AZ-943 implementation attempt confirmed the C++ binding cannot satisfy
AC-4 without upstream OKVIS2 patches. The spec's "approach (a)
in-binding subclass workaround" is structurally impossible:
- ThreadedSlam::estimator_ is `private` (not `protected`)
- ViSlamBackend has no public covariance / counts / parallax / MRE
accessor in the v2 upstream headers
- TrackingState carries only id / isKeyframe / TrackingQuality enum /
recognisedPlace / isFullGraphOptimising / currentKeyframeId — none
of the five tracking-stats fields the binding needs
Filed the spec-documented "approach (b)" fallback as two sibling
tickets, both linked Jira-side as `is blocked by` against AZ-943:
- AZ-951 (3 SP): upstream patch — expose 6x6 pose covariance accessor
(+ ADR-XXX for the AZ-332 Plan-phase pin deviation)
- AZ-952 (3 SP): upstream patch — expose tracking-stats accessor
(feature counts + parallax + MRE)
AZ-943 transitioned In Progress -> To Do in Jira, full audit comment
attached. Local AZ-943 spec moved todo/ -> backlog/ with PAUSED
preamble; original AC list preserved for the post-unblock turn.
Per user 2026-05-29 confirmation: cycle-4 Derkachi demo target stays
KLT/RANSAC (tests/e2e/replay/conftest.py line 159
c1_vio: strategy: klt_ransac), so AZ-951 + AZ-952 + AZ-943 chain is
correctly deferred. Pivoting next batch to AZ-897 (replay UI form).
Touches: _docs/02_tasks/_dependencies_table.md (preamble + table
rows for AZ-943 paused / AZ-951 / AZ-952 added; totals bumped to
142 product + 41 blackbox-test = 183, 448 product + 133 blackbox
= 581), _docs/_autodev_state.md (sub_step pivot to AZ-897).

Cycle 1 Product Implementation Completeness Gate post-mortem.
AZ-589 + AZ-590 were the wrong abstraction:
- AZ-589 targeted `okvis::ThreadedKFVio` (OKVIS v1 API) which does
not exist in the vendored OKVIS2 upstream; smartroboticslab/okvis2
exposes `okvis::ThreadedSlam` instead.
- AZ-590 assumed a "de-ROSified VINS-Mono pin" submodule exists;
`cpp/vins_mono/upstream/` has no `.gitmodules` entry.
- The actual production gap is the empty central
`_STRATEGY_REGISTRY`: `register_strategy(...)` is never called
outside test fixtures, so `compose_root()` raises
`StrategyNotLinkedError` for every component slug with a
strategy-selecting config field. Affects c1_vio + c2_vpr +
c2_5_rerank + c3_matcher + c3_5_adhop + c4_pose + c5_state.
Re-classification:
- AZ-589 + AZ-590 closed Won't Fix (Jira); spec files removed
from todo/ but rows retained in the dependencies table as
audit-trail.
- AZ-591 created (todo/, 5pt) — cross-cutting compose_root
per-binary bootstrap that populates `_STRATEGY_REGISTRY` for
the airborne binary. Scheduled as Batch 66 sole task.
- AZ-592 created (backlog/, 5pt placeholder) — AZ-332 Tier-2
validation bundle (real `okvis::ThreadedSlam` wiring + Linux CI
apt-install + DBoW2 vocab + Jetson). BLOCKED on Tier-2
prerequisites; honors AZ-332's `AZ-332_tier2_validation`
self-deferral handle.
- AZ-593 created (backlog/, 5pt placeholder) — AZ-333 Tier-2
validation bundle (de-ROSified VINS-Mono upstream + binding +
CI + Jetson). BLOCKED on upstream vendoring decision plus
Tier-2 prerequisites; honors AZ-333's parallel deferral pattern.
- AZ-332 + AZ-333 re-classified in cycle1 gate report from FAIL
to BLOCKED-on-Tier-2.
Step 7 stays in_progress until AZ-591 lands; after that it can
advance to Step 8 with AZ-592 + AZ-593 parked in backlog/.
