## Model Tiering
|
||||
|
||||
Model choice is a standard, not a preference. Delegating a mechanical grep to a
|
||||
frontier reasoning model wastes budget; sending a security review to a cheap tier
|
||||
produces a review that passes and proves nothing. Both are defects.
|
||||
|
||||
Tiers are named by **capability class**, so the standard survives a model
|
||||
generation. An operator binds each class to a concrete model id.
|
||||
|
||||
| Class | Use for |
|
||||
| ------------- | ----------------------------------------------------------------------------------------- |
|
||||
| `search` | grep/glob, file location, status and health checks, one-line mechanical edits |
|
||||
| `build` | feature implementation, test writing, bugfixes, routine refactors |
|
||||
| `judge` | code review, planning, API/compat-sensitive changes |
|
||||
| `adversarial` | security review, ambiguous architecture, anything where a wrong "looks fine" is expensive |
|
||||
|
||||
Rules:
|
||||
|
||||
1. **Start at the cheapest class that can do the task; escalate on evidence, not
|
||||
on nerves.** Omitting a tier is not neutral — it inherits the caller's model,
|
||||
which is usually the most expensive one.
|
||||
2. **Compat-sensitive work escalates one class.** A change that must interoperate
|
||||
with an existing contract is judged, not just built.
|
||||
3. **A tier assignment is benchmarked, not asserted.** Move a task class to a
|
||||
cheaper tier only against a blind A/B on real work from this codebase, ranked
|
||||
by someone other than the author. "It seemed fine" is not evidence.
|
||||
4. **Reviewer independence beats reviewer size.** An `adversarial` verdict from
|
||||
the model that wrote the code is not a second opinion (see Constitution gate 16).
|
||||
|
||||
### Where the binding lives
|
||||
|
||||
The class→model map is operator configuration, never framework source: model
|
||||
availability, cost, and quotas differ per operator and per host.
|
||||
|
||||
Resolution order, first hit wins:
|
||||
|
||||
1. the config service (DB-backed, surfaced and editable in the Mosaic webUI)
|
||||
2. a local operator file (`STANDARDS.local.md`, or `policy/` where the runtime
|
||||
injects it)
|
||||
3. the framework default — the class names above, with no binding
|
||||
|
||||
Only layer 1 is auditable across a fleet, so it is the target end state; layers 2
|
||||
and 3 exist so a host with no config service still runs. A local override that
|
||||
silently disagrees with the config service is drift — the same failure class the
|
||||
tool-index gate exists to catch, and it belongs in `mosaic doctor`.
|
||||
|

**Workspace placement is derived, not chosen.** `mosaic-worktree.sh new <branch>` takes a branch
|
||||
name and nothing else. Every path comes out of `git worktree list --porcelain` — main worktree,
|
||||
repo name, parent dir, then `<parent>/<repo>-worktrees/<branch-slug>`. There is no placement flag
|
||||
because a decision an agent has to make is a decision that drifts: the rule "big work goes on a work
|
||||
filesystem" already existed in prose and 255 GB accumulated in `$HOME` across 842 directories
|
||||
anyway, under five simultaneous conventions on a single host.
|
||||
|
||||
```bash
|
||||
~/.config/mosaic/tools/git/mosaic-worktree.sh new <branch> [--from <base>]
|
||||
~/.config/mosaic/tools/git/mosaic-worktree.sh path <branch> # derived path, no side effect
|
||||
~/.config/mosaic/tools/git/mosaic-worktree.sh list # this repo's worktrees + state
|
||||
~/.config/mosaic/tools/git/mosaic-worktree.sh rm <branch> # removal is part of the task

||||
|
||||
Worktrees rather than clones, because `git worktree list` makes every checkout enumerable — a bare
|
||||
clone dropped somewhere on disk can never be safely reclaimed, so it is never reclaimed. `rm` and
|
||||
`gc` decide by **evidence, never by size or age**: a worktree is reclaimable only when
|
||||
`git status --porcelain` is empty _and_ `git rev-list --count HEAD --not --remotes` is 0. Anything
|
||||
else is preserved and reported. `--force` exists and is yours to type deliberately.

`wrapper-guard.sh` is registered as a Claude Code `PreToolUse` hook on `Bash` (see
|
||||
`runtime/claude/settings.json`). It blocks exactly three things and lets everything else through:
|
||||
a `git clone`/`git worktree add` targeting `$HOME`; a raw provider-API **write** to an endpoint that
|
||||
already has a wrapper above (reads are untouched — they are how you gather evidence); and the
|
||||
literal `"event": "APPROVE"`. For a genuine gap no wrapper can express, prefix
|
||||
`MOSAIC_WRAPPER_OVERRIDE=1`. Reaching for the override twice for the same call means the wrapper has
|
||||
a missing flag — extend the wrapper.
|
||||
|
||||
```bash
|

~/.config/mosaic/tools/git/issue-create.sh --help

# CI queue guard (required before push/merge; defaults to the checked-out branch)

||||
~/.config/mosaic/tools/git/ci-queue-wait.sh --purpose push|merge
|
||||
```
|
||||
|
||||
**Review dialect — the reason `pr-review.sh` is not optional.** Gitea's approve event is
|
||||
`APPROVED`; GitHub's is `APPROVE`. Send GitHub's spelling to a Gitea host and it answers **HTTP
|
||||
200**, files the review as PENDING, and then rejects the submit with `422 review stay pending` — the
|
||||
verdict looks placed and is not. (`REQUEST_CHANGES` is spelled identically on both, so only the
|
||||
approve path carries the trap.) `pr-review.sh` sends the correct token for the detected provider.
|
||||
Whatever you use, re-read `GET /pulls/{n}/reviews` and assert the state before reporting a verdict
|
||||
placed.
|
||||
|
||||
The guard exits nonzero for any provider-asserted non-green, missing, or malformed CI state. If credentials or the provider are unavailable, it emits `CANNOT_ASSERT` and writes a JSONL audit record. Push degrades to exit 0 so recovery work is not bricked; merge holds with retryable exit 75 until the provider recovers, then self-clears without manual reset. Neither outcome is evidence that CI was clear. `pr-merge.sh` automatically inspects the exact PR head repository and full commit SHA rather than its `main` base; this also handles fork PRs without branch-name ambiguity. Pass `--expect-head <approved-full-sha>` to bind a commit-specific review or merge-gate verdict; Gitea uses atomic `head_commit_id` and GitHub uses `--match-head-commit`.

# left the class, and the third is worth spelling out because it is the subtlest

# and it was mine: replacing quote characters with whitespace is token
|

# SEPARATION, not quote removal. A shell removes a quote WITHOUT splitting the
|

# word around it, so `cu"rl"` is one word naming curl, while whitespace made it
|
||||
# two words naming neither. `"/usr/bin/curl"` blocked under that version only
|
||||
# because the whitespace happened to land after a slash — a passing case that
|
||||
# established nothing.
|
||||
#
|
||||
# So the characters are DELETED rather than replaced, which is what quote removal
|
||||
# is, and backslashes go with them because escaping is ordinary word formation

# too. Deletion also handles substitution: `$(which curl)` becomes `which curl`,

# where the name is a word on its own.

The guard's job here is to answer one question — does this check out under

\$HOME — and it cannot answer it without a usable \$HOME. An unanswerable
|

question is not a cleared one, so this refuses rather than guesses. (\$HOME
|

empty, unset, and "/" are all treated the same way: none of them is a home
|
||||
directory, and "/" would match every path there is.)
|
||||
|
||||
Set HOME to the account's home directory and re-run, or use the helper, which
|
||||
derives the path and never consults \$HOME at all:
|
||||
|
||||
$W/mosaic-worktree.sh new <branch>
|

EOF

exit 2

|

cat <<EOF
|

BLOCKED: this checks a repository out under \$HOME.
|
||||
|
||||
\$HOME holds configuration, credentials, state and caches. It does not hold
|
||||
checkouts, worktrees, scratch files, or build output. One fleet host's /home hit
|
||||
100% (394 G) with 255 GB of agent workspaces accumulated exactly this way.
|
||||
|
||||
Use the helper, which derives the path so you do not have to choose one:
|
||||
|
||||
~/.config/mosaic/tools/git/mosaic-worktree.sh new <branch> # /src/<repo>-worktrees/<slug>
|
||||
~/.config/mosaic/tools/git/mosaic-worktree.sh path <branch> # show where it would go
|
||||
~/.config/mosaic/tools/git/mosaic-worktree.sh rm <branch> # removal is part of the task
|
||||
|
||||
Worktrees, not clones: they share the object store, and \`git worktree list\`
|
||||
makes every one of them enumerable — which is the only reason cleanup can
|
||||
ever be safe.

# ---- 2/3. provider API writes ---------------------------------------------
|
||||
# A raw provider write this guard cares about is two things: a WRITE, and a URL
|
||||
# naming an endpoint a Mosaic wrapper already owns. Reads are untouched — they
|
||||
# are how you gather evidence — and the many endpoints with no wrapper flow
|
||||
# through.
|
||||
#
|
||||
# It deliberately does NOT ask which program makes the call, or whether that
|
||||
# program sits at shell command position. It used to, and that is the whole
|
||||
# history of this file. Answering "is this code or is this data" from the text
|
||||
# of a shell command required a skeleton with quoted spans and heredoc bodies
|
||||
# removed, an invoker list for the forms where a shell executes quoted text, a
|
||||
# prefix list for `env`/`sudo`/`timeout`, option-value skipping, and
|
||||
# backslash-newline joining. Five rounds of adversarial review put nineteen
|
||||
# writes straight through it, and every one had the same shape: the client was
|
||||
# ABSENT from the skeleton, so the guard allowed. Variables, line continuations,
|
||||
# command prefixes, option values, pipes into a shell, and finally command
|
||||
# substitution inside the very quotes the skeleton was discarding:
|
||||
# echo "$(curl -d@b .../issues/1/comments)"
|
||||
# msg="$(curl -d@b .../issues/1/comments)"
|
||||
# Classifying code against data in shell text with sed and awk is not a hard
|
||||
# problem, it is the wrong problem. It was not even portable: under CI's busybox
|
||||
# awk the quote-stripping silently failed, the skeleton kept every quoted span,
|
||||
# and the guard started refusing ordinary prose instead — which is the other way
|
||||
# a control like this dies.
|
||||
#
|
||||
# So the client detection is gone, and with it that entire failure class: what
|
||||
# is left cannot fail open by hiding the caller, because it never looks for one.
|
||||
# It looks for the payload. Something that names a wrapped endpoint and carries
|
||||
# a body is refused however it is spelled — curl, wget, `python -c`, or a form
|
||||
# nobody has thought of yet.
|
||||
#
|
||||
# The cost is real and belongs in the open, because over-blocking is how a hook
|
||||
# gets switched off: QUOTING one of these calls on a Bash command line now
|
||||
# blocks too. `grep -R "curl -d .../issues" docs/` is refused, and so is echoing
|
||||
# an example into a file. There is no textual way to tell a quoted example from
|
||||
# a quoted command — that is exactly the finding above — so the rule is the one
|
||||
# an agent can hold in mind without a parser:
|
||||
#
|
||||
# do not put a raw write to a wrapped forge endpoint on a Bash command line,
|
||||
# not even inside quotes.
|
||||
#
|
||||
# Write the example with a file-writing tool, or leave the body flag out of it.
|
||||
# That is a deliberate narrowing of scope, not an oversight. This hook stops
|
||||
# mistakes; it is not a sandbox, and pretending otherwise is how you get a
|
||||
# control nobody can trust the boundaries of.
|
||||
#
|
||||
# Scoped to commands that are provider-API-shaped, so nothing else is even
|
||||
# considered. The first version of this scope gate asked only for `https?://`,
|
||||
# and review found the absence shape had simply moved to the new boundary:
|
||||
# gh api -X POST repos/a/b/pulls/1/reviews -f event=APPROVE
|
||||
# tea api -X POST repos/a/b/issues/1/comments -f body=x
|
||||
# curl -X POST -d x git.example.invalid/api/v1/repos/a/b/issues
|
||||
# all carry a real write to a wrapped endpoint and none carries a scheme, so the
|
||||
# guard never asked the write question at all. Gate 7 covers raw provider CLIs,
|
||||
# so these are in scope and the gate now names the shapes they come in.
|
||||
#
|
||||
# Then review found the same absence at the same boundary a second time, in the
|
||||
# one provider whose paths carry no version marker at all:
|
||||
# curl -X POST -d x api.github.com/repos/a/b/issues
|
||||
# GitHub's API is `api.github.com/repos/...`; Gitea's is `/api/v1/repos/...`.
|
||||
# Asking for `/api/v[0-9]` therefore admitted the schemeless Gitea write and
|
||||
# excluded the schemeless GitHub one — a gate calibrated to one dialect's
|
||||
# spelling rather than to what identifies a provider API. So the gate names both
|
||||
# markers: a version segment, and the `/repos/` path that every forge API uses
|
||||
# to address a repository.
|
||||
#
|
||||
# Adding alternatives to a scope gate can only make it stricter — it cannot
|
||||
# create a new allow — which is why this is a list of triggers rather than a
|
||||
# model of any one caller. Downstream, a block still requires a body flag AND
|
||||
# either a mapped endpoint or an unreadable one, so widening the gate widens
|
||||
# what is CONSIDERED, not what is refused.
|
||||
#
|
||||
# Residual, stated rather than implied: a caller who splits `/repos/` itself in
|
||||
# a schemeless GitHub URL (`h=api.github.com/rep; q=os/a/b/issues`) leaves no
|
||||
# literal marker anywhere and is out of scope. That is the same boundary as
|
||||
# splitting the hostname — no longer a mistake anyone makes by accident.
|
||||
#
|
||||
# Boundary, deliberate and worth stating: this covers the `api` subcommand,
|
||||
# which is a raw API call wearing a CLI. Provider PORCELAIN (`tea pulls create`,
|
||||
# `gh pr merge`) is NOT covered — catching that means modelling every CLI's verb
|
||||
# grammar, which is the parser mistake again in a new costume. Porcelain is a
|
||||
# gate-7 gap for prose and review to hold, not this hook.
|
||||
# ---- curl whose request lives in a file ------------------------------------
|
||||
# curl takes its options from a file with -K/--config, and that file may carry
|
||||
# the method, the body, the headers AND THE URL. That last one is why this test
|
||||
# cannot live inside the API-shape gate below, which is where it was first put:
|
||||
#
|
||||
# curl --config /tmp/provider-write.cfg
|
||||
#
|
||||
# has no URL, no /repos/, no `gh api` — nothing API-shaped in the text at all —
|
||||
# so it never entered the branch that was supposed to refuse it, and the guard
|
||||
# reported clean on the exact capability the check exists to deny. The check was
|
||||
# guarded by a condition the thing it guards against defeats. It is now asked of
|
||||
# any curl, because "is this a provider call" is not answerable about a command
|
||||
# whose URL is in a file, and a question that cannot be asked is not a question
|
||||
# that came back clean.
|
||||
#
|
||||
# The spelling is deliberately loose. curl accepts the value attached to the
|
||||
# short flag (`-K/tmp/req`, verified) and inside a bundle (`-sK /tmp/req`), and a
|
||||
# guard that recognizes only the space- and equals-separated forms is defeated by
|
||||
# deleting one character. Scoped to curl so that `eslint --config .eslintrc.json`
|
||||
# and every other tool with a --config flag are untouched.
|
||||
#
|
||||
# curl is recognized as a NAME, through $CMD_NAMES and $NAME_PREFIX — see the
|
||||
# comment on those at the top of the file for why matching the bare word, and
|
||||
# then matching the unquoted basename, were both the same mistake at different
|
||||
# depths. A wrapper script that execs curl on the operator's behalf is still
|
||||
# invisible here, because neither the name nor the request appears in the
|
||||
# command text at all. That is a limit of inspecting a command string rather
|
||||
# than a defect this pattern can close, and it is stated rather than left for
|
||||
# the next reader to find.
|
||||
# The FLAG is read from $CMD_NAMES too. It is the same recognition problem as
|
||||
# the name — `--con"fig"` is one word spelling --config — and no review has
|
||||
# raised it yet only because the name was the easier half to reach. Reading both

# check-tools-index.sh — assert every shipped tool is discoverable from the

|

#
|
||||
# WHY THIS GATE EXISTS
|
||||
# --------------------
|
||||
# The framework ships 26 git wrappers. Before this gate, 20 of them were named
|
||||
# in neither `defaults/TOOLS.md` nor `guides/TOOLS-REFERENCE.md`. One of the
|
||||
# undocumented ones was `pr-review.sh` — the wrapper that carries the
|
||||
# APPROVED/APPROVE provider-dialect split.
|
||||
#
|
||||
# The observable consequence, on a live fleet host: an agent needing to place a
|
||||
# review verdict reached for raw `curl`, sent GitHub's `APPROVE` to a Gitea
|
||||
# host, and got HTTP 200 with the review silently filed PENDING — three times,
|
||||
# because nothing about the failure pointed at the wrapper that already handled
|
||||
# it correctly. The agent was not ignoring Constitution gate 7. It was obeying
|
||||
# an index that said the tool did not exist.
|
||||
#
|
||||
# That is not a discipline problem and no amount of prose fixes it. A wrapper
|
||||
# that is not in the resident index is, from inside a session, indistinguishable
|
||||
# from a wrapper that was never written. So the invariant is mechanical:
|
||||
#
|
||||
# shipping a tool and documenting it are the same commit, or CI fails.
|
||||
#
|
||||
# WHAT IT CHECKS
|
||||
# --------------
|
||||
# forward every non-excluded tool in an ENFORCED suite is named in at least
|
||||
# one index document (missing tool -> undiscoverable -> FAIL)
|
||||
# reverse every `<name>.sh` an index document attributes to an enforced
|
||||
# suite exists on disk (stale reference -> agent runs a ghost -> FAIL)
|
||||
#
|
||||
# Suites outside the enforced set are reported with a coverage percentage but do
|
||||
# not fail the build, so the ratchet can be tightened one suite per PR instead of
|
||||
# landing as one unreviewable sweep. `--strict` fails on those too.
|
||||
#
|
||||
# WHY THE ENFORCED LIST LIVES HERE AND NOT IN A MARKER INSIDE THE DOC
|
||||
# -------------------------------------------------------------------
|
||||
# `TOOLS.md` is operator-owned (see framework-manifest.txt). A marker inside it
|
||||
# would let an operator silence this gate by editing their own copy — the gate
|
||||
# would then be strongest exactly where it is least needed and absent where it
|
||||
# is needed most. The list is framework-owned and changes only through a
|
||||
# reviewed PR.
|
||||
#
|
||||
# Usage:
|
||||
# check-tools-index.sh [--tools-dir DIR] [--doc FILE]... [--strict] [--self-test]
|
||||
#
|
||||
# Exit: 0 = every enforced suite fully discoverable · 1 = drift · 2 = bad usage

|
||||
set -euo pipefail
|
||||
|

# Suites whose coverage is a HARD requirement. Add a suite here only together
|
||||
# with the doc changes that make it pass.
|

#
|
||||
