retained**, recording the parser, embedding model, analysis +model and scoring version that produced each generation.

Making permission the *intersection* +with the owner's live role means one thing that a fixed grant cannot give: **demoting or +disabling a person immediately narrows or kills every token they hold**, without anyone having +to find those tokens. The user record is re-read per request precisely to make that true; a +role cached on the token would mean the change took effect at expiry, which is exactly when it +does not matter. + +### Tokens cannot manage tokens + +The single most valuable thing a leaked credential can do is make itself permanent. Requiring +an interactive session for creation, listing and revocation means a leaked token has a fixed +expiry it cannot extend, cannot mint replacements, and cannot revoke the tokens that would +replace it. + +### The CSRF exemption is about *how*, not *whether* + +Bearer requests carry no CSRF token, and should not have to: CSRF defends against a +third-party page spending *ambient* credentials, and an `Authorization` header is not ambient — +a browser never attaches one by itself. + +The dangerous way to implement that is to skip CSRF when an `Authorization` header is present, +because then any cookie-authenticated request can disable the check by adding one. So the +exemption keys off how the request actually authenticated, and authentication resolves the +session cookie **first**. A request holding a cookie is never token-authenticated, so the +header cannot switch anything off. This was verified against a running instance, not only +reasoned about. + +### Rejected: PATs that never expire + +Convenient, and the reason so many leaked credentials stay live for years. Every token has an +expiry, capped by configuration, and stops working with no further action. + +### Rejected: tokens in query parameters + +A token in a URL ends up in access logs, browser history, referrer headers and screenshots. +Only the `Authorization` header is read. + +## Consequences + +**Good:** a stolen database yields no usable credential; a role change takes effect instantly +across every token; a leaked token is bounded in scope, in lifetime and in what it can escalate +to. + +**Bad:** a lost token cannot be recovered, only revoked and replaced. Scopes are coarse — three +of them, checked per route, with no per-item restriction. Creating a token through the +interface puts its value in the browser's history for one page load, which the page warns +about; the API route returns it in a response body and avoids that entirely. diff --git a/docs/decisions/README.md b/docs/decisions/README.md new file mode 100644 index 0000000..24d27ec --- /dev/null +++ b/docs/decisions/README.md @@ -0,0 +1,19 @@ +# Architectural decision records + +One file per decision that would be expensive to reverse or surprising to encounter without +explanation.

The Relata API

+

+ Everything the interface does, /api/v1 does too. Authenticate with a bearer + token you create for yourself. +

+ +
+

Getting a token

+

+ Sign in, then go to Settings → API tokens. Choose a name, the scopes it + needs, and how long it should live. +

+

+ The token is shown once. Relata stores only a SHA-256 hash of it, so a + database read — or a backup — yields nothing that can authenticate. If you lose it, revoke + it and make another. +

+ +

Scopes

+ + + + + + + +
ScopePermits
querySearch, generate answers, and read stored items, entities and relationships.
ingestCreate items, upload files, reprocess and delete.
reviewConfirm, reject and retype relationships; confirm entity aliases.
+

+ A token never carries more than the role of the person who created it. The check is the + intersection of the two, so demoting someone immediately narrows every token they hold + without any of those tokens being touched. +

+
+ +
+

Using it

+ 
export RELATA_TOKEN='rlt_v1_...'
+
+# Search
+curl -s -H "Authorization: Bearer $RELATA_TOKEN" \
+  'https://relata.example/api/v1/search?q=delivery+schedule&limit=5'
+
+# Ingest a note
+curl -s -X POST -H "Authorization: Bearer $RELATA_TOKEN" \
+  -H 'Content-Type: application/json' \
+  https://relata.example/api/v1/items \
+  -d '{"title":"Meeting note","content":"The revised cost is 51,500.","source_type":"note"}'
+
+# Ask a question of what is stored
+curl -s -X POST -H "Authorization: Bearer $RELATA_TOKEN" \
+  -H 'Content-Type: application/json' \
+  https://relata.example/api/v1/search/answer \
+  -d '{"question":"What is the project cost?"}'
+ +

+ Bearer requests do not need a CSRF token: CSRF exists to stop a third-party page spending + ambient credentials, and an Authorization header is not ambient — a + browser never attaches one on its own. +

+
+ +
+

What a token cannot do

+
    +
  • Reach the web interface. Tokens authenticate /api/v1 only.
    • +
  • Manage tokens. Creating, listing and revoking tokens requires a + signed-in session, so a leaked token cannot mint its own replacements or extend its life.
    • +
  • Outlive its expiry or revocation. Both are checked on every request + against the stored record. There is no cached grant to wait out.
    • +
  • Exceed your role. Scopes narrow permission; they never widen it.
    • +
+
+ +
+

Errors

+

Every error is a stable code with a safe message and a request ID:

+ 
{
+  "error": {
+    "code": "insufficient_scope",
+    "message": "This API token does not carry the scope this request needs.",
+    "detail": { "required_scope": "ingest" },
+    "request_id": "b3f1c0d2-…"
+  }
+}
+

+ Rate limiting is per token. A token making too many requests gets 429 with + rate_limited; the limit resets on a fixed window. +

+
+ +
+

For operators

+

+ The redirect URI to register with your identity provider is: +

+ 
{{.CallbackURL}}
+

+ The path is fixed at /auth/oauth/callback; only the host varies. The full + OpenAPI specification is in the repository at docs/openapi.yaml. +

How Relata works

+

+ Ingest, derive, connect, retrieve — with the reasoning kept and shown at every step. +

+ +
+

The pipeline

+
    +
  1. Ingest. The original bytes are stored verbatim and never rewritten. + An exact duplicate is detected and reported rather than silently stored twice.
    2. +
  2. Parse. Text, Markdown, JSON, PDF and DOCX become extracted text plus a + structure map. The parser version is recorded on the item.
    3. +
  3. Chunk. Structure-aware splitting, so a chunk is a passage rather than + an arbitrary window. Chunk IDs are deterministic and double as vector IDs.
    4. +
  4. Embed. Each chunk is embedded locally; the model that produced each + vector is recorded, so a model change is visible rather than silent.
    5. +
  5. Extract. Entities and claims, deterministically where the text allows + and with model assistance where it does not — each labelled with which produced it.
    6. +
  6. Discover. A bounded candidate set is scored against explicit signals. + There is no all-pairs comparison and no unexplained number anywhere in it.
    7. +
+

+ Every stage is a queued job with a lease rather than a lock, so a worker that dies has its + work returned to the queue rather than holding it forever. +

+
+ +
+

How a relationship gets its score

+

+ The score is the weighted sum of the signals that fired, capped at 1.00, under a versioned + scoring model. Each signal is stored with its own value, strength and weight, so the total + is arithmetic you can check. +

+ + + + {{range .Weights}} + + + + + + {{end}} + +
SignalWeightWhat it means
{{.Signal}}{{printf "%.2f" .Weight}}{{.Means}}
+ +

Three deliberate judgements

+
    +
  • Similarity alone cannot look like evidence. Unrelated documents from + one corpus routinely sit at 0.5–0.7 cosine, so raw similarity carries almost no + information at the low end. It is rebased against a floor of 0.55 before it counts.
    • +
  • A model cannot manufacture a relationship. Its weight is below the + storage threshold, so a maximally confident classification still cannot create a link. + It can shape a relationship other evidence already supports.
    • +
  • Human decisions dominate. Confirmation saturates the score; rejection + drives it to zero. Neither deletes anything — the original proposal, its provenance and + its signals are all retained.
    • +
+ +

Diminishing returns

+

+ Repeated signals of one type contribute 1.0, then 0.5, then 0.25, then nothing. Breadth of + evidence beats repetition: a document mentioning one company twelve times should not + outrank one that relates on several independent grounds. +

+
+ +
+

Why each search result was returned

+

+ A query runs through several independent paths — keyword, vector, entity, title, and + expansion through relationships — each producing its own ordering. They are fused by + reciprocal rank rather than by adding scores, because a keyword score and a cosine + distance are not on comparable scales and whichever had the larger range would dominate. +

+

Every result carries its reasons in plain words:

+
    +
  • A section of this item is close in meaning to your query (similarity 0.89).
    • +
  • The item's text contains words from your query.
    • +
  • This item refers to Example Ltd (organisation), which your query names.
    • +
  • Not a direct match. Reached because this item updates a matching item — + strength 0.68 (suggested by analysis, not yet reviewed).
    • +
+

+ Relevance is normalised against the best result in the same response, so it is comparable + within one result set and not across queries. The interface says so rather than leaving you + to assume otherwise. +

+
+ +
+

Answers from stored knowledge

+

These hold regardless of what the model returns:

+
    +
  1. The model sees only retrieved passages, inside delimited untrusted blocks.
    2. +
  2. Passages are labelled S1, S2… — item IDs are never shown to + the model, so a fabricated citation cannot resolve to a real record.
    3. +
  3. An answer claiming sufficiency while citing nothing is downgraded to insufficient.
    4. +
  4. Contradictions Relata recorded between the retrieved items are surfaced + independently of the model's own account, so a model that quietly picked + a side cannot hide the disagreement.
    5. +
  5. Inferred relationships that influenced retrieval are listed as proposals, not facts.
    6. +
  6. If a passage tried to instruct the model, that is reported rather than hidden.
    7. +
  7. A model that returns nothing usable costs you the prose, not the retrieval: the sources + and conflicts still come back, with the reason the answer was rejected.
    8. +
+
+ +
+

Your workspace is your own

+

+ Each person who signs in gets a private workspace. No document, entity or relationship is + shared with anyone else, and the boundary is enforced in every storage query rather than in + a filter that could be forgotten. +

+

+ The cost is worth stating plainly: relationship discovery never spans users. + Two people who upload documents about the same contract get no link between them, because + as far as Relata is concerned they are separate corpora. +

+
+ +
+

Known limitations

+
    +
  • Scores are heuristic strengths, not calibrated probabilities. The weights were chosen by + judgement, not fitted to labelled data.
    • +
  • Deterministic entity extraction is narrow: organisations with a legal suffix, people + with an honorific, email addresses and dates. Broader coverage comes from the model stage + and is labelled as such.
    • +
  • Contradiction detection compares figures and dates about the same coarse subject. It + will not catch a contradiction expressed entirely in prose.
    • +
  • No OCR. A scanned PDF is preserved and flagged as having little extractable text.
    • +
  • Answer generation on a CPU-only machine is slow. A small model produces answers that + are often not worth reading, though the safeguards still hold.
    • +
  • Prompt-injection defences bound the damage; they are not a proof. Treat generated + answers as summaries of sources, not as authority.

Store what you know. Find out how it connects.

+
+ +
+

Three numbers, never mixed up

+

+ Most systems collapse "these documents read alike", "these documents are connected" and + "this document answers your question" into a single relevance figure. They are three + different claims with three different meanings, and Relata keeps them apart in storage, in + the API and on screen. +

+
+
+

Semantic similarity

+

How alike are these two pieces of text?

+

Cosine distance between embeddings. Nothing more. Two incident reports written by the + same team in the same house style will score highly and describe entirely different + events.

+
+
+

Relationship strength

+

How well evidenced is a link between two items?

+

A weighted sum of named signals, each stored with its own value and weight, so the + arithmetic is always inspectable. Not a probability.

+
+
+

Query relevance

+

How well does this item answer this question?

+

Several retrieval paths fused by rank. Comparable within one result set, not across + queries — and it says so.

+
+
+
+ +
+

Similarity is not a relationship

+

+ This is the distinction the whole design exists to preserve. Two documents that share + wording are not thereby connected; two documents that mention the same company are not + thereby about the same thing. Relata records what it actually found: +

+
+

+ Both figures are named. Relata does not decide which is correct. +

+
+
+ +
+

What a language model is allowed to do

+

+ A model may classify a relationship's type or describe a connection. Its opinion is + one signal, weighted 0.15 — below the threshold at which a relationship is + stored at all. A model cannot create a connection on its own, however confident it is. That + is a property of the arithmetic, not a promise, and there is a test asserting it. +

+ + + + + {{range .Weights}} + + + + + + {{end}} + +
Signal weights in relationship-score-v1
SignalWeightWhat it means
{{.Signal}}{{printf "%.2f" .Weight}}{{.Means}}
+
+ +
+

What it will not do

+
    +
  • It will not merge two entities because their names look alike. + "Example Ltd" and "Example Holdings Ltd" are different companies far more often than they + are typos of each other. Similar names become a candidate alias awaiting a person's + confirmation, and a confirmed alias still does not merge the records.
    • +
  • It will not infer causation from sequence. Two things happening in + order yields a chronological statement and nothing more.
    • +
  • It will not hide conflicting evidence. Contradictions between retrieved + documents are surfaced independently of what any model said about them.
    • +
  • It will not present an inference as a fact. Every discovered + relationship arrives as a proposal, labelled as one, and nothing is auto-confirmed.
    • +
  • It will not rewrite your originals. The bytes you supplied are stored + verbatim; everything else is derived and reproducible.
    • +
+
+ +
+

Honest about the limits

+

+ Relationship scores are heuristic strengths, not calibrated probabilities — the weights were + chosen by judgement, not fitted to labelled data. A 0.7 does not mean "70% likely to be + real". Deterministic extraction is deliberately narrow. There is no OCR. Prompt-injection + defences make injection much harder and bound its effect; they are not a proof. +

+

+ The full account is on the how-it-works page, including what is + verified and what is merely intended. +
