Closes #10050

What

t27c gen-json <spec> prints the IGLA board event a spec states, as one compact JSON object:

{"job":JOB,"stage":STAGE,"msg":MSG,"progress":PROGRESS,
 "metrics":{KEY_LENS:LENS_PCT,KEY_CELLS:[{KEY_STATUS:CELL_STATUS[c],KEY_PCT:CELL_PCT[c]} ...]}}
  • Values (FR-001). Every value comes from the spec through the gen-js value layer, codegen_js::const_value(&JS, ...). That layer already spells strings, numbers and arrays as valid JSON, so no value is written in Rust.
  • Keys. The keys inside metrics come from the spec's KEY_* consts.
  • Cells. The 27 cells are made by zipping CELL_STATUS with CELL_PCT. If the two arrays differ in length, the command stops with an error.
  • Missing const. The command exits non-zero and names it, for example gen-json: the spec declares no const KEY_PCT.
  • Not committed (FR-003, changed 2026-10-18). The event is not committed under gen/; whatever posts it runs t27c gen-json at post time.
    • The copy committed earlier went stale every time the map moved: 621, then 622, then 626 bytes within a day.
    • The L2 GENERATION rule also refused gen/json/ as a backend directory it does not know.
    • The spec stays the event's only home. The issue was edited to match.

Foreign-code gate

This adds Rust under bootstrap/. The owner approved the label on 2026-10-18 and named the offset (translated from chat): "the label is approved; for the offset, delete docs/reports/data/W564-harness.sh and tools/jtag/read_user1.py, and keep the glue to 46 lines or fewer".

lines
hand-written Rust added (bootstrap/src/main.rs only: subcommand, 2 dispatch arms, run_gen_json) +30
docs/reports/data/W564-harness.sh deleted -26
tools/jtag/read_user1.py deleted (already ported as specs/port/tools/jtag/read_user1.t27) -20
net hand-written foreign code -16
  • tools/devhome_baseline.txt drops the deleted harness's line. It is modified, not deleted.
  • foreign-budget and own-language pass in lefthook, on both pre-commit and pre-push.

The metrics object is 626 bytes, equal to master's METRICS_BYTES.

An earlier run (before the drop commit) included a negative control: with KEY_PCT removed from a copy of the spec, the command printed Error: gen-json: the spec declares no const KEY_PCT and exited 1.

The igla-judge Railway cron that POSTs this body to board.railway.internal:8081/event is the next step. It is config-only and is not part of this PR.

fb7d9b4 
…bject (Closes #10050)

t27c gen-json reuses the gen-js value layer (const_value through the JS
Target) and arranges the values into the board's event
{job, stage, msg, progress, metrics}, the metrics keys taken from the
spec's KEY_LENS/KEY_CELLS/KEY_STATUS/KEY_PCT and the 27 cells zipped from
CELL_STATUS and CELL_PCT.

Hand-written Rust: +30 lines, all in bootstrap/src/main.rs (already on the
owner's exception list; a new file would need a protected list change).
Offset named by the owner: docs/reports/data/W564-harness.sh (-26) and
tools/jtag/read_user1.py (-20, already ported as
specs/port/tools/jtag/read_user1.t27); the devhome baseline drops the
deleted harness's line.

…irectory (Closes #10079)

BACKENDS and SUBCOMMANDS gain the pair json / gen-json at index 4,
pinned by the_backend_table_is_pinned. A gen/json/<stem>.json copy is
then checked like every other copy: t27c gen-json specs/<stem>.t27 must
reproduce it byte for byte. gen/jsonl/ stays an unknown backend.

The L2 check runs the base's copy of this rule, so #10064 (gen-json,
#10050) needs this entry on master before its committed
gen/json/igla/own_model_board.json can pass.

gen/c/policy/l2_generation.c is t27c gen-c output from the Railway lab
(sha256 5d625a4c...33d1, 42175 bytes); test report 22/22, 0 vacuous.

Status of the PR-specific reds on d5af744:

  • L2 GENERATION (HAND-MADE COPY gen/json/igla/own_model_board.json: a backend directory t27c does not write): the check runs master's copy of l2_generation.c, whose backend table has no json. spec(policy): l2_generation -- gen/json/ is t27c gen-json's backend directory (Closes #10079) #10082 adds json -> gen-json; on the lab, gen-c output is byte-identical and the spec passes 22/22. Once spec(policy): l2_generation -- gen/json/ is t27c gen-json's backend directory (Closes #10079) #10082 is on master, re-run this check. It will then compare the JSON with t27c gen-json specs/igla/own_model_board.t27.
  • fpga-conformance: the elab ratchet reports NEW modules openxc7_dsp_fabric, wasm_board_ax7203 and wasm_interp. All three come from master, and master's own runs of that workflow fail the same way. This PR touches nothing under fpga/.
  • Deletions: docs/reports/data/W564-harness.sh (-26) and tools/jtag/read_user1.py (-20) are the foreign-code offset the owner named. tools/devhome_baseline.txt is modified, not deleted: it only drops the deleted harness's line.

* seal(policy): reseal l2_generation after the json backend entry (Refs #10079)

spec-guards and coverage reported the seal stale: the spec changed in
the previous commit. Resealed on the Railway lab with
t27c seal specs/policy/l2_generation.t27 --save (zig 0.16.0): 22/22
pass, and the four gen hashes equal the "current" values CI printed
(c 9bde97a5, rust 1381dab7, verilog c8b31e83, zig 1b937eda).

gen(json): drop the committed board event; t27c gen-json prints it at…
9243cbf 
… post time (Refs #10050)

The committed gen/json/igla/own_model_board.json went stale the moment
master's map moved (622 bytes / 42% committed, master now states its own
METRICS_BYTES and percentage), and every REVIEWED flip would move it
again. It was a second home for what own_model_board.t27 already
states, and the L2 rule refused it as a copy in a backend directory it
does not know. The event is produced when it is posted, by
t27c gen-json specs/igla/own_model_board.t27, and is never committed.
