Clicking a history snapshot in the tree 404'd: the dispatcher's dot-prefix
guard blocks every .-segment URL, and the preview fetch hit the raw
.history/<stem>/<snap>.md path. But .history is ACL-modeled content (it
inherits the shadowed file's .zddc chain), not infra like .devshell — so
the guard was redundant with permissions there.
Carve GET/HEAD of .history out of the dot-prefix guard: snapshots are now
fetchable as ordinary ACL-gated files (read the live file → read its
history). Writes into .history stay blocked, and the listing dot-filter
still hides it from default views unless ?hidden is set. Export
handler.HistoryDirName for the dispatcher.

Redesign the markdown edit-history store from content-hashed blobs +
log.jsonl to one self-describing file per save:
.history/<stem>/<ts>-<email>.<ext>
The filename IS the audit (colon-free UTC timestamp valid on SMB/Azure
Files + the authoring email); listing the directory is the history. No
sidecar log, no hashing. A byte-identical save is a no-op; a pre-existing
file lazy-seeds its current bytes (author "unknown", stamped at mtime).
Reverting copies an old snapshot back (records as a fresh save). Snapshots
are kept forever.
Fixes the 404 reading history: reads no longer require history to be
*currently* enabled — ServeTextHistory serves whatever .history/<stem>/
exists (empty list when none); the dispatch drops the EffectiveHistory
gate for reads. WRITES stay gated by the history: flag. (The 404 came from
the aggregator refactor turning history off on project-level working/,
which made already-recorded snapshots unreadable.)
Renames: an in-place rename carries .history/<stem>/ to the new name
(serveFileMove); a cross-dir move leaves it behind.
Defaults: history: true now ships on the three live-editing slots —
working, mdl, rsk — at both the project-level nodes and the per-party
folders. It's a .zddc cascade key, so operators override per project.
Records (.yaml in mdl/rsk) keep their separate record-history path.
Browse history viewer updated to the filename-based version id (id ←
sha). Tests rewritten for the per-file scheme + rename behavior + SMB-safe
names; HistoryAt defaults test updated.

A history: true .zddc subtree (enabled by default on archive/<party>/working/)
routes markdown PUTs through WriteTextWithHistory: each save snapshots the
content into a hidden, immutable .history/<stem>/ store (content-addressed
blobs + an append-only log.jsonl carrying server-stamped {ts, email, sha,
prev}) before writing the live file. The live file at its natural path stays
the source of truth; no symlinks, no audit in the body/filename.
Reads: GET <file>?history=1 lists versions (newest-first, current flagged);
GET <file>?history=<sha> returns that version's bytes (hex-id guard against
traversal). Listings carry a per-file History flag so the browse client knows
where to offer the affordance.
History is subtree-inheriting and ignores inherit:false ACL fences (versioning
is a write behavior, not a permission), so fenced per-user homes under working/
are covered too. No-op saves dedup; pre-existing files lazy-seed their origin
version. Records (.yaml) keep their existing in-body-audit history path.

The in-dir form create/update (serveFormCreate/serveFormUpdate) wrote
records with plain WriteAtomic + date+email naming — no audit stamping,
no filename composition, no field_codes/folder_fields. So "+ Add row"
from a per-party mdl/rsk table produced un-stamped, mis-named rows that
the tables tool's own PUT-update path (which composes) would then 422
on. Only PUT and the project rollup honored the record machinery.
Now every record-write entry point converges on WriteWithHistory:
- Extract the shared field_defaults + folder_fields + row-assign +
compose step into recordCreatePrep (history.go); the rollup uses it
too, replacing its inline copy.
- serveFormCreate: when a records: rule with a filename_format applies
in the target dir, compose the name + route through WriteWithHistory;
otherwise keep the generic date+email submission write.
- serveFormUpdate: route through WriteWithHistory unconditionally — it
stamps/historizes records and plain-writes non-records. Editing a
tracking-number component in place now 422s (identity is the
filename; renames are delete+create).
- Drop originator from required: in the per-party mdl/rsk forms and mark
it readOnly, matching the rollup forms — it's server-derived from the
party folder, so a create needn't send it.
Docs (AGENTS.md, ARCHITECTURE.md) updated for the converged wire
surface. Tests: in-dir record create composes + stamps audit +
folder-binds originator; in-dir update bumps revision and rejects an
in-place component edit.

Two coupled cleanups so the baked-in defaults reflect the actual
convention instead of leaking one project's choices into every
deployment:
- Drop the project-wide phase/area components from the default
filename_format, form schemas, and table columns. They must be
all-on or all-off across a project to keep filenames lexically
consistent, so the simplest default omits them; operators re-enable
via the commented-out templates + a .zddc filename_format override.
Teaching comments (incl. a field_codes: example) now ride along in
defaults.zddc.yaml, which `show-defaults` dumps verbatim.
- Separate suffix from sequence with a template hyphen
({sequence}-{suffix?}); stored suffix is now just the part marker
(A, 01) with no leading dash.
- New records: key `folder_fields: {field: parent-distance}` binds a
body field to an ancestor folder name. The default mdl/rsk records
bind originator to the party folder (distance 1) — the folder is the
sole source of truth. The server overwrites the body value before
validation + composition (WriteWithHistory and the rollup create
path), and the form renderer marks the field read-only and pre-fills
it. Rollup forms drop originator from required (server derives it
from the selected party).
Tests: folder-binding overwrite + wrong-originator-filename 422, and a
form-render readOnly/prefill assertion; existing record tests realigned
so the party folder name equals the originator.

Adds history_test.go with eight cases exercising the record-write
orchestration path:
- CreateStampsAuditFields: PUT to a fresh mdl path → audit fields
injected; response echoes the stamped YAML; no history dir yet.
- UpdateIncrementsRevisionAndArchivesPrior: second PUT archives
the prior bytes under .history/<base>/<ts>-<sha8>.yaml, bumps
revision, preserves created_*, chains previous_sha.
- ConflictPreservesHistory: 412 from stale If-Match leaves the live
file untouched and writes NO history entry (the failed write must
be a true no-op).
- ClientAuditFieldsStripped: client-supplied created_by / revision
are silently overwritten by server values — anti-forgery test.
- FilenameMismatch: URL says ...-0002 but body composes to ...-0001
→ 422.
- LockedFieldRejected: posting type=SPC to an rsk row → 422 with
/type error (rsk/ locks type=RSK via cascade).
- SSRHistoryAtPartyLevel: writes to archive/<party>/ssr.yaml put
history at archive/<party>/.history/ssr/, NOT at
archive/.history/<party>/.
- RollupCreate_AssignsRowAndComposesFilename: three POSTs to
/project/rsk/form.html in two table-scope groups demonstrate the
server picks up filename_format + row_field+row_scope_fields from
the cascade, auto-assigns sequence row numbers per group, and
composes the canonical filename.
Bug fix surfaced by the first test: composeFilename was eliding TWO
separators around an optional placeholder when one was correct.
"ACM-{phase?}-PRJ" with phase="" was producing "ACMPRJ" instead of
"ACM-PRJ". Now drops only the trailing separator from output and
lets the next iteration emit the connector.
Default-project-{mdl,rsk}.form.yaml updated: project-rollup MDL +
RSK schemas gained the six readOnly audit fields and the project-
rsk schema picked up the full table-tracking component shape (+
row) plus an enum-locked type=RSK. The required: list no longer
includes type for rsk schemas — the cascade's field_defaults
injects it after schema validation, and requiring it would 422
well-behaved clients.

Two extension fields added to jsonschema.Schema so server-injected
constraints survive the YAML→Schema→JSON round-trip:
- Pattern: regex hint for the form renderer (server-side validation
for field_codes already runs via WriteWithHistory).
- ReadOnly: surfaces locked / audit fields as disabled in the UI.
- Labels: x-labels extension carrying human-readable display strings
paired with enum keys (e.g. ACM → "Acme Inc"), so dropdowns can show
"ACM — Acme Inc" rather than bare codes.
serveFormRender now calls augmentSchemaFromCascade after loading the
spec: per-field, it injects enum (from field_codes:codes), pattern
(from field_codes:pattern), readOnly (from records:locked), and
default (from records:field_defaults). The augmentation is
per-request and never touches the on-disk *.form.yaml — operators
who declare their own enum/pattern in the spec take precedence
(injection is "if absent").

Adds cascade-driven schema + immutable audit history for the three table-style
record stores (mdl, rsk, ssr). Two new .zddc top-level keys carry the rules:
- field_codes: discriminated-union vocabulary (kind: enum|pattern|free) for
the components used to compose tracking-number filenames and constrain
record bodies. Map-merge across the cascade, mirror of apps: semantics.
- records: per-pattern rules (filename_format, field_defaults, locked,
row_field, row_scope_fields). Filename-pattern scoping lets the SSR rule
live at the party-folder level without bleeding onto mdl/rsk siblings.
PUTs to record YAML files route through a new WriteWithHistory orchestrator
(internal/handler/history.go) which:
- strips six client-supplied audit fields (created_at/by, updated_at/by,
revision, previous_sha) so the client can't forge them
- validates body values against the cascade-resolved field_codes
- enforces filename_format composition (URL basename must match body fields)
- checks locked: defaults (422 mismatch)
- archives prior bytes to <dir>/.history/<base>/<RFC3339Nano>-<sha8>.<ext>
- stamps server-managed audit fields and writes the live file
History-before-live ordering preserves the prior version even on mid-write
crash. previous_sha forms a hash chain across revisions for tamper evidence.
The embedded defaults.zddc.yaml now declares records: entries for mdl, rsk,
and ssr.yaml. RSK rows carry the table-tracking components + row sequence
(filename = <table-tracking>-<row>); MDL rows compose to their own
tracking number; SSR records' identity is the party folder name.
GET <record>.yaml?history=1 returns a JSON list of prior revisions, ACL
gated identically to the live record. dot-segment rejection in
resolveTargetPath protects .history/ from direct client writes.
