"""Workflow-event and conversation timeline model (#637, Phase 1).
Operators cannot browse a unified timeline of workflow events, decisions,
tool calls, and handoffs: the evidence is scattered across control-plane
events, Gitea canonical handoff comments, and local logs. This module defines
one durable, versioned event schema and per-source adapters that normalise
those scattered records into a single ``WorkflowEvent`` stream, plus a
read-only query layer (filter by issue / PR / session, stable ordering,
pagination) that the ``/api/v1/timeline`` route serves.
Design rules honoured here:
- **Read-only.** Sources are read; nothing is mutated. The control-plane
database is opened through a ``mode=ro`` URI so a missing or unwritable DB
degrades to a reason instead of creating directories or running migrations.
- **Fail-soft per source.** An unavailable source degrades to a status with a
reason rather than raising, and a source that could not run is never
rendered as an empty-and-healthy timeline.
- **Answerable filters only.** Each source declares which filter dimensions it
can actually answer. A filter dimension no source that ran can carry is
refused with an explicit reason rather than silently matching nothing: an
empty page from an unanswerable filter reads to an operator as "no such
activity", which is a different — and false — statement.
- **Redaction at the boundary, fail closed.** Every free-text field (event
messages, redacted tool arguments, decision/proof text) is run through the
console redaction policy before it leaves this module, and *before* any
structured value is derived from it — evidence references are extracted from
redacted text, then independently revalidated before serialization. An
unredactable value becomes the placeholder, and a value that cannot be proven
safe is dropped — an unredacted payload is never emitted, and a generation
error never drops raw data to a caller or a log.
- **Stable ordering.** Events sort by ``(timestamp, source_rank, event_key)``
with a deterministic tiebreak, so pagination is stable across calls and
events with equal or missing timestamps keep a fixed order.
Non-goals (from the issue): no full chat replay, no mutation of historical
events, no unredacted tool-argument storage.
