When automatic retries for stranded todo/in_progress work are exhausted,
create an explicit `stranded_issue_recovery` child issue assigned to an
invokable manager (reportsTo chain, then CTO/CEO, then the original
assignee). Link it as a first-class blocker on the source, wake the
recovery owner, and surface the next action in a source-issue comment
instead of leaving the work silently blocked.

## Thinking Path
> - Paperclip orchestrates AI agents for zero-human companies
> - Adapter execution and retry classification decide whether agent work
pauses, retries, or recovers automatically
> - Transient provider failures need to be classified precisely so
Paperclip does not convert retryable upstream conditions into false hard
failures
> - At the same time, operators need an up-to-date model list for
Codex-backed agents and prompts should nudge agents toward targeted
verification instead of repo-wide sweeps
> - This pull request tightens transient recovery classification for
Claude and Codex, updates the agent prompt guidance, and adds Codex
model refresh support end-to-end
> - The benefit is better automatic retry behavior plus fresher
operator-facing model configuration
## What Changed
- added Codex usage-limit retry-window parsing and Claude extra-usage
transient classification
- normalized the heartbeat transient-recovery contract across adapter
executions and heartbeat scheduling
- documented that deferred comment wakes only reopen completed issues
for human/comment-reopen interactions, while system follow-ups leave
closed work closed
- updated adapter-utils prompt guidance to prefer targeted verification
- added Codex model refresh support in the server route, registry,
shared types, and agent config form
- added adapter/server tests covering the new parsing, retry scheduling,
and model-refresh behavior
## Verification
- `pnpm exec vitest run --project @paperclipai/adapter-utils
packages/adapter-utils/src/server-utils.test.ts`
- `pnpm exec vitest run --project @paperclipai/adapter-claude-local
packages/adapters/claude-local/src/server/parse.test.ts`

server/src/__tests__/heartbeat-retry-scheduling.test.ts`
## Risks
- Moderate behavior risk: retry classification affects whether runs
auto-recover or block, so mistakes here could either suppress needed
retries or over-retry real failures
- Low workflow risk: deferred comment wake reopening is intentionally
scoped to human/comment-reopen interactions so system follow-ups do not
revive completed issues unexpectedly

## Thinking Path
> - Paperclip orchestrates AI agents for zero-human companies
> - Task references are a core part of how operators understand issue
relationships across the UI
> - Those references appear both in markdown bodies and in sidebar
relationship panels
> - The rendering had drifted between surfaces, and inline markdown
pills were reading awkwardly inside prose and lists
> - This pull request unifies the underlying issue-reference treatment,
routes issue descriptions through `MarkdownBody`, and switches inline
markdown references to a cleaner text-link presentation
> - The benefit is more consistent issue-reference UX with better
readability in markdown-heavy views
## What Changed
- unified sidebar and markdown issue-reference rendering around the
shared issue-reference components
- routed resting issue descriptions through `MarkdownBody` so
description previews inherit the richer issue-reference treatment
- replaced inline markdown pill chrome with a cleaner inline reference
presentation for prose contexts
- added and updated UI tests for `MarkdownBody` and `InlineEditor`
## Verification
- `pnpm exec vitest run --project @paperclipai/ui
ui/src/components/MarkdownBody.test.tsx
ui/src/components/InlineEditor.test.tsx`
## Risks
- Moderate UI risk: issue-reference rendering now differs intentionally
between inline markdown and relationship sidebars, so regressions would
show up as styling or hover-preview mismatches

## Thinking Path
> - Paperclip orchestrates AI agents for zero-human companies
> - Issue detail is where operators coordinate review, approvals, and
follow-up work with active runs
> - That thread UI needs to surface blockers, descendants, review
handoffs, and reply ergonomics clearly enough for humans to guide agent
work
> - Several small gaps in the issue-thread flow were making review and
navigation clunkier than necessary
> - This pull request improves the reply composer, descendant/blocker
presentation, interaction folding, and review-request handoff plumbing
together as one cohesive issue-thread workflow slice
> - The benefit is a cleaner operator review loop without changing the
broader task model
## What Changed
- restored and refined the floating reply composer behavior in the issue
thread
- folded expired confirmation interactions and improved post-submit
thread scrolling behavior
- surfaced descendant issue context and inline blocker/paused-assignee
notices on the issue detail view
- tightened large-board first paint behavior in `IssuesList`
- added loose review-request handoffs through the issue
execution-policy/update path and covered them with tests
## Verification

## Visual Evidence
- UI layout changes are covered by the focused issue-thread component
and issue-detail tests listed above. Browser screenshots were not
attachable from this automated greploop environment, so reviewers should
use the running preview for final visual confirmation.
## Risks
- Moderate UI-flow risk: these changes touch the issue detail experience
in multiple spots, so regressions would most likely show up as
thread-layout quirks or incorrect review-handoff behavior

## Thinking Path
> - Paperclip orchestrates AI agents for zero-human companies
> - Company skills are part of the control plane for distributing
reusable capabilities
> - Board flows that inspect company skill detail should stay responsive
because they are operator-facing control-plane reads
> - The existing detail path was doing broader work than needed for the
specific detail screen
> - This pull request narrows that company-skill detail loading path and
adds a regression test around it
> - The benefit is faster company skill detail reads without changing
the external API contract
## What Changed
- tightened the company-skill detail loading path in
`server/src/services/company-skills.ts`
- added `server/src/__tests__/company-skills-detail.test.ts` to verify
the detail route only pulls the required data
## Verification
- `pnpm exec vitest run --project @paperclipai/server
server/src/__tests__/company-skills-detail.test.ts`
## Risks
- Low risk: this only changes the company-skill detail query path, but
any missed assumption in the detail consumer would surface when loading
that screen

## Thinking Path
> - Paperclip orchestrates AI agents for zero-human companies
> - The environments subsystem already models execution environments,
but before this branch there was no end-to-end SSH-backed runtime path
for agents to actually run work against a remote box
> - That meant agents could be configured around environment concepts
without a reliable way to execute adapter sessions remotely, sync
workspace state, and preserve run context across supported adapters
> - We also need environment selection to participate in normal
Paperclip control-plane behavior: agent defaults, project/issue
selection, route validation, and environment probing
> - Because this capability is still experimental, the UI surface should
be easy to hide and easy to remove later without undoing the underlying
implementation
> - This pull request adds SSH environment execution support across the
runtime, adapters, routes, schema, and tests, then puts the visible
environment-management UI behind an experimental flag
> - The benefit is that we can validate real SSH-backed agent execution
now while keeping the user-facing controls safely gated until the
feature is ready to come out of experimentation
## What Changed
- Added SSH-backed execution target support in the shared adapter
runtime, including remote workspace preparation, skill/runtime asset
sync, remote session handling, and workspace restore behavior after
runs.
- Added SSH execution coverage for supported local adapters, plus remote
execution tests across Claude, Codex, Cursor, Gemini, OpenCode, and Pi.
- Added environment selection and environment-management backend support
needed for SSH execution, including route/service work, validation,
probing, and agent default environment persistence.
- Added CLI support for SSH environment lab verification and updated
related docs/tests.
- Added the `enableEnvironments` experimental flag and gated the
environment UI behind it on company settings, agent configuration, and
project configuration surfaces.
## Verification

ui/src/lib/new-agent-runtime-config.test.ts`
- `pnpm -r typecheck`
- `pnpm build`
- Manual verification on a branch-local dev server:
- enabled the experimental flag
- created an SSH environment
- created a Linux Claude agent using that environment
- confirmed a run executed on the Linux box and synced workspace changes
back
## Risks
- Medium: this touches runtime execution flow across multiple adapters,
so regressions would likely show up in remote session setup, workspace
sync, or environment selection precedence.
- The UI flag reduces exposure, but the underlying runtime and route
changes are still substantial and rely on migration correctness.
- The change set is broad across adapters, control-plane services,
migrations, and UI gating, so review should pay close attention to
environment-selection precedence and remote workspace lifecycle
behavior.
## Model Used
- OpenAI Codex via Paperclip's local Codex adapter, GPT-5-class coding
model with tool use and code execution in the local repo workspace. The
local adapter does not surface a more specific public model version
string in this branch workflow.

## Thinking Path
> - Paperclip orchestrates AI agents for zero-human companies.
> - This branch extends the issue control-plane so board operators can
pause, cancel, and later restore whole issue subtrees while keeping
descendant execution and wake behavior coherent.
> - That required new hold state in the database, shared contracts,
server routes/services, and issue detail UI controls so subtree actions
are durable and auditable instead of ad hoc.
> - While this branch was in flight, `master` advanced with new
environment lifecycle work, including a new `0065_environments`
migration.
> - Before opening the PR, this branch had to be rebased onto
`paperclipai/paperclip:master` without losing the existing
subtree-control work or leaving conflicting migration numbering behind.
> - This pull request rebases the subtree pause/cancel/restore feature
cleanly onto current `master`, renumbers the hold migration to
`0066_issue_tree_holds`, and preserves the full branch diff in a single
PR.
> - The benefit is that reviewers get one clean, mergeable PR for the
subtree-control feature instead of stale branch history with migration
conflicts.
## What Changed
- Added durable issue subtree hold data structures, shared
API/types/validators, server routes/services, and UI flows for subtree
pause, cancel, and restore operations.
- Added server and UI coverage for subtree previewing, hold
creation/release, dependency-aware scheduling under holds, and issue
detail subtree controls.
- Rebased the branch onto current `paperclipai/paperclip:master` and
renumbered the branch migration from `0065_issue_tree_holds` to
`0066_issue_tree_holds` so it no longer conflicts with upstream
`0065_environments`.
- Added a small follow-up commit that makes restore requests return `200
OK` explicitly while keeping pause/cancel hold creation at `201
Created`, and updated the route test to match that contract.
## Verification
- `pnpm --filter @paperclipai/db typecheck`
- `pnpm --filter @paperclipai/shared typecheck`
- `pnpm --filter @paperclipai/server typecheck`
- `pnpm --filter @paperclipai/ui typecheck`

src/__tests__/heartbeat-dependency-scheduling.test.ts`
- `cd ui && pnpm exec vitest run src/components/IssueChatThread.test.tsx
src/pages/IssueDetail.test.tsx`
## Risks
- This is a broad cross-layer change touching DB/schema, shared
contracts, server orchestration, and UI; regressions are most likely
around subtree status restoration or wake suppression/resume edge cases.
- The migration was renumbered during PR prep to avoid the new upstream
`0065_environments` conflict. Reviewers should confirm the final
`0066_issue_tree_holds` ordering is the only hold-related migration that
lands.
- The issue-tree restore endpoint now responds with `200` instead of
relying on implicit behavior, which is semantically better for a restore
operation but still changes an API detail that clients or tests could
have assumed.

## Thinking Path
> - Paperclip orchestrates AI agents; each agent runs under an adapter
that spawns a model CLI as a child process.
> - The pi-local adapter (`packages/adapters/pi-local`) spawns `pi` and
inherits the child's shell environment — including `PATH`, which
determines what the child's bash tool can execute by name.
> - Paperclip skills ship executable helpers under `<skill>/bin/` (e.g.
`paperclip-get-issue`) and Reviewer/QA-style `AGENTS.md` files invoke
them by name via the agent's bash tool.
> - Pi-local builds its runtime env with `ensurePathInEnv({
...process.env, ...env })` only — it never adds the installed skills'
`bin/` dirs to PATH. The pi CLI's `--skill` arg loads each skill's
SKILL.md but does not augment PATH.
> - Consequence: every bash invocation of a skill helper fails with
`exit 127: command not found`. The agent then spends its heartbeat
guessing (re-reading SKILL.md, trying `find`, inventing command paths)
and either times out or gives up.
> - This PR prepends each injected skill's `bin/` directory to the child
PATH immediately before runtimeEnv is constructed.
> - The benefit: pi_local agents whose AGENTS.md uses any `paperclip-*`
skill helper can actually run those helpers.
## What Changed
- `packages/adapters/pi-local/src/server/execute.ts`: compute
`skillBinDirs` from the already-resolved `piSkillEntries`, dedupe
against the existing PATH, prepend them to whichever of `PATH` / `Path`
the merged env uses, then build `runtimeEnv`. No new helpers, no
adapter-utils changes.
## Verification
Manual repro before the fix:
1. Create a pi_local agent wired to a paperclip skill (e.g.
paperclip-control).
2. Wake the agent on an in_review issue with an AGENTS.md that starts
with `paperclip-get-issue "$PAPERCLIP_TASK_ID"`.
3. Session file: `{ "role": "toolResult", "isError": true, "content": [{
"text": "/bin/bash: paperclip-get-issue: command not found\n\nCommand
exited with code 127" }] }`.
After the fix: same wake; `paperclip-get-issue` resolves and returns the
issue JSON; agent proceeds.
Local commands:
```
pnpm --filter @paperclipai/adapter-pi-local typecheck # clean
pnpm --filter @paperclipai/adapter-pi-local build # clean
pnpm --filter @paperclipai/server exec vitest run \
src/__tests__/pi-local-execute.test.ts \
src/__tests__/pi-local-adapter-environment.test.ts \
src/__tests__/pi-local-skill-sync.test.ts
# 5/5 passing
```
No new tests: the existing `pi-local-skill-sync.test.ts` covers skill
symlink injection (upstream of the PATH step), and
`pi-local-execute.test.ts` covers the spawn path; this change only
augments env on the same spawn path.
## Risks
Low. Pure PATH augmentation on the child env. Edge cases:
- Zero skills installed → no PATH change (guarded by
`skillBinDirs.length > 0`).
- Duplicate bin dirs already on PATH → deduped; no pollution on re-runs.
- Windows `Path` casing → falls back correctly when merged env uses
`Path` instead of `PATH`.
- Skill dir without `bin/` subdir → joined path simply won't resolve;
harmless.
No behavioral change for pi_local agents that don't use skill-provided
commands.
## Model Used
- Claude, `claude-opus-4-7` (1M context), extended thinking enabled,
tool use enabled. Walked pi-local/cursor-local/claude-local and
adapter-utils to isolate the gap, wrote the inlined fix, and ran
typecheck/build/test locally.
## Checklist
- [x] Thinking path from project context to this change
- [x] Model used specified
- [x] Checked ROADMAP.md — no overlap
- [x] Tests run locally, passing
- [x] Tests added — new case in
`server/src/__tests__/pi-local-execute.test.ts`; verified it fails when
the fix is reverted
- [ ] UI screenshots — N/A (backend adapter change)
- [x] Docs updated — N/A (internal adapter, no user-facing docs)
- [x] Risks documented
- [x] Will address reviewer comments before merge
## Thinking Path
> - Paperclip is the control plane for autonomous AI companies.
> - The public README is the first place many operators and contributors
learn what the product already includes.
> - The existing README explained the product promise but did not give a
compact, concrete tour of the major systems behind it.
> - This made Paperclip easier to underestimate as a wrapper around
agents instead of a full control plane with identity, work, execution,
governance, budgets, plugins, and portability.
> - This pull request adds an under-the-hood README section that names
those systems and shows how adapters connect into the server.
> - Greptile caught consistency gaps between the diagram and prose, so
the final version aligns the system labels and adapter examples across
both surfaces.
> - The benefit is a clearer first-read model of Paperclip's
architecture and shipped capabilities without changing runtime behavior.
## What Changed
- Added a `What's Under the Hood` section to `README.md`.
- Added an ASCII architecture diagram for the Paperclip server and
external agent adapters.
- Added a systems table covering identity, org charts, tasks, heartbeat
execution, workspaces, governance, budgets, routines, plugins,
secrets/storage, activity/events, and company portability.
- Addressed Greptile feedback by aligning diagram labels with table rows
and grouping adapter examples consistently.
## Verification
- `git diff --check public-gh/master...HEAD`
- Attempted `pnpm exec prettier --check README.md`, but this checkout
does not expose a `prettier` binary through `pnpm exec`.
- Greptile review rerun passed after addressing its two comments; review
threads are resolved.
- Remote PR checks passed on the latest head: `policy`, `verify`, `e2e`,
`security/snyk (cryppadotta)`, and `Greptile Review`.
- Not run locally: Vitest/build suites, because this is a README-only
documentation change and the PR's remote `verify` job ran typecheck,
tests, build, and release canary dry run.
## Risks
- Low runtime risk: documentation-only change.
- The main risk is wording drift if the README overstates or
underspecifies evolving product capabilities; the section was aligned
against the current product/spec docs and roadmap.

## Thinking Path
> - Paperclip orchestrates AI agents for zero-human companies
> - The external adapter plugin system (#2218) lets adapters ship as npm
modules loaded via `server/src/adapters/plugin-loader.ts`; since #4296
merged, each `ServerAdapterModule` can declare `sessionManagement`
(`supportsSessionResume`, `nativeContextManagement`,
`defaultSessionCompaction`) and have it preserved through the init-time
load via the new `resolveExternalAdapterRegistration` helper
> - #4296 fixed the init-time IIFE path at
`server/src/adapters/registry.ts:363-369` but noted that the hot-install
path at `server/src/routes/adapters.ts:174
registerWithSessionManagement` still unconditionally overwrites
module-provided `sessionManagement` during `POST /api/adapters/install`
> - Practical impact today: an external adapter installed via the API
needs a Paperclip restart before its declared `sessionManagement` takes
effect — the IIFE runs on next boot and preserves it, but until then the
hot-install overwrite wins
> - This PR closes that parity gap: `registerWithSessionManagement`
delegates to the same `resolveExternalAdapterRegistration` helper
introduced by #4296, unifying both load paths behind one resolver
> - The benefit is consistent behaviour between cold-start and
hot-install: no "install then restart" ritual; declared
`sessionManagement` on an external module is honoured the moment `POST
/api/adapters/install` returns 201
## What Changed
- `server/src/routes/adapters.ts`: `registerWithSessionManagement`
delegates to the exported `resolveExternalAdapterRegistration` helper
(added in #4296). Honours module-provided `sessionManagement` first,
falls back to host registry lookup, defaults `undefined`. Updated the
section comment to document the parity-with-IIFE intent.
- `server/src/routes/adapters.ts`: dropped the now-unused
`getAdapterSessionManagement` import.
- `server/src/adapters/registry.ts`: updated the JSDoc on
`resolveExternalAdapterRegistration` — previously said "Exported for
unit tests; runtime callers use the IIFE below", now says the helper is
used by both the init-time IIFE and the hot-install path in
`routes/adapters.ts`. Addresses Greptile C1.
- `server/src/__tests__/adapter-routes.test.ts`: new integration test —
installs a mocked external adapter module carrying a non-trivial
`sessionManagement` declaration and asserts
`findServerAdapter(type).sessionManagement` preserves it after `POST
/api/adapters/install` returns 201.
- `server/src/__tests__/adapter-routes.test.ts`: added
`findServerAdapter` to the shared test-scope variable set so the new
test can inspect post-install registry state.
## Verification
Targeted test runs from a clean tree on
`fix/external-session-management-hot-install` (rebased onto current
`upstream/master` now that #4296 has merged):
- `pnpm test server/src/__tests__/adapter-routes.test.ts` — 6 passed
(new test + 5 pre-existing)
- `pnpm test server/src/__tests__/adapter-registry.test.ts` — 15 passed
(ensures the IIFE path from #4296 continues to behave correctly)
- `pnpm -w run test` full workspace suite — 1923 passed / 1 skipped
(unrelated skip)
End-to-end smoke on file:
[`@superbiche/cline-paperclip-adapter@0.1.1`](https://www.npmjs.com/package/@superbiche/cline-paperclip-adapter)
and
[`@superbiche/qwen-paperclip-adapter@0.1.1`](https://www.npmjs.com/package/@superbiche/qwen-paperclip-adapter),
both public on npm, both declare `sessionManagement`. With this PR in
place, the "restart after install" step disappears — the declared
compaction policy is active immediately after the install response.
## Risks
- Low risk. The change replaces an inline mutation with a call to a
helper that already has dedicated unit coverage (#4296 added three tests
for `resolveExternalAdapterRegistration` covering module-provided,
registry-fallback, and undefined paths). Behaviour is a strict superset
of the prior path — externals that did not declare `sessionManagement`
continue to get the hardcoded-registry lookup; externals that did
declare it now have those values preserved instead of overwritten.
- No migration impact. The stored plugin records
(`~/.paperclip/adapter-plugins.json`) are unchanged. Existing
hot-installed adapters behave correctly before and after.
- No behavioural change for builtin adapters; they hit
`registerServerAdapter` directly and never flow through
`registerWithSessionManagement`.
## Model Used
- Provider and model: Claude (Anthropic) via Claude Code

- Reasoning mode: standard (no extended thinking on this PR)
- Tool use: yes — file edits, subprocess invocations for
builds/tests/git via the Claude Code harness

## Thinking Path
> - Paperclip orchestrates AI agents for zero-human companies
> - Adapters are how paperclip hands work off to specific agent
runtimes; since #2218, external adapter packages can ship as npm modules
loaded via `server/src/adapters/plugin-loader.ts`
> - Each `ServerAdapterModule` can declare `sessionManagement`
(`supportsSessionResume`, `nativeContextManagement`,
`defaultSessionCompaction`) — but the init-time load at
`registry.ts:363-369` hard-overwrote it with a hardcoded-registry lookup
that has no entries for external types, so modules could not actually
set these fields
> - The hot-install path at `routes/adapters.ts:179` →
`registerServerAdapter` preserves module-provided `sessionManagement`,
so externals worked after `POST /api/adapters/install` — *until the next
server restart*, when the init-time IIFE wiped it back to `undefined`
> - #2218 explicitly deferred this: *"Adapter execution model, heartbeat
protocol, and session management are untouched."* This PR is the natural
follow-up for session management on the plugin-loader path
> - This PR aligns init-time registration with the hot-install path:
honor module-provided `sessionManagement` first, fall back to the
hardcoded registry when absent (so externals overriding a built-in type
still inherit its policy). Extracted as a testable helper with three
unit tests
> - The benefit is external adapters can declare session-resume
capabilities consistently across cold-start and hot-install, without
requiring upstream additions to the hardcoded registry for each new
plugin
## What Changed
- `server/src/adapters/registry.ts`: extracted the merge logic into a
new exported helper `resolveExternalAdapterRegistration()` — honors
module-provided `sessionManagement` first, falls back to
`getAdapterSessionManagement(type)`, else `undefined`. The init-time
IIFE calls the helper instead of inlining an overwrite.
- `server/src/adapters/registry.ts`: updated the section comment (lines
331–340) to reflect the new semantics and cross-reference the
hot-install path's behavior.
- `server/src/__tests__/adapter-registry.test.ts`: new
`describe("resolveExternalAdapterRegistration")` block with three tests
— module-provided value preserved, registry fallback when module omits,
`undefined` when neither provides.
## Verification
Targeted test run from a clean tree on
`fix/external-session-management`:
```
cd server && pnpm exec vitest run src/__tests__/adapter-registry.test.ts
# 1 test file, 15 tests passed, 0 failed (12 pre-existing + 3 new)
```
Full server suite via the independent review pass noted under Model
Used: **1,156 tests passed, 0 failed**.
Typecheck note: `pnpm --filter @paperclipai/server exec tsc --noEmit`
surfaces two errors in `src/services/plugin-host-services.ts:1510`
(`createInteraction` + implicit-any). Verified by `git stash` + re-run
on clean `upstream/master` — they reproduce without this PR's changes.
Pre-existing, out of scope.
## Risks
- **Low behavioral risk.** Strictly additive: externals that do NOT
provide `sessionManagement` continue to receive exactly the same value
as before (registry lookup → `undefined` for pure externals, or the
builtin's entry for externals overriding a built-in type). Only a new
capability is unlocked; no existing behavior changes for existing
adapters.
- **No breaking change.** `ServerAdapterModule.sessionManagement` was
already optional at the type level. Externals that never set it see no
difference on either path.
- **Consistency verified.** Init-time IIFE now matches the post-`POST
/api/adapters/install` behavior — a server restart no longer regresses
the field.
## Note
This is part of a broader effort to close the parity gap between
external and built-in adapters. Once externals reach 1:1 capability
coverage with internals, new-adapter contributions can increasingly be
steered toward the external-plugin path instead of the core product — a
trajectory CONTRIBUTING.md already encourages ("*If the idea fits as an
extension, prefer building it with the plugin system*").
## Model Used
- **Provider**: Anthropic
- **Model**: Claude Opus 4.7
- **Exact model ID**: `claude-opus-4-7` (1M-context variant:
`claude-opus-4-7[1m]`)
- **Context window**: 1,000,000 tokens
- **Harness**: Claude Code (Anthropic's official CLI), orchestrated by
@superbiche as human-in-the-loop. Full file-editing, shell, and `gh`
tool use, plus parallel research subagents for fact-finding against
paperclip internals (plugin-loader contract, sessionCodec reachability,
UI parser surface, Cline CLI JSON schema).
- **Independent local review**: Gemini 3.1 Pro (Google) performed a
separate verification pass on the committed branch — confirmed the
approach & necessity, ran the full workspace build, and executed the
complete server test suite (1,156 tests, all passing). Not used for
authoring; second-opinion pass only.
- **Authoring split**: @superbiche identified the gap (while mapping the
external-adapter surface for a downstream adapter build) and shaped the
plan — categorising the surface into `works / acceptable /
needs-upstream` buckets, directing the surgical-diff approach on a fresh
branch from `upstream/master`, and calling the framing ("alignment bug
between init-time IIFE and hot-install path" rather than "missing
capability"). Opus 4.7 executed the fact-finding, the diff, the tests,
and drafted this PR body — all under direct review.
