test: port the sep archive/link observers to ww; retire 989_{separchive,sepcycle_dup}
seplink_test.ww carries the .a substrate legs (root-as-.o layout, .a byte-id + 3x determinism, the #31 masked-dup PASS-3 reject with its non-vacuity flip), the loud dependency-cycle reject with byte-equal cs/ww stderr, and the w6l/w6l_ww bare-main duplicate-symbol reject (achievable substring parity per the filed message divergence).

/*
|
||||
* 989_separchive_run — M3-tail commit-5a gate (#46, task #62): the
|
||||
* per-package `.a` substrate + its archive-path #31 dup-detect, both
|
||||
* stages, COLD. Commit 5a makes `ww build` wrap each DEP package's
|
||||
* `.o` in a deterministic single-member `.a` (cstage archive_o /
|
||||
* wwstage archiveo) and link the ROOT as a positional `.o` (force-loaded)
|
||||
* + dep `.a` reverse-topo + libwwrt.a. The #31 dup the selective pull
|
||||
* would mask is caught by a post-pull PASS 3 in w6l/w6l_ww load_archive.
|
||||
*
|
||||
* Legs (fresh output stems under an invocation-owned root; retained
|
||||
* `<stem>.sepwork` is inspected, then removed by final carrier cleanup):
|
||||
* 1. POSITIVE: root→helper builds + runs exit 7, BOTH stages, through
|
||||
* the `.a` link path (root `.o` + helper `.a`).
|
||||
* 2. ★ DETERMINISM (ken, load-bearing): re-archive the same package 3×
|
||||
* → byte-identical `.a` (proves zeroed mtime/uid/gid + fixed mode +
|
||||
* fixed member name; a floating md5 would poison the 5b cache key).
|
||||
* 3. ★ cs `.a` == ww `.a` (rule 10, the NEW byte-id substrate ken binds):
|
||||
* the dep `.a` from `ww` is byte-identical to the one from
|
||||
* `ww_ww`.
|
||||
* 4. ★ #31 dup THROUGH the `.a` path (ken #263 + D3, the leg that proves
|
||||
* PASS 3 closed the selective-pull hole): two DEP packages each export
|
||||
* the same link symbol via `@symbol("dup_sym")`, referenced by root.
|
||||
* One dep's member is pulled; the OTHER lands UNPULLED and defines an
|
||||
* already-`defined` name — exactly what selective-pull skips. BOTH
|
||||
* stages must (exit≠0) ∧ (stderr contains "duplicate symbol") ∧ (no
|
||||
* partial binary). NON-VACUITY flip: give the second dep a DISTINCT
|
||||
* symbol → both stages build + run (exit 3), proving the leg actually
|
||||
* discriminates (without PASS 3 the dup leg would WRONGLY pass green).
|
||||
* 5. ACHIEVABLE-parity posture (same as c4's 989_sepcycle_dup, because
|
||||
* #61 is a separate commit): cs vs ww is `both exit≠0 ∧ both stderrs
|
||||
* contain "duplicate symbol"` — NOT exact-stderr-equal (cstage names
|
||||
* `<path>: duplicate symbol <sym>`, wwstage the bare form).
|
||||
*
|
||||
* Light wwstage-driver test (CLAUDE.md rule 14): all fixtures + scratch
|
||||
* live under /tmp, COLD each run. Models 989_sepbuild_run.c conventions.

* 989_sepcycle_dup — M3-tail commit-4 negative gates (#46, #31).
|
||||
*
|
||||
* Two error PATHS the commit-4 link-hardening relies on, each asserted to
|
||||
* ACTUALLY FIRE (ken #263: a happy-path-green run does not prove a reject
|
||||
* works — a no-op reject ships green). Every negative leg asserts
|
||||
* (exit != 0) AND (the expected stderr message) AND a non-vacuity flip
|
||||
* (remove the defect → green), so the gate cannot pass for the wrong
|
||||
* reason.
|
||||
*
|
||||
* A. LOUD dep-cycle reject (spec §2, Hare deps.ha:243). A 3-package
|
||||
* import cycle root->A->B->C->A fed to `ww build` must exit
|
||||
* non-zero, print the `dependency cycle: A -> B -> C -> A` chain, and
|
||||
* produce NO output binary. cs==ww (rule 10): the cycle message is
|
||||
* pure driver code, so cstage `ww` and wwstage `ww_ww` emit
|
||||
* BYTE-IDENTICAL stderr — asserted here. Non-vacuity: break the cycle
|
||||
* (C stops importing A) → both stages build green and the program
|
||||
* runs (exit 7).
|
||||
*
|
||||
* B. #31 duplicate-symbol reject (spec §3; w6l ALREADY detects it, this
|
||||
* gate only proves it fires). Two trivial root units each define a
|
||||
* bare `main` (the #31 bare-collision class — #53 path-qualifies
|
||||
* normal exports, so `main` is the cleanest bare clash); both `.o`
|
||||
* fed directly to `w6l` AND `w6l_ww` must exit non-zero with a
|
||||
* `duplicate symbol` message. Non-vacuity: link a single `.o`
|
||||
* (+ libwwrt.a) → clean link, runs.
|
||||
* NOTE on parity: w6l and w6l_ww BOTH reject loud + non-zero and both
|
||||
* name "duplicate symbol", but the EXACT text differs — cstage adds
|
||||
* the path+symbol (`w6l: u2.o: duplicate symbol main`), wwstage prints
|
||||
* the bare `w6l: duplicate symbol`. That is a PRE-EXISTING w6l_ww vs
|
||||
* w6l message divergence on the reject path (byte-id-blind); commit 4
|
||||
* adds NO linker code and must hold w6l_ww byte-identical, so it is
|
||||
* NOT reconciled here. The gate asserts the achievable reject parity:
|
||||
* both exit != 0 AND both stderr contain "duplicate symbol". The
|
||||
* text-divergence is filed (see report) for a sibling linker task.
|
||||
*
|
||||
* Light wwstage-driver test (CLAUDE.md rule 14): all fixtures + scratch
|
||||
* live under /tmp, COLD each run. Models 989_sepbuild_run.c conventions.
