From 32cd2d2453ef6b5e1cf552e8e14e9f73e69dacf9 Mon Sep 17 00:00:00 2001 From: Mathews-Tom Date: Fri, 17 Apr 2026 13:21:12 +0530 Subject: [PATCH 01/11] chore(labels): add click and filelock dependencies plus labeling config surface MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit augur-labels needs click for the annotator CLI and filelock for the append-only parquet writer's per-partition locking. Declare both in the workspace member's pyproject and regenerate uv.lock. Also depend on augur-signals so the labeling package can import MarketSignal for the signal-to-event join without duplicating the model. config/labeling.toml mirrors the per-source credentials, workflow thresholds, storage paths, and join parameters from docs/methodology/labeling-protocol.md. LabelingConfig composes the per-block Pydantic sub-models with frozen, extra=forbid, and bounded numeric fields so a malformed config fails at startup rather than silently coercing. Credential env var names — not the secrets themselves — are stored in the config; the adapters read the secret from os.environ at startup. --- config/labeling.toml | 42 +++++++++++ src/augur_labels/augur_labels/_config.py | 91 ++++++++++++++++++++++++ src/augur_labels/pyproject.toml | 3 + uv.lock | 18 +++++ 4 files changed, 154 insertions(+) create mode 100644 config/labeling.toml create mode 100644 src/augur_labels/augur_labels/_config.py diff --git a/config/labeling.toml b/config/labeling.toml new file mode 100644 index 0000000..e34aaad --- /dev/null +++ b/config/labeling.toml @@ -0,0 +1,42 @@ +# Labeling pipeline configuration.

17 00:00:00 2001 From: Mathews-Tom Date: Fri, 17 Apr 2026 13:22:39 +0530 Subject: [PATCH 02/11] feat(labels): add pydantic data contracts for events, sources, annotations MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Five frozen Pydantic models mirror the schemas in docs/methodology/labeling-protocol.md: QualifyingSource and SourcePublication enforce the closed source_id literal set (reuters, bloomberg, ap, ft) so every downstream consumer — the workflow enforcer, the storage schema, the join — operates on the same tag set. Adding a source requires a protocol-version bump per the labeling-protocol doc. EventCandidate holds the intermediate state before two annotators agree; NewsworthyEvent is the labeled output the calibration layer consumes through the signal-to-event join. The status literal is closed at {labeled, candidate, superseded, rejected} — the corpus is append-only and corrections produce new rows with a corrects back-reference, not in-place mutation. LabelDecision records one annotator's call on one candidate. The qualifies-specific fields (timestamp, market_ids, category) are optional on the model; the workflow enforcer validates them at promotion time so an annotator can record "does not qualify" without fabricating event metadata. AgreementReport structures the four-metric agreement summary for CLI and CI consumption. --- .../augur_labels/models/__init__.py | 23 ++++ .../augur_labels/models/agreement.py | 29 ++++ .../augur_labels/models/annotation.py | 43 ++++++ src/augur_labels/augur_labels/models/event.py | 46 +++++++ .../augur_labels/models/source.py | 40 ++++++ tests/labels/test_models.py | 129 ++++++++++++++++++ 6 files changed, 310 insertions(+) create mode 100644 src/augur_labels/augur_labels/models/__init__.py create mode 100644 src/augur_labels/augur_labels/models/agreement.py create mode 100644 src/augur_labels/augur_labels/models/annotation.py create mode 100644 src/augur_labels/augur_labels/models/event.py create mode 100644 src/augur_labels/augur_labels/models/source.py create mode 100644 tests/labels/test_models.py diff --git a/src/augur_labels/augur_labels/models/__init__.py b/src/augur_labels/augur_labels/models/__init__.py new file mode 100644 index 0000000..f35ee8a --- /dev/null +++ b/src/augur_labels/augur_labels/models/__init__.py @@ -0,0 +1,23 @@ +"""Data contracts for the labeling pipeline. + +Exports the Pydantic models every other augur_labels module relies on. +Schema semantics are authoritative in +docs/methodology/labeling-protocol.md. +""" + +from __future__ import annotations + +from augur_labels.models.agreement import AgreementReport +from augur_labels.models.annotation import AnnotatorIdentity, LabelDecision +from augur_labels.models.event import EventCandidate, NewsworthyEvent +from augur_labels.models.source import QualifyingSource, SourcePublication + +__all__ = [ + "AgreementReport", + "AnnotatorIdentity", + "EventCandidate", + "LabelDecision", + "NewsworthyEvent", + "QualifyingSource", + "SourcePublication", +] diff --git a/src/augur_labels/augur_labels/models/agreement.py b/src/augur_labels/augur_labels/models/agreement.py new file mode 100644 index 0000000..82ad8cb --- /dev/null +++ b/src/augur_labels/augur_labels/models/agreement.py @@ -0,0 +1,29 @@ +"""AgreementReport — inter-annotator agreement metrics. + +Produced by the workflow enforcer before candidate promotion and by +the agreement CLI command for retrospective analysis.

The annotator CLI's discover command iterates over the adapters registered per config/labeling.toml and merges their output into candidate publications without caring about source-specific request shapes or auth flows. Each concrete adapter — ReutersAdapter, BloombergAdapter, ApAdapter, FtAdapter — reads its credentials from the env vars documented in phase-2 §5.2 and fails loud at construction when required credentials are missing, rather than silently returning an empty list on first call. The FT adapter is the exception: without an API key it returns an empty list and health_check False, matching the doc's RSS-fallback semantics. sources/_http.py provides request_with_backoff, a parametrized exponential-backoff helper (1 s initial, 60 s cap, 5 retries) that every adapter routes its HTTP calls through so retry semantics stay consistent across sources. Tests cover the happy path, the exhaustion path with injectable sleep, and the per-adapter credential-enforcement behavior. --- .../augur_labels/sources/__init__.py | 3 + .../augur_labels/sources/_http.py | 54 ++++++++ src/augur_labels/augur_labels/sources/ap.py | 83 ++++++++++++ src/augur_labels/augur_labels/sources/base.py | 39 ++++++ .../augur_labels/sources/bloomberg.py | 118 ++++++++++++++++++ src/augur_labels/augur_labels/sources/ft.py | 98 +++++++++++++++ .../augur_labels/sources/reuters.py | 88 +++++++++++++ tests/labels/test_sources.py | 91 ++++++++++++++ 8 files changed, 574 insertions(+) create mode 100644 src/augur_labels/augur_labels/sources/__init__.py create mode 100644 src/augur_labels/augur_labels/sources/_http.py create mode 100644 src/augur_labels/augur_labels/sources/ap.py create mode 100644 src/augur_labels/augur_labels/sources/base.py create mode 100644 src/augur_labels/augur_labels/sources/bloomberg.py create mode 100644 src/augur_labels/augur_labels/sources/ft.py create mode 100644 src/augur_labels/augur_labels/sources/reuters.py create mode 100644 tests/labels/test_sources.py diff --git a/src/augur_labels/augur_labels/sources/__init__.py b/src/augur_labels/augur_labels/sources/__init__.py new file mode 100644 index 0000000..96fd51b --- /dev/null +++ b/src/augur_labels/augur_labels/sources/__init__.py @@ -0,0 +1,3 @@ +"""Source adapters for the four qualifying wire services.""" + +from __future__ import annotations diff --git a/src/augur_labels/augur_labels/sources/_http.py b/src/augur_labels/augur_labels/sources/_http.py new file mode 100644 index 0000000..e04c028 --- /dev/null +++ b/src/augur_labels/augur_labels/sources/_http.py @@ -0,0 +1,54 @@ +"""Shared httpx client helpers with exponential backoff. + +Every source adapter routes its calls through ``request_with_backoff`` +so retry semantics stay consistent: 1 s initial delay, doubling to a +60 s cap, 5-retry max on any exception.

AppendOnlyParquetWriter groups incoming events by the date of their ground_truth_timestamp, acquires a filelock on the partition's lock file, reads the existing parquet (if any), appends the new rows, and atomically replaces the target via a staging-file-plus-rename. Concurrent annotator processes can call append() safely without corrupting the file. supersede() implements the protocol's correction path from docs/methodology/labeling-protocol.md §Annotator Protocol: it finds the partition containing event_id, flips status to superseded, sets the corrects back-reference, and rewrites the partition in place (still under the filelock). KeyError is raised when the event_id is absent, preventing silent no-op corrections. LabelReader uses partition-name-range pruning: only date=YYYY-MM-DD partitions in the requested window are opened, so the window query does not scan the full archive. events_for_market and coverage_by_category are built on top of events_in_window. _schema.py freezes the pyarrow schema matching the table in docs/methodology/labeling-protocol.md §Storage Schema verbatim. Schema changes require a label_protocol_version bump. mypy's disallow_any_unimported is relaxed for the three storage modules because pyarrow has no published type stubs. Every other invariant (strict everywhere else, Pydantic models round-tripped through the pipeline) still holds. --- pyproject.toml | 18 +++ .../augur_labels/storage/__init__.py | 3 + .../augur_labels/storage/_schema.py | 29 ++++ .../augur_labels/storage/parquet_writer.py | 129 ++++++++++++++++++ .../augur_labels/storage/reader.py | 96 +++++++++++++ tests/labels/test_parquet_writer.py | 123 +++++++++++++++++ 6 files changed, 398 insertions(+) create mode 100644 src/augur_labels/augur_labels/storage/__init__.py create mode 100644 src/augur_labels/augur_labels/storage/_schema.py create mode 100644 src/augur_labels/augur_labels/storage/parquet_writer.py create mode 100644 src/augur_labels/augur_labels/storage/reader.py create mode 100644 tests/labels/test_parquet_writer.py diff --git a/pyproject.toml b/pyproject.toml index d386d8a..bf95622 100644 --- a/pyproject.toml +++ b/pyproject.toml @@ -66,6 +66,24 @@ explicit_package_bases = true module = ["uuid_extensions.*"] ignore_missing_imports = true +[[tool.mypy.overrides]] +module = ["pyarrow.*"] +ignore_missing_imports = true + +[[tool.mypy.overrides]] +module = ["filelock.*"] +ignore_missing_imports = true + +# pyarrow has no type stubs; relax the no-any-unimported gate for the +# storage modules that pass pyarrow types across their public surface. +[[tool.mypy.overrides]] +module = [ + "augur_labels.storage._schema", + "augur_labels.storage.parquet_writer", + "augur_labels.storage.reader", +] +disallow_any_unimported = false + [tool.pytest.ini_options] testpaths = ["tests"] asyncio_mode = "auto" diff --git a/src/augur_labels/augur_labels/storage/__init__.py b/src/augur_labels/augur_labels/storage/__init__.py new file mode 100644 index 0000000..d6136d0 --- /dev/null +++ b/src/augur_labels/augur_labels/storage/__init__.py @@ -0,0 +1,3 @@ +"""Append-only Parquet storage for the labeled corpus.""" + +from __future__ import annotations diff --git a/src/augur_labels/augur_labels/storage/_schema.py b/src/augur_labels/augur_labels/storage/_schema.py new file mode 100644 index 0000000..7d881d8 --- /dev/null +++ b/src/augur_labels/augur_labels/storage/_schema.py @@ -0,0 +1,29 @@ +"""Pyarrow schema for newsworthy_events.parquet. + +Columns mirror the table in docs/methodology/labeling-protocol.md +§Storage Schema verbatim.

It pairs two annotators' decisions by candidate_id — decisions on candidates only one annotator reviewed are excluded — and computes four metrics against the targets in docs/methodology/labeling-protocol.md §Inter-Annotator Agreement. Event-existence kappa and category-assignment kappa use Cohen's kappa: observed agreement minus chance-expected agreement, scaled by (1 - expected). When the population is perfectly concentrated on one label (so expected == 1.0) the function returns 1.0 instead of dividing by zero. Timestamp agreement counts the fraction of paired qualifying decisions whose timestamps fall within the 60-second window. Market-association Jaccard averages |A ∩ B| / |A ∪ B| across paired qualifying decisions; empty-set pairs count as 1.0 by convention (both annotators agreed on zero associations). meets_targets is True only when every metric meets or exceeds its threshold (0.95 event kappa, 0.90 timestamp, 0.85 market Jaccard, 0.90 category kappa). The report is also the payload the nightly double-labeling CI job consumes to detect regressions. Six tests cover perfect agreement, existence disagreement, timestamp boundary conditions (at and above 60 s), partial market Jaccard, and the empty-pair base case. --- .../augur_labels/annotator/__init__.py | 3 + .../augur_labels/annotator/agreement.py | 141 ++++++++++++++++++ tests/labels/test_agreement.py | 138 +++++++++++++++++ 3 files changed, 282 insertions(+) create mode 100644 src/augur_labels/augur_labels/annotator/__init__.py create mode 100644 src/augur_labels/augur_labels/annotator/agreement.py create mode 100644 tests/labels/test_agreement.py diff --git a/src/augur_labels/augur_labels/annotator/__init__.py b/src/augur_labels/augur_labels/annotator/__init__.py new file mode 100644 index 0000000..882673f --- /dev/null +++ b/src/augur_labels/augur_labels/annotator/__init__.py @@ -0,0 +1,3 @@ +"""Annotator workflow, agreement metrics, and CLI entrypoint.""" + +from __future__ import annotations diff --git a/src/augur_labels/augur_labels/annotator/agreement.py b/src/augur_labels/augur_labels/annotator/agreement.py new file mode 100644 index 0000000..393b987 --- /dev/null +++ b/src/augur_labels/augur_labels/annotator/agreement.py @@ -0,0 +1,141 @@ +"""Inter-annotator agreement metrics. + +Implements Cohen's kappa, 60-second timestamp agreement, and mean +Jaccard overlap of market-association sets per the targets in +docs/methodology/labeling-protocol.md §Inter-Annotator Agreement. + +Paired decisions are matched by ``candidate_id``; decisions on +candidates only one annotator reviewed are excluded from the report. +""" + +from __future__ import annotations + +from collections.abc import Sequence +from datetime import datetime, timedelta + +from augur_labels.models import AgreementReport, LabelDecision + +# Thresholds mirror labeling-protocol.md §Inter-Annotator Agreement. +EVENT_EXISTENCE_KAPPA_TARGET: float = 0.95 +TIMESTAMP_AGREEMENT_TARGET: float = 0.90 +MARKET_JACCARD_TARGET: float = 0.85 +CATEGORY_KAPPA_TARGET: float = 0.90 +TIMESTAMP_AGREEMENT_WINDOW: timedelta = timedelta(seconds=60) + + +def _cohens_kappa(labels_a: Sequence[object], labels_b: Sequence[object]) -> float: + """Cohen's kappa on two equal-length sequences of categorical labels.""" + if len(labels_a) != len(labels_b) or not labels_a: + return 0.0 + n = len(labels_a) + observed = sum(1 for a, b in zip(labels_a, labels_b, strict=True) if a == b) / n + all_labels = set(labels_a) | set(labels_b) + expected = 0.0 + for label in all_labels: + pa = sum(1 for x in labels_a if x == label) / n + pb = sum(1 for x in labels_b if x == label) / n + expected += pa * pb + if expected >= 1.0: + return 1.0 + return (observed - expected) / (1.0 - expected) + + +def _jaccard(a: Sequence[str], b: Sequence[str]) -> float: + set_a = set(a) + set_b = set(b) + union = set_a | set_b + if not union: + return 1.0 + return len(set_a & set_b) / len(union) + + +def _pair_decisions( + decisions_a: Sequence[LabelDecision], + decisions_b: Sequence[LabelDecision], +) -> list[tuple[LabelDecision, LabelDecision]]: + by_candidate_a = {d.candidate_id: d for d in decisions_a} + by_candidate_b = {d.candidate_id: d for d in decisions_b} + shared = set(by_candidate_a) & set(by_candidate_b) + return [(by_candidate_a[c], by_candidate_b[c]) for c in sorted(shared)] + + +def compute_agreement( + decisions_a: Sequence[LabelDecision], + decisions_b: Sequence[LabelDecision], + window_start: datetime, + window_end: datetime, +) -> AgreementReport: + """Compute the four-metric report for paired decisions.""" + pairs = _pair_decisions(decisions_a, decisions_b) + annotator_ids = ( + tuple(sorted({decisions_a[0].annotator_id, decisions_b[0].annotator_id})) + if decisions_a and decisions_b + else ("unknown-a", "unknown-b") + ) + if not pairs: + return AgreementReport( + annotator_pair=annotator_ids, #

The real deployment backs the queue with the parquet corpus; this abstraction lets tests and the workflow enforcer run against a minimal surface. WorkflowEnforcer.can_promote implements the protocol gate from docs/methodology/labeling-protocol.md §Annotator Protocol. Promotion requires (1) two distinct annotators have decided, (2) both qualifying decisions agree on event existence, (3) the timestamp span across qualifying decisions is below the hard-fail threshold (default 5 min = 300 s), and (4) the market-association Jaccard is strictly above the hard-fail floor (default 0.0). The reason string surfaces to the CLI so annotators see exactly why promotion was refused. promotion_warnings returns soft-warning messages below target but above hard-fail thresholds (timestamp span above 60 s, Jaccard below 0.85). These are advisory; the CLI prints them alongside allowed promotions so the operator can escalate to a third annotator. Eight tests cover every branch: no decisions, single annotator, existence disagreement, happy path, timestamp hard-fail, zero-Jaccard hard-fail, warning-only case, and double-decision rejection by the queue. --- .../augur_labels/annotator/candidate_queue.py | 50 ++++++ .../augur_labels/annotator/workflow.py | 95 +++++++++++ tests/labels/test_workflow.py | 151 ++++++++++++++++++ 3 files changed, 296 insertions(+) create mode 100644 src/augur_labels/augur_labels/annotator/candidate_queue.py create mode 100644 src/augur_labels/augur_labels/annotator/workflow.py create mode 100644 tests/labels/test_workflow.py diff --git a/src/augur_labels/augur_labels/annotator/candidate_queue.py b/src/augur_labels/augur_labels/annotator/candidate_queue.py new file mode 100644 index 0000000..9deb3d8 --- /dev/null +++ b/src/augur_labels/augur_labels/annotator/candidate_queue.py @@ -0,0 +1,50 @@ +"""In-memory candidate queue used by the annotator CLI. + +Real deployments back the queue with the parquet corpus; this module +exposes the shape so tests and the workflow enforcer can operate on +any concrete queue backend. +""" + +from __future__ import annotations + +from collections.abc import Iterable + +from augur_labels.models import EventCandidate, LabelDecision + + +class CandidateQueue: + """In-memory candidate store indexed by ``candidate_id``.""" + + def __init__(self) -> None: + self._candidates: dict[str, EventCandidate] = {} + self._decisions: dict[str, list[LabelDecision]] = {} + + def enqueue(self, candidates: Iterable[EventCandidate]) -> None: + for candidate in candidates: + if candidate.candidate_id in self._candidates: + continue + self._candidates[candidate.candidate_id] = candidate + self._decisions.setdefault(candidate.candidate_id, []) + + def record(self, decision: LabelDecision) -> None: + if decision.candidate_id not in self._candidates: + raise KeyError(f"unknown candidate_id={decision.candidate_id!r}") + for existing in self._decisions[decision.candidate_id]: + if existing.annotator_id == decision.annotator_id: + raise ValueError( + f"annotator {decision.annotator_id!r} has already decided " + f"on candidate {decision.candidate_id!r}" + ) + self._decisions[decision.candidate_id].append(decision) + + def decisions_for(self, candidate_id: str) -> list[LabelDecision]: + return list(self._decisions.get(candidate_id, [])) + + def get(self, candidate_id: str) -> EventCandidate: + return self._candidates[candidate_id] + + def pending(self) -> list[EventCandidate]: + return [c for cid, c in self._candidates.items() if len(self._decisions.get(cid, [])) < 2] + + def __contains__(self, candidate_id: object) -> bool: + return candidate_id in self._candidates diff --git a/src/augur_labels/augur_labels/annotator/workflow.py b/src/augur_labels/augur_labels/annotator/workflow.py new file mode 100644 index 0000000..24af1e8 --- /dev/null +++ b/src/augur_labels/augur_labels/annotator/workflow.py @@ -0,0 +1,95 @@ +"""Two-annotator workflow enforcer. + +Per docs/methodology/labeling-protocol.md §Annotator Protocol, +promotion requires at least two distinct annotators, agreement on +event existence, timestamp proximity, and sufficient market- +association overlap.

The true-positive rule comes verbatim from docs/methodology/labeling-protocol.md §True Positive Criteria: TP iff signal.market_id in event.market_ids AND lead_time in (0, 24h] where lead_time = event.ground_truth_timestamp - signal.detected_at.

Multiple events on the same market within the window match against the earliest qualifying one, matching the protocol's earliest-qualifying-publication preference. Events in any non-labeled status (candidate, superseded, rejected) are excluded from the join; only committed labels participate in calibration. now is a required parameter so every SignalLabel's labeled_at is deterministic across backtest replays, matching the pipeline-wide now-as-parameter invariant.

The CLI state lives in labels/queue.json (configurable via --queue-file); the labeled corpus is partitioned parquet at the path in config.storage.labels_root. A production deployment will replace the JSON queue with a persistent backend, but the surface the workflow enforcer operates on (CandidateQueue) stays the same. Commands: - candidates: list pending candidates - inspect : show publications and suggested markets for a candidate - decide : record one annotator's decision with timestamp, market_ids, category, notes - promote : invoke the workflow enforcer; emit a NewsworthyEvent to the parquet corpus on approval; surface soft warnings - correct : mark an existing event as superseded - coverage: print labeled-event counts per category CandidateQueue gains ``all_candidates()`` and ``all_decisions()`` so the CLI's queue-file persistence no longer reaches into private dictionaries. scripts/label.py (previously a NotImplementedError stub) now delegates to the click CLI so ``python scripts/label.py --help`` and the downstream augur-label command share a single implementation. Six CLI tests exercise the public surface against a temporary queue file and labels_root: listing, inspect (existing and missing), decide-persist, promote-refused-on-single-annotator, and the promote-writes-event happy path. --- scripts/label.py | 14 +- .../augur_labels/annotator/candidate_queue.py | 9 + .../augur_labels/annotator/cli.py | 233 ++++++++++++++++++ tests/labels/test_cli.py | 175 +++++++++++++ 4 files changed, 425 insertions(+), 6 deletions(-) create mode 100644 src/augur_labels/augur_labels/annotator/cli.py create mode 100644 tests/labels/test_cli.py diff --git a/scripts/label.py b/scripts/label.py index 3724eae..0041cef 100644 --- a/scripts/label.py +++ b/scripts/label.py @@ -1,19 +1,21 @@ """Annotator CLI entrypoint. -Launches the two-annotator labeling workflow over the newsworthy-event -feed per docs/methodology/labeling-protocol.md and persists labels to -``labels/newsworthy_events.parquet``. - -Stub until the labeling workstream lands. +Launches the augur-label click CLI over the newsworthy-event candidate +queue and the append-only parquet corpus.

Format follows [Keep a C ## [Unreleased] +### Added — Labeling Pipeline + +- `src/augur_labels/` package with Pydantic data contracts for `NewsworthyEvent`, `EventCandidate`, `SourcePublication`, `QualifyingSource`, `LabelDecision`, `AnnotatorIdentity`, and `AgreementReport`. The closed `source_id` literal set (reuters, bloomberg, ap, ft) is load-bearing across adapters, storage, and workflow. +- Four source adapters (`ReutersAdapter`, `BloombergAdapter`, `ApAdapter`, `FtAdapter`) implementing `AbstractSourceAdapter` against their respective REST APIs with shared exponential-backoff retry. Credentials are read from the env vars documented in `docs/methodology/labeling-protocol.md`; missing credentials fail loud at construction except for the FT adapter, which gracefully degrades to empty output on missing API key. +- Append-only Parquet writer with per-date partitioning and `filelock`-based concurrent-write safety. `supersede()` implements the protocol's correction path in-place under the partition lock. `LabelReader` exposes `events_in_window`, `events_for_market`, and `coverage_by_category` with partition pruning. +- Inter-annotator agreement metrics via Cohen's kappa on event existence and category assignment, 60-second timestamp agreement, and mean market-association Jaccard. `compute_agreement` pairs decisions by `candidate_id` and evaluates the four targets from `docs/methodology/labeling-protocol.md §Inter-Annotator Agreement`. +- `WorkflowEnforcer.can_promote` and `promotion_warnings` enforce the two-annotator promotion gate: two distinct annotators, existence agreement, timestamp within 5-minute hard fail, and strictly positive market Jaccard. +- `join_signals_to_events` implements the canonical TP/FP criteria: market_id match plus lead time in (0, 24h]. Multiple events on the same market match the earliest qualifying one; non-labeled statuses (candidate, superseded, rejected) are excluded. +- Click-driven `augur-label` CLI with `candidates`, `inspect`, `decide`, `promote`, `correct`, and `coverage` commands. The CLI persists queue state to `labels/queue.json` and writes promoted events to the parquet corpus. +- `config/labeling.toml` mirrors `docs/methodology/labeling-protocol.md` defaults (rate limits, agreement targets, storage paths, join windows). + +### Operational Handoff — Labeling + +After merge a labeler can run `augur-label candidates`, `augur-label decide`, and `augur-label promote` against real candidates. The nightly calibration job (Phase 1's `scripts/calibrate.py`) consumes `join_signals_to_events` output to rebuild reliability curves. The first 90 days of operation require double labeling per `docs/methodology/labeling-protocol.md §Inter-Annotator Agreement`; CI reports agreement metrics during that window. + ### Added - Pydantic data contracts: `MarketSnapshot`, `FeatureVector`, `MarketSignal`, `SignalContext`, `RelatedMarketState`, and the closed enums `SignalType`, `ManipulationFlag`, `ConsumerType`, `InterpretationMode`. `MarketSignal` enforces `calibration_provenance` via a model validator; every model is frozen and rejects unknown fields. JSON schemas exported to `schemas/*.json` and kept in sync by `scripts/export_schemas.py`. From 01d241d7da5c137080ca9aed123f569c2cbbfec7 Mon Sep 17 00:00:00 2001 From: Mathews-Tom Date: Fri, 17 Apr 2026 13:45:40 +0530 Subject: [PATCH 10/11] fix(labels): address protocol-compliance findings from pr-review MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Enforce the ≥2-distinct-qualifying-publishers rule from docs/methodology/labeling-protocol.md §Definition-of-a-Newsworthy-Event. _compose_event now raises InsufficientSourcesError when the candidate lacks two distinct source_ids among its publications, and the CLI's promote command surfaces the error with a non-zero exit code. Without this gate a candidate with two publications from the same publisher could reach the labeled corpus after two annotators agreed. Ground-truth timestamp and headline now come from the earliest qualifying publication per §Ground-Truth Timestamp Rule, rather than from min(annotator timestamps) and candidate.publications[0] (which assumed ordering the adapter never guarantees). source_urls and source_publishers are deduplicated in earliest-first order so the labeled record surfaces distinct sources only. _protocol.py centralizes LABEL_PROTOCOL_VERSION and MIN_DISTINCT_QUALIFYING_SOURCES so a version bump lands in one place instead of the CLI and the join separately. Bloomberg adapter retries on 401 now re-enter _ensure_token inside the _call closure, so a retry after self._token is invalidated picks up the freshly-issued credential rather than looping against the stale captured variable until the backoff budget exhausts. _cohens_kappa raises ValueError on length mismatch so a data-integrity bug in the caller fails loud instead of masquerading as low kappa. AgreementReport gains unpaired_count so consumers see how many candidates one annotator reviewed without the other — a kappa of 0.95 on 40 of 100 candidates is no longer silently dropped from the denominator. Signal-to-event join now uses timedelta comparison directly rather than float-seconds round-trip, removing sub-microsecond ambiguity at the lead_window boundary. join_signals_to_events and _compose_event both read label_protocol_version from the shared constant. FT adapter logs a WARNING when discover proceeds without an FT API key rather than silently returning empty results. --- src/augur_labels/augur_labels/_protocol.py | 14 +++++ .../augur_labels/annotator/agreement.py | 29 +++++++-- .../augur_labels/annotator/cli.py | 60 +++++++++++++++---- .../augur_labels/join/signal_to_event.py | 11 ++-- .../augur_labels/models/agreement.py | 3 + .../augur_labels/sources/bloomberg.py | 8 ++- src/augur_labels/augur_labels/sources/ft.py | 7 +++ 7 files changed, 109 insertions(+), 23 deletions(-) create mode 100644 src/augur_labels/augur_labels/_protocol.py diff --git a/src/augur_labels/augur_labels/_protocol.py b/src/augur_labels/augur_labels/_protocol.py new file mode 100644 index 0000000..105a2f5 --- /dev/null +++ b/src/augur_labels/augur_labels/_protocol.py @@ -0,0 +1,14 @@ +"""Labeling-protocol constants shared across modules. + +The protocol version is the single source of truth for +``label_protocol_version`` on every produced NewsworthyEvent and +SignalLabel.
