Subject: [PATCH] jenner-check: add 5 Jenner compatibility bundles + runner

Adds a self-contained jenner-check/ directory with five bundles derived from
this library's own macros and format programs:
  t001_chas_stattest      - %chas_stattest two-estimate significance test
  t002_reshape_chas       - %reshape_chas varlist -> positional c1..cN
  t003_sec8mf_addr_correct- %Sec8MF_addr_correct SELECT/WHEN address fixups
  t004_sec8mf_formats     - Sec8MF_formats.sas PROC FORMAT catalog
  t005_lihtc_formats      - Make_formats_lihtc.sas PROC FORMAT catalog

Each bundle ships a copy of the program, a small mock input standing in for
the site data set it reads, the captured log and listing, and pinned
expected.json fields. A shell runner (run_jenner.sh) re-runs every bundle
against api.jenneranalytics.com and checks the pinned fields. Nothing outside
jenner-check/ is touched and nothing runs on merge.

+# jenner-check: compatibility test bundles
+
+Each `tNNN_<slug>/` subdirectory is a self-contained test bundle built from SAS
+code that already lives in this repository. A bundle pins the output of a
+captured passing run so the same script can be re-run later and compared
+against that snapshot.
+
+This directory is fully self-contained: nothing outside `jenner-check/` is
+referenced or modified, nothing runs on merge or checkout, and deleting the
+directory removes every trace of it.
+
+## What the runner sends — read before running
+
+`run_jenner.sh` uploads only a bundle's SAS **source text** — `autoexec.sas`
+plus `script.sas`, and nothing else — over HTTPS to `api.jenneranalytics.com`,
+where it runs and returns the log and listing. It does not read or upload any
+data files, so anything sitting next to a script stays on your machine; the
+only thing transmitted is the code you run, as when pasting a snippet into any
+hosted tool. Nothing is sent unless you run a command yourself. To point the
+runner at a different endpoint, set `JENNER_HOST`.
+
+## What's in here
+
+```
+jenner-check/
+├── README.md            # this file
+├── run_jenner.sh        # runner (bash + curl; python3 used if present)
+└── tNNN_<slug>/
+    ├── script.sas       # the SAS under test (derived from this repo)
+    ├── autoexec.sas     # run options prepended to script.sas at run time
+    ├── expected.json    # fields pinned from the captured passing run
+    ├── meta.json        # provenance: source file, blob sha, commit
+    └── expected/        # human-readable snapshot of that run
+        ├── log.txt
+        └── output.txt
+```
+
+`meta.json` records the source path, blob sha, and commit of the script each
+bundle was built from, so you can verify the copy matches your code.
+
+## How to run
+
+From inside this directory:
+
+```bash
+./run_jenner.sh --list             # show the bundles in this directory
+./run_jenner.sh --all              # run every bundle, verify pinned fields
+./run_jenner.sh tNNN_<slug>        # run just one (use a name from --list)
+```
+
+For each bundle the runner submits the SAS, writes the JSON response to
+`<bundle>_response.json`, and compares the response against the bundle's
+`expected.json` — status, exit code, and the pinned log lines. A bundle
+passes only when every pinned field matches, so an `N pass, 0 fail` summary
+from `--all` means the captured results still hold.
+
+You can also compare a saved response offline, with no network call:
+
+```bash
+./run_jenner.sh --compare tNNN_<slug>_response.json tNNN_<slug>/expected.json
+```
+
+Requirements: `bash` 4+ and `curl` (both ship with mainstream Linux and
+macOS); `python3` for the pinned-field comparison. On Windows, run it under
+WSL.
+
+## Removing this directory
+
+`git rm -r jenner-check/` (or just delete the folder). Nothing else in the
+repository references it.
+
+---
+
+`run_jenner.sh` and this README are provided under the MIT license. Each
+bundle's `script.sas` is a copy of code that already lives in this repository
+and remains under this repository's own license — nothing here relicenses it.

+#   ./run_jenner.sh t001_something   # run that one

+#
+#   (no arg)     If the current directory has tNNN_* bundles, list them

+#                exit without running anything.
+#
+#   --compare    Purely local, no network: check RESPONSE.json against the
+#                pinned EXPECTED.json and print one line per check. Only
+#                keys present in EXPECTED.json are checked (keys starting
+#                with "_" are provenance and ignored): status / exit_code
+#                must match exactly, every log_contains entry must appear
+#                in the response log, no log_does_not_contain entry may
+#                appear, output_contains entries must appear in the output,
+#                and pinned diagnostics lists must match exactly. Unknown
+#                keys print a warning and do not fail.
+#                Exit 0 all-match, 1 any mismatch, 2 usage/unreadable file/
+#                invalid JSON, 5 python3 unavailable.
+#
+#   bundle-dir   A directory containing script.sas and (optionally)
+#                autoexec.sas. The two are concatenated (autoexec first,
+#                then a blank line, then script) and submitted together.
+#                This is the normal case.
+#
+#   script.sas   A single .sas file. Submitted as-is — no autoexec.
+#
+# The API response is written to <response.json> (or response.json in
+# the current directory if omitted) and the most useful fields are also
+# printed to stdout for a quick sanity check.
+#
+# What "pass" means: a bundle run passes only if the POST returns HTTP 200
+# AND — when the bundle carries an expected.json and python3 is available —
+# the fresh response matches every pinned field (the --compare semantics
+# above). Without python3 the pinned comparison is skipped with a notice
+# and the run falls back to the old HTTP/status-only behavior.
+#
+# Requires: bash 4+, curl. Both ship with every mainstream Linux distro
+# and macOS 12+. python3 (present on virtually every modern system) is
+# optional but needed for the pinned-result comparison and the pretty
+# summary. Windows: use run_jenner.bat (single-file mode) or WSL.
+#
+# IMPORTANT: execute this script, don't source it. Running with `. ./...`
+# or `source ./...` will short-circuit error handling and can close your
+# terminal if an error path fires.

+ The %Sec8MF_addr_correct macro is reproduced verbatim from the
+ repository. It is an autocall macro that Sec8MF_dmvw.sas drops inside a
+ DATA step to fix a handful of known-bad HUD Section 8 multifamily street
+ addresses (DC only), using a SELECT ( address_line1_text ) block. Here we
+ supply a small mock contract table exercising both corrected addresses,
+ a DC address that should pass through unchanged, and a non-DC row (so the
+ outer "if state_code = 'DC'" guard is exercised too), then invoke the
+ macro inside a DATA step exactly as Sec8MF_dmvw does.

These mix plain numeric maps with SAS special-missing keys (.n, .u, .c) and one character format. Only change vs upstream: format library HUD -> WORK so the run is self-contained; the PROC CATALOG entrytype-modify block follows to WORK.Formats. Added a small DATA step applying lihtc_reg, lihtc_credit, lihtc_inc_ceil and $lihtc_record_stat via PUT so the listing shows them resolving. Exercises PROC FORMAT numeric + character VALUE ranges, PROC CATALOG modify + CONTENTS, and PUT-based format application."

+ The PROC FORMAT value definitions for the HUD LIHTC data sets are
+ reproduced verbatim from the repository. The only change from upstream is
+ the format library target: HUD becomes WORK so the run is self-contained.
+ These formats mix plain numeric maps with SAS special-missing keys (.n,
+ .u, .c) and one character format. After building the catalog we apply a
+ couple of the formats via PUT so the listing shows them resolving.
