 # timeago Shared Display Implementation Plan
 > **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.
 **Goal:** Unify all user-facing datetime rendering in `l4d2web` behind a single `timeago` Jinja filter that returns a `<time>` element with a relative label and a precise UTC tooltip.
 **Architecture:** Two callables in `l4d2web/l4d2web/services/timeago.py` — `humanize_delta` (pure text, source of truth for the relative-label ladder) and `format_time_html` (wraps the text in a `<time>` element). The latter is registered as Jinja filter `timeago` in the Flask app factory. Templates and routes migrate from raw datetime repr and bespoke inline math to `{{ ts | timeago }}`.
 **Tech Stack:** Python 3.13, Flask, Jinja2, `markupsafe.Markup`, pytest.
 **Reference spec:** `docs/superpowers/specs/2026-05-16-timeago-shared-display-design.md`

 ## Task 1: Rewrite `humanize_delta` with the new ladder
 **Files:**
 - Modify: `l4d2web/l4d2web/services/timeago.py`
 - Create: `l4d2web/tests/test_timeago.py`
 The current ladder uses `just now` under 45s and clamps future deltas. The new ladder is symmetric, has second precision, and uses day-month (with year if different) for ≥7 days. Spec table in section "Ladder (long form, symmetric for past and future)".
 - [ ] **Step 1: Create the test file with parameterised boundary tests**
 Create `l4d2web/tests/test_timeago.py` with:
 ```python
 from datetime import UTC, datetime, timedelta
 import pytest
 from l4d2web.services.timeago import humanize_delta
 NOW = datetime(2026, 5, 16, 12, 0, 0, tzinfo=UTC)
@pytest.mark.parametrize(
    ("delta", "expected"),
    [
        # zero
        (timedelta(0), "now"),
        # past, seconds
        (timedelta(seconds=1), "1 second ago"),
        (timedelta(seconds=2), "2 seconds ago"),
        (timedelta(seconds=59), "59 seconds ago"),
        # past, minutes
        (timedelta(seconds=60), "1 minute ago"),
        (timedelta(minutes=1), "1 minute ago"),
        (timedelta(minutes=2), "2 minutes ago"),
        (timedelta(minutes=59), "59 minutes ago"),
        # past, hours
        (timedelta(minutes=60), "1 hour ago"),
        (timedelta(hours=1), "1 hour ago"),
        (timedelta(hours=2), "2 hours ago"),
        (timedelta(hours=23), "23 hours ago"),
        # past, days
        (timedelta(hours=24), "1 day ago"),
        (timedelta(days=1), "1 day ago"),
        (timedelta(days=2), "2 days ago"),
        (timedelta(days=6), "6 days ago"),
        # past, date fallback same year (now = 16 May 2026)
        (timedelta(days=7), "9 May"),
        (timedelta(days=30), "16 Apr"),
        (timedelta(days=120), "16 Jan"),
        # past, date fallback different year
        (timedelta(days=365), "16 May 2025"),
        (timedelta(days=400), "11 Apr 2025"),
    ],
 )
 def test_humanize_delta_past(delta, expected):
    then = NOW - delta
    assert humanize_delta(then, now=NOW) == expected
@pytest.mark.parametrize(
    ("delta", "expected"),
    [
        # future, seconds
        (timedelta(seconds=1), "in 1 second"),
        (timedelta(seconds=2), "in 2 seconds"),
        (timedelta(seconds=59), "in 59 seconds"),
        # future, minutes
        (timedelta(seconds=60), "in 1 minute"),
        (timedelta(minutes=2), "in 2 minutes"),
        (timedelta(minutes=59), "in 59 minutes"),
        # future, hours
        (timedelta(hours=1), "in 1 hour"),
        (timedelta(hours=23), "in 23 hours"),
        # future, days
        (timedelta(days=1), "in 1 day"),
        (timedelta(days=6), "in 6 days"),
        # future, date fallback same year
        (timedelta(days=7), "23 May"),
        (timedelta(days=30), "15 Jun"),
        # future, date fallback different year
        (timedelta(days=365), "16 May 2027"),
    ],
 )
 def test_humanize_delta_future(delta, expected):
    then = NOW + delta
    assert humanize_delta(then, now=NOW) == expected
 def test_humanize_delta_accepts_naive_input_as_utc():
    then_naive = (NOW - timedelta(minutes=5)).replace(tzinfo=None)
    assert humanize_delta(then_naive, now=NOW) == "5 minutes ago"
 def test_humanize_delta_accepts_naive_now_as_utc():
    then = NOW - timedelta(minutes=5)
    now_naive = NOW.replace(tzinfo=None)
    assert humanize_delta(then, now=now_naive) == "5 minutes ago"
 def test_humanize_delta_default_now_is_datetime_now_utc():
    then = datetime.now(UTC) - timedelta(seconds=3)
    assert humanize_delta(then) in {"3 seconds ago", "2 seconds ago", "4 seconds ago"}
 def test_humanize_delta_year_boundary_includes_year_when_years_differ():
    now = datetime(2026, 1, 2, 12, 0, 0, tzinfo=UTC)
    then = datetime(2025, 12, 30, 12, 0, 0, tzinfo=UTC)
    assert humanize_delta(then, now=now) == "30 Dec 2025"
 ```
 - [ ] **Step 2: Run the new tests to verify they fail against the current implementation**
 Run: `pytest l4d2web/tests/test_timeago.py -v`
 Expected: most past tests FAIL (current implementation returns `just now` under 45s, no singular `1 second ago`); all future tests FAIL (current clamps to 0 → `just now`); date-fallback tests FAIL (current returns ISO `2025-04-21` not `9 May`).
 - [ ] **Step 3: Rewrite `humanize_delta` to satisfy the tests**
 Replace the entire contents of `l4d2web/l4d2web/services/timeago.py` with:
 ```python
 from datetime import UTC, datetime
 _MONTHS = (
    "Jan", "Feb", "Mar", "Apr", "May", "Jun",
    "Jul", "Aug", "Sep", "Oct", "Nov", "Dec",
 )
 def _ensure_utc(dt: datetime) -> datetime:
    if dt.tzinfo is None:
        return dt.replace(tzinfo=UTC)
    return dt
 def _format_date(then: datetime, now: datetime) -> str:
    month = _MONTHS[then.month - 1]
    if then.year == now.year:
        return f"{then.day} {month}"
    return f"{then.day} {month} {then.year}"
 def _relative_label(seconds: int, past: bool) -> str:
    if seconds < 60:
        unit, n = "second", seconds
    elif seconds < 3600:
        unit, n = "minute", seconds // 60
    elif seconds < 86400:
        unit, n = "hour", seconds // 3600
    else:
        unit, n = "day", seconds // 86400
    plural = "" if n == 1 else "s"
    if past:
        return f"{n} {unit}{plural} ago"
    return f"in {n} {unit}{plural}"
 def humanize_delta(then: datetime, now: datetime | None = None) -> str:
    if now is None:
        now = datetime.now(UTC)
    then = _ensure_utc(then)
    now = _ensure_utc(now)
    delta_seconds = int((now - then).total_seconds())
    abs_seconds = abs(delta_seconds)
    if abs_seconds == 0:
        return "now"
    if abs_seconds >= 7 * 86400:
        return _format_date(then, now)
    return _relative_label(abs_seconds, past=(delta_seconds > 0))
 ```
 - [ ] **Step 4: Run the tests to verify they pass**
 Run: `pytest l4d2web/tests/test_timeago.py -v`
 Expected: all tests PASS.
 - [ ] **Step 5: Run the full test suite to check for regressions in callers of `humanize_delta`**
 Run: `pytest l4d2web/tests -q`
 Expected: all tests pass. If any pre-existing test asserts on the legacy "just now" / 7-day ISO fallback strings via `latest_job_when` rendering, update those assertions to match the new format (e.g. "1 second ago", "9 May"). Note in commit message which tests were updated and why.
 - [ ] **Step 6: Commit**
 ```bash
 git add l4d2web/l4d2web/services/timeago.py l4d2web/tests/test_timeago.py
 git commit -m "feat(timeago): symmetric ladder with second precision and date fallback
 Rewrite humanize_delta as a symmetric past/future ladder with
 sub-minute precision. Replace the bare ISO date fallback after 7 days
 with a day-month form (year suppressed when same as now). Refs spec
 docs/superpowers/specs/2026-05-16-timeago-shared-display-design.md."
 ```

 ## Task 2: Add `format_time_html` returning a `<time>` element
 **Files:**
 - Modify: `l4d2web/l4d2web/services/timeago.py`
 - Modify: `l4d2web/tests/test_timeago.py`
 - [ ] **Step 1: Append tests for `format_time_html` to the test file**
 Append to `l4d2web/tests/test_timeago.py`:
 ```python
 from markupsafe import Markup
 from l4d2web.services.timeago import format_time_html
 def test_format_time_html_returns_markup():
    then = NOW - timedelta(minutes=5)
    out = format_time_html(then, now=NOW)
    assert isinstance(out, Markup)
 def test_format_time_html_contains_time_element_with_attrs():
    then = datetime(2026, 5, 16, 14, 32, 11, tzinfo=UTC)
    now = then + timedelta(minutes=5)
    out = str(format_time_html(then, now=now))
    assert out.startswith("<time ")
    assert out.endswith("</time>")
    assert 'datetime="2026-05-16T14:32:11+00:00"' in out
    assert 'title="2026-05-16 14:32:11 UTC"' in out
    assert ">5 minutes ago<" in out
 def test_format_time_html_label_matches_humanize_delta():
    then = NOW - timedelta(hours=2)
    label = humanize_delta(then, now=NOW)
    out = str(format_time_html(then, now=NOW))
    assert f">{label}<" in out
 def test_format_time_html_normalises_naive_input_to_utc():
    then_naive = datetime(2026, 5, 16, 14, 32, 11)
    now = datetime(2026, 5, 16, 14, 37, 11, tzinfo=UTC)
    out = str(format_time_html(then_naive, now=now))
    assert 'datetime="2026-05-16T14:32:11+00:00"' in out
    assert 'title="2026-05-16 14:32:11 UTC"' in out
 ```
 - [ ] **Step 2: Run the new tests to verify they fail**
 Run: `pytest l4d2web/tests/test_timeago.py -v -k format_time_html`
 Expected: FAIL with `ImportError: cannot import name 'format_time_html'`.
 - [ ] **Step 3: Implement `format_time_html` in `timeago.py`**
 Append to `l4d2web/l4d2web/services/timeago.py`:
 ```python
 from markupsafe import Markup, escape
 def format_time_html(then: datetime, now: datetime | None = None) -> Markup:
    if now is None:
        now = datetime.now(UTC)
    then_utc = _ensure_utc(then).astimezone(UTC)
    now = _ensure_utc(now)
    label = humanize_delta(then_utc, now=now)
    iso = then_utc.isoformat()
    title = then_utc.strftime("%Y-%m-%d %H:%M:%S UTC")
    return Markup(
        f'<time datetime="{escape(iso)}" title="{escape(title)}">'
        f"{escape(label)}</time>"
    )
 ```
 Note: place the `from markupsafe import Markup, escape` import at the top of the file alongside the existing `from datetime import ...` line — don't leave it inline as written above.
 - [ ] **Step 4: Run the tests to verify they pass**
 Run: `pytest l4d2web/tests/test_timeago.py -v`
 Expected: all tests PASS.
 - [ ] **Step 5: Commit**
 ```bash
 git add l4d2web/l4d2web/services/timeago.py l4d2web/tests/test_timeago.py
 git commit -m "feat(timeago): add format_time_html returning a <time> element
 Wrap humanize_delta in an HTML <time> element with datetime= and
 title= attributes carrying the precise UTC value, so hovering surfaces
 the exact timestamp regardless of the relative label."
 ```

 ## Task 3: Register `timeago` Jinja filter in the Flask app factory
 **Files:**
 - Modify: `l4d2web/l4d2web/app.py:37-58`
 - Modify: `l4d2web/tests/test_timeago.py`
 - [ ] **Step 1: Add a Flask smoke test for the filter**
 There is no shared `app` fixture in this codebase — each test instantiates `create_app` directly (see `l4d2web/tests/test_health.py` for the minimal pattern). Append to `l4d2web/tests/test_timeago.py`:
 ```python
 from flask import render_template_string
 from l4d2web.app import create_app
 def test_timeago_filter_registered_on_app():
    app = create_app({"TESTING": True, "SECRET_KEY": "test"})
    with app.app_context():
        rendered = render_template_string(
            "{{ ts | timeago }}",
            ts=datetime.now(UTC) - timedelta(minutes=3),
        )
    assert "<time " in rendered
    assert "&lt;time" not in rendered
    assert "3 minutes ago" in rendered
 ```
 - [ ] **Step 2: Verify the fixture and the failing assertion**
 Run: `pytest l4d2web/tests/test_timeago.py::test_timeago_filter_registered_on_app -v`
 Expected: FAIL with a Jinja `TemplateSyntaxError: No filter named 'timeago'` (or similar), confirming the filter is not yet registered.
 - [ ] **Step 3: Register the filter in `create_app`**
 In `l4d2web/l4d2web/app.py`:
 Add the import near the other `from l4d2web...` imports at the top:
 ```python
 from l4d2web.services.timeago import format_time_html
 ```
 Inside `create_app`, register the filter immediately after `init_db()` runs and before the `@app.before_request` definitions. Add a single line:
 ```python
    app.add_template_filter(format_time_html, "timeago")
 ```
 - [ ] **Step 4: Run the smoke test to verify it passes**
 Run: `pytest l4d2web/tests/test_timeago.py::test_timeago_filter_registered_on_app -v`
 Expected: PASS.
 - [ ] **Step 5: Run the full test suite to confirm nothing else broke**
 Run: `pytest l4d2web/tests -q`
 Expected: all tests pass.
 - [ ] **Step 6: Commit**
 ```bash
 git add l4d2web/l4d2web/app.py l4d2web/tests/test_timeago.py
 git commit -m "feat(app): register timeago Jinja filter
 Templates can now call {{ ts | timeago }} directly without route-side
 precomputation."
 ```

 ## Task 4: Migrate `admin_users.html` and `blueprints.html`
 **Files:**
 - Modify: `l4d2web/l4d2web/templates/admin_users.html:25-26`
 - Modify: `l4d2web/l4d2web/templates/blueprints.html:17-18`
 Both templates render `created_at` / `updated_at` as raw Python `datetime` repr. No `None` guard needed — these columns are `nullable=False` in `models.py`.
 - [ ] **Step 1: Modify `admin_users.html`**
 Replace lines 25-26 of `l4d2web/l4d2web/templates/admin_users.html`:
 ```jinja
        <td>{{ user.created_at }}</td>
        <td>{{ user.updated_at }}</td>
 ```
 with:
 ```jinja
        <td>{{ user.created_at | timeago }}</td>
        <td>{{ user.updated_at | timeago }}</td>
 ```
 - [ ] **Step 2: Modify `blueprints.html`**
 Replace lines 17-18 of `l4d2web/l4d2web/templates/blueprints.html`:
 ```jinja
        <td>{{ blueprint.created_at }}</td>
        <td>{{ blueprint.updated_at }}</td>
 ```
 with:
 ```jinja
        <td>{{ blueprint.created_at | timeago }}</td>
        <td>{{ blueprint.updated_at | timeago }}</td>
 ```
 - [ ] **Step 3: Run the existing tests for these pages**
 Run: `pytest l4d2web/tests/test_admin_users.py l4d2web/tests/test_blueprints.py -q`
 Expected: all tests pass. If a test asserts on the raw datetime string in the rendered HTML, update it to assert the presence of `<time ` for the same row instead.
 - [ ] **Step 4: Commit**
 ```bash
 git add l4d2web/l4d2web/templates/admin_users.html l4d2web/l4d2web/templates/blueprints.html
 git commit -m "refactor(templates): use timeago filter for admin/blueprint timestamps"
 ```
 ---
 ## Task 5: Migrate `_job_table.html` and `job_detail.html` (with `None` guards)
 **Files:**
 - Modify: `l4d2web/l4d2web/templates/_job_table.html:22-23`
 - Modify: `l4d2web/l4d2web/templates/job_detail.html:24-26`
 In `models.py`, `Job.started_at` and `Job.finished_at` are nullable; `Job.created_at` is not. Preserve the existing `-` placeholder for nullable columns.
 - [ ] **Step 1: Modify `_job_table.html`**
 Replace lines 22-23 of `l4d2web/l4d2web/templates/_job_table.html`:
 ```jinja
      <td>{{ job.created_at }}</td>
      <td>{{ job.finished_at or "-" }}</td>
 ```
 with:
 ```jinja
      <td>{{ job.created_at | timeago }}</td>
      <td>{% if job.finished_at %}{{ job.finished_at | timeago }}{% else %}-{% endif %}</td>
 ```
 - [ ] **Step 2: Modify `job_detail.html`**
 Replace lines 24-26 of `l4d2web/l4d2web/templates/job_detail.html`:
 ```jinja
      <tr><th>Created</th><td>{{ job.created_at }}</td></tr>
      <tr><th>Started</th><td>{{ job.started_at or "-" }}</td></tr>
      <tr><th>Finished</th><td>{{ job.finished_at or "-" }}</td></tr>
 ```
 with:
 ```jinja
      <tr><th>Created</th><td>{{ job.created_at | timeago }}</td></tr>
      <tr><th>Started</th><td>{% if job.started_at %}{{ job.started_at | timeago }}{% else %}-{% endif %}</td></tr>
      <tr><th>Finished</th><td>{% if job.finished_at %}{{ job.finished_at | timeago }}{% else %}-{% endif %}</td></tr>
 ```
 - [ ] **Step 3: Run the job-related tests**
 Run: `pytest l4d2web/tests/test_job_logs.py l4d2web/tests/test_pages.py -q`
 Expected: all tests pass. Update assertions that pin raw-datetime substrings to instead assert `<time `; the `-` placeholder for nullable fields must still render in the absence of `started_at` / `finished_at`.
 - [ ] **Step 4: Commit**
 ```bash
 git add l4d2web/l4d2web/templates/_job_table.html l4d2web/l4d2web/templates/job_detail.html
 git commit -m "refactor(templates): use timeago filter for job timestamps
 Preserves the existing '-' placeholder for nullable started_at /
 finished_at columns."
 ```
 ---
 ## Task 6: Migrate `_live_state.html`
 **Files:**
 - Modify: `l4d2web/l4d2web/templates/_live_state.html:9-11, 30-33, 53-56`
 Three call sites; all use bespoke `(now - x).total_seconds() // …` math. Replace with the filter. The `now` template variable becomes unused inside this file after the rewrite.
 - [ ] **Step 1: Replace the `polled Ns ago` line (lines 9-11)**
 In `l4d2web/l4d2web/templates/_live_state.html`, find:
 ```jinja
    <small class="muted">
      polled {{ ((now - snapshot.last_seen_at).total_seconds() | int) }}s ago
    </small>
 ```
 Replace with:
 ```jinja
    <small class="muted">
      polled {{ snapshot.last_seen_at | timeago }}
    </small>
 ```
 - [ ] **Step 2: Replace the `joined Nm ago` line (line 31)**
 Find:
 ```jinja
        <span class="meta">
          joined {{ ((now - session.joined_at).total_seconds() // 60) | int }}m ago
          · ping {{ session.min_ping }}-{{ session.max_ping }}ms
        </span>
 ```
 Replace with:
 ```jinja
        <span class="meta">
          joined {{ session.joined_at | timeago }}
          · ping {{ session.min_ping }}-{{ session.max_ping }}ms
        </span>
 ```
 - [ ] **Step 3: Replace the `last seen Nm ago` line (line 55)**
 Find:
 ```jinja
        <span class="meta">
          last seen {{ ((now - row.last_seen).total_seconds() // 60) | int }}m ago
        </span>
 ```
 Replace with:
 ```jinja
        <span class="meta">
          last seen {{ row.last_seen | timeago }}
        </span>
 ```
 - [ ] **Step 4: Run the live-state tests**
 Run: `pytest l4d2web/tests/test_servers.py -q`
 Expected: tests pass. The two tests `test_servers_index_renders_live_state_badge` and `test_live_state_fragment_renders_current_and_recent` (server_routes.py:449, 513) render this fragment. If they assert on `Nm ago` substrings, replace those assertions with checks for `<time ` or for the new long-form output (e.g. `joined 5 minutes ago`).
 - [ ] **Step 5: Commit**
 ```bash
 git add l4d2web/l4d2web/templates/_live_state.html
 git commit -m "refactor(templates): use timeago filter in _live_state.html
 Replaces three bespoke (now - x).total_seconds() expressions with the
 shared filter, unifying vocabulary (no more '0m ago' inside the first
 minute) and adding the UTC tooltip."
 ```
 ---
 ## Task 7: Migrate `_server_actions.html` + `_overlay_build_status.html` + `page_routes.py`
 **Files:**
 - Modify: `l4d2web/l4d2web/routes/page_routes.py:240-305, 442-484`
 - Modify: `l4d2web/l4d2web/templates/_server_actions.html:25-32`
 - Modify: `l4d2web/l4d2web/templates/_overlay_build_status.html:7-14`
 The two route helpers currently precompute a string via `humanize_delta`. Replace with raw `datetime` passed under a new key, let the template apply the filter.
 - [ ] **Step 1: Update `_build_server_actions_context` in `page_routes.py`**
 In `l4d2web/l4d2web/routes/page_routes.py`, replace the block at lines 239-305 (function body of `_build_server_actions_context`) so that:
 - Line 240 — remove `from l4d2web.services.timeago import humanize_delta`.
 - Line 284 — rename `latest_job_when: str | None = None` to `latest_job_at: datetime | None = None`.
 - Line 294 — replace `latest_job_when = humanize_delta(ref_time)` with `latest_job_at = ref_time`.
 - Line 303 — update the returned dict key from `"latest_job_when": latest_job_when` to `"latest_job_at": latest_job_at`.
 `datetime` is already imported at `page_routes.py:2` (`from datetime import UTC, datetime, timedelta`) — no import change needed.
 - [ ] **Step 2: Update `_build_overlay_build_status_context` in `page_routes.py`**
 In the same file, replace the block at lines 442-484 (function body of `_build_overlay_build_status_context`) so that:
 - Line 443 — remove `from l4d2web.services.timeago import humanize_delta`.
 - Line 467 — rename `latest_build_when: str | None = None` to `latest_build_at: datetime | None = None`.
 - Line 475 — replace `latest_build_when = humanize_delta(ref_time)` with `latest_build_at = ref_time`.
 - Line 481 — update the returned dict key from `"latest_build_when": latest_build_when` to `"latest_build_at": latest_build_at`.
 - [ ] **Step 3: Update `_server_actions.html`**
 In `l4d2web/l4d2web/templates/_server_actions.html`, line 29, replace:
 ```jinja
    {{ latest_job_when }}
 ```
 with:
 ```jinja
    {{ latest_job_at | timeago }}
 ```
 - [ ] **Step 4: Update `_overlay_build_status.html`**
 In `l4d2web/l4d2web/templates/_overlay_build_status.html`, line 11, replace:
 ```jinja
    {{ latest_build_when }}
 ```
 with:
 ```jinja
    {{ latest_build_at | timeago }}
 ```
 - [ ] **Step 5: Run the test suite to catch context-key mismatches**
 Run: `pytest l4d2web/tests -q`
 Expected: tests pass. The most likely failure point is tests that check the rendered server actions fragment (`test_servers.py`) or overlay build status fragment. If any test asserts the old `latest_job_when` string output, update it to look for `<time ` or the new long-form output (e.g. `12 minutes ago`).
 - [ ] **Step 6: Commit**
 ```bash
 git add l4d2web/l4d2web/routes/page_routes.py l4d2web/l4d2web/templates/_server_actions.html l4d2web/l4d2web/templates/_overlay_build_status.html
 git commit -m "refactor(page_routes): pass datetime to templates for timeago filter
 Drop the inline humanize_delta imports and string-precomputation; pass
 the raw datetime as latest_job_at / latest_build_at and let the
 template apply the timeago filter. One fewer code path computing
 relative-time strings."
 ```

 ## Task 8: Drop the dead `now=` kwarg from `_live_state.html` render call
 **Files:**
 - Modify: `l4d2web/l4d2web/routes/server_routes.py:266-275`
 After Task 6, `_live_state.html` no longer reads `now`. Remove the kwarg from the only `render_template` call that passes it.
 - [ ] **Step 1: Confirm no other template uses the `now` context variable**
 Run: `grep -rn "\\bnow\\b" l4d2web/l4d2web/templates/`
 Inspect the output. The only references should be in template *files* that we have already migrated. Expected: no remaining `(now - …)` or bare `{{ now }}` references in any template.
 - [ ] **Step 2: Remove the `now=` kwarg**
 In `l4d2web/l4d2web/routes/server_routes.py`, at line 273 inside the `render_template("_live_state.html", …)` call, remove the line:
 ```python
        now=datetime.now(UTC).replace(tzinfo=None),
 ```
 - [ ] **Step 3: Check whether `datetime` and `UTC` are still used in the file**
 If lines 210 and 234 still reference `datetime.now(UTC).replace(tzinfo=None)` (for the `cutoff` and `recent_cutoff` variables), the imports stay. Don't remove them speculatively.
 - [ ] **Step 4: Run the test suite**
 Run: `pytest l4d2web/tests -q`
 Expected: all tests pass. If a test passes a fake `now` into the live-state context expecting it to be respected, that test relied on dead code and should be updated to assert against `<time ` output relative to a real `datetime.now(UTC)` reference.
 - [ ] **Step 5: Commit**
 ```bash
 git add l4d2web/l4d2web/routes/server_routes.py
 git commit -m "refactor(server_routes): drop unused 'now' kwarg from _live_state render
 After the timeago migration, the live-state template no longer reads
 'now' — it computes relative labels through the filter, which derives
 its own reference time."
 ```
 ---
 ## Task 9: End-to-end verification
 **Files:** none — verification only.
 - [ ] **Step 1: Run the entire test suite**
 Run: `pytest l4d2web/tests -q`
 Expected: all tests pass.
 - [ ] **Step 2: Run ruff if it's part of the project's check workflow**
 Run: `ruff check l4d2web/`
 Expected: no new violations. The `.ruff_cache/` directory at the project root suggests ruff is in active use.
 - [ ] **Step 3: Confirm no remaining raw-datetime renders or bespoke inline-time math**
 Run: `grep -rn -E "\\{\\{ [a-z_.]+\\.(created_at|updated_at|started_at|finished_at|joined_at|last_seen|last_seen_at)" l4d2web/l4d2web/templates/`
 Expected: every match is followed by `| timeago` or `| timeago }}{% else %}…{% endif %}`. No bare `{{ x.created_at }}` should remain.
 Run: `grep -rn "(now -" l4d2web/l4d2web/templates/`
 Expected: no matches.
 - [ ] **Step 4: Manual UI smoke (developer-side, optional but recommended)**
 Start the dev server (see `README.md` for the exact command) and log in:
 - Visit `/admin/users` — `Created` / `Updated` columns render `<time>` elements; hovering shows UTC.
 - Visit `/blueprints` — same.
 - Visit `/jobs` and a single job detail — `Created` / `Started` / `Finished` use the filter; null `Finished` shows `-`.
 - Open a server with live state — `polled N seconds ago`, `joined N minutes ago`, `last seen N minutes ago`; check that page-source shows `<time` markup, not literal `&lt;time&gt;`.
 - [ ] **Step 5: No-op commit not required — work is already committed across Tasks 1-8.**
 End of plan.

 # Shared relative-time display helper (spec)
 > Brainstorm scratch artifact. On approval, copy to
 > `docs/superpowers/specs/2026-05-16-timeago-shared-display-design.md`
 > and commit (per `AGENTS.md` planning-artifact convention).
 ## Context
 `left4me`'s web UI renders datetimes inconsistently. Three styles coexist:
 1. **Raw Python `datetime` repr** in admin/blueprint/job tables
   (`admin_users.html`, `blueprints.html`, `_job_table.html`,
   `job_detail.html`) — unfriendly for users.
 2. **Bespoke inline math** in `templates/_live_state.html` — three
   expressions of the form `((now - x).total_seconds() // 60) | int }}m ago`
   with their own vocabulary (`12s ago`, `0m ago` inside the first minute,
   no singular handling).
 3. **Centralised but Python-side** `humanize_delta` (in
   `l4d2web/l4d2web/services/timeago.py`) called from `page_routes.py` for
   `latest_job_when` and `latest_build_when`. Correct output but only
   reachable by route-side precomputation, so adoption is friction-heavy.
 The existing `humanize_delta` also has three design gaps that make it
 unsuitable as the single source of truth:
 - No sub-minute precision (under 45s it returns `just now`, hiding the
  detail `_live_state.html` cares about).
 - Future timestamps are clamped to `just now` (latent bug).
 - Falls back to a bare ISO date (`2025-04-21`) after 7 days, which
  reads awkwardly next to relative siblings.
 This spec unifies the three styles behind one Jinja filter, fixes the
 ladder, and leaves a known follow-up.
 ## Goal
 Every user-facing datetime in `l4d2web` templates flows through one
 filter, `{{ ts | timeago }}`, producing a self-describing HTML `<time>`
 element that combines a friendly relative label with a precise tooltip.
 ## Contract
 A single Jinja filter `timeago` returns a `markupsafe.Markup` wrapping
 an HTML `<time>` element:
 ```html
 <time datetime="2026-05-16T14:32:11+00:00"
      title="2026-05-16 14:32:11 UTC">5 minutes ago</time>
 ```
 - `datetime=` carries the ISO 8601 form with explicit timezone offset.
 - `title=` is the hover tooltip — human-readable UTC string.
 - The text node is the relative label produced by the ladder below.
 ### Ladder (long form, symmetric for past and future)
 | `abs(delta)` | Past label | Future label |
 |---|---|---|
 | `0` (sub-second) | `now` | `now` |
 | `< 60s` | `1 second ago` / `N seconds ago` | `in 1 second` / `in N seconds` |
 | `< 60m` | `1 minute ago` / `N minutes ago` | `in 1 minute` / `in N minutes` |
 | `< 24h` | `1 hour ago` / `N hours ago` | `in 1 hour` / `in N hours` |
 | `< 7d` | `1 day ago` / `N days ago` | `in 1 day` / `in N days` |
 | `≥ 7d`, same year as `now` | `16 Feb` | `30 May` |
 | `≥ 7d`, different year | `16 May 2025` | `16 May 2027` |
 - Singular form when the leading number is exactly `1`.
 - Day-first English month abbreviation (`16 Feb`, not `Feb 16`).
 - Year suppressed only when `then.year == now.year`.
 - `then.day` rendered without leading zero (use `then.day` directly,
  not `%d`, for portability).
 ### Defensive input handling
 - `then.tzinfo is None` → assume UTC (preserves current behaviour and
  works against today's naive-UTC SQLite columns; becomes a harmless
  no-op once the follow-up cleanup lands).
 - `now` defaults to `datetime.now(UTC)` and is similarly normalised.
 - `None` is **not** accepted — callers guard nullable columns with
  `{% if x %}{{ x | timeago }}{% else %}-{% endif %}`.
 ## Module shape
 File: `l4d2web/l4d2web/services/timeago.py` (existing).
 Two callables, one source of truth for the ladder:
 - `humanize_delta(then: datetime, now: datetime | None = None) -> str`
  — pure text; ladder above. Kept for non-HTML callers (e.g. log lines,
  emails) and for unit-testing the label logic in isolation.
 - `format_time_html(then: datetime, now: datetime | None = None) -> Markup`
  — wraps `humanize_delta` in the `<time>` element. UTC-normalises
  `then` for the `datetime=` and `title=` attributes. Escapes the
  title via `markupsafe.escape` (defensive — ISO strings carry no
  HTML-special characters, but the explicit call is free and keeps the
  helper trustworthy if its inputs ever grow).
 Register `format_time_html` as Jinja filter `timeago` in the Flask app
 factory.
 ## Files to modify
 ### Helper + registration
 - `l4d2web/l4d2web/services/timeago.py` — rewrite `humanize_delta` to
  the symmetric ladder with sub-minute precision and future support;
  add `format_time_html`.
 - Flask app factory (locate during implementation; likely
  `l4d2web/l4d2web/app.py` or `__init__.py`) — register
  `format_time_html` as filter `timeago`:
  `app.add_template_filter(format_time_html, "timeago")`.
 ### Templates (replace raw datetimes / bespoke math)
 - `l4d2web/l4d2web/templates/admin_users.html:25-26`
 - `l4d2web/l4d2web/templates/blueprints.html:17-18`
 - `l4d2web/l4d2web/templates/_job_table.html:22-23`
 - `l4d2web/l4d2web/templates/job_detail.html:24-26`
 - `l4d2web/l4d2web/templates/_live_state.html:10, 31, 55`
 For nullable columns (`finished_at`, `started_at`,
 `last_downloaded_at`), preserve the current `-` placeholder:
 ```jinja
 {% if job.finished_at %}{{ job.finished_at | timeago }}{% else %}-{% endif %}
 ```
 ### Routes
 - `l4d2web/l4d2web/routes/page_routes.py:240, 294, 443, 475` — drop
  the inline `humanize_delta` imports and `latest_job_when` /
  `latest_build_when` precomputation. Pass the raw `datetime` into the
  template context (rename keys to `latest_job_at` / `latest_build_at`
  for type-honesty) and let the templates call `| timeago`.
 ### `_live_state.html` `now` parameter
 After the rewrite, check whether the `now` context variable is still
 referenced anywhere in `_live_state.html`. If not, remove it from the
 template render call (likely in `page_routes.py` and `server_routes.py`)
 and from whichever helper builds the live-state context. Dead-code
 cleanup, not behaviour change.
 ## Files to read for context during implementation
 - `l4d2web/l4d2web/services/timeago.py:1-29` — current ladder, the
  function we're extending.
 - `l4d2web/l4d2web/models.py:22-23` — `now_utc()` factory.
 - `l4d2web/l4d2web/routes/profile_routes.py:86-88` — documented
  workaround comment that explains why naive datetimes exist
  (informs the defensive `tzinfo is None` line).
 - `l4d2web/l4d2web/routes/page_routes.py:240-294, 443-475` — the
  existing precomputation pattern being removed.
 ## Testing
 ### Unit tests (`l4d2web/tests/test_timeago.py`, new file)
 Parameterised boundary coverage for `humanize_delta`:
 | Input delta | Expected |
 |---|---|
 | `0` | `now` |
 | `+1s` past | `1 second ago` |
 | `+2s` past | `2 seconds ago` |
 | `+59s` past | `59 seconds ago` |
 | `+60s` past | `1 minute ago` |
 | `+1m` past | `1 minute ago` |
 | `+59m past` | `59 minutes ago` |
 | `+60m past` | `1 hour ago` |
 | `+23h past` | `23 hours ago` |
 | `+24h past` | `1 day ago` |
 | `+6d past` | `6 days ago` |
 | `+7d past`, same year | date form (e.g. `now=2026-02-23` → `16 Feb`) |
 | `+1y past`, different year | date form with year (e.g. `now=2026-05-16` → `16 May 2025`) |
 | `-1s` future | `in 1 second` |
 | `-59s` future | `in 59 seconds` |
 | `-60s` future | `in 1 minute` |
 | `-1d` future | `in 1 day` |
 | `-7d` future, same year | date form |
 | `-1y` future, different year | date form |
 Plus:
 - Naive input → treated as UTC; no `TypeError`.
 - Same-year vs different-year branch.
 - Year-boundary edge: `then = 2025-12-30`, `now = 2026-01-02` →
  `16 May 2025`-style with year (because years differ).
 ### `format_time_html` tests
 - Returns `markupsafe.Markup`.
 - Contains `<time datetime="..." title="...">...</time>`.
 - `datetime=` attribute is ISO 8601 with `+00:00` offset.
 - `title=` matches `YYYY-MM-DD HH:MM:SS UTC`.
 - Label inside element equals `humanize_delta(then, now)`.
 ### Smoke test (Flask test client)
 Render a minimal template `{{ ts | timeago }}` via the test client and
 assert:
 - Response contains `<time` (filter is registered).
 - No literal `&lt;time&gt;` (no double-escaping).
 ## Verification
 End-to-end checks before declaring done:
 1. `pytest l4d2web/tests -q` — full suite green, including the new
   `test_timeago.py`.
 2. Manual UI walk in a logged-in session:
   - `/admin/users` — `Created` / `Updated` columns show "N minutes
     ago" / date form.
   - `/blueprints` — same.
   - `/jobs` (and a single job detail) — `Created` / `Started` /
     `Finished` use the filter; null `Finished` still shows `-`.
   - A server with live state — `polled N seconds ago`,
     `joined N minutes ago`, `last seen N minutes ago`.
 3. Hover one of the new `<time>` elements — browser-native tooltip
   shows the UTC string.
 4. Check page source — no double-escaped tags; `<time>` element
   present with both attributes.
 ## Out of scope
 - Switching `models.py` DateTime columns to `timezone=True` and
  removing the ~6 `replace(tzinfo=None)` workarounds. Worth doing,
  but mechanical and separable. See follow-up below.
 - Client-side ticker JS to keep visible labels fresh on long-open
  tabs. The tooltip carries the precise UTC value; HTMX-polled pages
  refresh anyway.
 - Duration formatting (`running for 12 minutes`). The helper renders
  points in time, not intervals.
 - Localisation. English month names everywhere, matching the rest of
  the app's strings.
 ## Follow-up spec (file separately after this lands)
 `docs/superpowers/specs/YYYY-MM-DD-naive-datetime-cleanup-design.md` —
 switch `models.py` `DateTime` columns to `DateTime(timezone=True)`,
 remove the `.replace(tzinfo=None)` workarounds in
 `profile_routes.py:88`, `server_routes.py:210/234/273`,
 `page_routes.py:174`, `live_state_poller.py:37`, and confirm auth
 markers, staleness comparisons, and session helpers still work.
 Mechanical refactor, no behaviour change visible to users. The
 `timeago` helper's defensive `tzinfo is None` line becomes a no-op
 afterwards — leave it as a safety net.
