Features - claude-code: augments the official Anthropic Feature when present (install: auto/native/none), ships claude-host (resume one session by UUID via HOST_SESSION), owns CLAUDE_CONFIG_DIR in a named volume with a post-create hook. Fixes a set -u trap bug in the native installer. - git (new): worktree-aware wrapper that scopes GIT_DIR/GIT_WORK_TREE to the checkout (nested worktrees, temp folders, init/clone), post-create safe.directory and core.hooksPath, GIT_CONFIG_GLOBAL in a volume. - gh (new): verified release install when absent, GH_CONFIG_DIR volume, git credential helper from gh. - az (new): augments the official azure-cli Feature, AZURE_CONFIG_DIR volume, bicep from PATH. - common (new): dcf-persist, the shared helper behind every hook; vendored into the Features that use it, checked identical by lint. - coder-cli, argocd: own their login state the same way. - devcontainer-cli: --docker-path only for subcommands that take it. Host side (bootstrap) - devcontainer.yml: the Task 3.45 include env: bug fixed, so .env values reach the tasks (no dc:* passthrough needed; dc is an include alias); new pwsh, claude and homes tasks; in-container runs branch in the template because per-command if: is ignored. - devcontainer:homes (pwsh + bash twins) creates host folders for repos that bind-mount a Feature's state target to the host disk. - env_mnt removed everywhere: the checkout is the only thing on disk. Docs: README "How the pieces fit" (the paradigm), CONTRIBUTING conventions for augmentations, state ownership, vendored helpers and Taskfile pitfalls. CI matrices and the global scenario cover the new Features.

The claude-code augment_official scenario matched "node" in the path of the official Feature's claude, which the node Feature puts under /usr/local/share/nvm/ current/bin; match nvm or node and require it is not our native binary. Both passed in the wslc harness only because no hook ran there first.

The checkout's git dir (outside OneDrive) is bind-mounted the way the consumer repos do it, with the git Feature's wrapper scoping GIT_DIR. - Host paths in every example use ${localEnv:USERPROFILE} only: on this Windows host both USERPROFILE and HOME are set, so concatenating the two doubled the path and failed the first start. - gh-setup makes the global git config folder usable itself (dcf-persist) instead of relying on the git hook having run first; installsAfter may only name published Features (documented in CONTRIBUTING). - post-create.sh reports what the Features set up instead of redoing it.

Job state lives in the Feature's volume; every path and model is a DEVHOST_* / _MODEL setting; no person is named, the person is "the Operator". Verified on Debian with a stub claude, and by 35 stdlib unit tests that now run in `task lint` and CI. This repository adopts it: devhost in its own devcontainer, the scaffold run inside it, CLAUDE.md written for the collection, the pre-commit guard, and a seeded TODO.md with what is next (merge or split PR #10, release, first sign-in and first back runs, consumers' adoption).

The model edits `$DEVHOST_BACKLOG` itself with `Read` and `Edit` on that one file (`Bash` off): adds items (`- [ ] **TD-nn Title** (owner). ... Added YYYY-MM-DD.`) under Now/Next, decisions under `## Decisions for the Operator`, ticks finished items. The backlog guard (`guards.py backlog`) undoes a run that deleted, reworded or reordered a line; then the name guard runs on the file. +- **librarian** (`LIBRARIAN_MODEL`, sonnet): on `Stop` and `SubagentStop`, after 8000 new characters and ten minutes between runs (a stake wakes it). Edits `$DEVHOST_LEXICON` and `$DEVHOST_ADR_DIR/**` with `Read`, `Glob`, `Grep`, `Edit` (`Bash` off): new terms in the lexicon's style, new ADRs from the folder's `0000-template.md`, an index row in its `README.md`, a `superseded by` status on a replaced ADR. The docs guard (`guards.py docs`) restores the snapshot when an existing lexicon line or ADR changed beyond its Status row; the name guard runs on the lexicon and every new ADR. +- **tester** (`TESTER_MODEL`, none: cost 0 on its metrics line): on every `Stop`. Hashes the code under `TESTER_PATHS` (HEAD, the diff and untracked files; names, sizes and times outside git) and, when it changed since its last run, runs `TESTER_CMD` (`task test` when the root Taskfile has a `test` task; nothing otherwise, logged once) with `DEVHOST_JOB_CHILD=1` under `TESTER_TIMEOUT`. Speaks only when the suite is red (`tests red (...): N failed, first: ...`) or green again after red; a timed-out run keeps no hash and tries again after the next turn. + +All four: one `claude -p --model <model> --settings '{"disableAllHooks": true}' --no-session-persistence --output-format json` run under a 540 s timeout (none for the tester), the stretch condensed by `devhost-condense` (the engineer's words, the inter's visible replies, which tools ran with their paths or commands, cons' hand-backs; never thinking or tool output; the latest 40 000 characters), the offset advanced only when the run ended `changed` or `nothing`, one metrics line per run in `runs.jsonl` (time, job, mode, agent type, session, engineer, model, stretch size, stakes, status, guard undos, duration, cost, tokens). Sub-agents of the kinds in `DEVHOST_JOB_SKIP_AGENTS` (read-only lookups) are not jobs. + +## State + +`DEVHOST_STATE` (`/var/lib/devcontainer-features/devhost`, the named volume `devhost-state-${devcontainerId}`) holds `<job>/offsets/<session id>` (how far each back has read each transcript), `<job>/lock`, `<job>/job.log`, `<job>/pending-<session id>` and `since-<session id>` (the scribe), `tester/code_hash` and `last_result`, and `runs.jsonl`. Nothing of it belongs in the checkout, so a synced checkout never carries it and the ledger diff is only the entries. The post-create hook (`devhost-setup`, also `task devhost:setup`) creates the directory and hands it to the remote user through `dcf-persist`, and reports what backs it; for the host disk, bind-mount a host folder on the same target as the other Features of this collection do. `task devhost:log` tails every `job.log`; `task devhost:jobs:state` lists sessions read, pending items, held locks and the tester's last verdict. + +## Settings + +Every script reads the same variables; a repository overrides them in `containerEnv` (or `.devcontainer/.env`), none needs a rebuild.

The original's ledger lists the mistakes already fixed and kept fixed here: stakes mid-paragraph are missed, so a stake stands on its own line; a reply is written once per content block and the first record can carry a partial count, so the cost script keeps the fullest record; the guards undo a run that rewords or reorders rather than trust the brief; a test fixture under a container-wide `GIT_DIR` committed onto the real branch, hence the git wrapper and `DEVHOST_JOB_CHILD` on the suite; the librarian woken at the scribe's rate had nothing to do a third of the time, hence its own thresholds; the state out of the checkout, so nothing is synced or committed by mistake.
