Review cleanups for the tools/reasoning-effort model test change:
- Extract a shared parse_query_enum helper in the models handler in
place of two copy-pasted parse-or-400 match blocks.
- Collapse the duplicated basic-probe pipeline in fabro-llm behind a
single basic_probe core; name the shared EXPANDED_MAX_TOKENS budget.
- Pass &ModelTestArgs to test_models_via_server instead of threading
five of its fields positionally.
- Dedupe the two forwarding CLI integration tests behind a helper.
- Derive clap::ValueEnum for ReasoningEffort behind a feature-gated
clap dep (same pattern as MergeStrategy in fabro-types) so --help,
cli.mdx, and error output list effort values from the enum instead
of a hand-written list that drifts.

- Use the shared node_with_attrs test helper
- Drop an executor test that duplicated existing retry-target coverage
- Build on_failure integration test graphs from DOT and share a run
harness, exercising the parser path for valid on_failure values

Use /tmp/fabro/runtime for both Docker and Daytona instead of
provider-specific roots. A writable /tmp inside the sandbox is already
a dependency (commit-message files, exec stop-files), it needs no
root-level mkdir for non-root container users, and it makes the two
providers uniform.
The trailing runtime path component stays load-bearing: materialized
blobs at runtime/blobs/{hash}.json are recognized as managed blob
references and normalized back to blob:// in durable context.

Remote prompt-value materialization wrote demoted values to
{working_directory}/.fabro/blobs inside the repository checkout, so a
later checkpoint could commit them and leak them into the run pull
request.
Give each sandbox a run-scoped runtime directory outside the source
checkout as part of the Sandbox contract:
- Sandbox::runtime_directory() names the directory; host-local
sandboxes return None because the engine owns a host-side runtime
directory (RunScratch) for those runs.
- Docker creates /fabro/runtime at initialize with umask 077 and
uploads runtime files with mode 0600.
- Daytona creates /home/daytona/fabro/runtime with mode 0700.
- Both remote materialization paths in fabro-workflow share one
materialization-path helper built on the new contract. The paths keep
the runtime/blobs suffix, so durable context still normalizes to
blob://sha256/... references.
- Local materialization now writes owner-private directories and files
on Unix.
Regression coverage: an integration test runs remote-style prompt
demotion against a real git checkout, then a real checkpoint commit,
and asserts the checkout stays clean, the agent-facing file is
readable, and a deleted materialized file is recreated from the
durable blob store. A real-Docker test verifies the runtime directory
and blob file permissions inside a container.

GET /repos/{owner}/{repo}/installation returns 404 both when the App is
not installed for the owner and when the installation's repository
selection excludes the repository. The single-repository mint path
reported only the first cause, which misleads users whose App is
installed but not scoped to the repository. Name both causes and the
repository in the error.

Drop the startup retirement of the auth/code keyspace instead of
carrying one-shot cleanup code forever. The records it deleted are
inert: at most a handful exist at cutover, every binary (old or new)
rejects them within 60 seconds of issue via the expiry check, and
nothing reads the keyspace after the move to SQLite. The refresh-token
retirement keeps its original inline shape.

Cleanup pass over the pending-CLI-authorization move to SQLite:
- Extract a shared Database::retire_keyspace helper; the refresh-token
and authorization-code retirements are now one-line wrappers over it.
- Inline the startup retirement call (dropping the single-use wrapper,
its context-chain test, and the test_close_slate hook it required)
and run both SlateDB retirement scans concurrently. Error policies
are unchanged: authorization codes fatal, refresh tokens best-effort.
- Add a shared sqlite_row module with typed identity/timestamp row
decoding, used by both AuthorizationCodeStore and AuthSessionStore;
the session store's stringly Error::Other corruption errors become
the typed InvalidStoredIdentity/InvalidStoredTimestamp variants.
- Delete Repository::gc, which had no production callers left and was
kept alive by its own test; update the record-layer docs to match.
- Deduplicate the SQLite test-support bootstrap into sqlite_test_pool,
reuse issue() in the invalid-timestamp test instead of a copied
INSERT, and fold the new table into the existing existence-check loop
in the fabro-db schema test.

- Use a derived deserializer for RunTarget by making `None` an empty struct
variant, which keeps `deny_unknown_fields` strict without a hand-rolled impl
- Make clone_source_for_run the single owner of the empty-workspace decision
and drop the duplicated target checks in RunSession::new
- Collapse duplicated target/provider compatibility matches in admission and
start into single matches, using a strum-derived kind name for messages
- Drop the redundant git override in persist_create_run
- Extract a shared helper for the duplicated unavailable-integration test loop

Keep VACUUM snapshots private until permissions and durability are established. Refuse to recreate a missing rollback backup after import has begun, and preserve secondary cleanup failures in startup logs.
The preflight demanded ~1.5x the full legacy inventory bytes free on
every startup, with no credit for rows already imported. Because the
first activation itself consumes about twice the legacy bytes (the
SQLite copy plus the retained backup) and the legacy keyspace stays in
place for the whole retention window, a successfully activated server
could fall below the requirement and become unable to restart until an
operator freed space the server would never write.
The legacy inventory now checks each row's hash against the SQLite blobs
table and reports pending rows and bytes, and the preflight requires
1.5x only the pending bytes plus the backup reserve and fixed headroom.
A warm restart with nothing left to import needs only the headroom.
Also updates the server operations doc for this and for the
verification pass now running only on boots that import rows.

Startup previously scanned the legacy SlateDB keyspace three times and
SHA-256-hashed every value in each pass (inventory, import,
verification), then read and rehashed every row of the live SQLite blobs
table — on every boot, even a warm restart with nothing to import. With
a large object-store-backed legacy keyspace that makes restart time
proportional to total blob bytes for the whole retention window.
The inventory pass now only validates key shapes and sizes the keyspace;
digests are still validated by the import pass before any row persists.
The independent verification sweep now runs only on boots whose import
actually inserted rows: the import pass itself byte-compares every
already-present legacy row each boot, so a no-op restart is already
fully cross-checked without a third scan or a full-table rehash.

import_legacy_blobs_into and verify_legacy_blobs_in took a &BlobStore and
extracted its pool through sqlite_pool_for_legacy_import, an Option that
was statically always Some in production (the None arm existed only for
the test-only Slate backend). That accessor forced a clippy
unnecessary_wraps suppression and two WrongTargetBackend error variants
no production caller could ever hit, and the activation path round-tripped
a pool it already owned through a BlobStore it had just built.
Both functions now take &SqlitePool, deleting the accessor, the
suppression, both unreachable variants, and their rejection test.

test_blob_store was a process-wide OnceLock singleton over one in-memory
SQLite connection, so content-addressed rows written by one test were
visible to every other test in the same process. nextest's
process-per-test model masked the bleed, but plain cargo test failed
(8/24 in fabro-workflow-version) because negative existence assertions
became order-dependent.
test_blob_store now builds a fresh isolated in-memory store per call,
and test_database gives every database its own blob authority.
Reopen-style tests that model one durable blob authority across several
store handles use the new test_blob_store_at, which keeps the blob table
in a SQLite file beside the store directory, plus
test_database_with_blobs to share it explicitly.

fabro-workflow's and fabro-server's src/test_support.rs import
fabro_store::test_support, but their test-support features never enabled
fabro-store/test-support. Workspace builds passed only through feature
unification from other members' dev-dependencies, while per-crate builds
such as `cargo check -p fabro-cli --tests` or
`cargo check -p fabro-server --features test-support` failed with E0432.

Blob activation cleanups:
- Reuse fabro-db's append_to_path, remove_file_if_exists, and
set_private_permissions instead of local duplicates.
- Return the store directly from activate_blob_storage; the report
wrapper existed only to be logged internally and then discarded.
- Collapse compute_disk_preflight to return the required free bytes
instead of echoing its inputs back through a struct.
- Deduplicate the "exactly one ok row" PRAGMA integrity_check protocol
into one executor-generic helper used by the backup and live checks.
- Skip re-validating a freshly published backup; the staging copy was
validated immediately before the atomic rename, so only a
concurrently published file needs its own validation.
- Replace the manual anyhow wrapping plus duplicate error log in
serve.rs with a plain .context(), matching other startup errors.
- Extract the disk-candidate enumeration in resource_sampler.rs that
available_space_for_path had copy-pasted from sample_disk_resources.
Test fixture cleanups:
- Route all hand-assembled Database::new(..., test_blob_store()) test
fixtures (32 sites) through fabro_store::test_support::test_database,
and make that helper infallible instead of returning an unconditional
Ok.
- Install the test blob schema from fabro_db::BLOBS_MIGRATION_SQL via a
test-support-gated optional dependency instead of a four-level
relative include_str! into fabro-db's migrations directory.

Apply cleanups from a reuse/simplification/efficiency review of the
bounded-tool-output changes:
- Share one MAX_RUN_EVENT_BODY_BYTES constant in fabro-types; the server
body limit, the agent's serialized-output reservation, and the event
headroom test all derive from it.
- Rework truncation.rs around one split_head_tail helper: drop the
hand-rolled ceil_char_boundary (std's is stable), the duplicate
truncate_plain_output splitter and its dead Tail arm, and the
head_bytes field with its sentinel values.
- Return Cow from preview_tool_output and take retain_tool_output's
input by value, so untruncated output crosses the pipeline without
full copies. Measure serialized JSON size with a counting writer
instead of materializing the payload.
- Reuse fabro-llm's byte-token estimate (now public) instead of a third
copy of the 4-bytes-per-token heuristic.
- Take retain_tool_result's ToolResult by value and mutate content in
place; extract the triplicated error retain-emit-truncate block into
finish_error_result.
- Share the shell retain-and-record sequence between the native and
kimi shell tools as retain_shell_output.
- Move OutputCaptureBuffer::into_parts to reuse the head allocation,
skip the buffer round-trip in replay_exec_result when output fits,
and replace daytona's byte-iterator suffix matching with contiguous
slice comparisons behind one retained_slices accessor.
- Make SessionBoundEmitter's fields private.

duration_to_minutes_i32 carried stacked docker and daytona cfg attributes,
which combine as AND, so building with the daytona feature alone failed to
find the function. fabro-workflow and fabro-cli enable daytona without
docker in their production dependencies, so that combination is real.
Removing the stray docker gate surfaced items that only docker-gated code
uses: the ResolveError import in from_environment and four exact-checkout
command builders in clone_source. Gate those on the docker feature, keeping
the command builders available to clone_source's own tests under cfg(test).

Cap closure expansion at 256 distinct workflow mounts. Mounts are keyed
by rebased path, so a small chain of stored versions that mounts a
shared dependency along two paths per level expands exponentially; a
single authenticated create request could stall the server before any
error was returned. The check also bounds the recursion depth.
Resolve file-form run goals through the certified version: expose
ValidatedWorkflowVersion::resolved_goal_file_content, which reuses the
exact grammar store validation certified, and drop the parallel
resolution (and its unreachable-for-stored-versions error variants) the
server had re-implemented. The certified entrypoint-presence invariant
replaces the MissingEntrypoint error the same way.
Destructure both environment layer types without `..` when pinning
server environment authority, so a new server-owned field becomes a
compile-time decision instead of silently escaping the pin.

Start reconciled the persisted target against its stored GitContext
projection field by field and failed the run on any drift, which forced
every RunSpec writer to keep the pair in lockstep forever. The target is
validated at admission and owns the grammar, so derive the clone source
from it alone; the projection stays persisted as display metadata that
can no longer fail an otherwise-healthy start.
Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
The Git-target grammar (slug, branch, and SHA rules plus the derived
origin URL) was implemented twice with no shared code path: once in
server admission and again in sandbox start, so the two could drift and
disagree about which persisted targets are valid.
Own it once as RunTarget::validate() in fabro-types, next to the
primitives it uses, returning the canonical target together with its
derived GitContext projection. Admission consumes it directly, and the
start path re-derives the expected clone source from the same rules
before checking the persisted projection against it. The start path now
also moves the derived strings into the sandbox spec instead of cloning
them.
While reordering admission around the shared validator, run the pure,
in-memory checks (target grammar, environment id) before the blob-store
closure fetch and lowering so malformed requests no longer pay for
version-store I/O.

Preserve the SQLite auth-session release notes alongside main's July 26 fixes and retain all current changelog navigation entries. Make the refresh-token rotation timestamp assertion deterministic after the merged suite exposed its wall-clock race.
Apply the cleanup findings from a four-angle review (reuse,
simplification, efficiency, altitude) of the demotion change:
- Share one size gate: serialized_if_over now backs both offload_value
and demote_value_for_prompt, restoring the cheap short-string and
scalar pre-checks so per-node demotion no longer serializes every
small value just to measure it.
- Stop re-writing blobs every node: materialize_value_bytes writes the
sandbox file directly from the in-hand bytes and short-circuits on the
content-addressed file's existence, so an already-demoted value costs
one existence probe instead of a store round-trip per node visit. The
local file write is shared with materialize_blob_ref.
- Demote over the resolved snapshot map instead of re-snapshotting a
Context copy, making the context and outcome loops symmetric and
saving a full deep clone per node; the fidelity lifecycle builds the
Context after the pass.
- Skip the pass entirely for Full and Truncate fidelities (nothing
renders context values), except parallel nodes whose branch stash may
render at a richer fidelity.
- Build is_preamble_hidden_key on is_engine_internal_key instead of
restating its prefixes, and call it directly from the preamble
renderer rather than through a wrapper.
- Document that outcome updates are demoted wholesale and that
BranchWorkItem.item carries the prompt-ready (possibly demoted) item;
drop the item rebinding and redundant test assertions; restore the
local integration test's confinement assertion and make the remote
one non-vacuous.
Skipped by choice: unifying the crate's several truncation helpers and
rendering the marker through the "See:" pointer family (cross-module
coupling out of proportion to the preview cosmetics), per-branch
demotion inside parallel.results (wholesale demotion is what bounds the
total), and cross-node demotion memoization (the file-existence
short-circuit already reduces repeats to a stat).

Compact and summary preambles render workflow context values and stage
outputs with no per-value size limit. A late-run node inherits everything
the run has accumulated, and one oversized value (a join result, a jobs
list, a single-line command emit) can push the composed prompt past the
model's context window. A security-review run failed exactly this way:
its dedupe stage assembled a ~1.8M-token prompt against a 1M-token model
limit, made almost entirely of accumulated context the agent never
needed inline.
Reuse the existing blob machinery at the last mile. Before the preamble
builders run, any resolved context or outcome value whose serialized
JSON exceeds 8KB is persisted as a content-addressed blob, materialized
as a real file in the sandbox, and replaced with a small marker holding
a preview, the byte count, and the file path. The agent reads the file
if it needs the data. for_each items get the same treatment at fan-out
with a more generous 64KB budget, since the item is the branch's work
assignment; branch labels still come from the full item. Keys the
preamble never renders are left alone, and a value that fails to demote
stays inline and is logged: demotion bounds prompt size, it does not
gate execution.
The two downstream-resolution integration tests asserted that resolving
text values writes no files; demotion now legitimately materializes the
oversized response for preamble use, so they instead pin that resolution
returned the full inline text and that nothing is written outside the
sandbox blob directory.

- Make the failure watch channel the single record of the latched
failure; drop the worker task's mirrored local state.
- Replace the hand-rolled wait loop with watch::Receiver::wait_for.
- Extract race_persistence/flush_or_stop helpers so the select!/flush
scaffolding in RunSession::run exists once instead of three times.
- Return RunEventPersistenceError from append_event_to_sink and add a
From impl on Error, replacing four hand-written per-event message
strings with the event name derived from the event itself.
- Dedupe the RunCreated test seed literal in initialize.rs and drop the
dead BlockingHandler::simulate override.
