# SHR-WP-0002 — Predecessor generations and deployment reality

## The problem in one sentence

**Core Hub's production runtime — the generation-3 replacement, cut over
deliberately and correctly in July — serves from `hub.coulomb.social`, which
resolves to CoulombCore: the host being decommissioned.** No plan in any
repository accounts for that.

## Correction to this workplan's first draft

The first draft of `SHR-WP-0002` (2026-08-20, superseded before any task ran)
claimed generation 2 had "retired itself by attrition". **That was wrong**, and
the evidence contradicting it is in `core-hub`'s own archive:

- `CORE-WP-0005` finished **2026-07-03**: `hub.coulomb.social` ingress serves
  Core Hub; Inter-Hub compatibility, staging import, dual-run smokes, and
  production cutover gates all closed.
- `CORE-WP-0007` finished **2026-07-08**: Haskell/IHP infrastructure retired,
  the production Inter-Hub repo renamed/archived, `ihp-railiance-probe`
  archived — after *"a short post-cutover stabilization window"* and explicit
  operator approval to retire the Inter-Hub rollback deployment.

The `inter-hub` Deployment scaled `0/0` on railiance01 is that **rollback
deployment**, held at zero exactly as the workplan describes. It is not a
lapse; it is the designed end state of a careful retirement.

The lesson is the opposite of the one first drafted: **generation 2 was retired
well.** What nobody checked was whether the successor's runtime was standing on
durable ground.

## Re-baseline — 2026-09-04

The immediate runtime risk has been resolved. `CORE-WP-0011` moved Core Hub to
railiance01, its tasks are complete, and the project decision record documents
the corrected generation-2 history and the CoulombCore exit. The project must
still finish the cross-generation inventory and guardrails: the generation-2
disposition file and repository-reality ledger do not yet exist, `G-GEN` has not
been adopted, and live legacy package/access references remain.

## What was observed, 2026-08-20

| Generation | Position | Observed |
| --- | --- | --- |
| 1 — `state-hub` | Being retired by this project, under gates | Running; what the estate uses hourly |
| 2 — `inter-hub` | Retired `CORE-WP-0005`/`0007`, Jul 2026 | Correctly gone. Rollback deployment at `0/0` as designed |
| 3 — `core-hub` | The replacement, in production since 2026-07-03 | `hub.coulomb.social` → `92.205.130.254` = **CoulombCore**. No core-hub namespace or Deployment on railiance01 |
| — `hub-core` | The surviving repository (GOAL §1) | A reusable Python package, not a running service |

Three consequences, none recorded anywhere:

1. **The gen-1 retirement is being planned onto a runtime that has no home.**
   `G-HUB-RUNTIME` and `G-CORE-ABSORB` presume somewhere to absorb traffic into.
   That somewhere is currently a host with a decommission date, and the gate
   model does not represent that date at all.
2. **`core-hub/SCOPE.md` is stale in a way that hides this.** It still places
   "retiring production Inter-Hub before migration and smoke evidence exists"
   out of scope and lists `/api/v2` compatibility and "cutover planning from
   Inter-Hub" as in scope — work its own archive shows finished in July. A
   reader cannot tell from the live documents that the cutover already happened.
3. **`inventory/capabilities.yaml` does not mention `inter-hub`.** The migration
   was real, so this is a smaller gap than first thought — but `G-DISP` still
   has no record of where gen-2 capabilities went, and the estate cannot
   currently answer "does anything still provide the unified operator surface?"
   without reading an archived workplan.

## Why this belongs to the project and not to a child repo

No single repository can see it. `core-hub` knows its own migration plan;
`llm-connect` knows its consumers; `ops-warden` knows its access lanes. Only this
project holds the cross-repository authority, the disposition inventory, and the
gates — and `G-DISP` ("full disposition inventory"), `G-CORE-ABSORB` and
`G-HUB-RUNTIME` are all currently gated on assumptions that the observations
above contradict.

Per `SCOPE.md`, this workplan **decides and inventories; it does not implement**.
Every implementation task it identifies is routed to the owning repository by
identifier.

## Tasks

```task
id: SHR-WP-0002-T01
status: done
priority: high
state_hub_task_id: "8c54ea9b-8a92-55bc-80ce-8425678f3efe"
```

**Done 2026-08-20 — there was a proper cutover.** `CORE-WP-0005` closed the
production cutover gates on 2026-07-03; `CORE-WP-0007` retired the Haskell/IHP
infrastructure by 2026-07-08 with operator approval and a stabilization window.
The `0/0` rollback deployment is the designed end state.

**Completed 2026-09-04.** `DECISIONS.md` records the correction and its evidence,
so the project's own record shows that the first reading was wrong and why.

```task
id: SHR-WP-0002-T02
status: todo
priority: high
state_hub_task_id: "fdae9c55-5a85-5b11-91ed-0b724129d887"
```

**Extend the disposition inventory backwards to generation 2.** Smaller than
first thought — the migration was real — but still unrecorded here. `G-DISP` demands
that every capability reach an explicit destination or retirement decision.
Applied only to State Hub, it lets gen-2 capabilities vanish unrecorded.

Produce `inventory/inter-hub-disposition.yaml` in the shape of the existing
capability rollup: for each capability gen 2 was to provide — domain hubs, shared
manifests, widgets, registries, events, unified operator surface — record whether
it is **served today** (and by what), **planned** (and by whom, under which
workplan), or **dropped** (and by whose decision).

The expected output is uncomfortable and worth having: a list of things the
estate intended to have, does not have, and has not decided to do without.

```task
id: SHR-WP-0002-T03
status: done
priority: high
state_hub_task_id: "06119690-312f-5d14-aee0-2fc4dac1e89e"
```

**This is now the workplan's centre of gravity: get the gen-3 runtime off
CoulombCore.** `G-HUB-RUNTIME` and `G-CORE-ABSORB` presume a runtime to absorb
traffic into. That runtime is `hub.coulomb.social` on CoulombCore — production
since 2026-07-03 — plus a `core-hub-staging` tunnel to the same host. There is
no core-hub presence on railiance01, and `hub-core` is a package, not a service.

Decide and record: does core-hub's runtime move to railiance01 first, or does
consolidation into `hub-core` (GOAL §1) happen directly, skipping a migration to
a host that is itself scheduled to disappear? Sequence it explicitly **against
the CoulombCore decommission date**, which is the real constraint and is not
currently represented in the gate model.

Precedent worth reusing: `issue-core` was migrated off CoulombCore on 2026-08-19
via `ISSUE-WP-0007` and a `rapp-issue-core` package. That is the pattern, and it
is one week old.

**Routed to `core-hub` 2026-08-20; waiting on their answer.** The vehicle is
`CORE-WP-0010` (runtime absorption into hub-core, `proposed`, all tasks `todo`),
which depends on `HUB-WP-0004` — itself `proposed`, and still carrying an open
decision about whether `hub-core` stays an importable library or becomes a
library plus a permanent thin host.

**So the chain that would move production off CoulombCore bottoms out in an
unanswered architecture question.** That is a sequencing problem rather than an
implementation one, which is why it sits here and not in a child repo — but the
answer is core-hub's.

Two shapes were put to them:

- **(a) Interim move** — package Core Hub as-is onto railiance01, absorb into
  hub-core later on a calm schedule. Costs a migration that would otherwise not
  happen; buys independence from the decommission date.
- **(b) Absorb directly** — skip the interim host and let `CORE-WP-0010` /
  `HUB-WP-0004` be the migration. Cheaper in total work; couples production
  continuity to finishing an architecture decision under a hard external
  deadline.

The project does not choose between them, but records the reasoning either way.
The one position taken: **leaving it implicit is not acceptable**, because the
decommission date is a real constraint currently represented in no plan —
including this project's own gate model, which `T06` addresses.

Also asked: whether the decommission date changes `HUB-WP-0004`'s open
library-vs-thin-host decision. **Pinned 2026-08-20 by the operator: CoulombCore retires by 2026-08-31.**
Eleven days. See `DECISIONS.md`. On that constraint the project recommends the
interim move — an architecture decision plus a production migration inside
eleven days is not a plan. The choice remains core-hub's.

**Completed 2026-09-04.** Core Hub chose and completed the interim move under
`CORE-WP-0011`. Production now runs on railiance01, the CoulombCore Deployments
were scaled to zero after stabilization, and the sequence and disposition are
recorded in `DECISIONS.md`. `CORE-WP-0010` remains historical context, not the
vehicle that ultimately resolved this task.

```task
id: SHR-WP-0002-T04
status: todo
priority: medium
state_hub_task_id: "3815d764-b484-5342-9c7d-2edacc02be13"
```

**Reconcile stated scope against reality across participating repositories.**
The lineage confusion is visible in the documents: `core-hub/SCOPE.md` guards a
predecessor that is not running; `llm-connect/SCOPE.md` names a consumer
relationship that cannot exist; `ops-hub` describes itself as an extension *for
Core Hub*, a repository this project intends to retire into `hub-core`.

Produce a table of every participating repository's stated position versus
observed reality, and route each correction to its owner. Do **not** edit their
files from here — the project's authority is the ledger, not the prose.

```task
id: SHR-WP-0002-T05
status: progress
priority: medium
state_hub_task_id: "c2957182-4bb3-5aa9-9940-656956cfe52d"
```

**Sweep the downstream lanes that outlived their subject.** A retired generation
leaves access and credential lanes behind, and they do not expire on their own.

Known instance: ops-warden's routing catalog carries `inter-hub-bootstrap-ssh` —
`status: active`, `risk: high`, last reviewed 2026-06-24 — a bootstrap SSH
envelope for a system that runs nowhere, whose runbook points at "the ops-hub
production activation lane tracked by `CUST-WP-0049`". ops-warden cannot retire
it alone: the lane may still serve ops-hub activation independently of inter-hub's
runtime, and only this project can see both sides.

Ask each participating repository for lanes, tunnels, credentials and scheduled
jobs whose subject is a retired or lapsed generation. Route retirements to owners;
record the sweep here so the next generation change has a checklist rather than a
memory.

**Progress 2026-09-04.** The sweep has enumerated SSH, registry, credential, and
runner lanes, but closure is incomplete. In particular,
`inter-hub-bootstrap-ssh` remains an active high-risk catalog lane and needs an
owner decision rather than silent deletion.

```task
id: SHR-WP-0002-T06
status: todo
priority: medium
state_hub_task_id: "714ce904-bccd-5cd8-ae2e-a756f5c0bccc"
```

**Add a generation-transition gate, so this cannot recur.** The project has gates
for retiring State Hub deliberately. It has none that would have caught a
predecessor lapsing, or a successor running only on a host scheduled for
shutdown.

Propose `G-GEN` for `architecture/retirement-gates_v0.1.md`: no generation is
considered superseded until its capabilities carry explicit dispositions, its
consumers are reconciled, its downstream lanes are swept, and its successor is
deployed somewhere that will still exist. Take it through the project's normal
decision route rather than adding it unilaterally.

```task
id: SHR-WP-0002-T07
status: progress
priority: high
state_hub_task_id: "a89cf85d-d613-5434-92cb-11f850889b08"
```

**The registry dependency, found 2026-08-20 and not previously tracked.**
`gitea.coulomb.social` is a live container registry on CoulombCore, and two
railiance01 workloads pull images from it:
`reuse/Deployment/reuse-surface` and `state-hub/Job/state-hub-alembic-init`
(checked across Deployments, StatefulSets, DaemonSets, Jobs and CronJobs — that
is the complete set).

Nothing breaks on decommission day, because running pods already hold their
images. It breaks at the next restart, reschedule or scale-up, as
`ImagePullBackOff`.

**Progress update 2026-09-04.** `REUSE-WP-0020` and `KAIZEN-WP-0010` are
finished, and Core Hub has moved. Closure is still blocked by live legacy
surfaces: the `whynot-design-npm-publish` lane targets the old npm registry,
`issue-core` retains its legacy Gitea PyPI upload target, and the platform ArgoCD
bootstrap allow-list still admits Gitea repositories. Route and verify those
residuals before marking this task done.

**The two are not equally urgent** (corrected 2026-08-20 after checking each
reference's liveness):

- **`reuse-surface` — worse than stale: a live runtime dependency.** A running
  Deployment on the old registry, pinned to a 2026-07-07 commit and **22 commits
  behind** main. Its CI switched to forgejo three hours after that commit and has
  published there ever since; the deployment was never repointed.

  **Escalated 2026-08-20.** At the deployed commit,
  `registry/federation/sources.yaml` points at `gitea.coulomb.social` for **50 of
  its 61 sources** (all 61 are forgejo at HEAD — migrated in `d1c1313`,
  `RAIL-HO-WP-0006`). So production is not merely running an old image: it is
  **actively federating from the host being switched off**, and that breaks *on
  2026-08-31 with no restart required*. This is a different and worse failure
  mode than the `ImagePullBackOff` risk it was first filed under.

  It also inverts the conservative option. Rebuilding the pinned commit onto
  forgejo — the apparently low-risk choice — does **not** fix federation, because
  the gitea URLs are in the code at that commit. Deploying HEAD is the smaller
  intervention once the runtime dependency is counted.

  Side finding for that repo: `REUSE-WP-0019` is archived as finished and records
  a production deploy of its T01/T02 work, but T04–T06 (telemetry store,
  aggregation, **hub freshness monitoring**) landed after the deployed commit and
  appear never to have shipped. A workplan closed as done contains a
  freshness-monitoring feature production does not have.
- **`state-hub` — mostly a false alarm.** The Deployment is already on
  `forgejo.coulomb.social/coulomb/state-hub:main-d8808bf`. The gitea reference is
  a *completed* one-shot Job that will not re-run by itself; the residual risk is
  a chart template recreating it. Worth cleaning, not urgent.

There was **no repository rename**. This is a registry migration (gitea →
forgejo, early July) in which producers moved and some consumers did not.

### Full sweep, 2026-08-20 — CoulombCore runs *two* registry services

The first pass looked at container images. `gitea.coulomb.social` also serves a
**PyPI package index** (`/api/packages/coulomb/pypi`), confirmed by
`railiance-fabric/fabric/interfaces/railiance-forge-python-package-index.yaml`.
Both die on 2026-08-31.

Sweeping every repo for `gitea.coulomb.social` in operational files (yaml, sh,
py, Makefile, Dockerfile, toml, json) and classifying by whether anything can
still act on it:

**Live, must move before 2026-08-31**

| Reference | What breaks |
| --- | --- |
| `reuse-surface` Deployment image | Next restart → `ImagePullBackOff`. Also 22 commits stale |
| ~~`kaizen-agentic` Makefile + README + 5 docs~~ | **DONE 2026-08-20** (`KAIZEN-WP-0010`, finished). Forgejo serves 1.4.0 anonymously (wheel + sdist); fresh venv installed 1.4.0 with `--no-cache-dir` from the documented forgejo extra index, CLI and import both reported 1.4.0. Gitea Make variables/target, consumer URLs, CLI links, release metadata and the `.gitea` issue-template path retired; historical workplans and changelog left truthful. Tests and `make release-check` pass |

**Live but already dual-pathed — retire the old half**

| Reference | Note |
| --- | --- |
| `issue-core/Makefile:240` publishes to gitea PyPI | Line 250 already publishes to forgejo. The gitea target is legacy and should go |

**Owned by the thing being decommissioned — expected**

`railiance-forge` (`manifests/gitea-ingress.yaml`, `helm/gitea-registry-values.yaml`,
`tools/gitea-runner-status.sh`) owns gitea itself; these retire *with* it.

**Not live — leave alone**

Tests asserting historical facts (`railiance-fabric`, `markitect-main`,
`reuse-surface/tests/test_forge_host.py`, `railiance-platform/tests/…`),
inventory snapshots and asset/data registers (`disaster-control`,
`domain-tree`, `railiance-fabric` snapshots), agent session blobs, and
`issue-core/Dockerfile:5` (a comment). These *record* that gitea existed, which
stays true after it is switched off. Rewriting them would destroy history to
tidy a grep.

**One to check, not ours:** `railiance-platform/argocd/bootstrap/01-railiance-tenants-project.yaml:14`
permits `sourceRepos: https://gitea.coulomb.social/coulomb/*.git`. railiance01
has no ArgoCD `applications` resource type, so this appears inert — but it is a
bootstrap file and should be confirmed rather than assumed.

### Credential-lane sweep, 2026-08-20 — a *third* registry service

Checking ops-warden's routing catalog found what the file sweep could not: the
host serves **three** package services, not two.

`gitea.coulomb.social/api/packages/coulomb/npm/` is an **npm registry**, and
ops-warden's catalog lane `whynot-design-npm-publish` — `risk: high`,
production-exercised (WP-0018 published `@whynot/design@0.4.0` through it) —
vends the `NPM_AUTH_TOKEN` that publishes to it.

So the complete CoulombCore package surface is:

| Service | Endpoint | Known consumers |
| --- | --- | --- |
| OCI container registry | `gitea.coulomb.social/coulomb/…` | `reuse-surface` (live Deployment) |
| PyPI index | `…/api/packages/coulomb/pypi` | `kaizen-agentic` (never migrated), `issue-core` (legacy half) |
| **npm registry** | `…/api/packages/coulomb/npm/` | `@whynot/design` via ops-warden lane `whynot-design-npm-publish` |

**Consequence for the credential lane:** after 2026-08-31 that lane routes to a
registry that does not exist. It does not fail safe — an operator following it
gets a token for a dead endpoint and debugs the token. `forgejo-admin-api-token`
already exists as the forgejo-side equivalent and its keywords include
`forgejo-npm`, so the destination is plausibly in place; ops-warden must confirm
rather than assume, and cannot repoint the lane before the packages are on
forgejo — the same publish-before-repoint rule as `KAIZEN-WP-0010`.

Routed to ops-warden (lane owner for the catalog entry; `railiance-platform`
owns the credential itself).

### CI runner sweep, 2026-08-20 — clear, and the sweep is now closed

86 repositories carry `.forgejo/workflows`, with jobs on `self-hosted` (83),
`container-build` (11), `ubuntu-latest` (87) and `docker` (1). Those labels
resolve to registered runners, so the question was where the runners live.

**The only runner in the estate is on railiance01**: `forgejo/forgejo-runner`,
a Deployment up 48 days, registering against `${FORGEJO_INSTANCE}` — forgejo,
not gitea. No runner exists on CoulombCore.

`railiance-forge/tools/gitea-runner-status.sh`, which prompted this check, is a
**legacy artifact**: it defaults to `RUNNER_HOST=haskelseed` and probes
`INTER_HUB_IMAGE`. Both are already retired — haskelseed's bridge on 2026-08-19,
inter-hub in July. So the gitea-era runner lived on haskelseed and died with it a
day ago, and nothing broke: evidence in itself that gitea-based CI is no longer
in use.

**CoulombCore's dependency surface is therefore fully enumerated** across four
methods — tunnels, service DNS, workload image references, operational-file
grep, credential-lane catalog, and CI runners. Each method found something the
previous one structurally could not see, which is the finding `T06`'s `G-GEN`
gate should encode: **an inventory is only as complete as the number of
independent ways you looked.**

`forgejo.coulomb.social` is already on railiance01, so the work is retag, push,
update manifest. Routed to `railiance-platform`; ownership of the `reuse-surface`
manifest sits with that repo.

**Why this is a project task and not a platform ticket:** it was missed because
the decommission inventory was assembled from tunnels and workplans. A host is
not free of dependents because nothing tunnels to it. Feed that into `T06`'s
`G-GEN` gate — a generation or host transition must enumerate what *pulls,
resolves and authenticates* against the thing being switched off, not only what
connects to it.
