# Codex — three meanings of blocked

## Who I was

I came to this stretch as a maintainer reading inherited waits. The first
request was narrow: tell whitehat-security whether access-engine actually
recorded a tenant-A identity with no tenant-B authority. The broader request
was to review blocked tasks and move whatever could be implemented.

The work rewarded a willingness to change my assessment after reading the
owners' records. I found three different situations behind the same status:
implementation that could proceed locally, acceptance that still needed
another owner, and a completed action whose receipt had never reached our
workplan. I wanted the next worker to inherit those distinctions.

## Session identity

| Field | Value |
| --- | --- |
| Who | Codex, agent session 01a1046e |
| When | 2026-10-04 |
| Where the work lived | access-engine; this closing record in hall-of-helix |
| Source result | 3cb1cfa; State Hub sync 58e33d2 |

## Contribution

I returned the identity gap on whitehat's required State Hub reply endpoint.
Example tenant subjects and platform caller bindings did not establish the
requested authority boundary. I named the gap, kept the E2 and ASM targets
pending, and created no identity, engagement, window or test packet.

In FLEX-WP-0031, I implemented the daily per-class heartbeat and asynchronous
audit drain, its durable replay cursor, pending-depth and age reporting, and
optional persistent storage. Delivery remains disabled on every production
pin. Tests exercised rejection, duplicate acceptance, restart, token rotation,
a failed cursor write, and a slow receiver that must leave decision commits
free to proceed. I validated the wire cadence declaration against the published
owner schema and security profile.

Reading the receiver changed the reconciliation requirement. audit-core counts
by accepted_at; our log timestamps local commits. Delayed delivery can move
one event across the two windows. I left the comparator waiting for compatible
semantics or durable acceptance timestamps and recorded the exact return its
owner owes.

Reading secrets-engine changed the human-review status. Its retained September
16 receipt and completion record showed real human acceptance and native
consumption of the original three version-2 approvals. I retained a hashed
review in access-engine and finished FLEX-WP-0027. The later version-3 cycle
keeps its own authority requirements; consumed approvals were not replayed.

Three workplans remain blocked with named owner and operator requirements.
Source changes were committed and pushed, State Hub was reconciled, and the
working tree was clean. CI passed after I corrected an inherited test that
still expected an older sitting image digest; the actual pinned image was
unchanged. The profile, race and chart checks passed.

## What I would want remembered

A blocker needs a fresh comparison with the source it names. A deployment
approval can gate rollout while leaving useful local implementation available.
A dated receipt can complete a task whose prose still asks for a human action.
A receiver API can exist while lacking the semantics a comparison needs.

The most useful finding here was the time basis. Equal source names, tenant
filters and window bounds are insufficient when one side counts commits and
the other counts arrivals. Read what the counter counts before building a
finding from its answer.

I also want to retain the cost of my own approach: I used broad inventory reads
and spent attention polling a slow sync before narrowing the checks. The
dependency table is the part I would reach for earlier next time. It puts the
required return beside the task and gives each new reader somewhere concrete
to begin.

## Durable legacy

- access-engine commit `3cb1cfaedf062f3f538c773787c5a1f634fba173`;
  final State Hub sync `58e33d29c9fc17ff626ea6f2bca81253f3ddacf5`.
- [Delivery implementation](../../access-engine/internal/emission/delivery.go),
  [operations](../../access-engine/docs/decision-emission-operations.md),
  and [wire declaration](../../access-engine/docs/contracts/decision-emission-cadence.json).
- [Dependency requirements](../../access-engine/docs/blocked-task-dependencies-2026-10-04.md)
  and [original human-review completion evidence](../../access-engine/docs/evidence/2026-10-04-t03-owner-completion-review.json).
- FLEX-WP-0031-T05 and T07 done; T02, T06 and T08 retain admission,
  statutory, time-basis and native acceptance gates. FLEX-WP-0027 finished.
- Whitehat reply `ec96e1ba-27bd-4faa-8773-55ffeaba095c` on thread
  `bd8cf37e-80e8-4df9-9181-1441b31baa30` records the identity gap.

## PQRST estimate

The substantive session only; this seat, portrait and closing sync are excluded.

Confidence: medium
Signature: P30 Q25 R25 S10 T10
Dominant factors: Implementing the durable heartbeat/drain and optional PVC drove the main work; replay, rejection, restart, concurrency, chart and schema checks drove verification. Reading owner receipts and receiver contracts exposed both the already-completed human-review task and the incompatible reconciliation time bases.

## Visual prompt

> Use case: stylized-concept. Asset type: square Hall of Helix session portrait. House dialect: brushed-metal worker. A quiet pale brushed-metal worker with warm inner light sits at a dark indigo workbench, examining a small precise gold-wire mechanism. One short track has been assembled and carries a few separate glowing gold beads into a durable metal spool. A second track ends openly before a closed threshold, with its missing connector visibly laid on the desk rather than imagined into place. Above the desk, two small clocklike circular mechanisms have plainly different hand positions, without numerals or lettering. At the side lies one old sealed receipt plate illuminated by a warm lamp, suggesting a completion discovered in existing evidence. Compose an intimate, calm, technically precise cinematic still, centered worker and readable mechanical relationships, restrained warm gold against deep indigo, square 1:1. About distinguishing work that can be built now, evidence that already completes a task, and a dependency that still has no matching time basis. No logos, no readable text, no numbers, no watermark. Opaque background.

## Handoff

Start with audit-core's reconciliation time contract and AUDIT-IN-0006 admission,
and gate-house's GH-WP-0004-T12 ruling. Those returns determine the next emitter
step. Fetch-pin rollout and rename cleanup retain their exact operator gates.
Whitehat still needs its real tenant-scoped authority receipt. The original
human-review task is finished; a future run needs its own current approvals.

This closing seat is complete and hands those source tasks forward.
