fix: harden storage, mail, S3 and geocoding, and support binds= hosts - #63
Fixes the findings of a review of the codebase and releases them as 0.18.0. Each commit is one concern with its own tests and docs; the last one rewrites the 0.18.0 changelog entry as one release.
Security
Plain local storage on case- or normalization-folding filesystems (macOS, Windows).alice/Report.pdf and ALICE/report.PDF opened one file, so one key could read, overwrite or delete another's object. Keys are now matched against the names on disk exactly, in plain areas and in the legacy layout: a read of another spelling finds nothing, and a write or url() raises StorageKeyConflictError.
SMTP reply size.smtplib caps a reply line but not how many lines a reply has, and the greeting and first EHLO reply arrive before TLS. Each reply is now capped at 64 KiB.
S3 endpoint from the AWS configuration. An http:// endpoint set through AWS_ENDPOINT_URL[_S3] or the AWS config file skipped the cleartext check. It is now held to the same rule as one in the URI.
Cleartext geocoding through an environment proxy.+http requests no longer use HTTP_PROXY; https still uses the egress proxy.
Fixes
jasil.lifecycle.shutdown() no longer closes the platform under a handler that outlived the worker's stop timeout; stop_job_worker() returns whether a worker is still running (additive), and start_job_worker() raises instead of silently starting nothing while the old worker finishes.
MemoryState.incr refuses values outside the signed 64-bit range, as Redis does.
Event payload upgraders get a copy, so one that edits in place no longer changes what the event's other handlers read.
The rev0003 downgrade refuses up front when a host table holds an old unprefixed name, instead of failing part-way.
The rev0008 upgrade notes for MySQL/MariaDB said previous-release processes are unaffected; their audit maintenance is not. Corrected in the audit docs, the migration docstring and the changelog.
Feature
A session factory built with sessionmaker(binds=...) works (hosts with several databases): JASIL's statements, dialect checks and raw SQL go to the engine the rules give the mapped base, and get_engine() resolves it the same way. Before, every outbox, job and event-log write failed.
Housekeeping
Removed internal, test-only code: jasil.jobs.crud.enqueue_job, the job_ids parameter of the dead-letter delivery, and OUTCOMES.
Corrected drifted docs and comments (crud importability, signing_key validation timing, the rule count, the Redis extra name, the attempt outcomes).

Checklist
This PR is focused on a single concern
An issue was opened and acknowledged before writing this code (if not a small fix)
If this PR introduces a new feature during freeze, it was discussed and explicitly acknowledged first
The PR is under ~300 lines changed, excluding lock files, migrations, and generated code
Tests have been added or updated where applicable
Documentation has been updated where applicable
Commit messages follow Conventional Commits format
It spans several concerns and is about 930 added lines (about 520 of them tests), so it is split into one commit per concern for review. The binds= support was added without a prior issue.
Notes for the reviewer
Every bug fix started with a failing test. Each commit passes the full suite on its own.
Locally: ruff, format, import contracts, mypy, the suite (3768 passed; the 139 skipped need a real PostgreSQL or MySQL server), the per-module coverage floor, the docs-API check and mkdocs build --strict all pass. The PostgreSQL and MySQL paths, including SKIP LOCKED and the audit maintenance SQL under binds=, run only in the CI database jobs.
The storage aliasing tests run only where the filesystem folds names: they skip on Linux and run on the Windows job and on macOS.
binds= support was checked by running the whole suite once on a binds=-only session factory: hundreds of failures before the change, none from library code after. tests/test_session_binds.py keeps it covered with two engines and no default bind.
_MetadataOps.get_context() reports offline mode so schema derivation skips the new rev0003 pre-check: there is no database to inspect.
Untested: the 64 KiB cap after STARTTLS and over implicit TLS, and Windows trailing-dot or short-name aliases. Both follow from the code, not from a test.
With no endpoint_url in the URI, boto3 takes the endpoint from
AWS_ENDPOINT_URL, AWS_ENDPOINT_URL_S3 or the AWS config file, and an
http:// one to a public host was accepted unchecked. The endpoint the
client resolved is now held to the same rule as one in the URI.

requests took a proxy from HTTP_PROXY, so the +http forms sent the
coordinates unencrypted to a host the address check never saw. https
requests keep using the environment's egress proxy.

Every handler of an event type parses the same Event, so an upgrader
that edited its dict in place rewrote the payload the next one read.

Redis refuses a counter, amount or result outside int64; the memory
backend counted on past it, so the two backends diverged.

The downgrade renamed tables until it reached an unprefixed name a host
table already held, which on MySQL left it half done. It now checks
first. Schema derivation reports offline mode, as there is no database
to inspect.

When a handler outlived the stop's join timeout, shutdown() closed and
unpublished the platform under it, so the handler failed and used one
of its job's attempts; a later start_job_worker() then returned without
starting a worker, and none ran once the old thread exited.
shutdown() now leaves the platform up and logs a warning in that case,
stop_job_worker() reports whether a worker is still running, and
start_job_worker() raises while the old worker is still finishing.

A host with several databases routes engines with sessionmaker(binds=)
rather than one bind=. JASIL read session.bind, which such a session
lacks, so every outbox, job and event-log write failed and SKIP LOCKED
was silently off. Dialect checks, the idempotent insert and the audit
maintenance SQL now ask the session for the engine of JASIL's tables,
and get_engine() resolves it the same way.

Only tests called enqueue_job; the relay uses insert_job, whose
docstring now carries the contract. deliver_dead_letters and
claim_dead_letter_callbacks were never given job_ids outside tests, and
OUTCOMES was referenced only by a docstring. All are internal.

The crud modules are importable only after map_models; signing_key is
checked when the settings are built; there are six consistency rules;
the Redis extra is "redis"; and an attempt outcome can be "continued".

Walkthrough
Version 0.18.0 updates database bind routing, durable-job APIs and shutdown behavior, backend validation, event payload upgrades, and migration safeguards. The release also updates changelog, API, configuration, security, and backend documentation.
Changes: Database bind routing
Layer / File(s)
Summary
Resolve engines for mapped tables jasil/orm.py, tests/test_orm.py
get_engine() resolves the engine for JASIL tables through session routing, including binds= and connection-bound factories.
Route database operations by model jasil/_core/dialects.py, jasil/_core/pruning.py, jasil/jobs/crud.py, jasil/jobs/outbox.py, jasil/audit/maintenance.py, jasil/audit/service.py, docs/configuration.md, docs/api-stability.md
Dialect, lock, prune, and audit operations use binds for their mapped models. Documentation describes bind routing and the table-mapping requirement.
The enqueue_job wrapper and OUTCOMES tuple are removed. Dead-letter delivery no longer accepts job IDs and always applies the sweep window. Tests use insert_job and cover the updated claim behavior.
Worker stop reports success or timeout. A worker still finishing a handler cannot restart, and platform shutdown leaves the platform open until the worker stops.
Backend validation and storage safeguards
Layer / File(s)
Summary
Enforce state counter bounds jasil/backends/state_memory.py, tests/test_state_backends.py, docs/providers-and-backends.md
State increments reject stored values, amounts, or results outside the signed 64-bit range.
The upgrade guidance says to upgrade audit-maintenance processes alongside the partition revision and describes the documented effects of older processes.

Merge Risk: Low · previous review d431e
The release notes say there are no breaking changes and no upgrade steps. Deployments that use a public HTTP S3 endpoint from AWS configuration will now fail at startup, and code that restarts a job worker after a timed-out stop can now raise. Correct the changelog before release. A rare counter-overflow edge case in tiered failure counting is also worth fixing.

Full details: Title check
Explanation
The title names four areas: storage, mail, S3 and geocoding hardening, and binds= host support. The changeset covers these areas. Storage key matching, SMTP reply-size caps, S3 cleartext endpoint validation, and geocoding proxy handling all appear in the summaries. The sessionmaker binds= routing also appears across the ORM, dialects, jobs, and audit code. The title is somewhat broad and omits the job-worker shutdown, MemoryState.incr limits, and removal of enqueue_job changes. These are real parts of the change, so the title is partially related to the main change rather than unrelated.

If counter_key holds 2**63 - 1, record_tiered_failure writes 2**63. On the next call, the new _parse_integer check rejects that stored value. Redis instead refuses the increment without changing the counter. Check count against _INT64_MAX before the write, as incr does. (redis.io)

jasil/backends/storage_local.py: 1
249-261: Trivial · Performance & Scalability
Windows short-name and case-only aliases can pass the check when os.listdir(parent) is used on a non-existent-but-aliased component.
The loop calls os.path.lexists(current) before it lists the parent. On a folding filesystem, lexists returns true for an aliased spelling. The listing then lacks the requested name, and the check returns True. This is the intended behavior.
A race remains. Another process can create the differently spelled entry after the check and before the write. This is the same time-of-check and time-of-use limit that the threat model states for symlinks, so no code change is needed.
The check also costs one os.listdir per path component on every read, stat, exists, serve and delete in plain and legacy layouts. A parent directory with many entries makes each call linear in the entry count. Consider comparing with os.scandir or caching only if large flat areas are expected.

263-273: Trivial · Maintainability & Code Quality · Low value
Verify that get_engine() works when the base is mapped under binds= and the session is bound to a Connection.
The logic is plausible. _jasil_mapper() returns None before map_models. In that case session.get_bind() is called with no mapper. A factory that uses only binds= then raises UnboundExecutionError, and the code reports the "no engine" message. That message tells the host to pass a binds= rule that covers the base, but the real cause is that map_models has not run yet. This can mislead the host.
Consider adding a clause to the error message that says map_models must run first.

Windows resolves a path to the spelling on disk, so ALICE/report.PDF

now walks the area and key exactly as the caller spelled them.
